In a first, scientists have revealed that animal and human DNA can be plucked straight out of thin air. The development heralds a promising new scientific technique with possible applications for ecology, forensics, and medicine, according to a new study.

“For example, this technique could help us to better understand the transmission of airborne diseases such as COVID-19.”

The research team is working with partners in industry, including the company NatureMetrics, to see how the technique can be applied in other ways, the university said.
