Quantum fluctuations influence direction-dependent electrical transport in chiral magnets, report researchers from Science Tokyo. In chiral magnetic systems, electric current flows differently depending on its direction, but the role of quantum effects in this behavior has remained unclear. Through theoretical analysis, the researchers showed that chiral magnetic systems exhibit logarithmic temperature dependence at low temperature, offering new insights into electron transport in magnetic materials. These findings are expected to play a crucial role in spintronics.

Hybrid quantum sources are essential for developing large-scale quantum networks. However, heterogeneous single-photon sources have different spectral and temporal networks, necessitating modifications and synchronizations that lead to losses and the need for additional resources. In a new study, researchers have successfully achieved indistinguishable photon generation between two physically dissimilar quantum sources: warm atomic ensembles and quantum dots. The two sources also demonstrated high visibility two-photonic interference, marking a key step for future quantum networks.

How much load can a crumpled sheet bear, and does size matter? A new study of two-dimensional macromolecules, a class of ultrathin sheet-like materials, shows that at equal packing density smaller sheets carry higher compressive loads than larger ones. Coarse-grained simulations and compression tests on paper, aluminum foil, PDMS, and silicone rubber reveal a universal “smaller is stronger” rule rooted in denser internal ridge networks, offering a new design principle for lightweight, high-strength structural metamaterials.

This review summarizes recent advances in wearable uric acid sensors, covering electrochemical and optical detection mechanisms, performance-enhancement strategies, device integration, and emerging applications. It highlights progress in sensitivity, selectivity, anti-fouling performance, self-calibration, and user comfort, while identifying persistent challenges in long-term stability, interference resistance, multimodal monitoring, clinical validation, data security, and commercialization. Future directions emphasize intelligent, sustainable, and personalized sensing platforms.

By sending quantum information through a storm, researchers at The University of the Witwatersrand in Johannesburg, South Africa, have shown that the information in light can be kept completely intact, even though the light itself was completely warped beyond recognition. 

An international team of researchers from École Polytechnique, Collège de France, and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal (PTC), a material whose optical properties can be strongly and periodically modulated in time at ultrafast scales.

Published in Journal of Bioresources and Bioproducts, the review systematically summarizes recent advancements in multifunctional paper-based smart packaging. It highlights core modification strategies—internal additive incorporation, impregnation, coating, surface functionalization, and layer-by-layer assembly—that transform paper from passive protection into active regulation and intelligent sensing platforms. The authors discuss matrix-specific synergistic systems tailored to fresh produce and high-protein foods, while critically analyzing challenges including the recyclability paradox of high-performance coatings, unpredictable migration safety, and the scalability gap between laboratory innovation and industrial production.

A research team led by Prof. MENG Guowen and Prof. HAN Fangming from the Institute of Solid State Physics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, in collaboration with Prof. WEI Bingqing from the University of Delaware, has developed a highly crystalline three-dimensional graphitic carbon tube grid (3D-GCTG) that significantly improves the performance of filtering supercapacitors with thick electrodes.

Three-dimensional atomic arrangements in nanoscale regions are essential information for the development of nanoscale devices and novel functional materials. Until now, however, there has been no method for observing them directly. In this study, the researchers developed an atom-holography microscope that measures a hologram from the region irradiated with a finely focused electron beam and performs holographic reconstruction to directly visualize the three-dimensional atomic arrangement. Because the microscope enables three-dimensional atomic arrangements in nanoscale regions to be measured anywhere, it is expected to be useful in the analysis of nanoscale devices and the development of novel functional materials.
