Genetic Mutations and Disease

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.

Interactive Assessment for The Day the Mesozoic Died

Several questions are embedded within the short film The Day the Mesozoic Died, which tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

Learning from Past Extinctions

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.

The Eukaryotic Cell Cycle and Cancer

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

From Cancer Genomics to Cancer Drugs

In this talk, biomedical scientist Charles Sawyers discusses how genetic data reveal common mutations in cancer and can help uncover shared genetic mechanisms among different cancer types.

Symbiotic Bioluminescence

This tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

Bacterial Quorum Sensing

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

Electrical Activity of Neurons

This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.

Cells of the Immune System

This tutorial provides an overview of the immune system, concentrating on the roles played by B and T lymphocytes, and on the antigen-presentation system.

Neurophysiology Virtual Lab

This interactive, modular lab explores techniques for identifying and recording the electrical activities of neurons, using the leech as a model organism.
