Stars Can Be StrangeAs per the "Strange Matter Hypothesis," which gained popularity in the paranormal 1980's, nuclear matter, too, can be strange. The hypothesis suggests that small conglomerations of quarks, the infinitesimally tiny particles that attract by a strong nuclear force to form neutrons and protons in atoms, are the true ground state of matter. The theory has captivated particle physicists worldwide, including one of Washington University's own.

Frankincense Trees Overexploited For Christmas ScentCurrent rates of tapping frankincense - which according to the Bible was given to the baby Jesus by the three wise men at Christmas and which will feature in thousands of Nativity plays in coming days - are endangering the fragrant resin's sustained production, ecologists have warned. Writing in the recent issue of Journal of Applied Ecology, ecologists from the Netherlands and Eritrea say that over tapping the trees results in them producing........Go to the My-media-blog (Added on 12/18/2006 4:55:48 AM)
Ebola-Outbreak Kills 5000 GorillasSince reports of ape die-offs first circulated widely in 2003, sceptics have doubted how large these die-offs were and whether Ebola was even the cause. The new study, led by Magdalena Bermejo of the University of Barcelona, allays these doubts because it was conducted in a closely monitored gorilla population where genetic tests confirmed Ebola as the cause of death.

Scientists Make Liquid Crystal DiscoveryWhat do milk, paint, ink and liquid crystals have in common? Colloids. Findings of Kent State University scientists indicate that manipulating the size of colloids, micron-sized or nanometer-sized particles, can produce huge changes in the material properties of liquid crystals.

Identification of carbon dioxide receptors in insectsMosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis. Now, reporting in today's advance online publication in Nature, Leslie Vosshall's laboratory at Rockefeller University has identified the two molecular receptors in fruit flies that........Go to the Science-blog (Added on 12/13/2006 8:01:12 PM)
