Could goggles hold key to detecting strokes early?

Testing for strokes can be inaccurate and expensive. But a new device that looks like a pair of swimming goggles may offer a better, cheaper alternative, and save tens of thousands of lives every year.

The goggles, equipped with an infrared camera attached to a cord that goes to a laptop computer, measure eye movements, Dr. David Newman-Toker, an associate professor of neurology at the Johns Hopkins University School of Medicine, explained on "CBS This Morning."

"The eye movements (when) patients present with strokes in the back part of the brain -- and that's about one out of every four strokes -- the patients present with dizziness and vertigo and we can tell from their eye movements whether they've had a stroke or whether they have a benign inner-ear condition, quickly and easily," said Newman-Toker, who is leading the study of the new technique.

The goggles will work best as strokes occur, Newman-Toker said, and will likely find use in emergency rooms. … Read more

Canon video sensor prototype can see in the dark

Canon has developed a video sensor that can capture images illuminated only by a glowing incense stick or the light of a crescent moon.

The sensor gathers light by using extremely large pixels -- 7.5 times the surface area of those in the 18MP EOS-1D X professional SLR, whose 35mm full-frame sensor is the same size. In conjunction with that approach, "the sensor's pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases," Canon said in its announcement.

IBM app marries augmented reality, comparison shopping

HANOVER, Germany--IBM showed off technology today designed to let people use their smartphones to take command of their real-world shopping.

Big Blue showed an app idea from IBM Research in Haifa, Israel, that uses image recognition to identify products on store shelves, then lets people sort those products by attributes such as price and nutrition information. A customer could select only gluten-free products, pick food that's from nearby, or filter electronic gadgets by operating system.

"The same experience people expect online is available in the store," said Amnon Rebak, a research staff member on the project, at … Read more

Two-year-old infected with HIV 'functionally cured'

In an unprecedented case, doctors in Mississippi believe they have "functionally cured" a toddler of an HIV infection.

Recent tests of a 2-year-old born premature with the disease show no detectable levels of the virus, according to the National Institutes of Health. Doctors credit early administration of antiretroviral therapy for curing the child, who shows no signs of the virus after a year off the drugs.

"Despite the fact that research has given us the tools to prevent mother-to-child transmission of HIV, many infants are unfortunately still born infected," Dr. Anthony S. Fauci, director of National … Read more

Scientists link rats to real-world 'Matrix' via the Internet

There is officially a Wachowski Brothers-style "Matrix" for rodents.

Scientists in North Carolina and Brazil have connected the brains of two rats using "brain-to-brain interfaces" that can connect directly or via the Internet. These allow the rodents to share sensory information, collaborate on tasks to earn rewards, and fight back against the shadowy and cyber-apocalyptic forces that have enslaved them.

There's actually no evidence of the latter, but I'd still suggest researchers watch out for any rats that start displaying a propensity for martial arts.… Read more

Get a ball's-eye view with camera in football

Do you really have enough camera angles when you watch a football game? Come on, you want more.

Feed your desire to be omnipresent with the wacky BallCam. It puts a camera inside the spinning football.

You'd think that would make you toss that mix of pizza, hotdogs, and beer in your stomach, but boffins at Carnegie Mellon University and Japan's University of Electro-Communications have made it a rather pleasant viewing experience.

CMU researcher Kris Kitani and UEM's Kodai Horita co-authored a paper on how algorithms in their prototype football can recognize footage of the ground as … Read more

Leap Motion controllers to ship in mid-May for $80

Leap Motion, which has developed an innovative motion-control system that's accurate to the hundredth of a millimeter, said today that it will begin shipping its controller on May 13.

The controller, which gives users the ability to control what's on their computers with touch-free pinch-to-zoom gestures, will sell for $80 -- though customers who have already pre-ordered it will pay $70 -- and will ship to pre-order customers on May 13, and be available to everyone else on May 19.

The device will be available in the U.S. only through Leap Motion's Web site, and at … Read more

Inventor gets off the ground with homemade jetpack

It might look like a recipe for disaster, or at least a trip to the hospital, but a German inventor is trying to take to the skies with a jetpack that's designed to race along a runway before flying.

Inspired by daredevil Felix Baumgartner, Fritz Unger wants to soar like a bird by strapping wings and two jet engines to his back.

That hasn't happened yet, but his Skyflash jetpack has lifted him off the ground for an instant as he rolled along at 34 mph. … Read more

FDA approves single-lead implantable cardiac defibrillator

Cardio med tech company Biotronik today announced Food and Drug Administration approval of the world's first implantable cardiac defibrillator that uses just one lead to sense atrial arrhythmias.

Say what?

For those unfamiliar with the mechanics of the heart, let's back up. Atrial fibrillation (AF), the most common heat arrhythmia, occurs when the electrical signals in the atria (the heart's two upper chambers) fire fast and frenetically, causing the atria to essentially quiver instead of pulse regularly, which can result in blood pooling or clotting and thus greatly increase the risk of stroke and congestive heart failure.… Read more

Researchers develop flexible, transparent image sensor

Researchers from the Institute of Computer Graphics at Johannes Kepler University in Linz, Austria, have developed a way to capture images on a flexible sheet of plastic. Unlike traditional image sensors that use circuits and other internal structures to develop an image, this new solution is fully transparent.

This is no ordinary sheet of plastic though. The sensor is a polymer film (luminescent concentrator) containing a multitude of fluorescent particles that absorb a specific wavelength of light. It then transmits this light at a longer wavelength to optical sensors at the side of the sheet, which captures it all, reconstructing … Read more
