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

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

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

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

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

<a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them. But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm? We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found. <h2>What are they?</h2> Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes. Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light. A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>. There’s often an added cost, which depends on the specific product. So, is the extra expense worth it? <h2>Blue light is all around us</h2> Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light. The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption>Screens emit blue light.

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

How to beat the retirement blues

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

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

One Sydney couple have taken their friends and family by surprise with their high-stakes gender reveal, where the father-to-be was apparently put under arrest by two police officers. Mina Ibrahim revealed their elaborate prank with a video posted to his TikTok account. Mina’s video begins with footage of the moment of his ‘arrest’, before it cuts to the TikToker at a later date, explaining that “that’s me being arrested at my baby’s gender reveal.” He goes on to share the full video, and a promise that the ending will answer any questions his viewers may have. In the clip, the parents-to-be can be seen talking to two uniformed NSW ‘police officers’, guests all around them, with Mina asking for onlookers to get their phones out. He then pushes one of the officers, telling them to leave, and both grab him before attempting to handcuff him, while his pregnant partner attempts to intervene. As family members rush to assist, one of the officers calls for everyone to calm down, then delivers news that takes them all by surprise - and delight - by telling them, “it’s a baby girl.” “So it was the cops who announced to everyone that I was having a baby girl,” present-day Mina informed his audience, before noting that there was a fake balloon inside to throw their guests off the surprise scent. <div class="mol-embed" style="margin: 0px 0px 8px; padding: 0px; min-height: 1px; letter-spacing: -0.16px; text-align: center; font-family: graphik, Arial, sans-serif; font-size: 16px; background-color: #ffffff;"> <blockquote id="v34606683345148116" class="tiktok-embed" style="margin: 18px auto; padding: 0px; min-height: 1px; letter-spacing: -0.01em; position: relative; width: 605px; box-sizing: border-box; line-height: 1.15; overflow: hidden; text-size-adjust: 100%; font-family: proxima-regular, PingFangSC, sans-serif; max-width: 605px; min-width: 325px;" cite="https://www.tiktok.com/@mina.ibs/video/7232964823296773383" data-video-id="7232964823296773383" data-embed-from="oembed"><iframe style="letter-spacing: -0.01em; border-width: initial; border-style: none; width: 605px; height: 735px; display: block; visibility: unset; max-height: 735px;" src="https://www.tiktok.com/embed/v2/7232964823296773383?lang=en-GB&referrer=https%3A%2F%2Fwww.dailymail.co.uk%2Fnews%2Farticle-12082153%2FGender-reveal-party-prank-sees-cops-arrest-father-be.html&embedFrom=oembed" name="__tt_embed__v34606683345148116" sandbox="allow-popups allow-popups-to-escape-sandbox allow-scripts allow-top-navigation allow-same-origin"></iframe></blockquote> </div> The prank attracted thousands of views online, with many flocking to his comments section to share their congratulations with the parents-to-be. Others, while thrilled for them and their happy news, were open about their concern, having fallen for the trick right along with the couple’s loved ones. “I fell for it and I was worried for your wife!!!,” one confessed. “I was freaking out hahahah you got me”. “I was worried too haha … you scared me,” another said. “Omygosh! I was ready to sue them coppas with you!” came one response, “but congratsss!

Aussie author of "Puberty Blues" dies at 64

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

Hill Street Blues star passes away

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

Warming oceans may force New Zealand’s sperm and blue whales to shift to cooler southern waters

The world’s oceans are absorbing more than <a href="https://www.un.org/en/climatechange/science/climate-issues/ocean-impacts" target="_blank" rel="noopener">90% of the excess heat and energy</a> generated by rising greenhouse gas emissions. But, as the oceans keep warming, rising sea temperatures generate unprecedented cascading effects that include the melting of polar ice, rising seas, marine heatwaves and ocean acidification. This in turn has profound impacts on marine biodiversity and the lives and livelihoods of coastal communities, especially in island nations such as New Zealand. In our latest <a href="https://www.sciencedirect.com/science/article/pii/S1470160X22007075?via%3Dihub" target="_blank" rel="noopener">research</a>, we focused on great whales – sperm and blue whales in particular. They are crucial for maintaining healthy marine ecosystems, but have limited options to respond to climate change: either adapt, die, or move to stay within optimal habitats. We used mathematical models to predict how they are likely to respond to warming seas by the end of the century. Our results show a clear southward shift for both species, mostly driven by rising temperatures at the sea surface. <h2>Computing the fate of whales</h2> Data on the local abundance of both whales species are <a href="https://www.int-res.com/abstracts/meps/v690/p201-217/" target="_blank" rel="noopener">deficient</a>, but modelling provides a powerful tool to predict how their range is likely to shift. We used a <a href="http://macroecointern.dk/pdf-reprints/AraujoNew2007.pdf" target="_blank" rel="noopener">combination of mathematical models</a> (known as correlative species distribution models) to predict the future range shifts of these whale species as a response to three future climate change scenarios of differing severity, as outlined by the Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch/" target="_blank" rel="noopener">IPCC</a>). We applied these models, using the whales’ present distributions, to build a set of environmental “rules” that dictate where each species can live. Using climate-dependent data such as sea-surface temperature and chlorophyll A (a measure of phytoplankton growth), as well as static data such as water depth and distance to shore, we applied these rules to forecast future habitat suitability. We chose a scenario of “<a href="https://www.nature.com/articles/d41586-020-00177-3" target="_blank" rel="noopener">modest</a>” response to cutting greenhouse gas emissions (the IPCC’s mitigation strategy RCP4.5), which is the most likely given the current policies, and a worst-case scenario (no policy to cut emissions, RCP8.5), assuming the reality will likely be somewhere between the two. Our projections suggest current habitats in the ocean around the North Island may become unsuitable if sea-surface temperatures continue to rise. These range shifts become even stronger with increasing severity of climate change. For sperm whales, which are currently abundant off Kaikōura where they support eco-tourism businesses, the predicted distribution changes are even more evident than for blue whales, depending on the climate change scenario. While our results do not predict an overall reduction in suitable habitat that would lead to local extinctions, the latitudinal range shifts are nevertheless bound to have important ecological consequences for New Zealand’s marine ecosystems and the people who depend on them. <h2>How whales maintain ecosystems</h2> Great whales are marine ecosystem engineers. They modify their habitats (or create new ones), to suit their needs. In fact, these activities create conditions that other species rely on to survive. They engineer their environment on several fronts. By feeding in one place and releasing their faeces in another, whales convey minerals and other nutrients such as nitrogen and iron from the deep water to the surface, as well as across regions. This process, known as a “<a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0013255" target="_blank" rel="noopener">whale pump</a>”, makes these nutrients available for phytoplankton and other organisms to grow. This is very important because phytoplankton contributes about <a href="https://education.nationalgeographic.org/resource/plankton-revealed" target="_blank" rel="noopener">half of all oxygen to the atmosphere</a> and also captures <a href="https://www.imf.org/Publications/fandd/issues/2019/12/natures-solution-to-climate-change-chami" target="_blank" rel="noopener">about 40% of all released carbon dioxide</a>. By helping the growth of phytoplankton, whales indirectly contribute to the <a href="https://theconversation.com/tiny-plankton-drive-processes-in-the-ocean-that-capture-twice-as-much-carbon-as-scientists-thought-136599" target="_blank" rel="noopener">natural ocean carbon sink</a>. On top of this, each great whale accumulates about <a href="https://www.arcticwwf.org/the-circle/stories/protecting-the-earth-by-protecting-whales/" target="_blank" rel="noopener">33 tonnes of carbon dioxide in their body</a>, which they take to the ocean floor when they die and their carcass sinks. <figure></figure> Ultimately, the impact of warming oceans on whale distribution is an additional stress factor on ecosystems already under pressure from wider threats, including acidification, pollution and over-exploitation. <h2>A way forward to help whales</h2> Sperm whales are the largest toothed whales (odontocetes) and deep-diving apex predators. They primarily feed on squid and fish that live near the bottom of the sea. Blue whales are baleen whales (mysticetes) and filter small organisms from the water. They feed at the surface on zooplankton, particularly dense krill schools along coastlines where cold water from the deep ocean rises toward the surface (so-called <a href="https://oceanservice.noaa.gov/facts/upwelling.html" target="_blank" rel="noopener">upwelling areas</a>). These differences in feeding habits lead to divergent responses to ocean warming. Blue whales show a more distinct southerly shift than sperm whales, particularly in the worst-case scenario, likely because they feed at the surface where ocean warming will be more exacerbated than in the deep sea. Both species have important foraging grounds off New Zealand which may be compromised in the future. Sperm whales are currently occurring regularly off Kaikōura, while blue whales forage in the South Taranaki Bight. Despite these ecological differences, our results show that some future suitable areas around the South Island and offshore islands are common to both species. These regions could be considered sanctuaries for both species to retreat to or expand their habitat in a warming world. This should warrant <a href="https://environment.govt.nz/assets/Publications/Files/Environmental-Report-Card-Marine-Areas-with-Legal-protection_0.pdf" target="_blank" rel="noopener">increased protection of these areas</a>.

How to roll away all your sore back blues

We all know that working a 9-5 and sitting all day leads to various health problems. For me personally, it manifests itself through chronic back pain and tight hip flexors. Fortunately, there's a way for me to soothe these aches and pains from home. I've been using <a href="https://www.therabody.com/anz/en-nz/wave-roller-anz.html" target="_blank" rel="noopener">Therabody's Wave Roller</a> for the past week, and my back pain has significantly reduced. The Wave Roller is a Bluetooth-enabled vibrating foam roller that proposes benefits like increasing blood flow, enhancing mobility, and releasing tension. You can connect the roller to a free Therabody App, where you can find personalised recovery routines targeting all parts of your body, along with instructions and how-tos. Here are some of my initial thoughts. <img src="https://oversixtydev.blob.core.windows.net/media/2022/03/03_RizWaveroller01.jpg" alt="Therabody Wave Roller in use" width="1280" height="720" /> My personal favourites are the mid back and upper back routines, which take up to 5 minutes to complete. Since most of the tension is in my upper body, which causes my lower back to overcompensate, I've decided to focus on these areas. The foam roller comes with a bag and charger and is reasonably lightweight, so you could easily carry it around. The foam itself is a high-density foam, and I like that you can customise the intensity and frequency of the vibrations. There are five customised vibration settings, with 5 being the highest and most intense. I could only handle up to the third setting or the medium-intensity. But, the higher the intensity, the more noise it produces, although I didn't mind it so much for the other benefits it provided. The routines are easy to follow, with pictures demonstrating each move and seamless transitions from one exercise to the next. I also liked that the intensity of the vibrations automatically changes according to what's best for that particular movement. I would have loved seeing a video demonstration before each routine, as I wasn't sure if I was doing some of the exercises quite correctly. I also found that the Wave Roller can be slippery to use in some movements, like when I tried it on my rotator cuffs. Despite this, the Wave Roller is a pleasure to use after a long day, when my muscles are the most tense. I find it a helpful tool in managing pain, soreness, and releasing tension. Although it is on the higher end of the price range compared to other foam rollers, I think it's worth the investment. The technology is advanced, and you can personalise the areas you want to work on using the step-by-step programs in their app. It also feels like you're getting a massage, but it's more personalised and customisable. If using the app seems intimidating or too complicated, you can use the Wave Roller by itself and adjust the intensity using the + and - buttons. <img src="https://oversixtydev.blob.core.windows.net/media/2022/03/02_RizWaveroller.jpg" alt="Therabody Wave Roller" width="1280" height="720" /> In summary, here are the pros and cons to consider if you're thinking of purchasing one for yourself. Pros: <ul> <li>Relieves soreness and muscle tension</li> <li>Variety of settings for the vibrations</li> <li>App integration </li> <li>Personalised programs that are quick and easy to follow</li> <li>3-hour battery life and it doesn’t take too long to charge</li> </ul> Cons: <ul> <li>The cost (RRP AU$249), but worth every penny! </li> <li>Medium to High setting intense and pretty noisy </li> <li>Depending on the exercise you do it can be quite slippery</li> <li>Video demonstrations before each exercise would be even better </li> </ul> The Wave Roller series is available via the <a href="https://www.therabody.com/anz/en-nz/home" target="_blank" rel="noopener">Therabody website</a>.

Blue-sky thinking: net-zero aviation is more than a flight of fantasy

As international air travel rebounds after COVID-19 restrictions, greenhouse gas emissions from aviation are expected to rise dramatically – and with it, scrutiny of the industry’s environmental credentials. Aviation emissions have almost <a href="https://www.newscientist.com/article/2253626-aviations-contribution-to-global-warming-has-doubled-since-2000/">doubled since 2000</a> and in 2018 reached <a href="https://ourworldindata.org/co2-emissions-from-aviation">one billion tonnes</a>. Climate Action Tracker rates the industry’s climate performance as <a href="https://climateactiontracker.org/sectors/aviation/">critically insufficient</a>. As the climate change threat rapidly worsens, can aviation make the transition to a low-carbon future – and perhaps even reach net-zero emissions? The significant technological and energy disruption on the horizon for the industry suggests such a future is possible. But significant challenges remain. Achieving a net-zero aviation sector will require a huge collaborative effort from industry and government – and consumers can also play their part. <iframe width="440" height="260" src="https://www.youtube.com/embed/nW6J989UBhA?wmode=transparent&start=0" frameborder="0" allowfullscreen=""></iframe> <h2>Build back better</h2> The aviation sector’s progress in cutting emissions has been disappointing to date. For example, in February last year, <a href="https://theconversation.com/major-airlines-say-theyre-acting-on-climate-change-our-research-reveals-how-little-theyve-achieved-127800">research</a> on the world’s largest 58 airlines found even the best-performing ones were not doing anywhere near enough to cut emissions. Most recently, at the COP26 climate change summit in Glasgow, the industry merely reasserted a commitment to a plan known as the <a href="https://www.icao.int/environmental-protection/CORSIA/Pages/default.aspx">Carbon Offsetting and Reduction Scheme for International Aviation</a>. The scheme relies on carbon offsetting, which essentially pays another actor to reduce emissions on its behalf at lowest cost, and doesn’t lead to absolute emissions reduction in aviation. The scheme also encourages alternative cleaner fuels, but the level of emissions reduction between fuels varies considerably. Governments have generally failed to provide strong leadership to help the aviation sector to reduce emissions. This in part is because pollution from international aviation is not counted in the emissions ledger of any country, leaving little incentive for governments to act. Aviation is also a complex policy space to navigate, involving multiple actors around the world. However, COVID-19 has significantly jolted the aviation and travel sector, presenting an opportunity to build back better – and differently. Griffith University recently held a <a href="https://www.griffith.edu.au/institute-tourism/our-research/rethinking-aviation/aviation-reimagined-2021?fbclid=IwAR3Hd8xLJkEWMaHae8sho1MiSfV6TzbPbf30vo2fbJ0CHMg-xdvywNCmZbU">webinar series</a> on decarbonising aviation, involving industry, academic and government experts. The sessions explored the most promising policy and practical developments for net-zero aviation, as well as the most significant hurdles. <img src="https://images.theconversation.com/files/437570/original/file-20211214-25-1rc1cnc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="passengers queue at airport" /> COVID-19 has significantly jolted the aviation sector. Steven Senne/AP <h2>Nations soaring ahead</h2> Some governments are leading the way in driving change in the aviation industry. For example, as a result of <a href="https://www.government.se/495f60/contentassets/883ae8e123bc4e42aa8d59296ebe0478/the-swedish-climate-policy-framework.pdf">government policy</a> to make Sweden climate-neutral by 2045, the Swedish aviation industry developed a <a href="https://fossilfrittsverige.se/en/roadmap/the-aviation-industry/#:%7E:text=The%20strategic%20objective%20for%202030,line%20with%20the%20Government%27s%20goals">roadmap</a> for fossil-free domestic flights by 2030, and for all flights originating from Sweden to be fossil-free by 2045. Achieving fossil-free flights requires replacing jet fuel with alternatives such as sustainable fuels or electric and hydrogen propulsion. The European Union plans to <a href="https://ec.europa.eu/commission/presscorner/detail/en/qanda_21_3662">end current tax exemptions</a> for jet fuel and introduce measures to <a href="https://www.eurocontrol.int/article/eus-fit-55-package-what-does-it-mean-aviation">accelerate</a> the uptake of sustainable fuels. The United Kingdom is finalising its strategy for <a href="https://www.gov.uk/government/consultations/achieving-net-zero-aviation-by-2050">net-zero aviation</a> by 2050 and a public body known as UK Research and Innovation is <a href="https://www.ukri.org/our-work/our-main-funds/industrial-strategy-challenge-fund/future-of-mobility/future-flight-challenge/">supporting</a> the development of new aviation technologies, including hybrid-electric regional aircraft. Australia lacks a strategic framework or emissions reduction targets to help transition the aviation industry. The <a href="https://www.infrastructure.gov.au/infrastructure-transport-vehicles/aviation/emerging-aviation-technologies/drones/eatp">Emerging Aviation Technology Program</a> seeks to reduce carbon emissions, among other goals. However, it appears to have a strong focus on freight-carrying drones and <a href="https://www.greenbiz.com/article/7-urban-air-mobility-companies-watch">urban air vehicles</a>, rather than fixed wing aircraft. <img src="https://images.theconversation.com/files/437569/original/file-20211214-13-lsswi6.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="plane taking off" /> Some governments are leading the way in driving change in the aviation industry. Zhao Xiaojun/AP <h2>Building tomorrow’s aircraft</h2> Low-emissions aircraft technology has developed substantially in the last five years. Advancements include electric and hybrid aircraft (powered by hydrogen or a battery) – such as that being developed by <a href="https://www.airbus.com/en/innovation/zero-emission/hydrogen/zeroe">Airbus</a>, <a href="https://www.rolls-royce.com/innovation/accel.aspx">Rolls Royce</a> and <a href="https://www.zeroavia.com/">Zero Avia</a> – as well as <a href="https://boeing.mediaroom.com/2021-07-14-Boeing-and-SkyNRG-Partner-to-Scale-Sustainable-Aviation-Fuels-Globally">sustainable aviation fuels</a>. Each of these technologies can reduce carbon emissions, but only battery and hydrogen electric options significantly reduce non-CO₂ climate impacts such as oxides of nitrogen (NOx), soot particles, oxidised sulphur species, and water vapour. For electric aircraft to be net-zero emissions, they must be powered by renewable energy sources. As well as being better for the planet, electric and hydrogen aircraft are likely to have <a href="https://www.zeroavia.com/">lower</a> energy and maintenance <a href="https://www.scientificamerican.com/article/electric-aviation-could-be-closer-than-you-think/">costs</a> than conventional aircraft. This decade, we expect a rapid emergence of electric and hybrid aircraft for short-haul, commuter, air taxi, helicopter and general flights. Increased use of sustainable aviation fuel is also likely. Although electric planes are flying, commercial operations are not expected until at least 2023 as the aircraft must undergo rigorous testing, safety and certification. <img src="https://images.theconversation.com/files/437571/original/file-20211214-23-1clsep1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="A solar powered aircraft prototype flies in mountainous terrain" /> Electric planes exist, but the route to commercialisation is long. Pictured: a solar powered aircraft prototype flies near the France-Italy border. Laurent Gillieron/EPA <h2>Overcoming turbulence</h2> Despite real efforts by some industry leaders and governments towards making aviation a net-zero industry, significant strategic and practical challenges remain. Conversion to the commercial mainstream is not happening quickly enough. To help decarbonise aviation in Australia, industry and government should develop a clear strategy for emissions reduction with interim targets for 2030 and 2040. This would keep the industry competitive and on track for net-zero emissions by 2050. Strategic attention and action is also needed to: <ul> <li> advance aircraft and fuel innovation and development </li> <li> update regulatory and certification processes for new types of aircraft </li> <li> enhance production and deployment of new aviation fuels and technologies </li> <li> reduce fuel demand through efficiencies in route and air traffic management </li> <li> create “greener” airport operations and infrastructure </li> <li> build capability with pilots and aerospace engineers. </li> </ul> The emissions created by flights and itineraries can <a href="https://theicct.org/sites/default/files/publications/variation-aviation-emissions-itinerary-jul2021-1.pdf">vary substantially</a>.

Blue Wiggle's stunning gesture for late veteran's family

Blue Wiggle Anthony Field has donated all his latest album's royalties to the family of a war veteran who passed away from cancer at age 30. Afghanistan veteran Brendan Nikolajew <a rel="noopener" href="https://www.oversixty.co.nz/health/caring/tragic-update-from-wife-of-terminally-ill-veteran" target="_blank">died</a> on July 29 this year after fighting testicular cancer on-and-off for the past three years. A few weeks prior, the Blue Wiggle <a rel="noopener" href="https://www.oversixty.co.nz/health/caring/veteran-with-terminal-cancer-speechless-after-blue-wiggle-s-kind-act" target="_blank">promised</a> to donate the royalties from the group’s latest album, Lullabies With Love, and has lived up to his word. After giving Mr Nikolajew all of his songwriting credits, the royalties will now go to his wife Leah, and their two young children. “I took my name off all the songwriting and put Brendan’s name instead, and gave him all the royalties and credits,” the musician <a rel="noopener" href="https://www.abc.net.au/news/2021-11-16/blue-wiggle-donates-aria-nominated-album-to-veterans-family/100620444" target="_blank">said</a>. He said Mr Nikolajew found the situation to be quite amusing. “We had a good laugh about this, because it’s nominated for an ARIA award, so if we win the ARIA that ARIA is going straight to Leah and the family, and we’ll get Brendan’s name engraved on it,” Field explained. “It would be fantastic — I mean, he’s got so many medals from his service and now he might end up with an ARIA too. “He was hoping to still be around for the ARIAs. He was going to take his daughter and son.” Field, a fellow Army veteran, became acquainted with Mr Nikolajew two and half years ago, and described him as “one in a million”. “He’s one of those people you are very lucky to meet in your life,” the 58-year-old said. “I learnt so much from that young man. He taught me how to live and boy, did he teach me how to die.” Just before Mr Nikolajew passed away, Field said the pair spoke about the loss of his niece. “Brendan lost his niece in the lead-up to his death and we had a good talk about it,” Field recalled. “I said to Brendan, ‘What’s going to happen when you pass over?’ “He said, ‘I’m going straight to my little niece’ — that’s the sort of man he was and I know he would be there now, looking after her.” Mr Nikolajew’s status as an ARIA award winner is yet to be determined, with the winners to be announced on November 24.

Dean Stockwell, star of Quantum Leap and Blue Velvet, dies at 85

Actor Dean Stockwell has passed away at the age of 85. According to a family spokesperson, Stockwell died of natural causes at home over the weekend, leaving behind a legacy that includes an early career as a child actor before quitting the industry at the age of 16, only to be drawn back into it in his 20s, where he would go on to star in films such as Quantum Leap, Blue Velvet, Dune, and Married to the Mob. His family said in a statement, "Dean spent a lifetime yo-yoing back and forth between fame and anonymity," his family said in a statement. Because of that, when he had a job, he was grateful. He never took the business for granted. He was a rebel, wildly talented and always a breath of fresh air." Stockwell, born to actor parents, grew up in North Hollywood, and started his career as a child actor during Hollywood’s Golden Age, making his Broadway debut in 1943 before being signed to a contract with MGM that saw him starring alongside Gregory Peck in The Valley of Decision and Gene Kelly and Frank Sinatra in Anchors Aweigh, both when he was just nine years old. In 1947, at the age of 11, he starred alongside Peck once more in Elia Kazan’s Gentlemen’s Agreement, playing Peck’s son. The 1950s saw him move back and forth between film and the emerging medium of television, before taking a break in 1951 and not acting again until 1956. The late 50s, 60s, and 70s saw Stockwell primarily appearing in countless television shows such as Alfred Hitchcock Presents, Dr Kildare, Bonanza, and Wagon Train, although there were a few memorable forays into film, including a role in Psych Out alongside Jack Nicholson and Bruce Dern. <blockquote class="twitter-tweet"> 🎶 In Dreams 🎶 The late Dean Stockwell in David Lynch’s BLUE VELVET (1986) 💙🎙 <a href="https://t.co/H3wZmmyvMC">pic.twitter.com/H3wZmmyvMC</a> — Criterion Collection (@Criterion) <a href="https://twitter.com/Criterion/status/1458130558584774656?ref_src=twsrc%5Etfw">November 9, 2021</a></blockquote> The 80s saw him star in some of his most memorable roles, such as Walt Henderson in Paris, Texas, and Ben in David Lynch’s 1986 film Blue Velvet, after previously working with Lynch in his 1984 adaptation of Dune. For his role as Tony “the Tiger” Russo in the 1988 film Married to the Mob, Stockwell was nominated for an Oscar. Another memorable role of Stockwell’s was that of Admiral ‘Al’ Calavicci in the sci-fi series Quantum Leap, which ran for five seasons between 1989 and 1993 and for which he was nominated for four Emmy Awards. Co-star Scott Bakula, who played Dr. Sam Beckett, said of Stockwell, “He became a dear friend and a mentor and we grew very close over the next five, very intense years… In spite of having a career that came and went several times during his seventy plus years in the business, he was always grateful and delighted to have the chance to keep working.” Image: Jim Russell/Toronto Star via Getty Images

Veteran with terminal cancer speechless after Blue Wiggle’s kind act

A Queensland army veteran has been left lost for words after finding out about how one of Australia’s biggest music stars plans to set his young family up for life. Wiggles member Anthony Field has pledged to donate the royalties from the group’s new album, Lullabies With Love, to Brendan Nikolajew’s wife and children. Nikolajew is in palliative care as he combats late-stage terminal cancer at home in Moreton Bay. “I never thought that I’d be receiving support and admiration from such a legend,” Nikolajew said of Field’s kind act on Instagram on Tuesday. “Anthony has given so much and it’s too humbling. “For this to be put into words is the hardest part … Just a massive thanks to everyone involved!” The 30-year-old war veteran, who served in Afghanistan, has been battling cancer for more than three years after a small lump was found on one of his testicles. After treatment of the lump, his cancer returned in November last year and was found in other areas of his body. Despite undergoing immediate chemotherapy treatment, he was recently given the terminal diagnosis and is making himself as comfortable as possible at home. His friend, Matthew James, spoke to 7NEWS in July, describing Nikolajew as “a positive guy”. “He’s the guy in the group who would try to pick you up if you were feeling down,” James said. “He’s definitely the most genuine bloke you could meet. “For the past three or so years he’s been really going through it, it’s never really sunk in. “He’s always been a positive guy. It’s kind of really starting to hit home. It’s a really rough time.” Field, the blue Wiggle who started the beloved children’s group in the 1990s, also served in the military. His gesture will be set to benefit Nikolajew’s wife Leah, their four-year-old daughter Georgie, and their two-year-old son Roman. More than $12000 has also been raised through a GoFundMe for the family. <blockquote 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);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CQ9SMwzhuxc/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="13"> <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> <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;" rel="noopener" href="https://www.instagram.com/p/CQ9SMwzhuxc/?utm_source=ig_embed&utm_campaign=loading" target="_blank">A post shared by Brendan Nikolajew (@brendans.cancer.fight)</a> </div> </blockquote> “These two and my wife, are the reasons I fight/fought so hard, so long and gave whatever it took,” Nikolajew said on Instagram recently. “I also lived my bloody life, which I’m proud of.” Image: Brendan Nikolajew / Instagram

The Ocean Decade: how the next ten years can chart a new course for the blue planet

When birdsong was filling the muted days of the first lockdown, marine scientists were noticing something similar in the world’s oceans. Container vessels, cruise ships and drilling platforms had fallen silent, and so the oceans grew quieter than at any other time in recent memory. Researchers are trying to understand how the lull affected ocean life, but there are already stories of whales seizing the chance to sing and dolphins venturing into coastal areas they’d avoided for decades. The year of the quiet ocean is over, and noise pollution is roaring back to pre-pandemic levels, drowning out the sounds that marine species depend on to communicate and make sense of their surroundings. Sadly, that’s just one problem among many. The UN has declared that the next ten years will be <a href="https://www.oceandecade.org/">the Decade of Ocean Science for Sustainable Development</a>, recognising the enormous challenges facing our blue planet. The Conversation has been keeping an eye on some of these as part of our <a href="https://theconversation.com/uk/topics/oceans-21-96784">Oceans 21 series</a>. Already, we’ve heard from experts about how chemical pollution in the ocean <a href="https://theconversation.com/why-ocean-pollution-is-a-clear-danger-to-human-health-152641">threatens human health</a>, how the ocean economy is dominated by <a href="https://theconversation.com/blue-economy-how-a-handful-of-companies-reap-most-of-the-benefits-in-multi-billion-ocean-industries-153165">a handful of mega-rich corporations</a> and why global warming is <a href="https://theconversation.com/the-ocean-is-becoming-more-stable-heres-why-that-might-not-be-a-good-thing-157911">making the ocean more stable</a> – with surprisingly worrying results.

Why you should turn your poop blue

A new trend has taken over social media, and this time it involves “blue poop”. But, this viral trend might actually be beneficial. The Blue Poop challenge involves eating food made with blue food colouring - usually two muffins - for breakfast to turn your poop blue. Why, you might ask? Because the viral challenge, started by nutrition research company ZOE, wants you to find out the state of your gut health by tracking how long it takes for food to travel through. “Poop is like a message from your gut, and it has a lot to say,” gut health nutritionist Amanda Sauceda, RDN, said in a <a href="https://joinzoe.com/bluepoop">video</a> about the challenge. How does it work? You can bake the muffins using a <a href="https://joinzoe.com/bluepoop/bake-blue-muffins">blue muffin recipe</a> on ZOE’s website, and you should eat two for breakfast and record the time. When you see the blue or green-tinted poop, write down the time again so that you can find out just how healthy your gut is via the <a href="https://bluepoop.joinzoe.com/why">ZOE website</a>. The recipe can also be altered to be gluten-free, but the company advises to use enough blue dye for the test to work. Why blue poop? Dr Sarah Berry, leader of nutrition sciences at King’s College London, worked with ZOE to publish a study asking participants to eat specially-tinted muffins to measure their transit time. “There are several scientific ways of measuring gut transit time, such as swallowing a special capsule or small wireless device,” Dr Berry said in a statement. “But these methods are complicated and invasive and can’t easily be done at home. Our data shows that transit time, tracked with blue dye, is an indicator of gut health, and is better than other non-invasive methods.” <blockquote class="twitter-tweet"> My blue muffins for the <a href="https://twitter.com/hashtag/bluepoopchallenge?src=hash&ref_src=twsrc%5Etfw">#bluepoopchallenge</a> <a href="https://t.co/PA1zvK3U4c">pic.twitter.com/PA1zvK3U4c</a> — Livia Văduva (@shamrockraver) <a href="https://twitter.com/shamrockraver/status/1394747513467514880?ref_src=twsrc%5Etfw">May 18, 2021</a></blockquote> Scientists found that transit time - the amount of time it takes for food to move through your gut - varied from under 12 hours to several days, with an average of around 29 hours. According to <a href="https://joinzoe.com/post/bluepoopchallenge">ZOE</a>, the tests showed that shorter transit times were generally linked with better health, having less abdominal fat, and healthier responses to food. Gut transit time is affected by diet, lifestyle, hydration, and the gut microbiome - the trillions of bugs living in the gut. Those who took more time to poop had more microbes that fed on protein and fewer fibre-loving bugs that produce short-chain fatty acids, helpful molecules that are linked to better gut health. “Interestingly, we also found that people with longer transit times were more likely to have a greater diversity of microbes in their gut, which is often associated with better gut health. This suggests that more microbiome diversity may not always be a sign of better health for people who don’t poop very often,” it said in a statement. “People with the very fastest transit times, suggesting they had diarrhoea, tended to have a less healthy gut microbiome,” the statement continued. Professor Tim Spector, epidemiologist at King’s College London and scientific founder of ZOE, said: “The Blue Poop Challenge is a simple way to find out what is going on in your gut. All you need are a couple of blue muffins and a spirit of curiosity to take that first step,” Image credit: ZOE / Instagram

"Blue and lifeless": Mum urges others to learn CPR after rescuing baby from ESKY

<div class="post_body_wrapper"> <div class="post_body"> <div class="body_text redactor-styles redactor-in"> Jacci Hutchinson has urged everyone she can to learn infant CPR after she rescued her best friends 8-month-old child from an esky. Jacci had been visiting her best friend Raewyn's house and all of their kids were playing together until Hutchinson realised that 8-month-old Bailey was missing. She realised there was an esky by the door and peered inside, only to find Bailey submerged in the water. "I thought it was a doll submerged in the water," Jacci tells <a rel="noopener" href="https://www.essentialbaby.com.au/baby/baby-health/mums-chilling-warning-after-saving-baby-from-drowning-in-an-esky-i-thought-it-was-a-doll-20210406-h1uyxm?utm_source=nine&utm_medium=referral&utm_campaign=homepage" target="_blank">Essential Baby</a>. "I went into shock. I don't think my brain could actually believe what I was seeing." "I put my hand in and touched his leg and felt his cold, wet skin," she recalls. "That's when I finally snapped. I realised... he was real and he was there in the water." After realising that Bailey was in the water, Jacci sprang into action. "I pulled Bailey out. I held him downwards to try and clear his airways. And I screamed for help," she continues. "I laid him on the carpet and looked up for a second and saw my friend calling an ambulance. Panic set into the house." "After that, I don't remember anything else except his little face. He was blue and lifeless." Luckily, Hutchinson was fully trained in CPR and immediately sprang into action to rescue Bailey. "I performed CPR for what felt like forever, but was only a short amount of time before his colouring started to improve," she recalls. "That's when I rolled him over and rubbed him on his back, and he arched his back and let out a cry. I rolled him back over and his eyes started to open, but he was very disoriented and drowsy." "So I monitored him pretty closely, wrapped him in a blanket and it was at that moment, the ambulance arrived." Bailey was rushed to hospital after paramedics arrived and returned home a short time later to his devastated but relieved mother. "She (Raewyn) just kept hugging me and saying, 'I don't know what I would have done if you weren't here," Jacci recalled. Bailey is now 14 years old, but the incident is something everyone else remembers, despite it happening in 2007. It also prompted Jacci to change career paths into infant aquatics and water safety. She has since completed her certificate IV in ambulance care and works as a swim instructor trying to raise awareness about CPR. "It is easy to learn, and having the confidence to respond and react in an emergency could make all the difference," Jacci explained. "I would encourage every single parent or caregiver to learn CPR. "Kids are drawn to water, and it only takes a very small amount. "I still get a chill every time I see an esky." </div> </div> </div>

Frightening photo shows why children should never wear blue while swimming

This terrifying photo shows how important it is for children to wear bright-coloured clothing while swimming as a child in a blue swimsuit is near impossible to spot. At first glance, the photo seems to show an empty swimming pool. But at closer look, a dark patch can be spotted which turns out to be a child wearing pale blue swimming shorts. <img style="width: 498.9539748953975px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7839750/screen-shot-2021-02-04-at-1-2.jpg" alt="" data-udi="umb://media/8a8d48619b6343f8abe58d77d162d3f1" /> The Australian Facebook group CPR Kids, which is run by registered nurses, posted the photo and issued a warning to parents, advising their child should be dressed in bright colours so they are visible in a pool. Nurse Sarah Hunstead also said it was “vital” to “actively supervise” kids and learn CPR. <img style="width: 498.9561586638831px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7839749/screen-shot-2021-02-04-at-1-1.jpg" alt="" data-udi="umb://media/d36cecb4938f4c98abfb207ea007db56" /> Hundreds of people have shared or commented on the image. “That is so scary! I couldn’t see the child at all,” one woman said. “Oh my god, how terrifying,” another said. A third wrote: “This makes me feel sick.” But many parents pointed out how difficult it is to find brightly coloured swimwear when shopping for children - especially boys. “Would be great if you could tell the manufacturers of swimwear!” one wrote. “Once kids get to 7yr it’s all blue/black/white.” Others who came across the photo promised to only dress their children in fluorescent colours. “All future swimwear is going to be hideous and fluoro,” one mum tagged her husband and wrote.

Blue Acceleration: our dash for ocean resources mirrors what we’ve already done to the land

Humans are leaving a heavy footprint on the Earth, but when did we become the main driver of change in the planet’s ecosystems? Many scientists point to the 1950s, when all kinds of socioeconomic trends began accelerating. Since then, <a href="https://www.weforum.org/agenda/2016/09/the-countries-with-the-biggest-populations-from-1950-to-2060/">the world population has tripled</a>. Fertiliser and water use expanded as <a href="https://theconversation.com/can-the-earth-feed-11-billion-people-four-reasons-to-fear-a-malthusian-future-43347">more food was grown than ever before</a>. The construction of motorways sped up to accommodate rising car ownership while international flights took off to satisfy a growing taste for tourism. The scale of human demands on Earth grew beyond historic proportions. This post-war period became known as the “<a href="https://theconversation.com/anthropocene-began-in-1965-according-to-signs-left-in-the-worlds-loneliest-tree-91993">Great Acceleration</a>”, and many believe it gave birth to the Anthropocene – the geological epoch during which human activity surpassed natural forces as the biggest influence on the functioning of Earth’s living systems. But researchers studying the ocean are currently feeling a sense of déjà vu. Over the past three decades, patterns seen on land 70 years ago have been occurring in the ocean. We’re living through a “<a href="https://www.cell.com/one-earth/fulltext/S2590-3322(19)30275-1">Blue Acceleration</a>”, and it will have significant consequences for life on the blue planet. Why is the Blue Acceleration happening now? As land-based resources have declined, hopes and expectations have increasingly turned to the ocean as a new engine of human development. Take deep sea mining. The international seabed and its mineral riches have excited commercial interest in recent years due to soaring commodity prices. According to the <a href="https://data.imf.org/commodityprices">International Monetary Fund</a>, the price of gold is up 454% since 2000, silver is up 317% and lead 493%. Around 1.4 million square kilometres of the seabed has been leased since 2001 by the International Seabed Authority for exploratory mining activities. In some industries, technological advances have driven these trends. Virtually all offshore windfarms were installed <a href="https://www.irena.org/Statistics">in the last 20 years</a>. The marine biotechnology sector scarcely existed at the end of the 20th century, and over <a href="https://advances.sciencemag.org/content/4/6/eaar5237">99% of genetic sequences from marine organisms</a> found in patents were registered since 2000. During the 1990s, as the Blue Acceleration got underway, <a href="https://www.infoplease.com/world/population-statistics/total-population-world-decade-1950-2050">the world population reached 6 billion</a>. Today there are around <a href="https://www.worldometers.info/world-population/">7.8 billion people</a>. Population growth in water-scarce areas like the Middle East, Australia and South Africa has caused a <a href="https://www.desaldata.com/">three-fold growth in volumes of desalinated seawater</a> generated since 2000. It has also meant a nearly <a href="https://data.worldbank.org/indicator/IS.SHP.GOOD.TU">four-fold increase</a> in the volume of goods transported around the world by shipping since 2000. Why does the Blue Acceleration matter? The ocean was once thought – even among prominent scientists – to be too vast to be changed by human activity. That view has been replaced by the uncomfortable recognition that not only can humans change the ocean, but also that the current trajectory of human demands on the ocean simply isn’t sustainable. Consider the coast of Norway. The region is home to a multi-million dollar ocean-based oil and gas industry, aquaculture, popular cruises, busy shipping routes and fisheries. All of these interests are vying for the same ocean space, and their demands are growing. A five-fold increase in the number of salmon grown by aquaculture is expected by 2050, while the region’s tourism industry is predicted to welcome a five-fold increase in visitors by 2030. Meanwhile, <a href="https://www.offshorewind.biz/2019/06/19/norway-ponders-3-5gw-offshore-wind-move/">vast offshore wind farms</a> have been proposed off the southern tip of Norway. The ocean is vast, but it’s not limitless. This saturation of ocean space is not unique to Norway, and a densely populated ocean space runs the risk of conflict across industries. Escapee salmon from aquaculture have <a href="https://www.regjeringen.no/en/topics/food-fisheries-and-agriculture/fishing-and-aquaculture/1/farmed-salmon/fish-healthsalmon-lice/id607091/">spread sea lice in wild populations</a>, creating tensions with Norwegian fisheries. An industrial accident in the oil and gas industry could cause significant damage to local seafood and tourism as well as the seafood export market. More fundamentally, the burden on ocean ecosystems is growing, and we simply don’t know as much about these ecosystems as we would like. An ecologist once quipped that fisheries management is the same as forestry management. Instead of trees you’re counting fish, except you can’t see the fish, and they move. Exploitation of the ocean has tended to precede exploration. One iconic example is <a href="https://theconversation.com/sea-pangolin-the-first-ever-species-endangered-by-potential-deep-sea-mining-120624">the scaly-foot snail</a>. This deep sea mollusc was discovered in 1999 and was on the IUCN Red List of endangered species by 2019. Why? As far as scientists can tell, the species is only found in three hydrothermal vent systems more than 2,400 metres below the Indian Ocean, covering less than 0.02 square kilometres. Today, two of the three vent systems fall within exploratory mining leases. What next? Billionaires dreaming of space colonies can dream a little closer to home. Even as the Blue Acceleration consumes more of the ocean’s resources, this vast area is every bit as mysterious as outer space. The surfaces of Mars and the Moon have been mapped in <a href="https://www.ncei.noaa.gov/news/mapping-our-planet-one-ocean-time">higher resolution than the seafloor</a>. Life in the ocean has existed for two billion years longer than on land and an estimated <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1001127">91% of marine species have not been described by science</a>. Their genetic adaptations could help scientists develop the <a href="https://theconversation.com/nature-is-a-rich-source-of-medicine-if-we-can-protect-it-107471">antibiotics and medicines of tomorrow</a>, but they may disappear long before that’s possible. The timing is right for guiding the Blue Acceleration towards more sustainable and equitable trajectories. The <a href="https://en.unesco.org/ocean-decade">UN Decade of Ocean Science for Sustainable Development</a> is about to begin, a new <a href="https://www.un.org/bbnj/">international treaty on ocean biodiversity</a> is in its final stages of negotiation, and in June 2020, governments, businesses, academics and civil society will assemble for the <a href="https://oceanconference.un.org/">UN Ocean Conference</a> in Lisbon. Yet many simple questions remain. Who is driving the Blue Acceleration? Who is benefiting from it? And who is being left out or forgotten? These are all urgent questions, but perhaps the most important and hardest to answer of all is how to create connections and engagement across all these groups. Otherwise, the drivers of the Blue Acceleration will be like the fish in the ecologist’s analogy: constantly moving, invisible and impossible to manage – before it is too late.

Brooke Shields is heading into 2020 with a homage to one of her iconic 1980 roles. Two days before the year ended, the 54-year-old actress and model took to Instagram to showcase her toned body. In the picture, Shields could be seen standing on the beach wearing navy blue bikini. <blockquote 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);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/B6rOA7tADF5/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="12"> <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> <a style="color: #000; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none; word-wrap: break-word;" rel="noopener" href="https://www.instagram.com/p/B6rOA7tADF5/?utm_source=ig_embed&utm_campaign=loading" target="_blank">another blue lagoon 💙</a> <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 post shared by <a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px;" rel="noopener" href="https://www.instagram.com/brookeshields/?utm_source=ig_embed&utm_campaign=loading" target="_blank"> Brooke Shields</a> (@brookeshields) on Dec 29, 2019 at 3:46pm PST </div> </blockquote> “Another blue lagoon,” she wrote on the caption, referring to the 1980 film The Blue Lagoon where she played the lead role of Emmeline Lestrange.
