New York Knicks guard and Harvard University alumnus Jeremy Lin may be a sudden NBA sensation, but the men's basketball team at his alma mater is making its own mark on the national scene.

Harvard is currently on top of the Ivy League basketball standings. And with a 21-3 overall record and some impressive nonconference wins, the Crimson spent part of the season in the Top 25 in national polls for Division I.

Federal regulators signed off on the construction and operation of two nuclear reactors at a Georgia plant. It's the first license to be granted for a new reactor in the U.S. since 1978. Nuclear expert Per Peterson discusses the reactors' design, safety features and what this means for the future of nuclear power.

In his book Concrete Planet, author Robert Courland discusses why the concrete first used by the Romans is more durable than the concrete used in most present day buildings. Plus, mineralogist Peter Stemmerman tells us about his invention, Celitement and why it is greener than Portland cement.
