US Navy biologists creating GM bacteria capable of detecting enemy ships and submarines.

US Naval Research Laboratory (Naval Research Laboratory, NRL)  has  allocated $ 45 million for the implementation of a program to study the prospects for the use of genetic engineering for the navy. Part of the program was the development of genetically modified microorganisms capable of detecting the presence of enemy ships, submarines, underwater drones and divers. About this Defense One told Sarah Glaven (Sarah Glaven), a researcher from the NRL.


We are talking about the use of normal, widespread in the ocean, floating bacteria and unicellular algae, primarily – proteobacteria Marinobacter. Their genome is planned to be “supplemented” so that they react to the appearance in the water of traces of exhaust diesel engines, rare metals and other substances accompanying the ships. For example, it is possible to force microorganisms to pump electrons from cells under the action of these substances, and then to register them using small underwater drones.


“Then you can start imagining that you can create an electrical signal when the bacteria encounters some molecule in their environment,” NRL researcher Sarah Glaven said at a November event put on by the Johns Hopkins University’s Applied Physics Lab.
“The reason we think we can accomplish this is because we have this vast database of info we’ve collected from growing these natural systems,” she further articulated. “So after experiments where we look at switching gene potential, gene expression, regulatory networks, we are finding these sensors.” She said that hard evidence that this sort of biotechnology breakthrough is possible and capable of being used to serve the military is about a year away


It is worth noting that the NRL project is far from the first attempt to create “living sensors” from GM organisms. And although it is not a big problem to obtain and demonstrate their performance in the laboratory, it is not yet possible to consistently reproduce these results “in the field”. Organisms, burdened by additional biochemical mechanisms, are worse adapted for survival in the environment and competition with their “normal” counterparts.


According to another scientist from the NRL, Dimitra Stratis-Cullum (Dimitra Stratis-Cullum), quoted by Defense One, for this, the GM marinobacterium is planned to be enclosed in a protective capsule, which should prolong their survival in the natural environment until a suitable time. Perhaps it will be applied immediately before the launch of such “live sensors” in the case. However, all these works, as acknowledged by NRL developers, remain only at the very early stages of research.


The US is once again in an age of great power competition, according to the 2018 National Defense Strategy. It faces new threats from adversarial powers like China and Russia beneath the waves. “In the undersea domain, the margins to victory are razor thin,” Adm. James G. Foggo III, the commander of US Naval Forces Europe-Africa, told Pentagon reporters in October.
