David Pogue, a tech writer for the New York Times, reports on a new invention called the SimpleShot. The device provides an injection of glucagon, a hormone produced by the pancreas that stimulates an increase in blood sugar levels. Diabetics on insulin are often at risk for hypoglycemia, an abnormally low level of glucose in the blood. Normally administering the glucagon involves mixing a powder and a solution. The invention was a finalist in the Modern Marvels Invent NOW Challenge.
