The flexibility and programmability of CRISPR-Cas technology have made it one of the most popular tools for biomarker diagnostics and gene regulation. Especially, the CRISPR-Cas12 system has shown exceptional clinical diagnosis and gene editing capabilities. Here, we discovered that although the top loop of the 5' handle of guide RNA can undergo central splitting, deactivating CRISPR-Cas12a, the segments can dramatically restore CRISPR function through nucleic acid self-assembly or interactions with small molecules and aptamers.

Dilated cardiomyopathy (DCM) is the ultimate manifestation of the myocardial response to various genetic and environmental changes and is characterized mainly by impaired left ventricular systolic and diastolic function. DCM can ultimately lead to heart failure, ventricular arrhythmia (VA), and sudden cardiac death (SCD), making it a primary indication for heart transplantation. With advancements in modern medicine, several novel techniques for evaluating myocardial involvement and disease severity from diverse perspectives have been developed.

Electrochemical oxidation of small molecules shows great promise to substitute oxygen evolution reaction (OER) or hydrogen oxidation reaction (HOR) to enhance reaction kinetics and reduce energy consumption, as well as produce high-valued chemicals or serve as fuels. For these oxidation reactions, high-valence metal sites generated at oxidative potentials are typically considered as active sites to trigger the oxidation process of small molecules. Isolated atom site catalysts (IASCs) have been developed as an ideal system to precisely regulate the oxidation state and coordination environment of single-metal centers, and thus optimize their catalytic property.

Lithium dendrite penetration through solid electrolyte has been the major obstacle for practical sulfide-based all-solid-state lithium metal batteries (ASSLMBs). Herein, a series of tailored model solid cells are designed to investigate the intrinsic lithium growth behavior at open surfaces and internal cracks of sulfide solid electrolyte. It is shown that when plating lithium on the open surface of electrolyte (free space), the lithium exhibits an intrinsic columnar growth behavior perpendicular to the electrolyte surface, preferentially along the (110) crystal axis.

Microfluidic-Enabled Self-Directed Hydrogel Microspheres for Multiplexed MicroRNA Assays.

Anal Chem

January 2025

MOE Key Laboratory of Geriatric Nutrition and Health, Department of Bioengineering, Beijing Technology and Business University, Beijing 100048, China.

Multiplexed microRNA (miRNA) detection has proven valuable in disease diagnosis; yet, the development of advanced tools for their analysis remains a subject of broad interest. Here, we propose a novel single-particle method for multiplexed miRNA detection using self-directed hydrogel microspheres, which feature supersegmented compartments for loading analyte probes and an air-encapsulated region that grants the microsphere a unique preferred posture in aqueous solutions. By exploiting microfluidic technology, we can widely adjust the size of the microspheres and the number of compartments can be widely adjusted.

The L2 Motivational Self System (L2MSS) determines an individual's motivation in second language learning and influences the learning experience and intended effort. Although physical activity (PA) has been shown to enhance academic efficacy, the role of PA in whether it promotes second language learning efficacy has not been elucidated. Therefore, the present study examined PA as a mediator and explored its ameliorative effects in L2MSS.

Equity is a cornerstone of global climate policy, yet differing perspectives mean that international agreement on how to allocate mitigation efforts remains elusive. A rich literature informs this question, but a gap remains in approaches that appropriately consider non-CO emissions and their warming contributions. In this study, we address this gap and define a global warming budget applicable to all anthropogenic greenhouse gases that is allocated to countries based on principles drawn from international treaties and environmental law.

Institute of Atmospheric Environment, Chinese Academy of Environmental Planning, Beijing 100012, China; Center of Synergistic Control for Reducing Pollution and Carbon Emissions, Chinese Academy of Environmental Planning, Beijing 100012, China. Electronic address:

To address the concern of optimization problem of China's PM control and the limitation of computational efficiencies for traditional air quality models, we developed an integrated analysis framework to efficiently establish the identification and cost-benefit assessment of PM control pathways in China by constructing a rapid PM exposure response method based on the high-order decoupled direct method (HDDM) and coupling the sequential least square algorithm (SLSQP) and health impact assessment model. Six emission reduction scenarios with varying decision preferences were analyzed. Our study provides a methodological approach for the rapid optimization of emission pathways of major air pollutants in China with flexible options in terms of objectives and constraints, fully considering the diverse differences in environmental, health, and economic impacts among different pollution sources simultaneously.
