Roland Piquepaille writes "Physicists from the University of Illinois at Urbana-Champaign (UIUC) say they have improved the performance of solar cells by 60 percent. And they obtained this spectacular result by using a very simple trick. They've coated the solar cells with a film of 1-nanometer thick silicon fluorescing nanoparticles. The researchers also said that this process could be easily incorporated into the manufacturing process of solar cells with very little additional cost.

Thermite writes "On March 6, 2006 an accident occurred at Nuclear Fuel Services in Erwin, Tennessee. According to reports, almost 9 gallons of highly enriched uranium in solution spilled and nearly went into a chain reaction. Before the accident in 2004, the NRC and The Office of Naval Reactors had changed the terms of the company's license so that any correspondence with Nuclear Fuel Services would be marked 'official use only.' From the article: 'While reviewing the commission's public Web page in 2004, the Department of Energy's Office of Naval Reactors found what it considered protected information about Nuclear Fuel Service's work for the Navy. The commission responded by sealing every document related to Nuclear Fuel Services and BWX Technologies in Lynchburg, Va., the only two companies licensed by the agency to manufacture, possess and store highly enriched uranium.' The result was that the public and Congress were both left in the dark for 13 months regarding this accident and other issues at the facility."

A study done by the market research firm Parks Associates shows that online games are the biggest draw for internet-based entertainment. Online games, including MMOGs, casual games, and free-to-play virtual worlds, had a bigger draw even that social networking sites or YouTube. Some 34% of US internet consumers played online games at least once a week in the second quarter of 2007. "Furthermore, the number of people playing games online seems to be growing by leaps and bounds. Parks' research found that the year-over-year growth rate for frequent online gamers was 79 percent, which easily trumps the growth rate for users of social networking (46 percent). That said, the growth rate for frequent users of video streaming sites was a whopping 123 percent, and that 'could pose a significant challenge to the gaming industry in capturing the online leisure time of Internet users,' Parks cautioned."

coondoggie writes "Internet service providers in the US experienced a service slowdown Monday after fiber-optic cables near Cleveland were apparently sabotaged by gunfire. TeliaSonera AB, which lost the northern leg of its US network to the cut, said that the outage began around 7 p.m. Pacific Time on Sunday night. When technicians pulled up the affected cable, it appeared to have been shot up over a length of a kilometer. 'Somebody had been shooting with a gun or a shotgun into the cable,' said a TeliaSonera spokesman. The company declined to name the service provider whose lines had been cut, but a source familiar with the situation said the lines are owned by Level 3 Communications Inc. Level 3 could not be reached for comment."

eldavojohn writes "Researchers reported the first genome transplant from one bacterium to another, thereby transforming the species from M. mycoides to M. capricolum. The research, published in Science, shows that it is possible to achieve a success rate of 1 in 150,000 genome transplants in bacteria. While this may not seem like very good odds, it's actually a major step towards synthetic life, opening up the possibility of tailoring bacteria to our needs. The article mentions medical uses and fuel production as possible applications."

modapi writes "According to the EPA, data centers — not including Google et al. — are on track to double power consumption in the next five years, to 3% of the US energy budget. That is a lot of expensive power. Can we cut the power requirement? We could, if we had a reliable way to benchmark power consumption across architectures. Which is what JouleSort: A Balanced Energy-Efficiency Benchmark (PDF), by a team from HP and Stanford, tries to do. StorageMojo summarizes the key findings of the paper and contrasts it with the recent Google paper, Power Provisioning for a Warehouse-sized Computer (PDF). The HP/Stanford authors use the benchmark to design a power-efficient server — with a mobile processor and lots of I/O — and to consider the role of software, RAM, and power supplies in power consumption."

F4_W_weasel sends us to the BBC for news of the eighth lone neutron star ever discovered. It has no associated supernova remnant, binary companion, or radio pulsations. It's in our stellar neighborhood, at most 1,000 light years away. The object emits all its radiation (as far as wa can detect with current instruments) in X rays. The object is called Calvera, after the bad guy in The Magnificent Seven — which is itself the collective nickname for the seven such objects previously known.
