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

Body suit simulators are nothing new. Earlier this year the Kanagawa Institute of Technology in Japan unveiled Mommy Tummy 8.0, designed to help the partners of expecting moms--as well as teenagers thinking about getting it on--to understand the physical ramifications of, well, getting it on.

Now students at MIT's AgeLab are taking this empathy concept to another level with AGNES, the Age Gain Now Empathy System, a suit designed to help wearers understand the physical ramifications of neglecting our bodies for decades on end. (AGNES is meant to emulate a 75-year-old with arthritis and diabetes.)

The suit incorporates shoes that compromise one's sense of balance and shorten one's gait; knee and elbow braces that limit joint mobility; earplugs that tune out soft or high-pitched sounds; a helmet that compresses the spine; and gloves that reduce not only strength and mobility in one's hands and wrists but also tactile sensation.… 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

It's been a good year for video gamers--and not just the epic legions of Call of Duty fans enjoying Modern Warfare 3.

A few months after Foldit players helped decode the structure of a protein key to the way HIV multiplies, another group of gamers taking on DNA sequencing in the game Phylo have contributed more than 350,000 solutions, the game's designers at McGill University report.

When University of Washington researchers unveiled Foldit in 2008, it wasn't clear whether the protein-folding game would be a one hit wonder. But one-year-old Phylo, already averaging 1,000 eureka … Read more

Tracking where humans migrate and cluster in any given country from season to season is, in some places, a tall order. Which makes tracking the risk of infectious disease outbreaks that thrive in dense populations tricky as well.

Satellite images of nighttime lights could be the answer, according to researchers at Princeton, who report on their findings today in the journal Science.

Using nighttime images taken of Niger's three largest cities between 2000 and 2004 by a U.S. Department of Defense satellite, and checking those images against public health records compiled by Niger's Ministry of Health, they … Read more

Researchers around the world have been studying a group of recently-identified antibodies capable of neutralizing most strains of HIV, with the hopes of developing a vaccine that produces antibodies with these same properties.

Now, biologists out of the California Institute of Technology--led by Nobel Laureate David Baltimore--are one step closer to a vaccine with their new method of delivering these antibodies to lab mice, thereby protecting them from HIV.

Their approach, called Vectored ImmunoProphylaxis (VIP) and outlined in today's online issue of Nature, turns the traditional vaccination method on its head.

For the most part, researchers have focused … Read more

Traditionally, doctors and midwives have used a technique called pelvimetry to measure the pelvis and try to determine its adequacy for giving birth. But pelvis size is just one factor in how smoothly labor will go, rendering the method largely insufficient.

Scientists in France have been working to take some of the guesswork out of labor predictions. Today, at the Radiological Society of North America's annual meeting, they are presenting results of a study showing that their newly developed software, called Predibirth, predicts birth outcomes quite accurately.

The researchers used their software to process magnetic resonance images of 24 … Read more
