That pregnant feeling makes a fly start nesting

Across the animal kingdom, it’s not uncommon for pregnancy to change an expectant mom’s behavior. Even female flies have their own rudimentary way of “nesting,” which appears to be brought on by the stretch of their egg-filled abdomens rather than the act of mating, according to a Duke study published online October 16 in Cell Reports.

After mating, the female fruit fly Drosophila melanogaster dramatically shifts priorities as she prepares to lay eggs.

Rare genetic disease protects against bipolar disorder

Researchers uncover genetic pathway that could lead to better treatments

A team of scientists led by researchers at the UMass Medical School and the University of Miami Miller School of Medicine (UMMSM) have identified what is likely a key genetic pathway underlying bipolar disorder, a breakthrough that could lead to better drugs for treating bipolar affective disorder, as well as depression and other related mood disorders.

Myelin vital for learning new practical skills

New evidence of myelin's essential role in learning and retaining new practical skills, such as playing a musical instrument, has been uncovered by University College London (UCL) research. Myelin is a fatty substance that insulates the brain's wiring and is a major constituent of 'white matter'. It is produced by the brain and spinal cord into early adulthood as it is needed for many developmental processes, and although earlier studies of human white matter hinted at its involvement in skill learning, this is the first time it has been confirmed experimentally.
