Forget fingerprints, strands of hairs and saliva swabs - scientists have now come up with a way of detecting even the smallest traces of DNA in the air. A new technique that detects DNA fragments in the air could help forensic investigationsProfessor Elizabeth Clare of York University, Canada, tested out the innovative technique last December at Hamerton Zoo Park in Cambridgeshire. The scientists believe this was down to how active the animals were, with the lemurs shedding more DNA as a result. Scientists have now found a way of collecting DNA from the air in a room. For example, studying the air of a tomb may be a way to obtain DNA samples of long-dead mummies or skeletons.
