How To Make Antivenom - Bitten by a venomous snake? There's hope! French scientist Albert Calmette developed the first snake antivenom in the late 1890s, and did such a good job that we use his technique to this day. Antivenom works by stimulating the production of antibodies which can smother venom's toxic effects, preventing spread and rendering them harmless. But how do you make it? Well, stay tuned to this episode of SciShow to find out.

Powers of Ten™ (1977)

Powers of Ten takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only a s a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker- with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell. POWERS OF TEN © 1977 EAMES OFFICE LLC (Available at www.eamesoffice.com)

THE CICADAS ARE COMING! - Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by...doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge, simultaneous swarms. 

The swarm is so huge that predators can't consume even a fraction of it, but so rare that predator populations can't sustain themselves between emergence events. Clever little things!

Marvelous Medicinal Maggots - Although it may sound crazy, many doctors use maggots today to clean wounds of dead and infected tissue. This process, called debridement, is important for preventing the spread of infection in a world of increasing antibiotic resistance. Hank has more details on the marvelous maggot in today's episode of SciShow.
