Modified radar gun identifies suicide bombers up to ten meters away
William Fox of the Naval Postgraduate School in Monterey and John Vesecky, his colleague at UC Santa Cruz, are working on a modified radar gun that can identify suicide bombs worn under the clothing. To do this, they cataloged the most common arrangements of looped wires used to construct "suicide vests," and developed software that can identify the radar cross-section of each. So far, results have been pretty good: according to New Scientist, "telltale factors in the polarisation of the reflected signals" allowed them to correctly identify volunteers dressed as bombers up to ten meters away, roughly eighty-five percent of the time. Of course, even with a success rate this high, such a system would be prone to kicking up false positives. In order to minimize this, the devices would have to combined with other technologies, such as smart surveillance camera systems and infrared imaging.
Scientists discover planet capable of supporting life, Richard Branson calls dibs on it
A team of planet hunters from UC Santa Cruz (not to be confused with Dog The Bounty Hunter) have found a planet three times the size of our own that might support life. Scientists have been using the HIRES spectrometer on the Keck I Telescope to keep an eye on the Gliese 581 red dwarf star in the constellation Libra for about 11 years now, and among its many virtues have learned that the planet Gliese 581g has the potential for life. Indeed, it is being billed as "the first potentially habitable exoplanet," meaning that it's in "the zone" where it's neither too hot nor too cold for liquid water. Although it's rather Earth-like in some respects, there are some stunning differences: for instance, the planet doesn't spin on its axis, so one side is always dark (and probably 25 degrees below zero) while the other side is probably rather pleasant, or "shirt-sleeve weather," as one of the discoverers, Steven Vogt, put it. Indeed, he goes on to estimate that "chances for life on this planet are 100 percent." Those are pretty good odds! There's no word on when Virgin Galactic will be offering vacation packages to this hit destination, or even when it will be feasible to make the 20 light year voyage.

Ethernet speeds raised to 100 gigabits per second
Our consumer-grade home DSL is starting to look pretty paltry compared to the records that are coming out of research labs these days. While we told you about the latest speed record of 14 terabits per second over fiber in Japan, that really doesn't help use mere mortals who are still using 100Base-T routers in our homes and offices -- even though about a month ago, we spied one of the first gigabit routers on the market, which raised our spirits a bit. Well our hopes have been kicked up a few more notches today, with the news from GigaOm that Infinera, the University of California Santa Cruz, Internet2 and Level3 Communications have just demoed a 100 gigabit per second Ethernet connection over a fiber network between Houston, Texas and Tampa, Florida. Now if only we could get the IEEE bureaucracy and networking manufacturers to move this fast -- we need at least a gigabit per second in our pads, like, last year.
