Progress sometimes causes chance, work sometimes and imagination to all. Bacteria-driven submarines, for example, will soon jump from movies to reality. Researchers at Utah State University have announced that at least for a few months the prototype will be possible. The idea is simple: as shown in the image, it is about taking advantage of the movement of flagellated bacteria to induce mechanical strength and subflap.

At first all the bacteria will be placed in the propeller blades, but from that moment only the scourge is wanted. If achieved, it would be possible to build structures around 100 nanometers that could enter the veins, detect and destroy tumors, as well as open blocked veins. For the moment, while a more suitable rower is found, Salmonella works with a strain of the bacteria Typhimurium and in a year begin to build millimetric robots.
