A fluorescent probe (NBC), constructed by benzothiazole-coumarin and naphthalimide derivatives, was developed for the detection of SO derivatives using the FRET (Förster Resonance Energy Transfer) strategy. NBC presented large Stokes shift (180 nm), fast response (2 min), high sensitivity (LOD: 45 nM) and an excellent linear relationship in response to SO derivatives. Moreover, NBC has been successfully applied to detect SO derivatives in food samples and living cells.

The development of photoresponsive ferroelastics, which couple light-induced macroscopic mechanical and microscopic domain properties, represents a frontier in materials science with profound implications for advanced functional applications. In this study, we report the rational design and synthesis of two new organic-inorganic hybrid ferroelastic crystals, (MA)(MeN)[Fe(CN)(NO)] (MA = methylammonium) () and (MA)(MeNOH)[Fe(CN)(NO)] (), using a dual-organic molecular design strategy that exploits hydrogen-bonding interactions for tailoring ferroelastic properties. Specifically, exhibits a two-step phase transition at 138 and 242 K, while the introduction of a hydroxyl group in stabilizes its ferroelastic phase to a significantly higher temperature, achieving a phase transition at 328 K, 86 K above that of .

Voice quality serves as a rich source of information about speakers, providing listeners with impressions of identity, emotional state, age, sex, reproductive fitness, and other biologically and socially salient characteristics. Understanding how this information is transmitted, accessed, and exploited requires knowledge of the psychoacoustic dimensions along which voices vary, an area that remains largely unexplored. Recent studies of English speakers have shown that two factors related to speaker size and arousal consistently emerge as the most important determinants of quality, regardless of who is speaking.

3D disordered fibrous network structures (3D-DFNS), such as cytoskeletons, collagen matrices, and spider webs, exhibit remarkable material efficiency, lightweight properties, and mechanical adaptability. Despite their widespread in nature, the integration into engineered materials is limited by the lack of study on their complex architectures. This study addresses the challenge by investigating the structure-property relationships and stability of biomimetic 3D-DFNS using large datasets generated through procedural modeling, coarse-grained molecular dynamics simulations, and machine learning.

Avian genomes exhibit compact organization and remarkable chromosomal stability. However, the extent and mechanisms by which structural variation in avian genomes differ from those in other vertebrate lineages are poorly explored. This study generated a diploid genome assembly for the golden pheasant ( ), a species distinguished by the vibrant plumage of males.
