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

DNA is all around us — even in the air we breathe. Now scientists have found that air quality monitoring stations — which pull in air to test for pollution — also pick up lots of DNA that can reveal what plants and animals have been in the area.

Britain’s fertility regulator on Wednesday confirmed the births of the U.K.'s first babies created using an experimental technique combining DNA from three people, an effort to prevent the children from inheriting rare genetic diseases.

Scientists who tracked humpback whales in Australia noticed that fewer whales wailed to find mates as their population grew.

Scientists have uncovered new clues about a curious fossil site in Nevada, a graveyard for dozens of giant marine reptiles.

Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland.

From South Dakota and Oklahoma to Alaska and Alberta, Indigenous groups in the U.S. and Canada are leading efforts to restore bison across North America.

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.

Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one.

This animation shows two examples of how the cell uses energy from ATP. It is the sixth of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.
