Understanding How CAPTCHA Is Broken
An anonymous reader writes "Websense Security Labs explains the spammer Anti-CAPTCHA operations and mass-mailing strategies. Apparently spammers are using combination of different tactics — proper email accounts, visual social engineering, and fast-flux — representing a strategy, explains their resident CAPTCHA expert. It is evident that spammers are working towards defeating anti-spam filters with their tactics."
Mars Harder and Colder Than Previously Thought
coondoggie writes "Turns out that the surface of Mars is stiffer and colder than previously thought. New observations from NASA's Mars Reconnaissance Orbiter indicate that any liquid water that might exist below the planet's surface and any possible organisms living in that water would be located deeper than scientists had suspected. NASA made the discovery while using the Shallow Radar (SHARAD) instrument on the Orbiter, which revealed long, continuous layers stretching up to 600 miles or ab...
Firefox 3 RC1 Out Now
Jay writes "Firefox 3 Release Candidate 1 is out now. If yours didn't auto-update, then get it while it's hot! The release came a bit early with Computer World noting: 'As recently as last Saturday, Mozilla's chief engineer said that although the company had locked down RC1's code, it was planning to publicly launch the build in "late May."'" My copy just downloaded — restarting after I save this story. God I hope it's better than the last beta.
Unmanned Aircraft Pose US Airspace Problems
coondoggie writes to tell us that congressional watchdogs have called on Congress to create a body within the FAA to oversee unmanned aircraft development and integration. The group cited the rapidly growing unmanned aircraft community and is worried about the possible repercussions. "The GAO also called on the FAA to work with the Department of Defense, which has extensive unmanned aircraft experience to issue its program plan. In addition, the Department of Homeland Security (DHS) assesses ...
World's Newest, Most Powerful Laser Comes Online
deglr6328 writes "The OMEGA EP laser at the University of Rochester's Laboratory for Laser Energetics was dedicated today at the Robert L. Sproull Center for Ultra High Intensity Laser Research. The new laser, which has been in design since ~2002 will, at 1 kilojoule per 1 picosecond pulse, be the highest energy petawatt scale laser ever created by far. For a fleeting fraction of a second, it will deliver a beam of infrared light at 1054 nm that is more powerful than the total energy consumpt...
The World's Spookiest Weapons
DesScorp writes "Popular Science has a piece on some outrageous ideas for weapons; some came to fruition, and others didn't. And while some of the weapons (atom bombs, chemical weapons, bats with bombs strapped to them that seek out homes and buildings at night) are truly frightening, some of them are also kind of silly, such as the Gay Bomb, and the Frisbee bomb that was labeled the 'Modular Disc-Wing Urban Cruise Munition.'"
NSF Research Reveals Chain Letter Travel Patterns
alphadogg writes to tell us that the NSF is researching chain letters and how they travel. The results aren't quite what one might expect, showing a pattern of more selective and circuitous travel. "One surprising finding was that messages often took meandering routes between people who knew each other, often through as many as 100 intermediaries. Many email users also received copies from multiple social groups. The researchers concluded that because messages come from many directions, there...
US Senate Asks for National Security Letter Explanation
A group of U.S. Senators are asking the FBI to explain a recent controversial National Security Letter sent to the Internet Archive. The Internet Archive was able to defeat the request with help from the EFF and the ACLU this past April. "The Internet Archive's case is only the third known legal challenge to NSLs, despite the fact that the the FBI issues tens of thousands a year -- more than 100,000 such letters were issued in 2004 and 2005 combined. But despite the lack of legal challenges f...
A Baseball Hat That Reads Your Mind
esocid writes to tell us that researchers from Taiwan have created a new baseball cap complete with embedded -bio-signal monitoring system. The purpose was to give a neural interface that could be useful in everyday life. "The cap contains five embedded dry electrodes on the wearer's forehead, and one electrode behind the left ear, that acquire EEG signals. Then, the EEG signals are wirelessly transmitted to a data receiver, where they are processed in real-time by a dual-core processor. The ...
Amputee Sprinter Wins Olympic Appeal to Compete
Dr. Eggman writes "Oscar Pistorius, a 21-year-old South African double-amputee sprinter, has won his appeal filed with the Court of Arbitration for Sport. This overturns a ban imposed by the International Association of Athletics Federations, and allows Mr. Pistorius the chance to compete against other able-bodied athletes for a chance at a place on the South African team for the Beijing Olympics. He currently holds the 400-meter Paralympic world sprinting record, but must improve on his time...
