China’s military is leading the world in brain ‘neurostrike’ weapons: Report
China’s People’s Liberation Army is developing high-technology weapons designed to disrupt brain functions and influence government leaders or entire populations, according to a report by three open-source intelligence analysts.
A phaser weapon is not fictional. It is basically laser technology using amplified sound waves, instead of light waves. Been around since the 1960's. The "ph" in PHaser represents "phonon" (sound wave-particle) instead of the "L" (stands for light) in Laser.
Of course, the idea of the Star Trek phaser is fictional, but the technology it is based on is not.
