FWIW, I don’t think the major problem in my field, or related ones, is that people need to move faster & produce more. I read a lot of papers as part of the job, and I’m increasingly convinced we’d benefit from fewer papers and better ones, not more mediocre work produced ever more “efficiently.”

Dive deep into this new perspective piece in #GENETICS, emphasizing the limitations of classical genetics in deciphering genotype-phenotype relationships and the need for new experimental paradigms to understand context-dependent genetic effects. 🧬 🔗 buff.ly/VOi9xht

New research in #GENETICS from @msrivastava95.bsky.social, Ard Louis, and @n-martin.bsky.social focuses on fitness landscapes built from genotype–phenotype maps with a random phenotype-fitness map and makes analytic predictions about their topographical properties. 🔗 for the paper: buff.ly/VnQ796V

Dynamics of Expression Variability Contribute to Retention of Small-Scale vs. Whole-Genome Duplicates

Abstract. Genome analyses reveal that gene duplication in eukaryotes is pervasive, providing a primary source for the emergence of new genes. Nevertheless,
