Scientists and environmental activists have consistently called for drastic reductions in meat production as a way to reduce emissions and, in doing so, combat climate change. However, a new analysis concludes that a smaller reduction, […]
Between about 120 million and 130 million years ago, during the age of dinosaurs, temperate forests and lakes hosted a lively ecosystem in what is now northeast China. Diverse fossils from that time remained pretty […]
The unique properties of baseball’s famed “magic” mud have never been scientifically quantified—until now. In a paper in Proceedings of the National Academy of Sciences, researchers at the University of Pennsylvania School of Engineering and […]
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to […]

Two-thirds of the world’s food comes today from just nine plants: sugar cane, maize (corn), rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet and cassava. In the past, farmers grew tens of thousands of crop […]
Radio frequency (RF) and microwave power measurements are widely used to support applications across space, defense, and communication. These precise measurements enable engineers to accurately characterize waveforms, components, circuits, and systems.This post was originally published […]
If we want to use hydrogen as fuel for cars or airplanes, or for chemical storage of excess renewable energy, it would be most efficient if it were liquid. However, this would require cooling it […]
Political violence is hardly new to America. Since the country’s inception, gunmen have shaped its political landscape, from the Civil War to the Ku Klux Klan, to high-profile assassinations and the bombing of federal buildings. […]
