Tiny roundworms called Caenorhabditis elegans have a rather uncomplicated method for finding food: They wriggle and turn and explore new territory until they find something edible, and then they stay the course until the food disappears. But despite the worm's simple nervous system, researchers have been unable to figure out exactly how a stimulus such as food odor gets converted into a more complex, long-lasting behavior like foraging. Now, using tools borrowed from the computer industry, Rockefeller University researchers have created tiny devices that allow them to watch in real time as information travels from one worm neuron to another. Their findings - that one of the long-studied olfactory neurons has a totally different mode of operation than expected - uncover a surprising similarity between the worm's neural network and our own.

 | 38-year-old researcher Kasper Thorup, University of Copenhagen, has come a step closer to unravelling the secret of how migration birds navigate across large distances. He has followed the birds' passage across USA from small sports planes. The results are now being published in the scientific journal PNAS. ...> Full Article |
 | Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. When seen in the lab, they are nothing like the long upper arm bones of any other mammal, says Samantha Hopkins, a paleontologist at the University of Oregon. ...> Full Article |
