Large-scale computational and in vitro analyses identify commensal type III secretion systems and substrates in the human gut microbiome that can interact with human proteins to modulate immune pathways.

Active-site loops are important for catalytic properties of enzymes, but challenging to engineer due to their high flexibility and diversity. Here, the authors identify and engineer hot-spots in the loops of cumene dioxygenase, obtain variants with changed activity, regio- and enantioselectivity, and present a Linker In Loop Insertion approach for loop modification.

Nanoscale carbides provide access to ultra-strong ceramics and show activity as high-performance catalysts. Here, the authors report a flash Joule heating process for the ultrafast, general synthesis of various transition metal carbides nanocrystals with phase controllability.

During development, tissue growth is controlled by coordinated cellular growth and apoptosis. A series of recent papers describes a newly identified Drosophila gene, hippo, that restricts excessive growth during development by both limiting cell cycle progression and promoting susceptibility to apoptosis. Therefore, hippo may coordinate the regulation of cell division and cell death.

Photoredox-catalysed coupling of electron-rich aryl electrophiles based on simple nickel salts usually suffers from a slow oxidative addition. Now, it is shown that thianthrenation leads to more favourable redox properties of the substrates, alleviating this problem in carbon–heteroatom bond-forming reactions.

The addition of molecules on a magnetic film has been known to alter the magnetic properties of the film. Here, through a combination of density function theory calculations, and magnetic force microscopy measurements, Benini and coauthors show the critical importance of long range correlations in the resulting properties of the molecule-decorated magnetic film.

Spin-crossover compounds are molecular switches with functional high- and low-spin states. Here, the authors present an iron(III) complex that additionally also allows for continuous population of both states at low temperatures.

Vanni et al. show a role for microtubules in YAP/TAZ mechanosignalling. Mechanoresponsive microtubule reorganization into centrosomal arrays allows for AMOT delivery to pericentrosomal proteasomes and degradation, leading to YAP/TAZ activation.

How soluble misfolded proteins can bypass chaperones is unknown. Utilizing a meta-analysis, multi-scale modelling, and new experimental data it is found that this phenomena is common and arises from misfolded states that are native-like and long-lived due to protein self-entanglements.

High-surface-area corundum are used in ceramics and catalyst supports, yet the synthesis is hampered by high energy barrier and aggregation. Here the authors report the ultrafast synthesis of corundum nanoparticles via the resistive hotspot triggered phase transformation in electric heating process.

Here the authors use cryo-EM to determine the structures of three bacterial flagellar filaments, revealing distinct outer domains. Upon further analysis of all AlphaFold predicted flagellar outer domains, they show that the outer domains of flagella are highly diverse.

The reduction of N₂ to NH₃ is mediated in living systems by the enzyme nitrogenase and in the chemical industry by the Haber–Bosch process; both systems rely on iron-based catalysis. Now, a molecular tri(iron)bis(nitrido) complex, prepared by reduction of a bis(iron)bis(iodo) precursor under an N₂ atmosphere, has been isolated and shown to promote the formation of NH₃ from H₂.

A time-resolved high-resolution map of human cardiac remodelling after myocardial infarction, integrating single-cell transcriptomic, chromatin accessibility and spatial transcriptomic data, provides a valuable resource for the field.

Transcription factors MarR and MarA confer multidrug resistance in enteric bacteria by modulating efflux pump and porin expression. Here, Sharma et al. show that MarA also upregulates genes required for lipid trafficking and DNA repair, thus reducing antibiotic entry and quinolone-induced DNA damage.

Patel et al. report that Drosophila intestinal stem cell tumours are generated by stress- and EGFR-signalling, followed by extrusion of neighbouring enterocytes, enterocytic cytokine expression and paracrine signalling for tumour growth.

The cardiac vascular niche is of major importance in homeostasis and disease, but knowledge of its complexity in response to injury remains limited. Here we combine lineage tracing with single cell RNA sequencing to show alterations in fibroblasts, endothelial and mural cells in hypertrophic remodeling.

Bleckwehl et al. present a spatial transcriptomic map of atherosclerotic plaques across disease stages, revealing cellular recruitment and migration patterns and intercellular communication dynamics as a valuable resource for future research.

Although immune checkpoint blockade is a standard treatment for patients with malignant mesothelioma, only a minority of patients exhibit radiological response. In a phase II clinical trial (MIST4) investigating the efficacy, safety and molecular correlates of response following treatment with atezolizumab and bevacizumab, the authors demonstrate that the gut microbiota may modulate responsiveness to treatment.

Current oxidative dehydrogenation processes are based on petroleum cracking that is indirect, environmentally unfriendly, and energy intensive. Here, the authors discover that subnanometer sized cobalt oxide clusters are active for oxidative dehydrogenation of cyclohexane at lower temperatures than reported catalysts.

BRCA1–BARD1 directly promotes double-strand break repair by stimulating long-range DNA end resection pathways.

There is increasing evidence of a functional interaction between acute myeloid leukemia (AML) and immune cells, influencing disease outcome. Here the authors study how distinct oncogenes differentially affect the host immune response to leukemic cells in preclinical models of AML.

During early-stage tumour growth in Drosphila, tumour cells acquire necessary nutrients by triggering autophagy in surrounding cells in the tumour microenvironment.

The growth of aortic aneurysms can be predicted via a dimensionless physiomarker, derived from first principles and calculated from data acquired via 4D flow magnetic resonance imaging, that describes a transition from stable blood flow to unstable aortic fluttering.

Using high-resolution multi-omic data from biological wastewater treatment plants, the authors develop a method to forecast microbial community composition and function; the forecasting is accurate for 3 yr into the future.

Flexible neural probes, consisting of a linear array of graphene microtransistors, can be used to record from DC brain signals to high-frequency neuronal activity in awake rodents, thus showing potential for in vivo electrophysiology, and in particular epilepsy research.

Forces transmitted through cell–cell and cell–extracellular matrix adhesions control cell fate decisions. But how are mechanical cues translated into gene expression programmes? The transcriptional regulators YAP and TAZ have arisen as convergence points of mechanical and biochemical signals.

The Hippo signalling pathway is an emerging growth control pathway with roles in organ growth control, stem cell function, regeneration and tumour suppression. Here, Johnson and Halder review the regulation and functions of the Hippo signalling pathway, focusing on its potential to be therapeutically targeted in the treatment of cancer as well as tissue repair and regeneration following injury.

FHR1 is a serum protein implicated in complement regulation. Here the authors show that human FHR1 binds to necrotic cells, triggering inflammasome activation in monocytes in culture, localizes to necrotic tissue and correlates with inflammatory cytokine levels in vasculopathies.

IL1 signalling pathway has been shown to shape cancer associated fibroblast (CAF) heterogeneity. Here the authors identify a pro-tumorigenic CAF subtype in colorectal cancer characterized by high IL1R1 expression and associated with an immunosuppressive tumor microenvironment.

A SARS-CoV-2-human protein contactome map uncovers an inhibitor of viral replication.

The non-Fermi-liquid regime that emerges in MnSi under high pressures displays a Hall signal that can be traced to topologically non-trivial spin configurations at low pressures — a well-understood skyrmion lattice — empirically suggesting a route towards a breakdown of Fermi liquid theory in pure metals.
