Researchers have been working for decades to understand the details of where the proton gets its intrinsic angular momentum, otherwise referred to as its spin. Recently, there have been indications that the spin contribution of the gluons could either be positive or negative. Now, a new approach that avoids assumptions and re-analyzes observational data with lattice quantum chromodynamics points strongly toward a positive gluon spin contribution, ∆g, to the proton spin.

A comprehensive seven-year study across 20 Chinese provinces has revealed a concerning rise in antimicrobial resistance (AMR) among diarrheagenic Escherichia coli (E. coli), a major foodborne pathogen.

Researchers explored Mendelian randomization to identify novel drug targets for metabolic dysfunction-associated steatotic liver disease (MASLD). This approach could revolutionize therapies for a condition affecting over one-third of adults globally.

Healing severe wounds requires strong, safe, and effective dressings to prevent infections. Researchers at the University of Lincoln and Shibaura Institute of Technology have developed a new type of wound patch by adding magnesium chloride to polyurethane nanofibers. These enhanced patches are stronger, more blood-compatible, and exhibit superior antibacterial properties than conventional ones, making them a game-changer for wound care. This innovative approach could improve healing outcomes and care for patients with serious injuries.

Professor Ma's team at Harbin Institute of Technology has recently achieved a breakthrough in the field of gas temperature detection. For the first time, they proposed a calibration-free temperature detection method based on light-induced thermoelastic spectroscopy (LITES) technology. This technique leverages the steady-state and transient response characteristics of a quartz tuning fork (QTF) to achieve rapid and highly stable temperature measurements in complex environments, providing a new solution for combustion diagnostics. The related results, titled "High stability and fast calibration-free temperature measurement based on light-induced thermoelastic spectroscopy," were recently published in Ultrafast Science.

Pomelo is a large citrus fruit commonly grown in Southeast and East Asia. It has a very thick peel, which is typically discarded, resulting in a considerable amount of food waste. In a new study, University of Illinois Urbana-Champaign researchers explore ways to utilize waste pomelo-peel biomass to develop tools that can power small electric devices and monitor biomechanical motions.

SAN ANTONIO — February 11, 2025 — Southwest Research Institute (SwRI) has developed new technology to enhance clinical bone imaging and decrease osteoporotic fractures in the elderly. The tool, described in a new SwRI-led study, uses artificial intelligence (AI) to create super-resolution images showing the inner structures of bones in great detail to better determine risk for fracture.

A new study has unveiled the genetic mechanism controlling citric acid content in jujube fruit, identifying a natural mutation in the promoter of the ZjACO3 gene.
