Dozens of scientists recently glued fake green caterpillars onto plants around the world in an unusual study to see how the caterpillars' risk of getting eaten varied from pole to pole.

Any ant, slug, lizard, bird or beetle that attacked the soft clay caterpillars left telltale bite marks that were later analyzed by a lab in Finland.

Ten years ago, University of Washington professor David Montgomery published his influential book “Dirt: The Erosion of Civilizations.” One year later, he received a MacArthur Genius fellowship, and continued his research in geomorphology: “the branch of geology that is concerned with the structure, origin, and development of the topographical features of the earth's surface.”

It had been a timeless love story. A garden snail with a rare genetic condition can't mate with normal snails; scientists launch an international search for a mate; the snail becomes a media sensation; and miraculously not one but two possible mates are found.

That's where we left the tale of Jeremy, the rare left-coiling snail, last November.

The dark side of moderating Facebook

May 15, 2017

Bill Radke spoke with UCLA assistant professor Sarah Roberts about the psychological risks of moderating social media platforms like Facebook, Twitter and Instagram. Roberts describes some of the personal issues moderators have faced by viewing objectionable material. She also describes ways in which such a difficult job could possibly be made better. 

Bears do it; bats do it. So do guinea pigs, dogs and humans. They all yawn. It's a common animal behavior, but one that is something of a mystery.

There's still no consensus on the purpose of a yawn, says Robert Provine, professor of psychology and neuroscience at the University of Maryland, Baltimore County. Provine has studied what he calls "yawn science" since the early 1980s, and he's published dozens of research articles on it. He says the simple yawn is not so simple.

To the list of global problems the world’s oceans are facing, you can add another: They’re losing oxygen.

The Pacific Ocean off the U.S. West Coast, from central California to Alaska, is one of the hardest-hit areas.

Bill Nye is back. Netflix is now streaming episodes of “Bill Nye Saves the World,” starring everyone’s favorite bowtie-clad scientist. (And of course, we’re still a bit nostalgic for those olden times when Nye traded in his signature tie for exercise shorts and a cape, all for Seattle’s amusement.)


NASA's Cassini spacecraft is giving earthlings their closest-ever views of Saturn's swirled atmosphere and its massive hurricane, beaming a trove of images and data back to Earth after the craft made its first dive between Saturn and its rings Wednesday.

Cassini is "showing us new wonders and demonstrating where our curiosity can take us if we dare," said Jim Green, director of NASA's Planetary Science Division.

If all goes to plan, NASA's Cassini spacecraft will beam new images of Saturn and its rings to Earth early Thursday, sharing data collected Wednesday from its first dive through the gap between the planet and its striped belt of ice and rock particles.

Today's dive also marks the start of the final phase in the craft's 13-year visit to Saturn. Days ago, it used the gravity of Saturn's moon Titan to bend its path toward its eventual destruction on the planet.

Baby humpback whales seem to whisper to their mothers, according to scientists who have captured the infant whales' quiet grunts and squeaks.

The recordings, described in the journal Functional Ecology, are the first ever made with devices attached directly to the calves.

People around the world use more than a trillion plastic bags every year. They're made of a notoriously resilient kind of plastic called polyethylene that can take decades to break down.

But the humble wax worm may hold the key to biodegrading them.

It was an accidental discovery. Scientist and beekeeper Federica Bertocchini was frustrated to find that her beehives were infested with the caterpillar larvae of Galleria mellonella, commonly known as a wax worm.

David Montgomery, a science professor and MacArthur Genius award winner at the University of Washington, told KUOW why he's marching for science on Saturday.

The March For Science in Washington, D.C., is happening this Saturday on Earth Day. Smaller science events are happening across the Northwest -- even in conservative southeast Washington.
