    Can you freeze your body and be revived? - Shannon N. Tessier

    Dig into the field of cryobiology and explore the possibility of humans being frozen and preserved for future resurrection. -- In 1967, James Bedford had a plan to cheat death. He was the first person to be cryogenically frozen. This process promised to preserve his body until a theoretical future when humanity could cure any illness, and essentially, reverse death. So is it possible to freeze a human, preserve them indefinitely, and then thaw them out? Shannon N. Tessier explores the challenges of human cryopreservation. Lesson by Shannon N. Tessier, directed by Gavin Edwards, Movult.

    What happens if a manufactured virus escapes the lab?

    How do we keep labs that handle dangerous pathogens safe and leak-free? Dig into the ongoing debate over virology research. -- Since the 1970s, researchers have engineered superbugs. While this research could help us prepare for future outbreaks, the stakes of this work are extremely high: if even one dangerous virus escaped a lab, it could cause a global pandemic. So, what can we do to minimize risk? And is the knowledge gained even worth the risk in the first place? Dig into the ongoing debate over virology research.

    Why do we have hair in such random places? - Nina G. Jablonski

    Discover how humans lost their fur as they evolved from primates, and why we still have hair on our bodies. -- We have lots in common with our closest primate relatives. But comparatively, humans seem a bit… underdressed. Instead of thick fur covering our bodies, many of us mainly have hair on top of our heads— and a few other places. So, how did we get so naked?

    How do airplanes actually remain in flight? - Raymond Adkins

    Explore the physics of flight, and discover how aerodynamic lift generates the force needed for planes to fly. -- By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate explanations still circulate today. So, where did Einstein go wrong? And how exactly do planes fly? Raymond Adkins explains the concept of aerodynamic lift. Lesson by Raymond Adkins, directed by Michael Kalopaidis, Zedem Media.

    Can a black hole be destroyed? - Fabio Pacucci

    Are black holes indestructible? Explore the theory of Hawking radiation, a process that could lead a black hole to gradually lose mass and evaporate. -- Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes. But is there any way to destroy a black hole? Fabio Pacucci digs into the possibility.
