For more than a century, astronomers have puzzled over a strange discrepancy in the historical record. Theta Eridani, a modest star in the constellation Eridanus, is the third-brightest star in its constellation, with a magnitude of 2.9. But ancient astronomers described it very differently. A new study, posted to the arXiv preprint server on June 29, has proposed a plausible explanation for this mystery.

Quantum computers, devices that process information by leveraging the laws of quantum mechanics, have been found to outperform classical computers in some advanced tasks. Instead of storing information in the form of classical binary bits (i.e., 0 or 1), quantum computers rely on quantum bits (i.e., qubits), which can also exist in combinations of 0 and 1 states.

A new paper in the journal Nature Physics offers insights into the physics of liquid droplets—and while many people may not appreciate the mathematical accomplishment, they will benefit from the athletic wear and raincoats it makes possible. The recent article, “Tricky Tension,” explores the intersection of physics and textiles and how wetting is influenced by the structure of tiny individual liquid droplets.
