DARPA is embarking on an undersea submarine detection system so weird it may just work. The Pentagon’s research and development arm wants to learn the behaviors of undersea animals including fish, shrimp, and microscopic phytoplankton so it can use them to detect manned and unmanned submarines passing by. Such a network would enhance the U.S. military’s ability to detect even the quietest... [Read More]
