When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used light to visualize tiny magnetic regions, known as magnetic domains, in a specialized quantum material. Their study was published […]

Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle’s observations two millennia ago and modern-day understanding, while opening the door to a whole host of “cool”—and “cooling”—implications.

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable than others. These nuclei had specific numbers of protons or neutrons, or magic numbers, as physicist Eugene Wigner called them.

In fusion experiments, understanding the behavior of the plasma, especially the ion temperature and rotation velocity, is essential. These two parameters play a critical role in the stability and performance of the plasma, making them vital for advancing fusion technology. However, quickly and accurately measuring these values has been a major technical challenge in operating […]

The Nobel Prize in physics is being awarded Tuesday, a day after two American scientists won the medicine prize for their discovery of microRNA.

Two pioneers of artificial intelligence—John Hopfield and Geoffrey Hinton—won the Nobel Prize in physics Tuesday for helping create the building blocks of machine learning that is revolutionizing the way we work and live but also creates new threats to humanity, one of the winners said.

Observations of preschool children in classrooms and playgrounds have uncovered new social phases in human movement. Employing ultra-wideband radio frequency identification (UWB-RFID) technology allows for the precise tracking of children’s movements, revealing a “gas-like” phase of free, independent movement and a “liquid-vapor coexistence” phase where small groups dynamically form and disperse.
