Health briefs: Heartbreaks really do hurt

Memories of devastating heartbreaks appear to trigger activity in the brain that's similar to when people suffer physical pain, new research suggests. "This tells us how serious rejection can be sometimes," said study author Edward E. Smith, director of cognitive neuroscience at Columbia University. "When people are saying 'I really feel in pain about this breakup,' you don't want to trivialize it and dismiss it by saying 'It's all in your mind.' "

The finding could lead to a better understanding of the link between emotional and physical pain, Smith said.

Putting a freeze on wrinkles

A new technology that temporarily zaps away forehead wrinkles by freezing the nerves shows promise in early clinical trials, researchers say. The technique, if eventually approved by the U.S. Food and Drug Administration, could provide an alternative to Botox and Dysport. Both are injectable forms of Botulinum toxin type A, a neurotoxin that, when injected in small quantities, temporarily paralyzes facial muscles, thereby reducing wrinkles.
