Victoria Beckham's cooking skills hilariously slammed by her own daughter

<p>Victoria Beckham's cooking skills have been playfully roasted by her daughter, Harper Beckham.</p> <p>In an Instagram story shared to her 31.4 million followers, the former Spice Girl documented a family baking session featuring herself, husband David Beckham, and their daughter Harper.</p> <p>David was filmed in the middle of whipping up an apple crumble using apples from the "Beckham Orchard," while Harper was busy baking chocolate chip cookies.</p> <p>While the father-daughter duo were channeling their inner baker, Victoria was filming the moment and asked Harper whether she inherited her culinary talents from her mum or dad.</p> <p>"Did you learn to cook from daddy or mummy?" Victoria asked Harper in the light-hearted clip.</p> <p>With a mischievous grin, Harper retorted, "Mummy, you can't even make cereal!"</p> <p>"Oh wow, Mummy can't even make cereal," Victoria responded. </p> <p>"Well you can make chicken Kiev but that comes from M&amp;S," the 12-year-old said, adding insult to injury. </p> <p>M&amp;S (Marks and Spencer) is the local British retailer, which specialises in clothing, food and home products among other things. </p> <p>Victoria hilariously captioned the video: "I get it Harper… I can't cook."</p> <p>The Beckhams often invite fans into their kitchen through their social media, and document their cooking escapades. </p> <p>Watch the full clip <a href="https://kitchen.nine.com.au/latest/harper-beckham-roasts-mum-victoria-beckham-cooking-skills-in-new-clip/e538cdaa-f295-427d-b334-4bb7351da1bd" target="_blank" rel="noopener">here</a>. </p> <p><em>Images: Instagram</em></p>

Cooking (and heating) without gas: what are the impacts of shifting to all-electric homes?

<p><em><a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Gas connections for all new housing and sub-divisions will be <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">banned in Victoria</a> from January 1 next year. The long-term result of the state government’s significant change to planning approvals will be all-electric housing. The ACT made <a href="https://www.climatechoices.act.gov.au/policy-programs/preventing-new-gas-network-connections">similar changes</a> early this year, in line with a shift away from gas across <a href="https://www.bbc.com/news/science-environment-47559920">Europe</a> and <a href="https://www.theguardian.com/environment/2023/jan/19/gas-stove-culture-war-united-states">other locations</a>, although the NSW Premier Chris Minns has <a href="https://www.theguardian.com/australia-news/2023/jul/31/nsw-wont-ban-gas-in-new-homes-as-premier-declares-i-dont-need-another-complication">baulked</a> at doing the same.</p> <p>Around <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">80% of homes</a> in Victoria are connected to gas. This high uptake was driven by gas being seen as more affordable and sustainable than electricity over past decades. The situation has <a href="https://www.iea.org/events/net-zero-by-2050-a-roadmap-for-the-global-energy-system">changed dramatically</a> as renewable electricity generation increases and <a href="https://www.abc.net.au/news/2023-07-27/aemo-wholesale-electricity-prices-fall-impact-power-bills/102654498">costs fall</a>.</p> <p><a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">Research</a> has suggested for more than a decade that the benefits of all-electric homes <a href="https://bze.org.au/research_release/energy-efficient-buildings-plan/">stack up in many locations</a>. New homes built under mandatory building energy performance standards (increasing from <a href="https://thefifthestate.com.au/innovation/building-construction/victoria-kicks-the-can-down-the-road-again-on-the-national-construction-code/">6 to 7 stars</a> in Victoria in May 2024) need smaller, cheaper heating and cooling systems. Installing reverse-cycle air conditioning for cooling provides a cost-effective heater as a bonus.</p> <p>Savings from not requiring gas pipes, appliances and gas supply infrastructure help to offset the costs of highly efficient electric appliances. Mandating fully electric homes means economies of scale will further reduce costs.</p> <h2>How does this ban help?</h2> <p>To achieve environmentally sustainable development, reforms of planning policy and regulation <a href="https://theconversation.com/sustainable-cities-australias-building-and-planning-rules-stand-in-the-way-of-getting-there-84263">are essential</a> to convert innovation and best practice to mainstream practice. Planning policy is particularly important for apartment buildings and other housing that may be rented or have an owners’ corporation. Retrofits to improve energy efficiency can be difficult in these situations.</p> <p>Banning gas in new and renovated housing will <a href="https://grattan.edu.au/report/getting-off-gas/">cut greenhouse gas emissions</a>. It’s also <a href="https://theconversation.com/gas-cooking-is-associated-with-worsening-asthma-in-kids-but-proper-ventilation-helps-151591">healthier for households</a> and <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/research-reports/the-victorian-healthy-homes-program-research-findings">reduces healthcare costs</a> as well as <a href="https://grattan.edu.au/report/getting-off-gas/">energy bills and infrastructure costs</a>. The Victorian government suggests the change will save all-electric households <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">about $1,000 a year</a>. Houses with solar will be even better off.</p> <p>The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely.</p> <p>Some households will face extra costs for electric appliances and solar panels. The government’s announcement of <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">$10 million</a> for Residential Electrification Grants should help with some of these costs while the industry adjusts.</p> <p>There will be impacts and benefits for the local economy. Some jobs may be lost, particularly in the gas appliance and plumbing industry. The government has announced financial support to retrain people and they will still have essential roles in the existing housing sector.</p> <p>Many gas appliances are imported, including ovens, cooktops and instantaneous gas water heaters. Some components of efficient electric products, such as hot water storage tanks, are made locally. Local activities, including distribution, sales, design, installation and maintenance, comprise much of the overall cost.</p> <h2>Challenges of change must be managed</h2> <p>Sustainability benefits will depend on what <a href="https://grattan.edu.au/report/getting-off-gas/">happens with the energy network</a>. We need more renewable energy, energy storage and smarter management of electricity demand.</p> <p>The shift to all-electric homes may mean winter peak demand for heating increases. Energy market operators and governments will have to monitor demand changes carefully to avoid the reliability issues we already see in summer. However, improving energy efficiency, energy storage and demand management will help reduce this load (and household costs).</p> <p>While the benefits are clear for new homes, the changes may <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">increase gas costs and energy poverty</a> for residents of existing housing who don’t shift to efficient electric solutions. The government has reconfirmed financial rebates to help households switch from gas.</p> <p>In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition.</p> <p>Social acceptance of some electric appliances may also be an issue. For example, <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/heet-housing-energy-efficiency-transitions">our research</a> has found some households dislike the way heating from reverse cycle air conditioners feels. Others do not like cooking on induction cooktops.</p> <p>Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash.</p> <p>Some electric appliances are available overseas but not in Australia. Higher demand may increase the range of imports. For example, floor-mounted heat pumps can make heating feel similar to gas heating while still providing effective cooling.</p> <p>We should not assume electric appliances are all equal. To improve consumer protection, action is needed on weak standards and limited and inconsistent public information. For example, information on noise levels and efficiency under a range of weather conditions must be standardised.</p> <p>Moving housing away from gas is an <a href="https://link.springer.com/book/10.1007/978-981-99-2760-9">important step</a> in the transition to a zero-carbon economy and energy system. Careful management is needed to ensure this transition is effective, accepted and fair.</p> <p>Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities.

Too big, too heavy and too slow to change: road transport is way off track for net zero

<p><a href="https://theconversation.com/profiles/robin-smit-594126">Robin Smit</a>, <em><a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p>The need to cut the emissions driving climate change is urgent, but it’s proving hard to decarbonise road transport in Australia. Its share of the nation’s total greenhouse gas emissions <a href="https://ageis.climatechange.gov.au/">doubled</a> from 8% in 1990 to 16% in 2020. New vehicles sold in Australia have <a href="https://theconversation.com/we-thought-australian-cars-were-using-less-fuel-new-research-shows-we-were-wrong-122378">barely improved</a> average emissions performance for the last decade or so.</p> <p>The federal government <a href="https://www.dcceew.gov.au/climate-change/publications/australias-emissions-projections-2022">publishes</a> emission forecasts to 2035 – 15 years short of 2050, the net-zero target date. Our <a href="https://www.transport-e-research.com/_files/ugd/d0bd25_7a6920bdd9e8448385863a7c23ec9ecf.pdf">newly published study</a> forecasts road transport emissions through to 2050. The estimated reduction by 2050, 35–45% of pre-COVID levels in 2019, falls well short of what’s needed.</p> <p>Our findings highlight three obstacles to achieving net zero. These are: Australia’s delay in switching to electric vehicles; growing sales of large, heavy vehicles such as SUVs and utes; and uncertainties about hydrogen as a fuel, especially for freight transport. These findings point to policy actions that could get road transport much closer to net zero.</p> <h2>How was this worked out?</h2> <p>Emissions and energy use vary from vehicle to vehicle, so reliable forecasting requires a detailed breakdown of the on-road fleet. Our study <a href="https://www.transport-e-research.com/software">used</a> the Australian Fleet Model and the net zero vehicle emission model (n0vem).</p> <p>The study focused on so-called <a href="https://www.cummins.com/news/2022/05/26/well-wheel-emissions-simplified">well-to-wheel emissions</a> from fuel production, distribution and use while driving. These activities account for about 75–85% of vehicle emissions. (<a href="https://theconversation.com/how-climate-friendly-is-an-electric-car-it-all-comes-down-to-where-you-live-179003">Life-cycle assessment</a> estimates “cradle-to-grave” emissions, including vehicle manufacture and disposal.)</p> <p>Working with European Union colleagues, our emissions simulation drew on an updated <a href="https://www.transport-e-research.com/_files/ugd/d0bd25_7a6920bdd9e8448385863a7c23ec9ecf.pdf">EU scenario</a> (EU-27) showing the changes in the EU vehicle fleet needed to meet the latest (proposed) CO₂ targets. Our study assumed Australia will be ten years behind the EU across all vehicle classes.</p> <p>We further modified the scenario to properly reflect Australian conditions. For instance, the EU has a much higher proportion of plug-in hybrid vehicles than Australia, where buyers are now bypassing them for wholly electric vehicles.</p> <h2>Energy use is shifting, but too slowly</h2> <p>Using this modified scenario, the simulation produces a forecast fall in total wheel-to-wheel emissions from Australian transport from 104 billion tonnes (Mt) in 2018 to 55-65Mt in 2050. Within the range of this 35–45% reduction, the outcome depends largely on the balance of renewable and fossil-fuel energy used to produce hydrogen.</p> <p>The modelling nonetheless predicts a large shift in energy use in road transport in 2050, as 2019 was basically 100% fossil fuels.</p> <p>The on-road energy efficiency of battery electric vehicles is roughly twice that of fuel cell electric (hydrogen) vehicles and roughly three times that of fossil-fuelled vehicles of similar type.</p> <p>The modelling results make this clear. In 2050, battery electric vehicles account for about 70% of total travel, but 25% of on-road energy use and only about 10% of total emissions.</p> <p>In contrast, fossil-fuelled vehicles account for about 25% of total travel in 2050, 60% of energy use and 75-85% of emissions. That’s even allowing for expected efficiency improvements.</p> <p>This means the shift to a mostly electric fleet by 2050 plus the use of hydrogen is predicted to fall short of what’s needed to get to net zero. It will require aggressive new policies to increase the uptake of electric vehicles across all classes.</p> <h2>Lighter vehicles make a big difference</h2> <p>But that is not the whole story. One neglected issue is the growing proportion of <a href="https://theconversation.com/we-may-be-underestimating-just-how-bad-carbon-belching-suvs-are-for-the-climate-and-for-our-health-190743">big, heavy passenger vehicles</a> (SUVs, utes). This trend is very noticeable in Australia. The laws of physics mean heavier vehicles need much more energy and fuel per kilometre of driving, and so produce more emissions.</p> <p>Currently, a large diesel SUV typically emits a kilogram of CO₂ for every 3 kilometres of driving, compared to 15km for a light electric vehicle and 200 kilometres for an e-bike. An average electric vehicle currently emits 1kg of CO₂ every 7km.</p> <p>This distance is expected to be around 60km in 2050, when renewables power the electricity grid. A lightweight electric car will more than double the distance to 125km per kilogram of CO₂. Reducing vehicle weights and optimising energy efficiency in transport will be essential to meet emission targets.</p> <p>The study modelled the impacts of <a href="https://www.automotiveworld.com/special-reports/vehicle-lightweighting-2/">lightweighting</a> passenger vehicles while keeping buses and commercial vehicles the same. If Australians had driven only small cars in 2019 for personal use, total road transport emissions would have been about 15% lower.</p> <p>The reduction in emissions from simply shifting to smaller cars is <a href="https://www.dcceew.gov.au/climate-change/publications/national-greenhouse-accounts-2019/national-inventory-report-2019">similar to</a> emissions from domestic aviation and domestic shipping combined. Importantly, lightweighting cuts emissions for all kinds of vehicles.</p> <h2>The uncertainties about hydrogen</h2> <p>Fuel cell electric vehicles using hydrogen account for only a few percent of all travel, but most will likely be large trucks. As a result, in our scenarios, they use a little over 10% of total on-road energy and produce 5-20% of total emissions, depending on the energy source used for hydrogen production and distribution.</p> <p>The modified EU scenario includes a significant uptake of hydrogen vehicles by 2050. That’s by no means guaranteed.</p> <p>The uptake in Australia has been negligible to date. That’s due to costs (vehicle and fuel), the need for new hydrogen fuel infrastructure, less mature technology (compared to battery electric vehicles) and limited vehicle availability. <a href="https://theconversation.com/we-must-rapidly-decarbonise-transport-but-hydrogens-not-the-answer-166830">Unresolved aspects</a> of hydrogen in transport include lower energy efficiency, the <a href="https://theconversation.com/for-australia-to-lead-the-way-on-green-hydrogen-first-we-must-find-enough-water-196144">need for clean water</a>, uncertainty about leakage, fuel-cell durability and value for consumers.</p> <h2>How do we get back on track?</h2> <p>Our study suggests Australia is on track to miss the net-zero target for 2050 mainly because of the large proportions of fossil-fuelled vehicles and large and heavy passenger vehicles.</p> <p>These two aspects could become targets for new policies such as public information campaigns, tax incentives for small, light vehicles, bans on selling fossil fuel vehicles and programs to scrap them. Other options to cut emissions include measures to reduce travel demand, optimise freight logistics and shift travel to public transport, to name a few.</p> <p>The study confirms the scale of the challenge of decarbonising road transport. Australia will need “all hands on deck” – government, industry and consumers – to achieve net zero in 2050.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/208655/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/robin-smit-594126">Robin Smit</a>, Adjunct Associate Professor, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: </em><em>Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Is it true the faster you lose weight the quicker it comes back? Here’s what we know about slow and fast weight loss

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>When people decide it’s time to lose weight, they’re usually keen to see quick results. Maybe they have an event coming up or want relief from health problems and discomfort.</p> <p>But expert guidelines typically recommend slower weight loss for the treatment of obesity. This tallies with a a widely held opinion that fast weight loss is more quickly regained. Slow weight loss is generally perceived as better for your health and more sustainable. Many programs offering “the fastest way to lose weight” are considered fad diets that severely restrict calories or eliminate some foods.</p> <p>But does slow and steady really win the weight-loss race? Or is fast weight loss just as effective and safe?</p> <h2>What’s the difference between slow and fast weight loss?</h2> <p>Governing bodies typically <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/weight-loss-a-healthy-approach">recommend</a> a weight loss of 0.5 to 1 kilogram each week, which would be defined as slow weight loss.</p> <p>So <a href="https://medlineplus.gov/ency/patientinstructions/000885.htm#:%7E:text=Rapid%20weight%20loss%20diet%20is,a%20week%20over%20several%20weeks.">fast weight loss</a> – also termed “rapid weight loss” – is losing more than 1 kilo a week over several weeks.</p> <h2>What does the research say about fast weight loss?</h2> <p>There are several well-conducted studies examining differing approaches.</p> <p>One <a href="https://pubmed.ncbi.nlm.nih.gov/25459211/">study</a> of 200 people randomly assigned them to fast or slow weight loss – 12 weeks versus 36 weeks – aimed at a 15% reduction in weight.</p> <p>The fast weight loss group was put on a very low energy diet using meal replacements, including shakes, bars and soups, three times per day. The slow weight loss group was advised on the <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian Guide to Healthy Eating</a> with the goal to eat 500 calories less than they used for energy (creating a calorie deficit) each day. They also used one to two meal replacements daily.</p> <p>Some 50% of the slow weight loss group and 81% of the fast weight loss group achieved 12.5% or more weight loss during this time.</p> <p>After this initial phase, those who had lost 12.5% or more were then placed on a weight maintenance diet for approximately 2.75 years.</p> <p>By the three-year mark, 76% of those in the slow weight loss and the same percentage of those in the fast weight loss group had regained their lost weight.</p> <p>So, it didn’t matter if they had lost it slow or fast, they still regained the weight.</p> <p>However, another <a href="https://www.sciencedirect.com/science/article/pii/S2405844020308513#bib17">study</a> on 101 postmenopausal women found fast weight loss resulted in better outcomes than a slow weight loss group at the three-year mark.</p> <p>But there are other factors to consider, aside from weight loss, when it comes to the differing ways of losing weight – such as changes in body composition and bone mineral density.</p> <p>This is best highlighted by a large <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">meta-analysis</a>. These type of studies combine the results of all previous well-conducted studies on the topic.</p> <p>While this <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">analysis</a> found the magnitude of weight loss was similar for both approaches, slow weight loss resulted in better outcomes than fast weight loss with respect to metabolism or how many calories we burn at rest.</p> <p>There were no differences in the amount of fat-free mass or muscle mass lost between the slow and fast weight loss groups. But slow weight loss resulted in greater reductions in fat mass and therefore a better fat-to-muscle ratio.</p> <p>Slow weight loss also seems better for bone density, because rapid weight loss results in a <a href="https://www.sciencedirect.com/science/article/pii/S2405844020308513#bib17">twice as much bone loss</a> and puts a person at increased risk of brittle bones or osteoporosis.</p> <h2>What about other diet approaches?</h2> <p>Research shows it doesn’t matter what type of macronutrient diet you follow – moderate or high-protein diet, low or high-carbodyrate diet, low or high-fat diet. All diet approaches achieve similar <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa0804748">weight loss outcomes</a>.</p> <p>The same can be said for fashionable ways of cutting calories from the diet, such as intermittent fasting. <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">Research</a> has shown such diets don’t result in any better weight loss results than any of its predecessors. This is because our body is extremely good at <a href="https://theconversation.com/whats-the-weight-set-point-and-why-does-it-make-it-so-hard-to-keep-weight-off-195724">protecting against weight loss</a>.</p> <h2>When you want to lose weight consider …</h2> <p><strong>Your metabolism</strong> When you lose large amounts of weight, you resting metabolic rate – the energy you burn at rest – will lower. Keeping your resting metabolic rate high is essential for keeping the weight off. Unfortunately, once it slows down, your resting metabolic rate doesn’t recover to the level it was pre-dieting <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/oby.21538">even after you regain weight</a>.</p> <p>However, research has confirmed <a href="https://pubmed.ncbi.nlm.nih.gov/32576318/">slow weight loss</a> preserves your resting metabolic rate compared with rapid weight loss. As does a weight loss program <a href="https://www.sciencedirect.com/science/article/pii/S2161831323002867?via%3Dihub">that includes exercise</a> rather than one that focuses on diet alone.</p> <p><strong>Side effects</strong> While restrictive diets can achieve rapid results, studies suggest they can come with adverse effects. This includes a <a href="https://pubmed.ncbi.nlm.nih.gov/16350561/">higher risk of gallstones</a> and deficiencies that can result in poor immune function, fatigue and a <a href="https://pubmed.ncbi.nlm.nih.gov/32613096/">decrease in bone density</a>. Such restrictive diets can make it challenging to meet your nutritional needs.</p> <p><strong>Sustainability</strong> Many fast weight loss diets restrict or exclude foods required for long-term health. Carbohydrates are often banned, yet wholegrain carbohydrates are an essential source of nutrition, helping with weight loss and <a href="https://www.sciencedirect.com/science/article/pii/S0002822301001948">prevention of disease</a>. Including meal replacements as part of a restrictive diet is also not sustainable for long.</p> <h2>The bottom line?</h2> <p>Regardless of how you lose the weight, it’s very difficult to maintain losses.

5 negotiation tactics to grab crazy property deals in a slowing market

<p>Rising interest rates have started to put the handbrakes on Australia’s runaway property market, and that’s good news for homebuyers who are now in a far stronger position to negotiate on a property than they have been over the last few years.</p> <p>One of the most apparent advantages for buyers in the current market is the reduced levels of competition. Fewer buyers mean that prices aren’t being driven higher, and if you’re a good negotiator, it’s possible to swoop in and find yourself a bargain.</p> <p>If you’re new to negotiating for property or unsure where to start, here are five tactics that will help you achieve a strong result at the negotiating table.</p> <ol> <li><strong>Know the market</strong></li> </ol> <p>You can’t succeed in a negotiation if you don’t know the value of the asset that you’re trying to buy in the first place. That’s why any good negotiator will always start by doing their research. You need to know the market better than your competition and don’t get caught up in any hype or opinions from a sales agent.</p> <p>Start by finding what comparable properties are selling for in the market. Look for the last three months of sales around your property. The sales should be of similar property types, sizes, ages, and land components. Another good way to get an idea of the price is to speak with local agents in the area. When you have a fair market value, you then know your “walk away price,” and you won’t find yourself getting emotional and overbidding.</p> <ol start="2"> <li><strong>Understand the vendor’s motivations</strong></li> </ol> <p>In any negotiation, there is a saying that whoever needs the deal least will likely be the one that comes out on top. When looking at potential properties to buy, you can be the world’s best negotiator, but if the vendor doesn’t need to sell, they will likely either wait for their price or walk away.</p> <p>Whenever you start looking at a property, try to ascertain as much information about the vendor as possible. That will give you an understanding of how motivated they are to sell, which will then impact how much you initially want to offer.</p> <ol start="3"> <li><strong>Be the strong bidder, not the highest</strong></li> </ol> <p>In a property transaction, price is just one piece of the puzzle. When a vendor weighs up an offer on their property, they are interested in the price, but the terms can also play a big part.</p> <p>For example, if you’re a cash buyer who can settle quickly, that might be far more appealing to a vendor than a higher offer that needs three months to settle. Similarly, a larger deposit could give a vendor more certainty that the transaction will occur.</p> <p>As a buyer, getting your finances in place ahead of time and then tailoring your terms to suit the vendor might give you an edge in a negotiation even if you’re not the highest bidder. Ultimately, the vendor wants their problem solved, and your job is to find out what it is and then make a strong offer that addresses those immediate needs.</p> <p>If you are ever tempted to make an unconditional offer, be sure you’ve done extensive due diligence and can secure finance, as there could be significant costs if you have to back out of the deal.</p> <ol start="4"> <li><strong>Unique offers</strong></li> </ol> <p>A great way to make your offer seem stronger than it might actually be is to come in with an odd-numbered amount. An offer price of $596,200 instead of $590,000 or $600,000 reflects that you’ve taken the time to do your due diligence, making your offer stand out.</p> <p>Another approach is to make a written offer with a deadline. That way, you can speed up the negotiation process, and it might prevent the sales agent from pitting your bid against another buyer to drive up the price.</p> <ol start="5"> <li><strong>Know the property</strong></li> </ol> <p>It’s critical to clearly understand what you’re buying before entering any negotiation. While you might have done your comparable sales analysis and have an excellent overall picture of what similar properties are selling for, you still need to investigate this particular property.</p> <p>Several things can impact the property’s value, which can help you negotiate. For example, if an awkward tenant occupies the property, it will be less appealing to many homebuyers, which you can use to your advantage. There may also be issues with the property, such as problematic zoning, service locations, or even large trees that can alter its value.</p> <p>The most obvious factor to consider is the state of the property and whether it needs renovation or repairs. In the current market, homebuyers are less interested in buying a property that needs work due to the cost of materials and difficulty finding tradespeople. That will give you a strong starting point to negotiate around the price.</p> <p>While getting a great deal is essential, it’s crucial not to compromise on the property’s quality. Quality is more important than a bargain, and a property’s performance will ultimately determine its value.</p> <p>A slowing real estate market presents an opportunity for buyers to negotiate and secure a great property deal. By understanding the local market, paying attention to the vendor’s motivations, and putting forward intelligent offers, you can potentially grab an excellent property deal in a slowing market.</p> <p><strong><em>Rasti Vaibhav is the author of The Property Wealth Blueprint (RRP $39.95) and Founder of Get RARE Properties, a bespoke independent buyers' agency that has been helping hundreds of clients across Australia secure their financial freedom through property. </em></strong></p> <p><strong><em>For more information, visit <a href="https://getrare.com.au">https://getrare.com.au</a></em></strong></p> <p><em>Image credits: Getty Images</em></p>

Slowing down in old age may point to a more sinister concern

<p dir="ltr">It’s widely accepted that we tend to lose muscle strength and general mobility as we get older, which tends to make completing general tasks, and simply moving through the world, more difficult. </p> <p dir="ltr">While these aches and pains are a common symptom of getting older, new <a href="https://www.ecu.edu.au/schools/medical-and-health-sciences/our-staff/profiles/post-doctoral-research-fellows/dr-marc-sim">research</a> conducted by the Edith Cowan University (ECU) indicates this could also be a signal for another sinister health concern of ageing: late-life dementia.</p> <p dir="ltr">Research teams from ECU’s Nutrition &amp; Health Innovation Research Institute and Centre for Precision Health have investigated the link between muscle function and dementia, examining more than 1000 women with an average age of 75. </p> <p dir="ltr">In collaboration with the University of Western Australia, the team measured the women’s grip strength and the time it took for them to rise from a chair, walk three metres, turn around and sit back down — known as a timed-up-and-go (TUG) test.</p> <p dir="ltr">These tests were repeated after five years to monitor any loss of physical performance.</p> <p dir="ltr">Over the next 15 years, almost 17 per cent of women involved in the study were found to have had a dementia event, categorised as a dementia-related hospitalisation or death.</p> <p dir="ltr">The team found lower grip strength and slower TUG were significant risk factors for presenting with dementia, independent of genetic risk and lifestyle factors such as smoking, alcohol intake and physical activity levels.</p> <p dir="ltr">The women with the weakest grip strength were found to be more than twice as likely to have a late-life dementia event than the strongest individuals. </p> <p dir="ltr">A similar relationship emerged between TUG performance and dementia, with the slowest in their TUG test more than twice as likely to experience dementia than the quickest.</p> <p dir="ltr">Senior researcher Dr Marc Sim said grip strength may be a measure of brain health due to the overlapping nature of cognitive and motor decline.</p> <p dir="ltr">“Possibly due to a range of underlying similarities, grip strength may also present as a surrogate measure of cardiovascular disease, inflammation and frailty, which are known risk factors for dementia,” Dr Sim said.</p> <p dir="ltr">Dr Sim went on to say that the findings could help healthcare professionals to identify dementia risk in patients earlier.</p> <p dir="ltr">“Incorporating muscle function tests as part of dementia screening could be useful to identify high-risk individuals, who might then benefit from primary prevention programs aimed at preventing the onset of the condition such as a healthy diet and a physically active lifestyle.”</p> <p dir="ltr">“The exciting findings were that decline in these measures was associated with substantially higher risk, suggesting that if we can halt this decline, we may be able to prevent late-life dementias.”</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Cooking mistakes that are making your food unhealthy

<p style="font-weight: 400;"><strong>Boiling your veggies</strong></p> <p style="font-weight: 400;">A review published in the <em>International Journal of Gastronomy and Food Science</em> in 2016 showed that boiling vegetables resulted in a high loss of vitamin C and folate. One study found that broccoli, for example, lost about 33 per cent of its vitamin C. “Water-soluble vitamins leach out,” says Nishta Saxena, a registered dietitian. “If you’re not using the fluids in something like a soup, you’re missing out on nutrients.”</p> <p style="font-weight: 400;"><strong>Rinsing raw chicken</strong></p> <p style="font-weight: 400;">While your favourite old cookbooks likely tell you to rinse a chicken before roasting, this outdated advice is a safety hazard. Running poultry under the tap may remove some of the bacteria (including salmonella and campylobacter, which can cause diarrhoea, vomiting and fever), but it’s also likely to transfer it around your kitchen –as far as nearly one metre from the sink, according to research from Drexel University in Philadelphia. “Droplets can spread from your hands to counter­tops and even onto the floor, which can be a concern, especially if you have small children,” says Saxena. To stay safe, skip the rinse and wash your hands thoroughly after you’re finished prepping your bird.</p> <p style="font-weight: 400;"><strong>Removing skins from produce</strong></p> <p style="font-weight: 400;">Peeling your produce rids your food of an important layer of nutrients. “Significant amounts of vitamins, minerals and fibre are found in the skins,” says Liz Powell, a registered dietitian. Researchers at the University of Maine estimate that the skins of potatoes, for example, contain 10 to 12 times more antioxidants than the flesh. Peeling fruits and vegetables also strips away a dose of insoluble fibre, which is crucial for digestion and bowel function. Concern about herbicide or pesticide residue isn’t a good enough reason to forego the peelings, says Powell. Washing your fresh produce will remove some pesticide residues from the surface, she says. You can also opt for organic varieties of heavily sprayed produce, such as peaches.</p> <p style="font-weight: 400;"><strong>Blending everything</strong></p> <p style="font-weight: 400;">A smoothie is a smart way to sneak in some greens (and down your breakfast in a hurry), but liquid meals tend to be unbalanced. They’re often lacking in protein, healthy fat and complex carbohydrates. These components work together to keep us feeling full and satisfied, Powell says. “Without them, it’s not really a balanced meal.” Powell recommends adding a scoop of yoghurt or protein powder and part of an avocado or a spoonful of hemp hearts for protein and fat. To sneak in a complex carb, you can add some oats to the blender or have a piece of wholegrain toast on the side, she says.</p> <p style="font-weight: 400;"><strong>Overdressing salads</strong></p> <p style="font-weight: 400;">“Salads have this health halo – we think we can add anything to them and they’ll still be a nutritious choice, but it’s just not true,” says Saxena. “If you’re topping your bowl with dried cranberries, candied pecans and a sweet goat cheese, you’ve easily added 30 grams of sugar to your so-called healthy lunch.” Chopped, raw nuts and seeds are better options to beef up the flavour profile of your greens. Oil-based dressings also tend to be more nutritious than their creamy counterparts.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/home-tips/cooking-mistakes-that-are-making-your-food-unhealthy" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

8 air fryer cooking tips you need to know

<p><strong>Check your air fryer's temperature</strong></p> <p>Just like with ovens, temperatures may vary between air fryer models. Test your air fryer to see if it runs above or below the selected temperature setting. You’ll want your fryer nice and hot.</p> <p><strong>Know your air fryer's cooking times</strong></p> <p>Since air fryer temperatures vary, so do cook times. That’s why air fryer recipes have wider time ranges. So, to find your air fryer cooking times you’ll need to experiment. Start checking the food at the shortest time, and check back a little later if it’s not done.</p> <p><strong>Give it a shake (or a flip)</strong></p> <p>To help food crisp, always turn, rotate, or shake contents in air fryer basket (just like flipping French fries, fish fillets, or homemade chicken strips halfway through cooking in a traditional oven).</p> <p><strong>Cook food in a single layer for best results</strong></p> <p>Allow plenty of air circulation to get even cooking and crispy results. One exception where you can stack and pack foods is if you’re roasting veggie side dishes in the air fryer. For instance, you can load the basket with a 400 grams of Brussels sprouts and roast them at 180° for 12-15 minutes, stirring once.</p> <p><strong>Bake up a little treat</strong></p> <p>Yes, you can bake homemade cookies in the air fryer! All it takes is a few minutes and chilled dough on stand-by. Models differ in their “baking” functions, so test just one or two cookies at first. You may need to adjust the temperature or cooking time.</p> <p><strong>Seeing smoke? Here's what to do </strong></p> <p>First off, don’t panic. Simply unplug the air fryer and remove the food basket. Make sure no food is lodged in the heating coil. Return food to the air fryer and continue cooking. If smoke persists, there may be oil or residue on the heating element. Unplug the machine, cool, and then wipe the coil clean with a damp cloth, just like the heating coil on an electric stove. From now on, make sure to clean your air fryer regularly.</p> <p><strong>Use a thermometer when cooking meat</strong></p> <p>Because the food can brown nicely on the outside before reaching an appropriate temperature on the inside, checking the temp with a meat thermometer is an important step for safety. That goes for previously frozen foods and fresh ones.</p> <p><strong>It's a quick option when cooking for one or two </strong></p> <p>Any more than that, and you may have to cook in batches – so be sure to account for that in your timing.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/8-air-fryer-cooking-tips-you-need-to-know" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Historic Swedish sailing ship slow to give up its secrets

<div> <p>The Swedish ship Vasa was supposed to be a beacon of military might when it launched in 1628, but it sank after sailing just over a kilometre, killing roughly 30 people  in the process.</p> <p>Since its recovery in 1961, the ship, its contents and the people who perished with it have become a valuable insight into 17th-century Swedish life.</p> <p>Now, an international team of researchers has looked closer at one of the skeletons, referred to as G, and have confirmed that it’s female.</p> <p>“Through osteological analysis it has been possible to discover a great deal about these people, such as their age, height and medical history. Osteologists recently suspected that G could be female, on the basis of the pelvis. DNA analysis can reveal even more,” says Dr Fred Hocker, director of research at the Vasa Museum, Sweden.</p> <div><a href="https://cosmosmagazine.com/science/biology/shipwrecks-habitats-microbiomes/"> </a></div> <p>“It is very difficult to extract DNA from bone which has been on the bottom of the sea for 333 years, but not impossible”, says Professor Marie Allen, a forensic geneticist at Uppsala University in Sweden.</p> <p>“Already some years ago we had indications that skeleton G was not a man but a woman. Simply put, we found no Y-chromosomes in G’s genetic material. But we could not be certain and wanted to confirm the result.”</p> <p>They were able to do that with a technique developed by the US Department of Defense’s Armed Forces Medical Examiner System’s Armed Forces DNA Identification Laboratory (AFMES-AFDIL).</p> <p>“We took new samples from bones for which we had specific questions. AFMES-AFDIL has now analysed the samples, and we have been able to confirm that G was a woman, thanks to the new test,” says Allen.</p> <p>Allen, along with AFMES-AFDIL collaborator Dr Kimberly Andreaggi, is now investigating the DNA for more detail about G.</p> <p>“Today we can extract much more information from historic DNA than we could earlier and methods are being continuously refined. We can say if a person was predisposed to certain illnesses, or even very small details, such as if they had freckles and wet or dry ear wax,” says Allen.</p> <p>The Vasa Museum, meanwhile, is collecting information for a book about the people who died on the ship.</p> <p>“We want to come as close to these people as we can. We have known that there were women on board Vasa when it sank, and now we have received confirmation that they are among the remains,” says museum historian Dr Anna Maria Forssberg.</p> <p>“I am currently researching the wives of seamen, so for me this is especially exciting, since they are often forgotten even though they played an important role for the navy.”</p> </div> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/history/vasa-shipwreck-female/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian. </em></p> <p><em>Images: Getty</em></p> </div>

Chris Hemsworth to slow down in Hollywood:

<p>Chris Hemsworth has revealed he’s taking a break from acting following the news that he is at very high risk of developing Alzheimer’s disease later in life.</p> <p>While he may be slowing down, <em>Page Six </em>reported that the Aussie actor’s upcoming schedule is not quite so idle.</p> <p>Hemsworth has four projects in the works, including the return of his iconic <em>Thor</em> character in the highly anticipated <em>Avengers</em> sequel, and an untitled Hulk Hogan biopic. Although after those four projects, a source said, “he doesn’t plan to take on many roles because of [learning about his high risk for] Alzheimer’s.”</p> <p>Speaking to <em>Vanity Fair</em>, Hemsworth, 39, said he’s “not talking about retiring by any means,”</p> <p>The 39-year-old discovered he’s at high risk for Alzheimer’s while filming the National Geographic and Disney+ docuseries, <em>Limitless</em>.</p> <p>He told <em>Vanity Fair</em> about “the intensity [of] navigating” the test results and highlighted while it’s not a diagnosis, it’s a scary sign that the disease is more likely to develop in him than most other people.</p> <p>“Most of us, we like to avoid speaking about death,” he said. “Then to all of a sudden be told some big indicators are actually pointing to this as the route which is going to happen, the reality of it sinks in. Your own mortality.”</p> <p>He revealed learning that he’s “eight to 10 times more likely” to develop Alzheimer’s, “triggered something in me to want to take some time off.”</p> <p>“I’ve been completing the things I was already contracted to do,” he said, adding that he plans to “go home and … to have a good chunk of time off and just simplify.

No, you shouldn’t wash raw chicken before cooking it. So why do people still do it?

<p>Food safety authorities and regulators <a href="https://foodsafety.asn.au/topic/tips-poultry/">around</a> <a href="https://www.cdc.gov/foodsafety/chicken.html#:%7E:text=after%20handling%20chicken.-,Do%20not%20wash%20raw%20chicken.,that%20previously%20held%20raw%20chicken.">the</a> <a href="https://www.food.gov.uk/safety-hygiene/cleaning">world</a> <a href="https://www.mpi.govt.nz/food-safety-home/preparing-and-storing-food-safely-at-home/clean-cook-chill/#:%7E:text=Don't%20wash%20raw%20chicken,food%20poisoning%20from%20campylobacter%20bacteria.">recommend</a> you don’t wash raw poultry before cooking. </p> <p>That’s because washing chicken can splash dangerous bacteria around the kitchen. It’s best just to thoroughly cook the chicken without washing it, so it is safe to eat.</p> <p>Despite this, chicken-washing remains common. A <a href="https://www.safefood.qld.gov.au/newsroom/does-raw-chicken-need-rinsing/">survey</a> by Australia’s Food Safety Information Council showed almost half of Australian home cooks washed whole chickens before cooking. Dutch research found <a href="https://www.foodsafetynews.com/2022/05/dutch-survey-finds-a-quarter-of-people-wash-chicken-despite-expert-advice/">25%</a> of consumers washed their chicken often or almost always.</p> <p>So why do people do it – and what does the research say about the risks of chicken-washing?</p> <h2>Chicken meat and germs</h2> <p>Incorrect cooking temperatures and cross-contamination between different foods are two of the most important factors linked to foodborne illness. </p> <p>This is particularly relevant to poultry meat. Two leading causes of foodborne illness are the bacteria <a href="https://www.cdc.gov/campylobacter/index.html">Campylobacter</a> and <a href="https://www.cdc.gov/foodsafety/communication/salmonella-food.html">Salmonella</a>, which are commonly found on raw poultry. </p> <p>In Australia, reported cases of Campylobacter and Salmonella have almost <a href="https://foodsafety.asn.au/topic/tips-poultry/">doubled</a>over the last two decades. </p> <p>Of the estimated 220,000 cases of Campylobacter infection each year, <a href="https://foodsafety.asn.au/topic/tips-poultry/">50,000</a> can be attributed either directly or indirectly to chicken meat.</p> <h2>Chicken-washing myths, busted</h2> <p>One <a href="https://doi.org/10.1016/j.foodcont.2020.107682">analysis</a> of consumer responses to an education campaign about the dangers of washing raw poultry shed light on why many people still wash raw chicken before cooking.</p> <p>Some believe there is a need to wash faeces and other matter off the chicken meat. In fact, modern processing techniques mean chicken carcasses do not need additional cleaning. </p> <p>Others believe washing with a slightly acidic solution (such as vinegar or lemon juice) will kill bacteria. </p> <p>On the contrary, <a href="https://doi.org/10.1016/j.foodcont.2018.06.034">research</a> has shown washing raw poultry in lemon juice or vinegar does not remove bacteria and can increase the cross-contamination risk.</p> <h2>Washing chicken splashes bacteria around</h2> <p>One of the more compelling arguments why washing raw poultry under a running tap is a risky activity comes from <a href="https://doi.org/10.1063/5.0083979">recent research</a> on water droplets ejected from the surface of washed chicken. </p> <p>The study clearly showed bacteria can be transferred from the surface of the chicken to surrounding surfaces via water droplets.</p> <p>Using high-speed imaging, the researchers found a higher tap height can increase splashing. </p> <p>Chicken meat is often soft and the water flow can create a divot in the surface. This leads to splashing that would not occur on a curved, hard surface. </p> <p>The researchers placed large agar plates next to the chicken surfaces to capture any water droplets. This allowed them to grow the bacteria that were transferred with the splashed water. </p> <p>They found the level of bacterial transmission increased with greater tap height and water flow rate. </p> <p>Aerated water (which is what you get when the tap is running very hard) also increased splashing and bacterial transmission. </p> <h2>What if I still really want to wash my chicken meat?</h2> <p>While washing raw poultry is not recommended, it appears some home cooks are reluctant to let go of this old habit. </p> <p>If you insist on washing chicken meat, consider doing so in a sink of water rather than under a running tap.</p> <p>Use a paper towel to mop up any liquids, dispose of the towel and clean up afterwards. </p> <p>This will help reduce the risk of cross-contamination and keep the kitchen safe. And please wash your hands after handling raw meat!</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/no-you-shouldnt-wash-raw-chicken-before-cooking-it-so-why-do-people-still-do-it-192723" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Are our phones really designed to slow down over time? Experts look at the evidence

<p>It’s usually around this time of year you hear people complain about their phones slowing down. Apple and Google release new versions of their operating systems (OS) and suddenly there’s a slew of people <a href="https://www.bbc.com/news/technology-51413724">claiming their old devices have started to lag</a> – conveniently just before Christmas. </p> <p>But do manufacturers really slow down our phones on purpose to nudge us towards shiny new ones, <a href="https://www.npr.org/2020/11/18/936268845/apple-agrees-to-pay-113-million-to-settle-batterygate-case-over-iphone-slowdowns">as has been claimed</a>? </p> <p>The answer to this, as usual, is complicated. Let’s take a look at the evidence.</p> <h2>The ol’ operating system shuffle</h2> <p>Every year, usually around <a href="https://infonewt.com/apple-release-patterns">May and June</a>, tech companies announce their new OS updates. The main news surrounding the releases is often <a href="https://www.macstories.net/stories/ios-and-ipados-15-the-macstories-overview/">new system features</a>such as <a href="https://support.apple.com/en-au/HT204380">Facetime</a> enhancements, improvements to <a href="https://www.theverge.com/2021/6/7/22522993/apple-siri-on-device-speech-recognition-no-internet-wwdc">voice assistants</a>, or a <a href="https://www.wired.com/2013/06/ios7-redesign/">fancier system design</a>.</p> <p>But did you know these features are optimised for the new hardware traditionally released during the summer, and the chips that come with it? </p> <p>As such, system updates have to be programmed to work towards two goals. The first is to support the new hardware and chip, which deliver the newest features. </p> <p>The second is to continue to work with existing hardware that won’t support the new features. And this means coding the OS so it’s not reliant on the new features having to work.</p> <p>This challenge exists for desktop OSs as well, as evidenced by the recent removal of old systems <a href="https://www.theverge.com/2021/6/29/22555371/microsoft-windows-11-cpu-support-hardware-requirements-tpm-response">from the Windows 11 compatibility list</a>. Microsoft decided coding around new features was an insurmountable challenge in some instances. </p> <h2>Hardships with hardware</h2> <p>So your old smartphone won’t support new features – fair enough. But why does it feel like the new OS update is making existing features slower? To understand this, you need to first understand some of the mechanics of chip design.</p> <p>Apple used to use other manufacturers’ chips for its devices, but for the past few years has made its own custom silicon. This is referred to as a “<a href="https://anysilicon.com/what-is-a-system-on-chip-soc/">system on a chip (SoC)</a>, as the entire system exists on a single chip designed and manufactured by Apple.</p> <p>But even if manufacturers design their own chips, it can be hard to predict what consumers will want in the future, and thus which upgrades will come with future iterations of a device. </p> <p>Manufacturers have to write OS updates to suit the latest hardware, so consumers who purchase it can take advantage of the latest features. In doing so, they must work around the fact that older hardware doesn’t have the same capacity. </p> <p>These workarounds mean older devices will run more slowly with the new OS installed, even for tasks the system had done for years. The latest OS is not written to make your old device slower, but because it’s written for the latest device, it can’t help but run more slowly on old hardware. </p> <p>Examples of this abound in the industry, <a href="https://arstechnica.com/gadgets/2020/09/ios-14-on-the-iphone-6s-and-se-performance-is-fine-other-stuff-is-not/">with many articles written</a> about a newly released OS version running slow on older devices until the manufacturer optimises it (if they ever do).</p> <p>You might be wondering: if a new OS will slow down old phones, why install the update at all? </p> <p>Well, it’s because people don’t like being told to stick with old features. Apple <a href="https://9to5mac.com/2021/06/07/apple-will-let-users-stay-on-ios-14-and-receive-security-updates-even-after-ios-15-is-released/">recently allowed</a> users of its latest devices to keep the old system, but this is unusual. There is usually a <a href="https://www.popsci.com/update-every-gadget/">push for users to install new OS versions</a>.</p> <h2>It’s all business</h2> <p>The truth is device manufacturers are in the business to make money. And this means being able to sell new devices. </p> <p>While there is often an <a href="https://theconversation.com/upgrade-rage-why-you-may-have-to-buy-a-new-device-whether-you-want-to-or-not-153105">implied expectation</a> from consumers that manufacturers will commit to maintaining old products, at the same time they need to write updates that will work for their latest hardware. </p> <p>Meanwhile, tech companies aren’t doing enough to educate users on how to adjust their settings to get the best out of their phones, or <a href="https://www.wired.com/story/remove-bloatware-phone/">how to manage software bloat</a> which might contribute to a phone slowing down. </p> <p>Compounding this are other factors such as network connection issues, like when the 3G mobile network was stopped.</p> <h2>Burden of proof</h2> <p>There’s something else to consider, too. If an OS update was designed to intentionally slow down a phone over time, this would be very difficult to prove. </p> <p>The system codes are "closed source”, so experts can’t look into them. The best we can do is run timers on different processes and see if they are slowing down over time.</p> <p>But even if they are, is it because of a system update that can’t be supported by old hardware, or is it malicious conduct from the manufacturer? Could the code be written to force the device to sleep for half a second, every ten seconds, with a sleep command? </p> <p>It’s hard to say for sure, although our personal opinion is this is highly unlikely.</p> <h2>Choose not to play</h2> <p>Ultimately, the issue comes down to how device manufacturers sell their products. </p> <p>The best option for their bottom line is to deliver OS updates and features that work with the latest hardware, even if this leaves old devices behind. The evidence suggests manufacturers are not intentionally slowing phones down, but are prioritising the latest release so you’ll buy it. </p> <p>In the meantime, if your slow device is getting you down, the best option is to resist the urge to upgrade. You might get prompts directing you to install the latest OS version (and the frequency of these will depend on the company) but you can ignore them. </p> <p>There may be auto-updates which you can’t avoid, but in most cases these are for security purposes and don’t include major changes or new features. It’s only once these security updates stop coming that you should upgrade.</p> <p>Until then, a phone running on its original OS should, in theory, run well for a long time.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/are-our-phones-really-designed-to-slow-down-over-time-experts-look-at-the-evidence-170962" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Do you use predictive text? Chances are it’s not saving you time – and could even be slowing you down

<p>Typing is one of the most common things we do on our mobile phones. A recent survey suggests that millenials spend <a href="https://www.provisionliving.com/blog/smartphone-screen-time-baby-boomers-and-millennials/">48 minutes</a> each day texting, while boomers spend 30 minutes.</p> <p>Since the advent of mobile phones, the way we text has changed. We’ve seen the introduction of autocorrect, which corrects errors as we type, and word prediction (often called predictive text), which predicts the next word we want to type and allows us to select it above the keyboard.</p> <p>Functions such as autocorrect and predictive text are designed to make typing faster and more efficient. But research shows this isn’t necessarily true of predictive text.</p> <p>A <a href="https://dl.acm.org/doi/10.1145/2858036.2858305">study</a> published in 2016 found predictive text wasn’t associated with any overall improvement in typing speed. But this study only had 17 participants – and all used the same type of mobile device.</p> <p>In 2019, my colleagues and I published <a href="https://doi.org/10.1145/3338286.3340120">a study</a> in which we looked at mobile typing data from more than 37,000 volunteers, all using their own mobile phones. Participants were asked to copy sentences as quickly and accurately as possible.</p> <p>Participants who used predictive text typed an average of 33 words per minute. This was slower than those who didn’t use an intelligent text entry method (35 words per minute) and significantly slower than participants who used autocorrect (43 words per minute).</p> <h2>Breaking it down</h2> <p>It’s interesting to consider the poor correlation between predictive text and typing performance. The idea seems to make sense: if the system can predict your intended word before you type it, this should save you time. </p> <p>In my most <a href="https://doi.org/10.1145/3411764.3445566">recent study</a> on this topic, a colleague and I explored the conditions that determine whether predictive text is effective. We combined some of these conditions, or parameters, to simulate a large number of different scenarios and therefore determine when predictive text is effective – and when it’s not.</p> <p>We built a couple of fundamental parameters associated with predictive text performance into our simulation. The first is the average time it takes a user to hit a key on the keyboard (essentially a measure of their typing speed). We estimated this at 0.26 seconds, based on <a href="https://dl.acm.org/doi/10.1145/2470654.2466180">earlier research</a>.</p> <p>The second fundamental parameter is the average time it takes a user to look at a predictive text suggestion and select it. We fixed this at 0.45 seconds, again based on <a href="https://dl.acm.org/doi/10.1145/1240624.1240723">existing data</a>.</p> <p>Beyond these, there’s a set of parameters which are less clear. These reflect the way the user engages with predictive text – or their strategies, if you like. In our research, we looked at how different approaches to two of these strategies influence the usefulness of predictive text.</p> <p>The first is minimum word length. This means the user will tend to only look at predictions for words beyond a certain length. You might only look at predictions if you’re typing longer words, beyond, say, six letters – because these words require more effort to spell and type out. The horizontal axis in the visualisation below shows the effect of varying the minimum length of a word before the user seeks a word prediction, from two letters to ten.</p> <p>The second strategy, “type-then-look”, governs how many letters the user will type before looking at word predictions. You might only look at the suggestions after typing the first three letters of a word, for example. The intuition here is that the more letters you type, the more likely the prediction will be correct. The vertical axis shows the effect of the user varying the type-then-look strategy from looking at word predictions even before typing (zero) to looking at predictions after one letter, two letters, and so on.</p> <p>A final latent strategy, perseverance, captures how long the user will type and check word predictions for before giving up and just typing out the word in full. While it would have been insightful to see how variation in perseverance affects the speed of typing with predictive text, even with a computer model, there were limitations to the amount of changeable data points we could include.</p> <p>So we fixed perseverance at five, meaning if there are no suitable suggestions after the user has typed five letters, they will complete the word without consulting predictive text further. Although we don’t have data on the average perseverance, this seems like a reasonable estimate.</p> <h2>What did we find?</h2> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/12/graph-text.jpg" alt="" />Above the dashed line there’s an increase in net entry rate while below it, predictive text slows the user down. The deep red shows when predictive text is most effective; an improvement of two words per minute compared to not using predictive text. The blue is when it’s least effective. Under certain conditions in our simulation, predictive text could slow a user down by as much as eight words per minute. </p> <p>The blue circle shows the optimal operating point, where you get the best results from predictive text. This occurs when word predictions are only sought for words with at least six letters and the user looks at a word prediction after typing three letters.</p> <p>So, for the average user, predictive text is unlikely to improve performance. And even when it does, it doesn’t seem to save much time. The potential gain of a couple of words per minute is much smaller than the potential time lost.</p> <p>It would be interesting to study long-term predictive text use and look at users’ strategies to verify that our assumptions from the model hold in practice. But our simulation reinforces the findings of previous human research: predictive text probably isn’t saving you time – and could be slowing you down.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/do-you-use-predictive-text-chances-are-its-not-saving-you-time-and-could-even-be-slowing-you-down-170163" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Does cooking bacon in water make it taste better

<p>A rumour on the internet has suggested the key to juicier, crispier bacon is submerging it in cold water and bringing it to the boil. But does this theory have legs?</p> <p>Well, the idea at least seems to check out. The difference between “good” and “bad” bacon generally comes down to the rendering of the fat from cooking to too long or too quickly. But when you cook it with the cold-water method, bringing the cold water to the simmer, cooking it away completely, you theoretically cook the fat away without drying the bacon, and once the water’s gone all you have to do is brown the meat.</p> <p><iframe width="560" height="315" src="https://www.youtube.com/embed/2guC4Badq2s" frameborder="0" allowfullscreen=""></iframe></p> <p><a href="http://www.news.com.au/lifestyle/food/eat/internet-cooking-test-should-you-cook-bacon-in-water/news-story/a4ac7d3e60033861c0a625ef9638c526" target="_blank"><span style="text-decoration: underline;"><em><strong>News.com.au</strong></em></span></a> recently put this to test, cooking a control and putting it up against the new bacon cooking method, “The ‘new’ method had produced much drier, darker bacon. It was crispier as promised, but in a way that made it less enjoyable to eat. It had developed the consistency reminiscent of beef jerky.</p> <p>“Even worse, this method seemed to have leached a lot of the bacon’s salt content out into the water before gluing it back to the outside of the bacon as it evaporated, making the bacon much saltier to taste.”</p> <p>So, what do you think? Are you going to experiment with this new bacon-cooking method, or stick to what you know works? Let us know in the comments below. </p>

"Dramatic result": New drug shows hope for slowing down Alzheimer's disease

<p>A trial drug has shown "significant" results in slowing down Alzheimer's disease, with Australian healthcare experts hopeful in where this breakthrough can take their research. </p> <p>The drug, known as Lecanemab, has been proven to reduce cognitive decline by 27 per cent compared to placebo, according to an overseas study. </p> <p>More than 1,700 patients with mild cognitive impairment were enrolled in the study and the results were collected over 18 months.</p> <p>"Functionally and cognitively, it seems they did better and so that is a dramatic result," Dr Lawrence Honig, one of the study investigators from Columbia University Medical Centre, said.</p> <p>The drug works by removing the build-up of amyloid plaques in the brain which is one of the hallmarks of the disease, which featured in the scans of each study participant. </p> <p>Australian experts are excited about the findings, and how this can further their research. </p> <p>"This is the first time we've seen a drug like this have these kinds of effects," Professor Sharon Naismith, Clinical Neuropsychologist &amp; NHMRC Dementia Leadership Fellow at the University of Sydney, said.</p> <p>"The results of this trial have massive implications for our resourcing."</p> <p>Naismith warns there's a need to spend more money on better diagnosing patients with mild cognitive impairment.</p> <p>"In the past there has been a lot of reluctance from healthcare physicians to diagnose or ask about cognitive impairment, even in primary care," she said.</p> <p>She said being able to access a drug that can slow cognitive decline will change the paradigm and conversation around Alzheimer's disease. </p> <p>"I do think we're going to get a real avalanche of people coming to GPs and coming to memory clinics for that reason," she said.</p> <p>Professor Kathryn Goozee, Director of KaRa Minds at Macquarie Park said the study showed using an antibody to target amyloid in the brain can help with cognition.</p> <p>"To date there has been no disease-modifying medication so we want to be offering studies that can potentially change that trajectory," Goozee said.</p> <p>The full details of the results will be presented at an international conference of experts in the US in late November.</p> <p><em>Image credits: 9News</em></p>

The top 5 hacks to slow down the ageing process

<p><span lang="EN-US">The truth is you no longer have to age the way your parents or grandparents did.  You can age on your own terms, starting now. In our crazy, busy world, the struggle to look after yourself is real, let alone decipher what you really can do that will actually make a difference to the way you age.</span></p> <p><span lang="EN-US"> </span><span lang="EN-US">As women, the expectations are high and we are constantly bombarded with messages that we need to be all things to all people, including ourselves. We need to raise children that are healthy, well educated, kept off computer games and social media but entertained with wholesome play. Add to that maintaining a home, keeping on top the bills and activities, maintaining friendships and family relationships. Plus we need to look great, exercise, sleep well and possibly even manifest our dreams and create incredible careers. PHEW, it is a lot!</span></p> <p><span lang="EN-US">So how do you become more vibrant and youthful without adding complicated routines into your already busy day? It’s about knowing what simple things you can do and understanding the importance of consistency. Small, seemingly insignificant steps taken over time will create a radical difference. You don’t have to be the smartest, fastest or the strongest – you have to be the most consistent.  Let’s take a look at 5 anti-ageing hacks:</span></p> <p><strong><span lang="EN-US">1)     </span><span lang="EN-US">Happiness: </span></strong><span lang="EN-US">Understanding happiness is one of the most significant measures for longevity and it is very empowering to know that we can work on our own happiness.  It has now become a scientific field of research, with evidence indicating that happy people are healthier, have a better immune function and have less heart disease.  Further, happier people have great mental health and can live up to 10 years longer.  We have a certain baseline of happiness and we can raise this with long term strategies rather than the instant gratifications we usually look for.  Learning these tools is highly important when slowing the aging process. These include, not comparing ourselves to others, learning that we can only be happy in the present, letting go of resentment, practicing kindness, being grateful and avoiding perfectionism.</span></p> <p><strong><span lang="EN-US">2)     </span></strong><span lang="EN-US"><strong>Fasting:</strong> </span><span lang="EN-US">Giving your body a rest from having to process what you are putting in to it has extraordinary results. You can choose to fast for a day, or to restrict the time that you are eat in any one day. For example you may choose to eat only between 11am and 7pm. Going into a fasting state not only helps you lose weight but can propel the genes to function better in repairing the body, it can increase levels of Human Growth Hormone and delay aging. Practicing this a couple of times a week consistently will have amazing results over time.</span></p> <p><strong><span lang="EN-US">3)     </span></strong><span lang="EN-US"><strong>Meditation: </strong> </span><span lang="EN-US">Our mind is our most precious and valuable resource and we use it to experience every single moment of our life.  We depend on our mind to be focused and perform at our very best and this is the way to take care of it.  This can be done in a as little as 15 mins a day. Once again consistency is key and this will reduce blood pressure, stress and anxiety, improve sleep, your immune system is boosted and the aging process is slowed.  This is an extremely powerful anti-aging hack.</span></p> <p><strong><span lang="EN-US">4)     </span></strong><span lang="EN-US"><strong>Strength training:</strong>  </span><span lang="EN-US">This is the biggest physical anti-aging hack you can make and you don’t have to spend long hard hours in the gym – 30 minutes twice a week will do it. Not only does this make you look great it reverses the aging process at a cellular level, increases the production of collagen and the anti-aging hormones oxytocin and progesterone.</span></p> <p><strong><span lang="EN-US">5)     </span><span lang="EN-US">Sunscreen and the ingredients in your skincare: </span></strong><span lang="EN-US"> There is no question that maintaining a consistent skincare routine promotes smooth radiant skin. You just need to be aware of the active ingredients in the products you are using.  The most important are Vitamins A B and C. Peptides are also  important to support collagen production. Do you know which active ingredients are in the cream you are using?  Prevention using sunscreen on the face daily is a major hack in the war against aging.</span></p> <p><span lang="EN-US">The majority of the above hacks don’t require you to find more time in your day, they are just a change in how you do things.  A mindset change.  If you were to make these 5 changes to your life right now, you will be a different person in 12 months time.  Whatever you do make sure you tell yourself every day that you matter and that you are worth it and start with one simple step.</span></p> <p><strong>Lyndal Linkin, author of To Age or Not to Age, is a 56-year-old anti-aging expert who’s spent her lifetime learning about anti-aging solutions.

5 common mistakes when using your slow cooker

<p>If you’re a regular user of your slow-cooker, then you’ll know just how handy these appliances are. There’s nothing like throwing some ingredients into the bowl and flicking the ‘ON’ switch of a morning then coming home to a delicious meal a few hours later. To get the best out of your machine avoid making these common mistakes.</p> <p><strong>1. Don’t add raw meat to the slow cooker</strong></p> <p>To get the best flavour from your cut of meat it’s best to brown it first. Meat that’s been quickly seared on the stovetop has a delicious depth of flavour that you just can’t achieve in the crockpot alone.</p> <p><strong>2. Don’t use expensive prime cuts of meat</strong></p> <p>While there aren’t hard and fast rules when it comes to what you put in your slow cooker it’s an appliance designed to get the most out of cheaper, tougher cuts of meat. Long, slow cooking only dries out leaner varieties leaving them rubbery and tasteless. Leave the chicken breast and eye fillet to the oven or stove and try thigh meat and cuts like beef and pork shoulder, leg and cheek.</p> <p><strong>3. Don’t open the lid during cooking</strong></p> <p>It’s tempting, we know, but opening the lid breaks the seal and allows precious heat to escape. Every time you remove the lid, the slow cooker loses heat and it can take a while to build back up again.</p> <p><strong>4. Don’t add too much wine</strong></p> <p>While some recipes call for alcohol to be added, it’s important to check just how much they recommend. Unlike cooking on the stovetop, wine and other liquors don’t boil down and reduce in a slow cooker which can mean a harsh, ‘alcoholic’ flavour. An easy way to use wine and other alcohol in slow cooking is by using it to deglaze the pan you sear the meat in.</p> <p><strong>5. Don’t add dairy products too soon</strong></p> <p>Adding things like milk, sour cream, cream or yoghurt at the beginning of cooking will cause them to curdle. Wait until the very end of cooking to add anything creamy.</p> <p>What’s your favourite slow cooker recipe?

13 natural remedies that can help slow down ageing

<p><strong>Water</strong></p> <p>Considering our body is made up of nearly 60 per cent of the stuff, it seems common sense that drinking enough water could improve our life expectancy. “Drinking adequate water to stay hydrated helps assist in digestion by keeping our gut moist and lubricated, helping our bodies carry nutrition to our cells, as well as in the ridding of waste products,” says osteopath, Barbara Joy Jones. “Aesthetically, it helps keep our skin looking like a fresh grape versus a dehydrated raisin.”</p> <p><strong>Probiotics</strong></p> <p>“Probiotics are ‘good’ gut bacteria that provide many health benefits when part of a healthy diet and supplementation regimen, from immune system integrity to even producing certain vitamins,” explains nutritionist, Dr Roger Adams. “Research has also indicated that probiotics may help improve certain skin conditions like eczema, improve urinary tract health, and even lessen allergy symptoms,” says Adams. While you can get probiotics in many of the foods you eat, such as yoghurt, kimchi, sauerkraut and kefir, you can also up your daily dose with over-the-counter supplements.</p> <p><strong>Collagen peptides</strong></p> <p>You’ve probably noticed that collagen is an ingredient in numerous skin care products on the shelves today, but it’s also found in the body naturally – in joints, bones, muscles and tendons. “It’s the major protein in the body that binds tissues together, and is also known as the body’s scaffolding or supporting structure,” explains Dr Adams. The only issue is that, as we age, our body’s production of collagen starts to decline, which leads to physical signs of ageing such as wrinkles. Taking a collagen supplement, or consuming any protein source rich in proline and glycine, may help increase your body’s production. However, Dr Adams recommends ensuring that your collagen supplement comes from a reputable company.</p> <p><strong>Tumeric</strong></p> <p>This golden ancient spice that gives curry its yellow colour has a slew of anti-ageing benefits, specifically anti-inflammatory and antioxidant protective perks. “The active ingredient, a compound called curcumin, has been found to prevent cognitive decline,” says clinical nutritionist, Dr David Friedman. In other words, if you want to have a sharp mind through the decades, take turmeric. But that’s not all, Dr Friedman points out: studies also show turmeric to be helpful in reversing many of the chronic illnesses associated with ageing like heart disease, Alzheimer’s, diabetes and cancer.</p> <p><strong>Vitamin D</strong></p> <p>If you’re good about staying out of the sun, the downside could mean that you’re not synthesising enough vitamin D – which is actually a hormone that plays a key role in almost all organ systems in the body, explains naturopath, Olivia Rose. “From prevention and treatment of heart disease, osteoporosis, muscle pain and weakness, joint pain, memory issues, prevention of cold and flu, as well as the prevention of cancer and more, optimal levels of vitamin D in the blood should be around 120 nmol/L,” she says. “Older adults also make vitamin D less efficiently than younger individuals, therefore supplementation is key.”</p> <p><strong>Coconut oil</strong></p> <p>Coconut oil’s benefits have been getting a lot of attention – it is incredibly nutrient-dense, and people around the globe use it as a natural remedy for a myriad of ailments. In particular, Dr Adams explains, coconut oil is a good source of antioxidants, which help fight diseases like cancer, heart disease, joint pain and inflammation, and ageing. While he does not recommend taking coconut oil in large amounts, due to the potential negative aspect that it may raise bad LDL cholesterol, he encourages clients to use it sparingly in cooking to impart different flavours and add variety to their diets.</p> <p><strong>Omega-3 fatty acids</strong></p> <p>This heart-healthy fat is essential to good health with a laundry list of benefits, such as improving eye, brain and heart health and fighting depression and anxiety. “Omega-3s, found naturally in the diet in fatty fish like salmon, albacore tuna, mackerel and sardines, and also in other sources like chia, flax and walnuts, are important for helping our body reduce inflammation, improve heart health, and maintain healthy skin,” says Dr Adams. “Omega-3s are also critical for brain functioning and some research shows supplementation may be beneficial during pregnancy for foetal brain and eye development.” He usually recommends clients take 2.5-3 grams of omega-3 per day, but be sure to consume with food to increase absorption and minimise any gastrointestinal upset.</p> <p><strong>Green tea</strong></p> <p>For centuries, healers have hailed this beverage as a longevity booster. In fact, one study published in the <em>Annals of Epidemiology</em> found that individuals who consume green tea on a regular basis are at a lower risk for heart disease and premature death. Additionally, green tea has brain-boosting benefits – it seems to enhance memory and increase attention. Aim to drink one to two cups of green tea daily, ideally in place of your coffee.</p> <p><strong>Dark chocolate</strong></p> <p>Perhaps the most appealing natural anti-ageing remedy, dark chocolate may keep you young thanks to its rich antioxidant content. One study from the <em>British Journal of Clinical Pharmacology</em> showed antioxidants in dark chocolate – mainly flavonoids – protect the brain from age-related cognitive decline. What’s more, Dr Friedman notes, eating dark chocolate regularly can have positive effects on the skin by reducing facial wrinkles, helping protect against sun exposure, and improving skin elasticity.</p> <p><strong>Blueberries</strong></p> <p>These yummy, round berries are more than delicious: they also contain an age-defying antioxidant called anthocyanin, which research has found to possess powerful anti-inflammatory effects. “In addition, blueberries increase brain signalling, which improves memory and helps balance glucose levels, which may combat neurodegeneration linked to Alzheimer’s disease,” says Dr Friedman. “Also, research from the Harvard School of Public Health shows regular consumption of blueberries can reduce the risk of heart attack in women by 32 per cent.”</p> <p><strong>CBD oil</strong></p> <p>You may have heard about the anxiety-reducing and sleep-enhancing benefits of CBD oil, but did you know it can improve circulation, reduce heart issues, and prevent the kind of high blood pressure linked to ageing? “CBD oil derived from cannabis has been shown to reduce blood pressure and improve circulation, although there have not been a lot of studies because cannabis has been illegal for many years,” says naturopath, Dr Lynn Anderson. “CBD oil removes the THC, which is the compound that causes the ‘high’ for cannabis,” she explains.</p> <p><strong>Grapeseed oil</strong></p> <p>This oil, a byproduct of wine-making, also serves as an anti-ageing remedy, according to Dr Rose. “Used topically, grapeseed oil can strengthen hair strands when added to your regular hair conditioning regimen and it can also be used as an all-natural makeup remover, which will also help reduce the appearance of fine lines due to its incredible antioxidant properties,” she says. “Grapeseed oil is rich in vitamin E, a vitamin and antioxidant known to be helpful for the prevention of heart disease, particularly when it’s consumed as food.” She recommends using it straight or adding a few drops to your favourite moisturiser or adding a teaspoon to a facial mask of ripe avocados.</p> <p><strong>Yucca root</strong></p> <p>This root vegetable that’s native to subtropical climates, mostly South America, is rich in carbohydrates and serves as an excellent source of fibre, vitamin C, potassium and folate (an essential nutrient for pregnant women). It also happens to help with creaking joints, a sign of arthritis. “Arthritis, like many diseases, is inflammation-related, and yucca root extract happens to be an ancient natural remedy for inflammation,” says Dr Anderson. “Yucca is a good source of saponins, which may have anti-arthritic properties by suppressing intestinal protozoa which may have a role in joint inflammation.”</p> <p><em><span id="docs-internal-guid-1e0866d5-7fff-33e6-15e2-14e248dbd11e">Written by Jenn Sinrich.

Move over, Iron Chef, this metallic cook has just learned how to taste

<p>In an episode of <em>Futurama</em>, robot Bender wants to be a chef, but has to overcome the not inconsiderable hurdle of being incapable of taste. It was beautiful.</p> <p>Move over, Bender. A new robot has not only been programmed to taste, it has been trained to taste food at different stages of the cooking process to check for seasoning. Researchers from the University of Cambridge, UK, working with domestic appliances manufacturer Beko, hope the new robot will be useful in the development of automated food preparation.</p> <p>It’s a cliché of cooking that you must “taste as you go”. But tasting isn’t as simple as it may seem. There are different stages of the chewing process in which the release of saliva and digestive enzymes change our perception of flavour while chewing.</p> <p>The robot chef had already mastered the <a href="https://www.cam.ac.uk/research/news/a-good-egg-robot-chef-trained-to-make-omelettes" target="_blank" rel="noreferrer noopener">omelette</a> based on human tasters’ feedback. Now, results <a href="https://dx.doi.org/10.3389/frobt.2022.886074" target="_blank" rel="noreferrer noopener">published</a> in the <em>Frontiers in Robotics & AI</em> journal show the robot tasting nine different variations of scrambled eggs and tomatoes at three different stages of the chewing process to produce a “taste map”.</p> <p>Using machine-learning algorithms and the “taste as you go” approach, the robot was able to quickly and accurately judge the saltiness of the simple scrambled egg dish. The new method was a significant improvement over other tasting tech based on only a single sample.</p> <p>Saltiness was measured by a conductance probe attached to the robot’s arm. They prepared the dish, varying the number of tomatoes and amount of salt. “Chewed” food was passed through a blender, then tested for saltiness again.</p> <figure class="wp-block-video"><video src="../wp-content/uploads/2022/05/Unchewed-sampling-short.mp4" controls="controls" width="300" height="150"></video><figcaption>This robot ‘chef’ is learning to be a better cook by ‘tasting’ the saltiness of a simple dish of eggs and tomatoes at different stages of the cooking process, imitating a similar process in humans.

In our experiment, the robot can ‘see’ the difference in the food as it’s chewed, which improves its ability to taste.”</p> <p> “We believe that the development of robotic chefs will play a major role in busy households and assisted living homes in the future,” said senior Beko scientist Dr Muhammad W. Chugtai. “This result is a leap forward in robotic cooking, and by using machine and deep-learning algorithms, mastication will help robot chefs adjust taste for different dishes and users.” Next on the menu will be training robots to improve and expand the tasting abilities to oily or sweet food, for example. Sounds pretty sweet.</p> <p><!-- Start of tracking content syndication.

5 things you should never cook in an air fryer

<p>You can air fry almost anything. And why wouldn’t you want to? There’s a reason these appliances have seemingly taken over everyone’s kitchens. Air fryers can imitate the results of deep-frying with some intense hot air and only a fraction of the oil. With this healthier alternative, crispy foods don’t have to be reserved for nights out and special occasions. But, there are foods that just shouldn’t be seen near an air fryer. Before cooking with your air fryer, see which foods won’t work – even though they may be tempting to throw in there.</p> <p><strong>Battered foods</strong></p> <p>Unless the food is pre-fried and frozen, you’ll want to avoid placing wet batter in the air fryer. Aside from the obvious mess it will create, wet batter won’t set the way it does when it’s submerged in oil, meaning the food won’t have that crunchy shell. If you’d like to add a little crispiness to your food, coat in flour, egg, and breadcrumbs.</p> <p><strong>Fresh greens</strong></p> <p>Leafy greens, like spinach, will cook unevenly and are very likely to burn due to the air fryer’s high-speed air. When choosing vegetables to cook in the air fryer, make sure they hold some weight, like broccoli or zucchini. Kale chips may also be successful if coated in enough oil to weigh them down. Ultimately, experts say that frozen veggies are the way to go when it comes to air fryers because they retain more moisture from the ice.</p> <p><strong>Whole roasts</strong></p> <p>The apparent issue with whole roasts is whether or not it will even fit properly into an air fryer basket, but even if it does fit, it’s best to just stick to the regular oven. The roast will not cook evenly, with the part closest to the heat source likely to burn by the time the part furthest away is safe to eat. The problem comes down to overcrowding. Since the hot air needs room to appropriately circulate, the most successful method would be to cook the roast in smaller pieces. If cooking a chicken, make sure the skin is facing up as air fryers heat from the top.</p> <p><strong>Cheese</strong></p> <p>Who wouldn’t love to instantly make some fried cheese to snack on? Since the air fryer isn’t truly ‘frying’ the food, placing cheese in it without some sort of coating will just melt the cheese into a puddle and create a mess you don’t want to clean up.</p> <p><strong>Raw grains</strong></p> <p>Grains such as rice and pasta can crisp nicely in an air fryer, but they have to be cooked on the stovetop first. Air fryers are intended to dry cooked food, so trying to cook something that needs to be immersed in water to cook properly won’t work. Even with an insert that allows you to place water inside the air fryer, the fan will never get hot enough to boil the water and successfully cook your grains.</p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/kitchen-tips/5-things-you-should-never-cook-in-an-air-fryer" target="_blank" rel="noopener">Reader’s Digest</a>.</em></p>
