Help Keep Crash Course Free Forever!



The 2024 Crash Course Coin is here! These limited-release coins are small tokens, but they represent something massive: your ability to help us reach 2,000, 10,000, or 20,000 learners. This year, the coin showcases figs, which, for us, represent growth and knowledge. Archaeological evidence suggests that figs are one of the earliest cultivated crops, dating back more than 11 thousand years and actually pushing back previous understandings of when human agriculture began. The design reminds us that when we get curious about the world around us, we discover and create new knowledge. And that project of meaning-making connects us to the earliest humans, and all the generations yet to come, all around the world. People like you make it possible for Crash Course to keep providing high-quality educational material that’s accessible and free. Thank you for purchasing coins, supporting us on Patreon, and sharing our videos. Learn more about the coin and how to get one at https://crashcoursecoin.com/?utm_source=CC&utm_medium=YTDescription&utm_campaign=CCC24 And if you're a Patron supporter passing your 3-year mark of support this year, we have a special coin available just for you.

The tech that seems to break the laws of physics - Anna Rothschild



Dig into the science of how heat pumps both heat and cool a home, and find out the benefits and drawbacks of this technology. -- Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for every bit of energy you put in, you get three to five times as much heat out. What wizardry is this? Anna Rothschild investigates the science of heat pumps. Lesson by Anna Rothschild, directed by Kevin Herrmann, AIM Creative Studios.

Stingless Bees Guard Tasty Honey With Barricades, Bouncers and Bites | Deep Look



The honeybee that sweetens your tea isn’t the only kind of bee that makes honey. More than 600 bee species across Mexico, Central and South America, and other tropical regions worldwide, also make the sweet stuff. But they don’t have stingers to defend their precious product. So, how do they keep thieves away? And what does their honey taste like?

See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small. --- Stingless bees build their nests mainly in the hollows of living trees, anywhere from rainforests to cities. Deep Look filmed four species kept by stingless beekeeper Emilio Pérez in the state of Oaxaca, in southwestern Mexico. He keeps Melipona beecheii, Scaptotrigona pectoralis, Scaptotrigona mexicana and Nannotrigona perilampoides to sell their honey. Stingless bees have evolved different ways to protect their honey and larvae from mammals and insects that want to eat them. Every night, tiny black bees with green eyes called Nannotrigona perilampoides cover the entrance to their nest with a barrier built out of cerumen, a material that stingless bees make by mixing wax with resins they collect from trees and other plants. The smell and stickiness of the resins keep ants away. Stingless bees also post guard bees at their nest entrance. And when defensive strategies don’t work, they tangle in their enemies’ hair, bite them with their mandibles and sometimes even coat them with resin. --- What is the difference between a honeybee and a stingless bee? Honeybee is the common name for a dozen or so species in the genus Apis. Apis mellifera, the Western or European honeybee, and Apis cerana, the Eastern or Asian honeybee, are kept worldwide because they’re very productive. Their workers, all female, use stingers to protect their hives. Stingless bees, also known as meliponines, produce smaller amounts of honey than honeybees, though some species are very productive. Both honeybees and stingless bees live in colonies with worker bees and queens. --- Does the honey of stingless bees have beneficial health properties? In Latin America and Asia, stingless bee honey is sold as a health product to treat ailments like sore throats. Honeys from both stingless bees and honeybees have hydrogen peroxide, which is antimicrobial. Since stingless bees collect resins, pollen and nectar from a host of plants – many in the rainforest – scientists are studying their honey for chemicals that might have medicinal properties. “There are really interesting chemicals in there. Some of them have known properties and it’s usually antifungal, antibacterial, even antiviral and anti-inflammatory, said entomologist David Roubik, who studied these bees at the Smithsonian Tropical Research Institute in Panama. “If all those things apply to every kind of stingless bee, I seriously doubt it. It does depend on what kind of flowers they’ve been visiting and what kind of resin they collect.” ---+ More great Deep Look episodes: Varroa Mites Are a Honeybee’s 8-Legged Nightmare https://youtu.be/69Do8tw_xy0?si=c4D-kc55iGihV2Oe Honeybees Make Honey ... and Bread? https://youtu.be/sAKkjD3nEv0?si=kOml9j36VtmtXViJ ---+ Shoutout! 🏆Congratulations🏆 to these fans from our Deep Look Community Tab for correctly answering our GIF challenge!

Item 2: Although surprisingly maneuverable, at their peak a European full suit of armor weighed about 200 pounds, so that knights would require a hoist to assist them onto horseback. Item 3: Graphene-based body armor has been shown to have twice the stopping power as Kevlar, and 10 times that of steel. Segment #6.
