Ansar al-Sharia is one of the most powerful Islamist militias in eastern Libya. The brigade claims hundreds of men who fought, with U.S. and NATO support, to unseat strongman Moammar Gadhafi last year.

The Libyans have a different view. They say it was a premeditated strike, launched by foreign fighters with ties to al-Qaida.

An experimental drug that helps people who have Fragile X syndrome is raising hopes of a treatment for autism.

The drug, called arbaclofen, made people with Fragile X less likely to avoid social interactions, according to a study in Science Translational Medicine. Researchers suspect it might do the same for people with autism.

Nearly 13 million Americans have gotten, or will soon be getting, rebates from their health insurance companies. This is because of a provision in the Affordable Care Act (aka Obamacare) that's supposed to force insurance companies to run better.
