This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This short video explores how the symbiotic relationship between certain plants and fungi allows these organisms to survive in very hot temperatures.

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

This video describes the work of biologists Steve Palumbi and Megan Morikawa, who use field and controlled experiments to understand the mechanisms that allow some corals to tolerate a greater amount of heat stress than other corals.

In this talk, biologist Anthony Barnosky discusses Earth’s five mass extinctions and whether current species declines may be part of a sixth mass extinction.

In this talk, marine biologist Stephen Palumbi discusses how coral reefs are threatened by climate change and how to protect them.

This video follows biologist Liz Hadly in Yellowstone National Park as she discusses how ecosystems are threatened by warming temperatures.

This video describes how prehistoric extinction rates are calculated from fossil data in a paleodatabase and compared to modern extinction rates.

This animation zooms into a coral reef to explore the tiny animals that build reefs, the photosynthetic algae inside their cells, and the damaging process of coral bleaching.

This film tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

This animation provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.
