Wi-fi on rays of infrared light: 100 times faster at 40 gigabits per second, and never overloaded  

Researchers at Eindhoven University of Technology have come up with a solution to slow wifi. Use a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light. This was the subject for which TU/e researcher Joanne Oh received her PhD degree with the 'cum laude' distinction last week.The system conceived in Eindhoven is simple and, in principle, cheap to set up. The...

Navy focused on UAV just for refueling for faster development and deployment  

Currently the US Navy refuels its carrier aircraft with its Super Hornet fleet. The tanking mission accounts from anywhere from 25 to 30 percent of Super Hornet sorties, further exacerbating the ongoing tactical aviation shortfalls in the service.That demand - in part - is pushing the Navy to get a tanking UAV into service as soon as possible rather than creating a more multi-mission platform.The Navy's latest revision to the requirements seem to push all the competitors to a wing-body-tai...

Army testing 100 mph tracked ATV  

The 750-horsepower, optionally manned EV2 is capable of reaching speeds of almost 100 miles per hour and costs roughly $250,000.At 9,000 pounds, the Ripsaw is closer in size to the Humvee than a tank. For example, the Army's M1A2 Abrams main battle tank tips the scales at more than 70 tons. Indeed, the Ripsaw isn't even in the same weight class as an M1126 Stryker Combat Vehicle or M2/M3 Bradley Infantry Fighting Vehicle.Also, it doesn't carry the same firepower. The Ripsaw is designed to ...

Under the dead sea, warnings of dire drought  

Nearly 1,000 feet below the bed of the Dead Sea, scientists have found evidence that during past warm periods, the Mideast has suffered drought on scales never recorded by humans -- a possible warning for current times. Thick layers of crystalline salt show that rainfall plummeted to as little as a fifth of modern levels some 120,000 years ago, and again about 10,000 years ago.

New cell membrane fusion model challenges dogma  

Membrane fusion lies at the heart of many cell functions—from the secretion of antibodies to the release of neurotransmitters. For more than two decades, one view of the process by which membrane fusion occurs has been accepted as dogma; now recent studies indicate that fusion is more complex. These discoveries are being regarded by at least one leading cell biologist as "textbook changing" and could alter how we develop drugs that affect membrane fusion activities.
