Dead Zone Fish Change Sexes

Dead Zone Fish Change Sexes

A low-oxygen "dead zone" in the Gulf of Mexico (map) is causing sexual deformities in fish, a new study says. The Gulf dead zone occurs when agricultural and waste runoff from the Mississippi River spark blooms of algae and microbes. These organisms gobble up oxygen, starving other marine lif

Human brain’s ‘bat sight’ found

The part of the brain used by people who can "see like a bat" has been identified by researchers in Canada. Some blind people have learned to echolocate by making clicking noises and listening to the returning echoes. A study of two such people, published in PLoS ONE, showed a part of the bra
