Why is saffron so expensive? - Carolyn Beans

Dig into the unique biology of saffron and trace humanity’s enduring obsession with the spice, dating back thousands of years. -- Spices are often far pricier proportionately than the foods they flavor. But one’s cost has long topped them all. Saffron’s red threads regularly run at rates of over 600 USD an ounce. So what is this so-called “red gold,” and what makes it so expensive? Carolyn Beans digs into the unique biology of saffron and humanity's enduring obsession with the spice. Lesson by Carolyn Beans, directed by Sarah Saidan.

Copycats! This Ant Is Surrounded By Imposters | Deep Look

Green tree ants are a dominant species in tropical forests stretching from India to northern Australia. Aggressive, industrious and highly territorial, most of their neighbors don’t want to mess with them. With a reputation like that, over millions of years multiple animals evolved to mimic them– some to stay safe, and others to kill. 👉 Donate to KQED, the public media station that makes Deep Look: https://donate.kqed.org/deeplook SIGN UP for Deep Look’s newsletter, Nature Unseen: https://bit.ly/NatureUnseenSignUp SUBSCRIBE: https://www.youtube.com/@KQEDDeepLook?sub_confirmation=1 ---+ Find a transcript on KQED Science: https://www.kqed.org/science/2001529/copycats-this-ant-is-surrounded-by-imposters ---+ More great Deep Look episodes: This Fish Can Jump Almost as High as You Can https://youtu.be/CJl_relCddQ The Slimy Details Behind Banana Slug Mating https://youtu.be/1VGBy04nIjA This Stick Insect Has a Peppermint-Scented Secret Weapon https://youtu.be/BmPCRIwi0mg ---+ Thank you to our top Patreon supporters ($10+ per month)!

Steven Strogatz, for the insightful conversations, on-camera contribution, and careful reviews that helped us keep the mathematics clear and the story scientifically honest. Peter Sheridan Dodds, for helping us understand the objections to WBE theory and the debate over three-quarter-power scaling.
