New paper from the Rosin lab in collaboration with the Hawley lab 🎉 Spearheaded by postdoc Leif Benner. We use imaging and RNA-seq to better understand apyrene meiosis. Programmed meiotic errors facilitate dichotomous sperm production in the silkworm, Bombyx mori. www.pnas.org/doi/10.1073/...

I am delighted to announce that the UW Department of Biochemistry has opened searches for TWO tenure-track positions. Descriptions and links in the following two posts.

So excited to share this preprint from the Rosin lab in collaboration with the Hawley lab and @eelcotromer.bsky.social on moth spermatogenesis! We investigate the meiotic errors that occur during the formation of apyrene sperm (that have no DNA) in silkworms! www.biorxiv.org/content/10.1...

So important! Please contact your Republican senators, especially Sen. Susan Collins (R-ME), Sen. Shelley Moore Capito (R-WV), Sen. Bill Cassidy (R-LA), Sen. Katie Britt (R-AL), and Sen. Dave McCormick (R-PA). 🙏 amplify!

🚨Postdoc opportunity🚨: LepEU postdoc: comparative population genomics of European scale adaptation in butterflies 2 year, full-time PD in my group, Stockholm Univ. Applications assed on rolling basis, deadline: 23 August 2025. Planned start 1 Oct. Details: christopherwheatlab.wordpress.com

🚨 A new rule would let career scientists like NSF/NIH program officers be replaced by political appointees Already 14,000+ public comments, deadline is Friday 📣 Comments can be short. Courts consider them—and scientists with NSF/NIH experience are especially impactful Speak up! shorturl.at/WKuBj

We're hiring an entomology collections manager @nhm.org ! I have nothing to do with the search, but happy to answer questions about the museum & LA! 🧪🦋🐝🐞🐜🦗🪰🪲🪳🕷️ workforcenow.adp.com/mascsr/defau...

@jeffsekelsky.bsky.social Corbin Jones, & I give huge thanks to Frank McNally, Christoph Haag, Andy Kern, Bengt Hansson, @takashiakeralab.bsky.social & @scienceleah.bsky.social for being guests in our #Meiosis, Recombination, & Evolution of Sex class at UNC. A pic from our final session w/ students

Happy to share a new preprint from my lab! We characterize the on/off kinetics, light dosage-dependence, and more for a suite of optogenetic signaling activators in zebrafish embryos 💡 www.biorxiv.org/content/10.1...

I’m excited to share a new preprint from some of my work in the lab of @toddmacfarlan.bsky.social ! 😄 We dived into young KZFP gene clusters in different mouse strains and species to uncover mechanisms that facilitated their evolution and diversification in mice

Our (@jeffsekelsky.bsky.social Corbin Jones, & me) #Meiosis, Recombination & Evolution of Sex class @uncchapelhill.bsky.social loved talking w/ @scienceleah.bsky.social about her lab's @plos.org Genetics paper on a unique chromosome segregation mechanism in holocentric moths. doi.org/10.1371/jour...

Did you know… It’s free to publish in Journal of Cell Science – there are no submission charges, page charges or colour fees. We also plant a tree for every peer-reviewed article we publish🌳 For details, visit our website: journals.biologists.com/jcs/pages/re...

New preprint drop! Check out work from @jimmy-ly.bsky.social et al for how protein isoforms generated by alternate translation initiation create dual localization, contribute to mitochondrial function, and are mutated in disease. "Blue-tutorial" thread below. www.biorxiv.org/content/10.1...

🚨 New Paper Alert! 🚨 🐜 How did ants evolve their highly specialized queens and workers? With @adriatica.bsky.social, we reveal a key evolutionary innovation: adult control over larval feeding unlocked extreme caste dimorphism and complex societies. 🧵👇 🔗 Read in @pnas.org: doi.org/10.1073/pnas...

First mouse paper out from Elissa Lei’s lab! Congrats Dahong and all authors 🐭🐁🧬👀 “CTCF regulates global chromatin accessibility and transcription during rod photoreceptor development” www.pnas.org/doi/10.1073/...

Check out our super cool paper on aneuploidy in cells lacking Bub3. Congratulations to fantastic student Pallavi Gadgil and alum Olivia Ballew. journals.plos.org/plosgenetics...

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...

This is so cool!! Congrats @roneilllab.bsky.social and team! 🦀🧬 academic.oup.com/mbe/article/...

I just heard the news that R Scott Hawley, meiosis enthusiast and founding Dean of the Grad School of the Stowers Institute for Medical Research, passed away today. Such a loss for the science and education community. I will miss our zooms and his deep, deep wisdom

Feeling very lost today with the news of the passing of my undergrad advisor Scott Hawley. He had a huge impact on the field and on me personally. He was the first person to see me as a scientist and gave me the confidence to apply to grad school. I am so grateful to be a part of his legacy.

Sadly, our colleague and friend Scott Hawley passed away this morning. He was an irreplaceable presence and force for good in the meiosis an Drosophila communities and will be sorely missed.

I was deeply disappointed by the lack of nature/science/climate/enviro on many major end-of-year book lists—so I decided to make my own! Introducing: ✨🎁📚 The 2024 Holiday Gift Guide to Nature & Science Books ✨🎁📚 Please share: Let's make this go viral in time for Black Friday / holiday shopping!

Our #SpotlightZebrafish this week is on Dr. Abhinav Sur, a #postdoc w/ Dr. Jeff Farrell @ NICHD. His research uses single-cell transcriptomes to identify & map distinct populations across 62 stages of zebrafish embryogenesis & early larval development. (1/3)

Our paper on a centromere-enriched retroelement is out! link.springer.com/article/10.1... Congratulations to all the authors! Comments and reposts welcome and appreciated 🧬🔬
