Chevrolet is offering a sizable price incentive in the face of price slashing in the electric car market.

The 2013 Volt now comes with a $4,000 cash-back incentive and the 2012 model ups that to $5,000, according to Michelle Malcho, a Chevrolet spokeswoman.

That's the largest Volt cash incentive that Chevy has offered to date, Malcho said.

Alternatively, a Volt can now be leased for $269 a month for 36 months with a $2,399 down payment.

The Volt is a plug-in hybrid (GM refers to it as an extended-range electric vehicle or E-REV) with a range … Read more

Ladies and gentlemen, may I now present your deep thought of the day: People who play video games are better at playing video games than people who don't play video games.

OK, new findings out of Duke may be a bit more complex than that, but there's not much of a spoiler alert to this one. Hours spent at a gaming console seem to translate directly to a test, taken at a computer, of how the brain tracks visual stimuli, according to a new study at the Duke School of Medicine.… Read more

The Large Hadron Collider is a monumentally awesome machine, and has given us tentative confirmation of the existence of the Higgs boson, the so-called "God particle." Now scientists hope to follow that with a new accelerator that could explain what makes up 95 percent of the universe.

At three ceremonies around the world Wednesday, researchers hailed blueprints for the International Linear Collider (ILC), a 19-mile-long smasher that might help solve the riddle of dark matter and dark energy, unseen forces with major gravitational effects. … Read more

Pigs may not be flying yet, but a bicycle just recently took to the air in a successful test flight. The flying electric bike is the creation of several Czech companies that have been developing a prototype. The proof-of-concept bicycle looks a bit like a regular bike crossed with a giant RC quadcopter.

The unusual vehicle demonstrated its chops with a flight that lasted a few minutes, carrying a dummy onboard. It was radio-controlled from the ground. The 220-pound bike got off the ground thanks to six battery-powered propellers. This is enough to spark dreams of peddling down the road and then suddenly taking off to fly over obstacles or impress strangers.… Read more

Drawing from engineering ideas that are revamping personal computers, IBM and two Swiss universities are using flash memory to improve performance of a supercomputer designed to simulate an actual mouse brain.

But there's a lot more flash memory than you'll find in the latest laptop.

A PC's solid-state drive may come with something like 128GB to 512GB of flash memory. The mouse-brain project's specially upgraded version of a Blue Gene/Q supercomputer has 250 to 1,000 times as much flash memory -- 128 terabytes.

The supercomputer project, in conjunction with the Ecole Polytechnique Federale de … Read more

When scientists at the University of Washington recently drilled into the skulls of seven people with severe epilepsy and placed thin sheets of electrodes directly onto their brains, they were surprised by the brain activity they observed.

While physicians were studying neuro activity to investigate seizure signals, a separate team of bioengineers was simultaneously on the lookout for exactly how the brains of the seven volunteers behaved as they learned to move a cursor using their thoughts alone. It turns out that, in as few as 10 minutes, activity went from being centered on the prefrontal cortex, which is associated with learning new skills, to areas seen during more automatic functions, such as waving one's hand or kicking a ball.

In other words, in just a matter of minutes these brains behaved as if they had already mastered these Jedi mind tricks.… Read more

With its six Thunderbolt ports and a "unified thermal core," Apple's new Mac Pro doesn't just sound like a futuristic piece of alien machinery, it also looks like something out of science fiction.

Far from the boxy designs of early personal computers, the new Mac Pro is compact, sleek, and nearly edgeless. The resemblance of the Mac Pro, which is aimed squarely at creative pros, to a tiny nuclear reactor is in part due to that heat sucking "thermal core" design. Heat generated from the Intel Xeon CPU and new solid-state drive (SSD) storage dissipates out through the core as the hot air rises -- a change from the typical front-to-back system of air flow in most consumer desktops.… Read more

MONTREAL -- Guitar-strumming astronaut Chris Hadfield is hanging up his spacesuit and quitting the astronaut biz, with plans to pursue "private interests." Does that mean a Leonard Nimoy-style album?

Heralded as the most popular spaceman since Neil Armstrong, the social-media phenom announced his retirement Monday at Canadian Space Agency headquarters outside Montreal, his first Canadian appearance since returning to Earth in May after five months on the ISS.

"I've decided to retire from government service after 35 years of serving our country," Hadfield, 53, told a press conference, adding that he's making good on a promise he made to his wife 30 years ago. … Read more

Nowadays breathalyzers are being used to detect far more than just how much alcohol one has imbibed. Researchers in Sweden are working on one that can spot marijuana and cocaine. Scientists in Germany are exploring one that can sniff out heart failure. And researchers in the U.S. are hard at work on one that can detect diseases such as diabetes.

And now, a group of chemists at the University of Pittsburgh is unveiling new sensor technology that could lead to a breathalyzer for not just the detection of diabetes, but the ongoing monitoring of it as well.… Read more
