Uriminzokn.
Korean for “our nation.” It’s the Twitter handle for a shadowy North Korean government agency called Uriminzokkiri, which is using modern social media to spread cold-war-grade agitprop.

Chemical cartographyn.
Mapping a city’s distinctive smells to create a baseline for olfactory detection of suspicious activities—like bomb production. Funded by Darpa, chemical cartographers are recording the signature stench of businesses, from gas stations to dry cleaners.

Metaflexn.
Flexible fabric for invisibility cloaks. An ultrathin lattice of gold, Metaflex can channel light around objects, hiding them from sight—even if they’re moving. At 40 square millimeters or so, the prototype swatches are about large enough to cloak an insect.
