A typical female selects a mate from a chorus of males and then - silently - signals her beau. But the female concave-eared torrent frog, Odorrana tormota, has a more direct method of declaring her interest: She emits a high-pitched chirp that to the human ear sounds like that of a bird... http://www.sciencecentric.com/news/08051106.htm http://www.sciencecentric.com/news/08051106.htm Sun, 11 May 2008 18:22:00 GMT At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs... http://www.sciencecentric.com/news/08051105.htm http://www.sciencecentric.com/news/08051105.htm Sun, 11 May 2008 18:19:00 GMT Researchers at Columbia University Medical Centre have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioural and neuronal deficits associated with schizophrenia and possibly other brain disorders... http://www.sciencecentric.com/news/08051104.htm http://www.sciencecentric.com/news/08051104.htm Sun, 11 May 2008 17:00:00 GMT The COMT gene - known already for its role in schizophrenia - has been found to play a role in preeclampsia, according to a report in today's advance on-line issue of Nature.
