New $1m reward for cold case murder of three children

A new $1 million reward is being offered for information about each of the murders of three First Nations children around 34 years ago. Four-year-old Evelyn Greenup, Clinton Speedy-Duroux, 16, and Colleen Walker-Craig, 16, disappeared from Bowraville, a town in northern NSW over a five-month period from September 1990. Evelyn and Clinton's remains were found in nearby bushland, but Colleen's have never been found. The murders were initially investigated separately before being linked by the homicide squad. Now, after various appeals over the decades, NSW Police have issued a re-appeal for information into the murders, with a particular focus on locating the remains of Colleen. “A $1 million reward for information that leads to the arrest and conviction of the person or persons responsible for each of the children’s murder remains in place, as well as for information leading to the location and recovery of Colleen’s remains,” NSW Police said on Monday. Detectives are also going to be spending the week in Bowraville to speak to locals who may have information about the children's deaths. A man, who can't be named for legal reasons, was acquitted of Clinton's murder in 1994, and Evelyn's murder in 2006. The case was the subject of two police investigations, multiple trials, a coronial inquest, and a parliamentary inquiry. In 2018, the government tried to convince the NSW court of criminal appeal that there was fresh and compelling evidence – related to the disappearance of Colleen – in attempt to overturn the two acquittals and instead have a new single trial on three murder charges. However, the court refused to grant special leave to the NSW government to appeal against the decision. In 2019, hundreds protested in front of the gates of the Court of Appeal when a retrial was denied. Images: 7pm TV News NSW/ ABC News

I have a stuffy nose, how can I tell if it’s hay fever, COVID or something else?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/deryn-thompson-1449312">Deryn Thompson</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Hay fever (also called allergic rhinitis) affects <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/national-health-survey-state-and-territory-findings/latest-release">24%</a> of Australians. <a href="https://www.allergy.org.au/patients/allergic-rhinitis-hay-fever-and-sinusitis/allergic-rhinitis-or-hay-fever">Symptoms</a> include sneezing, a runny nose (which may feel blocked or stuffy) and itchy eyes. People can also experience an itchy nose, throat or ears. But COVID is still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">spreading</a>, and <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">other viruses</a> can cause cold-like symptoms. So how do you know which one you’ve got? <h2>Remind me, how does hay fever cause symptoms?</h2> <a href="https://www.allergy.org.au/hp/papers/allergic-rhinitis-clinical-update">Hay fever</a> happens when a person has become “sensitised” to an allergen trigger. This means a person’s body is always primed to react to this trigger. Triggers can include allergens in the air (such as pollen from trees, grasses and flowers), mould spores, animals or house dust mites which mostly live in people’s mattresses and bedding, and feed on shed skin. When the body is exposed to the trigger, it produces IgE (immunoglobulin E) antibodies. These cause the release of many of the body’s own chemicals, including histamine, which result in hay fever symptoms. People who have asthma may find their asthma symptoms (cough, wheeze, tight chest or trouble breathing) worsen when exposed to airborne allergens. Spring and sometimes into summer can be the worst time for people with grass, tree or flower allergies. However, animal and house dust mite symptoms usually happen year-round. <h2>What else might be causing my symptoms?</h2> Hay fever does not cause a fever, sore throat, muscle aches and pains, weakness, loss of taste or smell, nor does it cause you to cough up mucus. These symptoms are likely to be caused by a virus, such as COVID, influenza, respiratory syncytial virus (RSV) or a “cold” (often caused by rhinoviruses). These conditions can occur all year round, with some overlap of symptoms: <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&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/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=582&fit=crop&dpr=1 600w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=582&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=582&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=731&fit=crop&dpr=1 754w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=731&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/624085/original/file-20241007-16-xf6euv.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=731&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><a class="source" href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">Natasha Yates/The Conversation</a></figcaption></figure> COVID still <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">surrounds</a> us. <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/public+content/sa+health+internet/about+us/health+statistics/surveillance+of+notifiable+conditions/respiratory+infections+dashboard">RSV and influenza</a> rates appear higher than before the COVID pandemic, but it may be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10888990/#:%7E:text=Increases%20in%20RSV%20patient%20volume,with%20an%20RSV%20diagnosis%20occurred">due to more testing</a>. So if you have a fever, sore throat, muscle aches/pains, weakness, fatigue, or are coughing up mucus, stay home and avoid mixing with others to limit transmission. People with COVID symptoms can take a rapid antigen test (<a href="https://www.health.gov.au/sites/default/files/2024-04/coronavirus-covid-19-rapid-antigen-tests.pdf">RAT</a>), ideally when <a href="https://www.cochrane.org/CD013705/INFECTN_how-accurate-are-rapid-antigen-tests-diagnosing-covid-19">symptoms start</a>, then isolate until symptoms disappear. <a href="https://www.mja.com.au/journal/2023/219/11/covid-19-rapid-antigen-tests-approved-self-testing-australia-published">One negative RAT alone</a> can’t rule out COVID if symptoms are still present, so test again 24–48 hours after your initial test if symptoms persist.

But again, a negative test doesn’t rule out the virus. If your symptoms continue, <a href="https://www.tga.gov.au/sites/default/files/2024-02/covid-19-rapid-antigen-self-tests-are-approved-australia-ifu-406813.PDF">test again</a> 24–48 hours after the previous test. <h2>If it’s hay fever, how do I treat it?</h2> Treatment involves blocking the body’s histamine release, by taking antihistamine medication which helps reduce the symptoms. Doctors, nurse practitioners and pharmacists can develop a <a href="https://www.allergy.org.au/images/pc/ASCIA_Allergic_Rhinitis_Treatment_Plan_2024.pdf">hay fever care plan</a>. This may include using a nasal spray containing a topical corticosteroid to help reduce the swelling inside the nose, which causes stuffiness or blockage. Nasal sprays need to delivered <a href="https://allergyfacts.org.au/are-you-using-your-nasal-spray-correctly/">using correct technique</a> and used over several weeks to work properly. Often these sprays can also help lessen the itchy eyes of hay fever. Drying bed linen and pyjamas inside during spring can <a href="https://www.allergy.org.au/patients/allergy-treatments/allergen-minimisation">lessen symptoms</a>, as can putting a <a href="https://www.nps.org.au/consumers/managing-hay-fever">smear of Vaseline</a> in the nostrils when going outside. Pollen sticks to the Vaseline, and gently blowing your nose later removes it. People with asthma should also have an <a href="https://asthma.org.au/manage-asthma/asthma-action-plan/">asthma plan</a>, created by their doctor or nurse practitioner, explaining how to adjust their asthma reliever and preventer medications in hay fever seasons or on allergen exposure. People with asthma also need to be <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/thunderstorm-asthma">alert for thunderstorms</a>, where pollens can burst into tinier particles, be inhaled deeper in the lungs and cause a severe asthma attack, and even death. <h2>What if it’s COVID, RSV or the flu?</h2> Australians aged 70 and over and others with underlying health conditions who test positive for COVID are <a href="https://www.healthdirect.gov.au/covid-19/medications#at-home">eligible for antivirals</a> to reduce their chance of severe illness. Most other people with COVID, RSV and influenza will recover at home with rest, fluids and paracetamol to relieve symptoms. However some groups are at greater risk of serious illness and may require additional treatment or hospitalisation. For <a href="https://www.health.nsw.gov.au/Infectious/factsheets/Pages/respiratory-syncytial-virus.aspx">RSV</a>, this includes premature infants, babies 12 months and younger, children under two who have other medical conditions, adults over 75, people with heart and lung conditions, or health conditions that lessens the immune system response. For influenza, people at <a href="https://www.health.nsw.gov.au/Infectious/Influenza/Pages/at-risk.aspx">higher risk</a> of severe illness are pregnant women, Aboriginal people, people under five or over 65 years, or people with long-term medical conditions, such as kidney, heart, lung or liver disease, diabetes and decreased immunity. If you’re concerned about severe symptoms of COVID, RSV or influenza, consult your doctor or call 000 in an emergency. If your symptoms are mild but persist, and you’re not sure what’s causing them, book an appointment with your doctor or nurse practitioner.

“Witnesses” in William Tyrrell case turned away by police

Several potential witnesses who claim to have spotted William Tyrrell after he went missing in 2014 allege that they were dismissed by police, with phone calls to Crime Stoppers also going unanswered. One woman claims to have seen the child near Uluru one year after he was reported missing, with another four people claiming they had valuable information that was ignored by authorities. As <a href="http://news.com.au/">news.com.au</a> continues their investigative podcast into Tyrrell’s disappearance, the podcast spoke to the witnesses who were allegedly ignored by police, as one woman said she “felt sick” after being dismissed when trying to report another possible sighting of William. A third possible witness said he was “p***ed off with Crime Stoppers not taking me seriously”. After the then three-year-old disappeared from Kendall on the mid North coast of New South Wales, NSW Police were inundated with information. In the following two years, there were around 2,800 calls to Crime Stoppers, and more than 1,000 possible sightings of William, with many of these tips being followed up at the time. While speaking with the podcast, one potential witness, Lois Barry, believed she saw William travelling with a group of four adults and several young children when she was on a trip to Australia’s red centre in 2015. She said she had an encounter with a blonde woman at a petrol station in Marla, South Australia, who told Ms Barry she was from the east coast of NSW. As soon as Ms Barry went into a free cubicle, she claimed the woman said: “You can come out now, Will.” Ms Barry said she saw the group again at a campsite later that night, and recognised one of the group from media reports of William’s disappearance. The boy was younger than the other children in the group and she felt he was being “hidden” by them, she said. One of the adults with the group was the blonde woman, as Ms Barry took a photo of the woman and noted down the registration numbers of the vehicles in which the group were travelling. Ms Barry told news.com.au she tried to report her potential sighting at the time by visiting a local police station, only to be cut off by an officer who said he was busy, and told her “don’t worry about it”. She then called Crime Stoppers “two or three times” to report what she had seen, but she said, “Crime Stoppers rang me back and said it was nothing.” Ms Barry said she has never heard directly from police. “For all those years … that was just eating at me,” she said, breaking down as she described her fears of what might have happened to William. Another potential witness, Richard Brindle, said he contacted Crime Stoppers shortly after police appealed for information about two cars “parked strangely with the driver windows down” outside the house where William was reported missing. Despite multiple reports to Crime Stoppers, Mr Brindle said he never heard back. “I had some fresh information at the time, and I rang Crime Stoppers twice. And they must have thought I was some nut job or whatever,” he said. “I was a bit p***ed off with Crime Stoppers not taking me seriously. It’s very serious stuff, it’s a boy’s life. And they didn’t even bother to interview me. I thought, ‘What a joke. No one seems to care’.” Image credits: NSW Police

I’ve recovered from a cold but I still have a hoarse voice. What should I do?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yeptain-leung-1563747">Yeptain Leung</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Cold, flu, COVID and <a href="https://theconversation.com/rsv-is-everywhere-right-now-what-parents-need-to-know-about-respiratory-syncytial-virus-208855">RSV</a> have been <a href="https://www.abc.net.au/news/2024-06-21/flu-whooping-cough-rsv-cases-up-as-covid-cases-unkown/104002964">circulating across Australia this winter</a>. Many of us have caught and recovered from <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">one of these</a> common upper respiratory tract infections. But for some people their impact is ongoing. Even if your throat isn’t <a href="https://theconversation.com/sore-throats-suck-do-throat-lozenges-help-at-all-184454">sore</a> anymore, your voice may still be hoarse or croaky. So what happens to the voice when we get a virus? And what happens after? Here’s what you should know if your voice is still hoarse for days – or even weeks – after your other symptoms have resolved. <h2>Why does my voice get croaky during a cold?</h2> A healthy voice is normally clear and strong. It’s powered by the lungs, which push air past the vocal cords to make them vibrate. These vibrations are amplified in the throat and mouth, creating the voice we hear. The vocal cords are two elastic muscles situated in your throat, around the level of your laryngeal prominence, or Adam’s apple. (Although everyone has one, it tends to be more pronounced in males.) The vocal cords are small and delicate – around the size of your fingernail. Any small change in their structure will affect how the voice sounds. When the vocal cords become inflamed – known as laryngitis – your voice will sound different. Laryngitis is a common part of upper respiratory tract infections, but can also be caused through misuse. <figure class="align-center "><img src="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&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/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=366&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=366&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=366&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=460&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=460&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=460&fit=crop&dpr=3 2262w" alt="Two drawn circles comparing normal vocal cords with inflamed, red vocal cords." /><figcaption>Viruses such as the common cold can inflame the vocal cords. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458117">Pepermpron/Shutterstock</a></figcaption></figure> Catching a virus triggers the body’s defence mechanisms. White blood cells are recruited to kill the virus and heal the tissues in the vocal cords. They become inflamed, but also stiffer. It’s harder for them to vibrate, so the voice comes out hoarse and croaky. In some instances, you may find it hard to speak in a loud voice or have a reduced pitch range, meaning you can’t go as high or loud as normal. You may even “lose” your voice altogether. Coughing can also make things worse. It is the body’s way of trying to clear the airways of irritation, including your own mucus dripping onto your throat (<a href="https://www.health.harvard.edu/staying-healthy/treatments-for-post-nasal-drip">post-nasal drip</a>). But coughing slams the vocal cords together with force. Chronic coughing can lead to persistent inflammation and even thicken the vocal cords. This thickening is the body trying to protect itself, similar to developing a callus when a pair of new shoes rubs. Thickening on your vocal cords can lead to physical changes in the vocal cords – such as developing a growth or “nodule” – and further deterioration of your voice quality. <figure class="align-center "><img src="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&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/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=376&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=376&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=376&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=473&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=473&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=473&fit=crop&dpr=3 2262w" alt="Diagram compares healthy vocal cords with cords that have nodules, two small bumps." /><figcaption>Coughing and exertion can cause inflamed vocal cords to thicken and develop nodules. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458126">Pepermpron/Shutterstock</a></figcaption></figure> <h2>How can you care for your voice during infection?</h2> People who use their voices a lot professionally – such as teachers, call centre workers and singers – are often desperate to resume their vocal activities. They are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478078/">more at risk</a> of forcing their voice before it’s ready. The good news is most viral infections resolve themselves. Your voice is usually restored within five to ten days of recovering from a cold. Occasionally, your pharmacist or doctor may prescribe cough suppressants to limit additional damage to the vocal cords (among other reasons) or mucolytics, which break down mucus. But the most effective treatments for viral upper respiratory tract infections are hydration and rest. Drink plenty of water, avoid alcohol and exposure to cigarette smoke. <a href="https://www.healthdirect.gov.au/laryngitis#:%7E:text=You%20can%20help%20your%20voice%20recover%20by%3A%201,avoid%20nasal%20decongestants%20%28these%20make%20your%20throat%20drier%29">Inhaling steam</a> by making yourself a cup of hot water will also help clear blocked noses and hydrate your vocal cords. Rest your voice by talking as little as possible. If you do need to talk, don’t whisper – this <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199704001730">strains the muscles</a>. Instead, consider using “<a href="https://www.instagram.com/reel/C0d-oNIMM1y/">confidential voice</a>”. This is a soft voice – not a whisper – that gently vibrates your vocal cords but puts less strain on your voice than normal speech. Think of the voice you use when communicating with someone close by. During the first five to ten days of your infection, it is important not to push through. Exerting the voice by talking a lot or loudly will only exacerbate the situation. Once you’ve recovered from your cold, you can speak as you would normally. <h2>What should you do if your voice is still hoarse after recovery?</h2> If your voice hasn’t returned to normal after <a href="https://www.healthdirect.gov.au/laryngitis">two to three weeks</a>, you should seek medical attention from your doctor, who may refer you to an ear nose and throat specialist. If you’ve developed a nodule, the specialist would likely refer you to a speech pathologist who will show you how to take care of your voice. Many nodules can be <a href="https://britishvoiceassociation.org.uk/voicecare_vocal-nodules.htm">treated</a> with voice therapy and don’t require surgery. You may have also developed a habit of straining your vocal cords, if you forced yourself to speak or sing while they were inflamed. This can be a reason why some people continue to have a hoarse voice even when they’ve recovered from the cold. In those cases, a speech pathologist may play a valuable role. They may teach you to exercises that make voicing more efficient.

No, your aches and pains don’t get worse in the cold. So why do we think they do?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather. It’s a common idea, but a myth. When we looked at the evidence, <a href="https://www.sciencedirect.com/science/article/pii/S0049017224000337">we found</a> no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains. So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on. <h2>Weather can be linked to your health</h2> The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures <a href="https://pubmed.ncbi.nlm.nih.gov/27021573/">may worsen</a> asthma symptoms. Hot temperatures <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00117-6/fulltext">increase the risk</a> of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease. Many people are also convinced the weather is linked to their aches and pains. For example, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1479-8077.2004.00099.x?casa_token=jvpSbA4szqoAAAAA%3ATyHyGaqXmfevWyuJe6LW_3Pap3IPHC8HSMTl3RN63mFzNO0X7ozQjBb6Bi3yVFuPjqkrf-WlB-J5A1q1">two in every three</a> people with knee, hip or hand osteoarthritis <a href="https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/1471-2474-15-66">say</a> cold temperatures trigger their symptoms. Musculoskeletal conditions affect more than <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions-comorbidity-australia/summary">seven million Australians</a>. So we set out to find out whether weather is really the culprit behind winter flare-ups. <h2>What we did</h2> Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies. We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included. We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry). <h2>What we found</h2> We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis. The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain. In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis. It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather. The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions. Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up. <h2>Why do people blame the weather?</h2> The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain. For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know <a href="https://pubmed.ncbi.nlm.nih.gov/28700451/">prolonged sitting</a>, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. Likewise, changes in mood, often experienced in cold weather, trigger increases in both <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself. Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the <a href="https://link.springer.com/article/10.1186/s12891-018-1943-8">nocebo effect</a>. <h2>What to do about winter aches and pains?</h2> It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather). You can: <ul> <li> become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool </li> <li> lose weight if obese or overweight, as this is linked to <a href="https://jamanetwork.com/journals/jama/article-abstract/2799405">lower levels</a> of joint pain and better physical function </li> <li> keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep <a href="https://www.sciencedirect.com/science/article/pii/S0033350623003359">less well</a> in cold rooms </li> <li> maintain a healthy diet and <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">avoid smoking</a> or drinking high levels of alcohol. These are among <a href="https://ard.bmj.com/content/annrheumdis/82/1/48.full.pdf">key lifestyle recommendations</a> to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with <a href="https://pubmed.ncbi.nlm.nih.gov/36208321/">higher levels</a> of physical function.<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/235117/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, Professor of Musculoskeletal Health, Head of Musculoskeletal Program, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, Rheumatologist and Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

100 cases confirmed in Melbourne's Legionnaires' outbreak

Authorities have confirmed that the number of confirmed cases of Legionnaires' in Melbourne has climbed to 100. Since the first confirmed case on July 26th, two elderly people have died from the illness, after the outbreak was tracked back to a cooling tower in Laverton North, in the city's west. The Department of Health currently investigating the outbreak, as another 10 suspected cases being closely monitored. Most of the cases are in adults aged over 40 and many have required hospitalisation, with a number of cases then requiring admission to intensive care after they developed severe community acquired pneumonia. Victoria’s chief health officer, Dr Clare Looker said authorities believe people were exposed to the virus between July 5th and July 20th, and presented with symptoms from the 15th. “Recent weather patterns could explain the wider than usual spread of legionella bacteria with this outbreak,” she said. Common symptoms of legionnaires’ include chills, cough, fever, headache and muscle aches and pains, while other atypical symptoms may include nausea, vomiting, diarrhoea and confusion. Legionella is commonly associated with plumbing fixtures, humidifiers, air scrubbers and air conditioners but can become severe when it begins in a major water source. Image credits: Shutterstock

Major update in case against accused Russian spies

Accused Russian spies Kira and Igor Korolev have had their assets seized by the AFP as the investigation into their espionage-related offences continues. Kira, an Australian Defence Force army private, and her husband became the first Australians to be charged with espionage since 2018 after allegedly working together to leak state secrets to Russia. The couple were <a href="https://oversixty.com.au/finance/legal/aussie-couple-arrested-and-charged-with-spying-for-russia" target="_blank" rel="noopener">arrested</a> in July in their Brisbane home and were charged with one count each of preparing for an espionage offence, which carries a maximum penalty of 15 years’ imprisonment. Now, as the investigation into their activities continue, the AFP have sought an order to confiscate the apartment, assets and financed. The AFP-led Criminal Assets Confiscation Taskforce (CACT) is seeking to confiscate the married couple’s apartment and financial savings under the Proceeds of Crime Act 2002 (Commonwealth). Last Friday, the Queensland Supreme Court made restraining orders over property owned by the couple, valued in excess of $550,000. The property subject to the restraining orders includes a Brisbane apartment owned by the couple, multiple bank accounts, and the superannuation funds acquired by Ms Korolev during her employment with the ADF. According to authorities, Kira, 40, undertook non-declared travel to Russia while on leave from the ADF and instructed her 62-year-old husband Igor, who remained in Australia, to log into her work account from their Brisbane home. The couple allegedly unlawfully accessed, copied and disseminated information from the Department of Defence computer systems that concerned the national security of Australia. The couple have not entered pleas to the charge against them and remain in custody on remand, and are next scheduled to appear in court in September. Image credits: Facebook

Major breakthrough solves 44-year-old cold case

A decades-old mystery surrounding a human jawbone found on Umina Beach on the NSW Central Coast has been solved, thanks to advances in DNA analysis techniques. The jawbone, discovered by a dog walker in June 2020, was recently identified as belonging to a teenager who tragically drowned nearly half a century ago. Police announced the breakthrough in a statement on Sunday, revealing that the jawbone belonged to Henry Coleman, a 17-year-old who died in an accidental drowning on the Central Coast in August 1980. The remains, though blackened, were remarkably well-preserved and still contained some teeth when found on the beach. Detectives initially determined the remains were human and male, but extensive traditional inquiries failed to establish an identity. It wasn't until March 2023 that a major breakthrough was made using new DNA analysis technology. This technology, which combines advanced DNA analysis with traditional genealogy, allowed investigators to use commercial DNA databases to identify suspects and unknown remains. The key to solving the case was a genetic link to a possible living relative. A voluntary DNA sample from this relative confirmed the jawbone belonged to Coleman. The young man had been laid to rest in the 1980s, but it was not known at the time that part of his jaw was missing. Detective Inspector Ritchie Sim highlighted the importance of public participation in resolving missing persons cases. "This investigation showcases the importance of DNA testing in missing person cases," he said. "Without the combined efforts of our detectives, scientists, and analysts, we would not have been able to return these remains to their resting place and provide closure to Mr Coleman’s family." Sim went on to urge those who have reported a family member missing to police, and who have the Event number, to provide their DNA at a local police station. "Just like in Mr Coleman’s case, your relationship with the missing person can be several generations apart," he added. Images: 7News

Ted Bundy cold case finally solved after 51 years

In March 1973 the half-naked body of Ann Woodward was found brutally murdered on the floor inside the pub that she owned with her husband. The 46-year-old mother's body was discovered between two pool tables, with her shirt unbuttoned and pants used to strangle her. Her murder has haunted the small US desert town of Moab, Utah for over half a century. While police were never able to find her killer, they believed Ted Bundy was the likely culprit, as he had raped and killed multiple women in the area around the time of her death. While Bundy admitted to thirty murders, his real victim count is unknown. However, they had not been able to prove that he was the culprit due to a lack of evidence, so police assumed she was just another one of his unnamed victims. 25 other men, including Douglas Keith Chudomelka, had also been of interest to police after the crime, as witnesses spotted Chudomelka's sedan parked near the victims car on the night of the murder. However, when Chudomelka was interviewed the next day, he denied being at the bar, and insisted that he was at a nearby tavern. His girlfriend at the time, a woman named Joyce, also backed his statement and said he was home at the time of the murder on March 2, 1973. A few months later, Chudomelka was arrested on a domestic violence charge, with an angry Joyce claiming he had been the one who killed Ann Woodward, but she soon retracted her statement. With no new leads, the case went cold, but forward-thinking Police Chief Melvin Dalton, decided to keep DNA evidence from both the victim and all potential suspects anyways, in hopes that one day the right technology would be used to identify the killer. In 2006, Dalton reopened the case, but had no luck until September 2023, when Detective Jeremy Dexler decided to uncover the two boxes of evidence collected from the initial investigation and send it to the crime lab. The DNA evidence had sat at the Moab police department's storage units for over 50 years and was not easy to locate as it had been moved to another building. The evidence was crucial in solving the cold case. When results from the crime lab came back at the end of May 2024, they confirmed that a substantial amount of Chudomelka’s DNA was on the inside of Ann’s pants and on all of the buttons of her shirt. This was enough to confirm that Chudomelka was the one responsible for Ann Woodward's murder. He was 36 when he committed the crime. Chudomelka was not known to the victim, but Detective Drexler believes that he may have played a game of poker with Ann when he visited the pub, and may have been angry at her for beating him. He added that it could have also been a crime of opportunity rather than rage as he had a violent history. Detective Drexler praised Dalton's forward-thinking for being the reason why they solved the case. “This case hinged on the hair Dalton pulled in 1973,” Drexler said. “I have no idea how he knew that we would be able to do that today. Dalton made this case very easy for us in that aspect.” Chudomelka passed away in 2002 at the age of 67 without ever paying for his crime, but County Lawyer Stephen Stocks believes that if he was still alive, he would've been found guilty of murder. “I hope today brings some closure to the family,” he said. “I truly believe had this been presented to a jury, Chudomelka would have been found guilty beyond reasonable doubt for the murder of Ann Woodward.” Images: Moab Police Department

Southern Australia is freezing. How can it be so cold in a warming climate?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> People living in southern Australia won’t have failed to notice how cold it is. Frosty nights and chilly days have been the weather for many of us since the start of July. As winter continues, we are left wondering how unusual the cold is and whether we can expect several more months of this. Warmer conditions are in the forecast but winter has a long way to go. Further cold snaps could occur. Cold conditions have been in place across southern Australia for the past few days. Temperatures have fallen below zero overnight in many places. It’s not just the nights that have been cold. Maximum temperatures have also been below or well below average across most of the country. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&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/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=412&fit=crop&dpr=1 600w, https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=412&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=412&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=518&fit=crop&dpr=1 754w, https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=518&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/604809/original/file-20240704-20-l50kpt.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=518&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Maximum temperatures have been below average across most of the continent since the last day of June. <a class="source" href="http://www.bom.gov.au/jsp/awap/temp/index.jsp">Bureau of Meteorology</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> <h2>What’s causing the cold?</h2> A <a href="http://www.bom.gov.au/australia/charts/synoptic_col.shtml">persistent and strong high-pressure system</a> has been hanging around over southeast Australia. The atmospheric pressure was so high it approached the Australian record of 1,044.3 hPa set on June 7 1967. An <a href="https://www.abc.net.au/news/2024-07-04/australias-highest-air-pressure-recorded-weather/104055462">initial observation</a> of a new record has since been disregarded, but nonetheless this is an exceptional, near-record high-pressure pattern. This high-pressure system has kept the weather dry but clear nights have allowed strong cooling of the land surface. The long nights and short days of early July mean that temperatures struggle to rise during the day and can fall quickly in the evenings. In winter we expect cold weather across most of Australia and occasional cold snaps that bring widespread frosty and icy conditions. However, this current cold weather is pretty unusual and we are seeing some records fall. Notably, Tasmania has had its <a href="https://www.weatherzone.com.au/news/tasmanias-2ndcoldest-night-on-record/1889603">lowest July temperature on record</a> and the second-lowest minimum temperature for any time of year with –13.5°C at Liawenee in central Tasmania early on Thursday morning. While Tasmania has produced the most remarkable records, the cold conditions have been unusual elsewhere too. Adelaide recorded its lowest temperature in 18 years on Wednesday morning. And many suburbs of Melbourne experienced a sub-zero night and consecutive nights of <a href="https://www.metoffice.gov.uk/weather/learn-about/weather/types-of-weather/frost-and-ice/frost">ground frost</a>. <h2>Winters are warming but cold spells still occur</h2> As the world is warming, it might seem surprising we can still break cold records. Indeed, across Australia <a href="http://www.bom.gov.au/cgi-bin/climate/change/timeseries.cgi?graph=tmean&area=aus&season=0608&ave_yr=0&ave_period=6190">winters have been warming</a>. The <a href="http://www.bom.gov.au/cgi-bin/climate/change/extremes/trendmaps.cgi?map=CN05&period=1950">frequency</a> and <a href="http://www.bom.gov.au/cgi-bin/climate/change/extremes/trendmaps.cgi?map=TNmn&period=1950">intensity</a> of very low temperatures have been decreasing over the past few decades. We also see many more hot records than cold records being set in Australia and around the globe. This is <a href="https://theconversation.com/why-hot-weather-records-continue-to-tumble-worldwide-86158">due to human-caused climate change</a>. However, when we have the right weather conditions, cold records are still occasionally broken locally. As we continue to warm the planet, it’s getting harder for us to find cold records, particularly over larger regions or longer time periods. While we still see record cold temperatures at individual weather stations, we won’t see another cold record in the global average temperature and probably not even in the Australian average temperature. As this week shows, we still occasionally get daily cold records in the current climate. But it’s much harder to get record cold months, and record cold years at a given location are almost impossible. As we average weather conditions across locations or over time, the climate change signal becomes clearer over background weather variability. It makes new cold records much less likely to occur. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&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/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=426&fit=crop&dpr=1 600w, https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=426&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=426&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=536&fit=crop&dpr=1 754w, https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=536&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/605048/original/file-20240704-21-7ep1rt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=536&fit=crop&dpr=3 2262w" alt="A graphic showing the increase in annual average temperature for Australia from 1910 to 2023" /></a><figcaption>The climate change signal is becoming clearer as Australia’s annual average temperature continues to increase with each decade, widening the difference from the long-term mean. <a class="source" href="http://www.bom.gov.au/climate/current/annual/aus/#tabs=Temperature">Bureau of Meteorology</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> <h2>How much longer will this cold snap last?</h2> Southern Australia is experiencing a cold snap at close to the coldest time of year. It’s not long after the winter solstice, when we experience the longest night of the year. We still have a few more cold days and nights ahead in parts of southeastern Australia. By early next week, the forecast suggests <a href="http://www.bom.gov.au/australia/charts/viewer/index.shtml">warmer conditions</a> will return as the high-pressure system moves east and winds turn northerly. The outlook for the rest of winter points firmly to <a href="http://www.bom.gov.au/climate/outlooks/#/overview/summary">above-average daytime and night-time temperatures</a>. This is partly because a historical average (1981–2018) is used and warming since then means above-average temperatures are going to happen most of the time. In any winter, Australia has cold outbreaks. So, even if the next few months are likely to be warmer than normal, we should expect a few cold days and nights at some point.

Flight attendant reveals the unexpected reason why it's so cold on planes

When it comes to packing essentials in your carry-on for your next flight, many people add a jumper, extra socks, or even their own blanket to their bags. Because one thing’s for sure: you’ll probably be cold on your flight. But have you ever stopped to think of the reason why the cabin of a plane is so cold? According to a Canadian flight attendant, it's to do with keeping you feeling good. Vanessa Settimi told Reader's Digest that a cooler cabin helps passengers who are prone to fainting or have motion sickness during turbulence. She also clarified that despite what travellers may think, cabin crew don’t have control over the cabin temperature. "Temperature in the cabin is controlled by the pilots. Even though travellers often ask to get the temperature turned up during flights, it is kept on the cooler side." She went on to say that the key to staying warm on your next flight is bringing extra layers. "Now this might just be the flight attendant in me," says Settimi, "but you will never catch me flying as a traveller in sandals and a tank top!" Image credits: Shutterstock

New development in Samantha Murphy murder case

In a significant turn of events, Patrick Stephenson, the man charged with the murder of Samantha Murphy, has secured high-profile legal representation. Samantha Murphy, a beloved mother of three, disappeared after going for a run on Sunday, February 4. Despite extensive searches near her home in Ballarat, her body has not been found. Patrick Orren Stephenson, 22, was charged with the 51-year-old’s murder in March. He has now enlisted the services of renowned solicitor Paul Galbally from Melbourne law firm Galbally O’Bryan. Galbally is recognised for his expertise in handling some of the country’s largest and most intricate criminal cases, with previous clients including the late Catholic Cardinal George Pell, who was initially convicted but later acquitted of historic child sex charges. In a major breakthrough in the investigation, <a href="https://www.oversixty.com.au/finance/legal/major-update-in-search-for-samantha-murphy-s-body" target="_blank" rel="noopener">police discovered Samantha Murphy’s missing phone</a> last Wednesday. The phone, found in a dam about 19km south of the Murphy family home, is in near-perfect condition despite being submerged in mud. Forensic testing on the phone is ongoing and could provide crucial information about her final movements. Samantha's husband, Mick, confirmed the phone belonged to his wife immediately upon being informed by the police. The recovery of the phone was a moment of subdued celebration for the officers, with footage from the ABC showing them hugging and shaking hands at the discovery site. Cybersecurity expert Nigel Phair called the phone’s recovery a “game changer” for the investigation. “The physical properties of the phone will obviously be damaged," he said. "But what’s behind it, those ones and zeros of data, will be retrievable.” Samantha Murphy was last seen leaving her Eureka Street home in Ballarat at around 7 am for a 14km run through the Woowookarung Regional Park. Police believe she reached the Mount Clear area, adjacent to the park, about an hour after leaving home. Subsequent searches by police and volunteers have yet to locate any trace of her. In February, a large group of volunteers gathered at Ballarat’s Eureka Stockade Memorial Park to search the surrounding bushland, using metal detectors and even a sniffer dog. Later, police conducted a targeted search of Buninyong Bushland Reserve, employing specialist units including mounted officers, the dog squad and motorcyclists. This search was driven by intelligence from multiple sources. Patrick Stephenson, who has not yet entered a plea, is scheduled to appear at Ballarat Magistrates’ Court on August 8, facing charges of Samantha Murphy’s murder. The case continues to unfold as investigators hope the data recovered from Samantha's phone will provide new leads and bring them closer to solving this tragic mystery. Images: Supplied / Facebook

Why a cold beer is best – chemically speaking

A quiet moment in a bar has led two researchers to study how alcohol tastes at different temperatures. No, this is real science. <div class="copy"> “Two years ago, Xiaotao Yang and I were drinking beer together. He had just finished his doctorate degree thesis and asked me, ‘what should we do next?’” says Lei Jiang, lead author of a new study <a href="https://doi.org/10.1016/j.matt.2024.03.017" target="_blank" rel="noopener">published</a> in the materials science journal Matter. Yang and Jiang are material scientists at the Chinese Academy of Sciences. “At the time, I was a scientific committee member of one of the biggest Chinese alcoholic beverage companies, and I had the idea to ask the question ‘why does Chinese baijiu have a very particular concentration of alcohol, either 38%–42%, 52%–53%, or 68%–75%?’” Baijiu is a clear grain liquor from East Asia. It’s typically distilled from fermented sorghum (a type of grass), though it is also sometimes made from rice, wheat, barley or millet. “Then we decided, let’s try something, so I put a drop of beer on my hand to see the contact angle,” says Jiang. Contact angle is a measure of surface tension. For example, water has a low contact angle which is why it appears bead-like when placed on a surface. Solutions with high <a href="https://cosmosmagazine.com/health/body-and-mind/debunks-vices-alcohol/">alcohol</a> concentration, however, have a higher contact angle meaning they flatten and spread out. Contact angle also reveals how molecules within the droplet interact with each other and the surface below. After plotting the concentration of ethanol (alcohol) against contact angle, the scientists were surprised with what they found. There is no linear relationship between alcohol concentration and contact angle. Instead, increasing the amount of alcohol leads to a series of plateaus and sharp rises in the plot. Further experiments showed that this arises out of the formation of clusters of ethanol and water in the solutions. At low concentrations, ethanol forms pyramid-like structures around the water molecules. At high concentrations, the ethanol molecules arrange end-to-end in a chain. They also found that these structures change depending on temperature. For example, 38%–42% and 52%–53% ethanol solutions have distinct cluster structures at around room temperature, but this difference disappears at higher temperatures, like 40°C. “Although there is only 1% difference, the taste of baijiu at 51% and 52% is noticeably different; the taste of baijiu at 51% is similar to that of lower alcohol content, such as 38%–42%. So, in order to achieve the same taste at a lower alcohol content, the distribution of baijiu products ranges most within the 38%–42% and 52%–53% categories,” says Jiang. The researchers also found that there is an increase in ethanol chains at 5°C in 5% and 11% ethanol solutions – the concentration range of beer – giving it a more “ethanol-like” taste which is generally preferred. “At low temperature, the tetrahedral (pyramid-shaped) clusters become the low concentration amount, and this is why we drink cold beer,” says Jiang. The researchers say their research could help beverage companies produce the best flavour with the lowest alcohol concentration.

Bombshell allegations in murder case of young school girl

The man accused of murdering nine-year-old Charlise Mutten has claimed her mother was the one to pull the trigger. Justin Stein, 33, is facing trial for allegedly murdering Charlise in January 2022 at Mount Wilson, in the Blue Mountains west of Sydney. Nine-year-old Charlise was shot once in the head and once in the back, with her body recovered from a barrel dumped near the Colo River, four days after she was reported missing by her mother. On Monday, Stein formally pleaded not guilty to the charges, and has now alleged it was actually Charlise's mother who killed her and helped stuff her body in a barrel before lying to police. The court heard that Stein was in a relationship with Charlise's mother Kallista Mutten, as the pair met while both serving jail sentences. Both parties struggled with substance abuse, as Kallista had been using ice since she was in her early 20s, while Justin had been undergoing treatment for heroin addiction. Before the alleged murder, Stein and Kallista broke into a neighbour’s home near the Mount Wilson property, taking two firearms, crown prosecutor Ken McKay SC told the jury. Stein initially told police the girl may have been taken by unknown persons, but later told a corrections officer Kallista had shot and killed her daughter and that he had helped dispose of the body. According to Stein’s lawyer, Carolyn Davenport SC, Stein had been inside a shed on the Blue Mountains property when he heard a gunshot, and had gone outside to see Kallista shooting her daughter a second time. At the time of her death, Charlise was living with her grandparents at Tweed Heads, and had flown to Sydney on December 21st with plans to spend Christmas and New Year’s Eve with her mother and Stein.

Brutal cost of Bruce Lehrmann’s failed defamation case

Bruce Lehrmann has been ordered to pay the majority of Network Ten's multi-million dollar legal fees after his failed defamation case. In April, Lehrmann faced a huge loss after the Federal Court found an allegation that he raped Brittany Higgins in a Parliament House office in March 2019 was most likely true, therefore is unable to be defamed for the allegations. The 28-year-old had sued Network Ten for defamation over a February 2021 report on The Project, in which journalist Lisa Wilkinson interviewed Higgins over the rape allegation. Since the defamation case drew to a close, the parties have been in dispute over the legal costs and who should foot what is expected to amount to a sizeable legal bill for the long-running and high-profile case. On Friday afternoon, Justice Michael Lee found in favour of Ten's application for indemnity costs for most of the trial, as Lehrmann is now ordered to pay for the network's and Wilkinson's costs on an ordinary and indemnity basis, but he will not have to pay costs for some affidavits. "In the end, it comes down to the order for costs that best does overall justice in the circumstances," Lee told the court. "On balance, the appropriate exercise of discretion is to make an award that Network Ten recover its costs against Mr Lehrmann on an indemnity basis, except for costs incurred in relation to the statutory qualified privilege defence." In explaining his decision, the judge said he found Lehrmann had defended the criminal charge "on a false basis, lied to police, and then allowed that lie to go uncorrected before the jury". "He wrongly instructed his senior counsel to cross-examine a complainant of sexual assault, in two legal proceedings, including, relevantly for present purposes, this case, on a knowingly false premise," he said. Earlier in the week, the court heard Lehrmann had no financial backers and that his lawyers had agreed they did not need to be paid if he lost the case. The total amount he will have to pay will be determined at a hearing later in May.

"I killed them": Major twist in slain Aussie brothers case

The girlfriend of the man who allegedly killed Perth brothers Callum and Jake Robinson has reportedly "flipped" on her partner, becoming the star witness in the case. Ari Gisel García Cota was arrested earlier this week, along with her partner Jesús Gerardo Garcia Cota and his brother Cristian Alejandro Garcia, after the bodies of the Robinson brothers and their friend were found on Saturday in a desolate section of Santo Tomas in the Baja California region. According to Mexico police, the three men were killed as a result of a failed robbery, after locals attempted to steal the tyres from their pick-up truck. The bodies of the three men were recovered from a 15-metre deep well, with each man having fatal gun shot wounds to the head. In a major twist to the case, prosecutors revealed to court on Wednesday that Ari Gisel García Cota had become a key witness in the case after turning on the "ringleader" of the crime. “She has flipped on the ringleader and the evidence she’s provided to the prosecution will lead this case going forward,” Nine News correspondent Alison Piotrowski, who was in the courtroom, told 2GB’s Ben Fordham on Thursday. “What’s alleged is that Jesús Gerardo was driving her car that night when he went out to that remote campsite. The prosecution is saying what we’ve been talking about for the last couple of days has potentially happened, that the two Aussies and their American friend were ambushed.” Prosecutors allege Jesús Gerardo “killed them, took their tyres, put the tyres on her car and drove back”. When he went back to their house, the court heard he allegedly told Ari Gisel, “I f**ked up three gringos (English-speaking foreigner).” “She said to him, ‘What do you mean by that?’ And he told her, ‘I killed them’, and then showed her the vehicle with Jake, Callum and Jack’s tyres on her car,” Piotrowski said. “Ari was arrested later that day, she had fled to her mother’s house to get away from him. When the officers arrested her they said, ‘You have the right to remain silent’, and she said, ‘I don’t want to be silent, I want to tell you what I know. I’m a victim of domestic violence, I want to protect my four-year-old so let me help you with this case.’ So she has spectacularly turned on him and will now be crucial in this case moving forward.” Piotrowski added that the stunning revelation explained why Mexican officials “have been able to put him behind bars so quickly and also how they found the bodies”. “This conversation that he had with his girlfriend is pretty damning,” she said. So far only Jesús Gerardo Garcia Cota has been charged in connection with the deaths of the three men, and only with forced kidnapping, while Ari Gisel García Cota and Cristian Alejandro Garcia have only been charged with drug possession. Piotrowski said the kidnapping charges may not be upgraded to murder until the next court hearing, although the judge has more questions about how the three men were killed. “The judge did say that he can’t understand how one sole person could have done this, essentially kidnap and kill three men and take their tyres, it seems like too much,” she said. “He suggested that the prosecution needed to look into more suspects, that they needed to broaden their investigation because it couldn’t have been done by one man alone.” Image credits: Instagram / State Commission of the Penitentiary System of Baja California

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time. Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<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/221709/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, Health Sciences Assistant Professor of Clinical Veterinary Medicine, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Huge reward to help solve cold case of missing mum

Police are offering a $500,000 reward for information to help solve a cold case that suspect was a murder. Tammy Lisa Dyson, also known as Tamela Menzies, was 23 when went missing from the Currumbin area in 1995. The mother of two was picked up from a drug rehab clinic by a woman claiming to be her sister on July 20, 1995 and has not been seen since. Dyson was born and raised in Victoria before moving to Brisbane in 1988, where she worked in the adult entertainment industry under the nickname "Pebbles". Police believe she began mixing with criminals and using drugs while working in strip clubs on the Gold Coast. In early 1995 Dyson arranged for her young sons, Jyles and Rainey, to stay with their grandmother in Victoria temporarily. A few months later she made a distressed call to her sister Olivia, who said she had been assaulted. Olivia and her partner then dropped Dyson off to a drug rehabilitation centre at Currumbin on the Gold Coast, and on July 20, 1995 she was picked up by someone claiming to be her sister. The following day, Tammy completed a statutory declaration signed by a Justice of the Peace in Tweed Heads, giving custody of her children and her possessions to her mother. She also called her sister one last time, with Olivia recalling that Tammy "didn't sound like herself" and she had mentioned underworld figures. Police have received a number of reported sightings of Tammy since 1995 but all proof of life inquiries have been proven negative. In 2012, the Queensland coroner said that they believed Tammy was deceased and indicated that she may have been a victim of violence, although a certain date, time and cause of death have not been determined. Police are now offering the huge reward for new information and immunity from prosecution for any accomplice who comes forward. "Tammy associated with criminals that were known to police and vanished without a trace after giving custody of her children and possessions to her mother; we believe the circumstances of her disappearance is suspicious," Detective Senior Sergeant Tara Kentwell said. On Wednesday, her sons, who were only three and one when their mother disappeared, made an emotional appeal for public help to find her. "Growing up without mum and not knowing what happened to her has been very hard," Jyles Lebler said through tears during a media conference. "Whoever has picked her up, I'm not saying they have done something but they must know something bad has happened." "We hope we find out what to mum to give grandma some closure before it's too late," Rainey added. Images: Queensland Police

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

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> When you think of eye infections, what comes to mind?

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>. <figure><iframe src="https://www.youtube.com/embed/pWsx8i1kaxs?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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. 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. 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. <h2>Conjunctivitis</h2> 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>. <figure><iframe src="https://www.youtube.com/embed/RZ4danuJwd0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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. <h2>Blepharitis</h2> 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">Staphylococcus 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. <h2>Stye</h2> 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 S aureus form of the Staphylococcus species</a>. <figure><iframe src="https://www.youtube.com/embed/INKrGOdy824?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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. <h2>Keratitis</h2> 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. 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>. 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. <h2>Uveitis</h2> <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>. <h2>Exogenous endophthalmitis</h2> 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>. <h2>Dacryocystitis</h2> 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">Streptococcus pneumoniae and Staphylococcus aureus</a> bacteria. 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. <h2>Careful with contacts</h2> Proper eye hygiene reduces the risk of all these conditions – and this is even more important for contact lens wearers. <figure><iframe src="https://www.youtube.com/embed/uENHAntJOIA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> 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>. Any persistent and painful redness or swelling of eyes should be checked by a registered health professional.<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/227252/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
