Fungus Fire Spores With 180,000 G Acceleration 69

Hugh Pickens writes "Although a variety of spore discharge processes have evolved among the fungi, those with the longest ranges are powered by hydrostatic pressure and include 'squirt guns' that are most common in the Ascomycota and Zygomycota. In these fungi, fluid-filled stalks that support single spores or spore-filled sporangia, or cells called asci that contain multiple spores, are pressurized by osmosis. Because spores are discharged at such high speeds, most of the information on launch processes from previous studies has been inferred from mathematical models and is subject to a number of errors, but now Nicholas Money, an expert on fungi at Miami University, has recorded the discharges with high-speed cameras at 250,000 frames-a-second and discovered that fungi fire their spores with accelerations up to 180,000 g, calling it 'the fastest flight in nature.' Money and his students, in a justified fit of ecstasy, have created a video of the first fungus opera."

Nobel Prize For Medicine Awarded, Physics Soon To Follow 135

Nobel Prize season is here again, and the first award for Physiology or Medicine was split between two virologists who discovered HIV and one who demonstrated that a virus causes cervical cancer. Coming soon is the announcement for Physics. Look to the right for a chance to pit your selection wit against the Royal Swedish Academy of Sciences with a poll for which scientific achievement deserves the prize. Front runners, according to Reuters, are; Andre Geim and Kostya Novoselov, discovers of graphene, Vera Rubin, provider of the best evidence yet of dark matter, and Roger Penrose and Dan Shechtman, discoverers of Penrose tilings and quasicrystals.

Do We Live In a Giant Cosmic Bubble? 344

Khemisty writes "Earth may be trapped in an abnormal bubble of space-time that is particularly void of matter. Scientists say this condition could account for the apparent acceleration of the universe's expansion, for which dark energy currently is the leading explanation. Until now, there has been no good way to choose between dark energy or the void explanation, but a new study outlines a potential test of the bubble scenario. If we were in an unusually sparse area of the universe, then things could look farther away than they really are and there would be no need to rely on dark energy as an explanation for certain astronomical observations. 'If we lived in a very large under-density, then the space-time itself wouldn't be accelerating,' said researcher Timothy Clifton of Oxford University in England. 'It would just be that the observations, if interpreted in the usual way, would look like they were.'"

Mars Lander Sees Falling Snow 118

Riding with Robots writes "NASA reports that the Phoenix Mars Lander has detected snow falling from Martian clouds. According to the Canadian team running a weather experiment, a laser instrument designed to study how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometers above the landing site. Data shows the snow vaporizing before reaching the surface, but one of the mission scientists said, 'We'll be looking for signs that the snow may even reach the ground.' Spacecraft soil experiments have also provided evidence of past interaction between minerals and liquid water."

Wal-Mart Ends DRM Support 231

An anonymous reader writes "So, you thought you did well to support the fledgling music industry by purchasing your tracks legally from the Wal-Mart store? Well, forget about moving these tracks to a new PC! Since they started selling DRM-free tracks last year, there's no money to be made in maintaining the DRM support systems, and in fact, support is being shut down. Make sure you circumvent the restrictions by burning the tracks to an old-fashioned CD before Wal-mart 'will no longer be able to assist with digital rights management issues for protected WMA files purchased from Walmart.com.' Support ends October 9th."

UK Gov't To Require ID Cards For Some Foreign Residents 216

craigavonite, writing "It's looking like the UK is in for biometric ID cards within the next few years, despite widespread protest from groups such as 'NO2ID,'" excerpts from an article at the BBC describing a UK identify card to be issued starting later this year: "The biometric card will be issued from November, initially to non-EU students and marriage visa holders. Home Secretary Jacqui Smith said the cards would allow people to 'easily and securely prove their identity.' Critics say the roll-out to some immigrants is a 'softening up' exercise for the introduction of identity cards for everyone."

Developers Will Get Windows 7 Alpha On Oct. 28 83

CWmike writes "Microsoft confirmed today that it will hand out 'pre-beta' release copies of Windows 7 on Oct. 28, at the Professional Developers Conference (PDC). Mike Swanson, a Microsoft technology evangelist, has said attendees will receive a 160GB external USB hard drive that will presumably include the Windows 7 alpha. Mike Cherry, an analyst with Directions on Microsoft, was cautiously optimistic that today's announcement meant Microsoft was on track with Windows 7. 'If they didn't do this, you would have to wonder if they could make the schedule,' Cherry said."

Quarter of Workers' Time Online Is Personal 248

sloit writes "Most people spend more than 25 per cent of their time online at work on personal activities. And 80 per cent of emails sent by volume in the workplace are personal. Bosses often have no way of tracking Internet activity or policies to define what staff can and cannot do. Paul Hortop, who reviews company network security for consultancy Voco, said the most common websites visited by personal web surfers were online trading sites, instant messaging/chat services and peer-to-peer sharing sites (allowing movie, music and software sharing)."

China To Run Out of IPv4 Addresses In 830 Days 619

JagsLive writes "China is running out of IP addresses unless it makes the switch to IPv6. According to the China Internet Network Information Center, under the current allocation speed, China's IPv4 address resources can only meet the demand of 830 more days and if no proper measures are taken by then, new Chinese netizens will not be able to gain normal access to the Internet. Li Kai, director in charge of the IP business for CNNIC's international department, says that if a netizen wants to get access to the Internet, an IP address will be necessary to analyze the domain name and view the pages. At present, most of the networks in China use IPv4 addresses. As a basic resource for the Internet, the IPv4 addresses are limited and 80% of the final allocation IP addresses have been used."

Germany Fired Up Over Clean Coal 385

MIT's Technology Review is reporting on the world's first coal-driven power plant designed to capture and store C02 emissions. "Vattenfall's small 30-megawatt plant burns the lignite in air from which nitrogen has been removed. Combustion in the resulting oxygen-rich atmosphere produces a waste stream of carbon dioxide and water vapor, three-quarters of which is recycled back into the boiler. By repeating this process, known as oxyfuel, it is possible to greatly concentrate the carbon dioxide. After particles and sulfur have been removed, and water vapor has been condensed out, the waste gas can be 98 percent carbon dioxide, according to Vattenfall. The separated carbon dioxide will be cooled down to -28 C and liquefied. Starting next year, the plan is to transport it by truck 150 miles northwest, to be injected 3,000 meters underground into a depleted inland gas field in Altmark. Ideally, in the future, the gas will be carried by pipeline to underground storage, says Vattenfall. "

Activision To "Monetize" Call of Duty Online Play 114

With Call of Duty: World at War set to hit store shelves this November, Activision has been making plans to monetize the online component of the game. "Infinity Ward-developed CoD4 has paid downloadable maps available on digital storefronts, but with CoD5, developed by Activision studio Treyarch, downloadable content will be a considerably bigger priority. Griffith added that Activision 'plans to increase online monetization' with CoD5, offering '3x the amount of content available for download and premium content called Day One Advantage.'" Activision also announced that for Call of Duty 6 they will be going back to Infinity Ward for development, the company who developed the first, second, and fourth offerings in the series. Treyarch made the third and fifth installments.

Hubble Finds Unidentified Object In Space 716

Gizmodo is reporting that the Hubble space telescope has found a new unidentified object in the middle of nowhere. Some are even suggesting that this could be a new class of object. Of course, without actually understanding more about it, the speculation seems a bit wild. "The object also appeared out of nowhere. It just wasn't there before. In fact, they don't even know where it is exactly located because it didn't behave like anything they know. Apparently, it can't be closer than 130 light-years but it can be as far as 11 billion light-years away. It's not in any known galaxy either. And they have ruled out a supernova too. It's something that they have never encountered before. In other words: they don't have a single clue about where or what the heck this thing is."
