In the perennial question of nature versus nurture, a new study suggests an intriguing connection between the two. Salk Institute scientists report in the journal Science that the type of mothering a female mouse provides her pups actually changes their DNA. The work lends support to studies about how childhood environments affect brain development in humans and could provide insights into neuropsychiatric disorders such as depression and schizophrenia.

Ancient genome analyses reveal mosaic pattern of goat domestication thousands of years ago
An international team of scientists, led by geneticists from Trinity College Dublin, have sequenced the genomes from ancient goat bones from areas in the Fertile Crescent where goats were first domesticated around 8,500 BC. They reveal a 10,000-year history of local farmer practices featuring genetic exchange both with the wild and among domesticated herds, and selection by early farmers.
