Understanding the physics of charge density waves in emerging superconductors may reveal insights into unconventional superconductivity mechanisms. Here, the authors study the temperature and magnetic-field dependence of charge-density-wave suppression in the unconventional superconductor UTe2.
Pre-satellite era observations of Antarctic glaciers are rare. A unique record of aerial expedition images of East Antarctic outlet glaciers since the 1930s reveal long-term stability and moderate thickening.
This study identifies a decadal link between sea surface temperatures off Western Australia and the western-central tropical Pacific that has emerged since 1985. Driven by external forcings and the rapid changes in the Indo-Pacific warm pool, it may impact future climate.
Here, Cottam et al. identify an L-arabinose transporter in Enterohaemorrhagic Escherichia coli and show that metabolism of this dietary sugar upregulates the type 3 secretion system, thus enhancing its fitness within the host gut.
How to facilitate the transcription of plant-specific RNA Pol V is largely unknown. Liu et al. find that a conserved RNA Pol II elongator, SPT6L, mediates DNA methylation by its association with Pol V and promoting the production of scaffold RNA.
Mimicking high-level abstraction of the brain to achieve energy advantages is a fundamental issue in neuromorphic computing. Here, the authors fabricate an asynchronous chip and demonstrate a high-accuracy neuromorphic system with power consumption of 0.7mW.
The electrostatic control of magnetic properties is central for future development of spintronic devices. Here, the authors show that the magnetic proximity effect induces an exchange shift in the band structure of graphene interfaced with CrSBr.
The application of Li-metal batteries (LMBs) is impeded by unstable solid electrolyte interphase (SEI) and uncontrollable Li dendrites growth. Here, the authors present an YF3/PMMA composite layer to achieve high-performance LMBs via the synergetic regulation of SEI mechanics and Li crystallography.
While our brain is primarily composed of lipids, their functions have largely remained unexplored. Here, authors show that specific lipids can be linked to the structural organization and functional hierarchy of the human and macaque brain.
A consistency issue with the production of porous polymer-based radiative coatings can be a significant drop in the cooling performance when dried under humid conditions. This issue is efficiently resolved by adding polymer reinforcement.
Clean air actions affect air quality greatly. Here, the authors report widespread decreases in organic aerosol (OA) in China from 2013 to 2020 with primary OA decreasing more than secondary OA. However, further reductions are challenging.
Intelligent agents can perform two types of behavior, habitual and goal-directed. The authors propose a deep learning framework using a variational Bayes approach, which computationally explains many aspects of the interaction between the two types of behaviors in sensorimotor tasks.
Polaritons – hybrid light-matter excitations – in van der Waals materials hold promise for photonics applications below the diffraction limit. Here, the authors demonstrate in-plane steering and cloaking of phonon polaritons in assembled micro-structures based on α-MoO3 films with misaligned crystallographic orientations.
The researchers showcase an exciting surface metallic Dirac-vortex cavity design with enhanced power capabilities for electrically pumped Topological Lasers in the THz spectral range.
Switchable structural and physical bistability in ferroelectric materials can be achieved as result of molecular orbital breaking. Here, the authors describe the photo-mediated bistability in organosilicon Schiff base ferroelectric crystals for the modulation of dielectric, second-harmonic generation, and ferroelectric polarization and showing good in vitro biocompatibility.
The noncovalent interaction of ammonium ion with multidentate oxygen-based host serving as a key reacting center in catalytic reactions is rare. In this work, the authors report a noncovalent interaction of ammonium ion enabled reactivity enhancement process, achieving the C–H functionalization of polyethylene glycols with acrylates.
Lichen symbiosis between chlorophyte algae and fungi is a key player in ecosystems but our understanding of its evolution and genetic regulation in algae remains limited. This study finds that lichen symbiosis evolved at least three times in algae through gene family expansion and horizontal gene transfers
The authors study tunneling junctions in rhombohedral MoS2 bilayers and correlate their performance with the local domain layout. They show that the switching behavior in sliding ferroelectrics is strongly dependent on the pre-existing domain structure.
Bacteria can use contractile injection systems, similar to viral tail structures, to deliver toxic proteins into other cells. Here, Nagakubo et al. identify a related system that modulates sporulation in multicellular Streptomyces bacteria.
