Happy to share the last pre-print from my lab. Just in time for Evan’s thesis defense www.biorxiv.org/content/10.1...

New ERC funded computational postdoc position in my lab! We are looking for someone who will study the genomics of bacterial evolution using samples from experimental evolution and clinical trials. Lots of opportunities for interesting and fun collaboration! my.corehr.com/pls/uoxrecru...

🚨New paper out! #MicroSky Studying obligate predators like Bdellovibrio bacteriovorus is tricky—essential genes for predation are also essential for survival. We expanded its genetic toolbox: 🧬promoters to fine-tune expression 🧬IPTG-inducible system 🧬CRISPRi for rapid knockdown bit.ly/46GUn2c 1/4

Don't forget to apply to our position in Evolutionary Genetics at U of South Carolina! In my experience it is a fantastic place to start a new lab, with friendly and supportive colleagues and many junior faculty in EEB! Review starts in 1 week (Oct 1)!

New PrePrint from the Vecchiarelli and Mosalaganti (@shyamalm.bsky.social) labs! 🧵 Collaboration with the Giessen and Pi labs Congratulations to co-first authors Y Hoang (@hoanghamyy.bsky.social) and Pankaj Jadhav! www.biorxiv.org/content/10.1...

🦠 Mycobacteria aren't just tough, they're interior designers! 🦠 Check out our latest #preprint 🚨, led by our PhD student @camimille.bsky.social , where we show that #Mycobacterium tuberculosis builds secret cytoplasmic membranes to adapt its metabolism and sneak past immunity 🤫 Thread coming soon!

Time for some insights into our latest #preprint Using cryo–electron tomography, we peeked inside different #Mtuberculosis strains, and a couple of other mycobacteria.🧐 Surprise: some species, especially the host-adapted ones, build intracytoplasmic membranes (we call them MIMs)! 🦠

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture. buff.ly/j3TSIkn

Really excited to share my first paper from the Whitney lab, alongside an amazing grad student, Polina. Here we identify a chaperone family required for the folding of a central domain of T7SS toxins, and solve the structure of the chaperone-toxin complex. www.pnas.org/doi/10.1073/...

How complex functions, with important physiological and evolutionary impacts get repeatedly and efficiently transferred across genomes? That’s what we explored using one of the fastest-evolving loci in Bacteria: the capsule locus. The paper: www.biorxiv.org/content/10.1... Thread👇

A thousand bravos for Núria Ros-Rocher, who just secured a permanent @cnrs.fr researcher position in our lab. These positions are (too) rare but give much-needed job security to young scientists and allow long-term projects. Núria will dive deep into the natural history of C. flexa 🧪🌊 #ProudPI

Anyone interested in some Wolbachia T4SS goodness? And other weird stuff? Started years ago by @bigvirushunter.bsky.social in my lab, pulled over finish line by awesome collaboration w Matt Swulius, Carrie Shaffer, & Mohammed Kaplan (don't tthink they're on bsky) www.biorxiv.org/content/10.1...

one small consolation of being a 60+ year old investigator is the ability to submit to 𝘔𝘈𝘛𝘜𝘙𝘌 family journals — sure they’re low impact (for our knees) but they have an early bird special if you submit between 4:00 and 5:30 on weekdays

Saw this photo of Adah Elizabeth Verder (1900-1997) in another post, accompanied by comments on mouth pipeting. When I took intro microbiology in 1979, one of the first lessons in lab was mouth pipeting technique. Pay attention, and it was the most accurate, fastest method available. #MicroSky

The chance encounter of an economist, a pathologist and physicist resulted in a highly multidisciplinary study that used an epidemiological model to trace the spread of rumors in the early days of the French Revolution. I had the chance to cover this fascinating research for @nature.com

We are recruiting 2 postdocs to work on bacterial motility using a combination of cryoEM, FLM and MD. An exciting collaboration with Kirsty Wan @micromotility.bsky.social Wolfram Moebius @wolframmoebius.bsky.social and Daniel Kattnig. Please see links in the thread below!
