Depressingly, Mother Jones already created a map of mass shootings in America the last time we had one, so it was all ready to go when news of this morning's shooting in a Connecticut elementary school broke. By their tally, there have been 61 mass murders in the past 30 years. It's important not to forget them. See the map here.
We've already seen that it's possible to print parts of a gun--and have it work--using a 3-D printer. The project was highly controversial, but now a group wants to make sure that anyone can print a working gun at home.
Get ready. It's now possible to print weapons at home.
An amateur gunsmith, operating under the handle of "HaveBlue" (incidentally, "Have Blue" is the codename that was used for the prototype stealth fighter that became the Lockheed F-117), announced recently in online forums that he had successfully printed a serviceable .22 caliber pistol.
Despite predictions of disaster, the pistol worked. It successfully fired 200 rounds in testing.
When a bullet is recovered at a crime scene, ballistic identification can help track the gun that fired it, but identifying the person who fired the gun is a lot harder. Now scientists have found an unlikely method to ID gunmen on the lam, using flower pollen.
When you don’t have an advanced flying spy drone, launching a wireless camera 500 feet into the air could be your best option. But most people, even in law enforcement, don’t have access to 40mm grenade launchers, the logical choice for such a task. How about using a flare gun instead?
When you’re aiming at a target two miles away, the slightest perturbation could end up causing a catastrophic miss — not good enough for today’s military. Until guns can aim themselves, snipers need the most accurate weapons possible. Engineers at Oak Ridge National Laboratory came up with a laser-guided correction system that ensures a shooter’s crosshairs are always on the mark.
The new Reticle Compensating Rifle Barrel Reference Sensor measures slight disruptions in a gun barrel, automatically compensating for how they would impact a bullet’s trajectory and adjusting the gun’s crosshairs accordingly.
Northrop's heavy-duty hauler CaMEL has been a success, scoring contracts from Israel and serious interest from the U.S. Army. But why haul miscellaneous stuff when you can haul a giant gun instead?
The hauler is named the Carry-all Mechanized Equipment Landrover--yeah, that spells out CaMEL. It's a 60-inch-tall treaded vehicle capable of carrying an impressive 1,200 pounds of stuff, and its usefulness in the field is proven by its popularity. Israel has bought more than 60 of them, and the U.S. Army is looking into its possibilities as well.
The Stingray, the military’s newest bomb-fighting tech, is a small water gun developed by Sandia National Laboratories and a firm called TEAM Technologies. Far from dousing roadside bombs with water, it uses an ultra-high-pressure water beam to slice through steel, ripping bombs open before they can harm troops. Watch below as a propane tank meets an untimely end.
U.S. Army Special Forces soldiers will deploy with the XM-25 weapon this summer, so that they can shower enemies hidden inside buildings with lethal smart rounds. Veterans of the Afghanistan conflict who tried the weapon predicted it would be a "game changing" gun capable of taking out insurgents hidden behind cover, Military.com reports.
The XM-25 resembles a highly sophisticated grenade launcher that fires laser-guided smart rounds. The laser gauges a distance to target and allows the warfighter to set where the round will detonate, adding or subtracting increments of 3 meters from the laser-spotted point. Then the scope tells a microchip inside the round how far it should travel before exploding.
Between the yelling of sergeants, the rumble of jet engines, and the deafening pop of gunfire, a soldier's sense of hearing rapidly deteriorates in the heat of battle. Luckily, the Dutch company Microflown has designed a special microphone that can do a soldier's listening for him. By measuring the mechanical movement of individual air particles, as opposed to sound waves as a whole, the device can not only pinpoint the origin of sniper fire or approaching aircraft, but detail their make and model, as well.
Say the word "toy" to a techie, and his mind will think one thing: robots. But all infrared-loving, artificially-intelligent smart-toy-ogling tech-savvy aside, new toys can instill as much "ooh! shiny!" as even the hottest cellphone. And we're not just talking about robots: This week, the International Toy Fair hit NYC, and PopSci.com found 20 funky new toys with a few tricks up their sleeves.
Military and police higher-ups can now see just how many shots a particular weapon fired during the course of a battle or incident. The Register reports that a new black box device designed for rifles and submachine guns could report on ammo usage and weapon jamming, as well as who shot whom at what time.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
