Crash Course Astronomy Marathon • Full Series

In Crash Course Marathons, we’re revisiting the series you love, in long-form videos that cover entire subjects from back to front. Crash Course Astronomy covers outer space, from the stars and nearby planets we can see with the naked eye, to the mysterious dark matter no one can see at all. With detours to exoplanets, deep time, and even our own planet Earth, we’ll explore the universe — what we know, how we know it, and what’s still left to discover.

Everything you need to know about bird flu - Benjamin Anderson

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.
