Switchable porous materials offer adaptive voids mutating in size and shape in response to molecular stimuli. Here authors use PFG NMR to reveal the decisive role of metastable states leading to counterintuitive negative gas adsorption transitions in responsive MOFs.
Voltage-gated sodium (Nav) channels are targeted by various clinically applied and investigational drugs. Here cryo-EM structures of Nav1.7 bound to 7 compounds with diverse chemical skeletons reveal the structural basis of action of these drugs and provide a 3D structural map for drug binding sites on Nav channels.
Smart windows offer more efficient sunlight modulation and heat management. Here, the authors propose a co-assembly strategy to produce smart windows that combine electrochromic and thermochromic functions with tunable components and ordered structures for dynamic solar radiation regulation.
In a magneto-electric material, the magnetic and electric properties are coupled. This coupling allows the magnetic order to be controlled by electric stimuli, making magnetoelectric materials promising candidates for new data storage technologies. Here Gu et al demonstrate a magnetoelectric effect in a van der Waals antiferromagnetic CrOCl which persists down to monolayer, and using this realize a multi-state data storage device.
Cooperative disease defense is part of group-level collective behavior. Here, the authors explore individual decisions, finding that garden ants increase grooming highly infectious individuals when they perceive a high pathogen load and suppress grooming after having been groomed by nestmates.
There is limited understanding of SARS-CoV-2 intra-host evolution and subsequent transmission and adaptations in the context of persistent infection. Here, the authors describe sequential persistent SARS-CoV-2 infections that led to the emergence, transmission and further evolution of a novel Omicron BA.1.23 lineage.
Previous studies have shown that high alcohol-producing Klebsiella pneumoniae (HiAlc Kpn) in the intestinal microbiome could be one of the causes of non-alcoholic fatty liver disease (NAFLD). Here, the authors show the effectiveness of phage in mice with HiAlc Kpn-induced NAFLD indicating phage therapy targeting gut microbiota may be an alternative to antibiotics, with potential efficacy and safety.
Disorder crystallization of perovskite and unbalanced charge extraction limit the performance of perovskite solar cells. Here, the authors develop self-polymerizing additive to form monolithic perovskite grains with mortise-tenon structure, achieving efficiency over 24% and long device stability.
The authors propose a confocal complemented signal-object collaborative regularization method for non-line-of-sight (NLOS) imaging without specific requirements on the spatial pattern of measurement points. The method extends the application range of NLOS imaging.
Arising from contact electrification and electrostatic breakdown, DC triboelectric nanogenerators are a promising solution to the air breakdown bottleneck in conventional TENGs. Here, authors reveal and regulate three discharge domains enhancing the device output power by an order of magnitude.
Lysophosphatidic acid is known to increase in concentration in multiple cancer types. Here, the authors show it affects CD8 T cell metabolism, phenotype, and effector functions, and plasma concentrations appear predictive of response to immunotherapy.
gem-Difluorinated motifs are prevalent in numerous leading pharmaceuticals. Here the authors merge I(I)/I(III)-catalysed fluorination and C(sp3)-F bond activation to generate these motifs directly from 1,3-diaryl cyclobutanols in a single operation.
The WNT/b-catenin pathway is essential for bloodbrain barrier (BBB) and blood-retina barrier (BRB) function. A bioengineered FZD4-selective WNT surrogate demonstrated systemic efficacy during BRB and ischemic stroke BBB dysfunction in mice.
Seasonal stratification on the northwest European Shelf is found to be triggered by rainfall from passing storms. Further links are made between the onset of stratification to large-scale pressure changes in the North Atlantic.
Bilayer graphene (BLG) is promising for optoelectronic applications due to its tunable bandgap, but its large-area growth on Cu substrates is still challenging. Here, the authors demonstrate the fast synthesis of high-coverage meter-scale BLG on commercial Cu foils by introducing CO2 during the growth.
This study provides evidence that two RhoGEF isoforms displaying distinct localisation concurrently modulate Rho1 activity to promote robust furrow ingression while preserving cell size asymmetry during neural stem cell division.
Metal-thiolate complexes are the precursors to atomically precise metal nanoclusters. Here, the authors show that the extent of metal-ligand interaction is key to controlling the size and uniformity in the synthesis of metal nanoclusters.
The neural mechanisms underlying the beneficial effects of behavioural training in combination with transcranial direct current stimulation (tDCS) are not well understood. Here, the authors combine cognitive training with tDCS, showing a modulation of prefrontal white and grey matter microstructure, and increased prefrontal functional connectivity.
Here, the authors assess performance and limitations to polygenic risk scores in different race/ethnic groups. They find that polygenic risk score performance improves with diverse training data, and a better understanding of varying genetic backgrounds, social and environmental factors, and gene-environment interactions, is needed to enhance PRS performance for all groups.
The transcriptional regulation of mitochondrial oxidative phosphorylation gene expression is poorly understood. Using the developing Drosophila flight muscle, the authors identify the transcription factor M1BP as a new major regulator of this process.
