Citric Acid Cycle

This animation shows the reactions of the citric acid cycle, which splits off carbon atoms and generates energy-rich reduced forms of cofactor molecules. It is the first of three animations about cellular respiration.

ATP Synthesis

This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the third of three animations about cellular respiration.

Electron Transport Chain

This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.

Biology of SARS-CoV-2

This three-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

Mystery of the Buffalo Boom

In this video, ecologist Tony Sinclair takes us through the steps of how he uncovered that the eradication of an infectious disease in cattle led to a boom in the Serengeti’s buffalo and wildebeest numbers.

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.

Fecal Microbiota Transplants

This short video explores the science behind fecal microbiota transplants, a method of transplanting stool from healthy donors to sick patients to treat certain diseases.

The Search for a Mutated Gene

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.

Genes as Medicine

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.
