In addition to a highly collaborative lab environment we interact with a dynamic Microbiology community, DNA Replication, Recombination and Repair group and a growing list of transposon-centered lab cals.cornell.edu/microbiology cals.cornell.edu/microbiology...
The Peters lab is looking for a new team member! The role transposons play in evolution, basic mechanisms regulating transposition, and applying transposons as tools for genome modification with a special focus on guide RNA-directed transposition. cornell.wd1.myworkdayjobs.com/CornellCaree...

Great to have former lab member Mike Petassi for a seminar with our Replication, Recombination, and Repair group! Presenting some of his postdoc work in the @dnacurtain.bsky.social lab. cals.cornell.edu/microbiology...
Looking forward to this new installment of the Woods Hole Mobile DNA Meeting! Fantastic program, laid-back atmosphere, and gorgeous setting at the Marine Biological Laboratory ⛵️🪼🐋
Abstract submission closes Aug 7 but registration after that date is possible. www.eventsquid.com/event.cfm?ev...
Tn7 family transposons that include all of the guide RNA-directed transposons (CAST) are common in bacteria. We now find diverse representatives across archaea, with many in the Asgard group. Reviving an Asgard element confirmed the exciting behaviors of the family #MicroSky #TESky
Very excited about our work from @jordanthesier.bsky.social and @popomicro.bsky.social et al. We find that Tn7 family elements common in bacteria (that include all of the guide RNA-directed transposons, CAST) are also found across archaea including many in the exciting Asgard group! #MicroSky #TESky

Today is the last day to submit to be considered for a podium presentation at the EMBO transposon meeting this Fall. The organizers prioritized speaker slots sourced from submitted abstracts, we want to hear about your science!
Metal ions are universally required for life, and many of the foundational principles of metal homeostasis have emerged from studies of microbial systems. In this review, I provide a introductory overview targeted to those new to the field.

We're hiring! Do you have experience engineering yeast and using CRISPR? Jose Avalos and I are hiring a joint postdoc to work on an exciting fast-paced DARPA project with a great team at Neochromosome, Fermeate, and @joepeterslab.bsky.social

McClintock did her undergraduate and graduate studies at Cornell and we continue to be inspired by her groundbreaking work. We also have a lecture series and dormatory named in her honor at Cornell. mcclintock-lecture-series.research.cornell.edu/about-barbar...
A great day to consider a submission to #MobileDNAjournal or attending a fantastic EMBO meeting on the topic this Fall www.embl.org/about/info/c...
Happy Transposon Day! 🧬➰🧬 Commemorating Barbara McClintock's birthday (June 16th, 1902-1992). #TransposonDay2025
Linking to #microsky #transposon
Exciting work from the Guarné lab indicating how the elusive TnsE pathway of prototypic Tn7 recognizes DNA replication features using an asymmetric dimer to integrate multiple signals at DNA replication forks linking target recognition to transposase recruitment doi.org/10.1093/nar/...
First podcast recording of the day. Guest is Dr. Tory Hendry of Cornell University, chatting about interactions between fluorescent Pseudomonas and aphids!

wow, telomeric transposons in bacteria with linear chromosomes! (of course this was first figured out in flies, inc by Bob Levis, who i was happy to see few days ago at the fly meeting). 🪰

A thread from the Postdoc who led the work on bacterial Telomeric transposons. A wonderful collaboration with the Barabas lab. Officially out in the journal today!

Did you know that two jumping sequences (LINE-1 and Alu) make up nearly 30% of our genomes? Ever wonder how they jump into new genomic sites? We have some exciting discoveries to share new in @science.org on the structural mechanisms of LINE-1 retrotransposition (aka jumping 🧬➡️🧬) 🧪 #ScienceResearch

Proud to study transposons at Cornell where she did her undergraduate and graduate degrees
Very excited about this work from graduate student Laura Chacon Machado now published in Mobile DNA, "A family of Tn7-like transposons evolved to target CRISPR repeats"! #TESky
