Reliable Inference of Phylogenomic Relationship via Assembly‐Based Strategy Accommodating Raw Reads and Proteins

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Phylogenomics is a transformative approach in systematics, conservation biology, and biomedical research, enabling the inference of evolutionary relationships by leveraging hundreds to thousands of genes from genomic or transcriptomic data. However, acquiring high‐quality genomes and transcriptomes necessitates samples with intact DNA and RNA,

Multiple Twinning in Nacre and Aragonite

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.
