Here, the authors use spot array illumination to enable mechanical-scan-free super-resolution microscopy with adjustable resolution and good effective field of view, demonstrating a platform for studying molecular interactions at the nanoscale.
The principle of Le Chatelier is a fundamental concept in textbooks, serving as a guiding principle for controlling chemical and catalytic systems. In this study, the authors present an oxygen electroreduction system based on a single zinc vacancy catalyst, which operates in a manner that extends “beyond” Le Chatelier’s principle.
Determining the different cell types that contribute to a mixture of DNA is key for research and diagnostic applications. Here, authors comprehensively benchmark DNA methylation-based deconvolution methods, evaluating their performance and robustness to technical bias.
The use of orthogonal genetic code can help to prevent the escape of hazardous genes through horizontal gene transfer. Here, the authors develop a cell-free translation system with the Ser/Leu-swapped genetic code using a hybrid tRNA set and show its application in enhancing the production of superfolder GFP.
The transition between yeast and hyphae is crucial for the pathogenicity of Candida albicans. Here, Liu et al. show that vacuole fusion is active during hyphal extension and that large vacuoles increase the mechanical forces of hyphae penetrating into organs.
The study suggests a positive association between in utero drought exposure and faster biological aging in children in a global climate change hot spot. Drought experienced during pregnancy may reduce life expectancy.
Translocations and copy number variations that affect multiple myeloma (MM) have not been investigated at the single cell level. Here, single cell multi-omics reveal the relationship between epigenetic regulation and cytogenetic events that lead to the increase of cell proliferation in MM.
FOXC1 transcription factor plays a role in vascular development, but its mechanism is not well defined. Here, the authors show FOXC1 regulates retinal angiogenesis by promoting CD98 amino acid transporter expression to activate mTOR signalling, and also by promoting blood-retina barrier formation.
Within the phase diagram of pure substances, the supercritical state is not fully understood. Here the authors experimentally observe a gas-like to liquid-like crossover in the self-dynamics of supercritical fluid methane upon pressure increase.
Traditional methods to incorporate polycrystalline thin film into flexible systems are often complicated and limited by their sizes. Here, the authors introduce flexible amorphous thin film energy harvester, based on perovskite oxides, on a plastic substrate for electromechanical energy harvesting.
The direct C−H-difluoromethylation of pyridines represents a highly efficient economic way to access azines. However, the direct meta-difluoromethylation of pyridines remains elusive. Here, the authors demonstrate switchable meta- as well as para-C−H difluoromethylation of pyridines through radical processes by using oxazino pyridine intermediates.
Previous studies of the skin have suggested a neutral-to-acidic pH gradient in the outermost layer. Here, the authors perform quantitative intravital pH imaging of the stratum corneum, the outermost epidermal layer, and demonstrate three distinct pH zones - rather than a gradient - with different biological functions.
Skeletal ryanodine receptor controls calcium mobilization indispensable for muscle contraction. Here, authors combine cryo-EM and molecular dynamics to uncover the structural basis of the intricate regulation of this channel by calcium and magnesium.
Authors explore the utility of CD5L for treating experimental sepsis. CD5L deficiency exacerbates experimental sepsis. Conversely, administration of recombinant CD5L in WT mice augments neutrophil function, enhances bacterial control, and mitigates inflammation, leading to substantial improvements in disease outcomes.
Controlling multiple stereogenic centers in a single molecular scaffold represents a challenge for current switchable asymmetric catalysts. Here, the authors achieve asymmetric stereodivergency by means of a switchable supramolecular helical catalyst allowing all stereoisomers to be obtained with high and similar enantioselectivities.
Neural circuitry conveying visual information to the medial entorhinal cortex (MEC), a crucial region for spatial cognition, is not fully understood. Here, the authors report a direct pathway from the secondary visual cortex to MEC layer 5a in mice and its involvement in memory-guided navigation, thus revealing a role of deep MEC in sensory information transmission.
The endoplasmic reticulum (ER) is a major site of lipid peroxidation during ferroptosis. Here authors show that the ER protein IRE1α determines ferroptosis induction via regulating glutathione synthesis independent of the unfolded protein response.
Biosensing tools to detect multiple analytes in a high-throughput manner are still hindered by many limitations. Here, the authors present a label-free optofluidic platform integrating digital holography and microfluidics for analyte detection, allowing for the fingerprinting of heterogenous biological samples.
Microbial reduction of nitrous oxide to dinitrogen is considered negligible under acidic conditions. However, Guang He et al. show that a co-culture of two bacterial species derived from acidic tropical forest soil can reduce nitrous oxide at pH 4.5.
Here the authors show that the human transcription elongation factor AF9, part of Super Elongation Complex (SEC), undergoes oligomerization which can be reverted by post-translational modification in regulation of global transcription.
