Mother arrested after two boys found dead in Blue Mountains home

A mother has been arrested after the tragic discovery of her two sons, aged nine and 11, dead at their home in the Blue Mountains, New South Wales. The boys, Russell and Ben, were found by their father at the family's home in Faulconbridge shortly before 12:40pm. Their mother, Trish Smith, 42, was also found at the scene with several self-inflicted injuries. She has been taken to Westmead Hospital and is in a stable condition. No charges have been laid so far. Superintendent John Nelson of the Blue Mountains police confirmed that Mr Smith, the father, discovered the bodies and contacted authorities. "The father is helping us with inquiries, and he was the one who contacted police... all avenues are open for investigation," Nelson stated. While the police have not confirmed whether a weapon was involved, they are working to understand the sequence of events leading to the boys' deaths. The family, who had no prior history of domestic violence and minimal contact with the police, has left the community in shock. Superintendent Nelson said that the investigation is still in its early stages, and no speculation will be made at this time. The boys had attended school on Monday with no apparent issues, and authorities are now trying to trace their movements on Tuesday to piece together what might have happened. The nearby Springwood High School was involved in the emergency response as its oval was used as a helipad for medical evacuations. Homicide detectives from the State Crime Command have been assigned to the case, and police are continuing to speak with neighbours to uncover any possible motives. Blue Mountains Mayor Mark Greenhill expressed the community’s grief in a statement: "Our community has lost two precious souls in the most awful circumstances. Now is a time to come together and remember these two beautiful children." NSW Police Commissioner Karen Webb acknowledged the profound emotional toll the incident has had on law enforcement officers. "I think the older and more experience you get in this job, things like this still cut to the core. It’s a tragic situation," she said. Authorities have confirmed that no one else is being sought in connection with the deaths, and there is no ongoing threat to the community. The investigation continues as police work to understand the full circumstances surrounding this heartbreaking incident. Need to talk to someone? Don't go it alone.

Supreme Court Justice killed just three weeks after retiring

Former South Australian Supreme Court Justice Malcolm Blue has tragically died, just three weeks after retiring. The 70-year-old had been looking forward to spending quality time with his friends and family after retiring, when he was involved in a tractor accident at a vineyard in Willunga South on Saturday morning. South Australian Police were called to the scene after the accident, where police said he died at the scene from his injuries. After his 13-year role as a Supreme Court judge where he earned the respect of politicians and legal professionals, Blue retired in August, as his family said he had been looking forward to spending more time with his family during his retirement. “We are devastated by Malcolm’s loss. He was a much-loved and loving father, partner and brother, and cherished his family,” his family said in a statement <a href="https://www.adelaidenow.com.au/news/south-australia/justice-malcolm-blue-remembered-as-a-great-south-australian-after-death-in-farming-tragedy/news-story/49330193603000f8a0cbf7933b5b7eea?amp" target="_blank" rel="noopener" data-link-type="article-inline">to News Corp.</a> “Malcolm was always kind, funny, smart and wonderfully supportive for family, friends and legal colleagues. He was both gentle and brilliant and will be missed terribly." “Having achieved so much during a long and distinguished legal career, Malcolm was looking forward to spending more time with his family on the property." “Malcolm will be deeply missed by his partner Angela, daughters Charlotte, Victoria and Alex, three sisters, along with his extended family, many friends, and colleagues in the legal fraternity.” SA Premier Peter Malinauskas praised Blue’s service to the state at a press conference on Sunday. “Mr Blue was a great South Australian who served his community exceptionally well over a very long period of time,” Malinauskas said. “I’m sure that South Australia will appropriately honour him as someone who’s made a major contribution.” Chief Justice of South Australia Chris Kourakis said Blue’s death was felt across Australia’s judiciary and legal profession, saying, “Justice Blue was a pre-eminent intellect and jurist who selflessly devoted his energy to the work of the court and making justice more accessible to the people of South Australia.” Image credits: 7News

Caring

Yes, blue light from your phone can harm your skin. A dermatologist explains

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you. Now social media has blue light from our devices in its sights. So can scrolling on our phones really damage your skin? And will applying creams or lotions help? Here’s what the evidence says and what we should really be focusing on. <h2>Remind me, what actually is blue light?</h2> Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels <a href="https://melasmaclinic.com.au/wp-content/uploads/2024/01/Melasma-LEDS.pdf">100-1,000 times</a> lower. Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including <a href="https://theconversation.com/do-blue-light-glasses-really-work-can-they-reduce-eye-strain-or-help-me-sleep-213145">on our eyes and sleep</a>. Now, we’re learning more about the impact of blue light on our skin. <h2>How does blue light affect the skin?</h2> The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings. 1. Blue light can increase pigmentation <a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&login=false">Studies</a> <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/srt.13401">suggest</a> exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour. So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin. 2. Blue light can give you wrinkles Some research <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280109/">suggests</a> blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles. A laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/29399830/">study suggests</a> this can happen if you hold your device one centimetre from your skin for as little as an hour. However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure <a href="https://en.wikipedia.org/wiki/Inverse-square_law">100-fold</a>. So this is much less likely to be significant. 3. Blue light can disrupt your sleep, affecting your skin If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation. We know blue light is particularly good at <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01413.2009?rss=1">suppressing</a> production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle. By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the <a href="https://www.tandfonline.com/doi/abs/10.1080/07420528.2023.2173606">quality of your sleep</a>. The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state. Long-term sleep problems can also <a href="https://academic.oup.com/ced/article-abstract/40/1/17/6621145?login=false">worsen</a> existing skin conditions, such as acne, eczema and rosacea. Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness. <h2>Can skincare protect me?</h2> The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses. From a practical perspective, probably only those with the more troublesome hyperpigmentation known as <a href="https://dermnetnz.org/topics/melasma">melasma</a> need to be concerned about blue light from devices. This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective. But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine. <h2>What can I do to minimise blue light then?</h2> Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep: <ul> <li> use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening </li> <li> minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin </li> <li> hold your phone or device away from your skin to minimise exposure to blue light </li> <li> use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light. </li> </ul> <h2>In a nutshell</h2> Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing. While skincare to protect against blue light shows promise, more testing is needed to determine if it works. For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233335/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan. f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>. But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge. Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community. This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California. Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>. Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>. However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life. <h2>Is the secret in our diet?</h2> When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones. For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease. In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age. Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity. But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses. Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>. Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity. Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing. There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life. Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing. Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Pathetic" fine for killer of beloved 40-year-old blue groper

In a shocking act of disregard for both marine life and the law, a 26-year-old individual has plunged a spear into the heart of Sydney's Cronulla community by illegally spearing and killing the beloved blue groper known as Gus. Blue gropers, revered for their non-aggressive nature and inquisitive demeanour, have been the official fish of New South Wales since 1996, enjoying legal protection against spearfishing and commercial exploitation. After visiting and entertaining locals in the area for over 40 years, Gus, affectionately named by the community, met a tragic end at Old Park in Cronulla, a well-signed no-spearfishing zone. The incident has left the local community seething with anger and grief, prompting demands for harsher penalties and increased community education. A local Facebook post on the incident quickly garnered more than 100 comments and 500 reactions, reflecting the collective outrage of concerned locals. One individual expressed their frustration, saying, "Omg what an a**hole! I've been trying to find that groper for ages, and now I'll never get to see him. I hope this guy gets a massive fine." Witnesses to the distressing incident, including Tenielle Piek, reported the callousness of the spearfisherman to <a href="https://www.news.com.au/technology/environment/outrage-over-fishermans-pathetic-punishment-for-killing-iconic-blue-groper-in-cronulla/news-story/7dec503e9b95ec1fd8d7e7b0f8438036" target="_blank" rel="noopener">news.com.au</a>, who proudly displayed the lifeless groper. Piek lamented the loss of the "Labrador of the Sea" and the vulnerability of these tame and curious creatures to spearfishing. She fears that future generations may be deprived of the opportunity to experience these beautiful creatures in their natural habitat along the shores of Cronulla. Despite the gravity of the crime, the spearfisherman was initially handed a meagre fine of $500, sparking outrage among locals who believed the punishment to be woefully inadequate. NSW Fisheries then tacked on an additional $300, and while the culprit displayed remorse during the interview with fisheries officers and was a first-time offender, the community clearly still feels shortchanged by the leniency of the penalty. A spokesperson from the Department of Primary Industries claimed that the individual was provided with education and awareness material to understand the rules of spearfishing. However, the paltry $300 fine out of a potential $11,000 seems insufficient to deter future acts of this nature. As the investigation appears to conclude, the Cronulla community remains on edge, grappling with the inadequacy of the penalties issued. The tragic fate of Gus demands justice and a resolute commitment to preserving the delicate marine ecosystem. Anything less than a substantial deterrent risks further harm to these innocent creatures and the cherished natural beauty of Cronulla's shores. Images: Facebook

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

Or could they do you harm? We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found. <h2>What are they?</h2> Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes. Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light. A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>. There’s often an added cost, which depends on the specific product. So, is the extra expense worth it? <h2>Blue light is all around us</h2> Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light. The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption>Screens emit blue light.

So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies. We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults. <h2>Do they reduce eye strain?</h2> We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use. This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days. <h2>Do they help you sleep?</h2> Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed. These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population. <h2>Do they boost your eye health?</h2> We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision). None of the studies evaluated this. <h2>Could they do harm? How about causing headaches?</h2> We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses. Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects. <h2>What about other benefits or harms?</h2> There are some important general considerations when interpreting our findings. First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health. Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children. Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these. <h2>In a nutshell</h2> Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina. High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status. If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213145/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, Associate Professor in Optometry and Vision Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to beat the retirement blues

When people plan their retirement they don’t usually expect Post retiring depression (PRD). This kind of depression usually stems from dashed expectations, financial trouble or feeling lost and lonely. That’s why we’ve got four top tips to avoid PRD and enjoy your free time. 1. Plan it out Know what you want to do, not what you think you should be doing. Don’t hold back in indulging yourself, travelling the world, volunteering abroad – the temporary discomfort of not knowing is better than realising when it’s too late that you never completed your bucket list. 2. Routine A sudden lack of structure can become exhausting or at least unsettling. Schedule activities such as exercise, housework, errands, and social time. Then let the day flow from there. 3. Keep active There is a lot of research to show that the people who cope best with retirement are those who stay active and involved. This might include: <ul> <li>Developing an old hobby or starting a new one. </li> <li>Staying physically active, through walking, swimming, gym or sport. Make sure your exercise routine is appropriate for your physical capacities and limitations. </li> <li>Volunteering with a charity or church group. </li> <li>Working part-time. </li> <li>Studying a course.</li> </ul> 4. Stay in touch Loneliness and isolation can be easily avoided, so don’t fall into the trap of feeling alone. Make the effort to stay in contact with family and friends. Offer to babysit your grandchildren. Check out local community centres for upcoming activities you might enjoy. Even if you're not sure try something new, you might surprise yourself! Images: Getty

"I fell for it!": Boys in blue crash gender reveal party

One Sydney couple have taken their friends and family by surprise with their high-stakes gender reveal, where the father-to-be was apparently put under arrest by two police officers. Mina Ibrahim revealed their elaborate prank with a video posted to his TikTok account. Mina’s video begins with footage of the moment of his ‘arrest’, before it cuts to the TikToker at a later date, explaining that “that’s me being arrested at my baby’s gender reveal.” He goes on to share the full video, and a promise that the ending will answer any questions his viewers may have. In the clip, the parents-to-be can be seen talking to two uniformed NSW ‘police officers’, guests all around them, with Mina asking for onlookers to get their phones out. He then pushes one of the officers, telling them to leave, and both grab him before attempting to handcuff him, while his pregnant partner attempts to intervene. As family members rush to assist, one of the officers calls for everyone to calm down, then delivers news that takes them all by surprise - and delight - by telling them, “it’s a baby girl.” “So it was the cops who announced to everyone that I was having a baby girl,” present-day Mina informed his audience, before noting that there was a fake balloon inside to throw their guests off the surprise scent. <div class="mol-embed" style="font-size: 16px; margin: 0px 0px 8px; padding: 0px; min-height: 1px; letter-spacing: -0.16px; text-align: center; font-family: graphik, Arial, sans-serif; background-color: #ffffff;"> <blockquote id="v34606683345148116" class="tiktok-embed" style="margin: 18px auto; padding: 0px; min-height: 1px; letter-spacing: -0.01em; position: relative; width: 605px; box-sizing: border-box; line-height: 1.15; overflow: hidden; text-size-adjust: 100%; font-family: proxima-regular, PingFangSC, sans-serif; max-width: 605px; min-width: 325px;" cite="https://www.tiktok.com/@mina.ibs/video/7232964823296773383" data-video-id="7232964823296773383" data-embed-from="oembed"><iframe style="letter-spacing: -0.01em; border-width: initial; border-style: none; width: 605px; height: 735px; display: block; visibility: unset; max-height: 735px;" src="https://www.tiktok.com/embed/v2/7232964823296773383?lang=en-GB&referrer=https%3A%2F%2Fwww.dailymail.co.uk%2Fnews%2Farticle-12082153%2FGender-reveal-party-prank-sees-cops-arrest-father-be.html&embedFrom=oembed" name="__tt_embed__v34606683345148116" sandbox="allow-popups allow-popups-to-escape-sandbox allow-scripts allow-top-navigation allow-same-origin"></iframe></blockquote> </div> The prank attracted thousands of views online, with many flocking to his comments section to share their congratulations with the parents-to-be. Others, while thrilled for them and their happy news, were open about their concern, having fallen for the trick right along with the couple’s loved ones. “I fell for it and I was worried for your wife!!!,” one confessed. “I was freaking out hahahah you got me”. “I was worried too haha … you scared me,” another said. “Omygosh! I was ready to sue them coppas with you!” came one response, “but congratsss! What a way to reveal!” One other simply wanted to know if the entire situation was even allowed, believing that impersonating the police may not be. And another had simply been suspicious from the very start, noting “Broooo the whole time I was like … something ain’t right! He’s not carrying his gun”. Images: TikTok

Aussie author of "Puberty Blues" dies at 64

Gabrielle Carey, co-author of the iconic novel Puberty Blues, has passed away at 64. The news was reportedly broken by Carey’s old friend and co-writer Kathy Lette, who was the other half of the creative powerhouse that brought Puberty Blues to life. In a post to social media, Lette shared a throwback picture of the pair in their younger years, and wrote, “I’m deeply saddened by the tragic news about my old friend Gabrielle Carey. “I have such happy memories of our teenage years. They were halcyon, heady days full of love, laughter and adventure. “We made some mischief and broke some barriers by writing Puberty Blues – our raw, earthy take on the brutal treatment of young women in the Australian surfing scene which is sadly, still so relevant. “My heartfelt condolences to her family and friends.” <blockquote class="twitter-tweet"> I’m deeply saddened by the tragic news about my old friend Gabrielle Carey. I have such happy memories of our teenage years. They were halcyon, heady days full of love, laughter and adventure. 1/2 🧵 <a href="https://t.co/2wZZiRf1hd">pic.twitter.com/2wZZiRf1hd</a> — Kathy Lette (@KathyLette) <a href="https://twitter.com/KathyLette/status/1654136967636959234?ref_src=twsrc%5Etfw">May 4, 2023</a></blockquote> The groundbreaking book they penned together, which went on to be adapted as both a movie and a hit TV series, was a candid - then-controversial - story of two teenage girls growing up in Sydney’s Sutherland Shire. It pushed boundaries, captivated young audiences while tackling themes many did not expect for said target audience, and is regarded by many as being the first Australian teenage novel to be written by teens. From Puberty Blues, Carey went on to publish memoirs and nonfiction works, with another of her books - her 1984 Just Us, which covered her relationship with rapist and prisoner Terry Haley, who she married while he was imprisoned - also made into a telemovie in 1986. No suspicious circumstances surrounded her death, according to The Australian, though the tragic news comes just months after she wrote about her father’s suicide in The Sydney Morning Herald. At the time, Carey had revealed she was afraid of reaching 64, as that was when he too had passed on. “It was only decades later, when my father died from suicide on the very day he turned 64, that I became terrified of that number,” she wrote. “If I have inherited my father’s disposition for depression, did that mean I would also end up in an early grave? Carey’s early passing is one that has hit her friends and her fans hard, with many joining Lette in sharing their grief and their condolences on social media. “Farewell dear Gabrielle. You were a sister in the cause of mental illness, its impact & our children. I’m enriched for having known you,” one supporter wrote. “Thank you.” “Writer - Reader - Intellectual - Joycean (fanatical) - Elizabeth von Arnim devotee - Avid Gardener - Rose Petal Jam Maker - Football Follower - Kayaker - Yogi - Joker - Irrepressible Spirit - Hobbit - Underground Writer - My Friend,” friend and fellow writer Yumna Kassab wrote. “I will always miss you.” “So sorry for your loss,” one fan said in response to Lette’s tweet. “You have no idea how much as a girl growing up in a coastal town with a surfing scene I understood Puberty Blues. I saw it every day. You & Gabrielle laid it all bare & made girls stand up for themselves. Thank you”. “My deepest condolences Kathy,” another offered. “The two of you wrote something so treasured by Gen X girls. It was our ‘how to say no guide’. Our Teen handbook. But it still let us live our lives & learn as we went. RIP Gabrielle Carey.” Images: Facebook

Don’t say cheese! Travel destinations where photos are illegal

While many happy travellers love to immortalise their holiday with a collection of photos, there are some places that don’t allow for pics to be taken. In several destinations across the globe, tourists are actually banned from taking selfies and can even get fined for breaking the rules. So before you pull out your camera and strike a pose, you might want to check if what you’re snapping a photo of is legal. Here are just a few places where taking photos isn’t allowed. The Sistine Chapel, Vatican City The use of professional cameras and phones is strictly prohibited in the Sistine Chapel so don't even think about it. According to <a href="https://www.vaticancitytours.it/blog/are-cameras-allowed-in-the-vatican-city/#:~:text=Sistine%20Chapel&text=The%20real%20reason%20for%20the,companies%20to%20fund%20the%20project.">VaticanCityTours,</a> the reason you can't take pictures dates back to 1980 when the chapel was restored due to damage caused by flash photography. Mecca Pilgrimage, Saudi Arabia In Saudi Arabia, it is against the law to take photos of worshippers during Hajj, otherwise known as their pilgrimage to the holy city of Mecca. This is due to it being disrespectful to snap people while they are on their religious journey. The Blue Mosque, Turkey Taking a photo of the outside of the iconic Blue Mosque is totally okay, but snapping any photos of the interior is a big no. Visitors also must follow strict dress codes as well as other rules and regulations. Anne Frank's House, Amsterdam Taking photos or selfies in the House of Anne Frank is not allowed inside the museum due to its serious nature. There is a very sombre mood within the historical house, making it a time for reflection, not for flash photography. Palace of Versailles, France Photos of both the Palace and the surrounding gardens are strictly prohibited for all travellers. This is due to concerns about the preservation of artwork and the safety of visitors. Garoupe Beach, France The famous Garoupe beach in southern France banned holidaymakers from taking selfies during the busy season in the middle of summer. The law was first introduced to stop people from bragging about their holiday and just enjoy the stay rather than show off on social media. Image credits: Getty Images

Hill Street Blues star passes away

Hill Street Blues star Barbara Bosson has passed away aged 83. Bosson, who played Fay Furillo in the American police drama, was a popular TV star in the ‘80s, earning five consecutive Emmy nominations for her role. She was also the ex-wife of TV giant Steven Bohcho, who created Hill Street Blues and several other hit shows at the time. The news of Bosson’s death was shared by her son, Jesse Bohcho, who shared an image of he and his mother when he was a child. "More spirit and zest than you could shake a stick at. When she loved you, you felt it without a doubt. If she didn't, you may well have also known that too. Forever in our hearts. I love you Mama. Barbara "Babs" Bosson Bochco 1939-2023," he captioned the image. Dirty Dancing star Jennifer Grey shared her support, commenting a red heart under Bochco’s Instagram. Bosson was also known for her roles in shows including Murder One, Hooperman and films including Cop Rock and Calendar Girl Murders. Hill Street Blues proved Bosson's main claim to fame, with her leaving the show in 1985 during its sixth season after being fired from the project over creative disagreements. Bosson and Steven Bohcho went on to work together on other projects, including the Rockford Files spin-off Richie Brockelman, Private Eye, Hooperman and the musical Cop Rock. The pair divorced in 1997 but continued to co-parent their son Jesse, who was born in 1975. Steven died in 2018 at the age of 73. Further details of Bosson’s death are yet to be revealed.

Doctors say cheese could be as addictive as drugs

Look, we’ve all be there: you’re enjoying a tasty cheese platter, perhaps with a glass of red, and before you know it, you’ve devoured the entire wheel of camembert. You’re not even sure how it happened; all you know is the cheese was too delicious to stop. But before you berate yourself for your lack of willpower, stop – because it may not be your willpower but that the cheese is simply too addictive. According to Thrillist, Dr Neal Barnard, founder and president of the Physicians Committee for Responsible Medicine, has called cheese “dairy crack” because your brain reacts to a particular protein in it the way it would any other addictive substance. “These protein fragments can attach to the opiate receptors in your brain,” Dr Barnard says. “As the name implies, casomorphins are casein-derived morphine-like compounds.” Cheese also has high fat and salt content – two other things that our brains enjoy. However, lucky for all the cheese lovers out there, even though our brains may react to cheese similarly to morphine, it doesn’t have any brain-destroying compounds as the drug. Image: Getty

Can you freeze cheese?

Dairy products are notoriously fussy when it comes to freezing. But when there’s a great sale at the supermarket, it’s hard to resist the siren call of a big discounted brick of cheese. It doesn’t last forever in the refrigerator, but can you freeze cheese? Yes – sometimes! The general rule of thumb is that freezing cheese will likely change its texture. If you do opt to freeze extra cheese, its best use after thawing is for cooking– the texture change becomes a moot point after it’s all melted. You probably don’t want to freeze the fancy stuff you bought for snacking on with homemade crackers, though. But frozen cheese, once thawed, would be perfect in a cheesy bake or casserole recipe. Can you freeze mozzarella? Blocks of mozzarella or shredded mozzarella are fine to freeze, though they tend to have a crumbly texture after freezing. Just avoid freezing fresh mozzarella, as its high water content has a likelihood of forming ice crystals. Can you freeze cottage cheese? Cottage cheese, along with ricotta cheese, can be frozen. However, upon thawing, both cheeses are likely to have a grainier texture. As with most frozen cheeses, thawed cottage and ricotta cheeses are best used in baked or cooked recipes. Can you freeze cheese slices? Yep! For prepackaged sliced cheese, just pop the package into a freezer bag and place it in the freezer. For deli-sliced cheese, place a piece of parchment paper in between each slice of cheese. Then wrap the cheese in freezer paper, tape shut and place the whole package in a freezer bag or freezer-safe container. Can you freeze shredded cheese? For prepackaged shredded cheese, place the package in a freezer bag before putting it in the freezer. For cheese you shred or grate yourself, place it in a freezer bag and carefully remove as much air as possible from the bag.

Why is cheese so stinky?

For those who partake, cheese can be one of the most delicious, yet sometimes stinky, parts of a good meal. Everything from a charcutier board to a pizza becomes infinitely better with some cheese. But cheese has some deep, dark secrets in its yellow interior – and most of them involve large quantities of mould. <h3>How did we even get cheese in the first place? </h3> Researchers think that we’ve been eating cheese for a very long time. <a href="https://cosmosmagazine.com/history/study-finds-europeans-have-been-eating-cheese-for-at-least-7200-years/">In 2018,</a> archaeologists discovered pieces of ancient pottery in modern day Croatia that had fatty acid residues on it that could have been cheese. The team suggested that these early farmers could have been eating cheese from at least 7,200 years ago. To put that in perspective, that’s at least three thousand years before the first Egyptian dynasty. Unfortunately, scientists don’t know what that sort of cheese would have been like, but the evidence suggests that many early cheeses were like cottage cheese. According <a href="https://www.idfa.org/history-of-cheese" target="_blank" rel="noopener">to the International Dairy Foods Association</a>, cheese could have been an accidental discovery. Rennet – a group of enzymes located in sheep or cow stomachs – cause milk to curdle. If a cow or sheep’s stomach was used for milk transportation, the rennet will start the process of cheese-making and create curds and whey. This dairy-like substance is heading in the direction of cheese. <h3>How do we make cheese?</h3> Today’s cheese making is pretty similar to how they did it back then – but with a lot more microbes added to the process. Instead of rennet to curdle the milk, today many producers use chymosin – which is the chief enzyme in rennet. If you genetically engineer the yeast by inserting rennet genes from animals into the yeast genome they’ll happily pump out chymosin for all our cheese making needs. But be warned, you’ll need vats of the stuff. Whey is not really used in cheese making, but the curds are where the cheese process really starts. These blobs of a white, kind of squeaky substance is then processed into different forms to make different cheeses. Mozzarella is stretched and kneaded to its dough-like texture, while cheddar undergoes ‘cheddaring’ – a process where curds are stacked on top of each other to push out moisture and create a harder, denser cheese. For other cheeses, there’s a secret ingredient missing – microbes. Many different varieties need to go through a process of ‘ripening’, where microbes, like fungi and bacteria, are added to the base cheese and then left to sit. Brie and camembert get sprayed with <a href="https://en.wikipedia.org/wiki/Penicillium_camemberti" target="_blank" rel="noopener">Penicillium camemberti</a> mould and left from four to five weeks to get their white outside and soft squishy interior. Blue cheese, on the other hand is injected with spores from Penicillium roqueforti to be able to create those blue veins of mould. But these moulds all pale in comparison to a particularly stinky type of bacteria called <a href="https://en.wikipedia.org/wiki/Brevibacterium_linens" target="_blank" rel="noopener">Brevibacterium linens</a>. This bacterium is used to ferment particularly funky cheeses like Munster, but it’s also the bacteria which causes human foot odour. Just think about that next time you’re having some cheese on crackers! <h2>Cheese dreams?</h2> It’s a commonly-held belief that eating cheese can give you nightmares. And in fact, <a href="https://cosmosmagazine.com/science/biology/explainer-can-cheese-make-you-have-weird-dreams/">scientists have put this to the test.</a> A 2005 study – conducted by the British Cheese Board – asked participants to eat 20 grams of cheese half an hour before going to bed every night for a week. When they woke up, they immediately wrote down any dreams. Participant were assigned a type of cheese: stilton, cheddar, red Leicester, British brie, Lancashire and Cheshire. None of the 200 volunteers reported having nightmares, but delightfully, 83 per cent of the participants that ate red Leicester had pleasant dreams. Cheddar, on the other hand, led to dreams about celebrities, while Cheshire led to no dreams more than half of the time. Although this study is heaps of fun, we can’t comment on the scientific rigor of the British Cheese Board, so you should probably take the story with a grain of salt. If you want even more cheesy facts, find out about raw cheese, and endure plenty of cheese puns, keep an ear out for a whole episode on cheese for the ‘Huh? Science Explained’ podcast on the <a href="https://www.listnr.com/podcasts/huh-science-explained" target="_blank" rel="noopener">LISTNR app</a>, or anywhere you get your podcasts.
