Growth hormone may shorten life span, study finds

A recent study published in Endocrinology found that mice engineered without the receptor for growth hormone lived almost one year longer than normal mice, suggesting that the natural hormone may actually shorten lifespan. The researchers are now searching for genes regulated by growth hormone that might play a specific role in life span.

Study describes brain changes during learning

A new study by Brown University researchers provides evidence that learning uses LTP to produce changes in the connections between brain cells, necessary for acquiring and storing new information. The study also validates a theory proposing that synapses are constantly modifying and closely related to LTP.
