Scientists Show You Can Collect DNA From The Air

Scientists and investigators might not need to scoop up DNA from surfaces in the future. According to Science Focus, researchers at the Queen Mary University of London have shown that you can collect “environmental DNA” (eDNA) from the air.

The Scientists used a peristaltic pump combined with pressure filters to grab samples of naked mole rat DNA for five to 20 minutes, and then used standard kits to find and sequence genes in the resulting samples.

This method not only pinpointed the mole rats’ DNA (both in their housing and in the room at large), but caught some human DNA at the same time.

Lead author Dr. Elizabeth Claire said the work was originally meant to help conservationists and ecologists study biological environments. With enough development, though, it could be used for considerably more.
