UCSF researchers have discovered inherited DNA that increases risk for the most deadly brain cancers.
Scientists have long thought that processes occurring during sleep were responsible for cementing the salient experiences of the day into long-term memories. Now, however, a study of scampering rats suggests that the mechanisms at work during sleep are also active while the animals are awake -- and that they encode events more accurately.
A nationwide study of over 280,000 women showed that postmenopausal women who are overweight or obese have advanced breast cancer at significantly higher rates than women of normal weight or less than normal weight.
University of California, San Francisco researchers are reporting direct evidence that sleep in early life may play a crucial role in brain development.
Stanley B. Prusiner, MD, 55, today was named to receive the 1997 Nobel Prize in Physiology or Medicine for discovering and characterizing an entirely new class of proteins, called prions, which cause several rare and fatal neurodegenerative diseases.
