Gizmodo reports that researchers looking into bizarre reports of U.S. diplomatic staff in Cuba and later China hearing troubling noises have pinned the most likely cause. They say it’s not some form of mysterious sonic device, as previously speculated. The noises led to a developing of symptoms very similar to brain trauma.
Instead, according to a report in the New York Times on Saturday, they have increasingly become convinced that unknown parties attacked the staff with some sort of microwave radiation emitter. It was possibly one small enough to truck around in a van.
