For decades, archaeologists have been uncovering rare and mysterious incised obsidian arrowheads across Neolithic Central Anatolia, each one bearing a unique design etched into its glassy black surface nearly 9,000 years ...
The most prominent difference between human male and female skeletons is the pelvis, which anthropologists often use to determine the sex of ancient remains. Scientists have long believed the human pelvis evolved mainly as ...
For close to a century, physicists have pursued a way to unite gravity with quantum mechanics. Known as quantum gravity, this goal has remained frustratingly out of reach so far. Similarly elusive is the force of dark energy, ...
Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia ...
Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a ...
As they build their nests, many birds are known to interweave dried grasses and other materials with green plants, such as fresh leaves, grass stems, herbs and aromatic leaves. While this behavior is well documented, why ...
Astronomers have detected an enormous cloud of gas tens of millions of degrees hot surrounding one of the most extreme structures known in the early universe. The study offers one of the clearest views yet of a galaxy cluster ...
Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries ...
We reach for brighter, better lighting for sharper pictures, whether we're photographing a puppy or a microscopic cell. In most cases, the light comes from outside the object being photographed. A recent study explored a ...
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
