Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests, sunlight may confer another surprising benefit too. New research by his team shows that nitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system.

Dig into the history of poker, from the game’s invention in the American South to its explosion of popularity across the world.

--

From its earliest incarnations, poker has always been a contest of guile, guts, and gambling. The game first emerged around 1800 in the melting pot of New Orleans, and soon spread up the Mississippi, Ohio, and Missouri rivers. So, how did this simple game of the American South skyrocket in popularity? James McManus shares how the card game became an international affair.

Lesson by James McManus, directed by Chintis Lundgren.

He was a powerful king whose break with the church of Rome would forever change the course of English history. But was he a charismatic reformer who freed his subjects from a corrupt establishment or a bullying tyrant who used Parliament for his own personal gain? Mark Robinson and Alex Gendler put this controversial figure on trial in History vs. Henry VIII.

Uncover the most common misperceptions about pandas, and find out why it's so difficult for them to breed in captivity.

--

In the 1930’s, a grand panda drama unfolded at the Chicago Zoo. Zookeepers procured a female panda named Mei Mei, and they were determined to find her a mate. They found a prospective suitor named Mei Lan, and the public eagerly awaited the patter of tiny panda paws. But the wait dragged on... and on. Why weren’t the bears breeding? Lucy Cooke shares common misperceptions about pandas.

Lesson by Lucy Cooke, directed by Keegan Thornhill.

Explore the construction of the futurist city Chandigarh, a project of Prime Minister Jawaharlal Nehru and planned by Le Corbusier.

--

In 1947, India achieved independence from British rule — but this freedom came at a tremendous cost. Jawaharlal Nehru, India’s first Prime Minister, was eager to usher his country towards a brighter, united future. And one of the projects that would prove most essential to realizing this vision was the construction of Chandigarh. Vikramāditya Prakāsh details the creation of the futurist city.

Dig into what happened after the Chicxulub asteroid hit the Earth, and how it caused a mass extinction— including dinosaurs.

--

Sixty-six million years ago, near what’s now the Yucatán Peninsula, a juvenile sauropod feasted on horsetail plants on a riverbank. Earth was a tropical planet. Behemoth and tiny dinosaurs alike soared its skies and roamed its lands while reptiles and tentacled ammonites swept its seas. But, in an instant, everything would change. Sean P. S. Gulick details one of Earth's most devastating periods.
