It's easy to take our electric lights for granted. Many people in developing counties don't have the luxury of electric grids and have to rely on kerosene lamps to brighten the night. Kerosene costs money and breathing the fumes is dangerous. A new light powered by gravity could be a superior solution to lighting needs.

GravityLight doesn't need to be recharged through solar cells. It doesn't use batteries at all. It's powered by the same force that keeps our feet on the ground. A weight attached to the light takes 3 seconds to lift up, but provides 30 minutes of light as it descends. … Read more

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

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

A Ph.D. student at the University of Toronto is using the same transfer paper currently affixing temporary tattoos to kids -- in conjunction with a common screen-printing technique -- to develop a medical sensor that keeps tabs on a person's exertion by monitoring the skin's pH levels.

Similar devices, which are called ion-selective electrodes (ISEs), are already common among athletic trainers and medical researchers to help spot fatigue, dehydration, or even metabolic diseases. But they tend to be bulky and don't stick well to sweaty skin.

The new sensor stays put and doesn't look so, … Read more

Next time you see an obese adolescent, blame the parents. At least that's what researchers at the Imperial College London are suggesting. They have developed a calculator to predict a newborn's chances of developing childhood or adolescent obesity

With only one in 10 cases of obesity being the result of a rare genetic mutation, researchers set out to determine which environmental factors played the largest roles in the development of childhood obesity.

"Once we compare different statistical models, and we added the genetic variants [associated with causing obesity], their ability to explain childhood obesity didn't improve … Read more

It's easy to pamper your pet with some table scraps, a few extra treats, and a little too much dog food. Before long, your fit Fido has become a hefty hound. Fujitsu is looking to help dog owners fight the fat with a pedometer and cloud service system.

The Wandant pedometer is based on motion-tracking technology from Fujitsu Laboratories. It measures and records the steps your pooch takes, picks up shivering motions, and monitors temperature changes.

All that data gets uploaded to an accompanying cloud service so you can view graphs and reports on your dog's activities.… Read more

About to fly halfway around the world? You could pop some melatonin in hopes of easing your inevitable jet lag. Or you could don a pair of odd-looking goggles and pretend you're modeling the Ikea line of Geordi La Forge eyewear.

Re-Timer, a lightweight wearable device invented to reset the body's internal clock, launched last week. It emits a soft green light onto the eyes to stimulate the part of the brain responsible for regulating the body's 24-hour clock.

Light received by photoreceptors in our peepers sends a signal to our brains telling us to wake up and smell the alertness. But circumstances including jet lag, irregular work shifts, and lack of sunlight during winter months can mess with the light we need to maintain a well-timed body clock and natural energy levels.

Enter the Re-Timer, which is meant as an alternative to sleep-assisting drug therapy. … Read more

Usually, iPhone docks are pretty interchangeable. A dock charges up your iPhone. Maybe it has some speakers. Maybe it has some other nifty feature that made you want to buy it. But the Lumawake iPhone dock has a whole bunch of nifty features to entice you.

Lumawake is designed as a bedside companion. It has an infrared motion sensor on it that watches you while you sleep, but not in a creepy way. Combined with an app, it tracks your sleep patterns and generates reports from the results.

The sleep-tracking ties in with a Smart Wake function. It determines when you're sleeping lightly near your wake-up time and slowly turns on LEDs to simulate sunrise. If that doesn't work to wake you up, a back-up alarm will sound to roust you from your bed.… Read more

If you're the type who looks away when you get stuck with a needle, you may long for the day when "Star Trek"-style medical devices will painlessly flood our veins with every kind of drug imaginable.

For some women undergoing in vitro fertilization, daily intramuscular injections of progesterone in oil (PiO) can be painful and stressful. Infertility is already immensely taxing for some -- researchers have shown it can generate levels of anxiety and depression on a par with those from cancer, heart disease, and HIV.

Progesterone helps carry the pregnancy to term, but sometimes must be injected up to 70 times. PiOna is a concept auto-injector from Cambridge Consultants that not only hides the icky thing from sight, but provides feedback about when the 1.5-inch needle is ready to use and guides the user through the process. … Read more
