Harvard claims it found elixir of youth - but biologists have expressed concerns over the claims

The team discovered six chemical cocktails that reversed the aging process in human and mice skin cells 'by several years'. The team identified six chemical cocktails that restore aging cells to their younger state in less than a week. Jeffrey Flier is a Harvard University Distinguished Service Professor and Higginson Professor of Physiology and Medicine at Harvard Medical School. 'Now we show it's possible with chemical cocktails, a step towards affordable whole-body rejuvenation.' In 2020, Sinclair published a study detailing how he and his team have reset aging cells in mice to earlier versions of themselves.
