Population Dynamics

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

Survey Methods

This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.

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.

BCR-ABL: Protein Structure and Function

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

Gorongosa Timeline

This interactive timeline explores the history of Gorongosa National Park in Mozambique.

BCR-ABL

This model shows the structure of the protein BCR-ABL, which causes a type of cancer called chronic myeloid leukemia.

Gleevec-Resistant BCR-ABL

This model shows a mutated form of the cancer-causing protein BCR-ABL that is resistant to the drug Gleevec.

Adenosine Triphosphate (ATP)

This model shows the structure of ATP, a molecule that provides energy for cellular processes, including protein phosphorylation.

Paleoclimate: A History of Change

This interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

Geological History of Oxygen

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.

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.
