Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

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.

Root Movement

This activity explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

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.

How We Get Our Skin Color

This animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

Synchronized Division

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

HIV Life Cycle

This animation shows how HIV infects a cell and replicates itself using reverse transcriptase.

Planarian Regeneration and Stem Cells

This video discusses the remarkable regenerative capabilities of the planarian, and how biologist Alejandro Sánchez Alvarado uses them to study the biology of stem cells.
