A Japanese research team has found a material that could be used to make a low-price super disc with data storage capacity thousands of times greater than a DVD, the lead scientist said Monday. The material transforms from a black-colour metal state that conducts electricity into a brown semiconductor when hit by light, according to Shin-ichi Ohkoshi, chemistry professor at the University of Tokyo.The material, a new crystal form of titanium oxide, can switch back and forth between the metal and semiconductor states at room temperature when exposed to light, creating an effective on-off function for data storage.
It is "promising as a material for a next-generation optical storage device," Ohkoshi told AFP by telephone.

http://www.cbsnews.com/stories/2010/05/25/tech/main6518049.shtml(AP) Plunging into the waters off Alexandria Tuesday, divers explored the submerged ruins of a palace and temple complex from which Cleopatra ruled, swimming over heaps of limestone blocks hammered into the sea by earthquakes and tsunamis more than 1,600 years ago.
The international team is painstakingly excavating one of the richest underwater archaeological sites in the world and retrieving stunning artifacts from the last dynasty to rule over ancient Egypt before the Roman Empire annexed it in 30 B.C.
Using advanced technology, the team is surveying ancient Alexandria's Royal Quarters, encased deep below the harbor sediment, and confirming the accuracy of descriptions of the city left by Greek geographers and historians more than 2,000 years ago.

http://www.livescience.com/animals/funnel-nosed-fossil-100526.htmlIt's not the mythical kraken, but an ancient creature belonging to the largest, nimblest and probably smartest group of invertebrates has jumped out of the fossil record with a different identity than previously thought. That finding restructures a branch on the evolutionary tree.The tiny mysterious fossil of Nectocaris pteryx — previously described as a shrimp with a chordate tail — is neither a shrimp (an arthropod) nor a chordate (vertebrates and their nearest relatives), but a mollusk, according to a new study detailed in the May 27 issue of the journal Nature.
