USA: DNA sucked into air filters can reveal what plants and animals are nearby
NEW YORK (AP) — 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.
The method could help solve the tricky challenge of keeping tabs on biodiversity, according to a study published Monday in the journal Current Biology.
