Blood glucose monitors are growing up, and it's about time. With some 26 million diabetics in the U.S. alone, (that's almost 1 in 10 Americans), and hundreds of millions globally, according to the American Diabetes Association, glucose monitoring has become one of the largest patient-generated data sets in the world -- and yet much of that data is being uploaded manually onto desktops or written by hand into little log books.
Using two high-tech imaging techniques custom-built for their field, researchers at Massachusetts General Hospital and Harvard Medical School will unveil a new method for examining tumor growth at theFrontiers in Optics annual meeting in Orlando, Fla., in October.
Multiphoton laser-scanning microscopy (MPLSM) and optical frequency domain imaging (OFDI) combine to give scientists the ability to look deeply inside tumors in real time, revealing extremely detailed pictures of live tumors as they grow. MPLSM is an advanced fluorescence-imaging technology, and OFDI captures tissues using their light-scattering properties.
Unfortunately, the method that creates what the researchers call "astonishing" images … Read more

Also, get excited about the Ubi Interactive, which turns any surface into a touch screen. All that and much more on this week's Crave show. … Read more
When surgeons thread a catheter through a vein to the heart -- a procedure called cardiac ablation -- they are relying on electrodes at the catheter's tip to listen to the heart's electrical activity and find the source of -- and hopefully fix -- any heartbeat irregularities.
Now, a new system called the Rhythmia Mapping System, recently bought by Boston Scientific, translates that activity into a 3D map of the heart as it pumps blood. The system received FDA 510(k) clearance in the U.S., only months after receiving the similar CE Mark of approval in Europe.… Read more
For the first time in the U.S., surgeons have successfully transplanted a bioengineered blood vessel into the arm of a patient -- a possible stepping stone toward more complex human-engineered organs such as livers or eyes, and potentially a more immediate boon for kidney dialysis patients and perhaps even people with heart disease.
The surgery represents a major milestone for tissue engineering: The bioengineered blood vessel can be stored relatively easily and donated universally (unlike veins harvested from a patient's own body and therefore specific to that body). Also, it's human-cell-based, with no biological properties that can cause organ rejection.
"We hope this sets the groundwork for how these things can be grown, how they can incorporate into the host, and how they can avoid being rejected immunologically," Jeffrey H. Lawson, a vascular surgeon and biologist at Duke Medicine who helped develop the technology and performed the implantation, said in a statement. "A blood vessel is really an organ -- it's complex tissue. We start with this, and one day we may be able to engineer a liver or a kidney or an eye."… Read more
For diabetics who have to constantly manage their blood-sugar levels, insulin works. The problem is, many people with Type 1 diabetes have to prick their fingers multiple times a day to monitor their levels, and inject themselves with insulin when those levels are too high. And they don't always administer the right amount at the right time.
Researchers at the Massachusetts Institute of Technology and Boston Children's Hospital hope to automate insulin delivery with a novel nanotech approach that involves injecting a gel that detects blood-sugar levels and secretes insulin when needed -- with a single injection doing do the trick for as many as 10 days.… Read more

With a name like Blood & Glory you probably are not expecting a family-oriented casual game. And you'd be right. If you've enjoyed the TV series Spartacus, then Blood & Glory will appeal to you. It's based around gladiatorial combat in which you battle in the arena to the death, all for the glory and adulation of the crowds. Blood & Glory installs quickly.
Graphically, Blood & Glory is a treat. The graphics are well done, but a warning that there is a huge amount of blood (hence the name!) would be tame. This is probably the … Read more
Now that you have your iPhone 5, you've probably noticed that not all apps take advantage of the wider screen. I've been noticing that the updates have been pouring in fairly quickly, but unfortunately, I still have a lot of pillarboxed apps and games that show black spaces on each side.
For this week's collection I put together three games that look absolutely fantastic on the iPhone 5's larger display. The first is the latest in a popular arcade-style racing franchise and gives you more viewing area as you blaze around the track. The second is an action RPG that pits you against demonic beasts as you hack and slash your way to saving a kidnapped queen. The last is the newest version of a popular soccer series that might be the best sports game available on iOS.… Read more
While Blood & Glory: Legend resembles Infinity Blade in some respects, its well-designed user interface and great graphics and storyline enhance the overall user experience. Given the fact that it is free, anyone who liked the app's predecessor, Blood & Glory, will surely enjoy the enhanced game. Still, we found that the game doesn't quite differ enough from the previous version.
We like games that have a story, and the developers of Legend have given users a reason to kill all those monster competitors besides staying alive. The game has a central figure, Crimson, who has to pass … Read more
