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 ...
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 ...

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 ...
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 ...
As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.
In nature, the rarest ingredient can be the one that holds everything together. In a new article published in Trends in Ecology & Evolution, Dr. Erika C. Freeman of the Leibniz Institute of Freshwater Ecology and Inland Fisheries ...
