Research offers promise for diabetics

Boston researchers have made a major step toward the development of an artificial pancreas that overcomes the bugaboo of most previous such attempts — dangerously low blood sugar caused by injection of too much insulin.

Their experimental device secretes two hormones normally produced by the pancreas — insulin and its counterbalancing hormone, called glucagon — and has been shown to control blood sugar levels in about a dozen people for at least 24 hours, they reported Wednesday.
