Cutting Edge

What could make an awesome $35 bare-bones Linux system even more awesome? Sending it on an excellent, solar-powered trans-Atlantic journey, of course!

The FishPi project is one man's dream to use the Raspberry Pi microsystem to pilot a tiny craft across the ocean.

The idea is not just to redefine the term "budget cruise," but to prove that the inexpensive system can successfully guide and control a trans-oceanic vessel. The visionary behind the project, Greg Holloway, is currently working on a proof-of-concept vehicle for the project -- dubbed Fish Pi. Here's how he describes the plan on the project site:

I can't wait for the era of self-driving cars. I can't believe it's 2012 and we still have to turn a steering wheel and push pedals to get around while we could be doing better things like sleeping, reading, or actually watching the scenery roll by instead of the road.

The Japanese government has started talks on the goal of getting self-driving cars on public roads by the early 2020s.

The Ministry of Land, Infrastructure, Transport, and Tourism has said it's the first in the world to seriously consider robot cars for the masses, according to Nikkei Automotive News.

A United Launch Alliance Delta 4 rocket, the most powerful in the postshuttle U.S. inventory, boosted a top-secret National Reconnaissance Office spy satellite into space early Friday, after a spectacular morning launch from Cape Canaveral.

Running three hours late because of technical snags, the 232-foot-tall rocket, made up of three liquid-fueled common core boosters and a powerful upper stage, roared to life at 9:15 a.m. EDT (GMT-4) and quickly climbed away from launch complex 37 at the Cape Canaveral Air Force Station.

Generating nearly two-and-a-half million pounds of thrust from three upgraded Pratt and Whitney Rocketdyne RS-68A more

China's Shenzhou 9 spacecraft, carrying two men and the first Chinese woman to fly in space, returned to Earth on Friday after an ambitious flight to a prototype space station module, plunging back into the atmosphere and descending under a large parachute to a jarring touchdown in Inner Mongolia.

The re-entry was carried live on Chinese television, with commentary, shots of the crew in the cramped decent module and views of the spacecraft's fiery re-entry plume as it streaked across the sky on a steep northeasterly descent toward the landing zone.

The 12-day 15-hour mission ended with a more

Sergey Brin stormed on the stage in his Google Glasses like Iron Man Tony Stark, prepared to give the crowd of 5,500 developers what he called an "awesome" display of technology and daredevil live action.

He gave the play-by-play as a troop of skydivers, bikers, and rope rappellers converged on the Moscone convention center, in a scene that could have been the opening sequence of a "Mission: Impossible" movie (if it wasn't part of Brin's Google I/O Glass demo). 

The skydivers made jumping out of an airship look easy. But before they could do it, more

Brainiacs at Rice University today debuted a spray-on lithium ion battery that they say could be applied to nearly any surface. You read that right -- a paintable battery.

The paint contains layers, each representing a necessary component of a conventional battery -- current collectors made in part from purified single-wall carbon nanotubes, a cathode, an anode, and a polymer separator -- as described in a report published today in Nature authored by Rice graduate student Neelam Singh and her team. Spraying the painted battery is a multilayer process, but when you're done, you have a covered surface that stores energy and discharges it when needed -- that is, a battery.

Earlier this spring, the U.S. Army revealed the existence of a project underway to build a device that could shoot lightning bolts down laser beams to take out a target. Now the military's boffins report success in their first tests.

The technology -- known as laser-induced plasma channel -- is designed to seek out targets that conduct electricity better than the air or ground that surrounds them.

Although scientists and engineers working on the weapon's development expressed confidence in the physics behind their work, George Fischer, who is the lead scientist on the project, nonetheless cautioned about the technical challenges still ahead.

Two separate studies published this month indicate that it may be possible to use brain imaging techniques to reliably detect autism in children as young as 6 months of age.

In the first study, published in the American Journal of Psychiatry, researchers from across North America working on the larger and ongoing Infant Brain Imaging Study used a type of MRI called diffusion tensor imaging to study 92 6-month-olds deemed high risk because their older siblings had been diagnosed with autism.

What they found is that the organization of white matter in the brain plays a key role. Specifically, they more

In case you were in any doubt about the superiority of robots to humans, Japanese researchers have unleashed a machine that's unbeatable at that timeless human test of wills, rock, paper, scissors.

The boffins at the Ishikawa Oku Lab in the University of Tokyo call it a "human-machine cooperation system," but this robot hand doesn't seem interested in cooperating at all.

It's only interested in winning, and it does that by cheating, in a sense.
