Scientists are now able to collect and analyze DNA pulled from thin air, and the groundbreaking new techniques used to do it could transform the way endangered animals and natural ecosystems are studied and protected.
Two groups of researchers working independently, one based in Denmark and the other in the UK and Canada, tested whether airborne DNA could be used to detect different animal species by collecting samples in Denmark and in the UK.
While the two research teams used different methods to filter the DNA from air -- both were successful in identifying the animals lurking nearby.
