Artificial pancreas tells your tablet when you need insulin

As recently as the 1950s, one in three people diagnosed with Type 1 diabetes died within 25 years of diagnosis. People in the '50s had to monitor their glucose levels via urine testing and inject themselves with animal-derived insulin.

How far we've come. Today, researchers are working to develop an artificial pancreas for people with Type 1 diabetes that works with a smartphone or tablet to both monitors blood glucose levels and disperses insulin 24/7.

The goal, they say, is to reduce complications and improve the life expectancy of the millions of people with the metabolic disease -- because even though only 7 percent of them now die within 25 years of diagnosis, this rate is still far above general population mortality.… Read more

My life with the BodyMedia Fit activity tracker

Time to assess the last of the four activity trackers I've been living with for over two months, the BodyMedia Fit.

If you're serious about tracking every calorie burned as accurately as possible, this makes the other trackers look like toys. But it's also the least comfortable to wear, and monthly subscription fees may also put some off.

BodyMedia sells two versions of the Fit. The "Core" version for $120 lacks Bluetooth and so can't talk directly to apps on your iPhone or Android device. The "Link" version sells for $150 and … Read more

New nanoneedle technique probes inner workings of human skin

How does our top layer of skin -- the thin stratum corneum -- manage to keep water inside our bodies and microbes out, all while maintaining strength and elasticity, at just a fraction of the thickness of a sheet of paper?

In the first tests of its kind, scientists at the University of Bath are using a tiny "microneedle" with atomic force microscopy to probe the surface of the top layer of human skin and solve some of these mysteries.

Until now, researchers were able to use this form of microscopy only to analyze the surface of corneocytes, the cells that form the outer layer of the epidermis. Now, by adding a nanoneedle to the end of the probe, they can delve below the surface and shine a light on the cell structure within.… Read more

Video gamers outperform nongamers in vision test

Ladies and gentlemen, may I now present your deep thought of the day: People who play video games are better at playing video games than people who don't play video games.

OK, new findings out of Duke may be a bit more complex than that, but there's not much of a spoiler alert to this one. Hours spent at a gaming console seem to translate directly to a test, taken at a computer, of how the brain tracks visual stimuli, according to a new study at the Duke School of Medicine.… Read more

Chemists developing breathalyzer to detect and monitor diabetes

Nowadays breathalyzers are being used to detect far more than just how much alcohol one has imbibed. Researchers in Sweden are working on one that can spot marijuana and cocaine. Scientists in Germany are exploring one that can sniff out heart failure. And researchers in the U.S. are hard at work on one that can detect diseases such as diabetes.

And now, a group of chemists at the University of Pittsburgh is unveiling new sensor technology that could lead to a breathalyzer for not just the detection of diabetes, but the ongoing monitoring of it as well.… Read more

Poll: Would you go full cyborg?

It's only a matter of time, really. Google Glass, Epson's Movierio, the Oculus Rift, and similar technologies are at the cutting edge of wearable technologies. Sci-fi has certainly given us a glimpse at the potential future: internal links to the Internet, augmented eyesight and hearing, perhaps even full cybernetic bodies to house our minds.

We'll have the technology, we will build it. The question is, presuming it's safe, would you embed yourself with technology?… Read more

Segway-like robot helps fight fires with 3D, thermal imaging

In 2012, 83 firefighters died in the line of duty in the U.S. alone, and another 37 fatalities have been reported thus far in 2013. But, with better scouting tools, these numbers could be lowered.

Thank goodness for robots.

A new one out of the University of California, San Diego, may soon help first responders survey a fiery scene with its ability to enter a burning building and immediately transmit data on the state and location of the fire, the building's structural integrity, and the presence of any volatile gases -- all while on the lookout for survivors.… Read more

Mind-controlled quadcopter takes to the air

How close are we getting to actual brain control? It's starting to seem like it's not far off. On the sillier end of the spectrum, we've seen robotic ears and tails that respond to brainwaves, and more recently we've seen a brain interface for designing printable objects, a mind-controlled exoskeleton, and even mind-to-mind communication.

A team of researchers at the University of Minnesota has just added another exciting new technology to the list: a quadcopter that can perform feats of aerial agility, controlled entirely by the pilot's thoughts. … Read more

'Conscious Clothing' measures the junk you're breathing

Note to all you slightly obsessed folks out there who are into tracking your quantified self: isn't it about time you started keeping track of not just all the calories you inhale, but the air pollution as well?

The prototype for just such a device, dubbed Conscious Clothing, and the trio of designers who created it, were awarded $100,000 this week as part of an innovation challenge sponsored by (deep breath) the National Institutes of Health, the Office of the National Coordinator for Health Information Technology of the U.S. Department of Health and Human Services, and the U.S. Environmental Protection Agency.

The system is described as a "wearable breathing analysis tool" made up of sensors and strips of material wrapped around the chest to measure breathing volume. It calculates the particulate matter inhaled and transmits real-time data via Bluetooth, making it a perfect addition to any self data-tracking regime. … Read more

SmartVP videophone for deaf gets nationwide release

Let's face it: It doesn't matter how high quality the video is. Chatting over Skype or FaceTime doesn't do a lot of good if the call is between the hearing and the deaf and only the latter know sign language.

Now, following a successful release in California in April, the SmartVP videophone by Purple Communications is available free of charge to the deaf and hard-of-hearing nationwide, and it manages to solve the signing conundrum.… Read more
