Dielectric elastomer actuators require high driving electric fields to achieve high performances for soft robots due to their low dielectric constant and high stiffness. Here, the authors introduce polar fluorinated groups and nanodomains aggregated by long alkyl side chains into the dielectric elastomer design to overcome these issues and develop fast soft robots.
The mechanisms driving B cell differentiation into resident bone marrow plasma cells (BMPC) remain unclear. Here the authors use single cell sequencing and BMPC phenotyping to infer developmental pathways and regulation by IL-21 in germinal centres to promote maintenance of BMPC after vaccination in humans.
The peroxisomal β-oxidation enzyme ACOX1 increases in liver with obesity, but the physiological significance is unclear. Here, the authors show that liver-specific knockout of Acox1 leads to accumulation of omega-3 VLCFAs that promote metabolic health through activation of GPR120 in adipose tissue.
Tumor-resident intracellular microbiota (TRIM) could be a potential target for anticancer treatment. Here the authors report Au@Ag2Se nano-assemblies enabling bacterial killing, tumor inhibition and immune regulation in tumor microenvironment.
Here, Ge et al use cryo-electron microscopy to resolve the structure of the bacteriophage lambda tail in complex with its LamB receptor from Shigella sonnei and shed light on the conformational changes that the phage tail fiber undergoes in response to binding.
The neuronal mechanism of how the prefrontal cortex exerts top-down influence on the cingulo-striatal network during decision-making in depressive states is not fully understood. Here authors showed that negative bias in decision-making can be artificially induced via stimulating such neural network and they observed diminished top-down influences correlating with the depressive state.
The viral polymerase complex is crucial for both genome replication and transcription in non-segmented negative-strand RNA viruses. Here, the authors link varying structures of polymerase complexes with their dual functions and propose a sliding model for them to advance along the RNA templates.
The developmental fate of cells is regulated by the delicate environment created by the extracellular matrix. Here, authors investigate the impact of the full complement of conserved matrisome genes in germ cell development and gamete health in C. elegans.
Researchers mimic protein interface helices by stapling peptide side chains, or replacing hydrogen bonds with covalent ones, and synthetic helical mimics are heavily biased towards stapling. Here the authors describe bioinformatic discovery of hydrophobic triangles at helix N-termini, and rigid, bicyclic synthetic mimics of them.
This study reveals a widening range of projected North Atlantic climate states in the mid-twenty-first century. The distinct trajectories seen in sea surface temperatures are activated by global warming and may enable skillful long-lead decadal predictions.
Nanofluidic membranes have great potential in harvesting osmotic energy, but performance is hampered by insufficient permselectivity. Here, the authors solve this problem with a polyoxometalate-based nanofluidic plasmonic electron sponge membrane.
The molecular system regulating cell surface mechanics remains largely unexplored at single-cell resolution. Here, the authors report a high-throughput single-cell assay, ELASTomics, which integrates mechanical phenotyping with unbiased transcriptomics.
Estimates of palaeodiversity are biased by the incompleteness of the fossil record. Here, the authors develop DeepDive, a deep learning approach that infers richness while accounting for record heterogeneity, and test it with two empirical datasets.
Sulfide electrolytes’ incompatibility with Li metal hinders their use in all-solid-state Li metal batteries. Here, the authors propose a scalable Li-Al-Cl stratified structure, formed via strain-activated phase separation, to effectively stabilize the negative electrode/electrolyte interface.
Modelling of acidic zeolites, one of the key industrial catalysts, under realistic operating conditions is currently limited to specific cases. Here, the authors report a machine learning framework allowing for accurate high-throughput modelling.
Single cell genome sequencing approaches have identified somatic copy number variants (CNVs) in human neurons, but small sample sizes (<100 neurons) have limited the power to find recurrent patterns such as CNV hotspots in a single individual. Here, the authors develop an approach to map CNVs in 2097 neurons from a neurotypical individual, finding that >10% neurons contain at least one somatic CNV, and enabling deeper investigation of these events.
Direct radical C–H amination strategies have exhibited innovation, but challenges remain with C–H amination of electron-poor nitroarenes due to the essence of the electron-deficient nitrogen radical. Herein, the authors report a transition metal-free dehydrogenative C(sp2)-H/N-H cross-coupling between electron-poor nitroarenes and amines.
