Latest Research articles

  • Cellulose biocomposites from nanocellulose or plant fibers with polymer matrix are often not degradable and suffer from insufficient mechanical properties to replace established materials. Here, the authors demonstrate the fabrication of hydrolytically degradable polymers through in-situ polymerization of new functionally balanced oligomers within high-content lignocellulose reinforcement networks.

  • Hydrogenation is a treatment for chronic inflammation caused by high glucose levels in diabetic ulcers, However, current therapies have limitations. Here, the authors report on the creation of a visible light photocatalytic agent which depletes glucose in the wound and generates hydrogen to aid in diabetic wound healing.

  • Engineering metals often suffer from a small elastic deformation with a linear stress-strain relationship obeying Hooke’s law. Here the authors observe a large nonlinear tensile elastic deformation with a strain of >4.3% in a bulk Cu alloy that offers potential for elastic strain engineering.

  • DNA origami can be coated in a layer of silica to improve chemical and thermal stability however; it is unclear if this is a surface or interpenetrating layer. Here, the authors use in situ small-angle X-ray scattering to study silica deposition and observe internal silica formation resulting in DNA origami condensation and structure shrinkage.

  • Vertical exchange in the ocean is an important conduit connecting the surface to the deep and influences the distributions of gases, nutrients, pollutants, and other tracers. Here the authors using high-resolution observations and numerical simulations of the ocean fronts in the Northern Gulf of Mexico reveal that the interaction between the fronts and land-sea breeze creates slantwise pathways for water parcels and induces significant subduction of surface water and upwelling of bottom water.

  • Accurate estimates of carbon fluxes are important to our understanding of the carbon cycle. Here, via model-data integration, the authors disentangle anthropogenic and environmental carbon flux contributions of terrestrial woody vegetation, and find that environmental processes are weaker and more susceptible to interannual variations and extreme events in the 21st century than previously estimated.

  • Manganese has a crucial role in cGAS-STING-mediated DNA sensing and has emerged as a STING agonist. Here the authors report the design and characterization of a nanosystem incorporating manganese ions and the chemotherapeutic drug β-lapachone, inducing T-cell mediated anti-tumor immune responses in preclinical cancer models.

  • Arabidopsis thaliana potassium channel AKT1 is responsible for primary K + uptake from soil, which is functionally activated through phosphorylation and negatively regulated by an α-subunit AtKC1. Here, the authors report the structures of AKT1 at different states, revealing a 2- fold to 4-fold symmetry switch at cytoplasmic domain associated with AKT1 activity regulation.

  • IgE is a critical component of the allergic response and therapeutic targeting can alleviate symptomology. Here the authors propose the combined use of Bifidobacterium longum and a FcεRIα extracellular domain linked to a IgD/IgG4 hybrid Fc domain fusion protein called IgETRAP and show reduction of mast cell and IgE levels in models of food allergy.

  • This research quantifies the role of zero deforestation policies and potential leakages in Brazilian soybean production, the third major driver of deforestation globally. Here the authors provide the first estimates of net global avoided soy-driven deforestation from zero-deforestation import restrictions and find that such restrictions could help avoid ~40% of deforestation for soy cultivation in Brazil and ~2% of global deforestation.

  • 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.

  • Most organelles move bidirectionally on microtubule tracks, yet how this opposing movement is regulated by kinesin and dynein remains unclear. Recent work found that ARL8, a known anterograde adaptor linking the lysosome to kinesin, also links lysosomes to the retrograde motor dynein, providing key insight into bidirectional organelle movement in cells.

  • Advances in geospatial and Machine Learning techniques for large datasets of georeferenced observations have made it possible to produce model-based global maps of ecological and environmental variables. However, the implementation of existing scientific methods (especially Machine Learning models) to produce accurate global maps is often complex. Tomislav Hengl (co-founder of OpenGeoHub foundation), Johan van den Hoogen (researcher at ETH Zürich), and Devin Routh (Science IT Consultant at the University of Zürich) shared with Nature Communications their perspectives for creators and users of these maps, focusing on the key challenges in producing global environmental geospatial datasets to achieve significant impacts.

  • Chirality of magnons is an intrinsic degree of freedom that characterizes the handedness of spin precession around its equilibrium direction. This commentary summarizes recent progress on spin pumping by ferromagnetic resonance in magnetic heterostructures. In particular, the commentary highlights one fundamental issue in spin pumping: the chirality dependence of the spin current.
