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 ...

MIT scientists found that what we see is strongly influenced by how alert or active we are. Parts of the brain responsible for planning and control send specialized signals that either boost or quiet visual details. These areas seem to balance each . ...

Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified molecules that influence how long memories persist. ...

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 .. ...

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 .. ...

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 . ...

Scientists found that RSV infection early in life can set the stage for childhood asthma, particularly in kids already genetically prone to allergies. The virus appears to skew the developing immune system toward exaggerated responses to everyday ...

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, . ...

The discovery of strange, ultra-red objects--especially the extreme case known as The Cliff--has pushed astronomers to propose an entirely new type of cosmic structure: black hole stars. These exotic hybrids could explain rapid black hole growth in . ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing new data from NASA's Fermi Gamma-ray Space ...
