Workplace lifestyle intervention program improves health

A workplace lifestyle intervention program developed by the University of Pittsburgh significantly reduces risk factors for diabetes and heart disease. Participants lost an average of 5% of their body weight and increased physical activity, with 96% saying it was beneficial to offer the program.

Feeling sleepy? Might be the melatonin

Researchers found that zebrafish larvae with a mutation unable to produce melatonin slept half as long as normal fish. When the mutation was 'cured' by killing pineal gland cells, the fish returned to a normal sleep pattern. The study suggests naturally occurring melatonin plays an important role in regulating sleep.

Squeezing out new science from material interfaces

Scientists at the University of Illinois have determined the physical process dominating heat flow between metals and diamond, challenging previous theories. By applying extreme pressure to metal films on diamond, researchers found that phonons can 'feed' a higher frequency diamond phonon, regardless of metal stiffness.
