After 17 years of research, a scientist has come up with one of the most important holy grails in physical chemistry

Absolute cross-sections scaled for each oxygen atom. The absolute cross-sections of each oxygen atom for a larger frequency band as derived from XAS measurements on fluidized proton complexes and on water in acetonitrile. attributed to him: Angewandte Chemie International Edition (2022). DOI: 10.1002 / ani.202211066 Professor Ehud Pines is considered an iconoclast. What else would … Read more

Full control of a six-qubit silicon quantum processor

The six-qubit processor described in this article. Qubits are created by adjusting the voltage on the red, blue, and green wires on the chip. The structures called SD1 and SD2 are very sensitive electric field sensors, which can even detect the charge of a single electron. These sensors, combined with advanced control systems, allowed the … Read more

Superconductivity model with 100,000 equations now contains only 4 thanks to AI: ScienceAlert

Electrons traveling through a mesh-like lattice do not behave like the pretty silver balls of a pinball machine. They blur and bend in group dances, following the whims of a wave-like reality that is hard to imagine, let alone compute. However, the scientists succeeded in doing just that, capturing the motion of electrons moving around … Read more

Scientists bring the fusion energy that lights up the sun and stars closer to reality on Earth

Physicist Min-Gu Yoo with slices of his paper in the background. Credit: Elle Starkman/PPPL Office of Communications; Collage by Kiran Sudarsanan Physicists at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have suggested the source of the sudden, baffling heat meltdown that precedes disruptions that could damage the donut-shaped tokamak fusion facilities. … Read more

Mysterious radiation explosions threaten cabin crew

On October 3, 2015, a National Science Foundation Gulfstream V research aircraft recorded a massive spike in atmospheric radiation as it flew over the South Atlantic Ocean between Antarctica and the tip of South America. For 11 minutes, the radiation detector on board watched the levels double, as if the plane had flown through a … Read more

No one in physics would dare say it, but the race to invent new particles is pointless | Sabine Huseinfelder

IImagine you are going to a zoology conference. The first speaker talks about her 3D model of a 12-foot purple spider that lives in the Arctic. There’s no evidence of their existence, she admits, but it’s a testable hypothesis, and she argues that a mission should be sent to search the Arctic for spiders. The … Read more

Einstein’s test of general relativity has big implications

The researchers used a satellite orbiting the Earth to do this Very accurate test It is a fundamental premise of Einstein’s general theory of relativity, which is the modern theory of gravitation. The question is whether two different types of mass – gravitational and inertial – are identical. Scientists found that two objects aboard the … Read more

Hurricanes orbiting Jupiter’s poles still baffle astronomers

Infrared image of Jupiter’s northern hemisphere as seen by Jerram. attributed to him: natural astronomy (2022). DOI: 10.1038 / s41550-022-01774-0 A team of multi-institutional space scientists in the United States, working with a colleague from Italy and one from France, used modeling to partly explain the resilience of hurricanes orbiting around Jupiter’s poles. In their … Read more
