Gastric cancer can vary in tumour stage and immune cell involvement. Here the authors compare gene expression in immune cell types from the blood and the tumour site from GC patients using single cell and TCR sequencing and show that IL17+CD8+ T cells have a phenotype related to that seen with exhausted cells.
With an ice-free Arctic, strong El Niño frequency increases 1/3 + . Almost half the increase by 2100 links to Arctic ice loss, not other greenhouse forcing. The Arctic’s influence on ENSO may represent a novel driver of changing climate extremes globally.
Here, the authors present Sparse Estimation of Correlations among Microbiomes (SECOM), a tool devised to characterize both linear and nonlinear relationships in microbiome data. When applied to human skin and infant gut microbiome data, SECOM is able to retrieve taxa interactions undescribed by previous methods.
Flocking, schooling, and swarming prey are thought to benefit from a confusion effect. However, here the authors show that hawks attacking swarming bats avoid confusion by steering towards a fixed point in the swarm instead of targeting any one individual.
Here the authors studied pulmonary arterial endothelial cells (PAEC) under laminar shear stress and show that this physiologic condition markedly changes chromatin accessibility at regulatory regions, when compared to cells grown in a static state. They find that KLF4 organizes chromatin by interacting with the SWI/SNF nucleosome remodeling complex to regulate vasculo-protective gene expression.
Most yeast ribosomal protein genes are duplicated but the functional significance of this duplication remains unclear. This study identifies a natural program where changing the ratio of proteins produced from duplicated genes modifies translation in response to drugs regardless of ribosome number.
Understanding how parents’ cognitive and non-cognitive skills influence their children’s educational trajectories is important for educational, family and economic policy. Here, the authors investigate parental influence on children’s education using genetic approaches.
Biological membranes exhibit the ability to self-repair and dynamically change their shape while remaining impermeable but these defining features are difficult to reconcile with mechanical robustness. Here, the authors report on the spontaneous formation of a carbon nanoskin at the oil-water interface that uniquely combines self-healing attributes with high stiffness.
Flexible electroluminescent devices are usually arduous to create. Liu et al report a 3D printing strategy to produce flexible and robust electroluminescent devices that can be integrated with soft robots for camouflage applications.
The mammalian circadian clock is composed of clock genes forming transcriptional feedback loops. Here, the authors identify a key role of the secondary feedback loop that is interlocked with the core loop to establish a perturbation-resilient clock system.
De novo development of a simplified photosynthetic reaction center protein can clarify practical engineering principles needed to build enzymes for efficient energy conversion. Here, the authors develop an artificial photosynthetic reaction center that functions without the need for sacrificial electron donors or acceptors.
Selective paraffin capture to afford high-purity olefins directly is critical but still challenging. Herein, the authors discover a distinctive ultramicroporous material featuring closely packed and linearly-extended isophthalic acid units and thus serving as a paraffin nano-trap for the efficient production of ultra-high purity olefins from paraffins.
Muconic acid is a platform chemical with wide industrial applicability. Here, the authors report efficient muconate production from glucose and xylose by engineered Pseudomonas putida strain using adaptive laboratory evolution, metabolic modeling, and rational strain engineering strategies.
Parkinson’s disease and dementia with Lewy bodies are closely related neurodegenerative disorders, although the epigenetic similarities are not well known. Here, the authors study Lewy pathology and DNA methylation in postmortem human frontal cortex, identifying differentially methylated genomic loci.
Most studies of the genetics of the metabolome have been done in individuals of European descent. Here, the authors integrate genomics and metabolomics in Black individuals, highlighting the value of whole genome sequencing in diverse populations and linking circulating metabolites to human disease.
HIV infection may affect the immune response to vaccination. Here the authors show that humoral response in persons living with HIV after the third dose of a SARS-CoV-2 vaccine is strong and higher than that achieved with the second dose, while cell-mediated immunity remains stable.
Crop rotations including legumes have been proposed as a strategy to enhance food production. Here, the authors conduct a global meta-analysis on legume-based crop rotations, showing that legume pre-crops increase 20% of yield in average across various crops and climatic regions.
The wing is a remarkable evolutionary novelty in insects. Here the authors demonstrate that the specification and regenerative capacity of the wing relies on a single wing-specific enhancer of the wingless gene in Drosophila.
Schizophrenia is highly heritable and characterized by widespread brain abnormalities. Here, the authors identify schizophrenia polygenic risk associated multimodal frontotemporal network that can serve as a transdiagnostic brain signature specific to schizophrenia.
In April 2021, Eli Lilly voluntarily asked the FDA to revoke the Emergency Use Authorization for the monoclonal antibody bamlanivimab due to reduced susceptibility in vitro to SARS-CoV-2 variants, not for safety. In this work, authors carry out a placebo-controlled phase 2 evaluation of bamlanivimab in non-hospitalized adults with COVID-19, to determine safety and efficacy.
