Researchers have shown stress on preadolesecent and adult male mice induced an epigenetic mark in their sperm which reprogrammed their offspring's HPA axis, a region the the brain which governs stress response.

A new study reports symptoms of psychiatric disorders, such as anxiety and heightened response to stress, may be transmitted from mom to child, and even grandchildren by multiple non genetic mechanisms.

Additionally, children exposed to other early life adversities, such as poverty and food insecurity, show delayed signs of pubertal development.
Variations in brain and song structure in zebra finches is strongly influenced by environment, a new study suggests.
