New tests for Russian stealth fighterMOSCOW - The T-50, Russia's fifth-generation stealth fighter, has completed initial approach trials to a refueling aircraft, manufacturer Sukhoi said Tuesday. The refueling trials come as Sukhoi's first prototype, T-50-1, undertakes preparations for a flight test program involving flight at super-critical angles of attack and maneuverability, Russian news agency RIA Novosti reported. In August, T-50-3 will start full tests of the aircraft's new active phased-array radar system and avionics that the company said has shown impressive results in air-to-air and ground-to-air tests. The T-50 is to enter Russian air force service after 2015.
Greenhouse gas seen as risk to marine lifeLIVERMORE, Calif. - Many marine species will be harmed or won't survive if carbon dioxide level increases persist in the world's oceans, U.S. and Australian researchers say. The scientists argue current protection policies and management practices are unlikely to be enough to save the species. They say unconventional, non-passive methods to conserve marine ecosystems need to be considered if various marine species are to survive. A significant amount of carbon dioxide released into the atmosphere is taken up by the oceans in a form that makes the ocean more acidic. The increasingly acidic conditions have been shown to be harmful to many species of marine life, especially corals and shellfish. Scientists from the University of California, Santa Cruz, the Lawrence Livermore National Laboratory, The Nature Conservancy in Hawaii and the University of Queensland in Australia said current policies are unlikely to solve the problem. "Our concern is that the specific actions to counter such impacts as identified in current policy statements will prove inadequate or ineffective," the researchers wrote in the journal Nature Climate Change. "A much broader evaluation of marine management and mitigation options must now be seriously considered," they wrote. Policy makers should solicit and evaluate all potential marine management strategies, including unconventional ones, to prevent further environmental degradation, they said.
Britain gives go-ahead to 4G InternetLONDON - Britain's largest mobile operator can re-purpose its existing spectrum licenses to give the country its first 4G high-speed Internet service, regulators said. Everything Everywhere, formed by the merger of Orange and T-Mobile in 2010, has a surplus of 2G spectrum and applied to Britain communications regulator Ofcom last autumn to reuse some of the spectrum for 4G to create a network that can offer downloads 10 times faster than its 3G network. Ofcom has agreed Everything Everywhere can begin 4G service Sept/ 11, The Daily Telegraph reported. Rival networks like O2 and Videophone, who will have to bid for new spectrum licenses later this year, had opposed Everything Everywhere's spectrum reuse plans but Ofcom ruled the benefits to consumers of having 4G services available sooner outweighed claims it would give Everything Everywhere an unfair advantage. The ruling "will deliver significant benefits to consumers, and there is no material risk that those benefits will be outweighed by a distortion of competition," Ofcom said. Vodafone, however, was critical of Ofcom's decision in favor of Everything Every where's plan. "The regulator has shown a careless disregard for the best interests of consumers, businesses and the wider economy through its refusal to properly regard the competitive distortion created by allowing one operator to run services before the ground has been laid for a fully competitive 4G market," a Vodafone spokesman said.
Uranium from seawater said attainable goalPHILADELPHIA - U.S. scientists say they're making progress towards a 40-year-old dream of extracting uranium for nuclear power from seawater. "Estimates indicate that the oceans are a mother lode of uranium, with far more uranium dissolved in seawater than in all the known terrestrial deposits that can be mined," researcher Robin D. Rogers of the University of Alabama told a meeting of the American Chemical Society in Philadelphia. "The difficulty has always been that the concentration is just very, very low, making the cost of extraction high. But we are gaining on that challenge." An economic analysis done for the U.S. Department of Energy comparing seawater extraction of uranium to traditional ore mining shows DOE-funded technology now can extract about twice as much uranium from seawater as the first methods, developed in Japan in the late 1990s. That brings production costs down to around $300 per pound of uranium, from a cost of $560 per pound using the Japanese technology, although extraction from seawater remains about five times more expensive than uranium mined from the ground, researchers said. However, the researchers said, the current goal is not to make seawater extraction as economical as terrestrial mining but to establish uranium from the ocean as a sort of "economic backstop" that will ensure there will be enough uranium to sustain nuclear power through the 21st century and beyond. "This uncertainty around whether there's enough terrestrial uranium is impacting the decision-making in the industry, because it's hard to make long-term research and development or deployment decisions in the face of big uncertainties about the resource," Erich A Schneider of the University of Texas at Austin said. "So if we can tap into uranium from seawater, we can remove that uncertainty."
