Even though the solar wind was unusually dense during the May 2024 superstorm, ions from the solar wind contributed very little to the ring current, marking the first time both were observed simultaneously during a storm of this magnitude. In May 2024, auroras spread into skies far beyond their usual range, appearing at unusually low […]
Scientists Expose Unexpected Driver of the May 2024 Superstorm
Even though the solar wind was unusually dense during the May 2024 superstorm, ions from the solar wind contributed very little to the ring current, marking the first time both were observed simultaneously during a storm of this magnitude. In May 2024, auroras spread into skies far beyond their usual range, appearing at unusually low […]
Scientists Find a New Way To Hear the Faint “Ringing” of Black Holes
A new method maps the subtle gravitational wave vibrations produced by merging black holes, potentially enabling more precise tests of general relativity. When two black holes collide, the violence of the merger does not end immediately. The newly formed, larger black hole continues to ‘ring’ as it settles into a stable shape, and researchers have […]
JWST Captures Stunning Evidence of How Supermassive Black Holes Feed
An international team using the JWST has found photographic evidence that brings astronomers closer to solving a long-standing mystery about black holes. For decades, astronomers have faced a puzzle at the centers of massive galaxies: how can a supermassive black hole keep feeding when its own powerful jets heat the surrounding gas that supplies it? […]
Early Exercise May Permanently Change How Much Energy the Body Uses To Move
An active childhood may train the growing body to make movement less demanding for life. A Penn State-led experiment found that birds raised while carrying extra weight became remarkably economical walkers. Once mature, they could transport the added load without using more energy than ordinary birds needed to walk unburdened. The findings offer rare direct […]

Aging Changes Memory in a Surprising Way, New Study Finds
A new study finds that as people age, they remember fewer details from their past and have more difficulty switching between different types of memories. As people grow older, the broad story of a past experience may remain even as the sights, sounds, and emotions tied to a particular moment become harder to retrieve. Research […]
Scientists Can Now See DNA Folding at Near-Molecular Resolution
The finding could eventually enable the use of DNA packaging in cells for disease diagnosis and treatment. In preserved cells, newly developed fluorescent probes allowed researchers to pinpoint individual dye molecules to within 3 nanometers, close to the width of the DNA double helix itself. The same molecules can also reveal how DNA is packaged […]
