Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions ...
In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"—my ...
The origin of spin in spiral and elliptical galaxies has posed a long-standing puzzle for astronomers. One idea, known as tidal torque theory, proposes that galaxies' spins are an imprinted record of the early universe, imparted ...
On Mother's Day weekend in May 2024, Earth experienced its most powerful geomagnetic storm in two decades, spawning auroras—the ribbony bands of light in the nighttime skies in the Northern and Southern hemispheres—that may ...
Scientists have made a surprising finding about how an asexually reproducing stick insect has evolved. Research led by Dr. Darren Parker, lecturer in evolutionary biology at Bangor University, studied the genes of several ...
An international team of researchers has uncovered a previously undetected structure in the birdsong of Bengalese finches that has the same statistical patterns found in human languages.
A tall glass of ice water isn't just a thirst quencher; it's also an everyday example of coexisting phases. Water can exist simultaneously in both liquid and solid phases. As it turns out, this phase duality can also exist ...
Using a detector filled with nearly 9 metric tons of liquid xenon, researchers have delivered some of the most sensitive dark matter results ever recorded. In the latest analysis from the XENON collaboration, working at the ...
Dark matter's existence is all but certain—astronomers believe it makes up about a quarter of the universe's total energy content—yet its true identity has eluded us for decades. Two of the leading candidates for dark matter ...
Neanderthals were generally more strongly built than most people living today. Their bones show signs of large muscles, and they had characteristic features such as prominent brow ridges and relatively short tooth roots.
