TOKYO--Downed a few too many beers this holiday season? No problem. Just tuck your organ into this electronic diaper for men and you won't have to get out of bed to visit the loo.
If researchers at the University of Illinois have their say, bandages are about to get a whole lot cooler.
A team of engineers has created a bandage that in just one week not only encourages new blood vessel growth but helps guide that growth as well.
"The ability to pattern functional blood vessels at this scale in living tissue has not been demonstrated before," co-principal investigator and electrical and computing engineering professor Rashid Bashir says in a school news release.
It's often the case that a device or substance with a known benefit also comes with known risks--typically referred to as side effects and listed quickly at the ends of commercials. So it seems worth noting when a product's side effect may in fact be useful.
The Valkee, a portable headset launched in August of 2010, directs 8- to 12-minute doses of bright light through the ear canal and into the brain to improve seasonal affective disorder. It turns out that this concentration of bright light into the brain may also improve motoric reaction time, according to a study conducted by Verve Research in Finland.
The placebo-controlled study (meaning some were given the treatment and others a placebo in its place) tested the effects of the Valkee headset on Finnish national league ice hockey players and found that those exposed to 12 minutes of light via the headset sped up their already fast reaction times by 20 percent.
"The placebo-controlled study showed a significant improvement in motoric reaction times of top athletes using bright light via the ear canal," says lead researcher Mikko Tulppo in a news release.… Read more
Patches of tiny needles have already been shown to effectively deliver medications painlessly, and without a bloody mess. Now the tiny needles could also be used to monitor body chemistry in real time.
The new tech, developed by a team of biomedical engineers out of North Carolina State University, the University of California at San Diego, and Sandia National Laboratories, employs electrochemical sensors in the hollow channels of microneedles to detect certain molecules. The researchers reported their findings in the chemistry journal Talanta.
Current body chemistry monitoring involves taking samples, often before or after an event. Wearable micro-sensors, on the … Read more
The spray seen 'round the world at the UC Davis "Occupy" protest inspired one of the more awesome memes of the year, but just how dangerous is that police-grade pepper spray?
The infographic team at Online Criminal Justice Degree seized on this moment to answer that question. Turns out the nasty orange spray is 1,000 times spicier than the common jalapeno, and more than twice as potent as the consumer pepper spray you might carry around with you.
Click on the excerpt below to see the full image and find out just how safe (or not) the stuff is, as well as what to do if you ever get sprayed yourself (hint: don't rub, and always carry milk and soap to all acts of civil disobedience).… Read more
All right, people, I hate to be the bearer of such grave news, but resolution season is almost upon us. If you're wondering how to make 2012 the year you finally shed those extra pounds, start choosing the apple over the fries, floss every day, etc., read on.
Mobile health technology continues to prove itself. The latest example comes in the form of on-the-go diabetes management.
In a recent small trial, 30 patients with type 2 diabetes spent 12 months using a smartphone app that provided real-time feedback on their blood-sugar levels, prompted them when to eat or take other action, and sent digital logbooks of their readings back to their doctors.
The surprising result: these patients had 58 percent fewer ER and hospital visits over the year of the study than they'd had the previous year.
It's important not to overinterpret that result. Not only … Read more
Traditionally, doctors and midwives have used a technique called pelvimetry to measure the pelvis and try to determine its adequacy for giving birth. But pelvis size is just one factor in how smoothly labor will go, rendering the method largely insufficient.
Scientists in France have been working to take some of the guesswork out of labor predictions. Today, at the Radiological Society of North America's annual meeting, they are presenting results of a study showing that their newly developed software, called Predibirth, predicts birth outcomes quite accurately.
The researchers used their software to process magnetic resonance images of 24 … Read more
A new report from Argentinian scientists states that electromagnetic radiation in a laptop's Wi-Fi connection could take the swagger out of sperm.
The thought-provoking article, published in the journal Fertility and Sterility, is the culmination of a study conducted by Conrado Avendano, a biochemist working for the Nascentis Center of Reproductive Medicine in Cordoba, Argentina, in conjunction with a group of medical professionals.
The study found that semen from 29 donors placed for four hours in room-temperature petri dishes 3 centimeters from a laptop actively connected to Wi-Fi showed "a significant decrease in progressive sperm motility and an … Read more
Let's face it. Some things are just plain easier for kids today. Want to ask someone to the school dance without feeling so awkward? Just use your thumbs. Need to do research for a school paper? Just pick your search engine.
But perhaps my biggest tech envy to date can be found in the newly FDA-cleared AcceleDent system, a device that, when worn just 20 minutes a day, can dramatically speed up orthodontic tooth movement.
Traditionally, dental braces reshape the positioning of one's teeth by applying force to them. The AcceleDent device, worn with braces, simply speeds up tooth movement by vibrating them 20 minutes a day. (Insert inappropriate middle school joke here.)… Read more
