    The remarkable reason zebras have stripes - Cella Wright

    Dig into the scientific theories of why zebras have stripes, and why this unique patterning sets them apart from their equine relatives. -- Zebras belong to the same equine family as horses and donkeys. After their lineage entered Africa, they evolved into three zebra species, lived in social herds, grazed on grasses, and evaded fierce predators. One mystery that has perplexed prominent scientists for decades is the matter of their coats: why are they striped? Cella Wright digs into the common theories about the unique patterning.

    Can AI foresee someone's breakup? - Thomas Hofweber

    Explore one of the main issues of AI-based predictive models and how it affects user decision-making and accountability. -- A couple has been considering getting engaged, but they’re worried about divorce statistics. An AI-based model was just released that can predict your likelihood of divorce with 95% accuracy. The only catch is the model doesn’t offer any reasons for its results. So, should they decide whether or not to get married based on this AI’s prediction? Thomas Hofweber explores AI’s transparency problem. Lesson by Thomas Hofweber, directed by Hannah Lau-Walker. This video was produced in collaboration with the Parr Center for Ethics, housed within the renowned Philosophy Department at the University of North Carolina at Chapel Hill.

    How do animals rebuild their limbs? And why can't humans do it? - Jessica Whited

    Explore the incredible regenerative capacity of salamanders, and see how they’re able to regrow limbs, hearts, and even brain tissue. -- For some animals, losing a limb is a decidedly permanent affair. But for salamanders, particularly axolotls, amputation is just a temporary affliction. Not only can they grow back entire limbs in as little as six weeks, they can also regenerate heart and even brain tissue. So, how does this astonishing adaptation work? Jessica Whited explores the incredible regenerative capacity of salamanders. Lesson by Jessica Whited, directed by Anton Bogaty.
