Near a black hole, gravity changes a quantum circuit’s readings, not its rules

by quasarn01 | Jul 26, 2026 | Latest in Physics

Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with extraordinary precision. Would intense...

Twisted laser light distinguishes mirror-image molecules by their fragment counts

by quasarn01 | Jul 26, 2026 | Latest in Physics

Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers (also called chiral molecules) is a...

Gamma-ray pulsations reveal extreme 3.2-millisecond pulsar 3,900 light-years away

by quasarn01 | Jul 26, 2026 | Astronomy

By analyzing the data from NASA’s Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray pulsations. The discovery was...

A quantum heat engine that simultaneously provides work and refrigeration

by quasarn01 | Jul 26, 2026 | Latest in Physics

The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous technologies, ranging from refrigerators...
