Salam Daher, an associate professor of informatics at NJIT, used scans and digital models of skin abnormalities to develop a system that analyzes and monitors damaged skin regions.

Syphilis is curable, but it’s hard to catch and dangerous if undetected. A new rapid syphilis test from a team led by Penn State researchers detects lower levels of the body’s antibodies against it, potentially leading to better diagnostic care and fewer congenital cases.

Depending on the cultivar, higher concentrations of carbon dioxide (CO₂) in the atmosphere can significantly alter the protein composition of wheat. This affects not only baking quality but potentially also the tolerability of wheat products. This is the conclusion of a new study led by the Leibniz Institute for Food Systems Biology at the Technical University of Munich. According to the study, the adaptation of crops to climate change should in the future focus not only on high yields but also on quality characteristics such as protein composition.

High-entropy carbides are promising noble-metal-free catalysts for hydrogen evolution, yet the nanocrystals reported so far have all been dense solids, and their metallic constituents have been drawn mainly from groups IVB–VIB metals. Recently, a team of materials scientists led by Wen Ma from Inner Mongolia University of Technology, China, reported the first synthesis of hollow rare-earth-containing high-entropy carbides via a one-pot electroreduction process in molten salt at 800 °C. Simply changing the carbon source tailors the architecture from solid to hollow. In 1.0 M KOH, the dual-rare-earth carbide (HfNbTaTiZrCeY)C delivers an overpotential of 167 mV at 10 mA·cm^-2, a Tafel slope of 58.8 mV·dec^-1 and a charge-transfer resistance of 2.7 Ω, outperforming its single-rare-earth counterparts. This work provides a novel strategy for the design of high-performance non-noble metal-based catalysts.

The simultaneous achievement of ultra-high quality factor (Q×f) and near-zero temperature coefficient of resonant frequency (τ_f) remains a critical challenge for microwave dielectric ceramics in 5G/6G systems. Rare-earth vanadate zircon (AVO₄) ceramics are promising for high-frequency applications owing to their intrinsically low dielectric constant, and chemical stability. This work resolves the persistent dilemma between high Q×f and thermal stability in microwave dielectric ceramics, offering a reliable design framework and laying the essential material foundation for advanced microwave components in 5G and 6G networks.

Lensless holographic microscopy replaces imaging optics with computation, but its classical Gabor principle has long been confined to thin, weakly scattering specimens. Researchers at Warsaw University of Technology have now pushed the method into the multiple-scattering regime. Near-infrared illumination preserved resolvable information through tissue-like scattering layers up to 1.4 mm, while increasing the sample-sensor distance unexpectedly doubled lateral resolution—revealing a new acquisition strategy for high-throughput, robust, amplitude-and-phase imaging in complex media.

Respiratory disease in children is a significant public health concern. Conventional assessments require in-person clinic visits and specialized equipment. Smartphones, on the other hand, could be practical for home-based screening. However, existing models trained on electronic-stethoscope data face challenges when applied to smartphone audio. In a new study, researchers developed a domain-adaptive deep learning framework that adapts information from electronic-stethoscope recordings to smartphone audio, supporting smartphone-based abnormal lung sound detection with potential for remote screening.
