If you're not afraid to swallow your technology, you may want to check out new tech cleared by the Food and Drug Administration this week that lets you ingest a digital sensor powered by stomach acid that alerts your doctors about your health and your treatment habits.

The technology consists of a tiny, silicon-based sensor that, at 1mm wide (roughly the size of a grain of sand), can be consumed via pills and pharmaceuticals and pass through the body much like high-fiber food.

According to the developer, Proteus Digital Health, once the sensor is swallowed, stomach fluids that come into contact with it provide enough power to relay a signal that documents exactly when it was taken. This data is transmitted to a battery-powered patch worn on the skin that detects the signal and records the exact time the sensor was swallowed.… Read more

Developers eager to be among the first to create applications for Leap Motion's new gesture control system think it could be used to auto-translate sign language.

That was among the details the company released this morning about the initial round of requests from developers to design tools that work with the Leap -- technology that lets users control what's on their computers with hundredth of a millimeter accuracy with nothing more than their fingers or their hands.

The San Francisco company said that in the two months since pulling back the wraps on the Leap, more than 26,… Read more

First there was the Tower of Pisa, and now this. The ancient Colosseum of Rome, one of the most recognizable structures on the planet, is leaning. Italian authorities are investigating what steps to take in preserving the monument after it was discovered that the Roman structure is 40cm (15.7 inches) lower on its north side.

The slant was first noticed last year. La Sapienza University and the environmental geology institute IGAG have been asked by the Colosseum's preservation society to investigate the problem, according to Reuters.

Dr. Giorgio Monti, from La Sapienza's construction technology department, believes the … Read more

High electromagnetic field levels of household appliances (such as washing machines and hair dryers) and wireless devices (such as laptops and routers) may be at least partially to blame for the rise in childhood obesity in recent years, according to a 13-year study by Kaiser Permanente that followed hundreds of pregnant women and 733 of their children.

After controlling for several factors, including child gender, pre-pregnancy BMI, maternal age at delivery, race, education, breastfeeding, and smoking, researchers write in Nature's Scientific Reports that children exposed to high in-utero levels are nearly twice as likely to be overweight or obese … Read more

Radiation exposure is an occupational hazard for cardiologists performing a procedure called percutaneous coronary interventions (PCI -- better known as angioplasty), which helps restore blood flow to blocked arteries in patients with coronary artery disease. Lead aprons help, but they're not perfect, and they're heavy enough to take a toll.

Now a new system that employs robot-assisted stent and balloon placements to restore blood flow has received FDA clearance this week. Called CorPath 200, it allows cardiologists to work from inside a lead-lined cockpit, not only minimizing their radiation exposure but also improving their view of the angiography … Read more

Almost a year ago to the day, we wrote about a water-walking microrobot inspired by insects. Now the Jesus bug has ascended over the waves, as it were, at speeds up to 3.6 mph.

Qinmin Pan and colleagues from the Harbin Institute of Technology in China have redesigned their critter so that it jumps up and down like a real water strider, according to research published in ACS Applied Materials & Interfaces.

The team wanted to improve the Jesus bug-bot so that its legs would not break the surface of the water when leaping. … Read more

Though YouTube shouldn't exactly be your most trusted source of medical advice, in at least one case, videos on the site can help people manage a common form of vertigo without having to see a doctor, according to researchers from the American Academy of Neurology.

However, as is the case with pretty much any aggregator on the Internet (think Wikipedia), one should proceed with a healthy dose of caution, because just over half the videos are accurate -- which means, of course, that the others aren't.

The researchers who reviewed YouTube videos of the Epley maneuver, which can … Read more

MOUNTAIN VIEW, Calif. -- Google held the final round of its second annual international science fair on Monday morning, hosting 15 contestants from around the world between the ages of 13 and 18.

The science fair this year has grown considerably as not only did Google receive thousands of entries from more than 100 countries, but the program now also accepts entries in not just English but also 14 different languages.

Most of the projects derive from the United States, but there were also contestants present from India, Canada, Spain, the Ukraine, Swaziland, and Malta. Entrants are also judged in … Read more

All fat is not equal. Brown adipose tissue, more commonly called brown fat and abundant in both newborns and hibernating mammals, is the good fat, playing a prominent role in how quickly our bodies burn calories.

Brown fat also produces as much as 300 times more heat than any other tissue in the body, according to scientists at the University of Nottingham, so these scientists have developed a thermal imaging technique to measure not only a person's brown fat stores but also how much heat that fat produces.… Read more
