This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This film explores the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.

This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.

This film describes the scientific principles and the research efforts involved in the development of a gene therapy for a congenital form of blindness, and how a young patient benefited from this medical breakthrough.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This video shows real footage of somatic cell nuclear transfer (SCNT) being performed on eggs.

This animation gives an overview of how a fertilized human egg develops into an embryo.

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

This animation shows how zebrafish can rapidly heal wounds to the heart.

This animation shows how somatic cell nuclear transfer (SCNT) creates an embryo from an egg cell and a body cell.

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

This video shows real footage of courtship behavior of fruit flies with wing spots.
