A rare fossil discovery is shedding light on the "missing years" of early sponge evolution. Scientists found a 550-million-year-old sponge that likely lacked hard skeletal parts, explaining why earlier fossils are so scarce. This supports the idea .. ...

In the Arizona desert, scientists have uncovered a bizarre and almost unbelievable partnership between ants: tiny cone ants acting as "cleaners" for much larger harvester ants. Instead of attacking, the smaller ants crawl over the giants, licking and ...

In the aftermath of Earth's most catastrophic extinction event, one unlikely survivor rose to dominate a shattered world: Lystrosaurus. Now, a stunning fossil discovery--an ancient egg containing a curled-up embryo--has finally answered a decades-old ...

A breakthrough experiment has shed new light on one of astrophysics' biggest mysteries: the origin of rare proton-rich elements. For the first time, scientists directly measured a key reaction that creates selenium-74 using a rare isotope beam. The . ...

A new study from the University of Hawaii at Mnoa is overturning a decades-old belief that Indigenous Hawaiians hunted native waterbirds to extinction. Instead, researchers found no scientific evidence supporting this claim and propose a more complex ...

Bread and other carbohydrate staples may be doing more than just filling plates--they could be quietly reshaping metabolism. In a surprising twist, researchers found that mice strongly preferred carbs like bread, rice, and wheat, abandoning their ...

Quantum systems can secretly "remember" their past--even when they appear not to. Scientists found that whether a system shows memory depends on how you look at it: through its evolving state or its measurable properties. Each perspective uncovers .. ...

For years, water managers have been puzzled as the Colorado River kept delivering less water than expected--even when snowpack levels looked promising. New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier ...

Mitochondria don't just generate energy--they also carefully organize their own DNA in a surprisingly elegant way. Scientists have discovered that a long-overlooked phenomenon called "mitochondrial pearling," where mitochondria briefly form bead-like ...

Spending time with close companions might do more than strengthen bonds--it could also reshape your gut bacteria. In a study of island birds, those with stronger social ties shared more gut microbes, especially types that require direct contact to .. ...
