VIDEO: Learn how the baby brain changes from gestation to toddlerhood, and what parents, teachers and policymakers can do to ensure kids are set up for success

Treating the growing trauma of family separation

War, disasters, trafficking and immigration are tearing millions of children from their parents all around the world. A psychologist explores how to help them recover.

Short-circuiting the suicide cascade

Psychologists are seeking better ways to cut the link between dire thoughts and fatal action. Among their strategies: individualized plans for pulling back from the brink, and limiting access to deadly means, especially guns.

Sex strategies of the evolutionary kind

For women, a short-term fling may involve a quest for good genes or just a good time. It’s a puzzle for the researchers looking at how people choose mates.
