The studies, which are published in Nature Aging, show that such mutations can reduce muscle strength and accelerate blood vessel ageing. The results can be of significance to the treatment of age-related diseases.Wed, 20 Aug 2025 09:00:00 GMThttps://via.tt.se/pressmeddelande/4012917/?publisherId=3236933&lang=svfalsehttps://via.tt.se/pressmeddelande/3986341/new-research-confirms-that-neurons-form-in-the-adult-brain?lang=svA study in the journal Science presents compelling new evidence that neurons in the brain’s memory centre, the hippocampus, continue to form well into late adulthood.
