Chinese scientist who published first sequence of COVID virus protests after being evicted from lab
Shanghai, Apr 30: The first scientist to publish a sequence of the COVID-19 virus in China staged a sit-in protest outside his lab after authorities locked him out of the facility — a sign of the Beijing's continuing pressure on scientists conducting research on the coronavirus.
Zhang Yongzhen wrote in an online post Monday that he and his team had been suddenly notified they were being evicted from their lab, the latest in a series of setbacks, demotions and ousters since the virologist published the sequence in January 2020 without state approval.
When Zhang tried to go to the lab over the weekend, guards barred him from entering. In protest, he sat outside on flattened cardboard in drizzling rain, pictures from the scene posted online show. News of the protest spread widely on Chinese social media and Zhang told a colleague he slept outside the lab — but it was not clear Tuesday if he remained there.
"I won't leave, I won't quit, I am pursuing science and the truth!” he wrote in a post on Chinese social media platform Weibo that was later deleted.
In an online statement, the Shanghai Public Health Clinical Center said that Zhang's lab was being renovated and was closed for “safety reasons.” It added that it had provided Zhang's team an alternative laboratory space.
But Zhang wrote online that his team wasn't offered an alternative until after they were notified of their eviction, and that the lab offered didn't meet safety standards for conducting their research, leaving his team in limbo.
Zhang's latest difficulty reflects how China has sought to control information related to the virus: An Associated Press investigation found that the government froze meaningful domestic and international efforts to trace it from the first weeks of the outbreak. That pattern continues to this day, with labs closed, collaborations shattered, foreign scientists forced out and Chinese researchers barred from leaving the country.
When reached by phone on Tuesday, Zhang said it was “inconvenient” for him to speak, saying there were other people listening in. In an email Monday to collaborator Edward Holmes seen by AP, Zhang confirmed he was sleeping outside his lab after guards barred him from entering.
An AP reporter was blocked by a guard at an entrance to the compound housing Zhang's lab. A staff member at the National Health Commission, China's top health authority, said by phone that it was not the main department in charge and referred questions to the Shanghai government. The Shanghai government did not immediately respond to a request for comment.
Zhang's ordeal started when he and his team decoded the virus on Jan. 5, 2020, and wrote an internal notice warning Chinese authorities of its potential to spread — but did not make the sequence public. The next day, Zhang's lab was ordered temporarily shut by China's top health official, and Zhang came under pressure by Chinese authorities.
Around the time, China had reported several dozen people were being treated for a respiratory illness in the central city of Wuhan. Possible cases of the same illness had been reported in Hong Kong, South Korea and Taiwan involving recent travelers to the city.
Foreign scientists soon learned that Zhang and other Chinese scientists had deciphered the virus and called on China to release the sequence. Zhang published it on Jan. 11, 2020, despite a lack of government permission.
Sequencing a virus is key to the development of test kits, disease control measures and vaccinations. The virus eventually spread to every corner of the world, triggering a pandemic that disrupted lives and commerce, prompted widespread lockdowns and killed millions of people.
Zhang was later awarded prizes in recognition for his work.
But Zhang's publication of the sequence also prompted additional scrutiny of his lab, according to Holmes, Zhang's collaborator and a virologist at the University of Sydney. Zhang was removed from a post at the Chinese Center for Disease Control and Prevention and barred from collaborating with some of his former partners, crippling his research.
“Ever since he defied the authorities by releasing the genome sequence of the virus that causes COVID-19 there has been a campaign against him,” Holmes said. “He's been broken by this process and I'm amazed he has been able to work at all.”

Indigo cancels 67 flights from multiple airports due to bad weather, operational issues
Mumbai (PTI): Domestic carrier IndiGo on Thursday cancelled 67 flights from multiple airports due to "forecasted" bad weather and operational reasons, according to the airline's website.
Of the 67 cancelled flights, only four were for operational reasons, and the rest were due to "forecasted" bad weather at various airports, including Agartala, Chandigarh, Dehradun, Varanasi, Bengaluru, among others, as per the website.
Aviation regulator, DGCA, has announced the period between December 10 and February 10 next year as the official fog window this winter.

As part of the DGCA fog operations (CAT-IIIB) norms, airlines have to mandatorily roster pilots who are trained to operate in low-visibility conditions, as well as deploy a CAT-IIIB-compliant aircraft fleet for such operations.
Category-III is an advanced navigation system that empowers an aircraft to land under foggy conditions.
Category-III-A is a precision instrument approach and landing that enables a plane to land with a runway visual range (RVR) of 200 metres, while Category-III-B helps in landing with an RVR of under 50 metres.
IndiGo, whose operations are under DGCA monitoring after the cancellations of thousands of flights early this month, is already operating a curtailed schedule in compliance with the government's order.
Under its original winter flight schedule, the airline was permitted to operate 15,014 domestic flights per week, or about 2,144 flights per day, roughly six per cent higher than the 14,158 weekly flights it operated during the summer schedule of 2025.
However, after the massive disruptions, which saw the airline cancelling 1,600 flights on a single day on account of new rest norms for pilots, which allow more rest to the pilots, the government cut down the airline's domestic flight schedule by 10 per cent or 214 flights per day.
As a result of that, IndiGo can't operate more than 1,930 flights per day on domestic routes under its current winter schedule.
The Rahul Bhatia-controlled airline cancelled thousands of flights between December 1 and December 9 on account of a lack of proper planning, and crew shortage in implementing the new set of regulations for pilots' duty period and rest, which were put in place from November 1, thereby causing severe hardships to lakhs of air travellers.
Following this, the Directorate General of Civil Aviation (DGCA) formed a four-member panel, comprising Joint DG Sanjay Brahamane, Deputy Director General Amit Gupta, senior Flight Operations Inspector Kapil Manglik, and FOI Lokesh Rampal, with a mandate to identify the root causes of widespread operational disruptions at the Rahul Bhatia-controlled domestic carrier.
The panel, which has already grilled IndiGo CEO Pieter Elbers and Chief Operating Officer Isidre Porqueras as part of its probe, is expected to submit its report by this week.
Meanwhile, IndiGo, in a travel advisory on X, said, "Low visibility and fog over Bangalore has impacted flight schedule. We are keeping a close watch on the weather and doing our best where you need to be safely, smoothly".
Reacting to the advisory, an aggrieved passenger, in an X post, said, "My flight on December 20 from Bhubaneswar to Ahmedabad got delayed for more than five hours, and today my return flight from Ahmedabad to Bhubaneswar also got delayed more than three hours with the same excuse as bad weather. I am travelling with my senior citizen parents, and this delay is not acceptable. Need proper explanation, along with compensation".
