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 video describes the case of a patient with retinitis pigmentosa (RP), a progressive disease that leads to blindness, and how physician-scientist Dr. Ed Stone approached the search for the causal mutation.

This film describes the scientific principles and the research efforts involved in the development of a gene therapy for a congenital form of blindness, and how a young patient benefited from this medical breakthrough.

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

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.

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

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

This animation shows how genes associated with autism affect the structure and function of neuronal synapses.

This video tells the story of a boy with a congenital brain condition and how analyzing samples from him and other patients helped discover the genetic cause.

In this talk, biomedical scientist Christopher Walsh discusses how DNA sequencing technology has led to a better understanding of the genes involved in brain development.

In this talk, biomedical scientist Charles Sawyers discusses how understanding the mutations that cause cancer can guide the development of targeted drug therapies.
