There are lots of biotech startups working on potentially working treatments (not like the billionaire founded ones sadly, where they mostly aim for some silver bullet treatment.), if you want a simplified recurring email information (it’s not the simplest but it gets information through IMO, I’m not a biologist for example) subscribe to fight agings newsletter; https://www.fightaging.org/newsletter/

Fightaging.org also has a lot of information.

Cheers!
