The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution

open access: yesNew Phytologist, EarlyView.
Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.

Dynamics of Gene and Allelic Expression During Modern Hybrid Maize Breeding

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Maize breeding has greatly improved yield through single‐cross hybrids, but the underlying gene regulatory changes remain unclear. This study analysed transcriptomes of landmark maize hybrids and their parents across developmental stages and planting densities.

Structural Elucidation and Engineering of the (S)‐scoulerine 2‐O‐Methyltransferase Enabling Regioselective Epiberberine Biosynthesis in Coptis chinensis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.

On the Naturalistic Grounds of Grounding

open access: yesRatio, EarlyView.
ABSTRACT This paper examines whether grounding can be naturalized. We adopt a tripartite framework—Ocat (scientific catalogue of existents), Otyp (ontological types), and metaphysics (natures/modal profiles)—and show that classifying as such the relata of putative grounding claims forces a dilemma.

The cardiac pacemakers: A paradigm of robustness in evolutionary biology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Functional networks in living systems are formed by many thousands of gene products. In association with those networks, several genes (four in this diagram) may be sufficient, each on its own, to ensure that the function occurs. Any one of these may be removed or blocked while leaving the others to continue functioning.

Mechanisms of Gui Zhi Fu Ling Formula in Liver Fibrosis: Metabolomics and Gut Microbiota Analysis

open access: yeseFood, Volume 7, Issue 3, June 2026.
Our study was based on the efficacy of the phenotype in an animal model and used multi‐omics to explore the mechanism of action of the compound. We found that Gui Zhi Fu Ling Formula may ameliorate hepatic fibrosis potentially associated with increased hepatic EPA and the expression of gut Pseudomonas.

Clinicopathological characteristics of patients with inoperable non‐small cell lung cancer harboring circulating NRF2 pathway mutations

open access: yesThe Journal of Pathology, Volume 269, Issue 2, Page 164-181, June 2026.
Abstract Lung cancer is the leading cause of global cancer‐related morbidity and mortality, with tobacco smoking as its strongest risk factor. Nuclear factor erythroid 2‐related factor 2 (NRF2) is a redox‐regulated transcription factor frequently dysregulated in non‐small cell lung cancer (NSCLC), leading to aggressive disease and resistance to therapy.

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Quantum electrodynamics accurately describes all known forms of modern optics and photonics regarding interactions between photons and matter. In this context, bound states in the continuum with photon confinement in momentum space are envisioned to open an exciting branch called reciprocal quantum electrodynamics. It complements the cavity counterpart
