We've been to the moon, we've mapped the continents, we've even been to the deepest point in the ocean -- twice. What's left for the next generation to explore? Biologist and explorer Nathan Wolfe suggests this answer: Almost everything. And we can start, he says, with the world of the unseeably small.

Lee Cronin: Making matter come alive

[LESS INFO] 197 VIEWS | ADDED 14:30:23 09/08/11
Before life existed on Earth, there was just matter, inorganic dead "stuff." How improbable is it that life arose? And -- could it use a different type of chemistry? Using an elegant definition of life (anything that can evolve), chemist Lee Cronin is exploring this question by attempting to create a fully inorganic cell using a "Lego kit" of inorganic molecules -- no carbon -- that can assemble, replicate and compete.

Rachel Pike: The science behind a climate headline
11/10/09

In 4 minutes, atmospheric chemist Rachel Pike provides a glimpse of the massive scientific effort behind the bold headlines on climate change, with her team -- one of thousands who contributed -- taking a risky flight over the rainforest in pursuit of data on a key molecule.
