Molybdenum disulphide may be prepared by lithiation and exfoliation; however the process requires a long lithiation and produces low yields. Here, the authors show that metal naphthalenides may be used for the intercalation, and that the resulting products are of high quality and may be inkjet-printed.

Single-atom catalysts commonly present a random distribution of the active metal centres. Now a series of Mg-rich intermetallic compounds is introduced to enable ordered dispersed active metals. Furthermore, a cascade process is demonstrated on Mg₂₉Pd_1.3Rh_2.7, where Pd sites catalyse the semihydrogenation of phenylacetylene with subsequent hydroformylation on Rh sites.

Common photovoltaic effect is across the interface of heterojunctions. Here, the authors find that scanning a light beam can induce a persistent in-plane photoelectric voltage along silicon-water interfaces, due to the following movement of a charge packet in the vicinity of the silicon surface.

Neurogenic bladder often occurs after pelvic ganglia injury. Here, the authors designed a fiber-enhanced tissue bandage for injured pelvic ganglia that facilitates the delivery of growth factors essential for ganglia healing.

Protocols for crop genome editing would ideally be quick, efficient and specific while avoiding integration of transgenes into the genome of edited plants. Here, Lianget al. show that CRISPR/Cas9 ribonucleoproteins can be used to generate genome edited wheat plants in as little as nine weeks.

The induction of autoimmune symptoms may require both endogenous and exogenous cues. Here the authors show that a single nucleotide polymorphism in the NCF1 gene, NCF1R90H, known to be associated with systemic lupus erythematosus synergizes with mouse norovirus virus infection to promote interferon and toll-like receptor signaling to cause lupus symptoms in mice.

Ferroelectric HfO₂ is faced with an oxygen vacancy dilemma, which favors the polar phase but harm to switching behaviors. Here, the authors propose a donor-acceptor co-doping method to enhance polarization switching characteristics of the HfO₂ films.

Here, the authors determine the respiratory virome and serum cytokine profile in children diagnosed with acute respiratory tract infections (ARTI) and show that relative abundance of Propionibacterium phages as well as serum levels of TIMP-1 and PDGF-BB are increased in multiple ARTIs compared with single ARTI.

Poor electronic coupling between planes significantly reduces stacked graphene conductivity. Here, the authors measure plane-to-plane conductivity using the eutectic GaIn technique to show that insertion of self-assembled monolayers between graphene layers improves vertical conductivity by six orders of magnitude.

Large genetic cargos are precisely inserted into plant genomes.

The presence of electrically active defects on the surface of the support has been shown to be effective for N₂ activation. Here the authors discover that electron-rich polyanionic NH²⁻ defect allows for efficient ammonia synthesis via multiple reaction pathway by incorporating various affordable transition metals.

A hydrated lunar mineral, (NH₄)MgCl₃·6H₂O, is found in Chang’e-5 samples. The presence of abundant water and ammonium molecules on the Moon provides insight into the lunar degassing history and a potential resource for lunar habitation.

Northern China contains some of the world’s earliest farming societies. Here, authors use 55 ancient genomes to trace the genetic history of human migrations across northern China for the last 7500 years, and document genetic changes mirroring shifts in subsistence strategy.

This article tells the story of the earliest ceramic drainage system unearthed at the Pingliangtai site on the Central Plains of China, which represents an unprecedented social and environmental manipulation as societies faced surging environmental crises in the Late Holocene East Asian Monsoon region.

Improved guide RNAs enhance the efficiency of prime editing.

Prime editing in plants is improved fivefold through molecular engineering.

Tamlo-R32, an engineered wheat mutant allele of the Mildew resistance locus O (MLO) gene, confers resistance to powdery mildew, retains robust wheat growth, and can be transferred to other agriculturally important wheat varieties.

A base editor containing a human cytidine deaminase offers a larger editing window.

Ammonia can be synthesized electrochemically from nitric oxide, but the catalytic performance has generally not been satisfactory. Here the authors report a highly active copper–tin alloy for nitric oxide reduction to ammonia, which they test in a flow cell and a membrane electrode assembly.

2D MOFs have a variety of applications, including molecular separation and atomically thin electronics. Here authors demonstrate the preparation of monolayer and few-layer MOF single-crystals using a self-condensation-assisted CVD method.

The material-based evolution of organisms has attracted broad interdisciplinary interest, however, the fabrication of material-integrated organelles remains inadequately exploited. Here the authors engineer a bioartificial organism by integrating a semiartificial and specific virus-scavenging organelle to scavenge pathogenic waterborne viruses.

We discovered that liquid metal endowing negative mixing enthalpy with other elements could provide a stable thermodynamic condition and act as a desirable dynamic mixing reservoir, realizing the synthesis of high-entropy alloy nanoparticles.

Single DNA base pairs are edited in wheat, rice and maize using a Cas9 nickase fusion protein.

The kagome superconductor CsV₃Sb₅ exhibits a charge density wave (CDW) as well as superconductivity (SC). Here, the authors find that the CDW transition temperature decreases with decreasing sample thickness to 72 K at 27 atomic layers, but then unexpectedly increases to 120 K at 5 layers, an opposite trend to SC.

An active learning model, muTOX-AL, has been proposed for the task of molecular mutagenicity prediction. muTOX-AL is capable of rapidly enhancing its performance with a small number of labeled samples, thereby reducing experimental costs.

Edge states are excitations existing at the boundary of truncated periodic materials with specific spectral degeneracies, and their properties are enriched when materials possess a nonlinear response. Here, the authors provide experimental evidence of edge soliton formation in a nonlinear photonic graphene lattice induced in an atomic vapour cell.

Pseudo-Landau levels in strained graphene modify not only the local density of states, but also the transport through a Hall bar device.

This Perspective characterizes the major challenges to open-access water data in China. A potential data management infrastructure to improve the collection, sharing, and use of water data is outlined.

TALEN-induced mutation of all homologous copies of a gene that represses resistance to an important wheat pathogen confers a trait that has eluded plant breeders for decades.

Strong electron–electron interactions create a charge-density wave that modifies the topological state of the Weyl semimetal (TaSe₄)₂I. This implies the possibility of experimentally simulating axion electrodynamics in a solid-state material.

Rigidity, as seen in crosslinked polymers, and plastic processability are mutually exclusive properties. Here, the authors prepare a solution-processable conjugated microporous thermoset with permanent pores and demonstrate its application as a two-dimensional molecular sieving membrane for hydrogen separation.
