LAS VEGAS--A considerable line of CES attendees who must have just imbibed their morning coffee is forming at the Toddy Gear booth. They're clutching what look to be colorful washcloths and feverishly wiping their various touch screens.

The Consumer Electronics Show is only halfway through, but in the right light these screens have obviously been stuck in some sort of fingerprint purgatory, perhaps not thoroughly scrubbed since long before being used voraciously in Vegas for directions, schedules, gossip, and who knows what else.

The fuss is over a product almost laughably simple, the 5x7-inch antimicrobial Toddy Smart Cloth, one … Read more

LAS VEGAS--If you've been pining for a continuous heart rate monitor that doesn't strap onto (and continually pinch or slide down) your chest, the new company Basis Science may have just the solution for you, and it doubles as a sleek little watch.

The Basis Band, one of this year's dozen or so CES Health and Wellness Innovations Awards honorees, is equipped with multiple sensors that track not only heart rate (using optical blood flow sensors) but also activity level (via 3D accelerometer), calories burned, and temperature and galvanic skin response.

The water-resistant black or white band … Read more

At CES, scientific-equipment giant Life Technologies unveiled a DNA sequencer designed to decode an entire human genome in a day for $1,000 by the end of 2012.

The Ion Proton Sequencer, priced at $149,000, isn't your typical hot commodity on the show floor. But the benchtop sequencer costs far less than its bulkier, slower predecessors (typically in the $500,000 to $750,000 range), and the $1,000 price tag--once costs fall to that level--could put personal gene sequencing directly into the hands of the masses.

"This is such an amazing moment in history," said … Read more

The "Star Trek" universe may be beloved by millions, but it's entirely fictional. Yet one element of Gene Rodenberry's timeless creation may actually help people with their health care decisions in real life.

The problem faced by millions of people around the world, especially in the third world, and in rural areas of the first world, is that there's not always a doctor around to help figure out what's wrong with you--and sometimes, one isn't even necessary. Sometimes, the right technology could help us determine what's going on in our bodies.

That'… Read more

If researchers at the University of Illinois have their say, bandages are about to get a whole lot cooler.

A team of engineers has created a bandage that in just one week not only encourages new blood vessel growth but helps guide that growth as well.

"The ability to pattern functional blood vessels at this scale in living tissue has not been demonstrated before," co-principal investigator and electrical and computing engineering professor Rashid Bashir says in a school news release.

The team, whose findings will grace the cover of a January 2012 issue of the journal Advanced Materials, … Read more

The world is changing fast--maybe faster than we ever thought. And within five years, science fiction is going to turn into non-fiction. We'll be able to read each other's minds, forget all our passwords, and create all our own homes' energy.

These are just three of the five predictions IBM announced this morning as part of its annual "5 in 5" prognostication project.

The list is meant to promote long-term work being done under Big Blue's Smarter Planet initiative--and the company says "5 in 5" already has a track record of success. In … Read more

It's often the case that a device or substance with a known benefit also comes with known risks--typically referred to as side effects and listed quickly at the ends of commercials. So it seems worth noting when a product's side effect may in fact be useful.

The Valkee, a portable headset launched in August of 2010, directs 8- to 12-minute doses of bright light through the ear canal and into the brain to improve seasonal affective disorder. It turns out that this concentration of bright light into the brain may also improve motoric reaction time, according to a study conducted by Verve Research in Finland.

The placebo-controlled study (meaning some were given the treatment and others a placebo in its place) tested the effects of the Valkee headset on Finnish national league ice hockey players and found that those exposed to 12 minutes of light via the headset sped up their already fast reaction times by 20 percent.

"The placebo-controlled study showed a significant improvement in motoric reaction times of top athletes using bright light via the ear canal," says lead researcher Mikko Tulppo in a news release.… Read more

Patches of tiny needles have already been shown to effectively deliver medications painlessly, and without a bloody mess. Now the tiny needles could also be used to monitor body chemistry in real time.

The new tech, developed by a team of biomedical engineers out of North Carolina State University, the University of California at San Diego, and Sandia National Laboratories, employs electrochemical sensors in the hollow channels of microneedles to detect certain molecules. The researchers reported their findings in the chemistry journal Talanta.

Current body chemistry monitoring involves taking samples, often before or after an event. Wearable micro-sensors, on the … Read more
