Long-range Ret retrograde signaling drives subtype fate and functional identity in a sensory circuit

This study demonstrates that long-range retrograde signaling via the Gdnf receptor Ret stabilizes pioneer neuronal identity and drives functional diversification in the zebrafish posterior lateral line circuit by coupling target-derived cues to specific transcriptional and physiological programs.

Autism-associated Shank3B deletion drives widespread dorsal cortical hyperactivity, amplified sensory responses and accelerated propagation

Using wide-field mesoscale calcium imaging in Shank3B-deficient mice, this study reveals that disruption of the autism-risk gene SHANK3 drives a widespread dorsal cortical hyperactive state that amplifies, destabilizes, and accelerates sensory responses, providing a circuit-level explanation for sensory hyper-responsivity in autism.

Mechanochemical Pattern Formation in a Morphogen-Coupled Tissue Plate: Well-Posedness, Instability Thresholds, and Nonlinear Dynamics

This paper establishes the well-posedness of a mechanochemical plate-diffusion model coupling tissue deformation and morphogen concentration, and through spectral analysis, demonstrates that the sign of deformation-to-morphogen feedback critically determines the stability of the homogeneous state, thereby identifying the linear instability mechanisms that precede nonlinear pattern formation.

Epigenome-wide DNA methylation signatures associated with combined hormonal contraceptive use

This study identifies epigenome-wide DNA methylation signatures in peripheral blood associated with combined hormonal contraceptive use and hormonal trajectories, which correlate with synthetic hormone concentrations but not with depressive symptoms or endogenous hormone levels.

Detection of candidate PET-active species in mangrove-derived microbial consortia

This study demonstrates that a two-phase enrichment strategy using cork as a co-substrate successfully selects mangrove-derived microbial consortia capable of degrading PET, revealing specific taxa such as *Amycolatopsis*, *Nocardopsis*, *Streptomyces*, and *Ramlibacter* that harbor genes for PET depolymerization.

Single-cell transcriptomics reveals age-specific epithelial evolution and metabolic vulnerability in young breast cancer

This study utilizes single-cell transcriptomics to identify youth-specific hypermetabolic epithelial subpopulations driven by oxidative phosphorylation in young breast cancer patients, revealing a distinct age-dependent evolutionary trajectory and establishing OXPHOS inhibition as a promising targeted therapeutic strategy.

FranceGenRef: first steps towards a whole-genome reference panel grounded in French regional ancestral diversity

To address the under-representation of French ancestry in global genomic databases, this study presents the FranceGenRef panel, a whole-genome reference resource derived from 856 individuals with deep regional roots that catalogs genetic variants and their geographical distribution across metropolitan France to support future genomic medicine and research.
