           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.
	
	Guests:

      
          Diana Valencia - Planetary physicist at Harvard University
	  Charley Lineweaver - Cosmologist at the Australian National University
	  David Deamer - Research scientist at the University of California at Santa Cruz
	  Baruch Blumberg - Scientist at the Fox Chase Cancer Institute, Nobel Prize winner, and Trustee at the SETI Institute
	  Matthew Kenworthy - Astronomer at the University of Arizona
	  Eric Korpela - Research scientist at the University of California, Berkeley

           Maybe Dr. Doolittle was on to something; animals are smarter than we think.  Birds, apes, and dolphins are all clever problem solvers with a rich vocabularly and - in some cases - self-awareness. Find out what you can learn from our furry, finned and feathered friends. Also, why you are so much an animal yourself, all the way down to the bare bones.
	  Plus, enter the locked vaults that hold extinct and newly-discovered animal species.  And why B-movie critters steal the show.
	
	A new species? This is a grey-faced sengi.

           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. It was there, 570 million years ago, that two ropy sea creatures found each other and changed the course of evolution.Hear how sex began and where it's headed: if you think your love life is mechanical now, just wait until you're cozying up to titanium skin and the latest emotion software.Plus, everything you always wanted to know about modern sex research, but were afraid to ask.Guests:

           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:

           There are two kinds of people: those who are unstylish, socially inept, yet academically gifted, and those who tease them.  Being a nerd is rough; it's no fun to sit alone in the cafeteria or be forced to dine on beach sandwiches.  But revenge is sweet: the world depends more than ever on the witty and gifted to keep it technologically and scientifically turning.  So who gets the last laugh?  Just ask Bill Gates.  Then again, have attitudes towards eggheads really matured?  Just ask Al Gore.Hear why America has contempt for nerds, while other countries treat them as rock stars.  Also, how to solve a Rubik's Cube in seconds, and a Geeksta Rap sing-along.Guests:

You may feel strongly about these things - even swear by them; but that doesn't make them true, only that your neurochemistry is in high gear.We'll hear how chemicals in the brain conspire to produce certainty and why even death and taxes are not foregone conclusions.

           Like your stomach subjected to repeated $1.99 buffets, the universe is ever-expanding.  As it grows, it inexorably becomes more chaotic.  We'll hear what drives this increase in entropy, and whether there can be meaning in a universe that will ultimately become no more than a dark soup of cold particles.Also, the surprising patterns of organization around us - find out why you behave with the mathematical logic of an atom and why you can't outwit the crowds at your favorite bar.  Also, happy 300th birthday to Carl Linneaus.  Without him, you and your neighbors wouldn't be in the members-only club Homo sapiens.Guests:
      David Quammen  -  award-winning science, nature, and travel writer.  His article about botanist Carl Linneaus, "A Passion for Order," appears in the June 2007 issue of National Geographic magazine
      Lawrence Krauss - physicist and cosmologist, Case Western Reserve University

           When it comes to contacting ET, SETI scientists do the math.  They've been filling in values for the Drake Equation ever since 1961.  That's when Frank Drake proposed his simple formula for estimating the number of communicating civilizations in the galaxy.  It's one equation that everyone can understand.We'll talk about the current best estimates for the terms in Drake's famous formulation - from the number of Earth-size planets to the life expectancy of advanced civilizations.   Also, with all this number crunching, why haven't we yet heard from ET?Guests:

           Leonardo da Vinci is considered a genius for combining art and science.   But how usual is this for us mere mortals?  Can science and art sucessfully inform each other?We'll hear how the insights of French writer Marcel Proust anticipated modern neuroscience. Also, a debate over the evolutionary function of art.  Does it have survival value?  We meet a robot whose painting talents have garnered it a job in one of America's top museums.  And, hear - or don't hear - why some of our relatives don't monkey around with music.Guests:
                  Jonah Lehrer - science journalist, editor-at-large, Seed magazine and author of Proust Was a Neuroscientist
		  David Sloan Wilson - evolutionary biologist at Binghamton University, and author of Evolution for Everyone: How Darwin's Theory Can Change the Way We Think About Our Lives
		  Ellen Dissanayake - independent scholar and author of Art and Intimacy: How the Arts Began
		  Leonel Moura - conceptual artist
             Find out more about RAP, including a picture,  at the American Museum of Natural History website!Whip up some madeleines (click here for a  recipe) and savor your own remembrance of things past.

           Here's a time-saver:  ditch that car and find your local wormhole.  You'll be transported from your front door to Pilates - or to a piazza in Rome, if you prefer - faster than you can say "instant messaging."We'll get reaction from a physicist and science-fiction fans to the movie "Jumper," that explores the idea of teleportation, and find out whether a wormhole commute is really possible.Also, futuristic modes of transportation that have yet to crowd the skies: jet packs and  flying cars.  Whatever happened to them?  And, what travel will be like in the year 2050.Guests:

           Do you find eating tiresome?  Is taking time to chew taking too big a bite out of your productivity?  Well, you can soon say goodbye to the burden of beefy burgers and chlorophyll-ridden lettuce - you'll be able to pop a pill for all your nutritional needs!   As much as you may find this too much to swallow, what we call "food" is changing.  Indeed, you might not recognize the dinner of the future if it landed on your plate today.In this hour, a look at high and low-tech visions of dinner time... whether E.T. would ever get a hankering to snack on Homo sapiens...  what percentage of a Twinkie is mined... and growing meat in the lab.   Plus, food fights of the past and future.Guests:
      Steve Ettlinger - author of Twinkie Deconstructed: My Journey to Discover How the Ingredients Found in Processed Foods Are Grown, Mined (Yes, Mined), and Manipulated Into What America Eats
      Warren Belasco - Professor of American Studies at the University of Maryland, and author of Meals To Come

           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

           Don't worry if you've lost your senses - we've found them.  Find out why we've evolved taste, sight, hearing, touch, and smell the way we have, and why we don't sense our world through antennae or echolocation.  Discover what part of the tongue recognizes anchovies and why cats can't taste candy.  And, in need of some virtual surgery?  Visit the robotics lab where computers are wired with the sense of touch.Also, release yourself from the limits of your biology:  from bionic limbs to infrared vision; join humans of the future who are enhanced with super-senses.Now that you have a feel for the taste of this show by nosing about this blurb, you can see that it's worth a listen.   Make sense?Guests:
      Tom Finger - Cell and Developmental Biologist at University of Colorado Medical School and Co-Director of the Rocky Mountain Taste and Smell Center.

           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.Guests:

           Think you have it together?  Then, you'll want to thank the four fundamental forces of nature.  They hold the universe together, govern everything that happens, and generally make it what it is today.  Discover their universal properties and how they're in action all around us.  From the gravitational pull that with may cause an errant asteroid to wallop Mars, to the electromagnetic phenomena that make asteroid showers an impressive sight.   Also, physicist Freeman Dyson makes the case for spacecraft propelled by nuclear bombs.Plus - the four forces are governed by fundamental laws, but are these laws made to be broken?  Find out whether you could zip through space at faster than light speed.Guests:

           Some detectives don't look for fingerprints or interrogate suspects to unravel mysteries. Instead, they're dressed in white coats, and armed with DNA probes and star maps. These are the science detectives: researchers who have found innovative ways to use science to solve puzzles that no one else can.Find out how a biologist helped international police pinpoint elephant poaching in Africa. Also, astronomers who can decipher when and where Vincent van Gogh painted his famous nighttime works by examining the position of the stars.  And, how some archeologists and paleontologists willingly deal with some very old dung to learn secrets of the distant past.Guests:
      Samuel K. Wasser - Professor of conservation biology, University of Washington
      Jacob Berkowitz - Author of Jurassic Poop
      Russell L. Doescher - Physicist and astronomer, Texas State University
      James Oberg - Rocket scientist and media consultant

           It looked like no more than an oversized grapefruit with whiskers.  So you wonder what all the fuss was about.  But the small silver ball kicked into orbit by the Soviets in 1957 set off a decades-long space race between the U.S. and the U.S.S.R.  That race resulted in major accomplishments during the fifty years since Sputnik's spunky spin, including landing humans on the moon.Meet the new space race(s). Private companies are gearing up to go where only governments have gone before, and the launch of a Chinese lunar probe signals a new turf war over Earth's natural satellite.  We'll hear these stories, plus meet a "Sputnut" who owns two copies of the pioneering orb and is looking forward to a Sputnik-eye-view of Earth as a passenger on board the International Space Station next fall.Also, why the space elevator biz is looking up.Guests:
      Richard Garriott - Executive Producer at online game company NC Soft and a space enthusiast who is scheduled to fly to the International Space Station in October, 2008
      Peter Swan - Partner, Teaching Science and Technology, Inc. 
      Simon "Pete" Worden - Center Director, NASA Ames Research Center

           The north and south poles are hot news right now, but for disturbing reasons.  As the Earth's atmosphere warms, ice at high latitudes is melting at alarming rates.  You're undoubtedly aware of this massive melt and even feeling anxiety about it.  But, due to global-warming-news-fatigue, in which the relentless onslaught of climate statistics has frozen your brain like a Popsicle, you can't explain why it matters.We can help.  Tune in and find out why it's bad news if our frozen frontiers turn to mush and slush, as we talk with scientists who are breaking the ice as part of the International Polar Year, a collaboration to expand research and raise awareness of the Arctic and Antarctic, and the global climate system.Check out the Polar Palooza and International Polar Year websites.
