Type 1 diabetes is at best a huge nuisance and at worst a constant threat of death for up to 3 million Americans whose pancreases don't produce insulin. Technology has improved the life of some diabetics, with insulin pumps replacing manual injections and glucose monitors that keep constant watch of diabetics' blood-sugar levels, reducing the need for finger-pricks. Yet diabetics are still required to frequently monitor and adjust their insulin levels. Now one company, Animas Corp., has completed the first successful human trial of a made-for-market artificial pancreas that takes care of everything automatically. Are we on the verge of relegating type 1 diabetes to an easily manageable condition? Here's a look at the quest to ease the lives of diabetics:

How did the HHM work in the field?
The artificial pancreas worked very well, but the trial only had 13 subjects, lasted about 20 hours, and took place under constant medical supervision at a hospital. The next step will be having patients use the HHM part-time in the hospital and part-time at home, then finally letting diabetics use it completely on their own. The artificial pancreas developed by the University of Virginia just started outpatient testing, and researchers expect the trials to ramp up and last through 2013.
Is an artificial pancreas a sure thing?
"Diabetics regularly receive glowing news about the latest and greatest leaps forward in insulin technology," and they're often disappointed, says Heather McClellan at The Escapist. This looks to be different, and an artificial pancreas is probably in the cards. That could be great — if diabetics are willing to entrust their lives to a machine that will "always carry the risk of mechanical failure or a snafu in the software."
So when might diabetics be able to use one?
An artificial pancreas is "still a long way off," says Meeri Kim at the Philadelphia Inquirer. How long? "I wish I could give you a time frame — two years, four years, a decade," says Animas chief medical officer Henry Anhalt. "Given the regulatory hurdles, we are moving as quickly as possible." Even when the pancreas does hit the market, it won't be cheap: An Animas insulin pump alone costs $6,343, for example. Still, many insurers will probably pick up the tab. If science pulls this off, diabetics will not only live better and healthier, but potentially eat normally, too, says Andrew Tarantola at Gizmodo. In other words, we will essentially "solve type 1 diabetes."
