Vomiting Larry robot upchucks for science

Norovirus is a particularly nasty virus that causes severe gastrointestinal upset. It's famous for turning cruises into nightmares. It's a tough little number that spreads easily and is hard to kill. To study it, you can't just ask a bunch of sick people to pop down to the lab and vomit on demand. That's where a robot nicknamed Vomiting Larry comes in.

Larry is a one-robot upchucking machine in residence at the Health & Safety Laboratory in Buxton, U.K. He's an anatomically correct model and his favorite hobby is barfing for science. He helps scientists determine how far the norovirus can spread. … Read more

'Dystextia': Muddled texts can signal stroke, doctors say

Most of us have sent a garbled text or two (or dozens) in our day, and probably received more than our share as well. But such disoriented messages can in some rare cases move beyond the parlance of speedy modern-day communication to signal a health emergency, Harvard scientists caution.

In a study published online in the Archives of Neurology last week, the researchers coin the term "dystexia" to describe a confused text message that may indicate neurological dysfunction.

They cite the case of a 25-year-old pregnant woman who sent her husband a series of confusing messages about their baby's due date following a routine doctor's appointment. … Read more

Magic-forest LED walls calm kids on way to surgery

Anyone who's had surgery would probably agree that being wheeled into the operating room can prove quite the anxiety-producing ride.

A London design studio has come up with a wonderfully creative way to calm young patients en route to surgery -- interactive wallpaper that turns clinical corridor walls into a magical forest to engage and distract the kids as they journey toward their procedure.

The installation, called Nature Trail, fills about 165 feet of corridor walls in part of the Mittal Children's Medical Centre at London's Great Ormond Street Hospital. … Read more

Brain implants let paralyzed woman move robot arm

Jan Scheuermann can't use her limbs to feed herself, but she's pretty good at grabbing a chocolate bar with her robot arm.

She's become the first to demonstrate that people with a long history of quadriplegia can successfully manipulate a mind-controlled robot arm with seven axes of movement. Earlier experiments had shown that robot arms work with brain implants.

Scheuerman was struck by spinocerebellar degeneration in 1996. A study on the brain-computer interface (BCI) linking Scheuermann to her prosthetic was published online in this month's issue of medical journal The Lancet.

Training on the BCI allowed her to move an arm and manipulate objects for the first time in nine years, surprising researchers.

It took her less than a year to be able to seize a chocolate bar with the arm, after which she declared, "One small nibble for a woman, one giant bite for BCI." Check it out in the video below. … Read more

IBM imagines a computer that smells your illness

For the past several years, IBM's research arm has been making predictions about emerging technologies that will change our lives over the next five years. Dubbed "5 in 5," the annual year-end list has already accurately predicted the rise of now-familiar cultural touchstones like Siri, as well as our reliance on smartphones for everything, and real-time speech translation.

This year, IBM has taken a more in-your-face approach to predicting the future of innovation, by specifically focusing on, well, the face and the five senses that make their home there (and yes, hands and everywhere else in the case of touch).… Read more

Smart motorcyle helmet cushions you from concussion

Styrofoam, a plastic shell, and your own head are the only things separating your brain from the curb if you have an accident. It's a standard setup that most helmet designers use, but that arguably doesn't go far enough, as concussions are still one of the most common injuries bikers suffer in an accident.

What differentiates 6D Helmets' new products are the dual layers designed to protect a rider's head from a broader range of impact than standard helmets -- in particular, low-threshold energy impacts. A standard helmet is certainly useful in high-speed collisions, but 6D's "Omni-Directional Suspension System," or ODS, aims to keep motocross bikers safer in accidents involving less than 10mph of force. … Read more

Sensor system gives disabled kids a second shot at tablets

For some people, touching a touch screen is difficult, if not impossible.

According to Georgia Tech, more than 200,000 kids in the U.S. public school system have some sort of orthopedic disability that hinders them from experiencing the vast information that awaits them on a tablet or smartphone. Children with neurological disorders -- such as muscular dystrophy, cerebral palsy, and spina bifida -- can also have difficulty using touch-screen devices due to motor skill impairments.

The need to counteract this limitation inspired Ayanna Howard, a Georgia Tech engineering professor, and graduate student Hae Won Park to create Access4Kids, a prototype assistive device that could level the playing field.… Read more

Violent video games and aggression: A cumulative effect?

Video games are the subject of so many studies, not to mention findings. Some suggest cognitive benefits, others behavioral issues that may or may not persist over time.

Many of these studies are small enough to require further investigation, and the journalists reporting on them often confuse correlation (when results happen in tandem) with causation (when one action is shown to result from another).

A new study out of Ohio State University suffers from a small sample size (70 participants), but its findings -- that people who play violent video games for three consecutive days show increases in aggression and hostilityRead more

Bleeding internally? Seal it with this DARPA foam

While any soldier dreads the idea of being shot, sustaining an internal abdominal injury from an explosion or other impact can be far worse. Bleeding from wounds that can't be compressed causes some 85 percent of preventible battlefield deaths.

As part of DARPA's Wound Stasis program, Arsenal Medical has developed an injectable polymer foam that expands inside the body to stanch internal bleeding.

The concept of foam growing in the body reminds me of that 1980s B-horror film "The Stuff," but apparently it's effective.

Based on testing in pigs, DARPA says the product can control hemorrhaging in an abdominal cavity for at least an hour, a critical window to get the soldier to a medical facility. … Read more

Microsoft gives $75,000 to team building cloud-based stethoscope

Pneumonia, which claims the lives of more than 1.2 million children under the age of 5 every year, is the leading cause of death in children worldwide, according to the World Health Organization. And in certain regions, such as South Asia and sub-Saharan Africa, pneumonia alone accounts for 85 percent of pediatric deaths.

So it comes as little surprise that Microsoft, through its Imagine Cup Grants program, has awarded its second-place prize of $75,000 to a team out of Australia that is developing a tool to diagnose the infection quickly and affordably. (The first-place prize went to a … Read more
