Winogradsky Column: Microbial Ecology in a Bottle

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

Interactive Assessment for The Birth and Death of Genes

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

Vertebrate Circulatorium

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

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.

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.

Symbiotic Bioluminescence

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

Cardiology Virtual Lab

This interactive, modular lab explores the tools that doctors use to examine and diagnose patients with heart conditions.

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.
