Last year, researchers at the Massachusetts Institute of Technology (MIT) made the first sustained flight of a heavier-than-air aircraft with no moving parts. It was propelled by electroaerodynamic propulsion, which requires no moving parts and was, by many definitions, the first ever solid state flight. This article explains exactly how it works and what the
As the military, science agencies, and communications firms compete for scarce spectrum resources, researchers at Harvard, MIT, and the Army have developed a compact, room temperature, widely tunable terahertz laser that offers the potential for high-bandwidth communications, ultrahigh-resolution imaging, and precise long-range sensing for radio astronomy. Until now, the terahertz section of the electromagnetic spectrum,
Next-generation algorithms and sensors for detecting chemical threats put through their paces in SIGMA+ program. May hold promise for military use in development of large region scale chemical, biological, radiological, nuclear, and explosive threat threat detection networks. DARPA’s SIGMA program, which began in 2014, has demonstrated a city-scale capability for detecting radiological and nuclear threats
