News at a glance: AI weather forecasting, CRISPR relatives, and green hydrogen.

The article focuses on recent scientific and policy developments across multiple fields. It highlights a new artificial intelligence (AI) weather model, Pangu-Weather, developed by Huawei, which forecasts global weather with accuracy comparable to existing systems but over 10,000 times faster. In genetics, researchers affiliated with MIT discovered DNA-cleaving enzymes similar to those used in CRISPR in multicellular organisms, potentially advancing gene editing. Other topics include a major ancient rockslide shaping the Himalayas, improvements in green hydrogen production using silicon-perovskite solar cells, and a global survey challenging the traditional view that only men hunted in forager societies by showing women hunted in nearly 80% of groups studied.
