Lab milestone: My first (now graduated) student's first genome assembly is now publicly available! Well done, @tliesenfelt.bsky.social !! You can read the companion article below!

Shout out to the weird biology of mealybugs and the folks who study it!

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.

Wish I could be there with the rest of the crew!

Just in time for her #eseb2025 poster on Thursday, @squarehare.bsky.social 's paper on the Poecilia bifurca sex chromosomes was published today academic.oup.com/g3journal/ad...

Nate Silver: "journalists have much better bullshit detectors [than academic reviewers]" Me, an academic reviewer: that's a bold claim that sounds like the author's opinion. It needs either supporting citations or removal from the manuscript. Revise and resubmit.

Another paper on polyommatine blue butterflies just published in @genomebiolevol.bsky.social. Blues have high chromosome numbers associated with increased diversification and their karyotypes reveal strategies to maintain genomic integrity amidst profound karyotypic changes doi.org/10.1093/gbe/...

A truly great group of folks to work with!

A very cool bug! Genome coming soon from my lab!

Every reputable expert I know considers mRNA vaccine technology to be one of the most revolutionary advances in medicine in our lifetimes. Its inventors won the Nobel Prize in 2023. Shutting it down now is pointless self-harm to humanity.

This is what I've been calling the 3rd (4th?) Genomic Revolution. When I was in grad school the model was to use a few species' genomes to make generalized inferences about whole groups. Now if you want to do a genomic study of a group you just...look at the whole group, no generalizing assumption!

Excited to share our new paper in #MolEcol on sex chromosome evolution in African killifish! 🐟 A great collaboration with @alexandrsember.bsky.social . We uncovered ≥4 sex chromosome turnovers across Nothobranchius spp. using cytogenetics & genomics. 👉 onlinelibrary.wiley.com/doi/10.1111/...

Such a fun and productive trip! Be on the lookout for more on evolutionary genomics and systematics of bagworms from my lab and @dr-akito.bsky.social 's lab soon!

Good to see some of our US-based ToS members at #Evol2025! If you're at the meeting and interested or just curious about the project, say hi to @ajmongue.bsky.social @nicolevalenzuela.bsky.social @ideaspermatheca.bsky.social @emistasis.bsky.social, Mike White or Louise Heitzmann!

Getting ready for #Evol2025. If you see me say hi! I'll be doing a very preliminary talk on bagworm moth evolutionary genetics on Sunday at 11:45 as well!

Well if that's the game of the game...here's a shot of Fulgora lanternaria from a recent trip to Costa Rica.

It's finally out! This paper took quite a while but I'm so excited to share now! For anyone who studies sex chromosomes, take note: we found a rare "slower X"! (dN/dS_X < dN/dS_Autos) 👀

Re-upping this thread on PGE in mealybugs because the results are finally published in Molecular Ecology: onlinelibrary.wiley.com/doi/10.1111/...

In full sincerity, now is the moment to emphasize that undoing the changes implemented by DOGE is good for America, and increasing investment into NASA, NSF, NIH and other agencies will keep Elon from profiting off taxpayers.

How do you differentiate species when the most visible lifestage is a featureless brown rugby ball? You sequence it and place it with phylogenomics! Read all about this and the evolutionary genetics of a moth-infecting apicomplexan #parasite in our pre-print here: www.biorxiv.org/cgi/content/...

Proposed cut to NSF Biology budget is 70%. 70%. Seventy. Call your senators & reps nonstop. Give them numbers on NSF impact for state/district. tableau.external.nsf.gov/views/NSFbyN... explain this will decimate the economy if their districts, especially if it has a major research univ. 🧪

Some more mantidfly mania for #WorldBiodiversityDay These two were photographed in Costa Rica, where my lab is currently doing fieldwork (more on that soon)!

Officially (re-)annoucing the Tree of Sex! Read all about it in JEB below!

This is far from the most salient problem with the new "dire wolves," but while we're all dogpiling this story...they couldn't even name the female pup Arya or Sansa? They went with the title (not even name) of the war crimes dragon lady...absolute hacks

Excited to be part of this project! Follow the starter pack for more great repro evo researchers!

The National Science Foundation benefits communities in every state.

Roche's SBX sequencing by expansion - preprint out! www.biorxiv.org/content/10.1...

Time to update my sequencing technologies lecture!

I am thrilled to share our new review on holocentric chromosomes. It was a lot of fun to write it together with Ines Drinnenberg! Same but different: Centromere regulations in holocentric insects and plants doi.org/10.1016/j.ce...

Excited to announce another genome preprint! This one is first-authored by my first master's student, Tracy! We generated a chromosome level genome for the invasive hibiscus mealybug, a citrus crop pest. Thanks to coauthors @lmdiepenbrock.bsky.social @kkbugtime.bsky.social tinyurl.com/5n8h42r6

People need to grasp that these chaotic funding cuts aren't coming from a desire to reign in federal spending or balance budgets. They are coming from religious extremists who see science- and other forms of honest, evidence-based epistemology- as a direct threat to their political power.

If all extant cephalopods have a single origin Z chromosome, then did ammonites use that sex determination system as well? Why do all Z chromosome systems seem to date back to the Mesozoic?😮

It's finally out! The long-awaited Ross lab B chromosome paper! Check it out for more weird genetics: a selfish chromosome found in only some populations of mealybugs and in variable copy number! My old labmate Kamil has a good breakdown below!

Per an NIH source: “Discussions with colleagues have suggested that if the universities all come together and raise hell about the delays to funding caused by not holding meetings, that might move the needle. From every state. There are well-funded universities in red states that will be impacted.”

The NSF and NIH stuff is the kind of lower-salience thing where it is probably more useful to contact your representative and let them know people are pissed about this, people who vote.

Reposting because the final version finally came out and there are way more people on the site now. To you it might just be a genome note, to me it's the first fully Mongue lab paper (feat. @erincpow.bsky.social and @kkbugtime.bsky.social )! A #newPI milestone! academic.oup.com/g3journal/ar...

Recent studies have revealed unexpected Y chromosome diversity and suggest that the Y may play a big role in evolution. @vdbijl.bsky.social and I wrote this perspective for @evolletters.bsky.social with a few suggestions and requests. academic.oup.com/evlett/advan... Figs by www.jacelyndesigns.com

Hi -omics friends, I'm looking for some #sequencing recommendations: what's your favorite alternative to Novogene for doing Illumina WGS of non-model critters? (Bonus points if it's not a "Chinese company" and can get through my state's new restrictions on who we can do business with 🙃)

Wow, lots of new followers this week! To celebrate and (re)introduce myself, I want to share one of the weird reproductive systems my lab works on: Paternal Genome Elimination in mealybugs. If you have house plants, maybe you know these waxy little pests already. But do you know their genetics? 1/n

When you watch Jurassic Park but have a background in reproductive genomics... "All vertebrate embryos are inherently female" assumes XX/XY sex chromosomes, but all living dinosaurs (birds) have ZZ/ZW chromosomes which would be "inherently male" from this perspective.

Google has successfully invented the concept of an abstract, but worse. Bravo.

Would love to know who I'm missing here. Only have 42/150 filled. For insect molecular folks, and I know there are lots of us, here's a Starter Pack! Also see my Insect Genetics and Mol Bio #Feed. I think I've found a nice set of hashtags now :) #SymbioSky #Drosophiila #Insect go.bsky.app/4EuqSbc

I was looking for an #Entomology Starter Pack but I couldn't find one - so I started to build one! It's already morphing into more of a list of invertebrate aficionado/lovers. Did I miss you? Aplogies! Reply to this post and I'll remedy that! #StarterPack #Invertebrate go.bsky.app/7CaCbMC

Our paper, identifying all the cell types in the Drosophila melanogaster female reproductive tract (uterus, female-limited glands, sperm storage organs) is out today! We used single-nuclei RNA sequencing and a lot of in situ cross-validation www.pnas.org/doi/10.1073/pnas.2409850121 🪰 🧬🧪 1/n

Another mantidfly mania post: Leptomantispa pulchella from below. We're gearing up to sequence the #genome! #insects #genomics
