Shi Modified Bat Coronaviruses in Low Biosafety Wuhan Labs

(p. A1) Shi Zhengli, a top Chinese virologist, is once again at the center of clashing narratives about her research on coronaviruses at a state lab in Wuhan, the city where the pandemic first emerged.

The idea that the virus may have escaped from a lab had long been widely dismissed by scientists as implausible and shunned by others for its connection with former President Donald J. Trump. But fresh scrutiny from the Biden administration and calls for greater candor from prominent scientists have brought the theory back to the fore.

. . .

(p. A8) The Wuhan Institute of Virology employs nearly 300 people and is home to one of only two Chinese labs that have been given the highest security designation, Biosafety Level 4. Dr. Shi leads the institute’s work on emerging infectious diseases, and over the years, her group has collected over 10,000 bat samples from around China.

Under China’s centralized approach to scientific research, the institute answers to the Communist Party, which wants scientists to serve national goals. “Science has no borders, but scientists have a motherland,” Xi Jinping, the country’s leader, said in a speech to scientists last year.

Dr. Shi herself, though, does not belong to the Communist Party, according to official Chinese media reports, which is unusual for state employees of her status.

. . .

. . . some of her most notable findings have since drawn the heaviest scrutiny. In recent years, Dr. Shi began experimenting on bat coronaviruses by genetically modifying them to see how they behave.

In 2017, she and her colleagues at the Wuhan lab published a paper about an experiment in which they created new hybrid bat coronaviruses by mixing and matching parts of several existing ones — including at least one that was nearly transmissible to humans — in order to study their ability to infect and replicate in human cells.

Proponents of this type of research say it helps society prepare for future outbreaks. Critics say the risks of creating dangerous new pathogens may outweigh potential benefits.

The picture has been complicated by new questions about whether American government funding that went to Dr. Shi’s work supported controversial gain-of-function research. The Wuhan institute received around $600,000 in grant money from the United States government, through an American nonprofit called EcoHealth Alliance. The National Institutes of Health said it had not approved funding for the nonprofit to conduct gain-of-function research on coronaviruses that would have made them more infectious or lethal.

Dr. Shi, in an emailed response to questions, argued that her experiments differed from gain-of-function work because she did not set out to make a virus more dangerous, but to understand how it might jump across species.

“My lab has never conducted or cooperated in conducting GOF experiments that enhance the virulence of viruses,” she said.

. . .

Concerns have centered not only on what experiments Dr. Shi conducted, but also on the conditions under which she did them.

Some of Dr. Shi’s experiments on bat viruses were done in Biosafety Level 2 labs, where security is lower than in other labs at the institute. That has raised questions about whether a dangerous pathogen could have slipped out.

Ralph Baric, a prominent University of North Carolina expert in coronaviruses who signed the open letter in Science, said that although a natural origin of the virus was likely, he supported a review of what level of biosafety precautions were taken in studying bat coronaviruses at the Wuhan institute. Dr. Baric conducted N.I.H.-approved gain-of-function research at his lab at the University of North Carolina using information on viral genetic sequences provided by Dr. Shi.

Dr. Shi said that bat viruses in China could be studied in BSL-2 labs because there was no evidence that they directly infected humans, a view supported by some other scientists.

Labrador Noses May Be Cheaper and More Accurate Than Rapid Antigen Test at Detecting Covid-19

(p. A1) . . . three Labradors, operating out of a university clinic in Bangkok, are part of a global corps of dogs being trained to sniff out Covid-19 in people. Preliminary studies, conducted in multiple countries, suggest that their detection rate may surpass that of the rapid antigen testing often used in airports and other public places.

. . .

(p. A6) . . . as a group, the dogs being trained in Thailand — Angel, Bobby, Bravo and three others, Apollo, Tiger and Nasa — accurately detected the virus 96.2 percent of the time in controlled settings, according to university researchers. Studies in Germany and the United Arab Emirates had lower but still impressive results.

Sniffer dogs work faster and far more cheaply than polymerase chain reaction, or P.C.R., testing, their proponents say. An intake of air through their sensitive snouts is enough to identify within a second the volatile organic compound or cocktail of compounds that are produced when a person with Covid-19 sheds damaged cells, researchers say.

“P.C.R. tests are not immediate, and there are false negative results, while we know that dogs can detect Covid in its incubation phase,” said Dr. Anne-Lise Chaber, an interdisciplinary health expert at the School of Animal and Veterinary Sciences at the University of Adelaide in Australia who has been working for six months with 15 Covid-sniffing dogs.

Some methods of detection, like temperature screening, can’t identify infected people who have no symptoms. But dogs can, because the infected lungs and trachea produce a trademark scent. And dogs need fewer molecules to nose out Covid than are required for P.C.R. testing, Thai researchers said.

The Thai Labradors are part of a research project run jointly by Chulalongkorn University and Chevron. The oil company had previously used dogs to test its offshore employees for illegal drug use, and a Thai manager wondered whether the animals could do the same with the coronavirus.

. . .

Dogs, whose wet snouts have up to 300 million olfactory receptors compared with roughly six million for humans, can be trained to memorize about 10 smell patterns for a specific compound, Dr. Kaywalee said. Dogs can also smell through another organ nestled between their noses and mouths.

Some research has suggested that dogs of various breeds may be able to detect diabetes, Parkinson’s disease, malaria and certain cancers — that is, the volatile organic compounds or bodily fluids associated with them.

Labradors are among the smartest breeds, said Lertchai Chaumrattanakul, who leads Chevron’s part of the dog project. They are affable, too, making them the ideal doggy detector: engaged and eager.

Mr. Lertchai noted that Labradors are expensive, about $2,000 each in Thailand. But the cotton swabs and other basic equipment for canine testing work out to about 75 cents per sample. That is much cheaper than what’s needed for other types of rapid screening.

The Promise of Gene Editing Is Greater Than the Peril

(p. C1) The Berkeley biochemist [Jennifer Doudna] had helped to invent a powerful new technology that made it possible to edit the human genome—an achievement that made her the recipient of a Nobel Prize in 2020. The innovation was based on a trick that bacteria have used for more than a billion years to fight off viruses, a talent very relevant to us humans these days. In their DNA, bacteria develop clustered, repeated sequences (what scientists call CRISPRs) that can recognize and then chop up viruses that attack them. Dr. Doudna and others adapted the system to create a tool that can edit DNA—opening up the potential for curing genetic diseases, creating healthier babies, inventing new vaccines, and helping humans to fight their own wars against viruses.

. . .

(p. C2) . . . the advances in CRISPR technology, combined with the havoc wrought by the Covid-19 pandemic, have pushed me to be more open to gene editing. I now see the promise of CRISPR more clearly than the peril. If we are wise in how we use it, biotechnology can make us more able to fend off lethal viruses and overcome serious genetic defects.

After millions of centuries during which evolution happened “naturally,” humans now can hack the code of life and engineer our own genetic futures. Or, for those who decry gene editing as “playing God,” let’s put it this way: Nature and nature’s God, in their wisdom, have evolved a species that can modify its own genome.

Media Used “Censorship and Vilification” to Suppress Wuhan Lab-Leak Theory

(p. A23) If it turns out that the Covid pandemic was caused by a leak from a lab in Wuhan, China, it will rank among the greatest scientific scandals in history: dangerous research, possibly involving ethically dubious techniques that make viruses more dangerous, carried out in a poorly safeguarded facility, thuggishly covered up by a regime more interested in propaganda than human life, catastrophic for the entire world.

But this possible scandal, which is as yet unproved, obscures an actual scandal, which remains to be digested.

I mean the long refusal by too many media gatekeepers (social as well as mainstream) to take the lab-leak theory seriously. The reasons for this — rank partisanship and credulous reporting — and the methods by which it was enforced — censorship and vilification — are reminders that sometimes the most destructive enemies of science can be those who claim to speak in its name.

. . .

Was it smart for science reporters to accept the authority of a February 2020 letter, signed by 27 scientists and published in The Lancet, feverishly insisting on the “natural origin” of Covid? Not if those reporters had probed the ties between the letter’s lead author and the Wuhan lab (a fact, as the science writer Nicholas Wade points out in a landmark essay in The Bulletin of the Atomic Scientists, that has been public knowledge for months).

Was it wise to suppose that the World Health Organization, which has served as a mouthpiece for Chinese regime propaganda, should be an authority on what counted as Covid “misinformation” by Facebook, which in February [2021] banned the lab-leak theory from its platform? Not if the aim of companies like Facebook is to bring the world closer together, as opposed to laundering Chinese government disinformation while modeling its illiberal methods.

. . .

Yet the lab-leak theory, whether or not it turns out to be right, was always credible. Even if Tom Cotton believed it. Even if the scientific “consensus” disputed it. Even if bigots — who rarely need a pretext — drew bigoted conclusions from it.

Good journalism, like good science, should follow evidence, not narratives. It should pay as much heed to intelligent gadflies as it does to eminent authorities. And it should never treat honest disagreement as moral heresy.

Anyone wondering why so many people have become so hostile to the pronouncements of public-health officials and science journalists should draw the appropriate conclusion from this story. When lecturing the public about the dangers of misinformation, it’s best not to peddle it yourself.

Covid-19 Patents Provide Funding for Development of Future Vaccines

(p. A25) South Africa and India have petitioned the World Trade Organization to suspend some intellectual property protections from Covid-19 drugs, vaccines and diagnostic technologies. In support of the effort, Doctors Without Borders began a social media campaign urging governments to “put lives over profits,” warning of “pharma profiteering” and urging support for “#NoCovidMonopolies.”

. . .

Intellectual property rights, including patents, grant inventors a period of exclusivity to make and market their creations. By affording these rights to those who create intangible assets, such as musical compositions, software or drug formulas — people will invent more useful new things.

Development of a new medicine is risky and costly. Consider that scientists have spent decades — and billions of dollars — working on Alzheimer’s treatments, but still have little to show for it. The companies and investors who fund research shoulder so much risk because they have a shot at a reward. Once a patent expires, generic companies are free to produce the same product. Intellectual property rights underpin the system that gives us all new medicines, from psychiatric drugs to cancer treatments.

. . .

Eroding patent protections has far-reaching consequences.

Take “messenger RNA,” the technology platform that supports the vaccines from Pfizer-BioNTech and Moderna. Ozlem Tureci and Ugur Sahin, the wife-and-husband team at the helm of BioNTech, began exploring the use of mRNA more than 25 years ago and founded their company in 2008. Theoretically, mRNA can instruct the body to engineer proteins, including ones that increase immunity against infectious pathogens, cancers and rare genetic conditions. But the Covid-19 vaccines are the first truly successful applications of this technology. Scientists eager to explore future uses of mRNA will struggle to find investment if intellectual property protections are snatched away when others deem it necessary.

Older Americans Shifting to Entrepreneurship at Faster Pace

(p. B6) In April [2020], Dave Summers lost his job as director of digital media productions at the American Management Association, a casualty of layoffs brought on by the pandemic.

Mr. Summers, 60, swiftly launched his own business as a digital media producer, coach and animator who creates podcasts, webcasts and video blogs.

And in September, he and his wife, who teaches nursery school, moved from Danbury, Conn., to Maryville, Tenn., which they discovered while visiting their son in Nashville. “My new work is all virtual, so I can live anywhere,” he said. “Not only is it a cheaper place to live, we love hiking and the outdoors, and our new town is in the foothills of the Great Smoky Mountains.”

Droves of small businesses have been shuttered by the economic fallout of the coronavirus, but for Mr. Summers, starting a new one was the best option.

“I’m not sitting on a massive nest egg, so I need to work to keep afloat,” he said. “It’s also about being healthy and happy. I can’t just retire because underneath it all I’m creative, and I have to be busy doing stuff and helping people tell their stories.”

While the coronavirus pandemic is causing many older workers who have lost jobs, or who have been offered early retirement severance packages, to decide to leave the work force, others like Mr. Summers are shifting to entrepreneurship.

In fact, older Americans had already been starting new businesses at a fast rate. In 2019, research from the Kauffman Foundation, a nonpartisan group supporting entrepreneurship, found that more than 25 percent of new entrepreneurs were ages 55 to 64, up from about 15 percent in 1996.

Across the age spectrum, there has been a rise in new business start-ups since May [2020], according to the Census Bureau. The surge is likely “powered by newly unemployed individuals opting to start their own businesses, either by choice or out of necessity,” according to the Economic Innovation Group, a bipartisan public policy organization.

. . .

It turns out that the importance of entrepreneurship, or self-employment as a form of work, increases significantly with age, according to a report by Cal J. Halvorsen and Jacquelyn B. James of the Center on Aging & Work at Boston College.

According to the report: “While about one in six workers in their 50s are self-employed, nearly one in three are self-employed in their late 60s and more than 1 in 2 workers over the age of 80 are self-employed.

Li Wenliang Was Not an Outlier: Chinese Communists Punished at Least 587 for Speaking Out on Covid-19

(p. A6) At least seven people over the past week have been threatened, detained or arrested after casting doubt over the government’s account of the deaths of Chinese soldiers during a clash last year with Indian troops. Three of them are being detained for between seven and 15 days. The other four face criminal charges, including one man who lives outside China.

“The internet is not a lawless place,” said the police notices issued in their cases. “Blasphemies of heroes and martyrs will not be tolerated.”

Their punishment might have gone unnoticed if it weren’t for an online database of speech crimes in China. A simple Google spreadsheet open for all to see, it lists nearly 2,000 times when the government punished people for what they said online and offline.

The list — which links directly to publicly issued verdicts, police notices and official news reports over the past eight years — is far from complete. Most punishment takes place behind closed doors.

Still, the list paints a bleak picture of a government that punishes its citizens for the slightest hint of criticism. It shows how random and merciless China’s legal system can be when it punishes its citizens for what they say, even though freedom of speech is written into China’s Constitution.

. . .

(p. B3) Perhaps the most depressing items are those about people who were punished for what they said about the Covid-19 pandemic. On top of the list is Dr. Li Wenliang, who was reprimanded on Jan. 1, 2020, along with seven others for trying to warn the country about the coronavirus. He died of the virus in early February last year and is now remembered as the whistle-blower who tried to warn the world about the outbreak. But the spreadsheet lists 587 other cases.

Some Tech Startups, and Big Tech Firms, Want Workers Back in Office

(p. A1) For a tech guy, Mike de Vere, chief executive of fintech software startup Zest AI, has a contrarian return-to-work plan for his 100 employees: he wants them in the office full time.

Mr. de Vere said having employees together in the Burbank, Calif., headquarters improves communication, builds trust and allows for them to absorb knowledge from more experienced colleagues.

“We believe that we will be our best selves the more that we are together,” he said.

As more tech companies leverage the promise of flexible work arrangements as a competitive advantage, some are going the opposite route, betting that a strong office culture is what will help them recruit and retain the best talent.

Proponents of fully in-office work cite a range of benefits, from the collaboration that can result from happenstance interactions to easier communication. Plus, they add, plenty of people enjoy working in offices, especially after months spent, for some, in makeshift arrangements. Given the tech industry’s status as a bellwether for workplace trends, professionals in many industries are watching to see where it lands.

. . .

(p. A4) Dan Kaplan, a partner with organizational consulting firm KornFerry International, said the pandemic has permanently changed the equation for employees. The days of being in the office just to show your face are over: “People aren’t willing to do it anymore,” he said.

Though people early in their careers crave mentorship and the ability to build their social circles on the job, Mr. Kaplan said he’s started seeing flexibility as a point of negotiation between job seekers and employers. Candidates are trying to broker fewer days a week in the office and CEOs prefer more time in person, he said.

“There is going to be tension in the system,” he said. What tech companies do will have impacts across industries, he added.

. . .

An Amazon spokesman said the company plans to gradually return to an office-centric workweek because it “enables us to invent, collaborate, and learn together most effectively.”

Virologist “Dismayed” That Wuhan Lab Conducted Two Coronavirus Studies “With Only a Modest Level of Safety Measures”

(p. A6) On the heels of President Biden’s abrupt order to U.S. intelligence agencies to investigate the origins of the coronavirus, many scientists reacted positively, reflecting their push in recent weeks for more information about the work of a virus lab in Wuhan, China. But they cautioned against expecting an answer in the three-month time frame of the president’s request.

After long steering clear of the debate, some influential scientists have lately become more open to expressing uncertainties about the origins of the virus. If the two most vocal poles of the argument are natural spillover vs. laboratory leak, these new voices have added a third point of view: a resounding undecided.

“In the beginning, there was a lot of pressure against speaking up, because it was tied to conspiracies and Trump supporters,” said Akiko Iwasaki, an immunologist at Yale University. “There was very little rational discussion going on in the beginning.”

. . .

While researchers generally welcome a sustained search for answers, some warn that those answers may not arrive any time soon — if ever.

“At the end of this process, I would not be surprised if we did not know much more than we know now,” said W. Ian Lipkin, a virologist at the Mailman School of Public Health at Columbia University who was one of the first U.S. scientists to visit China in early 2020 and consult with public health authorities there.

China’s lack of cooperation with the W.H.O. has long fueled suspicions about how the coronavirus, known as SARS-CoV-2, had emerged seemingly from nowhere to seize the world.

. . .

Speaking recently to the former New York Times journalist Donald McNeil Jr., Dr. Lipkin said he was dismayed to learn of two coronavirus studies from the Wuhan Institute of Virology that had been carried out with only a modest level of safety measures, known as BSL-2.

In an interview with The Times, Dr. Lipkin said this fact wasn’t proof in itself that SARS-CoV-2 spread from the lab. “But it certainly does raise the possibility that must be considered,” he said.

A BSL-2 level of research would also add to the difficulty researchers will face trying to pin down clear evidence that a coronavirus infected the staff. At higher levels of security, staff regularly give blood samples that can be studied later for genetic material from viruses and antibodies against them. There may be no such record for SARS-CoV-2.

Biden’s “Abrupt Shift” on Wuhan Lab Origin of Covid-19

(p. A1) WASHINGTON — President Biden ordered U.S. intelligence agencies on Wednesday to investigate the origins of the coronavirus, indicating that his administration takes seriously the possibility that the deadly virus was accidentally leaked from a lab, in addition to the prevailing theory that it was transmitted by an animal to humans outside a lab.

. . .

But the president’s carefully worded directive underscored a new surge in interest about the lab, which President Donald J. Trump and some of his top aides repeatedly blamed for the pandemic. Some scientists attributed the renewed focus on the lab to Mr. Trump’s departure from the White House — and being less identified with the theory — while others said it reflected the deep frustrations with the recent W.H.O. report that was co-written by Chinese scientists.

. . .

(p. A8) “For over a year, anyone asking questions about the Wuhan Institute of Virology has been branded as a conspiracy theorist,” Mr. Hawley said. “The world needs to know if this pandemic was the product of negligence at the Wuhan lab, but the C.C.P. has done everything it can to block a credible investigation.”

In the past several days, the White House had played down the need for an investigation led by the United States and insisted that the W.H.O. was the proper place for an international inquiry. Mr. Biden’s statement on Wednesday was an abrupt shift.

. . .

Scientists had been reluctant to discuss the lab leak hypothesis last year because they had been on guard against disinformation, said Marc Lipsitch, a Harvard epidemiologist.

“Nobody wants to succumb to conspiracy theories,” he said.

But the March report by the group of W.H.O.-chosen experts in collaboration with Chinese scientists, dismissing the possibility of a lab leak as “extremely unlikely,” compelled some scientists to speak out.

“When I read that, I was very frustrated,” said Akiko Iwasaki, an immunologist at Yale University. Along with Professor Lipsitch, she signed a letter published in the journal Science this month saying that there was not enough evidence to decide whether a natural origin or an accidental laboratory leak caused the coronavirus pandemic.

“I think it’s really an unanswered question that really needs more rigorous investigation,” Dr. Iwasaki added.

From the earliest weeks of the outbreak, the Chinese government has worked to delay, deflect or block independent investigation of the virus’s origins.

Chinese officials said in early 2020 that the outbreak began at a Wuhan market, and they blamed illegal wildlife sales there. They did so despite having evidence that undermined that theory: Early data showed that four of the first five coronavirus patients had no clear links to the market. The government resisted accepting an international scientific mission.

Mainstream Elevates Wuhan Lab COVID-19 Origin That They “Once Dismissed as a Conspiracy Theory”

(p. A1) DANAOSHAN, China—On the outskirts of a village deep in the mountains of southwest China, a lone surveillance camera peers down toward a disused copper mine smothered in dense bamboo. As night approaches, bats swoop overhead.

This is the subterranean home of the closest known virus on Earth to the one that causes Covid-19. It is also now a touchpoint for escalating calls for a more thorough probe into whether the pandemic could have stemmed from a Chinese laboratory.

In April 2012, six miners here fell sick with a mysterious illness after entering the mine to clear bat guano. Three of them died.

Chinese scientists from the Wuhan Institute of Virology were called in to investigate and, after taking samples from bats in the mine, identified several new coronaviruses.

Now, unanswered questions about the miners’ illness, the viruses found at the site and the research done with them have elevated (p. A12) into the mainstream an idea once dismissed as a conspiracy theory: that SARS-CoV-2, the virus that causes Covid-19, might have leaked from a lab in Wuhan, the city where the first cases were found in December 2019.
