The Wallenberg Scholars programme supports and stimulates some of the most successful researchers at Swedish universities. Two researchers at Karolinska Institutet have now been awarded SEK 15 million each to be divided over a period of five years.

In a study in mice, Swedish and American scientists have identified a previously unknown protein that spurs muscle growth and increased power following resistance exercise – such as bodybuilding or weightlifting. The findings are presented in the journal Cell, and the scientists speculate that artificially raising the novel protein's levels might someday help prevent muscle mass loss caused by, for example, cancer, prolonged inactivity in hospital patients, and aging.
