Astronomers studying the atmospheres of several intensely heated exoplanets uncovered an unexpected pattern that may reveal a hidden property of these distant worlds. Astronomers have uncovered the clearest evidence so far that some planets beyond our Solar System possess magnetic fields. By measuring atmospheric winds on seven extremely hot gas giants, researchers found signs that [...]

A new gravitational-wave catalogue reports 161 additional black hole mergers, bringing the total to 390 detections. Scientists at the University of Glasgow’s Institute for Gravitational Research are celebrating the release of a major new collection of gravitational wave discoveries, a milestone that highlights the rapid growth of gravitational astronomy. The latest Gravitational Wave Transient Catalogue [...]

A rare meteorite recovered from the Sahara Desert has revealed compelling evidence for a long-lost world that existed during the solar system’s earliest days. About 4.5 billion years ago, a large planetary body, potentially as large as the Moon or even Mars, orbited the Sun before colliding with another object and breaking apart. Now, researchers [...]

Tiny lab-grown brain models and the particles they release may reveal hidden differences among Alzheimer’s patients. Personalized treatment remains one of the biggest challenges in Alzheimer’s disease. Two patients can receive the same medication for symptoms such as depression, anxiety, or agitation and experience very different outcomes, leaving doctors with few ways to predict who [...]

A new study suggests that sleep loss during pregnancy and the postpartum period may be an early driver of anxiety symptoms. Lack of sleep is often treated as an unavoidable part of pregnancy and new parenthood. But what if those restless nights are doing more than leaving parents exhausted? New research suggests sleep loss may [...]

A study at one of Earth’s most isolated research stations offers new clues about how teams adapt during long periods of confinement. When people are isolated in extreme environments, it seems intuitive that spending more time together would strengthen social bonds. But new research suggests that under the right conditions, constant contact may actually create [...]

Ancient Australian fossils indicate that the earliest eukaryotes depended on oxygen, providing new evidence that oxygen helped enable the evolution of complex life. Stored in an open-air warehouse in tropical Darwin, Australia, are dozens of trays containing cylindrical cores of rock. They are from drill holes bored hundreds of meters below the surface by mineral [...]

Sentinel-6 satellite data shows strengthening warm-water waves in the Pacific, pointing to the likely arrival of El Niño and its global weather impacts later in 2026. Several months before an El Niño develops, large waves of warmer, elevated water travel eastward across the Pacific Ocean. Satellite observations in 2026 have detected several of these waves. [...]

Scientists have confirmed a rare “impossible” earthquake deep beneath Utah, revealing a hidden source of seismic activity inside Earth’s mantle. Nearly five decades after a puzzling earthquake struck deep beneath northern Utah, scientists have confirmed that the event was real and part of a rare category of earthquakes that occur much deeper underground than researchers [...]

A new study reveals that aging changes the body’s walking strategy, prioritizing balance and safety over efficiency. Walking may seem automatic, but every step requires a complex balance between stability, muscle coordination, and forward propulsion. As people age, that balance begins to shift. New research from Australia suggests the body gradually adopts a more cautious [...]

Researchers have identified a potential biological signature of sleep loss in saliva, bringing scientists closer to an objective test for detecting dangerous fatigue. A driver who has been awake for an entire day can be as impaired as someone who is legally intoxicated. Yet unlike alcohol, there is no roadside test that can objectively determine [...]

New ACC/AHA cholesterol guidelines promote earlier detection, personalized risk assessment, and more aggressive LDL cholesterol lowering to reduce long-term cardiovascular disease risk. For decades, cholesterol management has been a cornerstone of heart disease prevention. Yet despite widespread awareness, cardiovascular disease remains the leading cause of death worldwide, and millions of adults continue to have cholesterol [...]
