I spy with my little eye: 3 unusual Australian plant ecosystems to spot on your next roadtrip

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/gregory-moore-1779">Gregory Moore</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>When the growing gets tough, the tough trees and shrubs get growing.</p> <p>Australia’s environment is brutal. Its ancient, low-nutrient soils and generally low rainfall make it a hard place for plants to grow. Despite this, the continent is filled with wonderfully diverse plant ecosystems.</p> <p>If you don’t know what you’re looking for, it can be easy to miss these seemingly unremarkable species. So, here are three little-known Australian plant species and ecosystems to look out for during your next roadtrip.</p> <h2>1. Cycads and eucalypts</h2> <p>If you are driving a coastal route along southern New South Wales, keep an eye out for the stunning combination of burrawang cycads (<em>Macrozamia communis</em>) and spotted gum (<em>Corymbia maculata</em>). These species live in harmony along the <a href="https://www.botanicgardens.org.au/our-science/our-collections/plant-families/cycads#:%7E:text=Meet%20one%20of%20the%20world's%20most%20southern%20Cycads&amp;text=On%20the%20New%20South%20Wales,Spotted%20Gums%20(Corymbia%20maculata).">NSW coastline</a>, from Kempsey to Bega, and inland as far as Mudgee.</p> <p>If you’re on a road trip, now is the perfect time to talk to children about ancient moving continents, volcanoes and dinosaurs.</p> <p>Cycads are <a href="https://anpsa.org.au/APOL2009/feb09-s3.html">ancient gymnosperms</a> (cone-bearing plants) which evolved long before the Gondwanan supercontinent separated. These tough, hardy plants saw the dinosaurs come and go, and their relatives are found all around the world.</p> <p>These <a href="https://www.botanicgardens.org.au/our-science/our-collections/plant-families/cycads#:%7E:text=Not%20only%20is%20Macrozamia%20communis,inland%20as%20far%20as%20Mudgee.">cycads</a> form a striking understorey to the spotted gum. As their scientific name (<em>Macrozamia communis</em>) suggests, they form a dense community.</p> <p>Further north in Queensland, pineapple cycads (<em>Lepidozamia peroffskyana</em>), and Western Australia’s zamia palm (<em>Macrozamia riedlei</em>) are also worth spotting.</p> <p>Cycad seeds are poisonous, but First Nations Australians worked out a complex process to prepare them for <a href="https://www.apscience.org.au/apsf20036/">safe eating</a>. This involved dissolving the <a href="https://www.scienceflip.com.au/subjects/chemistry/equilibriumandacidreactions/learn10/">plant’s toxins</a> in running water, cooking, working and grinding the seeds into a powder.</p> <p>Spotted gums evolved long after dinosaurs went extinct. Early eucalypt fossils date from about 34 million years ago, while current species are often only a few million years old.</p> <p>Spotted gums are a great example of how plants that survive tough environments often also do well in difficult <a href="https://theconversation.com/the-humble-spotted-gum-is-a-world-class-urban-tree-heres-why-212540">urban situations</a>.</p> <p>Cycads are similarly found growing in poor soils and arid conditions. They have long, glossy leaves up to about 1.5 metres in length with lots of leaflets.</p> <p>There are both male and female plants. The female cone is an impressive, wide-domed structure that can be almost half a metre across. Its bright orange-red seeds are eaten by <a href="https://backyardbuddies.org.au/backyard-buddies/cycads/#:%7E:text=If%20you%20have%20a%20female,bats%20will%20feed%20on%20them.">foraging marsupials</a>, large birds and flying foxes.</p> <p>Spotted gums are tall, straight eucalyptus trees with dark green, glossy leaves. Old bark creates dark grey spots against their cream coloured trunk, giving them a mottled look.</p> <p>It is interesting to see ancient and modern species in such a close community relationship in cycad-spotted gum forests. Both are also well-adapted to the fires that frequent their habitat.</p> <h2>2. Ancient acacias</h2> <p>Travelling inland, the environment gets even tougher. Most large trees disappear and are replaced by woodlands dominated by <a href="https://www.agriculture.gov.au/sites/default/files/abares/forestsaustralia/publishingimages/forest%20profiles%202005/acacia_forests_2005.pdf">inland acacia</a> (wattle) species.</p> <p>These inland acacias are short but mighty, with deep, extensive root systems.</p> <p>Two of these species, <a href="http://theconversation.com/the-mighty-mulga-grows-deep-and-lives-long-118838">mulga</a> (<em>Acacia aneura</em>) and brigalow (<em>A. harpophylla</em>) are part of Australian folklore. A Banjo Paterson character <a href="https://gutenberg.net.au/ebooks/e00072.txt">says</a>: “You know how the brigalow grows […] saplings about as thick as a man’s arm”.</p> <p>Nutrients and water resources are limited, so mulga and brigalow trees are often evenly spaced across the landscape. This eerie symmetry makes it look like they were planted by humans.</p> <p>Many people are unaware that the twisted, stunted specimens they see are more than 250 years old and occupy vast tracts of the Australian landscape.</p> <p><a href="https://www.dcceew.gov.au/environment/biodiversity/threatened/action-plan/priority-plants/waddy-wood">Waddy-wood</a> (<em>Acacia peuce</em>) is a rare species of acacia, found in just three locations on the edge of the Simpson Desert. This tree has very strong wood, and was used by Indigenous Australians for making clubs (waddys) and tools for carrying fire.</p> <p>Inland acacias were widely used by Indigenous Australians for their wood, resins and medicinal properties. They have also been used as <a href="https://www.dpi.nsw.gov.au/__data/assets/pdf_file/0003/671421/using-mulga-as-a-forage-supplement-for-livestock-in-droughts.pdf">fodder for livestock</a>, especially during drought.</p> <p>These <a href="https://era.dpi.qld.gov.au/id/eprint/13430/1/QJAS_6%5B2%5D_1949_pp87-139_everist.pdf">crucial species</a> provide important habitat for other plants and animals. But they are under threat.</p> <p>As old trees collapse and die, there are no young trees replacing them. This is because of drought and grazing, compounded by <a href="https://www.agriculture.gov.au/sites/default/files/documents/environmental-risk-mitigation-plan-acacia.pdf">climate change</a>.</p> <p><a href="https://www.britannica.com/science/desertification">Desertification</a> – where fertile land is degraded until it essentially becomes desert – is becoming a huge problem due to the massive area dominated by acacias.</p> <h2>3. Boabs</h2> <p>If you’re driving across the Northern Territory and Western Australia, you might come across the <a href="https://theconversation.com/built-like-buildings-boab-trees-are-life-savers-with-a-chequered-past-118821">mighty boab</a> (<em>Adansonia gregoryii</em>).</p> <p>These close relatives of the African and Madagascan baobabs <a href="https://theconversation.com/baobab-trees-all-come-from-madagascar-new-study-reveals-that-their-seeds-and-seedlings-floated-to-mainland-africa-and-all-the-way-to-australia-231031">floated to Australia</a> as seeds or seedlings around 12 million years ago.</p> <p>These <a href="https://www.australiangeographic.com.au/topics/science-environment/2019/07/how-did-the-iconic-boab-tree-get-to-australia/">deciduous trees</a> live in mostly dry environments that also experience strong monsoonal-type rains. Boabs trap and store water in their trunks, allowing them not only to survive but thrive.</p> <p>Their African and Madagascan baobab relatives are sometimes called <a href="https://www.oneearth.org/species-of-the-week-african-baobab-tree/">trees of life</a>, as they support many species.</p> <p>Australian boabs are similar. They offer habitat, roosting and nesting sites. Their flowers and fruits are food sources to many species of insects and birds.</p> <p>They were – and are – important trees in First Nations cultures. Carvings and symbols on their trunks can last for more than a century, much longer than on other trees. These are called <a href="https://www.snexplores.org/article/carvings-australia-boab-trees-lost-history-first-nation">dendroglyphs</a>.</p> <p>For example, <a href="https://theconversation.com/the-boab-trees-of-the-remote-tanami-desert-are-carved-with-centuries-of-indigenous-history-and-theyre-under-threat-191676">snake carvings</a> dated to more than 200 years old have been found on boab trees in Northern Australia’s Tanami Desert.</p> <p>While these special trees are usually found far from the beaten track, they can be spotted growing around Darwin and other remote towns. If you get the chance to see them, count yourself lucky.</p> <h2>Tough terrain, tough trees</h2> <p>Plant communities are remarkably resilient. They also display great creativity when evolving ways to survive tough environments.</p> <p>Make sure to keep an eye out as you’re exploring Australia and enjoy the fascinating plants our country has to offer.<!-- Below is The Conversation's page counter tag.

Why the royal family is set to receive an eye-watering pay increase

<p>The members of the British royal family are set to receive a record-breaking pay increase, funded by British taxpayers. </p> <p>From April 2025, the amount the royals will receive from the Sovereign Grant - funded by the UK’s public purse – will jump by a whopping £45 million (A$88 million), to £132 million ($260 million).</p> <p>Not everyone is happy about this enormous pay increase, as CEO of Republic Graham Smith said that while the UK remains in the clutches of the cost of living crisis, it is not the time for such a hefty increase to one of the richest families in the world. </p> <p>“This is public money, all of this money comes from the government, at a time when the government is not able to properly fund schools, hospitals police … It is scandalous,” Smith told <em><a href="https://www.townandcountrymag.com/society/tradition/a63330811/british-royal-family-money-finances-2025/" target="_blank" rel="noopener">Town &amp; Country</a></em>.</p> <p>“Not only should it not be going up at all, it should be going down.”</p> <p>The increase was first announced last year, with Buckingham Palace officials saying at the time that a huge chunk of that extra cash will be put towards the £369 million ($728 million) bill for long-planned, necessary Palace renovations.</p> <p>The exact amount that is being allocated from this year’s Grant for the work has not been made public.</p> <p>The Grant was established in 2012 in order to help the royal family pay for expenses related to their official duties, with the vast majority usually spent on property maintenance and staffing.</p> <p>When the Grant first came into effect, there were many more working royals which required a larger pool of funding. </p> <p>Now that the royal roster has been stripped back, royal author Richard Palmer believes the public is now “getting less for their money”.</p> <p>He told <em>Town &amp; Country</em>, “I do think that the monarchy in general does a good job for the country and is part of the glue that binds us all together but that doesn’t mean that as an institution, as individuals, they should be able to avoid criticism. They are not above scrutiny.”</p> <p><em>Image credits: Shutterstock </em></p>

Donald Bradman's baggy green sells for eye-watering price

<p>Sir Donald Bradman's baggy green that he wore in his final Australian Test series has fetched nearly half a million at auction. </p> <p>The cap was worn by Bradman during the 1947-48 series, when the Indian team played on Australia soil for the first time in history. </p> <p>The baggy green fetched a whopping $390,000, with the final price totalling $479,700 including auction costs.</p> <p>It attracted significant interest from potential buyers from both Australia and overseas, with the winning buyer coming out on top after a 10 minute flurry at Bonhams Auction House in Sydney on Tuesday evening.</p> <p>The auction house described the cap as "sun faded and worn", with "some insect damage" and "some loss to edge of peak".</p> <p>The cap was also advertised as “the only known Baggy Green” to have been worn by Bradman during the series, where he cored 715 runs in six innings at an average of 178.75, with three centuries and a double-hundred.</p> <p>Bradman had gifted it to India's team manager at the time, who then gave it to the team's wicket keeper. </p> <p>While it is currently not known who placed the winning bid, the cap itself has particular significance to Indian fans, as the series took place just months after the country gained independence. </p> <p>For Aussie fans, the cap was worn during Bradman's final game on Australian soil, with the cricket legend embarking on a farewell tour of England afterwards. </p> <p>This is not the first cap of Bradman's to go under the hammer, with the cap he wore during his 1928 Test debut fetching over $450,000 plus fees in 2020.</p> <p>The late Shane Warne's baggy green currently holds the record for sale at auction, after selling for $1m when auctioned off in 2020. </p> <p><em>Image: Design Pics Inc/ Shutterstock Editorial</em></p> <p> </p>

From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<!-- Below is The Conversation's page counter tag.

Rare coin hidden for decades to fetch eye-watering sum

<p>Three sisters from the US who inherited a dime coin kept it in a bank vault for more than 40 years, and while they know it had some value, they didn't know just how much until a few years ago. </p> <p>The rare coin, struck by the US Mint in San Francisco in 1975, could be worth more than $US500,000 ($748,000), according to Ian Russell, president of GreatCollections, the auction house selling the coin. </p> <p>What makes the coin depicting President Franklin D. Roosevelt so valuable is that it is just one of two coins missing the "S" mint mark for San Francisco. </p> <p>The other dime sold for  $US682,000 (over $1 million) at a 2019 auction and then again months later to a private collector. </p> <p>While avid coin collectors have known about the existence of these two extraordinarily rare coins, their whereabouts had remained a mystery since the late 1970s. </p> <p>“They were hidden for decades,” Russell said.</p> <p>“Most major collectors and dealers have never seen one.”</p> <p>The three sisters from Ohio, who want to remain anonymous,  inherited one of the two dimes after the recent death of their of their brother, Russell said. </p> <p>They told Russell that their brother and mother bought the first error coin discovered in 1978 for $27,225, which would amount to roughly $135,000 today.</p> <p>Their parents, who ran a dairy farm, saw the coin as a financial safety net, and it was only until last year that one of the sisters saw the coin first-hand. </p> <p>Russell also said that their brother had reached out to him about seven years ago and told him about the coin, but he too kept it a secret. </p> <p>When Russell told one of the sisters about the potential value of the coin, she told him: “is that really possible?”. </p> <p>The coin, known as the “1975 ‘no S’ proof dime,” will be displayed at a coin show beginning on Wednesday in Tampa, Florida, and before <a href="https://www.greatcollections.com/Coin/1655587" target="_blank" rel="noopener">the auction</a> closes late next month, Russell said.</p> <p>The current highest bidder has offered $US250,000 ($374,000).</p> <p><em>Images: Great Collections/ Professional Coin Grading Services</em></p>

The eye-watering salaries of The Voice Australia judges revealed

<p><em>The Voice Australia</em> has revamped the lineup of the judges for the 2024 season, with American music icons Adam Lambert and LeAnn Rimes joining Aussies Guy Sebastian and Kate Miller-Heidke. </p> <p>As the new American talent joins the show, Seven are reportedly paying big buck for the international stars after their salaries were leaked by <a href="https://au.lifestyle.yahoo.com/exclusive-the-voice-australia-coaches-salaries-leaked-amid-pay-row-230921307.html" target="_blank" rel="noopener"><em>Yahoo News</em></a>. </p> <p>According to the publication, an alleged source claims that Adam and LeAnn "are believed to be receiving between $750,000 and $1.2 million" for the single season of the show. </p> <p>Meanwhile, Kate Miller-Heidke "is believed to be receiving upwards of $500,000" for her first season on the show. </p> <p>Veteran judge Guy Sebastian allegedly started on $750,000 per season in 2019, "but this is believed to now be worth $1 million". </p> <p>These new judges are getting "considerably less" than outgoing coaches Rita Ora and Jason Derulo, <em>Yahoo</em> alleges.</p> <p>According to a production insider, the reason for the switch-up of judges was the star's pay cheques, and a desire from producers to keep costs down.</p> <p>The insider said the program has been wanting a change in judges lineup for a quite some time, adding that salary increases are necessary to keep returning stars on the show and the price tag for the former crop was "too expensive".</p> <p>"The company line was that Jessica, Rita and Jason were all too busy, but I don't think anyone is too busy to pick up these sorts of pay cheques. It certainly did have a lot to do with keeping the costs down."</p> <p><em>Image credits: Seven </em></p>

Doctor shares her holy grail tips for overcoming eye sensitivity

<p>As the chill of winter sets in, many people find that their eyes become more sensitive and prone to dryness. This can be particularly challenging for those who already suffer from dry eye syndrome. </p> <p>Dr. Jacqueline Beltz is a leading Australian Ophthalmologist and the founder of <a href="https://www.okkiyo.com" target="_blank" rel="noopener">OKKIYO</a>, a beauty brand that makes PRIORITEYES mascara for people with sensitive eyes.</p> <p>Dr Beltz has shared her insights into dry eye syndrome and how winter can exacerbate symptoms, also sharing her top tips for managing eye sensitivity during the colder months.</p> <p><strong>Understanding Dry Eye Syndrome</strong></p> <p>The surface of the eye is covered by a delicate layer of tears, essential for comfort, vision, protection, and nutrition. The tear film comprises two main layers: an outer lipid (oily) layer and an inner aqueous (watery) layer. The lipid layer, produced by oil glands in the eyelids, prevents tears from evaporating too quickly, while the aqueous layer, consisting of water, electrolytes, and proteins, spreads tears evenly across the eye and helps them adhere to the surface.</p> <p>When the balance of tear production, evaporation, absorption, and drainage is disrupted, it can lead to dry eye syndrome. Symptoms may include redness, irritation, a gritty sensation, tired eyes, itching, excessive watering, and fluctuating vision. In severe cases, dry eye can be painful and significantly impact daily life.</p> <p><strong>How common is dry eye syndrome?</strong></p> <p>Dry eye syndrome is a widespread issue, particularly among older adults. According to the Blue Mountains Eye Study, 57% of adults over the age of 50 experience some degree of dry eye. This condition is notably more prevalent in women, with higher rates observed compared to their male counterparts. The increased prevalence in women is often attributed to hormonal changes, particularly during and after menopause. </p> <p>A more recent study, Optometry Australia’s 2022 Vision index found that over 85% of Australians are estimated to have experienced dry eyes at some point in their lives.  Of those affected, 55% say they only developed the condition following the beginning of the pandemic in 2020.  They reported that almost 1 in 5 (18%) of people experience dry eye symptoms frequently.  </p> <p>These statistics highlight the importance of understanding and managing dry eye, especially as we age.</p> <p><strong>DEWS II Study and Treatment Approaches</strong></p> <p>The DEWS II (Dry Eye Workshop II) study provides a comprehensive framework for understanding and treating dry eye syndrome. According to the study, dry eye is a multifactorial disease characterised by a loss of homeostasis (or balance) in the tear film, accompanied by eye symptoms. Factors such as tear film instability, hyperosmolarity (increased saltiness), inflammation, and neurosensory (altered feelings or sensations) abnormalities play significant roles.</p> <p>There are two primary types of dry eye: aqueous deficient and evaporative. Most individuals have a combination of both. Aqueous deficient dry eye occurs when there is insufficient production of the watery layer of tears, often due to aging, hormonal changes, or certain medications. Evaporative dry eye is typically caused by environmental factors or conditions affecting the lipid layer, such as meibomian gland dysfunction (MGD).</p> <p><strong>Winter's Impact on Dry Eyes</strong></p> <p>Winter poses unique challenges for dry eye sufferers. Cold, dry air, indoor heating, and wind can all exacerbate symptoms. Here's how to combat these winter-specific issues:</p> <p><em><strong>1. Humidify Your Environment</strong></em></p> <p>Indoor heating reduces humidity levels, leading to increased tear evaporation. Consider using a humidifier to maintain moisture in the air, especially in bedrooms and living spaces. This helps keep your eyes hydrated.</p> <p><em><strong>2. Protect Your Eyes Outdoors</strong></em></p> <p>Cold winds can strip away the tear film. When outside, wear wraparound sunglasses to shield your eyes from the elements. This not only protects your eyes from the wind but also from UV rays, which can be strong even in winter.</p> <p><em><strong>3. Stay Hydrated</strong></em></p> <p>Dehydration can worsen dry eye symptoms. Drink plenty of water throughout the day to maintain overall hydration, which supports healthy tear production.</p> <p><em><strong>4. Optimise Your Diet</strong></em></p> <p>Certain foods can promote eye health. Omega-3 fatty acids, found in fish like salmon and flaxseeds, have anti-inflammatory properties that can help manage dry eye symptoms. Incorporate these into your diet for added benefits.</p> <p><em><strong>5. Use a Warm Compress</strong></em></p> <p>A warm compress can help improve the function of the meibomian glands, which produce the oily layer of the tear film. This is particularly helpful for those with meibomian gland dysfunction, or MGD. Gently apply a warm, damp cloth to your closed eyelids for 10-15 minutes, followed by a gentle massage of the eyelids to encourage oil secretion. It is important to avoid rubbing or compressing the eyeballs.</p> <p><em><strong>6. Use Over-the-Counter Lubricant Eye Drops</strong></em></p> <p>Artificial tears can provide temporary relief by supplementing the natural tear film. Choose preservative-free options to avoid further irritation, and use them frequently.</p> <p><em><strong>7.  Remember to have regular eye checks</strong></em></p> <p>In Australia, Optometrists provide our primary eye health check ups. Dr Beltz recommends adults over the age of 40 see their optometrist once a year, but if you’re struggling with symptoms of dry eye in winter, an extra check up might help and your optometrist will be able to help you to come up with an individualised treatment plan.</p> <p><em><strong>8. Invest in Quality Eye Products</strong></em></p> <p>For those who wear makeup, using products designed for sensitive eyes is crucial. <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara" target="_blank" rel="noopener">PRIORITEYES</a> mascara by OKKIYO has been specifically formulated to be gentle on sensitive eyes, avoiding common irritants while providing excellent performance.</p> <p><strong>Managing Dry Eye in Winter: A Recap</strong></p> <p>Winter can be tough on our eyes, but with the right strategies, you can manage dry eye symptoms effectively. Maintain a humid environment, protect your eyes from cold winds, stay hydrated, and incorporate eye-healthy foods into your diet. Regularly use warm compresses and opt for gentle, high-quality eye products like PRIORITEYES mascara.  </p> <p>Dry eye syndrome may be a common condition, but it doesn't have to dominate your life, especially during the harsh winter months. With these tips, you can keep your eyes comfortable and healthy all season long. For personalised advice and treatment, always consult with your eye care professional.</p> <p>Stay warm, stay hydrated and take care of your eyes this winter!</p> <p><em>Image credits: Shutterstock </em></p>

Eye infections might seem like a minor complaint – but in some cases they can cause blindness and even death

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>When you think of eye infections, what comes to mind? Puffy, swollen bruised feeling eyelids that get glued together with gunk overnight? That feeling of having grit in your eye that can’t be cleaned away? Eye infections may seem like a relatively minor – if unsightly and inconvenient – complaint, but they can also be far more serious.</p> <p>Take the deadly outbreak of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5022785/">antibiotic resistant</a> bacteria <a href="https://www.cff.org/managing-cf/burkholderia-cepacia-complex-b-cepacia"><em>Burkholderia cepacia</em></a> in 2023-24, for example.</p> <p>Between January 2023 and February 2024, contaminated brands of lubricating eye gel were linked to the infection of at least 52 patients. <a href="https://www.independent.co.uk/news/health/contaminated-eye-gel-outbreak-death-b2523446.html">One person died</a> and at least 25 others suffered serious infections.</p> <p>The outbreak has now subsided and products are <a href="https://www.gov.uk/drug-device-alerts/specific-brands-of-carbomer-eye-gel-recall-of-aacarb-eye-gel-aacomer-eye-gel-and-puroptics-eye-gel-potential-risk-of-infection-dsi-slash-2023-slash-11#update-2-april-2024">back on the shelves</a> but it isn’t the first time that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8335909/">medicinal products</a> have led to outbreaks of <em>B cepacia</em>.</p> <p>The bacterium is an opportunistic pathogen known to pose a significant risk to people with cystic fibrosis, chronic lung conditions and weakened immune systems. The infection likely progresses from the mucous membranes of the eyelids to the lungs where it leads to pneumonia and septicaemia causing <a href="https://erj.ersjournals.com/content/17/2/295">death in days</a>.</p> <p>But it’s not just <em>B cepacia</em> that can threaten our health. Something as simple as rubbing our eyes can introduce pathogens leading to infection, blindness and, in the worst case, death.</p> <p>Bacteria account for up to <a href="https://pubmed.ncbi.nlm.nih.gov/16148850/">70% of eye infections</a> and globally <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9032492/">over 6 million people</a> have blindness or moderate visual impairment from ocular infection. Contact lens wearers are at <a href="https://www.aao.org/eye-health/diseases/contact-lens-related-eye-infections">increased risk</a>.</p> <figure><iframe src="https://www.youtube.com/embed/pWsx8i1kaxs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The eye is a unique structure. It converts light energy to chemical and then electrical energy, which is transmitted to the brain and converted to a picture. The eye uses about <a href="https://www.ncbi.nlm.nih.gov/books/NBK11556/">6 million cones and 120 million rods</a> which detect colour and light.</p> <p>Eye cells have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8775779/">no ability to regenerate</a> so, once damaged or injured, cannot be repaired or replaced. The body tries its best to preserve the eyes by encasing them in a <a href="https://www.ncbi.nlm.nih.gov/books/NBK531490/">bony protective frame</a> and <a href="https://www.ncbi.nlm.nih.gov/books/NBK482428/">limiting exposure</a> having eyelids to defend against the environmental damage and ensure the eyes are kept lubricated.</p> <p>Despite our bodies’ best efforts to shield the eyes from harm, there are a number of common eye infections that can result from introducing potential pathogens into the eyes.</p> <h2>Conjunctivitis</h2> <p>The outer-most layer of the eye, the sclera, bears the brunt of exposure and to help protect it, it is lined by a thin moist membrane called the <a href="https://my.clevelandclinic.org/health/body/24329-conjunctiva">conjunctiva</a>.</p> <figure><iframe src="https://www.youtube.com/embed/RZ4danuJwd0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The conjunctiva is <a href="https://innovations.bmj.com/content/9/4/253">highly vascularised</a>, which means it has lots of blood vessels. When microbes enter the eye, it is this layer that mounts an immune response causing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8328962/">blood vessels to dilate</a> in the conjunctiva. This results in <a href="https://www.cdc.gov/conjunctivitis/about/symptoms.html">“pink eye”</a>, a common form of conjunctivitis. Conjunctivitis can be caused by bacteria, allergens or viruses and typically heals by itself.</p> <h2>Blepharitis</h2> <p>Blepharitis is an inflammation of the eyelid and usually affects both sides. It can cause itchy eyes and dandruff-like flakes. It’s most commonly caused by <a href="https://www.tandfonline.com/doi/pdf/10.3109/09273948.2013.870214"><em>Staphylococcus</em> bacteria</a>, or the <a href="https://cks.nice.org.uk/topics/blepharitis/background-information/causes/">dysfunction of the glands</a> of the eyelids. It can be treated by <a href="https://www.nhs.uk/conditions/blepharitis/">cleaning the eyes</a> regularly.</p> <h2>Stye</h2> <p>A stye (also called <a href="https://www.college-optometrists.org/clinical-guidance/clinical-management-guidelines/hordeolum">hordeolum</a>) is a painful infection of the upper or lower eyelid. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5370090/">Internal styes</a> are caused by infection of an oil-producing gland inside the eyelid, whereas <a href="https://pubmed.ncbi.nlm.nih.gov/28723014/">external styes</a> develop at the base of the eyelash because of an infection of the hair follicle. Both are caused by bacteria, typically <a href="https://jamanetwork.com/journals/jamaophthalmology/fullarticle/1874715">the <em>S aureus</em> form of the <em>Staphylococcus</em> species</a>.</p> <figure><iframe src="https://www.youtube.com/embed/INKrGOdy824?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Styes can be treated by holding a clean flannel soaked in warm water against the affected eye for five to ten minutes, three or four times a day. Do not try to burst styes – this could spread the infection.</p> <h2>Keratitis</h2> <p>Keratitis is the inflammation of the cornea, the transparent part of the eye that light passes through. The cornea is part of the eye’s main barrier against dirt, germs, and disease. Severe keratitis can cause ulcers, damage to the eye and even blindness.</p> <p>The most common type is bacterial keratitis; however, it can also be caused by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7998329/">amoeba</a>, which can migrate to other parts of the body – including the brain – and cause infection and <a href="https://theconversation.com/nasal-rinsing-why-flushing-the-nasal-passages-with-tap-water-to-tackle-hay-fever-could-be-fatal-225811">even death</a>.</p> <p>Noninfectious keratitis is most commonly caused by wearing contact lenses for too long, especially while sleeping. This can cause scratches, dryness and soreness of the cornea, which leads to inflammation.</p> <h2>Uveitis</h2> <p><a href="https://www.nhs.uk/conditions/uveitis/">Uveitis</a> is inflammation of the middle layer of the eye. Although relatively rare, it is a serious condition and usually results from viral infections such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8501150/">herpes simplex</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29023181/">herpes zoster</a> or <a href="https://link.springer.com/chapter/10.1007/978-3-319-09126-6_40">trauma</a>. Depending on where the inflammation is in the eye, the symptoms can be anything from redness, pain and floaters to blurred vision and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1772296/">partial blindness</a>.</p> <h2>Exogenous endophthalmitis</h2> <p>This is a rare but serious infection caused by eye surgery complications, penetrating ocular trauma (being stabbed in the eye with a sharp object) or foreign bodies in the eye. Foreign bodies can be anything from dirt and dust to small projectiles such as shards of metal from drilling, explosives or soil from farm machinery and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7286045/">many other sources</a>.</p> <h2>Dacryocystitis</h2> <p>Dacryocystitis is the inflammation of the nasolacrimal sac, which drains tears away from the eye into the nose. This condition can be <a href="https://pubmed.ncbi.nlm.nih.gov/8443113/">acute</a>, <a href="https://www.nature.com/articles/6700662">chronic</a> or <a href="https://www.jebmh.com/articles/a-study-of-congenital-dacryocystitis.pdf.pdf">acquired at birth</a>. Most cases are caused by <a href="https://bmcophthalmol.biomedcentral.com/articles/10.1186/s12886-020-01792-4"><em>Streptococcus pneumoniae</em> and <em>Staphylococcus aureus</em></a> bacteria.</p> <p>The condition mainly affects newborns and those over 40. Seventy-five per cent of cases are women and it’s most commonly found in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6039673/">white adults</a>. It can lead to the stagnation of tears, creating a breeding ground for microbes.</p> <h2>Careful with contacts</h2> <p>Proper eye hygiene reduces the risk of all these conditions – and this is even more important for contact lens wearers.</p> <figure><iframe src="https://www.youtube.com/embed/uENHAntJOIA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Appropriate hygienic cleaning of lenses is paramount. <a href="https://pubmed.ncbi.nlm.nih.gov/30789440/">Non-sterile water</a>, <a href="https://www.aao.org/eye-health/glasses-contacts/contact-lens-care">spit</a> and other fluids can transfer <a href="https://www.science.org/content/article/bacteria-living-your-contact-lens-solution">potentially dangerous</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482476/">microbes</a> into the eye – a warm, moist environment that makes an ideal breeding ground for bacteria – leading to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9542356/">localised infection</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3972779/">blindness</a> or progress to a more serious <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9835757/">systemic infection or death</a>.</p> <p>Any persistent and painful redness or swelling of eyes should be checked by a registered health professional.<!-- Below is The Conversation's page counter tag.

What’s going on?</p> <p>Some people start to wear spectacles for the first time and perceive their vision is “bad” when they take their glasses off. They incorrectly interpret this as the glasses making their vision worse. Fear of this might make them <a href="https://www.bbc.com/future/article/20140513-do-glasses-weaken-your-eyesight#:%7E:text=A%20study%20from,they%20are%20right%3F">less likely to wear their glasses</a>.</p> <p>But what they are noticing is how much better the world appears through the glasses. They become <a href="https://www.tandfonline.com/doi/full/10.1080/2576117X.2022.2033588">less tolerant</a> of a blurry world when they remove them.</p> <p>Here are some other things you might notice about eyesight and wearing glasses.</p> <h2>Lazy eyes?</h2> <p>Some people sense an increasing reliance on glasses and wonder if their eyes have become “lazy”.</p> <p>Our eyes work in much the same way as an auto-focus camera. A flexible lens inside each eye is controlled by muscles that let us <a href="https://www.aao.org/museum-eye-openers/how-does-eye-focus">focus on objects</a> in the distance (such as a footy scoreboard) by relaxing the muscle to flatten the lens. When the muscle contracts it makes the lens steeper and more powerful to see things that are much closer to us (such as a text message).</p> <p>From the age of about 40, the lens in our eye <a href="https://theconversation.com/why-we-lose-our-hearing-and-vision-as-we-age-67930">progressively hardens</a> and loses its ability to change shape. Gradually, we lose our capacity to focus on near objects. This is called “<a href="https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/presbyopia">presbyopia</a>” and at the moment there are no treatments for this lens hardening.</p> <p>Optometrists correct this with prescription glasses that take the load of your natural lens. The lenses allow you to see those up-close images clearly by providing extra refractive power.</p> <p>Once we are used to seeing clearly, our tolerance for blurry vision will be lower and we will reach for the glasses to see well again.</p> <h2>The wrong glasses?</h2> <p>Wearing old glasses, the wrong prescription (or even someone else’s glasses) won’t allow you to see as well as possible for day-to-day tasks. It could also cause <a href="https://headaches.org/readers-mail-glasses-causing-headache/">eyestrain and headaches</a>.</p> <p>Incorrectly prescribed or dispensed prescription glasses can lead to vision impairment in children <a href="https://iovs.arvojournals.org/article.aspx?articleid=2126392">as their visual system is still in development</a>.</p> <p>But it is more common for kids to develop long-term vision problems as a result of <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">not wearing glasses when they need them</a>.</p> <p>By the time children are about 10–12 years of age, wearing incorrect spectacles is less likely to cause their eyes to become lazy or damage vision in the long term, but it is likely to result in <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">blurry or uncomfortable vision</a> during daily wear.</p> <p><a href="https://goodvisionforlife.com.au/">Registered optometrists in Australia</a> are trained to assess refractive error (whether the eye focuses light into the retina) as well as the different aspects of ocular function (including how the eyes work together, change focus, move around to see objects). All of these help us see clearly and comfortably.</p> <h2>What about dirty glasses?</h2> <p>Dirty or scratched glasses can give you the impression your vision is worse than it actually is. Just like a window, the dirtier your glasses are, the more difficult it is to see clearly through them. <a href="https://www.optometry.org.au/wp-content/uploads/GVFL/Brochure_PDFs/Care-for-Glasses-2018-A4-single-page-final.pdf">Cleaning glasses regularly</a> with a microfibre lens cloth will help.</p> <p>While dirty glasses are not commonly associated with eye infections, some research suggests dirty glasses can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">harbour bacteria</a> with the remote but theoretical <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6628431/#:%7E:text=59%2C60%5D.-,S.,39%2C40%2C41%5D.">potential to cause eye infection</a>.</p> <p>To ensure best possible vision, people who wear prescription glasses every day should clean their lenses at least every morning and twice a day where required. Cleaning frames with alcohol wipes can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">reduce bacterial contamination by 96%</a> – but care should be taken as alcohol can damage some frames, depending on what they are made of.</p> <h2>When should I get my eyes checked?</h2> <p><a href="https://goodvisionforlife.com.au/faqs/">Regular eye exams</a>, starting just before school age, are important for ocular health. Most prescriptions for corrective glasses <a href="https://www.ahpra.gov.au/documents/default.aspx?record=WD16%2F20156&amp;dbid=AP&amp;chksum=676U2aH1QM4XJ6ICVAVaKg%3D%3D">expire within two years</a> and contact lens prescriptions often expire after a year. So you’ll need an eye check for a new pair every year or so.</p> <p>Kids with ocular conditions such as progressive myopia (short-sightedness), strabismus (poor eye alignment), or amblyopia (reduced vision in one eye) will need checks at least every year, but likely more often. Likewise, people over 65 or who have known eye conditions, such as <a href="https://goodvisionforlife.com.au/vision-problems/glaucoma/">glaucoma</a>, will be recommended more frequent checks.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6706420/">online prescription estimator</a> is no substitute for a full eye examination. If you have a valid prescription then you can order glasses online, but you miss out on the ability to check the fit of the frame or to have them adjusted properly. This is particularly important for multifocal lenses where even a millimetre or two of misalignment can cause uncomfortable or blurry vision.</p> <p>Conditions such as <a href="https://www.cdc.gov/diabetes/managing/diabetes-vision-loss.html#:%7E:text=Diabetic%20retinopathy%20is%20caused%20when,vision%20or%20stopping%20blood%20flow.">diabetes</a> or <a href="https://www.ncbi.nlm.nih.gov/books/NBK525980/">high blood pressure</a>, can affect the eyes so regular eye checks can also help flag broader health issues. The vast majority of eye conditions can be treated if caught early, highlighting the importance of regular preventative care.<!-- Below is The Conversation's page counter tag.

12 best yoga poses to strengthen bones

<p><em>A rehabilitation doctor and yogi of 50 years says your yoga practise is doing way more than centring your mind and opening your joints.</em></p> <p>If you’re like many yoga lovers, you appreciate how this one physical activity can be so beneficial, while simultaneously so gentle. Few other practises stretch your body, calm your mind or help regulate vitals, such as your heart rate and blood pressure, in quite the way a regular yoga session can do.</p> <p>Researcher and rehabilitation doctor, Dr Loren Fishman has also been a practitioner of yoga for 50 years and is the creator of ‘the Fishman method’ of yoga for osteoporosis. In a conversation with Reader’s Digest, Dr Fishman points out that for all its advantages, yoga can also provide a powerful boost to your long-term bone density. In particular, Dr Fishman published 12 yoga poses in Orthopedic Nursing that are particularly great for strengthening your bones.</p> <p>Of these 12 poses Dr Fishman says: “They all work by putting pressure on the bones of sufficient magnitude and duration.” He says this can “stimulate the osteoblasts to make more bone”, thanks to their placement of “maximum torque, compression or pressure” on particular body parts, as outlined below.</p> <p>So, while a good yoga session is a helpful tool to help you get through the week, its effects are longer-lasting than you realised.</p> <p>Keep reading for the 12 best yoga poses to strengthen your bones. (“With all poses, remember not to round the spine as you go into and out of the poses, and within the poses themselves,” Dr Fishman advises.)</p> <p><em>Whether you’re a yoga beginner or expert, it’s important you have the right mat. <a href="https://gaiam.innovations.com.au/p/gaiam-yoga/mats?affiliate=GAIAM60" target="_blank" rel="noopener">Check out these mats from Gaiam.</a> </em></p> <p><strong>1. Tree pose (Vriksasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/1-yoga-tree-pose-GettyImages-1094418370-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Tree pose has a special way of calling you to stillness. Dr Fishman says tree pose also adds pressure that can strengthen the upper femur and hip. He adds that a study at the University of Southern California (USC) showed a 60 per cent increase in pressure, even with the foot placed three-quarters down the calf.</p> <p>Dr Fishman says tree pose is “also extremely valuable for improving balance and avoiding falls,” although he reminds us that the raised foot should always go above or below the knee – never directly on the knee joint.</p> <p><strong>2. Triangle pose (Trikonasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/2-yoga-triangle-pose-GettyImages-1317111194-Jvedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Triangle pose “puts torque on the lumbar spine, the neck of the femur, the hips and ribs,” Dr Fishman says, adding that this is another pose that will help improve balance.</p> <p><em>Look and feel the part in these <a href="https://gaiam.innovations.com.au/p/gaiam-apparel/apparel?affiliate=GAIAM60" target="_blank" rel="noopener">comfortable yoga clothes from Gaiam</a>.</em></p> <p><strong>3. Reverse Triangle Pose (Parivrtta Trikonasan) </strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/3-yoga-reverse-triangle-pose-GettyImages-1154825406-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Dr Fishman says great pressures develop on the proximal femurs (very top of the femur bone that connects with the hip joint) in this pose, as well as the hip and lower back. Reverse triangle also puts helpful pressure in the ribs and wrists and is “a very powerful balance-improver.”</p> <p><strong>4. Warrior 2 (Virabhadrasana II)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/4-yoga-warrior-pose-GettyImages-1291770866-Jvedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>“Fabulous mechanical disadvantage means great pressure on the entire forward (bent leg) femur,” Dr Fishman says of full warrior pose. He explains that “the straight leg’s rotation works on the head of femur and hip,” helping to strengthen the upper leg and hip. This is yet another pose that he says helps with balance.</p> <p><strong>5. Side angle pose (Parsvakonasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/5-yoga-side-angle-pose-GettyImages-1355155879-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Another boon for balance, Dr Fishman says side angle pose torques the lower back and the top of the femur – all good things – and stimulates the bone-making cells of the hip, too.</p> <p><em>Keep your workout going with this <a href="https://gaiam.innovations.com.au/p/gaiam-wellness/restore-massage/27-73270-gaiam-performance-no-knots-massage-ball?affiliate=GAIAM60" target="_blank" rel="noopener">no-knots massage ball from Gaiam</a> – perfect for releasing tension and relieving stiffness.</em></p> <p><strong>6. Locust pose (Salabhasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/6-yoga-locus-pose-GettyImages-840155180-Jvedit-1280.jpg" alt="" /></strong></p> <p>Locust pose “raises pressures, which stimulate bone-making in the posterior elements of the spine,” Dr Fishman says, while it also helps balance some the forward focus on the ribs of the earlier poses. Locust pose also strengthens extensor muscles of the back to improve posture and reverse curvature of the spine in the upper back, which can lead to fractures.</p> <p><strong>7. Bridge pose (Setu Bandhasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/7-yoga-bridge-pose-GettyImages-470128454-Jvedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Dr Fishman says bridge pose can help strengthen the ribs and lower regions of the spine.</p> <p><strong>8. Reclining hand to big toe (Supta Padangusthasana I)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/8-yoga-hamstring-stretch-GettyImages-1281872287-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>Also known to be a good hamstring stretch, this pose facilitates “extreme pressure brought to bear on relevant sections” of the femur, hip, pelvis (specifically the sitz bones) and spine.</p> <p>Seated versions of this and the following pose offer less intensity, but Dr Fishman cautions for both: “The seated versions have the potential to be dangerous. Keep the spine straight and against the back of the chair. Do not round the back.”</p> <p><strong>9. Supine hand to big toe 2 (Supta Padangusthasana II)</strong></p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/9-yoga-stretch-GettyImages-637025028-Jvedit-1280.jpg" alt="" width="1280" height="720" /></p> <p>In the side extension variation of this pose, there is “extreme pressure brought to bear” on the upper femur, hip, pubis, ribs, and spine, he says.</p> <p><strong>10. Straight-legged twist (Marichyasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/10-yoga-twist-GettyImages-1248883385-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>This “puts great pressure” on the sitz bones and pelvis, as well as “great but safe pressure” on the spine.</p> <p><strong>11. Bent-leg twist (Matsyendrasana)</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2024/04/11-yoga-twist-bent-leg-GettyImages-1133155224-JVedit-1280.jpg" alt="" width="1280" height="720" /></strong></p> <p>The bent-leg twist “puts great pressure” on the upper femur and pelvis, plus “great but safe pressure” on the vertebra. Dr Fishman suggests you should hug the leg to ensure a straight spine.</p> <p><em>Staying hydrated during your yoga session is vital to maintain muscle health. <a href="https://gaiam.innovations.com.au/p/takeya/water-bottles-actives-range?affiliate=GAIAM60" target="_blank" rel="noopener">Check out these insulated stainless-steel water bottles</a> designed for every kind of workout. </em></p> <p><strong>12.

6 major benefits of doing yoga every day, from experts

<h2>Positive effects of yoga</h2> <p>Sometimes it’s the simplest daily practice that can have the biggest impact on your health, and yoga is proof of that. Although most forms of yoga aren’t considered to be as intense as other workout regimens (think your average cycling class!), practising yoga on a daily basis has been scientifically demonstrated to help you mentally and physically. Through breath work, meditation and holding poses that increase strength and flexibility, the body and mind reap benefits from yoga that positively impact your long-term health. It’s no wonder people have been practising yoga for over 5000 years, and that the number of Australians practising yoga doubled between 2008 and 2017 to over two million, according to the Australian Bureau of Statistics.</p> <p>In order to get the full scope of what practising yoga daily can really do for your body, we spoke with several experts who have seen the ways yoga has positively benefited their students, patients… and even themselves.</p> <p><a href="https://gaiam.innovations.com.au/p/gaiam-yoga/mats?affiliate=GAIAM60" target="_blank" rel="noopener">Keen to try? You’ll need a mat. There’s a range of mats to suit every yoga level, check out these we recommend.</a></p> <h2>Yoga assists with mood regulation</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty2.jpg" alt="" width="1280" height="720" /></p> <p>Yoga teacher, Jenni Tarma, shares, “We have a wealth of research demonstrating that a regular mindfulness practice – the act of paying attention to the sensation in the body, thoughts and emotions without judgment – can reduce stress and help us to feel calmer, more productive, and generally more even-keeled in our daily lives.”</p> <p>After evaluating yoga history and research, one 2014 review published in Frontiers in Human Neouroscience concluded that regular yoga practice can help facilitate self-regulation (the ability to understand and manage your behaviour and reactions). Another study of adolescents between the ages of 13 and 18 found that practising yoga positively benefited emotional regulation and self-esteem. “Movement releases beneficial neurotransmitters in the brain, which helps us feel good as well as assist in mood regulation,” says yoga instructor, Evan Lawrence. “One of the things that I like about yoga specifically is that there is simultaneously a focus on physical movement and breathing.”</p> <p><a href="https://www.readersdigest.com.au/culture/23-instant-mood-boosters-you-wont-want-to-live-without" target="_blank" rel="noopener">Don’t miss these instant mood boosters you won’t want to live without.</a></p> <h2>Yoga builds up your core strength</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_shutterstock3.jpg" alt="" width="1280" height="720" /></p> <p>Personal trainer and yoga teacher, Gina Newton, says, “From a physical perspective, yoga is so great for increasing our core strength, which should be a non-negotiable part of every human’s workout.” Newton adds, “We all need our core – and especially women who have been pregnant or had children, our core strength is something we need to care for and nurture to hold us up.”</p> <p>According to Harvard Medical School, a stronger core benefits the body in multiple ways, including providing better posture, balance, stability, relief for lower back pain, and support through daily tasks like cleaning, working, and athletic activities or exercise.</p> <p>Wearing comfortable yoga gear will help you get the most out of your workout. <a href="https://gaiam.innovations.com.au/p/gaiam-apparel/apparel?affiliate=GAIAM60" target="_blank" rel="noopener">Check out these yoga clothes from Gaiam.</a></p> <h2>Yoga reduces stress</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty4.jpg" alt="" width="1280" height="720" /></p> <p>“Yoga and meditation are powerful tools for stress resilience and strengthening mental health,” says holistic healthcare practitioner and yoga instructor, Nicole Renée Matthews.  “Doing yoga regularly promotes mental clarity and calmness, centres and relaxes the mind, helps to relieve stress patterns and anxiety, and boosts concentration and focus.”</p> <p>One 2010 study from the Journal of Alternative and Complementary Medicine concluded that practising yoga can improve mood and decrease anxiety even more than a regular walking practice after participants finished a 12-week program. Researchers have also found that the breath-taking techniques involved with yoga can be part of what benefits decreased anxiety during practice.</p> <p>“Breath awareness, another key component of yoga, has been shown to reduce physiological markers of stress, especially when using techniques such as ‘belly breathing’ – breathing deeply so that the abdomen expands, rather than exclusively using a shallow chest breath – and elongating the exhalation,” says Tarma. “These techniques help to activate the parasympathetic nervous system, which in turn leads to less anxiety, jitteriness, and improved sleep; all things that can improve our mental health on a day-to-day basis.”</p> <p><a href="https://www.readersdigest.com.au/healthsmart/conditions/mental-health/10-science-backed-ways-to-lower-your-stress-this-instant-really" target="_blank" rel="noopener">Don’t miss these science-backed ways to lower your stress this instant (really!).</a></p> <h2>Yoga improves brain health</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty5.jpg" alt="" width="1280" height="720" /></p> <p>According to associate professor of psychiatry, Dr Gail Saltz, practising yoga “improves overall blood flow to the body, including the brain, [which is] helpful for cognition and memory.”</p> <p>One 2019 review published in Brain Plasticity concluded that behavioural interventions like yoga can help “mitigate age-related and neurodegenerative decline” due to the positive effects a daily practice has on different parts of the functioning brain, like the hippocampus (which plays a major role in learning and memory) and the prefrontal cortex (cognitive control functions).</p> <p>Staying hydrated is key to maintaining optimum brain health. <a href="https://gaiam.innovations.com.au/p/takeya/water-bottles-actives-range?affiliate=GAIAM60" target="_blank" rel="noopener">These drink bottles can help you keep your water intake up throughout the day.</a></p> <h2>Yoga improves flexibility and mobility</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_shutterstock6.jpg" alt="" width="1280" height="720" /></p> <p>“Physically, daily yoga practice allows us to engage our muscles and move through larger ranges of joint motion than we do typically moving through life,” says Lawrence. “This helps to keep us limber and flexible.”</p> <p>“Dedicated, daily yoga practice helps with flexibility and strength, which can help improve your posture, as well as balance,” says yoga instructor, Samantha Hoff. “On the physical side, it also helps with joint mobility since you’ll take your joints through most – or all – of their ranges of motion.”</p> <p><a href="https://www.readersdigest.com.au/healthsmart/12-best-yoga-poses-to-strengthen-bones" target="_blank" rel="noopener">Here are the best yoga poses to strengthen bones.</a></p> <h2>Yoga strengthens muscle and endurance</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2024/03/6benefitsyoga_getty7.jpg" alt="" width="1280" height="720" /></p> <p>“From a musculoskeletal perspective,” says Tarma, “yoga loads our bodies and joints in a wide variety of positions and scenarios: think longer static holds in poses that challenge our tissues’ endurance, or controlled transitions between shapes that develop strength, control and coordination. These different facets of our movement capabilities all contribute to better overall function and load-tolerance capacity. As an added bonus, because most styles of yoga are bodyweight only and move at a very moderate speed, yoga is also a generally very accessible and safe movement modality.”</p> <p>Yoga is the ultimate self-care activity. <a href="https://gaiam.innovations.com.au/p/gaiam-yoga/accessories/27-73312-gaiam-performance-hold-everything-yoga-backpack-bag?affiliate=GAIAM60" target="_blank" rel="noopener">Whether you do it at a studio or in the park, this handy yoga backpack bag stores everything you need for a calm yoga workout.</a></p> <p><strong>This article, written by Kiersten Hickman, originally appeared on</strong><strong> <a href="https://www.readersdigest.com.au/culture/6-major-benefits-of-doing-yoga-every-day-from-experts" target="_blank" rel="noopener">Reader's Digest</a>.</strong></p> <p><em>Images: Shutterstock | Getty</em></p>

This allowed us to see how different types of exercise compared, instead of lumping all types together.</p> <p>We found walking, running, strength training, yoga and mixed aerobic exercise were about as effective as <a href="https://theconversation.com/explainer-what-is-cognitive-behaviour-therapy-37351">cognitive behaviour therapy</a> – one of the <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2018.00004/full">gold-standard treatments</a> for depression. The effects of dancing were also powerful. However, this came from analysing just five studies, mostly involving young women. Other exercise types had more evidence to back them.</p> <p>Walking, running, strength training, yoga and mixed aerobic exercise seemed more effective than antidepressant medication alone, and were about as effective as exercise alongside antidepressants.</p> <p>But of these exercises, people were most likely to stick with strength training and yoga.</p> <p><iframe id="cZaWb" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/cZaWb/2/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Antidepressants certainly help <a href="https://www.thelancet.com/article/S0140-6736(17)32802-7/fulltext">some people</a>. And of course, anyone getting treatment for depression should talk to their doctor <a href="https://australia.cochrane.org/news/new-cochrane-review-explores-latest-evidence-approaches-stopping-long-term-antidepressants">before changing</a> what they are doing.</p> <p>Still, our evidence shows that if you have depression, you should get a psychologist <em>and</em> an exercise plan, whether or not you’re taking antidepressants.</p> <h2>Join a program and go hard (with support)</h2> <p>Before we analysed the data, we thought people with depression might need to “ease into it” with generic advice, <a href="https://www.who.int/initiatives/behealthy/physical-activity">such as</a> “some physical activity is better than doing none.”</p> <p>But we found it was far better to have a clear program that aimed to push you, at least a little. Programs with clear structure worked better, compared with those that gave people lots of freedom. Exercising by yourself might also make it hard to set the bar at the right level, given low self-esteem is a symptom of depression.</p> <p>We also found it didn’t matter how much people exercised, in terms of sessions or minutes a week. It also didn’t really matter how long the exercise program lasted. What mattered was the intensity of the exercise: the higher the intensity, the better the results.</p> <h2>Yes, it’s hard to keep motivated</h2> <p>We should exercise caution in interpreting the findings. Unlike drug trials, participants in exercise trials know which “treatment” they’ve been randomised to receive, so this may skew the results.</p> <p>Many people with depression have physical, psychological or social barriers to participating in formal exercise programs. And getting support to exercise isn’t free.</p> <p>We also still don’t know the best way to stay motivated to exercise, which can be even harder if you have depression.</p> <p>Our study tried to find out whether things like setting exercise goals helped, but we couldn’t get a clear result.</p> <p>Other reviews found it’s important to have a <a href="https://pubmed.ncbi.nlm.nih.gov/31923898/">clear action plan</a> (for example, putting exercise in your calendar) and to <a href="https://pubmed.ncbi.nlm.nih.gov/19916637/">track your progress</a> (for example, using an app or smartwatch). But predicting which of these interventions work is notoriously difficult.</p> <p>A <a href="https://www.nature.com/articles/s41586-021-04128-4">2021 mega-study</a> of more than 60,000 gym-goers <a href="https://www.nature.com/articles/s41586-021-04128-4/figures/1">found</a> experts struggled to predict which strategies might get people into the gym more often. Even making workouts fun didn’t seem to motivate people. However, listening to audiobooks while exercising helped a lot, which no experts predicted.</p> <p>Still, we can be confident that people benefit from personalised support and accountability. The support helps overcome the hurdles they’re sure to hit. The accountability keeps people going even when their brains are telling them to avoid it.</p> <p>So, when starting out, it seems wise to avoid going it alone. Instead:</p> <ul> <li> <p>join a fitness group or yoga studio</p> </li> <li> <p>get a trainer or an exercise physiologist</p> </li> <li> <p>ask a friend or family member to go for a walk with you.</p> </li> </ul> <p>Taking a few steps towards getting that support makes it more likely you’ll keep exercising.</p> <h2>Let’s make this official</h2> <p>Some countries see exercise as a backup plan for treating depression. For example, the American Psychological Association only <a href="https://www.apa.org/depression-guideline/">conditionally recommends</a> exercise as a “complementary and alternative treatment” when “psychotherapy or pharmacotherapy is either ineffective or unacceptable”.</p> <p>Based on our research, this recommendation is withholding a potent treatment from many people who need it.</p> <p>In contrast, The Royal Australian and New Zealand College of Psychiatrists <a href="https://www.ranzcp.org/getmedia/a4678cf4-91f5-4746-99d4-03dc7379ae51/mood-disorders-clinical-practice-guideline-2020.pdf">recommends</a> vigorous aerobic activity at least two to three times a week for all people with depression.</p> <p>Given how common depression is, and the number failing to receive care, other countries should follow suit and recommend exercise alongside front-line treatments for depression.</p> <p><em>I would like to acknowledge my colleagues Taren Sanders, Chris Lonsdale and the rest of the coauthors of the paper on which this article is based.</em></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.

"Pathetic": Council slammed after move against FREE health program

<p>A woman who runs a free mental health yoga program has been ordered to pay the council $10,000 because her classes at St Kilda beach in Melbourne have become too popular. </p> <p>The City of Port Phillip Council was slammed for their actions after they told Eliza Hilmer she must pay them hundreds of dollars  per session for her <em>Feel Good Flows </em>classes.</p> <p>Hilmer, who does not make a profit from the classes, said she started the program during the pandemic to help people manage their mental health. </p> <p>“I play by the rules as much as I can,”  Hilmer told <em>Yahoo News</em>, adding that she acquired personal trainer permit as requested by the council. </p> <p>“We’ve been operating as an outdoor gathering for mental health practices more than anything, and it’s been really incredible." </p> <p>The classes, which initially attracted a few people, has gained a bit of traction with around 50 to 80 regular attendees. </p> <p>Hilmer encourages her attendees to leave a donation and provides free hot drinks and a live musician at the biweekly sessions. </p> <p>Because of its popularity, the council have classified <em>Feel Good Flows </em>as a commercial event, as the classes exceed the number of people covered by Hilmer's personal training license, and she was ordered to pay $400 a session. </p> <p>Hilmer was also given the option to cap the sessions at 15 people a time, but she said that "this isn't an option" as “many vulnerable people” rely on the service.</p> <p>With Hilmer having to pay three months upfront to keep classes running, the total adds up to $10,000, and locals are furious. </p> <p>"Another pathetic decision by useless bureaucrats,” one wrote on social media. </p> <p>“This council is being very mean spirited. Leave her alone!!”</p> <p>“Keep on going love don’t bow to the council,” a third added. </p> <p>Despite the outrage and being asked to pay to host her free yoga sessions, Hilmer remains positive. </p> <p>“I don’t want to fight,” she said.</p> <p>“The council can be the solution”.</p> <p>Port Phillip Mayor Heather Cunsolo replied saying that while she was "delighted" to see so many taking part in yoga sessions, "the business needs to adhere to its Personal Training Licence" to "ensure our popular public spaces remain available, safe and enjoyable for everyone." </p> <p>“We encourage Feel Good Flows to look at hosting additional yoga sessions on the foreshore to support its growing popularity," the <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Port Phillip </span><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">mayor said. </span></p> <p>“Other businesses operating along the foreshore pay a licence fee for the use of public open space and adhere to the 15 person limit per session.</p> <p>"These capacity limits help provide fair access for many businesses operating with a Personal Training Licence, while minimising any potential disruption for visitors to our foreshore." </p> <p>She added that she has been in contact with  Feel Good Flows, and are happy to discuss details further. </p> <p>"If the petition is sent to Council the matter will be heard in the Council Chamber.”</p> <p><em>Images: Instagram</em></p>

<p dir="ltr">As the season changes, so do our healthcare needs as many people struggle with irritating allergies. </p> <p dir="ltr">With cooler temperatures, dry air and an increase in pollen often being synonymous with autumn and spring, for many people, leaving the house means having irritated eyes. </p> <p dir="ltr">Luckily, leading Ophthalmologist, Dr. Jacqueline Beltz has shared her essential tips for eye care during autumn with OverSixty, giving you the opportunity to enjoy the change of seasons without jeopardising your vision. </p> <p dir="ltr"><strong>1. Keep your sunglasses handy</strong></p> <p dir="ltr">While the sun is usually not as intense in autumn as it is during summer, Dr Beltz says that using sunglasses can benefit your eyes in many ways. </p> <p dir="ltr">“ Not only do they shield your eyes from harmful UV rays, but they also guard against wind and debris,” she said. </p> <p dir="ltr"><strong>2. Increase your lubricant eye drops</strong></p> <p dir="ltr">Dr Beltz said, “The drop in temperature and the dryer air can contribute to discomfort and dryness in your eyes, so consider increasing the use of lubricant eye drops to keep your eyes moist and comfortable.”</p> <p dir="ltr">By keeping up your eye drops in autumn, you can prevent further damage to your eyes in the long run. </p> <p dir="ltr"><strong>3. Clean your eyelashes daily</strong></p> <p dir="ltr">According to Dr Beltz, keeping up with good health and hygiene along the eyelid margins is essential, especially during the autumn months. </p> <p dir="ltr">“Cleanse your lashes daily and use a warm compress to optimise the quality of your tear film. This helps in preventing irritation and supports overall eye health.”</p> <p dir="ltr"><strong>4. Consider a humidifier</strong></p> <p dir="ltr">To ensure a more comfortable environment for your eyes, Dr Beltz recommends adding moisture to the air can help alleviate dry eyes.</p> <p dir="ltr">She said, “Combat the dry indoor air by using a humidifier in your room, especially while you sleep.”</p> <p dir="ltr"><strong>5. Be proactive with allergies</strong></p> <p dir="ltr">If you are prone to allergies, Dr Beltz said it's best to always be prepared ahead of time. </p> <p dir="ltr">“Autumn allergies are a reality, with triggers like pollen, mould, and dust prevalent during this season,” she said. </p> <p dir="ltr">“If you experience red, itchy, or swollen eyes, consider antihistamine eye drops. Keep your hands clean and avoid rubbing your eyes.”</p> <p dir="ltr"><strong>6. Revitalise your eye makeup</strong></p> <p dir="ltr">While replacing your eye makeup is important all year around, the addition of allergens makes it even more important to Change mascara and non-cleanable products like liquid eyeliner at least every three months. </p> <p dir="ltr">“Especially if you have sensitive eyes, makeup products can harbour bacteria, leading to increased eye irritation.”</p> <p dir="ltr">“Refreshing your eye makeup products to options that are designed to be better suited for dry eyes or eye sensitivity.”</p> <p dir="ltr">If you are <a href="https://oversixty.com.au/lifestyle/beauty-style/embracing-the-art-of-beauty-without-compromise">prone to sensitive eyes</a>, consider trying the OKKIYO <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara#xd_co_f=NzdiNzdlNTctNTA1MS00NTBkLWE1MGEtNjRkMGE2OTI1N2Vj~">Prioriteyes Mascara</a>, which was developed by Dr Beltz to prioritise both style and eye health.</p> <p dir="ltr">While these tips for eye health can seem simple and seemingly unimportant, Dr Beltz assures that by following these tips, you will make a world of difference for your eye health overall. </p> <p dir="ltr">She said, “Implementing these simple tips can make a significant difference in keeping your eyes comfortable and vibrant throughout the season.”</p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

Eye-watering price tag for "remarkable" first class Titanic menu

<p>A first class dinner menu from the Titanic has been found and sold at an auction in England for £84,000 (around $162,000 AUD) on November 11. </p> <p>The water-stained menu was dated April 11, 1912 just three days before the ship hit an iceberg, ultimately meeting it's ill-fated end causing over 1500 deaths. </p> <p>Wealthy passengers at the time were spoiled with choice, with oysters, salmon, beef, squab (baby pigeon), spring lamb among other dishes on the menu, and that's not including dessert. </p> <p>Auctioneers Henry Aldridge &amp; Son said it was unclear how the menu made it off the ship intact, but the slight water damage suggests that it was recovered from the body of a victim. </p> <p>The rare artefact, which is over 111 years old belonged to amateur historian Len Stephenson, from Nova Scotia, Canada, who passed away in 2017. </p> <p>No one knew he had it, including his family, who only discovered it after going through his belongings following his death. </p> <p>“About six months ago his daughter and his son-in-law, Allen, felt the time was right to go through his belongings,” auctioneer Andrew Aldridge said. </p> <p>“As they did they found this menu in an old photo album.</p> <p>“Len was a very well thought-of historian in Nova Scotia which has strong connections with the Titanic. The body recovery ships were from Nova Scotia and so all the victims were taken back there.</p> <p>“Sadly, Len has taken the secret of how he acquired this menu to the grave with him.”</p> <p>Stephenson worked at a post office and would talk to people, collect old pictures and write letters for them, which might be how he got the rare artefact. </p> <p>According to the auctioneer, no other first class dinner menus dated April 11, 1912 have been recovered from the titanic making this “a remarkable survivor from the most famous Ocean liner of all time”.</p> <p>“There are a handful of April 14 menus in existence but you just don’t see menus from April 11. Most of them would have gone down with the ship,” Aldridge said. </p> <p>“Whereas with April 14 menus, passengers would have still had them in their coat and jacket pockets from earlier on that fateful night and still had them when they were taken off the ship," he added. </p> <p>A few other items recovered from the Titanic were also sold, including a Swiss-made pocket watch recovered from passenger Sinai Kantor which fetched £97,000 (around $187,000 AUD). </p> <p>A tartan-patterned deck blanket, which was likely used during the rescue operation also sold for £96,000 (around $185,000). </p> <p><em>Images: Henry Aldridge &amp; Son of Devizes, Wiltshire</em></p> <p> </p>

What your family history says about your eyesight

<p>Eye disorders can be caused by many things such as infection and injury but did you know it can also be genetic? We know looking up our family history is important for our health but it’s also vitally important to do so for our eyes. Genetics do play a role in determining your family’s susceptibility to certain eye diseases so it’s a good idea to check your family history as well as record any eye issues you have for future generations.</p> <p>Here are some of the most common hereditary eye conditions. </p> <p><strong>Glaucoma</strong></p> <p>Not all glaucoma is inherited but the most common type, primary open-angle glaucoma, is hereditary. According to the Glaucoma Research Foundation, a family history of glaucoma increases your risk around four to nine times.</p> <p>Coupled with the fact glaucoma is much more common as you age, it’s a good idea to get your eyes checked regularly. Glaucoma can lead to the reduction in peripheral vision and even blindness. Signs include bulging eyes, excessive tearing and abnormal sensitivity to light.</p> <p><strong>Age-related macular degeneration</strong></p> <p>Scientist have found that genetics may contribute to the risk of having macular degeneration but it’s not always the case. Some people never develop it even though both parents may have it while others get it even though there is no family history. The current research shows that genetics contribute to macular degeneration anywhere from 40 to 70 percent.</p> <p>However, whether you have a family history or not it’s important to get your eyes checked as age-related macular degeneration is the leading cause of vision loss in people aged 50 and over. </p> <p><strong>Colour blindness</strong></p> <p>A misnomer as people are not ‘blind’ but colour vision deficient. People who are colour blind usually cannot distinguish between certain colours such as red and green. Inherited colour blindness is common in men with women rarely affected. There is no treatment and most people adjust to the condition.</p> <p><strong>Retinitis pigmentosa</strong></p> <p>A mutated gene causes the retina to degenerate which can lead to night blindness and vision loss. Most cases are inherited and it usually appears in childhood but vision loss doesn’t occur until later in life. There is unfortunately no cure and no treatments but researchers are making significant progress in identifying the genes that cause retinitis pigmentosa.</p> <p><strong>Achromatopsia</strong></p> <p>An inherited condition (only if both parents have the recessive gene) that affects 1 in 33,000 people. The condition is associated with decreased vision, sensitivity to light and colour blindness.</p> <p><strong>Optic atrophy</strong></p> <p>Optic atrophy may be inherited or caused by brain trauma, inflammation, degenerative disorders, haemorrhage or tumour. The breakdown of the optic nerve causes vision loss. </p> <p><em>Image credits: Getty Images </em></p>
