Plant leaf structure is classified as either simple or compound. A simple leaf is a single leaf, whereas a compound leaf is composed of several leaflets emerging from a single compound leaf primordia. Liangliang He, Yu Liu and colleagues have identified a regulator of compound leaf formation in Medicago truncatula, leading to the discovery of an undefined class of eudicot-specific BEL1-like homeodomain proteins and a molecular framework controlling trifoliate leaf patterning.

The search for lunar polycyclic aromatics is challenging. Here abundance, aromatic structures and carbon isotope composition of polycyclic aromatics in Chang’E 5 lunar soils are reported, shedding light on the fate of polycyclic aromatics and accretion of organic carbon on the Moon.

De novosynthesis is the primary way to tune the emission colour of lanthanide-doped upconversion nanocrystals. Here, the authors introduce post-synthetic cation exchange as a strategy to access multiple colours of luminescent nanocrystals, preserving the size and morphology of the original template.

The authors report a Yin-Yang balance between α-Synuclein and β-Synuclein via regulating phase separation in physiological states and Parkinson’s disease. AI-designed peptides mitigate the symptoms and prolong the lifespan of C. elegans PD models.

The FarmGTEx Project aims to understand genetic control of gene activity under diverse biological and environmental contexts in domestic animals, providing a foundation for improving animal precision breeding, adaptation and human health.

Generative AI holds promise for creating novel compounds. Here, authors introduce TamGen, a GPT-like model designed to generate molecules tailored to specific target proteins. TamGen identified 14 potent compounds against the Tuberculosis ClpP protease, showing its potential for drug discovery.

KIM1 is dramatically upregulated in acute kidney injury (AKI) and but how KIM1 affects AKI remains unknown. Here, the authors report that renal specific Kim1 knockout relieves AKI, unveil a YY1-KIM1-DR5 axis in the progression of AKI, and suggest potential therapeutic strategies against AKI.

Three key challenges to reducing uncertainty in geoenergy development—lack of large-scale time-lapse monitoring, the absence of microbial tracer selection, and the oversight of front propagation velocity—can be addressed using DNA-sequencing of microbes in subsurface fluids.

There are distinct hypermethylation patterns in gene promoters in hepatocellular carcinomas (HCCs). Here, the authors show that the enhancer of C/EBPβ is recurrently hypomethylated in human HCCs, recapitulating this in a transgenic murine model and linking aberrant enhancer hypomethylation to hepatocarcinogenesis.

The application of stimulated-emission depletion (STED) microscopy for deep-tissue imaging in the near-infrared optical window is challenged by high cellular autofluorescence. Here the authors present a lanthanide nanoprobe whose electronic configuration enables long-term STED imaging with reduced background noise.

Indicine cattle make up half of all cattle populations worldwide. Using a large genomic dataset, this study finds historic migrations and extensive introgression with domestic and wild bovine species has facilitated this species physiological adaptation to extreme environments.

Bottleneck effects of plant barriers on pathogenic invasions remain unclear. Using a random barcoding approach, this study investigates how plant root permeability limits the invasion and population bottlenecks of a phytopathogenic Ralstonia.

Photosystems (PS) I and II undergo state transitions to optimize photosynthesis and photoprotection. Here the authors report a cryo-electron microscopy structure of the state 2 PSI-LHCI-LHCII supercomplex from C. reinhardtii revealing subunit organization and possible pathways of energy transfer.

Cryo-electron microscopy structures of three adhesion G protein-coupled receptors (aGPCRs) complexes provide insight into the tethered activation mechanism of aGPCRs and show the potential for rational design of agonists.

Pinnate compound leaves sequentially produce their leaflets along the longitudinal axes. The study identifies the MPL1 gene as a key regulator in orchestrating an acropetal pattern of leaflet formation during the chickpea pinnate leaf development.

Exploring the diversity of the wild progenitor of the wheat D subgenome allows for rapid trait discovery.

Gibberellins are a major class of phytohormones that regulate plant growth and development. Here the authors show that the Arabidopsis GAS2 protein catalyses production of DHGA₁₂, an atypical bioactive GA, and show that GAS2 regulates ABA sensitivity during seed germination and early development.

The direct use of ammonia for asymmetric synthesis is highly sought after. Now, an efficient enantioselective carbene insertion into the N–H bond of ammonia has been developed, producing diverse valuable chiral α-amino acids.

Here, the authors identify and characterize two mouse-derived monoclonal antibodies against SARS-CoV-2 spike protein that target different epitopes in RBD and block the interaction S/ACE2 and show that a formulated humanized version cocktail exhibits prophylaxis and therapeutic antiviral effects in an hACE2-adenovector expressed mouse model.

Global warming-driven deglaciation in high-mountain Asia raises the likelihood of natural dam failure and associated glacial lake outburst flood risk. This is estimated for lake development under present-day and future warming scenarios, highlighting emerging hotspots and transboundary impacts.

Polyacetylene is an ideal system to probe to gain a better understanding of the nature of charge transport in conducting polymers. Now, individual atomically precise polyacetylene chains have been synthesized on a copper surface and characterized using a range of techniques, revealing a doping-induced semiconductor-to-metal transition.

Dielectrics with high capacitive energy storage density are essential for modern electrical devices and pulsed power systems. Here, the authors realised superior energy storage performance in lead-free bismuth ferrite-based relaxor ferroelectric films through ___domain engineering.

Luminescent materials that are capable of binary temporal coding are desirable for multilevel anti-counterfeiting. Here, the authors engineer nanoparticles that produce binary color codes on different timescales by combining the long-lived luminescence of Mn²⁺ with the relatively short-lived emission of lanthanides.

Obesity increases the risk of hepatocellular carcinoma (HCC) especially in men. Here the authors find a potential mechanistic explanation by showing that, in mice, obesity-induced STAT3 cooperates with the androgen receptor to activate the mTORC pathway through up regulation of CCRK, resulting in hepatic steatosis worsening and HCC development via metabolic and immune reprogramming.

The crystal engineering of metal–organic frameworks has led to the construction of complex structures, but has yet to reach the same level of sophistication as organic synthesis. Here, Zhou and colleagues use retrosynthetic chemistry to design and produce complex multi-component frameworks.

All-inorganic perovskite nanocrystals containing caesium and lead provide low-cost, flexible and solution-processable scintillators that are highly sensitive to X-ray irradiation and emit radioluminescence that is colour-tunable across the visible spectrum.

The authors propose a new role for ADAR1, an RNA editing enzyme, in nonalcoholic fatty liver disease (NAFLD). Overexpression of ADAR1 ameliorates high-fat diet-induced liver injury and significantly abolishes NLRP3 inflammasome activation in THP-1 cells. Inhibition of ADAR1 expression causes a dramatic enhancement in NLRP3 inflammasome activation. Therefore, ADAR1 is a potential NAFLD suppressor through regulation of NLRP3 inflammasomes.
