Tiny marine animals found to share 'diver's weight belt' technique with whales

Posted: 13 Jun 2011 06:35 AM PDT

A deep-sea mystery has been solved with the discovery that copepods -- tiny 3-millimeter-long marine animals eaten by herring, cod and mackerel -- use the same buoyancy control as whales.

Cooling the brain during sleep may be a natural and effective treatment for insomnia

Posted: 13 Jun 2011 06:35 AM PDT

Participants received all-night frontal cerebral thermal transfer by wearing a soft plastic cap on their head. The cap contained tubes that were filled with circulating water. The time that it took 12 subjects with primary insomnia to fall asleep (13 minutes) and the percentage of time in bed that they slept (89 percent) during treatment at the maximal cooling intensity were similar to 12 healthy controls (16 minutes and 89 percent).

Sleep type predicts day and night batting averages of Major League Baseball players

A Major League Baseball player's natural sleep preference might affect his batting average in day and night games, according to a new research. Players who are 'morning types' have a higher batting average in early games, but 'evening types' have the advantage in late games.

Birdsong independent of brain size: Sex difference in the brain varies according to social status

Posted: 12 Jun 2011 10:41 PM PDT

The brains of all vertebrates display gender-related differences. In songbirds, for example, the size of the brain areas that control their singing behaviour could be linked to the size of their song repertoires. In many songbird species, only the males sing and indeed, they do have larger song control areas in the brain than females. However, even species where both sexes sing identically, display the same sex differences in their brain structure. Researchers in Germany have now demonstrated for the first time in the white-browed sparrow weaver, an African songbird, that the extent of these sex differences in the brain varies according to social status, and cannot be explained by singing behaviour as previously thought.

Single GFP-expressing cell is basis of living laser device

Researchers have developed a device in which a single cell genetically engineered to express green fluorescent protein is used to amplify the light particles called photons into nanosecond-long pulses of laser light.
