This video follows an international team of researchers as they collect data to map migratory bird populations in the US and Mexico.

This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

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

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 describes how only a small part of the human genome directly codes for proteins.

This animation shows how the Human Genome Project sequenced the human genome, which contains over 3 billion nucleotides.

This animation illustrates Sanger sequencing, one of the earliest methods used to sequence DNA.
