EVOLUTION:

NOVA: Evolution in Action - The California Terrestrial Salamander

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.

NOVA: Hunting the Elements

Where do nature’s building blocks, called the elements, come from? They’re the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. To unlock their secrets, David Pogue, technology columnist and lively host of NOVA’s popular "Making Stuff" series, spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe’s most abundant elements, and the rarest of the rare—substances cooked up in atom smashers that flicker into existence for only fractions of a second.
