Developing an oscillating actuator that can directly convert solar energy into mechanical energy is highly desirable. Here, authors report a solvent-assisted light-driven oscillator by porous film that achieves excellent oscillating actuation performance and can even oscillate by carrying a load under light irradiation.
Pfs48/45, a surface protein of Plasmodium falciparum, is a promising anti-malarial vaccine candidate whose structure is not entirely resolved. Here, the authors present the structure of the full-length molecule, and characterise the binding and activity of transmission blocking antibodies.
The origin of the plateau observed in the early X-ray light curves of gamma ray bursts (GRBs) is debated. Here, the authors show that the observed plateau can be explained within the classical GRB model by considering expanding shell with initial Lorentz factor of a few tens.
Evaporation and crystal growth occur at different rates on different surfaces. Here authors show dissociative evaporation from ZnO (0001) polar surfaces is accelerated by the formation of a Zn-deficient quasi-liquid layer derived from the formation and inward diffusion of Zn vacancies that stabilize the polar surface.
Marine ecosystems are dominated by microbial communities. Inspired by the photoelectric conversion feature of the marine ecosystems, the authors design a four-species microbial community to mimic primary producer, primary degrader, and ultimate consumers, and show its ability to convert light into electricity for over one month.
Fluorescent tracers facilitate the identification and subsequent collection of tumour draining lymph node biopsies, enabling important clinical assessment. Here, the authors present a molecular gold nanocluster NIR-II fluorescent imaging probe and demonstrate its utility to visualise draining lymph nodes in breast and colon cancer mouse models.
It has been hypothesized that language depends on a capacity to produce and recognize two items (e.g., “come” + “talk”) as a single unit (e.g., “come talk”). Here, the authors show that a wild passerine also uses this capacity in vocal communication.
Multidrug-resistant Enterobacteriaceae (MRE) represent a major threat for patients’ health. Here, the authors describe how cooperation between gut commensal bacteria (Lactobacillus spp. And Clostridiales) restrict MRE colonization in mice and patients
In this work, authors demonstrate reversible vertical alignment of Ti3C2Tx MXene sheets induced by an applied in-plane electric field. Further modulation of the field can achieve programmed patterns onto various electrode substrates.
The topological properties of square-root Weyl semimetals are derived from the square of the Hamiltonian. Here, the authors propose a tight-binding model for a square-root higher-order Weyl semimetal hosting both Fermi-arc surface and hinge states.
Improving piezoelectric strain and voltage constant generally compromises piezoelectric performance and mechanical softness. Here, the authors report a bond weakening strategy for organic-inorganic hybrid piezoelectrics and mitigated these issues.
Assembling multicomponent catalysts to harness synergic effects is challenging. Now, flame spray pyrolysis permits the synthesis of ternary Pd-In2O3-ZrO2 catalysts with an optimal architecture and an enriched density of oxygen vacancies for maximal performance in CO2-based methanol synthesis.
Here, the authors show that a colonizing bacterial strain evolves in the gut by either generating ecotypes or continuously fixing beneficial mutations. They associate the first mode to metabolic mutations and the second to domestication of bacteriophages that are incorporated into the bacterial genome.
Computational properties of neuronal networks have been applied to computing systems using simplified models comprising repeated connected nodes. Here the authors create layered assemblies of genetically encoded devices that perform non-binary logic computation and signal processing using combinatorial promoters and feedback regulation.
Fusion genes have been proposed as a potential mechanism of resistance to EGFR tyrosine kinase inhibitors (TKIs) in lung cancer. Here, the authors identify gene fusions that are associated with resistance to EGFR TKIs in non-small cell lung cancers, and test how these fusions impact the response to EGFR TKIs in vitro.
Here the authors identify differences in cortical DNA methylation associated with Alzheimer’s disease pathology, and profiling nuclei from specific cell-types, find that most of these differences reflect variation occurring in non-neuronal cells.
Defects are believed to always scatter carriers. Here, the authors find that the quantum gaps in GeTe-based materials do not scatter carriers, which decouple the carriers and phonons transport leading to high thermoelectric performance.
Tong et al. describe a super pangenome assembled from long-read sequences of 545 wild and domesticated silkworms. Naturally selected (diapause, aposemantic coloration) or artificially selected (silk yield and fineness) sets of genes are delineated.
Murine models of obesity suggest that decreases in the adipose tissue regulatory T cell compartment may contribute to insulin resistance, but how this corresponds in the human clinical context is less well understood. Here the authors propose a role for interferon gamma in shrinking the adipose tissue regulatory T cell compartment seen in human obesity and assess the alterations seen during induction of dietary changes.
E. coli phage SU10 has a short non-contractile tail. Here, the authors show that after cell binding, nozzle proteins and tail fibers of SU10 change conformation to form a nozzle that enables the delivery of the phage DNA into the bacterial cytoplasm.
