Re-greening: can Louisville plant its way out of a heat emergency?

The Kentucky city is the fastest-warming urban heat island in the US and as its temperature has risen, its tree cover has plummeted There are parts of Louisville, Kentucky, that are enveloped in green, where towering trees arc over broad avenues and walkers, joggers and bikers enjoy beautiful parks designed by Frederick Law Olmsted, the man who drew up plans for Manhattans Central Park. Even on the hottest days of summer, these neighbourhoods feel comparatively refreshing next to the more sun-baked quarters of the city, where shade is often an unavailable commodity on the street. Cities are their own climates, often hotter than their surroundings due to the way surfaces like asphalt trap heat even as cars and buildings exude …

Scientists develop slippery toilet coating to stop poo sticking

Spray-on surface could prevent bacteria building up and reduce household water use The toilet brush need never leave its holder again. Scientists have created a super-slippery coating that helps usher excrement on its way without leaving traces behind. The spray-on coating, which is slipperier than Teflon, reduces adhesion of even tenacious faeces by up to 90%, tests suggest, so far less water is needed to flush them away and leave the toilet clean. Researchers at Penn State University believe the coating could slash Writing in the journal Nature Sustainability, Wong, who has co-founded a company to sell the coating, describes how all of the comparison surfaces displayed extreme stickiness to the faeces, while the Less coating appeared to shed its …

Observation of the Development of a Chick Embryo by Shell-Less Hatching

In this astonishing video by the Mihama Veterinary Clinic in Fukui, Japan, we observe the development of a chick embryo by shell-less hatching method. This demonstration is practiced mainly based on the scientific article written by Tahara et. al. The eggs sold in-store are usually unfertilized egg and never develop into chicks, so you don’t have to worry about an eating embryo or baby chick. However, fertilized egg may be sold in organic or natural health stores, family poultry farms, etc. where chicks can grow just same as a normal chick would.

Risks of cannabis use for mental health treatment outweigh benefits

New study shows evidence of positive outcomes is scarce while symptoms can be exacerbated The use of cannabis medicines to treat people with depression, anxiety, psychosis or other mental health issues cannot be justified because there is little evidence that they work or are safe, according to a major new study. A review of evidence from trials conducted over nearly 40 years, Photograph: PR Was this helpful? Thank you for your feedback. The authors looked for evidence of an effect of medicinal cannabinoids in trials conducted in depression, anxiety, attention-deficit hyperactivity disorder (ADHD), Tourette syndrome, post-traumatic stress disorder (PTSD) and psychosis. They found 83 studies in 3,000 people. But the evidence of a positive effect was sparse. There was, they …

Why this top federal scientist is worried about public health under Trump | Carey Gillam

The US government has become dangerously complacent about public health If you want to understand the perilous state of federal scientific research, ask Linda Birnbaum. For 40 years, Birnbaum has worked as a toxicologist for the US government, rising through the ranks to direct both the National Institute of Environmental October retirement from the institute she says she has tried to protect from the ramifications of Donald Trumps election, Birnbaum has words of warning about the dire path ahead she sees for public health. We ought to listen to what she has to say. Birnbaum fears that the US regulatory system has become too politicized, too beholden to corporate money and power, and lacks the urgency and political will needed …

Uproar after research claims red meat poses no health risk

One expert says findings by international experts represent egregious abuse of evidence New research that claims red and processed meat is probably not harmful to our health has caused controversy among experts who maintain people should cut down. The World Health Organization has classified red and processed meats as cancer-causing. Public health bodies worldwide urge people to limit their intake of red and processed meat to reduce their cancer risk. The NHS advises that people who eat 90g of meat a day equivalent to three thin slices of roast meat should cut down to 70g. Aside from public health, calls are multiplying for people to cut back on meat consumption because of the climate emergency and the greenhouse gas emissions …

Fragrance sensitivity: why perfumed products can cause profound health problems

An intolerance to manufactured scents can lead to migraines, respiratory issues and long-term sick leave. So should they be banned in public spaces? If you flew abroad this summer, you probably passed through an airports duty-free perfume section. Perhaps you paused to spritz yourself with an expensive scent you had no intention of buying, before making the obligatory trip to WH Smith for overpriced crisps and bottles of water. For most people, the wafting odours of perfume counters are not a problem. But, for some, the trip through duty free is a choking, cloying experience. Helsinki, Copenhagen among those offering perfume-free routes for passengers with fragrance sensitivities. Legislators are also responding to the need for fragrance-free public spaces: most hospitals …

Ditch your air-conditioning. You’ll be fine | Franklin Schneider

A hot room wont usually kill you, but a hot planet will. If you feel sweaty, just imagine how your grandchildren are going to feel We think of air conditioning as a first world luxury, but its really more of an American one. In Europe, fewer than 5% of households have air conditioning, article in the New York Times (for which, full disclosure, I was interviewed, though my quotes didnt make it in) pointed out something that Ive often observed anecdotally: that the perception of thermal discomfort is correlated with GDP. In other words, only rich people whine about the heat, crank the a/c, and then go on Twitter to brag about how theyre not setting foot outside. Everyone else …

The Notre Dame Fire Spread Toxic Lead Dust Over Paris

This story originally appeared on CityLab and is part of the Climate Desk collaboration. Three months after the devastating fire at Notre-Dame Cathedral in Paris, reports of a new, previously unheeded threat to local residents have emerged: lead poisoning. According to confidential documents leaked to the (paywalled) website Mediapart earlier this month and discussed across French media, locations surrounding the fire-damaged cathedral have registered levels of lead contamination ranging between 500 and 800 times the official safe level. The building’s roof and spire were clad in several hundred tons of the metal, which can be toxic if particles are inhaled or consumed, especially to children. The blaze that consumed the cathedral’s roof liquified oceans of lead and lofted a plume …

A New Approach to Treat Mental Illness: Electrical Engineering

Brain disorders impact more than 25 percent of Americans, and such disorders are projected to cost more than one trillion dollars annually by 2050. In response, the federal government launched the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) initiative in 2013 to uncover how the human brain works as an electrical machine. This group of researchers has been tasked with answering the following question: What if mental illness could be treated with electrical engineering? While the human brain contains nearly 100 billion cells that create and process electricity, human brain augmentation has largely been limited to drugs that target brain chemicals. By discovering how the brain computes, we hope scientists will be able to develop new treatments and bend the projected …

Want Your Kid to Play Pro Soccer? Sign Her Up for Basketball

The Women’s World Cup is in full swing, and today the Americans will face off against France in a battle to advance to the semifinals. This year’s American team is a strong one, both in personality (they are currently engaged in an equal-pay dispute with the US Soccer Federation) and in style—they started the tournament with a 13-0 rout over Thailand. This year’s squad is also unique because it’s the first US women’s soccer team with women who chose to skip college soccer and go straight to the pros. Mallory Pugh and Lindsey Horan were the first American women soccer players to make that decision, but they are hardly the last. This year, Olivia Moultrie became the youngest American woman …

Use of male mice skews drug research against women, study finds

Male animal bias is unjustified and can lead to drugs that work less well for women The male mind is rational and orderly while the female one is complicated and hormonal. It is a stereotype that has skewed decades of neuroscience research towards using almost exclusively male mice and other laboratory animals, according to a new study. Scientists have typically justified excluding female animals from experiments even when studying conditions that are more likely to affect women on the basis that fluctuating hormones would render the results uninterpretable. However, according to Rebecca Shansky, a neuroscientist at Northeastern University, in Boston, it is entirely unjustified by scientific evidence, which shows that, if anything, the hormones and behaviour of male rodents are …

The Apple Watch Is Now the Control Center for Your Health

This week at Apple's Worldwide Developers Conference, Apple executive Kevin Lynch announced multiple updates to WatchOS, the operating system that powers the company's smartwatch. (Voice memos, a calculator, streaming audio, oh my!) But the most telling features were the new additions to the watch's suite of health-monitoring tools. Beginning this fall, Apple Watch will track your activity trends over time, help protect your hearing by alerting you to harmful levels of ambient noise, and allow users to track their menstrual cycles. Individually, these improvements might look small or trivial. But given the watch's existing health and fitness features, this new bundle of capabilities underscores Apple’s push to make its smartwatch the control center for your personal health. Sure, calculating a …
