Sea ice in the Arctic Ocean has reached its minimum extent following the summer melt season, and coverage is not as low as it has been in recent years, scientists said Wednesday. The National Snow and Ice Data Center, at the University of Colorado, said that the minimum had most likely been reached on Thursday […]
Ancient human footprints preserved in the ground across the White Sands National Park in New Mexico are astonishingly old, scientists reported on Thursday, dating back about 23,000 years to the Ice Age. The results, if they hold up to scrutiny, would rejuvenate the scientific debate about how humans first spread across the Americas, implying that […]
A scientific task force on Thursday called for jettisoning a common measure of kidney function that adjusts results by race, providing different assessments for Black patients than for others. The adjustment may make Black patients seem less ill than they really are, according to many experts. Instead, doctors should rely on a race-neutral method for […]
Many of the donated doses bound for use in Africa, for example, were meant to come from the Serum Institute of India. But five months ago, the Indian government blocked the company from exporting any vaccines, ordering that the supply instead be directed to trying to stanch a raging second Covid wave in that country. […]
NEW DELHI — The lanky figure lugging a green Orvis carry-on was instantly recognizable as he paused on the jetway after his overnight flight from the United States. “Mr. Kerry,” waved a fellow passenger. “Are you here to save the climate?” John Kerry, the former United States senator and secretary of state, is now a […]
The astronauts on the Inspiration4 mission finally gave people on Earth a good look through their cupola on Friday. That’s a fancy word for dome. The Crew Dragon capsule that the Inspiration4 crew is traveling in has one, and it’s a special cupola, 46 inches in diameter and 18 inches high. It includes a single […]
Antony Hewish, a pioneer of radio astronomy and a discoverer of a surprising class of stars known as pulsars, for which he was awarded a Nobel Prize, died on Monday. He was 97. His death was announced by the University of Cambridge in England, where he had taught for many years. The announcement did not […]
After a summer of blistering heat across much of the country, the hotter-than-normal conditions that have contributed to severe drought across the West are forecast to continue into the fall, scientists with the National Oceanic and Atmospheric Administration said Thursday. Five states had their warmest June through August in 127 years of record-keeping. Not coincidentally, […]
Ginkgo is encouraging new biotech start-ups to piggyback on its technology, much as tech start-ups use Amazon Web Services to supply their underlying computing and data storage. Motif Foodworks, founded in 2018, is one. It makes ingredients for plant-based alternatives to meat and dairy products, and it relies on Ginkgo to provide yeast strains that […]
SpaceX trained the Inspiration4 crew in largely the same way it has trained NASA crews. To prepare themselves for the rigors of spaceflight, the crew members were swung around a large centrifuge at the National Aerospace Training and Research Center in Pennsylvania, simulating the forces they will experience during launch and re-entry into the atmosphere […]
