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.

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.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This animation shows how varying concentrations of a signaling molecule activate different transcription factors to determine cell fate.

This animation shows how stem cells from early mammalian embryos can be grown and studied in a laboratory.

This animation describes the formation and fates of the three germ layers in a human embryo.

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

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