Topological waves and their exotic properties are attracting intense research interest. Here, the authors report on the discovery of supertoroidal electromagnetic pulses with robust skyrmionic topology that persists upon propagation over arbitrarily long distances.
Creating highly active materials that effectively harness solar spectra is essential for photocatalysis, though challenging. Here the authors introduce a novel donor-acceptor covalent organic framework with a broad absorption range of 200 nm to 900 nm, achieving efficient artificial photocatalytic amine coupling.
Aligned collagen I is associated with the emergence of leader cells that are responsible for collective invasion. Here, the authors show that Collagen I and Yap signalling are in a feed-forward loop to drive the collective invasion of basal-like tumour cells.
Brain evolution at the cellular level is understudied. Here, the authors compare olfactory circuits from three Drosophila species, finding species-specific connectivity patterns associated with food odours and suggesting that more connectivity may be related to learning performance.
Omecamtiv mecarbil and Mavacamten are small molecules directly modulating the force produced by β-cardiac myosin. In this work, the authors describe how the modulators Omecamtiv mecarbil and Mavacamten can have opposite effects on cardiac myosin force production despite occupying the same pocket.
RH5, which is part of the trimeric RCR-complex essential for invasion, is a vaccine candidate for malaria. Here, Williams et al. show that monoclonal antibodies targeting each of the three proteins in the RCR-complex can work together to more effectively block the invasion of red blood cells by Plasmodium falciparum and design a combination vaccine candidate.
Human methyltransferase MLL4 mediates embryonic development and is dysregulated in diseases. Zhang et al. found that binding of PHD fingers of MLL4 to ASXL1/2 is required for recruitment of the deubiquitinase BAP1 to MLL4-bound active enhancers in vitro.
Implementing point spread function (PSF) engineering in high-throughput microscopy has proved challenging. Here, the authors propose a compact PSF engineering approach, which allows for enhanced depth of field and for the recovery of 3D information using single snapshots.
The development of methodologies to construct fast-moving, biodegradable polymeric nanomotors remains a challenge. Here, the authors present a light-propelled nanomotor by adorning the surface of bowl-shaped stomatocytes with gold nanoparticles achieving particle translocation in mammalian cells through the temporary disruption of the cell membrane.
Olivine iron phosphate (FePO4) is widely proposed for electrochemical lithium extraction, but particles with different physical attributes demonstrate varying Li preferences. Here, the authors characterize the electrochemical lithiation and sodiation behavior of a series of FePO4 particles with different morphology to identify critical features that enhance Li selectivity.
Extracellular vesicles have been exploited as potential therapeutic agents. Here, the authors apply a nanovial technology to select sub-populations of cells that secrete high levels of extracellular vesicles, leading to improved therapeutic efficacy when delivered in vivo.
Skyrmions, a type of topological spin texture, have been proposed for both storing and processing information. Central to this is the ability to manipulate the skyrmions, while at the same time ensuring their stability. Here, Ran, Tan, Sun and coauthors observe the bending of skyrmion strings under a thermal gradient, providing key evidence for the existence of magnon friction.
Multi-stable structures are useful in soft robotics with fewer and lightweight actuators for rapid motion. Here, authors propose a full cycle design framework for morphing structures including multi-stability, stiffness design, minimum energy-path finding, and pulling actuation.
Here, the authors perform a large GWAS for objectively quantified skin color in an East Asian population (N = 48,433), identifying potential causal genes, polygenic adaptations, and interaction between genetic variants and sun-exposure at polygenic level.
Self-incompatibility evolved to avoid self-fertilization among hermaphroditic plants, yet it remains murky how this compatibility recognition evolved. This study constructs a theoretical framework incorporating promiscuous molecular recognition into the evolutionary model of incompatibility.
Hydrogenating di-nitroaromatics with high activity and selectivity is challenging due to the process’s complexity. Here the authors present a fully exposed Pt clusters catalyst for 2,4-dinitrotoluene hydrogenation, suggesting that the synergy between multiple active sites and moderate adsorption behavior is crucial for the high catalytic activity.
