A hidden “switch-off” signal could predict solar storms seven years early
Scientists discovered a turning point in the Sun's 11-year cycle that could predict solar activity seven years earlier than current methods allow. At this "switch-off" point, violent space weather abruptly ends and remaining sunspots indicate the strength of the next cycle, with forecasts for Solar Cycle 26 expected in about two years.

Scientists calculated that Venus's clouds' unidentified dark ultraviolet material absorbs light far more strongly than previously thought. This finding narrows possibilities for determining whether the mysterious substance is organic, inorganic, or something unexpected.
Scientists find water was fueling volcanoes 3 billion years ago
Water-rich crustal material sank into Earth's mantle more than three billion years ago through a process called "dripduction," fueling volcanic eruptions. Ancient rocks from Western Australia provided evidence that this water-delivery mechanism operated long before modern plate tectonics fully developed.
Scientists discover a hidden switch that shuts down inflammation
Scientists discovered a natural braking system that switches off inflammation and prevents harmful immune cell buildup. Boosting this pathway in people reduced inflammation-related immune changes and accelerated pain relief.
