Hydrogen produced directly from neutral seawater is promising but challenging due to seawater’s complex composition. Here, the authors report a Na⁺-conducted pH-asymmetric electrolyzer that can directly split seawater into hydrogen with low electricity cost and nearly zero chloride interference.

Here, the authors report the scalable integration of electroluminescent semiconducting carbon nanotubes between nanographene electrical contacts in photonic crystal cavities, showing high coupling efficiency and dynamic electrical control of the enhanced electroluminescent light emission intensity in the telecom range.

Migrasomes are recently discovered extracellular vesicles that are produced during cellular migration. Here, the authors show that macrophage-derived migrasomes are implicated in the progression of cerebral amyloid angiopathy (CAA) through increased complement signaling using skin biopsies from CAA patients and CAA mouse models.

CD8⁺ T cells are found within peripheral tissues including the skin. Here, the authors use an interferon-gamma reporter system and viruses expressing agonistic peptides of varying affinities to investigate how T cell receptor signaling strength changes the chemotactic properties of effector CD8⁺ T cells to promote tissue-residency.

Spin-orbit torques, arising in systems with strong spin-orbit interactions, have been a major avenue of research for the potential electric control of magnetization. Recently, unconventional spin-orbit torques, with spin polarizations aligned in atypical ways have garnered interest due to the numerous advantages offered compared to their conventional counterparts. Here, Xue et al investigate ‘type-x’ spin-orbit torque switching, demonstrating both unique spin polarizations, and field-free magnetization switching in Platinum/Cobalt multilayers.

Seed banks are reservoirs of plant diversity. This study shows that nutrient addition decreases diversity of grassland seed banks, increases their similarity to aboveground communities and interacts with aboveground herbivory to affect their abundance.

UCN2 acts as a ligand for the GPCR CRHR2 and there have been conflicting reports on whether UCN2 treatment improves or worsens glucose tolerance. Here, the authors show that acute UCN2 recruits Gs and decreases glucose uptake, while chronic treatment desensitizes CRHR2 and improves glucose uptake.

Transcription termination can tune bacterial gene expression in response to diverse signals. Here, the authors use several RNA-seq approaches to map RNA ends for the transcriptome of the spirochete Borrelia burgdorferi, providing insights into various modes of transcription termination and identifying potential RNA regulators in this pathogen.

The authors report a method for producing co-factor-free fibrils from all full-length Tau isoforms. The method paves the way for reconstituting pathology resembling Tau fibrils and enables screening of Tau aggregation-modifying compounds for targeted therapies and PET tracers.

Developing perceptive and adaptable soft robots without compromising mechanical compliance is a challenge. Here, Choe et. al. developed a soft self-sensing tensile valve with a helical pinching mechanism, enabling integrated sensing and control for soft, untethered, and autonomous robotic systems.

Cohesin protein complex is a molecular machine that extrudes DNA loops. Here, authors show that bending of the molecule’s long coiled coils is driven by thermal fluctuations and engagement of ATPase domains uses ATP energy to generate strong force.

Simultaneous harvest failures across crop-producing regions are major threats to global food security. A strongly meandering jet can trigger these, however, climate and crop models underestimate effects with consequences for climate risk assessments.

Polar Solomon rings in a ferroelectric nanocrystal have been observed and electrically manipulated, which consist of two intertwined vortices and are mathematically equivalent to a \({4}_{1}^{2}\) link in topology based on knots and links theory.

The authors present a fast mid-infrared hyperspectral chemical imaging technique that uses chirped pulse upconversion of sub-cycle pulses at the image plane, with lateral resolution of 15 µm and an adjustable field of view and large spectral range. They demonstrate identification and mapping different components in a microfluidic device, plant cell, and mouse embryo.

Designing efficient multistate resistive switching devices is promising for neuromorphic computing. Here, the authors demonstrate a reversible hydrogenation in WO₃ thin films at room temperature with an electrically-biased scanning probe. The associated insulator to metal transition offers the opportunity to precisely control multistate conductivity at nanoscale.

Genetic dissection of hybrids is more difficult than inbreds as nonadditive effects are involved. Here, the authors report a pipeline for joint analysis of phenotypes, effects, and generations and demonstrate its usefulness in identification of loci associated with quality traits and improving predict accuracy in genomic selection of hybrid rice.

Keystone taxa in ecological communities are native taxa that have an especially important role in the stability of their ecosystem. This study introduces a novel method for detecting keystones in microbial communities by comparing data with and without specific species.

Noble metals have been extensively employed in a variety of hydrotreating catalyst systems. Here, the authors demonstrate that coordinating Pd with alkenyl-type ligands creates an electron-rich environment for Pd entity to weaken the interaction between Pd and unsaturated C for selective hydrogenation.

Active movement drives neural activity throughout cortex, but it is unclear how different cortical systems might use such signals. Here, the authors shed light on this by mapping how sensory and motor cortical areas encode naturalistic 3D behavior.

The role of circular RNAs (circRNAs) in modulating gene expression in cancer remains to be investigated. Here, the authors perform whole transcriptome sequencing in 104 primary neuroblastomas and reveal the involvement of MYCN in regulating circRNAs.
