Glowing engineered bacteria point out explosive landmines

New molecularly engineered E. coli bacteria emit a bioluminescence visible to the naked eye, enabling detection of landmines from afar.

Researchers who discovered how to utilize fluorescent E. coli bacteria to locate landmines have recently further mutated them so that they are now both more sensitive and emit a glow visible to the naked eye, eliminating the need to scan the ground using laser light beams.

In 2017, researchers from the Hebrew University of Jerusalem molecularly engineered E. coli to emit a fluorescent light upon coming in contact with explosive vapors accumulated in the soil above landmines. This light was recorded using a laser-based scanning system so the mines could be located safely from afar.
