China’s “bat woman” has lashed out at US President Donald Trump, saying the he owes her country an apology as she again denied assertions that the novel coronavirus is linked to the lab where she works.
Wuhan Institute of Virology (WIV) Deputy Director Shi Zhengli (石正麗) said in an interview published in Science magazine that she and her colleagues encountered the virus in December last year, when reports of the disease first emerged in the city.
She said the lab had not seen or studied the virus before that.

“US President Trump’s claim that SARS-CoV-2 was leaked from our institute totally contradicts the facts,” Shi said in the article published on Friday. “It jeopardizes and affects our academic work and personal life. He owes us an apology.”
Trump, who has repeatedly referred to COVID-19 as the “China Virus,” and US Secretary of State Michael Pompeo have suggested a link between the Wuhan lab and the outbreak, although no evidence has ever been presented publicly.
While Shi, who is renowned for her work on coronaviruses in bats, has previously dismissed any link between the virus and the lab, her comments in the interview provided the most detailed rebuttal yet:
The WIV has identified hundreds of bat viruses, but never anything close to SARS-CoV-2, Shi said.
Questions have been raised about a possible link with RaTG13, a bat virus similar to SARS-CoV-2.
Shi said the lab did not culture that bat virus, making an accident unlikely.
Shi said differences in the sequences of the two viruses suggest they diverged from a common ancestor 20 to 70 years ago.
Shi’s partial genome sequencing in 2016 of a coronavirus she called 4991 led to suspicions it was SARS-CoV-2, but she said 4991 is actually RaTG13: 4991 was named for the bat, and was switched to RaTG13 after the entire virus was sequenced.
Years of surveillance in Hubei Province has not turned up bat coronaviruses close to SARS-CoV-2, leading her to believe the jump from animals to humans happened elsewhere, she said.
Through the noise of rushing papers and whirring belts at a print factory in Kyoto, two creators watch their photo essay come to life in broadsheet form — part of an effort to win new audiences in the age of artificial intelligence (AI). Despite the decline of the publishing industry, self-publication and handmade “zine” magazines are growing in popularity in Japan, reflecting the nation’s enduring love of paper in the digital era. While speaking to Agence France-Presse at the plant, his hands black with ink, one of the creators, Kazuma Obara, said: “I think [paper] is a medium that engages all five
‘CROSSING THE LINE’: China’s embassy in Seoul criticized US Forces Korea Commander General Xavier Brunson, asking if his ‘hostile’ remarks were authorized by Washington South Korea and the US are in talks over recent public remarks by the commander of US Forces Korea, Seoul’s presidential office said yesterday, after the comments drew sharp criticism from China. In a recent podcast interview, US Forces Korea Commander General Xavier Brunson described South Korea as “the dagger in the heart of Asia” from China’s east coast, prompting the Chinese embassy in Seoul to say that he had “truly crossed the line.” The interview came amid growing speculation that Washington might seek to expand the role of US Forces Korea in countering the growing regional influence of China, a key
Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the 1990s shooter game Doom and said they are just scratching the surface of what the neurons could be capable of doing. It is the science-fiction work of biotech boffins at Cortical Labs, who researched and developed the technology that harnesses the workings of the brain’s networking system. Each so-called “biological computer” contains about 200,000 living human brain cells, grown from stem cells that were harvested from blood donations. Having mastered the simple computer game Pong, where a paddle is moved up and down to send a ball
France experienced its hottest spring on record, the French weather service said on Tuesday, after an exceptional early heat wave that also broke highs for the season in England and Wales. Meteo-France said the average nationwide temperature over March to May was 13.8°C — about 1.7°C above the norm, and surpassing records set in 2011 and 2020. “The warmest spring since records began in 1900,” it said in a bulletin. All three months were warmer than average, but the onset of an “unprecedented heatwave” late last month pushed the mercury to highs typically seen at the height of the summer. “Our country had never
