High-resolution comparative single-cell transcriptomics of doublesex-expressing neurons reveals evolutionary conservation and diversity of sexual circuits in Drosophila

Justin T. Walsh, Ian P. Junker, Yu‐Chieh Chen…·Yun Ding

This study uses single-cell transcriptomics to compare doublesex-expressing neurons across Drosophila species, revealing conserved cell types and species-specific gene expression differences in sexual circuits.

Ant nurse workers exhibit behavioral and transcriptomic signatures of specialization on larval stage

Justin T. Walsh, Michael R. Warner, Adrian Kase…·Timothy A. Linksvayer

The paper shows that ant nurse workers specialize in caring for larvae of specific stages, with molecular evidence of gene expression differences related to larval age.
