We (@rileyshultz.bsky.social) tracked a recessive mutation from birth to death in honey bees. It causes ivory eyes. We collaborated across the continent to identify the mutation and it's downstream effects. Ultimately it is purified through selection on drones. We think Hamilton would be pleased!

Shultz @beeharpur.bsky.social et al. documented the trajectory of a spontaneous deleterious mutation from its origin in a single queen to its extinction, directly observing how haplodiploidy exposes recessive alleles to immediate purifying selection 🔗 doi.org/10.1093/molbev/msag156 #societyjournal

We already do this and companies who want them are happy to pay for PhD student interns. Why do precious and limited NSF funds need to be deployed for this? Most PhD student pursue industry jobs anyways - that has always been true. Use NSF funds to support basic science that industry wont support!

With academic jobs few and far between, the NSF is testing a new approach to graduate education: Giving Ph.D. students industry experience — and dollars — as part of their training. For more, see my latest for @statnews.com. www.statnews.com/2026/07/29/h...

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

Makes sense. In large swathes of Europe CDV is rare in dogs but prevalent (regionally) among red foxes. They seem to be currently a major reservoir. We are seeing recovery of many mesocarnivores across Europe, enlarging the community of hosts for CDV

Our results challenge the prevailing idea that acute, immunizing viruses need domestic animal reservoirs to persist. Instead, sufficiently connected wildlife communities may be able to sustain transmission on their own, reshaping how we think about reservoir systems for this entire class of viruses.

This one-of-a-kind study was only possible due to the precious Alaska samples provided by co-author Kimberlee Beckmen and colleagues at Alaska Department of Fish and Game. We're also grateful to co-author Ellen Brandell and the rest of the Yellowstone Wolf Project for obtaining the wolf sample.

Cannot be more excited about the lineup for the inaugural Function of Evolving Systems GRC conference I am co-organizing with the amazing Joy Bergelson. Less than a month away: August 9 - 14, 2026. Still a few spots left! And do check out the amazing list of speakers: www.grc.org/function-of-...

2026 Function of Evolving Systems Conference GRC

The 2026 Gordon Research Conference on Function of Evolving Systems will be held in Waterville Valley, New Hampshire. Apply today to reserve your spot.

How good is MiniBWA, the successor to BWA? To test it, I ran MiniBWA on sequencing from 76 different species, comparing mapping speed, rate and accuracy with BWA MEM. In short, it's really good. If you map short reads, it's well worth your time. andrewcarroll.github.io/2026/06/30/t...

The Best of Both Worlds - Assessing MiniBWA

Recently, Heng Li released MiniBWA (GitHub) alongside a paper by Heng Li and Nils Homer describing the method (paper). MiniBWA builds on the approaches in Minimap2 (also by Heng Li), but falls back on...

We are very excited to share our latest. We thought that soft sweeps would be the only type of sweep spreading across human gut microbiomes. Turns out many are hard! Reach @peterlaurin.bsky.social 's thread on why! And tomorrow at #SMBE2026 I will share this work and more!

Peter Laurin@peterlaurin.bsky.social · last mo.

Super excited to share new work with my advisor @nanditagarud.bsky.social! We re-examine the rapidity of adaptation in the human gut microbiome and begin to characterize the adaptive architecture of selective sweeps spreading across human guts. www.biorxiv.org/content/10... 1/n:

Very pleased with the response and still have spots & funding especially for students/postdocs. Sign up soon before it gets full. If you are working at or wanting to learn about the intersection of functional biology and ecology/evolution, you would get a lot of it! www.grc.org/function-of-...

Please join us in NH (perfect place to be in August!) for this inspiring conference organized by @petrovadmitri.bsky.social and Joy Bergelson. Very interdisciplinary, so I look forward to learning tons of new concepts. www.grc.org/function-of-...
