I am Type 1 Diabetic. I have done some research, but am by no means an expert.

1. Yes 2. No. "Melton said that the device Anderson and his colleagues at Massachusetts Institute of Technology are testing has thus far protected beta cells implanted in mice from immune attack for many months. “They are still producing insulin,” Melton said."

There are two breakthroughs. The mass production AND the ability of the device to protect the cells from destruction.

3. Yes. It reacts ideally in pretty much all scenarios. When you eat, it produces insulin. When you fast, it doesn't lower you into hypoglycemia. When you're sick (like a cold) it regulates insulin as it should, as your body needs more or less as your insulin sensitivity is off.

This is definitely HUGE!
