The brutal medieval king who inspired "Macbeth" - Benjamin Hudson
Dig into the history that inspired Shakespeare’s tragedy, “Macbeth,” and find out just how much of the play is based on real events. -- Of all Shakespeare’s plays, perhaps none is stranger than “Macbeth”— a parable on power rife with supernatural elements. But according to texts from the 11th century, this tragedy has its roots in reality. What’s more, other accounts mention witches, prophecies, and arboreal armies. Which raises the question: just how much of Shakespeare’s strange story is true? Benjamin Hudson investigates. Lesson by Benjamin Hudson, directed by Sarah Saidan.

Why do we get two tides each day? - Elise Cutts
Dig into how the Sun and Moon are responsible for the tides on Earth, and what this force looks like on other celestial bodies. -- In the 17th century, Isaac Newton offered the first gravitational explanation of tides. As he correctly identified, tides are choreographed by the motions of celestial objects, and Earth’s tides in particular are mostly driven by the Moon. But the precise nature of this relationship is actually quite nuanced. Elise Cutts explains how the Sun and Moon are responsible for the tides.

What causes opioid addiction, and why is it so tough to combat? - Mike Davis
Explore the science of why opioids are addictive and what can be done to reverse the growing rates of addiction and overdose. If you or someone you know is struggling with opioid use in the United States, the Department of Health and Human Services operates a helpline (800-662-4357) and has a database of treatment facilities: https://www.hhs.gov/opioids/ -- In the 1980s and 90s, pharmaceutical companies began to market opioid painkillers aggressively, while actively downplaying their addictive potential. The number of prescriptions skyrocketed, and so did cases of addiction, beginning a crisis that continues today. What makes opioids so addictive? Mike Davis explains what we can do to reverse the skyrocketing rates of addiction and overdose. Lesson by Mike Davis, directed by Good Bad Habits.

The fix for our energy challenges is … a toaster - Rachel Yang
Dig into the science of thermal batteries, and how this technology can generate heat more efficiently than fossil fuels. -- Industrial manufacturers spend a huge amount of energy generating heat to make everyday materials and objects, like cement, steel, and paper.

As a young surgeon, Peter Attia felt contempt for a patient with diabetes. She was overweight, he thought, and thus responsible for the fact that she needed a foot amputation.

Could the precursors to diabetes cause obesity, and not the other way around? A look at how assumptions may be leading us to wage the wrong medical war. Talk by Peter Attia.
