p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter distribution should look like near the Sun where we might stand a chance of detecting it.'" We discussed a related simulation a few months ago.

Smivs writes "Bletchley Park, the home to the allied codebreakers during WWII, and a major computing heritage centre, has been given a financial lifeline, reports the BBC. The grant of £330,000 will be used to undertake urgent roof works as the rooms of the Grade II-listed mansion, replete with painted ceilings, timber panelling, and ornate plasterwork, are at risk because the roof has been patched rather than renovated so many times during the 130 years of the mansion's history. The donation follows efforts to highlight the dilapidated state of the huts and other buildings at Bletchley. Discussions are also in progress on a further three-year, £600,000 funding programme for the historic site. 'Bletchley Park played a fundamental role in the Allies winning the Second World War and is of great importance to the history of Europe,' said Dr Simon Thurley, chief executive of English Heritage."

coondoggie writes "Nine rocket-powered vehicles will compete for NASA's $2 million, 2008 Northrop Grumman Lunar Lander Challenge, Oct. 24-25. The goal is to accelerate development of commercial Lunar Landers capable of bringing payloads or humans back and forth between lunar orbit and the lunar surface. NASA of course would expect to use some of the technology developed at the Challenge. To win the prize, teams must demonstrate a rocket-propelled vehicle and payload that takes off vertically, climbs to a defined altitude, flies for a pre-determined amount of time, and then land vertically on a target that is a fixed distance from the launch pad. After landing, the vehicle must take off again within a pre-determined time, fly for a certain amount of time and then land back on its original launch pad." Details about the teams involved with the competition are available at the X-Prize website. The event will be broadcast live via webcast next weekend.

Ruler of Planets writes "PlanetX64 has just published an article on loading OS X on an MSI Wind, effectively creating a machine that is smaller and lighter than a Macbook Air. The exercise was done solely for academic purposes and doing so voids all kinds of warranties, but hey, now you can slip a Mac into a lab coat pocket!"

RATLSNAKE writes "The heads of some of the most popular Australian ISPs were all interviewed over at ZDNet about Net Neutrality. For once, they all seem to agree, and they say it's a problem with the US business model, or the lack thereof. They discuss why they don't think it's an issue in Australia. Simon Hackett, the managing director of Adelaide-based ISP Internode, had this to say: 'The [Net neutrality] problem isn't about running out of capacity. It's a business model that's about to explode due to stress. ... The idea that the entire population can subsidize a minority with an extremely high download quantity actually isn't necessarily the only way to live.' Of course, this also explains why we Australians do not have truly unlimited plans."

I Don't Believe in Imaginary Property writes "The database used by the government to generate lists like the No-Fly List is 'crippled by technical flaws,' according to the chairman of a House technology oversight subcommittee. And the upgrade may be worse than the original. Rep. Brad Miller (D-NC) says that 'if actually deployed, [the upgrade] will leave our country more vulnerable than the existing yet flawed system in operation today.' It seems that the current database doesn't have any easy way to do plain-text matching, forcing users to enter SQL queries. That might not sound so bad until you learn that the database contains 463 poorly indexed tables. How long until there's a terrorist named Robert'); DROP DATABASE; —?"

Not so very long ago after passengers were left hanging by a similar glitch at LAX, Gilby4mPuck writes with another story of NIC failure leading to a disruption of air traffic, this time in Ireland, excerpting: "Data showing the location, height and speed of approaching planes disappeared from screens for 10 minutes each time. ... Thales ATM stated that in 10 similar air traffic control Centres worldwide with over 500,000 flight hours (50 years), this is the first time an incident of this type has been reported. ... '[They] confirmed the root cause of the hardware system malfunction as an intermittent malfunctioning network card which consequently overcame the built-in system redundancy,' said an IAA spokeswoman."

akutz writes "I've had the flu since Tuesday afternoon. My wife picked me up from work with a temperature of 103.6 and it finally broke at 98.7 around 3am this morning. Yay. The problem is that I used my laptop during my periods of feverish deliriousness, contaminating my shiny 15" MacBook Pro with the icky influenza virus. I am asking my fellow Slashdotters if they have ever sought out a good way of disinfecting their lucky laptops after an illness. Do you use soap? A light acid bath? Just get the family dog to lick it until it looks clean?"

An anonymous reader writes "After trying to charge $167,488 for their collection of county tax maps (in TIF format), West Virginia was forced by a judge to hand them over for a $20 'reproduction costs' fee. Now a county tax assessor has filed a lawsuit trying to block the tax maps from being put online, claiming copyright infringement and financial damages since fewer people are coming to her to buy paper copies at $8 per page."

Weather Storm brings us an InformationWeek article about Wal-Mart's push for suppliers to RFID tag their product shipments. Wal-Mart seems to have lost patience in waiting for its suppliers to adopt the inventory tracking initiative. From InformationWeek: "The retailer says that beginning Jan. 30, it will charge suppliers a $2 fee for each pallet they ship to its Sam's Club distribution center in Texas that doesn't have an RFID tag. The charge is to cover Sam's Club's cost to affix tags on each pallet, says a Wal-Mart spokesman. The retailer hasn't taken such a strong-arm approach yet with the more than 15,000 suppliers that still haven't complied with its request to tag pallets and cases headed for its Wal-Mart stores. Instead, it seems focused on turning its 700-store Sam's Club warehouse-outlet division into an example of RFID supply chain technology in action, down to requiring item-level RFID in 22 distribution centers by 2010."

eldavojohn sends us an article about a discovery by Carnegie Mellon researchers that explains why repetitive studying or training is effective. Previous research had suggested the opposite, which ran counter to nearly everyone's personal experience. Scientists hope that this information will help us to learn more about diseases which affect the memory, such as Alzheimer's. From the article: "In a series of experiments the researchers blocked different receptors, including NMDA, to see the receptors' effect on long-term neural stimulation. They found that while the NMDA receptor is required to begin neural strengthening, a second neurotransmitter receptor -- the metabotropic glutamate (mGlu) receptor -- comes into play after this first phase of cellular learning. ...blocking mGlu receptors caused strengthening to stop."
