The Potential Role of Haploblocks in the Persistence of Small, Isolated Populations of Brook Trout (Salvelinus fontinalis)

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Small brook trout populations inhabit streams of the North Mountain, Nova Scotia, where western streams have different environmental characteristics. Low‐coverage whole genome sequencing was performed on 192 brook trout, and analyses showed the presence of potential inversions among individuals of only western populations.

Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

open access: yesAdvanced Materials, Volume 37, Issue 32, August 14, 2025.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Exosomal Gene Biomarkers in Osteosarcoma: Mifepristone as a Targeted Therapeutic Revealed by Multi‐Omics Analysis

open access: yesThe FASEB Journal, Volume 39, Issue 13, 15 July 2025.
Integrated osteosarcoma and exosome gene datasets identified differentially expressed and module genes, with their intersection as candidate genes. Core genes were identified through enrichment analysis and machine learning. Core gene expression was compared between control and osteosarcoma groups.
