+ - Ask Slashdot: how to verify your identity without being there in person? 1

Submitted by united_notions
united_notions (916092) writes "I work for a large university, and our recruitment policy allows us to interview prospective staff and grad students over Skype, but the chosen applicant still has to show up in person before they can be formally appointed. This is so that they can physically hold up a genuine passport and prove their identity (as a failsafe against bogus interviews). What other ways could applicants do this, without flying potentially around the world just to file paperwork?"

+ - Sharkskin May Be Next Innovation in Swimwear->

Submitted by sciencehabit
sciencehabit (1205606) writes "Researchers have used a 3D printer to replicate the properties of sharksin. Sharkskin is as rough as high grain sandpaper thanks to millions of small toothlike scales called denticles. Grooves along these denticles smooth the flow of passing water, giving swimming sharks a boost. Using the printer, the team studded thousands of identical 2-millimeter denticles onto both sides of a flexible foil. In slow-flowing water, the denticles reduced drag on the foil by 8.7%; the benefits were even more pronounced when the robotic arm mimicked a swimming motion, the team reports, with a 6.6% increase in swimming speed and a 5.9% reduction in energy expenditure. The researchers believe the material could one day be used in speed-boosting swimsuits, though they admit major manufacturing challenges could leave the idea dead in the water."

Submitted by sciencehabit
sciencehabit (1205606) writes "Astronomers have figured out how to make the universe’s most powerful magnet. All you need is two massive stars orbiting close to each other so that one swipes gas from the other, causing the thief to spin so quickly that its magnetic field dwarfs that of Earth by 100 trillion-fold. The finding offers fresh insight into how some of the galaxy's smallest but most extraordinary stars arise."

+ - Autodesk Unveils 3d Printer As It Aims To Become Industry's Android

Submitted by Hugh Pickens DOT Com
Hugh Pickens DOT Com (2995471) writes "BBC reports that Autodesk — the leading 3D modelling software-maker — is going into hardware with its own 3D printer and in addition to selling the machine, Autodesk will also allow other manufacturers to make their own versions of the printer or power their own models off its software at no cost. "The printer is a bona fide attempt to prove the interoperability and open source nature of Autodesk's platform," says Pete Basiliere. "And by sharing its design we could see a second wave of small start-ups creating stereolithography machines just as the makers did when the early material extrusion patents expired." Chief executive Carl Bass likened the new printer to Google's first Nexus smartphone, a product meant to inspire other manufacturers to install Android on their handsets rather than become a bestseller itself. In Autodesk's case the idea is to drive the adoption of its new Spark software, a product it likens to being an "operating system for 3D-printing". Although Autodesk is giving away both Spark and the printer's design, the company should still profit because the move would drive demand for the firm's other products. "If 3D printing succeeds we succeed, because the only way you can print is if you have a 3D model, and our customers are the largest makers of 3D models in the world."

Instead of the extrusion technique most commonly used by existing budget printers, Autodesk's printer uses a laser to harden liquid plastic to create the objects delivering smoother, more complex and more detailed objects. "We're making a printer that, rather than just being able to load in proprietary materials, you can load in any material you want. You can formulate your own polymers and experiment with those. That's an important next step because we think material science is a breakthrough that has to happen to make [the industry] go from low-volume 3D-printed stuff to where it really starts changing manufacturing." Bass said, its printer is targeted at more professional users–for creating small objects like medical devices or jewelry–and will likely end up closer to the $5,000 range, though exact pricing has not been set."

All the simple programs have been written.
