    What's worse than a wasp's sting? Slaughter - Miles Zhang

    Explore the gruesome evolutionary strategy employed by parasitoid wasps where they feed off other animals to grow their offspring. -- A cockroach and jewel wasp are locked in battle. The wasp latches onto the cockroach and inserts her stinger into the cockroach's brain, where her venom blocks its fight-or-flight response. Now, the cockroach is essentially a zombie, and its carcass will be used to grow the wasp’s offspring. Miles Zhang explores the gruesome evolutionary strategy known as parasitoidism. Lesson by Miles Zhang, directed by Denys Spolitak.

    How to perform brain surgery without making a single cut - Hyunsoo Joshua No

    Dig into the science of radiosurgery: a procedure that uses light beams of radiation to target tumors, without making a single incision. -- Every year, tens of thousands of people have brain surgery without a single incision: there’s no scalpel, no operating table, and the patient loses no blood. Instead, this procedure uses a machine that emits invisible beams of light at a precise target inside the brain. So how exactly does this treatment work? And what does it do to the tumors it targets?

    The ballet that incited a riot - Iseult Gillespie

    Dive into the history and controversy of Igor Stravinsky’s ballet, “The Rite of Spring,” which shattered the conventions of classical ballet. -- Ballet is typically thought of as harmonious, graceful and polished— hardly something that would trigger a riot. But at the first performance of Igor Stravinsky's “The Rite of Spring,” audience members were so outraged that they drowned out the orchestra. People hurled objects at the stage, started fights and were arrested. What caused this shocking reaction? Iseult Gillespie explains the controversy.

    Can democracy persist without trust? - Ivan Krastev

    Five great revolutions have shaped political culture over the past 50 years, says theorist Ivan Krastev.
