Counting Species out of Thin Air

The video discusses the final maneuver of a space telescope and introduces the concept of environmental DNA (eDNA), which allows scientists to detect animal species by measuring DNA in the air. Two studies in European zoos successfully identified various species, including endangered ones, using this method. The video highlights the potential of eDNA for conservation, offering a non-invasive way to monitor ecosystems. Additionally, a well-preserved theropod embryo was discovered in China, providing insights into dinosaur development and their relation to modern birds.
