On Earth, we tend to find dust nothing more than a nuisance that blankets our furniture and causes us to sneeze. Cosmic dust can also be a hindrance to astronomers because cameras using visible light cannot see through it. However, studying cosmic dust in detail helps astronomers to pin down the ingredients of the raw mixture that eventually gives birth to stars. http://www.physorg.com/news178899301.html Space & Earth Tue, 01 Dec 2009 14:16:51 EST news178899301 Antennas aren't just for listening to the radio anymore. They're used in everything from cell phones to GPS devices.

A large proportion of all species are "carnivorous," meaning that they are generalist predators feeding on other small animals or scavenging on their remains. Some, however, are "herbivorous". http://www.physorg.com/news178893395.html Biology Tue, 01 Dec 2009 12:37:42 EST news178893395 Even the anticipation of sweets may cause our muscles to start taking up more blood sugar, say researchers reporting in the December issue of Cell Metabolism.
