Female gorillas must balance the reproductive costs of staying with or leaving an older male

When a gorilla group's silverback is close to the end of his reproductive years, females face a dilemma: Should they stay with him until he dies or leave him for another male? A team of researchers from the Max Planck Institute of Evolutionary Anthropology has now found that both strategies bear its costs: females face reproductive costs of staying with an older male as well as costs when they transfer to a new silverback.

Suicide is preventable: How can we help our teens?

Every October, after school starts—and each May, as it ends—there is a spike in the number of teenagers who go to the Yale New Haven Children's Hospital (YNHCH) emergency department because they are thinking about attempting suicide.

For some, it's gender concerns—they have come out as trans or non-binary, and their peers are shutting them out.
