Hurray, it is finally out! Meet bacteriophage Bxb1 - the subject of my first full-phage cryo-EM study. My structures are beautifully complemented by the Park Lab’s cryo-ET analysis, shedding light on mycobacteriophage structural changes during infection.

Wooo tried again at a different pharmacy last night and got it - and the flu jab, too. Glad it worked this time! Feeling relieved, if still angry that a repeat attempt was necessary. Nobody should have to jump through hoops to protect themselves and their community.

Well, I just was denied the COVID vaccine in Cleveland, Ohio. I can’t begin to express the rage I feel at being barred from protecting my vulnerable loved ones. My “senators” just got voicemails - I will keep calling until access to these safe and effective vaccines is restored. My body, my choice.

Join me in donating to ABRCMS. For many of us early in our careers (and for many of us now), this is THE conference. Let’s make sure future generations get the same experience.

I was told if each poster judge donated $25, their goal would be quickly met, but I think we can do better! 🙏🏾💪🏾

Some eye-catching #TeamTomo work here. Congrats to @kfreeman.bsky.social and all the authors! 🧪🧶🧬🔬

stunning atomic-level imaging (Cryo-EM, cryo-ET) reveals how 𝐛𝐚𝐜𝐭𝐞𝐫𝐢𝐨𝐩𝐡𝐚𝐠𝐞 Bxb1 reshapes its tail tip to breach the mycobacterial cell wall and deliver DNA to the cytoplasm

can inform precise targeted phage therapies for TB and NTM infections

Thanks, Vivek! The biggest challenge now is deciding which phage to tackle next. Hope all is well!

It was a pleasure to collaborate with you all! Here’s to many more fun projects in the coming years 🥂

Thrilled to have contributed to this exciting work! Great collaboration with the amazing Krista @kfreeman.bsky.social & Graham Hatfull lab. Huge thanks to the Park lab for this fantastic opportunity 🙌 #CryoEM #CryoET #phage #mycobacteria

Thanks :)
Structural biology is equal parts art and science, for sure!

Do you love phages? Other viruses? Cool science done by cool people? Check out this paper by my former bay mate @kfreeman.bsky.social and colleagues that sheds light on the cool molecular machines that are phage tails.

Huge thanks to our many collaborators, near and far, who helped push the science to the next level.

And, especially in these times, thank you to the NIH for funding this research and me as an early career scientist. It has made a world of difference in my life.

I delighted in every step of this project, from cesium-banding the phages to choosing a color scheme and polishing the figures. What a treat that I get to do this for the rest of my career!

Thanks for making this starter pack, Joscelyn! Awesome to see so many MOSAIC scholars assembling here in the bluer skies. So happy to connect!

I started a list of MOSAIC scholars to help find and support each other. I'm sure I've missed many people, lmk if you want to be added!

Yeah, I did indeed assume these were eukaryotic viruses… thanks for the nudge to look again! Phage diversity just blew my mind again!

Definitely hope to see some tailed phages represented soon too. Long & flexible, short & stubby, contractile… so much room for creativity!

Oooo maybe I missed them (I just searched “phage” in the search bar) - let me look again! Thanks!
kfreeman.bsky.social
LOVING the NIH BioArt effort! BUT… where are the phages?? Hoping to see some in the official release! Anyone know if there’s a mechanism to request additions?

Thanks!

I, too, love phages and am eternally grateful that my autocorrect has learned that about me!

I’m pleased to share that I’ll be joining Case Western Reserve University as an Assistant Professor of Physics, starting July 2025! Looking forward to returning to my Physics roots while continuing to investigate the wonderful world of phages. :)
