Before a solar storm races across space and impacts technology on Earth, it starts with an explosive process on the Sun known as magnetic reconnection. Now, observations from NASA’s Parker Solar Probe have uncovered new details about how these types of magnetic events fling particles to dangerous speeds. On aContinue Reading

The Bronx River is home to obsolete dams. Plans to remove them could boost efforts to restore dwindling river herring populations. By Lauren Dalban The Bronx River was once a curvy waterway that ran through vast forests and flowed into networks of tidal marshland. For centuries, river herring have swumContinue Reading
A rare fossil discovery is shedding light on the “missing years” of early sponge evolution. Scientists found a 550-million-year-old sponge that likely lacked hard skeletal parts, explaining why earlier fossils are so scarce. This supports the idea that the earliest sponges were soft-bodied and rarely preserved. The finding changes howContinue Reading
