Could the future of farming rely on pooping fish? Considered to be a sustainable alternative to traditional farming, aquaponics is changing the way we grow food. ➡ Subscribe: http://bit.ly/NatGeoSubscribe About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

It works by raising fish and plants together in a contained water system. The fish produce waste, which is filtered to remove solids and transformed into nutrient-rich water through a two-step bacterial process. The enriched water is then pumped into a separate tank where seedlings float on soil-free growing beds, illuminated by special LED lamps that provide optimal light for growth. Through this method, crops grow 20 percent faster than plants grown using traditional farming techniques. For that reason, aquaponics is emerging as a sustainable option for cities, islands, and developing regions where land and water resources may be limited. Learn how this ever evolving technique is growing food for the future in this latest video from Decoder: https://www.youtube.com/playlist?list=PLivjPDlt6ApQYPw1BUw0ziY-ztWAKOdSG For more, read "From Tank to Table" in the August 2019 issue of National Geographic magazine.

For the past 23 years Andrea Ghez, professor of physics and astronomy at UCLA, has been collecting data on stars that orbit black holes. She found that their motion provided an opportunity to test the fundamental laws of physics. “We asked how gravity behaves near a supermassive black hole and whether Einstein’s theory is telling us the full story. ”Einstein’s 1915 theory of general relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. “In Newton’s version of gravity, space and time are separate, and do not co-mingle; under Einstein, they get completely co-mingled near a black hole,” she said. Ghez's research is the most detailed study ever conducted into the supermassive black hole and Einstein’s theory of general relativity. ➡ Subscribe: http://bit.ly/NatGeoSubscribe ➡ Get More Short Film Showcase: http://bit.ly/ShortFilmShowcase About Short Film Showcase: The Short Film Showcase spotlights exceptional short videos created by filmmakers from around the web and selected by National Geographic editors.

In this episode we witness one of the Arctic’s most magical moments. With the help of a one-of-a-kind local tracker, we find a female polar bear fresh out of her winter den with her tiny new cub. We see ultimate cuteness as the cub explores the world outside for the first time. Their irresistible interactions distract from the fact that the mother bear is actually making an impossible decision. The mother has spent the last eight months starving, so she is eager to rush to the ocean where she can hunt. But to reach the seal feast means a 40-mile trek. Does she wait to allow the cub to gain strength for the long trek, or does she head out to sea to make sure her milk doesn’t dry up? We also follow a young female bear in her first moments of independence, having been kicked out by her mother. She has spent the last two and a half years with her mother preparing for this moment, but she quickly manages to get herself into trouble. Will she be able to survive a wolf on the hunt? ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #BertieGregory #WildlifeTheBigFreeze About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

Polar bears dominate the Arctic animal headlines; it’s hard for anything to escape their shadow. In this episode we meet an unexpected array of smaller species that each have their own peculiar but no less entertaining strategies for surviving in this brutal environment. The tiny arctic fox might look cute, but it’s actually a killing machine. The arctic hare may be fluffy and have comical ears, but it’s both a master of camouflage and one of the fastest animals here. The snowy owl has sacrificed speed for a mightier secret weapon: silence. We find a lemming (a tiny brown rodent) running around in a blizzard, a big mistake when silent assassins are flying overhead. Although these unsung heroes are some of the few who’ve perfectly adapted to this place, the environment is changing fast. Warming temperatures are allowing enemies to move north, encroaching on these Arctic specialists. ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #BertieGregory #WildlifeTheBigFreeze About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

Can spiders fly? When you think of the greatest aviators in the natural world, you probably think of the usual winged suspects like birds, bees, and butterflies.

In fact, some of the longest arachnid flights lasted for thousands of miles. Today, scientists widely debate the exact science behind spiders' ballooning, but one prominent theory suggests that spiders could be using the electric field in earth's atmosphere, in addition to the wind, to provide lift to their silk strands and send them sailing away. Discover the amazing aerodynamics of spiders' wingless flight in this latest video from Decoder. For more, read "Soaring Spiders" from the May 2019 issue of National Geographic magazine.
