Tracing Origins Of Critical Step In Animal Evolution — The Development Of Nerves:

University of Queensland researchers have traced the origins of one of the most important steps in animal evolution – the development of nerves.

Future Impact Of Global Warming Is Worse When Grazing Animals Are Considered, Scientists Suggest:

The impact of global warming in the Arctic may differ from the predictions of computer models of the region, according to a pair of Penn State biologists. The team — which includes Eric Post, a Penn State associate professor of biology, and Christian Pederson, a Penn State graduate student — has shown that grazing animals will play a key role in reducing the anticipated expansion of shrub growth in the region, thus limiting their predicted and beneficial carbon-absorbing effect.

One Sleepless Night Increases Dopamine In The Human Brain:

ust one night without sleep can increase the amount of the chemical dopamine in the human brain, according to new imaging research in the August 20 issue of The Journal of Neuroscience. Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep.
