REPEAT Is the public interested in science? The signs aren't encouraging. The Hubble Telescope teeters on the edge of breakdown, and the public's response is lukewarm. Science coverage in the media continues to shrink like cheap cotton... and science superstars on TV or in the movies are as rare as lanthanum. As we consider why today's folk give science the big yawn, we'll talk to people whose job it is to bring lab findings to the public. Also, a new study traces to childhood our psychological aversion to science. Plus, Seth re-lives his childhood at the San Francisco Exploratorium. BONUS: sing along with Seth!

We've all descended from a common ancestor, but, as Homo sapiens, we no longer brachiate through trees and have long abandoned our stone tools for iPods. Evolution has shaped us into the big-brained, bipedal, text-messaging specimens we are today. But it didn't happened without a lot of pressure. We'll look at some of the forces that have driven human evolution - from the snake-phobia that sharpened our eyesight, to the anger-management that was a prerequisite for civilization.Also, how your Blackberry may be changing the brains of future generations. And, are we engineering our own successors through robotics?Guests: Lynne Isbell - anthropologist, University of California, Davis Timothy Taylor - archeologist, the University of Bradford in the U.K. Nicholas Wade - science writer, New York Times, author of Before the Dawn: Recovering the Lost History of Our Ancestors Lee Gutkind - author of Almost Human: Making Robots Think

From hovercrafts to the quartz crania of aliens; find out what scientific concepts in the latest bullwhip adventure are more than a little nutty. Plus, the real crystal skulls, and the man who discovered that two of the most famous are fakes. Also, an incentive to tackle that to-do list: the 2012 Mayan apocalypse.

What happens when particles collide? The answer may tell us the dark secrets of the cosmos. At least, that's the hope for the Large Hadron Collider, the world's largest particle accelerator. When it fires up this summer, colliding protons may produce the elusive Higgs Boson - the so-called God particle - and reveal the building blocks of the universe. We talk to the Director of CERN, home of this massive device, about what happens when they throw the big switch. Also, what if black holes happen? Find out how these weird gravity pits are created, and whether they're actually two-way streets that allow information to escape after all. Also, plans are already underway for the next particle accelerator, and playing with fire: a new fusion reactor in France. Guests: Robert Aymar - Director General of CERN in Geneva, Switzerland Barry Barish - Physicist Emeritus, California Institute of Technology and Director of the International Linear Collider Global Design Effort Norbert Holtkamp - Principle Deputy Director General of ITER and physicist at the Spallation Neutron Source at Oak Ridge National Laboratory Simon Steel - Astronomer, Harvard-Smithsonian Center for Astrophysics

Forgot your own birthday? Misplaced your Shih Tzu? Did you put the milk in your backpack and the iPod in the fridge? Age may bring wisdom but - alas - not a boost in RAM. But there's hope - scientists are discovering that the brain is more malleable than thought. We'll hear about the science of neuroplasticity and what you can do to slow that cerebellum slide. Ever been to a brain gym? Plus, why the brains of London cabbies are bigger than those of your average commuter.

REPEAT Imagine if aging were a disease like measles, one that could be cured. Some scientists think it's possible and that we'll eventually halt - or at least slow - the march of time and extend lifespans into the triple digits and beyond. 100 could become the new 40, and 1000 the new 500! But that's a lot of years of filling out tax forms and showing up for dental hygiene appointments. Do we really want to live that long? If so, we should tap into the secret of longevity from Ming, a 400-year-old clam. Also, the surprising story of how aviator Charles Lindbergh helped develop a medical device that prolonged lives - all in support of the Nazi cause.

They can walk, roll, swim, and even dance to that funky music. Okay, so they're a little stiff on that one. But today's robots are not content to just sit and hum in a corner - they're movers and groovers, and not only on this planet. We'll go to the International Conference on Robotics and Automation and meet the latest in automatons - from aluminum chefs that whip up omelets to underwater machines that undulate like fish. Also, the robot challenge - building autonomous robots to scour the Red Planet. And, touchdown for the Phoenix Mars Lander.

How did the first cells make the scene? Could there be critters on some newly discovered planets? And what happens if we ever encounter weird life? These may not be the sort of questions you hear being bandied about in your local coffee shop, but they were hot topics at the AbSciCon conference held recently in Santa Clara, California, and sponsored by the SETI Institute. AbSciCon stands for Astrobiology Science Conference, and Seth was there, talking to researchers about progress in puzzling out how life began on Earth, and where it might have gained a claw-hold elsewhere. Could there be certain parts of our Galaxy that are off-limits for life? Also, hear whether our universe has special properties that render it just dandy for life, and whether we should be looking for viruses on Mars.

We all know how sex begins: a dimly-lit room, a come-hither smile, and a surfeit of parasol-shaded cocktails. But long before before all that, the gentle currents of the ancient sea floor set the mood.

We all struggle with our memories. This is as true for society as a whole as it is for an individual. In some cases, the effort to preserve cultural history is also a race against time. We'll hear how a cave in Norway is helping keep our seed heritage on ice. And, can you speak Tofa? Magat Ke? As languages disappear faster than the rain forest, one group is working hard to keep native voices heard.Meanwhile, how do we back up our written and pictorial heritage, most of which is on (ultimately perishable) paper? Not to mention the torrent of info in the form of Internet bits. That's the challenge at the Library of Congress, where a new digital initiative is trying to keep our intellectual inheritance intact. And IBM may soon help out in storing it all, as they develop magnetic beads that could increase the amount of memory on a chip by hundreds of times.Guests: Cary Fowler - Executive Director of the Global Crop Diversity Trust Stuart Parkin - Physicist at IBM's Almaden Research Center David Harrison - Director of Research for the Living Tongues Institute for Endangered Languages and author of When Languages Die: The Extinction of the World's Languages and the Erosion of Human Knowledge William LeFurgy - Digital Initiative Project, Library of Congress
