  • Why do cockroaches prove so hard to kill? - Ameya Gondhalekar

    Dig into the genetic adaptations of cockroaches, and find out what makes it so hard to get rid of these tenacious creatures.

    --

    In ancient Egypt, there was a spell that declared, “Be far from me, O vile cockroach.” Thousands of years later, we’re still trying to oust these insects. But from poison traps to brandished slippers, cockroaches seem to weather just about everything we throw at them. So, what makes cockroaches so hard to kill? Ameya Gondhalekar digs into the genetic wonders of this troublingly tenacious creature.

    Lesson by Ameya Gondhalekar, directed by Irida Zhonga.

    In order to visualize and dramatize the lives of these fascinating creatures, the artists have chosen to playfully anthropomorphize cockroaches. In real life cockroaches don’t dine like humans, go shopping for organic matter, and most unfortunately, don’t wear lederhosen (at least, to the best of our knowledge).

  • The 3 top forecasters of how well you'll age - Juulia Jylhävä

    Explore how our bodies change and age over time, and the three common markers scientists use to measure aging.

    --

    If you want to learn a tree’s age, you can count their rings. When it comes to humans, scientists have yet to find any visible traits that mark our age with the same specificity. But in the past few decades, they’ve discovered small, invisible markers hidden within the body that do change over time. Juulia Jylhävä shares what these markers can tell us about our health, history, and future.

    Lesson by Juulia Jylhävä, directed by Flaka Kokolli, Diellza Franca, Flammorum Animation Studio.

  • How does artificial intelligence learn? - Briana Brownell

    Explore the three major methods of machine learning, which allows computers to write their own rules to problem solve and process data.

    Uploaded 11-03-21

    --

    Today, artificial intelligence helps doctors diagnose patients, pilots fly commercial aircraft, and city planners predict traffic. These AIs are often self-taught, working off a simple set of instructions to create a unique array of rules and strategies. So how exactly does a machine learn? Briana Brownell digs into the three basic ways machines investigate, negotiate, and communicate.

    Lesson by Briana Brownell, directed by Champ Panupong Techawongthawon.

  • Watch this if you fear snakes - Andrew Whitworth

    Travel around the world to visit some of nature’s most incredible snakes: vipers, and find out which are the most dangerous.

    --

    As of 2021, there are 368 species of viper worldwide. The name comes from the term viviparity, which means giving birth to live young. Vipers are often highly venomous, with two hollow, extra long fangs that unfold into imposing weapons when the viper prepares to strike. So, which are the most dangerous? Andrew Whitworth travels around the world to visit some of nature’s most incredible snakes.

    Lesson by Andrew Whitworth, directed by Billie Baxter.
