A new University of California San Diego study uncovers a hidden driver of global crop vulnerability: the origin of rainfall itself.
Published in Nature Sustainability, the research traces atmospheric moisture back to its source—whether it evaporated from the ocean or from land surfaces such as soil, lakes and forests. When the sun heats these surfaces, water turns into vapor, rises into the atmosphere, and later falls again as rain.
An international team of scientists, led by the University of Oxford, has achieved a world-first by creating plasma "fireballs" using the Super Proton Synchrotron accelerator at CERN, Geneva, to study the stability of plasma jets emanating from blazars. The results, published today (3 November) in PNAS, could shed new light on a long-standing mystery about the Universe’s hidden magnetic fields and missing gamma rays.
Five-axis machining plays a pivotal role in manufacturing complex industrial components. In a recent study, researchers introduced a surface-partitioning and iso-scallop field-based strategy tailored for non-spherical cutting tools. By adaptively dividing machining surfaces and generating smooth tool orientations, the method significantly shortens tool paths, reduces machining time, and improves surface quality. This breakthrough not only enhances industrial productivity but also provides a foundation for integrating intelligent optimization in smart manufacturing.
