Flexibility in Gene Coexpression at Developmental and Evolutionary Timescales Abstract. The explosion of next-generation sequencing technologies has allowed researchers to move from studying single genes to studying thousands of gene

Fischer et al. characterize differences in gene network connectivity and density, suggesting that flexibility in gene coexpression relationships could promote evolvability.

Redundant and Singular Regulatory Elements Underlie the Rapidly Evolving Pigmentation of Drosophila Abstract. A major hurdle in understanding the molecular changes responsible for metazoan diversity is the characterization of cis-regulatory elements (CREs

Brubaker et al. investigated the role of redundancy in cis-regulatory evolution in sexually dimorphic abdomen pigmentation of Drosophila melanogaster.

MBE | Influence of Gonadal and Chromosomal Sex on the Brain Transcriptome in a Mouse Species with Natural Sex Reversal

Heitzmann et al. compared brain transcriptomes of four sexual genotypes of the African pygmy mouse, showing how sex and neo-sex chromosomes impacted transcriptomes to reflect their transmission mode, evolutionary trajectories, and genomic conflicts.

Harvard University lays off fly database team The layoffs jeopardize this resource, which has served more than 4,000 labs for about three decades.

FlyBase, a Drosophila database, will lose a third of its team in early October because the Harvard grant that covered the employees’ salaries was canceled. Scientists warn that losing FlyBase could devastate fly research.

Depends on the behaviours and physiological and neurobiological mechanisms at play. For some things, they are sufficiently conserved, and we see strong genetic links. For others, they are wildly different. But when it comes to the added effect of sex, I agree it get much harder to make connections.

The "reproducibility crisis" in science constantly makes headlines. Repro efforts are often limited. What if you could assess reproducibility of an entire field?

That's what @brunolemaitre.bsky.social et al. have done. Fly immunity is highly replicable & offers lessons for #metascience
