...lattened and squeaking warnings. They relentlessly flick
their tails at one another until one of the adversaries comes to his scentses, gets the odiferous message and retreats. But until the research of Duke biologist Christine Drea and student Elizabeth Scordato, scientists had no idea what chemical me...
Researchers characterize a crucial family of signaling proteins in the human genome
...e movement of a phosphoryl group is similar to the flick
of a switch that causes a biochemical pathway go slower or faster. Kostich and his colleagues searched the publicly available sequence databases to find sequences with similarity to known protein kinase molecules. After removals of duplicates and pse...

of the antennule cleared it out and replaced it with another. Apparently, with each flick
of the antennule, a detailed map of the swirling filaments of odor in a plume is captured. Work is n...

antennules bearing tiny chemosensory hairs to sniff the water. "All of us in the biomechanics group are at the interface between biology and engineering," she said. "While engineers need to design structures to perform specific functions, we are stu...
