Special Collection: NOVA scienceNOW on Teachers' Domain

From the award-winning producers of NOVA comes NOVA scienceNOW, the fast-paced, innovative, and entertaining science program featuring timely science and technology stories along with biographical profiles of intriguing science personalities on the cutting edge of their fields. The program is hosted by Neil deGrasse Tyson, well-known astrophysicist and author, described by TIME magazine as “the Carl Sagan of the 21st century”. Also check out The Secret Life of Scientists , NOVA’s web-exclusive series that highlights two science stars every month through a selection of short, punchy films where you see what happens when the lab coats come off.
