UC Berkeley physicists create tiny bearings and springs out of carbon nanotubes for use in microscopic machines
UC Berkeley physicists have peeled the tips off carbon nanotubes to make seemingly frictionless bearings so small that some 10,000 would stretch across the diameter of a human hair.

Study links impulsive violence with brain's inability to regulate emotion
The human brain is wired with natural checks and balances that control negative emotions, but breakdowns in this regulatory system appear to dramatically heighten risk of impulsive violent behavior, according to findings of a University of Wisconsin-Madison study.

Animal model shows pain and tissue injury in newborns alters nerve circuitry and reaction to pain later in life
Working with an animal model, scientists at the National Institute of Dental and Craniofacial Research have provided the first physical evidence that pain and inflammation in newborns alters the development of pain pathway circuitry, causing a stronger response to pain in adulthood.
