Nostalgia warms the body as well as the soul
MinnPost: Nostalgia received a bad rap for centuries. It was long equated with homesickness, and thus associated with symptoms of grief and depression. In fact, the term nostalgia was coined by a Swiss physician, Johaness Hofer, in the 17th century to describe the constant yearning of soldiers for their homes and homeland when they were fighting in distant wars. Crying jags, a lack of appetite and an irregular heartbeat were considered the key symptoms of nostalgia during the 17th and 18th centuries.

Learn something new – your brain will thank you
CNN: The idea that learning a new skill - say juggling, cooking, or playing guitar - can be like an addiction is no joke. I should know. As a college professor/scientist, who has written about the dynamics of narcotics and self-control, I have spent the last 3 1/2 years all but addicted to learning to play guitar. Despite lacking anything that might remotely resemble musical talent, I find no day is complete without at least a little bit of time on the guitar.

A brain imaging study that came out last year proved what many scientists long suspected: Listening to music can lead the brain to release the neurotransmitter dopamine.

Most of the research on pregnancy brain has been done in rodents, which develop new smell-related brain cells during pregnancy. Humans aren't rats, of course, but at least one brain imaging study has found that new moms have more gray matter four months after birth.
