Fishing for DNA – how a cup of river water can reveal secrets about human health, pollution and biodiversity

Scientists are now using a groundbreaking method called environmental DNA (eDNA) to gather critical data from just a small sample of water, sand, or air. This technique can detect the presence of humans, wildlife, and even pathogens, providing invaluable insights into migration patterns and health issues. The implications are vast, as eDNA can also reveal pollution levels and biodiversity changes, making it a powerful tool for environmental monitoring and conservation efforts. This innovative approach is reshaping how we understand and protect our ecosystems.
