Submission + - A day in the life of QuakeNet (vimeo.com)

Zarjazz writes: QuakeNet, the largest internet relay chat (IRC) Network in the world, has produced a very nice video of chat activity over a 24hour snapshot. How many of the users are really open proxies is left up to the opinions of the readers.

Submission + - Artificial Black Holes Made with Metamaterials

An anonymous reader writes: While our direct knowledge of black holes in the universe is limited to what we can observe from thousands or millions of light years away, a team of Chinese physicists has proposed a simple way to design an artificial electromagnetic (EM) black hole in the laboratory. In the Journal of Applied Physics, Huanyang Chen at Soochow University and colleagues have presented a design of an artificial EM black hole designed using five types of composite isotropic materials, layered so that their transverse magnetic modes capture EM waves to which the object is subjected. The artificial EM black hole does not let EM waves escape, analogous to a black hole trapping light. In this case, the trapped EM waves are in the microwave region of the spectrum.

Submission + - Yes Virginia, Pterosaurs Can Fly (sciencemag.org)

sciencehabit writes: Scientists had begun to doubt that pterosaurs (aka pterodactyls), the giant winged reptiles from the age of the dinosaurs, could fly. But a new study puts them back in the air. Unlike birds, which take off using only their puny hind legs, pterosaurs took off with all four of their limbs. With the added force of their much more powerful forelimbs, even giants like the thousand-pound Quetzalcoatlus could leave the ground. (Check out the cool video)

Submission + - Graphene Can be Made With Table Sugar (gizmag.com)

Zothecula writes: There’s no doubt that the discovery of graphene is one sweet breakthrough. The remarkable material offers everything from faster, cooler electronics and cheaper lithium-ion batteries to faster DNA sequencing and single-atom transistors. Researchers at Rice University have made graphene even sweeter by developing a way to make pristine sheets of the one-atom-thick form of carbon from plain table sugar and other carbon-based substances. In another plus, the one-step process takes place at temperatures low enough to make the wonder material easy to manufacture.
