TL;DR: Variation in male fidelity among monogamous prairie voles reflects differences in the expression, regulation, and epigenetic status of a vasopressin receptor that functions in spatial memory, and the trade-offs males face between fidelity and infidelity may promote heritable variation that is important for spatial memory and maintain variation in their levels of fidelity.

TL;DR: This study is the first to show that epigenetic modifications during early life may influence the fitness of free‐living organisms adapted to unpredictable environments.

TL;DR: The finding that the gene encoding Spike protein has been a target of both purifying and positive selection within the genome of SARS-CoV-2 is recapitulate and a test for branch-specific oversubstitution of mutations within narrow windows of the genome without reference to the genetic code is applied.

TL;DR: Physical mapping of well-studied developmental genes onto each chromosome reveals non-random spatial distribution of distinct genes and gene families, which provides insight into how certain gene families may have evolved and are transcriptionally regulated in this species.

TL;DR: Using scRNA-seq coupled with computational approaches, the authors studied transcriptional changes in cell states of sea urchin embryos during development to the larval stage using Waddington-OT, a computational approach to stitch together developmental time points.
