英國及丹麥研究團隊研發出從空氣採集DNA的方法，並於動物園內進行測試。他們成功採集到各種動物的DNA，包括哺乳類、鳥類、爬行類甚至池裡的魚類。雖然未能探測到DNA釋放的時間，亦未能計算於空氣中的存活期，但相信這技術能在更有彈性及減少干擾的情況下採集動物DNA。
British and Danish research groups discovered a way to detect DNA from the air and tested it in a zoo. They were able to found DNA of different animals including mammals, birds, reptiles and even fish in the pond. Even though they are not able to detect the releasing time of the DNA, and not able to know how long it survives in the air, but this discover will help to detect animal presence in a more flexible and less disturbing way.
