Why Two Heads?

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

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.

Synchronized Division

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

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.

Salamander Limb Regeneration

This animation shows how salamanders can replace missing limb tissues with the help of cells similar to stem cells.

X Inactivation

This animation shows how X chromosomes are randomly switched off in most female mammals.

VEGF

This animation shows how tumors use the protein VEGF to recruit blood vessels.
