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

Analysis of gene sequences by international team finds Covid-positive samples rich in raccoon dog DNA

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.

Imperial College to shut joint research ventures with Chinese defence firms

Exclusive: two Chinese-sponsored aerospace research centres firms to close after warnings of ‘sleepwalking’ into aiding Chinese military

Imperial College will shut down two major research centres sponsored by Chinese aerospace and defence companies amid a crackdown on academic collaborations with China, the Guardian has learned.

The Avic Centre for Structural Design and Manufacturing is a long-running partnership with China’s leading civilian and military aviation supplier, which has provided more than £6m to research cutting-edge aerospace materials. The second centre is run jointly with Biam, a subsidiary of another state-owned aerospace and defence company, which has contributed £4.5m for projects on high-performance batteries, jet engine components and impact-resistant aircraft windshields. The centres’ stated goals are to advance civilian aerospace technologies, but critics have repeatedly warned that the research could also advance China’s military ambitions.

New clues shed light on ‘pivotal’ moment in the great Pacific migration

Archaeologists say find of tools and bones changes our understanding of the Lapita people, the first to make landfall in Remote Oceania

The peopling of the Pacific is one of the most significant migrations in human history. And now an archaeological discovery on a small island in Papua New Guinea has recast the early scope of this settlement, in a finding archaeologists say could explain the migration east three millennia ago.

The unearthing of animal bones and tools on Brooker Island, 200km east of mainland Papua New Guinea, suggests that the migration of Lapita people throughout Papua New Guinea was far more extensive than previously thought.

China shows way to ease lockdowns before vaccine, says report

UK experts say easing physical distancing would depend on rigorous testing and isolation

China’s tough lockdown and physical distancing measures in Wuhan and other provinces appear to have successfully ended new locally-transmitted coronavirus infections and may chart a route back to normal life, according to a report from Imperial College London.

The report, from Prof Neil Ferguson and his team, who have been the main modellers of the epidemic for the UK and other governments, suggests that it is possible to lift the physical distancing restrictions, as China has begun to do, without a resurgence of the epidemic.
