Submission + - Green Light For First European Whitespace Test Network Using Database (top10-digest.com)

An anonymous reader writes: Ficora, the Finnish equivalent of FCC gave green light for a coalition of academic and private enterprises to radiate in the so called whitespace bands. Whitespace radio spectrum designated for, but locally unused by TV-broadcasters.

Wireless industry expects whitespace to alleviate congestion of the airwaves.

Although prior whitespace tests have been carried out in Europe mainly in Cambridge, this is the first test in Europe that uses a geolocation database for frequency allocation.

Whitespace has been discussed previously on Slashdot here and here.

Submission + - SPAM: Oldest mites in amber discovered

AlfonAri writes: "230-million-year-old fossils push back date of resin-preserved arthropods write: By Meghan Rosen — Mites could give competitors on Survivor a run for their game-show money. Two of the tiny creatures, trapped in fossilized tree resin, smash the record for ancient amber-preserved arthropods, a group of critters that includes beetles, butterflies, spiders and shrimp. At 230 million years old, the mite fossils are about 100 million years older than previous finds, and suggest that mites’ basic body blueprint may be built to outwit, outplay and outlast. “Dinosaurs have come and gone, but mites have hardly changed,” says David Grimaldi of the American Museum of Natural History in New York City. “Their body form is quite similar to what we see in gall mites today.”"

'Death Star' Aimed at Earth 400

An anonymous reader writes "A spectacular, rotating binary star system is a ticking time bomb, ready to throw out a searing beam of high-energy gamma rays that could lead to a major extinction event — and Earth may be right in the line of fire. Australian science magazine Cosmos Magazine reports: 'Though the risk may be remote, there is evidence that gamma ray bursts have swept over the planet at various points in Earth's history with a devastating effect on life. A 2005 study showed that a gamma-ray burst originating within 6,500 light years of Earth could be enough to strip away the ozone layer and cause a mass extinction. Researchers led by Adrian Melott at the University of Kansas in Lawrence, U.S., suggest that such an event may have been responsible for a mass extinction 443 million years ago, in the late Ordovician period, which wiped out 60 per cent of life and cooled the planet.'"
