Seasonal events in temperate deciduous trees, from leaf-out to leaf fall, follow a fixed annual sequence. This study shows that the timing of consecutive events is statistically associated in European trees, but that the association between fruiting and leaf coloration has weakened in some species as the interval between these phases has increased.

Covalent organic frameworks are ideal for precious metal recovery but the confinement of binding sites within inner pores often leads to restricted mass transfer and limits extraction capacities. Here, the authors report a quasi-2D topology-directed strategy to construct exposed binding sites for highly efficient gold recovery.

The authors use a genetic approach to explore redundancy within two multigene families important for Plasmodium falciparum invasion of human red blood cells, revealing that not all family members function equivalently.

Framework desymmetrization enables partial pore-space partition in acs nets, yielding part-pacs as a new pore partition mechanism. Retained open metal sites boost C₂H₂/CO₂ selectivity and productivity.

By comparing testis cell development across four mammals, this study shows that tree shrews more closely resemble primates than mice in key stages of sperm formation, supporting their use as a complementary model of human male fertility.

Two-dimensional platelets are typically formed from polymer lamellar crystals, with metastability regulated by crystallization pathways. Here, the authors report photoresponsive platelets with low metastability, which undergo controllable fragmentation on light irradiation.

Magnons in quantum Hall ferromagnets can be used as a very sensitive probe of magnetic order. Thus far, this technique has only been applied to single material systems. Here, Lee et al extend this to a heterostructure, using magnons generated in a monolayer of graphene to detect spin order in bilayer graphene.

Here, the authors introduce a hidden-layer interpretation method that maps intermediate DNN representations to probability distributions and reconstructs features to ensure faithful explanation.

In this study, the authors show that thermal stress impacts the microbiome of the sea anemone Exaiptasia diaphana differentially. Chronic and acute stress strongly affects the more sensitive line’s microbiome while the temperature tolerant line’s microbiome changed over time but not with temperature exposure.

Arable land is changing through urban encroachment, forest conversion and dryland expansion, but these shifts are often viewed separately. The study demonstrates a unifying framework for global arable land redistribution and its environmental consequences.

Here, the authors show that Darutigenol inhibits host IDO1 expression to drive A. muciniphila expansion and proline synthesis, thereby alleviating inflammation and presenting a potential strategy for IBD treatment.

Down syndrome is a complex condition which results in immune alterations, including higher risk of autoimmune diseases. Here the authors show by single cell and spatial transcriptomics that the differentiation of thymic T cell precursors is disturbed in Down syndrome, which might underpin the functional alterations.

Quantifying cell-to-module efficiency loss is critical for optimizing perovskite modules. Lan and colleagues quantify the contributions to this loss and establish fill factor preservation via cryo-controlled processing for mitigating scale-up loss. The resulting mini modules achieve a certified power conversion efficiency of 23.9%.

A domain-agnostic, training-free workflow leverages open-source large language models with explicit action sets and post-processing rules to extract laboratory procedures from unstructured text, demonstrated through zeolite synthesis.

This study finds that reasoning-enabled AI models improve diagnostic accuracy but produce more false positives and less consistent outputs but physician oversight helps retain benefits while reducing safety risks.

Here, they determine that tet(X4)-carrying Salmonella remains rare in China but is being detected more often and in a wider range of bacterial sequence types and plasmids, supporting continued surveillance.

Conway et al. utilize recent advances in cellular cryo-electron tomography to image the human mitotic spindle at nanometer resolution and reveal the mesoscale principles by which cells build complex architectures from nanoscale building blocks.

Cresols and their oxidation products contribute to secondary organic aerosol, but their role in atmospheric oxidation remains poorly quantified. The authors report rapid formation of highly oxygenated organic molecules from cresols, identifying autoxidation mechanisms that could explain substantial multi-generational contributions to toluene and cresol secondary organic aerosol.

The pathogen Listeria monocytogenes recruits host proteins to its surface within infected cells for motility and cell-to-cell spread. Here, Woida et al. adapt the split-TurboID technique to identify such proteins and show how a secreted effector co-opts a host deubiquitinase to counteract host restriction of bacterial spread.

Some plant RNA viruses use 3′ tRNA-like structures to promote translation without poly(A) tails. Here, the authors reveal how the tobacco mosaic virus tRNA-like structure directly engages host ribosomes to facilitate translation initiation.
