At the heart of our galaxy lies a cosmic puzzle: although the Galactic Center is packed with star-making material, massive stars form there surprisingly slowly. Using NASA's retired SOFIA observatory, scientists captured rare high-resolution infrared views that revealed dozens of new stars being born, but not in the numbers or sizes one might expect....

Aphid-hunting wasps can reproduce with or without sex, challenging previous assumptions. This unique flexibility could boost sustainable pest control if its hidden drawbacks can be managed....

Underground fungi may be one of Earth s most powerful and overlooked allies in the fight against climate change, yet most of them remain unknown to science. Known only by DNA, these "dark taxa" make up a shocking 83% of ectomycorrhizal species fungi that help forests store carbon and thrive. Their hotspots lie in tropical forests and other underfunded regions. Without names, they re invisible to conservation efforts. But scientists are urging more DNA sequencing and global collaboration to bring these critical organisms into the light before their habitats, or the fungi themselves, disappear forever....

A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere....

Atmospheric rivers, while vital for replenishing water on the U.S. West Coast, are also the leading cause of floods though storm size alone doesn t dictate their danger. A groundbreaking study analyzing over 43,000 storms across four decades found that pre-existing soil moisture is a critical factor, with flood peaks multiplying when the ground is already saturated....

A University of Queensland-led project has developed a tool to standardise genetic testing of koala populations, providing a significant boost to conservation and recovery efforts....

AI has helped astronomers crack open some of the universe s best-kept secrets by analyzing massive datasets about black holes. Using over 12 million simulations powered by high-throughput computing, scientists discovered that the Milky Way's central black hole is spinning at nearly maximum speed. Not only did this redefine theories about black hole behavior, but it also showed that the emission is driven by hot electrons in the disk, not jets, challenging long-standing models....

Ten thousand years after mastodons disappeared, scientists have unearthed powerful fossil evidence proving these elephant cousins were vital seed spreaders for large-fruited trees in South America. Using dental wear, isotope analysis, and fossilized plant residue, researchers confirmed that mastodons regularly consumed fruit supporting a decades-old theory that many tropical plants evolved alongside giant animals. The extinction of these megafauna left a permanent ecological void, with some plants now teetering on the edge of extinction. Their story isn t just prehistoric it s a warning for today s conservation efforts....

UC San Diego engineers have created a passive evaporative cooling membrane that could dramatically slash energy use in data centers. As demand for AI and cloud computing soars, traditional cooling systems struggle to keep up efficiently. This innovative fiber membrane uses capillary action to evaporate liquid and draw heat away without fans or pumps. It performs with record-breaking heat flux and is stable under high-stress operation....
