Researchers identified three distinct white matter hyperintensity progression patterns, validated in both patients and healthy individuals. Each pattern links to different vascular risks and outcomes, improving stroke prediction.

The authors perform a genome-wide association study of adolescent idiopathic scoliosis patients of Han Chinese descent, and identify 3 new loci for disease susceptibility.

HRGM2 is a catalogue of 155,211 high-quality metagenome-assembled genomes spanning 41 countries that allows improved genome-scale metabolic modelling and functional characterization of human gut microbes.

Polygenic scores for body mass index and obesity constructed using data from 5 million people with different ancestries were associated with distinct weight gain trajectories from early childhood to adulthood.

A genome-wide association meta-analysis study of blood lipid levels in roughly 1.6 million individuals demonstrates the gain of power attained when diverse ancestries are included to improve fine-mapping and polygenic score generation, with gains in locus discovery related to sample size.

Large-scale production of fibers from two dimensional materials opens a pathway to promising applications. Here the authors report meter-long MXene fibers with high electrical conductivity that are fabricated via continuous wet spinning and demonstrated in electrical wires.

Bright, efficient and low-drive-voltage colloidal quantum-dot LEDs that have a crosslinked-polymer quantum-dot layer, and use a sol–gel titanium oxide layer for electron transport, are reported. Integrating the QD-LEDs with a silicon thin-film transistor backplane results in a QD-LED display.

Mobilization of hematopoietic stem and progenitor cells (HSPCs) into the circulation is essential for maintaining homeostasis. Here, the authors show that Phc2 in bone marrow stromal cells represses the cell adhesion molecule Vcam1 and facilitates mobilization of HSPCs through regulation of epigenetic marks.

A gold-embedded oxide interlayer can be used to create metal–interlayer–semiconductor contacts for two-dimensional materials that exhibit low series resistance and Fermi level depinning.

Here, the authors show that higher levels of the gut bacterial clade TANB77 associate with better response to cancer immunotherapy, and further demonstrate in mice that a conserved pilin from TANB77 plays a role in enhancing immunotherapy efficacy, suggesting a potential therapeutic avenue.

Genomic analysis of 5,303 Chinese women with recurrent major depressive disorder (MDD) enables the identification and replication of two genome-wide significant loci contributing to risk of MDD on chromosome 10: one near the SIRT1 gene; the other in an intron of the LHPP gene.

The sudden deterioration of patients with novel coronavirus disease 2019 (COVID-19) into critical illness is of major concern and early assessment would be vital. Here, the authors show that a deep learning-based survival model can predict the risk of COVID-19 patients developing critical illness based on clinical characteristics at admission.

Soft biological composites have great potential in areas such as artificial tissue constructs and bio-integrated devices, but receive little attention. Here, the authors design soft biomimetic materials that can precisely reproduce the non-linear mechanics of relevant biological materials.

Age-related macular degeneration (AMD) is a major cause of blindness worldwide. Here, the authors carry out a two-stage genome-wide association study for AMD and identify three new AMD risk loci, highlighting the shared and distinct genetic basis of the disease in East Asians and Europeans.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Psoriasis is a partially heritable skin disorder, the genetic basis of which is not fully understood. Here, the authors use genome-wide association meta-analysis to discover psoriasis susceptibility loci and genes, which encode existing and potential new drug targets.

Ferrimagnetic materials offer a promising platform for fast and energy-efficient spin dynamics in next-generation spintronic devices. Here, the authors experimentally demonstrate spin–orbit-torque-driven perpendicular standing spin waves in AuPt/GdFeCo and identify the Ta capping layer as a crucial antioxidant barrier that enhances interfacial pinning and stabilizes higher-order spin-wave modes.

Iron metabolism dysregulation is associated with various diseases including cancer. Here, the authors show that one iron-triggered lncRNA LncRIM regulates cellular iron metabolism effectively by wiring up the Hippo-YAP  signaling pathway and promotes breast cancer development.

A large genome-wide association study of more than 5 million individuals reveals that 12,111 single-nucleotide polymorphisms account for nearly all the heritability of height attributable to common genetic variants.

The cellular levels of the critical coenzyme nicotinamide adenine dinucleotide (NAD)⁺ depend on its salvage pathway. Here, the authors show that the NAD⁺ salvage pathway in hypothalamic astrocytes is activated to promote obesity in high fat diet-fed mice.

Scaling effects on ferroelectric domains could impact applications for next-generation miniaturized devices. Here brownmillerite oxides are shown to demonstrate ferroelectric domains with widths down to the sub-unit-cell level.

The detection of pathogenic microorganisms is key consideration for safety across a wide range of fields. Here, the authors report on the simultaneous exfoliation and functionalisation of transition metal dichalcogenides with dextran for antibody-free detection of pathogenic Escherichia coli.

Chemical approaches to improve aqueous dispersions of conjugated polymers are limited by the feasibility of modifying the backbone or lead to poor performance. Here, Liu et al. show that ground-state electron transfer in donor:acceptor blends aids aqueous dispersion, for high conductivity and solubility.

Bioresorbable neural implants offer a promising solution to the challenges of secondary surgeries required for the removal of implanted devices. Here, the authors introduce a fully bioresorbable flexible hybrid opto-electronic system for simultaneous electrophysiological recording and optogenetic stimulation.

Capacitive coupling between tissue and flexible integrated electronics through a sealing dielectric layer facilitates long-term electrophysiology measurements, as demonstrated in ex vivo Langendorff heart models.

A previously undescribed photocatalytic approach enables the effective p-type and n-type doping of organic semiconductors at room temperature using only widely available weak dopants such as oxygen and triethylamine.

The impact of obesity on cancer remains insufficiently explored. Here the authors show that in mouse models, dysfunctional adipocytes exhibit low levels of BECN1 which induce YAP/TAZ activity to promote breast and colorectal tumor progression.
