How to force photons to never bounce back
Topological insulators are materials whose structure forces photons and electrons to move only along the material's boundary and only in one direction. These particles experience little resistance and travel freely past obstacles such as impurities,.....»»

Study reports that age is the driving force in changing how stars move within galaxies
Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the surrounding environment or the mass of the galaxy itse.....»»

First observation of photons-to-taus in proton–proton collisions
In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using.....»»
Mumpreneurs: A growing entrepreneurial force in Chinese society
While much ink has been poured over China's economic growth in recent decades, the contributions of Chinese women often receive less attention. With the pressure of the "three-child policy", being a mother isn't a mere personal choice, it's a part of.....»»
Using polarization to improve quantum imaging
Quantum imaging is a growing field that takes advantage of the counterintuitive and "spooky" ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon in the entangled duo gets.....»»
