Selenium is essential for human health and mainly delivered via terrestrial foodstuffs. An advanced characterization of selenium chemical forms shows that organic matter increases its accumulation in soils but could limit its supply to plants
Microbial DNA is recognized by the cGAS-STING pathway, which leads to a type I interferon response. Here authors show that a basal flux of interferon activation could also be triggered by interference with STING trafficking from the Golgi apparatus to the lysosomes.
Multiple sequence alignments are widely used to predict protein structure, function, and phylogeny, but are uncertain with more diverged sequences. Muscle5 generates ensembles of alternative high-accurate alignments, enabling novel confidence estimates in alignments, trees, and other inferences.
Chemical energy ferroelectrics show limited control of the energy release rate. Here, the authors design spatially programmed energetic ferroelectrics with controlled energy release rates from machine learning-directed additive manufacturing and ice-templating assembly.
Here, the authors describe two opabiniid-like euarthropods with anterior proboscises from the Middle Ordovician Castle Bank Biota, Wales, UK. Phylogenetic analysis suggests that these specimens may be sister to radiodonts and deuteropods.
Ant and honeybee workers specialize on certain tasks and also on zones within the nest; but how do they avoid straying into the wrong zone? The authors conduct automated tracking experiments following thousands of individuals, revealing that workers use context-dependent rules to navigate inside the nest.
Under global warming, increased variability in El Niño sea surface temperature was projected to be detectable by about 2070. Here the authors show that the increased variability of a type of more impactful El Niño events is likely detectable by 2030.
The establishment and composition of the host microbiota is known to impact the function of the host immune response. Here the authors show that mode of delivery may impact the intestinal microbiota composition from birth and modulate the response to routine childhood vaccines.
Predicting inter-chain residue-residue distances of protein complexes is useful for constructing and evaluating quaternary structures of the protein complexes. Here, the authors develop a deep attention-based residual network method (CDPred) to predict inter-chain residue-residue distances of protein dimers.
Here, the authors investigate the maturation of Okazaki fragments with human proteins and reveal that initiator RNA removal occurs non-processively and slowly suggesting that additional pathways might exist to accelerate RNA removal in cells.
Histone chaperones and chromatin remodelers control nucleosome dynamics. Here the authors show that the Arabidopsis ASF1 chaperone primarily supplies histone variants to the HIRA complex to ensure proper epigenetic gene regulation.
The effects of detection noise on quantum metrology performances have not been rigorously investigated yet. Here, the authors fill this gap by generalising the quantum Fisher information to the case of noisy readout, and showing the consequences the imperfect measurements bring.
In most flowering plants, a single megaspore mother cell (MMC) is formed in each ovule. Here the authors show that miR160 and the auxin response factor ARF17 act to promote MMC fate via SPL/NZZ and control auxin signaling to prevent somatic cells from acquiring MMC fate.
Current vaccines against SARS-CoV-2 reduce mortality but are less effective in preventing infection. Here the authors show that intranasal vaccination with a subunit vaccine including an TLR2-stimulating adjuvant induces strong neutralising antibody and T-cell responses against SARS-CoV-2 in the lungs that protect against infection.
While it is widely acknowledged that Darwin’s descriptions of females were gender-biased, gender bias in modern sexual selection research is less recognized. This Perspective highlights that sexual selection theory and research are still male-centered and suggest strategies for alleviating biases in this field and beyond.
Magnetic skyrmions, due to their strongly nonlinearity and multiscale dynamics, are promising for implementing reservoir computing. Here, the authors experimentally demonstrate skyrmion-based spatially multiplexed reservoir computing able to perform Boolean Logic operations, using thermal and current driven dynamics of spin structures.
Stem cell models of organogenesis are a valuable tool for the study of human development, but often lack the context of tissue-tissue interaction. Here they generate human multi-lineage organoids comprising pro-epicardium, septum transversum, and liver bud, which they co-culture with heart organoids to generate a physiologically relevant model of organogenesis.
Here, the authors perform large-scale high-resolution Parkinson’s disease metagenomics analyses, revealing widespread dysbiosis characterized by overabundance of pathogens, immunogens, toxicants, and curli, reduction in neuroprotective and antiinflammatory molecules, and dysregulated neuroactive signaling.
Engineered chromodomains are promising probes to analyze histone methylation. Here the authors designed high-affinity chromodomains for enhanced genome-wide binding analysis, live-cell imaging and ultra-potent CRISPR-based gene repression.
T cells are considered important for controlling skin infections. Here, the authors report that varicella-zoster virus-specific T cells preferentially persist as tissue-resident-memory T cells in rash-involved skin after recovery from zoster.
