The Biggest Ape That Ever Lived Was Not Too Big to Fail

Media Library

Standing nearly as tall as a basketball hoop and weighing as much as a grizzly bear, Gigantopithecus blacki was the greatest ape to ever live. For more than a million years during the Pleistocene, Gigantopithecus roamed southern China. But by the time ancient humans reached the region, Gigantopithecus had vanished. To determine why these prodigious primates died out, a team of scientists recently analyzed clues preserved in Gigantopithecus teeth and cave sediment. Their findings, published Wednesday in the journal Nature, reveal that these nearly 10-foot-tall apes were most likely doomed…

W.H.O. Dismisses Covid Origins Investigator for Sexual Misconduct

Media Library

The World Health Organization dismissed a lead investigator into the origins of the Covid-19 pandemic “following findings of sexual misconduct,” according to an agency spokeswoman. Peter K. Ben Embarek, an expert on food safety and animal-borne diseases, was dismissed last year; the dismissal was reported by The Financial Times on Wednesday. The findings stem from events that took place in 2015 and 2017, Marcia Poole, the W.H.O. spokeswoman, said in an email. The agency’s investigations team first learned about the allegations in 2018. At the time, “there was a significant…

Scientist Revisits Data on Raccoon Dogs and Covid, Stressing the Unknowns

Media Library

A new study of genetic data from a market in Wuhan, China, said the data did not support the case that the pandemic had started with illegally traded animals, touching off fresh debate about samples that other scientists see as critical pieces of the puzzle of how the coronavirus reached humans. The new study, which examined the relative amounts of animal and viral material in swabs taken from surfaces at the market in early 2020, said it was difficult to draw conclusions about whether given samples of the virus had…

Charles Lieber, Ex-Harvard Professor, Sentenced in China Ties Case

Chin@Strategy

Background Dr. Lieber, now 64, had been chairman of Harvard’s chemistry and chemical biology department. For his work on nanotechnology, he had been seen by some as a contender for the Nobel Prize. Since 2008, prosecutors said, his laboratory at Harvard had received research grants totaling $18 million from the Department of Defense and the National Institutes of Health. But he also secretly accepted money from China, which had established a government initiative, the Thousand Talents program, to gain access to scientific knowledge and expertise, often paying scientists lavishly. When…

A Fresh View of an Increasingly Familiar Black Hole

Chin@Strategy

A patch of pure nothing in a faraway galaxy has lately become the gravitational center of attention for radio astronomers. That would be a giant black hole, with the gravity of 6.5 billion suns, that spits high-energy particles from the center of the galaxy Messier 87, which lies some 50 million light-years from Earth. In 2019, astronomers operating a network of radio telescopes known as the Event Horizon Telescope dazzled the world by producing a radio map of the entity — the first-ever image of a black hole. It showed…

What Are Raccoon Dogs?

Chin@Strategy

On Thursday, scientists unveiled new data on the possible origins of the Covid-19 pandemic — and put a strange, squat creature squarely in the spotlight. Meet the raccoon dog; it earns its name from its black facial markings, which give the animal a masked appearance and a more-than-passing resemblance to those infamous raiders of urban trash cans. The animals were at least occasionally sold at the Huanan Seafood Wholesale Market, where many virologists suspect that the Covid-19 pandemic may have started. Scientists had previously announced that swabs from the market…

New Data Links Pandemic’s Origins to Raccoon Dogs at Wuhan Market

Chin@Strategy

An international team of virus experts said on Thursday that they had found genetic data from a market in Wuhan, China, linking the coronavirus with raccoon dogs for sale there, adding evidence to the case that the worst pandemic in a century could have been ignited by an infected animal that was being dealt through the illegal wildlife trade. The genetic data was drawn from swabs taken from in and around the Huanan Seafood Wholesale Market starting in January 2020, shortly after the Chinese authorities had shut down the market…

Health Experts Warily Eye XBB.1.5, the Latest Omicron Subvariant

Chin@Strategy

Three years into the pandemic, the coronavirus continues to impress virologists with its swift evolution. A young version, known as XBB.1.5, has quickly been spreading in the United States over the past few weeks. As of Friday, the Centers for Disease Control estimated that it made up 72 percent of new cases in the Northeast and 27.6 percent of cases across the country. The new subvariant, first sampled in the fall in New York State, has a potent array of mutations that appear to help it evade immune defenses and…

G.O.P. Senator’s Report on Covid Origins Suggests Lab Leak, but Offers Little New Evidence

Chin@Strategy

The top Republican on the Senate health committee said in a report on Thursday that the coronavirus pandemic was most likely caused by a laboratory incident in China. The report offered little new evidence, however, and was disputed by many scientists, including those whose research suggests that the outbreak originated instead at a live animal market. The report, released by Senator Richard M. Burr, Republican of North Carolina, grew out of a joint inquiry with the committee’s Democratic chairwoman that proponents of the effort hoped would add a measure of…

Fossilized Fish Reveal Earliest Known Prequel of ‘Jaws’

Chin@Strategy

Mention the ocean, and it’s hard not to think of jaws. The deep waters contain many tooth-lined mouths: the bear-trap maws of sharks and dolphins, the slack lips of shoaling and reef fish, the baleen-filter gape of enormous whales. Jawed fish eventually crawled out of the seas millions of years ago and gave rise to the jawboning vertebrates we are today. But when did such an evolutionary innovation arise? A pair of fossil beds discovered in Southern China suggest that the answer may lie tens of millions of years deeper…
