Smartphone display could improve eye diagnoses

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

World's fastest camera detects elusive cancer cells

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 snoozes in high-tech compression jammies

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

Researchers a step closer to 'printing' new blood vessels

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

My life as a cyborg

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

Brain scans may detect autism in babies and toddlers

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

Scientists release first 'cinematic MRI' of live birth

Let's get one thing straight up front: the term "cinematic" does not in this instance mean it's time to order up some popcorn. There's no color, no dramatic score, no super slow-mo to announce the climax. This is gritty black-and-white footage of a woman giving birth.

But don't let the grit fool you into thinking it's low tech. The world's first birth in an MRI machine was announced by scientists at Charite University Hospital in Berlin back in December 2010, and they're only now releasing the 25-second video, which was made … Read more

How to keep your iPad free of bodily fluids

I like to think I'm no germaphobe, but when I was recently handed an iPad whose screen was littered with smudgy fingerprints, a little voice inside my head stopped talking and started choking. I couldn't help but imagine what pathogens were thriving on that surface.

Enter the AirStrap Med, an iPad case designed by and for health care workers but well-suited to the germ-wary as well.

The $89.99 case, released this month by Griffin, is made of a two-piece polycarbonate and silicone frame that snaps around the iPad (also compatible with iPad 2) in such a way … Read more

3D computer model helps screen millions of chemo drugs

Researchers have long used still images of proteins known to be related to recurring cancers in an attempt to understand exactly why these proteins make some chemotherapies fail.

Now, biochemists at Southern Methodist University are using a 3D computer model of the human protein P-glycoprotein -- believed to play a pivotal role in the failure of chemotherapy in many recurring cancers -- to screen more than 8 million potential drug compounds in the hunt for one that will help stop this failure.

"This has been a good proof-of-principle," biochemist John G. Wise said in a school news release. &… Read more

Internet usage patterns may signal depression, study finds

The amount and type of online activity Internet users exhibit may be indicators of depression, findings a group of researchers hopes will lead to software tools to help identify depressive behavior.

People who showed symptoms of depression tended to use the Internet differently than those who didn't show signs of depression, researchers said in a New York Times opinion piece today. Some of that behavior included obsessively checking e-mail, watching lots of videos, and switching frequently among multiple apps, according to a new study by researchers from the Missouri University of Science and Technology.

The researchers asked 216 college … Read more
