This week, the Science Weekly team discuss solar power, light conversion and clean power as we hear from Dan Nocera, the MIT professor who believes chemistry can solve the energy crisis. If you're interested in more of what he has to say, his full half-hour conversation is this week's Science Extra podcast. Oh, and if you want to admire his beard, head here.
Also in the show, Alok Jha tells us why scientists are calling for greater investment in carbon capture technologies. Ian Sample gives the lowdown on Nasa's new giant Glast telescope and tells us why it's now safe to go back in the water. Meanwhile, Nell Boase ponders extreme gardening and describes the oldest viable seed in the world.
Finally, Leonard Mlodinow, theoretical physicist at the California Institute of Technology and author of The Drunkard's Walk, explains how randomness rules our lives.
