Look back: U.S. withdrawal from Vietnam 20 photos While the fall of Saigon two years later is remembered as the final day of the Vietnam War, many had already seen their involvement in the war finished -- and their lives altered -- by March 29, 1973.U.S. soldiers leaving the country feared angry protesters at home. North Vietnamese soldiers took heart from their foes departure, and South Vietnamese who had helped the Americans feared for the future.Many veterans are encouraged by changes they see. The U.S. has a volunteer military these days, not a draft, and the troops coming home aren t derided for their

Human skin may very well be one of the world most impressive sensor arrays. Able to detect temperature, pressure, touch and pain simultaneously, your skin sensory receptors feed you a constant data stream about the environment around you. Now, research

stanley mug nology senses touch, humidity and temperature simultaneously, with touch sensitivity 10 times greater than current e-skins. Technion system uses a network of interconnected gold nanoparticles 5-8 nanometers in diameter, laid over a base of flexible polyethylene terephthalate soda bottle plastic , to measure changes in the environment. Bending the e-skin, for example, brings the nanoparticles closer together or farther apart, changing the electrical conductivity between them. The scientists are able to change the material sensitivity by altering the thickness and construction of the base layer, enabling strain or crack detection in a variety of industrial applications. Stanford Develops Nanotube-Infused Artificial Skin for Robots and People Alike Of course, the most exciting potential application is prosthetics, where touch and temperature sensitivity could could for the first time offer skin-like sensation. Paired with next-generation prosthetics that more closely mimic natural human hardw
