Exposing female rats to testosterone during pregnancy increases anxiety-like behavior in their offspring, possibly due to changes in the brain’s amygdala, a study finds.
View ArticleBuilding endurance through high-intensity exercise
High-intensity exercise may disrupt a muscle calcium channel and lead to increased expression of endurance genes, according to a study.
View ArticleWest Antarctic Ice Sheet collapse and sea level rise
A computer model suggests that the West Antarctic Ice Sheet (WAIS) may have begun an irreversible, centuries-long period of collapse that is predicted to raise sea levels by up to 3 meters.
View ArticleImproving recovery from brain injury
A therapeutic approach that reduces local inflammation and minimizes the risk of infection could improve outcomes after traumatic brain injury (TBI), a study in rodents suggests.
