May 1, 2024 The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study. The researchers combined 2019 satellite observations with an atmospheric transport model to generate a high-resolution map of methane emissions, which was then compared to EPA estimates from the same year. The researchers found: Methane emissions ...

Apr. 29, 2024 How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place for up to 30 months to laterally buttress the emerging permanent sabers. By the time the baby teeth ...
