Secondary metabolism and host responses during the amoebicidal interaction between Beauveria bassiana and Acanthamoeba castellanii revealed by dual RNA-seq

This study reveals that the amoebicidal interaction between *Beauveria bassiana* and *Acanthamoeba castellanii* is a context-dependent, multifactorial process driven by the fungus's environmentally regulated secondary metabolism (particularly oosporein production) and stress responses, which trigger a coordinated transcriptional reorganization of cytoskeletal and stress pathways in the amoeba.

Autistic traits in the UK Biobank

This study analyzes over 139,000 UK Biobank participants to confirm that the Autism-Spectrum Quotient (AQ) reliably replicates key findings regarding autistic diagnosis, sex differences, and STEM occupation associations, thereby validating its utility for investigating the biological influences of autistic traits in the general population.

Habitat use, Foraging Ecology and Dietary Composition of the Himalayan Serow (Capricornis sumatraensis thar) in and around Dachigam National Park, Kashmir Himalaya

This study conducted in the Kashmir Himalaya reveals that the Himalayan Serow preferentially utilizes rocky slope habitats and exhibits seasonal dietary flexibility, consuming a diverse range of vegetation including specific grasses, shrubs, and trees, thereby underscoring the need to conserve varied vegetation communities and rugged terrain to support the species' survival.

The Role of Alveolar Pneumocytes in the Lung Microenvironment of Osteosarcoma Metastases

This study demonstrates that type II alveolar pneumocytes accumulate at the periphery of osteosarcoma lung metastases and promote tumor growth through a pro-fibrotic, growth-permissive microenvironment, suggesting a novel therapeutic target for limiting metastatic progression in both human and canine patients.

A hydropathic asymmetry in the second codon position separates two otherwise matched transversions

This paper reveals that a previously overlooked hydropathic asymmetry between specific transversion pairs at the second codon position, which standard transition/transversion ratios fail to capture, is a fundamental feature of the genetic code's error minimization that significantly improves the prediction of evolutionary advantages across diverse species.

Complete reference genomes track disease notoriety, not burden: a burden–genome mismatch for priority zoonoses along China's land border

This study reveals a critical mismatch along China's land border where the availability of complete reference genomes for priority zoonoses correlates inversely with disease burden, reflecting pathogen notoriety rather than public health need and highlighting an urgent priority to sequence high-burden pathogens like brucellosis.
