Supply Chain Software
By 2020, NASA plans to establish a long-term human presence on the Moon. To make this possible, a reliable stream of consumables such as fuel, food and oxygen, spare parts, and exploration equipment would have to make its way from the Earth to the Moon as predictably as any Earth-based delivery system. To figure out how to do...

PCB Bacteria
Researchers at Rensselaer Polytechnic Institute have discovered a tiny anaerobic bacterium that could one day transform how polychlorinated biphenyls (PCBs) are removed from the environment. The organism could be the key to developing methods that help detoxify commercial PCB compounds on site -- without the need for dredging.
