Your car might see a deadly crash coming even if you don't, the government says, indicating it will require automakers to equip new vehicles with technology that lets cars warn each other if they're plunging toward peril. The action, still some years off, has "game-changing potential" to cut collisions, deaths and injuries, federal transportation officials said at a news conference Monday.
Apple reshaped technology and society when Steve Jobs unveiled the iPhone seven years ago. Now, the trend-setting company is losing ground to rivals that offer what Apple has stubbornly refused to make: smartphones with lower prices and larger screens than the iPhone. The void in Apple's lineup is a major reason why the company's quarterly revenue may be about to fall for the first time in more than a decade.
A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100% accuracy over a much wider range than current systems.

According to a report from The New York Times, the National Security Agency has implanted software in nearly 100,000 computers around the world that allows the U.S. to conduct surveillance on those machines. The technology, which is not used in the U.S., relies on radio waves that can be transmitted from tiny circuit boards and USB cards inserted covertly into the computers.
Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, Duke Univ. researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.
The completion of the 30-day Lunar Laser Communication Demonstration (LLCD) mission has helped confirm laser communication capabilities from a distance of almost 250,000 miles. In addition to demonstrating record-breaking data download and upload speeds to the moon at 622 and 20 Mbps, respectively, LLCD also showed that it could operate as well as any NASA radio system.
Researchers at the Univ. of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, covering 27,000 square miles and could figure significantly in understanding the contribution of snowmelt and ice melt to rising sea levels.
After successfully text messaging “O Canada” using evaporated vodka, two researchers in Canada and their UK-based counterpart say their simple system can be used where conventional wireless technology fails. The chemical signal, using the alcohol found in vodka, was sent 4 m across the lab with the aid of a tabletop fan.
A new device transforms almost any bicycle into an electric-hybrid vehicle using an app on a smartphone. The device, called the Copenhagen Wheel, is is equipped with wireless connectivity to track travel and installed as part of a rear hub of a bike wheel. Packed with a proprietary computer, batteries, and sensors that monitor how hard a rider is pedaling, it activates an onboard motor whenever support is needed.
To support research efforts in Antarctica, a Penn State Univ. geoscience professor has developed a new type of seismometer, which measures the way seismic waves move through the ice. The “geoPebbles” act as laptops without screens. Equipped with WiFi, they don’t have to be plugged in and charge wirelessly, letting scientists collect data without exposure to the cold.
Although high-definition displays on smartphones have gotten bigger and their cameras have gotten better, the pace of gee-whiz innovation has dawdled. Smartphone and software makers are working on ways to snap out of this technological lull, although it probably will be at least another year or two before breakthroughs revolutionize the design and function of mobile computing devices.
Gaming could become much more realistic with new technology developed at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) that permits highly accurate, 3-D motion tracking. The new system, dubbed “WiTrack”, uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 cm, about the width of an adult hand.
