In 2015, the air force, the United States began developing a laser weapon that is mounted on the vehicle and neutralizes explosive mines at a distance. But before you disarm a hidden underground ammunition, they must first be detected. At the moment this involved specially trained dogs or soldiers with metal detectors, each time putting their lives in mortal danger. To save people and animals from the risky jobs, the American company Raytheon began developing genetically modified bacteria, capable of finding mines and to signal their whereabouts with a bright glow.
About the new invention, the company said in its blog. She has already signed a contract with the office of DARPA, which oversees research projects of the Ministry of defense. In the development of genetically modified microorganisms help her researchers from the Worcester Polytechnic Institute (USA). What mines will be able to detect the bacteria is still unknown, but the developers have shared how they work.
Bacteria for the detection of explosives
The researchers intend to create two groups of bacteria that will be sprayed over the areas with possible presence of mines and to work together. The first group of microorganisms to be modified in a way to penetrate deep into the soil and, in the case of explosives detection, to report the presence of a second group of bacteria. She, in turn, will Shine brightly so that the place of discovery of mines were seen flying drones. Then the mine will be engaged or received the exact coordinates of the engineers or armed aircraft, or robotic engineers.
Also details of new technologies shared by the head of the research group Allison Taggart. According to her, they already know that bacteria can be trained to detect mines which are part of the explosive substances. But under the ground to look for them much harder, and at the moment they are looking for a way to transport bacteria at a greater depth. They also have to teach the second group of bacteria to glow so bright to be seen even from a great height.
In theory, detection of mines in future could help in the search for buried under ground debris. You can also assume that the bacteria may become an indispensable tool of archaeologists. For example, by making some changes in their genes, you can certainly discover old buildings or bones that lived thousands and millions of years ago ancient animals. If fossilized bones is not, then a lot of interesting things about the ancient inhabitants can be learned and thanks to the traces left by them.
