This study discovers that tRNA directly binds and regulates the membrane protein FKS1, a β-1,3-glucan synthase essential for fungal cell wall formation. Cryo-EM and biochemical analyses show how tRNA and GSR1 control FKS1 activity and fungal growth.

KP.3.1.1 S S31del confers enhanced immune escape and increased infectivity, which is counterbalanced by NSP10 S33C. The opposing effects of these mutations highlight the complex interplay of viral genomic elements in shaping their overall fitness.

Cryo-EM structures of apo-FKS1 and the FKS1-Rho1 complex reveal how Rho1 activates FKS1, driving conformational changes of FKS1 in β−1,3- glucan synthesis.

SARS-CoV-2 continues to evolve, necessitating updated vaccines and therapeutics. Here the authors identify three broadly binding antibodies from vaccinated or infected individuals, characterize their conserved non-overlapping RBD epitopes by structural analysis and demonstrate protective effects in a hamster model.

Electrofusion enables membrane fusion but struggles with lipid nanoparticles. Here, the authors present a nanofabrication platform that combines microfluidics with microelectrode arrays, achieving efficient, controlled nanoscale electrofusion of LNPs for effective siRNA delivery

Wind is a critical meteorological factor for crop production, yet the effect of its long-term changes on crops has not been adequately discussed. This study reveals that three decades of decreasing wind speed between 1980 and 2010 have enhanced China’s maize production by 101.2 Mt.

On the basis of the assembly mechanism and structures of the human subcortical maternal complex, the authors provide a strategy for the diagnosis of reproductive disorders and the discovery of new infertility-associated SCMC variants.

Here, using cryo-electron microscopy and functional assays in mouse oocytes and embryos, the authors delineate the composition of the subcortical maternal complex, showing that clinical variants associated with female reproductive diseases disrupt complex formation.

Authors present a bispecific antiviral design targeting the virus and the host that simultaneously offers broad-spectrum protection against multiple existing transmissible human-pathogenic coronaviruses, including the Paxlovid-resistant SARS-CoV-2 mutants.

Cryo-EM structures reveal how the first-in-class antifungal drug manogepix inhibits fungal GWT1, a key enzyme for GPI-anchored protein synthesis. The study uncovers manogepix’s competitive binding mechanism and explains drug resistance, offering insights for more effective antifungal therapies.

Here, the authors show that a single mutation in JN.1 spike, L455S, confers better spike cleavage and enhances virus infectivity in differentiated primary human nasal epithelial cells while increasing immune evasiveness, contributing to the efficient spread of JN.1.

This research shows how the bacterial protein DSR2, which protects against phage infection by degrading NAD⁺, is activated by phage protein TTP and inhibited by phage protein DSAD1 through cryo-EM studies and biochemical assays.

Outbreaks of porcine epidemic diarrhea virus (PEDV) have seriously affected pig farms around the world. Here, Li et al. show that PEDV can cause disease in piglets when inoculated by nasal spray, and provide insights into the cellular mechanisms underlying PEDV dissemination within the host.

PfENT1 is a promising antimalarial drug target. Here, authors report cryo-EM structures of PfENT1 that, together with biochemical work, suggests PfENT1 is an inosine transporter and describe the inhibitory mechanism of the endofacial inhibitor, GSK4.

The subcortical maternal complex (SCMC) maintains cleavage of early embryos. Here the authors identify 14-3-3 as a component of the SCMC and show that phosphorylation of TLE6 contributes to 14-3-3 recruitment and stabilization, ensuring mitotic entry in mouse zygotes.

Coronaviruses exploit the host caspase-6 to cleave coronavirus nucleocapsid protein into fragments with interferon-antagonizing activity to facilitate virus replication.

Roughly 10% of Cystic Fibrosis (CF) patients still have no effective medicine to take. Lung Selective Organ Targeting (SORT) Lipid Nanoparticles can efficiently deliver Cas9 mRNA, sgRNA, and donor ssDNA templates for precise homology-directed repair-mediated gene correction in ex vivo and in vivo CF models.

EGFR signalling has been linked to cancer development but whether it has any role in pre-metastatic niche formation is not known. Here the authors show that gastric cancer cells send EGFR through exosomes to the liver where it causes the establishment of a favourable microenvironment thus promoting metastasis.

Cancer-associated fibroblasts (CAFs) have been implicated in lung cancer chemo-resistance. Here the authors show that a zinc-transporter positive CAF subset is enriched in lung cancer models after chemotherapy and actively transfers zinc to cancer cells, promoting ABCB1-mediated chemo-resistance.

The replication and pathogenicity of the Omicron variant of SARS-CoV-2 is attenuated compared with the original strain and other variants.

Soybean and corn production in Brazil increased more than fourfold from 1980 to 2016, which was achieved by double cropping and cropland expansion. The contribution patterns of the two strategies were spatiotemporally specific, while double cropping shows increasing impacts over land expansion to the grain boom.

A phenylboronic acid-modified hetero-octameric Mycobacterium smegmatis porin A nanopore can directly distinguish 11 types of nucleoside monophosphates with a 0.996 accuracy.

Statins have anti-cancer effects that are modulated by the gut commensal Lactobacillus reuteri and the tryptophan metabolite, indole-3-lactic acid, in mice and humans.

Three-dimensional (3D) hydrogel printing enables production of volumetric architectures but achieving good resolutions for miniaturized features remains challenging. Here the authors demonstrate shrinking of a printed structure by immersing a 3D-printed patterned hydrogel consisting of a hydrophilic polyionic polymer network in a solution of polyions of the opposite net charge.

Current recycling methods suffer from harsh reaction conditions and long reaction times. Here the authors show a non-thermal plasma-assisted method for rapid hydrogenolysis of polystyrene at ambient temperature and atmospheric pressure, generating high yield (>40 wt%) of C1–C3 hydrocarbons.

The Microarray Quality Control consortium pitted 36 teams against each other to evaluate methods for creating genomic classifiers, computational tools for interpreting gene expression profiles. The performance of the classifiers on blinded validation data—and metadata on the analytic methods—reveal the challenges facing the field.

Yang Bai and colleagues propose a hypersonic levitation and spinning technique for rapid tissue dissociation. The method enables fast acquisition of high-quality single cells, preserves rare cell types, and supports single-cell sequencing.
