New UVM research published in PNAS shows that life stages evolve differently in response to changes in the environment, challenging a long-standing belief that genes guiding embryonic development don’t readily evolve in response to environmental pressures. For more: https://go.uvm.edu/xw7v0

New paper out in the Proceedings of the National Academy of Sciences. We identify regulatory variants shaping embryonic heat tolerance in Drosophila, linking lab selection to clinal and seasonal patterns in wild populations. Link: www.pnas.org/doi/10.1073/...

We’re hiring a Planetary Health Postdoc at UVM!
Join the Lauterbur, Nunez & Pespeni labs in the Department of Biology for an interdisciplinary fellowship exploring evolutionary & ecological infectious disease dynamics.
📅 Start: Flexible (May–Sept 2026)

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...

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.
