Do stem cell injections for knee osteoarthritis actually work?

<div class="theconversation-article-body">More than 500 million people around the world <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00163-7/fulltext">live with osteoarthritis</a>. The knee is affected more often than any other joint, with symptoms (such as pain, stiffness and reduced movement) affecting work, sleep, sport and <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">daily activities</a>.</p> <p>Knee osteoarthritis is often thought of as thinning of the protective layer of cartilage within the joint. But we now understand it affects all the structures of the joint, including the bones, muscles and nerve endings.</p> <p>While there are things that <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard/information-consumers-osteoarthritis-knee-clinical-care-standard">can be done to manage</a> the symptoms of knee osteoarthritis, there is no cure, and many people experience persistent pain. As a result, an opportunity exists for <a href="https://www.rheuma.com.au/stem-cell-therapy-good-bad-ugly/174">as yet unproven treatments</a> to enter the market, often before regulatory safeguards can be put in place.</p> <p>Stem cell injections are one such treatment. A <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013342.pub2">new review</a> my colleagues and I published this week finds that evidence of their benefits and harms remains elusive.</p> <h2>Stem cell treatments</h2> <p>Stem cells are already established as treatments for some diseases – <a href="https://www.lymphoma.org.au/lymphoma/treatments/stem-cell-transplants/autologous-stem-cell-transplant/">mostly disorders of the blood</a>, bone marrow or immune system – which has led to suggestions they could be used for a much wider array of conditions.</p> <p>Stem cells have been touted as promising treatments for osteoarthritis because they have special properties which allow them to replicate and develop into the mature healthy cells that make up our body’s organs and other tissues, including cartilage.</p> <p>Stem cell treatments for osteoarthritis generally involve <a href="https://www.aboutstemcells.org/treatments">taking a sample of tissue</a> from a site that is rich in stem cells (such as bone marrow or fat), treating it to increase the number of stem cells, then injecting it into the joint.</p> <p>The hope is that if the right type of stem cells can be introduced into an osteoarthritic joint in the right way and at the right time, they may help to repair damaged structures in the joint, or have other effects such as reducing inflammation.</p> <p>But no matter how convincing the theory, we need good evidence for effectiveness and safety before a new therapy is adopted into practice.</p> <p>Stem cell injections have not been approved by Australia’s <a href="https://www.tga.gov.au/news/news/stem-cell-treatments-and-regulation-quick-guide-consumers#:%7E:text=Does%20the%20TGA%20regulate%20stem,does%20not%20regulate%20medical%20practice">Therapeutic Goods Administration</a> for the treatment of osteoarthritis. Nonetheless, some clinics in Australia and around the world still offer them.</p> <p>Because of the regulatory restrictions, we don’t have reliable numbers on how many procedures are being done.</p> <p>They’re not covered by Medicare, so the procedure can cost the consumer thousands of dollars.</p> <p>And, as with any invasive procedure, both the <a href="https://coroners.nsw.gov.au/documents/findings/2016/Findings%20Drysdale.pdf">harvest of stem cells</a> and the joint injection procedure may carry the potential for harm, such as infection.</p> <h2>What we found</h2> <p>Our <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013342.pub2">new review</a>, published by the independent, international group the Cochrane Collaboration, looks at all 25 randomised trials of stem cell injections for knee osteoarthritis that have been conducted worldwide to date. Collectively, these studies involved 1,341 participants.</p> <p>We found stem cell injections may slightly improve pain and function compared with a placebo injection, but the size of the improvement may be too small for the patient to notice.</p> <p>The evidence isn’t strong enough to determine whether there is any improvement in quality of life following a stem cell injection, whether cartilage regrows, or to estimate the risk of harm.</p> <p>This means we can’t confidently say yet whether any improvement that might follow a stem cell injection is worth the risk (or the cost).</p> <h2>Hope or hype?</h2> <p>It’s not surprising we invest hope in finding a transformative treatment for such a common and disabling condition. Belief in the benefits of stem cells is widespread – more than <a href="https://www.arthroscopyjournal.org/article/S0749-8063(21)00571-5/abstract">three-quarters of Americans</a> believe stem cells can relieve arthritis pain and more than half believe this treatment to be curative.</p> <p>But what happens if a new treatment is introduced to practice before it has been clearly proven to be safe and effective?</p> <p>The use of an unproven, invasive therapy is not just associated with the risks of the intervention itself. Even if the treatment were harmless, there is the risk of unnecessary cost, inconvenience, and a missed opportunity for the patient to use existing therapies that are known to be effective.</p> <p>What’s more, if we need to play catch-up to try to establish an evidence base for a treatment that’s already in practice, we risk diverting scarce research resources towards a therapy that may not prove to be effective, simply because the genie is out of the bottle.</p> <h2>Working towards a clearer answer</h2> <p>Several more large <a href="https://anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12620000870954">clinical trials</a> are currently underway, and should increase our understanding of whether stem cell injections are safe and effective for knee osteoarthritis.</p> <p>Our review incorporates “<a href="https://www.cochrane.org/news/cochranes-pioneering-role-living-evidence">living evidence</a>”. This means we will continue to add the results of new trials as soon as they’re published, so the review is always up to date, and offers a comprehensive and trustworthy summary to help people with osteoarthritis and their health-care providers to make informed decisions.</p> <p>In the meantime, there are a number of <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/key-racgp-guidelines/view-all-racgp-guidelines/knee-and-hip-osteoarthritis/summary-plain-language">evidence-based treatment options</a>. Non-drug treatments such as physiotherapy, regular exercise, maintaining a healthy weight, and cognitive behavioural therapy can be more effective than you think. Anti-inflammatory and pain medications can also play a supporting role.</p> <p>Importantly, it’s not inevitable that osteoarthritic joints get worse with time. So, even though <a href="https://aoanjrr.sahmri.com/background">joint replacement surgery</a> is often highly effective, it’s the last resort and fortunately, many people never need to take this step.<!-- Below is The Conversation's page counter tag.

Do any non-drug treatments help back pain? Here’s what the evidence says

<div class="theconversation-article-body"> <p>Jason, a 42-year-old father of two, has been battling back pain for weeks. Scrolling through his phone, he sees ad after ad promising relief: chiropractic alignments, acupuncture, back braces, vibrating massage guns and herbal patches.</p> <p>His GP told him to “stay active”, but what does that even mean when every movement hurts? Jason wants to avoid strong painkillers and surgery, but with so many options (and opinions), it’s hard to know what works and what’s just marketing hype.</p> <p>If Jason’s experience sounds familiar, you’re not alone. Back pain is one of the most common reasons people visit a doctor. It can be challenging to manage, mainly due to widespread <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">misunderstandings</a> and the <a href="https://ebm.bmj.com/content/early/2025/03/02/bmjebm-2024-112974">overwhelming number</a> of ineffective and uncertain treatments promoted.</p> <p>We assessed the best available evidence of non-drug and non-surgical treatments to alleviate low back pain. <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">Our review</a> – published today by the independent, international group the Cochrane Collaboration – includes 31 Cochrane systematic reviews, covering 97,000 people with back pain.</p> <p>It <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">shows</a> bed rest doesn’t work for back pain. Some of the treatments that do work can depend on how long you’ve been in pain.</p> <h2>Is back pain likely to be serious?</h2> <p>There are different types of low back pain. It can:</p> <ul> <li>be short-lived, lasting less than six weeks (acute back pain)</li> <li>linger for a bit longer, for six to twelve weeks (sub-acute)</li> <li>stick around for months and even years (chronic, defined as more than 12 weeks).</li> </ul> <p>In <a href="https://www.thelancet.com/article/S0140-6736(16)30970-9/abstract">most cases</a> (90-95%), back pain is non-specific and cannot be reliably linked to a specific cause or underlying disease. This includes common structural changes seen in x-rays and MRIs of the spine.</p> <p>For this reason, imaging of the back is <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(09)60172-0/abstract">only</a> recommended in rare situations – typically when there’s a clear suspicion of serious back issues, such as after physical trauma or when there is numbness or loss of sensation in the groin or legs.</p> <p>Many people expect to receive <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013815.pub2/full">painkillers</a> for their back pain or even surgery, but these are no longer the front-line treatment options due to limited benefits and the high risk of harm.</p> <p>International <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)30489-6/fulltext">clinical guidelines</a> recommend people choose non-drug and non-surgical treatments to relieve their pain, improve function and reduce the distress commonly associated with back pain.</p> <p>So what works for different types of pain? Here’s what <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014691.pub2/full">our review found</a> when researchers compared these treatments with standard care (the typical treatment patients usually receive) or no treatment.</p> <h2>What helps for short-term back pain</h2> <p><strong>1. Stay active – don’t rest in bed</strong></p> <p>If your back pain is new, the best advice is also one of the simplest: keep moving despite the pain.</p> <p>Changing the way you move and use your body to protect it, or resting in bed, can seem like to right way to respond to pain – and may have even been recommended in the past. But we know know this excessive protective behaviour can make it harder to return to meaningful activities.</p> <p>This doesn’t mean pushing through pain or hitting the gym, but instead, trying to maintain your usual routines as much as possible. Evidence suggests that doing so won’t make your pain worse, and may improve it.</p> <p><strong>2. Multidisciplinary care, if pain lingers</strong></p> <p>For pain lasting six to 12 weeks, multidisciplinary treatment is likely to reduce pain compared to standard care.</p> <p>This involves a coordinated team of doctors, physiotherapists and psychologists working together to address the many factors contributing to your back pain persisting:</p> <ul> <li> <p>neurophysiological influences refer to how your nervous system is currently processing pain. It can make you more sensitive to signals from movements, thoughts, feelings and environment</p> </li> <li> <p>psychological factors include how your thoughts, feelings and behaviours affect your pain system and, ultimately, the experience of pain you have</p> </li> <li> <p>occupational factors include the physical demands of your job and how well you can manage them, as well as aspects like low job satisfaction, all of which can contribute to ongoing pain.</p> </li> </ul> <h2>What works for chronic back pain</h2> <p>Once pain has been around for more than 12 weeks, it can become more difficult to treat. But relief is still possible.</p> <p><strong>Exercise therapy</strong></p> <p>Exercise – especially programs tailored to your needs and preferences – is likely to reduce pain and help you move better. This could include aerobic activity, strength training or Pilates-based movements.</p> <p>It doesn’t seem to matter what type of exercise you do – it matters more that you are consistent and have the right level of supervision, especially early on.</p> <p><strong>Multidisciplinary treatment</strong></p> <p>As with short-term pain, coordinated care involving a mix of physical, occupational and psychological approaches likely works better than usual care alone.</p> <p><strong>Psychological therapies</strong></p> <p>Psychological therapies for chronic pain include approaches to help people change thinking, feelings, behaviours and reactions that might sustain persistent pain.</p> <p>These approaches are likely to reduce pain, though they may not be as effective in improving physical function.</p> <p><strong>Acupuncture</strong></p> <p>Acupuncture probably reduces pain and improves how well you can function compared to placebo or no treatment.</p> <p>While some debate remains about how it works, the evidence suggests potential benefits for some people with chronic back pain.</p> <h2>What doesn’t work or still raises uncertainty?</h2> <p>The review found that many commonly advertised treatments still have uncertain benefits or probably do not benefit people with back pain.</p> <p>Spinal manipulation, for example, has uncertain benefits in acute and chronic back pain, and it likely does not improve how well you function if you have acute back pain.</p> <p>Traction, which involves stretching the spine using weights or pulleys, probably doesn’t help with chronic back pain. Despite its popularity in some circles, there’s little evidence that it works.</p> <p>There isn’t enough reliable data to determine whether advertised treatments – such back braces, vibrating massage guns and herbal patches – are effective.</p> <h2>How can you use the findings?</h2> <p>If you have back pain, start by considering how long you’ve had it. Then explore treatment options that research supports and discuss them with your GP, psychologist or physiotherapist.</p> <p>Your health provider should reassure you about the importance of gradually increasing your activity to resume meaningful work, social and life activities. They should also support you in making informed decisions about which treatments are most appropriate for you at this stage.</p> <p><!-- Below is The Conversation's page counter tag.

Hilarious gift for Home and Away icon after her final scene

<p>After an incredible 33-year run on <em>Home and Away</em>, beloved actress Lynne McGranger has filmed her final scene, marking the end of an era for both the show and its devoted fans. Portraying the iconic Irene Roberts, McGranger’s departure is a moment of celebration and nostalgia for the Australian TV industry.</p> <p>McGranger wrapped up her last scene on the legendary Pier Diner set at Seven’s Eveleigh Studios in Sydney on Wednesday. The emotional moment was met with cheers and heartfelt applause as the cast and crew gathered to witness the final take for the longest-serving female cast member in the show’s history.</p> <p>Producer Lucy Addario led the tributes, presenting McGranger with a bouquet of flowers on behalf of the <em>Home and Away</em> production team. Adding a touch of humour and nostalgia, she was also gifted the famous “Hamburger Phone” – a prop synonymous with the Diner – as a token of appreciation for her unforgettable contribution to the show.</p> <p>Grateful and emotional, McGranger reflected on her incredible journey. “I’ve had the ride of my life. And I love each and every one of you so much: The cast – Ray, Georgie, Emily, Shane, Ada, James, all the youngins,” she said. “The art department, the writers, everybody – there’s so many unsung heroes. This show is made up of so many parts. You’re all amazing, and it’s been my great privilege to work with each and every one of you. I’m touched, I’m humbled, and I’m so honoured. Thank you so much.”</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/DHp-tuUCy-h/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DHp-tuUCy-h/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by 7NEWS Sydney (@7newssyd)</a></p> </div> </blockquote> <p>Though McGranger’s time on set has concluded, her character’s exit storyline promises to keep viewers captivated for months to come.

Why do I grieve my childhood home so much now we’ve sold it?

<div class="theconversation-article-body"> <p>Grief can hit us in powerful and unanticipated ways. You might expect to grieve a person, a pet or even a former version of yourself – but many people are surprised by the depth of sad yearning they can feel after selling the childhood home.</p> <p>In fact, it is <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">normal to grieve a place</a>. And this grief can be especially profound if it coincides with a parent dying or moving into residential aged care, leading to the sale of their house.</p> <p>Grief is the response to the loss of anything to which we have an emotional connection. A <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">growing body</a> of <a href="https://www.taylorfrancis.com/books/mono/10.4324/9780203860731/counting-losses-darcy-harris">research</a> is looking at how grief can extend to “non-person” losses such as infertility, loss of religion and, yes, the loss of a former home.</p> <h2>Why would someone grieve a house?</h2> <p>The childhood home can be an important place for many of us. It literally housed our formative development, family bonds, and core memories. Hopefully, the childhood home is where we learned about safety, security and love.</p> <p>It was likely surrounded by our neighbourhood, and close to important places such as school, playgrounds and friends’ houses. It is no wonder we grieve it when it’s gone.</p> <p>It’s normal to <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9781315126197-20/grieving-lost-home-marc-fried">grieve things we can’t see and touch</a> but are real and valued. Just as a <a href="https://doi.org/10.1002/pon.70031">serious diagnosis might trigger</a> grief for an imagined future for yourself, or an <a href="https://doi.org/10.1177/1049732314538550">identity</a> you once cherished, loss of a childhood home can hit us harder than we think.</p> <p>When you sell a once-beloved home, you don’t just lose the physical space. You also lose all of what that space might represent, such as birthday celebrations, Christmas lunches, sleepovers with friends or many happy hours playing in the garden.</p> <p>The childhood home often is a symbol of family connection and an anchor in the storm of life. Thinking of the home and all it represents can elicit nostalgia. In fact, the word “nostalgia” <a href="https://www.bps.org.uk/psychologist/nostalgia-cowbells-meaning-life">derives from the Greek</a> words <em>nostos</em> (return) and <em>algos</em> (pain). The word is rooted in the pain we often feel being away from home.</p> <p>And just as siblings are unique – each with different memories of and connections to their childhood home – their responses to its sale can differ markedly. It is normal if your sister or brother grieves the home in a different way to you – or maybe doesn’t even seem to grieve its loss at all.</p> <h2>A complicated grief</h2> <p>When a childhood home is sold because of the death of parents, the feelings of loss about the home are closely linked. The home being sold can be a type of secondary loss that sits in the periphery to the primary loss of parents.</p> <p>Grieving the deaths might, at first, take precedence over the loss of the home.</p> <p>It might only be later that the loss of the home and all it represents becomes apparent. Because the home provides a connection to the deceased person, the loss of the home might add another layer of grief about your parents. Perhaps you find that whenever you recall memories of mum or dad, they seem always to be at the house.</p> <p>It’s also normal if you feel immense <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">guilt</a> about grieving the home. People might chastise themselves for worrying about “silly things” and not grieving “enough” about the person who died. <a href="https://www.agingcare.com/questions/how-do-i-deal-with-the-guilt-of-selling-moms-house-481550.htm">Guilt about selling the home</a> can also be common.</p> <p>Not everyone has positive memories of their childhood home. Difficult family dynamics, maltreatment and abuse can complicate the emotional connection to childhood spaces and the grief response to their loss.</p> <p>In such cases, the loss of the childhood home can elicit grief about the loss of the childhood that could have – and should have – been. The loss of a home that was the site of discord can be even more challenging than for people with more idyllic childhood experiences.</p> <h2>How can I cope with this loss?</h2> <p>Grief from the loss of a childhood home is <a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">real and valid</a>. We should recognise this and be kind to ourselves and others experiencing it. We shouldn’t minimise the loss or make fun of it.</p> <p>Usually, the loss is anticipated, and this allows you to take photos, furniture or mementos from the home or garden before you leave or sell.</p> <p>Grief researchers call these “<a href="https://www.sciencedirect.com/science/article/pii/S0010440X20300031">transitional</a> <a href="https://www.tandfonline.com/doi/abs/10.1080/13576270412331329812">objects</a>”. They may help you maintain a connection to what is lost, while still grieving the place.</p> <p><a href="https://link.springer.com/article/10.1007/s10615-018-0682-5">Social support</a> while grieving is important. Some people share memories and photos of the home with their siblings, or derive comfort from driving by the home.</p> <p>Just be prepared for the possibility it will likely change as the new owners adapt it to their needs. You might feel affronted, but hopefully can eventually accept the property now belongs to someone else.</p> <p>Chat to your doctor if the loss is particularly difficult, and your grief doesn’t change and subside over time. They might be able to recommend a psychologist who specialises in grief.</p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, call Lifeline on 13 11 14.</em><!-- Below is The Conversation's page counter tag.

I’m avoiding a hearing test because I don’t want chunky hearing aids. What are my options?

<div class="theconversation-article-body"><a href="https://www.health.gov.au/hearing-health/resources/publications/one-in-six-australians-experience-hearing-loss-poster-0?language=en">One in six Australians</a> have hearing loss and, for most adults, hearing starts to decline from <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0107720">middle age onwards</a>.</p> <p>Many of us, however, hesitate to seek help or testing for our hearing. Perhaps you’re afraid you’ll be told to wear hearing aids, and envision the large and bulky hearing aids you might have seen on your grandparents decades ago.</p> <p>In fact, hearing aids have changed a lot since then. They’re often now very small; some are barely noticeable. And hearing aids aren’t the only option available for people experiencing hearing loss.</p> <h2>Why you shouldn’t ignore hearing loss</h2> <p>Acquired hearing loss can have a serious impact on our life. It is <a href="https://journals.sagepub.com/doi/10.1177/2331216517734088">associated</a> with or can <a href="https://pubmed.ncbi.nlm.nih.gov/29222544/">contribute</a> to:</p> <ul> <li>social isolation</li> <li>loneliness</li> <li>not being able to work as much, or at all</li> <li>memory problems</li> <li>trouble thinking clearly</li> <li>conditions such as dementia.</li> </ul> <p>Hearing loss has also been associated with depression, anxiety and stress. A <a href="https://academic.oup.com/gerontologist/article-abstract/60/3/e137/5369884?redirectedFrom=fulltext">systematic review and meta-analysis</a> found adults with hearing loss are 1.5 times more likely to experience depression than those without hearing loss.</p> <p>A <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2768374">large population study</a> in the US found self-reported hearing loss was associated with:</p> <ul> <li>higher levels of psychological distress</li> <li>increased use of antidepressant and anti-anxiety medications, and</li> <li>greater utilisation of mental health services.</li> </ul> <p>The good news is that doing something about your hearing loss can help you live a <a href="https://pubmed.ncbi.nlm.nih.gov/36385406/">happier</a> and <a href="https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(23)00232-5/fulltext">longer</a> life.</p> <h2>So why don’t people get their hearing checked?</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/17927921/">Research</a> has found adults with hearing loss typically wait ten years to seek help for their hearing.</p> <p>Less than a quarter of those who need hearing aids actually go ahead with them.</p> <p>Hearing declines slowly, so people may perceive their hearing difficulties <a href="https://www.tandfonline.com/doi/full/10.3109/14992027.2013.839888">aren’t concerning</a>. They may feel they’re now used to not being able to hear properly, without fully appreciating the impact it’s having on their life.</p> <p>Some people harbour <a href="https://www.tandfonline.com/doi/full/10.3109/14992027.2013.839888">negative attitudes to hearing aids</a> or don’t think they’ll actually help.</p> <p>Others may have overheard their <a href="https://www.tandfonline.com/doi/full/10.3109/14992027.2013.839888">partner, family or friends</a> say negative things or make jokes about hearing aids, which can put people off getting their hearing checked.</p> <p><a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2293651">Stigma</a> can play a big part.</p> <p>People often associate hearing loss with <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2353862">negative stereotypes</a> such as ageing, weakness and “being different”.</p> <p>Our recent <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2024.2446480">research</a> found that around one in four people never tell anyone about their hearing loss because of experiences of stigma.</p> <p>Adults with hearing loss who experience stigma and choose not to disclose their hearing loss were also likely not to go ahead with hearing aids, we found.</p> <h2>What are my options for helping my hearing?</h2> <p>The first step in helping your hearing is to have a hearing check with a hearing care professional such as an an audiologist. You can also speak to your GP.</p> <p>If you’ve got hearing loss, hearing aids aren’t the only option.</p> <p>Others include:</p> <ul> <li>other assistive listening devices (such as amplified phones, personal amplifiers and TV headphones)</li> <li>doing a short course or program (such as the <a href="https://shrs.uq.edu.au/active-communication-education-ace">Active Communication Education program</a> developed via University of Queensland researchers) aimed at giving you strategies to manage your hearing, for instance, in noisy environments</li> <li>monitoring your hearing with regular checkups</li> <li>strategies for protecting your hearing in future (such as wearing earplugs or earmuffs in loud environments, and not having headphone speakers too loud)</li> <li>a cochlear implant (if hearing loss is severe)</li> </ul> <p>Hearing care professionals should take a <a href="https://www.tandfonline.com/doi/full/10.1080/14992027.2023.2190864">holistic approach</a> to hearing rehabilitation.</p> <p>That means coming up with individualised solutions based on your preferences and circumstances.</p> <h2>What are modern hearing aids like?</h2> <p>If you do need hearing aids, it’s worth knowing there are several different types. All modern hearing aids are extremely small and discrete.</p> <p>Some sit behind your ear, while others sit within your ear. Some look the same as air pods.</p> <p>Some are even completely invisible. These hearing aids are custom fitted to sit deep within your ear canal and contain no external tubes and wires.</p> <p>Some types of hearing aids are more expensive than others, but even the basic styles are discrete.</p> <p>In Australia, children and many adults are eligible for <a href="https://www.health.gov.au/our-work/hearing-services-program/accessing/eligibility">free or subsidised hearing services</a> and many health funds offer hearing aid rebates as part of their extras cover.</p> <p>Despite being small, modern hearing aids have advanced technology including the ability to:</p> <ul> <li>reduce background noise</li> <li>direct microphones to where sound is coming from (directional microphones)</li> <li>use Bluetooth so you can hear audio from your phone, TV and other devices directly in your hearing aids.</li> </ul> <p>When used with a smartphone, some hearing aids can even track your health, detect if you have fallen, and translate languages in real time.</p> <h2>What should I do next?</h2> <p>If you think you might be having hearing difficulties or are curious about the status of your hearing, then it’s a good idea to get a hearing check.</p> <p>The earlier you do something about your hearing, the greater the likelihood that you can prevent further hearing decline and reduce other health risks.</p> <p>And rest assured, there’s a suitable option for everyone.<!-- Below is The Conversation's page counter tag.

‘Don’t panic, do prepare’: why it’s not too late to plan for Cyclone Alfred

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/yetta-gurtner-2337172">Yetta Gurtner</a>, <a href="https://theconversation.com/institutions/james-cook-university-1167">James Cook University</a></em></p> <p>For millions of people in southeast Queensland and northern New South Wales, Cyclone Alfred will be their first experience living through a cyclone. Alfred is forecast to make landfall about 2am on Friday morning.</p> <p>I am a disaster expert based in northern Queensland, which regularly experiences cyclones. In my other role as an acting SES public information officer, I’m heading south to the Gold Coast to help residents prepare and respond.</p> <p>Here’s what I want you to know. First, don’t panic. Second, do prepare.</p> <p>Preparation has several steps. It’s important to clearly assess your specific threat. If you live near the sea, storm surges – where the sea spills inland – could be a significant threat, while flooding might pose a large risk if you live near a river – especially in the few days after Alfred passes. The highest rainfall is likely on Alfred’s southern flank from the Gold Coast down to northern New South Wales.</p> <p>Having enough food, water and medication is vital. Be ready to evacuate too, in case authorities deem it necessary. Check your local council’s disaster website, disaster apps and stay tuned to the ABC, which will run disaster alerts.</p> <figure><iframe src="https://www.youtube.com/embed/EN_yKcjlF20?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The Bureau of Meteorology’s latest update on Cyclone Alfred’s path and likely impact, as of the morning of Wed 5th March.</span></figcaption></figure> <h2>What should I do right now?</h2> <p>If you’re in the <a href="http://www.bom.gov.au/products/IDQ65002.shtml">danger zone</a>, make preparations now, before the full intensity of the cyclone arrives.</p> <p>Tie down loose objects. Clean gutters to avoid overflow from torrential rain. And prepare your “go bag” – a bag of essentials you can throw in the car if authorities tell you to leave immediately. Don’t take too much – just the bare necessities.</p> <p>Buy an AM/FM radio and tune it to ABC National, as you cannot be sure mobile networks will function. Radio is a reliable way to get good information from the ABC, Australia’s designated <a href="https://www.abc.net.au/emergency">emergency channel</a>.</p> <p>Make sure the car is fuelled or charged. If you’ve got a generator, make sure you have fuel and the generator is positioned outside in a well-ventilated area.</p> <p>Water is often unreliable after disasters. Fill your bathtub or front-loader washing machine with water. Put containers of water in your freezer, to keep food cold if the power goes out and as another water source. Plan for days of power outages. Protect windows with plywood, heavy blankets or mattresses. Put a mattress between your car and garage roller door to stop it blowing in.</p> <p>Turn off gas, electricity and solar power.</p> <p>Authorities recommend using sandbags to reduce the chance of water getting in. You can get sacks from hardware stores or council-run emergency centres, if available, who also provide sand. You also need plastic sheeting.</p> <p>If there’s a shortage of sand, you can use garden soil or commercial bagged soil. If you can’t get sacks, large plastic shopping bags will do.</p> <p>Tape strong plastic sheeting around the door or low window where water might get in. This is the barrier that actually keeps water out – sandbags keep it in place.</p> <p>Fill sandbags and lay them <a href="https://www.ses.nsw.gov.au/during-emergency/sandbags">like bricks</a>. Lay one row, and lay the next row offset for strength.</p> <p>Sandbags are good, but they have limits. There’s little point in piling sandbags higher than about 30 centimetres. If floodwaters edge higher, water will get through.</p> <p>Many people have had the unpleasant experience of having effluent come back up through toilets during cyclones and subsequent flooding. To stop this, cover your toilet with plastic sheeting (directly on the porcelain) and put a sandbag on top for weight. Do the same for any drains where water might flow back up.</p> <p>To reduce water damage, put valuable or important items up high, atop tables or bunk beds or upstairs if you have a second storey.</p> <h2>What will it be like when Alfred hits?</h2> <p>When the cyclone first hits, it can be overwhelming. The sound is like a roaring jet engine.</p> <p>If you haven’t been advised to evacuate by authorities, you will be sheltering in place.</p> <p>This means finding the safest room in the house, to avoid damage from flying objects. Choose the smallest room with the fewest windows – a bathroom or a room under the stairs. Basements are very safe, but will be the first affected by water.</p> <p>As the cyclone picks up intensity, set up inside this safe room with your pets and children. Do not leave this room until you have been told it’s safe by authorities.</p> <p>At the centre of strong cyclones is the eye of the storm, which we experience as a period of sudden calm. People often make the mistake of thinking it’s over. But in fact, it’s just a brief reprieve before the intense winds pick up again. Don’t make the mistake of leaving the house – check with authoritative sources.</p> <p>Cyclone Alfred is a <a href="https://www.abc.net.au/news/2025-03-05/cyclone-alfred-unusual-triplet-storm-climate-change-factors/105008704">slow-moving cyclone</a>, which means you might be stuck inside for a while. Be prepared to be inside your house for up to 24 hours, even after the worst has passed. This is because there may well be downed powerlines with live electricity, broken glass, falling trees and so on.</p> <p>For your children (and yourself), being in the cyclone is frightening. Young kids find the sound chilling. You can play music through headphones to help soothe them. Board games, books and puzzles can help pass the time. You will need distraction. Have a bucket in the corner for emergency toilet needs.</p> <p>Keep track of the storm and any emerging dangers through your radio and internet-enabled phone (if still functioning).</p> <h2>What if I have to evacuate?</h2> <p>Authorities are working to set up evacuation centres for people whose homes may not be safe. Authorities will go door-to-door to tell affected residents to leave, as well as broadcasting the information on radio and online.</p> <p>You’re more likely to have to evacuate if your house is on low-lying land near the sea, as a storm surge is likely. How much water is pushed ashore will depend on the tide, but it could be as high as 70cm above the high tide line if we’re unlucky.</p> <p>Evacuations can happen after the cyclone too. Alfred is packing a lot of rain – <a href="https://www.weatherzone.com.au/news/tropical-cyclone-alfred-could-disrupt-afl-and-nrl-matches/1890420">up to a metre</a> in some areas. That’s very likely to cause flooding, both flash floods and rivers breaking their banks.</p> <p>If you are asked to evacuate, you can go to the house of a friend or family member if it’s on higher ground and outside the flood risk zones. Or you can go to a local evacuation centre – check your council website to see where your closest one is. Take as little as possible with you.</p> <p>Many people who choose not to evacuate do so because they’re worried about their pets. This is risky. Some evacuation centres do take pets, so check now. If they don’t, look for other options with friends and family. Staying put after an evacuation order is dangerous.</p> <h2>What will happen after the cyclone?</h2> <p>Cyclone Alfred brings three threats: intense winds, high seas and heavy rain.</p> <p>After the intense winds die down, the seas will be dangerous for days after Alfred. There are coastal hazard warnings for about 1,000km of coastline.</p> <p>Cyclones also often decay into tropical low weather systems, which dump heavy rain for days. This is likely.</p> <p>As you move into recovery phase, don’t relax your guard. In far north Queensland, 16 people have <a href="https://www.abc.net.au/news/2025-03-04/melioidosis-death-toll-rises-in-queensland/105009772">now died</a> after being infected with melioidosis, a bacterium found in mud. The bug is <a href="https://theconversation.com/theres-an-outbreak-of-melioidosis-in-north-queensland-heres-what-to-know-about-this-deadly-mud-bug-250392">more prevalent</a> after heavy rainfall.</p> <p>Wear protective gear such as gloves and face masks when dealing with water-damaged goods and mud, and pay close attention to the latest advice authorities are giving.</p> <p>But remember – don’t panic. We will get through this.<!-- Below is The Conversation's page counter tag.

Home and Away icon bids farewell after 33 years

<p>In news that has sent shockwaves through lounge rooms across the country, Lynne McGranger, the heart and soul of <em>Home and Away</em>, is preparing to hang up her iconic apron and bid farewell to her beloved character, Irene Roberts.</p> <p>After an impressive 33 years of delivering heartfelt performances, dishing out sage advice and reminding every misbehaving local to "listen here, girlie", McGranger will be making her emotional exit later this year.</p> <p>Seven has promised fans that Irene’s departure will be one for the history books – no, not via the usual dramatic Summer Bay methods of freak storms, runaway cars or inexplicable amnesia, but an “emotional exit” that “cannot be missed”.</p> <p>While details are tightly under wraps, we can only speculate: Will Irene sail off into the sunset? Open a surf club for wayward teens? Or finally take that well-earned break from all the Summer Bay chaos and settle somewhere where people aren’t constantly getting lost at sea?</p> <p>Fans, naturally, have been left reeling. Social media has been flooded with messages of heartbreak, nostalgia and a desperate plea for Irene to return – even if only for a guest appearance or as a ghostly vision (a <em>Home and Away</em> classic).</p> <p>Lynne herself has spoken out about the farewell, calling it “bittersweet” to leave a role that has been not just a job, but a family. "After almost 33 years in my dream role and working every day with people I love, respect and whom I now consider family, it’s bittersweet to be closing the chapter on what has been the best and longest gig of my life,” she said.</p> <p>Ever the class act, Lynne expressed gratitude to the crew, writers and, of course, the fans – those who have stuck by Irene through every high, low and dramatic face-off at the Diner.</p> <p>And let’s not forget Irene’s legendary status. <em>TV Week</em> readers ranked her as the second Greatest Australian TV Character of All Time (although we suspect if the voting had been left solely to <em>Home and Away</em> die-hards, she’d have taken the crown).</p> <p>Julie McGauran, <em>Home and Away</em>’s Executive Producer, summed it up best: “Lynne’s extraordinary portrayal of down-to-earth Irene Roberts is why the character is held with such great affection by fans around the world.”</p> <p>Despite wrapping up filming in March, Irene will still grace our screens for months to come – enough time for fans to prepare themselves emotionally (and stock up on tissues). In the meantime, Lynne will return to the stage with her comedy show, "The Grandparents Club", proving that she has no plans to slow down anytime soon.</p> <p>The farewell will undoubtedly be a tearjerker, but if we know anything about Irene Roberts, she’ll be leaving Summer Bay the same way she lived in it: with heart, humour and a no-nonsense attitude.</p> <p>As one fan put it perfectly, "Now listen here, girlie, you are going to be missed soooo much."</p> <p>And that, as they say, is the bottom line.</p> <p><em>Image: Instagram</em></p>

It’s now the first <a href="https://boomsupersonic.com/press-release/boom-supersonic-achieves-supersonic-flight">piloted non-military aircraft to break the sound barrier</a> since the Concorde was retired from service in 2003.</p> <p>It’s the first step in Boom’s ambitious goal to have <a href="https://boomsupersonic.com/united">supersonic airliners carry passengers by 2029</a>.</p> <p>But what exactly is supersonic travel? There are good reasons why it’s not more common, despite the hype.</p> <h2>What is supersonic flight?</h2> <p>The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. To “break the sound barrier” means to fly faster than the speed of sound, with Mach numbers greater than 1.</p> <p>The Mach number is an important ratio: as a plane flies, it disturbs the air in front of it. These disturbances move at the speed of sound. In supersonic flight these disturbances combine to form shock waves around the vehicle.</p> <p>When people say you can see a fighter jet before you hear it, they’re referring to supersonic flight: <a href="https://www.aerotime.aero/articles/top-10-worlds-fastest-fighter-jets">fighter jets can travel at around Mach 2</a>.</p> <p>The sound from the fighter jet is trapped inside its shock wave; until the shock wave moves to your position on the ground, you won’t hear the plane.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=360&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/646302/original/file-20250202-15-d01bme.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=452&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Illustration of how disturbances propagate in subsonic, Mach 1, and supersonic flow.</span> <span class="attribution"><a class="source" href="https://commons.wikimedia.org/wiki/File:Transonico-en.svg">Chabacano/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <h2>The allure of supersonic travel</h2> <p>For efficiency reasons, most passenger jets cruise slightly slower than the speed of sound, at around Mach 0.8 (this is subsonic flight).</p> <p>Boom plans to build <a href="https://boomsupersonic.com/overture">an airliner called Overture</a> that can fly at Mach 1.7. Flying supersonically can drastically decrease flight times. The company claims a trip <a href="https://boomsupersonic.com/flyby/summer-travel-trends-future-travel-onboard-overture">from New York to Rome</a> on Overture could take just four hours and 40 minutes, instead of eight hours.</p> <p>Boom isn’t the only company working on this lofty goal. American firm Spike Aerospace is also developing a supersonic business jet, <a href="https://www.spikeaerospace.com/spike-s-512-supersonic-diplomat/">with the tagline</a> “delivering the world in half the time”.</p> <p>This is the value proposition of supersonic passenger travel.</p> <p>In limited ways, it did already exist in the 20th century. However, due to timing, bad luck and the laws of physics, it didn’t continue.</p> <h2>Remember the Concorde?</h2> <p>Designs for supersonic airliners began in the mid-20th century, and by the 1970s we had supersonic passenger flight.</p> <p>There was the little-known <a href="https://en.wikipedia.org/wiki/Tupolev_Tu-144">Russian Tupolev-144</a> and <a href="https://www.britannica.com/technology/Concorde">Concorde</a>, a Franco-British supersonic airliner operated by British Airways and Air France from 1976 to 2003.</p> <p>Concorde had a capacity of <a href="https://www.heritageconcorde.com/concorde-cabin--passenger-experience">up to 128 passengers</a> and cruised at Mach 2. It regularly travelled from London to New York <a href="https://airandspace.si.edu/stories/editorial/what-happened-concordes">in around three hours</a>. The flights were expensive, mainly shuttling business people and the rich and famous.</p> <h2>Why supersonic passenger flight didn’t take off</h2> <p>Concorde was designed in the 1960s when it seemed like supersonic passenger transport was going to be the next big thing.</p> <p>Instead, the Boeing 747 <a href="https://www.boeing.com/commercial/747-8">entered commercial service in 1970</a>. Cheap, large and efficient airliners like it blew Concorde out of the water.</p> <p>Designed to cruise efficiently at supersonic speeds, Concorde was extremely fuel inefficient when taking off and accelerating. Concorde’s expensive, “<a href="https://phys.org/news/2019-03-concorde-technical-feat-financial-fiasco.html">gas guzzling</a>” nature was a complaint levelled against it for most of its lifetime.</p> <p>A catastrophic <a href="https://www.flightglobal.com/safety/tu-144-crash-puzzle-persists-50-years-after-fatal-paris-display/153782.article">1973 Paris air show crash</a> of the competing Russian airliner, Tupolev Tu-144, also shifted public perception on supersonic flight safety at a time when many airlines were considering whether or not to purchase Concordes.</p> <p><a href="https://www.heritageconcorde.com/airframe-detail">Only 20 Concordes were manufactured</a> out of the <a href="https://simpleflying.com/concorde-orders/">planned 100</a>. It is still disputed today whether Concorde <a href="http://www.concordesst.com/faq.html">ever made money for the airlines who operated it</a>.</p> <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/646303/original/file-20250202-15-gjm1zn.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Illustration of a shock wave propagating from a supersonic aeroplane and hitting the ground to produce a sonic boom.</span> <span class="attribution"><a class="source" href="https://commons.wikimedia.org/wiki/File:Supersonic_shockwave_cone.svg">Cmglee/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <h2>Noise is a real problem for supersonic flight</h2> <p>Remember the fighter jets?

This hurt the Concorde’s potential market, hence its only two regular routes were trans-Atlantic flights principally over the water.</p> <p>The Concorde was also a very loud plane at take off, since it needed a lot of thrust to leave the ground.</p> <figure><iframe src="https://www.youtube.com/embed/3x9hO7n5WiA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Video footage of the final Concorde takeoff from New York’s JFK airport.</span></figcaption></figure> <h2>The future of supersonic travel</h2> <p>A future for supersonic travel relies on solving some or all of the issues Concorde faced.</p> <p><a href="https://www.nasa.gov/mission/quesst/">NASA and Lockheed Martin’s Quesst project</a> aims to show sonic boom can be dissipated to manageable levels.

Modern design methods and modern aerospace materials such as titanium and carbon fibre should also allow Overture and similar craft to weigh much less than Concorde, improving efficiency.</p> <p>While Boom are currently receiving a lot of interest, <a href="https://boomsupersonic.com/overture">with orders from many airlines</a>, Concorde did have similar commitment before it become available. <a href="https://www.heritageconcorde.com/concorde-orders-and-options">Most of it didn’t eventuate</a>.</p> <p>Additionally, Concorde was the product of an analogue era when the idea of flying to London or New York for the day for an important business meeting seemed like a necessary thing. In a world of remote work and video meetings, is there still a need for a supersonic airliner in the 2020s?</p> <p>For now, supersonic airliners like Overture are likely to remain in the realm of the rich and famous, like Concorde did. But with modern technological advances, it will be interesting to see whether supersonic passenger travel once again becomes reality – or even goes mainstream.

Around 3% of us will develop a brain aneurysm in our lives. So what is it and how do you treat it?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/jessica-nealon-1481995">Jessica Nealon</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>Australian radio host Kyle Sandilands announced on air that he <a href="https://www.abc.net.au/news/2025-02-03/kyle-sandilands-brain-aneurysm-diagnosis/104888826">has a brain aneurysm</a> and needs urgent brain surgery.</p> <p>Typically an aneurysm occurs when a part of the wall of an artery (a type of blood vessel) becomes stretched and bulges out.</p> <p>You can get an aneurysm <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/aneurysm">in any blood vessel</a>, but they are most common in the brain’s arteries and the aorta, the large artery that leaves the heart.</p> <p>Many people can have a brain aneurysm and never know. But a brain (or aortic) aneurysm that ruptures and bursts can be fatal.</p> <p>So, what causes a brain aneurysm? And what’s the risk of rupture?</p> <h2>Weakness in the artery wall</h2> <p>Our arteries need strong walls because blood is constantly pumped through them and pushed against the walls.</p> <p>An <a href="https://www.healthdirect.gov.au/aneurysms">aneurysm</a> can develop if there is a weak part of an artery wall.</p> <p>The walls of arteries are made of three layers: an inner lining of cells, a middle layer of muscle and elastic fibres, and a tough outer layer of mostly collagen (a type of protein). Damage to any of these layers causes the wall to become thin and stretched. It can then balloon outward, leading to an aneurysm.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4399795/">Genetics</a> and <a href="https://www.ninds.nih.gov/health-information/disorders/cerebral-aneurysms">certain inherited disorders</a> can cause weak artery walls and brain aneurysms in some people.</p> <p>For all of us, our artery walls become weaker as we age, and brain aneurysms are more common as we get older. The <a href="https://www.ncbi.nlm.nih.gov/books/NBK557867/">average age for a brain aneurysm</a> to be detected is 50 (Sandilands is 53).</p> <p>Females have a higher risk of brain aneurysm than males <a href="https://www.ncbi.nlm.nih.gov/books/NBK507902/">after about age 50</a>. Declining oestrogen around menopause reduces the collagen in the artery wall, causing it to become weaker.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="An illustration showing a brain aneurysm." /><figcaption><span class="caption">A brain aneurysm occurs when a part of the wall of an artery balloons out.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/human-brain-blocking-stroke-aneurysm-disease-2171173339">Alfmaler/Shutterstock</a></span></figcaption></figure> <p>High blood pressure can increase the risk of a brain aneurysm. In someone with high blood pressure, blood inside the arteries is pushed against the walls with greater force.

In atherosclerosis, plaques made mostly of fat build up in arteries and stick to the artery walls. This directly damages the cell lining, and weakens the muscle and elastic fibres in the middle layer of the artery wall.</p> <h2>Several lifestyle factors increase risk</h2> <p>Anything that increases inflammation or causes atherosclerosis or high blood pressure in turn increases your risk of a brain aneurysm.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6527044/">Smoking and heavy drinking</a> affect all of these, and nicotine <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6214667/">directly damages</a> the artery wall.</p> <p>Sandilands mentioned <a href="https://www.news.com.au/entertainment/tv/radio/kyle-sandilands-reveals-shock-health-diagnosis-i-may-be-dead/news-story/62f9f05c6f0a03702632ec8d622cf97a">his cocaine use</a> in discussing his diagnosis.

Kyle and Jackie O's $200 million contract death clause revealed

<p>Kyle Sandilands and Jackie ‘O’ Henderson have revealed the grim death clause in their individual contracts.</p> <p>In November 2023, the longtime KIISFM hosts signed a monster $200 million deal with Australian Radio Network (ARN)  that will see them remain on airwaves until 2034, each pocketing a minimum of $10 million per year.</p> <p>However, added to the whopping sum come a series of unique clauses.</p> <p>Speaking candidly on Thursday morning's show, Kyle and Jackie O opened up about what would happen to the show if one of them were to die, and they each had different stipulations.</p> <p>“They [lawyers] did ring me when they were doing this new deal and said ‘Jackie wants this [death] clause’,” Sandilands said. “I said, ‘I’ve had this for years.’”</p> <p>As part of Henderson’s contract, the host specified she’d want the option to leave the show if Sandilands passed away.</p> <p>“I don’t know if I would want to do it with someone else,” Henderson told her co-host.</p> <p>“Aw, bless you,” Sandilands said, before savagely responding, "We drop your name. I get your income.”</p> <p>“I’d just soldier on without you. I wouldn’t like it, [but] I wouldn’t want to let that great bit of content die on the vine. I’d rather be on-air crying.”</p> <p>Elsewhere, Sandilands said it was stated in his contract he would only fly via private jet or first class if he was required to work overseas, while admitting that many of their contract clauses are "beyond belief”.</p> <p><em>Image credits: KIISFM</em></p>

When news is stressful, how do you balance staying informed with ‘doomscrolling’?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/lisa-harrison-1552123">Lisa Harrison</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p>It all begins innocently – a late-night peek at your favourite social media site before bed. You catch a headline that grabs your attention with “breaking news” you can’t afford to miss.</p> <p>Like following digital breadcrumbs, one click leads to another. Before you know it, you’re tumbling down a rabbit hole of endless updates and emotionally charged social media posts. Two hours later, your shoulders are tense, your stomach is in knots, but you can’t put your phone down.</p> <p>This endless scrolling through bad news – known as “<a href="https://www.health.harvard.edu/mind-and-mood/doomscrolling-dangers">doomscrolling</a>” – sneaks up on us.</p> <p>It’s important to stay in touch with what’s happening in the world. Being informed helps us make better decisions, engage meaningfully in our communities, and respond effectively to changes that affect our lives and those around us.</p> <p>But just like a healthy diet, we must be smart about our news consumption to avoid it <a href="https://theconversation.com/doomscrolling-is-literally-bad-for-your-health-here-are-4-tips-to-help-you-stop-190059">taking a toll on our health</a>.</p> <p>The good news is there are proven ways to stay informed without letting it take over your life. Research shows <a href="https://academic.oup.com/poq/article/84/S1/332/5866766">setting clear boundaries</a> around your news consumption can make a huge difference. So, how can you strike the right balance?</p> <h2>How to set boundaries with news consumption</h2> <p>It’s worth considering why you feel compelled to stay constantly informed. Ask yourself: “will this information change what I can do about it?”.</p> <p>Often, we scroll not because the information is actionable, but because <a href="https://www.sciencedirect.com/science/article/pii/S245195882400071X">we are trying to gain a sense of control</a> in an uncertain world.</p> <p>Research shows scrolling through negative news <a href="https://www.abc.net.au/news/2024-08-29/negative-effects-doomscrolling-young-people-existential-anxiety/104268178">can disrupt your sleep and increase anxiety</a>. To make sure your media consumption is intentional, there are a few steps you can take.</p> <p>Be picky with the news sources you read. Choose a few trusted outlets instead of letting social media algorithms decide what you see. It’s like sticking to a balanced meal plan, but for your mind.</p> <p>While engaging with the news, pay close attention to how you’re feeling. When you notice physical signs of anxiety or emotional distress, that is your cue to take a break.</p> <p>Set aside time earlier in the day with clear boundaries around your news consumption: maybe with your morning coffee or during your lunch break, whatever works for your schedule. Consider implementing a “digital sunset”, too. This is a cut-off time for news and social media, ideally an hour or two before bedtime, to give your mind time to process what you have learned without disrupting your sleep.</p> <p>The world will always be there, but you will be in a better head space to process what is happening.</p> <h2>You don’t have to feel helpless</h2> <p>Taking breaks from consuming news is not burying your head in the sand – it’s practising self care. Studies have shown that <a href="https://www.apa.org/monitor/2022/11/strain-media-overload">people who set healthy boundaries</a> around news consumption are often better equipped to engage meaningfully on important issues and take constructive action when needed.</p> <p>When you check the news, be an active consumer. Instead of endless scrolling:</p> <ul> <li> <p>choose one or two in-depth articles to read thoroughly</p> </li> <li> <p>discuss the news with colleagues, friends and family to process your feelings</p> </li> <li> <p>look for solution-focused news stories that highlight positive change</p> </li> <li> <p>take meaningful action on issues you care about.</p> </li> </ul> <p>There are also various apps and tools that can help you form healthier digital habits. <a href="https://theconversation.com/cant-focus-addicted-to-your-online-world-theres-an-app-for-that-98951">Productivity apps</a> use various approaches to help you stay focused, providing ways to snap you out of mindless scrolling.</p> <p>News curation apps and apps that allow you to save articles to read later can help you establish a balanced news diet, and remove the urgent need to read everything immediately.</p> <p>Many smartphones now come equipped with <a href="https://theconversation.com/rethinking-screen-time-a-better-understanding-of-what-people-do-on-their-devices-is-key-to-digital-well-being-243644">screen time management</a> features, such as Apple’s Screen Time or Android’s Digital Wellbeing. You can use these to monitor your scrolling habits and to manage how much time you spend on social media or news apps.</p> <p>One useful feature is to block apps from use during certain times of day or after you’ve used them for a set amount of time.</p> <h2>Stay mindful, stay engaged</h2> <p>Staying informed doesn’t mean staying constantly connected. By mindfully setting boundaries and using supportive tools, you can keep up with important events while protecting your wellbeing.</p> <p>If you’re trying productivity apps and other tools, start small. Choose one tool that resonates with you rather than trying everything at once. Set realistic goals that fit your life, and use these apps’ insights to understand your habits better.</p> <p>Pay attention to what triggers your doomscrolling and adjust your settings accordingly. Remember, these tools work best when combined with offline activities you enjoy.</p> <p>The goal isn’t to disconnect completely, but to find a sustainable balance between staying informed and maintaining peace of mind. With thoughtful boundaries and the right support tools, you can stay engaged with the world while keeping your mental health intact.<!-- Below is The Conversation's page counter tag.

From the Big Bogan to Larry the Lobster, why do towns build Big Things?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/amy-clarke-248726">Amy Clarke</a>, <a href="https://theconversation.com/institutions/university-of-the-sunshine-coast-1068">University of the Sunshine Coast</a></em></p> <p>Big Things first appeared in Australia in the 1960s, beginning with the <a href="https://sahistoryhub.history.sa.gov.au/things/big-scotsman/">Big Scotsman</a> (1962) in Medindie, South Australia, the <a href="https://bigbanana.com">Big Banana</a> (1964) in Coffs Harbour, New South Wales, and the <a href="https://www.visitnsw.com/destinations/country-nsw/the-murray/tocumwal/attractions/big-murray-cod">Big Murray Cod</a> (1968) in Tocumwal, NSW.</p> <p>These structures were inspired by earlier North American examples, such as <a href="https://lucytheelephant.org">Lucy the Elephant</a> (1882) in New Jersey, and several <a href="https://www.laconservancy.org/learn/historic-places/randys-donuts/">big doughnuts in California</a>.</p> <p>While they differed in subject matter, all aimed to attract the attention of passing motorists: in the 1950s–1960s, private car ownership had soared and highway construction spread.</p> <p>Towns and regions across Australia, <a href="https://ourwayoflife.co.nz/11-iconic-big-thing-statues-around-new-zealand/">New Zealand</a> and North America used oversized landmarks to get travellers to stop, take a photo and hopefully spend money at local businesses.</p> <p>As awareness of these giant landmarks grew, so did the desire of other communities to have their own.</p> <p>Within a few decades, Australia’s Big Things had become a beloved fixture of road trips and summer holidays.</p> <h2>A big cultural impact</h2> <p><a href="https://www.tandfonline.com/doi/full/10.1080/14443058.2022.2144928">My research</a> shows the number of Big Things being constructed in Australia hit an initial peak in the 1980s before experiencing a temporary decline.</p> <p>By the 2000s, however, towns as far afield as Tully in Queensland (<a href="https://www.australiantraveller.com/qld/big-gumboot/">Big Golden Gumboot</a>), Cressy in Tasmania (<a href="https://www.aussietowns.com.au/town/cressy-tas">Big Trout</a>), and Exmouth in Western Australia (<a href="https://www.exmouth.wa.gov.au/news/exmouths-iconic-and-much-loved-crustacean-is-back/358">Big Prawn</a>) were reviving the tradition.</p> <p>Soon, Big Things became firmly entrenched in Australian popular culture: featuring on limited edition <a href="https://www.couriermail.com.au/news/queensland/sunshine-coast/redheads-pay-homage-to-icons/news-story/219026f222830073f4db107759e1145c">Redheads matchboxes</a> (2010), and on sets of <a href="https://australiapostcollectables.com.au/stamp-issues/aussie-big-things">Australia Post stamps </a>(2007 and 2023).</p> <p>But some of the older structures experienced declining popularity: the Big Wool Bales in Hamilton, Victoria (closed 2020), Victoria’s Giant Gippsland Earth Worm in Bass (closed 2020) and the Big Cask Wine in Mourquong, NSW (closed 2012), survive only in holiday photos and people’s memories.</p> <p>Icons like Larry the Lobster (Kingston, SA), the Big Prawn (Ballina, NSW), and the Big Pineapple (Nambour, Queensland) have battled <a href="https://www.nytimes.com/2018/08/30/world/australia/larry-lobster-big-things-sale.html">changes in ownership</a>, <a href="https://www.abc.net.au/news/2009-09-24/council-votes-to-sink-big-prawn/1441452">threat of demolition</a>, and <a href="https://www.theguardian.com/australia-news/article/2024/aug/24/big-pineapple-reopen-queensland-woombye-history">closure</a>.</p> <p>Despite these challenges, and debates over heritage conservation, construction of these giant landmarks has not slowed.</p> <p><a href="https://www.visitnsw.com/destinations/outback-nsw/cobar-area/nyngan/attractions/big-bogan">The Big Bogan</a> was erected in 2015 in Nyngan, NSW, by community members who were eager to encourage visitors to the area.</p> <p>A local progress association in the small town of Thallon in Queensland unveiled William the <a href="https://www.stgeorgeregion.com.au/listing/william-the-wombat/">Big Wombat</a> in 2018, also with the aim to bring attention to the area.</p> <p>Similar hopes were held for the <a href="https://www.queensland.com/au/en/things-to-do/attractions/p-5f72991d4390bc7c02ab8547-the-big-melon">Big Watermelon</a> erected in 2018 (Chinchilla, Queensland), and the Big Tractor (Carnamah, WA) <a href="https://www.abc.net.au/news/2024-10-05/midwest-wa-town-carnamah-unveils-worlds-biggest-tractor/104388496">which opened this year</a>.</p> <p>Through my research, I spoke with many people involved with projects such as these, and they said they’d selected objects that were iconic to their area.</p> <p>This could be a product they specialise in, a local native animal, or, in the case of the Big Bogan, a joke based on the name of nearby Bogan River.</p> <p>Most builders openly acknowledge their primary motivation is to promote the region, attract tourist dollars and investment, and revive towns that have seen better days.</p> <p>But do Big Things actually achieve these goals? Unfortunately, there is no easy answer.</p> <h2>An economic return?</h2> <p>Local economies are complex, as are the reasons people choose to visit. Many Big Things are constructed on the sides of highways that connect Australia’s numerous regional towns.</p> <p>People who stop for photos may not set out with the goal of visiting that Big Thing – it may simply be convenient to take a break there while on the way somewhere else.</p> <p>And if people do stop, it doesn’t guarantee they will spend more than the cost of filling up their car with petrol, if that.</p> <p>Over the years, tourism researchers have developed <a href="https://www.sciencedirect.com/science/article/abs/pii/S1447677021000322">several different models </a>for calculating the impact of rural and regional tourism on local economies.</p> <p>However, none of these approaches has proven to be universally effective. Most scholars agree tourists aren’t likely to travel long distances <a href="https://www.tandfonline.com/doi/abs/10.1080/21568316.2019.1673811">for any one reason</a>.</p> <p>They will consider a range of factors including food and accommodation, and the closeness of numerous attractions. In other words: building a Big Thing won’t guarantee a sustained increase in tourism to the area on its own.</p> <p>Communities should factor this in when considering erection of a Big Thing, especially given the cost of construction.</p> <p>The Big Mango in Bowen <a href="http://www.atlasobscura.com/places/the-big-mango">reportedly cost $A90,000</a> when it was built in 2002, while the organisers of the Big Tractor in Carnamah <a href="https://www.abc.net.au/news/2024-10-05/midwest-wa-town-carnamah-unveils-worlds-biggest-tractor/104388496">raised more than $600,000</a> to cover its price tag.</p> <p>The spread of social media and easy access to media outlets via the internet offers communities another reason to build Big Things, however.</p> <p>Australians are not the only ones fascinated by Big Things, and when a new one is unveiled — or an existing one goes “missing”, as <a href="https://www.bbc.com/news/newsbeat-26324023">the Big Mango did in 2014</a> — it is often covered by the press and then shared online.</p> <p>These giant landmarks are also highly “Instagrammable”: <a href="https://www.dailymail.co.uk/news/article-3039474/The-20-hottest-Australian-attractions-Instagram-revealed-spectacular-Sydney-Opera-House-Twelve-Apostles-don-t-forget-Big-Banana.html">a 2015 survey</a> revealed that six of Australia’s 20 most Instagrammed tourist attractions were Big Things.</p> <p>This sort of coverage doesn’t necessarily guarantee the long-term revival of a town’s economy.</p> <p>But it can help to remind people of the town’s existence, and it gives locals a memorable image on which to build.<!-- Below is The Conversation's page counter tag.

Voluntary assisted dying is legal in Australia – but many of us don’t know

This allows terminally ill adults who are suffering and have decision-making capacity to choose to receive help to die.</p> <p>Victoria’s law was the first, coming into effect <a href="https://theconversation.com/voluntary-assisted-dying-will-soon-be-legal-in-victoria-and-this-is-what-you-need-to-know-111836">in 2019</a>. New South Wales was the last state, with its <a href="https://theconversation.com/voluntary-assisted-dying-is-now-available-in-all-australian-states-how-do-the-nsw-laws-compare-217261">voluntary assisted dying law</a> beginning in late 2023.</p> <p>Voluntary assisted dying will be <a href="https://www.act.gov.au/health/topics/end-of-life-and-palliative-care/voluntary-assisted-dying-in-the-act">allowed in the Australian Capital Territory</a> in November, and a <a href="https://cmc.nt.gov.au/project-management-office/voluntary-assisted-dying">Northern Territory report</a> has recommended it pass a voluntary assisted dying law too.</p> <p>While the vast majority of Australians now live in jurisdictions where voluntary assisted dying is permitted, accessing voluntary assisted dying depends on knowing it’s a legal option. But our <a href="https://www.tandfonline.com/doi/full/10.1080/07481187.2025.2452490">new research</a> suggests many Australians don’t know this.</p> <h2>A study in Queensland</h2> <p>Voluntary assisted dying became legal <a href="https://www.health.qld.gov.au/clinical-practice/guidelines-procedures/voluntary-assisted-dying/explained/overview">in Queensland</a> on January 1, 2023. We conducted <a href="https://eprints.qut.edu.au/255019/">an online survey</a> of 1,000 Queensland adults in mid-2024 to find out if the community knew about this new end-of-life choice.</p> <p>We set quotas for age, gender and geographical location to ensure the people we surveyed represented the overall Queensland population.</p> <p>First, we asked whether people thought voluntary assisted dying was legal in Queensland. Only <a href="https://research.qut.edu.au/voluntary-assisted-dying-regulation/wp-content/uploads/sites/292/2025/01/Do-people-know-VAD-is-legal-Research-briefing.pdf">one-third (33%) correctly identified</a> it was. Of the 67% who didn’t, 41% thought voluntary assisted dying was illegal and 26% said they didn’t know.</p> <p>People who did know voluntary assisted dying was legal had generally found out in one of three ways:</p> <ul> <li> <p>from the media</p> </li> <li> <p>from professional experience (for example, working in health care)</p> </li> <li> <p>from personal experience (for example, knowing someone who had asked about, requested or accessed voluntary assisted dying).</p> </li> </ul> <p>We then told our survey participants voluntary assisted dying was legal in Queensland and asked if they would know how to go about accessing it if they wished to. Only one-quarter (26%) answered yes.</p> <p>The survey also asked people where they might look for information about voluntary assisted dying. Most people said they would seek this information online, but asking health practitioners, especially doctors, was also important.</p> <h2>Legal and cultural barriers</h2> <p>Perhaps it’s not surprising so few members of the surveyed public know voluntary assisted dying is a legal choice. It’s still a relatively new law. But there are <a href="https://onlinelibrary.wiley.com/doi/10.1111/hex.13867">specific barriers</a> in Australia that can prevent people finding out about it.</p> <p>One major barrier is health practitioners are often <a href="https://onlinelibrary.wiley.com/doi/10.5694/mja2.52183">not able to freely discuss</a> voluntary assisted dying with their patients. The laws in all states control how conversations about voluntary assisted dying can occur.</p> <p>For example, in Queensland, only doctors and nurse practitioners <a href="https://classic.austlii.edu.au/au/legis/qld/consol_act/vada2021302/s7.html">can raise voluntary assisted dying</a> and only if they also discuss available treatment and palliative care options and their likely outcomes.</p> <p>But the most problematic are <a href="https://classic.austlii.edu.au/au/legis/vic/consol_act/vada2017302/s8.html">Victorian</a> and <a href="https://www.austlii.edu.au/cgi-bin/viewdoc/au/legis/sa/consol_act/vada2021302/s12.html">South Australian</a> laws which prohibit health practitioners from raising the topic with patients altogether. Many people rely on their doctor to tell them about treatment options, so it’s a problem if the onus is on the patient to bring it up first.</p> <p><a href="https://onlinelibrary.wiley.com/doi/10.5694/mja2.52183">Conscientious objection</a> is another significant barrier. Some doctors are opposed to voluntary assisted dying and even if they practise in a state where they can legally raise it, may choose not to tell their patients about it. This is another reason patients may not know voluntary assisted dying could be a choice for them.</p> <p>It’s important to note our study was only done in Queensland, so we can’t be confident the findings represent the wider Australian population. But given these barriers to knowing about voluntary assisted dying, it’s reasonable to anticipate similar trends in other states.</p> <h2>A national challenge</h2> <p>Raising community awareness of voluntary assisted dying is a challenge around the country. Voluntary assisted dying oversight boards from five states (<a href="https://www.health.qld.gov.au/__data/assets/pdf_file/0019/1362124/vad-annual-report-2023-24.pdf">Queensland</a>, <a href="https://www.health.tas.gov.au/sites/default/files/2024-09/voluntary_assisted_dying_annual_report_2023-24.pdf">Tasmania</a>, <a href="https://www.health.vic.gov.au/sites/default/files/2024-09/voluntary-assisted-dying-review-board_annual-report-2023-24.pdf">Victoria</a>, <a href="https://www.health.wa.gov.au/%7E/media/Corp/Documents/Health-for/Voluntary-assisted-dying/VAD-Board-Annual-Report-2023-24.pdf">Western Australia</a> and <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/73a3fd16-46c4-4ad4-bd82-7a03a924c1bc/VAD+Review+Board+Annual+Report+2023-2024+-+FINAL.pdf?MOD=AJPERES&amp;CACHEID=ROOTWORKSPACE-73a3fd16-46c4-4ad4-bd82-7a03a924c1bc-pdMyZ1p">South Australia</a>) have all discussed this issue in their most recent annual reports.</p> <p>In addition, Western Australia recently reviewed its voluntary assisted dying laws, identifying lack of community knowledge as a problem. The <a href="https://www.parliament.wa.gov.au/publications/tabledpapers.nsf/displaypaper/4113439a2331593cd11da0ae48258be300355868/%24file/voluntary+assisted+dying+act+2019+final+report.pdf">review called for a strategy</a> to fix this.</p> <p>We see this challenge as one of “voluntary assisted dying literacy”. Greater voluntary assisted dying literacy will enable members of the public to know the options available to them, and how to make the choices they want.</p> <h2>What can we do about this?</h2> <p>We need community awareness initiatives to increase knowledge that voluntary assisted dying is legal and ensure people know where to find information about this option. Information about voluntary assisted dying is already available from all <a href="https://www.health.qld.gov.au/clinical-practice/guidelines-procedures/voluntary-assisted-dying">state government health departments</a>, but more action is needed to ensure it reaches more people.</p> <p>Respondents in our survey suggested using social media campaigns, advertising, and sharing information through Centrelink, health clinics and other trusted community channels.</p> <p>We also propose targeted information for particular patient groups who may be eligible for voluntary assisted dying, such as people with cancer or neurodegenerative diseases. This means they will know voluntary assisted dying may be one of the treatment options available to them, and how to navigate the process should they wish to.</p> <p>These initiatives would need to be designed sensitively with a focus on providing information to avoid any perception that people could feel induced or directed to access voluntary assisted dying.</p> <p>Training for health practitioners is also important. This is particularly needed for GPs and specialists working in end-of-life care. Training will support health practitioners to facilitate informed discussions with patients and families.</p> <p>Strong community support was a <a href="https://www.parliament.vic.gov.au/4af889/contentassets/1fa966ea0b6c4034a82bca04f57a19b9/lsic_58-05_text_web.pdf">key argument</a> in legalising voluntary assisted dying in Australia. The public wanted this as an end-of-life choice. But that choice is only a real one if people know it exists.</p> <p><em>Our online resource <a href="https://end-of-life.qut.edu.au/assisteddying">End of Life Law in Australia</a> has more information about voluntary assisted dying and contact points for accessing it in each state.</em><!-- Below is The Conversation's page counter tag.

How do mosquito repellents work? A chemistry expert explains

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>It’s summertime, and for many of us that means plenty of time outside – and, unfortunately, mosquitoes.</p> <p>The combination of the <a href="https://theconversation.com/why-your-summer-might-be-full-of-mosquitoes-according-to-a-scientist-98369">increase in temperature and plenty of water</a> is ideal for these blood-sucking insects to make their presence felt.</p> <p>In the best-case scenario, they are a pest, delivering a highly unpleasant sting. At the other end of the spectrum, they are vectors for diseases responsible for <a href="https://www.cdc.gov/global-health/impact/fighting-the-worlds-deadliest-animal.html">more human fatalities than any other animal on Earth</a>.</p> <p>To keep them at bay, many of us will reach for the bottle of insect repellent or citronella candles in order to avoid the bite and incessant itching that comes with it. But how do these repellents actually work?</p> <h2>A complex interplay</h2> <p><a href="https://www.mcgill.ca/oss/article/health-technology/why-mosquitos-bite-you-and-how-make-them-stop">A great deal</a> of research has gone into understanding how and why female mosquitoes – they are the ones that bite us – are attracted to people.</p> <p>There is evidence showing they are attracted to the <a href="https://www.nih.gov/news-events/nih-research-matters/how-mosquitoes-detect-people">carbon dioxide</a> we exhale, lactic acid found in our sweat, and a variety of other <a href="https://pubmed.ncbi.nlm.nih.gov/24315103/">skin odours</a> and <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6482070/">volatile compounds</a> we give off. The interplay between all these factors is quite <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8906108/">complex</a>.</p> <p>To ward off mosquitoes, physical barriers such as netting make for the best protection. However, while you might put netting around a backdoor patio and barbecue, doing this for any large space is simply not practical.</p> <p>This is where repellents come in.</p> <h2>DEETerrent</h2> <p>There are a variety of mosquito repellents available.</p> <p>The most tried-and-true products are based on a substance called N,N-diethyl-meta-toluamide, more commonly referred to as DEET.</p> <p>This molecule has been commercially available since 1957, <a href="https://www.usda.gov/media/blog/2018/05/17/protecting-military-flying-foes">after the United States military discovered</a> it was an effective insect repellent.</p> <p>DEET is often used as a <a href="https://www.consumerreports.org/health/insect-repellent/how-safe-is-deet-insect-repellent-safety-a4952100929/">point of comparison</a> for <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">studies</a> investigating alternatives. <a href="https://scijournals.onlinelibrary.wiley.com/doi/full/10.1002/ps.5476?casa_token=prUg_pX7fjAAAAAA%3AuEKT5PGXWU1mO4fakwQ9NSEY-0uVYBEz25zWxXjMOp5AxX5UFWENJc1UF_JdsKA45x3sSHpmJSLJSwM">Studies show that</a>, provided they are used according to direction, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4041896/">DEET products are safe and effective</a>.</p> <p>For example, it is recommended that when required, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9458079/">sunscreen is applied</a> before the repellent. DEET products are not recommended for infants.</p> <p>The exact mechanism by which DEET repels mosquitoes and other insects is <a href="https://www.tandfonline.com/doi/full/10.1080/19336934.2015.1079360#d1e132">still explored</a> <a href="https://link.springer.com/article/10.1007/s13258-020-00991-z">today</a>.</p> <p>Many studies link its success to mosquitoes having receptors that sense the presence of DEET, deterring them from closely approaching our skin. Some investigations suggest that when DEET is detected, it <a href="https://pubmed.ncbi.nlm.nih.gov/18339904/">inhibits mosquitoes’ attraction</a> to us, while others show evidence that mosquitoes “<a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2518096/pdf/zpq13598.pdf">smell and avoid</a>” DEET.</p> <p>There are also numerous reports demonstrating mosquitoes don’t bite when they <a href="https://www.cell.com/current-biology/pdfExtended/S0960-9822(19)30402-6">land on</a> DEET-treated skin. This is because DEET acts as a contact-based repellent and conveys a chemical message to mosquitoes to leave. <a href="https://www.tandfonline.com/doi/full/10.1080/19336934.2015.1079360">Studies</a> <a href="https://www.cell.com/current-biology/pdfExtended/S0960-9822(19)30402-6">suggest</a> that DEET likely works through a combination of the processes described here.</p> <h2>Effective alternatives</h2> <p>Another more recent family of mosquito repellent products rely on an active ingredient called picaridin (or icaridin).</p> <p>The current consensus is that picaridin products are safe, and highly effective. For many, they are considered appealing as they <a href="https://www.sciencedirect.com/science/article/pii/S0190962207014673?casa_token=zzPMhkW9QtIAAAAA:Euk6hjWnuiem6OAq020Xv0Pu70K7LfN_siLGcK1DIyOZn-mbH7U9tKK115rAK0rYbWQ2oaMGfg#bib49">don’t have as strong a scent</a> as DEET.</p> <p>Picaridin products have been reported to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">equally effective</a> as DEET, or in some cases, even <a href="https://academic.oup.com/jtm/article/25/suppl_1/S10/4990399">slightly superior</a>, though the outcome depends on their concentration too.</p> <p>The other repellent regularly reported as being effective is para-menthane-3,8-diol (PMD).</p> <p>This is produced by chemical treatment of <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">oil of lemon eucalyptus</a>.</p> <p>Untreated, this oil isn’t effective at repelling mosquitoes. However, <a href="https://onlinelibrary.wiley.com/doi/10.1002/(SICI)1099-1573(199606)10:4%3C313::AID-PTR854%3E3.0.CO;2-O">several</a> <a href="https://journals.sagepub.com/doi/full/10.1016/j.wem.2015.11.007">studies</a> have shown that PMD is an effective mosquito repellent.</p> <p>The ability of these repellents to deter mosquitoes is <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">dose</a> <a href="https://academic.oup.com/jtm/article/25/suppl_1/S10/4990399">dependent</a>.</p> <p>In all cases, it’s important that an appropriate dose is applied, with re-application sometimes required to keep protection to a maximum. The performance of these products varies according to many other variables too, including <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4270489/">the species of mosquito</a>.</p> <h2>What about citronella?</h2> <p>Citronella products, including candles and topical formulations, are popular choices for keeping mosquitoes away.</p> <p>However, in systematic testing, these <a href="https://onlinelibrary.wiley.com/doi/10.1155/2015/361021">have been shown</a> to be <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">far less effective</a> than DEET.</p> <p>Studies have also shown that <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">citronella candles don’t</a> <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4617422/">fend off mosquitoes</a> <a href="https://pubmed.ncbi.nlm.nih.gov/8827606/">as much</a> as you might like.</p> <p>There are many other repellent products on the market.</p> <p>Given the widespread interest in preventing mosquito bites, natural remedies abound. It’s important to recognise that natural <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">isn’t necessarily more effective</a> and it <a href="https://theconversation.com/what-does-a-chemical-do-addressing-misconceptions-about-chemistry-104085">isn’t necessarily safer</a>.</p> <p>In <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa011699">most reported studies</a>, DEET and picaridin are reported as having the greatest duration of protection (of the order of hours) and greatest effect on the mosquitoes. They are more thoroughly tested than many alternatives.</p> <p>When others are tested, they are often found wanting.</p> <p>One study described sound-based devices as being the repellent equivalent of <a href="https://academic.oup.com/jinsectscience/article/17/1/24/2996380?login=false">snake oil</a>. And although repellent bracelets contain working ingredients, they are largely ineffective in that form. This is because of insufficient concentrations of the active ingredient being “emitted”.</p> <p>When it comes to preventing disease transmission via mosquitoes, the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4041896/">benefits</a> of the proven repellents far outweigh the risks.<!-- Below is The Conversation's page counter tag.

Top 10 must-do activities around the world in 2025

<p>Global travel brand <em>Time Out</em> has revealed their annual list of the best activities around the world. </p> <p>From a canoe trip in Australia to wildlife encounters in Singapore, here are the top 10 must-do activities and experiences around the world. </p> <p><strong>10. Take a micro cruise through the Arctic. </strong></p> <p>This year, Micro-cruise specialist Secret Atlas will be taking 12 passengers at a time through the Arctic, for a more "intimate, once-in-a-lifetime, eco-conscious trip". </p> <p>The cruise will take guests on a wildlife-spotting journey through Svalbard's lesser-known northern reaches, while the other cruise will sail past the icebergs in Northeast Greenland, including a visit to one of the most remote towns on earth. </p> <p>These trips, however, aren't cheap with prices starting at £15,500 (around AUD $30,500) for two weeks.</p> <p><strong>9. Explore the cross-border towns of Gorizia, Italy, and Nova Gorica, Slovenia</strong></p> <p>These three towns make up 2025's European Capital of Culture, with over 400 events to be held throughout the year, including a piano performance on a 200m-high bridge, as well as a food and wine event called Tastes Without Borders.</p> <p><strong>8. Go on a wildlife-spotting adventure in Singapore's new Rainforest Park </strong></p> <p>The Mandai Wildlife Reserve is opening its fifth zoological park, Rainforest Wild Asia, this year, with 10 different zones, as well as 29 different species of animals, perfect for a family outing. </p> <p><strong>7. Discover Vietnam by a vintage steam train</strong></p> <p>Time Out explained that two of the "beautifully restored vintage trains" date all the way back to the 60s, and will take passengers between "the central city of Da Nang and the former royal capital of Hue."</p> <p><strong>6. Visit the Musée Granet celebrating the father of post-impressionism</strong></p> <p>Aix-en-Provence in France is celebrating the life of post-impressionist painter Paul Cezanne in his hometown, with the exhibition displaying almost 100 of Cèzanne’s works, as well as tours around the artist’s childhood home, former estate and art studio. </p> <p><strong>5. Visit the long-awaited Harlem's Studio Museum, New York</strong></p> <p>The Studio Museum in Harlem, New York, was first opened 56 years ago, with an archive of almost 9,000 pieces from all kinds of creators. It was closed for construction almost seven years ago and will finally re-open in autumn. </p> <p><strong>4. Fly directly to Greenland </strong></p> <p>The grand opening of their brand-new international airport will make this stunning location <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> </span><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">more accessible</span><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> for travellers wanting to view the Northern Lights and all of the territory's natural wonders. </span></p> <p><strong><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">3.

Why do some people’s hair and nails grow quicker than mine?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-moscova-310728">Michelle Moscova</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Throughout recorded history, our hair and nails played an important role in signifying who <a href="https://www.psychiatrictimes.com/view/gender-culture-and-social-constructs-in-body-focused-repetitive-behaviors">we are and our social status</a>. You could say, they separate the caveman from businessman.</p> <p>It was no surprise then that many of us found a new level of appreciation for our hairdressers and nail artists during the COVID lockdowns. Even Taylor Swift reported <a href="https://abcnews.go.com/GMA/Culture/taylor-swift-reveals-shes-cutting-hair-covid-19/story?id=74757540&amp;t">she cut her own hair during lockdown</a>.</p> <p>So, what would happen if all this hair and nail grooming got too much for us and we decided to give it all up. Would our hair and nails just keep on growing?</p> <p>The answer is yes. The hair on our head grows, on average, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9917549/">1 centimeter per month</a>, while our fingernails grow an average of just <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11436330/">over 3 millimetres</a>.</p> <p>When left unchecked, our hair and nails can grow to impressive lengths. Aliia Nasyrova, known as the Ukrainian Rapunzel, holds the world record for the longest locks on a living woman, which measure an <a href="https://www.youtube.com/watch?v=1TdlEIQdVwo&amp;t=81s">impressive 257.33 cm</a>.</p> <p>When it comes to record-breaking fingernails, Diana Armstrong from the United States holds that record <a href="https://www.youtube.com/watch?v=nwql937j-7Q">at 1,306.58 cm</a>.</p> <p>Most of us, however, get regular haircuts and trim our nails – some with greater frequency than others. So why do some people’s hair and nails grow more quickly?</p> <h2>Remind me, what are they made out of?</h2> <p>Hair and nails are made mostly from keratin. Both grow from matrix cells below the skin and grow through different patterns of cell division.</p> <p>Nails grow steadily from the matrix cells, which sit under the skin at the base of the nail. These cells divide, pushing the older cells forward. As they grow, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5383514/">the new cells slide</a> along the nail bed – the flat area under the fingernail which looks pink because of its rich blood supply.</p> <p>A hair also starts growing from the matrix cells, eventually forming the visible part of the hair – the shaft. The hair shaft grows from a root that sits under the skin and is wrapped in a sac known as the hair follicle.</p> <p>This sac has a nerve supply (which is why it hurts to pull out a hair), oil-producing glands that lubricate the hair and a tiny muscle that <a href="https://www.ncbi.nlm.nih.gov/books/NBK546248/">makes your hair stand up</a> when it’s cold.</p> <p>At the follicle’s base is the hair bulb, which contains the all-important hair papilla that supplies blood to the follicle.</p> <p>Matrix cells near the papilla divide to produce new hair cells, which then harden and form the hair shaft. As the new hair cells are made, the hair is pushed up above the skin <a href="https://www.jidonline.org/article/S0022-202X(15)41553-2/fulltext">and the hair grows</a>.</p> <p>But the papilla also plays an integral part in regulating hair growth cycles, as it sends signals to the stem cells to move to the base of the follicle and form a hair matrix.

Younger people generally have faster growth rates because of the slowing metabolism and cell division that comes with ageing.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">Hormonal changes</a> can have an impact. Pregnancy often <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">accelerates</a> hair and nail growth rates, while menopause and high levels of the stress hormone cortisol can <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7432488/">slow growth rates</a>.</p> <p>Nutrition also changes <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">nail</a> strength and growth rate. While hair and nails are made mostly of keratin, they also contain water, fats and various minerals. As hair and nails keep growing, these minerals need to be replaced.</p> <p>That’s why a balanced diet that includes sufficient nutrients to support your hair and nails is essential for maintaining their health.</p> <p>Nutrient deficiencies may contribute to hair loss and nail breakage by disrupting their growth cycle or weakening their structure. Iron and zinc deficiencies, for example, have both been linked to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6380979/">hair loss</a> and <a href="https://ijdvl.com/nails-in-nutritional-deficiencies/?t">brittle nails</a>.</p> <p>This may explain why thick hair and strong, well-groomed nails have long been associated with perception of good health and high status.</p> <p>However, not all perceptions are true.</p> <h2>No, hair and nails don’t grow after death</h2> <p>A persistent myth that may relate to <a href="https://www.britannica.com/topic/vampire">the legends of vampires</a> is that hair and nails continue to grow after we die.</p> <p>In reality, they only <em>appear</em> to do so. As the body dehydrates after death, the skin shrinks, making hair and nails <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2151163/">seem longer</a>.</p> <p>Morticians are well aware of this phenomenon and some <a href="https://www.adomonline.com/mortuary-man-reveals-how-he-handles-nails-of-the-dead/?t">inject tissue filler</a> into the deceased’s fingertips to minimise this effect.</p> <p>So, it seems that living or dead, there is no escape from the never-ending task of caring for our hair and nails.<!-- Below is The Conversation's page counter tag.

Do natural fabrics really keep us cooler in summer? Here’s the science

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen.</p> <p>But why are natural fabrics like these so much better at keeping us cool when the weather is hot?</p> <p>Here’s what the science says.</p> <h2>Natural fabrics and sweat: a match made in heaven</h2> <p>In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down.</p> <p>In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible.</p> <p>Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk.</p> <p>The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin.</p> <p>Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water.</p> <p>So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily.</p> <p>This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures.</p> <p>One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look).</p> <p>And on a really hot, sweaty day, natural fabrics can get heavy and wet.</p> <p>Animal fibres are basically proteins, and their properties vary depending on the source.</p> <p>Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away.</p> <p>On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather.</p> <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> <p>Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less.</p> <p>Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals.</p> <p>Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier.</p> <p>Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily.</p> <p>They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid.</p> <p>However, some synthetic fabrics used in certain types of active wear can wick sweat away from body.</p> <p>And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon.</p> <h2>Fabric weave makes a difference, too</h2> <p>The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler.</p> <p>There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal.</p> <p>Another factor affecting breathability and comfort of clothing is the way the fabrics are woven.</p> <p>Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool.</p> <p>For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is.</p> <p>The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance.</p> <p>Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics.</p> <p>Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant.</p> <p>Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<!-- Below is The Conversation's page counter tag.
