A fundamental rule of nature is that nothing travels faster than the speed of light. Now, physicists working in Europe say they may have discovered a sub-atomic particle that breaks that speed limit. But that extraordinary claim is being greeted with a healthy dose of skepticism.
We all know too much sodium in our diet can be bad for our health. It can lead to high blood pressure, heart disease, strokes and more. The U.S. dietary guidelines made specific recommendations last year for African Americans to reduce their intake. But why is it so hard to cut back?
Speaker John Boehner didn't provide much reason Friday to hope that efforts to avert a federal government shutdown next week wouldn't go to the 11th hour like all congressional spending negotiations since last November's election.

NASA has updated its news on the pending descent of the Upper Atmosphere Research Satellite, and here's the headline: the satellite's re-entry has been pushed back. The UARS is now expected to plunge towards Earth late today or early Saturday, EDT.
The main drag on the satellite's speed - solar activity - is no longer the main reason why the spacecraft is slowing down. Its path, speed and spin are now so unpredictable that scientists say they cannot estimate when it will fall.
