Column: The COVID lab-leak claim isn't just an attack on science, but a threat to public health
Here’s an indisputable fact about the theory that COVID originated in a laboratory: Most Americans believe it to be true.
That’s important for several reasons. One is that evidence to support the theory is nonexistent. Another is that the claim itself has fomented a surge of attacks on science and scientists that threatens to drive promising researchers out of the crucial field of pandemic epidemiology.
That concern was aired in a commentary by 41 biologists, immunologists, virologists and physicians published Aug. 1 in the Journal of Virology. The journal probably isn’t in the libraries of ordinary readers, but the article’s prose is commendably clear and its conclusions eye-opening.
We now see a long-term risk of having fewer experts engaged in work that may help thwart future pandemics, and of fewer scientists willing to communicate the findings of sophisticated, fast-moving research topics that are important for global health.
— 41 scientists warn of the rise in anti-science disinformation
“The lab leak narrative fuels mistrust in science and public health infrastructures,” the authors observe. “Scientists and public health professionals stand between us and pandemic pathogens; these individuals are essential for anticipating, discovering, and mitigating future pandemic threats. Yet, scientists and public health professionals have been harmed and their institutions have been damaged by the skewed public and political opinions stirred by continued promotion of the lab leak hypothesis in the absence of evidence.”
Before exploring further how the lab leak theory has been exploited to undermine public confidence in science and scientists, let’s examine what’s known and unknown about the origins of SARS-CoV-2, the virus that causes COVID.
The so-called zoonosis hypothesis, which is favored by the vast majority of the virological and epidemiological communities, is that the virus reached humans via a spillover from the animal kingdom, probably through the unregulated wildlife trade in Southeast Asia.
“Validating the zoonotic origin is a scientific question that relies on history, epidemiology, and genomic analysis, that when taken together, support a natural spillover as the probable origin,” the Virology paper states.
The lab leak theory holds that SARS-2 was created or manipulated into existence in the Wuhan Institute of Virology and escaped from the lab, whether deliberately or by accident.
Lab leak adherents bristle at the accusation that they’re conspiracy-mongers. Anthony Fauci, the retired director of the National Institute of Allergy and Infectious Diseases and the target of some of the most febrile attacks from the anti-science crowd, acknowledged at a June 3 House hearing that the lab leak theory was not inherently a conspiracy theory, conceptually—but that it had been exploited to support some truly crazy conspiracy narratives.
Fauci testified that he remained open to a lab leak narrative in principle, and that if any evidence for it emerged he would consider it seriously. That’s typical of most scientists, especially biologists, who are led by the infinite variability of the natural world to be innately averse to declaring anything conclusively possible or impossible.
The fact is, however, that one can’t advance the lab leak theory without positing a vast conspiracy encompassing scientists in China and the U.S., and Chinese and U.S. government officials. How else could all the evidence of a laboratory event that resulted in more than 7 million deaths worldwide be kept entirely suppressed for nearly five years? Some external hint of the event inevitably would have surfaced somewhere, somehow, by now. None has.
“Validating the lab leak hypothesis requires intelligence evidence that the WIV possessed or carried out work on a SARS-CoV-2 precursor virus prior to the pandemic,” the Virology paper asserts. “Neither the scientific community nor multiple western intelligence agencies have found such evidence.”
Despite that, “the lab leak hypothesis receives persistent attention in the media, often without acknowledgment of the more solid evidence supporting zoonotic emergence,” the paper says. The paper doesn’t name all the media culprits, but they include the independent investigative news site ProPublica and Vanity Fair.
It does take direct aim, however, at the New York Times, which on June 3 published a column by researcher Alina Chan asserting that the “pandemic probably started in a lab.” In a 2021 book, Chan had aired almost identical arguments that were largely refuted by experts in the field. Her more recent article “misrepresents and underplays the existing scientific data supporting a zoonotic origin of SARS-CoV-2,” the Virology paper reported.
I’ve written before about the smears, physical harassment and baseless accusations of fraud and other wrongdoing that lab leak propagandists have visited upon scientists whose work has challenged their claims; similar attacks have targeted experts who have worked to debunk other anti-science narratives, including those about global warming and vaccines.
Some of these attacks have come from elected officials seeking partisan cred, such as Sen. Rand Paul (R-Ky.) and Rep. Marjorie Taylor Greene (R-Ga.). They’ve been augmented by figures such as Donald Trump and Robert F. Kennedy Jr.
What’s notable about the Virology paper is that it represents a comprehensive and long-overdue pushback by the scientific community against such behavior. More to the point, it focuses on the consequences for public health and the scientific mission from the rise of anti-science propaganda.
Its authors are drawn from the faculties of the state universities of Arizona, California, Connecticut, Maryland, Florida and Ohio, as well as from Johns Hopkins, Duke and the Cleveland Clinic.
“Scientists have withdrawn from social media platforms, rejected opportunities to speak in public, and taken increased safety measures to protect themselves and their families,” the authors report.
“Some have even diverted their work to less controversial and less timely topics. We now see a long-term risk of having fewer experts engaged in work that may help thwart future pandemics, and of fewer scientists willing to communicate the findings of sophisticated, fast-moving research topics that are important for global health….Most worrisome for future preparedness, the next generation of scientists has well-founded fears about entering fields related to emerging viruses and pandemic science.”
The paper revisits the scene at the public interrogation by House Republicans on June 3. “The hearing,” it observes, “was often disrupted and marked by contentious, disrespectful, and unfounded calls for Dr. Fauci to be ‘prosecuted’ and imprisoned for ‘crimes against humanity.’”
By presupposing that evidence of a lab leak has been deliberately suppressed by leading scientists and scientific administrators, its promoters have cast “unsupported blame on scientists, many of whom had warned of the potential threat of, and need for effective countermeasures to prevent, zoonotic transfer of viruses into humans,” the authors write.
At a certain level, the popular embrace of scientific conspiracy theories is understandable. As the Swiss molecular biologist and science writer Philipp Markolin has observed, disinformation relies on myths that provide simple explanations for traumatic world events, like the pandemic, by positing that it was caused by shadowy, powerful actors. There’s never a shortage of grifters and manipulators using this public confusion to their advantage.
Thanks in part to social media, anti-science has become more virulent and widespread, the Virology authors write. Large numbers of researchers into SARS-2 have reported “harassment ranging from personal insults to threats of violence, ‘doxing,’ and personal contact,” according to the paper— of 1,281 scientists in several fields who responded to a survey by Science, 51% said they had experienced at least one form of harassment, sometimes over a period of years.
The Virology authors warn that the vilification of scientists whose research supports the zoonosis hypothesis will leave society defenseless when the next pandemic threat emerges.
“If these narratives are left unchecked, we become a society that dismisses and vilifies those with expertise and experience relevant to the challenges we face,” the authors write. “We then base decisions affecting large populations worldwide on speculation or chosen beliefs that have no grounding in evidence-based science.”
That’s what the future holds if we allow misinformation and disinformation, weaponized by sociopaths seeking financial or partisan gain, to guide our actions. We have been warned.
The sale of Warner Bros. — whether in pieces to Netflix or in its entirety to Paramount — is stirring mounting worries among Hollywood union leaders about the possible fallout for their members.
Unions representing writers, directors, actors and crew workers have voiced growing concerns that further consolidation in the media industry will reduce competition, potentially causing studios to pay less for content, and make it more difficult for people to find work.
“We’ve seen this movie before, and we know how it ends,” said Michele Mulroney, president of the Writers Guild of America West. “There are lots of promises made that one plus one is going to equal three. But it’s very hard to envision how two behemoths, for example, Warner Bros. and Netflix … can keep up the level of output they currently have.”
Last week, Netflix announced it agreed to buy Warner Bros. Discovery’s film and TV studio, Burbank lot, HBO and HBO Max for $27.75 a share, or $72 billion. It also agreed to take on more than $10 billion of Warner Bros.’ debt. But Paramount, whose previous offers were rebuffed by Warner Bros., has appealed directly to shareholders with an alternative bid to buy all of the company for about $78 billion.
Paramount said it will have more than $6 billion in cuts over three years, while also saying the combined companies will release at least 30 movies a year. Netflix said it expects its deal will have $2 billion to $3 billion in cost cuts.
Those cuts are expected to trigger thousands of layoffs across Hollywood, which has already been squeezed by the flight of production overseas and a contraction in the once booming TV business.
Mulroney said that employment for WGA writers in episodic television is down as much as 40% when comparing the 2023-2024 writing season to 2022-2023.
Executives from both companies have said their deals would benefit creative talent and consumers.
But Hollywood union leaders are skeptical.
“We can hear the generalizations all day long, but it doesn’t really mean anything unless it’s on paper, and we just don’t know if these companies are even prepared to make promises in writing,” said Lindsay Dougherty, Teamsters at-large vice president and principal officer for Local 399, which represents drivers, location managers and casting directors.
Dougherty said the Teamsters have been engaged with both Netflix and Paramount, seeking commitments to keep filming in Los Angeles.
“We have a lot of members that are struggling to find work, or haven’t really worked in the last year or so,” Dougherty said.
Mulroney said her union has concerns about both bids, either by Netflix or Paramount.
“We don’t think the merger is inevitable,” Mulroney said. “We think there’s an opportunity to push back here.”
If Netflix were to buy Warner Bros.’ TV and film businesses, Mulroney said that could further undermine the theatrical business.
“It’s hard to imagine them fully embracing theatrical exhibition,” Mulroney said. “The exhibition business has been struggling to get back on its feet ever since the pandemic, so a move like this could really be existential.”
But the Writers Guild also has issues with Paramount’s bid, Mulroney said, noting that it would put Paramount-owned CBS News and CNN under the same parent company.
“We have censorship concerns,” Mulroney said. “We saw issues around [Stephen] Colbert and [Jimmy] Kimmel. We’re concerned about what the news would look like under single ownership here.”
That question was made more salient this week after President Trump, who has for years harshly criticized CNN’s hosts and news coverage, said he believes CNN should be sold.
The worries come as some unions’ major studio contracts, including the DGA, WGA and performers guild SAG-AFTRA, are set to expire next year. Two years ago, writers and actors went on a prolonged strike to push for more AI protections and better wages and benefits.
The Directors Guild of America and performers union SAG-AFTRA have voiced similar objections to the pending media consolidation.
“A deal that is in the interest of SAG-AFTRA members and all other workers in the entertainment industry must result in more creation and more production, not less,” the union said.
SAG-AFTRA National Executive Director Duncan Crabtree-Ireland said the union has been in discussions with both Paramount and Netflix.
“It is as yet unclear what path forward is going to best protect the legacy that Warner Brothers presents, and that’s something that we’re very actively investigating right now,” he said.
It’s not clear, however, how much influence the unions will have in the outcome.
“They just don’t have a seat at the ultimate decision making table,” said David Smith, a professor of economics at the Pepperdine Graziadio Business School. “I expect their primary involvement could be through creating more awareness of potential challenges with a merger and potentially more regulatory scrutiny … I think that’s what they’re attempting to do.”
Businessman Brian Kahn has pleaded guilty to conspiracy to commit securities fraud in a case that brought down a hedge fund, helped lead to the bankruptcy of a retailer and damaged West Los Angeles investment bank B. Riley Financial.
Kahn, 52, admitted in a Trenton, N.J., federal court Wednesday to hiding trading losses that brought down Prophecy Asset Management in 2020. The Securities and Exchange Commission alleged the losses exceeded $400 million.
An investor lawsuit has accused Kahn of funneling some of the fund’s money to Franchise Group, a Delaware retail holding company assembled by the investor that owned Vitamin Shoppe, Pet Supplies Plus and other chains.
B. Riley provided $600 million through debt it raised to finance a $2.8-billion management buyout led by Kahn in 2023. It also took a 31% stake in the company and lent Kahn’s investment fund $201 million, largely secured with shares of Franchise Group.
Kahn had done deals with B. Riley co-founder Bryant Riley before partnering with the L.A. businessman on Franchise Group.
However, the buyout didn’t work out amid fallout from the hedge fund scandal and slowing sales at the retailers. Franchise Group filed for bankruptcy in November 2024. A slimmed-down version of the company emerged from Chapter 11 in June.
B. Riley has disclosed in regulatory filings that the firm and Riley have received SEC subpoenas regarding its dealings with Kahn, Franchise group and other matters.
Riley, 58, the firm’s chairman and co-chief executive, has denied knowledge of wrongdoing, and an outside law firm reached the same conclusion.
The failed deal led to huge losses at the financial services firm that pummeled B. Riley’s stock, which had approached $90 in 2021. Shares were trading Friday at $3.98.
The company has marked down its Franchise Group investment, and has spent the last year or so paring debt through refinancing, selling off parts of its business and other steps, including closing offices.
The company announced last month it is changing its name to BRC Group Holdings in January. It did not immediately respond to requests for comment.
At Wednesday’s plea hearing, Assistant U.S. Atty. Kelly Lyons said that Kahn conspired to “defraud dozens of investors who had invested approximately $360 million” through “lies, deception, misleading statements and material omissions.”
U.S. District Judge Michael Shipp released Kahn on a $100,000 bond and set an April 2 sentencing date. He faces up to five years in prison. Kahn, his lawyer and Lyons declined to comment after the hearing.
Kahn is the third Prophecy official charged over the hedge fund’s collapse. Two other executives, John Hughes and Jeffrey Spotts, have also been charged.
Hughes pleaded guilty and is cooperating with prosecutors. Spotts pleaded not guilty and faces trial next year. The two men and Kahn also have been sued by the SEC over the Prophecy collapse.

Chatty bots are sharing their hot takes through hundreds of thousands of AI-generated podcasts. And the invasion has just begun.
Though their banter can be a bit banal, the AI podcasters’ confidence and research are now arguably better than most people’s.
“We’ve just begun to cross the threshold of voice AI being pretty much indistinguishable from human,” said Alan Cowen, chief executive of Hume AI, a startup specializing in voice technology. “We’re seeing creators use it in all kinds of ways.”
AI can make podcasts sound better and cost less, industry insiders say, but the growing swarm of new competitors entering an already crowded market is disrupting the industry.
Some podcasters are pushing back, requesting restrictions. Others are already cloning their voices and handing over their podcasts to AI bots.
Popular podcast host Steven Bartlett has used an AI clone to launch a new kind of content aimed at the 13 million followers of his podcast “Diary of a CEO.” On YouTube, his clone narrates “100 CEOs With Steven Bartlett,” which adds AI-generated animation to Bartlett’s cloned voice to tell the life stories of entrepreneurs such as Steve Jobs and Richard Branson.
Erica Mandy, the Redondo Beach-based host of the daily news podcast called “The Newsworthy,” let an AI voice fill in for her earlier this year after she lost her voice from laryngitis and her backup host bailed out.
She fed her script into a text-to-speech model and selected a female AI voice from ElevenLabs to speak for her.
“I still recorded the show with my very hoarse voice, but then put the AI voice over that, telling the audience from the very beginning, I’m sick,” Mandy said.
Mandy had previously used ElevenLabs for its voice isolation feature, which uses AI to remove ambient noise from interviews.
Her chatbot host elicited mixed responses from listeners. Some asked if she was OK. One fan said she should never do it again. Most weren’t sure what to think.
“A lot of people were like, ‘That was weird,’” Mandy said.
In podcasting, many listeners feel strong bonds to hosts they listen to regularly. The slow encroachment of AI voices for one-off episodes, canned ad reads, sentence replacement in postproduction or translation into multiple languages has sparked anger as well as curiosity from both creators and consumers of the content.
Augmenting or replacing host reads with AI is perceived by many as a breach of trust and as trivializing the human connection listeners have with hosts, said Megan Lazovick, vice president of Edison Research, a podcast research company.
Jason Saldanha of PRX, a podcast network that represents human creators such as Ezra Klein, said the tsunami of AI podcasts won’t attract premium ad rates.
“Adding more podcasts in a tyranny of choice environment is not great,” he said. “I’m not interested in devaluing premium.”
Still, platforms such as YouTube and Spotify have introduced features for creators to clone their voice and translate their content into multiple languages to increase reach and revenue. A new generation of voice cloning companies, many with operations in California, offers better emotion, tone, pacing and overall voice quality.
Hume AI, which is based in New York but has a big research team in California, raised $50 million last year and has tens of thousands of creators using its software to generate audiobooks, podcasts, films, voice-overs for videos and dialogue generation in video games.
“We focus our platform on being able to edit content so that you can take in postproduction an existing podcast and regenerate a sentence in the same voice, with the same prosody or emotional intonation using instant cloning,” said company CEO Cowen.
Some are using the tech to carpet-bomb the market with content.
Los Angeles podcasting studio Inception Point AI has produced its 200,000 podcast episodes, accounting for 1% of all podcasts published on the internet, according to CEO Jeanine Wright.
The podcasts are so cheap to make that they can focus on tiny topics, like local weather, small sports teams, gardening and other niche subjects.
Instead of a studio searching for a specific “hit” podcast idea, it takes just $1 to produce an episode so that they can be profitable with just 25 people listening.
“That means most of the stuff that we make, we have really an unlimited amount of experimentation and creative freedom for what we want to do,” Wright said.
One of its popular synthetic hosts is Vivian Steele, an AI celebrity gossip columnist with a sassy voice and a sharp tongue. “I am indeed AI-powered — which means I’ve got receipts older than your grandmother’s jewelry box, and a memory sharper than a stiletto heel on marble. No forgetting, no forgiving, and definitely no filter,” the AI discloses itself at the start of the podcast.
“We’ve kind of molded her more towards what the audience wants,” said Katie Brown, chief content officer at Inception Point, who helps design the personalities of the AI podcasters.
Inception Point has built a roster of more than 100 AI personalities whose characteristics, voices and likenesses are crafted for podcast audiences. Its AI hosts include Clare Delish, a cooking guidance expert, and garden enthusiast Nigel Thistledown.
The technology also makes it easy to get podcasts up quickly. Inception has found some success with flash biographies posted promptly in connection to people in the news. It uses AI software to spot a trending personality and create two episodes, complete with promo art and a trailer.
When Charlie Kirk was shot, its AI immediately created two shows called “Charlie Kirk Death” and “Charlie Kirk Manhunt” as a part of the biography series.
“We were able to create all of that content, each with different angles, pulling from different news sources, and we were able to get that content up within an hour,” Wright said.
Speed is key when it comes to breaking news, so its AI podcasts reached the top of some charts.
“Our content was coming up, really dominating the list of what people were searching for,” she said.
Across Apple and Spotify, Inception Point podcasts have now garnered 400,000 subscribers.
