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…

Chinese Censorship Is Quietly Rewriting the Covid-19 Story

Chin@Strategy

Early in 2020, on the same day that a frightening new illness officially got the name Covid-19, a team of scientists from the United States and China released critical data showing how quickly the virus was spreading, and who was dying. The study was cited in health warnings around the world and appeared to be a model of international collaboration in a moment of crisis. Within days, though, the researchers quietly withdrew the paper, which was replaced online by a message telling scientists not to cite it. A few observers…

New data links Covid-19’s origins to raccoon dogs at Wuhan market

Chin@Strategy

Newly released genetic data gathered from a live food market in Wuhan has linked Covid-19 with raccoon dogs, adding weight to the theory that infected animals sold at the site started the coronavirus pandemic, researchers involved in the work say. Swabs collected from stalls at the Huanan seafood market in the two months after it was shut down on 1 January 2020 were previously found to contain both Covid and human DNA. When the findings were published last year, Chinese researchers stated that the samples contained no animal DNA. That…

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…

Hearing on Covid’s Origins Promises Politics Mixed With Substance

Chin@Strategy

WASHINGTON — House Republicans on Wednesday will dig into the origins of the coronavirus pandemic in a hearing that promises to be filled with political theater alongside substantive questions about laboratory safety and what, if anything, could have been done to prevent the worst public health crisis in a century. The hearing of the Select Subcommittee on the Coronavirus Pandemic is expected to focus largely on the intensifying debate over whether Covid-19 was the result of a laboratory leak. In advance of the session, Republicans issued a memorandum critical of…

Hubble Telescope Faces Threat From SpaceX and Other Companies’ Satellites

Chin@Strategy

The Hubble Space Telescope, known for recording awe-inspiring images of the cosmos while advancing the field of astronomy, is under threat. Private companies are launching thousands of satellites that are photobombing the telescope — producing long bright streaks and curves of light that can be impossible to remove. And the problem is only getting worse. A study, published Thursday in the journal Nature Astronomy, reveals an increase in the percentage of images recorded by the Hubble that are spoiled by passing satellites. And the data goes only through 2021. Thousands…

What is in the CHIPS Act, Aimed at Childcare Expansion and National Security

Chin@Strategy

The Biden administration unveiled new rules Tuesday for its “Chips for America” program to build up semiconductor research and manufacturing in the United States, beginning a new rush toward federal funding in the sector. The Commerce Department has $50 billion to hand out in the form of direct funding, federal loans and loan guarantees. It represents one of the largest federal investments in a single industry in decades and highlights deepening concern in Washington about America’s dependence on foreign chips. Given the huge cost of building highly advanced semiconductor facilities,…

Where Did Covid Originate? Here’s What We Know and Don’t Know

Chin@Strategy

WASHINGTON — The Energy Department’s conclusion, with “low confidence,” that an accidental laboratory leak in China most likely caused the coronavirus pandemic has renewed questions about what sparked the worst public health crisis in a century — and whether the virus at the heart of it was somehow connected to scientific research. Scientists and spy agencies have tried assiduously to answer that question, but conclusive evidence is hard to come by. The nation’s intelligence agencies are split, and none of them changed their conclusions after seeing the Energy Department’s findings, officials…

Six lifestyle choices to slow memory decline named in 10-year study

Chin@Strategy

A combination of healthy lifestyle choices such as eating well, regularly exercising, playing cards and socialising at least twice a week may help slow the rate of memory decline and reduce the risk of dementia, a decade-long study suggests. Memory is a fundamental function of daily life that continuously declines as people age, impairing quality of life and productivity, and increasing the risk of dementia. Evidence from previous research has been insufficient to evaluate the effect of healthy lifestyle on memory trajectory, but now a study suggests that combining multiple…
