Big Picture Science

There’s no harm talking to your houseplant, but will your chatter really help it grow? We look at various biological claims, from whether plants feel pain to the ability of cats to predict earthquakes. Feline forecasters, anyone? Also, when does understanding biology have important implications for health and policy? The arguments for and against genetically modified foods, and the danger of “pox parties” as a replacement for childhood vaccination. Plus, the history and current state of scientific literacy in the United States. When did we stop trusting science? Guests: Andy Michael - Seismologist with the U.S. Geological Survey in Menlo Park, California Ron Lindsay - President of the Center for Inquiry, headquartered in Amherst, NY Steven Novella - Clinical neurologist and Director of General Neurology at Yale University School of Medicine; host of the Skeptics Guide to the Universe podcast Shawn Lawrence Otto - Author of Fool Me Twice: Fighting the Assault on Science in America Chelsea Specht -

Wish you could ditch computers? There’s no escape button for that. Computers are not only a part of your daily grind, they may soon be a part of you. We’ll hear from the world’s first cyborg about why we should make nice in our arms race with machines. Also, the secret behind the extraordinary breakthroughs that DARPA scientists are making – from building autonomous cars to wiring robotic surgeons. Plus, making space for humans… and their bodily functions: the engineering tricks of toiletry. And, a carbon-based astronaut on the view of Earth from orbit.

Think small! Microbes are tinier than the dot at the end of this sentence, yet they can make humans sicker than dogs, dogs sicker than humans, jump from animal to human and keep scientists guessing when and where the next disease will appear. Discover how doctors diagnosed one man’s mysterious infection, the role that animals play as hosts for disease, and why the rate of emerging diseases is increasing worldwide. Also, why your kitchen is a biosafety hazard, and how the Human Microbiome Project will tally all the microbes on – and in - you. Plus, the extreme places on Earth where microbes thrive and what it suggests for the existence of alien life. And, how one strain of bacteria helped a farmer grow a pumpkin the weight of a small car! Guests: Peter Hudson - Biologist, Director of Life Sciences at Penn State University Peter Krause - Senior research scientist at the Yale School of Public Health Durland Fish - Epidemiologist at the Yale School of Public Health.

“Making space for everyone” could be NASA’s motto. But as commercial spaceships get ready to blast off, that populist idea is being tested. Space cowboys in the private sector say they’re the ones who can provide unfettered access to space, for tourists and scientists alike. Meet a scientist who already has a ticket to ride on SpaceShip Two and discover what he hopes to learn about asteroids during his five minutes of weightlessness. Plus, NASA in motion: it’s back to the moon as the GRAIL mission probes the interior of our lovely lunar satellite. Also, can you dig it? The rover Curiosity can. It’s headed to Mars to hunt for clues to alien life … with a jackhammer. Also, as the Hubble Space Telescope shuts down, the James Webb Space Telescope revs up. Or does it? The telescope is designed to study the birth of galaxies and hunt for evidence of water on far away worlds. But will Congress pull the plug? Guests: James Oberg - former Space Shuttle Mission Control engineer, and space expert Maria Zuber - Plane

What you can’t see … can make you sick. Humans have been battling viruses and bacteria since the beginning of time. The malaria parasite has been keeping deadly company with us for 500,000 years. King Tut had it and so did Julius Caesar. What’s keeping this bug going today? Also, how disease almost halted the most ambitious engineering project in the world … how elite disease detectives puzzle out perplexing epidemics … And – could tiny bugs from spaaace, ace, ace be our ancestors? Guests: Sonia Shah - Author of The Fever: How Malaria Has Ruled Humankind for 500,000 Years Michael Conniff - Historian, director of Global Studies at San Jose State University, and author of Black Labor on a White Canal: Panama, 1904-1981 (Pitt Latin American Series) Mark Pendergrast - Author of Inside the Outbreaks: The Elite Medical Detectives of the Epidemic Intelligence Service Robert Zubrin - President of the Mars Society Descripción en español First aired August 2, 2010 Learn more about your ad choices.

Shh - can you keep it down? Nope. Not unless you want to do away with civilization. Our buzzing, humming, whirling, machine-driven world is a poster child for technological progress, right? As is hearing loss. It’s driven one man to search the world for silence. We’ll hear what he didn’t hear, and what Einstein predicted we should hear in deep space, where gravitational waves may reveal the hidden sounds of the universe, including the birth of black holes.

Anyone who does gardening knows that life is tough. It’s also ancient – the first living things appeared on this planet nearly as soon as our world was habitable. We consider life on real worlds – like Earth and Mars – as well as fictional ones, such as the desert planet from the movie “Dune”. We’ll hear about a new scheme to find Martians, and practical approaches to coping with climate change. And is Pluto seeking revenge? The unmasking of a fourth moon around this former planet!

It’s been ten years since the fall of the Twin Towers, but some still believe that the attack was an inside job. They’re not the only ones to buy into a conspiratorial view of world events. Others deny President Obama’s American birth… link autism with vaccines… and even claim that the fluo ride in our drinking water is there to control our minds. Is it the truth - or the fringe groups - that are “out there?” Find out why some tinfoil hat ideas never go away. Also, the roots of rational argument: did our brains evolve to seek the truth… or just win arguments? It’s Skeptic Check… but don’t take our word for it!
