Lightning & Migraine
Migraine headaches are associated with lightning storms.
THE CHANGING ENVIRONMENT - What a scallop's cough can tell us about environmental health, how melting Arctic ice may have caused the earth's last big freeze, and why climate change may have undone the Maya empire. Also: using weather forecasting techniques to predict flu outbreaks, and revisiting the apocalypse myth surrounding the fictional planet Nibiru.
The new science of paleotempestology studies ocean sediment to uncover ancient hurricanes.
Cosmic rays called muons could help detect uranium in damaged Japanese nuclear reactors.
Airborne wind turbines have the potential to meet half of the world’s energy needs by 2030.
INVENTION - More lifelike robots. Headlights that can see past raindrops. And a pair of goggles that could improve your memory. Also, scientists have developed the world's lightest material.
“Smart” headlights improve visibility by illuminating the road ahead, but not raindrops or snowflakes.
BIRDS & DINOSAURS - Scientists discover T. Rex's feathered cousin, did dino gas warm the ancient earth? And giant fleas that may have pestered the prehistoric giants.

Researchers have estimated the total number of Emperor Penguins in Antarctica using satellite images.
Raindrop impressions, preserved for 2.7 billion years, reveal clues about the early Earth's climate.
CHEMISTRY & LIFE - What 2-billion-year-old raindrop fossils can tell us about conditions on the early earth. What science is revealing about the artwork of Leonardo da Vinci and Vincent Van Gogh. And a breakthrough in materials science technology yields plastic that can repair itself.
AAAS 2012 ANNUAL MEETING SPECIAL - This week, we're coming to you from Vancouver, British Columbia, where scientists are gathering to tackle issues or global importance, such as how to boost crop productivity to feed a growing population, and making cookstoves safer for the world's poor.

Are cyclones and earthquakes related? Why recent bad winters may be the result of global warming. And what life might be like on a planet with two stars. Also: we answer a listener's question about the temperature of the sun.
Arctic warming may actually be keeping winters cold for now, while raising temperatures in the other three seasons.
