Standing HA phenotypic breadth shapes H5N1 cross-host potential

This study reconstructs the evolution of hemagglutinin (HA) phenotypic traits across thousands of H5N1 viruses to demonstrate that standing phenotypic breadth, rather than simple stepwise mutations, enables the virus to rapidly diversify and adapt to new hosts like dairy cattle, offering a scalable framework for prioritizing cross-host variants.

CIRBP long isoform suppresses breast cancer metastasis via the translational activation of DCLK1-L and microtubule stabilization

This study reveals that the long isoform of the cold-inducible RNA-binding protein (CIRBP-L) suppresses breast cancer metastasis by directly binding to and enhancing the translation of DCLK1-L mRNA, which subsequently stabilizes microtubules through the inhibition of the GSK3β–HDAC6 axis.

Unstable Species Trees Reveal Fundamental Limits to Phylogenomic Inference

This study demonstrates that extreme instability in species trees across the genome of sagebrush lizards, driven by widespread introgression and geographic barriers, challenges the feasibility of inferring a single evolutionary history and supports recognizing multiple distinct species within the *Sceloporus graciosus* complex.

Multi-Objective Active Learning Overcomes Liver Tropism in LNP- Mediated mRNA Delivery to the Brain

This paper presents a reproducible, CPU-accessible machine-learning framework that employs multi-objective active learning to navigate the vast LNP formulation space, successfully identifying lipid compositions that maximize brain delivery while minimizing liver tropism, thereby overcoming a major barrier to CNS mRNA therapeutics.

Temperature-driven PSII thermal plasticity in tropical forest trees during a non-stress seasonal window

This study demonstrates that tropical forest trees exhibit modest, species-specific plasticity in photosystem II heat tolerance during a non-stress seasonal warming period, revealing that while community-level acclimation occurs, certain species already operate near functional thermal limits regardless of their leaf habit or successional status.

DACH1 expression is inversely associated with promoter methylation of CADM1, ESR1, and SLIT2 in TCGA cervical squamous carcinoma: a network-based candidate regulator discovery

This study identifies DACH1 as a novel candidate epigenetic regulator in cervical squamous cell carcinoma, demonstrating through network analysis and TCGA data that its expression is inversely associated with promoter methylation of the tumor-suppressor genes CADM1, ESR1, and SLIT2, independent of global tumor hypermethylation.

Branches of invasive maple Acer negundo are characterized by abundant photosynthetically active surface chlorenchyma

This study highlights that the invasive boxelder tree (*Acer negundo*) possesses persistent, photosynthetically active chlorenchyma on its branches that utilizes high salicylic acid levels and efficient non-photochemical quenching mechanisms to protect its photosynthetic apparatus from light stress while maintaining activity throughout the year.
