How do muscles know what time it is?  

How do muscle cells prepare for the particular metabolic challenges of the day? Scientists have now investigated this question. The study has uncovered a metabolic network which is, contrary to expectations, not controlled by the brain but rather by the 'circadian clock' of muscle cells.

Scientists are reporting a novel way to use 'smart' nanocomposites to conserve a 16th-century British warship, the Mary Rose, and its artifacts. The new approach could help preserve other salvaged ships by eliminating harmful acids without damaging the wooden structures themselves.

How the brain suppresses the act of revenge  

Researchers have developed an economic game in which a participant is confronted with the fair behavior of one player and the unfair provocations of another player. They observed which areas were activated as the participant experienced unfairness and anger. Then scientists gave the participant the opportunity to take revenge. They thus identified the location in the brain of activations that are related to the suppression of the act of revenge in the dorsolateral prefontal cortex.

A team reports research that shines light on electrical breakdown for the smallest gap distances ever studied: five to 10 microns.
