Researchers Realize Quantum Anomalous Hall Effect in Multilayered Insulator

New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect -- where an electrical current does not lose energy as it flows along the edges of the material -- over a broader range of conditions.

Researchers Discover Curious Starless Binary System of Brown Dwarfs

Star-forming processes sometimes create mysterious astronomical objects called brown dwarfs, which are smaller and colder than stars, and can have masses and temperatures down to those of exoplanets in the most extreme cases. Just like stars, brown dwarfs often wander alone through space, but can also be seen in binary systems, where two brown dwarfs orbit one another and travel together in the galaxy.

Massive Underground Instrument Finds Final Secret Of Our Sun's Fusion

A hyper-sensitive instrument, deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos (tiny particles pointing to the presence of carbon, nitrogen and oxygen) from our sun's core. These little-known particles reveal the last missing detail of the fusion cycle powering our sun and other stars.
