Follow a neurosurgeon's attempts to perform a head transplant, and dig into the ethical and biological questions the procedure raises.

--

In 1970, neurosurgeon Robert White and his team carted two monkeys into an operating room to conduct an ambitious experiment. The objective was to connect the head of Monkey A to the body of Monkey B, in what he considered a whole-body transplant, with the ultimate goal of one day performing this surgery on humans. Is such a feat even medically possible? And is it ethical? Max G. Levy investigates.

Lesson by Max G. Levy, directed by Anton Bogaty.

Trace the life cycle of mayflies, and explore why these swarming insects are a sign of healthy aquatic ecosystems.

--

For most of the world’s 4,000 mayfly species, adulthood lasts roughly one day. And for some species, it’s only a matter of minutes. This isn’t because they’re all eaten up by predators. Rather, this abridged adulthood is a natural part of their life cycle. So, what role do these bugs play in their ecosystems? Luke M. Jacobus explores the stunningly short life span of the winged insects.

Lesson by Luke M. Jacobus, directed by Denys Spolitak.

Your professor has accidentally stepped through a time portal in his physics lab. You’ve got just a minute to jump through before it closes and leaves him stranded in history. Your only way back is to grab enough colored nodules to create a new portal to open a doorway through time. Can you take the right amount of nodules to get back to the present before the portal closes? Dan Finkel shows how.

Learn about the Greek physician and philosopher Galen of Pergamon, whose experiments and discoveries changed medicine.

Uploaded 18-07-19

--

In the 16th century, an anatomist named Andreas Vesalius made a shocking discovery: the most famous human anatomy texts in the world were wrong. While Vesalius knew he was right, announcing the errors would mean challenging Galen of Pergamon. Who was this towering figure? And why was he still revered and feared 1,300 years later? Ramon Glazov profiles the most renowned physician in medical history.

So begins Zora Neale Hurston’s acclaimed novel “Their Eyes Were Watching God,” about a Black woman’s quest for love and agency. Tanya Boucicaut dives into this classic of the Harlem Renaissance.
