GPS may now reside in everything from our cars to our smart phones, but it once all began as a military application. So it's perhaps ironic, if not entirely shocking, that the head of the U.S. Air Force said today that the military needs to wean itself off dependence on a GPS network vulnerable to jamming and satellite-killing vehicles. DOD Buzz reports that officials have confirmed that GPS has been "jammed or interfered with recently."
Humans built electrical barriers and dumped poison in the Illinois waterways, but an alien species still managed to leave a disturbing presence in the waters of Lake Michigan near Chicago. Fresh lake samples taken in December revealed the DNA of aggressive Asian carp, according to the Journal Sentinel. That news surfaced even as the U.S. Supreme Court announced yesterday that it had turned down a plea from Great Lakes states to force the U.S. Army Corps of Engineers to shut lakeside navigation locks against the intruders.
Silver miners first discovered Mexico's surreal Cave of Crystals almost a decade ago. The BBC recently took a rare tour of the underground cavern that contains the world's largest naturally grown crystals, where some selenite structures reach almost 33 feet in length.
See those little dots climbing the crystals that look like ants? Those are people.
Stopping a speeding car without killing its driver and passengers with traditional means--bullets--can prove tricky, even if skilled snipers can put a disabling shot in a car's engine block. But a Canadian company could soon demo an electromagnetic pulse (EMP) cannon capable of effectively scrambling a car's chips and other electronics, according to Flight International. The U.S. Marines have lined up as possible, if skeptical, customers.
A camera aboard NASA's Mars Reconnaissance Orbiter (MRO) has taken nearly 13,000 observations of the red planet, but might only now begin to live up to its nickname of "the people's camera." The U.S. space agency has announced a new chance for you, dear reader, to suggest where that spacecraft should point its camera next.
Netizens can see both existing images and suggested targets on a new public suggestion website. They may then use a simple rectangle to designate their location of choice for MRO's HiRISE camera.
Pull those Benjamins out from under the mattress and get ready to bid on your very own six-axis robot arm. A Chrysler plant near the University of Delaware has been liquidated and is up for auction, including about 200 down-to-Earth, maker-fearing robots.
Future humans won't have to wait to travel to Pandora for the chance to mine unobtanium, because Neptune and Uranus may have diamond icebergs floating atop liquid diamond seas closer to home. The surprise finding comes from the first detailed measurements of the melting point of diamond, Discovery News reports.
A Chinese cyber-assault on Google and more than 30 other U.S. companies was the most sophisticated online attack ever seen outside of the defense industry, according to experts from anti-virus firm McAfee interviewed by Wired. Google announced on Tuesday that it would no longer censor information on its search portal per Chinese government rules, and may stop doing business in China entirely.
NASA's original concept for a balloon scout on Saturn's moon Titan called for using waste heat from a radioisotope power system. But such systems come with the major downside of not providing enough heat for sudden course changes -- a problem that one company plans to solve by using hot air balloon technology, The Register reports.
Judgment Day has come for the machines, or at least two robotic warriors once slated for the U.S. military's arsenal. The budget cut casualties include a mine-sniffing, six-wheeled transport called the MULE, and an autonomous helicopter called the Fire Scout, according to The Hill.
