Scientists map maturation of the human brain
... adolescence can lead to enduring changes in brain structure in adulthood. This work is the first to demonstrate that exposure to a significant stress during adolescence can impact neuronal connections in the adult brain. The researchers found that adult rats exposed to a social stress during adolescence (ages...Students of mixed races report suffering more health problems

For example, Asians had higher grade-point averages than whites and were more likely to have a college-educated parent, but children with both Asian and...Bone cells help call the shots for the blood's stem cells within
