Beer and Urine Make 'NoPoPo' Batteries Last 10 Years



Leave it to our clever, if bizarre, Japanese friends to come up with the NoPoPo battery.

According to Unplggd, the battery gets power when one of several fluids mixes together with its magnesium and carbon components. Among those fluids are beer, saliva and -- that's right -- urine.

Apparently, those unlikely charging agents help the batteries to live for as long as ten years. And the bizarre charging method is much simpler and more sanitary than you'd guess. All you need is a cup, the batteries and the included eyedropper. You can, we're sure, figure out where to go from there.

Even if these AAA and AA batteries wind up being less than satisfactory, the novelty itself is well worth the $15. [From: Unplggd]

Weird Experiment Transposes Your 'Body' to Mannequins, Other Folks


A research team at the Karolinska Institute in Sweden has successfully engineered an experiment in which test subjects perceive themselves as occupying bodies other than their own, USA Today tells us.

The study was designed to research technology potentially useful for robotics and the treatment of sensory disorders. Head researcher Henrik Ehrsson told USA Today, "The participants has [sic] a sensory experience of having a new body. They of course realize that it is an illusion, but they can't think it away," he told Science Fair.

With the aid of cameras, and a mechanism that touches the subject's skin and that of the second body simultaneously, the typical test subject -- over the course of the experiments -- perceived himself as being face-to-face with himself transposed into another person's body, as well as a mannequin. The visual-sensory experiment actually had test subjects "shaking their own hands."

While the success of this experiment could be a boon to disabled folks interested in robotic appendages, we suspect it will be some time before science is able to engineer fully functional, sensitive prosthetics. Let alone prosthetics that allow full-fledged bumping and grinding. [From: Science Fair]

Woman Uses Internet to Fund Boob Job




In yet another sign that things are super weird and only getting weirder by the moment, a Canadian woman named Karla-Rae Morris is getting an $8,000 "breast enhancement surgery" for free. All thanks to some supportive (male) friends she made on a very, very strange Web site.

For those unfamiliar with the world of underground breast surgery, here's how it works: MyFreeImplants.com is a California-based site that allows men to invest in breast augmentation surgery for women with small hooters, who otherwise wouldn't be able to afford it. In exchange for their donations, the women chat online with the men and send them photos and videos of themselves, presumably showing off their new wares.

With her $8,000 in donations, the 5'6", 98-pound Morris plans to undergo surgery this spring to expand from a 32AA to 34C cup.

"I'm going to be really super happy," she told Sun Media. "I always felt like less of a woman and more like a little girl. It's going to make me more confident wearing a swimsuit. And I won't have to buy padded bras anymore."

In other news, people are really super hungry in Africa.

When Exposed to Sunlight, These Clothes Clean Themselves

Could this mean the end of laundry day? Textile scientists in Australia and Hong Kong have developed a special coating for fabrics made of titanium dioxide nanoparticles that actually cause the fabric to self-clean when exposed to sunlight.

Besides the obvious benefit of less time spent doing laundry, the new fabric could also mean less water used to wash clothes and less detergent being washed down drains -- both of which are good for the environment.

Wine stains diminished during the course of a day.When hit by direct sunlight, the nanoparticles -- specifically Keratins, a class of biologically fibrous proteins -- begin to interact with oxygen in the air, breaking down stains and dirt. According to a report on the scientists' findings in the science journal Chemistry of Materials, red-wine stains on pieces of wool started to fade within a few minutes of exposure to light and had all but vanished within a day (see the time-elapsed test here).

Supposedly, the nanoparticle coating does not affect the feel of treated clothing, but it may make the clothing less durable over time. It could take about five years to refine the technology to make it ready for wide distribution and use.

Note: This does not mean you can stop bathing -- an important caveat, especially for the Switched.com interns.

Motorized 'iShoes' to Get Around Town




Meant, presumably, for rich high-school nerds with a hankering for more wedgies, the iShoes make the Segway look cool as ice. Essentially motorized shoes, the iShoes came from the mind of Ilya Kaganovich who, "on a trip to New York, thought of a new way to get around town: motorized shoes," according to the iShoes site." Luckily, Kaganovich's brother, Boris, is an aerospace engineering student, and was able to help develop prototypes for the iShoes, which are now, believe it or not, a reality.

So here we are: The iShoes cost 600 bones and wedgies are up 800%.

Nobody wins here, people.

New Remote-Control Vasectomies Require No Surgery

http://www.mhhe.com/socscience/sex/common/ibank/ibank/0124a.jpg
Might want to sit down and cross the legs for this one, fellas.

A new vasectomy procedure has been developed by a team of researchers from Australia's University of Adelaide. Essentially, it consists of a silicone polymer valve that fits snugly inside the vas deferens, thereby blocking the passage of sperm. The valve is inserted through a hypodermic needle, so there's no need for surgery.

The upside is that there's no surgery, and that the procedure is reversible: The doctor can use radio-wave frequency technology to "open" the valve back up, thus letting you commence baby-making.

"It will be like turning a TV on and off with a remote control," team founder Derek Abbott told New Scientist, "except that the remote will probably be locked away in your local doctor's office to safeguard against accidental pregnancy or potential misuse of the device."

Japanese Robots to Monitor Pollen Levels



Allergies suck -- so the always-resourceful Japanese have decided to sick robots on the problem. Tokyo-based weather forecasting company Weathernews, Inc. is apparently getting ready to install roughly 200 spherical robots across the country to monitor the pollen in the air. The shells of these bots are made of styrofoam, and a monitor inside does the dirty work. The eyes indicate the corresponding levels of pollen in white, blue, green, red and purple colors.

Two hundred hay fever-sufferers around the country will also send minute-by-minute reports via the Internet to Weathernews HQ, all of which will eventually add up to its pollen map for the season.

Robots and humans: working together for a less sneezy planet.

Biometric Dress Changes Color According to Wearer's Mood

Biometric Dress

Check this out: A new prototype dress may one day help dense men or women clue in on their partner's emotional condition. The Daily Mail reports that the Bubelle Dress, designed by scientists at the Dutch electronics company Philips, changes colors depending on the wearer's mood. The dress's development was prompted by a research venture dubbed the SKIN Probe Project, which imagines daily living in the year 2020.

The garment has two connected layers, an inner layer equipped with biometric sensors that pick up physical information correlating to certain emotions, and an outer layer that casts different colors and patterns according to the information gathered. Sweat and temperature levels, the makers say, are key determinants in identifying a person's emotional condition.

The garb is the latest "practical" application in the burgeoning biometric field. While it certainly is the most fashionable development to date, biometrics has been around for a while now, but has traditionally been used on security apparatus like locks and safes. Unfortunately, consumers intrigued by the prospect of such an outfit in their wardrobe will be disappointed to learn that the Bubelle Dress is not currently being produced for the public. On the plus side, this means that Cro Magnon males won't be able to masquerade as Dr. Phil anytime soon.

Nintendo Wii Adopted By Physical Therapists for Patients

Wii Adopted by Physical Therapists

Despite all the stories that claim video games are corrupting our children, plenty of good news regarding video games is also surfacing lately, much of due to Nintendo's charge to expand its market to non gamers. This was spurred on by the success of games like 'Brain Age' among senior citizens, and now the Wii is finding even more success in strange places, like physical therapy offices.

Some therapists are now using the device as a fun prescription, a means to force patients to focus on things like balance and coordination and do so in a confined space. The bowling game in 'Wii Sports,' for example, requires good timing and some reasonably precise movements, and, best of all, can be played without swinging a real bowling ball around.

The Wii Balance Board, coming to the U.S. sometime next year, should make the console even more attractive, allowing the Wii to chart gamers' balance as they perform simple calisthenics, simulate ski jumps, and play silly games that involve leaning.

Now if only if were actually possible to buy one of the things before Christmas.

Man Caught Speeding -- In a Wheelchair




With his mind apparently grasping onto distant memories of cruising down the autobahn in his black Audi A4, a German man was stopped yesterday by police, after they caught him doing 40 mph down a high street in Geseke, Germany -- in his electric wheelchair.

The 54 year-old Guenther Eichmann was apparently a former engineer, and had modded his wheelchair's engine to burn rubber. Doing 40 in a 20 zone, he was actually going twice the speed limit, which we'd translate into kilometers-per-hour for you, were it not for the fact that our collective head would explode.

Eichmann's "vehicle" was confiscated by the cops (kinda harsh, right?), and he was slapped with a £300 fine, or roughly nine billion US dollars.

Monkeys Control Robotic Arms Via Internet



Curious George prefers eating bananas, but playing with robots will do to pass the time. A team of scientists at Duke University took the world by surprise in 2003 when it successfully used monkeys to control robotic arms with only their brains. Don't be surprised, but the Duke team just one-upped itself.

Implanting electrodes into the monkeys' brains, the researchers were able to train the primates to move robotic legs in this iteration of their experiments. Nothing special there, right? Well, the new wrinkle that they presented at this year's Neuroscience Conference was the monkeys' ability to movethe robotic legs from thousands of miles away, with the primates and robotic limbs linked only by the Internet! While the monkeys were at the conference in San Diego, they moved the legs, which happened to across the Pacific at the Advanced Telecommunications Research Institute International in Kyoto, Japan.

In 2005, the Duke scientists announced that their original work caused the monkeys' brain cells to adapt. Even though the 2003 experiment showed that the monkeys could control the robotic arms as if they were moving their own limbs, it was inconclusive as to whether the monkeys' brain cells were changing in response to the task. The study two years later definitively proved that the primate brain is very adaptable, which suggests that the human brain is much the same.

If the human brain can adapt to using similar technology, then its significance for the disabled is unparalleled. Should the brain be as adaptable as the 2005 work intimates, it would allow the handicapped to experience greater independence and self-sufficiency by using these brain-operated devices to control robotic assistants or limbs. Want to know more? Check out back issues of the journal Neuroscience. Until then, let's hope these monkeys have a less mischievous inner child than George.

Bionic Arm Restores Sensation and Mobility to Amputees




It seems that reality trumps classic science fiction as new research takes the bionic arms of the Six Million Dollar Man from fantasy to feasibility. Scientists from the United States have developed an artificial hand and a groundbreaking surgical technique that work in tandem and promise to restore the sense of touch to amputees.

According to the Daily Mail, two patients have successfully undergone a surgical procedure that links the advanced prosthetic to the absent limb's nerves and reroutes the nerves to the upper torso, where they grow toward the skin surface. While the redirected nerves make the patients feel sensations from their "hands" on their chest, researchers suggest that the technique may be manipulated to offer amputees the hope of replacing lost appendages with artificial arms that simulate feelings of pressure and pain.

The patients, Claudia Mitchell, an ex-US Marine, and Jesse Sullivan, now wear the most advanced prostheses in the world after the surgery conducted by the Rehabilitation Institute of Chicago's Dr. Todd Kuiken. The surgical technique, dubbed targeted reinnervation (TR), promises to revolutionize the treatment options for amputees. Researchers hope that within a few years such prosthetic limbs may be available on a wide scale.

Equally important to the prospect of returning sensation to patients is that the treatment returns limb mobility as well. Indeed, scientists envision bionic arms available to all amputees that not only transmit sensory impressions to their wearers, but whose movement is controlled by their owner's thoughts. Ms. Mitchell is the first beneficiary of such a vision, boasting that she not only feels pain and pressure from her new arm (on her chest), but that she can peel a banana and cut steak too. The movement is made possible by the redirected nerves near the skin surface that send electrical signals to sensors on her chest and are picked up by the artificial appendage.

Curious? Read more about the prosthetic hand's amazing mobility in the medical journal The Lancet, or find more info about the surgery's potential to restore sensation in the Proceedings of the National Academy of Sciences. What's noteworthy about this latest news is that while there are a number of bionic hands now available or in development, none of them operate using real nerves that produce the most authentic sensations. Clearly, scientists aren't waiting on Arnold Schwarzenegger to leave his severed robotic arm from the future laying around for them to develop cyborg technology like they did in the 'Terminator.' It's already here.

"Robo-Moth" Gives Hope to Amputees



Further hope that victims of paralysis or amputation could one day reclaim some form of motion came this week in the form of a robotically-enhanced, tobacco-chewing moth.

The Society for Neuroscience's yearly gathering in San Diego saw a presentation on research in which a tobacco hornworm moth's brain was connected to electrodes and amplifiers at the base of a fairly common kit of robotic parts. When the insect's highly developed eyes, evolved for evading predators and mating, would shift left or right, the attached robotic parts would react accordingly.

In order to get the "robo-moth" to shift it's eyes, the scientists placed it in tube with a 14-ich tall revolving wall covered in vertical stripes. The moths, which only live about a week, would then track the stripes resulting in motion with the longest tracking time lasting nearly a minute and a half.

While limited at the moment, the device's use in harnessing electric impulses in such a small brain gives way to added possibilities from using insects as bomb-detectors to the aforementioned ambitions for practical human applications.

New "Super Mice" Run for Five Hours Without Stopping















Scientists at Case Western Reserve University in Ohio have developed a breed of "super mice."

These new mice are able to run 20 yards a minutes, for five hours, without stopping. They even have a metabolism that we're sure is the envy of all the chubby mice out there. They'll eat 60 percent more food than the average mouse, but weigh about half as much. They're also sexually active, especially later in life.

The mice even breed at an absurd rate. The researchers created their first mouse four years ago and now have a colony of 500 super mice.

The simple switch of a single metabolism gene, one that is shared with humans, caused this change.

It looks like the goal of the experiment was not to create an army of super mice, or to find a way to genetically modify human beings for better athletic performance, but to maybe help heal human injuries faster. That said, the researchers said that creating drugs or treatments to "enhance" athletes' natural abilities was not out of the question.

Hovercraft + Airplane = Hoverwing

Hoverwing Takes Flight, Crashes, Will Rise Again

The flying car is finally approaching reality -- maybe -- but inventors around the world are still working to combine other vehicle types to come up with a more efficient (and fun) means to get from point A to point B. Such is the case with Rudy Heeman, an inventor in New Zealand who has created a device called a hoverwing.

Like other similar craft we found on YouTube, Rudy's hoverwing is a combination of a hovercraft and a plane. It's capable of zipping around on the surface of land or water, cushioned by a pillow of air. But when it reaches 60mph, its wings extend and the thing is able to fly about six feet above the surface. It's taken 11 years of Rudy's life and an untold amount of money to create the thing. And despite the first flight ending in a crash, Heeman hasn't lost his motivation. In fact, he's looking for a volunteer to join him on the second flight.

Any takers? Count us out. This thing doesn't look any safer than those killer flying kite tubes.
