An experimental census of retrons, now published in Nature Biotechnology. We synthesized more than a hundred new retrons and put them through their paces, improved recombineering rates and precise editing in human cells up to 40%. nature.com/articles/s4158…

Do you think that doing science costs the same anywhere around the world? The answer is NO! and as illogical as it may sound, it costs more to do science in low-resourced countries than in high income countries. A couple of examples from my own experience as a PI in Mexico (1/🧵)

The Departments of Biological Sciences and Physics & Astronomy are recruiting faculty in the area of Molecular and Cellular Biophysics. Single-molecule and advanced microscopy approaches encouraged. Please RT, share with potential candidates, and post in your departments!

open positions listed here: shorturl.at/inrV5 Interested postdoctoral candidates can DM me on X or email: [email protected] with a current C.V.

Join us on Oct. 5! UChicago Biological Sciences, UChiPhysicalSciences, UChicago Pritzker School of Molecular Engineering, and @uchicago invite you to explore the world and your place in it with a day of 100+ free demos, interactive panels, food, and fun for all ages at the #SouthSideScienceFestival!

Time for a positive random observation: when I see the migrant families who are staying in the shelter near my place, the adults are usually paying more attention to their kids than to their phones.

Our post-doc position closes Oct 1st!

8 YEARS IN A ROW. There’s truly something for everyone in the City of Big Shoulders so it comes as no surprise here that Chicago is once again the best big city in the nation. Couldn’t be prouder. timeout.com/chicago/news/c…

We had fun with these models at the South Side Science Festival today. So many smart kids in Chicago!

Not one but TWO faculty searches in our department Cornell MBG 1️⃣ Cell & Mol Biol Weill Institute for Cell & Molecular Biology academicjobsonline.org/ajo/jobs/28336 2️⃣ Human Genetics/Genomics academicjobsonline.org/ajo/jobs/28554 Outstanding science, supportive community, beautiful environment. We have it all! Spread the word 🙏

Supercoiling toys for students in my grad class. Parts from Amazon - 2 rolls of 4mm tubing for jewelry (2mm hole) and a package of old-style bead key chains, chopped up, to provide breakable backbone bonds that swivel.

Positive observation for the day: when I went grocery shopping yesterday, an elderly man with a walker was crossing against the light, slowly. NOT A SINGLE ONE of the many cars he was holding up honked. Humans do have a good side.

🚨Hiring a Research Technician!🚨 Join our lab to study mobile DNA and its impact on biology and genome engineering! 🌟 MSc. in Molecular Biology, Biochemistry or related field required. PhD highly desired. 🌟 70% Research 30% Admin 🌍 Max Perutz Labs Vienna, Vienna BioCenter #Austria

Happy 2025!

Finally posted - our structures that explain directionality control in large serine integrases! Read all about how these amazingly clever molecular swivels are controlled: biorxiv.org/content/10.110… Great work by postdoc Heewhan Shin and many thanks to collaborator Femi Olorunniji.

The Institut Pasteur is leaving X. Due to serious issues observed since its acquisition by Elon Musk, the Institut Pasteur is suspending its activities on this platform starting today and invites its followers to join on other platforms. ➡️ linktr.ee/institutpasteur
