1. New 3D scan reveals a hidden network of moai carvers on Easter Island

   A high-resolution 3D model of Rano Raraku shows that the moai were created in many distinct carving zones. Instead of a top-down system, the statues appear to have been produced by separate family groups working independently while sharing techniques. Evidence of varied carving styles and multiple transport routes supports this decentralized picture. The results challenge old assumptions about how large-scale monument building worked on Rapa Nui.

2. Scientists discover hidden wolf DNA in most dogs

   Researchers studying thousands of canine genomes discovered that wolf DNA is still present in most dog breeds. This ancient genetic influence shows up in traits like body size, behavior, and environmental resilience. Even dogs bred far from wolves, including tiny chihuahuas, carry detectable wolf ancestry. The findings highlight how deeply intertwined the histories of dogs and wolves really are.

3. Scientists find coastal seas acidifying shockingly fast

   New findings show that some coastal regions will become far more acidic than scientists once thought, with upwelling systems pulling deep, CO2-rich waters to the surface and greatly intensifying acidification. Historic coral chemistry and advanced modeling reveal that these regions are acidifying much faster than expected from atmospheric CO2 alone, raising serious concerns for fisheries, marine ecosystems, and coastal economies.

4. 242-million-year-old mini predator changes lizard evolution

   A tiny 242-million-year-old fossil from Devon is shaking up scientists’ assumptions about the earliest members of the lizard lineage. Instead of the expected skull hinges and palate teeth typical of modern lizards and snakes, this ancient creature shows a surprising mix of primitive and unusual traits—along with strikingly large, blade-like teeth. High-resolution synchrotron scans revealed details invisible to the naked eye, helping researchers name the new species Agriodontosaurus helsbypetrae and rethink the origins of lepidosaurs, the diverse group that now includes more than 12,000 species.

5. Dinosaur mummy found with hooves and a hidden crest

   Scientists have reconstructed the most complete and lifelike profile of Edmontosaurus annectens thanks to an extraordinary preservation process called clay templating, in which a thin clay film captured the dinosaur’s skin, scales, spikes, and even hooves in three dimensions. By combining newly excavated “mummies,” advanced imaging, and artistic reconstruction, researchers revealed a tall crest, a single row of tail spikes, delicate pebble-like scales, and—most remarkably—the earliest known hooves in any land vertebrate.
