Submission + - The New Lobotomy

An anonymous reader writes: Popular Science reports on a possible cure for extreme depression: "The most promising new treatment for severe depression isn't a pill. It's a permanent implant that shocks the brain." Currently, fewer than 50 patients have undergone the treatment, but the early results have been astonishingly promising — people experiencing results within hours of the the surgery.

Submission + - Engineer plans to market Robot Baby (cnn.com)

greginnj writes: "David Hanson is a robotics engineer in Texas who has built a prototype robot baby modeled after his own young son Zeno. He currently builds and sells customizable robotic heads; according to TFA, consumer versions of baby Zeno should be available in the next three years for less than $300."
Communications

Submission + - Squirrels use infrared signalling to scare snakes

arneMan writes: A recent article in PNAS reveals a novel mode of communication between ground squirrels and rattlesnakes. Apparantly, squirrels can scare off snakes by employing a technique called "tail flagging" — frenetic back and forth waving of the tail, "harassing" the snake. Using infrared cameras, scientist have discovered that when encountering infrared sensitive rattle snakes, the tail also heats up, putting even more fear into the snake. Experiments using a robotic squirrel (!) confirms this. Interestingly, the squirrel can discriminate between infrared sensitive and non-sensitive snakes, only heating up the tail if it encounters the former kind. Only the abstract is availabe for non-subscribers, but here is a summary of the article along with some nice pics and movies.

Submission + - Diamond synchrotron reads unrolled scrolls

An anonymous reader writes: The hidden content in ancient works could be illuminated by a light source 10 billion times brighter than the Sun. The technique employs Britain's new facility, the Diamond synchrotron, where intense light beams will enable scientists to uncover the text in scrolls and books without having to open — and potentially damage — them. Iron gall ink, which is made from oak apples, has been in use from the 12th Century, but causes parchment to deteriorate rendering precious documents unreadable. Scientists from the University of Cardiff have developed a technique that uses a powerful x-ray source to create a three-dimensional image of an iron-inked document. The team then applies a computer algorithm to separate the image into the different layers of parchment, in effect using the program to unroll the scroll. Professor Tim Wess, who led the research, said: "We've folded up a real piece of parchment and then done a process of x-ray tomography on it. We've been able to recover the structure where we can see the words that are written inside the document." The team now plans to use the Diamond synchrotron's powerful x-ray source to penetrate many layers of parchment.

Submission + - T. rex was relatively slow, lumbering animal (msn.com)

Lucas123 writes: "A new study found that the typical T. rex was a relatively slow animal running at no more than 25mph, 20 miles an hour slower than the 45mph we often seen depicted in movies such as Jurassic Park, and its inertia would have kept it from turning quickly — even slower than a human being. "We now know that a T. rex would have been front heavy, turned slowly and could manage no more than a leisurely jog," said team leader John Hutchinson of the Royal Veterinary College."

Submission + - Sony: Children Should Power Their Own Toys (ecogeek.org)

hankmt writes: "Looks like Sony is developing a line of digital devices including a digital camera, a video recorder and maybe an MP3 player for kids that will be powered by the 'boundless energy of children by having them generate electricity through cranking, rolling, and twirling their gadgets.'"
Operating Systems

Submission + - Learn how Linux manages memory one slab at a time

Anonymous Coward writes: "Good operating system performance depends in part on the operating system's ability to efficiently manage resources. In the old days, heap memory managers were the norm, but performance suffered due to fragmentation and the need for memory reclamation. Today, the Linux kernel uses a method that originated in Solaris but has been used in embedded systems for quite some time, allocating memory as objects based on their size. This article explores the ideas behind the slab allocator and examines its interfaces and their use."

Submission + - Intel Discrete Graphics in 2008? (hothardware.com)

Chandon Seldon writes: According to Hot Hardware, Intel has entered negotiations with graphics card manufacturers to make mid-range discrete graphics cards based on Intel graphics chipsets. It looks like AMD has a deadline on actually providing Open Source 3D drivers (or at least programming documentation) — once Intel starts competing they really don't want to be stuck playing catchup like they are on CPUs.

Submission + - 25 Things You Didn't Know About World of Warcraft (wanderinggoblin.com)

Stinkerbelle writes: "Think you know everything about World of Warcraft? Think again! The guys at WanderingGoblin.com recently attended Blizzard's South Korean gaming conference, and spent every waking moment talking to a rather large variety of developers, execs, employees, and PR people. The result is quite an amusing list of factoids, trivia, insights, and scoop into the world's biggest online game. The tidbits they've uncovered are, obviously, not the kind of thing you'd find in an official press release, and make for an amusing write-up of the game."

bob82 writes: "The MSI GX600 is being dubbed the world's first Turbobook. Why, you might ask, would they call it a Turbobook? Well, what about the neat little overclock button that kicks the CPU speed up a notch when your computer is in AC mode (and by notch we mean 20%) for when you really need your computer working overtime."

eldavojohn writes: "According to Google, Microsoft's server software is at least twice as likely to host viruses or malware. The reason why? "Google reports that IIS is likely used to distribute malware more often than Apache because many IIS installs are on pirated Windows versions which aren't configured to automatically download patches. (Even pirated Windows versions can automatically received security fixes, however.) "Our analysis demonstrates how important it is to keep web servers patched to the latest patch level," Google notes.""
