Senoversus rejuvenates cellular and organismal aging by reversing epigenetic states and restoring transcriptional homeostasis

The study demonstrates that Senoversus, a dual-factor combination of CHIR99021 and bFGF, effectively rejuvenates both cellular and organismal aging by reversing epigenetic states and restoring transcriptional homeostasis, thereby extending lifespan and improving physiological function in mice.

Low Reward and Heightened Threat Neural Activity are Both Associated with Heightened Anhedonia: A Transdiagnostic Perspective

This transdiagnostic study of 339 young adults reveals that heightened anhedonia-apprehension is uniquely associated with both reduced reward-related neural activity in the orbitofrontal cortex and ventral striatum, and unexpectedly heightened threat-related neural activity during fear extinction, underscoring the value of linking specific brain systems to empirically derived symptom dimensions.

Sexual Behavior and Reproductive Investment in the Sapotaceae-Associated Fruit Fly Anastrepha dentata (Diptera: Tephritidae) Across Contrasting Environmental Conditions

This study provides the first detailed description of the reproductive biology of *Anastrepha dentata*, revealing that this Sapotaceae-associated fruit fly exhibits exceptionally delayed sexual maturation, complex multimodal courtship behaviors including lek formation, and unusually long copulation durations across contrasting environmental conditions in central Veracruz, Mexico.

Sequentially Self-Assembled Supramolecular Nanocomplexes Enable Systemic Cas9 RNP Delivery and In Vivo Tumor Genome Editing

This study reports a sequentially self-assembled supramolecular ternary complex that enables systemic delivery of Cas9 ribonucleoproteins to tumors, achieving efficient in vivo genome editing and significant tumor growth suppression by overcoming rapid clearance and enabling selective endosomal release.

Long-term curling training reshapes region-specific patterns of prefrontal cortex resting-state activity: an expert–beginner comparison based on fNIRS

This study demonstrates that long-term curling training induces a region-specific redistribution of resting-state prefrontal cortex activity in athletes compared to novices, characterized by decreased activity in planning regions, increased activity in decision-making and control regions, and a positive correlation between training duration and inhibition-related neural activity, thereby highlighting how strategic, low-load sports reshape the brain's functional organization.

The theory of Janzen-Connell effects in corals: How dispersal and clonal growth shape pathogen-mediated coexistence

This study utilizes a lattice model to demonstrate that while long-distance coral larval dispersal and global pathogen dispersal generally promote species coexistence by mitigating Janzen-Connell effects, the specific outcome in coral communities depends on complex interactions involving clonal growth, pathogen specificity, and size-dependent demographic rates.
