prostoalex writes "The bionic arm project sponsored by DARPA is nearing completion, and might undergo clinical trials. 'The arm has motor control fine enough for test subjects to pluck chocolate-covered coffee beans one by one, pick up a power drill, unlock a door, and shake a hand. Six preconfigured grip settings make this possible, with names like chuck grip, key grip, and power grip. The different grips are shortcuts for the main operations humans perform daily.'"

An anonymous reader writes "According to CNET.co.uk, certain new Dell laptops with a brushed-aluminum finish are giving users more than they bargained for. 'We know this because several CNET staff were hit with an electrical charge while using Dell's new XPS M1530 — and we're not the only ones. Dell's forums are littered with user complaints about the shocking experiences they've had with some systems. The problem only seems to occur in Dell laptops that have a brushed-aluminum finish. These include the XPS M1330 and XPS M1530. It's caused by the two-pronged connection between the mains lead and the power adapter, which isn't earthed properly because of its lack of a third pin. The laptop therefore exhibits an electrical potential (voltage) between its exposed metal parts (the brushed aluminum wrist pad) and earth ground. Since there is no earth, the human body basically acts as a wire that can conduct electric current, hence the tingling, jolting sensation.'"

Popular in Victorian and Steampunk fantasies, airships and zeppelins evoke a certain elegance that most modern travelers don't associate with the airplane. Some companies are capitalizing on that idea, and a need to move cargo by air in an era of ever-increasing fuel costs, to re-re-introduce commercial zeppelins. Popular Mechanics notes four notable airship designs, all with specific design purposes. One craft in particular, the Aeroscraft ML866, is being funded by the US government's DARPA group. It looks to combine the best elements of the helicopter and the zeppelin. "The Aeroscraft ML866's potentially revolutionary Control of Static Heaviness system compresses and decompresses helium in the 210-ft.-long envelope, changing this proposed sky yacht's buoyancy during takeoff and landings, Aeros says. It hopes to end the program with a test flight demonstrating the system. "

Selikoff writes "NASA's Voyager 2 spacecraft has found that our solar system is not round but is 'dented' by the local interstellar magnetic field, space experts said on Monday. The data were gathered by the craft on its 30-year journey when it crossed into a region called the 'termination shock.' The data showed that the southern hemisphere of the solar system's heliosphere is being pushed in. Voyager 2 is the second spacecraft to enter this region of the solar system, behind Voyager 1, which reached the northern region of the heliosheath in December 2004."

theodp writes "PC Magazine's John C. Dvorak has a unique take on the cute One Laptop per Child XO-1, deeming the OLPC project a naive fiasco waiting to unfold that sends an insulting 'let them eat cake' message to the world's poor. When it comes down to a choice of providing African kids living in absolute poverty with access to Slashdot or a $200 truckload of rice, Dvorak votes for the latter. Buy ten OLPCs if it assuages your guilt, says Dvorak, but 'I'll donate my money to hunger relief.'"

theodp writes "It took nearly a decade, but Google has done a turnabout and is honoring Veterans Day with a special holiday design for its famous logo. Users who log onto Google's home page are greeted with three World War I-era helmets capping the letters 'o' and 'e' in Google's name. The decoration is a marked departure for the company, which has come under fire from veterans' groups for ignoring American holidays such as Veterans Day and Memorial Day since Google's inception in 1999."

eldavojohn writes "Hundreds of black holes that were thought to exist at the beginning of the universe have been found by NASA's Spitzer and Chandra space telescopes. From the article, 'The findings are also the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths building monstrous black holes at their cores. For decades, a large population of active black holes has been considered missing. These highly energetic structures belong to a class of black holes called quasars. A quasar consists of a doughnut-shaped cloud of gas and dust that surrounds and feeds a budding supermassive black hole. As the gas and dust are devoured by the black hole, they heat up and shoot out X-rays. Those X-rays can be detected as a general glow in space, but often the quasars themselves can't be seen directly because dust and gas blocks them from our view.' This is pretty big, as it's empirical evidence proving the existence of objects that theoretically had to exist but could not be detected previously."

eldavojohn writes "Researchers have created an electronic nose that can detect odor and identify which odors are a concern to it. From the article, 'The Lewis Group a division of Chemistry and Chemical Engineering at Caltech have a working model of an electronic nose. The efforts of Caltech scientists has led to an array of simple, readily fabricated chemically sensitive conducted polymer film. An array of broadly-cross reactive sensors respond to a variety of odors. However, the pattern of differential responses across the array produces a unique pattern for each odorant. The electronic nose can identify, classify and quantify when necessary the vapor or odor that poses a concern or threat.'"

An anonymous reader writes "Commtouch released its Email Threats Trend Report based on the automated analysis of billions of email messages weekly. The report examines the appearance of new kinds of attachment spamsuch as PDF spam and Excel spam together with the decline of image spam, as well as the growing threat of innocent appearing spam containing links to malicious web sites. Image spam declined to a level of less than 5% of all spam, down from 30% in the first quarter of 2007; also, image pump-and-dump spam has all but disappeared, with pornographic images taking its place."

Recently at my university where I'm a student and a sys admin, we have been experiencing some odd outages, in particular since the 25th of September. The outages seemed to occur between 8 PM and 12:00 AM — peak gaming hours for our dorms. It just happens that Halo 3 came out on the 25th of September. Upon further investigation we found that our network routers were shaping TCP packets, but not UDP. Once we applied UDP shaping as well, all network outages ceased. Gamers complained, but university students attempting to access network resources such as our UNIX clusters were satisfied.

Hugh Pickens writes "Algae has long been known as a promising source of biodiesel. It's worth noting, though, that algae also produces a small amount of hydrogen during photosynthesis. The MIT Technology Review reports that researchers have created a mutant algae that makes better use of sunlight to increase the amount of hydrogen that the algae produce. Anastasios Melis and his team at the University of California have manipulated the genes that control the amount of chlorophyll in the algae's chloroplasts. Although the process is still at least five years from being used for hydrogen generation, Melis estimates that if 50% of the algae's photosynthesis could be directed toward hydrogen production, an acre could produce 40 kilograms of hydrogen per day. At the price of $2.80 a kilogram, hydrogen could compete with gasoline, since a kilogram of hydrogen is equivalent in energy to a gallon of gasoline."

KSobby writes "The organization that I work for is going to be redoing our website in .Net/AJAX. On the site, our members will have profile pages listing where their organizations are located (our members are scattered throughout the world) as well as other pertinent information for the general public. It is a non-profit organization, so funds are tight. My question to you: If we include maps, which API do we go with: Google or Microsoft? We're in a Microsoft environment (we're non-profit and Microsoft basically gives us everything for free) but the ubiquity of Google may be enough to sway us. Has anyone used either extensively? Used them in conjunction with .Net?"

An anonymous reader writes to mention that even though Web 2.0 is just now starting to gain widespread acceptance, there are those who are already trying to hijack the term Web 3.0. According to Gartner, there are quite a few new technologies and incremental modifications to existing Web 2.0 technology, but nothing that could equal the level of fundamental change exhibited by the shift to Web 2.0.
