Some 66 million years ago, about 75 percent of species on Earth disappeared. It wasn't just dinosaurs but most large mammals, fish, birds and plankton. Scientists have known this for a long time just from looking at the fossil record. If you dig deep enough, you find lots of dinosaur bones. And then a few layers up, they're gone.

But scientists couldn't figure out exactly what had caused this phenomenon. Of course, there were lots of theories.

  What can physics teach us about finance? A great deal according to physicist and mathematician James Owen Weatherall. He says markets can be understood, and to a degree even predicted, by using principles of physics. Ross Reynolds talks to professor Weatherall about what physics can teach us about Wall Street.

Not Easy To Find Room For Ocean Energy

GLENEDEN BEACH, Ore. - It goes without saying that the Pacific Ocean is vast. So it may come as a surprise to hear the sea described as "crowded." Perhaps even too crowded to make room for the nascent industry of wave and tidal energy.  Taxpayers and investors have pumped tens of millions of dollars into finding ways to turn the ocean's power into electricity.  In recent weeks, high stakes negotiations to identify wave energy sites on the Oregon Coast are finally getting somewhere.

Science Finds Evidence Of "Zombifying" Parasites

A parasite worms its way into a host, hijacks its nervous system and begins to control their behavior. Sounds like T.V. or the movies, but scientists have long known that parasites can take over and manipulate invertebrate and some vertebrate hosts. We talk with Dr. Shelley Adamo of Dalhousie University about how parasites may be turning hosts into zombies.

LONG BEACH, Wash. – It’s been more than four months since the last confirmed piece of Japanese tsunami debris washed ashore on the Pacific Northwest coast. Even sightings of suspected disaster debris have tapered way off in recent months. Does that mean we’re just in a lull or past the worst of it?

Every (Other) Breath You Take

Marine microbes are not as cute as sea otters, but they do produce about half the oxygen on the planet.  Meaning you have microscopic marine microbes to thank for every other breath you take.  And University of Washington oceanographer Ginger Armbrust just received a multi-million dollar grant to study marine microbial ecology from the Gordon and Betty Moore Foundation.  

Ross Reynolds talks with Professor Armbrust about the latest science on the microbes that we can thank for every other breath.
