WASHINGTON D.C., United States (AFP) — People wearing plastic face shields or masks fitted with a valve can spray invisible droplets over a very wide area when they sneeze or cough, making the devices ineffective at preventing the spread of coronavirus when used on their own, a simulation model shows. In a report published Tuesday in the US journal Physics of Fluids, researchers at Florida Atlantic University used vertical and horizontal laser sheets to track […]
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) — The volume of lakes formed as glaciers worldwide melt due to climate change has jumped by 50 percent in 30 years, according to a new study based on satellite data. “We have known that not all meltwater is making it into the oceans immediately,” lead author Dan Shugar, a geomorphologist and associate professor at the University of Calgary, said in a statement. “But until now there […]
by Nina LARSON Agence France Presse GENEVA, Switzerland (AFP) — The World Health Organization urged governments Monday to engage with people demonstrating against Covid-19 restrictions and listen to their concerns, but stressed protesters needed to understand the virus was dangerous. Asked about recent demonstrations in a number of countries against coronavirus restrictions, WHO Director-General Tedros Adhanom Ghebreyesus said it was important to “listen to what people are asking, what people are saying”. “We should […]
by Marlowe HOOD PARIS, France (AFP) — The Greenland and Antarctic ice sheets, which hold enough frozen water to lift oceans 65 metres, are tracking the UN’s worst-case scenarios for sea level rise, researchers said Monday, highlighting flaws in current climate change models. Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change’s (IPCC) most extreme forecasts, which see the two ice sheets […]
by Marlowe HOOD Agence France Presse PARIS, France (AFP) — People who eat a lot of industrially processed junk food are more likely to exhibit a change in their chromosomes linked to ageing, according to research presented Tuesday at an online medical conference. Three or more servings of so-called “ultra-processed food” per day doubled the odds that strands of DNA and proteins called telomeres, found on the end of chromosomes, would be shorter compared […]
by Glenn CHAPMAN Agence France Presse Futurist entrepreneur Elon Musk late Friday demonstrated progress made by his Neuralink startup in meshing brains with computers, saying the work is essential to the future of humanity. Musk has long contended that a neural lace merging minds with machines is vital if people are going to avoid being so outpaced by artificial intelligence that, under the best of circumstances, humans would be akin to “house cats.” “It’s […]
PORT LOUIS, Mauritius (AFP) — Tens of thousands of Mauritians protested Saturday in the capital Saint-Louis over the government’s handling of a giant oil spill off its pristine Indian Ocean coast. The Japanese bulk carrier MV Wakashio crashed into a reef off southeastern Mauritius last month spewing more than 1,000 tonnes of oil into waters that are home to mangrove forests and endangered species. After the boat split in two, the larger piece was towed […]
MEXICO CITY, Mexico (AFP) — A robot at a hospital in the Mexican capital is providing a lifeline for coronavirus patients separated from their relatives and reducing the risk of infection for medical workers. “Hi, I’m LaLuchy Robotina! What’s your name?” the 1.4-meter-tall (4.6 feet) robot asks patients as it goes from room to room. It moves around on wheels and has a camera and display screen enabling relatives and doctors to chat with patients […]
WASHINGTON, United States (AFP) — The head of the US Food and Drug Administration raised the possibility in an interview published Sunday that a future vaccine against the coronavirus might be given emergency approval before the end of trials designed to ensure its safety and effectiveness. A request for such extraordinary approval would have to come from the vaccine developer, Stephen Hahn told the Financial Times. “If they do that before the end of […]
LOS ANGELES, United States (AFP) — Chadwick Boseman, star of the ground-breaking superhero movie “Black Panther,” has died after a private four-year battle with colon cancer, his publicist told AFP Friday. Boseman, 43, never publicly discussed his condition and continued to work on major Hollywood films during and between “countless” operations and chemotherapy, his family said in a statement. “It was the honor of his career to bring King T’Challa to life in ‘Black […]
by Issam AHMED Agence France-Presse WASHINGTON D.C., United States (AFP) — Water covers 70 percent of the Earth’s surface and is crucial to life as we know it, but how it got here has been a longstanding scientific debate. The puzzle was a step closer to being solved Thursday after a French team reported in the journal Science they had identified which space rocks were responsible, and suggested our planet has been wet ever since […]
by Nina LARSON GENEVA, Switzerland (AFP) — Global temperatures boosted by climate change will still be higher than usual despite the cooling effect of a La Nina weather phenomenon expected to develop in the coming months, the UN said Thursday. The World Meteorological Organization (WMO) said there was a 60 percent chance of a La Nina event between September and November. But WMO chief Petteri Taalas warned in a statement that “even if a La […]
