Physicists discover a way to imprint a previously unseen geometrical form of chirality onto electrons
Have you ever placed the palm of your left hand on the back of your right hand in such a way that all fingers point in the same direction? If you have, then you probably know that your left thumb will not touch its right counterpart. Neither rotation.....»»
Observation of 3D acoustic quantum Hall states
The quantum Hall effect (QHE) is one of the most notable discoveries in condensed matter physics, opening the door to topological physics. Extending QHE into three dimensions is an inspiring but challenging endeavor. This difficulty arises because th.....»»
Researchers demonstrate anomalous Brewster effect in metamaterials
The Brewster reflectionless effect stands out as one of the simplest yet pivotal discoveries in manipulating waves. Initial investigations were limited to isotropic materials, but later, thanks to the advent of metamaterials, the phenomenon was found.....»»
Researchers demonstrate how to build "time-traveling" quantum sensors
The idea of time travel has dazzled sci-fi enthusiasts for years. Science tells us that traveling to the future is technically feasible, at least if you're willing to go near the speed of light, but going back in time is a no-go. But what if scientis.....»»
The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities
In the summer of 2022, a research cruise detected a massive harmful algal bloom (HAB) in the Bering Strait region of western Alaska. This expedition provided a dramatic example of science utilizing new technology to track a neurotoxic HAB, and effect.....»»
