Sichen Zhang et al.
Aging in females is characterized by dysfunctional ovaries (DOs). While human umbilical cord mesenchymal stem cell (HucMSC)-derived extracellular vesicles (EVs) have shown promise in ameliorating DO, the mechanisms underlying their effects ...
Disentangling participation in online political discussions with a collective field experiment [0.03%]
利用集体现场实验的方法探究线上政治讨论参与度的影响因素

Online political discussions are often dominated by a small group of active users, while most remain silent. This visibility gap can distort perceptions of public opinion and fuel polarization. Using a collective field experiment on Reddit,...
Evaluating the effects of archaic protein-altering variants in living human adults [0.03%]
评估_archaic_蛋白质改变变异在活着的成人人体内的作用效应
Barbara Molz,Mikel Lana Alberro,Else Eising et al.
Barbara Molz et al.
Advances in paleogenetics allowed the identification of protein-coding changes unique to Homo sapiens by comparing present-day and archaic hominin genomes. So far, experimental validation has been restricted to functional assays and model o...
Unlocking megawatt-peak-power laser emission with colloidal quantum dots [0.03%]
解密兆瓦级峰值功率激光发射的胶体量子点技术
Yuting Wu,Hancheng Zhu,Zhigao Huang et al.
Yuting Wu et al.
Output power of a laser device critically defines the application prospects. Colloidal quantum dots (QDs) have emerged as auspicious laser media; however, the exclusively low-power emission obscures the practical deployment. Here, we resolv...

Schistosomes, parasitic flatworms responsible for the neglected tropical disease schistosomiasis, are protected by a skin-like tegument, and tegument maintenance is controlled by a schistosome ortholog (p53-1) of the tumor suppressor TP53. ...
Deep-blue light-emitting diodes based on perovskite single-crystal thin films [0.03%]
基于钙钛矿单晶薄膜的深蓝色发光二极管
Danlei Zhu,Yifan Zhou,Xu Wen et al.
Danlei Zhu et al.
Metal halide perovskite light-emitting diodes (LEDs) are transformative optoelectronic platforms due to their tunable emission, high color purity, and broad color gamut. Nevertheless, the realization of high-luminance blue LEDs, particularl...
Outcompeting hydrofunctionalization: Asymmetric remote substitution of alkynes [0.03%]
超越氢官能团化反应:炔烃的不对称远程取代反应
Yi-Xiao Shen,Chao Ma,Guo-Qiang Lin et al.
Yi-Xiao Shen et al.
Propargylic substitution is a broadly studied basic reaction but requires a vicinal leaving group in the alkyne substrate. Here, we describe the first asymmetric remote substitution of alkynes bearing a linear alkyl-linked remote leaving gr...
Insect-inspired micro-optical antenna enables ultrasensitive multisensory perception [0.03%]
昆虫启发的微光学天线实现超灵敏多模感知

Xitao Tu et al.
Insects have evolved highly optimized antennae with ultrasensitive tactile, auditory, and olfactory senses. Although imitating insect antennae offers a promising route to achieving advanced sensing abilities, developing a micro-sized artifi...
A mechano-gated ionic diode enables low-power synaptic tactile spiking [0.03%]
机械门控离子二极管实现低功耗突触体感触发脉冲
Yong Min Kim,Hanbin Choi,Ji Hong Kim et al.
Yong Min Kim et al.
Ionic diodes, which enable unidirectional ion transport, hold great promise for adaptive and energy-efficient ionotronic systems. However, conventional designs often rely on high ion concentrations, which promote ion pairing and clustering,...
