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.

How We Get Our Skin Color

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

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.

Mutations in Cancer

This video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.
