World's oldest woman turns 117

<p>One of the world's oldest living person has turned 117. </p> <p>Maria Branyas Morera born on March 4, 1907 in San Francisco, lived through the 1918 pandemic, the two World Wars, Spain’s civil war and fully recovered after contracting Covid just days before her 113th birthday. </p> <p>She was one of the world's oldest Covid survivor's in 2020 and is now the 12th oldest verified person in history. </p> <p>Maria, who moved to Catalonia, Spain when she was eight, proudly announced her age on X, formerly known as Twitter in a post that read:  “Good morning, world. Today I turn 117 years old. I’ve come this far.”</p> <p>Maria, who has lived in a nursing home for the past 23 years, is healthier than ever aside from hearing difficulties and mobility issues, and scientists are studying her to find out the secrets to a long life. </p> <p>“She remembers with impressive clarity events from when she was only four years old, and she does not present any cardiovascular disease, common in elderly people," Scientist Manel Esteller told Spanish outlet <em>ABC</em>.</p> <p>“It is clear that there is a genetic component because there are several members of her family who are over 90 years old.”</p> <p>Scientists and Maria are working together to gain further insights into living longer, and researchers hope that studying Maria’s genes will help with the development of drugs which could combat diseases associated with ageing.</p> <p>Maria had three children with her husband  a Catalan doctor named Joan Moret.</p> <p>Her husband passed away 1976, and Maria also outlived her only son, August who tragically passed away in a tractor accident when he was 86. </p> <p>Maria now has two daughters, 11 grandchildren and 11 great-grandchildren.</p> <p>The oldest person ever established was a Frenchwoman named Jeanne Calment, who lived to the age of 122 years and 164 days.</p> <p><em>Image: news.com.au/ Guiness Book of Records</em></p>

Altitude sickness is typically mild but can sometimes turn very serious − a high-altitude medicine physician explains how to safely prepare

<p><em><a href="https://theconversation.com/profiles/brian-strickland-1506270">Brian Strickland</a>, <a href="https://theconversation.com/institutions/university-of-colorado-anschutz-medical-campus-4838">University of Colorado Anschutz Medical Campus</a></em></p> <p>Equipped with the latest gear and a thirst for adventure, mountaineers embrace the perils that come with conquering the world’s highest peaks. Yet, even those who tread more cautiously at high altitude are not immune from the health hazards waiting in the thin air above.</p> <p>Altitude sickness, which most commonly refers to <a href="https://medlineplus.gov/ency/article/000133.htm">acute mountain sickness</a>, <a href="https://doi.org/10.1016/j.pcad.2010.02.003">presents a significant challenge</a> to those traveling to and adventuring in high-altitude destinations. Its symptoms can range from <a href="https://doi.org/10.1089/ham.2017.0164">mildly annoying to incapacitating</a> and, in some cases, may progress to more <a href="https://doi.org/10.1183/16000617.0096-2016">life-threatening illnesses</a>.</p> <p>While <a href="https://doi.org/10.18111/9789284424023">interest in high-altitude tourism is rapidly growing</a>, general awareness and understanding about the hazards of visiting these locations <a href="https://doi.org/10.1089/ham.2022.0083">remains low</a>. The more travelers know, the better they can prepare for and enjoy their journey.</p> <p>As an <a href="https://som.cuanschutz.edu/Profiles/Faculty/Profile/36740">emergency physician specializing in high-altitude illnesses</a>, I work to improve health care in remote and mountainous locations around the world. I’m invested in finding ways to allow people from all backgrounds to experience the magic of the mountains in an enjoyable and meaningful way.</p> <h2>The science behind altitude sickness</h2> <p>Altitude sickness is rare in locations lower than 8,200 feet (2,500 meters); however, <a href="https://www.ncbi.nlm.nih.gov/books/NBK430716/">it becomes very common</a> when ascending above this elevation. In fact, it affects about <a href="https://wwwnc.cdc.gov/travel/yellowbook/2024/environmental-hazards-risks/high-elevation-travel-and-altitude-illness">25% of visitors to the mountains of Colorado</a>, where I conduct most of my research.</p> <p>The risk rapidly increases with higher ascents. Above 9,800 feet (3,000 meters), up to <a href="https://www.ncbi.nlm.nih.gov/books/NBK430716/">75% of travelers</a> may develop symptoms. Symptoms of altitude sickness are usually mild and consist of <a href="https://doi.org/10.1089/ham.2017.0164">headache, dizziness, nausea, fatigue and insomnia</a>. They usually <a href="https://doi.org/10.1016/j.rceng.2019.12.009">resolve after one to two days</a>, as long as travelers stop their ascent, and the symptoms quickly resolve with descent.</p> <p>When travelers do not properly acclimatize, they can be susceptible to life-threatening altitude illnesses, such as <a href="https://doi.org/10.1016/j.resp.2007.05.002">high-altitude pulmonary edema</a> or <a href="https://doi.org/10.1089/1527029041352054">high-altitude cerebral edema</a>. These conditions are characterized by fluid accumulation within the tissues of the lungs and brain, respectively, and are the <a href="https://wwwnc.cdc.gov/travel/yellowbook/2024/environmental-hazards-risks/high-elevation-travel-and-altitude-illness">most severe forms of altitude sickness</a>.</p> <p>Altitude sickness symptoms are thought to be caused by <a href="https://doi.org/10.1093%2Fbjaceaccp%2Fmks047">increased pressure surrounding the brain</a>, which results from the failure of the body to acclimatize to higher elevations.</p> <p>As people enter into an environment with lower air pressure and, therefore, <a href="https://doi.org/10.1001/jamanetworkopen.2023.18036">lower oxygen content</a>, their <a href="https://doi.org/10.1093%2Fbjaceaccp%2Fmks047">breathing rate increases</a> in order to compensate. This causes an increase in the amount of <a href="https://doi.org/10.1016/s1357-2725(03)00050-5">oxygen in the blood as well as decreased CO₂ levels</a>, which then increases blood pH. As a result, the <a href="https://doi.org/10.1093%2Fbjaceaccp%2Fmks047">kidneys compensate</a> by removing a chemical called bicarbonate from the blood into the urine. This process makes people urinate more and helps correct the acid and alkaline content of the blood to a more normal level.</p> <figure><iframe src="https://www.youtube.com/embed/iv1vQPIdX_k?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Tips for preventing or reducing the risk of altitude sickness.</span></figcaption></figure> <h2>The importance of gradual ascent</h2> <p>High-altitude medicine experts and other physicians <a href="https://doi.org/10.1016/s0140-6736(76)91677-9">have known for decades</a> that <a href="https://doi.org/10.1089/ham.2010.1006">taking time to slowly ascend is the best way</a> to prevent the development of altitude sickness.</p> <p>This strategy gives the body time to complete its natural physiologic responses to the changes in air pressure and oxygen content. In fact, spending just <a href="https://doi.org/10.1089/ham.2010.1006">one night at a moderate elevation</a>, such as Denver, Colorado, which is at 5,280 feet (1,600 meters), has been shown to <a href="https://doi.org/10.7326/0003-4819-118-8-199304150-00003">significantly reduce the likelihood of developing symptoms</a>.</p> <p>People who skip this step and travel directly to high elevations are <a href="https://doi.org/10.1093/jtm/taad011">up to four times more likely</a> to develop altitude sickness symptoms. When going to elevations greater than 11,000 feet, multiple days of acclimatization are necessary. Experts generally recommend ascending <a href="https://doi.org/10.1089/ham.2010.1006">no more than 1,500 feet per day</a> once the threshold of 8,200 feet of elevation has been crossed.</p> <p>Workers at high altitude, such as <a href="https://doi.org/10.1089/ham.2020.0004">porters in the Nepali Himalaya</a>, are at <a href="https://doi.org/10.1016/j.wem.2018.06.002">particular risk of altitude-related illness</a>. These workers often do not adhere to acclimatization recommendations in order to maximize earnings during tourist seasons; as a result, they are more likely to experience <a href="https://www.cdc.gov/travel/yellowbook/2024/environmental-hazards-risks/high-elevation-travel-and-altitude-illness">severe forms of altitude sickness</a>.</p> <h2>Effective medications</h2> <p>For more than 40 years, <a href="https://doi.org/10.1056/nejm196810172791601">a medicine called acetazolamide</a> has been used to <a href="https://medlineplus.gov/druginfo/meds/a682756.html">prevent the development of altitude sickness</a> and to treat its symptoms. Acetazolamide is <a href="https://www.ncbi.nlm.nih.gov/books/NBK557838/">commonly used as a diuretic</a> and for the <a href="https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/glaucoma">treatment of glaucoma</a>, a condition that causes increased pressure within the eye.</p> <p>If started <a href="https://doi.org/10.1378/chest.09-2445">two days prior</a> to going up to a high elevation, acetazolamide can <a href="https://doi.org/10.1378/chest.09-2445">prevent symptoms of acute illness</a> by speeding up the acclimatization process. Nonetheless, it does not negate the recommendations to ascend slowly, and it is <a href="https://doi.org/10.1016/j.wem.2019.04.006">routinely recommended only</a> when people cannot slowly ascend or for people who have a history of severe altitude sickness symptoms even with slow ascent.</p> <p>Other medications, including ibuprofen, have <a href="https://doi.org/10.1016/j.wem.2012.08.001">shown some effectiveness</a> in treating acute mountain sickness, although <a href="https://doi.org/10.1016/j.amjmed.2018.10.021">not as well as acetazolamide</a>.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/2028586/">steroid medication called dexamethasone</a> is effective in both treating and preventing symptoms, but it does not improve acclimatization. It is <a href="https://doi.org/10.1016/j.wem.2019.04.006">recommended only when acetazolamide is not effective</a> or cannot be taken.</p> <p>Additionally, it is important to <a href="https://wwwnc.cdc.gov/travel/page/travel-to-high-altitudes">avoid alcohol during the first few days at higher altitudes</a>, as it impairs the body’s ability to acclimatize.</p> <h2>Unproven therapies and remedies are common</h2> <p>As high-altitude tourism becomes increasingly popular, multiple commercial products and remedies have emerged. Most of them are not effective or provide no evidence to suggest they work as advertised. Other options have mixed evidence, making them difficult to recommend.</p> <p>Medications such as <a href="https://doi.org/10.1089/ham.2007.1037">aspirin</a>, <a href="https://doi.org/10.1183/13993003.01355-2017">inhaled steroids</a> and <a href="https://doi.org/10.1089/ham.2011.0007">sildenafil</a> have been proposed as possible preventive agents for altitude sickness, but on the whole they have not been found to be effective.</p> <p><a href="https://doi.org/10.1093/qjmed/hcp026">Supplements and antioxidants have no proven benefit</a> in preventing or treating altitude sickness symptoms. Both normal and high-altitude exercise are popular ways to prepare for high elevations, especially among athletes. However, beyond <a href="https://doi.org/10.1097/jes.0b013e31825eaa33">certain pre-acclimatization strategies</a>, such as brief sojourns to high altitude, <a href="https://doi.org/10.1016/j.tmaid.2013.12.002">physical fitness and training is of little benefit</a>.</p> <p><a href="https://missouripoisoncenter.org/canned-oxygen-is-it-good-for-you">Canned oxygen</a> has also exploded in popularity with travelers. While <a href="https://doi.org/10.1016/0140-6736(90)93240-p">continuously administered medical oxygen</a> in a health care setting can alleviate altitude sickness symptoms, portable oxygen cans <a href="https://doi.org/10.1016/j.wem.2019.04.006">contain very little oxygen gas</a>, casting doubt on their effectiveness.</p> <p>Some high-altitude adventure travelers sleep in <a href="https://doi.org/10.2165/00007256-200131040-00002">specialized tents</a> that simulate increased elevation by lowering the quantity of available oxygen in ambient air. The lower oxygen levels within the tent are thought to accelerate the acclimatization process, but the tents aren’t able to decrease barometric pressure. This is an important part of the high-altitude environment that induces acclimatization. Without modifying ambient air pressure, these <a href="https://doi.org/10.1016/j.wem.2014.04.004">tents may take multiple weeks</a> to be effective.</p> <p>Natural medicines, such as <a href="https://doi.org/10.1580/08-weme-br-247.1">gingko</a> and <a href="https://doi.org/10.1186/s40794-019-0095-7">coca leaves</a>, are touted as natural altitude sickness treatments, but few studies have been done on them. The modest benefits and significant side effects of these options makes their use <a href="https://doi.org/10.1016/j.wem.2019.04.006">difficult to recommend</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/8469948/">Staying hydrated</a> is very important at high altitudes due to fluid losses from increased urination, dry air and increased physical exertion. <a href="https://doi.org/10.1186%2Fs12889-018-6252-5">Dehydration symptoms</a> can also mimic those of altitude sickness. But there is <a href="https://doi.org/10.1580/1080-6032(2006)17%5B215:AMSIOF%5D2.0.CO;2">little evidence that consuming excessive amounts of water</a> can prevent or treat altitude sickness.</p> <p>The mountains have something for visitors of all interests and expertise and can offer truly life-changing experiences. While there are health risks associated with travel at higher elevations, these can be lessened by making basic preparations and taking time to slowly ascend.<!-- Below is The Conversation's page counter tag.

“It turned to tragedy”: Three people dead after mass drowning

<p dir="ltr">Three people have died and another is in critical condition after drowning at the popular Phillip Island beach in Victoria. </p> <p dir="ltr">Emergency response teams were quick on the scene on Wednesday afternoon after four people were unresponsive after being pulled from the water at the beach notorious for dangerous rips. </p> <p dir="ltr">The victims are a man in his 40s and two women in their 20s, while another woman in her 20s is fighting for her life after being airlifted to hospital. </p> <p dir="ltr">An eyewitness told <em>7News</em> it was a “horrible” situation that unfolded. </p> <p dir="ltr">“The family was really upset,” the witness, Alex Tzatzimakis, said. “There seemed to be a group of 10 people who came here for a really nice day. Obviously it turned to tragedy.”</p> <p dir="ltr">She said that family members of the victims were crying and consoling each other, while beachgoers who pulled the bodies from the water attempted to perform CPR. </p> <p dir="ltr">One man could be heard wailing, <a href="https://www.heraldsun.com.au/leader/bass-coast/emergency-services-converge-on-forrest-caves-beach-phillip-island/news-story/1c8708162bf57f6f97c23e4306aedb2a">according to the <em>Herald Sun</em></a>, “I told them not to go – I should have been there.”</p> <p dir="ltr">The incident is understood to have occurred at Forrest Caves, a popular tourist destination on Phillip Island known for its sea caves, but is also an unpatrolled beach known for its dangerous rips. </p> <p dir="ltr">Locals have reacted to the horrific drowning, with many admitting they would not ever attempt to swim in the hazardous waters. </p> <p dir="ltr">“It’s treacherous out there,” one person wrote on Facebook. “Definitely not a swimming beach. Only if you are a strong swimmer and understand rips.”</p> <p dir="ltr">“So, so sad,” a second wrote. “Great surfing beach but not a swimming beach.”</p> <p dir="ltr">A third said, “If the island is going to be pushed so hard as a tourist destination there will be more and more incidents.”</p> <p dir="ltr">Drownings around Australia have risen this summer, with many people flocking to less busy unpatrolled beaches to escape the summer heat. </p> <p dir="ltr">In the days before the fatal Phillip Island drowning, Surf Life Saving Australia CEO Adam Weir told <em><a href="https://www.skynews.com.au/australia-news/tragic-summer-high-number-of-drowning-deaths-on-australian-beaches/video/a66cc0032dfe6482f9d7e023179de36c">Sky News Australia</a></em> the issue is “very concerning”.</p> <p dir="ltr">“We’ve had 33 drowning deaths around the country so far,” Mr Weir said.</p> <p dir="ltr">“And we’ve still got a month to go in summer, so it has been a tragic summer.”</p> <p dir="ltr" style="line-height: 1.38; margin-top: 0pt; margin-bottom: 18pt;"><em>Image credits: 9News</em><span id="docs-internal-guid-3041d316-7fff-6761-69a3-b703dcdbba4d"></span></p>

Sister of slain doctor calls for killers to turn themselves in

<p dir="ltr">The distraught sister of Dr Ash Gordon has made an emotional appeal for those responsible for the death of her brother to turn themselves in. </p> <p dir="ltr">In the early hours of Saturday morning, the 33-year-old doctor was killed after a group of criminals broke into his home in Doncaster in Melbourne’s east. </p> <p dir="ltr">After they stole several items from his home, he managed to chase them out of the house and pursued them in his car, until both he and the intruders exited their vehicles and a fight erupted just 500 metres away. </p> <p dir="ltr">Dr Gordon was stabbed fatally several times in the altercation and was left for dead. </p> <p dir="ltr">As his family grieve his premature death, his devastated sister Natalie has called for justice. </p> <p dir="ltr">Appearing on <em>Sunrise</em>, she shared how angry the situation has made her. </p> <p dir="ltr">“I think for me it's been anger the entire time. I'm just obviously devastated, but so angry that anyone could do this to not only my brother but any person, any human being,” she said.</p> <p dir="ltr">"His girlfriend is heartbroken, mum is completely broken and I've never seen my dad like this. You never want to have to bury your own children."</p> <p dir="ltr">Ms Gordon said her little brother had “a big personality with a large heart”, sharing how “his presence was known everywhere.”</p> <p dir="ltr">“He had a cheeky grin, a charm and charisma about him that had everyone wrapped around his little finger.”</p> <p dir="ltr">“He was the absolute apple of all of our eyes. He was the centre of our family and he was the youngest of five but we all looked up to him.”</p> <p dir="ltr">While Dr Gordon's attackers remain on the run and no arrests have been made, Natalie has pleaded for the killers to turn themselves in to police. </p> <p dir="ltr">“Wear the consequences, because you'll never imagine what we're feeling, what we're going through,” she said.  </p> <p dir="ltr">“You have taken away a wonderful doctor, a caring man and the best little brother.

Couple misses their own wedding after cruise ship forced to turn back

<p>A couple has missed their own dream destination wedding after their cruise ship was denied entry into New Zealand. </p> <p>Janine Sherriff and Kyle Risk dreamed of exchanging rings at the popular Lord of the Rings filming location, Hobbiton, located on the north island of New Zealand. </p> <p>The couple were meant to meet up with some close friends and family in New Zealand, as they travelled across from Australia on a P&amp;O cruise ship, but were turned back from docking over an unclean hull. </p> <p>The “Kiwi Adventure” cruise, which was meant to be a 13-day journey, turned into more of a Tasmanian adventure after the ship was told to head to Australia’s southernmost state instead.</p> <p>New Zealand’s biosecurity laws were triggered over just three juvenile mussels and one single hydroid (AKA: lace coral), which needed to be removed from the ship's hull. </p> <p>“We took the time off from work, we had our nearest and dearest friends and family all co-ordinate to be in New Zealand at this exact time,” Janine told the <em><a href="https://www.abc.net.au/news/2023-11-25/cruise-ship-turned-away-from-nz/103151078">ABC</a></em>.</p> <p>“The plan was to get off the boat, go straight to Hobbiton, have our wedding, then head straight back to the boat for the rest of the honeymoon.”</p> <p>“Now we have to figure out what to do about our wedding, we have all this money down the drain. I am heartbroken this day has been taken away from me."</p> <p>Kyle added, “First off, I was furious.” </p> <p>“I saw Janine’s face when we got the news. I was ready to explode.</p> <p>“I got a selfie from our family and friends at the site in Hobbiton we should have been on about 20 minutes before we had to turn around.”</p> <p>“It would have meant a lot as it was a beautiful setting. As long as we have each other,” he added.</p> <p>The cruise operator in charge of the vessel, P&amp;O, has offered customers $300 in on-board credit and a 50 per cent credit on a future cruise.</p> <p>“We apologise for the change in itinerary and thank our guests for their patience and understanding,” a spokesperson for the company’s Australian division said per the <em><a href="https://www.dailymail.co.uk/news/article-12791331/Engaged-couple-P-O-cruise-forced-turn-New-Zealand-fume-dream-Lord-Rings-wedding-ruined.html">Daily Mail</a></em>.</p> <p><em>Image credits: Facebook / Shutterstock</em></p>

These affect our <a href="https://pubmed.ncbi.nlm.nih.gov/36165756/">mental health</a> in a multitude of <a href="https://www.nature.com/articles/s41558-018-0102-4">ways</a>.</p> <p>Coping with climate change can be overwhelming. Sometimes, the best someone can do is to seek refuge in alcohol, tobacco, over-the-counter and prescription drugs, or other psychoactive substances. This is understandable, but dangerous, and can have serious consequences.</p> <p>We outline <a href="https://journals.sagepub.com/doi/full/10.1177/17456916221132739">five ways</a> climate change could increase the risk of harmful substance use.</p> <h2>1. Mental health is harmed</h2> <p>Perhaps the most obvious way climate change can be linked to harmful substance use is by damaging mental health. This <a href="https://onlinelibrary.wiley.com/doi/10.1111/dar.12448">increases the risk</a> of new or worsened substance use.</p> <p>People with a mental disorder are <a href="https://www.hindawi.com/journals/psychiatry/2018/5697103/">at high risk</a> of also having a <a href="https://bmcpsychiatry.biomedcentral.com/articles/10.1186/1471-244X-11-25#:%7E:text=Prevalence%20of%20comorbidity%20in%20epidemiological%20studies&amp;text=Among%20subjects%20with%20an%20alcohol,a%20comorbid%20SUD%20%5B39%5D.">substance-use disorder</a>. This often precedes their mental health problems. Climate change-related increases in the number and nature of extreme events, in turn, are escalating risks to mental health.</p> <p>For example, extreme heat is linked to increased <a href="https://pubmed.ncbi.nlm.nih.gov/27727320/">distress</a> across the whole population. In extreme heat, more people go to the <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2789481">emergency department</a> for psychiatric problems, including for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0048969720338249">alcohol</a> and <a href="https://www.nature.com/articles/s43856-023-00346-1">substance use</a> generally. This is even true for <a href="https://www.sciencedirect.com/science/article/pii/S0048969720325572">a single very hot day</a>.</p> <p>Post-traumatic stress disorder, depression, anxiety and <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja13.10307">other mental health</a> problems are <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00367/full">common</a> at the time of extreme weather events and can persist for months, even years afterwards, especially if people are exposed to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9116266/">multiple events</a>. This can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6101235/">increase</a> the likelihood of using substances as a way to cope.</p> <h2>2. Worry increases</h2> <p>With <a href="https://climatecommunication.yale.edu/publications/climate-change-in-the-american-mind-beliefs-attitudes-december-2022/">increasing public awareness</a> of how climate change is endangering wellbeing, people are <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/articles/worriesaboutclimatechangegreatbritain/septembertooctober2022#:%7E:text=The%20level%20of%20worry%20about,lives%20right%20now%20(29%25).">increasingly worried</a> about what will happen if it remains unchecked.</p> <p>Worrying isn’t the same as meeting the criteria for a mental disorder. But <a href="https://www.undp.org/publications/peoples-climate-vote">surveys</a> show climate change generates complex emotional responses, <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(21)00278-3/fulltext">especially in children</a>. As well as feelings of worry, there is anxiety, fear, guilt, anger, grief and helplessness.</p> <p>Some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904966/">emotional states</a>, such as <a href="https://www.pnas.org/doi/full/10.1073/pnas.1909888116">sadness</a>, are linked with long-term tobacco use and also make substance use <a href="https://pubmed.ncbi.nlm.nih.gov/16011392/">relapse</a> more likely.</p> <h2>3. Physical injuries hurt us in many ways</h2> <p>Physical injuries caused by extreme weather events – such as smoke inhalation, burns and flood-related cuts and infections – increase the risk of harmful substance use. That’s partly because they <a href="https://pubmed.ncbi.nlm.nih.gov/20033251/">increase</a> the risk of psychological distress. If injuries cause long-term illness or disability, consequent feelings of hopelessness and depression can dispose some people to self-medicate with alcohol or other drugs.</p> <p>Substance use itself can also generate long-term physiological harm, disabilities or other chronic health problems. These are <a href="https://www.tandfonline.com/doi/abs/10.3109/00952999609001655">linked with</a> higher rates of harmful substance use.</p> <h2>4. Our day-to-day lives change</h2> <p>A single catastrophic event, such as a storm or flood, can devastate lives overnight and change the way we live. So, too, can the more subtle changes in climate and day-to-day weather. Both can disrupt behaviour and routines in ways that risk new or worsened substance use, for example, using stimulants to cope with fatigue.</p> <p>Take, for example, hotter temperatures, which disrupt <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(22)00209-3?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS2590332222002093%3Fshowall%3Dtrue">sleep</a>, undermine <a href="https://jhr.uwpress.org/content/57/2/400">academic performance</a>, <a href="https://www.nature.com/articles/s41562-017-0097">reduce physical activity</a>, and promote <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00173-5/fulltext">hostile language</a> and <a href="https://www.cambridge.org/core/elements/abs/climate-change-and-human-behavior/F64471FA47B8A6F5524E7DDDDE571D57">violent behaviour</a>.</p> <h2>5. It destabilises communities</h2> <p>Finally, climate change is destabilising the socioeconomic, natural, built and geopolitical <a href="https://www.nature.com/articles/s41558-018-0102-4">systems</a> on which human wellbeing – <a href="https://theconversation.com/climate-change-and-health-ipcc-reports-emerging-risks-emerging-consensus-24213">indeed survival</a> – depends.</p> <p>Damaged infrastructure, agricultural losses, school closures, homelessness and displacement are significant <a href="https://www.nature.com/articles/s41558-018-0102-4">sources of psychosocial distress</a> that prompt acute (short-term) and chronic (long-term) stress responses.</p> <p><a href="https://doi.org/10.1196/annals.1441.030">Stress</a>, in turn, can <a href="https://doi.org/10.1007/s002130100917">increase</a> the risk of <a href="https://link.springer.com/article/10.1007/s002130100917">harmful substance use</a> and make people more likely to relapse.</p> <h2>Why are we so concerned?</h2> <p>Substance-use disorders are economically and socially <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(18)30337-7/fulltext">very costly</a>. Risky substance use that doesn’t meet the criteria for a formal diagnosis <a href="https://digitalcommons.fiu.edu/srhreports/health/health/32/">can also harm</a>.</p> <p>Aside from its direct physical harm, harmful substance use disrupts <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3843305/">education</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3234116/">employment</a>. It increases the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6676144/">accidents</a> and <a href="https://www.tandfonline.com/doi/abs/10.1080/09595230600944479">crime</a>, and it undermines social relationships, intimate <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4795906/#:%7E:text=Results%20indicated%20that%20alcohol%20use,drinkers%20with%20low%20relationship%20satisfaction.">partnerships</a> and <a href="https://www.cambridge.org/core/journals/development-and-psychopathology/article/abs/longitudinal-relations-between-parental-drinking-problems-family-functioning-and-child-adjustment/CE508589A9E799FD6DC9E23DF364FB8F">family functioning</a>.</p> <h2>Politicians take note</h2> <p>As we head towards the <a href="https://www.cop28.com">COP28 global climate talks</a> in Dubai, climate change is set to hit the headlines once more. Politicians know climate change is undermining human health and wellbeing. It’s well past time to insist they act.</p> <p>As we have seen for populations as a whole, there are multiple possible ways for climate change to cause a rise in harmful substance use. This means multidimensional <a href="https://www.nature.com/articles/s41558-018-0102-4">prevention strategies</a> are needed. As well as addressing climate change more broadly, we need strategies including:</p> <ul> <li> <p>supporting vulnerable individuals, especially <a href="https://journals.sagepub.com/doi/full/10.1177/21677026211040787">young people</a>, and marginalised commmunities, who are <a href="https://www.nature.com/articles/s41558-018-0102-4">hit hardest</a> by extreme weather-related events</p> </li> <li> <p>focusing health-related policies more on broadscale health promotion, for example, healthier eating, active transport and community-led mental health support</p> </li> <li> <p>investing in climate-resilient infrastructure, such as heat-proofing buildings and greening cities, to prevent more of the destabilising effects and stress we know contributes to mental health problems and harmful substance use.</p> </li> </ul> <p>There is now <a href="https://news.un.org/en/story/2022/10/1129912">no credible pathway</a> to avoiding dangerous climate change. However, if <a href="https://carnegieendowment.org/2023/01/12/climate-protests-tracking-growing-unrest-pub-88778#:%7E:text=These%20are%20just%20a%20few,even%20more%20numerous%20and%20influential.">increasing rates</a> of climate protests are anything to go by, the world may finally be ready for radical change – and perhaps for reduced harmful substance use.<!-- Below is The Conversation's page counter tag.

Cruise ship forced to turn back after 100 passengers injured in storm

<p>The Spirit of Discovery cruise ship was forced to turn back after around 100 passengers were injured during a massive storm. </p> <p>Cruise company Saga have said that most of the injuries were minor, but five people had to be taken to hospital when the ship returned to England on Tuesday local time. </p> <p>One passenger told<em> BBC News</em> that a few passengers  "feared for their lives", when the storm hit the ship in the Bay of Biscay, off the French coast. </p> <p>"People were writing texts to their loved ones in case we capsized," they added. </p> <p>"The tone of voice in our captain... he was physically scared. We had crew crying. We had many passengers in awful states of fear." </p> <p>The passenger also claimed that that injuries included broken bones and cuts, with reports of furniture flying around and  people  being knocked off their feet, as the ship stopped moving and veered dramatically to one side as part of its safety manoeuvre. </p> <p>Another passenger, 75-year-old Jan Bendall, told the BBC that she and her husband were "holding on for dear life", and that it was overall a frightening experience. </p> <p>"It was quite frightening, I'm not somebody who frightens easily," Bendall said.</p> <p>"We were lucky - we're quite able-bodied, but I think some of the older people and people in their own cabins were quite worried," she added.</p> <p>The ship itself holds almost 1000 passengers and holds cruises for people over 50. </p> <p>Saga told the <em>BBC </em>that there had been "very limited" damage and the ship had "remained safe at all times." </p> <p>"While the weather is clearly beyond our control, we want to offer our sincere apologies to all those affected who are now safely on their way home in calmer seas," the spokesperson said.</p> <p><em>Images: Nine News/ Facebook</em></p> <p> </p>

"These guys have held on": Why a family turned down $50 million for their home

<p>A Sydney family has repeatedly refused to sell their family home to major developers, despite being offered an eight-figure sum for the property. </p> <p>The Zammit family have lived in their impressive home for several decades and have said time and time again that they have no intentions of selling the house, which is situated on a 20,000 square metre parcel of land in western Sydney. </p> <p>With the massive area of land being smack bang in the centre of a major housing development, some realtors have estimated that the property could fetch a price as high as $50 million.</p> <p>Despite the family saying they would be staying in the home, documents obtained by <a href="https://www.news.com.au/finance/real-estate/selling/sydney-familys-home-goes-from-858k-to-50m-as-major-development-crops-up/news-story/eb0bacc20cdae5cad461ff89797cb71d" target="_blank" rel="noopener"><em>news.com.au</em></a> have confirmed that the house was up for sale in both 2015 and and 2016. </p> <p>The house was swiftly taken off the market after being initially listed with a price range $858,000 to $945,000.</p> <p>And just a few years later, they are believed to have received offers of between $33 million and $50 million.</p> <p>The massive property boasts a lush green lawn in stark contrast to all the houses around it and also a huge 200 metre driveway.</p> <p>But just metres away are rows and rows of carbon copy grey houses crammed into tight blocks as part of a major development. </p> <p>The high-density neighbouring homes are built right up to the fence of the Zammit's property, and neighbours reportedly don’t want the owners to sell as they like living in a cul-de-sac.</p> <p>It’s estimated that 50 houses could fit on the Zammit's block of land if they followed the same style as other developer homes in the area. </p> <p>A local real estate agent previously praised the Zammit family for staying put, despite the big payouts they have likely been offered.</p> <p>“The fact that most people sold out years and years ago, these guys have held on. All credit to them,” Ray White Quakers Hill agent Taylor Bredin told <em>7News.</em></p> <p>“Depending on how far you push the development plan, you’d be able to push anywhere from 40 to 50 properties on something like this, and when subdivided, a 300 square metre block would get a million dollars.”</p> <p><em>Image credits: 7News</em></p>

"Hot girl summer": Jackie O turns heads in swimsuit on enchanting getaway

<p>Radio host Jackie 'O' Henderson has embarked on a "magical" vacation to Ningaloo Reef in Western Australia, accompanied by her close friend, Gemma O’Neill – leaving left her fans in awe with the beachside photos she shared online.</p> <p>The 48-year-old shared an image of herself and Gemma on the sandy shore, prompting her followers to declare that Jackie was fully embracing a "hot girl summer".</p> <p>"Deserted beaches, sunsets, super moons, no phones, and swimming with gentle whale sharks 💛 @gemmyjean, thank you for this incredible birthday gift," Jackie captioned the photos, some of which showed the duo swimming alongside these magnificent creatures.</p> <p>"Wow, that looks absolutely amazing 🙌," remarked Kylie Gillies.</p> <p>"It looks absolutely incredible! Adding it to my list ❤️❤️❤️," chimed in Michelle Bridges.</p> <p>"Your beautiful friendship with Gem is heartwarming. Hip, hip hooray, Jack! ❤️," gushed Melissa Hoyer.</p> <p>"Seems like you had a blast on your little getaway! Looks like so much fun," one user commented, while another exclaimed, "Absolutely stunning!"</p> <p>"That's the way to live 🙌," added a third.</p> <p>"Radiant beauties basking in the joy of life!" another fan noted.</p> <p>Several others complimented Jackie, calling her "gorgeous" and the experience "magical".</p> <p>This exciting adventure followed an amusing incident in which Jackie was caught with an embarrassing item in her luggage while en route to Western Australia.</p> <p>Before her departure, the producers of the Kyle and Jackie O show surreptitiously placed a large vibrator in her carry-on bag, ensuring it would be discovered by airport security by attaching it to a sizeable aerosol can.</p> <p>Jackie recounted the prank to her listeners on-air, stating, "That [phallic object] was in my suitcase, planted by our staff, so that when I went through security, it was uncovered. I could have died!"</p> <p>"They placed this [adult toy] in my bag, thinking it would be a funny joke," she continued. "[Airport security] showed me the X-ray and asked, 'What is this?'

Why does my hair turn green from the swimming pool?

<p><em><a href="https://theconversation.com/profiles/magdalena-wajrak-1432339">Magdalena Wajrak</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>If you are a blonde like me and enjoy laps in a swimming pool, you may have noticed your hair acquires a green tint after frequent swims in chlorinated water.</p> <p>This happens to both bleached and natural blondes. In fact, the green tinge happens to everyone, but it’s less visible on dark hair and those whose hair isn’t damaged by chemical treatments such as bleaching.</p> <p>But what exactly causes this green discoloration, and what can we do about it? Most of us blame the chlorine in the pool water. However, although chlorine does play a part, it is not the main culprit.</p> <h2>Which chemicals in the pool turn the hair green?</h2> <p>The element to blame for the green staining of hair is copper.</p> <p>The main source of copper is copper sulfate (CuSO₄), a compound added to swimming pools to prevent the growth of algae. <a href="https://www.sciencedirect.com/science/article/pii/S1568988320301803?via%3Dihub">Contact with algae</a> can cause skin irritation and respiratory issues, and ingesting water with algae can lead to serious gastrointestinal problems. Only a small amount (around 0.5mg per litre or 0.5 parts per million) of copper sulfate is needed to prevent algal growth.</p> <p>However, copper can also enter swimming pools through the corrosion of water pipes, so concentrations may be higher in some pools.</p> <p>Copper sulfate crystals are greenish-blue in colour. So, when hair comes into contact with copper ions – a positively charged variant of a copper atom with extra electrons – those ions get absorbed by the hair and cause the greenish hue.</p> <p>Scientists were fascinated by the green “pool hair” phenomenon as far back as the 1970s, so we actually have research data on copper being the cause.</p> <p>One very <a href="https://jamanetwork.com/journals/jamadermatology/article-abstract/538197">interesting study in 1978</a> performed experiments by immersing hair samples into water containing different concentrations of copper ions, chlorine and various pH values (neutral and basic). Their results showed hair exposed to free copper ions does turn green.</p> <p>Furthermore, when hair is oxidised (meaning electrons are removed from the hair proteins) by chlorine, it actually damages the hair, enhancing the absorption of copper ions. Hair submerged in water with chlorine but without copper ions did not turn green. Meanwhile, hair exposed to water with only copper ions and no chlorine still formed a green colour.</p> <p>Hence, chlorine by itself does not play a role in causing the green hue we see in “pool hair”, but it does exacerbate it.</p> <h2>So, how does copper get into the hair?</h2> <p><a href="https://doi.org/10.1007/978-1-4684-0943-7_24">Other research teams</a> have conducted <a href="https://doi.org/10.1071/ch9682437">more extensive studies</a>, using sophisticated instruments, such as scanning electron microscopy, to examine how exactly copper ions attach to the hair.</p> <p>Our hair is predominantly composed of protein called keratin. Keratin is classified as a “structural fibrous protein”, meaning it has an elongated, sheet-like structure.</p> <p>The keratin structure is composed of various <a href="https://chem.libretexts.org/Courses/University_of_Kentucky/UK%3A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)/Chapters/Chapter_4%3A_Structure_and_Function/4.4%3A_Functional_Groups">chemical groups</a> (types of atom groupings with similar properties), such as carboxyl groups, amino groups and disulfide groups. Copper ions have the ability to form bonds with these groups, forming a copper-keratin complex. This complex remains in the hair, causing it to appear green.</p> <p>Interestingly, the most recent study <a href="https://doi.org/10.32657/10356/142466">conducted in 2020</a>, showed copper ions mainly bind to the disulfide groups. This study also found other metal ions such as zinc, lead, chromium and mercury also bind to hair in the same way. This is very useful in <a href="https://theconversation.com/forensic-breakthrough-study-suggests-humans-can-be-identified-by-the-proteins-in-their-hair-65051">forensic analysis</a>, for example, because forensic scientists can analyse hair samples to determine if a person has been exposed to a particular metal.</p> <p>Light-coloured hair already has the most visible green discoloration, but research has shown that damaged hair, caused by bleaching, straightening, or exposure to sun, is the <a href="https://pubmed.ncbi.nlm.nih.gov/19586601/">most susceptible</a> to the binding of copper ions. This is because in damaged hair the disulfide groups have “broken bonds” (the link that holds the elements within these groups together is broken), making it easier for the copper ions to bind to the hair.</p> <h2>Can I prevent the green colour or get rid of it?</h2> <p>To prevent your hair from turning green in a swimming pool, you have two basic options. The first is a physical barrier – just wear a swim cap.</p> <p>The second option is chemical – you can pre-treat your hair with an alkaline shampoo. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0891584918310050">Studies have shown</a> under alkaline pH conditions, the copper ions won’t attach to the hair. To treat your hair before going to the pool, you can either use a shampoo with a pH higher than 7, or you can even try mixing some baking soda into your regular shampoo.</p> <p>But what can you do if your hair has already turned greenish? Well, you can try washing your hair with a shampoo designed to achieve this, typically marketed as a “chlorine removal” shampoo. These products contain a chemical called EDTA – it can bind to metal ions (such as copper) and thus will remove copper from the hair.</p> <p>You may have heard tomato sauce or ketchup is a good way to get the green out of your pool hair – potentially because the red pigments are supposed to “cancel out” the green ones. However, I’m not aware of any scientific evidence this would work.</p> <p><em>Correction: This article has been amended to clarify that alkaline shampoos have a pH higher than 7, not lower.</em><!-- Below is The Conversation's page counter tag.

7 tips to help turn your cat into a friendly member of the family

<p><strong>How to make your cat love you</strong></p> <p>Getting a cat to be more affectionate is the yearning of many a pet owner. Some cats are antisocial when it comes to being picked up, cuddled or petted (much less sitting in a person’s lap). Other kitties are born loving this sort of attention.</p> <p>If you’re not lucky enough to have a cat who automatically seeks out your affection, trying to entice that reclusive furball to become your snuggle buddy may take some motivation and determination on your part. Your pet may never convert to a drooly lap cat, even after weeks of effort on your part, but at the very least you’ll probably strengthen your relationship with your cat.</p> <p><strong>Get the basics down</strong></p> <p>The initial stage of coaxing a cat into being more lovable is to let her recognise your positive intentions by dependably offering her good food, clean water, fun toys to play with and a litterbox that is cleaned regularly. When she’s happier, you’ll be happier, and these mutual good feelings will carry over into your relationship together.</p> <p>Spend extra time with your cat, letting her see you not as her owner but as her friend, meal provider and guardian. If she’s not coming up to you to say hi, be proactive: Walk over to her (as long as she’s not super-shy) and lavish affection on her. Once she gets used to all this attention, she might very well start seeking it out from you.</p> <p><strong>Be affectionate while feeding </strong></p> <p>While preparing her food (or making a production of opening that can of food), talk to your kitty. When she begins eating, gently stroke her a few times. This will help her associate being petted with a positive experience.</p> <p><strong>Be playful </strong></p> <p>Instead of trying to force a hug from your reluctant cat, play with her a little, maybe getting her to paw at a piece of string or chase after a laser pointer.</p> <p><strong>Try a little catnip</strong></p> <p>Bringing out a tin of catnip often brings timid felines out of their shells, and aloof cats sometimes become far friendlier under the influence of catnip.</p> <p><strong>Use the "slow blink"</strong></p> <p>Remember that using the “slow blink” as a non-verbal statement saying “I love you” will go a much longer way with your cat, versus a direct stare, which she may take as a threat.</p> <p><strong>Don't chase</strong></p> <p>Don’t try to push affection on your cat – for example, running after her. This might work with a dog, but chasing usually causes a scaredy cat to jolt off in another direction feeling victimised. And I should hope it goes without saying, but don’t punish or yell at your shy cat.</p> <p><strong>Give them a treat</strong></p> <p>Each time you share a session of tenderness with your cat, give her a treat. Let her see that this affectionate behaviour has its rewards.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/pets/7-tips-to-make-your-cat-more-friendly" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

The hilarious reason Dolly Parton turned down tea with Princess Kate

<p>It's been a remarkable year for country legend Dolly Parton, that she even received an invitation to tea with Princess Kate Middleton. </p> <p>Unfortunately, the icon had to decline and shared the hilarious reason why on her latest interview with <em>BBC Radio 2</em>. </p> <p>“This time, Lordy, I even got invited to have tea with Kate but I couldn’t even go," the country queen revealed about her time in London. </p> <p>“I thought it was very sweet and nice of her to invite me and one of these days I’m going to get to do that – that would be great," she added. </p> <p>When asked why she couldn't attend the prestigious afternoon tea, Parton joked: “She wasn’t going to promote my rock album so I had to say no.”</p> <p>On a more serious note, she said that despite her love for the people and London, she "unfortunately" doesn't have enough time to explore the city while she's there on business. </p> <p>The icon has been booked and busy with an upcoming rock album that is set to be released on November. </p> <p>Earlier this month she released <em>Let It Be</em>, a cover of the iconic Beatles song which she sang with two members of the band Paul McCartney and Ringo Starr.</p> <p>She's also been very active in her charity work, particularly her Imagination Library, which she founded and is currently expanding to help more children get free books up until they turn five. </p> <p><em>Images: Getty</em></p> <p> </p>

“Turn your phone off”: The simple reason behind Albanese’s warning

<p>Prime Minister Anthony Albanese has issued a clear warning to the public, advising them to "turn their phones off" as a safety measure to avoid potential dangers.</p> <p>Albanese delivered this cautionary message last week while announcing the appointment of Australia's first national cybersecurity coordinator, Air Commander Darren Goldie of the Royal Australian Air Force.</p> <p>Goldie was quick to echo the Prime Minister's sentiments, emphasising the importance of mobilising both the private sector and consumers in the fight against cyber threats.</p> <p>"We all bear responsibility in this matter. Simple actions, such as turning off your phone every night for five minutes, can make a significant difference.</p> <p>"I encourage everyone watching to adopt this practice once every 24 hours, perhaps while engaging in daily routines like brushing your teeth," stated Albanese during the press conference.</p> <p>While rebooting your device on a daily basis may seem like a basic precaution, it can greatly enhance your protection against cybercriminals. Often, various applications and processes continue running in the background of your phone or computer, even when you're not actively using them.</p> <p>If unauthorised individuals gain access to these apps and processes, they can monitor your activities and collect your data, including financial information and identification documents, and even hijack your webcam or phone camera.</p> <p>By rebooting your phone, you force the closure of all background applications and processes, effectively evicting anyone attempting to track your virtual movements.</p> <p>Priyadarsi Nanda, a cybersecurity expert at the University of Technology Sydney, supported Albanese's advice, emphasising the importance of periodically turning off one's phone.</p> <p>"Considering how extensively we use smartphones in our daily lives, there have been cases where individuals haven't turned off their phones for an entire year," Dr. Nanda told <em>The Guardian</em>.</p> <p>"If there is a malicious process running, switching off the phone breaks the chain. While it may only provide protection while the phone is off, it undoubtedly frustrates potential hackers. Although not foolproof, rebooting can make it more challenging for hackers to compromise your device."</p> <p>It is crucial to note that this measure does not safeguard against all forms of cybercrime. If your password has been stolen or you are being repeatedly and strategically targeted, for example, a simple reboot is unlikely to deter the most persistent hackers.</p> <p><em>Image: Wikimedia / Australian Government</em></p>

Mysterious liquid turns popular rock pool green

<p>A mysterious liquid has turned a popular public rock pool at Cronulla beach fluorescent green.</p> <p>The liquid, believed to be a natural fluorescent dye, fluorescein, was seen pouring into the usually clear waters of the pool on Friday.</p> <p>The dye is often used to help experts track the flow of water to identify any leaks and has low toxicity, which means it is harmless despite the daunting colour.</p> <p>“We believe the discolouration is likely to be fluorescein dye, which is commonly used in plumbing/drain testing and dissipates quickly once diluted,” a spokesperson for the New South Wales Environmental Protection Authority said.</p> <p>According to Australian dye manufacturer, Tintex, the dye is also used to “locate leaks in plumbing, tracing pipe locations, detect drain damage and water pathways,” and is odourless and non-toxic to the environment.</p> <p>However, in a safety data sheet, Tintex has also warned about the potential health effects which include eye irritation, skin irritation, irritation of the digestive tract and respiratory tract irritation.</p> <p>Many locals are cautious despite the claim that the dye is mostly harmless.</p> <p>One user wrote on a Facebook page for Cronulla locals that dye was “legal to use in a stormwater drain”.</p> <p>“Doesn’t look good whatever it is,” another responded, while other cautious residents replied that they wouldn’t swim in the area until the dye fully dissipates.</p> <p><em>Images: Facebook</em></p>

Lisa Wilkinson denies turning to senior politicians over Higgins’ rape allegations

<p>Channel 10 personality and former <em>The Project </em>host Lisa Wilkinson has denied claims that she approached senior level politicians with a request to pose questions about Brittany Higgins’ rape allegations against Bruce Lehrmann during Question Time. </p> <p>The dismissal came in the wake of Channel 7’s <em>Spotlight </em>episode featuring the formerly accused, where a recording of a phone call between Wilkinson, her producer Angus Llewellyn, Higgins, and Higgins’ partner David Sharaz was exposed.</p> <p>During the conversation, which was recorded in January 2021, they were reportedly discussing which politicians they might be able to work with to steer the conversation in parliament, with Wilkinson telling Higgins that she wanted to see her “enunciate the fact that this place [Parliament House] is all about suppression of people’s natural sense of justice”. </p> <p>Sharaz noted that he had a “friend in Labor”, and that Senator Katy Gallagher could “probe and continue it [the conversation] going”. At one stage, Wilkinson went so far as to claim that “certainly Albo” should be considered, though she later went on to retract that, and suggested “Tanya Plibersek, definitely”. </p> <p>And while Sharaz had questioned what Wilkinson hoped to gain from the conversation, Wilkinson assured them that that wasn’t the case. </p> <p>“No. Whether it’s white privilege, male domination, whether it’s, you know, criminal activity. I am from the western suburbs of Sydney. I have always been motivated by exactly the same thing, people who deserve to be heard not being heard,” she explained. </p> <p>Wilkinson had more to say on the matter when it came to the likes of former deputy Liberal leader Julie Bishop, sharing her frustration about the “many opportunities” she had to “speak out against the culture”. </p> <p>“The minute she was out of there [she said], ‘oh it’s really sexist’,” Wilkinson added. “I tried to get her on the record with that so many times when she could’ve actually effected change, and she wouldn’t.”</p> <p>And now, despite the leaked recording - which was handed over by Channel 10 under subpoena during the criminal trial, with more shared on TV than in court - Wilkinson has released a statement to declare that she did not approach the politicians in question. </p> <p>“Nor did I speak to any other politicians, their minders or apparatchiks,” she said.</p> <p>The audio came up during Sunrise as well, when Natalie Barr asked their entertainment commentator, Peter Ford, whether or not the recording might be a problem down the line. </p> <p>“Was that coaching?” she asked. “Or was that a journalist talking before the interview?”</p> <p>Ford agreed that it was a fine line, then added, “but I generally think when someone says, ‘I don’t want to put words in your mouth,’ that is exactly what they want to do.”</p> <p><em>Images: Getty</em></p>

6 movie stars who turned down Oscar-winning roles

<p>The Academy Awards is unarguably the most prestigious and sought after award in the movie industry. Actors must carefully select the scripts that will advance their careers and highlight their acting skills. Although the movie stars below have had successful careers in Hollywood, here are the times the roles they walked away from ended up receiving the prestigious golden statuette.</p> <p><strong>1. Julia Roberts</strong></p> <p>Julia Roberts was offered the role of Viola de Lesseps in <em>Shakespeare in Love</em> which took Best Picture in the Academy Awards in 1998. <em>People</em> reported that Julia was one contract away from starring in the film when she found out that Daniel Day-Lewis turned down the role. Julia wanted Daniel to play the role of Bard of Avon so when he turned down the role, she decided to pull out. Gwyneth Paltrow was then given the role and ended up winning an Oscar for Best Actress for the film.</p> <p><strong>2. Harrison Ford</strong></p> <p>Harrison Ford has made a great name for himself in Hollywood. He won an Oscar for his role in <em>The Fugitive</em> and has played two of the greatest action heroes of all time, Hans Solo and Indiana Jones. Harrison could have had one more Oscar on his shelf had he not turned down the offer to act in <em>Syriana</em>. Harrison was offered the role of CIA Agent Robert Barnes but declined the role as he “didn’t feel strongly enough about the truth of the material.” George Clooney ended up with the role and won Best Supporting Actor in 2006. After watching the film, Harrison changed his mind on the film as the issues he had with the material were rectified.</p> <p><strong>3. Gregory Peck</strong></p> <p>Gregory Peck had been nominated for an Oscar four times before he took home Best Actor in 1963 for his portrayal of Atticus Finch in <em>To Kill a Mockingbird</em>. Gregory might have taken home an Oscar sooner had he not passed on the offer to star in <em>High Noon</em>. Gregory passed on the role as he had just starred in a western <em>The Gunfighter</em> and wanted to avoid typecasting. The role was then offered to Gary Cooper who won the Oscar for Best Actor for his performance. Gregory later said, "I don't think I would have been as good as Gary Cooper but I still think it would have been a good film with me in it."</p> <p><strong>4. Gwyneth Paltrow</strong></p> <p>In 2016, <em>The Danish Girl</em> received three nominations and one win at the Academy Awards. The film, however, had been stuck in the development stages for years as actors and directors continually abandoned the project. The role of Gerda Wegner, Lili’s wife, moved from Charlize Theron to Gwyneth Paltrow. Gwyneth was ready to star in the film when a last-minute shooting location changed the actress’ mind. As she didn’t want to spend too much time away from her kids, Gwyneth decided to walk away from the role. Tom Hooper, Eddie Redmayne and Alicia Vikander came on board with the project years later. Alicia played Gerda and won an Oscar for Best Supporting Actress.</p> <p><strong>5. Anne Hathaway</strong></p> <p>In 2013, Jennifer Lawrence won her first Oscar for Best Actress for playing Tiffany Maxwell in <em>Silver Linings Playbook</em>. Even though Jennifer was outstanding in the film, she wasn’t the first pick for the role. Film executive Harvey Weinstein admitted that Anne Hathaway was slated for the lead female role and Bradley Cooper’s role was meant for Mark Wahlberg. Both actors were ready to star in the film until Anne had some “creative differences” with director David O. Russell. The differences couldn’t be resolved so Anne left the project and Mark Wahlberg followed her. Anne Hathaway did end up winning an Oscar that year for Best Supporting Actress in <em>Les Miserables.</em></p> <p><strong>6. Paul Bettany</strong></p> <p>The portrayal of George Vi in <em>The King’s Speech</em> was not originally intended for Colin Firth. Screenwriter David Seidler believed Paul Bettany was perfect for the role and Paul was offered the part but declined as he didn’t want to be separated from his family for a long period of time. Paul had been working for five months so decided to go home to his family instead of working on a new film in Buckingham Palace. Reflecting on his decision to walk away from the role Paul said, “I regret not working with such amazing, amazing actors and directors and writers. But no, I have to do the right by my family every time.” Colin Firth was chosen for the role and in 2011, he won Best Actor in this film.</p> <p><em>Images: Getty</em></p>

Turning down the volume of pain – how to retrain your brain when you get sensitised

When faced with possible threats, the feeling of pain develops in a split second and can help us to “detect and protect”. But over time, our nerve cells can become over-sensitised.

Sensitisation can contribute to chronic pain conditions like fibromyalgia, irritable bowel syndrome, migraine or low back pain.</p> <p>But it might be possible to retrain our brains to manage or even reduce pain.</p> <h2>‘Danger!’</h2> <p>Our body senses possible threats via nerve endings called <a href="https://www.sciencedirect.com/topics/neuroscience/nociceptor">nociceptors</a>. We can think of these like a microphones transmitting the word “danger” through wires (nerves and the spinal cord) up to a speaker (the brain). If you sprain your ankle, a range of tiny chemical reactions start there.</p> <p>When sensitisation happens in a sore body part, it’s like more microphones join in over a period of weeks or months. Now the messages can be transmitted up the wire more efficiently. The volume of the danger message gets turned way up.</p> <p>Then, in the spinal cord, chemical reactions and the number of receptors there also adapt to this new demand. The more messages coming up, the more reactions triggered and the louder the messages sent on to the brain.</p> <p>And sensitisation doesn’t always stop there. The brain can also crank the volume up by making use of more wires in the spinal cord that reach the speaker. This is one of the proposed mechanisms of central sensitisation. As time ticks on, a sensitised nervous system will create more and more feelings of pain, seemingly regardless of the amount of bodily damage at the initial site of pain.</p> <p>When we are sensitised, we may experience pain that is out of proportion to the actual damage (<a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/hyperalgesia">hyperalgesia</a>), pain that spreads to other areas of the body (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4327510/">referred pain</a>), pain that lasts a long time (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5573040/">chronic or persistent pain</a>), or pain triggered by harmless things like touch, pressure or temperature (<a href="https://www.ncbi.nlm.nih.gov/books/NBK537129/#:%7E:text=Allodynia%20is%20defined%20as%20%22pain,produce%20sensation%2C%20causing%20pain.">allodynia</a>).</p> <p>Because pain is a biopsychosocial experience (biological and psychological and social), we may also feel other symptoms like fatigue, mood changes, sleep problems or difficulty concentrating.</p> <h2>Neuroplasticity</h2> <p>Around the clock, our bodies and brain are constantly changing and adapting. <a href="https://www.ncbi.nlm.nih.gov/books/NBK557811/">Neuroplasticity</a> is when the brain changes in response to experiences, good or bad.</p> <p>Pain science research suggests we may be able to <a href="https://www.nih.gov/news-events/nih-research-matters/retraining-brain-treat-chronic-pain">retrain</a> ourselves to improve wellbeing and take advantage of neuroplasticity. There are some promising approaches that target the mechanisms behind sensitisation and aim to reverse them.</p> <p>One example is <a href="https://pubmed.ncbi.nlm.nih.gov/21306870/">graded motor imagery</a>. This technique uses mental and physical exercises like identifying left and right limbs, imagery and <a href="https://www.physio-pedia.com/Mirror_Therapy">mirror box therapy</a>. It has been <a href="https://www.tandfonline.com/doi/full/10.1080/24740527.2023.2188899">tested</a> for conditions like <a href="https://www.ninds.nih.gov/health-information/disorders/complex-regional-pain-syndrome">complex regional pain syndrome</a> (a condition that causes severe pain and swelling in a limb after an injury or surgery) and in <a href="https://www.ncbi.nlm.nih.gov/books/NBK448188/#:%7E:text=Phantom%20limb%20pain%20is%20the,underlying%20pathophysiology%20remains%20poorly%20understood.">phantom limb pain</a> after amputation. Very gradual exposure to increasing stimuli may be behind these positive effects on a sensitised nervous system. While results are promising, more research is needed to confirm its benefits and better understand how it works. The same possible mechanisms of graded exposure underpin some recently developed <a href="https://mhealth.jmir.org/2019/2/e13080/">apps</a> for sufferers.</p> <p>Exercise can also retrain the nervous system. Regular physical activity can <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01317.2012">decrease the sensitivity</a> of our nervous system by changing processes at a cellular level, seemingly re-calibrating danger message transmission. Importantly, exercise doesn’t have to be high intensity or involve going to the gym. Low-impact activities such as walking, swimming, or yoga can be effective in reducing nervous system sensitivity, possibly by providing new evidence of perceived <a href="https://doi.org/10.1097/j.pain.0000000000002244">safety</a>.</p> <p>Researchers are exploring whether learning about the science of pain and changing the way we think about it may foster self-management skills, like pacing activities and graded exposure to things that have been painful in the past. Understanding how pain is felt and why we feel it <a href="https://doi.org/10.1111/1756-185X.14293">can help</a> improve function, reduce fear and lower anxiety.</p> <figure><iframe src="https://www.youtube.com/embed/eakyDiXX6Uc?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>But don’t go it alone</h2> <p>If you have chronic or severe pain that interferes with your daily life, you should consult a health professional like a doctor and/or a pain specialist who can diagnose your condition and prescribe appropriate active treatments.</p> <p>In Australia, a range of <a href="https://aci.health.nsw.gov.au/__data/assets/pdf_file/0003/212772/ACI-chronic-pain-services.pdf">multidisciplinary pain clinics</a> offer physical therapies like exercise, psychological therapies like mindfulness and cognitive behavioural therapy. Experts can also help you make lifestyle changes to improve <a href="https://painhealth.csse.uwa.edu.au/pain-module/sleep-and-pain/">sleep</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8584994/">diet</a> to manage and reduce pain. A multi-pronged approach makes the most sense given the complexity of the underlying biology.</p> <p>Education could help develop <a href="https://www.sciencedirect.com/science/article/abs/pii/S0738399121006467">pain literacy and healthy habits</a> to prevent sensitisation, even from a young age. Resources, such as children’s books, videos, and board games, are being developed and tested to improve <a href="https://doi.org/10.1016/j.jpain.2022.07.008">consumer and community understanding</a>.</p> <p>Pain is not a feeling anyone should have to suffer in silence or endure alone. <!-- Below is The Conversation's page counter tag.
