Researchers are testing a "bionic pancreas" pump that is inserted under the patient's skin. When paired with an app and a small chip, this device is capable of tracking blood sugar levels and adjusting the amount of insulin and glucagon (another hormone that controls blood sugar) on its own. A key study is slated for 2016 and the researchers, who are based at Boston University and Massachusetts General Hospital, plan to submit the device for US FDA approval in 2017.'
