This Longevity Study Across 5 Species Found a New Pathway to Reverse Aging

A new study in Nature hunted down another piece to the aging puzzle. In five species across the evolutionary scale—worms, flies, mice, rats, and humans—the team honed in on a critical molecular process that powers every single cell inside the body and degrades with age.

The process, called transcription, is the first step in turning our genetic material into proteins. Here, DNA letters are reworked into a “messenger” called RNA, which then shuttles the information to other parts of the cell to make proteins.

Scientists have long suspected that transcription may go awry with aging, but the new study offers proof that it doesn’t—with a twist. In all five of the species tested, as the organism grew older the process surprisingly sped up. But like trying to type faster when blindfolded, error rates also shot up.
