When Ozgun Gokce was a child, his family’s television broke. Losing that TV prompted him to figure out why it went kaput. That initial curiosity led Gokce into a career of understanding why things break—specifically with disease. He is now a research scientist at the University of Bonn, where he investigates age-related neurological disorders and builds technologies to identify why and how brains degenerate.

Are cats smarter? Or are dogs? When scientists counted the brain cells in these animals, there was a clear winner. But the latest research on animal intelligence challenges all of the old-school notions of what it means to be smart.

Cycads co-existed with the dinosaurs, making this group of palm-like plants extremely valuable to collectors and botanic gardens around the world. But today, cycads are in peril.

In honor of “WestWorld” coming back for a second season -- which we expect to be no less baffling than the first -- the NewsHour asked its staff for recommendations for movies and TV shows that left us with questions.

What weighs more than 87,000 tons and is twice the size of #Texas? The Great #Pacific Garbage Patch, according to a study published Thursday.

In the report, @TheOceanCleanup estimates this soup of trash in the northern Pacific contains 1.8 trillion pieces of plastic — enough to give every person in the world 250 scraps of this debris.

To put these numbers in perspective, the #garbage in the patch weighs about as much as 1.7 billion plastic bottles, 43,000 #cars or 600 blue #whales. #science #environment #pollution
