Dermatoscopy is a common method to aid in diagnosis of melanoma, however, its utility in predicting metastasis is not fully known. Here, the authors leverage a cohort of 30 dermatologists to develop models to predict prognosis from dermatoscopic images.

Religious decline is happening around the world. Here, the authors show that countries are at different stages of a common global sequence of decline in religious participation, personal importance of religion, and religious belonging.

Autophagosome tethering compounds (ATTECs) are small molecule degraders hijacking the autophagy system. Here, the authors show that current ATTEC ligands did not bind to their designated targets but establish good ligandability of ATG8 isoforms through fragment screening and docking.

Spin-momentum locking is a fundamental property of condensed matter systems. Here, the authors evidence parallel Weyl spin-momentum locking of multifold fermions in the chiral topological semimetal PtGa.

Altered redox biology causes mitochondrial dysfunction, yet mechanisms and implications vary. Here, the authors identify 15 lipoxygenase-linked mitochondrial ferroptosis and mitophagy driving epithelial cell differentiation and asthma outcomes.

Chromosomal instability (CIN) is a common feature of colorectal cancer cells and several mechanisms have been suggested for CIN generation. Bastians and colleagues find that increased microtubule plus-end stability can be triggered by AURKA overexpression and is associated with abnormal spindles and lagging chromosomes in colorectal cancer cells.

Two new phosphorylation sites, p-tau₂₆₂ and p-tau₃₅₆, detect the formation of prefibrillar tau aggregates and may serve as early-stage biofluid-based biomarkers of tau neurofibrillary tangle pathology in Alzheimer’s disease.

Schizophrenia research has traditionally overlooked sex differences. Here, the authors show the importance of sex-based analysis across multi-brain regions by identifying sex-specific genes and genetic interactions in schizophrenia and sex-specific risk.

Human affect is shaped in part by whether desirable states are achieved under personal control. Here, the authors show that control beliefs affect happiness and pride, and how those effects relate to neural responses in the prefrontal cortex and behavioral preferences for exerting control.

Studying gene expression in admixed Black Americans, Benjamin et al. reveal genetic ancestry-linked differences impacting immune and vascular genes and potentially influencing neurological disease risk. These findings highlight the importance of considering ancestry in brain research.

In a cynomolgus macaque model, CRISPR base editors delivered in lipid nanoparticles are shown to efficiently and stably knock down PCSK9 in the liver to reduce levels of PCSK9 and low-density lipoprotein cholesterol in the blood.

Expansion microscopy with gel-anchored molecules enables simultaneous retention of nucleic acids, proteins and lipids in diverse tissue types.

Active and passive demethylation pathways have been implicated in the genome-wide erasure of 5mC accompanying mammalian preimplantation development. Here the authors reveal a recently evolved, mammalian-specific pathway in which global hypomethylation is achieved by the coupling of active and passive demethylation.

The actin-based motor Myosin1d is needed to establish left–right asymmetry in Drosophila. Here the authors show that myosin 1d has a role in lumen formation, vacuole trafficking and left-right asymmetry establishment during zebrafish development.

The physiological role of crosstalk between mesenchymal stem cells (MSC) and macrophages is unclear. Here, Phinney et al. show that MSCs transfer mitochondria to macrophages under oxidative stress, and desensitize macrophages to mitochondria by using microvesicles to repress Toll receptor signalling.

Charged impurities are a major source of charge noise in semiconductors. Here, using pump-probe time-resolved relative transmission measurements on cuprous oxide, the authors demonstrate a strategy for mitigating charged impurities by injection and subsequent breakdown of Rydberg excitons.

Tissue engineering has opened up the possibility of studying physiological and pathophysiological processesin vitro. The foundation of this technology is a set of design principles for building three-dimensional tissues that are based on the quantitative analyses of cell and tissue behaviour.

Neutrophil elastase speeds up the progression of lung cancer by degrading insulin receptor substrate-1 and thereby phosphatidylinositol 3-kinase. This is the first description of a secreted proteinase gaining access to the inside of a cell to alter intracellular signaling (pages 161–163).

Measurements of the half-life and decay energy of the β-decay of ¹⁰⁰Sn show that Gamow–Teller transitions of this nucleus have the greatest strength found so far and are ‘superallowed’.

Deubiquitinase OTULIN targets linear (M1-linked) ubiquitin chain patches on cytosolic Salmonella Typhimurium to modulate NEMO, IKKα/IKKβ and NF-ĸB signalling and regulate secretion of pro-inflammatory cytokines and bacterial proliferation.

Rydberg excitons (condensed-matter analogues of hydrogen atoms) are shown to exist in single-crystal copper oxide with principal quantum numbers as large as n = 25 and giant wavefunctions with extensions of around two micrometres; this has implications for research in condensed-matter optics.

The paper reports a significant advance in the determination of the limit of how many neutrons a given number of protons can bind to (known as the neutron drip line), with the discovery of two new neutron-rich isotopes predicted to be drip line nuclei. Nuclei at the drip line gain stability from an unpaired proton, which narrows the shell gaps and provides the opportunity to bind many more neutrons.

While young muscle faithfully regenerates damaged myofibers, aged muscle is impaired. Here the authors show the “anti-aging” protein α-Klotho is upregulated in young muscle after damage via promoter demethylation and this regulation is lost in aging, resulting in mitochondrial damage and an impaired healing response.

Genetic and environmental factors impact on lung function, important in the diagnosis of pulmonary diseases. Here the authors use imputation of genotypes to the 1000 Genomes Project reference panel to identify novel, low frequency variants associated with lung function.

Recent work has shown that quantum mechanical effects in plasmonic nanogap structures become important as the gap distances approach the subnanometre length-scale. Here, the authors review the major findings which challenge the classical picture of these structures and discuss future directions for the field.

The DNA-damage checkpoint kinase Chk2 is a candidate tumour suppressor. Independently of DNA damage, Chk2 regulates spindle assembly and maintenance of chromosomal stability through phosphorylation of BRCA1.

Oral treatment of a purine metabolite, 8-aminoguanine (8-AG) protects the retinal morphology and function during aging by mitigating hallmarks of aging, highlighting its potential in treating age-related retinal degeneration.

The protein FAM134B is an endoplasmic reticulum (ER)-resident receptor that facilitates ER autophagy, and downregulation of this protein (mutations of which are also known to cause sensory neuropathy in humans) results in expanded ER structures and degeneration of mouse sensory neurons.

In this work, the authors transcriptionally and genetically profile 443 caudate nucleus samples, including 154 with schizophrenia, highlighting new genes associated with schizophrenia risk, including the presynaptic DRD2 isoform.
