Swarms of locusts use social networking to communicate

July 15, 2011 8:48 am | News | Comments

The success of social networking sites has illustrated the importance of networking for humans; however for some animals, keeping informed about others of their kind is even more important. Researchers have shown that swarming, a phenomenon that can be crucial to an animal's survival, is created by the same kind of social networks that humans adopt.

Berkeley Lab lays foundation for 100 GBps prototype network

July 15, 2011 7:33 am | News | Comments

In its initial phase, the new $62 million Advanced Networking Initiative will connect the three DOE unclassified supercomputing centers. But it will lead to a nationwide 100 Gbps scientific network, and eventually a 1-terabit network connecting the Dept. of Energy’s exascale supercomputers.

Geo-immersion tech allows virtual travel in real time

July 11, 2011 1:11 pm | by Miles O’Brien | News | Comments

Upon first glance, USC’s Cyrus Shahabi’s maps contain the typical landmarks we've become accustomed to seeing on Yahoo or Google Maps. But a closer look reveals maps pulsing with images of moving cars, scenes of bustling people, and shifting colors of changing traffic patterns, all in real time. The concept of geo-immersion is beginning to blend the real and virtual worlds together.
