Bacterial microcompartments (BMCs) are protein-bound organelles encapsulating segments of metabolic pathways. Here the authors utilize specific de novo coiled-coil protein-protein interactions to display proteins on the outer or inner surface of BMCs.
Here, the authors experimentally observed, numerically simulate, and mathematically analyze the existence of amplitude gaps for elastic vector solitons in highly deformable mechanical metamaterials consisting of rigid units and elastic hinges.
Distributing a reaction workload across laboratories can solve chemical problems more efficiently, but it is challenging to develop viable hardware and software. Here, the authors present an internet-connected network of cheap robots that can perform chemical reactions and share outcomes in real time, demonstrating a digitized approach to chemical collaboration.
One-dimensional materials such as carbon nanotubes have many applications, but not all of their properties can be described in the same way as for conventional media. Here, the authors devise a method to measure the complex optical susceptibility in a 1D nanomaterial and demonstrate it for carbon nanotubes.
Aryl sulfonamides and sultams are important pharmacophores in medicinal chemistry. Here, the authors report a practical palladium-catalyzed C–H activation assisted by amino-acid residues in the substrate leading to arylsulfonamides and bioactive peptidosulfonamide macrocycles.
The actin-based motor Myosin1d is needed to establish left–right asymmetry in Drosophila. Here the authors show that myosin 1d has a role in lumen formation, vacuole trafficking and left-right asymmetry establishment during zebrafish development.
Stromal-tumour interactions play an important role in pancreatic cancer progression. Here, they describe the development of a tumour microenvironment-responsive gold nanoparticle system incorporating all-trans retinoic acid (ATRA) and siRNA against heat shock protein 47 (HSP47), for use in pancreatic cancer treatment.
Doping carbon-based materials with nitrogen is effective for enhancing catalytic activity for oxygen reduction; however, directing nitrogen dopants to specific locations is difficult. Here the authors employ hydrogen-substituted graphdiyne as a matrix for nitrogen doping, leading to enhanced performance.
Streptococcus pneumoniae evades the action of the complement system by expressing an immuno-protective polysaccharide capsule as well as Factor H-binding proteins. Here, Pathak et al. show that these two defence mechanisms are functionally and spatially coordinated on the bacterial cell surface.
Causality inference in time series analysis based on temporal precedence principle between cause and effect fails to detect mutual causal interactions. Here, Yang et al. introduce a causal decomposition approach based on the covariation principle of cause and effect that overcomes this limitation.
Understanding the role of plasmon excitation is crucial for the realization of hot carrier devices. Here, the authors report internal quantum efficiency measurements in photoexcited gold gallium nitride Schottky diodes and elucidate the roles of surface plasmon excitation, hot carrier transport, and carrier injection in device performance.
The co-transcriptional capping of transcripts synthesized by RNA Pol II is substantially more efficient than capping of free RNA, a process that has been shown to depend on CTD phosphorylation. Here the authors demonstrate that a CTD-independent mechanism functions in parallel with CTD-dependent processes to ensure efficient capping.
The atomistic behaviour of nanocatalysts still remains largely unknown. Here, the authors reveal and explore reactions of nm-sized clusters of 14 technologically important metals in carbon nano test tubes using time-series imaging by atomically-resolved transmission electron microscopy.
The role of Polycomb Repressive Complex 1 (PRC1) is well described in development. Here, the authors investigate canonical PRC1’s regulation of transcriptional programs in breast cancer where, in addition to its repressive function, it is also recruited to oncogenic active enhancers to regulate enhancer activity and chromatin accessibility.
Exactly how hydrogen renders metals brittle is still unclear, and it remains a challenge to predict component failure due to hydrogen embrittlement. Here, the authors identify a class of grain boundaries in a nickel superalloy that deflects propagating cracks and improves alloy resistance to hydrogen.
Measuring rivers’ sediment discharge is critical to assess continental erosion and landscape dynamics, yet it remains a challenging task. Here the authors show that GRACE satellite helps quantifying river sediment discharge by measuring the increment in gravitational attraction due to sediment accumulation.
Common genetic variants associated with plasma lipids have been extensively studied for a better understanding of common diseases. Here, the authors use whole-genome sequencing of 16,324 individuals to analyze rare variant associations and to determine their monogenic and polygenic contribution to lipid traits.
Dendritic integration is important for information processing in the brain. Here, in awake mice, authors combine simultaneous dendritic recording of voltage and calcium signals, with somatic recording from Purkinje neurons, enabling characterization of dendritic spiking, action potential backpropagation, and ‘hotspots’ in spiny dendrites.
Controllable synthesis of single atom catalysts with sufficiently high metal loading remains challenging due to the tendency of agglomeration. Here the authors synthesize a series of stable atomically dispersed cobalt atoms on graphene with high Co loadings via the regeneration of active sites by atomic layer deposition.
The activity of glycosyltransferase GnT-V correlates with cancer malignancy and poor prognosis but its mechanism of action is poorly understood. Here, the authors solve crystal structures of free and substrate analog-bound GnT-V, providing insights into its catalytic mechanism and a basis for GnT-V inhibition.
