Guns

For people such as soldiers, security officials and airport workers, drones aren't always a welcome sight. That's why drone-jamming guns were developed, and the new Paladyne E1000MP "pistol" is said to be one of the most compact on the market.

The Trijicon Ventus looks like a set of binoculars, but in actuality it's the world's first hand-held device capable of providing three-dimensional wind data at multiple points between a shooter and a target up to 500 yards (457 m) away.

Turkey is preparing to receive its first shipment of armed multicopter drones this month. Made by the country's own Asisguard, the Songar drone can carry 200 rounds of ammo, and can fire with precision from 200 yards thanks to its anti-recoil system.

CCTV systems may help security personnel watch for handguns in places such as airports, but the task of manually scrutinizing every person on every screen is still a daunting one. It was with this in mind that researchers recently developed a system that automatically recognizes guns on video.

With the prospect of robot police officers hitting our streets, it's worth taking a moment to look at the current state of affairs, where we're headed, and whether it's a good idea to give robots guns.

A team of scientists at Flinders University in Australia have developed a new technique for analyzing gunshot residue that is so sensitive that it's possible to match residue with a specific brand of ammunition.

​While most of us may just associate mistletoe with Christmas parties, the fact is that the parasitic plant can be a nuisance in the wild. That's why scientists are taking the offensive, with a system that shoots herbicide up into trees' high branches.​
