Researchers are reporting that they have found, for the first time, that tiny electrical spinning tops ("rotors") within the heart cause atrial fibrillation (AF), a type of arrhythmia in which the heartbeat is faster and irregular.

What's more, they found that by targeting the so-called eye of the storm, they could actually slow or even terminate the AF, the multidisciplinary team from UC San Diego, UCLA, and Indiana University reports in the July issue of the Journal of the American College of Cardiology.

Today, catheter ablation is a common therapy used to treat AF, but because the … Read more

A wireless musical glove developed at Georgia Tech not only teaches users to play songs on the piano, but may also improve the sensation and mobility of the hands of people who have suffered spinal cord injuries, researchers report.

The Mobile Music Touch (MMT) device, which works alongside a computer and a keyboard, improved rehabilitation even in patients who had sustained the injury more than a year earlier -- a point at which improvements tend to be minimal at best.… Read more

Got a new mole? A bad sunburn? A family member with a skin cancer diagnosis?

UMSkinCheck, a free new app for iPhone and iPad developed at the University of Michigan, includes a risk calculator that will help you determine your individual risk. If you have any concern at all, it guides you through taking a series of 23 photos that cover your entire body to develop a baseline for future photo comparisons.

"Whole body photography is a well-established resource for following patients at risk for melanoma," Michael Sabel, lead physician in app development and associate professor of surgery … Read more

Smartphones could soon be used not only to view complex inner-eye photos for diagnoses, but also to take, send, and view pictures of damage to the front of the eye or to eyelids, according to a new study out of Emory University.

Smartphones may even make passe those annual eye doctor visits if their imaging is good enough for diagnosing and planning treatment for a range of eye conditions -- good news for those who, like myself, prefer to perform as many chores as possible (think shopping) from the comfort of my home.

The researchers at Emory collected data on … Read more

Modifications to the world's fastest camera are enabling the real-time identification of rare breast cancer cells in blood, with a record low false-positive rate of one cell in a million, according to new research out of UCLA.

"This technology can significantly reduce errors and costs in medical diagnosis," lead author Keisuke Goda, a UCLA program manager in electrical engineering and bioengineering, said in a school news release.

The team's approach could not only pave the way for earlier detection of cancer and monitoring of drug and radiation therapy but also prove useful in urine analysis, water … Read more

Michael Phelps isn't like most people, so it stands to reasons his pajamas aren't like most people's. There are no fuzzy bunny slippers and sheep-print flannel pjs for Phelps. He wears a high-tech compression suit from Under Armour.

The Recharge Energy Suit is a full-body suit designed to help the body recover from fatigue after training.

Under Armour claims the super tight compression fit pushes out the water damaged muscle fibers take on when sore, leading to a faster recovery. This is also probably as close as you'll get to knowing what it feels like to be swallowed by a snake.… Read more

Vascular systems -- i.e., networks of blood vessels -- are like highways for the delivery of nutrients and removal of waste; without them, cells die quickly. The ability to bioengineer new vasculature is a crucial step toward creating new replacement organs such as livers or kidneys from a patient's own cells.

Bioengineers are already working on creating and assembling single layers of cells that have direct access to nutrients and oxygen -- a process known as "bioprinting." But creating a full-fledged array of new vessels remains a major hurdle. Fluidic pressure coursing through these tiny systems … Read more

SEATTLE -- It was an unseasonably warm June evening, the kind of day locals rave about because they come so rarely. At 6 p.m., I hopped on my bike for an evening spin.

My heart-rate quickly raced up to 157 beats per minute as I picked up my pace to 14 miles per hour up a gradual rise in the road. At the same time, my blood-glucose level dropped to 62 milligrams per deciliter, low, but not dangerously so for a non-diabetic. All in all, pretty solid data, given that the night before I slept six hours and 21 minutes, waking for brief periods 21 times during the night.

Welcome to my cyborg life. Google has generated tons of press in recent days with its Project Glass, computerized glasses that lets users take pictures and find information. But it's hardly the only company pursuing wearable computing. And while Project Glass won't be commercially available for another two years at the earliest, there are plenty of companies selling devices that consumers can slip into and strap on to collect reams of data about their daily lives.

To get a glimpse of that future, I strapped on a bunch of those gadgets. Here's what I learned.… Read more

Two separate studies published this month indicate that it may be possible to use brain imaging techniques to reliably detect autism in children as young as 6 months of age.

In the first study, published in the American Journal of Psychiatry, researchers from across North America working on the larger and ongoing Infant Brain Imaging Study used a type of MRI called diffusion tensor imaging to study 92 6-month-olds deemed high risk because their older siblings had been diagnosed with autism.

What they found is that the organization of white matter in the brain plays a key role. Specifically, they … Read more
