Distinguishing between brown dwarfs and giant planets has confused astronomers, but a clear separating factor has finally been identified.

Researchers at the University of Science and Technology of China have demonstrated that quantum entanglement between pairs of atomic defects in diamond can sharpen nanoscale sensors well beyond ...

Melting ice sheets and rising seas are redistributing enough mass across the planet to measurably slow Earth’s rotation, stretching the length of each day at a rate not seen in 3.6 million years. A ...

For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

Physicists show that magnetoelastic coupling, present in nearly all magnets, can generate skyrmion arrays without crystal ...

Skyrmions, in which electron spins inside a magnet are arranged like vortices, are a key structure in next-generation spintronics technology. KAIST researchers have shown that skyrmions can form using ...

A magnetic crystal that was thought to behave like a quantum system, CeMgAl11O19, revealed something even stranger: a new ...

Spin separates giant planets from 'failed stars' Clearest evidence yet that giant planets spin faster than their cosmic lookalikes. (Nanowerk News) Astronomers have ...

David Carlson of Franklin is a professor emeritus of philosophy and religion. Columns such as this, published on a printed ...

Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only under specific conditions that researchers have struggled for decades to ...

The new study described this "almost unprecedented rate of increase" in the length of an average day as a quantifiable ...

Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge ...
