4,900 years ago, a Neolithic people on the Danish island Bornholm sacrificed hundreds of stones engraved with sun and field motifs. Archaeologists and climate scientists can now show that these ritual sacrifices coincided with a large volcanic ...
A new study has revealed the alarming extent glaciers have shrunk over the past 40 years in a global warming hotspot -- and the biggest retreat has occurred in recent years.
Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact crater 66 million years ago. A new study questions . ...
In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At that time, it began emitting radio waves at 60 times . ...
When a bird drapes its nest with snake skin, it isn't just making an interesting decor choice. Researchers find that for some birds, it keeps predators at bay.

A long-standing question about when archaic members of the genus Homo adapted to harsh environments such as deserts and rainforests has been answered in a new research paper.
A research team has discovered another piece in the puzzle of the formation of the Moon and water on Earth. The prevailing theory was that the Moon was the result of a collision between the early Earth and the protoplanet Theia. New measurements ...
A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny specks of a quark-gluon plasma (QGP). Scientists ...
New insect-scale microrobots can fly more than 100 times longer than previous versions. The new bots, also significantly faster and more agile, could someday be used to pollinate fruits and vegetables.
