Scientists have successfully tested a bionic pancreas on 20 adults and 32 teenagers with Type 1 diabetes for five days, reports the Associated Press. The pancreas is a wearable device that continuously monitors a patients blood sugar levels and administers insulin automatically, when needed. And, unlike other wearables currently in the works, this one was able to correct low blood sugar levels, as well as high. These results were presented at the American Diabetes Association conference in San Francisco on Sunday, and the study was published in The New England Journal of Medicine.
