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.

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.

mRNA vaccines targeting SARS-CoV-2 also sensitize tumours to immune checkpoint inhibitors.

Beck et al. conducted single-cell and spatial profiling of embryonal tumors with multilayered rosettes, finding that malignant cellular hierarchies are driven by developmental programs and specific members of the chromosome 19 microRNA cluster.

An integrated experimental and deep learning pipeline reveals cell-level targeting of nanocarriers in whole bodies.

In somatic cells the mechanisms maintaining the chromosome ends are normally inactivated; however, cancer cells can re-activate these pathways to support continuous growth. Here, the authors characterize the telomeric landscapes across tumour types and identify genomic alterations associated with different telomere maintenance mechanisms.

Sepsis induces a period of immunosuppression which can be problematic in the face of subsequent infectious challenge. Here the authors show the presence of PD-L1 expressing regulatory plasma cells that can inhibit T cells in a murine model and in patients with sepsis.

Maps of protein-protein interactions (PPIs) help identify new components of pathways, complexes, and processes. In this work, state-of-the-art methods are used to identify binary Drosophila PPIs, generating broadly useful physical and data resources.

A consensus cell type atlas for the fly brain provides both an intellectual framework and open-source toolchains for brain-scale comparative connectomics.

Artificial intelligence (AI) system is known to improve dermatologists’ diagnostic accuracy for melanoma. This group applies the eye-tracking technology on dermatologists when diagnosing dermoscopic images of melanomas and reports improved balanced diagnostic accuracy when using an X(explainable) AI system comparing to the standard one.

A new study examined post-mortem kidney tissue from 63 patients with COVID-19. The results suggest that SARS-CoV-2 has kidney tropism, including the ability to replicate in kidney cells, and that kidney transduction by SARS-CoV-2 is associated with shorter survival time and increased incidence of acute kidney injury.

Conducting atom-optical experiments in space is interesting for fundamental physics and challenging due to different environment compared to ground. Here the authors report matter-wave interferometry in space using atomic BECs in a sounding rocket.

Climate change increases the frequency and intensity of drought events, affecting soil functions driven by microorganisms. Here, Metze et al. develop a method to estimate microbial growth rates in dry soils, and provide insights into the response of active microbes to drought today and in potential future climate conditions (high temperatures and CO2 levels).

Cervix and breast carcinomas are highly heterogeneous in their mechanical properties across scales. This heterogeneity provides the tumour with stability and room for cell motility.

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

JMML is an aggressive hematologic malignancy with myeloproliferative characteristics affecting young children. Here the authors report that C-type lectin-like molecule-1 (CLL-1) is upregulated in JMML and they develop CLL-1 CAR T cells showing in vitro and in vivo anti-JMML activity.

A cross-ancestry genome-wide association meta-analysis of amyotrophic lateral sclerosis (ALS) including 29,612 patients with ALS and 122,656 controls identifies 15 risk loci with distinct genetic architectures and neuron-specific biology.

A genome-wide association study including over 76,000 individuals with schizophrenia and over 243,000 control individuals identifies common variant associations at 287 genomic loci, and further fine-mapping analyses highlight the importance of genes involved in synaptic processes.

The role of androgen signalling in avian sexual development is still unclear. This study generated androgen receptor knockout chickens and find that, despite developing typical gonads, the males and females are infertile and many sexual ornaments and behaviors remain underdeveloped in both sexes.

A nanobody-based immunolabeling method, vDISCO, boosts the signal of fluorescent proteins and allows imaging of subcellular details in intact transparent mice. It uncovers neuronal projections and skull–meninges connections in whole adult mice.

Inbreeding depression has been observed in many different species, but in humans a systematic analysis has been difficult so far. Here, analysing more than 1.3 million individuals, the authors show that a genomic inbreeding coefficient (FROH) is associated with disadvantageous outcomes in 32 out of 100 traits tested.

An international team of researchers finds high potential for improving climate projections by a more comprehensive treatment of largely ignored Arctic vegetation types, underscoring the importance of Arctic energy exchange measuring stations.

Researchers created a periodically poled van der Waals semiconductor (3R-MoS₂) and achieved a macroscopic frequency conversion efficiency of 0.03% over a thickness of 3.4 μm. The quasi-phase-matched second harmonic signal surpasses the usual quadratic enhancement by 50% and broadband generation of photon pairs at telecom wavelength is demonstrated with a coincidence-to-accidental ratio of 638 ± 75.

Solid-state and solution NMR spectroscopy provide insights into the chaperone αB-crystallin's highly dynamic assembly, which is instrumental in its distinct interactions with a wide range of structurally variable clients.

Increased potential for branched-chain amino acid and lipopolysaccharide biosynthesis in the gut microbiome of insulin-resistant individuals suggests that changes in the serum metabolome induced by dysbiosis, and driven by only a handful of species, contribute to the development of diabetes.

This protocol describes surgical techniques for long-term intrathecal drug administration to rodent CNS tissue and cerebrospinal fluid collection for monitoring of drug concentration and distribution.

John Chambers, Jaspal Kooner, Pim van der Harst, Shyong Tai, Paul Elliott, Jiang He, Norihiro Kato and colleagues performed a genome-wide association study of blood pressure phenotypes in individuals of European, East Asian and South Asian ancestry. They find trait-associated SNPs at 12 loci, some of which are associated with methylation at nearby CpG sites.

A multi-ancestry genome-wide gene–smoking interaction study identifies 13 new loci associated with serum lipids.

A genome-wide association study in large cohorts of patients with different types of cancer treated with immune checkpoint inhibitors identifies genetic variants associated with immune-related adverse events.

Honey bee workers take on different tasks for the colony as they age. Here, the authors develop a method to extract a descriptor of the individuals’ social networks and show that interaction patterns predict task allocation and distinguish different developmental trajectories.

Loading of osmolytes into the phloem drives a pressure-flow transport mechanism. A maize sucrose transporter1 loss-of-function mutant has much reduced export of carbon from leaves, but increased potassium concentrations maintain phloem pressure.

A systems-level map of the Arabidopsis hormone signalling network, comprising more than 2,000 binary protein–protein interactions, reveals hundreds of interpathway contact points, many of which mediate crosstalk between different hormone pathways.

Body-scale epidermal electronic interfaces for electrophysiological recordings enable the control of a transhumeral prosthesis, long-term electroencephalography, and simultaneous electroencephalography and structural and functional MRI.
