When a roadside bomb or other explosive device goes off, it hits everything nearby with an extreme blast of pressure. Almost simultaneously comes a heat--more than 1,000 degrees Fahrenheit--that's hot enough to cook skin. Presented today at a meeting of the American Chemical Society, a new invention will try to counteract that, and do it through a technology that's already been used for hundreds of years: camouflage paint.
3-D printing has yielded items both fascinating and potentially troubling. Now we can add one more to the list of printed achievements: The U.S. Army has had a rapid prototyping wing for some time, and now they've deployed full teams--complete with scientists and 3-D printers--to Afghanistan.
The majority of engineers are men. The majority of U.S. Army soldiers are also men. So when a new piece of equipment is being designed--equipment that could change the outcome of a life or death situation--it's made with men in mind. Then, if women need it, they might just have to shoehorn themselves into the male variety, as is currently the case with body armor. But the Army recently announced it'll try to change that by testing new body armor built for women.
