Short Wave - TASTE BUDDIES: Pucker Up! It’s The Science Of Sour

This week Short Wave is celebrating our sense of taste with an entire week of themed episodes, covering everything from sugar and spice to what's beyond our classic ideas of taste. It's a series we're calling, "Taste Buddies."

In today's encore episode with Atlantic science writer Katherine Wu, we take a tour through the mysteries of sourness — complete with a fun taste test. Along the way, Katie serves up some hypotheses for the evolution of sour taste because, as Katie explains in her article, "The Paradox of Sour," researchers still have a lot to learn about this weird taste.

This Machine Kills - Patreon Preview – 178. Fleshing out Fintech as a Systemic Phenomenon

Now it’s time to get into the real analysis of fintech as laid out by Saule Omarova’s work. We walk through the dominant regulatory approach to financial markets that came from the New Deal; how the 1980s is the true origin of the fintech revolution; how the secondary financial markets have taken over the whole system; how new technologies focused on making micro-level transactions faster, easier, cheaper have led to making macro-level systems more unstable, unrestrained, and untethered from reality.

Everything Everywhere Daily - Great Zimbabwe (Encore)

Located near the city of Masvingo in Central Zimbabwe are the ruins of one of the greatest civilizations of the Middle Ages. 

When European explorers first discovered the ruins, they simply couldn’t believe that it was built by native Africans. 

Subsequent archeological investigations showed not just that they were wrong, but that the civilization which was there had contact with some of the furthest reaches of the known world. 

Learn more about Great Zimbabwe, one of Africa’s greatest empires, on this episode of Everything Everywhere Daily.
