Scientists want to track the world's biodiversity using DNA in the air

Scientists are pioneering a groundbreaking method to track biodiversity by extracting DNA from air samples collected across entire countries. This innovative approach allows for cost-effective monitoring of species populations and provides insights into how these ecosystems change over time. Beyond ecological studies, the technique has potential applications in environmental health, such as detecting disease spread or tracking agricultural pests, offering a versatile tool for conservation and global monitoring efforts.
