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

<p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan.</p> <p>f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>.</p> <p>But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge.</p> <p>Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community.</p> <p>This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California.</p> <p>Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>.</p> <p>Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>.</p> <p>However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life.</p> <h2>Is the secret in our diet?</h2> <p>When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones.</p> <p>For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease.</p> <p>In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age.</p> <p>Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity.</p> <p>But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses.</p> <p>Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>.</p> <p>Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity.</p> <p>Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing.</p> <p>There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life.</p> <p>Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing.</p> <p>Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<!-- Below is The Conversation's page counter tag.

Clive Palmer's plans to build Titanic II resurface

<p>Just when you thought we'd exhausted all of the possible billionaire pet projects, Clive Palmer, the Queensland mining magnate with pockets deeper than the Mariana Trench, has once again proven us wrong.</p> <p>For more than a decade now, Palmer has harboured a peculiar obsession: resurrecting the ghost of the <em>Titanic</em>, the world's most infamous maritime disaster.</p> <p>Palmer wants to build <em>Titanic II</em>, because when you've got more money than you can count, why not embark on a maritime venture that's already synonymous with catastrophe?</p> <p>Palmer, with the audacity only wealth can afford, has been pushing for this <em>Titanic</em> replica since 2012. Not content with merely one failed attempt, he launched the project again in 2018. Now, after another six years and a global pandemic, he's dusting off his captain's hat and setting sail once more, announcing the <em>Titanic II</em>'s re-launch at the Sydney Opera House (because when you're Clive Palmer, a press conference venue like the local community centre just doesn't cut it).</p> <p>But why, you may ask? According to Palmer himself, it's a simple matter of economics: "I’ve got two options, either give my wife more money for shopping or spend it on the <em>Titanic</em> and I’m spending it on the Titanic because she’s shopped enough."</p> <p>Ah, yes, the age-old dilemma of whether to buy your spouse another designer handbag or fund a one-billion-dollar replica of a ship that sank over a century ago. We've all been there.</p> <p>Despite the naysayers who dismissed Palmer's dream as nothing more than the folly of a rich eccentric, he remains undeterred. Now, with the pandemic in the rearview mirror and cruise ships once again cruising, Palmer sees this as the perfect time to resurrect his <em>Titanic</em> dream. Because what better way to celebrate the end of a global health crisis than by building a monument to maritime tragedy?</p> <p>Palmer assures us that this time around, things will be different. The plans are similar to previous iterations, but now they comply with current regulations. Tenders are being sought, with plans to confirm a shipbuilder by year's end with the intention of setting sail by 2027.</p> <p>And what can prospective passengers expect from this seafaring spectacle? Well, according to Palmer's team, an eight-minute video featuring period costumes and a layout straight out of the early 1900s. Passengers will even be encouraged to dress the part (though that's not compulsory; nothing screams "fun vacation" like wearing corsets and three-piece suits in the middle of the ocean).</p> <p>But fear not, third-class passengers, you won't be left out of this <em>Titanic</em> experience. You'll get to enjoy stew and mash at communal dining tables, just like the good old days. Although, for those who prefer their meals without a side of historical accuracy, other options will be available. </p> <p>In amongst of all this, Palmer has grandiose visions of <em>Titanic II</em> as a symbol of world peace. “We all know how to make war," he announced at the press launch. "We get armies and we fund wars. People know about that. But it is a lot harder to make peace. To make peace you have got to stick with it every day. You progress inch by inch.</p> <p>“<em>Titanic ll</em> is something that can provide peace. It can be a ship of peace between all countries of the world. Millions have dreamt of sailing on her, seeing her in port and experiencing her unique majesty. <em>Titanic ll</em> will be the ship where those dreams come true.”</p> <p>So, as Palmer sets sail on his quixotic quest to recreate history, we can't help but wonder: Is <em>Titanic II</em> a testament to human ingenuity or just another billionaire's folly? Only time will tell. But if history has taught us anything, it's that sometimes, even the grandest dreams can end up at the bottom of the ocean.</p> <p><em>Images: Rod Eime / Wikimedia</em></p>

"Pathetic" fine for killer of beloved 40-year-old blue groper

<p>In a shocking act of disregard for both marine life and the law, a 26-year-old individual has plunged a spear into the heart of Sydney's Cronulla community by illegally spearing and killing the beloved blue groper known as Gus.</p> <p>Blue gropers, revered for their non-aggressive nature and inquisitive demeanour, have been the official fish of New South Wales since 1996, enjoying legal protection against spearfishing and commercial exploitation.</p> <p>After visiting and entertaining locals in the area for over 40 years, Gus, affectionately named by the community, met a tragic end at Old Park in Cronulla, a well-signed no-spearfishing zone. The incident has left the local community seething with anger and grief, prompting demands for harsher penalties and increased community education.</p> <p>A local Facebook post on the incident quickly garnered more than 100 comments and 500 reactions, reflecting the collective outrage of concerned locals. One individual expressed their frustration, saying, "Omg what an a**hole! I've been trying to find that groper for ages, and now I'll never get to see him. I hope this guy gets a massive fine."</p> <p>Witnesses to the distressing incident, including Tenielle Piek, reported the callousness of the spearfisherman to <a href="https://www.news.com.au/technology/environment/outrage-over-fishermans-pathetic-punishment-for-killing-iconic-blue-groper-in-cronulla/news-story/7dec503e9b95ec1fd8d7e7b0f8438036" target="_blank" rel="noopener">news.com.au</a>, who proudly displayed the lifeless groper. Piek lamented the loss of the "Labrador of the Sea" and the vulnerability of these tame and curious creatures to spearfishing. She fears that future generations may be deprived of the opportunity to experience these beautiful creatures in their natural habitat along the shores of Cronulla.</p> <p>Despite the gravity of the crime, the spearfisherman was initially handed a meagre fine of $500, sparking outrage among locals who believed the punishment to be woefully inadequate. NSW Fisheries then tacked on an additional $300, and while the culprit displayed remorse during the interview with fisheries officers and was a first-time offender, the community clearly still feels shortchanged by the leniency of the penalty.</p> <p>A spokesperson from the Department of Primary Industries claimed that the individual was provided with education and awareness material to understand the rules of spearfishing. However, the paltry $300 fine out of a potential $11,000 seems insufficient to deter future acts of this nature.</p> <p>As the investigation appears to conclude, the Cronulla community remains on edge, grappling with the inadequacy of the penalties issued. The tragic fate of Gus demands justice and a resolute commitment to preserving the delicate marine ecosystem. Anything less than a substantial deterrent risks further harm to these innocent creatures and the cherished natural beauty of Cronulla's shores.</p> <p><em>Images: Facebook</em></p>

Debate sparked over list of top 100 cities on the planet

<p>The best 100 cities on the planet have been revealed, with three Aussie cities making the final list. </p> <p>The list was compiled by as part of an annual report by <a href="https://www.worldsbestcities.com" target="_blank" rel="noopener">Resonance Consultancy</a>, who rated major capital cities on three main factors: liveability, lovability and prosperity, with dozens of factors taken into account.</p> <p>These include educational attainment, GDP per capita, poverty rate, the number of quality restaurants, shops and nightclubs, walkability, the number of mapped bike routes, quality parks and museums, as well as ratings from TripAdvisor and Google. </p> <p>The top ten chart features four cities on the Asian continent, four in Europe and two in the U.S.</p> <p>Sydney, Melbourne and Brisbane were all featured in the list, coming in at numbers 31, 35 and 57 respectively.</p> <p>Taking out the number one spot this year is London, dubbed the "capital of capitals" that "reigns over all global cities" as the best metropolis in the world. </p> <p>The study proclaims it as the most liveable and the most lovable mecca, solidified by its winning culture and education attainment.</p> <p>The report concludes, "Despite crippling Covid lockdowns and economic devastation. Despite Brexit. Despite a war in Europe. The city is more indomitable and part of the global discourse than ever. From the Queen's death, to last autumn's chaotic drama at 10 Downing Street that finally calmed down with Rishi Sunak becoming prime minister, only to take heavy local election losses this spring, London is rarely quiet these days."</p> <p>Here's the full list of top 100 cities in the world.</p> <p> 1 - London, England </p> <p>2 - Paris, France</p> <p>3 - New York, USA</p> <p>4 - Tokyo, Japan</p> <p>5 - Singapore</p> <p>6 - Dubai, United Arab Emirates</p> <p>7 - San Francisco, USA</p> <p>8 - Barcelona, Spain</p> <p>9 - Amsterdam, Netherlands</p> <p>10 - Seoul, South Korea</p> <p>11 - Rome, Italy </p> <p>12 - Prague, Czechia </p> <p>13 - Madrid, Spain </p> <p>14 - Berlin, Germany</p> <p>15 - Los Angeles, USA</p> <p>16 - Chicago, USA</p> <p>17 - Washington, D.C., USA</p> <p>18 - Beijing, China </p> <p>19 - Istanbul, Turkey </p> <p>20 - Dublin, Ireland</p> <p>21 - Vienna, Austria </p> <p>22 - Milan, Italy </p> <p>23 - Toronto, Canada</p> <p>24 - Boston, USA</p> <p>25 - Abu Dhabi, United Arab Emirates </p> <p>26 - Budapest, Hungary </p> <p>27 - São Paulo, Brazil</p> <p>28 - Riyadh, Saudi Arabia</p> <p>29 - Stockholm, Sweden </p> <p>30 - Munich, Germany</p> <p>31 - Melbourne, Australia </p> <p>32 - Lisbon, Portugal </p> <p>33 - Zürich, Switzerland</p> <p>34 - Seattle, USA</p> <p>35 - Sydney, Australia </p> <p>36 - Doha, Qatar</p> <p>37 - Brussels, Belgium </p> <p>38 - San Jose, USA</p> <p>39 - Bangkok, Thailand</p> <p>40 - Warsaw, Poland </p> <p>41 - Copenhagen, Denmark </p> <p>42 - Taipei, Taiwan </p> <p>43 - Austin, USA</p> <p>44 - Oslo, Norway </p> <p>45 - Osaka, Japan </p> <p>46 - Hong Kong, China </p> <p>47 - Tel Aviv, Israel </p> <p>48 - Athens, Greece</p> <p>49 - Frankfurt, Germany</p> <p>50 - Vancouver, Canada </p> <p>51 - San Diego, USA</p> <p>52 - Orlando, USA</p> <p>53 - Helsinki, Finland </p> <p>54 - Miami, USA</p> <p>55 - Buenos Aires, Argentina </p> <p>56 - Hamburg, Germany </p> <p>57 - Brisbane, Australia </p> <p>58 - Kuwait, Kuwait</p> <p>59 - Las Vegas, USA</p> <p>60 - Montreal, Canada </p> <p>61 - Glasgow, Scotland</p> <p>62 - Shanghai, China </p> <p>63 - Rio de Janeiro, USA</p> <p>64 - Auckland, New Zealand </p> <p>65 - Atlanta, USA</p> <p>66 - Houston, USA</p> <p>67 - Busan, South Korea</p> <p>68 - Philadelphia, USA</p> <p>69 - Naples, Italy </p> <p>70 - Denver, USA</p> <p>71 - Nashville, USA</p> <p>72 - Manchester, England </p> <p>73 - Dallas, USA</p> <p>74 - Liverpool, England</p> <p>75 - Minneapolis, USA</p> <p>76 - Mexico City, Mexico</p> <p>77 - Minsk, Belarus </p> <p>78 - Lyon, France </p> <p>79 - Portland, USA</p> <p>80 - Rotterdam, Netherlands </p> <p>81 - Bogotá, Colombia</p> <p>82 - Kraków, Poland</p> <p>83 - Valencia, Spain</p> <p>84 - Santiago, Chile </p> <p>85 - Birmingham, England</p> <p>86 - New Orleans, USA</p> <p>87 - Bucharest, Romania</p> <p>88 - Leeds, England</p> <p>89 - Muscat, Oman </p> <p>90 - Ottawa, Canada </p> <p>91 - Cologne, Germany </p> <p>92 - Charlotte, USA</p> <p>93 - Calgary, Canada </p> <p>94 - Nagoya, Japan  </p> <p>95 - Düsseldorf, Germany </p> <p>96 - Hanoi, Vietnam</p> <p>97 - Gothenburg, Sweden </p> <p>98 - Sapporo, Japan</p> <p>99 - Bilbao, Spain </p> <p>100 - Baltimore, USA</p> <p><em>Image credits: Getty Images </em></p>

Handkerchief or tissue? Which one’s better for our health and the planet?

<p><em><a href="https://theconversation.com/profiles/mark-patrick-taylor-11394">Mark Patrick Taylor</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> and <a href="https://theconversation.com/profiles/hester-joyce-122106">Hester Joyce</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a></em></p> <p>Maybe you have hay fever, COVID, a cold or the flu, and are reaching for a tissue or handkerchief.</p> <p>But which one’s better at stopping infections spreading? Which has a smaller environmental impact? Is it the hanky, which has been with us since at least Roman times? Or the more recent and widely-used paper tissue?</p> <p>You might be surprised at the results.</p> <h2>A short history of the handkerchief and tissue</h2> <p>Today, we think of hankies as something to wipe noses, and catch coughs and sneezes. But such a simple square of cloth has a complex history.</p> <p>In the first century, the Romans <a href="http://margaretroedesigns.com/wp-content/uploads/HandkerchiefHist.pdf">used</a> a <em>sudarium</em> (Latin for sweat cloth) to wipe off sweat, or to mask the mouth and face.</p> <p>Over time, people have used what we now call a handkerchief or hanky, as a head covering, as a veil and for disguise, to clean hands, for wounds and to staunch blood.</p> <p>Wealthy people have used them to signify class and manners, and for discretely wiping away phlegm rather than smearing snot on sleeves or down skirts. Royalty have used them to indicate wealth and power through their gifts of fine linen and silk handkerchiefs to favoured subjects. Henry VIII owned an extensive collection, some embossed with gold and silver.</p> <p>Handkerchiefs have also been <a href="https://www.bl.uk/collection-items/italian-handkerchief">markers of</a> love, fidelity and sexual preferences. In the late 19th century the “handkerchief code” was a system of colour coding and handkerchief placement used to indicate sexual preferences, <a href="https://www.refinery29.com/en-au/lgbtq-secret-handkerchief-code-language">which is still active</a> in LGBTQ+ communities today.</p> <p>We can <a href="https://www.euppublishing.com/doi/epub/10.3366/cult.2020.0214">trace the origins</a> of paper tissue to China in the 2nd century BC. But it wasn’t until the 1920s that tissue as we know it today <a href="https://www.kleenex.co.uk/kleenex-history">was developed</a> to remove make-up and wipe runny noses from hay fever.</p> <h2>So, which one is better for our health?</h2> <p>More than 100 years ago, a cloth hanky was considered a “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5248216/pdf/hosplond73063-0008b.pdf">little flag of Death</a>” because of the germs it carried and how it contaminated pockets it was left in. Later, we were urged to use a hanky <a href="http://resource.nlm.nih.gov/101449736">as</a> “coughs and sneezes spread diseases”.</p> <figure class="align-right zoomable"><figcaption></figcaption></figure> <p>Today, we know nasal secretions harbour cold-type viruses that can be <a href="https://onlinelibrary.wiley.com/doi/10.1002/jmv.22027">transferred</a> to a <a href="https://www.abc.net.au/health/talkinghealth/factbuster/stories/2011/06/02/3231404.htm">range of surfaces</a> – hands, handkerchiefs, tissues, door knobs, keyboards – sometimes surviving <a href="https://doi.org/10.1093/oxfordjournals.aje.a113473">long after</a> the initial exposure.</p> <p>So blowing your nose into a reusable cotton hanky, then touching another object, means these viruses can spread. Even if you put your cotton hanky in the wash immediately, you’d likely contaminate surfaces on the way, such as doorknobs, and use your infected hands to operate the washing machine.</p> <p>Viruses don’t tend to <a href="https://doi.org/10.1093/infdis/146.1.47">survive so long</a> on tissues. As long as you throw tissues away after using them, and don’t leave them lying around for others to pick up, the chance of passing germs to others from a used tissue is far lower.</p> <p>Then there’s the question of whether hankies or tissues are effective barriers to coughing and respiratory spray.</p> <p>Basic cloth coverings, such as handkerchiefs or bandannas, can catch sputum, as can tissues. But several studies have shown they do not effectively <a href="https://doi.org/10.1021/acs.nanolett.0c02211">filter</a> <a href="https://aaqr.org/articles/aaqr-13-06-oa-0201.pdf">respiratory aerosols</a>, or <a href="https://doi.org/10.1177/153567601001500204">stop you inhaling</a> pollutants, pathogens or <a href="https://doi.org/10.1016/j.ijheh.2018.03.012">small airborne particles</a>.</p> <h2>Which one is better for the planet?</h2> <p>If you want to look at environmental considerations, US company Ecosystem Analytics <a href="https://ecosystem-analytics.com/wp-content/uploads/2013/10/Complete-LCA-Facial-Tissue-Handkerchief.pdf">compared</a> resusable cotton hankies to disposable paper tissues using a <a href="https://doi.org/10.1007/BF02978505">lifecycle analysis</a>. It considered four measures of environmental impacts associated with production, transport, use and disposal:</p> <ul> <li> <p>climate change (sum of greenhouse gases: carbon dioxide, methane, water vapour, nitrous oxide and CFCs)</p> </li> <li> <p>ecosystem quality (chemical pollution of land and water)</p> </li> <li> <p>human health (carcinogenic and non‐carcinogenic toxicity to humans)</p> </li> <li> <p>resources (total energy requirements of non‐renewable energy and mineral extraction).</p> </li> </ul> <p>The verdict? Across the four measures, a cotton hanky had five to seven times greater impact than an equivalent tissue.</p> <p>And, by far, the greatest impacts were related to the production of each of these products, rather than using or disposing of them.</p> <p>If you’re still keen to use a cotton hanky, you could opt for organic cotton, which has a <a href="https://www.sei.org/publications/ecological-footprint-water-analysis-cotton-hemp-polyester/">lower ecological footprint</a> compared to standard cotton produced in the same location. But organic cotton production has <a href="https://www.nytimes.com/wirecutter/blog/is-organic-cotton-better-for-the-environment/">lower yields</a> than its conventional equivalent, meaning more land is needed to produce an equivalent amount, compounding the total environmental impact.</p> <p>If you want to feel better about using tissues, ones made from recycled material may be a better option. Their manufacture leads to <a href="https://doi.org/10.1007/s11367-013-0597-x">fewer</a> greenhouse gas emissions compared with making regular tissues.</p> <h2>The verdict</h2> <p>Wiping our noses with paper tissues we dispose of properly after use (and don’t store in our pocket), made from recycled material, is preferable from both a health and environmental perspective.</p> <p>But tissues don’t quite have the same panache as the historic and versatile cloth hanky.<!-- 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.

It is a vital part of many ecosystems and cultures. Yet human activities in the current era, sometimes called the “<a href="https://theconversation.com/did-the-anthropocene-start-in-1950-or-much-earlier-heres-why-debate-over-our-world-changing-impact-matters-209869">Anthropocene</a>”, are reshaping patterns of fire across the planet.</p> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">In our new research</a>, published in the Annual Review of Environment and Resources, we used satellite data to create global maps of where and how fires are burning. We calculated about 3.98 million square kilometres of Earth’s land surface burns each year. We also examined research spanning archaeology, climatology, ecology, Indigenous knowledge and paleoecology, to better understand the causes and consequences of fires.</p> <p>Our international team found strong evidence fires are burning in unexpected places, at unusual times and in rarely observed ways. These changes in fire patterns are threatening human lives and modifying ecosystems.</p> <p>But the future does not have to be bleak. There are many opportunities to apply knowledge and practice of fire to benefit people and nature.</p> <h2>Here’s how fire patterns are changing</h2> <p>Exploring multiple approaches and scales enables a deeper understanding of where, when and how fires burn.</p> <p>Satellite data provide evidence of changes in fire patterns at a global scale. <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020RG000726">Annual fire season length</a> increased by 14 days from 1979 to 2020 and <a href="https://www.nature.com/articles/s41586-021-04325-1">night fires</a>, which indicate fires that cannot be quickly controlled, increased in intensity by 7.2% from 2003 to 2020.</p> <p>Other changes are apparent only when we look at data from particular regions. An increase in fire size and the frequency of large fires has recently been observed in <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2103135118">forests and woodlands of the western United States</a>. Meanwhile fire-dependent grasslands and savannahs across <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14711">Africa</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL082327">Brazil</a> have experienced reductions in fire frequency.</p> <p>It’s also important to consider the timescale and type of fire when interpreting changes. In Australia, <a href="https://www.nature.com/articles/s41467-021-27225-4">satellite records show</a> the frequency of very large forest fires has increased over the past four decades. At longer time scales, <a href="https://link.springer.com/article/10.1007/s13280-020-01339-3">charcoal and pollen records</a> indicate the frequency of low-intensity fires <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">decreased in parts of southeastern Australia</a> following British colonisation in 1788.</p> <h2>Changes in fire affect air, land and water</h2> <p>Many animals and plants have evolved strategies that enable them to thrive under particular fire patterns. This means changes to fire characteristics can <a href="https://www.science.org/doi/10.1126/science.abb0355">harm populations and ecosystems</a>.</p> <p><a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12905">Large and intense fires</a> are reducing the available forest habitat preferred by the greater glider. But a <a href="https://theconversation.com/research-reveals-fire-is-pushing-88-of-australias-threatened-land-mammals-closer-to-extinction-185965">lack of fire can be problematic too</a>. Threatened species of native rodents can benefit from food resources and habitats that flourish shortly after fire.</p> <p>There is evidence that emissions from recent fires are already modifying the atmosphere. The historically exceptional 2019–20 Australian wildfires produced <a href="https://www.science.org/doi/10.1126/science.abe1415#:%7E:text=Intense%2C%20widespread%20bushfires%20in%20Australia,from%20a%20moderate%20volcanic%20eruption.">record-breaking levels of aerosols</a> over the Southern Hemisphere, as well as substantial carbon emissions.</p> <p>The <a href="https://www.nature.com/articles/s41893-020-00610-5">wildfire smoke-related health costs</a> of the 2019–20 wildfires in Australia included an estimated 429 smoke-related premature deaths as well as 3,230 hospital admissions for cardiovascular and respiratory disorders.</p> <p>Changes in fire patterns are modifying water cycles, too. In the western United States, <a href="https://www.pnas.org/doi/10.1073/pnas.2009717118">fires are reaching higher elevations</a> and having strong impacts on <a href="https://www.pnas.org/doi/10.1073/pnas.2200333119">snow</a> and water availability.</p> <p>New studies are revealing how the air, land and water that support life on Earth are connected by fires. Smoke plumes from the 2019–20 Australian wildfires transported nutrients to the Southern Ocean, resulting in <a href="https://www.nature.com/articles/s41586-021-03805-8">widespread phytoplankton blooms</a>.</p> <h2>Humans are responsible for the changes</h2> <p>Human drivers such as climate change, land use, fire use and suppression, and transportation and extinction of species <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">are causing shifts in fire patterns</a>.</p> <p>Increasing global temperatures and more frequent heatwaves and droughts increase the likelihood of fire by promoting hot, dry and windy conditions. A pattern of extreme fire weather outside of natural climate variation is already emerging in <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15388">North America</a>, <a href="https://link.springer.com/article/10.1007/s10584-014-1183-3">southern Europe</a> and <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac1e3a/meta">the Amazon basin</a>.</p> <p>Humans modify fire regimes by changing land use for agricultural, forestry and urban purposes. Until recent decades, large fires in tropical forests were uncommon. But <a href="https://www.nature.com/articles/s41586-021-03876-7">deforestation fires</a> used to clear primary forest for agriculture often promotes more frequent and intense uncontrolled fires.</p> <p>Humans have transported plants and animals across the globe, resulting in novel mixes of species that modify fuels and fire regimes. In many parts of the world, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1908253116">invasive grasses</a> have increased flammability and fire activity.</p> <p>Social and economic changes propel these drivers.

The truth about Queen Elizabeth II and Princess Diana’s relationship

<p><strong>The Queen and Diana</strong></p> <p>Queen Elizabeth II and her daughter-in-law, Princess Diana, were more alike than you may realise: They both gave their lives to public service, they were strong in their own ways, and both were devoted to their families and subjects alike. But Queen Elizabeth and Princess Diana were also very different. The Queen is silent and traditional; Diana was modern and outspoken.</p> <p>Lady Diana Spencer, an aristocrat with many links to the royal family tree, married the eldest son of Queen Elizabeth II, Prince Charles, in July 1981. They had two sons, Princes William and Harry, who are Queen Elizabeth’s grandchildren. After several publicly tumultuous years in their marriage, Charles and Diana divorced in 1996, and Princess Diana died the following year.</p> <p>What was the relationship between Queen Elizabeth and Princess Diana really like, though? Much of the information that’s been used to form the narrative is a bit lopsided. “There’s a fundamental asymmetry in what we know about this relationship,” says Arianne Chernock, an associate professor of history at Boston University focusing on modern British history and the monarchy. “Diana perhaps told too much – she disclosed quite a bit about her life and her private feelings and emotions to the press. The Queen throughout her reign has had a very different, much more careful, choreographed approach. And so we don’t know what the Queen thought of the relationship. In a way, Diana gets to narrate the story for us.”</p> <p>And although much hearsay has been written about how the two royals felt about each other, this is what we know from the women themselves about their complicated relationship.</p> <p><strong>When did Queen Elizabeth and Princess Diana meet?</strong></p> <p>The Queen had known Diana Spencer – or at least known of her – for most of the younger woman’s life. “The Spencers were a prominent family with close royal ties,” Chernock says. Diana’s father was an equerry, or personal attendant, to the Queen’s father, King George VI, and then to the Queen herself; her grandmother was a lady-in-waiting to Elizabeth’s mother. Queen Elizabeth and Prince Philip attended Diana’s parents’ wedding, and the Queen is the godmother of Diana’s younger brother, Charles.</p> <p>Princess Diana was born and spent her childhood at Park House, on the grounds of the royal estate in Sandringham, Norfolk. The royal family’s official website notes that, as neighbours, the families had known each other for many years. “In fact, Diana’s older sister [Lady Sarah] briefly dated Prince Charles before he met Diana,” Chernock says.</p> <p>As her royal biography notes, Diana first encountered Prince Charles in 1977. He’d been invited to the Spencer estate at Althorp, where the family had moved after Diana’s father became Earl Spencer in 1975.</p> <p>When they began dating, a marriage between Charles and Diana was hardly a given. So when was Diana introduced to the Queen as a potential partner for Charles? “The most sustained early interaction with the royal family came when she was invited to [royal Scottish country estate] Balmoral,” Chernock says. Viewers of Netflix’s The Crown will remember the 1980 meeting as the infamous “Balmoral test.”</p> <p>The Queen thought Diana quite suitable for Charles. “She was very much a hit with the royal family – they really warmed to her,” Chernock says. “Diana worked very, very hard to ingratiate herself and to model what she thought being a princess would entail, and she did it very successfully.”</p> <p>But this success would later come to backfire on Diana. “In retrospect, many would argue that she was not her authentic self during that visit, so she was more performing a role that she aspired to as opposed to being herself,” Chernock says. “She was working very hard to fit in. She was a city girl, and she pretended to love the country. She went out shooting. She did all of the things that she was supposed to do but that she actually did not enjoy.”</p> <p><strong>What was the relationship between Queen Elizabeth and Princess Diana like?</strong></p> <p>At first, everything went smoothly between the Queen and Diana. “We do know that both she and Philip thought that Diana, based on that experience in Scotland, was very acceptable,” Chernock says. “They encouraged this union.”</p> <p>Although they were not exactly close, the Queen approved of Charles’s choice – or rather, she approved of the woman she believed Diana to be. If she hadn’t given her stamp of approval, the relationship wouldn’t have moved forward. “The Queen has never left a recorded impression,” Chernock says. “She’s very tight-lipped. So we don’t know. We can’t access her diaries or her private thoughts. We can look at her actions and her behaviours; those are the clues we have.”</p> <p>As for Diana, she may have started to get the sense that she bit off more than she could chew. “I think after her initial romance in Scotland, she began to realise just how tricky the royal family would be and how ill-prepared she was to really be a full-fledged member of the family,” Chernock says.</p> <p><strong>How did Queen Elizabeth feel about Diana's engagement to Prince Charles?</strong></p> <p>The Queen had a sense that Diana could handle royal life, and not just because of her success at Balmoral. Additional proof came, ironically, in the way Diana was able to weather the storm of press and photographers who soon descended upon her, according to a 1981 Time magazine article announcing her engagement. The Queen had begun pressing Charles to propose, due in part to all the media attention, giving him an ultimatum to marry Diana by the summer of 1981 or not at all. “The idea of this romance going on for another year is intolerable to everyone concerned,” the Queen said, according to Time. And when the public announcement happened, Elizabeth was “beaming.”</p> <p>But things would take a darker turn for Diana as she moved into the royal apartments at Buckingham Palace in preparation for the wedding. “Diana was wanting more guidance and felt that the Queen could have offered that to her,” Chernock says. “So it’s a fishbowl kind of experience, very few people on the inside, and I think Diana did describe her experience as a profoundly lonely one and wished that especially women in the royal family had been more accessible, more available to her.”</p> <p>The Queen, though, might have seen things differently. “She may think she was very accessible – she may think she did what she could, given her role and given her commitments and constraints,” Chernock says. “Again, Diana gets to tell the story about the Queen.”</p> <p>We do have a glimpse of the Queen’s feelings on the matter. According to royal expert Ingrid Seward’s 2002 book The Queen &amp; Di, in March 1981, Elizabeth wrote a letter to a friend in which she said, “I trust that Diana will find living here less of a burden than is expected.”</p> <p>Of course, that’s not what happened – at least from Diana’s point of view. “She described the royal family as cold, heartless and unfeeling; unsympathetic,” Chernock says. “I don’t think she was ever singling out the Queen specifically, but certainly that was how she framed her encounters with the family, the firm.” (The firm is an informal title for the institution of the monarchy, of which the Queen is the head.)</p> <p><strong>What happened between Queen Elizabeth and Princess Diana after the wedding?</strong></p> <p>After Charles and Diana’s wedding on July 29, 1981, the Queen began to entrust Diana with royal responsibilities, showing that she had confidence in the new Princess’s ability to carry out her official duties. Diana’s first solo task was to represent the royal family at the funeral of Princess Grace of Monaco, which the Queen allowed her to take on even though Charles didn’t think it was a good idea. According to Andrew Morton’s 1992 book, Diana: Her True Story – In Her Own Words, the Princess recalled, “I went to the Queen, and I said, ‘You know, I’d like to do this,’ and she said, ‘I don’t see why not. If you want to do this, you can.’”</p> <p>The success at that event led to many more, and even the Queen could see that the Princess had a way with people that could buoy the monarchy’s popularity. “She was an asset, to a point, until she stole the show,” Chernock says. “Part of the challenge, though, for the Queen and especially for Charles, was that Diana, she shined so brightly that she really – not necessary intentionally – eclipsed those around her.”</p> <p>Diana’s star power affected Charles the most when they toured, but it impacted Elizabeth as well. “There was a bit of, I suspect, tension there because she’s the Queen,” Chernock says. “There was a complicated little dance they probably had to play with each other.”</p> <p><strong>How did the women's relationship change as the royal marriage declined?</strong></p> <p>Prince Charles and Princess Diana were mismatched from the start, and with their marriage crumbling, the relationship between Queen Elizabeth and Princess Diana was also headed for the rocks.</p> <p>In tapes from 1993, which were made public in 2004 and rereleased with the 2017 documentary, Diana: In Her Own Words that aired in the United Kingdom, the Princess said she was not given the support she needed when she went “sobbing” to ask the Queen for help with the marriage. “So I went to the top lady and said, ‘I don’t know what I should do,’” Diana said. “She said, ‘I don’t know what you should do.’ And that was it. That was ‘help.’”</p> <p>According to Seward in The Queen &amp; Di, although Elizabeth was initially sympathetic to Diana, eventually the stoic monarch felt that the emotional Princess was simply too much to handle. “A footman said, ‘The Princess cried three times in a half an hour while she was waiting to see you.’ The Queen replied, ‘I had her for an hour – and she cried nonstop.’”</p> <p>Unsatisfied, that’s when Diana turned to the press; specifically, the Morton book in 1992 (although Diana’s participation was kept a secret until after her death) and Diana’s 1995 BBC Panorama interview with Martin Bashir (who recently apologised for using deceitful tactics to get the interview). The royals, including the Queen, “thought she talked too much – they did not see that as in keeping with royal protocol; how much she disclosed,” Chernock says.</p> <p>Although Elizabeth was “stunned” that Diana revealed so much publicly, according to Seward, she had to keep quiet and couldn’t respond in turn with her own feelings. Elizabeth’s silence on the matter didn’t help her cause, however. “The Queen’s interior or inner life is often a mystery, which works well for her on some occasions and less so on others because it can lead to this more unsympathetic portrayal of her becoming the dominant one; when we really don’t know what was going on,” Chernock says.</p> <p><strong>How did Queen Elizabeth feel about Charles and Diana's separation and divorce?</strong></p> <p>As you’ve no doubt guessed, Queen Elizabeth wasn’t thrilled that the royal marriage was dissolving. “I think we can assume, based on many related conversations others had, that [the Queen] did not want a separation; that this was seen as dangerous to the throne, not in keeping with this moral platform the family tries to uphold or project,” says Chernock. “So I think they certainly felt this was unfortunate.”</p> <p>Princess Diana and Prince Charles separated in 1992, but as their separation dragged on for several years, Elizabeth thought it was time to put a formal end to things. In 1995, Buckingham Palace released a statement to the press: “After considering the present situation, the Queen wrote to both the Prince and Princess earlier this week and gave them her view, supported by the Duke of Edinburgh, that an early divorce is desirable. The Prince of Wales also takes this view and has made this known to the Princess of Wales. The Queen and the Duke of Edinburgh will continue to do all they can to help and support the Prince and Princess of Wales, and most particularly their children, in this difficult period.”</p> <p>The Queen’s thinking on the topic of divorce had evolved over time – after all, it was her uncle’s inability to marry divorcée Wallis Simpson that caused him to abdicate the throne to his brother. And then there was her lack of support for her sister, Margaret, who had wished to marry divorcé Peter Townsend in the 1950s.</p> <p>“When you look back at Queen Elizabeth’s strong reaction to her sister Margaret’s desire to marry a divorcé and her opposition to Margaret’s marriage to Townsend, we can see the Queen has certainly evolved in her thinking, and I suspect she has come to prioritise the happiness of her family members over time,” Chernock says, pointing to the fact that other royals have divorced and Prince Harry has married divorcée Meghan Markle. “I think she has become much less rigid in her approach to thinking about marriage and the royal family, and [in] recognising that the royal family serves its constituents most effectively when its members are fulfilled emotionally as well as in other capacities.”</p> <p>Charles and Diana divorced in 1996.</p> <p><strong>How did Queen Elizabeth react to Princess Diana's death?</strong></p> <p>Perhaps the lowest point for the Queen throughout her 70-year-reign was after Diana was killed in the car crash, just one year after her divorce from Prince Charles. Instead of immediately rushing back to London from Balmoral to comfort her people, Elizabeth chose to stay in Scotland to attend to her grieving grandchildren, William and Harry, who had just lost their mother. The fact that Elizabeth remained in seclusion angered her subjects and fuelled conspiracy theories about Diana’s death.</p> <p>“I think in private she probably was a much more supportive anchor for that family in their period of turmoil than she’s given credit for,” Chernock says. “This is just what I surmise, but how telling is it that Meghan and Harry named their daughter [Lilibet] after the Queen? Clearly, there’s a really strong bond and love there, and she must have been a support to Harry during that really difficult period around his mother’s death.”</p> <p>Prince William echoed this in the BBC documentary, Diana, 7 Days. “At the time, you know, my grandmother wanted to protect her two grandsons, and my father as well,” he said, recalling being grateful to have had “the privacy to mourn, to collect our thoughts, and to just have that space away from everybody.” William also said that Elizabeth “felt very torn between being a grandmother to William and Harry and her Queen role.”</p> <p>A letter from Elizabeth to one of her aides recently resurfaced, revealing the Queen’s personal feelings about Diana’s passing. “It was indeed dreadfully sad, and she is a huge loss to the country. But the public reaction to her death and the service in the Abbey seem to have united people around the world in a rather inspiring way. William and Harry have been so brave, and I am very proud of them,” the Queen wrote. “I think your letter was one of the first I opened – emotions are still so mixed up, but we have all been through a very bad experience!”</p> <p>A week after her death and the night before Diana’s funeral, the Queen came back to Buckingham Palace and made a rare live television speech about the Princess; a landmark moment for her reign. Her broadcast, though, was “much at the urging of Tony Blair, prime minister at the time,” Chernock says. “I think she was counselled, but she was receptive to it, and saw that that was the wise move, and she relented.”</p> <p><strong>How did Princess Diana impact Queen Elizabeth and the monarchy?</strong></p> <p>Diana’s death was a turning point for the monarchy – and for Queen Elizabeth herself, who subsequently developed a renewed connection with her people. “These are all lessons learned from the challenges of managing ‘the Diana affair’ and the fallout from that,” Chernock says. “I think it was a very challenging moment for the crown but also indicative of the crown’s resilience that they, and the Queen specifically, were able to weather that and gain new levels of popularity in the years after, when many were predicting the end of monarchy in the late 1990s.”</p> <p>The Queen herself has changed as well, at least a bit. She’s “trying to inject a little bit more spontaneity, a little bit more emotion, a little bit more connection into her delivery,” Chernock says. “She has a very different style from Diana – and I don’t think anyone would want her to be Diana – but she’s become more willing to bring some of her own personality into public.”</p> <p>In addition, “I think she has developed a much finer appreciation for messaging, for showing that she’s emotionally connected to her people and in touch, and trying to incorporate some informality, even though scripted, into her role,” Chernock says.</p> <p>Case in point: the opening ceremony of the 2012 London Olympics, in which the Queen performed in a James Bond skit. “That has Diana written all over it,” Chernock says.</p> <p>While her famous British “keep calm and carry on” attitude has helped the country withstand recent challenges – namely, a global pandemic – the Queen has also learned to adapt, even growing the royal family’s presence on social media. “I think the whole royal family, including Queen Elizabeth, took a lesson from Diana’s formula that works,” Chernock says. “The royal family is always trying to balance tradition and innovation in a way that makes sense. In large part, I think this has to do with Diana and the fact that she was able to show that informality works.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/culture/the-truth-about-queen-elizabeth-ii-and-princess-dianas-relationship" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

If the world were coming to an end, what would be the most ethical way to rebuild humanity ‘off planet’?

<p><em><a href="https://theconversation.com/profiles/evie-kendal-734653">Evie Kendal</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Last week, scientists announced that for the first time on record, Antarctic ice has failed to “substantially recover” over winter, in a “once in 7.5-million-year event”. Climate change is the <a href="https://theconversation.com/antarctica-is-missing-a-chunk-of-sea-ice-bigger-than-greenland-whats-going-on-210665">most likely culprit</a>.</p> <p>Petra Heil, a sea ice physicist from the Australian Antarctic Division, <a href="https://www.abc.net.au/news/2023-07-24/antarctic-sea-ice-levels-nosedive-five-sigma-event/102635204">told the ABC</a> it could tip the world into a new state. “That would be quite concerning to the sustainability of human conditions on Earth, I suspect.”</p> <p>And in March, a senior United Nations disarmament official <a href="https://press.un.org/en/2023/sc15250.doc.htm">told the Security Council</a> the risk of nuclear weapons being used today is higher than at any time since the end of the Cold War.</p> <p>Both warnings speak to concerns about Earth’s security. Will our planet be able to support human life in the future? And if not, will humanity have another chance at survival in space?</p> <h2>‘Billionauts’ and how to choose who goes</h2> <p>Over the past few years, we’ve witnessed the rise of the “billionaut”. The ultra-wealthy are engaged in a <a href="https://theconversation.com/billionaire-space-race-the-ultimate-symbol-of-capitalisms-flawed-obsession-with-growth-164511">private space race</a> costing billions of dollars, while <a href="https://www.forbes.com/sites/oliverwilliams1/2021/12/21/billionaire-space-race-turns-into-a-publicity-disaster/?sh=79056f7e5e4d">regular citizens often condemn</a> the wasted resources and contribution to global carbon emissions.</p> <p>Space – described in the <a href="https://www.unoosa.org/oosa/en/ourwork/spacelaw/treaties/introouterspacetreaty.html">Outer Space Treaty</a> as being the “province of all mankind” – risks instead becoming the playground of the elite few, as they try to escape the consequences of environmental destruction.</p> <p>But if we have to select humans to send into space for a species survival mission, how do we choose who gets to go?</p> <p>In Montreal last month, the <a href="https://irg.space/irg-2023/">Interstellar Research Group</a> explored the question: how would you select a crew for the first interstellar mission?</p> <p>A panel led by <a href="https://www.erikanesvold.com/">Erika Nesvold</a>, a co-editor of the new book <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&amp;lang=en&amp;">Reclaiming Space</a>, discussed the perspectives of gender minorities, people with disabilities and First Nations groups regarding the ideal composition for an off-world crew.</p> <p>I was on the panel to discuss my contribution to the book, which explores how we can promote procreation in our new off-world society, without diminishing the reproductive liberty of survivors.</p> <h2>The ultra-wealthy and reproductive slavery</h2> <p>The first step in deciding how to allocate limited spaces on our “lifeboat” is identifying and rejecting options that are practically or ethically unacceptable.</p> <p>The first option I rejected was a user-pay system, whereby the wealthy can purchase a seat on the lifeboat. A 2022 Oxfam report showed the investments of just 125 billionaires collectively contribute 393 million tonnes of carbon dioxide equivalent per year: <a href="https://www.oxfam.org/en/press-releases/billionaire-emits-million-times-more-greenhouse-gases-average-person#:%7E:text=Recent%20data%20from%20Oxfam's%20research,%C2%B0C%20goal%20of%20the">a million times more</a> than the average for most global citizens.</p> <p>If the ultra-wealthy are the only ones to survive an environmental apocalypse, there’s a risk they would just create another one, on another planet. This would undermine the species survival project.</p> <p>The second option I rejected was allowing a reproductive slave class to develop, with some survivors compelled to populate the new community. This would disproportionately impact cis-gender women of reproductive capacity, demanding their gestational labour in exchange for a chance at survival.</p> <p>Neither a user-pay system nor reproductive slave labour would achieve the goal of “saving humanity” in any meaningful way.</p> <p>Many would argue preserving human values - including equality, reproductive liberty, and respect for diversity - is more important than saving human biology. If we lose what makes us unique as a species, that would be a kind of extinction anyway.</p> <p>But if we want humanity to survive, we still need to build our population in our new home. So what other options do we have?</p> <h2>Reproduction and diversity</h2> <p>How can we avoid discrimination on the basis of reproductive capacity – including age, sexuality, <a href="https://theconversation.com/infertility-through-the-ages-and-how-ivf-changed-the-way-we-think-about-it-87128">fertility status</a> or personal preference?</p> <p>We could avoid any questions about family planning when selecting our crew. This would align with <a href="https://www.seek.com.au/career-advice/article/illegal-interview-questions-what-employers-have-no-right-to-ask">equal opportunity policies</a> in other areas, like employment. But we would then have to hope enough candidates selected on other merits happen to be willing and able to procreate.</p> <p>Alternatively, we could reserve a certain number of places for those who agree to contribute to population growth. Fertility would then become an inherent job requirement. This might be similar to taking on a role as a <a href="https://theconversation.com/surrogacy-laws-why-a-global-approach-is-needed-to-stop-exploitation-of-women-98966">surrogate</a>, in which reproductive capacity is essential.</p> <p>But what if, after accepting such a position on the mission, someone changed their mind about wanting children? Would they be expected to provide some sort of compensation? Would they be vulnerable to retaliation?</p> <p>The more we focus on procreation, the less diversity we will preserve in the species as a whole – especially if we deliberately select against diverse sexualities, disabilities and older people.</p> <p>A lack of diversity would also threaten the long-term viability of the new society. For example, even if we exclude all physiologically or socially infertile people from the initial crew, these traits will reappear in future generations.</p> <p>The difference is: these children would be born into a less accepting community. Cooperation will be essential for the new human society – so promoting hostility would be counterproductive.</p> <p>So, what options are left? Using a random global sample to select travellers might alleviate concerns about equity and fairness. But the ability of a random sample to maximise our survival as a species would depend on how large the sample can be.</p> <p>A global sample would minimise bias. But there’s a risk it might yield a crew without doctors, engineers, farmers or other essential personnel.</p> <h2>Random selection versus a points-based system</h2> <p>The best balance between competing needs might be a stratified random sampling method, involving randomly selecting survivors from predetermined categories. Reproductive potential might be one category. Others might focus on other elements of practical usefulness or contribution to human diversity.</p> <p>Another option is a points-based system, whereby different skills and characteristics are ranked in terms of their desirability. In this system, an elderly person who speaks multiple languages may score higher than a physiologically fertile young person, due to their ability to substantially contribute to language preservation and education.</p> <p>This does not entirely eliminate the potential for discrimination, of course. Someone would need to decide which traits are most desirable and valuable to the new human society.</p> <p>However we determine our lifeboat candidates, it should be carefully considered. In our attempt to “save humanity”, we must avoid sacrificing the very things that make us human.</p> <hr /> <p><em>Evie Kendal is a contributor to <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&amp;lang=en&amp;">Reclaiming Space: Progressive and Multicultural Visions of Space Exploration</a> (Oxford University Press)<!-- Below is The Conversation's page counter tag.

The 7 most addictive (and delicious) foods on the planet

<p><strong>Why we can't get enough</strong></p> <p>What is it about the three Cs: Chocolate, cheese and chips? For some reason, we can never get enough of them. But wanting to chow on a particular food is one thing, being addicted to it is another. Fact is, you can become addicted to a certain food, and you can blame your brain’s response to it. That’s because certain foods elicit a release of dopamine in the brain, which can lead to more cravings for that particular treat, especially when it comes to foods that are high in sugar, salt and/or fat. Addictive foods are ones that hit your brain right in its pleasure centre, ostensibly telling you that you need more, more, more.</p> <p>“When this pleasure/reward centre is stimulated, the brain starts secreting dopamine and other chemicals that make us enjoy the experience even more,” says registered dietitian Ashvini Mashru. “Because your brain loves the sensation caused by that dopamine release, it seeks more of it by creating cravings, that if listened to can cause a vicious cycle of addiction.”</p> <p><strong>Chocoholics take note</strong></p> <p>That bowl of Smarties sitting on your colleague’s desk is a delicious temptation, a crunchy chocolatey treat that’s hard to resist. What we know is that chocolate is one of the most addictive foods around because it binds to the same pleasure centres in the brain as alcohol and certain drugs, according to a 2011 study conducted by Drexel University.</p> <p>It also boasts a nice ‘mouth feel’, which stimulates oxytocin production, another feel-good hormone, according to Dan DeFigio, author of Beating Sugar Addiction for Dummies. “Over time, our brains start looking for that dopamine hit, and every time we eat chocolate, it reinforces that ‘wiring,’” he says.</p> <p><strong>More cheese please</strong></p> <p>If you’ve hovered over a cheese platter and piled up the cubes, you’ll be relieved to know that it’s not just you. Cheese, which is generally high in fat and cholesterol, also contains a substance called casomorphin that binds to the opioid or feel-good receptors in the brain.</p> <p>“Casomorphins attach to neurotransmitters in our brains and release dopamine, feel-good chemicals, that often lead us to wanting more,” says Dr Neal Barnard, author of The Cheese Trap. “While cheese does have its health benefits, it also can be seriously addictive.”</p> <p><strong>Carb fix</strong></p> <p>Reach into that bowl of potato chips, tortilla chips or pretzels over and over again, and you’ll know something is happening on the addiction front. And, while there’s no particular compound in these foods that bind to specific brain receptors to cause a euphoric, stimulating, or addictive behaviour, there’s something else at play.</p> <p>“Simple carbohydrates are seen as ‘addictive’ because they cause a quick glucose release, and this quickly increases a person’s energy, says nutritionist Celina Jean. “This energy will quickly be used up, and then you’ll be forced to eat more simple carbohydrates to keep your blood sugar raised.”</p> <p><strong>Oh, sweet sips</strong></p> <p>Not only do sugary soft drinks (including sweet tea) provide us with very little nutrients, but one 375mL can contain a staggering 43 grams of sugar. Like sugary treats, fizzy drinks can stimulate the release of dopamine. Add caffeine and you’re getting a double-energy hit.</p> <p>“Once you’re hooked on caffeine, you can suffer symptoms of withdrawal if you try to stop, including sluggishness, headaches and emotional distress,” says Mashru.</p> <p><strong>Pass the fries</strong></p> <p>Hot chips or French fries are typically crisp, hot and salty. This is a triple-threat that signals the tongue and the brain to eat more, Mashru says. The fat content in fries triggers receptors in our mouths that send a signal to our brain and gut reinforcing the desire to eat more.</p> <p>“These little potato sticks are also a comfort food,” Mashru says. “Therefore, every time you go through the line in a restaurant and see them on the menu, you may find the urge to order them as a side to your entrée irresistible.”</p> <p><strong>Ice cream, you scream</strong></p> <p>Cravings for ice cream can be insatiable – it’s all about the sugar content and creamy texture, and researchers agree that foods like ice cream, which is basically cream and milk, stimulate the brain in the same way drugs do, inducing behaviours that resemble addiction, says dietitian Keri Glassman.</p> <p>“The sugar ‘highs’ and ‘lows’ you experience are consistent with sugar ‘dependency’,” she says. “When your body gets used to sugar, you feel out of sorts when you consume less, which causes you to eat more.”</p> <p><strong>Pizza</strong></p> <p>Whether it’s the stringy salty mozzarella cheese, the fluffy dough or the sugar in the tomato sauce, pizza ranks first in food addiction, according to a recent University of Michigan study.</p> <p>That’s because when you eat it, your blood sugar zips up quickly and then when it drops, you feel hungry again and want more.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/the-most-addicting-foods-on-the-planet" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

All-electric homes are better for your hip pocket and the planet. Here’s how governments can help us get off gas

<p><a href="https://theconversation.com/profiles/esther-suckling-1220357">Esther Suckling</a>, <em><a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a></em></p> <p>If every Australian household that uses gas went all-electric today, we would “save” more than 30 million tonnes of carbon dioxide emissions over the next ten years. That’s because there are more than <a href="https://www.energynetworks.com.au/resources/fact-sheets/reliable-and-clean-gas-for-australian-homes-2/">5 million households</a> on the gas network, and the <a href="https://grattan.edu.au/report/getting-off-gas">avoided emissions per home</a> ranges from 5-25 tonnes over the coming decade, depending on the location.</p> <p>Most people would spend less money on energy too. Electric appliances use less energy than gas appliances to do the same job, making them cheaper to run.</p> <p>Our <a href="https://grattan.edu.au/report/getting-off-gas">new report</a> shows how much most households can save by switching from gas to electricity for heating, hot water and cooking. The extra cash couldn’t come at a better time: about <a href="https://www.rmit.edu.au/news/all-news/2023/may/hidden-energy-poverty">a quarter of Australian households</a> say they found it difficult to pay their energy bills this year.</p> <p>But many households face hurdles that stop them, or make it hard for them, to go all-electric. Governments could make it easier for people and bring emissions-reduction targets closer to reality.</p> <h2>Most households save by upgrading to electric</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?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/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=393&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=393&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=393&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=493&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=493&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532139/original/file-20230615-29-h20bv5.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=493&amp;fit=crop&amp;dpr=3 2262w" alt="A chart showing estimated savings for each household switching from gas to electricity, over 10 years, in each capital city" /></a><figcaption><span class="caption">Over 10 years, the estimated savings for each household switching from gas to electricity range up to $13,900 in Melbourne. It’s a flat $3,890 figure for Brisbane, rather than a range, because there’s no gas heating.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>Households in Melbourne tend to use more gas than those in other mainland capitals, mainly because the winter is so cold. Our report found Melburnians who replace broken gas appliances with electric ones, or move into an all-electric home, could save up to A$13,900 over ten years. Households with rooftop solar will save even more.</p> <p>It’s a similar story in most parts of Australia except the west, where gas is relatively cheap. This mainly reflects differences in the historical development of the gas markets between the west and east coasts.</p> <p>Getting off gas could also be <a href="https://www1.racgp.org.au/ajgp/2022/december/health-risks-from-indoor-gas-appliances">good for your health</a>. Several studies link cooking with gas to <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/gas-stoves-and-asthma-in-children">childhood asthma</a>.</p> <p> </p> <h2>Households face a series of hurdles</h2> <p>Renters make up nearly a third of all households, and they have little or no control over the appliances that are installed. As most electric appliances cost more to buy than gas ones – and the subsequent bill savings flow to tenants – landlords have little incentive to upgrade their properties from gas to all-electric.</p> <p>Apartment living can increase the level of complexity. Multi-unit dwellings often bundle gas bills into body-corporate fees, limiting the occupants’ incentive to go all-electric. There can also be space constraints in these buildings. Centralised electric heat pumps, for example, take up more space than centralised gas water heaters.</p> <p>Then there are households that simply can’t afford the upgrade. Induction stoves and heat pumps are more expensive than their gas equivalents, by up to a combined $2,000. This initial outlay will soon be recovered by cheaper energy bills, but that doesn’t help households that don’t have the cash up front. The <a href="https://melbourneinstitute.unimelb.edu.au/data/taking-the-pulse-of-the-nation-2022/2023/energy-poverty">12% of households that skipped meals</a> to pay their energy bills in the past year are the most likely to remain locked into high gas bills.</p> <p>Some people also simply prefer cooking with gas. Some think induction cooktops will be no better than the poor-performing electric cooktops they may have used in the distant past. Others haven’t ever heard of a heat pump for hot water.</p> <h2>Here’s how governments can help</h2> <p>Governments, both state and federal, should lower the hurdles on the path to all-electric homes -– to reduce people’s cost of living and to cut carbon emissions.</p> <p>As a first step, state governments should ban new gas connections to homes. In 2021, more than 70,000 households joined the gas network. Trying to shift households off gas while allowing new connections is like pouring water into a bucket with a hole.</p> <p>Then, governments should provide landlords with tax write-offs on new induction stoves and heat pumps for hot water, for a limited time. After that, they should require every rental property to be all-electric. Governments should pay to upgrade public housing to all-electric, where they are the landlords. And they should pay not-for-profits managing community housing to do the same.</p> <p>The federal government should help all households to spread the cost of electric appliances over time. It should subsidise banks to offer low-interest loans for home electrification, via the Clean Energy Finance Corporation.</p> <p>And governments should set out to change people’s preferences, from gas to electric. They should embark on a multi-decade communication campaign, not unlike the campaign to upgrade from analogue to digital television in the early 2000s.</p> <p>A key challenge will be shifting people’s ideas about the best way to cook. There are precedents. In Gininderry, a new all-electric suburb of Canberra, one developer recruited chefs to run demonstrations on induction cooktops at the display village. The proportion of potential homebuyers <a href="https://ginninderry.com/wp-content/uploads/2021/08/Ginninderry-2017-Householder-Attitudes-to-Residential-Renewable-Energy-Futures.pdf">willing to consider buying an all-electric home</a> rose from 67% to 88%.</p> <figure><iframe src="https://www.youtube.com/embed/K9ytSh5TM9M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Induction cooking with Chef David Wei at Ginninderry.</span></figcaption></figure> <h2>‘Green gas’ is no panacea: electricity is cheaper</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?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/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=3 2262w" alt="Chart comparing the cost of hydrogen to electricity over time, showing hydrogen is more expensive and will remain so for decades" /></a><figcaption><span class="caption">Hydrogen is more expensive than electricity and will remain so for decades.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>The gas industry has another solution in mind: instead of switching from gas to electricity, it suggests using “green gas” -– biomethane or “green” hydrogen. Biomethane is chemically identical to natural gas, but is derived from biological materials such as food waste, sewage or agricultural waste. Green hydrogen is made by using electricity to split water into hydrogen and oxygen.</p> <p>But both options are <a href="https://theconversation.com/hydrogen-where-is-low-carbon-fuel-most-useful-for-decarbonisation-147696">too expensive and too far away</a>. Under the most generous of assumptions, green hydrogen will only become cost-competitive with electricity after 2045. And there is not enough biomethane commercially available to replace gas in households.</p> <p>Meanwhile, more than three million Australian homes already run on electricity alone.</p> <p>Getting the five million homes that use gas to the same point won’t be easy. But with good policy, it is doable. For households, and the climate, there is much to be gained.<!-- Below is The Conversation's page counter tag.

How to beat the retirement blues

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

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

<p>One Sydney couple have taken their friends and family by surprise with their high-stakes gender reveal, where the father-to-be was apparently put under arrest by two police officers. </p> <p>Mina Ibrahim revealed their elaborate prank with a video posted to his TikTok account. Mina’s video begins with footage of the moment of his ‘arrest’, before it cuts to the TikToker at a later date, explaining that “that’s me being arrested at my baby’s gender reveal.” </p> <p>He goes on to share the full video, and a promise that the ending will answer any questions his viewers may have.</p> <p>In the clip, the parents-to-be can be seen talking to two uniformed NSW ‘police officers’, guests all around them, with Mina asking for onlookers to get their phones out. He then pushes one of the officers, telling them to leave, and both grab him before attempting to handcuff him, while his pregnant partner attempts to intervene. </p> <p>As family members rush to assist, one of the officers calls for everyone to calm down, then delivers news that takes them all by surprise - and delight - by telling them, “it’s a baby girl.” </p> <p>“So it was the cops who announced to everyone that I was having a baby girl,” present-day Mina informed his audience, before noting that there was a fake balloon inside to throw their guests off the surprise scent. </p> <div class="mol-embed" style="font-size: 16px; margin: 0px 0px 8px; padding: 0px; min-height: 1px; letter-spacing: -0.16px; text-align: center; font-family: graphik, Arial, sans-serif; background-color: #ffffff;"> <blockquote id="v34606683345148116" class="tiktok-embed" style="margin: 18px auto; padding: 0px; min-height: 1px; letter-spacing: -0.01em; position: relative; width: 605px; box-sizing: border-box; line-height: 1.15; overflow: hidden; text-size-adjust: 100%; font-family: proxima-regular, PingFangSC, sans-serif; max-width: 605px; min-width: 325px;" cite="https://www.tiktok.com/@mina.ibs/video/7232964823296773383" data-video-id="7232964823296773383" data-embed-from="oembed"><p><iframe style="letter-spacing: -0.01em; border-width: initial; border-style: none; width: 605px; height: 735px; display: block; visibility: unset; max-height: 735px;" src="https://www.tiktok.com/embed/v2/7232964823296773383?lang=en-GB&amp;referrer=https%3A%2F%2Fwww.dailymail.co.uk%2Fnews%2Farticle-12082153%2FGender-reveal-party-prank-sees-cops-arrest-father-be.html&amp;embedFrom=oembed" name="__tt_embed__v34606683345148116" sandbox="allow-popups allow-popups-to-escape-sandbox allow-scripts allow-top-navigation allow-same-origin"></iframe></p></blockquote> </div> <p>The prank attracted thousands of views online, with many flocking to his comments section to share their congratulations with the parents-to-be. </p> <p>Others, while thrilled for them and their happy news, were open about their concern, having fallen for the trick right along with the couple’s loved ones. </p> <p>“I fell for it and I was worried for your wife!!!,” one confessed. “I was freaking out hahahah you got me”.</p> <p>“I was worried too haha … you scared me,” another said. </p> <p>“Omygosh! I was ready to sue them coppas with you!” came one response, “but congratsss! What a way to reveal!”</p> <p>One other simply wanted to know if the entire situation was even allowed, believing that impersonating the police may not be. </p> <p>And another had simply been suspicious from the very start, noting “Broooo the whole time I was like … something ain’t right! He’s not carrying his gun”.</p> <p><em>Images: TikTok</em></p>

<p>While royal visits are usually the picture of poise and control, it turns out not even the royals are immune to the occasional awkward encounter. </p> <p>A video clip of Kate Middleton's meeting with Queen Margrethe II of Denmark has gone viral, with one eagle-eyed royal fan pointing out the Princess of Wales' awkward body language. </p> <p>The royal women met at Copenhagen's Christian IX's Palace in February 2022, with the clip of their photo opportunity appearing to show Kate shuffling her way closer to Margrethe.</p> <p>From the looks of it, Kate was trying her best to get closer to Margrethe for the photocall without calling too much attention to herself.</p> <p>The creator of the TikTok, a user named The Royal Watcher, dubbed her move the "princess shuffle" in a caption overlaying the clip. </p> <div class="embed" style="font-size: 16px; box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; vertical-align: baseline; width: 610px; max-width: 100%; outline: none !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7224879027796856069&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40l0velycatherine%2Fvideo%2F7224879027796856069%3Fq%3Dprincess%2520shuffle%2520kate%26t%3D1682646320804&amp;image=https%3A%2F%2Fp16-sign-va.tiktokcdn.com%2Fobj%2Ftos-maliva-p-0068%2F6b111c9a9e324bb080e1019c0b462902_1682173251%3Fx-expires%3D1682665200%26x-signature%3DXThPcF0FgDOfxoNwZLSE0qcVYfo%253D&amp;key=59e3ae3acaa649a5a98672932445e203&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>However, according to royal fan and commentator Amanda Matta, Kate's shuffle may have shown a crack in her usually collected public appearance.</p> <p>"I can honestly say that I haven't seen Kate do this move before. To me, it demonstrates the high level of consideration (to the point of overthinking) that she puts into her appearances. On that photocall with Queen Margarethe and Crown Princess Mary of Denmark, she seemed slightly nervous," Matta said. </p> <p>"While a bolder move would have been to simply take a step to the right, Kate instead chose to try to make the shift towards the Queen as surreptitious as possible," she added.</p> <p>"She was able to keep her eyes on the camera at all times as a result."</p> <p>"Normally I don't like so-called 'body-language analysis,' but the signals that Kate may have been feeling a bit daunted by the Queen's presence were overwhelming on this day! And who wouldn't be?" Matta added. </p> <p><em>Image credits: Getty Images </em></p>

“I didn’t want to come out!”: Spanish mountaineer emerges after 500 days underground

<p>When Spanish mountaineer Beatriz Flamini descended into her cave - and home for the next 500 days - the world was an entirely different place. </p> <p>COVID-19 restrictions were still enforced, Queen Elizabeth II was still alive and on the throne, war hadn’t been declared in Ukraine, and Flamini herself was only 48. </p> <p>She entered the cave on November 20 2021, and while she was forced to surface for eight days while repairs were made to a router - one used for transmitting audio and video - she spent that brief period isolated in a tent. </p> <p>And then, a year and a half later, a 50-year-old Flamini emerged from 230 feet underground outside of Granada, Spain. And while most would be eager for some sunshine and some company after such a stint, Flamini had an entirely different take, informing everyone that she had actually been sound asleep when her team came to collect her. </p> <p>“I thought something had happened,” she said. “I said, ‘already? Surely not.’ I hadn’t finished my book.”</p> <p>And when it came to whether or not she’d struggled while down there, Flamini was quite to declare “never. In fact, I didn’t want to come out!”</p> <p>To keep herself occupied during the marathon stay, Flamini tried her hand at a whole host of popular pastimes, from knitting to exercising, painting, knitting, and reading. The effort paid off, the days flying by as the determined mountaineer successfully lost track of time.</p> <p>“On day 65, I stopped counting and lost perception of time,” she explained. “I didn’t talk to myself out loud, but I had internal conversations and got on very well with myself.</p> <p>“You have to remain conscious of your feelings. If you’re afraid, that’s something natural, but never let panic in, or you get paralysed.”</p> <p>Flamini was given a panic button in case of emergency, but she never felt the need to use it. And while her support team were on hand to give her clean clothing, provide essential food, and remove any waste that had accumulated, they were not to talk to her.</p> <p>“If it’s no communication it’s no communication, regardless of the circumstances,” Flamini said of that particular decision. “The people who know me knew and respected that.”</p> <p>As for what comes next, Flamini will now be studied by a team of experts - psychologists, researchers, and the like - to determine what impact the isolation of her extended time below might have had on her. </p> <p><em>Images: Getty, Sky News</em></p>

Fergie reveals Queen’s tender personal advice before passing

<p>Sarah Ferguson has shared that she is reminded of Queen Elizabeth II’s advice when she walks the late monarch’s infamous corgis.</p> <p>Sarah, the Duchess of York, 63, appeared on <em>The One Show</em> to promote her latest book, A Most Intriguing Lady, and she has revealed that the dogs make her think about the “values” upheld by her late mother-in-law.</p> <p>“One thing I really love when I'm with them actually, cause I really think about HM and I just really think about the value system that she supported in this country,” the duchess told presenters Alex Jones and Jermaine Jenas.</p> <p>“And I remember she used to say, "Sarah there needs to be more kindness in the world, which would disarm malice".”</p> <p>The Duchess feels that everyone should “stop to remember those words with respect and affection for a great leader, who has now passed it to another great leader in her son”.</p> <p>“It's so funny to say that...straight off the corgis,” she continued. "But when I look at them I think "yes come on”.”</p> <p>She also mentioned she believes that the late Queen’s message can, and should be followed more broadly across the country.</p> <p>“And I think - so important - for the whole country to unite and uphold the values that for 72 years the monarch gave us all, really.”</p> <p>Sarah also admitted to feeling frightened that something could happen to the dogs as she walks them.</p> <p>“Because they're national treasures I'm terrified when they go out running," she told <em>The One Show</em>. “They chase everything. Straight into tress, bang, like that! I go "no, no, no, the nation loves you, stop, stop, stop chasing the squirrels”.”</p> <p><em>Image credit: Getty</em></p>

World-renowned chef shares strangest celeb requests

<p>World-renowned and chef-to-the-stars Jeff Schroeter has had the privilege of catering for some of the world’s biggest names and deepest pockets, and it hasn’t come without its share of surprises. </p> <p>While chatting on <em>I’ve Got News For You</em>, a <em>news.com.au</em> podcast, Schroeter has named some of the strangest requests to come through his kitchen, as well as the familiar faces behind them. </p> <p>First up came Anna Wintour, who has served as Vogue’s editor-in-Chief since 1988 and harbours a not-so-secret craving for tuna in a tin. </p> <p>“She used to dine at least once or twice a week and had a special table … but she’ll go through different phases [of eating],” Schroeter explained. </p> <p>“And during one phase, we had a beautiful tuna niçoise - everyone ate it,” he continued, before noting that “she didn’t like fresh tuna, so she used to bring her own canned tuna and hand it to the waiter, who handed it to the busboy, and [he’d] bring it down to the kitchen.</p> <p>“So I’d make this beautiful niçoise salad, and then open a tin of tuna, and just put it on top. And she loved it.”</p> <p>In another bizarre move by the fashion elite, German designer Karl Lagerfeld once arrived at one of Schroeter’s restaurants with a group of “about 10 to 12” and a request that sent the kitchen scrambling. </p> <p>According to Schroeter, Lagerfeld and his party had been in the mood for “an American hotdog with fries”. But there was just one problem - they didn’t “have any of that!” </p> <p>All was not lost, of course, with the staff managing to come up with a solution. Before the clock struck midnight, a local street vendor saved them with a quick hot dog sale. And in a tale as old as time, McDonalds came to the rescue with the chips. </p> <p>“We sent the other busboy to McDonald’s to buy the fries and come back,” Schroeter said, “we put it on plates, sent it out, and [Lagerfeld] said it was the best meal [he’d had] for a long time.”</p> <p>In what is arguably Schroeter’s most notable diner, Queen Elizabeth often stopped by for her favourite dish. While not particularly unusual on its own, the order served as a clear sign to the kitchen that they had a very royal request on their hands. </p> <p>Apparently, the “50 to 80” chefs who worked at London’s Savoy hotel alongside Schroeter could tell when they had a royal visitor, as “they’ve got heavily armed security guards coming through the kitchens with Alsatians.”</p> <p>“[The royals] always dine in one of the seven private banquet rooms, but we’d know it was the Queen because she always loved the peach Melba,” he went on to explain. “So we knew when there were seven to 10 peach Melbas going to a private room, the Queen must be in the house.”</p> <p>Schroeter also shared his experiences with pop royalty, opening up about the time he was hired - along with four other talented chefs - to cater for Madonna’s 37th birthday celebration. </p> <p>“She booked out the place [the Delano Hotel in Miami] for her birthday, security all around, and she flew in four chefs from around the country,” Schroeter said, “and she picked each one for a particular dish that she loves to eat.</p> <p>“And I was flown down for the one that I call ‘Madonna salmon’. It’s a particular type of salmon and we cut it as a butterfly, and we put it with crushed cucumber, dates, walnuts, shaved fennel, lemon juice, olive oil and sweet basil – then the whole dish just lightens the salmon.</p> <p>“It’s healthy, it’s good for you … It was brilliant, three days down there and all I had to do was one dish. It was the best function I’ve had.”</p> <p>Although he didn’t have the opportunity to properly chat to the music superstar, he came away with a good impression, telling <em>I’ve Got News For You </em>host Andrew Bucklow that she was a “lovely, lovely woman … especially when she knows you’re cooking her favourite dish.”</p> <p><em>Images: Getty, @sallyb_sbco / Instagram </em></p>
