Original Bee Gees star passes away aged 78

Colin ‘Smiley’ Petersen has passed away aged 78. News of his death was posted on the official Facebook page of tribute band Best of the Bee Gees. “It is with a heavy heart we announce the passing of our dear friend Colin ‘Smiley’ Petersen,” they began. “He enriched our lives and bound our group with love, care and respect. “Not sure how we can go on without his glowing smile and deep friendship. We love you Col. Rest in Peace.” Petersen who was one of the original members of Australian band Bee Gees was born in Kingaroy, Queensland, has been credited for contributing to the band's rise to global superstardom. He was the band's first drummer and performed some of their most beloved songs including Massachusetts, To Love Somebody and Words. Petersen attended the same school in Redcliffe, Queensland as bandmates and brothers Barry Robin and Maurice Gibb, where he first developed an interest in music. After graduating, Petersen moved to the UK to break into the film industry, before he joined the Bee Gees in the 60's becoming the first non-Gibb brother to join the group. “There was an understanding that when the Gibbs’ arrived in England, that if the film thing didn’t work out, I’d join their band,” Petersen told Geelong Independent in 2022. “So I became the fourth Bee Gee, and that was obviously a big turning point in my life.” He left the band after the first phase of their career, just before they reached peak stardom in the '70s disco era, due to conflicts with the group's then-manager Robert Stigwood. Petersen moved back to Australia with his family in 1974, and in 2019 he joined the tribute group Best of the Bee Gees. His death comes after Maurice's sudden death in 2003, which prompted the Bee Gees to retire after 45 years. Robin later died in 2012 aged 62, leaving Barry, Vince Melouney and Geoff Bridgford as the last surviving members of the group. Petersen is survived by his ex-wife Joanne Newfield and their sons Jaime, born in 1971, and Ben, born in 1976. Image: Everett Collection/ Shutterstock Editorial

Beloved Friends, Tootsie and Mr Mom star passes away

Teri Garr, the beloved actress known for her iconic roles in classic films such as Young Frankenstein and Tootsie and her appearances on Friends, has passed away at the age of 79. Her death, confirmed by her publicist Heidi Schaeffer, occurred on Tuesday in Los Angeles, surrounded by family and friends. Garr's passing follows a long battle with multiple sclerosis, a condition she publicly disclosed in 2002 to raise awareness about the disease and its impact on daily life. Born Terry Ann Garr in Lakewood, Ohio, in 1944, Teri grew up in a theatrical family; her father was a vaudeville performer and her mother a Rockette. This background set the stage for Garr's early career, which began as a background dancer in Elvis Presley films during the 1960s. Her breakout role came in 1974 when she starred as Inga, the charming lab assistant to Gene Wilder's character in Mel Brooks' Young Frankenstein. The film became a cornerstone of American comedy, showcasing Garr's unique blend of humour and warmth. Garr further solidified her place in cinematic history with her performance in Tootsie in 1982, where she portrayed the vulnerable actress friend of Dustin Hoffman’s character. This role earned her an Academy Award nomination for Best Supporting Actress. Critics praised her ability to balance comedy with emotional depth, with film critic Pauline Kael calling her "the funniest neurotic dizzy dame on the screen" at that time. Despite her success, Garr faced significant challenges due to her health. She was diagnosed with multiple sclerosis during the filming of Tootsie, a struggle she detailed in her memoir, Speedbumps: Flooring It Through Hollywood. In it, she described MS as a "sneaky disease," one that complicated her life and career but did not define it. “My body had a trick or two up its sleeve," she wrote. "A stumble here, a tingling finger there. I was trained as a dancer and knew better than to indulge the random aches and pains that visited now and then. Being a successful Hollywood actress may be challenging, but little did I know that the very body that had always been my calling card would betray me.” Garr became an advocate for the National Multiple Sclerosis Society, using her platform to inspire others facing similar challenges. Throughout her career, Garr appeared in over 140 film and TV projects. She was known for her roles in Mr. Mom, Close Encounters of the Third Kind, and various television shows including Friends, where she played Phoebe's birth mother. Her playful spirit and comedic timing made her a favourite among audiences and fellow actors alike. In recent years, Garr had limited her appearances due to health issues but remained an influential figure in Hollywood. Tributes have poured in from fans and colleagues alike, celebrating her legacy as a pioneer for women in comedy and an inspiration for those battling chronic illnesses. Teri Garr leaves behind a rich legacy filled with laughter and heart. She is survived by her daughter Molly O'Neil and grandson Tyryn. Her contributions to film and television will be remembered fondly by generations to come. Images: CNN \ Fox Studios

One Direction star passes away aged 31

Former One Direction star Liam Payne has reportedly been found dead outside a hotel in Buenos Aires, in Argentina, according to local newspaper La Nacion. The 31-year-old is believed to have fallen from the third floor of a hotel at around 5pm local time the newspaper said, citing emergency services. According to La Nacion the local police station was called by the hotel manager who reported "an aggressive man who could be under the influence of drugs or alcohol". It is reported that Payne fell from around 13 or 14 metres and suffered "very serious injuries incompatible with life." Alberto Crescenti, head of the state emergency medical system SAME (El Sistema de Atención Médica de Emergencias), told local TV that Payne had fallen into a courtyard of the Casa Sur Hotel in the Palermo neighbourhood. “At 17.11, a SAME team arrived and confirmed the man’s death. We later learned that he was a singer in a musical group. “Unfortunately, he had injuries incompatible with life as a result of his fall, so we had to confirm his death. There was no possibility of resuscitation.” Payne was one of the founding members of One Direction, one of the most loved boy bands of the past decade. He auditioned first as a solo act for the UK reality series The X Factor in 2008, before being eliminated. In 2010 he auditioned again and was grouped with Harry Styles, Niall Horan, Louis Tomlinson and Zayn Malik by the judges to form One Direction. Image: SplashNews.com/ Shutterstock Editorial

How do I know when it’s time to replace my running shoes?

<a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Any runner will tell you there’s nothing better than slipping on a brand new pair of shoes. But how regularly should runners fork out hundreds of dollars on their next pair? Conventional wisdom tells us the average lifespan of a running shoe is around 500 to 800 kilometres. But where did this advice come from, and is it based on science? Some evidence comes from <a href="https://doi.org/10.1177/0363546585013004">impact testing</a> with machines designed to simulate the shoe repeatedly contacting the ground during running. Other evidence comes from <a href="https://doi.org/10.1080/19424280.2010.519348">monitoring runners who have used shoes in the real world</a> for long periods. This research is often focused on shoe materials and structure. But we think more compelling markers for the runner are shoe comfort, performance benefit and injury risk. Rather than seeking a “one-size-fits-all” answer to how many kilometres your shoes should be limited to, it’s also better to consider individual signs based on your shoe type and its purpose. <h2>The three signs to watch for</h2> Runners tend to replace their shoes for three main reasons: <ol> <li>they believe their performance is being negatively impacted</li> <li>their shoes are leading to some bodily discomfort which may cause (or has already caused) an injury</li> <li>the shoes are no longer comfortable or “feel” as good as they used to.</li> </ol> So what does the evidence say about these factors? <h2>Performance</h2> Some shoe material properties do contribute to enhanced running efficiency. Degrading these materials by racking up the kilometres may hinder peak performance on race day. This is most clearly seen in carbon fibre plate shoes used by modern elite runners to achieve <a href="https://doi.org/10.1007/s40279-020-01420-7">rapid road race times</a>. The design features <a href="https://doi.org/10.1007/s40279-018-1024-z">thought to drive this</a> are the combination of highly compliant and resilient midsole foam and a stiff embedded carbon fibre plate, which support energy storage and return. Runners will typically “save” these shoes for race day and replace them after fewer kilometres, compared to conventional running shoes. The available research does support the <a href="https://doi.org/10.1007/s40279-017-0811-2">performance benefits of these shoes</a>. However, it’s not known how long the benefits last relative to kilometres of wear. To our best knowledge, there’s only one study on running performance and shoe wear, but unfortunately it did not involve carbon fibre plate shoes. A University of Connecticut 2020 <a href="http://hdl.handle.net/11134/20002:860659513">master’s thesis</a> investigated eight college-level runners over 400 miles (643km) of Nike Pegasus shoe use. Large reductions in running economy were reported at 240km, and this was statistically significant at 320km. No reduction was observed at 160km. So, if you’re chasing personal best times, the evidence above suggests that for peak performance, shoes should be replaced somewhere between 160 and 240km (although this is not directly based on carbon fibre plate shoe research). It appears that minimising training kilometres for your favourite racing shoes – keeping them “fresh” – could contribute to peak performance on race day, compared to racing in a pair of old shoes. <h2>Injury or discomfort</h2> The link between shoe wear and injury is unclear, and based on <a href="https://bjsm.bmj.com/content/37/3/239">minimal and often conflicting evidence</a>. One study did find that <a href="https://doi.org/10.1111/sms.12154">runners who alternate their running shoes</a> have a lower risk of injury than runners who run only in the same pair of shoes over a 22-week period. Runners who alternated shoes throughout the study period would have accumulated less wear in each shoe. This provides some support for the notion that accumulating too many kilometres in your shoes may increase risk of injury. Unfortunately, the exact age of running shoes was not reported in this study. However, based on the running characteristics reported, the single-shoe pair users completed an average of 320km in their shoes (after adjusting for a small fraction who had to replace shoes during the study). This was compared to the multi-shoe pair users who used an average of 3.6 pairs of shoes, ran more total kilometres, but accumulated an average of only 200km per shoe pair. <h2>Comfort</h2> Comfort and fit are the <a href="https://www.tandfonline.com/doi/full/10.1080/19424280.2024.2353597#abstract">two most important factors</a> to runners when selecting running shoes. Evidence linking improved shoe comfort to <a href="https://journals.lww.com/acsm-msse/fulltext/2001/11000/relationship_between_footwear_comfort_of_shoe.21.aspx">reduced injury rates</a> or <a href="https://www.tandfonline.com/doi/full/10.1080/17461391.2019.1640288">improved running economy</a> is mixed, but reducing harms from poorly fitting and uncomfortable shoes is clearly a priority for runners. Most <a href="https://commons.nmu.edu/isbs/vol35/iss1/293/">runners land on their heel</a>. The repeated compression of the midsole causes the material to harden, possibly after as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5534152/pdf/ijspt-12-616.pdf">little as 160km</a>, according to one study from 2017. However, there was virtually no change in the amount of cushioning runners perceived under their heel after 160km. Even after using the shoes for 640km, they felt little difference – about 3%. While at first this might seem like runners are not very good at judging when shoes lose their cushioning, it also tells us changes in perceived shoe cushioning are very gradual and may not be important for runners until they reach a certain threshold. This amount will differ from person to person, and from shoe to shoe, but research suggests it’s not until perceived cushioning reaches about a <a href="https://www.tandfonline.com/doi/full/10.1080/02640414.2020.1773613?casa_token=P87vatZhOlgAAAAA%3ACu11TZmGjKc1xYsaUlEVfWvZDvcSnx3qgKL1E2DsRYwf6hMvBiyVAm-M_-4Iauq4lwHna0QMu1IRmw">10% change</a> that runners consider it meaningful. We must be careful when applying these findings to the latest running shoes which use newer materials. But you can use it as a rule of thumb – once you notice a drop in comfort, it’s time to get a new pair. <h2>When to choose new shoes</h2> Ultimately, there’s no one simple answer for when you should get new running shoes. You may also not keep close track of how many kilometres your favourite pair has racked up. Overall, we believe the most practical advice is to keep your racing shoes “fresh” (under 240km), alternate a couple of other pairs during regular training, and replace them when you detect a notable drop in comfort.<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/238997/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/john-arnold-178470">John Arnold</a>, Senior lecturer, Sport & Exercise Biomechanics, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> and <a href="https://theconversation.com/profiles/joel-fuller-2210202">Joel Fuller</a>, Senior Lecturer, Department of Health Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I’m feeling run down. Why am I more likely to get sick? And how can I boost my immune system?

Stress is an inevitable part of life. In short bursts, our stress response has evolved as a survival mechanism to help us be more alert in <a href="https://theconversation.com/no-you-cant-blame-all-your-health-issues-on-high-cortisol-heres-how-the-hormone-works-203162">fight or flight situations</a>.

Once you begin to feel sick, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465119/">stress response</a> rises, making it harder for the immune system to fight off the disease.

Initially, circulating immune cells detect and flock to the site of <a href="https://www.nature.com/articles/ni1275">infection</a>.

Heartbreaking final message as world's oldest woman passes away

Maria Branyas Morera, the world's oldest woman, has died aged 117. The centurion, who has lived through two world wars and a global pandemic, passed away “peacefully and without pain”, according to her family members who announced her tragic passing on X, formerly Twitter. “Maria Branyas has left us. “She died as she wished: in her sleep, peacefully and without pain. “We will always remember her for her advice and her kindness.” In a heartbreaking final message shared to X on Tuesday, Morera shared that she felt "weak" and that the "time is near". “The time is near. Don’t cry, I don’t like tears. And above all, don’t suffer for me," she wrote. “Wherever I go, I will be happy.” Morera became the world's oldest living person after French nun Lucile Randon passed away aged 118 in January last year. Before her death, Morera agreed to undergo scientific testing by researchers who collected samples of her saliva, blood and urine, in hopes to gain insight into the secrets to a long life. They will compare them with those of her 80-year-old daughter and hope that by studying her genes they may develop drugs which could combat diseases associated with ageing. Morera is survived by her two daughters, 11 grandchildren and 11 great-grandchildren. Images: news.com.au/ Guinness Book of Records

"We should give back": Bill Gates' ex-wife on giving away her $16bn fortune

Melinda French Gates has opened up on her decision to give away her fortune after leaving the Bill & Melinda Gates Foundation in June. Melinda, who is reportedly worth $16.8 billion, said that she will stick with her decision to give away her fortune on The Late Show with Stephen Colbert, as it's "the right thing to do for society". "If we grew up in the United States, anybody who has grown up in this country has been really lucky and I don't care who you are," she explained. "To be able to go to a decent school, grow up and pursue your career, and if so you are a billionaire, my gosh, you have benefited from this country, right? "So we should give back." She also feels there is "a responsibility and to do it in a way that's incredibly thoughtful". Melinda, who divorced the Microsoft founder Bill Gates back in 2021, has announced her plans to focus on her organisation Pivotal Ventures, which she founded in 2015. The organisation's aim is to "advance social progress by removing barriers that hold people back." She said that she is determined to ensure that "women's rights are not only on the agenda, but that women are setting the agenda" – especially after watching women's rights be rolled back internationally over the last few years." "What I saw, part of why our women's rights got rolled back in the United States is that those organisations were starved for funding, and they were playing defense," she explained. Melinda has pledged to donate $1 billion to this end over the next two years. Image: Julien De Rosa/EPA/ Shutterstock Editorial

Shelley Duvall passes away at 75

Shelley Duvall who starred in Stanley Kubrick's iconic horror film The Shining has passed away aged 75. Duvall died in her sleep on Thursday at her home in Bianco, Texas, after diabetes complications according to her friend and publicist Gary Springer. Her longtime partner, Dan Gilroy shared a heartbreaking statement. "My dear, sweet, wonderful life, partner, and friend left us last night," he said. "Too much suffering lately, now she's free. Fly away beautiful Shelley." Known for her thin physique, large expressive eyes and powerful performances, Duvall was remembered for her standout roles alongside Jack Nicholson in The Shining and Robin Williams in the comedy Popeye. She became Robert Altman's protégé after she was spotted by his staff members at a party in Houston, Texas in 1970, where she attended junior college, and Altman was preparing to film Brewster McCloud at the time. She also played memorable roles in some of his other films, including Nashville in 1975 and 3 Women in 1977, which won her the Cannes Best Actress Award. "He offers me damn good roles," Duvall said about Altman for The New York Times in 1977. "None of them have been alike. He has a great confidence in me, and a trust and respect for me, and he doesn't put any restrictions on me or intimidate me, and I love him. I remember the first advice he ever gave me: 'Don't take yourself seriously.'" Despite The Shining being one of her greatest roles, filming it took an emotional toll on her, after having to be in hysterics during long days of filming, with one scene reportedly requiring 127 takes, By the 1990s she began retiring from acting and retreated from public life. "How would you feel if people were really nice, and then, suddenly, on a dime, they turn on you?" Duvall told the Times earlier this year. "You would never believe it unless it happens to you. That's why you get hurt, because you can't really believe it's true." Images: Soshellyduvall Instagram

Walking or running: for the same distance, which consumes more energy?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clement-lemineur-1529211">Clément Lemineur</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>; <a href="https://theconversation.com/profiles/clement-naveilhan-1495411">Clément Naveilhan</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a>, and <a href="https://theconversation.com/profiles/francois-dernoncourt-1495410">François Dernoncourt</a>, <a href="https://theconversation.com/institutions/universite-cote-dazur-2917">Université Côte d’Azur</a> It’s Monday morning, the alarm goes off and it’s already 7:30 a.m. – and you’re 30 minutes late. Normally you need 45 minutes to walk the 3 kilometres to work, but this morning you’ll be running for 20 minutes. Yes, but by lunchtime you’re feeling more tired and you have the impression that you’ve expended more energy than usual on the trip. Yet you’ve covered the same distance as on the other days. How can this be? The calorie expenditure associated with any activity is called the “metabolic cost”, and corresponds to the energy consumed by our organs to cover a given distance. This metabolic cost can be determined by analysing the oxygen our bodies consume and the carbon dioxide they produce, we can estimate the amount of energy expended, and thus the metabolic cost. It was using this method that <a href="https://pubmed.ncbi.nlm.nih.gov/692303/">researchers had already answered our question back in the 1970s</a>. Perhaps not surprisingly, running consumes more energy than walking for the same distance covered. But why? <h2>Energy lost when running</h2> Imagine you’re watching someone running. Now look closely at the vertical movement (up and down) of their pelvis and head. As you can see from the diagram below, when we run, the distance that our body moves up and down is greater than when we walk. To produce this vertical movement, the muscles of the lower limbs have to generate more force, and that consumes more energy, yet doesn’t bring us any closer to our destination. So when running, part of the energy expended is used to move our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/16029949/">upward rather than forward</a>. The energy needed to cover those 3 km is therefore higher for running than for walking. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.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/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=287&fit=crop&dpr=1 600w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=287&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=287&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=361&fit=crop&dpr=1 754w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=361&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/602769/original/file-20240625-18-xilv63.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=361&fit=crop&dpr=3 2262w" alt="Illustration of the oscillations of running and walking" /></a><figcaption>Running involves much greater vertical oscillation of the centre of mass than walking. This is the main reason why running consumes more energy than walking for the same distance covered. François Dernoncourt, Fourni par l'auteur</figcaption></figure> This difference between walking and running is not confined to what happens during the activity itself. In fact, each physical exercise causes a delayed expenditure of energy, which is added to the expenditure during the activity. Taking this into account, it’s once again running that uses more energy than walking. Immediately after running your 3 km, the increased energy consumption (compared with resting) lasts for several minutes, mainly because of the increase in body temperature and the replenishment of energy reserves. This additional expenditure after running is <a href="https://pubmed.ncbi.nlm.nih.gov/22446673/">more than twice that observed after walking</a>, due to the difference in intensity between the two exercises. <h2>It all depends on speed</h2> Running therefore involves a higher calorie expenditure than walking for the same distance covered. But this is on condition that the walking speed considered is “normal” (around 5 km/h). So, if we walk very slowly, it will take us so long to cover the 3 km that the calorie expenditure will be greater in the end. This is because the body expends a certain amount of energy per unit of time no matter what, regardless of the activity performed (known as the “basal metabolic rate”). The same applies if the walking speed is very fast (<a href="https://pubmed.ncbi.nlm.nih.gov/29925582/">more than 8 km/h</a>): running is more energy-efficient. Here, the coordination required to walk at such a speed means that we need to activate our muscles more, without being able to take advantage of the elasticity of our tendons, as is the case with running. Moreover, we have a very precise intuitive perception of the energy efficiency of a particular style of movement. If we’re on a treadmill whose speed gradually increases, the point at which we spontaneously switch from walking to running coincides with the <a href="https://www.sciencedirect.com/science/article/pii/S096663622100120X">moment when it would become more energy-consuming to walk than to run</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.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/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=395&fit=crop&dpr=1 600w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=395&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=395&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=497&fit=crop&dpr=1 754w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=497&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/604700/original/file-20240703-17-4dlrj.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=497&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Modelling of metabolic cost (kilocalories expended per kilogram per kilometre covered) as a function of speed (kilometres per hour) for walking and running.

Take my (bad) breath away – causes of halitosis and how to check whether you have it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> In Greek mythology, the many-headed beast <a href="https://mythopedia.com/topics/hydra">Hydra</a> had such severe <a href="https://patient.info/oral-dental-care/bad-breath-halitosis">halitosis</a> that the stench of its breath was deadly to anyone who smelled it. Thankfully, our morning breath might not be that pungent – although eating <a href="https://www.healthline.com/health/get-rid-of-garlic-onion-breath">onions or garlic</a> can put some people in competition with the Hydra. Halitosis has many causes (aside from poor oral hygiene) and can indicate problems with the gut, the sinuses and even the bloodstream. In fact, breath samples can even be tested to make formal diagnoses of health conditions. One condition that can affect the smell of breath is <a href="https://www.diabetes.org.uk/">diabetes mellitus</a>. This is a metabolic disorder where sugar (glucose) is unable to access the body’s cells where it is needed to provide energy, and so rises in the bloodstream. In some instances, such as insufficient insulin dosing, or infection, the body’s response is to break down fats into compounds called ketones to act as a rapid form of fuel. This serious condition is called <a href="https://www.nhs.uk/conditions/diabetic-ketoacidosis/">diabetic ketoacidosis</a>. Ketones have a distinctive scent. <a href="https://www.gov.uk/government/publications/acetone-properties-and-incident-management/acetone-general-information">Acetone</a>, which is also an ingredient in some nail varnish removers, is one of these ketones and has the smell of pear drops. When ketones build up in the bloodstream they easily <a href="https://iopscience.iop.org/article/10.1088/0967-3334/32/8/N01/pdf">diffuse into the breath</a>, giving it a <a href="https://www.medicalnewstoday.com/articles/319683">fruity odour</a>. It’s not just diabetes that can trigger ketone production. <a href="https://pubmed.ncbi.nlm.nih.gov/36033148/">Some diets</a> are based on generating ketones from the breakdown of fats to promote weight loss. These methods, such as the <a href="https://www.healthline.com/nutrition/atkins-diet-101">Atkins diet</a>, force the body to convert fat into energy by restricting carbohydrates. <figure><iframe src="https://www.youtube.com/embed/5U8IDO1fHlU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Other diets based on the same principles include the <a href="https://patient.info/healthy-living/weight-loss-weight-reduction/52-diet">5:2</a> intermittent fasting diet. On this diet, followers restrict food intake on two days of the week to significantly reduce calorie consumption – and make the body produce ketones. These diets may help weight loss, but the side-effects can be grim. One of the most notorious side-effects is foul breath, although there are also anecdotal reports of <a href="https://www.forbes.com/sites/brucelee/2019/03/03/is-keto-crotch-really-a-side-effect-of-the-keto-diet/">“keto crotch”</a> where some followers of keto diets complain of strong genital odour. <h2>Bacteria and breath</h2> Another cause of bad breath is an <a href="https://iopscience.iop.org/article/10.1088/1752-7155/4/1/017003/pdf">overgrowth of bacteria</a> that produce foul smells. There are plenty of nooks and crannies in the mouth for bacteria to hide, grow and fester, especially the hard-to-clean areas – in between the teeth, and in and around the gums and tongue – or out-of-reach places, such as right at the back of the mouth and the throat. The throat acts as a passage for food, fluids and air. Some patients can develop a condition called <a href="https://www.entuk.org/patients/conditions/49/pharyngeal_pouch_surgery_new">pharyngeal pouch</a>. This is where a pocket forms at the back of the pharynx (the medical name for the throat) in which food and fluids can accumulate, ferment and give breath a pungent odour. Bacteria can also trigger infections in the mouth, like tonsillitis and tooth abscesses where tissues become inflamed, or develop purulence (production of pus). Pus is a collection of different dead cells, including bacteria, and it too can give off a putrid smell. Also, <a href="https://pubmed.ncbi.nlm.nih.gov/25234037/">sinusitis</a> – which is an infection of the air-filled cavities in the skull – can drip foul-smelling infected secretions into the throat, causing bad breath. <h2>Breath tests</h2> Doctors can test breath for bacteria to diagnose some health conditions. For example, <a href="https://pubmed.ncbi.nlm.nih.gov/28891138/">Helicobacter pylori</a>, bacteria that can irritate the gut and lead to the development of potentially dangerous ulcers, turns the compound urea into carbon dioxide. To test for H pylori, a <a href="https://www.nhs.uk/conditions/stomach-ulcer/diagnosis/">diagnostic breath test</a> is performed before and after dosing a patient with urea. If the patient exhales increased levels of carbon dioxide after being dosed with urea, then the test is positive. Breath can also be tested for an overgrowth of bacteria in the <a href="https://www.healthline.com/health/sibo">small intestine</a> (Sibo), which can lead to symptoms like abdominal pain and bloating. Sibo produces gases like hydrogen and methane that can also be detected with a breath test. If you’re worried about pongy breath and don’t have any medical issues, then you can <a href="https://www.healthline.com/health/dental-and-oral-health/how-to-smell-your-own-breath">test your own breath</a>. The age-old method is to lick the back of your wrist, let it dry and then have a sniff. You can also do the same with a tongue scraper, dental floss or a sample of breath exhaled into a cupped hand. <figure><iframe src="https://www.youtube.com/embed/ak5UEM8FK2s?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Often, we can become used to the smell of our own breath. We might only notice when it becomes really bad, or when there are other symptoms, like a foul taste in the mouth. Or when someone plucks up the courage to finally tell you that you have a case of the breath pongs. Suppose someone has broken the news – what do you do now? <a href="https://www.nhs.uk/conditions/bad-breath/">Simple measures can work well</a>, including regular fluid intake – <a href="https://www.dentalhealth.org/bad-breath">dry mouth</a> can lead to bad breath so make sure you’re drinking enough water – and good oral hygiene. This involves brushing the teeth, tongue and flossing between your teeth to eliminate any bacterial hot spots, as well as regular checkups at the dentist. Mouthwash can be an effective temporary solution but there’s evidence that a <a href="https://theconversation.com/eating-leafy-greens-could-be-better-for-oral-health-than-using-mouthwash-221181#:%7E:text=But%20research%20has%20indicated%20that,alternative%20for%20treating%20oral%20disease.">diet rich in leafy greens</a> might be even better at countering bad breath. Smoking is another potential underlying <a href="https://www.healthline.com/health/how-to-get-rid-of-cigarette-breath#1-brush-teeth">cause of halitosis</a>. So if you want sweeter breath, pack in the cigarettes – yet another good reason to give up.<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/231858/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Daughter of former All Black charged over alleged hit and run death

The daughter of former New Zealand All Black has been charged over an alleged hit and run that left a 65-year-old man dead in Auckland. Helena Jade Cribb, the daughter of Ron Cribb, was charged earlier this year after Jason Collins' body was found by a member of the public on O'Brien Rd, Lucas Heights in the early hours of December 7. The 22-year-old previously had a name suppression, which has now lapsed. Earlier this year, Detective Sergeant Ben Bergin said the driver allegedly involved had been identified not long after Collins' death. "A thorough investigation has been underway into the tragic circumstances by the Waitematā CIB and we have reached a point where charges have been filed," Bergin said. Collins has been remembered as a devoted father, husband and friend. "The tragic loss of Jason has left an unfillable void in our hearts," a statement on behalf of his family read. "...his absence is a constant ache, a relentless reminder of what we've lost. "Taken from us too soon, his departure is a profound and senseless blow that we struggle to comprehend. "Each day is a battle against the overwhelming emptiness left in his wake. "We ask for privacy at this time as we continue to grieve." The 22-year-old reportedly faces a charge of operating a vehicle carelessly, causing death while under the influence of alcohol or drugs. She is set to reappear in court in September.

“Grief eats you away”: Prince Harry's candid interview about losing his mother

Prince Harry has spoken candidly about his ongoing struggles with grief following the death of his mother, the late Princess Diana, when he was just 12 years old. Upon his brief return to the UK, the Duke of Sussex opened up in a new interview as part of his role as global ambassador for Armed Forces charity Scotty’s Little Soldiers, who work to support children who have lost parents in the military, admitting that “grief eats you away”. Harry detailed how difficult it was losing his mother at such a young age, admitting he spent nearly two decades “not thinking” about her death and was forced to eventually get help after years of “total chaos”. He added that learning how to celebrate a late loved one is difficult for a child, as it made them “sad”. “But realising if I do talk about it, and I’m celebrating their life, then things become easier,” he said. Harry went on, “You convince yourself that the person you’ve lost wants you, or you need to be sad for as long as possible to prove to them that they are missed … Especially when every defence mechanism in your mind, nervous system and everything else is saying ‘do not go there.” <iframe title="YouTube video player" src="https://www.youtube.com/embed/YY-W6VEXlZM?si=SBQyGGCKAOhELxlv" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe> "But then there’s this realisation of, no, they must want me to be happy”. The 39-year-old royal shared how, after decades of silent mourning, he learned suppressing grief was “in fact not” the best form of coping with loss. “It can be for a period of time,” he went on to say. “But…if you suppress this for too long, you can’t suppress it forever it’s not sustainable and it will east away at you inside." “Once realising that if I do talk about it and I’m celebrating their life then actually things become easier.” Image credits: YouTube

How do I plan for my retirement? Step one – start right away

<a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Planning for retirement is important because it will help you build the nest egg you’ll need to financially sustain your retirement years. Past <a href="https://www.tandfonline.com/doi/epdf/10.1080/03601277.2012.660859?needAccess=true">studies</a> have shown that those who plan for their retirement are more likely to be better off at retirement compared to those don’t. The sooner the planning process gets underway, the better. This gives your money more time to grow by generating investment returns. And the income from your first job is your first opportunity to save for retirement. As the saying goes: “The best time to plant a tree was 20 years ago. The second best time is now.” As people <a href="https://www.statssa.gov.za/?p=15601">can expect to live longer</a>, they must save more for retirement so that they don’t outlive their savings. This is particularly true given that the pensions landscape worldwide has undergone some major changes. In the past, governments and employers provided retirement income for individuals through government social security benefits and employment-based retirement funds. Because of increasing life expectancies, pension plans that guaranteed a retirement benefit to employees are now rare. Employees are now responsible for making contributions towards their own pensions as well as choosing the investments offered by the pension fund. Since employers are no longer responsible for funding their employees’ retirement and governments lack resources to provide a universal state pension, each person is ultimately responsible for ensuring they have enough retirement savings. So it’s very important to know the basics of the retirement planning process. As a researcher, I’m interested in how people use financial products to overcome economic challenges and build wealth. One of the things I investigate is whether planning for retirement leads to better retirement outcomes. For instance, my <a href="https://www.researchgate.net/profile/Bomikazi-Zeka-2/publication/340130176_Retirement_funding_adequacy_in_black_South_African_townships/links/5e8bf3924585150839c6408b/Retirement-funding-adequacy-in-black-South-African-townships.pdf?_sg%5B0%5D=started_experiment_milestone&origin=journalDetail&_rtd=e30%3D">research</a> has found that individuals whose financial affairs are in order are more likely to maintain their standard of living at retirement. Given that everyone’s financial situation is unique, it’s always a good idea to speak to a financial planner for tailored financial advice. If you haven’t given retirement planning much thought or don’t know where to start, here are four points to help get the ball rolling. <h2>What are my retirement goals?</h2> Retirement goals make you think about what you want to achieve by the time you retire and what you need to do to achieve it. Some people may have a goal in mind about when they want to retire, or how much wealth they’d like to have by the time they retire. And since wealth has different meanings for different people, others may think about maintaining or improving their standard of living at retirement. Once you’ve thought about your retirement goals, the <a href="https://corporatefinanceinstitute.com/resources/management/smart-goal/">“smart” goals</a> framework is a useful guide. It outlines that goals should be: specific, measurable, attainable, relevant and time-bound. When goals are clear, within reach, achievable, realistic and time-sensitive, they become a blueprint to help you turn them into a reality. <h2>How do I start saving for retirement?</h2> For those who have a job that comes with retirement fund membership, a workplace pension is used to provide for retirement. But there are also other options available to help you save. For instance, retirement annuity funds are voluntary retirement savings. Personal assets such as <a href="https://www.allangray.co.za/what-we-offer/unit-trust-investment/#fund-3">unit trusts</a> or <a href="https://www.gov.za/faq/money-matters/how-can-i-make-tax-free-investment">tax-free investments</a> can also be used as a savings tool. Unit trusts are generally better suited for people willing to take on risk because their value is tied to the movements of financial markets. In other words, they can generate positive returns but they can also lose value. The drawback of tax-free investments in South Africa is that they have a lifetime contribution limit. You can’t use them to save more than R500,000 (US$27,400). Each of these options has its advantages and disadvantages and what works best for one person may not be best for another. But there are several ways to save for retirement depending on your financial situation and retirement goals. Getting professional advice will help you determine what’s best for you. <h2>Will my retirement savings be enough?</h2> Once you’ve set your retirement goals and have a retirement savings plan in place, you can calculate whether you are saving enough to achieve your retirement goals. For example, if your retirement goal is: “I want to retire at the age of 65 years with an income equivalent to R35,000 (US$1,900) per month” then you can use a <a href="https://www.sanlam.co.za/tools/Pages/retirement.aspx">retirement calculator</a> to track your progress and determine whether you need to make adjustments to meet your goals. You might have to increase the monthly amount you’re putting away for retirement or reconsider your retirement age. The retirement calculators are also a useful tool for regular check-ins on your progress should your financial situation change – for example, if you change employers and earn a different salary. <h2>What other issues should I consider?</h2> It’s also important to think about your lifestyle and priorities. For instance: <ul> <li> do you aim to retire with your mortgage settled? </li> <li> are there debts you plan to clear before you retire or children who need financial support at retirement? </li> <li> would you like to renovate your home? </li> <li> would you like to buy a new car when you reach retirement age? </li> </ul> Another important consideration is healthcare costs. Many people assume that they will be able to work indefinitely and overlook the fact that healthcare costs may increase with age. <h2>Starting early matters</h2> Many people plan to work after retirement age, while others don’t plan to retire at all. It may be that they can’t afford to. They may have accessed their retirement benefits too soon, made inconsistent retirement fund contributions, or had to pay high administrative costs that eroded the final value of a retirement payout. So best be prepared. Retirement may seem like a distant event to plan and save for, especially when there are more pressing financial needs. It’s important to think about the financial decisions you make now that may cost you in the future. If you start to plan for your retirement now, your future self will thank you for it.<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/230553/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, Assistant Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Young and the Restless star passes away after cancer battle

Veteran soap opera actress Meg Bennett has died at the of 75 after a lengthy battle with cancer. According to <a href="https://www.hollywoodreporter.com/tv/tv-news/meg-bennett-dead-young-and-restless-1235878548/" target="_blank" rel="noopener">The Hollywood Reporter</a>, Bennett's family announced that she passed away on April 11th. Bennett had a prolific career in the world of soap operas as both a writer and actress, after working on high profile shows such as The Young and the Restless, General Hospital, Santa Barbara and many more. She became most known for her role on The Young and the Restless, appearing on 52 episodes from 1980–2020 playing the role of Julia Martin/Julia Newman, the spouse of Eric Braeden’s character Victor Newman. Bennett also had a stellar career on Broadway, appearing in the initial run of the musical Grease in 1972 playing the role of Marty Maraschino for more than two years. She also racked up a significant credit as a writer on a number of soaps, stepping behind the camera on The Young and the Restless after her character was phased out. In the interview in 1985, Bennett opened up about the differences in her approach to acting and writing. She said, "I'll admit, acting makes me a little crazy sometimes: You wait to audition. You wait for the part. When you're writing, you're in control. I can initiate things on my own when I'm writing." Bennett is survived by her spouse of 19 years Robert Guza Jr., as well as two stepdaughters, four grandchildren, a brother and a sister. Image credits: Getty Images

Legendary Star Wars and James Bond actor passes away

The galaxy far, far away has dimmed a little with the passing of Michael Culver, a distinguished British actor whose name became etched in the annals of cinematic history, particularly for his role in the iconic 1980 film Star Wars: Episode V - The Empire Strikes Back. Culver, who portrayed Captain Needa, the unfortunate Imperial officer, met his demise in one of the franchise's most memorable scenes at the hands of Darth Vader. However, his legacy extends far beyond the realms of science fiction, encompassing a career spanning over five decades of stage, screen and political activism. Born in 1938 in Hempstead, North London, to esteemed parents within the theatre industry, Culver was destined for a life under the spotlight. His father, Roland Culver, was a notable West End stage actor, while his mother, Daphne Rye, served as a casting director in London-based theatre. Following in their footsteps, Culver honed his craft at the London Academy of Music and Dramatic Art, laying the foundation for a prolific acting career. Culver's journey in the performing arts began in the late 1950s, with appearances on Broadway in Shakespearean classics such as King Henry V, Hamlet, and Twelfth Night. His talent soon graced the West End stage in 1962, marking the start of a distinguished theatrical career. Transitioning to the small screen, Culver made his onscreen debut in 1961, captivating audiences with his versatile performances in British television series and movies. However, it was Culver's portrayal of Captain Needa in The Empire Strikes Back that solidified his status as a cultural icon. Despite his character's brief appearance, Culver left an indelible mark on audiences worldwide, immortalised in one of cinema's most unforgettable moments. His confrontation with Vader, culminating in a chilling demise, remains etched in the memories of countless fans, a testament to Culver's ability to captivate audiences with his presence. Beyond his intergalactic exploits, Culver's talents graced a multitude of productions, including notable roles in Sherlock Holmes, A Passage to India, Secret Army, and even appearing in two James Bond movies – From Russia With Love and Thunderball – in uncredited roles. His versatility and dedication to his craft earned him admiration and respect from peers and audiences alike. Yet, Culver's contributions extended beyond the realms of entertainment; in the early 2000s, he shifted his focus to political activism, leveraging his platform to advocate for causes close to his heart. Despite bidding farewell to the limelight, Culver's legacy endures through the countless lives he touched and the memories he forged on stage and screen. An extended message on the Alliance Agents Facebook page, who represented Culver, read as follows: "We are very sad to confirm the passing of our friend and client Michael Culver. A career spanning over 50 years with notable roles in Sherlock Holmes, A Passage to India, Secret Army and of course one of the most memorable death scenes in the Star Wars franchise. Michael largely gave up acting in the early 2000's to concentrate his efforts into his political activism. It's been an honor to have represented Michael for for the last decade and to have taken him to some of the best Star Wars events in the UK and Europe. A real highlight was taking Michael to Celebration in Chicago in 2019. He was lost for words when he saw his queue line with nearly 200 people waiting to see him. We worked with Michael just 3 weeks ago at his last home signing with our friends at Elite Signatures. Michel died on Tuesday 27th February at the age of 85." "We miss him." His passing leaves a void in the hearts of fans and colleagues, a reminder of the fleeting nature of life's curtain call. As we reflect on his remarkable journey, let us celebrate the life and legacy of Michael Culver, an actor whose talents transcended galaxies and whose spirit will continue to inspire generations to come. In his memory, let us heed the timeless words of Captain Needa himself: "We shall double our efforts." Rest in peace, Michael Culver. The force will always be with you. Images: IMDB / Wookiepedia

Beloved Star Trek and Marvel star passes away at age 49

The entertainment world is mourning the loss of a talented actor and beloved individual, Kenneth Mitchell, who passed away at the age of 49 after bravely battling ALS for five years. Mitchell, recognised for his roles in notable productions such as Star Trek: Discovery and Captain Marvel, leaves behind a legacy that extends far beyond the screen. In a heartfelt statement shared through X and Instagram, Mitchell's family announced his passing, remembering him as a cherished father, husband, brother, uncle, son and dear friend. “With heavy hearts we announce the passing of Kenneth Alexander Mitchell, beloved father, husband, brother, uncle, son and dear friend,” his family wrote. “Ken was widely known as an actor in many films and television shows. He’s portrayed an Olympic hopeful, an apocalypse survivor, an astronaut, a superhero’s dad, and four unique Star Trekkers. “For five and a half years Ken faced a series of awful challenges from ALS. And in truest Ken fashion, he managed to rise above each one with grace and commitment to living a full and joyous life in each moment. “He lived by the principles that each day is a gift and that we never walk alone. His life is a shining example of how full one can be when you live with love, compassion, humour, inclusion, and community.” <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/C3wkUg9tOmj/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/C3wkUg9tOmj/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Kenneth Mitchell (@mr_kenneth_mitchell)</a> </div> </blockquote> Mitchell's journey with ALS, a progressive neurodegenerative disease, began in 2018 when he received the diagnosis. Despite the challenges it presented, he faced his condition with courage and resilience. By 2019, Mitchell had transitioned to using a wheelchair, and in 2020, he chose to share his health struggles publicly, shedding light on the realities of living with ALS. In an interview he gave during that time, Mitchell expressed the profound impact of his diagnosis on both himself and his wife, emphasising the strength they found in facing adversity together. He spoke of the initial shock and uncertainty surrounding his condition, highlighting the process of grieving and adjusting to a new reality marked by unknown challenges. For fans of Star Trek, Mitchell's portrayal of Klingon characters Kol, Kol-Sha, Tenavik, and Aurellio in Star Trek: Discovery resonated deeply, showcasing his talent and versatility as an actor. Additionally, his voice acting contributions to Star Trek: Lower Decks further solidified his place within the cherished franchise. The outpouring of tributes from the Star Trek community, as well as from his colleagues and fans worldwide, speaks volumes about Mitchell's impact both on and off the screen. A statement from StarTrek.com conveys condolences to Mitchell's family, friends, and loved ones, underscoring the profound loss felt by all who were touched by his work. Mitchell is survived by his wife Susan May Pratt and their two children, and has requested any gifts be directed towards ALS research or in support of his children. Images: Instagram

Running or yoga can help beat depression, research shows – even if exercise is the last thing you feel like

<a href="https://theconversation.com/profiles/michael-noetel-147460">Michael Noetel</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> At least <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2021.665019/full">one in ten people</a> have depression at some point in their lives, with some estimates <a href="https://www.sciencedirect.com/science/article/pii/S0749379720301793">closer to one in four</a>. It’s one of the worst things for someone’s wellbeing – worse than <a href="https://www.happinessresearchinstitute.com/_files/ugd/928487_4a99b6e23f014f85b38495b7ab1ac24b.pdf">debt, divorce or diabetes</a>. <a href="https://theconversation.com/why-are-so-many-australians-taking-antidepressants-221857">One in seven</a> Australians take antidepressants. Psychologists are in <a href="https://theconversation.com/we-cant-solve-australias-mental-health-emergency-if-we-dont-train-enough-psychologists-here-are-5-fixes-190135">high demand</a>. Still, only <a href="http://dx.doi.org/10.1371/journal.pmed.1003901">half</a> of people with depression in high-income countries get treatment. Our <a href="https://www.bmj.com/content/384/bmj-2023-075847">new research</a> shows that exercise should be considered alongside therapy and antidepressants. It can be just as impactful in treating depression as therapy, but it matters what type of exercise you do and how you do it. <h2>Walk, run, lift, or dance away depression</h2> We found 218 randomised trials on exercise for depression, with 14,170 participants. We analysed them using a method called a network meta-analysis. This allowed us to see how different types of exercise compared, instead of lumping all types together. We found walking, running, strength training, yoga and mixed aerobic exercise were about as effective as <a href="https://theconversation.com/explainer-what-is-cognitive-behaviour-therapy-37351">cognitive behaviour therapy</a> – one of the <a href="https://www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2018.00004/full">gold-standard treatments</a> for depression. The effects of dancing were also powerful. However, this came from analysing just five studies, mostly involving young women. Other exercise types had more evidence to back them. Walking, running, strength training, yoga and mixed aerobic exercise seemed more effective than antidepressant medication alone, and were about as effective as exercise alongside antidepressants. But of these exercises, people were most likely to stick with strength training and yoga. <iframe id="cZaWb" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/cZaWb/2/" width="100%" height="400px" frameborder="0"></iframe> Antidepressants certainly help <a href="https://www.thelancet.com/article/S0140-6736(17)32802-7/fulltext">some people</a>. And of course, anyone getting treatment for depression should talk to their doctor <a href="https://australia.cochrane.org/news/new-cochrane-review-explores-latest-evidence-approaches-stopping-long-term-antidepressants">before changing</a> what they are doing. Still, our evidence shows that if you have depression, you should get a psychologist and an exercise plan, whether or not you’re taking antidepressants. <h2>Join a program and go hard (with support)</h2> Before we analysed the data, we thought people with depression might need to “ease into it” with generic advice, <a href="https://www.who.int/initiatives/behealthy/physical-activity">such as</a> “some physical activity is better than doing none.” But we found it was far better to have a clear program that aimed to push you, at least a little. Programs with clear structure worked better, compared with those that gave people lots of freedom. Exercising by yourself might also make it hard to set the bar at the right level, given low self-esteem is a symptom of depression. We also found it didn’t matter how much people exercised, in terms of sessions or minutes a week. It also didn’t really matter how long the exercise program lasted. What mattered was the intensity of the exercise: the higher the intensity, the better the results. <h2>Yes, it’s hard to keep motivated</h2> We should exercise caution in interpreting the findings. Unlike drug trials, participants in exercise trials know which “treatment” they’ve been randomised to receive, so this may skew the results. Many people with depression have physical, psychological or social barriers to participating in formal exercise programs. And getting support to exercise isn’t free. We also still don’t know the best way to stay motivated to exercise, which can be even harder if you have depression. Our study tried to find out whether things like setting exercise goals helped, but we couldn’t get a clear result. Other reviews found it’s important to have a <a href="https://pubmed.ncbi.nlm.nih.gov/31923898/">clear action plan</a> (for example, putting exercise in your calendar) and to <a href="https://pubmed.ncbi.nlm.nih.gov/19916637/">track your progress</a> (for example, using an app or smartwatch). But predicting which of these interventions work is notoriously difficult. A <a href="https://www.nature.com/articles/s41586-021-04128-4">2021 mega-study</a> of more than 60,000 gym-goers <a href="https://www.nature.com/articles/s41586-021-04128-4/figures/1">found</a> experts struggled to predict which strategies might get people into the gym more often. Even making workouts fun didn’t seem to motivate people. However, listening to audiobooks while exercising helped a lot, which no experts predicted. Still, we can be confident that people benefit from personalised support and accountability. The support helps overcome the hurdles they’re sure to hit. The accountability keeps people going even when their brains are telling them to avoid it. So, when starting out, it seems wise to avoid going it alone. Instead: <ul> <li> join a fitness group or yoga studio </li> <li> get a trainer or an exercise physiologist </li> <li> ask a friend or family member to go for a walk with you. </li> </ul> Taking a few steps towards getting that support makes it more likely you’ll keep exercising. <h2>Let’s make this official</h2> Some countries see exercise as a backup plan for treating depression. For example, the American Psychological Association only <a href="https://www.apa.org/depression-guideline/">conditionally recommends</a> exercise as a “complementary and alternative treatment” when “psychotherapy or pharmacotherapy is either ineffective or unacceptable”. Based on our research, this recommendation is withholding a potent treatment from many people who need it. In contrast, The Royal Australian and New Zealand College of Psychiatrists <a href="https://www.ranzcp.org/getmedia/a4678cf4-91f5-4746-99d4-03dc7379ae51/mood-disorders-clinical-practice-guideline-2020.pdf">recommends</a> vigorous aerobic activity at least two to three times a week for all people with depression. Given how common depression is, and the number failing to receive care, other countries should follow suit and recommend exercise alongside front-line treatments for depression.

Run out of butter or eggs? Here’s the science behind substitute ingredients

<a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> It’s an all too common situation – you’re busy cooking or baking to a recipe when you open the cupboard and suddenly realise you are missing an ingredient. Unless you can immediately run to the shops, this can leave you scrambling for a substitute that can perform a similar function. Thankfully, such substitutes can be more successful than you’d expect. There are a few reasons why certain ingredient substitutions work so well. This is usually to do with the chemistry and the physical features having enough similarity to the original ingredient to still do the job appropriately. Let’s delve into some common ingredient substitutions and why they work – or need to be tweaked. <iframe id="IitfH" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/IitfH/1/" width="100%" height="400px" frameborder="0"></iframe> <h2>Oils versus butter</h2> Both butter and oils belong to a chemical class called <a href="https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Map%3A_Fundamentals_of_General_Organic_and_Biological_Chemistry_(McMurry_et_al.)/23%3A_Lipids/23.01%3A_Structure_and_Classification_of_Lipids">lipids</a>. It encompasses solid, semi-solid and liquid fats. In a baked product the “job” of these ingredients is to provide flavour and influence the structure and texture of the finished item. In cake batters, lipids contribute to creating an emulsion structure – this means combining two liquids that wouldn’t usually mix. In the baking process, this helps to create a light, fluffy crumb. One of the primary differences between butter and oil is that butter is only about 80% lipid (the rest being water), while <a href="https://www.nutritionadvance.com/types-of-cooking-fats-and-oils/">oil is almost 100% lipid</a>. Oil creates a softer crumb but is still a great fat to bake with. You can use a wide range of oils from different sources, such as olive oil, rice bran, avocado, peanut, coconut, macadamia and many more. Each of these may impart different flavours. Other “butters”, such as peanut and cashew butter, aren’t strictly butters but pastes. They impart different characteristics and can’t easily replace dairy butter, unless you also add extra oil. <h2>Aquafaba or flaxseed versus eggs</h2> Aquafaba is the liquid you drain from a can of legumes – such as chickpeas or lentils. It contains proteins, kind of how egg white also contains proteins. The proteins in egg white include albumins, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5912395/">aquafaba also contains albumins</a>. This is why it is possible to make meringue from egg whites, or from aquafaba if you’re after a vegan version. The proteins act as a foam stabiliser – they hold the light, airy texture in the product. The concentration of protein in egg white is a bit higher, so it doesn’t take long to create a stable foam. Aquafaba requires more whipping to create a meringue-like foam, but it will bake in a similar way. Another albumin-containing alternative for eggs is <a href="https://foodstruct.com/compare/seeds-flaxseed-vs-egg">flaxseed</a>. These seeds form a thick gel texture when mixed with a little water. The texture is similar to raw egg and can provide structure and emulsification in baked recipes that call for a small amount of egg white. <h2>Lemon plus dairy versus buttermilk</h2> Buttermilk is the liquid left over after churning butter – it can be made from sweet cream, cultured/sour cream or whey-based cream. Buttermilk mostly <a href="https://www.journalofdairyscience.org/article/S0022-0302(06)72115-4/fulltext">contains proteins and fats</a>. Cultured buttermilk has a somewhat tangy flavour. Slightly soured milk can be a good substitute as it contains similar components and isn’t too different from “real” buttermilk, chemically speaking. One way to achieve slightly soured milk is by adding some lemon juice or cream of tartar to milk. Buttermilk is used in pancakes and baked goods to give extra height or volume. This is because the acidic (sour) components of buttermilk interact with baking soda, producing a light and airy texture. Buttermilk can also influence flavour, imparting a slightly tangy taste to pancakes and baked goods. It can also be used in sauces and dressings if you’re looking for a lightly acidic touch. <h2>Honey versus sugar</h2> Honey is a <a href="https://resources.perkinelmer.com/lab-solutions/resources/docs/APP_Analysis-of-Sugars-in-Honey-012101_01.pdf">complex sugar-based syrup</a> that includes floral or botanical flavours and aromas. Honey can be used in cooking and baking, adding both flavour and texture (viscosity, softness) to a wide range of products. If you add honey instead of regular sugar in baked goods, keep in mind that honey imparts a softer, moister texture. This is because it contains more moisture and is a humectant (that is, it likes to hold on to water). It is also less crystalline than sugar, unless you leave it to crystallise. The intensity of sweetness can also be different – some people find honey is sweeter than its granular counterpart, so you will want to adjust your recipes accordingly. <h2>Gluten-free versus regular flour</h2> Sometimes you need to make substitutions to avoid allergens, such as gluten – the protein found in cereal grains such as wheat, rye, barley and others. Unfortunately, gluten is also the component that gives a nice, stretchy, squishy quality to bread. To build this characteristic in a gluten-free product, it’s necessary to have a mixture of ingredients that work together to mimic this texture. Common ingredients used are corn or rice flour, xanthan gum, which acts as a binder and moisture holder, and tapioca starch, which is a good water absorbent and can aid with binding the dough. <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/202036/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, Associate Professor (Food Science), <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Legendary broadway icon passes away

Iconic Broadway performer Chita Rivera has passed away at the age of 91. The dynamic dancer, singer and actress scored two Tony awards throughout her career, while blazing a trail for Latin American artists to shine on stage. On Wednesday morning, Rivera's daughter Lisa Mordente confirmed the news of her passing, sharing that her mother had died in New York after a brief illness. Rivera's representative Merle Frimark also shared a statement about her death, writing, "It is with immense personal sorrow that I announce the death of the beloved Broadway icon Chita Rivera. My dear friend of over 40 years was 91." "She is also survived by her siblings Julio, Armando and Lola del Rivero, (her older sister Carmen predeceased her), along with her many nieces, nephews and friends." "Her funeral will be private. A memorial service will be announced in due course." Rivera's breakout role came in 1957 as she starred as Anita in the original production of West Side Story, and she stayed performing in a multitude of roles until 2015. Chita starred in Broadway shows such as Bye Bye Birdie, Chicago, Merlin, Jerry's Girls, Nine, and many more. She also released two solo albums during her career, and was awarded the Presidential Medal of Freedom from former US president Barack Obama. Rivera won Tonys for The Rink in 1984 and Kiss of the Spider Woman in 1993, and when accepting a Tony Award for Lifetime Achievement in 2018, she said, "I wouldn't trade my life in the theatre for anything, because theatre is life." In 2015, she told The Associated Press, "I wouldn't know what to do if I wasn't moving or telling a story to you or singing a song." "That's the spirit of my life, and I'm really so lucky to be able to do what I love, even at this time in my life." Image credits: Getty Images
