Nanocar Wins Top Science Award

Slashdot - December 22, 2008 - 3:31pm
Lucas123 writes "A researcher who built a car slightly larger than a strand of DNA won the Foresight Institute Feynman Prize for experimental nanotechnology. James Tour, a professor of chemistry at Rice Univ. built a car only 4 nanometers in width in order to demonstrate that nanovehicles could be controlled enough to deliver payloads to build larger objects, such as memory chips and, someday, even buildings, like a self-assembling machine. Tour and a team of postgraduate and postdoctoral researchers constructed a car with chassis, working suspension, wheels and a motor. 'You shine light on it and the motor spins in one direction and pushes the car like a paddle wheel on the surface,' Tour said. The team also built a truck that can carry a payload."

Zoe's Tale

Slashdot - December 22, 2008 - 2:26pm
stoolpigeon writes "John Scalzi, the author of Hugo Award-nominated science fiction novel Old Man's War, has built what started as a story serialized in his blog into a series of full novels and short stories. The latest installment in the OMW universe, Zoe's Tale, is quite a departure from the previous three books. It is the first of Scalzi's sci-fi novels written intentionally as young adult fiction. In a move that I am sure will continue to fuel Scalzi/Heinlein comparisons, Zoe is a precocious young woman thrust into a world of adventure and danger. In just three years Scalzi has built an impressive resume as an author of fiction, and Zoe's Tale will be no small part of what looks to be an influential and outstanding career." Keep reading for the rest of JR's review.

Security Flaws In Aussie Net Filter Exposed

Slashdot - December 22, 2008 - 1:19pm
Faldo writes "There's a three-part interview with a computer security expert on BanThisURL that goes into the flaws in the Aussie net filtering scheme. In addition to SSH tunnels and proxies, more worrying problems like trojaning the boxes to set up man in the middle attacks (which the interviewee has done in his lab), cross site scripting and the Australian blacklist leaking are all discussed. Worrying and relevant, especially since Thailand's blacklist has just been leaked."

NSA Patents a Way To Spot Network Snoops

Slashdot - December 22, 2008 - 12:15pm
narramissic writes "The National Security Agency has patented a technique for figuring out whether someone is messing with your network by measuring the amount of time it takes to send different types of data and sounding an alert if something takes too long. 'The neat thing about this particular patent is that they look at the differences between the network layers,' said Tadayoshi Kohno, an assistant professor of computer science at the University of Washington. But IOActive security researcher Dan Kaminsky wasn't so impressed: 'Think of it as — if your network gets a little slower, maybe a bad guy has physically inserted a device that is intercepting and retransmitting packets. Sure, that's possible. Or perhaps you're routing through a slower path for one of a billion reasons.'"

VirtualBox 2.1 Supports 64-Bit VM In 32-Bit Host

Slashdot - December 22, 2008 - 11:15am
Stephen Birch writes "Following closely behind the mid-November 2.06 release of VirtualBox, Sun Microsystems has released version 2.1. This has a number of new features, but one of the most interesting is the ability to run a 64-bit VM inside a 32-bit host. Another useful feature is integrated host-based networking; no more fiddling around with network bridges. Sun is really giving VMWare a run for their money."
