NEW YORK – The World Health Organisation (WHO) rebuked Chinese officials on Friday for withholding research that may link Covid-19s origin to wild animals, asking why the data had not been made available three years ago and why it is now missing.
Before the Chinese data disappeared, an international team of virus experts downloaded and began analysing the research, which appeared online in January.
They say it supports the idea that the Covid-19 pandemic could have begun when illegally traded raccoon dogs infected humans at a Wuhan seafood market.
But the gene sequences were removed from a scientific database once the experts offered to collaborate on the analysis with their Chinese counterparts.
These data could have and should have been shared three years ago, WHO director-general Tedros Adhanom Ghebreyesus said.
The missing evidence now needs to be shared with the international community immediately, he said.
According to the experts who are reviewing it, the research offers evidence that raccoon dogs fox-like animals known to spread coronaviruses had left behind DNA in the same place in the Wuhan market that genetic signatures of the new coronavirus were also discovered.
To some experts, that finding suggests that the animals may have been infected and may have transmitted the virus to humans.
With huge amounts of genetic information drawn from swabs of animal cages, carts and other surfaces at the Wuhan market in early 2020, the genetic data had been the focus of restless anticipation among virus experts since they learnt of it a year ago in a paper by Chinese scientists.
A French biologist discovered the genetic sequences in the database last week, and she and a team of colleagues began mining them for clues about the origins of the Covid-19 pandemic.
That team has not yet released a paper outlining the findings.
But the researchers delivered an analysis of the material to a WHO advisory group studying Covid-19s origins this week in a meeting that also included a presentation by Chinese researchers regarding the same data.
The analysis seemed to clash with earlier contentions by Chinese scientists that samples taken in the market that were positive for the coronavirus had been ferried in by sick people alone, said Dr Sarah Cobey, an epidemiologist and evolutionary biologist at the University of Chicago who was not involved in recent research.
Its just very unlikely to be seeing this much animal DNA, especially raccoon dog DNA, mixed in with viral samples, if its simply mostly human contamination, Dr Cobey said.

All Covid-19 origin theories carry a major caveat right now Questions remain about how the samples were collected, what precisely they contained and why the evidence had disappeared.
In light of the ambiguities, many scientists reacted cautiously, saying that it was difficult to assess the research without seeing a complete report.
The idea that a lab accident could have accidentally set off the pandemic has become the focus of renewed interest in recent weeks, thanks in part to a fresh intelligence assessment from the US Department of Energy and hearings held by the new Republican House leadership.
But a number of virus experts not involved with the latest analysis said that what was known about the swabs gathered in the market buttressed the case that animals sold there had sparked the Covid-19 pandemic.
Its exactly what youd expect if the virus was emerging from an intermediate or multiple intermediate hosts in the market, Dr Cobey said. I think, ecologically, this is close to a closed case.
Dr Cobey was one of 18 scientists who signed an influential letter in the journal Science in May 2021 urging serious consideration of a scenario in which the virus could have spilled out of a laboratory in Wuhan.
On Friday, she said lab leaks continued to pose enormous risks and that more oversight of research into dangerous pathogens was needed.
But Dr Cobey added that an accumulation of evidence relating to the clustering of human cases around the Wuhan market, the genetic diversity of viruses there and now the raccoon dog data strengthened the case for a market origin.
The new genetic data does not appear to prove that a raccoon dog was infected with the coronavirus.
Even if it had been, the possibility would remain that another animal could have passed that virus to people, or even that someone infected with the virus could have transmitted it to a raccoon dog.
Some scientists stressed those points on Friday, saying that the new genetic data did not appreciably shift the discussion about the pandemics origins.
We know its a promiscuous virus that infects a bunch of species, said Dr David Fisman, an epidemiologist at the University of Toronto, who also signed the May 2021 letter in Science.

Dr Theodora Hatziioannou, a virologist at the Rockefeller University, said it was critical that the raw data be released.
But, she said, I think the evidence is overwhelming at the moment towards a market origin.
And the latest data, she said, makes it even more unlikely that this started somewhere else.
Dr Felicia Goodrum, an immunobiologist at the University of Arizona, said that finding the virus in an actual animal would be the strongest evidence of a market origin.
But finding virus and animal material in the same swab was close.
To me, she said, this is the next best thing. NYTIMES
The chief rabbi has described the BBC’s response to anti-IDF chanting at Glastonbury as “belated and mishandled” – as the punk-rap duo involved, Bob Vylan, said the UK government needed to talk about its “criminal inaction”.
Sir Ephraim Mirvis said “vile Jew-hatred” had been aired at the Somerset music festival and it was a “time of national shame”.
Confidence in the BBC’s “ability to treat antisemitism seriously” has been brought to a “new low”, he said in a post on X, adding that “outright incitement to violence and hatred” appeared to be acceptable if it was couched as “edgy political commentary”.
Ordinary people had not only failed to see incitement “for what it is” but had cheered it, chanted it, and celebrated it, he said. “Toxic Jew-hatred is a threat to our entire society,” he added.
Bob Vylan, posting a new statement on Instagram on Tuesday, said they were “not for the death of Jews, Arabs or any other race or group of people”.
Rather, they were for the “dismantling of a violent military machine” – the Israel Defence Forces.
Bob Vylan chanted “death to the IDF” at Glastonbury. As many as 95% of the IDF are thought to be Jewish.
In their statement, the group said they were a “distraction from the story” and that whatever “sanctions” they received would also be a distraction.
Their US visas have been revoked and United Talent Agency, their US representatives, have dropped them.

Referring to the war in Gaza, they claimed the UK government does not want them to ask “why they remain silent in the face of this atrocity”, “why they aren’t doing more to stop the killing” and “feed the starving”.
They added: “The more time they talk about Bob Vylan, the less time they spend answering for their criminal inaction.
“We are being targeted for speaking up. We are not the first, we will not be the last, and if you care for the sanctity of human life and freedom of speech, we urge you to speak up, too.”
It has emerged that Tim Davie, the BBC’s director-general, was at Glastonbury when the duo led chants of “Death to the IDF” which were broadcast live.
The prime minister’s spokesman, asked if the PM had confidence in Mr Davie, said Sir Keir Starmer had “confidence in the BBC”, adding: “The position of the director-general is a matter for the BBC’s board.”
Speaking in the Commons, Culture Secretary Lisa Nandy said “accountability” was important and it was something she had “impressed upon the BBC leadership”.
She added: “When you have one editorial failure, it’s something that must be gripped. When you have several, it becomes a problem of leadership.”
The cabinet minister said she’d called Mr Davie after Bob Vylan’s set had been broadcast to find out why it had aired, and why the feed had not been cut.
“I expect answers to these questions without delay,” she said.
Meanwhile Dame Caroline Dinenage, chair of the culture, media and sport committee, has written to Mr Davie in relation to the corporation’s Glastonbury coverage.
The committee has said the letter asks about editorial and decision-making processes and whether consideration was given to broadcasting with a delay. It also asks about staffing levels at the festival and contingency planning.

Avon and Somerset Police has begun a criminal investigation and is reviewing footage of both Bob Vylan and Kneecap’s performances at Glastonbury.
The force said a senior detective had been appointed – and it had been contacted by people from around the world.
“We… recognise the strength of public feeling,” it said.
During Kneecap’s set, one member suggested starting a “riot” outside his bandmate’s forthcoming court appearance, before clarifying that he meant “support”. Liam Og O hAnnaidh, also known as Mo Chara, is charged with a terror offence.

Bob Vylan had been due to tour the US before their visas were revoked.
US deputy secretary of state Christopher Landau said action had been taken “in light of their hateful tirade at Glastonbury, including leading the crowd in death chants”.
“Foreigners who glorify violence and hatred are not welcome visitors to our country,” he added.

During Bob Vylan’s set, the duo performed in front of a screen that showed several messages, including one that claimed Israel’s actions in Gaza amounted to “genocide”.
The war in Gaza began after Hamas militants attacked Israel on 7 October 2023 and killed 1,200 people and took about 250 hostage.
Israel’s offensive in Gaza has led to the deaths of more than 56,500 people, according to the Hamas-run health ministry, which does not differentiate between civilians and combatants.
Media watchdog Ofcom has said the BBC “clearly has questions to answer” over the live stream from Glastonbury.
A BBC spokesperson said: “The director-general was informed of the incident after the performance and at that point he was clear it should not feature in any other Glastonbury coverage.”
The broadcaster respects freedom of expression but “stands firmly against incitement to violence”, they said.
They added: “The antisemitic sentiments expressed by Bob Vylan were utterly unacceptable and have no place on our airwaves…
“The team were dealing with a live situation, but with hindsight we should have pulled the stream during the performance. We regret this did not happen.”

The Google Doodle is Alphabet’s most valuable piece of real estate, and on Tuesday, the company used that space to promote “AI Mode,” its latest AI search product.
Google’s Chrome browser landing pages and Google’s home page featured an animated image that, when clicked, leads users to AI Mode, the company’s latest search product. The doodle image also includes a share button.
The promotion of AI Mode on the Google Doodle comes as the tech company makes efforts to expose more users to its latest AI features amid pressure from artificial intelligence startups. That includes OpenAI which makes ChatGPT, Anthropic which makes Claude and Perplexity AI, which bills itself as an “AI-powered answer engine.”
Google’s “Doodle” Tuesday directed users to its search chatbot-like experience “AI Mode”
AI Mode is Google’s chatbot-like experience for complex user questions. The company began displaying AI Mode alongside its search results page in March.
“Search whatever’s on your mind and get AI-powered responses,” the product description reads when clicked from the home page.
AI Mode is powered by Google’s flagship AI model Gemini, and the tool has rolled out to more U.S. users since its launch. Users can ask AI Mode questions using text, voice or images. Google says AI Mode makes it easier to find answers to complex questions that might have previously required multiple searches.
In May, Google tested the AI Mode feature directly beneath the Google search bar, replacing the “I’m Feeling Lucky” widget — a place where Google rarely makes changes.
Tesla has unveiled its lithium-iron-phosphate (LFP) battery cell factory in Nevada and claims that it is nearly ready to start production.
Like several other automakers using LFP cells, Tesla relies heavily on Chinese manufacturers for its battery cell supply.
Tesla’s cheapest electric vehicles all utilize LFP cells, and its entire range of energy storage products, Megapacks and Powerwalls, also employ the more affordable LFP cell chemistry from Chinese manufacturers.
This reliance on Chinese manufacturers is less than ideal and particularly complicated for US automakers and battery pack manufacturers like Tesla, amid an ongoing trade war between the US and virtually the entire world, including China.

As of last year, a 25% tariff already applied to battery cells from China, but this increased to more than 80% under Trump before he paused some tariffs on China. It remains unclear where they will end up by the time negotiations are complete and the trade war is resolved, but many expect it to be higher.
The automaker had secured older manufacturing equipment from one of its battery cell suppliers, CATL, and planned to deploy it in the US for small-scale production.
Tesla has now released new images of the factory in Nevada and claimed that it is “nearing completion”:
Here are a few images from inside the factory (via Tesla):
Previous reporting stated that Tesla aims to produce about 10 GWh of LFP battery cells per year at the new factory.
The cells are expected to be used in Tesla’s Megapack, produced in the US. Tesla currently has a capacity to produce 40 GWh of Megapacks annually at its factory in California. The company is also working on a new Megapack factory in Texas.
It’s nice to see this in the US. LFP was a US/Canada invention, with Arumugam Manthiram and John B. Goodenough doing much of the early work, and researchers in Quebec making several contributions to help with commercialization.
But China saw the potential early and invested heavily in volume manufacturing of LFP cells and it now dominates the market.
Tesla is now producing most of its vehicles with LFP cells and all its stationary energy storage products.
It makes sense to invest in your own production. However, Tesla is unlikely to catch up to BYD and CATL, which dominate LFP cell production.
The move will help Tesla avoid tariffs on a small percentage of its Megapacks produced in the US. Ford’s effort is more ambitious.
It’s worth noting that both Ford’s and Tesla’s LFP plants were planned before Trump’s tariffs, which have had limited success in bringing manufacturing back to the US.
