Harvard scientists have identified a drug combo that may reverse aging in just one week: ‘A step towards affordable whole-body rejuvenation'

well there's some research that I would class as anti-aging, like using yamanaka factors to reset the epigenome. There is a pretty convincing theory that epigenetic degradation is in large part to blame for aging, because cells no longer do their intended functions. Like if a liver cell partially turns on the genes nescessary in a skin, heart, nerve cell and some liver cell functions are turned off etc..

If you can reset them to do what they are supposed to do again, then it follows that your body is "younger".

Afaik the genetic damage isn't that important for aging as the epigenetic damage.
