Rational Egoist writes “Scientists working at the National Institute of Standards and Technology have come up with a novel, easy way to detect life on other planets. Rather than try to measure the composition of atmospheres, they want to look at the chirality of light coming from the planet. From the article: ‘”If the [planet’s] surface had just a collection of random chiral molecules, half would go left, half right,” Germer says. “But life’s self-assembly means they all would go one way. It’s hard to imagine a planet’s surface exhibiting handedness without the presence of self assembly, which is an essential component of life.”‘ And they have already built a working model: ‘Because chiral molecules reflect light in a way that indicates their handedness, the research team built a device to shine light on plant leaves and bacteria, and then detect the polarized reflections from the organisms’ chlorophyll from a short distance away. The device detected chirality from both sources.’ The article abstract is available online.”

Mike writes “It’s official: Yahoo is pulling the plug, and GeoCities is dead. GeoCities had suffered a long and drawn-out battle with its health over the past decade. An antiquated service model and outdated technology are widely blamed for the struggle. An official cause of death, however, has yet to be determined. Awful, eye-punishing graphics, lack of relevancy, and ‘lowest-common-denominator design’ are believed to have contributed to it’s demise. GeoCities was 15 years old.” There is doubtless a lot of funny and informative stuff on there that’s worth saving (not just Jesux, which pudge has now migrated). If some of it belongs to you, perhaps you should move it sometime in the next few months.

CWmike writes “Advanced Micro Devices on Thursday introduced the latest member of its Phenom II X4 family of high-performance quad-core CPUs, which the No. 2 chip maker said it had run as fast as 7 GHz in extreme overclocking tests. Out of the box, the new X4 955 Black Edition, which is aimed at gamers and hobbyists, runs at 3.2 GHz, giving it similar performance to Intel’s fastest desktop chips at lower cost, AMD says. The company was able to more than double the CPU’s speed during its tests using extreme cooling technology that is not safe at home, said Brent Barry, an AMD product manager. The Web site Ripping.org notes that hobbyists with early access to the X4 955 chip have been able to clock it at up to 6.7 GHz. AMD said the chip was safe with fan cooling at up to 3.8 GHz.”

Al writes “Technology Review has a in-depth article about the anonymous networking software Tor and how it is helping dissidents spread information in oppressive regimes such as Syria, Zimbabwe and Mauritania, and opening up the unfiltered web for users in many more countries. In China, for instance, the computers found in some web cafes are configured to use Tor automatically. Interestingly, some police agencies even use the software to hide their activity from suspects. As filtering becomes ever more common in democratic countries such as the US, perhaps Tor (and similar tools such as I2P), will become even more valuable.”

Hugh Pickens writes “The Governator revealed this week that he may appear in the upcoming “Terminator Salvation” but when he said he didn’t want to act, he left many fans scratching their heads. Turns out Schwarzenegger has been secretly working with helmer McG and the effects team to reprise his signature role … without lifting a finger. ‘I made it very clear that I don’t have the time to do the movie,’ says Schwarzenegger. ‘I said that I would be willing to be in the movie if they get the technology together, and so they are working on that right now.’ A body-cast mold of Schwarzenegger, created when he first appeared as the muscle-ripped cyborg, provided the basis for a digital-effects version of his famous character so the figure can appear in “Terminator Salvation” as a living, breathing actor. Warners first screens the movie in early May and opens it May 21. ‘I think it’s cool to continue on with the franchise . . . in case I want to jump over again and get into the acting after I’m through here,’ adds Schwarzenegger.”

Kaliann writes “Toys that respond to brainwaves are the next generation of unique user interfaces. The Washington Post looks at the current market appeal and future uses of technology that can meaningfully respond to the thoughts of a user. Currently the toys have a fairly simple basic idea: the harder you concentrate the more the object moves. A sensor on the forehead picks up brain waves that are associated with concentration, then levitates a ball in response: basic biofeedback. While this may seem to be a rather humble beginning, progress in this field could have astounding consequences in the advancement of technologies devoted to thought-controlled devices. As the author points out, Jedi Beer Pong is within our grasp.”

Hugh Pickens writes “NPR reports that owners of ships that ply the dangerous waters near Somalia are looking at options to repel pirates including slippery foam, lasers, electric fences, water cannons and high-intensity sound — almost anything except guns. One defense is the Force 80 squirt gun with a 3-inch nozzle that can send 1,400 gallons a minute 100 yards in any direction. ‘It is a tremendous force of water that will knock over anything in its path and will also flood a pirate’s ship very quickly,’ says Roger Barrett James of the the Swedish company Unifire. Next is the Mobility Denial System, a slippery nontoxic foam that can be sprayed on just about any surface making it impossible to walk or climb even with the aid of a harness. The idea would be to spray the pirate’s vessel as it approached, or to coat ropes, ladders, steps and the hull of the ship that’s under attack. The Long Range Acoustic Device, or LRAD, a high-powered directional loudspeaker allows a ship to hail an approaching vessel more than a mile away. ‘Knowing that they’ve lost the element of surprise is half the battle,’ says Robert Putnam of American Technology Corp. The LRAD has another feature — a piercing “deterrent tone” that sounds a bit like a smoke detector alarm with enough intensity to cause extreme pain and even permanent hearing loss for anyone directly in the beam that comes from the device. But Capt. John Konrad, who blogs for the Web site Gcaptain.com, says no anti-pirate device is perfect. ‘The best case scenario is that you find these vessels early enough that you can get a Navy ship detached to your location and let them handle the situation.'”

blackbearnh writes “One of the biggest problem that a platoon on the ground in Iraq or Afghanistan faces is that when a new unit cycles in, all the street-sense and experience of the old unit is lost. Knowing where insurgents like to plant IEDs, or even which families have a lot of domestic disputes, can spell the difference between living and dying. In response to this, DARPA created TIGR, the Tactical Ground Reporting System. Developed as much on the ground in active warzones as in a lab, TIGR lets platoons access the latest satellite and drone imagery in an easy-to-use map based interface, as well as recording their experiences in the field and accessing the reports of other troops. In this O’Reilly Radar interview, two of the people responsible for the development of TIGR talk about the intel issues that troops face in hostile territory,the challenges of deploying new technology meant for combat areas, the specific tricks that they had to employ to make TIGR work over less-than-robust military networking, and how TIGR is impacting platoons in their day to day operations”

“Although we usually wait until a feature is fully baked before showing off the technology behind it, we’re just too excited about this new project to keep it to ourselves.” Schnikes that’s fast!
