You might think you can't have a phone conversation with someone who's deaf, but Dimitri Kanevsky would not only disagree, he'd prove you wrong.

Deaf since he was 3, Kanevsky has hardly let his disability get in the way of progress -- or success. Born in the Soviet Union, he eventually emigrated, first to Israel, and then to the United States, and went on to become a research staff member in the speech and language algorithms department at IBM's Thomas Watson Research Center.

On Monday, Kanevsky and 13 others were honored at the White House in … Read more

A group of researchers says shoes may be the next thing in the busy field of wearable computers and gesture interfaces.

Computer scientists from the Telekom Innovation Laboratories, the University of Munich, and the University of Toronto this week published a paper on ShoeSense, a wearable computing system for a smartphone.

It's one of many gesture interface-related papers being presented this week at the Conference on Human Factors in Computing Systems (CHI 2012) conference, which is sponsored by the research arms of Microsoft, Google, eBay, and other tech companies.

Wearable computing got a high-profile plug when Google introduced Project Glass, … Read more

Within a couple years, a single exhale may tell us more about our personal health than merely the current state of our oral hygiene -- and without relying on dogs to sniff out our problems.

The answer lies in a device called the Single Breath Disease Diagnostics Breathalyzer. Back in 2010, Stony Brook University researcher Perena Gouma began testing an earlier iteration in preclinical trials; for use with diabetes patients; now she has developed a sensor that might enable the detection of a range of diseases in a single exhale.

The sensor, which lives in a device about half the … Read more

In 2010 Brian David Johnson became Intel Corp.'s first futurist, a time-honored title bestowed on prognosticating technology mavens dating back to the likes of Jules Verne and H. G. Wells. Equal parts seer and evangelist, Johnson helps map out the future of technology and then guides his company toward that destination, whether it is five years or even a decade away.

Johnson draws inspiration from science fiction but tries to ground his vision of the future in reality through speaking engagements in front of audiences most likely to be affected by Intel's technology, such as attendees of the … Read more

In what could be a major boon for the study of brain disorders such as schizophrenia, Parkinson's disease, autism, and epilepsy, researchers at MIT and Georgia Tech say they've figured out how to automate finding and recording information from neurons in live brains.

The process, described this week in the journal Nature Methods, involves a robotic arm guided by a cell-detecting algorithm that can identify and record data from neurons faster and more accurately than we mortal humans.

"In all [the abovementioned disorders], a molecular description of a cell that is integrated with [its] electrical and circuit … Read more

With more patients needing heart transplants than there are hearts available, a tiny heart pump called a ventricular assist device (VAD) can be a lifesaver. But the pump, which is inserted into the aorta via a catheter that helps blood flow, requires wiring leads that run out of the patient's body to a battery pack, and this setup can easily result in infection.

So a team of computer and electrical engineering students at Rice University have devised a method to power the VAD without wires breaking through the skin.

The team used a small coil and a battery inserted … Read more

Where do you find inspiration for your work? Robert Full, a professor at University of California at Berkeley, and his team looked to lizards when it came to thinking of ways to better design robots for search and rescue missions.

Such robots have to be more agile. So Full's team studied the movements of a red-headed Agama lizard and discovered the importance of having a tail.

"I think what this shows is that even the strangest creature that we think has nothing to offer really holds fundamental secrets of how things work, and those can be translated to … Read more

When a 15-year-old boy was shocked -- to death -- by a Taser stun gun in Michigan in 2009, Amnesty International called for rigorous testing of the weapon, which delivers an initial 50,000-volt shock.

"There have to be ways of restraining an unarmed teenager other than using electro-shock weapons," the organization said in a statement. "Taser guns are not the safe weapons they are portrayed to be. A full investigation into their safety needs to be carried out before more people suffer the consequences of their misuse."

Now, two research papers are weighing in on … Read more

If you missed it last year, the super perigee moon is back for an encore performance.

On Saturday, the moon will be up to 14 percent bigger and 30 percent brighter than the other full moons of 2012, according to NASA.

That's because it will reach perigee, its closest point to Earth in its elliptical orbit, at 11:34 p.m. ET and become full just a minute later.

Super perigee moons happen about once a year on average, but the moon of March 19, 2011, was nearly 250 miles closer than this week's moon, prompting wild calamitous speculations. … Read more
