- Harvard University researcher Dr. David Sinclair is facing backlash from the longevity society.
- Critics say his claims about “reverse aging” go too far, the Wall Street Journal reported.
- Longevity medicine is attracting billions of dollars of investment from some of the world's wealthiest executives.
Harvard University researcher Dr. David Sinclair has found himself at the center of controversy within the longevity community.
Sinclair has long been a figurehead of the longevity movement. He has founded several biotech companies focused on reversing the effects of aging, earned critical acclaim for his research, and cultivated a loyal fan base who trust his lifestyle tips. I'm here.
He has also received similar criticism from critics who say his research is not always supported by sufficient evidence. But over the past few months, Sinclair has been battling a new level of backlash from his colleagues and researchers who say his claims to cure aging go too far, The Wall Street Journal reported.
Is it a question of semantics?
The controversy began on February 29, when Sinclair's dog supplement company Animal Biosciences issued a press release.
“After years of collaborative research and clinical trials, NCSU and Animal Biosciences have developed the first supplement proven to reverse aging in dogs,” Professor Sinclair said in a statement, according to Newsweek. I'm very proud of the team.”
Mr Sinclair claims he was misquoted. “The actual quote I approved was 'Proven to reverse the effects of aging in dogs,'” he told Barron's, adding, “I felt this was a reasonable statement.”
Scientists rushed to refute this claim. “The data is not good. You're saying it's false and you're selling it,” Dr. Nir Barzilai told the Journal. “Divestment goes too far.'' Dozens of scientists have resigned from the Academy for Healthy Span Research, a nonprofit association of longevity researchers that Mr. Sinclair co-founded and chairs.
Biologist Dr. Matt Kaeberlein, who was among the many to resign, described Sinclair at X as the definition of a “snake oil salesman.”
Sinclair resigned from the academy in March, the magazine reported, based on an email circulated by the academy. Barzilai then became president.
Dr. Sinclair did not respond to Business Insider's request for comment.
Animal Biosciences has once again issued a press release retracting the “reverse aging” claim. But scientists in the field say the problem is more fundamental: There is no way to reverse aging, much less measure it.
of biological age concept According to the National Institute on Aging, our true age – how our cells, tissues and organ systems look based on biochemistry – is gaining attention in the longevity world. However, it remains an ambiguous and controversial concept. There is no standard for normal aging.. Aging varies greatly from person to person.
Experts working to standardize longevity medicine say it could be years before it is recognized as a formal field like cardiology or neurology. According to MIT Technology Review. “This is a new field,” Andrea Meyer of the National University of Singapore and co-founder of the private “high-end” Chi Longevity clinic told MIT Technology Review. “We have to organize ourselves and set standards.”
Still, billions of dollars are being poured into research. longevity startup It attracted more than $5.2 billion in investments globally in 2022, according to PitchBook. And those supported by them The world's richest executives like Jeff Bezos and Peter Thiel They are dedicated to researching cellular aging and its treatments. It means that discussions about the semantics of aging become more relevant to our daily lives.
