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

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.

This animation shows how transcription factors find their binding sites in real time. It is based on data from an imaging method that can track single molecules in a living cell.

This video shows a technique used to obtain detailed images of nerve cells by fluorescent microscopy.

This video explores how advances in DNA sequencing technology have improved cancer diagnosis and treatment.

This animation describes PCR, a standard laboratory technique for making many copies of a specific DNA sequence.

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

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