“Nanotechnology engineers from Princeton have 3-D printed an ear from calf cells and silver nanoparticles that picks up radio signals at frequencies beyond human capacity. The creation is part of their greater plan to one day build spare parts for human cyborgs.”
“When people think of air pollution, they usually picture a factory spewing a plume of toxic chemicals into the air. But indoor air pollution causes significant health effects such as respiratory illness, asthma attacks, cancer and premature death…Fine particulates are found indoors mainly due to cooking, burning candles or incense, tobacco smoke, and outdoor sources that leak inside.
