Researchers Find Hormone That Grows Insulin-Producing Cells

Thursday, April 25, 2013

When researchers turned on a gene for the hormone in the livers of diabetic lab mice, the number of insulin-making cells in their pancreas glands tripled within 10 days. Although the research was conducted in animals, the scientists say the findings could be relevant for humans.


With Bird Flu, 'Right Now, Anything Is Possible'

Friday, April 19, 2013

These days hospitals drill for mass casualty disasters like the explosions at Monday's Boston Marathon. But when it happened for real, the first response was disbelief. Then the victims began arriving. Doctors say they were confronted with the kinds of IED injuries that U.S. troops have gotten in Iraq and Afghanistan.


Scientists Race To Stay Ahead Of New Bird Flu Virus

Sunday, April 14, 2013
