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/...

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
I am very excited about a new paper from our lab by @nicole-nova.bsky.social and @kasolari.bsky.social on the persistence of CDV in wild populations. Our first foray into evolution and ecology of infectious disease. 1/n
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.
A special shout-out to my project partner and co-first author Katie Solari (@kasolari.bsky.social) for developing the approach for sequencing a new branch of CDV genomes as it posed a real challenge, especially from old samples.
A fundamental question in disease ecology remains unresolved: How can an acute, immunizing virus persist in nature? Theory says viruses like measles need huge pools of susceptible hosts. Our new preprint offers an answer. www.biorxiv.org/content/10.6...

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...

Votes for the 2026 SMBE election have been counted, and we are happy to announce that Dmitri Petrov will be the next President-Elect of SMBE, with Esther Betran and Sohini Ramachandran as the new Councilors. They will join the Council in 2027, serving 3-year terms. Congratulations! #society
Day 4 at #SMBE2026 and the keynote talk is on “Evolution in the human gut microbiome” 🦠🧬 Associate Professor Martin Sikora welcomed Associate Professor @nanditagarud.bsky.social from UCLA to the stage where she shared a very interesting talk with the @official-smbe.bsky.social community 🤩
Please welcome @vscooper.micropopbio.org as the new ASM President and Federico Sisti, Ph.D., as President-Elect. They begin their terms on July 1. ASM congratulates its new & continuing leaders and looks forward to their leadership in advancing ASM’s mission. asm.social/2Zx

Why paying peer reviewers works, according to a journal’s editor-in-chief
A biology journal that paid peer reviewers found that the approach cut the time to a first editorial decision by 85% and maintained high-quality reviews.

Sad to be missing #SMBE2026 in general but missing @nanditagarud.bsky.social plenary is particularly painful!
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!
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:

wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖
I find this unsettling: A new study in #Lancet shows that the number of faux citations in scientific articles is on the rise, and #AI is likely to blame. @aniloza.bsky.social reports. www.statnews.com/2026/05/07/l...
