This light bulb costs less than $1 and fits in your wallet

With summer coming, chances are that you'll be spending a little more time outside at night than usual. Which means you'll need artificial sources of illumination.

I just came across one such glowing goodie that I needed to share with Crave readers.

It's called the "New LED Design Renovation Credit Card Size Ultra-slim Fold-up LED Pocket Wallet/Purse Lamp/Light," which is truly an unfortunate name for something so cool. I think "Pocket Bulb" or something like that would have done much better.

Bus powered by cow poop beats speed record

The land speed record for a regular bus has been shat on. "Bus Hound," powered by biomethane derived from cow manure, clocked 76.785mph in speed trials in England.

Operated by Reading Buses, the vehicle was painted black and white in honor of the Frisian cows whose excrement powers its mighty engines. It was designed to advance the "power and credibility of buses fuelled by cow poo," reports the BBC.

In the future, a virtual heart may test your medical device for you

“CyberHeart” sounds more like something we’d come across in a Terminator movie, but the new virtual heart platform, led by computer scientists at Stony Brook University, is very much tooled toward humans. CyberHearts will specifically be used to test and validate new medical devices early on during their design phase. By detecting flaws in such devices before animal and human trials begin, CyberHeart, researchers hope, will speed the development process along, while helping to prevent the rollout of products with dangerous and costly bugs.

The brain's unique reaction to words could sign people into devices

posted by Larra Morris

Blair Armstrong and his team of researchers from the Basque Center on Cognition, Brain, and Language in Spain observed the brain signals of 45 subjects while they read a list of 45 acronyms, such as FBI and DVD. According to New Scientist, they found that the volunteers' brains reacted differently to each one, enough for the system to pinpoint their identities with 94 percent accuracy.

Brain signals are typically hard to analyze, so Armstrong's team decided to focus on the part of the brain associated with reading and recognizing words. That part's in charge of recognizing word definitions, which can have subtle differences between people. It can't replace fingerprint scanners just yet, since you still need to be attached to electrodes for the method to work. But Armstrong believes that the technique could be refined further and developed into a viable alternative to fingerprints.

Juvenile plasticity returned to adult mice brains

posted by Larra Morris

By enabling the rigid brains of adult mice to return to the high levels of plasticity found in juvenile brains, scientists are opening new pathways to the treatment of brain injuries such as stroke. Back in 2013, researchers from Yale University reported the discovery of a molecular switch that achieved this result, and now scientists at the University of California, Irvine, have managed to make an old brain young again using a different approach.

The UC Irvine technique involved transplanting a type of embryonic neuron into the brains of adult mice. After transplantation, these neurons expressed GABA (gamma-Aminobutyric acid), a chief inhibitory neurotransmitter in the mammalian central nervous system that aids in motor control, vision and numerous other cortical functions.

Hydrogen-powered drone will fly for hours at a time

posted by Larra Morris

Even the nicer drones you can buy typically last for just minutes in the air, which isn't much help if you're delivering packages or shooting movies. Horizon Unmanned Systems (HUS) thinks it has a solution, however: hydrogen power. Its recently unveiled Hycopter drone runs on a lightweight hydrogen fuel cell that should deliver up to 4 hours of flight time unloaded, and 2.5 hours when it's carrying 2.2 pounds of cargo. That still may not sound like much, but it makes long-distance flights practical -- it's the difference between flying across the city and staying within the neighborhood. HUS won't even fly the Hycopter's prototype until later this year, but patience could well pay off if you're tired of piloting robotic aircraft in half-hour bursts.

Glowing paper could pave the way for bendy devices

posted by Christy Wilding

With the release of Apple Watch and Google Glass, personal electronics are breaking out from our pockets. But even these newest iterations are rigid; despite years of buzz about foldable electronics, you still can’t read a book on your Kindle then fold it up like a newspaper. Now a team of Chinese researchers has developed a glowing, flexible paper designed to bring foldable electronics closer to reality.
