Enriched Electrophilic Oxygen Species on Ru Optimize Acidic Water Oxidation.

Ruthenium oxide (RuO) is considered one of the most promising catalysts for replacing iridium oxide (IrO) in the acidic oxygen evolution reaction (OER). Nevertheless, the performance of RuO remains unacceptable due to the dissolution of Ru and the lack of *OH in acidic environments. This paper reports a grain boundary (GB)-rich porous RuO electrocatalyst for the efficient and stable acidic OER.

Regulation of Shade Avoidance Under Low-Blue-Light by MTA in Soybean.

Under low blue light (LBL) conditions, soybean exhibits classic shade avoidance syndrome (SAS) with exaggerated stem elongation (ESE), leading to lodging and yield reduction in dense farming. Recently, mRNA modification by N6-methyladenosine (m6A) has emerged as a crucial epigenetic mechanism regulating plant biological processes; however, its impact on shade avoidance remains unexplored. In this study, the double mutants, gmmtas, that are impaired in two mA writer genes, GmMTAa and GmMTAb that encode mA methyltransferases or mA writers are generated.

Automated programming approaches to enhance computer-aided translation accuracy.

With the continued development of information technology and increased global cultural exchanges, translation has gained significant attention. Traditional manual translation relies heavily on dictionaries or personal experience, translating word by word. While this method ensures high translation quality, it is often too slow to meet the demands of today's fast-paced environment.

Genome-wide association study and transcriptome analysis reveal the genetic basis underlying the environmental adaptation of plant height in a woody plant.

Studies on plant height have been conducted in several crops. However, the underlying genetic mechanisms in woody plants remain unclear. To improve the genetic understanding of plant height, the genome-wide association study (GWAS) was conducted on the 298 individuals of paper mulberry (Broussonetia papyrifera), and the individuals with the highest and lowest plant heights were selected for comparative transcriptome analysis.

Evolutionary dynamics and functional characterization of proximal duplicated sorbitol-6-phosphate dehydrogenase genes in Rosaceae.

Sorbitol is a critical photosynthate and storage substance in the Rosaceae family. Sorbitol 6-phosphate dehydrogenase (S6PDH) functions as the pivotal rate-limiting enzyme in sorbitol synthesis. The origin and functional diversification of S6PDH in Rosaceae remain unclear, largely due to the complicated interplay of gene duplications.

Quantum dot-based biomimetic fluorescence immunoassays for enrofloxacin detection in animal-derived foods.

Long-term consumption of foods with excessive enrofloxacin (ENRO) residues may cause the accumulation of ENRO in the human body, thus damaging human health. In this study, quantum dot-based biomimetic fluorescence immunoassays were used for enrofloxacin detection in food of animal origin. Under the most suitable conditions, the detection limit (IC) of the method in standard solution was 0.

Creeping Stem 1 regulates directional auxin transport for lodging resistance in soybean.

Soybean, a staple crop on a global scale, frequently encounters challenges due to lodging under high planting densities, which results in significant yield losses.

Methods: Sixty patients with acute myocardial infarction (AMI) and 60 cases with chronic coronary syndrome (CCS) were enrolled.

Phylogenomic Analysis and Functional Characterization of the APETALA2/Ethylene-Responsive Factor Transcription Factor Across Solanaceae.

The AP2/ERF family constitutes one of the largest groups of transcription factors in the Solanaceae. AP2/ERF contributes to various plant biological processes, including growth, development, and responses to various stresses. The origins and functional diversification of AP2/ERF within the Solanaceae family remain poorly understood, primarily because of the complex interactions between whole-genome duplications (WGDs) and tandem duplications.

π-Conjugation-Induced In Situ Nanoscale Ordering of Spiro-OMeTAD Boosts the Efficiency and Stability of Perovskite Solar Cells.

Spiro-OMeTAD hole transport materials typically exhibit an amorphous state in perovskite solar cells. However, the lack of structural ordering leads to weak intermolecular interaction, inferior carrier transfer, and poor stability in devices. Herein, we developed a π-conjugation-induced short-range ordering strategy to modulate the stacking order of spiro-OMeTAD during film formation.

Xylan-based full-color room temperature phosphorescence materials enabled by imine chemistry.

Developing sustainable matrix and efficient bonding mode for preparing room temperature phosphorescence (RTP) materials with full-color afterglows is attractive but still challenging. Here, xylan, a hemicellulose by-product from the paper mill, is used to construct full-color RTP materials based on imine bonds. Xylan is oxidation by periodate to introduce aldehyde groups to increase reaction sites; aromatic amines with different π conjugations can be readily anchored to dialdehyde xylan (DAX) by imine chemistry.

Interplay between acetylation and ubiquitination controls PSAT1 protein stability in lung adenocarcinoma.

Serine is essential to maintain maximal growth and proliferation of cancer cells by providing adequate intermediate metabolites and energy. Phosphoserine aminotransferase 1 (PSAT1) is a key enzyme in de novo serine synthesis. However, little is known about the mechanisms underlying PSAT1 degradation.

This study aims to investigate alterations in resting-state brain networks in adolescents with IGD and the potential neurobiological mechanisms underlying cognitive dysfunction.

Multifunctional Radiation Conditioning Emitter for Laser and Infrared with Adaptive Radiative Cooling.

With the development of technology, multifunctional multiband emitters have been paid much attention due to their wide range of applications, such as LIDAR detection, spectroscopic sensing, and infrared thermal management. However, the development of such emitters is impeded by incompatible structural requirements of different electromagnetic wavebands. Here, we demonstrate coupled modulation between near-infrared (NIR) laser-wavelength and long-wavelength-infrared by constructing a multifunctional emitter (MFE) with a structure of Al/HfO/VO, utilizing the phase transition of VO.

Precision Propargylic Substitution Reaction: Pd-Catalyzed Suzuki-Miyaura Coupling of Nonactivated Propargylamines with Boronic Acids.

Palladium-catalyzed Suzuki-Miyaura cross-coupling is an efficient approach for C-C bond construction. Here we report a deaminative Suzuki-Miyaura reaction to achieve chemo- and regioselectivity in the cross-coupling of nonactivated propargylamines with boronic acids, in which methyl propiolate is introduced to promote the cleavage of the C-N bond to form the C-C bond. This method features a wide range of substrates, good functional group tolerance, and ease of operation, providing an alternative approach to accessing valuable propargylated aromatic compounds.

The Importance of Digital Lung Tomosynthesis in Overcoming Computed-Tomography-to-Body Divergence During Bronchoscopic Biopsies of Peripheral Lung Nodules.

The advent of robotic bronchoscopy coupled with electromagnetic navigation bronchoscopy (EMN) and shape-sensing technology have increased diagnostic yields for peripheral pulmonary nodules compared to traditional bronchoscopy. Yet, diagnostic yields from these bronchoscopic platforms still fall short of where they should be. This shortfall is in large part due to a lack of advanced imaging during peripheral bronchoscopy and computed tomography (CT)-to-body divergence (CTBD).

Isolation and Characterization of Potassium-Solubilizing Rhizobacteria (KSR) Promoting Cotton Growth in Saline-Sodic Regions.

Cotton is highly sensitive to potassium, and Xinjiang, China's leading cotton-producing region, faces a severe challenge due to reduced soil potassium availability. Biofertilizers, particularly potassium-solubilizing rhizobacteria (KSR), convert insoluble potassium into plant-usable forms, offering a sustainable solution for evergreen agriculture. This study isolated and characterized KSR from cotton, elucidated their potassium solubilization mechanisms, and evaluated the effects of inoculating KSR strains on cotton seedlings.
