A quarter of a teaspoon of VX nerve agent (“one of the deadliest chemical agents ever created,” according to the video above) disappeared from a Utah military research base earlier today. Over 1,000 people at the base were locked inside the facility during a search for the missing chemical weapon, which was found “early on Thursday.” A press conference is scheduled for later today.

From Wikipedia:

VX is the most toxic nerve agent ever synthesized for which activity has been independently confirmed. The median lethal dose (LD50) for humans is estimated to be about 734 micrograms through skin contact and the LCt50 for inhalation is estimated to be 30-50 mg·min/m³.
