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.

What gives opals their signature shimmering colors? Dig into the science of the gemstone’s formation, millions of years in the making. -- In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey’s Comet opal. Thanks to a characteristic called “play of color,” no two opals look the same. So what causes these vibrant displays? Jeff Dekofsky digs into the rock’s shimmering, dancing displays of light. Lesson by Jeff Dekofsky, directed by Ivana Bošnjak and Thomas Johnson.

Discover the ocean’s hidden kelp forests, and explore how these light-dependent organisms evolved to survive at dark depths. -- Like any other plant, kelps require light to grow. Yet kelps found nearly 90 meters below the ocean's surface, where sometimes only 0.1% of sunlight can reach, grow as large as, and often even larger than, their shallow counterparts. So how have these large, light-dependent organisms adapted to thrive at such depths? Luka Seamus Wright and Salomé Buglass explore the ocean's hidden forests. Lesson by Luka Seamus Wright and Salomé Buglass, directed by Upamanyu Bhattacharyya, Otter Studios.
