|     1:31    |     NEWS    | Watch a Cougar Face Off With Hikers Cougars are ambush predators. No other video I've seen displays that better than this footage of two hikers encountering a mountain lion on the trail. After they follow the big cat around a corner, there's a brief moment of confusion as the cameraman tries to spot it. And then you see it. Blended perfectly into the background, the cougar stares silently down, no more than 15 feet away. It's a chilling moment, even watching from the safe confines of your screen. The hikers slowly backed away unharmed. —Nick Lunn, editor WATCH NOW SHARE

|     1:00    |     NEWS    | A Mysterious Amazon Animal Seen for the First Time in 80 Years I'll be honest—when I first pitched this article, I just wanted to write about a monkey with a Beatles haircut. But then I spoke to Laura Marsh, a scientist who has spent her life studying saki monkeys. She explained how the trip began as a search for the elusive creature, and evolved into something grander. —Sarah Gibbens, online writer WATCH NOW SHARE

|     2:38    |     101 VIDEOS    | Climate 101: Oceans The ocean isn't exempt from the effects of climate change. Before I started working on this video, I had never heard of one of those effects: ocean acidification. It sounds simple to understand—the ocean is getting more acidic, right? But the process is a little more complicated than that. To explain it, I visualized how greenhouse gases are changing the chemical composition of the ocean—and I hope the results will inspire people to dive deeper into all the ways we can protect our oceans. —Rebekah Barlas, producer WATCH NOW SHARE

|     9:35    |     SHORT FILM SHOWCASE    | Meet the Last Speaker of a Dying Language For indigenous communities around the world, preserving traditional languages means preserving an entire history and way of life—but language revitalization faces so many challenges. How do you keep alive a language with only a hundred speakers, or ten, or one? Marie Wilcox’s painstaking, years-long effort to make a Wukchumni dictionary—and teach the language to her daughter and grandson—is a quietly powerful story of how communities keep their culture alive. —Rachel Brown, associate producer WATCH NOW SHARE
