Urbanisation Filters Bird Traits and Reshapes Taxonomic and Functional Diversity in Guwahati City, Assam, India

This study demonstrates that urbanisation in Guwahati, India, acts as a strong environmental filter that drastically reduces bird species richness and taxonomic diversity while increasing functional divergence, ultimately reshaping communities toward open-habitat specialists and highlighting the critical role of urban parks in sustaining avian biodiversity.

Development and Utilization of the DsRed2 Visual Reporter Gene System Driven by Soybean GmUbi Promoter

This study demonstrates that the soybean endogenous GmUbi promoter effectively drives the DsRed2 visual reporter gene to enable simple, rapid, and non-destructive screening of transgenic events in both Arabidopsis and soybean, exhibiting significantly higher activity than the CaMV 35S promoter.

Effects of Shelter Structure and Size on Artificial Shelter Selection by Juvenile Octopus maya

This study demonstrates that juvenile *Octopus maya* shelter selection is a non-random, exploratory process driven by both the specific design of artificial shelters and ontogenetic changes in behavior, with smaller individuals exhibiting greater behavioral diversity and distinct locomotor transitions compared to larger ones.

Parallel regulation of oligodendrocyte differentiation by ERK signaling pathway and DNMT3A via NKX6.2 in offspring of advanced maternal age

This study reveals that advanced maternal age impairs oligodendrocyte differentiation and myelination in offspring through the independent, parallel regulation of NKX6.2 by a biphasic ERK signaling pathway and differentiation-specific DNMT3A upregulation, identifying both as promising therapeutic targets for associated neurodevelopmental deficits.

Heterologous overexpression of OsSalT enhances drought tolerance by regulating antioxidant enzyme activity and flavonoid biosynthesis in tomato

This study demonstrates that heterologous overexpression of the rice gene OsSalT in tomato enhances drought tolerance by boosting antioxidant enzyme activity and upregulating flavonoid biosynthesis genes, thereby reducing oxidative damage and improving plant growth under water-deficit conditions.

TAOK3 marks an invasion‑competent epithelial subset in cervical cancer, and its inhibition restrains tumor growth, sensitizes to paclitaxel, and remodels the immune microenvironment

This study identifies TAOK3 as a critical marker of an invasion-competent epithelial subset in cervical cancer that drives tumor progression and immune evasion, demonstrating that its inhibition suppresses growth, sensitizes tumors to paclitaxel, and remodels the microenvironment toward anti-tumor immunity.

Inhibition of lncPostn Alleviates Oxidative Stress and Cardiac Fibrosis after Myocardial Infarction ​

This study demonstrates that inhibiting the fibroblast-enriched lncRNA lncPostn alleviates post-myocardial infarction cardiac fibrosis and oxidative stress by disrupting its interaction with CbII1, thereby destabilizing Nox4 and reducing mitochondrial ROS production, which highlights lncPostn as a promising therapeutic target for preventing and treating heart failure.
