This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

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.

This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.

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.

This film explores how mutations in gene regulatory regions have resulted in major changes in the anatomy of freshwater populations of stickleback fish.

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

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

This film explores the genetics and evolution of lactase persistence in humans.

This animation shows how a variety of proteins interact to regulate the transcription of eukaryotic DNA into RNA.

This animation explores the LUX operon, a set of five genes that are involved in bacterial bioluminescence.
