DOI: 10.1038/s41586-022-05008-1A team of researchers connected with several institutions in South Korea, working with two coworkers from Princeton University and one from Columbia University, has accomplished a new milestone in the development of...
When squeezed to high pressure between two diamonds (shown), a material made of carbon, sulfur and hydrogen can transmit electricity without resistance at room temperature.It is here: Researchers have reported the exploration of the first room-temperature superconductor after more than one century of waiting.The discovery evokes daydreams of futuristic technologies which could improve electronics...
Superexchange magnetic interactions in transition-metal oxides. Credit: Proceedings of the National Academy of Sciences (2022). DOI: 10.1073/pnas.2207449119Today, an international group of scientists led by Séamus Davis, Professor of Physics at the University of Oxford and University Cork, has announced outcomes that reveal the atomic mechanism behind high-temperature superconductors. The searchings for are released in PNAS.Superconductors are...

As it turns out, however, researchers at Microsoft, scientists at Brown University, and one professional who consulted for Disney's "Wrinkle in Time" believe the laws of physics may actually be slowly changing, complicating...
Experimental realization of a swimmer on a sphere with actuated motors on a freely rotating boom arm. Credit: Georgia TechWhen humans, animals, also machines move throughout the world, they always press against something, whether it is the ground, air, or water. Until currently, physicists thought this to be a constant, following the law of...
An artist’s conception of the complex magnetic correlations physicists have observed with a groundbreaking quantum simulator at Kyoto University that uses ytterbium atoms about 3 billion times colder than deep space. Different colors represent the six possible spin states of each atom. The simulator uses up to 300,000 atoms, allowing physicists to directly observe...
Scientists have developed a heat pump that uses light particles on a quantum range. Scientists can currently measure radio frequency signals closer to the quantum limit. Professionals say this technique works in searching for dark matter, a component of the universe whose existence is discernible primarily by its gravitational attraction. 30.1 percent of the...
Credit: CC0 Public DomainA new kind of "phase change" in water was first recommended 30 years ago in a research study by scientists from Boston University. Because the shift has been predicted to happen at supercooled problems, however, confirming its presence has been challenging. That is because, at these low temperatures, water really does...
A team of physicists from UNLV's Nevada Extreme Conditions Lab (NEXCL) used a diamond anvil cell, a research device similar to the one pictured, in their research to lower the pressure needed to observe a material capable of room-temperature superconductivity.

The L3 HAPLS at ELI Beamlines Research Center in the Czech Republic. Credit: ELI BeamlinesLawrence Livermore National Laboratory (LLNL) researchers have developed a compact multi-petawatt laser that uses plasma transmission gratings to overcome the power restrictions of traditional solid-state optical gratings. The design might allow the construction of an ultrafast laser up to 1,000...
