The accumulation of recombination events in selfing species may lead to a rapid fixation of both beneficial and deleterious mutations. Here, the authors resequence 781 soybean accessions, show purging of deleterious mutation during domestication, and report genome-wide associations for seed protein and oil traits.
The mechanism of nonlinear charge transport in doped conducting polymers remains elusive. Here, Wang et al. study charge transport with respect to crystalline degrees of samples and construct a model based on the tied link between Fermi liquids and Luttinger liquids, providing a universal explanation to understand nonlinear charge transport in conducting polymers.
Integrated optical computing requires programmable photonic and nonlinear elements. The authors demonstrate a phase-change metasurface mode converter, which can be programmed to control the waveguide mode contrast, and build an optical convolutional neural network to perform image processing tasks.
Ferroelectric devices with dielectric layers to modulate channel conductance have limited endurance and miniaturization. Here, the authors demonstrate a 2D ferroelectric channel transistor that integrates memory and computation capabilities, that will support the development of memory and computing fusion systems.
In Bacteroidetes, SusCD complexes mediate uptake of large nutrients across the outer membrane. SusCD structures in the apo state and in complex with β2,6 fructo-oligosaccharides reveal several substrate molecules in the binding cavity and suggest details of the pedal bin mechanism employed in glycan import.
The α-toxin LqhIII from the deathstalker scorpion inhibits fast inactivation of cardiac NaV1.5 channels. Here authors reveal the cryo-EM structure of LqhIII bound to NaV1.5 which shows that LqhIII traps the gating charges of the S4 segment in a unique intermediate-activated state and explains why LqhIII slows inactivation of NaV channels but does not open them.
Fecal microbiota transplant (FMT) is emerging as a potential treatment for graft-versus-host disease (GvHD). Here, the authors examine temporal dynamics of the bacteriome, mycobiome, and virome of a patient with GvHD who received multiple FMTs.
Hesitancy and resistance towards vaccination is a challenge for public health. Here the authors determine psychological characteristics associated with COVID-19 vaccine hesitancy or resistance attitudes in the UK and Ireland.
Catch bonds are protein–ligand interactions that exhibit enhancement of bond lifetime when subject to tensile force, which is a desirable yet elusive attribute for man-made nanoparticle interfaces. Here, the authors provide a nanoparticle design that can form catch bonds with tunable force-enhanced lifetimes under thermal excitations.
Surface oxide formation under reaction conditions may change the catalytic activity of a catalyst. Here, the authors explore the effect of atomic structure of Rh surfaces on the surface oxide formation and its influence on catalytic activity in hydrogen oxidation, revealing a high transient activity.
Genomes are partitioned into topologically associating domains (TADs). Here the authors present single-nucleus Hi-C maps in Drosophila at 10 kb resolution, demonstrating the presence of chromatin compartments in individual nuclei, and partitioning of the genome into non-hierarchical TADs at the scale of 100 kb, which resembles population TAD profiles.
The enormous application potential of THz waves demands for precise control of THz pulse generation. Here, the authors present a nonlinear metasurface that enables tunable linear polarized few cycle THz pulses.
Amazonian Dark Earth is soil that has had mysteriously high fertility since ancient times, despite the fact that surrounding soils have very low nutrients. Here the authors’ use of isotope reconstructions indicate that these soils predate human settlement and could have alluvial and burning origins.
Fast-charging of lithium-ion batteries is hindered by the uncontrollable plating of metallic Li on the graphite anode during cycling. Here, the authors demonstrate the fast chargeability and long cycle lifetimes via surface engineering of graphite with a cooperative biphasic MoOx–MoPx promoter.
Berry curvature connects to exotic electronic phases hence it provides important insights to understand quantum materials. Here, the authors report sign change of the anomalous Hall effect resulted from Berry curvature change at the interface of a topological insulator/magnetic topological insulator heterostructure.
Sul-2 is a steroid sulfatase in c.elegans. Here the authors show that, in the absence of sul-2 enzymatic activity, worm lifespan is increased, and that chemical inhibition ameliorates symptoms of neurodegenerative disorders in worms and mice.
Epitaxial strain is a promising control knob to modulate Tc to enhance superconductivity. Here, the authors show that a metallic oxide RuO2 can be turned superconducting through application of epitaxial strain in thin films grown on a (110)-oriented TiO2 substrate.
Subcellular Zn2+ compartmentalisation is essential for cell biology. Here the authors make a turn-on fluorescent Zn2+ probe that localises to multiple organelles, and correlate its location using organelle morphology derived from structured illumination microscopy.
The relationship between gene expression and morphology to classify PV interneurons is unclear. Here, the authors show transcriptional continuity of morphologically distinct mouse hippocampal PV interneurons subtypes, combining single-cell RNA sequencing and electrophysiology.
This manuscript presents ultrapure chain-like gold nanoparticle clusters with red shifted absorption and shows their potential for in vivo imaging in living rabbits. The nanoparticles demonstrate a 17-fold increase in photoacoustic microscopy signal and 176% increase in optical coherence tomography signal.
