Background: The advancements in second-/third-generation sequencing technologies, alongside computational innovations, have significantly enhanced our understanding of the genomic structure of Y-chromosomes and their unique phylogenetic characteristics. These researches, despite the challenges posed by the lack of population-scale genomic databases, have the potential to revolutionize our approach to high-resolution, population-specific Y-chromosome panels and databases for anthropological and forensic applications.
Objectives: This study aimed to develop the highest-resolution Y-targeted sequencing panel, utilizing time-stamped, core phylogenetic informative mutations identified from high-coverage sequences in the YanHuang cohort.

Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases. Given the multifactorial pathophysiology of AD, monotargeted agents can only alleviate symptoms but not cure AD. Acetylcholinesterase (AChE) and Monoamine oxidase B (MAO-B) are two key targets in the treatment of AD, molecules that inhibiting both targets are considered promising avenue to develop more effective AD therapies.

(K,Na)NbO-based ceramics are deemed among the most promising lead-free piezoelectric materials, though their overall piezoelectric performance still lags behind the mainstream lead-containing counterparts. Here, we achieve an ultrahigh piezoelectric charge coefficient d ∼ 807 pC·N, along with a high longitudinal electromechanical coupling factor (k ∼ 88%) and Curie temperature (T ∼ 245 °C) in the (K,Na)(NbSb)O-BiNaZrO-BiFeO (KNN-xSb) system through structural flexibility and grain orientation strategies. Phenomenological models, phase field simulations and high-angle annular dark-field scanning transmission electron microscopy reveal that the structural flexibility originates from the high Coulomb force between K/Na ions and Sb ions in the KNN-xSb system, while the grain orientation promotes the displacement of B-site cations leveraging the engineered domain configuration.

Ceramic capacitors with ultrahigh power density are crucial in modern electrical applications, especially under high-temperature conditions. However, the relatively low energy density limits their application scope and hinders device miniaturization and integration. In this work, we present a high-entropy BaTiO-based relaxor ceramic with outstanding energy storage properties, achieving a substantial recoverable energy density of 10.

Lactoferrin protein (LF) is a natural protein with certain emulsifying ability, but is sensitive to be affected by environmental factors and has poor oxidative stability to be used as emulsifier. In this study, the emulsifying ability of LF was significantly improved after conjugation with Rosa roxburghii Tratt fruit polysaccharides (RTFP), and the emulsion stability mechanism of LF-RTFP conjugates (L-R) were elucidated through the utilization of CLSM (confocal laser scanning microscopy), interfacial tension, apparent viscosity, and protein adsorption rate. The emulsion stabilized by L-R showed the smaller particle size (17.
