learning to walk stairs

the son of one of my daughter's friends is learning to climb the stairs! Now I remember why I was so slim when my daughters were young!

Here is what I am reading today:

“Scientists have isolated a set of proteins that accounts for over 130 brain diseases, including diseases such as Alzheimer’s disease, Parkinson’s disease, epilepsies and forms of autism and learning disability. The team showed that the protein machinery has changed relatively little during evolution, suggesting that the behaviors governed by and the diseases associated with these proteins have not changed significantly over many millions of years. The findings open several new paths toward tackling these diseases.”

“It is well known that music arouses emotions. But why do some musical performances move us, while others leave us flat? Why do musicians spend years perfecting the subtle nuances that bring us to tears? Scientists at Florida Atlantic University have now identified key aspects of musical performance that cause emotion-related brain activity, and they have shown for the first time how these performance nuances work in the brain, in real-time.”

“Researchers have reported some of the first evidence that chimpanzee youngsters in the wild may tend to play differently depending on their sex, just as human children around the world do.”

“Researchers have shed new light on dopamine’s role in the brain’s reward system, which could provide insight into impulse control problems associated with addiction and a number of psychiatric disorders.”
