The debate about when dinosaurs developed feathers has taken a new turn with a paper refuting earlier claims that feathers were also found on dinosaurs’ relatives, the flying reptiles called pterosaurs. Pterosaur expert Dr David Unwin from the University of Leicester’s Centre for Palaeobiology Research, and Professor Dave Martill, ofContinue Reading
Discovery may indicate modern humans and Neanderthals lived in the area concurrently Modern humans arrived in the westernmost part of Europe 41,000 — 38,000 years ago, about 5,000 years earlier than previously known, according to Jonathan Haws, Ph.D., professor and chair of the Department of Anthropology at the University ofContinue Reading
The scientists who re-engineered the plastic-eating enzyme PETase have now created an enzyme ‘cocktail’ which can digest plastic up to six times faster. A second enzyme, found in the same rubbish dwelling bacterium that lives on a diet of plastic bottles, has been combined with PETase to speed up theContinue Reading
“It was a brilliant red in the low morning light.” A mysterious, many-armed sea creature — initially described as a large “red glob” — lying on a rocky shore in Washington has drawn in cephalopod experts across the country, each wondering what this gelatinous animal is. The 3.5-foot-long (1 meter)Continue Reading
Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds. Wormholes are tunnels in space-time that can theoretically allow travel anywhere in space and time, or even into another universe. Einstein’s theory of general relativity suggests wormholesContinue Reading
It sank after being attacked by Japanese aircraft. Divers in Southeast Asia have located the lost wreck of what’s thought to be a U.S. Navy submarine that sank in 1943 after it was attacked by Japanese aircraft. The submarine wreck — almost certainly that of USS Grenadier — was foundContinue Reading

Radiation exposure from two months on the moon is equivalent to roughly five months on the ISS A two-month stint on the moon would expose astronauts to roughly the same amount of radiation as they would get living on the International Space Station for five months, according to new measurementsContinue Reading
People infected by the novel coronavirus can have symptoms that range from mild to deadly. Now, two new analyses suggest that some life-threatening cases can be traced to weak spots in patients’ immune systems. At least 3.5 percent of study patients with severe COVID-19, the disease caused by the novelContinue Reading
Some mutations have no effect, while others could impact transmissibility. In early January, the first genome sequence of Sars-CoV-2 — the virus that causes COVID-19 — was released under the moniker “Wuhan-1”. This string of 30,000 letters (the A, T, C and Gs of the genetic code) marked day oneContinue Reading
