90-minute British DnaNudge COVID-19 test is accurate, Lancet study finds

A British COVID-19 test known as DnaNudge that gives results in just over an hour and which requires no laboratory was accurate in almost all cases, an academic review in the Lancet has found. Faster testing could allow more people to return to work or permit testing on entry to hospital, thus slowing a second spike in coronavirus infections. The new test, based on the design of a DNA test...

Hurricane Sally's Fierce Rain Shows How Climate Change Raises Storm Risks

As hurricanes go, Sally was not especially powerful. Rated a Category 2 storm when it struck the Gulf Coast on Wednesday, it was soon downgraded. But climate change likely made it more dangerous by slowing it down and feeding it more moisture, setting it up to pummel the region with wind and catastrophic rainfall.Sally was crawling at about 3 mph when its eye made landfall early Wednesday near...

Poop knives, arachnophobic entomologists win 2020 Ig Nobels

Maybe this year's Ig Nobels, the spoof prizes for dubious but humorous scientific achievement, should have been renamed the Ick Nobels. An anthropologist who tested an urban legend by fashioning a knife out of frozen human feces, and a man who found that spiders oddly give scientists who study insects the heebie-jeebies, are among the 2020 winners. Because of the coronavirus pandemic, Thursday's...

Lightning storm, easterly wind: How the wildfires got so bad

It began as a stunning light show on a mid-August weekend — lightning bolts crackling in the skies over Northern and Central California, touching down in grasslands and vineyards. The National Weather Service warned that the dry lightning striking a parched landscape “could lead to new wildfire.” Thousands of bolts ignited hundreds of fires in California and at least one in Oregon, setting...

EU details energy savings and renewables push to reach tougher climate target

The European Union needs to hike its renewable energy and energy saving targets, according to its analysis published on Thursday of how the bloc could make deeper emissions cuts this decade. The European Commission wants the EU to slash its greenhouse gas emissions by at least 55% by 2030, against 1990 levels, which experts say is the minimum needed to reach net zero emissions by 2050. The EU's...

Uganda reverses forest destruction by inviting in ... loggers

For decades, farmers hungry for land and families needing firewood whittled away at Uganda's forests, home to endangered gorillas, elephants and chimpanzees. Private companies are developing timber plantations as buffers next to protected forests. "Private planting is helping raise trees ... to absorb carbon and lock it there, but they are also stopping people from demanding timber in protected...

Western wildfire smoke causes East Coast haze, vivid sunsets

The smoke from dozens of wildfires in the western United States is stretching clear across the country — and even pushing into Mexico, Canada and Europe. The wildfires racing across tinder-dry landscape in California, Idaho, Oregon and Washington are extraordinary, but the long reach of their smoke isn't unprecedented. The sun was transformed into a perfect orange orb as it set over New York...

Slow-moving hurricanes that deluge coasts may be latest hazard of climate change

For Grant Saltz, who runs a barbecue restaurant in Mobile, Alabama, what struck him about Hurricane Sally was its steady, deliberate pace, after the storm rumbled into the U.S. Gulf Coast on Wednesday as a powerful Category 2 hurricane. "It’s so slow, this one," said Saltz, 38, while clearing away tree branches during a pause in the rains. Sally is not the most powerful storm to batter the...

NASA mulls possible mission to Venus after recent discovery of possible life

NASA is considering approving by next April up to two planetary science missions from four proposals under review, including one to Venus that scientists involved in the project said could help determine whether or not that planet harbors life. The U.S. space agency in February shortlisted four proposed missions that are now being reviewed by a NASA panel, two of which would involve robotic...

Mercury released by permafrost thaw puts Yukon River fish at risk - study

If carbon emissions continue at current rates, so much mercury will leach from thawing permafrost that fish in the Yukon River could become dangerous to eat within a few decades, according to a study published Wednesday in the journal Nature Communications. Current emissions rates threaten to trigger enough thaw release to drive mercury levels in Yukon River fish above federal safety guidelines...
