But when he cut parts off or even split it in two, it regenerated, which was decidedly plant-like. So, what was this miraculous creature? Raymond Adkins explores the near-immortal biology of the hydra. Lesson by Raymond Adkins, directed by Sharon Colman.

Why is Queen Victoria so controversial? - Carolyn Harris

Why is it so easy for birds to spread illness? - Benjamin Anderson

17 sept 2026

Dig into the science of avian influenza to find out what makes the H5N1 virus so dangerous, and its potential to jump to humans. -- While avian influenza used to infect mostly birds, in the past few years, it’s been found in over 70 mammal species, including cats, dairy cows, foxes, seals, and bears. Each new mammalian infection gives the virus more chances to drift or shift, spill over into humans, and ignite a pandemic. So, what is it about H5N1 that makes it so frighteningly flexible? Benjamin Anderson investigates. Lesson by Benjamin Anderson, directed by Anton Bogaty.

10 sept 2026

Dig into the neuroscience behind our sense of direction and find out why some people are better at navigating than others. -- Whether you identify as a wayfinding whiz or get lost returning from the grocery store, your brain has a built-in navigation system that facilitates spatial skills, from sensing which direction is north to map-reading and route-learning. So, why do we still struggle to find our way? And why do some of us find ourselves lost more often than others? Oliver Baumann digs into our sense of direction.

What are tariffs, and how do they work?

3 sept 2026

Explore how tariffs work and dig into how their enactment can set off an economic chain reaction that impacts global trade. -- In 1930, in hopes of supporting farms and manufacturing, President Hoover made a bold decision: he approved a sweeping 20% tax on all imported agricultural and industrial goods. But the plan completely backfired, leading exports to fall and global trade to decline. And it wouldn't be the last time a world leader was shocked by a tariff’s consequences.

25 ago 2026

Dig into Plato’s infamous Ship of State thought experiment, which explores how democratic societies handle leadership and power. -- Imagine a ship struggling in an endless storm.
