At The Longevity Initiative, we’re welcoming the new year with five articles reviewing the old one. From billion-dollar bets on cellular reprogramming to mice living longer, Netflix documentaries and even a leaked hot-mic of Xi and Putin discussing living to 150, 2025 kept aging science in the headlines. The field saw progress, setbacks, and growing debates about policy, equity, and hype.
We’ll be releasing these over the course of this week, starting with 2025 in longevity science (the link in this post). Part 2 on the business of longevity came out today, and these will be followed by posts on funding, medicine, and comms, policy and politics on Friday.
2025 in longevity science: drugs make mice live 30% longer, human organ ageing clocks and more

Progress in longevity science could be the single biggest factor in how long and healthily people alive today will live.
Do you think enough progress was made in 2025? What areas would you like to see greater progress in? How can we speed up the research and its translation into medicine?
These are all questions The Longevity Initiative hopes to work on in 2026—and we’d be interested in your thoughts!
