Life on Mars; Francis Ford Coppola; Dominique Browning

A consideration of the existence of extraterrestrial life--after the discovery of microbes on the small fossil remains of a Mars meteorite--with Dr. Neil deGrasse Tyson, Dr. Lionel Tiger, and Dr. Richard Berendzen. Francis Ford Coppola on his new film, "Jack," about a ten-year-old boy whose cells are growing at a rate of four times the normal rate, causing him to look like a 40-year-old man. Dominique Browning, editor of Condé Nast House & Garden, talks about the new name and look of the magazine, two years after its protested discontinuation.
