Cellular ageing: turning back the clock restores vision in mice
A trio of genes may be key to making cells young again, and ultra precise measurement of a fundamental physics constant.
In this episode:
00:47 Reversing ageing
Researchers claim to have identified a method to revert cells in mice eyes back to a younger state.

29:38 Fine measurement of the fine-structure constant
The fine structure constant is a fundamental number that gives researchers an understanding of the laws of the universe. For years, scientists have been trying to get better measurements of it. This week, we see the most precise measurement yet.
Research Article: Morel et al.
News and Views: Fine-structure constant tests standard model
35:00 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, a holistic plan to tackle climate challenges, and the rarest pollinator of them all - a lizard.
