Bacteria and lasers can detect landmines
Buried landmines can now be detected using bacteria engineered to sense explosive vapors, according to a new study in Nature Biotechnology.
Why it matters: There were more than 6,000 landmine-related casualties recorded in 2015. One of the biggest challenges in clearing landmines is finding them. Bacteria — along with plants and animals — have been proposed for detecting undetonated devices before, but this is the first demonstration of how bacterial sensors might work in the field.
