EXCLUSIVE: How “Glowing” Sharks See Each Other | National Geographic

Posted by

How do biofluorescent sharks see the world? The recent discovery of more than 200 biofluorescent marine creatures has sparked interest in the biological and ecological roles of this phenomenon. Marine biologist and National Geographic Emerging Explorer David Gruber delves into the study of how these creatures see by designing a “shark-eye camera” that replicates the vision of biofluorescent sharks. Gruber enters the deep waters of Scripps Canyon, off the coast of Southern California, to image glowing swell sharks without the aid of artificial light. The resulting footage shows that swell sharks see each other’s biofluorescent markings much better than other objects in the dark, blue sea.

Imagine Making One Dress You’ll Wear Every Day for Life | Short Film Showcase

Posted by

Roughly 10 women in a town in Sardinia still wear the traditional dresses they made as adolescents. These hand-embroidered garments are reversible, with the elaborately decorated side worn during major life events and a plain side worn on a daily basis. Filmmaker Andrea Pecora’s Desula captures the detailed creation of these dresses and the stories of some of the women who wear them.
