The protein TGF-beta controls the process by which cells in hair follicles—including stem cells—form new cells or die.This discovery could not only treat baldness, but also speed wound healing.

Researchers identify the gene C18ORF25 that promotes muscle strength when switched on by exercise, which could help develop treatments to mimic some of the benefits of working out.

Handgrip measures muscle strength and can significantly predict mortality in both young and older adults.

In a study of over 100,000 people over 30 years, the lowest risk of mortality was seen in adults who exercised over 150 minutes per week, with greater reductions from exercising over 500 minutes.
