This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

This film explores the species-area relationship, a general ecological rule that describes how the number of species in a habitat changes with area, and shows how it has been applied to the conservation of protected areas.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This video describes the case of a patient with retinitis pigmentosa (RP), a progressive disease that leads to blindness, and how physician-scientist Dr. Ed Stone approached the search for the causal mutation.

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 describes the process by which a line of genetically modified mosquitoes was engineered to reduce populations of wild mosquitoes.

This video follows the work of scientists conducting the first census of African savanna elephants in over 40 years and the methods they are using to obtain accurate, up-to-date numbers across the continent.

This video introduces the concept of niche partitioning with examples drawn from the African savanna.

This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

This video describes the cutting-edge method of DNA metabarcoding and how it is used to study how animals partition resources in a shared habitat.
