The climate science is clear: it’s now or never to avert catastrophe | Bill McKibben

Disastrous global heating will soon become irrevocable but despite politicians inaction millions are taking to the streets to fight the planets fever The one thing never to forget about global warming is that its a timed test. Its ignoble and dangerous to delay progress on any important issue, of course if, in 2020, America continues to ignore the healthcare needs of many of its citizens, those people will sicken, die, go bankrupt. The damage will be very real. But that damage wont make it harder, come 2021 or 2025 or 2030, to do the right thing about healthcare. appeal But the climate crisis doesnt work like that. If we dont solve it soon, we will never solve it, because we …

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 …

Oceanographer Creates Algorithm to Remove Water From Underwater Images

Coral reefs are among nature’s most complex and colourful living formations. But as any underwater photographer knows, pictures of them taken without artificial lights often come out bland and blue. Even shallow water selectively absorbs and scatters light at different wavelengths, making certain features hard to see and washing out colours—especially reds and yellows. This effect makes it difficult for coral scientists to use computer vision and machine-learning algorithms to identify, count and classify species in underwater images; they have to rely on time-consuming human evaluation instead. But a new algorithm called Sea-thru, developed by engineer and oceanographer Derya Akkaynak, removes the visual distortion caused by water from an image. The effects could be far-reaching for biologists who need to …

Seismologist Explains How To Make An Earthquake Early Warning System With Cats

The notion that animals can somehow sense an incoming earthquake long before humans has been around for centuries. In 373 BC, at the peak of the classical Greek era, a violent earthquake and subsequent tsunami destroyed and submerged the city of Helike. This city was known, ironically, as a center for worship for Poseidon – the god of the sea and earthquakes – and its loss to the murky depths just might have been the origin story to the celestelabedz But there’s another myth associated with this Greek tragedy. Apparently, 5 days before the massive earthquake struck, all the animals fled the city en masse, much to the puzzlement of the local people. Those critters knew what was coming, and got the …

UK diplomatic cables shed light on Cuba ‘sonic attacks’ scare

FoI release shows how embassy and FCO staff sought to make sense of mystery illnesses Official emails and diplomatic telegrams marked as sensitive reveal for the first time how the British government scrambled to understand a series of alleged sonic attacks on US diplomats who became ill in mysterious circumstances while on duty in Cuba. The US government ordered all non-essential staff at its embassy in Havana to return home after dozens of diplomats and family members developed headaches, dizziness and problems with balance, concentration and sleeping in a wave of illness that struck between 2016 and 2018. Many reported falling ill in their homes or hotels after hearing penetrating sounds, described variously as grinding, buffeting or cicada-like chirps. The …

Faking it: could I go from being an introvert to an extrovert in one week?

New research has found that being an extrovert makes you happier. So I spent a week attending social events to see if I could trick myself into being more naturally outgoing I was asked to torture myself for a week for this experiment. Well, not torture, but close enough for me. For a week, what Princess Diana used to do when she wanted to lose friends change her phone number. So the prospect of spending a week saying yes to every social engagement that came my way was about as appealing as a root canal treatment. But evidence shows that conquering your inner introversion can be good for your mental health. In the study of its kind, researchers at the …

Nasa’s Voyager 2 sends back its first message from interstellar space

Nasa craft is second to travel beyond heliosphere but gives most detailed data yet Twelve billion miles from Earth, there is an elusive boundary that marks the edge of the suns realm and the start of interstellar space. When Voyager 2, the longest-running space mission, crossed that frontier more than 40 years after its launch it sent a faint signal from the other side that scientists have now decoded. The Nasa craft is the second ever to more than six years behind, after taking the scenic route across the solar system and providing what remain the only close-up images of Uranus and Neptune. Now Voyager 2 has sent back the most detailed look yet at the edge of our solar …

Sea levels set to keep rising for centuries even if emissions targets met

Generations yet unborn will face rising oceans and coastal inundations into the 2300s even if governments meet climate commitments, researchers find Sea level rise is set to challenge human civilization for centuries to come, even if internationally agreed climate goals are met and planet-warming emissions are then immediately eliminated, researchers have found. The lag time between rising global temperatures and the knock-on impact of coastal inundation means that the world will be dealing with ever-rising sea levels into the 2300s, regardless of prompt action to address the climate crisis, according to the new study. Even if governments meet their commitments from the landmark 2015 Paris climate agreement, the first 15-year period of the deal will still result in enough emissions …

Strike a contrapposto pose to look more attractive, science says

Study finds pose makes waist-to-hip ratio seem lower on one side and looks more appealing Dancers do it, Instagrammers do it, even the Venus de Milo does it. When it comes to striking a pose, it seems the only way is contrapposto. Now research has shed light on why the attitude is so appealing. Experts say the pose, which involves standing with weight predominantly on one foot with a slight twist in the upper body, makes the waist-to-hip ratio appear strikingly low on one side of the body. A low waist-to-hip ratio reflecting studies have suggested the most popular imaginary women have even lower ratios in particular a very small waist a finding that might help to explain the appeal …

How vested interests tried to turn the world against climate science

For decades fossil fuel majors tried to fight the consensus just as big tobacco once disputed that smoking kills In 1998 a public relations consultant called Joe Walker wrote to the American Petroleum Institute (API), a trade association representing major fossil fuel companies, with a proposed solution to a big problem. In December the previous year, the UN had adopted the Kyoto protocol, an international treaty that committed signatory countries to reducing their greenhouse gas emissions in order to avert catastrophic climate breakdown. Reducing emissions represented a direct threat to the profits of fossil fuel companies and the API was working on an industry response. As promised, attached is the Global Climate Science Communications Plan that we developed during our …

Revealed: top UK thinktank spent decades undermining climate science

UKs Institute of Economic Affairs has links to 14 members of Boris Johnsons cabinet The UKs most influential conservative thinktank has published at least four books, as well as multiple articles and papers, over two decades suggesting manmade climate change may be uncertain or exaggerated. The Institute of Economic Affairs (IEA) has issued publications arguing climate change is either not significantly driven by human activity or will be positive. The group is one of the most politically influential thinktanks in the UK, and boasts that 14 members of Boris Johnsons cabinet, including the home secretary, foreign secretary and chancellor, have been associated with the groups past and current initiatives. Despite a Climate Accountability Institute,calculates how much carbon is emitted throughout …

Trump administration’s war on science has hit ‘crisis point’, experts warn

Nonpartisan taskforce of ex-government officials reports almost weekly violations of norms meant to safeguard objective research The treatment of science by the Trump administration has hit a crisis point where research findings are manipulated for political gain, special interests are given improper influence and scientists are targeted for ideological reasons, a nonpartisan taskforce of former government officials has warned. Safeguards meant to ensure that government research is objective and fully available to the public have been steadily weakening under recent administrations and are now at a nadir under Trump, recent sharpiegate scandal, in which Trump erroneously claimed a hurricane would hit Alabama, subsequently holding up a doctored map. Officials at the National Oceanic and Atmospheric Administration were reportedly pressured to …

Rabbits may hold key to solving mystery of human female orgasm

Study suggests climax may be an evolutionary hangover but crucial questions remain A possible explanation for one of biologys greatest mysteries, the female orgasm, has been bolstered by research showing that rabbits given antidepressants release fewer eggs during sex. The human female orgasm has long proved curious, having no obvious purpose besides being pleasurable. The scientists behind the study have previously proposed it might have its evolutionary roots in a reflex linked to the release of eggs during sex a mechanism that exists today in several animal species, including rabbits. Since humans have spontaneous ovulation, the theory goes that female orgasm may be an evolutionary hangover. They say the new experiment supports the idea. We know there is a reflex …

Elon Musk unveils Starship designed to take crew on round-trips to Mars

SpaceX spacecraft would carry passengers anywhere in solar system and land back on Earth perpendicularly Elon Musk has unveiled a SpaceX spacecraft designed to carry crew and cargo to the moon, Mars or anywhere else in the solar system and land back on Earth perpendicularly. In a live-streamed speech from SpaceXs launch facility near the southern tip of Texas, Musk said on Saturday that the space ventures Starship is expected to take off for the first time in about one or two months and reach 19,800 meters (65,000ft) before returning to Earth and landing. He said it was essential for the viability of space travel to be able to reuse spacecraft, adding it was important to take steps to extend …

Scientists invent new technology to print invisible messages

Messages can only be seen under UV light and can be erased using a hairdryer Forget lemon juice and hot irons, there is a new way to write and read invisible messages and it can be used again and again. The approach, developed by researchers in China, involves using water to print messages on paper coated with manganese-containing chemicals. The message, invisible to the naked eye, can be read by shining UV light on the paper. With the use of hot air from a hairdryer, the message can be erased and the paper reused.
