Hurricane Melissa devastated Jamaica as a stunning Category 5 storm. But the U.S. was spared as the Federal Emergency Management Agency faces drastic change. By Amy Green The 2025 Atlantic hurricane season may be best-remembered for its unusual distribution of storms, including Melissa, which struck Jamaica as a devastating CategoryContinue Reading
Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light via a vertebrate-like c-opsin. The discovery reveals deep evolutionary parallels between distant species and raises questions about how light shapesContinue Reading
Southeast Asia has been hit by unusually severe floods this year, with late storms killing more than 1,400 people and leaving hundreds missing across Indonesia, Sri Lanka, and Thailand. Scientists say the devastation reflects a warming global climate turbo-ch…Continue Reading
