|     2:43    |     NEWS    | Desperate for Food, Mother Polar Bear Tests Walrus When we first found this video, we didn’t know the story behind it. But we quickly learned that this starving mother polar bear is making a last-ditch effort to find food for her malnourished cub. A walrus would make a sufficient meal for the ursine pair, if only the mother could kill it. We have scientific evidence that polar bears are starving because the sea ice they hunt on is melting. This video is just another example of how climate change is taking a toll on some of our most iconic wildlife. —Elaina Zachos, online writer WATCH NOW SHARE

|     0:58    |     NEWS    | Bombardier Beetles Squirt Boiling Anal Chemicals to Make Frogs Vomit This might be the best headline I’ve had the honor of writing in my National Geographic career. Frogs like to eat bombardier beetles. Bombardier beetles don’t like being eaten by frogs. So the beetles eject a caustic, boiling mixture of chemicals at great force to aggressively persuade the frogs to vomit them back up. The result? A slimy—but living—beetle. And one great video title. Read more about this slimy science. —Nick Lunn, producer/editor WATCH NOW SHARE

|     5:31    |      101 VIDEOS    | How Are Selfies Harming Tigers? “Tiger cub selfies” may look innocent and adorable, but behind those social media posts lies a multi-billion-dollar industry that’s driving tigers toward extinction. Tiger farms in Asia “speed breed” cubs to meet tourist demand. When they grow up, the tigers’ parts are sold to feed a demand for traditional medicine and luxury goods in China. With twice as many tigers in captivity in Asia as in the wild, you’d think wild tigers wouldn’t be in the crosshairs. But poachers continue to target tigers.

|     11:03    |     SHORT FILM SHOWCASE    | How $10 Million of Old Movie Memorabilia Was Found by Accident I love movies and antique store finds—two things this video combines in an intriguing way. In 1999, Marilyn Wagner and DJ Ginsberg paid $2,000 for hundreds of boxes at an antique store in Omaha, Nebraska. They contained letterpress blocks used to print newspaper ads for movies released during the silent era through 1984. The collection is currently valued at over $10 million, and Ginsberg hopes it will go to a museum so the public can enjoy it. —Rachel Link, producer WATCH NOW SHARE

|     5:52    |     SHORT FILM SHOWCASE    | See the Quiet Beauty of Farm Life on the Scottish Isles In the bare, beautiful islands of Scotland’s Outer Hebrides, farmers like Donald John Macinnes still practice crofting, the traditional Gaelic small-scale system of agriculture. This meditative short film, lit by soft dawn light over expansive landscapes, gives us a glimpse at a very different way of being alive than what many of us experience in urban areas. — Rachel Brown, associate producer WATCH NOW SHARE
