A long-standing mystery about the presence of hydrogen peroxide (H2O2) on Jupiter’s icy ocean moon Europa may be closer to being solved. Hydrogen peroxide forms as a byproduct when energetic particles break apart water molecules, leading to the recombination of OH radicals — highly reactive molecules with unpaired electrons. H2O2 was first observed on Europa by the Galileo Near Infrared …

An unusual fossil brain suggests that the ancestors of spiders and other arachnids may have once scuttled around the sea, rather than on land as was long thought, a new study finds. The fossil shows that certain features of the brain of a now-extinct animal known as Mollisonia symmetrica are arranged backward compared with those of most modern arthropods, a …

“This estimate shows that there is more plastic in the form of nanoparticles floating in the this part of the ocean, than there is in larger micro- or macroplastics floating in the Atlantic or even all the world’s oceans!,” said Helge Niemann, researcher at NIOZ and professor of geochemistry at Utrecht University. Mid-June, he received a grant of 3.5 million …

The special brains of spiders may have started to evolve in the oceans, long before their ancestors crawled onto land. A fresh look at a 500-million-year-old fossil by researchers from the University of Arizona and Lycoming College in the US and King’s College London has revealed remarkable similarities between the brains of extinct marine arthropods and modern-day arachnids. The discovery …

Since 2005, a 35-mile-long crack known as the East African Rift has been forming. In the scorching deserts of East Africa, the ground is slowly tearing itself apart — a slow-motion, geological drama. Over millions of years, the African continent will cleave in two, and scientists say a new ocean will one day fill the gap. The Afar region is …

Heidi Klum shared a video of herself swimming in the ocean on vacation. Soaking up the sun, she ditched her bikini top, wearing only her dark red bikini bottoms. She has been on vacation with husband Tom Kaulitz. Heidi Klum is in full vacation mode. In a new Instagram video, the model shared a clip of herself soaking up the …

OpenAI is releasing a new AI agent, creatively dubbed ChatGPT Agent — which is not to be confused with the two other AI agents it’s already released (did we mention that OpenAI has a bit of a branding problem?) In an announcement, the Sam-Altman-led company says the tool uses its own “virtual computer” to perform tasks on your behalf, like …

New clues from ancient seas are reshaping what we know about mass extinction and the future of our oceans. In a recent breakthrough, scientists have confirmed for the first time that a sudden, sharp drop in ocean pH—driven by a massive release of carbon dioxide—played a central role in wiping out entire ecosystems over 200 million years ago. A team …

The ground may feel steady underfoot, but the planet is always in motion. While satellites and sensors have mapped the surface in fine detail, what lies beneath remains largely unknown. The crust, a shell only 35 kilometers thick, is the farthest any probe has reached. To explore the deep interior—where the mantle and core reside—scientists must depend on indirect tools …
