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.

How Animals Use Sound to Communicate

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

Sampling and Normal Distribution

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

Vertebrate Circulatorium

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

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.


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.

Symbiotic Bioluminescence

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