Recent studies have revealed that electrons passing through chiral molecules exhibit significant spin polarization--a phenomenon known as Chirality-Induced Spin Selectivity (CISS). This effect stems from a nontrivial coupling between electron motion and spin within chiral structures, yet quantifying it remains challenging.

To address this, researchers at the Institute for Molecular Science (IMS) /SOKENDAI investigated an organic superconductor with chiral symmetry. They focused on nonreciprocity related to spin-orbit coupling and observed an exceptionally a large nonreciprocal transport in the superconducting state, far exceeding theoretical predictions. Remarkably, this was found in an organic material with inherently weak spin-orbit coupling, suggesting that chirality significantly enhances charge current-spin coupling with inducing mixed spin-triplet Cooper pairs.

A new study reveals a strong connection between Arctic warming and the development of a rare thunderstorm that came closer to the North Pole than any previously recorded.

Scientists from UMass Amherst are among the researchers worldwide honored with the 2025 Breakthrough Prize in Fundamental Physics, awarded to the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC)  alongside its sister experiments ALICE, CMS and LHCb. Among the laureates are 36 scientists from the UMass Amherst research team, including 14 Ph.D. students, who produced results based on the data collected at the LHC from 2015 to 2018. The UMass Amherst team is led by physicists Stéphane Willocq, also the ATLAS spokesperson, as well as Benjamin Brau, Rafael Coelho Lopes de Sa, Carlo Dallapiccola and Verena Martinez Outschoorn.

Water molecules flip their orientation before splitting into hydrogen and oxygen. These acrobatics require significant energy, leading to the reaction’s inefficiency. Researchers quantified the precise energy costs of flipping. Efficiency is significantly affected by the water’s pH levels.

Researchers from Drexel University, the University of Pennsylvania, City University of New York and Monell Chemical Senses Center recently reported that American pallets are likely to accept pearl millet — a hardy, gluten-free grain that has been cultivated for centuries in rugged, drought conditions in Africa and India — as an acceptable substitute in recipes that use wheat flour.

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. UC Berkeley scientists found evidence for a complicated but apparently real process associated with fierce lightning storms: strong updrafts generate slushy, ice-coated hailstones of ammonia and water that eventually plunge into the planet and deplete areas of ammonia. This is part of the first 3D picture of the planet's atmosphere, which shows storms are primarily shallow.
