Utilizing “Chemistry at a point”, Ni is exsolved from a perovskite lattice under deposited Pt nanoparticles. This yields even smaller Ni Pt alloy nanoparticles on a perovskite nanofiber structure, exhibiting high catalytic activity.
The uniformity of laminar processing in a cortex remains not fully understood. Here authors show that high spatial frequency stimuli elicit distinct active patterns across V1 layers, arising from multiple mechanisms involving M and P pathways.
The preparation of atom-thick lattices with Å-scale pores is desirable for achieving ion selectivity and high ion flux. Here authors present a cm-scale membrane made of atom-thick graphene film hosting zero-dimensional pores spanning only a few Å, repaired using an in situ electrochemical strategy, yielding high Li+/Mg2+ separation performance.
Roll-to-Roll (R2R) coating is a technology that potentially enhances throughput, reduces costs, and accommodates flexible substrates for fabricating various types of solar cells and modules. Here, authors discuss the R2R revolution to tackle the industrial leap for perovskite photovoltaic devices.
Controlling the selectivity of the electroreduction of CO2 to value-added products is challenging. Here, authors use sub-second operando Raman spectroscopy to analyze Cu catalyst surfaces and discover the pivotal role of co-adsorbed OH and CO in enhancing ethanol selectivity.
Damaging energy bursts in a tokamak are a major obstacle to achieving stable high-fusion performance. Here, the authors demonstrate the use of adaptive and machine-learning control to optimize the 3D magnetic field to prevent edge bursts and maximize fusion performance in two different fusion devices, DIII-D and KSTAR.
The authors find an unprecedented human-induced weakening of the Northern Hemisphere Hadley circulation in recent and coming decades, contrasting with the naturally-forced simulated strengthening over the preindustrial last millennium.
NADPH oxidase 5 (NOX5) is activated by Ca2+ signaling, catalyzing superoxide production by transferring electrons from intracellular NADPH to extracellular oxygen. Here the authors uncover the molecular basis of NOX5 activation and electron transfer.
Cities that experience compact development tend to witness more extreme rainfall over downtown than their rural surroundings, while the anomalies in extreme rainfall frequency diminish for cities with dispersed development patterns.
Precise genome editing is crucial. Here the authors demonstrate that dual inhibition of p53-mediated cell death and distinct activation of the DNA damage repair system upon DNA damage by cytosine base editor (CBE) or prime editor (PE) additively enhanced editing efficiency in hPSCs.
Carbon nanotube-based single photon emitters allow for room-temperature operation, but suffer from vanishing indistinguishability due to strong dephasing. Following a theoretical proposal, the authors tackle the problem experimentally by using a cavity to enhance the photon coherence time and the emission spectral density in the regime of incoherent good cavity-coupling.
Greenbeards encode perceptible signals, signal recognition ability, and altruism towards others displaying the signal. This study shows that activation of the greenbeard receptor gene tgrB1 increases altruism and inactivation causes kin-specific cheating in the social amoeba Dictyostelium discoideum.
Although SPI1 gene was identified as a risk factor for Alzheimer’s disease, its role in the disease remains unclear. Here, the authors show that decreasing SPI1 level exacerbates disease symptoms, whereas increasing its level ameliorates phenotypes.
Neural basis of the sensory suppression signal required to cancel peripheral vestibular input is not fully understood. Here authors show that cerebellar Purkinje cells combine sensory and motor information to predict the sensory consequences of active self-motion, thereby establishing how vestibular reafference is distinguished to cancel self-generated sensory input.
The coupling between topological electronic properties and magnetic order offers a promising route for magnetoelectric control with great potential for both applications and fundamental physics. Here, Susilo et al demonstrate the rich tunability of magnetic properties in nodal-line magnetic semiconductor Mn3Si2Te6 using pressure as control knob.
Here Pantazopoulos, Feist, García-Vidal, and Kamra explore the combination spin, phonon and photon coupling in a system of magnetic nanoparticles, and find that it leads to an emergent spin-spin interaction. This interaction is long-range and leads to an unconventional form of magnetism that can exhibit strong magnetization at temperatures very close to the critical temperature.
Inspired by fireflies, a bimodal information indication system using a photochemical afterglow material within a photonic crystal matrix is developed to display both static and changing information, such as sample type and degree of degradation.
In this study, the authors detect diverse Ehrlichia and Anaplasma bacteria in samples from Amazonian wildlife, humans and ticks that are mostly distinct from pathogens detected in the Northern Hemisphere and that might indicate emerging health hazards from tick-borne diseases in the Amazon rainforests.
Despite advances in active drug-targeting for blood-brain barrier penetration, challenges related to brain biodistribution, and drug accumulation persist. Here the authors show a molecular library design centered on cyclic tertiary amine compounds and develop a self-enhanced brain-targeted nucleic acid delivery system inspired by the neuroprotective properties of vinpocetine.
Citrus reticulata cv. Chachiensis (CRC) is used in traditional Chinese medicine to treat various ailments. Here Wen et al. provide genomic, transcriptomic and metabolomic resources for CRC and propose a possible biosynthetic pathway for bioactive components.
