“Sorry, closed for business.” That sign hung on doors of national laboratories when the US government shut down. What that meant for one Antarctic researcher: her critically important work was left out in the cold. So just what do we lose when public funds for science fade? The tools for answering big questions about our universe for one, says a NASA scientist … while one of this year’s Nobel Prize winners fears that it is driving our young researchers to pursue their work overseas. Yet one scie...
Oct 28, 2013•54 min•Transcript available on Metacast It was the most famous invasion that never happened. But Orson Welles’ 1938 “War of the Worlds” broadcast sure sounded convincing as it used news bulletins and eyewitness accounts to describe an existential Martian attack. The public panicked. Or did it? New research says that claims of mass hysteria were overblown. On the 75th anniversary of the broadcast: How the media manufactured descriptions of a fearful public and why – with our continued fondness for conspiracies – we could be hoodwinked ...
Oct 21, 2013•54 min•Transcript available on Metacast Your brain is made up of cells. Each one does its own, cell thing. But remarkable behavior emerges when lots of them join up in the grey matter club. You are a conscious being – a single neuron isn’t. Find out about the counter-intuitive process known as emergence – when simple stuff develops complex forms and complex behavior – and all without a blueprint.

Oct 14, 2013•54 min•Transcript available on Metacast Imagine: Your pint-sized pup is descended from a line of predatory wolves. We have purposefully bred a new species – dogs – to live in harmony with us. But interactions between species, known as co-evolution, happen all the time, even without deliberate intervention. And it’s frequently a boon to survival: Without the symbiotic relationship we have with bugs in our gut, one that’s evolved with time, we wouldn’t exist. Discover the Bogart-and-Bacall-like relationships between bacteria and humans,...
Sep 16, 2013•54 min•Transcript available on Metacast The Day After. 2001. Prometheus. There are sci-fi films a’plenty … but how much science is in the fiction?

Jul 15, 2013•54 min•Transcript available on Metacast What’s the world made of? Here’s a concrete answer: a lot of it is built from a dense, knee-scraping substance that is the most common man-made material.

Jul 08, 2013•54 min•Transcript available on Metacast You may be unique, but is your home planet? NASA’s Kepler spacecraft has uncovered thousands of planetary candidates, far far beyond our solar system. Some may be habitable and possibly even Earth-like. But now a failure in its steering apparatus may bring an abrupt end to this pioneering telescope’s search for new worlds. But Kepler has a massive legacy of data still to be studied. Many new worlds will undoubtedly be found in these data. Hear why the astronomer who has discovered the greatest n...

Jun 03, 2013•54 min•Transcript available on Metacast It’s a record we didn’t want to break. The carbon dioxide concentration in the atmosphere hits the 400 parts-per-million mark, a level which some scientists say is a point of no return for stopping climate change. A few days later, a leading newspaper prints an op-ed essay that claims CO2 is getting a bad rap: it’s actually good for the planet. The more the better. Skeptic Phil Plait rebuts the CO2-is-awesome idea while a paleontologist paints a picture of what Earth was like when the notorious ...
