- Reposted by Leah RosinI 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...
- Reposted by Leah RosinSo 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!
- As Robert Kuttner writes, the NIH will need support from Republican Senators to avoid draconian cuts to its FY2026 budget. prospect.org/politics/202...
- Reposted by Leah Rosin🚨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
- Reposted by Leah Rosin🚨 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

A pic from our final session w/ students
- Reposted by Leah RosinHappy 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...
- Reposted by Leah RosinI’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

- Reposted by Leah RosinOur (@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...
- Reposted by Leah RosinDid 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...
- Reposted by Leah RosinNew 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...
- Reposted by Leah Rosin🚨 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/...
- Reposted by Leah RosinCheck 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...
- Reposted by Leah RosinI 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/...

- Reposted by Leah RosinI 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

- Reposted by Leah RosinSadly, 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.
