DAVID GREENE, HOST:

Scientists may have filled in a gap in one the fundamental theories of physics. We've always been told that magnets have two poles, north and south. But theory suggests there should be something called a magnetic monopole, a magnet that has either a north pole or a south pole but not both of them. So far no one has found this elusive magnetic monopole.

STEVE INSKEEP, HOST:

Now let's turn to a thought experiment. Imagine you're riding one of those glass elevators that takes you to the top of a skyscraper. You go higher and higher. The view gets better. The cars on the ground, the people down there look puny like ants. Researchers say if you imagine this, it can make you feel unaccountably better about yourself. It briefly raises your self esteem. But researchers also say this feeling can be bad for you.

NPR's social science correspondent Shankar Vedantam is here to explain why. Hi, Shankar.

Changing Climate In Argentina Is Killing Penguin Chicks

There's a patch of seashore along the coast of Argentina where hundreds of thousands of penguins make their home. It's called Punta Tombo. Dee Boersma, a conservation biologist at the University of Washington, has been going there for 30 years, and she's discovered that a changing climate is killing those penguins.

Researchers Watch As Our Brains Turn Sounds Into Words

Researchers are a bit closer to understanding one of the brain's greatest accomplishments: making sense out of spoken language.

An area of the brain that interprets speech contains cells that respond to the dozen or so basic units of sound we use to form words, according to a team from the University of California, San Francisco.

Some of these cells respond specifically to plosives, like the initial "puh" sounds in "Peter Piper picked a peck of pickled peppers," the team found. Other neurons respond to fricative consonants, like the "f" sound in the word "fish."
