On a clear June day in Georgia, a blazing fireball suddenly fell out of the sky over the Atlanta metro area. The source of this spectacle was a 1-ton meteor that exploded in mid-air, sending a cherry tomato-sized fragment shooting through the roof of a McDonough home. Though no one knew it then, this space rock hailed from a time …

NASA’s Parker Solar Probe has delivered its closest and most detailed view yet of the Sun’s atmosphere, revealing the chaotic origins of the solar wind and space weather events that ripple across the solar system. The findings, based on a historic flyby in December 2024, reported by SciTechDaily, are reshaping scientists’ understanding of how the Sun’s activity can disrupt satellites, …

The human brain has to pull off a neat trick: keep yesterday’s memories safe while it writes today’s experiences into the same tissue – plasticity and stability at the same time. For decades researchers assumed that one set of molecular “sockets” handled every message at a synapse, whether that message was the everyday buzz of spontaneous activity or a carefully …

New water-resistant hydrogels, designed with the help of machine learning, are more adhesive than any comparable materials found in nature. The hydrogels were developed with the aid of an algorithm trained on the adhesives produced by natural organisms, such as geckos and mussels. The researchers that created them suggest that the new substances could have applications in areas such as …

National Weather Service staff at its Moon office got a few odd calls last night, about a strange-looking blue swirl moving across the sky. “We had a couple of calls on the overnight shift,” said NWS Meteorologist Andrew Kienzle. The swirl was created by a SpaceX rocket launch, experts said. The company’s Falcon 9 rocket launched on Tuesday from the …

Preprint servers such as PsyArxiv are contending with suspicious content written by AI systems.Credit: Nature The preprint’s title — ‘Self-Experimental Report: Emergence of Generative AI Interfaces in Dream States’ — roused psychologist Olivia Kirtley’s suspicions. When she clicked, her wariness grew. The manuscript, posted in July to PsyArXiv, a site for non-peer-reviewed research in the psychological sciences, was only a …

Did you see that gorgeous photo NASA astronaut Nichole Ayers took on July 3, 2025? Originally thought to be a sprite, Ayers confirmed catching an even rarer form of a Transient Luminous Events (TLEs) — a gigantic jet.    “Nichole Ayers caught a rare and spectacular form of a TLE from the International Space Station — a gigantic jet,” said Dr. …

For about 15 years, a powerful radio telescope on planet Earth dutifully recorded data about a location in the cosmos billions of light-years away from us — and, at last, astronomers managed to stitch together those extensive observations to reveal a full picture of what this telescope has been looking at. It’s … the Eye of Sauron! Well, sort of. …
