Succinate dehydrogenase converts malate to enoloxaloacetate, a metabolically inactive and inhibitory side product of the TCA cycle. Here, Zmuda et al. describe a conserved metabolite damage repair enzyme that can remove enol-oxaloacetate and is critical for efficient aerobic respiration.
Achieving genetic circuits on single DNA molecules could have varied applications. Here, authors observed proteins emerging from single DNA molecules through coupled transcription-translation complexes, and show that nascent proteins lingered on DNA, regulating cascaded reactions on the same DNA and allowing the design of a pulsatile genetic circuit.
Hf0.5Zr0.5O2 ferroelectric capacitors undergo a continuous transition from a positive effective to a fully inverted negative piezoelectric coefficient d33 upon electrical cycling. With proper ac training, both the net effective and the local piezoresponses can be nullified while the polarization is kept fully switchable.
A critical challenge of solid-state batteries is Li-filament penetration. Here, by quantifying microstructural properties and employing modeling techniques, the authors provide insight into solid-state battery failure modes and offer design guidelines to enhance safety and performance.
The authors show IRON MAN peptides have an essential role in symbiotic nitrogen fixation during legume-rhizobium symbiosis. The peptides additionally function to regulate nitrogen homeostasis by controlling nitrogen-iron balance.
The Wolbachia cifA and cifB genes generate cytoplasmic incompatibility (CI) in insect hosts but the role of cifA is still debated. Here, the authors report the transgenic recapitulation of CI in the major arbovirus vector Aedes aegypti and provide evidence for cifA inhibiting cifB toxicity in the male germline.
Recombination is essential for life. Here, the authors characterize FLIP as a novel regulator of the key recombination protein RAD51’s functions. FLIP loss caused marked sensitivity to DNA damage, increased DNA breakage and defective replication.
P. Rout et al. study Josephson junctions where the weak link is WSe2-encapsulated bilayer graphene, which features helical edge modes. They argue that the supercurrent channels along opposite edges of the weak link are coupled by a circulating helical mode.
Adaptive tactile interactions transfer across users, space, and time, via embroidered smart gloves is reported by the authors. The scalable fabrication and adaptive computation pipeline enable tactile occlusion alleviation, human skills transfer, and interactive teleoperation.
Gene expression dynamics are tightly regulated during spermatogenesis, with disruptions resulting in infertility. Here they identify a critical role for RNA PolII pausing in spermatogenesis and show that loss of the RNA PolII pausing factor NELF causes meiotic arrest.
Batch effects hinder multi-sample single-cell data analyses. Here, authors present STACAS, a scalable single-cell RNA-seq data integration tool that uses prior cell type knowledge to preserve biological variability, demonstrating robustness to noisy input cell type labels.
Calmodulin-dependent kinase 4 (CaMK4) has been implicated in humoral immunity. Here, the authors demonstrate that CaMK4 expression controls the differentiation of T follicular helper cells, leading to the expansion of pathogenic B cells in systemic lupus erythematosus.
Using All of Us pilot data, the authors compared short- and long-read performance across medically relevant genes and showcased the utility of long reads to improve variant detection and phasing in easy and hard to resolve medically relevant genes.
To optimize the interfacial quality and electrode magnetism in spintronic devices, the authors develop an electrode transfer technique that can greatly improve device interfacial quality, performance and reproducibility, universal to various spacers.
Efforts to produce aromatic monomers through catalytic lignin depolymerization were focused on aryl–ether bond cleavage, while the carbon–carbon bonds of a large fraction of aromatic monomers in lignin are difficult to cleave. Here, the authors report a catalytic autoxidation method using manganese and zirconium salts as catalysts to cleave the C–C bonds in lignin-derived dimers and oligomers from pine and poplar.
Mechanisms occurring during seawater corrosion of as-built laser powder bed fusion 316L stainless steels are largely unknown. Here, the authors show that Mn, Si-rich slags found in between laser tracks are responsible for corrosion.
The ability of living systems to process signals and information is of vital importance. Inspired by nature, Wang and Cichos show an experimental realization of a physical reservoir computer using self-propelled active microparticles to predict chaotic time series such as the Mackey–Glass and Lorenz series.
The presence of CD8+ T cells in the cytoplasm of biliary epithelial cells (BEC) has been associated with primary biliary cholangitis. Here, the authors demonstrate that CD8+ T cells invade BEC using a mechanism that is dependent on cytoskeletal rearrangements and E-cadherin:β-catenin interactions.
Myocardial infarction can lead to malignant arrhythmia and myocardial remodeling. Here, the authors report a microchanneled hydrogel suture for two-way signal communication, pumping drugs on demand, and cardiac repair.
Kidney disease affects more than 850 million people worldwide, but the development of drug therapeutics has been limited by poor mechanistic understanding. Here, the authors perform epigenome-wide analyses to find methylation changes, and disease mechanisms associated with kidney disease.
