Our ability to speak doesn’t begin with our first words. It begins in the womb.

Whether you grew up speaking one or more languages, chances are you picked your first cues in utero. Scientists are learning much more about those early moments of language acquisition.

A hundred years ago, Einstein predicted the existence of gravity waves. Today, for the first time, scientists announced that they’ve actually been detected. Here’s what the discovery might mean for our understanding of the universe.

•January 20, 2016 • 1 Comment

About a decade ago, several of Greenland’s biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island’s rapidly-melting ice sheet.

Turning ice into fire. Iceland goes for drama.

A New Way to See the Brain

•October 2, 2015 • Leave a Comment

Scientists at MIT have embedded slices of brain in the absorbent material found in diapers, which swells 4-5 times its normal size. And when they look at the expanded result using an ordinary light microscope, they see an unprecedented view of nerve fibers, cells, and proteins. It’s the deepest look into the brain we’ve ever had.

Is an artificial tree part of the solution to climate change? These guys think so.

•September 3, 2015 • Leave a Comment

Trees are nature’s tool for pulling carbon dioxide out of the air, but there aren’t enough trees in the world to suck up all the CO2 humans are putting there. That’s why researchers are pushing to create artificial leaves to help fight climate change. I visit with two teams of researchers pursuing different approaches to the formidable challenge.
