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 …

Jason Breen is no stranger to wildlife encounters. As an avid surfer and water sportsman, he’s seen lots of marine animals around his home in Sydney, Australia. In fact, a few years ago, a humpback whale rocketed out of the water right in front of his board. When Breen recently heard about a huge animal trapped in a tidal pool, …

Scientists analyzing sediment scraped from a rugged ridge nearly three miles under the Central Pacific Ocean expected calm, predictable chemistry. Instead they found a dense band of the radioactive isotope beryllium‑10 (10Be) packed into the layer that formed about 10 million years ago. This enough extra atoms to raise the normal background by roughly seventy‑three percent. Dr. Dominik …

Some intriguing new measurements of salinity in the oceans around Antarctica have set off reams of sensationalist speculations. Maybe some context is helpful… What we’ve been seeing The climate change situation in the Southern Oceans (those seas surrounding Antarctica and connected by the massive Antarctic Circumpolar current) have been anomalous for many years, decades even. While even the earliest climate …

In a world where towering waterfalls like Niagara Falls and Angel Falls capture our imagination, there is one waterfall so vast, yet hidden, that it dwarfs all others. Found beneath the cold waters of the Arctic, the Denmark Strait cataract, Earth’s largest waterfall, is a natural wonder that no human eye has ever seen in its full, mighty descent. Stretching …
