The new study examined the contribution of the olfactory system, the lateral line, and vision in odor source detection and localization in the smooth dogfish shark. The results, which appear in ...

For many insects, winter survival is in the genes

...aid David Denlinger, the study's lead author and a professor of entomology at Ohio State University. "Without these proteins, insects can't bear the cold and will ultimately die." Denlinger and his colleagues found nearly a dozen additional heat-shock proteins that are activated during diapause, a hibernati...

How brain pacemakers erase diseased messages

...ll, the study's lead investigator and an associate professor of biomedical engineering. "If you replace that instead with a constant 'pop-pop-pop-pop-pop-pop,' you've erased that pathological information." Grill said the high-frequency deep brain stimulation acts like a surgical lesion, another acceptable t...

Detecting cold, feeling pain: Study reveals why menthol feels fresh
