Researchers at the University of Michigan say they have developed a simple litmus-like test for nerve gas that could clue military personnel into when they might actually need to use those heavy masks and protective gear. (Nerve gases, the most toxic of chemical warfare agents, and are colorless, odorless, and tasteless.)

"To detect these agents now, we rely on huge, expensive machines that are hard to carry and hard to operate," Jinsang Kim, an associate professor of materials science and engineering at the University of Michigan, said in a statement. "We wanted to develop an equipment-free, motion-free, … Read more

An estimated 1.5 million Americans have Parkinson's disease, which causes slowness of movement, tremors, and loss of balance. Physical therapy can ease symptoms and may delay progression of the disease. Now, cutting-edge tech is transforming everyday therapy into entertaining exercises.

Parkinson's patients recently took part in a University of California at San Francisco study to see if special video games could replace their regular exercises. Scientific researchers and game developers came together to create the therapeutic games. Check out this SmartPlanet video that explores the technology.

This video originally appeared on SmartPlanet with the headline "Video games replace physical therapy for Parkinson's patients.&… Read more

Many of us have never been properly trained on how to do or use certain things we really should be good at. Putting on condoms and installing infant car seats are just two skills that come to mind; when we get them wrong, the health consequences can be grave.

The same can be said for improper asthma inhaler use--a serious and expensive problem considering some 5,000 people visit the emergency room due to and 11 people die from asthma every day, according to the Asthma and Allergy Foundation of America. Let's face it: some devices could use training wheels.

Enter the T-Haler, a digital asthma inhaler training device developed by researchers at Cambridge Consultants. Patients can use the inhaler and, via interactive software linked to the wireless device, get real-time visual feedback on the areas that need improving.… Read more

Affordable paper sensors aren't exactly new. Think home pregnancy tests. But researchers out of the University of Texas at Austin are pushing (or is it folding?) the envelope with their origami-inspired 3D paper sensor that, thanks to strategic folding, can identify more substances in more complex tests.

Able to be printed at less than a dime a sensor using an ordinary office printer and less than a minute of folding, the origami Paper Analytical Device (which they've dubbed oPAD) "is about medicine for everybody," said Richard Crooks, a chemistry professor who built the sensor with doctoral student Hong Liu, in a school news release.

Liu was first inspired to use origami when he read a paper by Harvard chemist George Whitesides, who is the first to build a 3D microfluidic paper sensor to target biological agents.… Read more

For the blind and visually impaired, it can be nearly impossible to follow along when a math teacher spends most of a lecture in front of a blackboard or projector drawing shapes, parabolas, X-Y planes, and other visuals.

It's about time there's an app for that, thought mechanical engineering grad student Jenna Gorlewicz, who'd spent a few years at Vanderbilt's Medical and Electromechanical Design Laboratory miniaturizing endoscopic robotic capsules and was looking for a more people-oriented project.

So Gorlewicz, who says she loves both teaching and math, set out 18 months ago to try to develop a tablet app that uses haptic (or tactile) technology to help the visually impaired learn math and other subjects with a strong visual component.… Read more

As a first-time expecting mother who doesn't know many kids, setting up my home for a baby is a mysterious process that involves procuring little outlet covers and stacking wine bottles on the counter instead of the floor.

As for maximizing my home's environment for optimal infant motor development, let's just say I'm the aunt who assumes a newborn can play with tangrams (turns out they just chew on them).

So this morning I rather eagerly checked out a new online test that assesses the quality and quantity of motor development opportunities my home currently provides. … Read more

When a 32-year-old man crashed his all-terrain vehicle without wearing a helmet, he slipped into a coma for three weeks. Though his initial CT scans revealed bleeding and swelling, and an MRI scan a week into the coma revealed bruising and swelling in the same area, neurosurgeons had no way of knowing precisely how the man would be affected if he did come out of his coma.

Three weeks later, the man awoke without the ability to move his left leg, arm, or hand. Only then were doctors able to begin planning rehabilitation.

Fortunately for the patient, a novel imaging … Read more

With oral sex on the rise, oral cancer is also up, and by as much as 25 percent in the past few years alone--particularly among otherwise healthy 30- to 50-year-old nonsmokers, according to Mayo Clinic researchers. That's the bad news.

The goods news is that this rise is largely attributed to types of oral cancer caused by the human papillomavirus, or HPV, which tend to be less aggressive and more responsive to treatment than the oral cancers traditionally seen in older patients who have been smoking and/or drinking for decades. What's more, the most common, called oropharyngeal cancer, … Read more

In an effort to quickly and efficiently map the roughly 5,000 automated external defibrillators (AEDs) in public areas of Philadelphia, researchers at the University of Pennsylvania's Perelman School of Medicine recently launched a contest to award $10,000 to the team or person who finds the most.

With the six-week contest, which kicked off in late January, nearing its March 13 deadline, researchers are already planning to conduct a similar, nationwide challenge.

AEDs can save the lives of those suffering cardiac arrests via electric shocks, particularly if used in the first minutes following the onset of the attack. … Read more
