Leah Rosin (Lee-ah Rose-in)

So excited to share this preprint from the Rosin lab (lead by postdoc @BennerLeif with help from @lingszelee) in collaboration with the Hawley lab and @EelcoTromer on moth spermatogenesis! Want to know how sperm without DNA are made on purpose? Read on! biorxiv.org/content/10.110…

New preprint 📣My postdoc, Duilio Silva, discovered the 1st toxin-antidote system in vertebrates that sabotages mouse embryogenesis! A new mechanism of genetic cheating in vertebrates!!🧬 biorxiv.org/content/10.648…

New paper from the Rosin lab in collaboration with the Hawley lab 🎉 Spearheaded by postdoc Leif Benner @BennerLeif and wonderful Hawley lab members - We use imaging and RNA-seq to better understand apyrene meiosis in silkworms. pnas.org/doi/10.1073/pn…

The @UNC_Biology Biology Department is searching for a tenure-track Assistant Professor in Plant Molecular Biology. Chapel Hill is a wonderful place and Biology is an amazing group of people. To apply, see: unc.peopleadmin.com/postings/307414

We are thrilled to announce the election of 120 members and 30 international members to the National Academy of Sciences in recognition of their distinguished and continued achievements in original research. Congratulations to our new #NASmembers and welcome to the Academy! 🎊

It's May, which means more brilliant butterflies and moths to look out for! 🌷🦋 Butterflies need wilder parks and gardens. Will you promise to let your lawn grow long for butterflies this summer? Pledge to grow not mow 👉 butterfly-conservation.org/make-your-prom… #SaveButterflies #MothsMatter

@mei_newt, Corbin Jones, & I give huge thanks to Frank McNally, Christoph Haag, @pastramimachine, @BengtHanssonLU, @TakashiAkeraLab, & @scienceLeah for being guests in our #Meiosis, Recombination & Evolution of Sex class @UNC_Biology. A pic from our last session with the students

Thrilled to share our latest preprint on satellite DNA in Bombyx mori and its close relative B. mandarina! 🧬😃 biorxiv.org/cgi/content/sh…

Our revised manuscript explains how Guo et al. concluded PRC2 is not an RNA binding protein. They retained unmappable reads, selectively removed read duplicates from the mappable fraction, and applied an arbitrary cutoff for PRC2 enrichment in RNA. biorxiv.org/content/10.110…

Cohesin is essential for maintaining structural loops but less so for regulatory loops and transcription. Is cohesin actually required for the establishment of loops and transcriptional activation?🧵bit.ly/4hXremH

New lab preprint! We did a giant genetic screen for factors that help cells to divide into more than 2 (as can occur in cancer). Our top hit is an unnamed fly gene that has a human counterpart which is targeted by an FDA-approved drug for epilepsy. biorxiv.org/content/10.110…

Exiting the microscopy room

People need to know that NIH grants are the backbone of American biology and thus of our biotech industry. I took a moment away from doing science to talk about how science gets done with @ojaldridge with @KUTNews about recent IDC rate cuts. kut.org/science/2025-0…

📢 FUNDED! I will be recruiting a computational postdoc on our favorite topic #XChromosomeInactivation role on #sexdifferences in #autoimmunity #MultipleSclerosis. If you fancy working on exceptional #singlecell #omics datasets contact me! Predoc fellow with prior experience DM

A tribute to my friend R. Scott Hawley: biologue.plos.org/2025/02/11/r-s…

My lab at Brown University is hiring a postdoctoral fellow! We develop single-molecule imaging technologies to dissect the spatial regulation of gene expression. For more information about my lab, visit weihan-li.com Please help spread the word! #RNA #imaging

We are deeply saddened by the loss of an esteemed colleague, friend, mentor & a pioneer in Drosophila & meiosis research. R. Scott Hawley was a dedicated supporter of GSA & a champion of genetics. Read an In Memoriam published in Genes to Genomes: buff.ly/3EoNQh8

The Institute mourns the loss of R. Scott Hawley, PhD. A brilliant scientist, cherished colleague, & true mentor. Scott's contributions to our understanding of genetics & passion for training the next generation of scientists will forever be remembered. bit.ly/3WPqqYG

2024 Mid-Atlantic Meiosis Mini-Symposium!! 🐭🪱🪰🧬🦠Co-organized with @scienceLeah and @FlorenciaPratto at NIH. Amazing talks from trainees and new PIs🎉 #meiosis4eva
