Water, water everywhere. But most of it is sea water - you can’t drink it. Discover the most promising technologies for desalination and why solar cells are key. Also, how astronauts filter “water-closet water” to drink it, and how to turn a salt pond back to a wetland. Plus, from Roman aqueducts to modern-day pumps: a history of quenching human thirst.

How did life begin? What’s the universe made of, and what’s the nature of consciousness? These are truly some of the biggest puzzlers in science, but answers are in the offing. We consider the modern-day hunt for life beyond Earth, as well as a new theory of consciousness: could it be merely an illusion to entertain us and make our lives more worthwhile? Also, after thousands of years of examining the heavens, are we finally learning the true nature of the cosmos?

They’re heeeere! Yes, aliens are wreaking havoc and destruction throughout the land. But these aliens are Arizona beetles, and the land is in California, where the invasive insects are a serious problem. And what of space-faring aliens? We have those too: how to find them, and how to protect our planet – and theirs. From Hollywood to SETI’s hi-tech search for extraterrestrials, aliens are invading Are We Alone?

Physics means getting physical if you’re tackling the biggest, most mysterious questions in the universe. Stoic scientists endure the driest, darkest, coldest spots on the planet to find out how it all began and why there’s something rather than nothing. From the bottom of an old iron mine to the top of the Andes, we’ll hear their stories. Plus, Steven Weinberg on this weird stuff called dark energy, and Leonard Susskind sees double, no, triple, no, …infinite universes.

Memories are slippery things – some are crystal clear, others more like a muddy pool, and some… well, they seem to vanish completely. Scientists admit that memory is all very complicated, but one piece of the puzzle lies in how we age – we’ll hear the latest research. Meanwhile, meet the man who digitally logged his every waking moment - and why maybe the secret to happiness isn’t in remembering but in forgetting. Plus, the case for deleting data from your hard-drive… and from your brain itself.

The end is nigh. Only, on which nigh should we rely? According to billboards, Judgment Day is in May and the end of the world follows months later. But other authorities claim 2012 as the apocalyptic year, as predicted by the ancient Mayans. It’s a busy time for doomsday prophecy. Find out what’s driving these pessimistic predictions and whether it’s time to cash in your stock portfolio. Meanwhile, a survey of the real threats to Earth, and indeed to the universe, from asteroids, exploding stars, or a big cosmic rip. And the lingering menace of atomic weapons... Is nuclear war inevitable or can intelligence and political will forestall atomic Armageddon? Finally, why everything’s going to be alright! An optimist’s tour of the future. It’s Skeptic Check, our monthly look at critical thinking on Are We Alone. Guests: Phil Plait - Astronomer, and author of the Bad Astronomy blog at Discover Magazine Ron Rosenbaum - Author of How the End Begins: The Road to a Nuclear World War III Catherine Wessinger - Pro

The universe is big – really big.* Galaxies, for instance, are often large enough to hold a trillion stars. But how did these heavenly heavyweights come to be? Hear how still-mysterious dark matter is implicated in the birth of galaxies. Also, gamma ray bursts - explosions more energetic than anything since the Big Bang - take place somewhere in the visible universe every day. What are they, and could they obliterate life on Earth? And, the biggest cosmic mystery de jour: dark energy. Why new, super-size telescopes may finally reveal just what it is. We’re living large on “Big, Really Big.” *appreciative nod to Douglas Adams Guests: George Djorgovski - Astronomer, California Institute of Technology Sandra Faber - Astronomer and Chair of Astronomy and Astrophysics, University of California at Santa Cruz; leads the CANDELS survey that uses the Hubble Space Telescope to image more than 250,000 distant galaxies Daniel Perley - Astronomer, University of California at Berkeley Ed Stone - Former director of

Public distrust of science is higher than at any time since the Enlightenment. New Yorker writer Michael Specter argues how our anti-science bias and our irrationalism about everything from genetically modified foods to climate change to childhood vaccines endangers our future. And remember when… a look back at scientists who at first pooh-poohed plate tectonics... meteorites, and quantum physics. How the evidence turned them around. It’s Skeptic Check… but don’t take our word for it.

Birds do it. Bees do it. But no one sings about how they do it. And frankly, not even Cole Porter can make bedroom behavior that involves decapitating your mate sound romantic. And what rhymes with “cannibalism?” But the animal world abounds with bizarre sexual behavior… and it’s all perfectly normal. Find out how female spiders lure males to their doom… why dolphins are the friskiest of mammals… whether E.T. would have sex… and why sexual reproduction evolved in the first place. Also, why the marketing gurus have it all wrong: driving a Hummer or wearing Gucci won’t help you land a mate. Find out what will.

Being first counts in science. Land that coveted spot and you’ll make history, whether it’s with the first steam engine or the discovery of our earliest human ancestor. But what does “first” mean when technological invention so heavily builds on what’s come before... and evolution represents continuous change? Find out how “publish or perish” made Darwin famous… why we’ll never find the first human fossil… and how powerful new telescopes are allowing us to see the earliest galaxies.

From the double-helix to the expansion of the universe, great scientific discoveries reshape our understanding of who we are and how things work. But great discoveries require more than just a great mind. We tour brainy breakthroughs from Archimedes to Darwin, and find out what made their revolutionary insights possible. Also, why you need more than a stratospheric I.Q. to be a super-achiever. And how the invention of reading re-directed the course of civilization and re-wired our brains in the process.

The weaker the mixture, the stronger the potency. That paradox is a central tenet of homeopathy. More than 200 years old and developed long before germ theory, the practice is the fastest growing form of alternative medicine worldwide. Proponents say its diluted remedies cure disease. Most scientists maintain there’s nothing in homeopathic solution but water. We’ll hear the arguments, and also the role placebos might be playing in the cure. Plus, skeptic Phil Plait voyages to the edge of the solar system where a new planet has been discovered … maybe! And, consider our brains: the product of millions of years of evolution. So why aren’t we more consistent in our reasoning? It’s Skeptic Check…. but don’t take our word for it. Guests: • Iris Bell – Psychiatrist and researcher in alternative medicine at the Arizona Center for Integrative Medicine •  Simon Singh – Science writer based in the U.K., author of Trick or Treatment: The Undeniable Facts about Alternative Medicine •  Phil Plait – Astronomer, skeptic, an

Earth may not be rare after all. New data from NASA’s Kepler mission suggests that the universe is chock-a-block with planets. More than a thousand new possible planets have just been found, and more than fifty of these might be suitable for life. Ready for cosmic company? We discuss the results of the Kepler mission in a roundtable with some of its top scientists. Meanwhile, the Voyager spacecraft continues to be humanity’s point man in the race to interstellar space. Poised to leave our solar system, we reflect on the mission – including its on-board messages for aliens. Plus, out-of-this world science. From lab coats to warp speed: does Hollywood get it right?

You’re right: it’s a show about ESP. And, correct again: we’re excited about the publication of a paper that claims precognition exists. You’ve already divined what our paranormal investigator says about the paper, whether the statistics that it cites are significant, and what the editor-in-chief of a major scientific journal has to say on the tricky matter of publishing such a result at all. You’re not surprised that Brains on Vacation takes on the matter of Armageddon-by-exploding-star, because, you knew that. You also knew that it will be an excellent show.
