Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.
Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. ...
When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated ...
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev's astounding productivity in pumping out academic ...
Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists ...
Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first ...
More accurate navigation systems and improved wireless communications may not come from traditional electronics, but rather from atoms. Researchers at Penn State and the National Institute of Standards and Technology (NIST) ...
A new study from scientists at Purdue University reports that far-red radiation, in combination with increased carbon dioxide (CO₂) concentration, significantly enhances biomass production in young leaf lettuce grown under ...
Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in ...
