Weather-related power outages in the United States have become nearly twice as common in the last 10 years compared to the previous decade. These outages, which can last most of a day, are more than an inconvenience: lack of power and related indoor.....»»
New work reveals the "quantumness" of gravity
Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum mechanics......»»
Satellite images of plants" fluorescence can predict crop yields
Cornell researchers and collaborators have developed a new framework that allows scientists to predict crop yield without the need for enormous amounts of high-quality data—which is often scarce in developing countries, especially those facing heig.....»»
