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.

Garden fixes after heavy rain

<p><em><strong>Better Homes and Gardens’ resident landscaper, Jason Hodges, shares his advice for tending to the garden after heavy rain.</strong></em></p> <p>When it comes to the garden and heavy rain, you need to be prepared. Where does water sit? What gets washed away? How are your drains working or failing? All things you can repair and get working for the future success of your garden.</p> <p>The heavy rain has saturated our soil, and strong winds have toppled over trees all week, but long-term, the saturated soil can hurt all plants in the garden. When the soil is water-logged the root system can drown from lack of oxygen. The first thing I would do is rake some mulch away allowing for some evaporation, either with a garden fork or even something like a cricket stump. Make some holes to allow air in and for the water to fill and again evaporate.</p> <p>Snails and slugs are opportunists and thrive and reproduce when times are good – they love the rain and the wet conditions afterwards. To control them I like to use a take-away container with a splash of beer in it. Placed level with the garden bed the snails go in and never leave.</p> <p>If your garden was flooded don’t be too quick to think the water’s gone down and everything’s fine. If they’re in the garden, avoid eating leafy vegetables such as lettuce, kale and spinach. They may have been contaminated by the flood water. Fruit trees such as citrus should be fine within a short period of time.</p> <p>Now that it has stopped raining it’s never too late to clean the gutters. Overflowing gutters can damage gardens and undermine the footings of your house. When you’re up a ladder either doing the gutters or any other job in the garden I recommend you have a second person with you, an extra set of hands to hold the ladder, spot problems and just pass you tools. It makes the process a lot safer and quicker.</p> <p>Look out for mould, moss and mildew that might grow on shady, damp paths over the next few weeks. A blast with a pressure washer will be a quick fix and a lot more enjoyable than slipping A over Z. A weak solution of vinegar and water will kill mould and mildew if you don’t have a pressure washer.</p> <p>Look for branches that may have been damaged but are still hanging in the tree. They will become more obvious as the foliage browns off and dies. Cleaning up the tear and damage will give the tree a better chance of recovery.</p> <p>If you have a watering system, override it and turn it off for a couple of weeks. The last thing the garden needs is a drink. If your pots were full of water remove the saucers and allow them to drain.</p> <p>It’s a hard time to garden after heavy rain, but let’s be thankful for it and hope we can enjoy the long-term benefits of having moisture deep down in our soil.</p> <p><em>Written by Jason Hodges.

Child marriage comes with a heavy cost for young girls in Africa – but there’s one clear way out

<p>650 million women and girls alive today were married before their 18th birthday. That’s one of the startling figures contained in a <a href="https://data.unicef.org/wp-content/uploads/2021/11/Towards-Ending-Child-Marriage-report-2021.pdf" target="_blank" rel="noopener">2021 UNICEF report</a> about child marriage. Africa’s sub-Saharan region is home to <a href="https://data.unicef.org/topic/child-protection/child-marriage/" target="_blank" rel="noopener">nine of the ten countries</a> with the highest rates of child marriage in the world.</p> <p>Ingrained traditions and cultural practices typically entrench such early marriages. State or customary laws in <a href="https://www.unfpa.org/sites/default/files/pub-pdf/MarryingTooYoung.pdf#page=12" target="_blank" rel="noopener">146 countries</a> allow girls younger than 18 to marry with the consent of their parents or other authorities. In <a href="https://www.unfpa.org/sites/default/files/pub-pdf/MarryingTooYoung.pdf#page=12" target="_blank" rel="noopener">52 nations</a>, girls under 15 can marry with parental consent.</p> <p>Early marriage among boys is <a href="https://www.unicef.org/press-releases/115-million-boys-and-men-around-world-married-children-unicef" target="_blank" rel="noopener">also widespread</a>, though the numbers are far lower than they are for girls and young women.</p> <p>And it is girls and young women who pay the heaviest costs for early marriage. Girls who marry before 18 are <a href="https://data.unicef.org/wp-content/uploads/2021/11/Towards-Ending-Child-Marriage-report-2021.pdf" target="_blank" rel="noopener">more likely</a> to be subjected to domestic violence and less likely to continue schooling than their peers. They have worse economic and health outcomes, a burden they almost inevitably pass on to their children.</p> <p>Early marriage has been linked to poorer <a href="https://www.wider.unu.edu/sites/default/files/Events/PDF/Slides/1_khatoon.pdf" target="_blank" rel="noopener">cognitive development</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0277953617303283" target="_blank" rel="noopener">stunting</a> among the children of such women.</p> <p>Today, the practice is declining thanks to national and international policies, global treaties and, since 2016, the UNFPA-UNICEF Global Programme to End Child Marriage. But gains have been slow in sub-Saharan Africa.</p> <p>What is it that drives the practice in the region? That’s what we examined in a <a href="https://journals.sagepub.com/doi/10.1177/0021909620966778" target="_blank" rel="noopener">recent study</a>. Using statistical analysis, we looked at the socio-economic and demographic determinants of early marriage among young women the Democratic Republic of Congo (DRC), Malawi, Mali and Niger. Each of the four countries has sought to introduce measures to discourage early marriage, but their challenges remain formidable.</p> <p>We explored several possible explanations and variables: age at first intercourse, education and literacy, women’s current age, region and type of place of residence, family wealth index, ethnicity, employment status, and even mass media exposure.</p> <p>One factor stands out across the four countries in our study: education. Women without formal education are more likely to marry early than those who completed secondary or higher education.</p> <h2>Four study countries</h2> <p>The four countries have a great deal in common, including high poverty levels and substantial under-15 and rural populations.</p> <p>In each country, around 50% of people are younger than 15, and around half of the countries’ respective populations live in rural areas (a full 84% in the case of <a href="https://malawi.unfpa.org/sites/default/files/resource-pdf/2018%20Malawi%20Population%20and%20Housing%20Census%20Main%20Report%20%281%29.pdf#page=23" target="_blank" rel="noopener">Malawi</a>).</p> <p>Among the four countries in our study, Niger has the highest child marriage prevalence worldwide – 76% of girls are married before the age of 18. The rates stand at 52% in Mali, 42% in Malawi, and 37% in the DRC.</p> <p>For our analysis, we turned to the most recently available demographic and health surveys from each of the four countries. We then applied a framework that seeks to describe the important social-cultural and cognitive variables and their interrelationships that underlie behaviours and decisions around reproductive health.</p> <h2>Statistical variables</h2> <p>The answers we found as to why early marriage is so commonplace in these countries were not always clear-cut. What’s more, there were lots of statistical variations across the four countries and contradictions, as was to be expected.</p> <p>For example, the average age of first marriage ranged from 15.3 in Niger to 17.1 in Malawi. There was also a range in the percentage of women from the poorest wealth category in the countries who had been married by 18: Niger (90.9%), Mali (80%), DRC (70.3%), Malawi (63.1%).</p> <p>Rates of early marriage dropped among women from richer categories, but were still high: Niger (72.7%), Mali (65.4%), DRC (60.3%) and Malawi (42.5%).</p> <p>The study also showed that young women living in rural areas were likely to marry earlier than those from urban areas.</p> <p>These variations’ social, economic, and cultural underpinnings are likely complex and would need some unpacking. In some cultures, for example, girls are married off young as they are considered to be more likely to be virgins still and can thus fetch a higher payment of what’s known as the <a href="https://www.globalcitizen.org/en/content/child-marriage-brides-india-niger-syria/" target="_blank" rel="noopener">bride price</a>.</p> <p>Amid the many statistical variables that emerged, we were especially struck by the relationship between educational levels and average age at first marriage.</p> <h2>The role of education</h2> <p>We found that the average age at first marriage in Niger, Mali, DRC, and Malawi increased from young people with no education (15.1, 15.4, 16.2, and 16.4, respectively) to those with secondary and higher education (17.0, 16.6, 17.1 and 18.5 in that order).</p> <p>In addition, we saw that the highest prevalence of early marriage (by 18 years) was found among young women with no education (90.6%, 80.3%, 70.9%, and 70.3%). It was lowest among women with secondary and higher education (64.2%, 62.9%, 58.9%, and 30.2%).</p> <p>Malawi is the only one of the four countries where school education is universal, accessible and compulsory.</p> <p>Education offers young women opportunities in life. In some African cultures, however, allowing girls to finish or even attend school <a href="https://www.girlsnotbrides.org/learning-resources/child-marriage-and-education/" target="_blank" rel="noopener">is discouraged</a> as it is feared that an educated girl is less likely to get a husband or be a good wife.</p> <p><a href="https://www.girlsnotbrides.org/learning-resources/child-marriage-atlas/atlas/malawi/" target="_blank" rel="noopener">In Malawi</a>, less than 15% of women have any secondary school education, and 42% of girls are married before the age of 18 – the twelfth highest rate of child marriage in the world.</p> <h2>Next steps</h2> <p>There is an urgent need for governments in these countries to introduce programmes that promote delaying the age at which girls first have sex and to equip adolescents with knowledge about responsible and safer sex.</p> <p>Policymakers should also work to promote prolonged enrolment in school for adolescent girls. And, crucially, laws are needed – and must be enforced – that criminalise child marriages.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/child-marriage-comes-with-a-heavy-cost-for-young-girls-in-africa-but-theres-one-clear-way-out-190924" target="_blank" rel="noopener">The Conversation</a>. </strong></p> <p><em>Image: Shutterstock</em></p>

Liking death metal doesn’t mean you’re a bad person

<div class="copy"> <p>Listening to the music of a band called <a href="https://en.wikipedia.org/wiki/Bloodbath" target="_blank" rel="noopener">Bloodbath</a> – described as “a Swedish death metal supergroup” – is not, it must be said, an exercise recommended for people of delicate disposition who rather like the songs of Celine Dion.</p> <p>However, 48 men and women with no particular love of razoring guitars, thundering drums and screamed lyrics from albums with titles such as Resurrection Through Carnage and The Arrow of Satan is Drawn did just that recently, in the name of scientific endeavour.</p> <p>Researchers led by Yanan Sun from Australia’s Macquarie University set out to test the hypothesis that exposure to music full of violent themes decreases sensitivity to other types of violent imagery.</p> <p>To do this, the researchers first recruited a cohort of 32 self-declared fans of death metal, having first ascertained that the volunteers were particularly fond of lyrics about murder and mayhem and massacre. A second, slightly larger, cohort of non-metal-heads was then also gathered.</p> <p>Individuals in both groups were asked to listen to two songs – a Bloodbath number called ‘Eaten’ and the relentlessly jolly ‘Happy’ by Pharrell Williams.</p> <p>While they were doing so, Sun and colleagues presented them with pairs of images – one in front of each eye – comprising something truly nasty and another, neutral image.</p> <p>“Consistent with past research, violent imagery should generally dominate consciousness over neutral imagery,” the researchers hypothesised.</p> <p>“Moreover, for most people, this tendency to perceive violent images should occur earlier and for longer durations while listening to violent music than while listening to non-violent music, reflecting a ‘congruence effect’ in which emotions experienced while listening to music reinforce the emotions expressed in images.”</p> <p>In addition, the researchers expected, not unreasonably, that metal-heads would experience more positive emotions while listening to Bloodbath because, well, they liked that sort of thing.</p> <p>The results, when the experiments were done and the lab fell, at last, blessedly quiet, were quite a surprise.</p> <p>Both cohorts exhibited general negativity towards the violent imagery. For the Pharrell fans, the bias was stronger when they were listening to Bloodbath, and the metal-heads showed an equal bias through both songs.</p> <p>“The results of this investigation confirm that both fans and non-fans of violent music exhibit a reliable bias for processing violent imagery over neutral imagery regardless of what genres of music they were listening to,” the researchers state.</p> <p>“Thus, we observed no evidence that fans of violent music are generally desensitised to violence.”</p> <p>The results may disturb some critics who view heavy metal music as a kind of sonic gateway drug to antisocial behaviour, but probably won’t come as a shock to metal fans themselves.</p> <p>“For listeners who extract a positive experience from violent or aggressively themed music — even when they recognize that the music expresses violence — music will not reinforce a processing bias for violent imagery any more than a positively themed song such as ‘Happy’,” concludes Sun’s team.</p> <p>The research is <a href="https://royalsocietypublishing.org/doi/10.1098/rsos.181580" target="_blank" rel="noopener">published</a> in the journal <em>Royal Society Open Science</em>.</p> <p><em>Image credits: Getty Images</em></p> <div class="newsletter-box"> <div id="wpcf7-f6-p24438-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> <form class="wpcf7-form mailchimp-ext-0.5.56 spai-bg-prepared init" action="/people/society/liking-death-metal-doesnt-mean-youre-a-bad-person/#wpcf7-f6-p24438-o1" method="post" novalidate="novalidate" data-status="init"> <p> </p> </form> </div> </div> <p><em><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=24438&amp;title=Liking+death+metal+doesn%E2%80%99t+mean+you%E2%80%99re+a+bad+person" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></em></div> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/people/society/liking-death-metal-doesnt-mean-youre-a-bad-person/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Andrew Masterson. </em></p> </div>

Inside Olivia Newton-John's $5.7 million Aussie mansion: "Selling with a heavy heart"

<p>After owning the extravagant home for 40 years, it’s with a heavy heart that Olivia Newton-John has decided to sell her home in Ballina, in northern NSW. Newton-John has trusted her longtime friend and now real estate agent Jillian McGrath with the sale of her 187-acre home, which has an asking price of $5.5 million.</p> <p>“We flew up to the area during her 1980<span> </span><em>Grease</em>-era as she wanted somewhere she would have extreme privacy,” McGrath explained.</p> <p>“Since then she bought up adjoining properties, had over 4000 trees planted and has created a beautiful sanctuary.</p> <p>“She hopes that the person who buys this will live here full-time or a family will enjoy it; she wants someone to love it as much as she has.”</p> <p>McGrath made a point to mention that the decision to sell the beloved home has nothing to do with Newton-John’s health, as she has recently been diagnosed with cancer for the third time.</p> <p>“This decision is nothing to do with her health," the real estate agent noted. </p> <p>“It’s an ideal residence or maybe for someone who wants it as a holiday escape, as it has been this to her.”</p> <p>The luxury escape has four bedrooms, three bathrooms, a creek, two dams and a tennis court.</p> <p>Scroll through the gallery above to see inside Newton-John's magnificent property. </p> <p><em>Photo credits: Domain.com.au</em></p>

Why Prince Harry and Meghan are under heavy guard

<p>Newlyweds Prince Harry and Meghan have been given extra security protection – the same level as the Queen and the British Prime Minister – because of comments former soldier Harry made back in 2013.</p> <p>British special forces are guarding the Duke and Duchess of Sussex with sub-machine guns amid fears the couple could be targeted by the Taliban.</p> <p>In 2013, Harry boasted of blowing “Taliban extremists to pieces” and confirmed he killed Taliban fighters.</p> <p>When asked if he had killed on duty he said, “Yeah, so lots of people have. The squadron’s been out here. Everyone’s fired a certain amount.”</p> <p>He added: “Take a life to save a life, that’s what we revolve around, I suppose. If there’s people trying to do bad stuff to our guys, then we’ll take them out of the game, I suppose.”</p> <p>The comments caused a stir at the time with the Taliban responding, telling  <a href="https://www.theguardian.com/uk/2013/jan/22/afghanistan-taliban-response-prince-harry">The Guardian</a>: “I think he has a mental problem, that’s why he is saying it is a game. These kind of people live like diplomats in Afghanistan, they can’t risk themselves by standing against the mujahideen [holy warriors].”</p> <p>According to <a href="https://www.thesun.co.uk/news/6387472/meghan-markle-and-prince-harrys-countryside-lovenest-is-now-guarded-by-anti-terror-cops-armed-with-sub-machine-guns/">The Sun</a>, Harry’s comments have come back to haunt him five years on.</p> <p>While the couple are well protected at Kensington Palace, the royal couple’s countryside home has been beefed up with the same level of anti-terrorist security provided at Buckingham Palace and that protects UK Prime Minister Theresa May and spy bases.</p> <p>The property is also on a list of properties where members of the public risk being jailed for six months if they are found trespassing.</p> <p>Locals near the country pad in Cotswolds, in south central England, have reported being stopped by heavily-armed officers, who are believed to be on patrol in the area. </p> <p>Security for the royal wedding costs £30 million in what became one of the most heavily-guarded events in history.</p>

The therapeutic benefits of heavy blankets

<p>Have you ever curled up with a thick, heavy blanket and felt a near-instant sense of relief? Perhaps it's been your duvet you've hidden under after a particularly bad day at work, or a quilt you pull out of the closet specifically for wrapping around you during weekend hot chocolates during winter. </p> <p>There's some research that explains why heavy or even weighted blankets are beneficial for sleep and overall mental health. They're an often-used tool by occupational therapists – especially with children – but can be incorporated in anybody's home to help you relax and encourage feelings of calm.</p> <p><strong>Deep pressure touch stimulation</strong></p> <p>The science behind why heavy blankets work is called deep pressure touch stimulation (DPTS). While from a clinical occupational therapy standpoint it has been found that light touch on a person's body can increase tension or alert the system, the opposite can be said for heavy touch. This therapy involves firm pressure, holding, stoking, petting (e.g. of animals).</p> <p>Most of us would have actually received a form of DPTS when we were babies by way of swaddling, which is the practice of wrapping a child tightly in a blanket to restrict movement. This, in turn, can make a baby feel safe and secure, and may help them sleep.</p> <p>The pressure from DPTS works to relax your nervous system, hence being useful for sleep and those that struggling with the symptoms of anxiety at night. Pressure on the body helps generate serotonin which then converts to melatonin, the chemical that tells your system it’s time to rest.</p> <p><strong>Heavy vs. weighted blankets</strong></p> <p>There is actually a difference between a heavy blanket and a weighted blanket, the latter which is usually used in a clinical setting.</p> <p>A heavy blanket may simply be one with a high down or wool content. Think one of those very expensive down duvet inners (they run up to about $900) or, conversely, one of your grandma's ultra-thick war-era woollen blankets.</p> <p>A weighted blanket, available online or <span style="text-decoration: underline;"><strong><a href="https://www.youtube.com/watch?v=svqiyDlJmus&amp;feature=youtu.be" target="_blank">you can sew your own</a></strong></span>, has pellets sewn into quilted pockets to evenly distribute weight. To receive the benefits of a heavy or weighted blanket, it's suggested you seek something that weighs between six and 12 kilograms – generally you want it to be about 10 per cent of your body weight.</p> <p><strong>Are weighted blankets really suitable for children?</strong></p> <p>A review of research by the <em>Journal of Child and Adolescent Psychopharmacology</em> found that weighted blankets can benefit children with behavioural or sensory processing disorders. Children with ADHD and disorders on the autism spectrum have seen detectable levels of calming during DPTS.</p> <p>If you have a neurotypical child, however, they may still benefit. The reports are primarily anecdotal (rather than scientific) but heavy blankets weighing 5-10 per cent of a child's body weight can provide better sleep.</p> <p><strong>Is it safe?</strong></p> <p>According to a paper published in Occupational Therapy and Mental Health, a 12-kilogram blanket when used lying down is safe by all vital sign metrics. This study also found that electrodermal activity (the variation of electrical characteristics on the skin) is reduced by 33 per cent, while 63 percent of users report lower anxiety levels and 78 per cent preferred the blanket as a "calming modality". Other studies have found similar results.</p> <p><strong>Do they really work?</strong></p> <p>However, weighted blankets can't be considered revolutionary from insomnia and anxiety sufferers. The company Gravity, which raised US$3 million <span style="text-decoration: underline;"><strong><a href="https://www.kickstarter.com/projects/1620645203/gravity-the-weighted-blanket-for-sleep-stress-and/description" target="_blank">on its Kickstarter page</a></strong></span> to manufacture its weighted blanket, got into hot water last week after making statements about the benefits of the product that fell out of line with health claims policies.</p> <p>The website, <span style="text-decoration: underline;"><strong><a href="https://www.statnews.com/2017/05/12/gravity-blanket-anxiety-fda/" target="_blank">which has since been changed</a></strong></span>, claimed "the science behind Gravity reveals that it can be used to treat a variety of ailments, including insomnia, post-traumatic stress disorder, obsessive-compulsive disorder, attention deficit hyperactivity disorder, as well as circumstantial stress and prolonged anxiety." </p> <p>This, of course, is an overstatement and blankets have not been shown in studies to "treat" any of these problems, but rather just aid in their symptoms for some people.</p> <p><em>Written by Lee Suckling.

Pilots skilfully land in heavy crosswinds

<p>We take so many elements of air travel for granted these days, that we sometimes lose sight of the considerable skill required from pilots to provide us with safe travel.</p> <p>The skill is really on display in the video above, which shows a pilot making a landing in heavy crosswinds.</p> <p>From our perspective it looks quite nerve wracking as the plane approaches the runway at a 45 degree angle. But, rest assured the pilot knows exactly what he’s doing.</p> <p>A spokesperson for Trans States told Huffington Post the routine is part of pilot training, “All of our pilots are trained to land in heavy cross winds... this pilot did a great job of executing his training.”</p> <p>Routine or not, after watching this video we think this pilot deserves a pat on the back! </p> <p><em>Video credit: YouTube / ElDI SuperNova</em></p> <p><strong>Related links:</strong></p> <p><span style="text-decoration: underline;"><em><strong><a href="/travel/international-travel/2016/03/hippo-stuns-guests-by-swimming-in-pool/">Hippo stuns guests by taking a swim in the pool</a></strong></em></span></p> <p><span style="text-decoration: underline;"><em><strong><a href="/travel/international-travel/2016/03/fairytale-like-travel-experiences/">7 travel experiences straight out of a fairytale</a></strong></em></span></p> <p><span style="text-decoration: underline;"><em><strong><a href="/travel/international-travel/2016/03/farmer-plants-6000-trees-in-touching-tribute-to-late-wife/">70-year-old farmer plants 6,000 trees in tribute to late wife</a></strong></em></span></p>
