Could my glasses be making my eyesight worse?

<p><em><a href="https://theconversation.com/profiles/james-armitage-399647">James Armitage</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/nick-hockley-1517162">Nick Hockley</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>So, you got your eyesight tested and found out you need your first pair of glasses. Or you found out you need a stronger pair than the ones you have. You put them on and everything looks crystal clear. But after a few weeks things look blurrier without them than they did before your eye test. What’s going on?</p> <p>Some people start to wear spectacles for the first time and perceive their vision is “bad” when they take their glasses off. They incorrectly interpret this as the glasses making their vision worse. Fear of this might make them <a href="https://www.bbc.com/future/article/20140513-do-glasses-weaken-your-eyesight#:%7E:text=A%20study%20from,they%20are%20right%3F">less likely to wear their glasses</a>.</p> <p>But what they are noticing is how much better the world appears through the glasses. They become <a href="https://www.tandfonline.com/doi/full/10.1080/2576117X.2022.2033588">less tolerant</a> of a blurry world when they remove them.</p> <p>Here are some other things you might notice about eyesight and wearing glasses.</p> <h2>Lazy eyes?</h2> <p>Some people sense an increasing reliance on glasses and wonder if their eyes have become “lazy”.</p> <p>Our eyes work in much the same way as an auto-focus camera. A flexible lens inside each eye is controlled by muscles that let us <a href="https://www.aao.org/museum-eye-openers/how-does-eye-focus">focus on objects</a> in the distance (such as a footy scoreboard) by relaxing the muscle to flatten the lens. When the muscle contracts it makes the lens steeper and more powerful to see things that are much closer to us (such as a text message).</p> <p>From the age of about 40, the lens in our eye <a href="https://theconversation.com/why-we-lose-our-hearing-and-vision-as-we-age-67930">progressively hardens</a> and loses its ability to change shape. Gradually, we lose our capacity to focus on near objects. This is called “<a href="https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/presbyopia">presbyopia</a>” and at the moment there are no treatments for this lens hardening.</p> <p>Optometrists correct this with prescription glasses that take the load of your natural lens. The lenses allow you to see those up-close images clearly by providing extra refractive power.</p> <p>Once we are used to seeing clearly, our tolerance for blurry vision will be lower and we will reach for the glasses to see well again.</p> <h2>The wrong glasses?</h2> <p>Wearing old glasses, the wrong prescription (or even someone else’s glasses) won’t allow you to see as well as possible for day-to-day tasks. It could also cause <a href="https://headaches.org/readers-mail-glasses-causing-headache/">eyestrain and headaches</a>.</p> <p>Incorrectly prescribed or dispensed prescription glasses can lead to vision impairment in children <a href="https://iovs.arvojournals.org/article.aspx?articleid=2126392">as their visual system is still in development</a>.</p> <p>But it is more common for kids to develop long-term vision problems as a result of <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">not wearing glasses when they need them</a>.</p> <p>By the time children are about 10–12 years of age, wearing incorrect spectacles is less likely to cause their eyes to become lazy or damage vision in the long term, but it is likely to result in <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">blurry or uncomfortable vision</a> during daily wear.</p> <p><a href="https://goodvisionforlife.com.au/">Registered optometrists in Australia</a> are trained to assess refractive error (whether the eye focuses light into the retina) as well as the different aspects of ocular function (including how the eyes work together, change focus, move around to see objects). All of these help us see clearly and comfortably.</p> <h2>What about dirty glasses?</h2> <p>Dirty or scratched glasses can give you the impression your vision is worse than it actually is. Just like a window, the dirtier your glasses are, the more difficult it is to see clearly through them. <a href="https://www.optometry.org.au/wp-content/uploads/GVFL/Brochure_PDFs/Care-for-Glasses-2018-A4-single-page-final.pdf">Cleaning glasses regularly</a> with a microfibre lens cloth will help.</p> <p>While dirty glasses are not commonly associated with eye infections, some research suggests dirty glasses can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">harbour bacteria</a> with the remote but theoretical <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6628431/#:%7E:text=59%2C60%5D.-,S.,39%2C40%2C41%5D.">potential to cause eye infection</a>.</p> <p>To ensure best possible vision, people who wear prescription glasses every day should clean their lenses at least every morning and twice a day where required. Cleaning frames with alcohol wipes can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">reduce bacterial contamination by 96%</a> – but care should be taken as alcohol can damage some frames, depending on what they are made of.</p> <h2>When should I get my eyes checked?</h2> <p><a href="https://goodvisionforlife.com.au/faqs/">Regular eye exams</a>, starting just before school age, are important for ocular health. Most prescriptions for corrective glasses <a href="https://www.ahpra.gov.au/documents/default.aspx?record=WD16%2F20156&amp;dbid=AP&amp;chksum=676U2aH1QM4XJ6ICVAVaKg%3D%3D">expire within two years</a> and contact lens prescriptions often expire after a year. So you’ll need an eye check for a new pair every year or so.</p> <p>Kids with ocular conditions such as progressive myopia (short-sightedness), strabismus (poor eye alignment), or amblyopia (reduced vision in one eye) will need checks at least every year, but likely more often. Likewise, people over 65 or who have known eye conditions, such as <a href="https://goodvisionforlife.com.au/vision-problems/glaucoma/">glaucoma</a>, will be recommended more frequent checks.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6706420/">online prescription estimator</a> is no substitute for a full eye examination. If you have a valid prescription then you can order glasses online, but you miss out on the ability to check the fit of the frame or to have them adjusted properly. This is particularly important for multifocal lenses where even a millimetre or two of misalignment can cause uncomfortable or blurry vision.</p> <p>Conditions such as <a href="https://www.cdc.gov/diabetes/managing/diabetes-vision-loss.html#:%7E:text=Diabetic%20retinopathy%20is%20caused%20when,vision%20or%20stopping%20blood%20flow.">diabetes</a> or <a href="https://www.ncbi.nlm.nih.gov/books/NBK525980/">high blood pressure</a>, can affect the eyes so regular eye checks can also help flag broader health issues. The vast majority of eye conditions can be treated if caught early, highlighting the importance of regular preventative care.<!-- Below is The Conversation's page counter tag.

Two more infant deaths at Queensland hospital spark coroner's investigation

<p>In the wake of a recent healthcare scandal involving infant fatalities at a Queensland hospital, the state coroner is now delving into two more heartbreaking cases at the same facility, as <a href="https://www.abc.net.au/news/2024-03-12/coroner-investigating-more-baby-deaths-at-mackay-base-hospital/103573248" target="_blank" rel="noopener">reported by the ABC</a>. This development has reignited concerns about the safety and quality of care provided to expectant mothers and newborns at Mackay Base Hospital.</p> <p>The stories of Chloe Stanley and Jenna McGregor echo a disturbing pattern of maternal distress, dismissal of concerns and tragic outcomes. Stanley's baby girl, Everlee, tragically passed away in her arms just seven days after birth in May 2023, while McGregor lost her son, Hugo, five days after his birth, two months prior. Both infants succumbed to hypoxic-ischaemic encephalopathy, a condition stemming from oxygen or blood flow deprivation during birth.</p> <p>Stanley's harrowing experience sheds light on a systemic issue of young mothers feeling marginalised and ignored by healthcare professionals. At just 19 years old, Stanley expressed her belief that she was being "judged" for her ago, leading to dismissal of her concerns about her baby's well-being, ultimately resulting in devastating consequences. McGregor's ordeal parallels Stanley's, underscoring a troubling lack of responsiveness to maternal distress and the urgent need for systemic reforms.</p> <p>These recent tragedies evoke haunting memories of <a href="https://www.abc.net.au/news/2022-09-30/mackay-hospital-health-service-babies-obstetrics-review/101411172" target="_blank" rel="noopener">a similar case a decade ago</a>, involving the loss of Jessica Beazley's newborn son, Nathan. Like Stanley and McGregor, <a href="https://www.abc.net.au/news/2022-09-30/mackay-base-hospital-obstetrics-harming-mother-and-baby/101485862" target="_blank" rel="noopener">Beazley's concerns </a>appear to have  been disregarded, leading to irreversible harm. An investigation into Mackay Base Hospital's obstetrics and gynaecology service in 2022 revealed a disturbing pattern of inadequate care contributing to infant deaths and maternal suffering, prompting calls for comprehensive reforms.</p> <p>The review uncovered 122 recommendations aimed at improving communication, culture and empathy within the hospital's maternity care system. However, despite assurances of progress, Stanley and McGregor's experiences suggest that critical reforms have yet to be fully implemented, leaving expectant mothers vulnerable to similar tragedies.</p> <p>The Root Cause Analysis conducted by the Mackay Hospital and Health Service (MHHS) following McGregor's loss identified several systemic deficiencies, including delays in care escalation, poor collaboration and communication breakdowns. These findings underscore the urgent need for sustained efforts to address systemic failures and ensure the safety of expectant mothers and their babies.</p> <p>Stanley's and McGregor's accounts of feeling dismissed and unheard by healthcare providers highlight a pervasive culture of neglect and complacency that must be addressed. </p> <p>In response to these tragedies, health authorities have pledged to bolster obstetric care and enhance staff training and empathy initiatives. </p> <p>As the Queensland coroner investigates these heartbreaking cases, it is imperative that lessons are learned, and systemic reforms are swiftly implemented to prevent further loss of innocent lives.</p> <p>Expectant mothers like Chloe Stanley and Jenna McGregor deserve nothing less than the highest standard of care and compassion throughout their pregnancy and childbirth journey.</p> <p><em>Images: Mackay Base Hospital \ Getty Images file photo</em> </p>

Viral videos show influencers tossing back shots of cult olive oil brands, and proclaiming a wide range of health benefits from improving digestion to clearing up acne.</p> <p>Celebrity and influencers are sold on liquid gold but what about the rest of us? Can drinking olive oil really work on miracles for our health?</p> <h2>The benefits of olive oil</h2> <p>There’s no doubt that olive oil is full of good stuff. It’s high in polyphenols and antioxidants, which have protective qualities for the body’s tissues. It’s also a rich source of essential fatty acids, including oleic acid, which is known for <a href="https://foodrevolution.org/blog/olives-and-olive-oil-benefits/#:%7E:text=Compared%20with%20olives%2C%20olive%20oil,in%20polyphenols%20and%20antioxidants%2C%20however">lowering cholesterol</a> so reducing the chances of heart disease.</p> <p>Research has found that the inclusion of olive oil in the diet shows encouraging effects in a variety of <a href="https://doi.org/10.3390%2Fnu11092039">inflammatory and medical diseases</a> and can <a href="https://doi.org/10.3389%2Ffnut.2022.980429">support weight management</a> if used correctly.</p> <p>Replacing butter, margarine, mayonnaise and dairy fat with olive oil has been linked to a <a href="https://doi.org/10.1016%2Fj.jacc.2021.10.041">lower risk of mortality</a>. There’s also evidence to suggest that the protective compounds in olive oil may help <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0261649">guard against cancer</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10376491/">dementia</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/29141573/">support the liver</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7916323/">and kidneys</a>.</p> <p>But none of this is new information to health professionals. The health benefits of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7466243/">extra virgin olive oil</a> are <a href="https://doi.org/10.3390%2Fnu11092039">well researched</a> and nutritionists have promoted olive oil as a swap for saturated cooking fat for years.</p> <p>After all, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7536728/">Mediterranean diet</a> has been touted as one of the healthiest diets in the world for decades. The diet itself can vary from region to region, but <a href="https://doi.org/10.3390%2Fnu15092127">virgin olive oil</a> is a <a href="https://doi.org/10.3390%2Fnu11092039">consistent element</a>. It’s used as the <a href="https://www.themediterraneandish.com/cooking-with-olive-oil/">main source of cooking fat</a> and included in everything from salad dressings to bread.</p> <figure><iframe src="https://www.youtube.com/embed/krFcE5IPT7g?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Can fat be healthy? Yes and no</h2> <p>Fats are crucial for a balanced diet, aiding in the absorption of fat-soluble vitamins A,D,E,K and enhancing the nutritional value of meals.</p> <p>However, fat of any kind is also dense in calories and excessive consumption <a href="https://doi.org/10.1159/000336848">can lead to weight gain</a>. According to the <a href="https://www.who.int/news/item/17-07-2023-who-updates-guidelines-on-fats-and-carbohydrates">World Health Organization</a>, to prevent unhealthy weight gain, adults should limit their intake of fat to 30% of total energy intake with no more than 10% coming from saturated fats.</p> <p>Two tablespoons of olive oil – the standard amount in the shots taken by celebrities and social media influencers – contain 28g of fat (238 calories) and 3.8g of saturated fat equating to <a href="https://fdc.nal.usda.gov/fdc-app.html#/food-details/171413/nutrients">19% of the recommended daily intake</a>.</p> <p>That daily shot of extra virgin, then, might not be the best idea. Adding small amounts of olive oil to meals throughout the day is a more balanced – and appetising – approach to incorporating healthy fats into your diet.</p> <p>But what about Kourtney Kardashian’s <a href="https://poosh.com/why-kourtney-kardashian-drinks-tablespoon-evoo/#:%7E:text=First%20things%20first%2C%20it's%20recommended,a.m.%20(every%20other%20day).">claim that</a>: “It’s recommended to consume extra virgin olive oil in the morning on an empty stomach so the oil can coat your system and neutralize your stomach walls for optimal benefits?”</p> <p><a href="https://www.oliveoiltimes.com/briefs/consuming-olive-oil-on-an-empty-stomach-health-benefits/91503">Some brands</a> have also echoed the idea that consuming olive oil on an empty stomach offers unique health benefits. But no. There’s no scientific evidence to suggest this is true.</p> <p>For a healthy but more satisfying snack, Kourtney might try including a handful of olives into her daily diet. Olives offer the same rich array of nutrients, including vitamins E, A and K, alongside essential minerals such as iron, calcium, magnesium, potassium and amino acids.</p> <p>Unlike olive oil, olives have the added benefit of a high fibre content. The combination of fat and fibre enhances feelings of satiety, making olives a nutritious addition to the diet.<!-- Below is The Conversation's page counter tag.

We looked at 700 plant-based foods to see how healthy they really are. Here’s what we found

<p><em><a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>If you’re thinking about buying plant-based foods, a trip to the supermarket can leave you bewildered.</p> <p>There are plant-based burgers, sausages and mince. The fridges are loaded with non-dairy milk, cheese and yoghurt. Then there are the tins of beans and packets of tofu.</p> <p>But how much is actually healthy?</p> <p>Our nutritional audit of more than 700 plant-based foods for sale in Australian supermarkets has just been <a href="https://www.sciencedirect.com/science/article/pii/S0889157524000516">published</a>. We found some products are so high in salt or saturated fat, we’d struggle to call them “healthy”.</p> <h2>We took (several) trips to the supermarket</h2> <p>In 2022, we visited two of each of four major supermarket retailers across Melbourne to collect information on the available range of plant-based alternatives to meat and dairy products.</p> <p>We took pictures of the products and their nutrition labels.</p> <p>We then analysed the nutrition information on the packaging of more than 700 of these products. This included 236 meat substitutes, 169 legumes and pulses, 50 baked beans, 157 dairy milk substitutes, 52 cheese substitutes and 40 non-dairy yoghurts.</p> <h2>Plant-based meats were surprisingly salty</h2> <p>We found a wide range of plant-based meats for sale. So, it’s not surprising we found large variations in their nutrition content.</p> <p>Sodium, found in added salt and which contributes to <a href="https://www.heartfoundation.org.au/bundles/healthy-living-and-eating/salt-and-heart-health">high blood pressure</a>, was our greatest concern.</p> <p>The sodium content varied from 1 milligram per 100 grams in products such as tofu, to 2,000mg per 100g in items such as plant-based mince products.</p> <p>This means we could eat our entire <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/salt">daily recommended sodium intake</a> in just one bowl of plant-based mince.</p> <p>An <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">audit</a> of 66 plant-based meat products in Australian supermarkets conducted in 2014 found sodium ranged from 316mg in legume-based products to 640mg in tofu products, per 100g. In a <a href="https://www.mdpi.com/2072-6643/11/11/2603">2019 audit</a> of 137 products, the range was up to 1,200mg per 100g.</p> <p>In other words, the results of our audit seems to show a consistent trend of plant-based meats <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">getting saltier</a>.</p> <h2>What about plant-based milks?</h2> <p>Some 70% of the plant-based milks we audited were fortified with calcium, a nutrient important for <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/calcium">bone health</a>.</p> <p>This is good news as a <a href="https://www.mdpi.com/2072-6643/12/5/1254">2019-2020 audit</a> of 115 plant-based milks from Melbourne and Sydney found only 43% of plant-based milks were fortified with calcium.</p> <p>Of the fortified milks in our audit, almost three-quarters (73%) contained the <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/milk-yoghurt-cheese-andor-their-alternatives-mostly-reduced-fat">recommended amount of calcium</a> – at least 100mg per 100mL.</p> <p>We also looked at the saturated fat content of plant-based milks.</p> <p>Coconut-based milks had on average up to six times higher saturated fat content than almond, oat or soy milks.</p> <p><a href="https://www.mdpi.com/2072-6643/12/5/1254">Previous audits</a> also found coconut-based milks were much higher in saturated fat than all other categories of milks.</p> <h2>A first look at cheese and yoghurt alternatives</h2> <p>Our audit is the first study to identify the range of cheese and yoghurt alternatives available in Australian supermarkets.</p> <p>Calcium was only labelled on a third of plant-based yoghurts, and only 20% of supermarket options met the recommended 100mg of calcium per 100g.</p> <p>For plant-based cheeses, most (92%) were not fortified with calcium. Their sodium content varied from 390mg to 1,400mg per 100g, and saturated fat ranged from 0g to 28g per 100g.</p> <h2>So, what should we consider when shopping?</h2> <p>As a general principle, try to choose whole plant foods, such as unprocessed legumes, beans or tofu. These foods are packed with vitamins and minerals. They’re also high in dietary fibre, which is good for your gut health and keeps you fuller for longer.</p> <p>If opting for a processed plant-based food, here are five tips for choosing a healthier option.</p> <p><strong>1. Watch the sodium</strong></p> <p>Plant-based meat alternatives can be high in sodium, so look for products that have <a href="https://www.eatforhealth.gov.au/eating-well/how-understand-food-labels/food-labels-what-look">around</a> 150-250mg sodium per 100g.</p> <p><strong>2. Pick canned beans and legumes</strong></p> <p>Canned chickpeas, lentils and beans can be healthy and low-cost <a href="https://www.heartfoundation.org.au/getmedia/71522940-decf-436a-ba44-cd890dc18036/Meat-Free-Recipe-Booklet.pdf">additions to many meals</a>. Where you can, choose canned varieties with no added salt, especially when buying baked beans.</p> <p><strong>3. Add herbs and spices to your tofu</strong></p> <p>Tofu can be a great alternative to meat. Check the label and pick the option with the highest calcium content. We found flavoured tofu was higher in salt and sugar content than minimally processed tofu. So it’s best to pick an unflavoured option and add your own flavours with spices and herbs.</p> <p><strong>4. Check the calcium</strong></p> <p>When choosing a non-dairy alternative to milk, such as those made from soy, oat, or rice, check it is fortified with calcium. A good alternative to traditional dairy will have at least 100mg of calcium per 100g.</p> <p><strong>5. Watch for saturated fat</strong></p> <p>If looking for a lower saturated fat option, almond, soy, rice and oat varieties of milk and yoghurt alternatives have much lower saturated fat content than coconut options. Pick those with less than 3g per 100g.<!-- Below is The Conversation's page counter tag.

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

<p><em><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></em></p> <p>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.</p> <p>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?</p> <p>We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found.</p> <h2>What are they?</h2> <p>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.</p> <p>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.</p> <p>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>.</p> <p>There’s often an added cost, which depends on the specific product. So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>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.</p> <p>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.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;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&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption><span class="caption">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.</p> <p>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.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>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.</p> <h2>Do they help you sleep?</h2> <p>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.</p> <p>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.</p> <h2>Do they boost your eye health?</h2> <p>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).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>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.</p> <p>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.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>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.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>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.</p> <h2>In a nutshell</h2> <p>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.</p> <p>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.</p> <p>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.<!-- Below is The Conversation's page counter tag.

Priscilla Presley's reaction to movie based on her life

<p>Priscilla Presley has shared how "emotional" she became after watching the new movie based on her life with her late rock star husband. </p> <p>The 78-year-old attended the premiere of the new film <em>Priscilla</em>, which was based on her 1985 memoir <em>Elvis &amp; Me. </em></p> <p>Priscilla took to the red carpet at the Venice International Film Festival on September 4th alongside director Sofia Coppola and the cast.</p> <p>"It was very difficult to sit and watch a film about you, about your life, about your love," she explained at a media call following the premiere screening.</p> <p>"Sofia did an amazing job. She did her homework, we spoke a couple of times and I really put everything out for her that I could," she added.</p> <p>Priscilla went on to explain why she thought her love story was so intriguing to a public audience, as she spoke about the early days of her relationship with the late rock star. </p> <p>"It was very difficult for my parents to understand that Elvis would be so interested in me and why, and I really do think [it was] because I was more of a listener," she said.</p> <p>"Elvis would pour his heart out to me in every way in Germany: his fears, his hopes, the loss of his mother which he never, ever got over. And I was the person who really, really sat there to listen and to comfort him. That was really our connection."</p> <p>She continued, "Even though I was 14, I was actually a little bit older in life, not in numbers. That was the attraction. People think, 'Oh, it was sex.' No, it wasn't. I never had sex with him. He was very kind, very soft, very loving, but he also respected the fact I was only 14 years old."</p> <p><em>Euphoria</em> star and Aussie actor Jacob Elordi plays Elvis in the new film, with Cailee Spaeny in the title role of Priscilla, which traces Priscilla's early years and relationship with the music icon.</p> <p>Elvis Presley estate officials reportedly slammed the movie, with <em><a title="TMZ" href="https://www.tmz.com/2023/06/22/elvis-presley-estate-officials-slam-priscilla-movie/" target="_blank" rel="noopener">TMZ</a></em> claiming unnamed officials were displeased with news of the production, labelling it a "money grab."</p> <p><em>Image credits: Getty Images</em></p> <div style="box-sizing: border-box; margin: 0px; padding: 0px; border: 0px; font-family: 'Proxima Nova', system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Fira Sans', 'Droid Sans', 'Helvetica Neue'; font-size: 18px; font-style: normal; font-variant-caps: normal; font-weight: 400; font-stretch: inherit; line-height: inherit; vertical-align: baseline; caret-color: #333333; color: #333333; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"> <div class="ob-smartfeed-wrapper feedIdx-0" style="box-sizing: border-box; margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant-caps: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; vertical-align: baseline;"> <div id="outbrain_widget_0" class="OUTBRAIN" style="box-sizing: border-box; margin: 0px; padding: 0px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant-caps: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; vertical-align: baseline;" data-src="//celebrity.nine.com.au/latest/priscilla-presley-gets-emotional-after-very-difficult-viewing-of-priscilla/d6fd2f98-d746-4664-ada4-e5662a435aea" data-widget-id="AR_8" data-external-id="3820c6a948ab8b24c8020cab9d348600" data-ob-mark="true" data-browser="safari" data-os="macintel" data-dynload="" data-idx="0"> <div class="ob-widget ob-feed-layout AR_8" style="box-sizing: content-box; margin: 0px; padding: 0px 3px; border: 0px; font-family: inherit; font-size: inherit; font-style: inherit; font-variant-caps: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; vertical-align: baseline; position: relative; width: auto; min-width: 0px; clear: both;"> <div class="ob-widget-header" style="box-sizing: content-box; margin: 24px 0px 14px; padding: 0px; border: 0px; font-family: inherit; font-size: 18px; font-style: inherit; font-variant-caps: inherit; font-weight: bold; font-stretch: inherit; line-height: inherit; vertical-align: baseline; color: #303030; direction: ltr; display: flex; justify-content: space-between; align-items: center;"> </div> </div> </div> </div> </div>

What your glasses are secretly revealing about your personality

<p><strong>Colourful frames are for creative types</strong></p> <p>Glasses frames come in every imaginable colour nowadays. While black and brown frames still exist, they are no longer the only options. Those who do dare to colour their vision are typically very creative, says optometrist Lynn Green. “Artists love colour,” she says. “They are very particular with what they like and they know what they like.” But artists aren’t the only ones who gravitate towards colour frames. Both the extrovert and the introvert veer toward this kind of eye wear.</p> <p>“Usually bright, bold colours are somebody that’s fun and outgoing,” Green discerns, “but what’s nice about fun colours is somebody…who’s always been neutral and blends in, they’ve gotten to a point in their life where they’re like, ‘You know what, I need a change.’” While it is very natural for an outgoing person to pick up a pair of attention-grabbing glasses, shy people who are trying to break out of their shell can use these glasses as a means of putting themselves out there.</p> <p><strong>Thick black frames are trendy </strong></p> <p>Thick black frames go largely to the young, hipster crowd. The people who wear these glasses are definitely trying to make a statement about themselves. Green describes this type as, “That bold, ‘look-at-me’ frame.” It has been her observation that the dark, thick, heavier frames have been the favourite of people in the late teens to 20s age range.</p> <p>These are the glasses that are one of the biggest trends. A person that has a pair of these glasses is probably young, bold, opinionated, and trendy.</p> <p><strong>Patterned frames are cheerful </strong></p> <p>In terms of demographics, Green has also surmised that it is mostly women who tend to opt for colour and different patterns on their frames. Not only that, but bright colours with patterns are also preferred by older people who want to feel the fun of youth again.</p> <p>Sometimes they even have designs by the temples, like little flowers. These cute and stylish glasses express a cheerful nature and someone who doesn’t like to take life too seriously.</p> <p><strong>Aviators are for the adventurous </strong></p> <p>Another person who has an intimate relationship with fashion and eye wear is fashion designer Larisa Ginzburg. According to her, those who have a penchant for aviators are quite the adventurers. “If you’re a fan of the aviators frame, chances are you’ve always been a risk taker. Just like you, this style is classic, but not concerned with respecting the rules and will stand out in its modern reinterpretations.</p> <p>The wearer is an active, devoted person who knows what they want and they’re not afraid to live for the moment. An undying staple of coolness, aviator glasses are a favourite among outspoken people who don’t just talk, but walk the talk.” If you’ve got at least one pair of aviators, you’re the kind of person whose presence is always felt. You enter a room and people notice, and you usually end up being the life of the party.</p> <p><strong>Fake glasses are a confidence boost </strong></p> <p>Yes, people really do wear fake glasses, and it’s more common than you’d think. According to Green, the whole “glasses make you look smart” thing still applies. “I had a patient come in,” Green shares, “[and] she was going for a very important job interview. She did not have a prescription. She wanted glasses that made her look very confident, and we found the perfect Tom Ford classic look. She brought us all chocolate because she got the job, and she said it was the glasses that did it.”</p> <p>Other than just for career, there are a lot of reasons that people wear fake glasses. As Green observes, glasses are now just as much an accessory as they are a necessity. Like shoes or purses or earrings, people buy glasses to intentionally convey something about themselves. People who wear fake glasses are very concerned with how the world sees them and may be somewhat insecure. At the same time, they could also be fashionistas who want to complete their perfect look.</p> <p><strong>Simple, clean lines are pragmatic </strong></p> <p>We’ve talked a lot about the creative person, but what about people who are more logically, mathematically, or scientifically driven? In her two decades of being an optician, Green has noticed that these types of people tend to pay less attention to style and more attention to function.</p> <p>“They go for structure,” she says. “They’re very detail oriented. They usually go with a more simple, clean line look.” For this type of person, glasses are more about pragmatism and not so much about showing off.</p> <p><strong>Big round frames are quirky </strong></p> <p>These are the glasses that Green refers to as “The Harry Potter frames.” They’re not as common as they used to be, but people do still rock that big, circular frame. “In that round shape is a very classic style,” she says. “It’s old Hollywood.”</p> <p>People who wear these glasses in the modern era tend to be men in their 30s to late 40s, she explains.

Enfield</a>, <em><a href="https://theconversation.com/institutions/university-of-virginia-752">University of Virginia</a></em></p> <p>A patient of mine, once a marathon runner, now gets tired just walking around the block. She developed COVID-19 during the 2020 Christmas holiday and saw me during the summer of 2021. Previously, her primary care doctor had recommended a graded exercise program. But exercise exhausted her. After months of waiting, she finally had an appointment at our post-COVID-19 clinic at the University of Virginia.</p> <p>She is hardly alone in her extended search for answers. Studies suggest that <a href="https://doi.org/10.1016/S0140-6736(22)01214-4">from 10%</a> to <a href="https://doi.org/10.1016/j.eclinm.2022.101762">45% of COVID-19 survivors</a> have at least <a href="https://www.cdc.gov/coronavirus/2019-ncov/long-term-effects/index.html">one of the following symptoms three months after recovery</a>: fatigue, cough, shortness of breath, difficulty sleeping, difficulty with daily activities or mental fogginess, otherwise known as “brain fog.”</p> <p>There are many names for this condition: <a href="https://theconversation.com/long-covid-stemmed-from-mild-cases-of-covid-19-in-most-people-according-to-a-new-multicountry-study-195707">long COVID</a>, long-haul COVID, post-acute COVID-19 syndrome and chronic COVID. Patients report that their symptoms, or the severity of them, <a href="http://dx.doi.org/10.1136/bmjgh-2021-007004">fluctuate over time</a>, which <a href="https://theconversation.com/deciphering-the-symptoms-of-long-covid-19-is-slow-and-painstaking-for-both-sufferers-and-their-physicians-164754">makes diagnosis and treatment difficult</a>.</p> <h2>A response to infection</h2> <p>Researchers and doctors have seen <a href="https://doi.org/10.2340/16501977-2694">similar recovery patterns from other viruses</a>, including <a href="https://www.cdc.gov/vhf/ebola/about.html">Ebola</a> and Middle East Respiratory Syndrome, <a href="https://www.lung.org/lung-health-diseases/lung-disease-lookup/middle-eastern-respiratory-syndrome-mers">or MERS</a>, which is another coronavirus.</p> <p>This suggests that the illness we see following a bout with COVID-19 may be part of a patient’s response to the infection. But doctors and researchers do not yet know why some patients go on to have persistent symptoms.</p> <p>My clinical practice and academic research <a href="https://scholar.google.com/scholar?as_ylo=2022&amp;q=Kyle+Enfield&amp;hl=en&amp;as_sdt=0,47">focus on critically ill patients</a>. Most of my patients now are people who had COVID-19 with various levels of severity.</p> <p>I often tell these patients that we are still learning about this disease, which wasn’t part of our vernacular before 2020. Part of what we do at the clinic is help patients understand what they can do at home to start improving.</p> <figure><iframe src="https://www.youtube.com/embed/ype9O4rD3Gk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">For millions of Americans, COVID-19 is still a part of their lives.</span></figcaption></figure> <h2>Dealing with fatigue</h2> <p><a href="https://doi.org/10.1038/s41598-021-95565-8">Chronic fatigue</a> can greatly affect quality of life. Exercise limitations can have their roots in problems with the lung, heart, brain, muscles or all of the above.</p> <p>Graded exercise therapy works for some but not all patients. Graded exercise is the slow introduction of exercise, starting slowly and gradually increasing in load over time. Many are frustrated because they feel more exhausted after exercising or even doing the routine tasks of daily living. The lack of progress <a href="https://doi.org/10.1016/j.jpsychores.2019.109893">leads to feelings of depression</a>.</p> <p>The condition of feeling more exhausted after exercise <a href="https://www.cdc.gov/me-cfs/healthcare-providers/clinical-care-patients-mecfs/treating-most-disruptive-symptoms.html">is called post-exertional malaise</a>, which is defined as physical and mental exhaustion after an activity, often 24 hours later, that is out of proportion with the activity.</p> <p>For example, you feel good today and decide to go for a walk around the block. Afterward you are fine, but the next day your muscles ache and all you can do is lie on the couch. Some patients don’t even have the energy to answer emails. Rest or sleep do typically relieve the fatigue. There is no one-size-fits-all approach to treatment; the severity and frequency of post-exertional malaise varies from person to person.</p> <h2>Signs and symptoms</h2> <p>Fatigue following any illness is common, as is exercise intolerance. So when should you see a medical professional? Diagnostic testing for post-exertional malaise exists, but it’s not readily available to all patients. These questions may provide clues to whether or not you are experiencing it:</p> <ul> <li>Does it take more than one day to recover to your usual baseline activity?</li> <li>Do you feel unwell, weak, sleep poorly or have pain when recovering from activity?</li> <li>Are you feeling limited in your ability to do your daily tasks after activity?</li> <li>Does exercise activity affect you positively?</li> <li>Do you have soreness and fatigue after nonstrenuous days, or mental fatigue after strenuous or nonstrenuous activities?</li> </ul> <p>All of these can be clues to discuss with your primary care provider, who may want to do additional testing to confirm the diagnosis, such as a <a href="https://me-pedia.org/wiki/Two-day_cardiopulmonary_exercise_test">two-day cardiopulmonary exercise test</a>.</p> <p>Before your appointment, there are a few things you can do at home that may help.</p> <h2>Taking it easy</h2> <p>One of those techniques is pacing, or activity management, an approach that balances activities with rest.</p> <p>The <a href="https://www.rcot.co.uk/">Royal College of Occupational Therapists</a> and the <a href="https://ics.ac.uk/">Intensive Care Society</a>, both in the U.K., developed what they call the <a href="https://www.rcot.co.uk/conserving-energy">3Ps – Pace, Plan and Prioritize</a>.</p> <p>Pacing yourself means breaking down activities into smaller stretches with frequent breaks rather than doing it all at once. An example would be to climb a few steps and then rest for 30 seconds, instead of climbing all the stairs at once.</p> <p>Planning involves looking at the week’s activities to see how they can be spread out. Think about the ones that are particularly strenuous, and give yourself extra time to complete them.</p> <p>This helps with prioritizing – and recognizing those tasks that can be skipped or put off.</p> <h2>Focusing on the breathing</h2> <p>Some patients with long COVID develop abnormal breathing patterns, including shallow rapid breathing, known as hyperventilating, or breath-holding. Either of these patterns can make you feel short of breath.</p> <p>Symptoms of abnormal breathing patterns include frequent yawning, throat-clearing, experiencing pins-and-needles sensations, palpitations and chest pain. Don’t ignore these symptoms, because they can be signs of serious medical problems like <a href="https://www.cdc.gov/heartdisease/heart_attack.htm">heart attacks</a> and <a href="https://www.cdc.gov/heartdisease/atrial_fibrillation.htm">abnormal heart rhythms</a>. Once those are ruled out, it is possible to relearn to breathe properly.</p> <p>You can <a href="https://longcovid.physio/breathing-pattern-disorders">practice these techniques at home</a>. The simple version: Find a comfortable position – either lying down or sitting upright with your back supported. Place one hand on your chest and the other over your belly button. Exhale any stale air out of your lungs. Then breathe in through your nose and into your abdomen, creating a gentle rise in the belly.</p> <p>You should feel the hand resting on your belly button move up and down. Try to avoid short, shallow breaths into the upper chest. Slowly exhale all the air out of your lungs. The goal is to take around eight to 12 breaths per minute.</p> <p>Focus on a longer exhale than inhale. For example, inhale as described for a count of two, then exhale for a count of three, as a starting point. If you take one breath every five seconds, you will be breathing 12 breaths per minute. As you get more comfortable with this, you can increase the time to further reduce your breaths per minute.</p> <figure><iframe src="https://www.youtube.com/embed/tEmt1Znux58?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Box breathing is easy to learn and you can do it anywhere, anytime.</span></figcaption></figure> <p>A more advanced tool <a href="https://www.youtube.com/watch?v=a7uQXDkxEtM">is called box breathing</a>: Breathe in for a count of four to five, holding your breath for a count of four to five, breathing out for a count of four to five and hold that for a count of four to five.</p> <p>Long COVID patients who use these techniques show improvement in <a href="https://doi.org/10.1016/S2213-2600(22)00125-4">symptoms of breathlessness and sense of well-being</a>.</p> <h2>The road to recovery</h2> <p>The patient I referred to earlier did all of these things. As we worked with her, we discovered she had multiple reasons for her symptoms. In addition to overbreathing and symptoms of post-exertion malaise, she had a new cardiac problem, possibly related to her COVID-19 illness, that made her <a href="https://doi.org/10.1161/JAHA.121.024207">heart work less well during exercise</a>. Now she is recovering; while not back to marathon running, she is feeling better.</p> <p>Currently there is no cure for long COVID, though we hope research will lead to one. <a href="https://clinicaltrials.gov/ct2/results?cond=long+covid&amp;term=&amp;cntry=&amp;state=&amp;city=&amp;dist=">Clinical trials looking at potential therapies</a> are continuing. In the meantime, people should be cautious about using medications that are not proved to help – and if you’re having symptoms, get evaluated.<!-- Below is The Conversation's page counter tag.

8 nifty uses for leftover glass jars

<p>If your recycling bin is building up with leftover jars, scoop them out and salvage them. There are so many uses for leftover jars that you never need crowd out the rubbish again.</p> <p>Here are our eight favourites:</p> <p><strong>Vase</strong> – Leftover glass jars, especially long narrow ones (like the ones tomato passata come in) are ideal for small flower arrangements. Wild flowers or natives look especially good in these vintage inspired vessels.</p> <p><strong>Candle-holder</strong> – Forget expensive candle holders. Small glass jars are excellent for holding your tea-lights. Try different shapes and sizes grouped together for an eye-catching effect.</p> <p><strong>Hold-all</strong> – Need somewhere to store your pens/pencils or even the bits and bobs that make up your sewing kit? Try using a large glass jar. Added bonus? You can see everything you’ve stashed.</p> <p><strong>Drinking glass</strong> – If you’ve been to a trendy café recently, you may have had your drink served in a glass jar. It’s the new ‘in thing’ to do. Why not create the same vibe at home and serve your drinks in your leftover jars? Smoothies especially are great in jars. You can even cap them with the lid for drinks on the go.</p> <p><span style="text-decoration: underline;"><em><strong><a href="http://oversixty.com.au/lifestyle/diy/2014/12/diy-polka-dot-drinking-glasses/" target="_blank" rel="noopener">Related link: Make your own polka-dot drinking glasses</a></strong></em></span></p> <p><strong>Planter</strong> – If you’re a keen gardener, especially one with a small space to green up, you’re no doubt always on the lookout for planters. Larger sized glass jars can make a beautifully eye-catching display for small plants with succulents.</p> <p><strong>Storage container</strong> – If your jar still has a tightly fitted lid, why not use it to store other foods? Homemade foods like pesto and nut butters are especially good stored in air-tight glass containers while large jars make the perfect biscuit tin.</p> <p><strong>Gift</strong> – Bear with us! While handing over an empty glass jar probably isn’t the best idea, filling a pretty jar with some homemade goodies makes for an excellent gift. The dry ingredients for biscuits, a favourite slice or even something like homemade tea or dried herbs and spices can all be placed in a jar festooned with some ribbon and a card.</p> <p><strong>Related links:</strong></p> <p><span style="text-decoration: underline;"><em><strong><a href="http://oversixty.com.au/lifestyle/at-home/2014/08/a-guide-to-homemade-candles/" target="_blank" rel="noopener">A guide to homemade candles</a></strong></em></span></p> <p><span style="text-decoration: underline;"><em><strong><a href="http://oversixty.com.au/lifestyle/diy/2014/12/diy-3-fab-ways-to-upcycle-mason-jars/" target="_blank" rel="noopener">Great uses for Mason jars</a></strong></em></span></p> <p><span style="text-decoration: underline;"><em><strong><a href="http://oversixty.com.au/lifestyle/at-home/2014/06/how-to-create-your-own-flower-arrangements/%20%20%20" target="_blank" rel="noopener">How to create your own flower arrangements</a></strong></em></span></p> <p><em><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Image credit: Shutterstock</span></em></p>

Hollywood’s 15 best movies based on kids’ books

<p>Steven Spielberg’s recent film <em>The BFG</em> is the 12th adaptation of a Dahl book (11th, if you discount an animated “BFG,” done for British television, that aired in 1989). And because they have captured the imagination of people such as Spielberg and Tim Burton (<em>Charlie and the Chocolate Factory</em>) and Nicolas Roeg (<em>The Witches</em>), they tend to turn out quite nicely, thank you.</p> <p>As I see it, two of them belong on anyone’s short list of truly excellent big-screen interpretations of kid-lit classics. <em>Fantastic Mr Fox</em> and <em>James and the Giant Peach</em> make my cut here among the 15 best of all time.</p> <p>There are talking animal stories on my list, there are kind wizards and evil witches, there are boys and girls who must find the courage to fend for themselves. There are horses that can run like the wind, a robot from outer space.</p> <p>If your favourites aren’t here, apologies. And let me know what they are. Like a certain green ogre whose tale I include, your BFFC (big, friendly film critic) is all ears. This is a subjective list, after all. But it’s a list that abounds with magic and adventure, danger and delight.</p> <p><strong><em>Babe </em>(1995) </strong></p> <p>From Dick King-Smith’s 1983 children’s book <em>The Sheep-Pig</em> (published as<em> Babe: The Gallant Pig</em> in the US.), the film, co-written by <em>Mad Max</em>’s George Miller, received seven Oscar nominations, including one for best picture. It’s the tale of a pig who believes he is better-equipped to herd sheep, and who is befriended by a duck (who thinks he’s a rooster), a border collie and an ewe. James Cromwell is farmer Hoggett, and thanks to some innovative CG lip-synching and animatronics, Babe and company walk and talk without a hitch. A charmer.</p> <p><strong><em>The Black Stallion</em> (1979)</strong></p> <p>Based on Walter Farley’s 1941 classic and directed by Carroll Ballard, this beautiful horse-and-his-boy adventure begins with a dramatic shipwreck off the coast of North Africa. The boy (Kelly Reno) and the horse (an Arabian stallion) bond on a desert island, are eventually rescued, and find their way to America, where Black – thanks to the help of an old, forgotten jockey (Mickey Rooney) – proves himself lightning fast on the track. As the race announcer says, “He could be the greatest sensation in racing history!”</p> <p><strong><em>The Brave Little Toaster</em> (1987)</strong></p> <p>Jerry Rees’ animated feature, adapted from Thomas M Disch’s 1980 novel <em>The Brave Little Toaster: A Bedtime Story for Small Appliances</em>, answers the oft-asked question: Do household appliances have souls? OK, maybe not so often asked, but the film - nominated for the Sundance Film Festival Grand Jury Prize - answers anyway, with wit and whimsy, as the title character and four best buds (a vacuum cleaner, a lamp, a radio and an electric blanket) go on a quest to find their owner. David Newman wrote the score, Van Dyke Parks contributed songs, and influences from Busby Berkeley to Walt Disney to General Electric are homaged.</p> <p><strong><em>Coraline </em>(2009) </strong></p> <p>From Neil Gaiman’s 2002 Hugo-winning novella, a glorious - and gloriously spooky - story about a misfit girl who discovers a parallel and seemingly idyllic universe through a small door in her family’s creaky new home. Henry Selick, of <em>The Nightmare Before Christmas</em>, directed the stop-motion animated gem. Moral: Beware of loving moms with buttons for eyes.</p> <p><strong><em>Fantastic Mr Fox</em> (2009)</strong></p> <p>Wes Anderson’s meticulously staged, magically realised stop-motion adaptation of Roald Dahl’s 1970 book, about a wily fox, his painter wife, and an alliance of forest critters forced to do battle against some menacing farmers.</p> <p>Nominated for the animated feature Academy Award, it’s unique in modern-day ‘toons for Anderson’s decision to record his cast (George Clooney, Meryl Streep, and Bill Murray among them) together, in an outdoorsy, woodsy setting, rather than isolate each voice actor in a sterile studio sound booth.</p> <p>The chemistry and spontaneity is palpable, the detail of the scale-model sets astounding. And is there a more dapper dresser than Mr. Fox? We think not.</p> <p><strong><em>Harry Potter and The Prisoner of Azkaban </em>(2004)</strong></p> <p>The third entry in the film franchise based on J.K. Rowling’s series of boy-wizard best-sellers is the first to fully capture that Hogwarts magic on the big screen. Thanks go to Alfonso Cuaron, who took over the directing job from HP 1 and 2’s Chris Columbus. Cuaron’s skills as a visual storyteller are out of this world, a fact borne out by his best director Oscar win in 2014 for the space odyssey Gravity.</p> <p><strong><em>​Howl’s Moving Castle</em> (2004) </strong></p> <p>A young woman, a witch’s curse, a heroic wizard, an ambulatory steampunk castle - the fairy-tale elements come together with the grace and beauty that Japanese animation master Hayao Miyazaki is known for. An immersive and imaginative take on Diana Wynne Jones’ 1986 book.</p> <p><strong><em>The Iron Giant </em>(1999)</strong></p> <p>Ted Hughes wrote the 1968 novel (called <em>The Iron Man</em> in the UK), about a humongous robot from outer space and the Earth boy who befriends him. Brad Bird, who would go on to direct Pixar’s <em>The Incredibles</em> and <em>Ratatouille</em> (and the rollicking live-action <em>Mission: Impossible - Ghost Protocol</em>), oversaw the traditionally animated adventure, injecting energy and emotion into the Ike-era tale.</p> <p><strong><em>James and The Giant Peach </em>(1996)</strong></p> <p>Roald Dahl’s surreal yarn - first published in 1961 - follows our boy hero as his parents are killed, and he is sent to live with two impossibly cruel aunts. A man with a bag of magic crocodile tongues comes along, a withered peach suddenly swells to gigantic proportions, and James meets a septet of talking insects who live inside the fruit. What’s next? A trans-Atlantic journey – by peach – to view the skyscrapers of New York, of course. Henry Selick’s terrific stop-motion animated adaptation, with a soundtrack courtesy of Randy Newman.</p> <p><strong><em>A Little Princess </em>(1995)</strong></p> <p>“I am a princess – all girls are!” a defiant Liesel Matthews tells a severe Eleanor Bron in Alfonso Cuaron’s dazzling screen reading of the 1905 Frances Hodgson Burnett novel. Matthews plays Sara, a girl sent to boarding school when her father goes off to World War I. When news comes that he has been killed, the headmistress played by Bron makes the pampered schoolgirl scrub and toil for her keep, and sends her to a cold, uncomfortable space in the attic to live. But the stories Sara spins in secret captivate the other schoolgirls, and goodness and kindness win the day.</p> <p><strong><em>National Velvet</em> (1944)</strong></p> <p>Elizabeth Taylor is 12-year-old Velvet Brown, an English girl who wins a horse in a contest, and who - with the help of a wanderer played by Mickey Rooney - trains the gelding to compete in the Grand National Steeplechase. Nothing can stop the girl and her horse - not even the fact that girls can’t be jockeys, and when the rider’s true identity is found out, well, who knew Enid Bagnold’s 1935 novel was a stealth feminist tract?</p> <p><strong><em>Pinocchio </em>(1940)</strong></p> <p>Walt Disney’s adaptation of the 19th-century Carlo Collodi tale about a wooden puppet-turned-real-life-boy is one of the great cartoon features to emerge from the House of (Mickey) Mouse. Fun and frightening, an allegory about self-realization and social assimilation, the landmark animated film is full of iconic moments - the terrifying transformation on Pleasure Island, Geppetto’s journey with(in) Monstro the whale - and classic songs (“I’ve Got No Strings,” “When You Wish Upon a Star”). As Jiminy Cricket says, let your conscience be your guide.</p> <p><strong><em>Shrek </em>(2001)</strong></p> <p>William Steig’s smart and snappy 1990 picture book - about a profoundly ugly ogre who must win the heart of an equally unsightly princess - experienced a fairy-talelike transformation of its own, losing the book title’s exclamation point, but gaining kazillions of dollars as a DreamWorks Animation megahit.</p> <p>With Mike Myers’ supplying the voice of the big green galumph, and Cameron Diaz as the princess, Fiona (no longer ugly, at least not during daylight hours), and Eddie Murphy as the wisecracking tagalong “steed” (a donkey), the eye-popping, computer-animated film mashes up a bookshelf of fairy tales, and also merrily bashes up (as in parodies) the tropes and traditions of its more-established competition, the Walt Disney Studio.</p> <p>Diehard fans of author/illustrator Steig’s original work grumble about the liberties and lampooning going on in the movie, but it’s hard not to laugh - a lot - at what the filmmakers have wrought.</p> <p><strong><em>Watership Down</em> (1978)</strong></p> <p>Quiet and gentle and yet fierce in its depiction of how death shapes us all, the British animated hit based on Richard Adams’ 1972 novel follows a small band of rabbits on the run, forced to find a new warren before “the terrible thing” happens.</p> <p>The animals have their own laws, their own mythologies - and the voices of some wonderful British actors, including Denholm Elliot, Michael Hordern, John Hurt and Ralph Richardson.</p> <p>Set in rolling English countryside, with meadows and woods, with dangers from beast and man, this talking-animal cartoon has a poetry, and a profundity, that feels very real, indeed. Bonus points if you know the lyrics to <em>Watership Down</em>’s signature song, Art Garfunkel’s “Bright Eyes.”</p> <p><strong><em>The Wizard of Oz </em>(1939)</strong></p> <p>Not just one of the best film adaptations of a children’s book ever, but one of the best films ever, period. With a teenage Judy Garland as Dorothy Gale, the Kansas lass who rides a twister all the way to a magical Technicolor land, populated by Munchkins and flying monkeys and a seriously wicked witch. L. Frank Baum’s 1900 fantasy <em>The Wonderful Wizard of Oz</em> provided the rich source material, and Victor Fleming (with assists from several other directors) provided the Hollywood vision, casting a trio of unforgettable sidekicks - Ray Bolger’s Scarecrow, Jack Haley’s Tin Man, and Bert Lahr’s Cowardly Lion - to join Dorothy on her journey down the yellow brick road. Iconic.</p> <p>Which of these films was your favourite? How about your grandchildren? Let us know in the comments below.</p> <p><em>Written by Steven Rea.

10 worst movies based on TV shows

<p>There was a time when Hollywood executives were convinced that television would end the movie industry. They were certain no-one would want to pay for entertainment when there was free TV to watch.</p> <p>Both the film and television worlds not only survived but also thrived. To keep up with the growing demand for new products to film, the movie executives turned to the same industry they once feared. </p> <p>Television programmes were adapted into big screen productions. The trend continues with <em>Baywatch</em> being the latest feature film to draw on a TV show for inspiration.</p> <p>Some of the efforts worked while others should have been cancelled before being released. The following list includes some of the worst movies based on a TV show. </p> <p>The list is long but here are 10 of the worst:</p> <p><strong>1. <em>CHiPs </em>(2017)</strong></p> <p>Dax Shepard and Michael Pena should have been arrested for grand theft for their part in this robbery of the movie-going public.</p> <p>The effort to make this movie a spoof of the beloved TV show that ran from 1977-1983 might have worked had they had even one funny joke. No such luck as all the pair had to work with was a script - by Shepard - that banked on a running joke about masturbating to generate laughs.</p> <p>Shepard and Pena. Both are talented performers, but even those with skills can't milk laughs out of a script that is a lot like Los Angeles traffic. Most of the time it's moving at a slow pace but there are more moments when it just comes to a dead stop.</p> <p><strong>2. <em>The Honeymooners </em>(2005)</strong></p> <p>It was a monster mistake to make a film version of the 1955 series starring Jackie Gleason. As much as 75 per cent of what made the original <em>Honeymooners</em> such classic entertainment was Gleason. It was his bigger-than-life personality that made the show a classic. Cedric the Entertainer has skills but not enough to be a modern Ralph Kramden.</p> <p>This movie should have been sent right to the moon instead of into theatres.</p> <p><strong>3.<em> Lost in Space </em>(1998)</strong></p> <p>The biggest problem director Stephen Hopkins faced trying to adapt this '60s sci-fi series into a movie was that the original TV show never had a clear identity. In a span of three seasons, the TV show went from a serious space adventure to a cosmic goof.</p> <p>And, the film is just as big a cosmic goof.</p> <p>The casting of Gary Oldman as Dr Smith (the Snidely Whiplash of space hitchhikers) was smart but that's where the clever thinking left orbit. A convoluted script mixed with a bland Matt LeBlanc as Maj Don West should have forced the studio to have the prints lost in the space of a landfill.</p> <p><strong>4. <em>The Beverly Hillbillies </em>(1993)</strong></p> <p>Few films based on TV shows have featured so much talent and potential only to end up missing the mark so much. Director Penelope Spheeris was coming off her massive success with <em>Wayne's World</em> and put together a cast that included Diedrich Bader, Jim Varney, Cloris Leachman, Lily Tomlin and Dabney Coleman.</p> <p>The one thing everyone forgot was that the TV comedy, which started in 1962, was a painfully light sitcom that relied on juvenile jokes and backwoods humour. That's OK when it's free on TV and there are other shows to watch but not worth the cost of a ticket.</p> <p>This was a wee-doggies of a film (with the emphasis on dog).</p> <p><strong>5. <em>Inspector Gadget </em>(1999)</strong></p> <p>The only way this live-action version of the creative animated series could have been any worse is if the vanilla version of comedy, French Stewart, had played the robotic detective rather than Matthew Broderick. At least Broderick tried to bring the same kind of dry humour to the role that Don Adams had infused in the original series. Try being the operative word.</p> <p>Other than helping push some toys sales, <em>Inspector Gadget</em> had little worth. It was so bad that Broderick didn't return to the role for the sequel and was replaced by... French Stewart.</p> <p><strong>6. <em>Car 54, Where Are You</em> (1994)</strong></p> <p>It was impossible to figure out the audience this movie was trying to attract. The big screen version of the TV show came along more than 30 years after the original went off the air. The goofball script didn't come across as being aimed at an audience that would remember the TV cop comedy. And the youth target market would have only heard of the series from their parents.</p> <p>The only good thing to come out of it was that John C McGinley was able to rebound seven years later to help make the TV comedy Scrubs a hit. So far, no word on a big screen version of that medical sitcom.</p> <p><strong>7. <em>Dukes of Hazzard</em> (2005)</strong></p> <p>The entire movie comes across like star Johnny Knoxville is pulling a Jackass stunt on the audience, with a lack of funny jokes, good acting, interesting situations, human-like dialogue, anything really hazardous and the presence of Jessica Simpson.</p> <p><strong>8. <em>Starsky & Hutch</em> (2004)</strong></p> <p>Ben Stiller had to have a place on this list and it was his forgettable work with Owen Wilson that earned him the honour. Watching the two stumble along as the big screen versions of the cool TV detectives ended up being a form of police brutality. The only saving grace was... OK, there was no saving grace.</p> <p>A shootout with the <em>Dukes of Hazzard</em> guys wouldn't have been enough to save this disaster.</p> <p><strong>9. T<em>he Flintstones in Viva Rock Vegas</em> (2000)</strong></p> <p>The cast from the original films - which included John Goodman, Elizabeth Perkins, Rick Moranis and Rosie O'Donnell - was replaced by the likes of Mark Addy, Kristen Johnston, Stephen Baldwin and Jane Krakowski.</p> <p>It's the best decision ever made by the original cast members to consider the franchise to be extinct. The replacements helped push this franchise back into the Stone Ages of movies.</p> <p><strong>10. <em>Land of the Lost </em>(2009)</strong></p> <p>What would such a list be like without one Will Ferrell movie?

7 research-based resolutions that will help strengthen your relationship in the year ahead

<p>The new year is going to be better. It has to be better. Maybe you’re one of the <a href="https://www.finder.com/new-years-resolution-statistics" target="_blank" rel="noopener">74% of Americans</a> in one survey who said they planned on hitting the reset button on Jan. 1 and resolving to improve. Those <a href="http://maristpoll.marist.edu/marist-poll-national-results-analysis-4/" target="_blank" rel="noopener">New Year’s resolutions most commonly focus on</a> eating healthier, exercising, losing weight and being a better person.</p> <p>Admirable goals, to be sure. But focusing on body and mind neglects something equally important: your romantic relationship. Couples with <a href="https://doi.org/10.1111/j.1741-3737.2007.00393.x" target="_blank" rel="noopener">better marriages report higher well-being</a>, and one study found that having a better romantic relationship not only promoted well-being and better health now but that <a href="https://doi.org/10.1080/08952841.2020.1838238" target="_blank" rel="noopener">those benefits extend into the future</a>.</p> <p>The lesson is clear: Your relationship is important. Resolve to get it right.</p> <p>That doesn’t mean you have to be perfect. But here are seven resolutions based on recent psychological research that you can make this New Year to help keep your relationship going strong.</p> <h2>1. Set yourself up for success</h2> <p>Adjust your mindset so you see your relationship as a key <a href="https://doi.org/10.1111/j.1467-6494.2005.00373.x" target="_blank" rel="noopener">source of positive experiences</a>. <a href="https://scholar.google.com/citations?user=v2ai_5wAAAAJ&amp;hl=en&amp;oi=ao" target="_blank" rel="noopener">Psychologists like me</a> call this boosting your social approach motivation. Instead of merely trying to avoid relationship problems, those with an approach motivation seek out the positives and <a href="http://peplab.web.unc.edu/files/2020/11/Don-Fredrickson-Algoe-JPSP-In-press-Approach-Paper-In-Press-.pdf" target="_blank" rel="noopener">use them to help the relationship</a>.</p> <p>Here’s how: Imagine a conversation with your partner. Having more of an approach motivation allows you to focus on positive feelings as you talk and to see your partner as more responsive to you. Your partner gets a burst of positivity, too, and in return sees you as more responsive. One partner’s good vibes spill over to the other partner, ultimately benefiting both. After a year when your relationship may have felt unprecedented external strains, laying the foundation to take advantage of any positives is good place to start.</p> <h2>2. Be optimistic</h2> <p>While things in the past may not have always gone how you wanted, it’s important to be optimistic about the future. But the right kind of optimism matters. A <a href="https://doi.org/10.1111/pere.12342" target="_blank" rel="noopener">2020 research study</a> from <a href="https://cns.utexas.edu/directory/item/84-human-dev-family-sci/3008-farnish-krystan?Itemid=349" target="_blank" rel="noopener">Krystan Farnish</a> and <a href="https://cns.utexas.edu/directory/item/14-human-ecology/259-neff-lisa-a?Itemid=349" target="_blank" rel="noopener">Lisa Neff</a> found that generally looking on the bright side of life allowed participants to deal with relationship conflict more effectively – as they put it, better able to “shake it off” – than did those who were optimistic specifically about their relationship.</p> <p>It seems that if people focus all their rosy expectations just on their relationship, it encourages them to anticipate few negative experiences with their partner. Since that’s unrealistic even in the best relationships, it sets them up for disappointment.</p> <h2>3. Increase your psychological flexibility</h2> <p><a href="https://doi.org/10.1016/j.brat.2005.06.006" target="_blank" rel="noopener">Try to go with the flow</a>. In other words, work on accepting your feelings without being defensive. It’s OK to adjust your behaviors – you don’t always have to do things the way you always have or go the places you’ve always gone. Stop being stubborn and experiment with being flexible.</p> <p>A 2020 study by <a href="https://www.researchgate.net/profile/Karen_Twiselton" target="_blank" rel="noopener">Karen Twiselton</a> and colleagues found that <a href="https://doi.org/10.1111/pere.12344" target="_blank" rel="noopener">when you’re more flexible psychologically</a>, relationship quality is higher, in part because you experience more positive and fewer negative emotions. For example, navigating the yearly challenge of holidays and family traditions is a relationship minefield. However, if both partners back away from a “must do” mentality in favor of a more adaptable approach, relationship harmony will be greater.</p> <h2>4. It’s OK to put ‘me’ before ‘we’</h2> <p>It’s easy for some people to play the self-sacrificing martyr in their romantic relationship. If this sounds like you, try to focus more on yourself. It doesn’t make you a bad person or a bad partner. When you’re psychologically healthy, your partner and your relationship also benefit.</p> <p>Researchers have identified <a href="https://doi.org/10.1037/pspp0000231" target="_blank" rel="noopener">four main traits that are part of good mental health</a>: openness to feelings, warmth, positive emotions and straightforwardness. These traits help with being more clear about who you are, feeling better about who you are, expressing greater optimism and less aggression, exploiting others less and exhibiting less antisocial behavior. You can see how what’s good for you in this case would be good for your partner too.</p> <h2>5. Do something for your partner</h2> <p>But it’s not all about you. Putting your partner first some of the time and catering to your partner’s desires is part of being a couple. A 2020 study by <a href="https://carleton.ca/psychology/people/johanna-peetz/" target="_blank" rel="noopener">Johanna Peetz</a> and colleagues found that <a href="https://doi.org/10.1111/pere.12357" target="_blank" rel="noopener">prioritizing your partner</a> makes you feel closer to them, increases positive feelings, reduces negative ones and boosts perceived relationship quality.</p> <p>In the new year, look for ways to give your partner some wins. Let them get their way from time to time and support them in what they want to do, without exclusively prioritizing your own wants and needs.</p> <h2>6. Don’t be so hard on yourself</h2> <p>So many New Year’s resolutions focus on body image. Aspirations to eat better and work out often stem from the same goal: a hotter body. Yet, research from <a href="https://www.researchgate.net/profile/Xue_Lei8" target="_blank" rel="noopener">Xue Lei</a> shows that you may not really know what your partner wants you to look like.</p> <p><a href="https://doi.org/10.1111/bjop.12451" target="_blank" rel="noopener">Women tend to overestimate how thin</a> male partners want them to be. Similarly, men believe that female partners want them to be more muscular than women say they do. It may seem harmless, but in both cases individuals are more critical and demanding toward themselves, in part based on misreading what a partner truly desires.</p> <h2>7. Stay in touch</h2> <p>I saved the easiest item on the list for last: Touch your partner more. When <a href="https://www.researchgate.net/profile/Cheryl_Carmichael" target="_blank" rel="noopener">Cheryl Carmichael</a> and colleagues followed 115 participants over a 10-day period, <a href="https://doi.org/10.1177/1948550620929164" target="_blank" rel="noopener">they found that initiating and receiving touch</a> – things like holding hands, cuddling, kissing – were associated with both a boost in closeness and relationship quality. Importantly, being touched by your partner has the added benefit of making you feel more understood and validated. Who couldn’t use more of that in the coming year?</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/7-research-based-resolutions-that-will-help-strengthen-your-relationship-in-the-year-ahead-152349" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

Why the size of your glasses matters

<p>It can be frustrating when you’ve picked up your news glasses only to find the frame presses against your head or the glasses keep slipping down your nose. Getting the right pair of glasses isn’t just about the right prescription, finding a comfortable frame is also key to enjoying relaxed and (almost) perfect vision. So if you’ve ever suffered buyer’s remorse after a glasses purchase, here are the tips to follow so you always get the perfect fit for your new glasses.</p> <p><strong>The lens</strong></p> <p>In general, the thinner and lighter the lens, the more comfortable the spectacles will be to wear. If possible, choose a thinner lens so your glasses won’t feel as heavy on the nose and ears.</p> <p><strong>The nose bridge</strong></p> <p>As one of the few points of contact with your face, it’s important to carefully consider the comfort of the glasses’ nose bridge. You want the nose pads to sit solidly on your nose, otherwise they can quickly lose their grip and keep sliding down.</p> <p><strong>The sides</strong></p> <p>The sides of your spectacles shouldn’t press into your temples. Some people mistakenly believe pressure means the glasses fit properly, but there should never be any heaviness felt on the temples. You might feel some pressure behind the ear, but that’s ok as this keeps the weight of the glasses from being borne wholly by your nose.</p> <p><strong>The frame</strong></p> <p>As a general rule, when you look through your glasses it should be at the middle of the lens. The top of the frame should sit below the eyebrows but above the fold of the eye and the frame should not be much wider than your face.</p> <p><em>Image: Getty Images</em></p>

AI-based traffic control gets the green light

<p>At the end of my Melbourne street there’s a new system being installed for traffic management. I hadn’t even noticed the extra cameras, vehicle and pedestrian sensors, LiDAR and radar on the intersection, but these tools are all part of a larger system, with researchers hoping that a 2.5km section of Nicholson Street, in Carlton, will eventually be run by an artificial intelligence (AI).</p> <p>This might sound a little nerve-wracking to the average commuter, but these “smart corridors” are popping up around the world – systems that promise to provide us with less traffic and better safety. </p> <p>“Many cities around the world have dedicated corridors or smart motorways that are equipped with sensors, CCTV cameras and AI for predicting the traffic flow, speed, or occupancy at a specific moment in time,” says Dr Adriana-Simona Mihaita, an AI infrastructure researcher at the University of Technology Sydney, who was not involved in the research.</p> <p>“Accurate predictions will provide transport operators with the means to make informed decisions and apply new control plans, or adjust the current ones according to ongoing traffic or eventual disruptions.”</p> <p>Even without AI, <a href="https://www.vicroads.vic.gov.au/traffic-and-road-use/traffic-management/traffic-signals/how-traffic-signals-work" target="_blank" rel="noreferrer noopener">our current traffic light systems are complex technology</a>. Detectors under the road surface clock the presence of vehicles and determine whether the lights change, and how long the green lasts for. The “push button” changes the green walk display, and some detectors even determine how fast or slow the pedestrians are moving. This is all controlled – in Australia at least – by a system called SCATS, or <a href="https://en.wikipedia.org/wiki/Sydney_Coordinated_Adaptive_Traffic_System" target="_blank" rel="noreferrer noopener">Sydney Coordinated Adaptive Traffic System</a>.</p> <p>This is an “intelligent transport system”, but it’s not machine learning or AI. Think of it as a calculator, but the values being input are cars and pedestrians, not numbers. And SCATS does have its flaws. To start with, it’s unable to see cars coming – only registering them once they’ve arrived on the detector. And the system is also not particularly good at including other modes of transport such as trams, cyclists and pedestrians.</p> <p>This is where Nicholson Street – home to plenty of cyclists and the 96 and 86 trams – will come in handy.</p> <p>“With SCATS there are loop detectors that tell us how many cars are in the queue from all directions, but we don’t really see the number of cyclists, or pedestrians, and we don’t take their delays into account,” explains one of the researchers on this Nicholson Street project, University of Melbourne transport engineer Dr Neema Nassir.</p> <p>“As long as we build our environment around cars, and prioritise their right of way over other modes of transport, we are promoting people using that mode of transport.”</p> <p>Using 180-degree high-definition cameras, as well as a range of detectors (including the normal SCATS detectors), Nassir and the team of researchers are currently testing the AI system using this real-world data in a computer simulation.</p> <p>When the AI eventually starts testing and directing traffic in the real world, it will be done using “edge computing”. This means that the AI-based traffic optimisation will happen at the intersection or “node” rather than at a central system. With the sensors taking and analysing the data almost instantly, the lights might change if there are more pedestrians waiting, or a tram might get right of way if it’s running behind schedule.</p> <p>Nassir hopes the intersections will be safer, trams will run more evenly, and there will be less stopping for cars on the road.</p> <p>However, there might also be some hiccups on the way.</p> <p>Safety is the top priority for the system, with efficiency coming in second. This means that the AI will be more likely to cause traffic jams than accidents.</p> <p>“If everything goes wrong with the algorithm and with the computations, it’s more likely that we may end up with a gridlock as opposed to safety concerns,” Nassir says. “We’re talking about an intersection that is designed to be robust enough that it can operate even when the traffic lights are off.”</p> <blockquote class="wp-block-quote"> <p>The AI will be more likely to cause traffic jams than accidents.</p> </blockquote> <div class="newsletter-box"> <div id="wpcf7-f6-p197191-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.62 spai-bg-prepared init" action="/technology/ai-based-traffic-control/#wpcf7-f6-p197191-o1" method="post" novalidate="novalidate" data-status="init"> <p style="display: none !important;"><span class="wpcf7-form-control-wrap referer-page"><input class="wpcf7-form-control wpcf7-text referer-page spai-bg-prepared" name="referer-page" type="hidden" value="https://cosmosmagazine.com/technology/" data-value="https://cosmosmagazine.com/technology/" aria-invalid="false" /></span></p> <p><!-- Chimpmail extension by Renzo Johnson --></form> </div> </div> <p>Having humans in this scenario, who are able to stop if required, is actually helpful. Unlike an autonomous car, which needs to function in an almost <a href="https://www.youtube.com/watch?v=RVkLI9pPd24&amp;t=166s" target="_blank" rel="noreferrer noopener">unlimited number of circumstances</a> without a human behind the wheel, traffic systems are comparatively simple. And, if something was to go wrong, humans are able to make a judgement and stop or swerve if required. Plus, because SCATS is already automated, it means that that the commuters coming through Nicholson Street might not even notice the change.  </p> <p>But that presents another dilemma – is it okay to record all this extra information and send it through an AI to make decisions?</p> <p>“The most important type of sensors are high-definition cameras,” says Nassir. “These are mounted high on poles and have 180 degrees of coverage, up to 50 metres down each approach. These are coupled with image-processing software that can help us detect and register and classify different types of passengers.</p> <p>“We also work with the data from key cards on public transport . There are tight regulations and rules regarding this personal data. It is always anonymised and protected.”</p> <blockquote class="wp-block-quote"> <p>Because SCATS is already automated, the commuters might not even notice the change.</p> </blockquote> <p>Nassir says the cameras are not capable of being used for facial recognition. In a world where facial recognition is happening every time you <a href="https://mashable.com/article/police-try-to-unlock-handcuffed-man-iphone-face-id" target="_blank" rel="noreferrer noopener">open your phone</a> and <a href="https://www.choice.com.au/consumers-and-data/data-collection-and-use/how-your-data-is-used/articles/kmart-bunnings-and-the-good-guys-using-facial-recognition-technology-in-store" target="_blank" rel="noreferrer noopener">in stores like Bunnings and Kmart</a>, traffic lights are probably not the place we need to be too concerned about our privacy being invaded.</p> <p>“Several phone applications that are currently in use today are already collecting private mobility data, together with personal preferences and route choice patterns, which represent a deeper concern for daily transport choices,” says Mihaita.</p> <p>“Similarly, public parking areas in large shopping malls have automatic plate recognition capability and store daily information on all vehicles entering/exiting the malls, which could be seen as personal information shared with the consent given while entering the parking area.”</p> <p>But ethical issues don’t just stop at these records. According to Professor Toby Walsh, an AI researcher from the University of New South Wales, there’s a number of ethical questions we should be aware of as these systems become integrated into our daily lives.</p> <p>For example, if our traffic systems know who we are, it might not just be a case of prioritising cars over other forms of transport, but instead the rich over the poor, or the paying verses the non-paying.</p> <p>“At stake are fundamental issues of fairness and justice,” Walsh explains. “You might start having to trade off my journey time against your journey time. Who gets priority?</p> <p>“Then there’s an environmental ethical issue: are we encouraging people to make more individual car journeys by improving traffic flow? Should we actually be trying to discourage people from getting in cars, and encouraging them to Zoom for work or get public transport?”</p> <p>Although the Nicholson Street AI project is trying to balance the priorities of trams, pedestrians, cyclists and cars, <a href="https://www.unimelb.edu.au/newsroom/news/2022/march/worlds-smartest-traffic-management-system-launches-in-melbourne" target="_blank" rel="noopener">easing urban congestion</a> is also an important part of the project, and as Walsh says, “Traffic is like an ideal gas that expands to fill the roads available.”</p> <blockquote class="wp-block-quote"> <p>“You might start having to trade off my journey time against your journey time. Who gets priority?”</p> <p><cite>Professor Toby Walsh, UNSW</cite></p></blockquote> <p>Despite these questions, Walsh argues that even if AI isn’t perfect, humans are worse. He has been involved in the research for another AI intersection – a particularly busy roundabout in the south-west of Sydney.</p> <p>“A thousand people are going to die in Australia in the next year, caused by traffic accidents. Almost all of those accidents are caused by human stupidity. Almost all of those accidents wouldn’t happen if we ceded our human control and all of our misjudgements – all of our texting and drinking and driving – to machines,” he says.</p> <p>“There’s always going to be unintended consequences – random shit happens, and the death rates are never going to be zero. But it would be a small fraction of what it is today.”</p> <p><!-- Start of tracking content syndication.

Chu’s rom-com centres on the same event but zeroes in on the sweet love story between Rachel (Constance Wu) – an economics professor raised by a single mother – and Nick (Henry Golding), who is secretly a member of one of Singapore’s richest families.</p><p>Viewers get to spend more time with the main couple and become more invested in their relationship, set against a lavish, visually stunning backdrop.</p><p><strong>Mean Girls (2004)</strong></p><p>Did you know that <em>Mean Girls</em> was based on a 2002 self-help book called <em>Queen Bees and Wannabes</em>?</p><p>Luckily, Tina Fey switched up the genre – and incorporated her own high school experiences – for her screenplay.</p><p>The result is an endlessly rewatchable, incredibly quotable movie about cliques and bullying that also includes one of the all-time great teen movie casts, thanks to fantastic performances from Lindsay Lohan, Rachel McAdams, Amanda Seyfried, Lizzy Caplan and more.</p><p><strong>The Lord of the Rings Trilogy (2001 - 2003)</strong></p><p>Fans of <em>The Lord of the Rings</em> may consider its inclusion on this list somewhat controversial – J.R.R. Tolkien’s epic high-fantasy novel is beloved by many, after all.</p><p>But with a length of 1200 pages and a handful of slower-paced sections, it can also be hard to get through.</p><p>Though Peter Jackson’s influential film trilogy – <em>The Fellowship of the Ring</em>, <em>The Two Towers</em> and <em>The Return of the King</em> – is also quite long, it does a great job of condensing Tolkien’s dense and detailed mythology, making for a vivid, immersive and immense moviegoing experience.</p><p><strong>The Godfather (1972)</strong></p><p>This one is pretty obvious. Francis Ford Coppola’s <em>The Godfather</em> is widely considered one of the best films ever made, with everyone involved – from Coppola to cinematographer Gordon Willis and stars Marlon Brando, Al Pacino, James Caan and Robert Duvall – delivering career-best work.</p><p>Author Mario Puzo’s source material, on the other hand, with its pulpy prose and out-of-place subplots, never reaches the same operatic heights.</p><p><strong>Election (1999)</strong></p><p>Before there was <em>Big Little Lies</em>’ Madeline Martha Mackenzie, there was Tracy Flick. This fantastic early Reese Witherspoon role saw the star playing a super intense, Type A high school overachiever set on winning a class election.</p><p>Tom Perrotta’s black comedy novel of the same name – which finds Tracy going toe-to-toe with a jealous teacher (Matthew Broderick in the film) who wants to sabotage her campaign – is an interesting read, but on the shorter side.</p><p>The novel’s satire is drawn out better on-screen, making each drama-filled scene that much juicier.</p><p><strong>Jackie Brown (1997) </strong></p><p><em>Jackie Brown</em> is the only Quentin Tarantino film based on a book – and it’s also one of his best.</p><p>Adapted from prolific crime writer Elmore Leonard’s <em>Rum Punch</em>, <em>Jackie Brown</em> takes the opportunity to get creative with its source material. Case in point: the titular flight attendant-turned-smuggler (Pam Grier, in a critically acclaimed performance) was a white woman in the novel.</p><p>The result is a slick, lively homage to the ‘70s Blaxploitation films that Grier helped make famous.</p><p><strong>A Simple Favor (2018)</strong></p><p>Author Darcey Bell’s debut novel, <em>A Simple Favor</em>, is written as a tense, <em>Gone Girl</em>-esque thriller that’s more of a pale pastiche of the genre than a gripping page-turner.</p><p>For the film adaptation, director Paul Feig reinvented the story, and instead made the tale – about a small-town vlogger searching for her missing, enigmatic friend – a sharp and twisty black comedy.</p><p>Stars Anna Kendrick and Blake Lively are dynamite and deliver on the laughs. And we can’t forget the many covetable suits Lively dons on screen that sparked a thousand memes!</p><p><strong>Legally Blonde (2001)</strong></p><p>Elle Woods (another iconic Reese Witherspoon role) is a perfect protagonist. She’s smart, funny, ambitious and surprising on her quest to battle stereotypes and conquer Harvard Law School.</p><p>On the other hand, the novel is inspired by writer Amanda Brown’s own pretty negative experiences at law school, making it…kind of a drag.</p><p>It’s more mean-spirited and, frankly, less empowering than the film to the point where it feels like everything you love about the charming movie is missing from the page.</p><p>Thankfully, the movie took a different approach, which we can all be grateful for the next time we re-watch the “bend and snap” scene.</p><p><em>Image credits: Getty Images</em></p><p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/culture/12-movies-that-were-better-than-the-books-they-were-based-on?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

How do pigeons find their way home? We looked in their ears with a diamond-based quantum microscope to find out

<p>Homing pigeons are known for their uncanny ability to find their way home – navigating complex and changing landscapes. In fact, they do this so well they were used as a source of secure communication more than 2,000 years ago.</p> <p>Julius Caesar <a href="https://www.asor.org/anetoday/2017/11/not-just-birds">reportedly sent</a> news of his conquest of Gaul back to Rome via pigeons, <a href="https://www.ft.com/content/255b75e0-c77d-11e2-be27-00144feab7de">as did Napoleon Bonaparte</a> following his defeat by England in the 1815 Battle of Waterloo.</p> <p>We know pigeons use visual cues and can navigate based on landmarks along known travel routes. We also know they have a magnetic sense called “magnetoreception” which lets them navigate using Earth’s magnetic field.</p> <p>But we don’t know exactly <em>how</em> they (and other species) do this. In <a href="https://www.pnas.org/cgi/doi/10.1073/pnas.2112749118">research</a> published today in the Proceedings of National Academy of Sciences, my colleagues and I tested a theory that attempts to link magnetoreception in homing pigeons with tiny lumps of iron-rich material found in their inner ears.</p> <p>By using a new kind of magnetic microscope, we confirmed this isn’t the case. But the technology has opened the door for us to investigate the phenomenon in several other species.</p> <h2>The current hypotheses</h2> <p>Scientists have spent decades exploring the possible mechanisms for magnetoreception. There are currently two mainstream theories.</p> <p>The first is a vision-based “free-radical pair” model. Homing pigeons and other migratory birds have proteins in the retina of their eyes called “cryptochromes”. These produce an electrical signal that <a href="https://www.nature.com/articles/s41586-021-03618-9">varies depending on the strength</a> of the local magnetic field.</p> <p>This could potentially allow the birds to “see” Earth’s magnetic field, although scientists have yet to confirm this theory.</p> <p>The second proposal for how homing pigeons navigate is based on lumps of magnetic material inside them, which may provide them with a magnetic particle-based directional compass.</p> <p>We know magnetic particles are found in nature, in a group of bacteria called <a href="https://theconversation.com/magnetic-bacteria-and-their-unique-superpower-attract-researchers-100720">magnetotactic bacteria</a>. These bacteria produce magnetic particles and orient themselves along the Earth’s magnetic field lines.</p> <p>Scientists are now looking for magnetic particles in a range of species. Potential candidates <a href="https://link.springer.com/article/10.1007%2Fs00114-007-0236-0">were found</a> in the upper beak of homing pigeons more than a decade ago, but <a href="https://www.nature.com/articles/nature11046">subsequent work</a> indicated these particles were related to iron storage and not magnetic sensing.</p> <h2>A peek inside a pigeon’s ear</h2> <p>The new search is now underway in the inner ear of pigeons, where iron particles known as “cuticulosomes” <a href="https://www.sciencedirect.com/science/article/pii/S0960982213004338">were first identified</a> in 2013.</p> <p>Single cuticulosomes have been located within distinct regions in the pigeon inner ear where other known sensory systems exist (such as for hearing and balancing during flight). In theory, if there were a magnetic sensing system in pigeons, it should be located close to other sensory systems.</p> <p>But to determine whether iron cuticulosomes can act as magnetoreceptors in pigeons, scientists need to determine their magnetic properties. This is no mean feat, since cuticulosomes are 1,000 times smaller than a grain of sand.</p> <p>What’s more is they are only found in 30% of the hair cells within the inner ear, making them difficult to identify and characterise.</p> <p><a href="https://images.theconversation.com/files/431870/original/file-20211115-6434-uzv76r.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/431870/original/file-20211115-6434-uzv76r.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Diagram showing a homing pigeon's inner ear, with labels for hair cells and magnetic particles." /></a> <span class="caption">We conducted quantum magnetic imaging of iron-organelles in the pigeon inner ear.</span> <span class="attribution"><span class="source">Robert W de Gille</span>, <span class="license">Author provided</span></span></p> <p>To tackle this problem our group at the University of Melbourne, together with colleagues from Vienna’s Institute of Molecular Pathology and the Max Planck Society in Bonn, turned to a new imaging technology to explore the magnetic properties of iron cuticulosomes in the pigeon inner ear.</p> <p>We developed a magnetic microscope that uses diamond-based sensors to visualise delicate magnetic fields emanating from tiny magnetic particles.</p> <h2>Disproving the theory</h2> <p>We carefully studied thin sections of the pigeon inner ear placed directly onto the diamond sensors. By applying magnetic fields of varying strengths to the tissue, we were able to gauge the magnetic susceptibility of single cuticulosomes.</p> <p>Our results showed the magnetic properties of the cuticulosomes were not strong enough for them to act as a magnetic particle-based magnetoreceptor. In fact, the particles would need to be 100,000 times stronger to activate the sensory pathways required for magnetoreception in pigeons.</p> <p>However, despite the search for the elusive magnetoreceptor coming up short, we are extremely excited by the potential of this magnetic microscope technology.</p> <p>We hope to use it study a host of magnetic candidates across a variety of species including rodents, fish and turtles. And by doing so we can focus not only on cuticulosomes, but a range of other potentially magnetic particles.<!-- Below is The Conversation's page counter tag.
