Freshwater fish populations plunge 81% as river migrations collapse

​A massive global analysis found that nitrogen pollution can either speed up or dramatically slow the natural "breathing" of forest soils, depending on the ecosystem's condition. The results reveal hidden tipping points that could affect how forests store carbon and...

​Scientists have solved the mystery of the Seychelles’ vanished crocodiles using DNA from historic museum specimens. The reptiles were not a unique species after all, but an isolated population of saltwater crocodiles that likely drifted thousands of kilometers across...

​A casual walk through an Ithaca cemetery led to the discovery of a gigantic hidden bee population — roughly 5.5 million ground-nesting bees packed beneath the soil. Scientists believe it may be one of the largest bee aggregations ever documented and say the insects...

​Deep inside 100-million-year-old amber from Myanmar, scientists uncovered a bizarre ancient bug with clawed front legs that look more like a crab’s pincers than anything seen in modern insects. The discovery is so unusual that researchers say these crab-like “chelae”...

​Scientists found that storing mangoes at 54°F dramatically slows ripening and keeps the fruit fresh far longer than typical tropical temperatures. The cooler conditions helped mangoes stay firm, retain moisture, and preserve important antioxidants while reducing...

​Jupiter’s storms aren’t just gigantic — they may unleash lightning far more powerful than anything on Earth. Using NASA’s Juno spacecraft, scientists discovered that some lightning bolts on the gas giant could pack up to 100 times the punch of Earth’s lightning, and...

​For decades, scientists believed ancient humans avoided dense rainforests, treating them as nearly impossible environments for early survival. But a groundbreaking discovery in West Africa is rewriting that story. Researchers uncovered evidence that humans were...

​Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. By analyzing traces of DNA floating in seawater from depths exceeding...

​A remote island between Australia and Antarctica is showing signs of a dramatic climate transformation. Scientists found storms over Macquarie Island now unleash much heavier rainfall than they did decades ago, soaking ecosystems and altering fragile vegetation. The...
