From The Guardian:
Short form: Harvard scientists managed to turn old (genetically engineered) mice into young mice by injecting them with enzmes that tinkered with their telomeres (sort of the “best if used by” dates on the end of DNA chains).
A few things:
- The mice used were modified specifically to have messed-up telomeres in the first place.
- This same trick in humans might cause cancer.
- If it does work in humans, will people demand it as part of their free health care?
- Will people still demand to retire by 65 and be taken care of for the rest of their lives by the few remaining younger workers?
Sure, sounds great… but there are some minor issues. Not least of them are the prospects of destroying civilization utterly in a massive economic collapse coupled with a generational war.
