“This site reveals an extraordinary story of cultural continuity,” said Braun in a recent press release. When the going gets tough, the tough make tools Nomorotukunan’s layers of stone tools span the transition from the Pliocene to the Pleistocene, during which Earth’s climate turned gradually cooler and drier after a 2 to 3 million-year warm ..

Doubling cadence … This was the fourth flight of Europe’s new Ariane 6 rocket, and its third operational launch. Arianespace plans one more Ariane 62 launch to close out the year with a pair of Galileo navigation satellites. The company aims to double its Ariane 6 launch cadence in 2026, with between six and eight ..
Right now, we probably don’t have the ability to detect these small changes in phenomena. However, that may change, as a next-generation version of the Event Horizon Telescope is being considered, along with a space-based telescope that would operate on similar principles. So the team (four researchers based in Shanghai and CERN) decided to repeat ..
Even in its simplified form, however, it’s still a model of a quantum system, with all the computational complexity that comes with that. So the Quantinuum team modeled a few systems that classical computers struggle with. One was simply looking at a larger grid of atoms than most classical simulations have done; another expanded the ..
It was probably always when, not if, Google would add its name to the list of companies intrigued by the potential of orbiting data centers. Google announced Tuesday a new initiative, named Project Suncatcher, to examine the feasibility of bringing artificial intelligence to space. The idea is to deploy swarms of satellites in low-Earth orbit, ..
Many insect species hear using tympanal organs, membranes roughly resembling our eardrums but located on their legs. Grasshoppers, mantises, and moths all have them, and for decades, we thought that female stinkbugs of the Dinidoridae family have them, too, although located a bit unusually on their hind rather than front legs. Suspecting that they use ..

You’ll often hear plastic pollution referred to as a problem. But the reality is that it’s multiple problems. Depending on the properties we need, we form plastics out of different polymers, each of which is held together by a distinct type of chemical bond. So the method we use to break down one type of ..
“Other authors point out that symbolic and utilitarian functions are intimately linked among traditional populations,” wrote D’Errico and his colleagues, “and that, as a result, it would have been difficult for a systematic use of ocher powders to exist over a long period of time without a symbolic dimension being rather quickly attached to it.” ..
For four decades, a frequently acrimonious debate has raged in paleontological circles about the correct taxonomy for a handful of rare fossil specimens. One faction insisted the fossils were juvenile Tyrannosaurus rex; the other argued that they represented a new species dubbed Nanotyrannus lancensis. Now, paleontologists believe they have settled the debate once and for ..
