Spectrum of Light Captured From Distant World 32

An anonymous reader writes with this excerpt from Cosmos: "Astronomers have made the first direct capture of a spectrum of light from a planet outside the Solar System and are deciphering its composition. The light was snared from a giant planet that orbits a bright young star called HR 8799 about 130 light-years from Earth, said the European Southern Observatory (ESO). ... The find is important, because hidden within a light spectrum are clues about the relative amounts of different elements in the planet's atmosphere. 'The features observed in the spectrum are not compatible with current theoretical models,' said co-author Wolfgang Brandner. 'We need to take into account a more detailed description of the atmospheric dust clouds, or accept that the atmosphere has a different chemical composition from that previously assumed.' The result represents a milestone in the search for life elsewhere in the universe, said the ESO. Until now, astronomers have been able to get only an indirect light sample from an exoplanet, as worlds beyond our Solar System are called. They do this by measuring the spectrum of a star twice — while an orbiting exoplanet passes near to the front of it, and again while the planet is directly behind it. The planet's spectrum is thus calculated by subtracting one light sample from another."

No Naked Black Holes 317

Science News reports on a paper to be published in Physical Review Letters in which an international team of researchers describes their computer simulation of the most violent collision imaginable: two black holes colliding head-on at nearly light-speed. Even in this extreme scenario, Roger Penrose's weak cosmic censorship hypothesis seems to hold — the resulting black hole (after the gravitational waves have died down) retains its event horizon. "Mathematically, 'naked' singularities, or those without event horizons, can exist, but physicists wouldn't know what to make of them. All known mechanisms for the formation of singularities also create an event horizon, and Penrose conjectured that there must be some physical principle — a 'cosmic censor' — that forbids singularity nakedness ..."

Radiation Absorbing Mineral Found In the Arctic 351

An anonymous reader writes "A mineral has recently been found that exhibits the astounding property of being able to remove radiation from water-based solutions. 'After coming into contact with the mineral, radioactive water becomes completely safe. Had this mineral been available to physicists after the Chernobyl or Three Mile Island disasters, the consequences might have been very different, as both accidents resulted in contamination from radioactive water.' Also, the article notes that although only grams of the material have been found, tons of it are needed; they are confident they could artificially reproduce it."

AT&T Arbitration Clause Ruled Unconscionable 261

Tech.Luver writes to tell us the Consumerist is reporting that a small clause in AT&T contracts has been ruled "unconscionable" by the 9th circuit court of appeals. The clause in question stated that if you use AT&T service you surrender your right to class action lawsuits and instead have to participate in mandatory binding arbitration.

High-Tech Squirrels Trained to Conduct Espionage 269

Pcol writes "In the July 20 issue of the Washington Post, columnist Al Kamen reports that the BBC has translated a story headlined 'spying squirrels,' published in the Iranian newspaper Resalat on the use of trained animals to conduct espionage against their country: 'A few weeks ago, 14 squirrels equipped with espionage systems of foreign intelligence services were captured by [Iranian] intelligence forces along the country's borders. These trained squirrels, each of which weighed just over 700 grams, were released on the borders of the country for intelligence and espionage purposes.' According the story the squirrels had 'GPS devices, bugging instruments and advanced cameras' in their bodies. 'Given the fast speed and the special physical features of these animals, they provide special capabilities for spying operations. Once the animals return to their place of origin, the intelligence gathered by them is then offloaded. . . .' Iranian police officials captured the squirrels before they could carry out their assignments."

Airships to Patrol Venezuela's Skies 451

bprime writes "The BBC reports that officials in the Venezuelan capital, Caracas, have bought three airship UAVs to keep tabs on the local populace. From the article: 'The 15 metre (49 foot) long air ships are emblazoned with government slogans. Written in bright red are the words, We watch over you for your security.' They're not exactly black helicopters, but how long do you think until we see similar measures in high-crime American cities?"

Dept. of Energy Rejects Corn Fuel Future 596

eldavojohn writes "The United States' Department of Energy is stating that corn based fuel is not the future. From the article, "I'm not going to predict what the price of corn is going to do, but I will tell you the future of biofuels is not based on corn," U.S. Deputy Energy Secretary Clay Sell said in an interview. Output of U.S. ethanol, which is mostly made from corn, is expected to jump in 2007 from 5.6 billion gallons per year to 8 billion gpy, as nearly 80 bio-refineries sprout up. In related news, Fidel Castro is blasting the production of corn fuel as a blatant waste of food that would otherwise feed 3 billion people who will die of hunger."

Two Snowflakes May Be Alike After All 180

An anonymous reader writes "LiveScience is reporting that it may be possible for two snowflakes to be alike after all. For anyone who studies probability, this seems reasonable, given that the article mentions that 10^24 snowflakes fall in any given year. The article contains links to fascinating snowflake pictures. From the article: 'A typical snow crystal weighs roughly one millionth of a gram. This means a cubic foot of snow can contain roughly one billion crystals ... "It is probably safe to say that the possible number of snow crystal shapes exceeds the estimated number of atoms in the known universe," Nelson said. Still, while "no two snowflakes are alike" might hold true for larger snowflakes, Nelson figures it might ring false for smaller crystals that sometimes fall before they have a chance to fully develop. "How likely is it that two snowflakes are alike? Very likely if we define alike to mean that we would have trouble distinguishing them under a microscope and if we include the crystals that hardly develop beyond the prism stage--that is, the smallest snow crystals," Nelson said.'"

Parasites Makes Us Dumber or Sexier 240

odie_q writes "It has long been known that the Toxoplasma gondii parasite alters its host's behavior, but now it seems the way it alters it depends on the sex of the host. From the article: 'A common parasite can increase a women's attractiveness to the opposite sex but also make men more stupid, an Australian researcher says ... Infected men have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women. On the other hand, infected women tend to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls.'"
