    The coldest materials in the world aren’t in Antarctica or at the top of Mount Everest. They’re in physics labs: clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low give scientists a window into the inner workings of matter, and allow engineers to build incredibly sensitive instruments that tell us more about the universe.

    Lesson by Lina Marieth Hoyos, animation by Adriatic Animation.

  • 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.

    Uploaded 28-09-20

    --

    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? Hyunsoo No explains radiosurgery.

    Lesson by Hyunsoo Joshua No, directed by Hype CG.

    Uploaded 03-02-15

    Today, about one-tenth of the world’s population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? Daniel M. Abrams investigates how the uneven ratio of lefties and righties gives insight into a balance between competitive and cooperative pressures on human evolution.

  • Can you be awake and asleep at the same time? - Masako Tamaki

    Discover the phenomenon known as asymmetrical sleep, where parts of an animal's brain are asleep while other areas remain active.

    Uploaded 18-05-21

    --

    Many animals need sleep. But all of the threats and demands animals face don’t just go away when it’s time to doze. That’s why a range of birds, mammals, and even humans experience some degree of asymmetrical sleep, where parts of the brain are asleep and other areas are more active. So, how does it work? Masako Tamaki explores how animals' brains remain vigilant even at their most vulnerable.

    Lesson by Masako Tamaki, directed by Biljana Labović.
    Animated by Iva Ćirić, designed by Manja Ćirić.

Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.
