Cells must  adapt to environmental changes. Here, the authors show that TM9SF3 mediates PIP₂ translocation in response to extracellular acidification,  thereby regulating cell migration through cytoskeletal remodelling.

Analysis of the blood DNA virome in patients with COVID-19 and autoimmune disease associates endogenous HHV-6 (eHHV-6) and high anellovirus load with increased disease risk, most notably for systemic lupus erythematosus. eHHV-6 carriers show a distinct immune response.

Genetic mechanisms influencing COVID-19 susceptibility are not well understood. Here, the authors analyzed whole blood RNA-seq data of 465 Japanese individuals with COVID-19, highlighting thousands of fine-mapped variants affecting expression and splicing of genes, as well as the presence of COVID-19 severity-interaction eQTLs.

The XRISM Resolve spectrum of the galactic neutron star X-ray binary, GX 13+1, reveals one of the densest winds ever seen in absorption lines.

Resistance to EGFR tyrosine kinase inhibitors (EGFR-TKIs) is prevalent. Here the authors establish a biobank of patient-derived EGFR-mutant lung cancer organoids and identify a subgroup of EGFR-TKI-resistant lung adenocarcinoma organoids, which exhibit a basal-shift phenotype and vulnerability to CDK4/6 inhibitors.

On the basis of the whole-genome sequences of cultivated and wild hops, this study describes the evolution of sex chromosomes, including degeneration and dosage compensation, and identifies a candidate gene for the X–A balance sex-determination system in these species.

The P681R mutation in the spike protein renders the Delta variant more pathogenic than prototypic SARS-CoV-2 in infected hamsters, and facilitates spike protein cleavage and enhances viral fusogenicity.

Peripheral blood mononuclear cells from 73 Japanese patients with coronavirus disease 2019 (COVID-19) and 75 healthy controls were analyzed using single-cell transcriptomics. Combining these data with genotyping data highlights the interplay between host genetics and the immune response in modulating disease severity.

Using more than 100 independent iPSC lines derived from patients with Alzheimer’s disease, the authors discovered loci associated with the neuronal production of amyloid β and confirmed their influence using RNA interference.

Watanabe et al. show that cytopathic hypoxia, through upregulation of COX2 and secretory PLA2, stabilizes HIF-1α, contributing to impaired mitochondrial respiration and reduced cardiac contraction in septic cardiomyopathy.

Geometrical confinement in ultrathin 0.68PbMg_1/3Nb_2/3O₃-0.32PbTiO₃ films induces a dome-shaped stability region of relaxor behaviour in a temperature–thickness relaxor phase diagram.

Molecular rotors have seen considerable interest as functional molecules on surfaces or for applications as memory devices. However, it is now shown that molecular rotation may also be used to induce ferroelectricity in a molecule.

XBB is the first recombinant, globally dominant variant of SARS-CoV-2. Here, the authors examine the variant’s origins and virological properties, showing it is the first example of SARS-CoV-2 improving its fitness through recombination.

The spike protein of the Omicron variant of SARS-CoV-2 has a higher affinity for ACE2 than Delta, and a marked change in its antigenicity increases Omicron’s evasion of therapeutic and vaccine-elicited neutralizing antibodies.

Sato and colleagues present a biobank of patient-derived SCLC organoids, conducting a comprehensive genome and transcriptome profiling that reveals the existence of NE and non-NE subtypes with distinct molecular dependencies.

Seed dormancy allows wild barley grains to survive dry summers in the Near East but has been selected against for industrial applications such as beer and whisky production that require quicker germination. Here Sato et al. show that Qsd1is a major seed dormancy gene in barley and encodes an alanine aminotransferase.

One area of interest in the field of molecular magnetism is the development of high-spin molecules. Here, the authors report a cyanide-bridged nanocage consisting of 18 high-spin iron(III) ions ferromagnetically coupled through 24 low-spin iron(II) ions, with a ground state spin of S=45.

Knowledge of hydrogen content and coordination in deuterized metals is of importance. Here, the authors study the deuterization of face-centred cubic iron in-situvia neutron diffraction, observing the occupation by hydrogen of both octahedral and tetrahedral interstitial sites.

In vitro studies in human cell lines and in vivo studies in a hamster model show that the SARS-CoV-2 Omicron variant is less pathogenic than both the Delta variant and an ancestral strain of SARS-CoV-2.

Though dynamics of molecules are generally restricted by intermolecular contacts, C₆₀ fullerene is able to rotate freely despite being tightly bound inside a molecular host. Here, the authors study the solid-state dynamics of this host-guest system to understand the anomalous relationship between tight association and low friction.

Replacing carbon atoms in nanocarbons with heteroatoms alters their intrinsic properties, and nitrogen-doped nanocarbons attract much attention in various fields. Here, the authors synthesize a discrete nitrogen-doped nanotube molecule and clarify its structure to reveal unique features of nitrogen dopants.

XBB.1.5 of SARS-CoV-2 is a descendant of XBB.1 and has mutations in spike and ORF8, making it more infectious to humans. Here, the authors examined in detail the differences in virological properties of the two variants.

Observations of a luminous quasar from the high-resolution spectrometer Resolve aboard XRISM revealed highly inhomogeneous wind structure outflowing from a supermassive black hole, which probably consists of up to a million clumps.

Non-basaltic volcanism is rare on the Moon and has been found predominantly on the lunar nearside. Analysis of Lunar Reconnaissance Orbiter Camera images and spectral data reveal the presence of compositionally evolved, non-basaltic volcanism on the lunar farside.

An acellular, bioresorbable, ultra-purified alginate gel implantation system to prevent lumbar intervertebral disc (IVD) degeneration after discectomy demonstrated its feasibility and safety in phase 1/2 clinical trials for herniated intervertebral disc degeneration.

Description of the cryo-EM structures of the parathyroid hormone type 1 receptor associated with G_q reveals two distinct extracellular conformations with N-glycans stabilizing a ligand-tilted conformation.

The authors report a transcriptional profile of the discrete stages of spontaneous remyelination following toxin-induced focal demyelination in rats. They find an enrichment of retinoid X receptor (RXR) signaling pathways over the course of remyelination and show that RXR activation stimulates oligodendrocyte differentiation to enhance remyelination.
