Study uncovers how calcium controls insulin quality in the endoplasmic reticulum‎

Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum (ER), a cellular organelle that synthesizes and transports proteins, has not been elucidated. This control system of protein quality, known as proteostasis, was put under a microscope by researchers to find a more thorough understanding of the process, potentially revealing clues about how to prevent Type 2 diabetes, Alzheimer's and amyotrophic lateral sclerosis (ALS).

New method uses spin motion to control heat flow in magnetic materials‎

NIMS, in joint research with the University of Tokyo, AIST, the University of Osaka, and Tohoku University, have proposed a novel method for actively controlling heat flow in solids by utilizing the transport of magnons—quasiparticles corresponding to the collective motion of spins in a magnetic material—and demonstrated that magnons contribute to heat conduction in a ferromagnetic metal and its junction more significantly than previously believed.

Veritas explores the nature of a mysterious gamma-ray emitter‎

Astronomers have employed the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to observe a mysterious gamma-ray emitting source designated HESS J1857+026. Results of the observational campaign, published December 19 on the pre-print server arXiv, shed more light on the nature of this source.

Spin-engineered copper nanozyme enables efficient lignin conversion and strong green adhesives‎

Lignin is the most abundant renewable aromatic polymer in nature. Its conversion into high value-added chemicals or materials is essential for biomass valorization and sustainable development. Nanozymes, which combine the catalytic efficiency of natural enzymes with the stability of nanomaterials, offer a highly promising green approach for lignin degradation.
