Measuring selection and dominance in fitness of the insecticide-resistant Ace alleles in Drosophila melanogaster, the authors show evidence for beneficial reversal of dominance, a mechanism that can stabilize large-effect polymorphisms in nature. 🧪

I'm no Cassandra, but I've been exploring this alternative to GS if the Sentient AI Overlords pull the plug on GS. It's this and it is, currently, terrible: openalex.org

@jcbnunez.bsky.social et al. present an expanded release of the community-generated resource Drosophila Evolution over Space and Time (DEST 2.0), and showcase it by studying the species' demographic history and signatures of adaptation.

stdpopsim v0.3.0 is out! You can now mix and match your simulations of different demographic histories with published distributions of fitness effects along with gene annotations, and you can even throw in sweeps for good measure. Check out the new manuscript for more info: doi.org/10.1101/2025...
Accessible, realistic genome simulation with selection using stdpopsim
Selection is a fundamental evolutionary force that shapes patterns of genetic variation across species. However, simulations incorporating realistic selection along heterogeneous genomes in complex de...

longcallD is a new variant caller for genomic long reads. It jointly calls phased small and structural variants. Single binary, one command line for the whole process. Comparable accuracy to mainstream callers. Great work by Yan Gao. github.com/yangao07/lon...

A breathtaking coastal night scene with a sky full of stars. The calm ocean reflects the faint glow of the night, while rugged coastal rocks stand silhouetted against the horizon. In the distance, the first light of sunrise begins to emerge, casting a soft, golden hue that blends seamlessly with the deep blues and purples of the night. The atmosphere is serene and magical, capturing the quiet beauty of the transition between night and day.

A striking bird perched on a slender branch in a lush green environment. Its body is adorned with deep black plumage, contrasting sharply with a vivid red head, neck, and chest. The bird’s small, stout beak is pale and sharply defined against its dark face, while its red eyes add an intense gaze. Tiny droplets of water cling to its feathers, suggesting a recent rainfall. The blurred green foliage in the background provides a natural, vibrant setting that enhances the bird’s brilliant colors.

Watching barnacles sweep the ocean for food is so mesmerizing. They look like eyelashes opening and closing. I could watch this for hours. #barnacles #intertidal #marinelife 🦑
