New York air to have its genes sequenced

"According to Venter, siphoning off vats of smoky New York City air each day and amplifying the DNA of the fungi, bacteria and viruses it contains is the only way to uncover the mysteries of airborne microbial life. Only 1% of the microbes in the air can be identified by growing cultures in the lab, he told the New York Times, yet 'it is important to understand this unseen world'." (Via The Anomalist.)
