Experimental determination of the proton’s gluonic gravitational form factors may have revealed part of proton’s hidden mass — ScienceDaily
Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has revealed the radius of the proton’s mass that is generated by the strong force as it glues together the proton’s building…

Improving future electronic devices through oxide materials
This figure shows that when the electrons are controlled using the Rashba effect (which involves a perpendicular internal field, E0), there are changes in the way they move and interact with each other in a material. This change causes the material structure to distort, similar to when you push and pull on a rubber band.…

Physics – Spinning Heat in Reverse
March 30, 2023• Physics 16, s43 When spun fast enough, a cold object can transfer heat to a nearby hot object. J. R. Deop-Ruano and A. Manjavacas [1] J. R. Deop-Ruano and A. Manjavacas [1] × Heat flows from hot to cold, but a fast spin could break that rule. Juan Deop-Ruano and Alejandro Manjavacas…

Racial Inequity in Key Publication Metrics
March 30, 2023• Physics 16, 53 Non-white scientists—in particular Black scientists—are underrepresented on editorial boards, receive proportionally fewer citations, and experience longer review times for their papers, factors that can all impact their career prospects. BortN66/stock.adobe.com Journal editorial boards exhibit inequities in their staff, with non-white scientists underrepresented on editorial boards. In addition, the papers…

Old data show new evidence for Venusian volcanism
NASA deployed the Magellan spacecraft in 1989 to map the surface of Venus. Credit: NASA There are volcanoes on Venus, more than any other planet in the solar system. A lot of what’s known about the planet’s volcanism comes from NASA’s Magellan spacecraft, which orbited Venus and collected surface images with synthetic aperture radar from…

This Surprisingly Simple Shape Solves a Longstanding Mathematical Problem : ScienceAlert
A group of mathematicians has unveiled a brand new 13-sided shape they’ve simply called ‘the hat’. Don’t let the rather mundane description fool you though. This hat (which looks a bit like a fedora) is next season’s must-have fashion item, able to be tiled across a plane to create patterns that never repeat. Shapes like…

A Look at The Proton’s Inner Structure Shows How Its Mass Isn’t The Same as Its Size : ScienceAlert
The humble proton is a lynchpin of the material Universe. Its characteristics define chemistry, governing teams of electrons that build atoms into molecules, and molecules into dazzling complexity. For all we understand of its behavior, the proton’s internal structure is a chaotic mess of activity scientists are still deciphering. A new experiment conducted at the…
