Australian women are less likely to receive pre-hospital stroke care than men

<p>Paramedics are failing to recognise strokes in women as much as they do for men, according to a new <a href="https://newsroom.unsw.edu.au/news/health/women-less-likely-receive-pre-hospital-stroke-care-men" target="_blank" rel="noreferrer noopener">study</a> of New South Wales stroke patients. Researchers suggest that clinician sex bias might be the cause.</p> <p>In 2018 it was <a href="https://www.aihw.gov.au/reports/heart-stroke-vascular-diseases/hsvd-facts/contents/heart-stroke-and-vascular-disease-and-subtypes/stroke" target="_blank" rel="noreferrer noopener">estimated</a> that 387,000 Australians aged over 15 years had experienced a stroke at some point in their lives. The success of treatment is very time dependent, so it’s critical that patients suffering from stroke are identified as soon as possible, preferably before arriving at hospital.</p> <p>But according to the study by Australian researchers, women (aged under 70) suffering with stroke were less likely than men to receive stroke care management prior to hospital admission – despite being more likely to arrive at hospital by ambulance.</p> <p>This is concerning, as other research shows stroke outcomes are <a href="https://pubmed.ncbi.nlm.nih.gov/31719135/" target="_blank" rel="noreferrer noopener">generally worse</a> for women than men – with greater stroke-related disability and poorer subsequent quality of life.</p> <p>“Our study suggests that better recognition of stroke symptoms in women by ambulance staff could ensure the right treatment is started as early as possible and give them the best opportunity for recovery,” says lead author Dr Xia Wang, research fellow at The George Institute for Global Health in Sydney.</p> <p>There are two types of stroke: ischaemic stroke occurs when a vessel supplying blood to the brain becomes blocked, and haemorrhagic stroke occurs when one ruptures and begins to bleed. This can cause parts of the brain to die – resulting in impairment that can affect things like speech, movement, and communication – or can often be fatal.</p> <p>Thanks to development in medical research <a href="https://www.nhs.uk/conditions/stroke/treatment/" target="_blank" rel="noreferrer noopener">treatment for stroke</a> is changing, but the efficacy of these treatments is highly time-dependent and rapid and accurate pre-hospital assessment is critical for successful outcomes.</p> <p>“When stroke is not recognised early, delays can have serious consequences,” says co-author Dr Cheryl Carcel, senior research fellow and academic lead of the George Institute’s Global Brain Health Initiative.</p> <p>“Procedures for in-ambulance stroke care ensure patients with stroke symptoms are brought to a high-level specialised facility quickly to receive life-saving treatment.”</p> <p>In a population-based cohort study, researchers analysed data from more than  200,0000 patients (51% women) admitted to NSW hospitals between July 2005 and December 2018 and subsequently diagnosed as having a stroke.</p> <p>Just over half of all stroke patients were taken to hospital via ambulance, with women (52.4%) more likely than men (47.9%) to arrive this way.</p> <p>Despite this, women were less likely to receive stroke care management prior to hospital admission.</p> <p>“Among patients under 70 years of age, women were less likely than men to be assessed by paramedics as having a stroke, but there was no significant difference for older patients,” the authors say.</p> <p>Instead, they were more frequently assessed by paramedics as having conditions which mimic stroke – like headache or migraine, anxiety, and unconsciousness – which contributed to a delay in the recognition and treatment of stroke.</p> <p>There was no significant difference for older patients.</p> <p>Health professionals know that on initial presentation, <a href="https://pubmed.ncbi.nlm.nih.gov/31114842/" target="_blank" rel="noreferrer noopener">atypical clinical symptoms of stroke</a> occur more frequently in women. So, these findings could be due to a difference in symptoms, although it’s also possible that implicit sex bias exists amongst healthcare providers.</p> <p>“While there aren’t any studies looking at clinician sex bias in stroke, we have evidence from other countries where it is happening in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3810172/" target="_blank" rel="noreferrer noopener">coronary artery disease</a>,” explains Carcel.</p> <p>This has also been <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002870321001885?via%3Dihub" target="_blank" rel="noreferrer noopener">found</a> to be the case for myocardial infarction (heart attack), with women less likely to be assessed by paramedics as having MI than men.</p> <p>“Greater awareness among all health professionals about differences in symptom presentation between men and women could help address this bias,” concludes Carcel. “In the case of stroke, this is particularly important for ambulance staff, so that women are identified early and treatment is commenced even before they reach the hospital.”</p> <p>This article originally appeared on <a href="https://cosmosmagazine.com/people/australian-women-stroke-care/" target="_blank" rel="noopener">Cosmos</a>. </p> <p><em>Image: Getty</em></p>

Australia’s greater glider now an endangered species

<p>This week’s assignment of ‘endangered’ status to the greater glider may surprise many Australians, but for experts it’s hardly unexpected.</p> <p>On Tuesday, Australia’s environment minister Tanya Plibersek accepted advice from the government’s threatened species scientific committee to ‘uplist’ the conservation status of the southern and central <a href="https://cosmosmagazine.com/nature/greater-glider-glide-into-your-heart/" target="_blank" rel="noreferrer noopener" data-type="post" data-id="193138">greater glider</a> (Petauroides volans), a large marsupial that calls forests along Australia’s east coast home.</p> <p>It’s the largest of eastern Australia’s gliding possums (at least another eight are found here), known for its furry body, teddy bear-esque ears, and a canopy-like membrane that allows it to slide through the air. Individuals typically reside in ‘dens’ provided by old eucalyptus tree hollows. Some eucalypts provide the leaves that serve as their primary source of food.</p> <p>But the destruction of vital habitat during the catastrophic <a href="https://cosmosmagazine.com/earth/climate/what-fuelled-australias-black-summer-fires/" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://cosmosmagazine.com/earth/climate/what-fuelled-australias-black-summer-fires/">Black Summer</a> bushfires in 2019-20 has pushed glider populations of the species to the brink.</p> <h2>Extended family: greater gliders are separate species and are all likely under threat</h2> <p>The greater glider was first listed as vulnerable in 2016, and was considered one species – P. volans. But since 2020, experts consider the glider to be at least three distinct species.</p> <p>P. volans inhabits forests from Proserpine in the Whitsunday region of Queensland down the continent’s east coast to the forested areas surrounding Melbourne, Victoria. P. minor occupies the wet-dry tropical region near Townsville and Cairns north-eastern Australia, and has been now added to the threatened species list as ‘vulnerable’.</p> <p>A third species – P. armillatus – is considered vulnerable by Queensland’s government, and likely faces the same pressures as the others.</p> <p>“The taxonomy of the gliders is not completely resolved as yet,” explains Professor David Lindenmayer of the Australian National University, Canberra. “There may be up to five species of greater gliders, and it’s unlikely that any of them will be secure in number.</p> <p>“We’re going to have to work hard to make sure that we can conserve all of those species because it’s all an important part of Australia’s natural heritage.”</p> <p>There is encouraging language from the Australian government, with environment minister Plibersek publicly backing efforts to help gliders recover from the Black Summer bushfires. But while those fires had a devastating effect on numerous plant and animal populations, other factors like climate change, habitat clearing and fragmentation and timber harvesting pose existential threats to glider survival.</p> <p>“All these various threats and factors interacting in different ways ultimately increase the risk of extinction,” says Luke Emerson, a researcher at Deakin University’s Centre for Integrative Ecology who specialises in the ecology of arboreal marsupials like the glider.</p> <p>“Rising temperatures, increasing fire severity, shorter fire intervals, logging on top of that, conversion and fragmentation of habitat… all these things are interacting to put greater pressure on arboreal marsupials.</p> <p>“These multiple threats are interacting in ways that we can predict, but there’s probably ways that we can’t predict that are going to negatively impact them as well.”</p> <h2>The bad list: more Australian icons added or re-graded in 2022</h2> <p>The greater glider isn’t alone in being uplisted on the nation’s threatened species register in 2022.</p> <p>Populations of the iconic koala (Phascolarctos cinereus) living in Queensland, New South Wales and the Australian Capital Territory were notably transferred from vulnerable to endangered status <a href="https://cosmosmagazine.com/nature/animals/explainer-koalas-endangered-nsw-qld-act/" target="_blank" rel="noreferrer noopener">earlier this year.</a> The yellow-bellied glider (Petaurus australis australis) and long-nosed potoroo (Potorous tridactylus trisulcatus) were listed as vulnerable in March.</p> <p>And many species other than mammals have been added to the list in 2022.</p> <p>Watson’s (Litoria watsoni) and Littlejohn’s tree frog (L. littlejohni), the gang-gang cockatoo (Callocephalon fimbriatum) and the South Australian Bassian thrush (Zoothera lunulata halmaturina) have been either added or uplisted to endangered, while the pilotbird (Pycnoptilus floccosus) was added as vulnerable.</p> <p>The work to protect animal species from spiraling further towards extinction is a difficult business at the best of times. Triumphs are rare.</p> <p>One of note is Zoos Victoria’s 33-year-old captive breeding program for eastern barred bandicoots (Perameles gunnii), which was retired in 2021 when the species – previously extinct in the wild – was downlisted to endangered. The species is now regenerating itself in specially fenced, predator free release sites across Victoria.</p> <p>For Zoos Victoria reproductive biologist Dr Marissa Parrot, the success of the bandicoot program was a career high point. But alongside these all-too-rare moments of success are declines in other species.</p> <p>“It’s such an amazing feeling to know that you’ve made a difference to a species… but it’s just one of thousands that do need help,” Parrott says. “When an animal is added to the endangered species list, they’re going to hopefully get more focus and more funding, and they need that long-term care.</p> <p>“But it also means that they’ve got to the point where they need to be added to an endangered list, and that’s quite devastating.”</p> <p>Parrott believes that improving public knowledge of both the existence of species and the threats that exist in the wild may improve outcomes for many animals.</p> <p>That knowledge-building can extend to people taking individual action – such as providing suitable food trees to support endangered animals that lose habitat, participation in citizen science programs or even turning outdoor lights off to support threatened moths.</p> <p>While the uplisting of species like the greater glider is a troubling event, Parrott say it can serve to draw people’s attention to the challenges confronting lesser-known animals.</p> <p>“Animals like the greater glider are beautiful, and they’re fluffy, and they can really grab people’s attention,” she says. “It’s great that they’re getting that attention, but we also have many species no one’s ever heard of, like the pookila (New Holland mouse), and the <a href="https://cosmosmagazine.com/australia/missing-the-bogong-moth/" target="_blank" rel="noreferrer noopener" data-type="URL" data-id="https://cosmosmagazine.com/australia/missing-the-bogong-moth/">bogong moth</a>, which is also a tiny little animal, but an amazing species.</p> <p>“Just last week I’ve seen gang gang cockatoos and grey-headed flying foxes in my own suburb – showing that these endangered species that are in trouble are actually around us [is important].”</p> <h2>Common causes and solutions for endangerment</h2> <p>The challenges confronting greater gliders are shared by these other, less prominent animals.</p> <p>While addressing climate change requires largescale transformation across society, there are other actions that can be implemented to provide more immediate relief for native species.</p> <p>Government conservation advice provided for all animals added or uplisted so far in 2022 notes land and vegetation clearing as a survival threat. For gliders, it poses a catastrophic risk.</p> <p>That’s why moving the forestry industry to an entirely plantation-based sector is a critical solution Lindenmayer believes needs to be implemented, and soon.</p> <p>“It’s time to exit native forest logging,” he says. “The Western Australians have done this: on the 31st of December 2023, [WA] will no longer be logging native forests.</p> <p>“Victoria needs to do that at the same time, so does New South Wales. It’s really important that we tackle that issue, which renders huge areas of forest unsuitable for animals like greater gliders, either permanently or for periods of up to 200 years.”</p> <p>Lindenmayer also points to non-forestry land clearing and coal mine construction in the eastern states as adding pressure to threatened forest-dwellers. But he also wants to see the government to take biodiversity seriously.</p> <p>“The federal minister can actually get involved in this seriously and not unravel, but improve, environmental laws, to make sure that more biodiversity is not lost. That’s critical.”</p> <p>Australia <a href="https://www.pnas.org/doi/10.1073/pnas.1417301112" target="_blank" rel="noreferrer noopener">accounts for 35%</a> of global modern mammal extinctions.

The scientific way to split your Oreos

<p>How do you eat your Oreos?</p> <p>Perhaps you twist the top layer, separating the cookie into two parts, and then eat them one by one. Alternatively, do you dunk the biscuit into milk to soften it just the right amount? Or maybe you just shove the entire thing in your mouth, all for efficiency of course.</p> <p>Snacking on an Oreo while testing its mechanical properties in the lab is apparently a legitimate methodology of research, according to a team of <a href="https://cosmosmagazine.com/science/physics/yeast-free-pizza-dough-fluid-dynamics/" target="_blank" rel="noreferrer noopener">rheologists </a>– physicists who study complex fluids – from Massachusetts Institute of Technology in the US.</p> <p>In a cookie-breaking <a href="https://aip.scitation.org/doi/full/10.1063/5.0085362" target="_blank" rel="noreferrer noopener">new study</a>, the authors have introduced an emerging field called “Oreology”, derived from the Nabisco Oreo for cookie and the Greek rheo logia for “flow study”. It’s the study of the flow and fracture of sandwich cookies and the research has been published in the journal Physics of Fluids.</p> <p>Oreo creme is a member of the class of flowable soft solids known as “yield stress fluids,” which are fluids that act as soft solids when undisturbed and only flow under a sufficiently large amount of applied stress.</p> <p>The researchers characterised the flow and fracture of Oreos, finding that the creme – which they’ve found is “mushy” in rheological texture – tends to stick to just one side of the cookie.</p> <p>“Rheology can be used to measure the texture of food depending on the failure stresses and strains,” says first author Crystal Owens, a graduate student in the Department of Mechanical Engineering at MIT. “We were able to characterise Oreo creme as quantitatively mushy.”</p> <p>The team used a laboratory rheometer – an instrument which characterises the flow of a substance in response to forces – to measure the fail mechanics of an Oreo’s filling. The rheometer fixed one side of the cookie in place and carefully twisted the other until the filling failed and the cookie broke apart, after which the amount of creme on each wafer could be determined by visual inspection.</p> <p>“I had in my mind that if you twist the Oreos perfectly, you should split the creme perfectly in the middle,” says Owens. “But what actually happens is the creme almost always comes off of one side.”</p> <p>In fact, nearly all of the creme (95%) remained on just one of the biscuits after breaking, and it seems that the production process is the likely cause. Within the boxes tested, 80% of cookies had creme–heavy sides oriented uniformly in one direction, rather than 50% as would be expected from random chance.</p> <p>In a thorough investigation of this phenomenon, the rheologists also tested the influence of rotation rate, amount of creme, and flavour on the post-mortem creme distribution.</p> <p>After being dipped in milk, the Oreos degraded quickly, crumbling after about 60 seconds. Flavour and filling seemed to have little effect on the cookie mechanics but breaking the cookies apart cleanly did depend on the rotation rate.</p> <p>“If you try to twist the Oreos faster, it will actually take more strain and more stress to break them,” Owens advises. “So, maybe this is a lesson for people who are stressed and desperate to open their cookies.</p> <p>“It’ll be easier if you do it a little bit slower.”</p> <p>The team encourages further contributions to this emerging field of study but acknowledges the fact that a laboratory rheometer is not widely accessible.</p> <p>But the researchers have come up with a way to overcome this hurdle, thanks to a design for an open–source 3D–printed “Oreometer” – a rheometer specially made for twisting Oreos – for use in higher-precision home studies.</p> <p>Powered by rubber bands and coins, the team hopes to encourage educators and Oreo enthusiasts to continue studying the cookies and learning about rheology.</p> <p>“One of the main things we can do with the Oreometer is develop an at-home education and self-discovery plan, where you teach people about basic fluid properties like shear strain and stress,” concludes author Max Fan, an undergraduate student at MIT.</p> <p>This article originally appeared in <a href="https://cosmosmagazine.com/science/engineering/fluid-physics-twisting-oreo/" target="_blank" rel="noopener">Cosmos Magazine</a>. </p> <p><em>Image: Getty</em></p>

Art inspires the magic Rubik's Cube

<p>The joy puzzle lovers derive from solving a good puzzle is matched only by the frustration felt by those of us who are not good solvers. 2015 marked the 40th anniversary of the patenting of perhaps the greatest – and most difficult – puzzle of the 20th century, the Rubik’s Cube.</p> <p>In 1974, Ernő Rubik was living in Budapest and teaching design courses at the Academy of Applied Arts and Crafts. The cube’s beginnings are unclear, but some reports state a project given to his students inspired Rubik’s prototype which was then refined over about six weeks. He created a plastic cube with six different colours, one for each face, with each face divided into a 3×3 grid. The beauty of it was that each face could turn independently thanks to an internal mechanism of 21 parts moving on curved tracks.</p> <p>He had considered the cube to be primarily a work of art, until he scrambled the colours. Realising how difficult it was to restore each face to a single colour, Rubik discovered he’d created a puzzle. It took him more than a month to work out how to solve it. Initially, Rubik wasn’t even sure a solution was possible. Eventually he hit upon the idea all modern solutions are based upon – certain moves exist that will exchange pairs or triplets of edge or corner pieces without disturbing the remainder of the cube. This convinced him to go ahead with his marketing plans. In 1977 production began within Hungary.</p> <p>Puzzle crazes have periodically captivated the world since the early 1800s. The “Chinese Tangram” puzzle was wildly popular from about 1815 until the 1820s, with plastic sets still available. In 1880 the “15 Puzzle” was all the rage in Boston and eventually spread to Europe before fizzling out after about six months. Rubik played with the 15 puzzle as a child and says he was possibly inspired by it. More recently, Sudoku went from an obscure game to a multi-million dollar industry. But none of these puzzles captured the world’s attention like the Rubik’s Cube.</p> <p>Rubik’s original cube is at once elegant and fiendish.</p> <p>Rubik called it the “Magic Cube”. The first run of 5000 sold out in a few months. In 1978 the cube was a hit at the International Congress of Mathematicians and over the next several years won awards at European toy fairs. By 1980, the Ideal Toy company in the US was marketing the puzzle as “Rubik’s Cube”. It sold about 4.5 million by the year’s end. In 1981 numbers were approaching 80 million units worldwide.</p> <p>By the mid-1980s the craze had passed. The cube inspired follow-up puzzles such as the 4×4 “Rubik’s Revenge” and the 5×5 “Professor’s Cube”. These days, models of 6×6, 7×7 and even higher-order cubes can be found in puzzle stores. Computer simulations of cubes up to 100×100 are available online.</p> <p>Rubik’s original cube is at once elegant and fiendish. Puzzle expert Jerry Slocum says rotational cube puzzles are among the most difficult of all manipulative puzzles. On the standard 3×3 cube there are 43,252,003,274,489,856,000 possible arrangements.</p> <p>In 1978, while the cube was still an underground success, physicist Roger Penrose and mathematician John Conway were demonstrating solutions. Conway was said to be able to solve the cube in around four minutes without consulting notes. In 1979 David Singmaster offered a guide to the perplexed with his Notes on the Magic Cube. It led to a popular standardised notation for solving the cube which survives today. Up, Down, Front, Back, Left and Right faces are represented by U, D, F, B, L and R. A sequence to manoeuvre a corner piece into position might be written out as: R U R`. This corresponds to a clockwise twist of the right face, followed by a clockwise twist of the up face, and finally a counter-clockwise twist of the right face. The accent mark denotes a counter-clockwise twist. Although these solutions appear daunting, with a cube and instructions in hand most readers will be able to solve the puzzle in half an hour or so. Practice will soon get your times down to five to 10 minutes.</p> <p>Using such algorithms, competitors have reduced the solution time to under a minute.

Peer pressure driving sustainable diets

<p><em>Image: Getty</em></p> <div> <div class="copy"> <p>People find it notoriously difficult to change eating habits to improve their own health, let alone the planet’s.</p> <p>Now European researchers who explored factors that might motivate shifts to more sustainable diets are suggesting that social norms and self-efficacy are the most important.</p> <p>The work by Sibel Eker and Michael Obersteiner, from the International Institute for Applied Systems Analysis in Austria, and Gerhard Reese, from Germany’s University of Koblenz-Landau, supports evidence that peer group values are more powerful than scientific facts in shaping people’s beliefs and actions about climate change.</p> <p><span style="font-family: inherit;">Their findings are presented in a paper in the journal Nature Sustainability.</span></p> <p><span style="font-family: inherit;">The study was motivated by increasing calls for people to adopt plant-based diets as part of radical shifts needed to address the destructive impact of current farming practices on the environment.</span></p> <p><span style="font-family: inherit;">A key target is red meat, which vastly exceeds other food sources in terms of its land use, irrigation and greenhouse gas emissions, and is unsustainable in the face of population growth and climate change.</span></p> <p><span style="font-family: inherit;">Red meat also has been associated with chronic health conditions, including diabetes, heart disease and some cancers.</span></p> <p><span style="font-family: inherit;">On this front alone, calculations suggest that if, on average, the world adopted a flexitarian diet (one portion of red meat per week), it could potentially prevent more than 10 million deaths each year.</span></p> <p><span style="font-family: inherit;">Eker wondered if such “ambitious scenarios” were attainable.</span></p> <p><span style="font-family: inherit;">“I was observing my social network and society,” she says, “like more and more people being meat-reducers, new vegetarian restaurants in urban areas, and it </span>made me curious<span style="font-family: inherit;"> about where these dynamics could lead.”</span></p> <p><span style="font-family: inherit;">Although many people are reducing their meat intake in several countries, widespread resistance means that global levels needed to translate into environmental gains are still beyond reach. </span></p> <p><span style="font-family: inherit;">To explore how pervasive behavioural changes in meat consumption might be achieved, Eker and colleagues used an integrated assessment model to simulate population dynamics.</span></p> <p>Based on prominent psychological theories on environmental action, combined with models from management science, it includes income, social norms, climate risk perception, health risk perception, self-efficacy and response efficacy (belief that one’s actions can make a difference), as well as age, gender and education level.</p> <p>They simulated the model 10,000 times to find the optimal outcome.</p> <p>“This was an exploratory modelling study,” explains Eker, “meaning that we used the model as a platform to experiment with different scenarios to find the most important drivers of diet shifts.”</p> <p>Although she expected concern about health risks to be more important, Eker was not surprised that social norms – unwritten rules of behaviour considered acceptable in a group or society – were a leading motivator of diet change, because they create a strong, positive feedback loop, she says.</p> <p>Put differently, “As there are more vegetarians around, visibility of the phenomenon increases, therefore adoption increases”.</p> <p>The other key driver was self-efficacy, particularly in females, referring to perceived control over one’s behaviour and ability to change.</p> <p>Results showed that this model would yield the most rapid behaviour changes for people aged 15 to 44 years, even when their adoption of vegetarian diets is low.</p> <p>But even if 40% of the population became vegetarian, the model predicted that the environmental benefits may not be fully realised if everyone else continues their current meat consumption, suggesting that change requires a population-wide shift in eating patterns.</p> <p>The researchers conclude that their findings demonstrate the importance of factoring human behaviour into climate change mitigation efforts and suggest that future research also account for variations in cultural attitudes and world views.</p> <p>“We can use models to explore the social and behavioural aspects of climate change and sustainability problems in the same way as we explore the economic and environmental dimensions of our world,” says Eker.</p> <p>This could provide a better understanding of how to motivate the lifestyle changes that are essential to address the predicaments facing the planet.</p> <div class="newsletter-box"> <div

Could Viagra help prevent Alzheimer’s disease?

<h1><span style="font-size: 14px;">Insurance shows a link between Viagra prescription and a lower chance of the disease. </span></h1> <div class="copy"> <p>Viagra is used by millions of people each year to treat erectile dysfunction. But new research shows that it might not just be helpful in the bedroom – there’s a suggestion that Viagra may also help to prevent Alzheimer’s disease. Insurance shows a link between Viagra prescription and a lower chance of the disease. </p> <p>Despite what it’s best known for, sildenafil – marketed as Viagra – isn’t a one-trick pony. It was <a rel="noreferrer noopener" href="https://cosmosmagazine.com/science/biology/how-i-discovered-viagra/" target="_blank">originally developed to treat angina</a> – although it didn’t make it through trials – and there’s some evidence it could <a rel="noopener" href="https://www.pasteur.fr/en/viagra-prevent-transmission-malaria-parasite" target="_blank">help </a><a rel="noreferrer noopener" href="https://www.pasteur.fr/en/viagra-prevent-transmission-malaria-parasite" target="_blank">t</a><a rel="noopener" href="https://www.pasteur.fr/en/viagra-prevent-transmission-malaria-parasite" target="_blank">reat malaria</a>. Tadalafil, a similar drug to Viagra, <a rel="noreferrer noopener" href="https://cosmosmagazine.com/health/medicine/sex-med-looks-promising-as-heart-failure-drug/" target="_blank">has been proposed</a> as a heart failure treatment.</p> <p>A <a rel="noreferrer noopener" href="https://doi.org/10.1038/s43587-021-00138-z" target="_blank">paper</a> in <em>Nature Aging </em>has expanded its potential further, using records from insurance claims to examine the link between Viagra and Alzheimer’s disease.</p> <p>The researchers, who are based in the US, examined the insurance records of 7.23 million people, alongside genetic and other biological data. They looked through the data to pull out indicators of Alzheimer’s disease, and then examined the relationship between these indicators and over 1,600 prescribed medicinal drugs.</p> <p>Viagra had the highest link to lower chance of Alzheimer’s, with its prescription being associated with a 69% reduced risk of the disease.</p> <p>The researchers point out that while this link is significant, it doesn’t establish causality: it may be that Viagra prevents Alzheimer’s, or it may be that people who have fewer biological precursors to Alzheimer’s are also more likely to receive a Viagra prescription.</p> <p>There could also be other confounding factors at play. Sildenafil, for instance, is more likely to be prescribed to wealthy people, and wealthy people are also less likely to get Alzheimer’s disease. The sample size of Viagra users was also – unsurprisingly – mostly male.</p> <p>“Taken together, the association between sildenafil usage and decreased incidence of AD [Alzheimer’s disease] does not establish causality or its direction,” write the researchers in their paper.</p> <p>“Our results therefore warrant rigorous clinical trial testing of the treatment efficacy of sildenafil in patients with AD, inclusive of both sexes and controlled by placebo.”</p> <!-- Start of tracking content syndication.

Food can play a part of the colour of your poo and pee

<h1>Optimal pee and poo colour for your health</h1> <h2>Food, medications and illnesses can all play a part.</h2> <div class="copy"> <p>Out of the blue I passed bright red pee. I freaked, thinking it was a sign of terminal disease. Then I remembered the roasted beetroot tarts served at the party the night before – so delicious I’d eaten three!</p> <p>Beetroot, artificial colours, vitamin supplements and medications can change the colour of your urine or bowel motions. Knowing which colour changes are due to food or medicines can save you worry, or provide an early alert to get to the doctor.</p> <h2>Beeturia</h2> <p>Beeturia is the term for passing red urine after eating beetroot. The red colour comes from a pigment called betalain, also in some flower petals, fruit, leaves, stems and roots. Concentrated beetroot extract, called Beet Red or additive number 162 on food labels, can be added to “pink” foods, such as ice-cream.</p> <p>Whether betalain turns your pee red or not depends on the type of beetroot, amount eaten and how it’s prepared, because betalain is destroyed by heat, light and acid.</p> <p>How much betalain enters your digestive tract depends on stomach acid and stomach emptying rate (people taking medications to reduce stomach acid may be prone to beeturia). Once in the blood stream, betalain pigments are filtered out by the kidneys. Most is eliminated two to eight hours after eating.</p> <p>Persistent red urine can be due to blood loss, infection, enlarged prostate, cancer, cysts, kidney stones or after a long-distance run. If you see red and have not been eating beetroot, see your doctor.</p> <h2>What should your pee look like?</h2> <p>Normal pee should be the colour of straw. If your pee is so colourless that it looks like water, you probably drank more than you needed.</p> <p>Very dark yellow pee usually means you are a bit dehydrated and need to drink more water.</p> <p>Compare your pee colour to the Cleveland Clinic’s scale below.</p> <span class="attribution"><span class="source">Courtesy Cleveland Clinic</span></span> <h2>Strange pee colours due to food, drugs or disease</h2> <p>Pee the colour of syrup or molasses needs medical investigation. While it could be due to extreme dehydration, it can be a sign of liver diseases such as hepatitis and cirrhosis, where a build up of bilirubin spills into your pee. Bilirubin is a breakdown product of red blood cells; it’s also responsible for poo’s normal brown colour.</p> <p>Pee can turn bright orange or yellow when taking beta-carotene or vitamin B supplements, especially large doses of riboflavin (vitamin B2). These supplements are water soluble. What your body can’t use or store gets filtered out via your kidneys and into pee.</p> <p>Medications including phenazopyridine (for urinary tract infections), rifampin (antibiotic for treating tuberculosis and Legionnaire’s disease), warfarin (blood thinner) and some laxatives can also change pee colour.</p> <p>If you pass blue or green pee, it’s most likely due to food colouring or methylene blue used in some diagnostic test procedures and some drugs.</p> <p>But a range of medications can also trigger blue or green urine. These include antihistamines, anti-inflammatories, antibacterials, antidepressants, some nausea drugs or those for reducing stomach acid.</p> <p>Rare genetic conditions Hartnup disease and Blue diaper syndrome cause blue-green urine. So see your doctor if it persists or it happens in an infant.</p> <p>You should never see purple pee, but hospital staff might. “Purple urine bag” syndrome happens in patients with catheters and infections or complications. The catheter or bag turns purple due to a chemical reaction between protein breakdown products in urine and the plastic.</p> <p>Occasionally, pee can be frothy. It’s a normal reaction if protein intake is high and pee comes out fast. It is more likely if you consume protein powders or protein supplements. Excess protein can’t be stored in the body so the nitrogen component (responsible for the froth) gets removed and the kidneys excrete it as urea.</p> <p>See your doctor if the frothiness doesn’t go away or gets worse, as protein can leak into pee if you have kidney disease.</p> <h2>Poo colours of the rainbow</h2> <p>Normal poo colour ranges from light yellow to brown to black. The colour is due to a mix of bile, which starts off green in the gall bladder, and bilirubin a yellow breakdown product from red blood cells.</p> <p>Poo can turn green after consuming food and drink containing blue or green food colouring, or if food travels too fast through the gut and some bile is still present.</p> <p>Poo that is yellow, greasy and smells really bad signals food malabsorption. If this colour is associated with weight loss in an adult or poor growth in a child, see a doctor to rule out gut infections such as giardia or medical conditions like coeliac disease.</p> <p>Very pale or clay-coloured poo can happen when taking some anti-diarrhoeal medications, or when digestive problems affect the liver, gut, pancreas or gall bladder.</p> <p>At the other extreme of the colour spectrum, black poo could be a serious medical issue due to bleeding in the stomach or upper gut. Or it could be a harmless side-effect from taking iron supplements, or eating lots of licorice.</p> <p>Red poo can also be a serious medical issue due to bleeding in the lower gut, or from haemorrhoids, or harmless after having large amounts of red food colouring.</p> <p>If you don’t know what colour your pee or poo is, take a look. If you see a colour that’s out of the ordinary and you haven’t eaten anything unusual, take a picture and make an appointment to show your GP.</p> <p>Clare Collins, Professor in Nutrition and Dietetics, <em>University of Newcastle</em>; Kristine Pezdirc, Research Associate | Post-doctoral Researcher, <em>University of Newcastle</em>, and Megan Rollo, Postdoctoral Research Fellow, Nutrition &amp; Dietetics, <em>University of Newcastle</em></p> <!-- Start of tracking content syndication.

Home gardens vital for pollinators

<h2><strong style="font-size: 14px;">They provide a rich and diverse nectar source, study finds.</strong></h2> <div class="copy"> <p>Urban areas are a surprisingly rich food reservoir for pollinating insects such as bees and wasps, according to a UK study <a rel="noreferrer noopener" href="https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2745.13598" target="_blank">published</a> in the <em>Journal of Ecology</em>.</p> <p>Home gardens are particularly important, the study found, accounting for 85% of the nectar – sugar-rich liquid that provides pollinators with energy – within towns and cities and the most diverse supply overall.</p> <p>Results showed that just three gardens generated on average around a teaspoon of the liquid gold – enough to attract and fuel thousands of pollinators.</p> <p>“This means that towns and cities could be hotspots of diversity of food – important for feeding many different types of pollinators and giving them a balanced diet,” says lead author Nicholas Tew, from the University of Bristol.</p> <p>“The actions of individual gardeners are crucial,” he adds. “Garden nectar provides the vast majority of all. This gives everyone a chance to help pollinator conservation on their doorstep.”</p> <p><a rel="noreferrer noopener" href="https://www.pollinator.org/pollination" target="_blank">Pollinators</a> include bees, wasps, butterflies, moths, bats and beetles. They are critical for ecosystems and agriculture as most plant species need them to reproduce, and <a rel="noreferrer noopener" href="https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.453.4134&amp;rep=rep1&amp;type=pdf" target="_blank">research suggests</a> their survival relies especially on the diversity of flowering plants.</p> <p>To explore how our sprawling urban areas could support them, Tew’s research group previously led the <a rel="noreferrer noopener" href="http://www.bristol.ac.uk/biology/research/ecological/community/pollinators/" target="_blank">Urban Pollinators Project</a> in collaboration with other universities. They found that cities and gardens – community and private – are vital for pollinators, leading them to question how to quantify and harness this resource.</p> <p>“The gap in our knowledge was how much nectar and pollen urban areas produce and how this compares with the countryside,” Tew explains, “important information if we want to understand how important our towns and cities can be for pollinator conservation and how best to manage them.”</p> <p>So, for the current study, Tew and colleagues measured the supply of nectar in urban areas, farmland and nature reserve landscapes, and then within four towns and cities (Bristol, Edinburgh, Leeds and Reading) to determine how much nectar different land uses produce.</p> <p>To do this, they extracted nectar from more than 3000 flowers comprising nearly 200 plant species using a fine glass tube and quantified it using a refractometer, an instrument that measures how much light refracts when passing through a solution.</p> <p>Then they sourced nectar measurements from other published studies and combined the nectar-per-flower values with numbers of flowers from each species in different habitats as previously measured by the group.</p> <p>Overall, nectar quantity per unit area was similar in urban, farmland and nature reserve landscapes. But urban nectar supply was most diverse, as it was produced by more flowering plant species. And while private gardens supplied similarly large amounts per unit as allotments, they covered more land – nearly a third of towns and cities.</p> <p>It’s important to note the findings are specific to the UK, and maybe parts of western Europe, Tew says. Most urban nectar comes from ornamental species that are not native, which can be attractive to generalist pollinators but may not benefit specialist species that feed from selective native flower species.</p> <p>Thus private gardens in other regions might have different benefits. Australia, for instance, has more endemic species and specialist pollinators than the UK, so while non-natives would still provide some benefit, natives may be more important overall.</p> <p>Most recommendations for attracting pollinators in Australia include supporting native bees and other local specialists. Suggestions include planting more native species and providing <a rel="noreferrer noopener" href="http://www.australianenvironmentaleducation.com.au/australian-animals/australian-pollinator-week/" target="_blank">accommodation</a> for native bees, most of which are solitary species – unlike the familiar, colonial European honeybee.</p> <p>But in general, Tew says home gardeners can all support biodiversity with some key strategies, especially planting as many nectar-rich flowering plants as possible and different species that ensure flowers all year round.</p> <p>Other <a rel="noreferrer noopener" href="https://www.rhs.org.uk/science/conservation-biodiversity/wildlife/plants-for-pollinators" target="_blank">recommendations</a> include mowing the lawn less often to let dandelions, clovers and other plants flower, avoiding <a rel="noreferrer noopener" href="https://cosmosmagazine.com/biology/scientists-call-for-urgent-action-on-bee-killing-insecticides/" target="_blank">pesticides</a> and never spraying open flowers, and covering as much garden area as possible in flowery borders and natural lawns.</p> <!-- Start of tracking content syndication.

Four artists explain how science informs and inspires their work

<p>“The greatest scientists are artists as well,” said Albert Einstein. For as long as artistic expression has existed, it has benefited from interplay with scientific principles – be it experimentation with new materials or the discovery of techniques to render different perspectives. Likewise, art has long contributed to the work and communication of science.</p> <p>We asked four outstanding artists to comment on their work and its relationship to science. “Science is my muse,” replied Xavier Cortada, who marked the discovery of the ‘God particle’ with a set of triumphal banners. The same can be said for the other three: Suzanne Anker renders small worlds in petri dishes, Lia Halloran explores serendipity in science, and Daniel Zeller translates images from alien realms in his own artistic language.</p> <p>Credit: Raul Valverde</p> <p><strong>Suzanne Anker</strong></p> <p><img style="width: 496px; height: 496px;" src="https://oversixtydev.blob.core.windows.net/media/7843784/art-suzanne-anker-um.jpg" alt="" data-udi="umb://media/b5d9c04404f441f7a95f03be92b1a842" /></p> <p>Employed as a container for working with fungi, bacteria and even embryos, the glass dish named after bacteriologist Jules Petri is not only a fundamental of laboratory research: it has become a cultural icon.</p> <p>In my Remote Sensing series I use the Petri dish to juxtapose microscopic and macroscopic worlds. The title refers to new digital technologies that can picture places too toxic or inaccessible to visit.</p> <p>The fabrication of this piece began with 2D digital photographs, which were then converted into 3D virtual models. This petri dish with its luxuriant growth emerged from the 3D printer.</p> <p>These micro-landscapes offer the viewer a top-down topographic effect assembled by zeros and ones. Each configuration of these works takes the geometry of a circle, inspired by the Petri dish, and crosses the divide between the disciplines of art and science.</p> <p>The ‘bio art’ of Suzanne Anker explores the intersection of art and the biological sciences. Based in New York, Anker works in a variety of traditional and experimental mediums ranging from digital sculpture and installation to large-scale photography and plants grown under LED lights. Her work has been exhibited at the J. Paul Getty Museum in Los Angeles, the Pera Museum in Istanbul, and the International Biennial of Contemporary Art of Cartagena de Indias, Colombia. Anker is co-author of The Molecular Gaze: Art in the Genetic Age (2004) and co-editor of Visual Culture and Bioscience (2008). </p> <p><a href="http://www.suzanneanker.com">www.suzanneanker.com</a></p> <p>Credit: Lia Halloran</p> <p><strong>Lia Halloran</strong></p> <p><img style="width: 500px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7843785/art-lia-halloran-um.jpg" alt="" data-udi="umb://media/b408465517604d788b927db09d523746" /></p> <p>The 18th-century French astronomer Charles Messier set his telescopic sights on the grand prize of finding a lonely, wandering comet. He ended up amassing an astronomical inventory filled with galaxies, clusters and nebulae. A catalogue of 110 objects is credited to his journals and drawings.</p> <p>Deep Sky Companion is a series of 110 pairs of paintings and photographs of night sky objects drawn from the Messier catalogue.</p> <p>These works are about discovery and all the things we find when we are not seeking them. It relates to my own challenging first stabs at observing the night sky. In college I was given a small Celestron telescope for Christmas. Observing the Orion Nebula and nearby galaxies seemed to create a fold in time between Messier and myself.</p> <p>I would imagine his sessions observing through his telescope and the drawings he made to classify the natural world and make sense of the unknown above him.</p> <p>Each painting in the Deep Sky Companion series was created in ink on semi-transparent paper, which was then used as a negative to create the positive photographic equivalent using standard black-and-white darkroom printing. This process connects to the historical drawings by Messier, here redrawn and then turned back into positives through a photographic process mimicking early glass-plate astrophotography.</p> <p>Lia Halloran is an artist and academic based in Los Angeles. At Chapman University, in California’s Orange County, she teaches painting as well as courses that explore the intersection of art and science. Her art often makes use of scientific concepts and explores how perception, time and scale inform the human desire to understand the world, and our emotional and psychological place within it. She has held solo exhibitions in New York, Miami, Boston, Los Angeles, London, Vienna and Florence.

(Cassini’s 20-year mission ended in September 2017 when it crashed into Saturn.) There are obvious reasons Titan is so appealing: Saturn’s largest moon has an atmosphere, deserts and seas – it is an alien world with some characteristics we can relate to.</p> <p>The probe generated so much fascinating source material it was difficult to choose any single viewpoint, but there was something particularly intriguing about the image of Titan I finally settled on. Greyscale imagery naturally lends itself to broad interpretation, and the radar-mapping method suited my curiosity and my process; it seems to relay its subject as somehow simultaneously familiar and completely alien. Titan’s surface became a scaffold on which I could build and explore. The relative ambiguity of the source image allowed me wide latitude to interpret the moon as a stand-in for any not-yet-discovered world or landscape, while still allowing it to be grounded in the recognisable projection of topography.</p> <p>The Cassini mission was a truly amazing foray into the unknown. We are greatly enriched by the knowledge it collected. My work is but a humble homage to our immediate neighbourhood – once so far away and now a little bit closer – and to what is yet to be discovered on many frontiers.</p> <p>Daniel Zeller is an illustrator and painter based in New York.

These high-energy collisions make new particles and new mass.</p> <p>The LHC’s detectors did not directly measure the Higgs.</p> <p>They measured the paths taken by the photons, quarks and electrons created in the collisions. The curvature of the paths  revealed the charge and momentum of the particles, and the size of the signal their energy. The data told scientists there was another particle – the Higgs boson – produced in the collisions.</p> <p>Let me tell you why these experiments were so important. When physicists first came up with the Standard Model of physics, a theory to describe the forces and particles of nature, they couldn’t figure out how to give those particles mass.</p> <p>This was quite a problem, because particles with no mass would move at the speed of light and be unable to slow down enough to form atoms. Without atoms the universe would be very different.</p> <p>In the 1960s British physicist Peter Higgs and others independently came up with a theory to solve that problem. Just as marine creatures move in water, all particles in the universe move in a fundamental energy field – now commonly known as the Higgs field. As particles travel through the field, their intrinsic properties generate more or less mass – much as the properties of an animal create different degrees of drag as it moves through water.  Think of a barracuda and a manatee. The sleeker barracuda is going to move faster.</p> <p>Mathematically, the theory required the existence of a particle representing the ‘excited state’ of the field. This new particle – dubbed the Higgs boson – would be to the Higgs field what photons are to the electromagnetic field. Finding the particle involved scientists from 182 universities and institutes in 42 countries. On 4 July 2012, half a century after it was first postulated, CERN scientists announced its discovery.</p> <p>The detection itself was intricate and multilayered, and so were the artworks I created. Stained glass references the LHC as a modern-day cathedral that helps us understand the universe and shape our new world view. The oil painting technique honours those who came before us, the repetition of motifs across the five works celebrates internationalism, and rendering the work as ‘banners’ marks this as a monumental event.</p> <p>Most importantly, the background for the banners honours the scientific collaboration. It is composed of words from the pages of 383 joint publications and the names of more than 4,000 scientists, engineers and technicians. With this piece I wanted to create art from the very words, charts, graphs and ideas of this coalition of thinkers.</p> <p>It was a supremely important moment for humanity. I wanted the art to mark that event at the exact location where the experiment took place. These five banners hang at the exact location of the LHC, where the Higgs boson was discovered. That is where a scientific theory crystallised into a proven truth.</p> <p>It is my hope these banners will inspire future generations of physicists to continue to move humanity forward.</p> <p>Xavier Cortada is a painter based in Miami, Florida. His art regularly involves collaboration with scientists. As well as his art installation for CERN, he has worked with a population geneticist on a project exploring our ancestral journey out of Africa 60,000 years ago, with a molecular biologist to synthesise DNA from participants visiting his museum exhibit, and with botanists on eco-art projects. He estimates his installation at the South Pole using a moving ice sheet as an instrument to mark time will be completed in 150,000 years.</p> <p><a href="http://www.cortada.com">www.cortada.com</a></p> <p><strong>Related reading:</strong></p> <ul> <li><a href="https://cosmosmagazine.com/society/when-arts-and-science-collide/">When arts and science collide</a></li> <li><a href="https://cosmosmagazine.com/biology/how-eye-disorders-may-have-influenced-the-work-of-famous-painters/">Eye disorders influence famous painters</a></li> <li><a href="https://cosmosmagazine.com/technology/sciences-war-on-art-fraud/?hilite=%27artist%27">Science’s war on art fraud</a></li> </ul> <p><a href="https://cosmosmagazine.com/people/society/four-artists-influenced-by-science/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/cosmos-editors">Cosmos</a>. </p> <p> </p>

The new stress-free way to travel

<p>Jetting off around the world is one of the most rewarding experiences but isn’t always without hassle. Endless hours can be spent comparing the best deals, organising your itinerary and selecting affordable accommodation -  it’s enough to flip a fun holiday into a scarring experience!</p> <p>However, savvy travellers are flocking to a new category of touring that takes away the burden of organising the logistics of your trip but also allows you the freedom to set your own itinerary at your own pace.</p> <p>Cosmos Lite is offering the world’s first <span style="text-decoration: underline;"><strong><a href="https://goo.gl/MuroYf">à la carte tour style</a></strong></span>, which combines the essential features of their award-winning Cosmos tours with a personalised and independent approach to daily itineraries.  </p> <p>Travellers will be able to choose a holiday package that includes city-to-city transportation, comfortable hotels and daily breakfasts.</p> <p>So, how does it allow travellers to go overseas without the headache?</p> <p><strong>1. Explore on your own when necessary</strong></p> <p>While it is a great bonding experience to travel with a group, sometimes it is valuable to also spend some time alone. Having the opportunity to take breaks from your tour group and schedule in your own enjoyment will give you the perfect opportunity to recharge and reflect on all the fun you will be having. Travelling with <a href="https://goo.gl/MuroYf"><span style="text-decoration: underline;"><strong>Cosmos Lite</strong></span></a> will allow you to have the perks of travelling with a group, such as meeting new people and greater security, but then also give you the opportunity to explore at your own pace. Breaking away from the group will give you the chance to learn how to enjoy your own company in a foreign place and also force you to get out of your comfort zone. And if you ever get a bit lonely when going solo, you can return to your tour group.</p> <p><strong>2. Freedom to tailor itineraries</strong></p> <p>Cosmos Lite provides a blank canvas for travellers at each destination so that they can customise their experience. Your Tour Director will point out the best sightseeing, dining and entertainment options at each location, so you will never be without a good recommendation.</p> <p>Those who are looking to find trusted local information will also have access to the CosmosGO mobile app at their fingertips. For those who are wanting to spontaneously spend their time completing more activities than they originally thought, they will be able to purchase them on the go with optional excursions.</p> <p>Cosmos Lite excursions typically start later than normal tours, so you can choose to spend your morning however you like – whether you want to get some extra hours of shut eye or set out for an adventure. You can also select solo or group outings, depending on your personal preference.</p> <p><strong>3. Don’t worry about the stressful details</strong></p> <p>One of the painpoints of travelling is making sure you are doing sufficient research to get your hands on the best bargain and avoid getting scammed. Cosmos Lite takes care of city-to-city transport, hotels and daily breakfasts, so you can spend your time and energy on planning the more exciting aspects of your holiday.</p> <p>Cosmos Lite offers travellers transport in private deluxe motorcoaches between destinations with free Wi-Fi and air conditioning. The tour will include clean, comfortable and attractive hotels that offer customers the most for their money.</p> <p>Travellers will also have the most important meal of the day covered in the tour price so that you can start every morning energised with a full stomach.</p> <p>What are your tips for stress-free travel?
