Researchers at Florida Atlantic University’s Harbor Branch Oceanographic Institute have released a landmark review tracing four decades of changes in pelagic sargassum – free-floating brown seaweed that plays a vital role in the Atlantic Ocean ecosystem. Once thought to be primarily confined to the nutrient-poor waters of the Sargasso Sea, sargassum is now recognized as…
Under high-emission scenarios, the Atlantic Meridional Overturning Circulation (AMOC), a key system of ocean currents that also includes the Gulf Stream, could shut down after the year 2100. This is the conclusion of a new study, with contributions by the Potsdam Institute for Climate Impact Research (PIK). The shutdown would cut the ocean’s northward heat…

The mission was part of NASA’s Mercury human spaceflight programme and came just nine months after Soviet cosmonaut Yuri Gagarin became the first person in space. Another significant moment came when Glenn used a camera he had purchased from a…
Solar storms pose a threat to electronic systems on Earth Solar Dynamics Observatory, NASA. We may one day be able to forecast powerful solar storms capable of devastating Earth’s electronics more than half a day in advance, following a successful test of the approach using the Solar Orbiter spacecraft. The sun occasionally releases powerful blasts…
