Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense laser light—researchers ...
Modern industry requires multi-dimensional performance design of protective structural materials. In nature, many organisms maintain the mechanical strength required for defense and achieve camouflage effects at the same ...
When galaxies collide, it's not a gentle affair, but it does take millions of years. Over this time, the two massive star systems slowly merge together, their gravitational pull drawing them closer. At the heart of each galaxy ...
Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South Atlantic—known as the ...
Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, which were first directly observed in 2015, are known to be produced during various cosmological phenomena, ...
The Nobel Prize in Physics was awarded to three scientists on Tuesday for discovering that a bizarre barrier-defying phenomenon in the quantum realm could be observed on an electrical circuit in our classical world.
Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These plasmonic waveguides could make ...
A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered a strange jet protruding ...
Plasma is a state of matter that emerges when a gas is heated to sufficiently high temperatures, prompting some electrons to become free from atoms. This state of matter has been the focus of many astrophysical studies, as ...
When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the momentum of light when it enters ...
