This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.

A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.

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 a region of the brain called the cerebral cortex develops in a human fetus.

This video shows a technique used to obtain detailed images of nerve cells by fluorescent microscopy.

Dr. Jason Biggs of the University of Guam Marine Laboratory discusses the anatomy of cone snails and introduces us to a variety of cone snail species with different tactics to hunt and capture their prey.

This animation shows how the drug Prialt suppresses signals from the nervous system, which can paralyze certain organisms.

This animation shows how cone snail toxins cause paralysis by blocking signal transmission at the synapse between neuron and muscle.
