Jacob Margolis

KPCC's Science Reporter

Jacob's time in journalism began when he was 16, when he'd skip high school to spend his days working on the mid-day newscast at KPFK in Los Angeles.

Since then he's worked at NPR in Washington, D.C., as a producer on "The Madeleine Brand Show" and "Take Two" at KPCC and as a reporter, covering the political and social impact of California's new marijuana industry.

Now, he's the science reporter for the station.

What Cassini saw on Titan: 'Dunes of the Arabian desert' but made of water chips, not sand

It's so cold on Titan that its equator is nothing but dunes as far as the eye can see. But, they're not made of sand. They're made of little chips of water.

The little enzyme that could help fight global warming

Scientists from USC and Cal Tech have found that a certain enzyme can greatly speed up the process of transforming carbon dioxide into alkaline water.
