The US military has issued $4 million in grants to university researchers to study ways to read people’s thoughts. According to the Associated Press, the military says the research could someday lead to a gadget capable of translating the thoughts of soldiers who suffered brain injuries in combat or even stroke patients in hospitals. But critics say such mind-reading technology could be used during interrogations. The project is a collaboration among researchers at the University of California, Irvine; Carnegie Mellon University; and the University of Maryland.
