The Science of an Extreme Animal Athlete

This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

Scientists rethink Alzheimer’s, diversifying the drug search

When researchers at the University of Kentucky compare brains donated from people who died with dementia, very rarely do they find one that bears only Alzheimer’s trademark plaques and tangles — no other damage. That hard-won lesson helps explain how scientists are rethinking Alzheimer’s.

Photosynthesis

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

Cystic Fibrosis Mechanism and Treatment

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.

Science Says: Unavoidable typos in DNA help fuel cancer

Cancer patients often wonder “why me?” Does their tumor run in the family? Did they try hard enough to avoid risks like smoking, too much sun or a bad diet? New research suggests random chance may play a bigger role than people realize.

Gorongosa's Water Cycle

This animation illustrates the main stages of the water cycle in Gorongosa National Park, an ecosystem that experiences both wet and dry seasons.

How We Get Our Skin Color

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

The Biology of Skin Color

This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

Seeing Single Molecules Move

This animation shows how transcription factors find their binding sites in real time. It is based on data from an imaging method that can track single molecules in a living cell.

Coral Bleaching

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.
