A new MIT technology is shedding light on the issue, with unique IDs for each individual product. 3D printer rocket fails The world's first 3D-printed rocket failed to make its planned Earth orbit schedule on its first test flight. It is the largest object ever produced in a 3D printer. Mitigating the effects of global warming with moon dust In a recent study, US scientists suggest using moon dust to combat global warming, since lunar dust shields a lot of sunlight with little mass. Other experts are critical of this method. Paper-thin solar cell turns any surface into a power source MIT engineers have developed ultra-light fabric solar cells that can quickly and easily turn any surface into a power source. With gold against steamed-up glasses Researchers at ETH Zurich have developed a coating for eyeglasses that heats up lenses with sunlight. The invention is intended to prevent them from fogging up. Wind energy in miniature Scientists in Singapore have developed a low-cost device that can harness the energy of light breezes and store it as electricity. Sensors and switches made of wood Sustainable electronic elements can be made from wood. This is helped by a novel process that uses a laser to engrave electrically conductive tracks into veneers. Black holes in wooden boards are supposed to dampen sound Black holes in the universe are so dense that not even light can escape. Empa researchers have now developed black holes for wooden boards that are not supposed to swallow everything, but at least sound. New water filter removes pathogens A research team from the Swiss Federal Institute of Technology Lausanne (EPFL) has presented a prototype of a low-cost filter that efficiently decontaminates water using only sunlight. The device is intended to provide clean drinking water for people in regions with little electricity.
