Republicans on the House Oversight Committee want to hear why the State Department repeatedly denied requests for tighter security for U.S. diplomats in Libya before the deadly September 11th attack on the consulate in Benghazi. The State Department has been tight lipped on the issue.

Americans Robert Lefkowitz and Brian Kobilka have won the 2012 Nobel Prize in chemistry. The Royal Swedish Academy of Sciences cited the two researchers Wednesday "for studies of G-protein-coupled receptors."

For the past decade, scientists have been toying with the notion of encapsulating medicine in microscopic balls.

These so-called nanospheres could travel inside the body to hard-to-reach places, like the brain or the inside of a tumor. One problem researchers face is how to build these nanospheres, because you'd have to make them out of even smaller nanoparticles.

The U.S. Supreme Court returns on Wednesday to the emotional issue of affirmative action in higher education. The court will once again hear oral arguments on the issue, this time in a case from the University of Texas.

Over the past 35 years, the court has twice ruled that race may be one of many factors in determining college admissions, as long as there are no racial quotas. Now, just nine years after its last decision, the justices seem poised to outright reverse or cut back on the previous rulings.

My first protocol on rooting in sports is that you should stick with the teams that you grew up with. I know we're a transient society, but that's just it: Continuing to cheer for your original hometown teams is one way of displaying the old-fashioned value of allegiance.

If you grew up in Cleveland, say, and moved somewhere Sun Belt-ish, I know how hard it is, but the measure of whether you are a good person is that you must remain loyal to the Browns and Indians and that team that LeBron James left behind.

You wouldn't be surprised to learn that a laboratory run by the U.S. Department of Commerce is working on more precise methods to measure stuff.

However, you might not expect it to be at the cutting edge of the mind-bending world of quantum physics. But on Tuesday, David Wineland became the fourth employee at the National Institute for Standards and Technology, a federal lab, to win a Nobel since 1997. Wineland learned he will share the Nobel Prize in physics with Frenchman Serge Haroche for work that's both esoteric and practical.

The U.S. government filed a lawsuit against Wells Fargo & Co., today, saying the bank was reckless when it issued federally guaranteed mortgages.
