Move over Evian. While filming "Ice Age Death Trap," the excavation team had some fun and quenched their thirst in an unusual way—by drinking water trapped in ancient mastodon and bison bones. What did they name their new beverage? Mastodon juice, of course!

Vincent van Gogh has inspired several talented artists to turn their hands to forgery. Can computers be used to identify which works are really his? To find out, NOVA scienceNOW, working in cooperation with the Van Gogh Museum in Amsterdam, commissioned an expert in art reconstruction to make a meticulous copy of a van Gogh painting. Then, we challenged three different computer teams—from Princeton, Penn State, and Maastricht universities—to see if they could spot the imitation in a group that included five genuine van Goghs.

NOVA visits David Wake, a renowned evolutionary biologist at the University of California, Berkeley, as he explains why members of the same species of California salamander look and behave so differently. It's a case study of Darwin's theory of evolution by natural selection, and an example, Wake says, that Darwin himself would have loved.
