Robotic prostheses may have a way to go before they work exactly like human limbs, but researchers are making great strides. A team out of Georgia Tech is working on new technology that could give these robotic limbs something akin to a sense of touch.

Thanks to tactile-sensing material that covers the entire prosthesis and software that integrates the gathered data, this robotic arm can maneuver through clutter and distinguish between hard and soft objects as it grips, pushes, and pulls more intuitively.

"Up until now, the dominant strategies for robot manipulation have discouraged contact between the robot's … Read more

To my fellow geeks who've long dreamed of having a lab-quality digital microscope that mounts to your phone, the time has come.

Oregon-based optics manufacturer Bodelin will begin shipping its brand-new ProScope Micro Mobile on May 1. One version fits the iPhone 4, 4s, 5, and iPod Touch; another the iPad; and another the iPad Mini. Whatever size, it will set you back $149.… Read more

Some people drive high.

They shouldn't, but they're high, so they don't really know what's good for them and what isn't.

Should they get stopped by police, the long nose of the law can sometimes sniff the presence of marijuana in their car.

Should they happen to have nosed their way into some cocaine, there might be traces of white powder around their nostrils.

As yet, though, there hasn't been a machine that can detect the presence of such drugs on one's breath, as there is for alcohol.

Scientists in Sweden, however, believe they have made some progress in creating such a device.… Read more

Using what they are calling "mechanical agitation," researchers out of the Georgia Institute of Technology say they've developed arrays that can sense touch with the same level of sensitivity as the human fingertip, which could result in better bots and prosthetics.

The transparent and flexible arrays use about 8,000 taxels, which are touch-sensitive transistors that can generate piezoelectric signals independently -- meaning they emit electricity when mechanically agitated. As the researchers report this week in the journal Science, each of those thousands of transistors comprises a bundle of some 1,500 zinc oxide nanowires, which connect … Read more

An interaction designer who makes sci-fi short films has spent the past three years developing what he says is the world's first Braille-enabled smartphone. He said that if testing goes well, the phones could hit stores by the end of this year.

Thanks in part to award money from Rolex, India-based designer Sumit Dagar has been collaborating with the Indian Institute of Technology Delhi and L V Prasad Eye Institute in Hyderabad to develop a prototype. The smartphone employs a haptic touch screen that elevates and depresses the content it receives, thereby transforming the data into touchable patterns.

Yes, this phone is essentially a shapeshifter.… Read more

The victims of the Boston Marathon bombing may have to live with the physical and emotional scars from the April 15 attack for the rest of their lives. For some of the injured, that includes learning how to live without one or more limbs.

More than 180 people were injured in the attack last week, with at least 13 people losing a limb or part of one. Right now, doctors are focused on recovery and making sure the victims are medically stable. But once the wounds heal, many of the patients will begin the process of being fit with a prosthetic device.

"This is not just about learning how to walk," Steve Fletcher, CPO, director of clinical resources at the American Board for Certification in Orthotics, Prosthetics and Pedorthics, told CBSNews.com. "It's a significant emotional, psychological, and physical recovery."

For the roughly three percent of the population that suffers from amblyopia, or "lazy eye," the best current treatment option -- covering the stronger eye to force the weaker one into better behavior -- works only some of the time in kids and has been totally ineffective in adults.

Now researchers out of McGill University in Montreal say that playing Tetris may ultimately treat the disorder in adults because the puzzle video game trains the eyes to work together as information is distributed across them in a complementary fashion.

"The key to improving vision for adults, who … Read more

A researcher who used to work in digital television has just led a team of Columbia University engineers to win the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge.

Dimitris Anastassiou, who is now a systems biologist (meaning he investigates interactions within biological systems), reports in the April 17 issue of Science Translational Medicine that his team's winning computation model is extremely predictive of breast cancer survival.

Before the challenge, Anastassiou and his team identified what they call "attractor metagenes," which are genetic signatures expressed in almost the exact same way across many types of cancer. Their new … Read more

When HapiFork first debuted at the Consumer Electronics Show in January, the brightly-colored, vibrating fork caused a stir, landing press coverage from all over the world, including a mention on The Colbert Report.

Basically, the fork vibrates if you eat too fast. Some folks thought the fork served a useful purpose -- getting users to eat more slowly -- while others thought it was just a novelty. It is a vibrating utensil, after all.

The folks at Hapilabs, the company behind HapiFork, say they're just glad people are talking about the fork at all because that means there's … Read more
