An observational study of 2,402 people, with a median age of 66.1 years, linked hearing loss to weaker connections between brain regions.An observational study of 2,402 people, with a median age of 66.1 years, linked hearing loss to weaker connections between brain regions.
A one-point higher social connection score was linked to a 0.04-point higher standardised capacity score, but not clearly slower decline.A one-point higher social connection score was linked to a 0.04-point higher standardised capacity score, but not clearly slower decline.
Researchers examined 51 genes for signalling molecules and found that 16 supported efficient regeneration, stem cell function or both in asexual planarian flatworms.Researchers examined 51 genes for signalling molecules and found that 16 supported efficient regeneration, stem cell function or both in asexual planarian flatworms.

In adults with cardiometabolic multimorbidity, models estimated 4.83 independent years at ages 60–90 with low isolation and no loneliness, versus 0.65 with both.In adults with cardiometabolic multimorbidity, models estimated 4.83 independent years at ages 60–90 with low isolation and no loneliness, versus 0.65 with both.
