Molecular detection of Francisella tularensis and Rickettsia spp. in ticks collected on animals in the pasture, Edirne

A molecular survey of 540 ticks collected from livestock in Edirne, Türkiye, revealed the presence of *Candidatus* Rickettsia barbariae and Rickettsia massiliae in 14.8% of pools but detected no Francisella tularensis, highlighting the region as an active ecological zone for rickettsial circulation while underscoring the need for continued surveillance of other zoonotic risks.

Pairwise tree interactions and biomass accumulation strengthen diversity-productivity effects over time

Using seven years of data from a forest biodiversity experiment and a novel Bayesian framework, this study reveals that the strengthening of diversity-productivity effects over time is driven not by shifting species interactions, but by a positive feedback loop where favorable interaction structures in diverse communities boost biomass accumulation, which in turn amplifies subsequent growth and widens the productivity gap.

Style Length in Wild Rhododendron: From Cryptic Genetic Variation to Efficient Genome Prediction Strategy

This study reveals that style length in wild *Rhododendron* is governed by a highly polygenic architecture with high heritability in hybrid populations, and demonstrates that a GWAS-informed marker prioritization strategy using a small subset of SNPs can achieve genomic prediction accuracy comparable to whole-genome approaches while significantly reducing costs for breeding long-generation woody plants.

Emergent E-I Structure in Performance-Evolved Reservoir Networks of Neuronal Population Dynamics

This paper demonstrates that the Performance-Dependent Network Evolution (PDNE) framework can autonomously evolve compact reservoir networks from minimal seeds that not only accurately predict Wilson-Cowan neuronal dynamics and generalize to unseen stimuli but also spontaneously recover the underlying excitatory-inhibitory structural organization without anatomical supervision.

Golden Morphogenesis, Aesthetic Coherence, and Geomagnetic Navigation in Rhincodon typus: A Unified Interface Model for Pelagic Migration within the Yucatán Basin

This paper proposes a unified model suggesting that the whale shark's spot patterns function as energy-dissipating aesthetic attractors derived from Fibonacci and Turing dynamics, while its Ampullae of Lorenzini act as quantum-inclinometers for geomagnetic navigation, all driven by the bioaccumulation of dietary purines and synchronized with planetary electromagnetic fields.

The Global Ocean Circuit: Coral Reefs as Piezoelectric Generators and Marine Turtles as Bio-Electrical Regulators of Ecosystem Homeostasis

This paper proposes a paradigm-shifting biophysical framework asserting that global ocean basins function as interconnected electromagnetic circuits where coral reefs generate piezoelectric energy through tidal stress and marine turtles act as essential biological regulators by maintaining the electrical conductivity of these reefs through grazing, thereby ensuring ecosystem homeostasis.

Loss of IL10 Signaling Promotes TLR9-Driven Liver Dysfunction by Allowing T Cell Receptor-Mediated T Cell Activation

This study demonstrates that in TLR9-induced hyperinflammation, the loss of IL-10 signaling exacerbates liver dysfunction by unleashing a feedforward loop of innate immune activation and T cell receptor-mediated T cell activation, potentially involving autoreactive CD8+ T cells.

A 3D image atlas chronicling cellular and structural dynamics following lung injury identifies the aberrant expansion of endothelial cells that fail to form perfused vasculature

By developing a comprehensive 3D image atlas of bleomycin-induced lung injury in mice, this study reveals that males experience more severe fibrosis and uncovers a previously uncharacterized, persistent "vascular scar" driven by the aberrant expansion of non-perfused, pro-inflammatory endothelial cells that precedes and outlasts fibrotic resolution.

Growth-year-associated variation in the bulb metabolome, bulb-associated microbiota, and root transcriptome of wild Fritillaria cirrhosa

This study reveals that growth-year-associated variations in wild *Fritillaria cirrhosa* are layer-specific rather than synchronous, with the most significant changes occurring in the fungal community composition and root transcriptome (specifically endoplasmic-reticulum protein processing) during the 3-to-4-year interval, alongside a limited set of age-associated bulb metabolites.
