The motion of a tiny number of charged particles may solve a longstanding mystery about thin gas disks rotating around young stars, according to a new study from Caltech.
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are compatible ...
In a new publication from Opto-Electronic Advances, researchers from the National University of Singapore, Singapore, discuss confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature.
Gazing at the night sky can evoke a sense of wonder regarding humanity's place in the universe. But that's not all it can evoke. If you're knowledgeable about asteroid strikes like the one that wiped out the dinosaurs, then ...
An astronaut steps into a body scanner and, hours later, walks on Mars in a custom-made spacesuit, breathing oxygen that was extracted from Mars' carbon dioxide-rich atmosphere. On Venus, an inflatable bird-like drone swoops ...
Even the finest particles of pollution influence the process of cloud formation and the rainfall regime. A study conducted in Manaus, the capital of Amazonas state in Brazil's North region, shows that oxidation leads small ...
Animal cells can use elements or ions to generate electrical impulses. These impulses are then conveyed from one cell to another, traveling across cellular networks.
Imagine a ball thrown in the air: it curves up, then down, tracing an arc to a point on the ground some distance away. The path of the ball can be described with a simple mathematical equation, and if you know the equation, ...
In 2021 so far, some 2467 new objects large enough to be tracked have been added to world catalogs of orbital objects, out of which 1493 are new satellites and the rest are debris. While new objects are added, others are ...
In the race toward practical fusion energy, tokamaks (donut-shaped plasma devices) are the leading concept—they have achieved better confinement and higher plasma temperatures than any other configuration. Two major magnetic ...
