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.
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.
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.
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.
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.
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.
Whether and how parvalbumin-expressing neural population from Basal forebrain (BFPVNs) nuclei play a role in associative learning are not fully understood. Here authors show that BFPVNs mediate aversive associative learning via playing crucial roles in encoding outcome-related information.
A study of perennial Arabidopsis in its natural habitat revealed a seasonal switch in leaf senescence control that optimizes resource production, storage, and translocation, making the evergreen strategy adaptively relevant in seasonal environments.
The overexpression of Esyt1 presynaptic organiser in V1 spinal interneurons restores connectivity, increases motor neuron survival, and ameliorates motor phenotypes in ALS mice. So, inhibitory interneurons are a target to attenuate ALS symptoms.
In this work, the researchers realize the current-induced motion of Néel type chiral domain walls via spin-transfer-torque in the pristine van der Waals ferromagnet Fe3GeTe2 and via spin-orbit-torques in heterostructures with platinum or tungsten.
Atmospheric entry of asteroids or comets can cause significant damage to Earth. Two international bodies, the International Asteroid Warning Network (IAWN), and the Space Mission Planning Advisory Group (SMPAG) are working on dealing with potential threats.
Global climate policy has increasingly acknowledged the specific contributions of Indigenous Peoples. The outcome of COP 28, however, demonstrates that this acknowledgement has not shifted the conceptual foundations of dominant climate solutions, nor has it created space for Indigenous Peoples to effectively contribute. Drawing on our expertise as Indigenous scholars and practitioners, we offer four recommendations to shift climate policy and research away from these foundations towards reciprocal relationships with the natural world – strengthening it for future generations.
Josephson junction arrays lead quantum circuitry research, vital for quantum computing, simulation, and metrology. Here the authors show that increasing the number of links in an atomtronic Josephson junction necklace enhances the atomic circuit’s resilience to higher circulations, corresponding to higher critical currents.
Authors discover that the spin excitations of multiferroics convert the terahertz photon to the unidirectional charge current through the quantum geometrical aspect of optical process, paving the way to the terahertz photonics.
