Although compact fluorescent bulbs have helped scale back our energy use, consumers are wary of their mercury content. A Massachusetts-based company has come up with an energy efficient, LED bulb for household use that utilizes nanotechnology to make its light warmer and more attractive in color.

A group of researchers have recently examined the DNA from five African men, revealing over 1.3 million new genetic variations. Watch this videocast to understand the significance of these findings.

In this videocast, special guest Dr. John Ebel from the Weston Observatory of Boston College discusses the likelihood of a New England earthquake and the steps we've taken to prevent catastrophic damage.
