There are more than a couple of reasons why 3D printing hasn't truly hit critical mass, and the team at M3D thinks it's sidestepped them with The Micro, its $200 - $300 3D printer. The Micro is hitting Kickstarter today with the sole intention of...
That may look like an ordinary Volvo S60, but it's far from it. Inside that handsome but inoffensive Swedish body is the same technology that helped make Formula One cars so fast in the last few years — the hybrid Kinetic Energy Recovery System

Apple has had a mixed relationship in the past with colorful products, but so far the iPad hasn't been one of them. Meanwhile, Nokia has just dropped its first Windows 8.1 tablet, the Lumia 2520, and it's plastic, colorful and relatively well priced. Apple recently brought out a colorful, plastic device of its own, the iPhone 5c, so how would you like a similar tactic with the iPad? How about a plastic, colorful iPad c?
The Lumia 2520 is available for $499 off contract with 4G LTE and 32GB of on-board storage, and the latest Qualcomm Snapdragon 800 chip. Ignoring the Windows 8.1 vs iOS argument, on specs alone the shiny red plastic tablet offers more for the money than the iPad Air. But Nokia has managed to cram an excellent display and all that additional hardware goodness into a colorful, plastic shell, and no-one could ever accuse it of not standing out in a crowd.
So, how about it? Would you go for a plastic clad iPad that came in your favorite color, or are you happy enough with what we're offered at present? As ever, stick a vote up top and your thoughts in the comments below! And for more on the Nokia Lumia 2520, be sure to check out the full review over at Windows Phone Central

Holy wow this is impressive. Artist Anders Ramsell animated Blade Runner by painting 12,597 different water color paintings and stringing them together into beautifully fluid sequences. It's incredible, you feel like you're watching Blade Runner, you get to hear Harrison Ford and follow the story but you're seeing it like never before—in moving art.

MADISON Even as the rate of diagnosis has reached 11 percent among American children aged 4 to 17, neuroscientists are still trying to understand attention deficit hyperactivity disorder (ADHD). One classic symptom is impulsivity the tendency to act before thinking.
Scientifically, impulsivity can appear as a choice for a small but immediate reward over a larger one that requires some delay. Choosing between present and future rewards is a fundamental need in schooling, says Luis Populin, associate professor of neuroscience at University of Wisconsin-Madison. "If you say to an impulsive child, 'Do your homework so you will get a good grade at the end of the quarter,' that has less appeal than 'Let's play baseball this afternoon instead of studying chemistry.'"
To study impulsive behavior, Populin and graduate student Abigail Zdrale Rajala selected two rhesus macaque monkeys with opposite behaviors. One was extremely calm, while the other was nervous, fidgety and impulsive. The monkeys were trained to stare at a dot on a screen and, when it went dark, to choose between two pictures placed to the side. Their choice of picture determined whether they got a small but immediate sip of water, or a larger sip, after a delay ranging up to 16 seconds.
As expected, the calm monkey, but not the impulsive one, quickly figured out that waiting would bring the sweeter result.
This willingness to take a smaller reward right away rather than a larger, delayed reward, called "temporal discounting," is a common feature of "combined type" ADHD, which specifically lists impulsivity among its diagnostic criteria, Populin says.
When the monkeys were given a dose of methylphenidate, the active ingredient of the common ADHD drug Ritalin, they chose the delayed reward more frequently. The impulsive monkey actually showed the same preference for delayed rewards as the unmedicated, calm monkey. However, identifiable differences in their performance mean that methylphenidate improved the condition, but did not eliminate it.
"There is no perfect animal model of ADHD," says Rajala, "but many studies are performed on rodents; this one was done in a non-human primate, which is much closer to humans." The Society for Neuroscience adjudged the paper valuable enough to support Rajala's travel to the conference in San Diego.
Methylphenidate changes the elimination of dopamine, a "reward" neurotransmitter that is elevated by drugs like cocaine and amphetamine. The result is that more dopamine remains in the brain, which is the most likely explanation for the altered reward processing in the medicated monkeys.
Some scientists have thought that temporal discounting in ADHD may result from cognitive processing, which relies on the highly evolved frontal cortex in the brain. The new results support an alternative, but less common, hypothesis: that temporal discounting is linked to the reward-processing mechanism, which is governed by more primitive parts of the brain.
By teasing apart one characteristic of ADHD, the study could help refine drug or behavioral treatments of a disability that has grown 16 percent more common just since 2007, Populin says.

Perhaps Google realized that deactivating Glass if Explorers sell or give it away is a tad draconian and as a result, has recently changed its policy. While it's still against Mountain View's terms of service to sell off its futuristic eyewear, the amended Glass FAQ reveals that the company doesn't plan on "disabling any Explorer's device" anymore. However, since owners aren't explicitly allowed to sell, you likely won't find one listed on eBay, and chances are any attempt will be pulled down in a jiffy. Of course, if you can't find a second-hand unit and don't have a Glass-owning pal, guess what? You can always purchase an invite on Craigslist -- just keep your scam radar set to high.
