Readers response: How do you handle changes in energy levels as you age?

<p>As we get older, our levels of energy, ability and agility can slowly start to decrease, making us change our day-to-day lifestyles. </p> <p>We asked our readers how they handle these changes, and the response was overwhelming. Here's what they said. </p> <p><strong>Margo Courtney</strong> - Eat clean and healthy and your body will reward you with heaps of energy and vitality. I have a very big green smoothie most days as one of my 2 meals, along with 2 litres of water a day, and I don't even need much sleep.</p> <p><strong>Ron Stubbs</strong> - Up at 8am, can’t be late for my walk in the sun, and feeling great. Don’t need afternoon snooze then. I’m 77.</p> <p><strong>Kristeen Bon</strong> - I don’t handle them. I flop on the couch most afternoons for a quick five minute interior eye check!</p> <p><strong>Sylvia Brice</strong> - I have an autoimmune disease so my levels of energy are way down. I do what l can in small bursts and rest when l need to. Luckily l read and craft so can always do them. It's very hard to adapt but that's life and l am so much better for off than younger people with my disease. Think positive.</p> <p><strong>Judie Fisher</strong> - Do chores in small stretches, and have regular breaks.</p> <p><strong>Diane Green</strong> - Adjust. I do what I can, and what I can't just has to wait.</p> <p><strong>Raymond Richards</strong> - As they told us at the heart clinic, if you have something you HAVE to do - do it first.</p> <p><strong>Janis St George</strong> - Listen to your body - rest awhile when you need to.</p> <p><strong>Kaylene Samuels</strong> - Have a SCAN.....

Making art is a uniquely human act, and one that provides a wellspring of health benefits

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/girija-kaimal-1486183">Girija Kaimal</a>, <a href="https://theconversation.com/institutions/drexel-university-1074">Drexel University</a></em></p> <p>When you think about the word “art,” what comes to mind? A child’s artwork pinned to the fridge? A favorite artist whose work always inspires? Abstract art that is hard to understand?</p> <p>Each of these assumes that making art is something that other people do, such as children or “those with talent.”</p> <p>However, as I explain in my book “<a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&amp;lang=en&amp;cc=ca">The Expressive Instinct</a>,” art is intrinsic to human evolution and history. Just as sports or workouts exercise the body, creating art exercises the imagination and is essential to mental as well as physical well-being.</p> <p>I am a <a href="https://scholar.google.com/citations?user=C8R2XOYAAAAJ&amp;hl=en">professor of art therapy</a> who studies how creative self-expression affects physical and emotional health. In our clinical research studies, my colleagues and I are finding that any form of creative self-expression – including drawing, painting, fiber arts, woodworking or photography – can <a href="https://doi.org/10.1080/08322473.2017.1375827">reduce stress</a>, improve mood and increase self-confidence.</p> <p>As a sickly child who needed to stay home from school a lot, I found that making art helped me cope. Today, creating art is my sanctuary. I use it as a sounding board to better understand myself and a way to recharge and learn from the challenges of life.</p> <h2>The uniquely human attribute of creativity</h2> <p>Although everyone has their own concept of what defines art, one thing is universally true: Creativity is a defining feature of the human species.</p> <p>How so? Well, human brains are not computers processing data. They are biological prediction machines that perceive the environment through memories and the senses, with the capacity to <a href="https://doi.org/10.3389/fnhum.2010.00025">use that information to imagine</a> plausible future scenarios.</p> <p>These inherent predictive and imaginative capacities are the wellspring of humanity’s abilities to survive and thrive – because self-expression is a safety valve that helps us cope with uncertainty. No one truly knows the future; they must live each day not sure of what will happen tomorrow. Art can help us all practice this imaginative muscle in a useful way.</p> <p>In our study examining brain activity while using virtual reality tools to create 3-D digital artwork, my team demonstrated that <a href="https://doi.org/10.1080/07421656.2021.1957341">creative expression is a natural state of being</a>. The brain naturally uses fewer cognitive resources to be expressive and creative, compared with the <a href="https://doi.org/10.1080/07421656.2021.1957341">brain power needed to do a rote task</a> that requires conscious effort.</p> <p>Seemingly ordinary everyday activities can provide opportunities to tap into one’s natural creativity and imagination: whipping up a meal from leftovers, figuring out an alternate route to work, dancing a little jig in response to hearing a song, or planting and tending a garden.</p> <p>We have repeatedly found in our studies that even a single session of real and honest self-expression can improve self-confidence and <a href="https://doi.org/10.1177/1534735420912835">reduce feelings of stress</a>, <a href="https://doi.org/10.1016/j.ejon.2019.08.006">anxiety and burnout</a>.</p> <p>This is partly because <a href="https://doi.org/10.1016/j.aip.2017.05.004">creativity activates reward pathways</a> in the brain. Using our hands and bodies to express ourselves activates dopamine pathways and helps us feel good. Dopamine is a neural messenger that is associated with feeling a <a href="https://doi.org/10.1016%2Fj.ajpath.2015.09.023">sense of hope, accomplishment or reward</a>. Our brains are wired to secrete <a href="https://theconversation.com/why-does-experiencing-flow-feel-so-good-a-communication-scientist-explains-173505">feel-good hormones whenever we move</a>, create something or engage in any type of expressive activity.</p> <p>Tapping into the creative resources within is <a href="https://theconversation.com/drawing-making-music-and-writing-poetry-can-support-healing-and-bring-more-humanity-to-health-care-in-us-hospitals-204684">one of the most underrated seeds of well-being</a> in the world.</p> <p>By comparison, bottling up or <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">denying these feelings can cause distress</a>, anxiety and fear because we have not processed and expressed them. This is probably one of the reasons why every community around the world has its own creative and expressive practices. Even our ancestors in Indigenous communities all around the world intuitively knew that <a href="https://doi.org/10.1016/j.aip.2021.101879">self-expression was essential</a> to emotional health and social connection.</p> <p>Being unable to share our lives, <a href="https://www.scientificamerican.com/article/why-the-secrets-you-keep-are-hurting-you/">keeping secrets</a> and feeling isolated and lonely tend <a href="https://doi.org/10.1016/j.neubiorev.2020.02.002">to worsen our health</a>. To our brains, social isolation feels like a chronic disease because it interprets this loneliness and inability to express as a threat to survival.</p> <p>Since creative expression can engage the senses, it can also be a body workout: a sensual as well as emotional and cognitive experience. Being active in expression – be it art, music, dance, drama, writing, culinary arts or working with nature – imparts a sense of confidence and hope that <a href="https://global.oup.com/academic/product/the-expressive-instinct-9780197646229?q=the%20expressive%20instinct&amp;lang=en&amp;cc=ca">challenges can be navigated and overcome</a>.</p> <h2>The role of art therapy</h2> <p>Given the integral role of art in our lives, it makes sense that making art can help people manage transitions, adversity and trauma, such as the stresses of puberty, the death of a loved one or <a href="https://doi.org/10.1016/j.ejon.2019.08.006">experiencing a serious illness</a>.</p> <p>According to a global study, 1 in 2 people will experience a <a href="https://doi.org/10.1016/S2215-0366(23)00193-1">mental-health-related challenge in their lifetime</a>, whether from life’s challenges, genetic predispositions or a combination of the two.</p> <p>This is where art therapy can come in. Art therapy is <a href="https://arttherapy.org/about-art-therapy/">a regulated mental health profession</a> in which clinical psychotherapists with extensive clinical training offer psychotherapy to patients with diagnosed mental health needs.</p> <p>The origins of art therapy go back to <a href="https://doi.org/10.1136/bmjopen-2017-021448">attempts to treat soldiers struggling with post-traumatic stress</a> during the 20th century’s two world wars. Today there is evidence that traumatic experiences tend to be stored as <a href="http://orcid.org/0000-0002-7316-0473">sounds, images and physical sensations</a> in the brain. When someone <a href="https://doi.org/10.1001/jama.2019.20825">lacks the words</a> to process these experiences through traditional talk therapy, art therapy can provide an indirect way to express and externalize those feelings and memories.</p> <figure><iframe src="https://www.youtube.com/embed/e-IiUcUVAwk?wmode=transparent&amp;start=3" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The process of making art can help people process feelings that they aren’t able to put into words.</span></figcaption></figure> <p>One of art therapy’s unique strengths is that it provides nonverbal ways of communicating, processing and eventually managing the symptoms of post-traumatic stress disorder, or PTSD. In fact, in a recent study, my team has found that a personal history of trauma is related to <a href="https://doi.org/10.3389/fpsyg.2024.1337927">how people react to evocative images</a>. Images of distress and pain resonate with us when we have known similar kinds of distress ourselves. This implies that our life stories make us sensitized to distress in others and even personalize it more.</p> <p>Creative self-expression is especially relevant in coping with trauma because it provides an outlet through which a person <a href="https://doi.org/10.1177/1534735420912835">can regain a sense of agency</a> and control.</p> <h2>How to bring creativity into daily life</h2> <p>For those new to exploring art as a creative pursuit or for well-being reasons, engaging in creative activities begins with letting go of unrealistic expectations. Being creative isn’t about becoming a famous artist or even a mediocre one. It is about allowing ourselves to flex the creative muscle that we all have and enjoying all the sensory and emotional aspects of imagining.</p> <p>Next, think about activities that made you feel free to explore when you were a child. Did you like singing, playing in the outdoors, dancing, making up pretend plays, or writing little tales? Allow yourself to indulge in any and all of these creative pursuits that made you feel relaxed and joyful.</p> <p>A <a href="https://doi.org/10.1016/j.aip.2021.101879">cultural tradition</a>, tinkering with electronics, making a gift for someone or simply paying attention to everyday beauty – any of these can be a creative activity. And just like any muscle, the more you exercise it, the stronger it becomes. Over time, you will notice yourself getting more confident and adventurous in your creative practices.</p> <p>Whatever it is, make time for this creative pursuit every week – which is possibly the hardest step of them all. If it seems “unimportant” compared with the demands of daily life, such as work or family, try thinking of it as another form of sustenance.</p> <p>Remember that creativity is just as critical to human health as <a href="https://theconversation.com/helping-children-eat-healthier-foods-may-begin-with-getting-parents-to-do-the-same-research-suggests-225157">eating nutritious meals</a> or <a href="https://theconversation.com/yoga-modern-research-shows-a-variety-of-benefits-to-both-body-and-mind-from-the-ancient-practice-197662">getting exercise</a> and <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">good rest</a>.

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

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

How would a switch to nuclear affect electricity prices for households and industry?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/roger-dargaville-1832">Roger Dargaville</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Peter Dutton has announced that under a Coalition government, seven nuclear power stations would be built around the country over the next 15 years.</p> <p>Experts have declared nuclear power would be <a href="https://www.abc.net.au/news/2024-06-20/power-prices-wont-fall-with-nuclear/103998172">expensive</a> and <a href="https://www.afr.com/politics/federal/nuclear-to-cost-17b-and-take-until-2040-to-build-csiro-20240521-p5jfaj#:%7E:text=Nuclear%20could%20cost%20up%20to,until%202040%20to%20build%3A%20CSIRO&amp;text=Peter%20Dutton's%20nuclear%20energy%20plans,operational%20until%20at%20least%202040.">slow to build</a>.</p> <p>But what might happen to energy prices if the Coalition were to win government and implement this plan?</p> <h2>How might we estimate the cost of nuclear?</h2> <p>By 2035, 50–60% of the existing coal-fired fleet will very likely <a href="https://aemo.com.au/-/media/files/stakeholder_consultation/consultations/nem-consultations/2023/draft-2024-isp-consultation/draft-2024-isp.pdf">have been retired</a>, including Vales Point B, Gladstone, Yallourn, Bayswater and Eraring – all of which will have passed 50 years old.</p> <p>These five generators contribute just over 10 gigawatts of capacity.

That said, we can make some broad assumptions based on a metric known as the “levelised cost of electricity”.</p> <p>This value takes into account:</p> <ul> <li> <p>how much it costs to build a particular technology</p> </li> <li> <p>how long it takes to build</p> </li> <li> <p>the cost to operate the plant</p> </li> <li> <p>its lifetime</p> </li> <li> <p>and very importantly, its capacity factor.</p> </li> </ul> <p>Capacity factor is how much electricity a technology produces in real life, compared with its theoretical maximum output.</p> <p>For example, a nuclear power station would likely run at 90–95% of its full capacity. A solar farm, on the other hand, will run at just 20–25% of its maximum, primarily because it’s night for half of the time, and cloudy some of the time.</p> <p>CSIRO recently published its <a href="https://www.csiro.au/en/research/technology-space/energy/gencost">GenCost</a> report, which outlines the current and projected build and operational costs for a range of energy technologies.</p> <p>It reports that large-scale nuclear generated electricity would cost between A$155 and $252 per megawatt-hour, falling to between $136 and $226 per megawatt-hour by 2040.</p> <p>The report bases these costs on recent projects in South Korea, but doesn’t consider some other cases where costs have blown out dramatically.</p> <p>The most obvious case is that of <a href="https://www.edf.fr/en/the-edf-group/dedicated-sections/journalists/all-press-releases/hinkley-point-c-update-1">Hinkley Point C nuclear plant</a> in the United Kingdom. This <a href="https://www.reuters.com/business/energy/edfs-nuclear-project-britain-pushed-back-2029-may-cost-up-34-bln-2024-01-23/">3.2GW</a> plant, which is being built by French company EDF, was recently <a href="https://www.edf.fr/en/the-edf-group/dedicated-sections/journalists/all-press-releases/hinkley-point-c-update-1">reported</a> to be now costing around £34 billion (about A$65 billion). That’s about A$20,000 per kilowatt.</p> <p>CSIRO’s GenCost report assumed a value of $8,655 per kilowatt for nuclear, so the true levelised cost of electricity of nuclear power in Australia may end up being twice as expensive as CSIRO has calculated.</p> <hr /> <p><iframe id="Aryx7" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/Aryx7/4/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <h2>Other factors play a role, too</h2> <p>Another factor not accounted for in the GenCost assumptions is that Australia does not have a nuclear industry. Virtually all the niche expertise would need to be imported.</p> <p>And very large infrastructure projects have a nasty habit of <a href="https://www.cis.org.au/publication/bungles-blowouts-and-boondoggles-why-australias-infrastructure-projects-cost-more-than-they-should/">blowing out in cost</a> – think of Snowy 2.0, Sydney’s light rail project, and the West Gate Tunnel in Victoria.</p> <p>Reasons include higher local wages, regulations and standards plus aversion from lenders to risk that increases cost of capital. These factors would not bode well for nuclear.</p> <p>In CSIRO’s GenCost report, the levelised cost of electricity produced from coal is $100–200 per megawatt-hour, and for gas it’s $120–160 per megawatt-hour. Solar and wind energy work out to be approximately $60 and $90 per megawatt-hour, respectively. But it’s not a fair comparison, as wind and solar are not “dispatchable” but are dependent on the availability of the resource.</p> <p>When you combine the cost of a mix of wind and solar energy and storage, along with the cost of getting the renewable energy into the grid, renewables end up costing $100–120 per megawatt-hour, similar to coal.</p> <p>If we were to have a nuclear-based system (supplemented by gas to meet the higher demands in the mornings and evenings), the costs would likely be much higher – potentially as much as three to four times if cost blowouts similar to Hinkley Point C were to occur (assuming costs were passed on to electricity consumers. Otherwise, taxpayers in general would bear the burden. Either way, it’s more or less the same people).</p> <h2>But what about the impact on your household energy bill?</h2> <p>Well, here the news is marginally better.</p> <p>Typical retail tariffs are 25-30 cents per kilowatt-hour, which is $250–300 per megawatt-hour. The largest component of your energy bill is not the cost of generation of the electricity; rather, it’s the cost of getting the power from the power stations to your home or business.</p> <p>In very approximate terms, this is made up of the market average costs of generation, transmission and distribution, as well as retailer margin and other minor costs.</p> <p>The transmission and distribution costs will not be significantly different under the nuclear scenario compared with the current system. And the additional transmission costs associated with the more distributed nature of renewables (meaning these renewable projects are all over the country) is included in the estimate.</p> <p>According to my back-of-the-envelope calculations, your retail tariff under the nuclear scenario could be 40–50c per kilowatt-hour.</p> <p>But if you are a large energy consumer such as an aluminium smelter, you pay considerably less per kilowatt-hour as you don’t incur the same network or retailer costs (but the cost of generating electricity in the first place makes up a much bigger proportion of the total cost).</p> <p>So if the cost of electricity generation soars, this hypothetical aluminium smelter’s energy costs will soar too.</p> <p>This would be a severe cost burden on Australian industry that has traditionally relied on cheap electricity (although it’s been a while since electricity could be described as cheap).</p> <h2>A likely increase in energy costs</h2> <p>In summary, in a free market, it is very unlikely nuclear could be competitive.</p> <p>But if a future Coalition government were to bring nuclear into the mix, energy costs for residential and especially industrial customers would very likely increase.<!-- Below is The Conversation's page counter tag.

Cafe providing free meals to families faces shutdown

<p>Kirsty Parkes spends a lot of her time providing food and clothes to those in need amid the cost-of-living crisis by running a community cafe. </p> <p>But now, her beloved cafe may close if she doesn't receive urgent financial help. </p> <p>"We need to pay our bills in order to keep this going and if we don't pay our bills, people don't eat," Parkes, who has a big family of her own, told <em>A Current Affair</em>. </p> <p>Community Cafe in Sydney's south-west became a safe haven for dozens of men, women and children, with over 100 people showing up every day. </p> <p>The cafe is a place where people can get food, clothes and toiletries for free, as well as connect with others. </p> <p>"We want to help people restore their value and restore their dignity," Parkes said.</p> <p>"Our currency is just a little bit different. So instead of using money, we use manners. Because manners and kindness are free."</p> <p>However, with an increase in costs and a lack of donations, the beloved cafe may soon be forced to close. </p> <p>"Whether there's a rate rise, whether there's a petrol hike, all of these little things affect us tremendously and affect the numbers here," she said.</p> <p>"We need to come up with some funds really desperately before then just to keep us open," she added. </p> <p>She said that at this stage they require "around about $20,000. Our electricity bill alone is almost $10,000."</p> <p>She added that  Cabravale Diggers, who have been paying the cafe's rent, and Liverpool City Council, who have also been providing financial assistance, can't continue to hold responsibility for all of the bills. </p> <p>"We've had fantastic sponsorship, we have fantastic people that back us ... but they can't carry the burden of this," Parkes said.</p> <p>"This is something that the whole community needs to get behind and support."</p> <p>The cafe provides invaluable support for customers like Ted and Lola, who find it hard to find a similar community. </p> <p>"I go to church. Not even a church will help me," Lola said.</p> <p>"These people - I don't even know them and out of nowhere they're taking rich and poor, whoever turns up."</p> <p>"It's hard living on a pension. It's very hard," Ted added. </p> <p>Parkes added that as things are starting to run out, she has had to impose rations, which has been difficult for her. </p> <p>"We've had to then turn around and say 'look today, sorry we can only give you two loaves of bread because we just don't have enough for everyone that's going to come through the door'," Parkes said.</p> <p>"That stuff breaks my heart. It absolutely kills me because people are hungry."</p> <p>From Friday, customers may have to be turned away.</p> <p>"It's terrible. How can we close? We see over 120 people a day. It's terrible," one of the volunteers at the community cafe said. </p> <p>"The community needs it. We can't close. We absolutely cannot close."</p> <p> Those who would like to help the cafe stay open have been encouraged to visit their <a href="https://www.facebook.com/Communitycafe.inc" target="_blank" rel="noopener">Facebook page</a>.</p> <p><em>Image: A Current Affair</em></p>

How to sign up for energy bill relief

<p>In the face of rising living costs, thousands of Australians have turned to their energy providers for financial assistance, highlighting the community spirit and support available during these challenging times. Energy companies like AGL Australia and Energy Australia are stepping up to help their customers manage their bills and find relief.</p> <p>AGL Australia has seen a significant increase in its financial hardship program, with 10,000 customers joining in the past year. Energy Australia receives 1,000 calls every weekday from customers seeking bill relief. These numbers reflect the proactive measures Australians are taking to manage their expenses and the readiness of energy providers to offer support.</p> <p>Crystal Noronha, who has worked at the AGL call centre for 11 years, has witnessed firsthand the growing need for assistance. "There's a lot of distress in their voice, there's anxiety," Noronha <a href="https://www.9news.com.au/national/thousands-of-customers-signing-up-for-energy-bill-relief-with-millions-more-eligible/9dc9535b-f94b-42f4-aeaf-6534dc898df2" target="_blank" rel="noopener">shared with 9NEWS</a>. "Some hide away from sharing their difficulties, but we're here to help them."</p> <p>Customers need not face extreme financial hardship to seek help, as everyone is eligible for some form of assistance.</p> <p>Gavin Dufty, from the charity St Vincent De Paul, underscores the commitment of energy companies to support their customers. "Every energy company has a legal obligation to provide support for all households regardless," Dufty explains. The assistance offered varies based on the provider and individual circumstances, ranging from bill extensions and more manageable payment plans to, in some cases, complete debt waivers.</p> <p>Adding to this support, the federal government is taking significant steps to ease the burden on households. Starting July 1, every household will receive a $300 credit into their energy account, providing substantial relief. Additionally, a free government website is available for customers to compare energy plan prices and find the most cost-effective options.</p> <p>These measures reflect a collaborative effort between energy providers and the government to ensure Australians can navigate the financial challenges of today's world. By offering practical solutions and financial relief, they are making a positive impact on the lives of many, ensuring that no one is left to face these difficulties alone.</p> <p><em>Image: Getty</em></p>

Your unique smell can provide clues about how healthy you are

<p><em><a href="https://theconversation.com/profiles/aoife-morrin-1478132">Aoife Morrin</a>, <a href="https://theconversation.com/institutions/dublin-city-university-1528">Dublin City University</a></em></p> <p>Hundreds of chemicals stream from our bodies into the air every second. These chemicals release into the air easily as they have high vapour pressures, meaning they boil and turn into gases at room temperature. They give clues about who we are, and how healthy we are.</p> <p>Since ancient Greek times, we’ve known that we smell differently when we are unwell. While we rely on blood analysis today, ancient Greek physicians used smell to diagnose maladies. If they took a whiff of your breath and described it as <em>fetor hepaticus</em> (meaning bad liver), it meant you could be headed for liver failure.</p> <p>If a person’s whiff was sweet or fruity, physicians thought this meant that sugars in the digestive system were not being broken down, and that person had probably diabetes. Science has since shown the ancient Greeks were right – liver failure and <a href="https://tisserandinstitute.org/human-volatilome/">diabetes</a> and many <a href="https://link.springer.com/article/10.1007/s00216-023-04986-z">other diseases</a> including infectious diseases give your breath a distinctive smell.</p> <p>In 1971, <a href="https://www.nobelprize.org/prizes/peace/1962/pauling/facts/">Nobel Laureate chemist Linus Pauling</a> <a href="https://edu.rsc.org/feature/breath-analysis/2020106.article#:%7E:text=The%20'modern%20era'%20of%20breath,in%20an%20average%20breath%20sample.">counted 250 different</a> gaseous chemicals in breath.

We have learned that many of these VOCs have distinctive odours, but some have no odour that our noses can perceive.</p> <p>Scientists believe that whether a VOC <a href="https://tisserandinstitute.org/human-volatilome/">has an odour</a> that our noses can detect or not, they can reveal information about how healthy someone is.</p> <p>A Scottish man’s Parkinson’s disease onset was <a href="https://www.bbc.co.uk/news/uk-scotland-47627179">identified by his wife</a>, retired nurse Joy Milner, after she was convinced the way he smelled had changed, years before he was diagnosed in 2005.

They are also emitted from skin, urine and faeces.</p> <p>VOCs from skin are the result of millions of skin glands removing metabolic waste from the body, as well as waste generated by bacteria and other microbes that live on our skin. Sweating produces extra nutrients for these bacteria to metabolise which can result in particularly odorous VOCs. Odour from sweat only makes up a fraction of the scents from VOCs though.</p> <p><a href="https://www.nature.com/articles/nrmicro.2017.157">Our skin</a> and also our gut microbiomes are made up from a delicate balance of these microbes. Scientists think <a href="https://journals.lww.com/co-gastroenterology/abstract/2015/01000/the_gut_microbiome_in_health_and_in_disease.12.aspx">they influence our health</a>, but we don’t yet understand a lot about how this relationship works.</p> <p>Unlike the gut, the skin is relatively easy to study – you can collect skin samples from living humans without having to go deep into the body. <a href="https://www-sciencedirect-com.dcu.idm.oclc.org/science/article/pii/S1471492221002087">Scientists think</a> skin VOCs can offer insights into how the microbiome’s bacteria and the human body work together to maintain our health and protect us from disease.</p> <p>In my team’s laboratory, <a href="https://iopscience.iop.org/article/10.1088/1752-7163/abf20a">we are investigating</a> whether the skin VOC signature can reveal different attributes of the person it belongs to. These signals in skin VOC signatures are probably how dogs distinguish between people by smell.</p> <p>We are at a relatively early stage in this research area but we have shown that you can tell males from females based on how acidic the VOCs from skin are. We use mass spectrometry to see this as the average human nose is not sophisticated enough to detect these VOCs.</p> <p>We can also predict a person’s age with reasonable accuracy to within a few years from their skin VOC profile. This is not surprising considering that oxidative stress in our bodies increases as we age.</p> <p><a href="https://www.metabolismjournal.com/article/S0026-0495(00)80077-3/pdf">Oxidative stress</a> happens when your antioxidant levels are low and causes irreversible damage to our cells and organs. <a href="https://pubs.acs.org/doi/10.1021/jasms.3c00315">Our recent research</a> found by-products of this oxidative damage in skin VOC profiles.</p> <p>Not only are these VOCs responsible for personal scent – they are used by plants, insects and animals as a communication channel. Plants are in a <a href="https://www.nature.com/articles/s41598-017-10975-x">constant VOC dialogue</a> with other organisms including pollinators, herbivores, other plants and their natural enemies such as harmful bacteria and insects. VOCs used for this back and forth dialogue are known as pheromones.</p> <h2>What has science shown about love pheromones?</h2> <p>In the animal kingdom, there is good evidence VOCs can act as aphrodisiacs. Mice for example have microbes which contribute to a particularly <a href="https://www.sciencedirect.com/science/article/pii/S0960982212012687">smelly compound called trimethylamine</a>, which allows mice to verify the species of a potential mate. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0093691X21003083">Pigs</a> and <a href="https://www.nature.com/articles/4381097a">elephants</a> have sex pheromones too.</p> <p>It is possible that humans also produce VOCs for attracting the perfect mate. Scientists have yet to fully decode skin – or other VOCs that are released from our bodies. But evidence for human love pheromones so far is <a href="https://www.science.org/content/article/do-human-pheromones-actually-exist">controversial at best</a>. <a href="https://www.newscientist.com/article/dn3835-colour-vision-ended-human-pheromone-use/">One theory suggests</a> that they were lost about 23 million years ago when primates developed full colour vision and started relying on their enhanced vision to choose a mate.</p> <p>However, we believe that whether human pheromones exist or not, skin VOCs can reveal who and how we are, in terms of things like ageing, nutrition and fitness, fertility and even stress levels. This signature probably contains markers we can use to monitor our health and diagnose disease.<!-- Below is The Conversation's page counter tag.

Lip reader provides evidence against Bruce Lehrmann

<p>A lip-reading expert has provided key evidence in Bruce Lehrmann's defamation trial against Network Ten, revealing what he believes was said between Lehrmann and Brittany Higgins on the night of the alleged rape. </p> <p>British lip reader Tim Reedy, a forensic lip reader who has previously worked for <em>The Sunday Times</em> to translate video of Royals speaking at funerals and weddings, has been grilled after deciphering what was said between the pair at a pub in Canberra. </p> <p>Reedy, who became profoundly deaf as a child, claimed that Bruce Lehrmann told Brittany Higgins that several drinks on a table on the night of her alleged rape were “all hers, all hers”.</p> <p>He explained he was “very certain that this is what was said” and the phrases were “more than 50 per cent” accurate.</p> <p>Mr Lehrmann’s barrister Steve Whybrow posed a series of questions over his claim that his client had said “Drink that all now”, and that Ms Higgins had said “I don’t want to”.</p> <p>“What I wanted to ask you, consistent with what you say in your appendix about how you go about lip reading, you took into account the context, which included your assessment that the man was plying her with drinks, is that correct?” Mr Whybrow asked.</p> <p>Reedy stood by his assessment, sharing that he  he had watched the video intently over a three-day period, saying he was able to use Apple technology to “fine tune” the images and had “the luxury” of going back and watching the footage repeatedly.</p> <p>At the conclusion of Mr Reedy’s evidence, Mr Lehrmann’s barrister Steve Whybrow argued it should not be admitted as evidence.</p> <p>Justice Lee disagreed with Mr Whybrow, saying: “I accept that lip reading is not perfect, but the guide for the admissibility of expert evidence is not a council of perfection. One has to take areas of specialised knowledge as one finds them.”</p> <p>“I do not think I should exclude the evidence. But the matters raised by Mr Whybrow are best seen through the prism of the ultimate weight to be given to the material. Accordingly I accept the tender of the material.”</p> <p>In the opening days of the trial, Network Ten barrister Matt Collins KC flagged flagged the lip reader's evidence, as he put to Mr Lehrmann some of the lip-reader's claims during cross examination.</p> <p>“You said to her ‘Drink that all now’, Dr Collins suggested.</p> <p>“I would just completely disagree with that,’’ Mr Lehrmann replied.</p> <p>“She responded, ‘I don’t want to’?” Collins asked.</p> <p>“I don’t recall that ever taking place, no,’’ Mr Lehrmann said.</p> <p>“You were encouraging Ms Higgins to get drunk,” Ten’s barrister Matthew Collins KC said during cross-examination.</p> <p>“No,” Lehrmann replied.</p> <p><em>Image credits: 7 Spotlight / Getty Images</em></p> <div class="media image side-by-side" style="caret-color: #000000; color: #000000; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; box-sizing: inherit; margin-bottom: 24px; display: flex; flex-direction: column; align-items: center; width: 705.202209px; max-width: 100%;"> </div>

<p>The future of Sam Newman's podcast is in jeopardy after his co-host Don Scott has officially quit the program. </p> <p>The shock exit comes after Newman launched into an expletive-ridden tirade at Scott last week in a now deleted segment of the podcast, which ended with Newman telling Scott to "f**k off" as he left the building. </p> <p>Now, Scott has returned to the You <em>Cannot Be Serious</em> podcast, but only to confirm he isn't coming back. </p> <p>“You do whatever you want to do … (but) what is the point of trying to have a discussion with somebody who is going off their brain?” Scott asked.</p> <p>“You do not talk to anybody no matter whether it is on-air or wherever in life when they are not rational, so you walk away."</p> <p>“I’m not getting into this … This is like a domestic and nobody wins in a domestic."</p> <p>“You can put your view as much as you like and I am not here to defend or whatever else."</p> <p>“Everybody has a different personality. I am not in to conflict.”</p> <p>Newman, who refused to believe he overreacted during the argument, asked, “Can we finally say that you’re not going to do the podcast anymore? Is that what’s going to happen?”</p> <p>Scott replied, “That’s fine at the moment, no.”</p> <p>Newman doubled down, saying, “This is history … This is breaking news. Don has now left the building, as Elvis has, and he’s not going to do the podcast anymore."</p> <p>“This is another show of disgraceful behaviour from someone who is acting like a child … it’s beyond belief.”</p> <p>Later on social media, Newman said that if Scott wasn't taking part in the podcast anymore, he wasn't sure how long they would continue with the show. </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/CyPXhh5vX0W/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/CyPXhh5vX0W/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by John ‘Sam’ Newman (@originalsmartassam)</a></p> </div> </blockquote> <p>“Won’t do it without Don, and even if he reconsiders, it will not be the same.

Calories and kilojoules: how do we know the energy content of food, and how accurate are the labels?

<p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a>, and <a href="https://theconversation.com/profiles/katelyn-barnes-1238606">Katelyn Barnes</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Everything we consume contains energy our bodies use to move, grow and maintain health. To work out how much energy is in different foods and drinks, we need to first look at a few core concepts.</p> <p>Firstly, you’ve probably heard of the units of measurement for energy – calories – as well as the metric equivalent, which is joules. One calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1℃.</p> <p>In human nutrition, the amounts of energy needed to maintain health, and to fuel a body, are much larger than the tiny singular calories used to heat up a gram of water. So, the term “calorie” in nutrition commonly refers to a <a href="https://www.sciencedirect.com/science/article/pii/S0022316622085546">kilocalorie</a> (or kcal), which is 1,000 calories. When you see the word “calories” on a nutrition label, it’s likely referring to kcals.</p> <p>The energy stored in food and drinks is released when the body breaks down one or more of the four macronutrients inside the food (carbohydrates, proteins, fats, alcohol). The body then uses that energy for activities such as keeping our heart beating, our lungs breathing and our muscles moving.</p> <p>When energy in food is estimated, it is the amount of energy food and drinks provide for these bodily processes. The four macronutrients provide <a href="https://www.sciencedirect.com/science/article/pii/S0002916522039454">different amounts of energy</a>:</p> <ol> <li>1 gram of carbohydrate provides about 4 kcal of energy</li> <li>1 gram of fat provides about 9 kcal of energy</li> <li>1 gram of protein provides about 4 kcal of energy</li> <li>1 gram of alcohol provides about 7 kcal of energy.</li> </ol> <h2>How are calories estimated?</h2> <p>There are two ways to estimate the amount of energy in food and drinks.</p> <p>The first is called “bomb calorimetry”. This gold-standard method involves placing a small sample of food or drink inside a device known as a bomb calorimeter. The food is burned in the presence of oxygen, releasing heat.</p> <p>The amount of heat released is directly related to the amount of energy in the food, allowing a calculation to be made. This method is most commonly used for foods rich in fats and is considered the most reliable (but expensive) method.</p> <p>The second method, the Atwater system, is a much less expensive method for estimating energy content. It is more commonly used when calculating energy of most food and drinks sold in supermarkets. Named after legendary food researcher <a href="https://www.sciencedirect.com/science/article/pii/S0022316622065336">Wilbur Atwater</a>, this system uses a standard conversion factor for each macronutrient found in food and drinks. By estimating the amount of each of the four macronutrients, an approximate calculation of the total energy can be made.</p> <p>However, this method requires detailed knowledge of the ingredients within composite foods (such as muesli bars or hamburgers) – which may reduce accuracy. There is also a margin of error to expect with the Atwater system, because it assumes each ingredient is always the same in composition.</p> <p>For example, a cup of oats grown in one part of the country won’t necessarily have the exact same nutritional content as another cup of oats grown elsewhere, due to climate and soil differences. So, this system is an estimation based on an average.</p> <p>Importantly, both methods estimate the amount of energy <em>in</em> food and drinks. But the actual energy our bodies extract from these foods and drinks can vary due to factors such as individual differences in digestion and absorption, as well as food processing and cooking methods.</p> <h2>Why do foods have calories written on them?</h2> <p>In Australia, it’s a <a href="https://www.foodstandards.gov.au/consumer/labelling/panels/Pages/default.aspx">legal requirement</a> for packaged food items to have a nutrition information panel that displays the number of kcal it contains.</p> <p>However, homemade food items sold at places like a fresh market may not be required to provide a nutrition information panel. This will depend on the type of food being sold and the scale of the business operation.</p> <p>Fresh foods such as fruit, vegetables and meat also don’t require a nutrition information panel. To find out the number of kcal in them, you can either run an experiment with a bomb calorimeter or look up an estimated value in an online nutrition database.</p> <p>Food composition databases such as <a href="https://www.calorieking.com/us/en/">CalorieKing</a> compile information about the energy and nutrient content of various foods. Dietitians and other health professionals often use these databases to estimate the energy content of foods to inform dietary recommendations.</p> <h2>Different international standards</h2> <p>Both kJ and kcal refer to energy – they are just two different units of measurements (such as how inches and centimetres are two different units for measuring length). Kilojoules (kJ) is part of the International System of Units (SI).</p> <p>Australia, New Zealand and some parts of Europe use kJ. The United States and the United Kingdom use kcal. To convert between calories and kilojoules you use the conversion factors:</p> <ul> <li>1 kcal = 4.184 kJ</li> <li>1 kJ = 0.24 kcal (about ¼).</li> </ul> <p>For example, if you have a packet of chips with an energy content of 200 kcal, you can convert it to kJ as follows: 200 kcal × 4.184 = 836.8 kJ.</p> <p>As for how many calories are acceptable to eat, the Australian Guidelines for Healthy Eating estimate the average adult requires about 7,000kJ or 1,670Kcal every day. However, differences in age, gender, size, health and physical activity will influence how much energy a person needs.</p> <p>To estimate your personal energy requirements, you can use this <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients-dietary-energy-calculator#results-energy">nutrients and dietary energy calculator</a>.<!-- Below is The Conversation's page counter tag.

Energy bill relief to benefit just one Aussie demographic

<p>Nearly half a million older Australians will receive hundreds of dollars in energy bill relief as the federal government looks to battle rising power prices.</p> <p>Social Services Minister Amanda Rishworth revealed that all Commonwealth seniors health card holders will be given up to $500 per household.</p> <p>The 490,000-plus recipients will include an extra 16,320 people granted access to the card after the federal government introduced higher income thresholds for eligibility in November 2022.</p> <p>The new income limits are $90,000 for singles and $144,000 (combined) for couples.</p> <p>The government claimed this would benefit 52,000 older people by 2026-27.</p> <p>Rishworth explained the energy relief would be available from July 2023.</p> <p>The Australian Energy Regulator (AER) released its final determination on May 25, with a revised price increase higher than the March draft that saw a 20 to 22 per cent rise.</p> <p>AER chair Clare Savage said it had been a “difficult decision” but high wholesale energy costs continued to hike up retail prices.</p> <p>“No one wants to see rising prices, and we recognise this is a difficult time, that’s why it’s important for consumers to shop around for a better deal,” she said.</p> <p>Following the AER’s announcement, Opposition Leader Peter Dutton appeared on <em>Today</em> and said Prime Minister Anthony Albanese had “lied” to Australians about energy prices.</p> <p>“Let’s be very clear about it, he promised on 97 occasions your bill would go down by $275,” he told <em>Today</em> host Karl Stefanovic.</p> <p>“I think the government’s completely underestimating how much families and small businesses are hurting at the moment.”</p> <p>The bill comes shortly after the Australian Energy Regulator revealed electric prices were set to increase by 25 per cent for about 600,000 customers across three states from July 1.</p> <p>The federal government’s latest budget committed to $3 billion in financial support for those struggling to pay their power bill.</p> <p><em>Image credit: Shutterstock</em></p>

“She wasn’t ready to die”: Son speaks after mum on life support dies during power outage

<p dir="ltr">A grieving son is calling for energy companies to do better after his mum, Gloria Shae, 80, who was on life support, died during a power outage in Dubbo.</p> <p dir="ltr">Gloria was found collapsed on the floor after her oxygen machine switched off during an unexpected blackout at around 5am on May 8.</p> <p dir="ltr">The great-grandmother was woken up out of a deep sleep and was later on found trying to reach for her bottled oxygen.</p> <p dir="ltr">Now, her son Brian Shae, has spoken up about the tragic incident and is calling for energy companies to do better.</p> <p dir="ltr">"She wasn't ready to die," Brian said.</p> <p dir="ltr">"She was full of life and energy, she had planned what she was doing the next day.</p> <p dir="ltr">He said that his mother was a registered life support customer with Origin Energy and Essential Energy.</p> <p dir="ltr">Neither Brian, who lives in the same property, nor Gloria were notified about the outage by their energy providers.</p> <p dir="ltr">"If there was some sort of automated system that sent out a text message, I could have been there in 30 seconds, in under a minute,” the grieving son said.</p> <p dir="ltr">"We could have assisted her, we could have got her oxygen bottles to her.</p> <p dir="ltr">"She does have oxygen bottles in the home but at night you rely on the oxygen generator."</p> <p dir="ltr">Although emergency services arrived about 15 minutes after Gloria was found, and they managed to restart her heart, Brian said that by then she was already brain dead.</p> <p dir="ltr">Gloria’s oxygen machine was rented and didn't come fitted with a back-up battery.</p> <p dir="ltr">Providers currently only need to give customers using life support four days' notice if there is a planned power outage, but in the case of a blackout there is nothing in place to contact their customers or the next of kin.</p> <p dir="ltr">Instead, they urge vulnerable customers to have a back-up battery or generator, to call triple-zero in an emergency, and to “have contingency plans in place”.</p> <p dir="ltr">“But how could an 80-year-old lady who has woken up out of a deep sleep (and) short of breath manage to go out (and) start a generator?” Brian asked.</p> <p dir="ltr">Health Minister Ryan Park described the death as a “terrible tragedy” and said that he has spoken with NSW Health. The Health Minister also encouraged energy companies to find better ways to support vulnerable customers.</p> <p dir="ltr">“If there’s anything that we could have done differently, we will look at that,” he added.</p> <p dir="ltr">An Essential Energy spokesperson has also commented and said that the team had personally contacted the family to extend their "deepest condolences".</p> <p><em>Images: 9News</em></p>

1 in 4 households struggle to pay power bills. Here are 5 ways to tackle hidden energy poverty

<p><a href="https://energyconsumersaustralia.com.au/news/how-increases-in-energy-prices-are-impacting-consumers#:%7E:text=Energy%2520affordability%2520is%2520not%2520just,in%2520the%2520past%252012%2520months.">One in four Australian households</a> are finding it hard to pay their gas and electricity bills. As winter looms, <a href="https://www.aer.gov.au/news-release/default-market-offer-2023%25E2%2580%259324-draft-determination">energy price rises</a> will make it even harder. Cold homes and disconnections resulting from energy poverty threaten people’s health and wellbeing.</p> <p><a href="https://www.acoss.org.au/wp-content/uploads/2023/03/ACOSS-cost-of-living-report2-March-2023_web_FINAL.pdf">Income support for welfare recipients</a> and retrofitting homes to make them more thermally efficient – by adding insulation, for example – can ease the burden. And when homes are not too cold or hot, <a href="https://theconversation.com/fuel-poverty-makes-you-sick-so-why-has-nothing-changed-since-i-was-a-child-living-in-a-cold-home-201787">people’s health benefits</a>. This in turn <a href="https://apo.org.au/node/319556">eases pressure on the public health system</a>.</p> <p>However, many people are missing out on assistance as programs often do not recognise their difficulties. Their energy vulnerability is hidden.</p> <h2>What forms does hidden energy poverty take?</h2> <p><a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">Our newly published study</a> has revealed six aspects of hidden energy vulnerability. These are:</p> <ol> <li> <p>underconsumption – households limit or turn off cooling, heating and/or lights to avoid disconnections</p> </li> <li> <p>incidental masking – other welfare support, such as rent relief, masks difficulties in paying energy bills</p> </li> <li> <p>some households disguise energy poverty by using public facilities such as showers or pooling money for bills between families</p> </li> <li> <p>some people conceal their hardship due to pride or fear of legal consequences, such as losing custody of children if food cannot be refrigerated because the power has been cut off</p> </li> <li> <p>poor understanding of energy efficiency and the health risks of cold or hot homes adds to the problem</p> </li> <li> <p>eligibility criteria for energy assistance programs may exclude some vulnerable households. For example, people with income just above the welfare threshold are missing out on energy concessions. Energy retailer hardship programs also ignore people who have voluntarily disconnected due to financial hardship.</p> </li> </ol> <h2>5 ways to help these households</h2> <p>Our studies suggest trusted intermediaries such as people working in health, energy and social services can play a vital role in identifying and supporting such households.</p> <p>First, energy efficiency and hardship initiatives may be <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/care-at-home-system-improvements">integrated into the My Aged Care in-home care system</a>. Energy poverty risk identification, response and referral could be built into the national service’s assessment form. This could leverage existing client screening processes.</p> <p>The system’s front-line staff could connect at-risk householders with energy counsellors. These counsellors could help people access better energy contracts, concessions, home retrofits and appliance upgrade programs.</p> <p>A new Commonwealth “energy supplement” could help pay for essential energy-related home modifications. This would help avoid My Aged Care funds being diverted from immediate healthcare needs.</p> <p>Second, general practitioners and other health professionals could help identify energy vulnerability among patients with medical conditions of concern. They could also provide letters of support emphasising renters’ health-based need for air conditioners or heaters.</p> <p>Third, energy providers could use household energy data to identify those that seem to be under-consuming or are often disconnected. They could also identify those that are not on “best offer” deals. They could be proactive in checking struggling householders’ eligibility for ongoing energy concessions and one-off debt relief grants offered by states and territories.</p> <p>Energy providers could also make it easier for social housing providers to ensure concessions for tenants renew automatically.</p> <p>Fourth, local councils could use their data to identify at-risk householders. They might include those with a disability parking permit, discounted council rates or in arrears, on the social housing waiting list, Meals on Wheels clients and social housing tenants. Maternal and child health nurses and home and community care workers making home visits could call attention to cold or hot homes.</p> <p>Councils could employ in-house energy counsellors to provide assistance and energy literacy training. Council home maintenance teams could develop bulk-buying, insulation and neighbourhood retrofit programs.</p> <p>Strategies to reduce vulnerability to energy poverty should be part of municipal public health and wellbeing plans. Under these strategies, net-zero-carbon funds set up by states and local councils to reduce emissions could finance targeted housing retrofits.</p> <p>We also suggest setting up a central helpline to improve access to energy assistance via local referrals.</p> <p>Fifth, residential energy-efficiency programs could become more person-centric. For example, we already have <a href="https://www.homescorecard.gov.au/">Residential Efficiency Scorecard</a> audits to assess the thermal quality of a home. These audits could also explore whether concessions and better energy deals are available to the household.</p> <h2>Building capacity at all levels</h2> <p><a href="https://cur.org.au/cms/wp-content/uploads/2021/08/tackling-hidden-energy-final.pdf">Capacity-building strategies</a> are needed at all levels – individual, community and government – to overcome the <a href="https://www.sciencedirect.com/science/article/pii/S2214629623000737">challenges</a> of reducing energy poverty. Current obstacles include the competing priorities of service providers, lack of time and resources, and <a href="https://www.sciencedirect.com/science/article/abs/pii/S2214629622003553">poor co-ordination between siloed</a> programs and services.</p> <p>Access to essential energy services should be part of state and local governments’ strategic health plans.

Regulatory reforms and ongoing funding are both needed to improve the availability of energy-efficient, affordable homes for tenants.</p> <p>Our suggested strategies start with improving the skills and knowledge of trusted intermediaries.

Using these front-line professionals to help identify and act on energy poverty offers a novel, cost-effective and targeted solution.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/1-in-4-households-struggle-to-pay-power-bills-here-are-5-ways-to-tackle-hidden-energy-poverty-204672" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

Aussies set for power bill relief just before Christmas

<p dir="ltr">The Albanese government has introduced a bill to help battling Aussies feel some relief during the ongoing cost of living crisis by bringing down the cost of unsustainable energy prices. </p> <p dir="ltr">Treasurer Jim Chalmers says Australians need “urgent, targeted, meaningful action” to take some of the sting out of the increasing power costs, which will be addressed through a new energy package to give households and small businesses some relief.</p> <p dir="ltr">MPs and senators were recalled to Canberra for a special session of parliament on Thursday to debate the government’s package, as it will now sail through both houses after Anthony Albanese secured the Senate support of the Greens, David Pocock, and the Jacqui Lambie Network. </p> <p dir="ltr">Opposition Leader Peter Dutton has confirmed the Coalition will not support the Bill, saying it would be “catastrophic” for Australian economic policy.</p> <p dir="ltr">Once passed, gas prices will be capped at $12 a gigajoule for 12 months, which the government says will slash power bills by about $230. </p> <p dir="ltr">The Queensland and NSW governments will also enforce a cap on coal for the same amount of time, at $125 a tonne.</p> <p dir="ltr">The package also includes $1.5 billion of additional relief to small businesses and some households.</p> <p dir="ltr">In introducing the Bill in the House on Thursday morning, Dr Chalmers said without urgent market intervention, retail gas prices were tipped to increase by a further 20 per cent and electricity prices by 36 per cent in the next financial year.</p> <p dir="ltr">“That’s why urgent action is needed … And when we vote today, every member of this place will make a choice,” he said. </p> <p dir="ltr">“To help Australians with rising energy bills – or to make it even harder for them.”</p> <p dir="ltr">“To save Australian jobs – or to surrender them. “</p> <p dir="ltr">“We choose to protect households and small businesses.

The first biography of Lachlan Murdoch provides some insights, but leaves important questions unanswered

<p>The title of Paddy Manning’s <a href="https://www.blackincbooks.com.au/books/successor" target="_blank" rel="noopener">The Successor: The High-Stakes Life of Lachlan Murdoch</a> tells us what is good and not so good about this biography.</p> <p>It is a smart play on the title of the much-applauded HBO television series, <a href="https://www.hbo.com/succession" target="_blank" rel="noopener">Succession</a>, which everyone except the show’s creators says is modelled on the decades-long corporate psychodrama within the Murdoch family. The Murdochs have said little about the Emmy Award-winning show, but in a knowing wink they chose to use Succession’s grandly jarring theme music in a tribute to Rupert at his 90th birthday party.</p> <p>I say “Rupert” because he has long since joined the small club of globally famous figures known by their first name. Not so Lachlan Murdoch, Rupert’s third child but, importantly for him, his eldest son.</p> <p>The book’s subtitle is the giveaway. If a “high-stakes life” was Lachlan Murdoch’s defining feature, would it need to be spelt out? The subtitle of a biography of, say, Don Bradman, does not need to inform us of his “high-stakes” life as a cricketer.</p> <p>Lachlan Murdoch turned 50 last year. He is executive chair and chief executive of Fox Corporation, co-chair of News Corporation, founder of the investment company Illyria Pty Limited, and executive chair of Nova Entertainment. He was in his mid-twenties when he first headed the Australian arm of News Limited, as it was then known. In recent years, after several twists and turns, he has become the anointed heir to Rupert’s global media empire. But he still sits deep in the shadow of his father.</p> <p>In June, the small independent news website Crikey published an <a href="https://www.crikey.com.au/2022/06/29/january-six-hearing-donald-trump-comfirmed-unhinged-traitor/" target="_blank" rel="noopener">opinion piece</a> arguing the Murdoch-owned Fox Corporation bore at least some responsibility for the January 6 riots at the Capitol in Washington. Many read it as referring to Rupert, but it was Lachlan who <a href="https://www.crikey.com.au/2022/08/24/crikey-statement-lachlan-murdoch/" target="_blank" rel="noopener">sued for defamation</a>.</p> <p>The ensuing commentary noted that Rupert has never sued a journalist for defamation and asked whether Lachlan is thin-skinned. It is a fair question, given Lachlan has sued a journalist before for inaccurately reporting his use of the company’s private jet.</p> <p>But it vaults over at least one reason Rupert has not sued: he has an army of his own journalists, who can be deployed to fight battles on his behalf. And they do. A relevant example is what happened to an authorised biographer, who slipped his minders and published a far less flattering portrait than had been anticipated.</p> <p>Rupert gave more than 50 hours of interviews to Michael Wolff and greenlit his access to key senior people in News Corporation, but the resulting biography, <a href="https://www.goodreads.com/book/show/4846256-the-man-who-owns-the-news" target="_blank" rel="noopener">The Man Who Owns the News: Inside the Secret World of Rupert Murdoch</a> (2008), reportedly infuriated Murdoch. It revealed, for instance, that the ageing media mogul was dyeing his hair to impress Wendi Deng, who is the same age as his second daughter, and who became his third wife in 1999.</p> <p>The biography was not mentioned in News Corporation’s US outlets until March 2009, when the Murdoch-owned tabloid the New York Post reported Wolff’s marital troubles in its <a href="https://pagesix.com/2009/03/30/bald-truth-divorce-for-wolff/" target="_blank" rel="noopener">Page Six gossip column</a>. “The bald, trout-pouted Vanity Fair writer, 55,” as Wolff was described, had been carrying on a “steamy public affair” with a 28-year-old intern, prompting his wife to evict him from their Manhattan apartment. So there.</p> <p>At least a half a dozen biographies have been written about Rupert, but The Successor is the first biography of Lachlan Murdoch. That alone makes it noteworthy. It is unauthorised and Lachlan was not interviewed for it, so it draws primarily on interviews with friends, colleagues and enemies, and on secondary sources, notably a good use of overseas media sources.</p> <p>It draws less heavily on the voluminous academic literature about the Murdoch media, though when it does, Yochai Benkler, Robert Faris and Hal Roberts’ book <a href="https://academic.oup.com/book/26406" target="_blank" rel="noopener">Network Propaganda</a> (2018) is quoted to good effect. Discussing the role of the Fox News television network, they write: “Conspiracy theories that germinate in the nether regions of the internet stay there unless they find an amplification vector”.</p> <p>What do we learn about the person who wields so much media power and influence? About Lachlan himself, not much. About Lachlan as a businessman, a bit more. About how Lachlan compares with Rupert and what that might mean for the media – and us, the audience – a good deal more.</p> <p>The portrait that emerges of Lachlan is drawn in bright colours – he has an adventurous spirit, tattoos, boyish good-looks; he is friendly and easygoing – but it does not have much depth. There are endless descriptions, in real-estate brochure mode, of overlong yachts and stylishly appointed bathrooms in multi-million dollar mansions dotted across the globe. And there are numerous gossipy accounts of parties with Tom and Nicole and Baz.</p> <p>Manning plumbs the standard biographical sources of his subject’s formative years, but they yield little of much import. At several points Joe Cross, a futures trader friend, is wheeled in to provide testimonials that are the verbal equivalent of eyewash. Here he is on Lachlan meeting his future wife, Sarah O’Hare:</p> <blockquote> <p>It was on […] he’s like, hook, line and sinker gone. And fair enough! With Sarah, she’s the whole package, she’s like a completely down-to-earth knockabout Aussie, being a supermodel didn’t hurt, and she loves all the things that Lachlan loved […] and she’s got a whole group of fabulous friends that now come together with his tight group of mates, and everyone gets on.</p> </blockquote> <p>More fruitfully, Manning recounts how Lachlan, for his final year thesis in an arts degree at Princeton, wrote about Immanuel Kant’s categorical imperative as inflected by the ideas in the Bhagavad Gita. The thesis was good, according to his supervisor, Professor Beatrice Longuenesse. But what stayed with her, as reported by a journalist who interviewed her many years later, was how Lachlan resembled many other graduates of elite universities, who “glide to the highest reaches of the business world, which they do not tend to disrupt with the lofty ideas they explored as undergraduates”.</p> <h2>Family business</h2> <p>Perhaps the most interesting insight is the extent to which Lachlan is conscious of his family and its history. The family business and the business of the family are pillars around which his life revolves, both by birthright and by choice. He remembers everything negative written about his father, and is fiercely protective of both him and the memory of his grandfather, Keith Murdoch, who for many years headed the Herald and Weekly Times.</p> <p>Surprisingly for an accomplished journalist, Manning tacitly accepts an abiding myth of the Murdoch family – Keith’s heroic role in writing the so-called “Gallipoli letter” during the first world war. Lachlan retold the story when his grandfather was inducted into the Melbourne Press Club’s Hall of Fame in 2012.</p> <p>That Sir Keith’s letter was, in important ways, misleading and sensationalised has been discussed by several journalists and authors, including Les Carlyon in his bestselling book <a href="https://www.panmacmillan.com.au/9781743534229/" target="_blank" rel="noopener">Gallipoli</a>, Mark Baker in his biography of another Gallipoli correspondent, <a href="https://insidestory.org.au/the-myth-of-keith-murdochs-gallipoli-letter/" target="_blank" rel="noopener">Phillip Schuler</a>, and by Tom Roberts in his award-winning 2015 <a href="https://theconversation.com/book-review-before-rupert-keith-murdoch-and-the-birth-of-a-dynasty-49491" target="_blank" rel="noopener">biography of Keith Murdoch</a>.</p> <p>Not that Lachlan has always deferred to his father. Manning recounts his subject’s fury when, in 1999, Rupert reneged on an agreement with his second wife Anna, Lachlan’s mother, who had “given up her claim to an equal share of Rupert’s fortune precisely to ensure that Prudence, Elisabeth, Lachlan and James would not have to share the control or assets of the Murdoch Family Trust with any children from Rupert’s marriage to Wendi Deng”.</p> <p>Manning’s biography shows it is not well known that Lachlan and Anna, whose marriage to Rupert lasted much longer than his other three wives, staved off an attempt by Rupert and Elisabeth to sack James after the News of the World phone-hacking scandal. The unfolding scandal overlapped with the period between 2005 and 2014 when Lachlan had left the family company, because his father had not backed him when he was being monstered by executives in the US arm of the business.</p> <p>Manning also recounts scenes from this period seemingly drafted for Succession. The then head of News Limited in Australia, John Hartigan, was forced to mediate between father and son over the amount of access Lachlan could have to the company’s Sydney headquarters. “Don’t let him into the fucking building,” Rupert is reported as saying. “When you’re out, you’re out.”</p> <p>Later, the Murdoch siblings began attending family counselling, where they discussed working together to “hold Rupert to account to be a mentor to James and not undermine him, as he had done with Lachlan so many years before”.</p> <h2>Failures and successes</h2> <p>Even Rupert Murdoch’s foes concede he has been a highly successful media businessman; what about Lachlan?</p> <p>He has had some searing failures. He led News’ role in the 1990s rugby league wars. With James Packer, he made a multi-million dollar losing investment in the internet service provider OneTel. Worst of all, he lost his $150 million investment in Channel Ten, which for a time he headed.</p> <p>He has also had some notable successes. He invested around $10 million early in a standalone online classified advertising site, realestate.com.au, that is today worth billions. He bought a share of an Indian Premier League cricket team, the Rajasthan Royals, whose value increased dramatically. And he bought into Nova Entertainment, successfully re-setting the pitch of its radio stations, notably Smooth FM.</p> <p>On the evidence presented in Manning’s biography, Lachlan is a good businessman, if not in the same league as his father, which is admittedly rarefied air. He was given a start in business few others have enjoyed. Sifting the benefits of privilege from natural ability and hard work is not straightforward, but Manning lays out a telling statistic. In 2022, Lachlan’s wealth was estimated at $3.95 billion in the Australian Financial Review’s annual rich list. The same list gave the wealth of his older sister Prudence at $2.58 billion. She “had not worked a day for their father’s business and had mostly escaped the Murdoch spotlight”.</p> <p>Prudence may well be a savvy investor, and her second husband worked for many years in News Corp. She may also have an eye to what happens to News and Fox in the future. The latest speculation among Murdoch watchers, which Manning discusses, is the possibility that after Rupert Murdoch’s passing, three of the four siblings who retain shares in the family company, Prudence, Elisabeth and James, will combine to oust Lachlan. According to one Wall Street analyst, who has followed News for decades and is privy to the breakdown in the relationship between the siblings, it is “fair to assume Lachlan gets fired the day Rupert dies”.</p> <h2>Right and wrong</h2> <p>It is hard to know whether this is real or just speculation. It is also not clear how much of the breakdown in family relationships is sibling rivalry and how much is fuelled by ideological differences. James Murdoch has severed ties with News and Fox. He is on the record criticising the company’s reporting on climate change and its coverage of former president Trump’s efforts to reject the electorate’s decision in the 2020 election.</p> <p>The core question The Successor raises in this reader’s mind, though, is how the portrait of Lachlan as a decent, socially progressive family guy in the first half of the book squares with the picture in the second half of a hard-nosed businessman who endorses the extreme, inflammatory opinions broadcast nightly on Fox News. Does he do this because it attracts viewers or because he actually believes Tucker Carlson’s ravings about the racist “great replacement” theory?</p> <p>Where does Lachlan stand on these issues? Like his father, he has an abiding love of newspapers, but appears most engaged with them as a business, where Rupert has always had an almost visceral sense of news, both for itself and for what it can do for him and his companies. Manning reports Lachlan’s speeches espousing the virtues of press freedom and his interviews defending Fox, but the speeches are boilerplate and the comments unconvincing. Asked in one interview about Fox’s role in polarising America, Lachlan pointed to criticism of Fox from the far right, saying: “If you’ve got the left and the right criticising you, you’re doing something right.”</p> <p>Or something profoundly wrong. This is the evidence of several media analyses reported in The Successor. Manning acknowledges that at a key point in the vote-counting for the 2020 presidential election, Fox News correctly called the result. But in the following two weeks the network cast doubt on the result at least 774 times, according to the watchdog group Media Matters.</p> <p>Media Matters is a left-leaning organisation, so its count might be dismissed as partisan, but an investigation earlier this year by the <a href="https://www.nytimes.com/2022/04/30/us/tucker-carlson-gop-republican-party.html" target="_blank" rel="noopener">New York Times</a> of 1100 episodes of Tucker Carlson Tonight found that he had amplified the great replacement theory 400 times. The number of guests who disagreed with Carlson was found to be decreasing, while the length of his monologues was increasing to double, even triple their earlier length.</p> <p>When the US congressional hearings into the January 6 riot at the Capitol were held earlier this year, Lachlan, according to Manning, decided to air them not on Fox News, but on the little watched Fox Business channel. This was in stark contrast not only to the prominence other television networks gave to the historic hearings, but to the vast amount of airtime previously given on Fox News to the</p> <blockquote> <p>wild and false claims of a rigged election by Rudy Guiliani and Sidney Powell […] once again calling into question whether the channel was really in the news business at all.</p> </blockquote> <p>Lachlan has argued that, however florid the opinions aired on Fox, the network’s news coverage is professional and balanced. Its coverage of the congressional hearings belied this claim. It was aired late at night, from 11pm. Apart from muted acknowledgement of the force of some of the testimony, Manning writes, “the rest was about sowing doubt and trying to move on”.</p> <p>By this point, most have realised that Lachlan is further to the right than his father, whose primary outlets in America, the Wall Street Journal and the New York Post, have denounced as shameful former president Trump’s role in the Capitol riot. The effect, then, of the second half of The Successor is to undermine the portrait of Lachlan in first half, rendering it almost meaningless. The two can’t be squared.</p> <p>Ultimately, Lachlan has to take responsibility for what Fox News does and the impact of its broadcasts. If he won’t, there are two multi-billion dollar lawsuits underway to focus his attention. The voting-machine companies, Smartmatic and Dominion, are alleging Fox News knowingly and maliciously spread a false narrative accusing them of election fraud.</p> <p>Lachlan is still young by the family’s standards. His grandmother, Dame Elisabeth Murdoch, died aged 103, which Rupert described, perhaps apocryphally, as an early death. As the first biography of the current head of a powerful media empire, The Successor is well worth reading. It probably won’t be the last biography; nor should it be, as there is more to know about Lachlan Murdoch, the enterprise he heads, and the siblings who appear to covet it.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/the-first-biography-of-lachlan-murdoch-provides-some-insights-but-leaves-important-questions-unanswered-192403" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Getty</em></p>

There’s also an updated National Security Bill currently before the House of Commons, which seeks to “create additional tools” to address security challenges like this one.</p> <p>By comparison, it’s unclear whether any ex-Australian Defence Force (ADF) personnel took up Chinese offers to train the PLA, or whether such an action would be considered a violation of the secrecy of information provisions of the Australian Criminal Code.</p> <p>Marles <a href="https://www.minister.defence.gov.au/transcripts/2022-11-09/press-conference-parliament-house" target="_blank" rel="noopener">explained</a> the Counter Foreign Interference Taskforce is “currently investigating a number of cases” identified by the department’s initial inquiries.</p> <p>This investigation will also seek to determine whether current policies and procedures are fit for purpose when it comes to former defence personnel and the protection of official secrets.</p> <p>Taking such measures has bipartisan support. Opposition Leader Peter Dutton <a href="https://www.skynews.com.au/australia-news/politics/peter-dutton-calls-on-albanese-government-to-tighten-up-laws-to-prevent-adf-personnel-spreading-australian-secrets/news-story/37ee6dc4c585922f7abf98edcc51b7b6" target="_blank" rel="noopener">has indicated</a> “if there is a hole in the legislation now, the Coalition will support a change which will tighten it up”. He added that Australia “can’t allow our secrets and our methodologies to be handed over to another country, and particularly not China under President Xi”.</p> <h2>Exposing our tactics</h2> <p>Dutton’s comments highlight an important distinction: while the training of PLA (or any foreign) pilots by ex-ADF personnel may not necessarily constitute a disclosure of official secrets, it still risks exposing the ways in which the ADF is trained to fight to a potential adversary – what are referred to as its tactics, techniques and procedures.</p> <p>There are many exchange personnel from overseas embedded in the ADF (and vice versa). But given the sensitivities involved, these positions are typically restricted to close partners such as the United States, United Kingdom, New Zealand or Canada. One of the benefits of close cooperation between militaries is that they can then operate more effectively alongside each other in the event of a conflict.</p> <p>But if ex-ADF personnel train the armed forces of potential adversaries, those opponents may be able to use this knowledge to better develop methods of their own to erode Australia’s military advantages.</p> <p>Professor <a href="https://twitter.com/alessionaval/status/1582232133086892032" target="_blank" rel="noopener">Alessio Patalano</a> of King’s College London points out that</p> <blockquote> <p>skilled personnel are valued capabilities and this know-how is a national security resource, and for the same reason a potential vulnerability.</p> </blockquote> <p>He further <a href="https://twitter.com/alessionaval/status/1582230651834548224" target="_blank" rel="noopener">explained</a> the “reverse engineering of professional skills” has a long historical tradition. That is, personnel undergoing this training would improve their skills, but could also work backwards from the instruction they receive to draw further insights into how the other state might operate in the event of war.</p> <p>For example, in the so-called “<a href="https://www.usni.org/magazines/naval-history-magazine/2019/december/jump-starting-japanese-naval-aviation" target="_blank" rel="noopener">Sempill Mission</a>” of British aviators to Japan in the 1920s, British personnel provided detailed instruction to their Japanese counterparts on how to conduct and train for aircraft carrier operations – at the time a brand new and rapidly emerging form of naval warfare. This training mission contributed significantly to the Imperial Japanese Navy’s prowess in aircraft carrier operations displayed in 1941.</p> <p>While foreign governments and intelligence services are always looking for opportunities to obtain classified information about Australia and its partners, the converse is also true.</p> <p>The Daily Express <a href="https://www.express.co.uk/news/world/1686465/RAF-news-china-uk-nato-raf-pilots-british-security-agencies" target="_blank" rel="noopener">claimed</a> British intelligence services used their knowledge of these recent activities as an opportunity for some pilots to obtain information on the current state of the PLA.</p> <p>The pilots allegedly had first-hand experience flying China’s frontline combat aircraft, and relayed the information to British authorities on their return.</p> <h2>Protecting our assets</h2> <p>Nevertheless, despite the “clear and unambiguous” obligation for former Commonwealth officials “to maintain [Australia’s] secrets”, ex-ADF personnel have been engaged in training foreign militaries for many years. In an interview with the ABC, former Secretary of Defence Dennis Richardson noted his <a href="https://www.abc.net.au/news/2022-11-09/ex-defence-secretary-dennis-richardson-adf-members-china/101635972" target="_blank" rel="noopener">surprise</a> “at some of the positions that some former ADF officers have occupied in other countries” and expressed his hope the government’s review “goes beyond China”.</p> <p>The most prominent of these figures is <a href="https://www.abc.net.au/news/2016-01-14/former-australian-soldiers-caught-up-in-yemen-civil-war/7087566" target="_blank" rel="noopener">Major General (Ret’d) Mike Hindmarsh</a>, a former Commander of Australia’s Special Operations Command who was subsequently appointed as the Commander of the United Arab Emirates’ Presidential Guard.</p> <p>Australia already has <a href="https://www.defence.gov.au/business-industry/export/controls/export-controls/export" target="_blank" rel="noopener">export control</a> regulations, which limits the physical export and intangible transfer of controlled military and dual-use goods and technologies. Also, stringent <a href="https://www.afr.com/work-and-careers/education/o-neil-alters-ministerial-sign-off-for-postgrad-students-20220630-p5axwq" target="_blank" rel="noopener">limitations</a> on international students undertaking postgraduate research in Australia on critical technologies were legislated in the last Parliament. However, these measures aren’t being currently being implemented until the government can more clearly define the relevant list of critical technologies.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/australia-is-investigating-whether-ex-defence-personnel-provided-military-training-to-china-would-it-matter-if-they-did-194252" target="_blank" rel="noopener">The Conversation</a>.</strong></p>
