Fast radio bursts (FRBs) are bright millisecond or shorter duration transient events. Here, the authors propose that FRB 20201124A comes from a binary system of a magnetar and a Be star with a decretion disk.
Studies of cell heterogeneity in white matter in primates have been limited to date. Here the authors describe a marmoset brain cell atlas that bridges rodent and human data, revealing strong gray-white matter glial segregation.
Technologies for monitoring electrophysiological effects of drugs in behaving animals have limitations. Here the authors report a wireless neural probe system with drug delivery capability for real-time monitoring of drug effects.
Fluorogenic detection of H2O2 in cells is established, but equivalent tools to monitor its cellular targets remain in their infancy. Here authors develop fluorogenic probes for detecting cysteine sulfenic acid, a redox modification inextricably linked to H2O2 signalling and oxidative stress.
Mutations in the spike of SARS-CoV-2 can result in the escape of the neutralising antibody response but may retain susceptibility to the cellular immune response. Here the authors show the G446S mutation in the spike protein of Omicron BA.1 is associated with altered antigen presentation and potentiates activation of specific T cell immunity.
In a ferrimagnet, there are two magnetic sublattices coupled antiferromagnetically. The dynamics of the two magnetic sublattices isn’t well understood, as the magnetic moments for each reside at different energy levels. Here, Park et al show that the magnetic moments at deeper energy levels show spin-glass like characteristics.
Responsive exocytosis in neutrophil leukocytes involves actin depolymerisation-dependent sequential release of gelatinase granules, then strongly pro-inflammatory azurophilic granules. Here authors show that the actin nucleator protein WASH facilitates the initial step of innate immune activation by gelatinase granules while inhibiting release of pro-inflammatory granules.
In animal models, maternal obesity is associated with development of neurodevelopmental disorder like phenotypes. Here the authors show in a macaque model that in obese dams, cell-free fetal DNA methylation, inflammatory cytokines, and metabolites correlated with infant brain DNA methylation, lipids, and metabolites.
Carbon neutrality initiative has stimulated the development of the sustainable methodologies for hydrogen generation and safe storage. Here the authors demonstrate that the dual-active sites of Pt single-atoms and frustrated Lewis pairs on porous nanorods of CeO2 enable the efficient additive-free H2 generation with a low CO generation through reforming of methanol and water.
The presence of SARS-CoV-2-specific antibodies alone is not an accurate determinant of immunity. In this work, the authors investigate if whole-blood based measurement of SARS-CoV-2 specific T cell responses could prognosticate the risk of possible SARS-CoV-2 infection, and recapitulate their findings in a capillary blood-based assay.
Engineered living materials (ELMs) embed living cells in a biopolymer matrix to create novel materials with tailored functions. In this work, the authors engineered bacteria to grow novel macroscopic materials that can be reshaped, functionalized, and used to filter contaminated water while also showing that the stiffness of these materials can be tuned through genetic changes.
Retinoblastoma response to treatment is difficult to predict. Here, the authors show that DNA methylation of cfDNA from aqueous humour is altered in retinoblastoma patients and can be used to identify the molecular subtypes and potentially predict treatment response.
By constructing an evolutionary trajectory of the cyclostome-gnathostome Pou5 gene family and comparing the structural and phenotypic protein variations, the authors uncover the origin of functional characteristics for the pluripotency factor Oct4.
Designing atomically uniform ensemble sites for matching targeted reaction pathway is important yet challenging in heterogeneous catalysis. Here, the authors fabricate a trimer Ni1Sb2 site featuring superior selectivity for acetylene semi-hydrogenation via a mechanism-driven design strategy.
A new study assesses the feasibility of a fully renewable based power system by 2050 across India, finding this option to be cost competitive with the status quo and with zero GHG emissions.
Genome-wide profiling of chromatin accessibility by DNase-seq or ATAC-seq has been widely used to identify regulatory DNA elements and transcription factor binding sites. Here the authors develop a computational model, SELMA, to estimate and correct enzymatic cleavage biases in chromatin accessibility profiling data.
Understanding the how silicon deforms under pressure is important for several fields, including planetary science and materials design. Laser-driven shock compression experiments now confirm that shear stress generated during compression is released via a high-pressure phase transition.
The European X-ray FreeElectron Laser Facility generates ultrashort hard X-ray pulses with megahertz repetition rate. Here, the authors probe the dynamics of dense antibody protein (Ig-PEG) solutions using megahertz X-ray photon correlation spectroscopy at the European XFEL.
Assembly artificial pathway in design connecting media can increase biosynthetic efficiency, but the choice of connecting media is limited. Here, the authors develop a new protein assembly strategy using a pool of docking peptides from polyketide synthase and show its application in astaxanthin biosynthesis in E. coli.
Over the last two and a half years, Nature Communications has received thousands of submissions related to the COVID-19 pandemic and accepted hundreds for publication. To showcase the breadth and quality of this work, we are now launching a COVID-19 Collection, and here we reflect on our editorial processes during this period.
