New research shows living near oil and gas development in California is a risk factor for preterm birth, the leading cause of infant death in the United States. About 2.1 million Californians live within one mile of an active oil or gas well.
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars, robots or even drones. The technology could be scaled up to power electric cars as they drive over highways, robots on factory floors and drones hovering over rooftops.
