Want to get off the grid but think it’s just too expensive? UCB's Dr. Jeff Grossman explains how nanotechnology may be used to make solar panels cheaper. We’ll also hear from philosopher Patrick Lin of the Nanoethics Group about ethical dilemmas that crop up when we try to improve our lives through nanotechnology.

The two Mars Rovers are alive and well after surviving their second Martian winter. Come and see photos of discoveries they made during their third year on Mars, with Exploratorium Senior Scientist Paul Doherty.

The South Pole Telescope captured its first light on Feb. 16, 2007! Join Exploratorium host Mary Miller as she talks with scientists at the South Pole and finds out more about life at the Pole.

Julia Moore and Evan Michelson of the Woodrow Wilson International Center for Scholars talk about nanotechnology products they’ve found for sale in a variety of stores. Should these products have some sort of special label? Journalist Philip Ball also weighs in on the controversy.

Join Exploratorium biologist Karen Kalumuck as she leads a Darwin 101 Webcast using hands-on explorations, audience participation, and special surprises—just in time to celebrate his birthday!

Dr. Jim Tour, a chemist at Rice University, builds the world’s smallest vehicles. He calls them “nanocars,” and he thinks these tiny vehicles might lead to nano-sized factories. We’ll also hear from University of Florida graduate student Diane Hickey, who will tell us some of the interesting reactions she’s run into when explaining nanotechnology.

Join us as we speak with IBM Fellow Dr. Don Eigler, who first used a scanning tunneling microscope to demonstrate the ability to build structures at the atomic level by spelling “I-B-M” with individual atoms. Also, meet Tom Rockwell, Director of Public Exhibition at the Exploratorium, who describes, in an audio essay, how he imagines the land of the very small.

Mary Miller chats with scientists at the South Pole about the nearly-completed telescope. The satellite connection to the pole deteriorated quickly, and we hope to repeat this program in the near future. Stay tuned for updates!

Dr. Stephen H. Schneider joins us to discuss climate change. Dr. Schneider was honored in 1992 with a MacArthur Fellowship for his ability to integrate and interpret the results of global climate research through public lectures, seminars, classroom teaching, and research collaboration with colleagues.

Join us as we talk to South Pole scientists about Ice Cube, a major new telescope being built deep below the surface to detect ghostly neutrino particles. The neutrino telescope will use thousands of detectors spread over a square kilometer of ice below the South Pole to study cosmological mysteries such as black holes, gamma ray bursts, and the remnants of supernova explosions.
