Plants may not seem like they live the most exciting lives, but two new papers published this week point to different types of plants that are actually very cunning and manipulative. One, the parasitic dodder, steals both nutrients and DNA from its host, and the other gives leaky gut syndrome to pests that try to eat it. Hosted by: Hank Green SciShow has a spinoff podcast!

Thank you to our Patreon patrons and Draper's "We Hack the Moon" initiative for supporting this very special episode of SciShow. Go to https://wehackthemoon.com to learn more about how engineers guided us to the moon and back with a fraction of today's technology. The Apollo program was famous for being risky and expensive. It had a crunched timeline, daring astronauts, and lacked modern tech, and that all kind of makes you wonder… was the Apollo program a bad idea?
