"The laughter felt loud," said Sarah Churman.

It's impossible for anyone who isn't deaf to even imagine how it might feel to hear laughter for the first time. Or, indeed, your own voice.

Yet Churman's husband decided to film the moment. He then posted it to YouTube.

In the notes to the video, Churman explained that hearing aids only help so much. Eight weeks ago, however, she was given an Esteem implant, made by Envoy Medical.

The device itself is placed behind the ear and no part of it is visible. It doesn't have … Read more

Houston, we have a health problem.

About 30 percent of adults in the U.S. have at least two chronic health conditions. Roughly half of a panel of surveyed patients are not complying with doctor's orders. And more than half of Americans could be obese by 2030.

In the coming years it's going to be more important than ever for doctors' offices to be able to automatically track their patients across a variety of parameters, from age and ethnicity to conditions and diseases, and even to compliance levels. Dallas-based health management firm Phytel is hoping that the platform it's unveiling today … Read more

On today's show we're covering an emerging tech trend: The Quantified Self movement, or the collection of data streams about what we do, how we feel, how we move, and so on. Why? That's one of the big questions. The best answer is probably: to live better lives. And today we're talking with two entrepreneurs who are working on a subset of the quantified self movement: body monitoring. Both their companies have the goal of making us more aware of ourselves. Using that knowledge, hopefully, we can live more healthy lives.

Our guests are Monisha Perkash, CEO of Lumoback, which I covered this week from the Demo conference, and Jef Holove of Basis, which I wrote up in July.

There hasn't been another major radioactive leak, but soon we could see flesh wounds glowing in the dark. Researchers at the University of Sheffield in the U.K. have developed a gel that glows under ultraviolet light when it comes in contact with many kinds of bacteria.

The gel also appears to be effective in fighting the bacteria at the same time.

"The polymers (in the gel) incorporate a fluorescent dye and are engineered to recognize and attach to bacteria, collapsing around them as they do so," Sheffield Professor Sheila MacNeil explains in a statement. "This change in polymer shape generates a fluorescent signal that we've been able to detect using a handheld UV lamp."

Project lead Dr. Steve Rimmer adds that the technology could help reduce the overuse of antibiotics. In testing, the gel has been able to detect the presence of serious bacterias including Salmonella, E. Coli, MRSA, and meningitis.… Read more

Google continues its growing tradition of celebrating scientific and cultural pioneers who might not be household names, but whose work is part of our daily lives. While today's citrus-filled doodle on the search engine front page first appears to indicate that Google has sold out to Tropicana, it's actually a tribute to Albert Szent-Györgyi's 118th birthday.

What, you weren't already taking the day off to celebrate? In case you're not in the know, Albert, whose full name is Albert von Szent-Györgyi de Nagyrápol, is the person credited with discovering Vitamin C and the citric acid cycle. That work earned him a Nobel Prize in 1937. He was also one of the first to look into connections between free radicals and cancer, and according to the U.S. National Library of Medicine, "his discoveries about the biochemical nature of muscular contraction revolutionized the field of muscle research."… Read more

SANTA CLARA, Calif.--It's a stretch to say the Lumoback app made the audience at Demo sit up and take notice, but it was one of the most unusual pitches here at the conference.

Lumoback monitors your posture. All you have to do is stick a little flat sensor on your lower back (stay with me, here), and install the companion app on your mobile, and it will gently nudge you when your posture slacks.

There are additional game and social mechanics that go along with this data. Because we all want to join a social network of people who have giant pains in their necks.

Now, to be fair, back pain and back-related injuries do cost the U.S. $50 billion a year, according to CEO Monisha Perkash. And minor adjustments in posture can make a big difference in keeping us out of the medicine cabinet--or worse, the doctor's office.

And, as one of the VC judges said after this presentation, this kind of thing could sell really well on TV shopping channels. Not to mention through prescription channels. And it is pretty cool that a cheap wireless sensor and a free app can keep people healthy. If they use it. Which most won't, of course.

Still, gutsy play. … Read more

The best thing I saw at CES in 2010 was the Parrot AR Drone, an iPhone-controlled quadcopter. It was a really fun toy, but an expensive one, and not that reliable either, as I learned when my demo unit dropped out of the sky. But this platform, the quadcopter, can be a serious player in solving real-world problems. Aeryon, which I covered in 2009, played an important part in the Libyan rebellion: one of its flying bots helped the rebels see over their heads to where their opposition was gathering.

And at the graduation ceremony of the Singularity University this week, I was introduced to another real-world, save-the-world company that's applying quadcopter technology: Matternet.

This particular class of S.U. was focused on solving problems for "the next billion people," those without access to modern technology. Matternet tackled the problem of getting drugs and diagnostic or test materials to people in rural areas in developing countries that don't have access to passable roads during rainy seasons.

The company proposed building a network of robotic drones to deliver medication quickly and very cost-effectively--even less than a guy on a dirt bike costs.

If you're going to try to help people figure out the best foods for their individual circumstances, why not bring a little Silicon Valley sensibility to the table?

That's the thinking of ShopWell, a Palo Alto, Calif.-based start-up that's hoping to become a major player in the ever-growing personal nutrition recommendation arena with a high-tech matching algorithm.

Founded by Brian Witlin, a former entrepreneur-in-residence at leading design consultancy IDEO, ShopWell is aiming to give individual shoppers Web- and mobile-based applications that offer the best possible suggestions about what groceries to buy based on their own personal … Read more

Combine the words "vibrator," "touch," and "heightened sensitivity," and the subject is obvious, right? A tricked-out glove that heightens your sense of touch.

The glove, developed by Georgia Tech researchers, includes a tiny vibrator that sits on the side of your finger. Turn the vibrator so low that you don't quite notice it vibrating, and voila, your fingertip is more sensitive to touch.

Prototype tests showed that the heightened-sensitivity glove enabled people to sense lighter touches and distinguish sensory points that were closer together than they could without it. People correctly distinguished among different fineness levels of sandpaper 15 percent more often with the glove.

The glove could help surgeons and others who rely on a fine sense of touch, and it could help people with an impaired sense of touch.… Read more
