First pre-print from the Lucas Lab led by Matthew Giammar and @joshdcryoem.bsky.social online today! We develop a new, extensible Python implementation of 2DTM and apply it to build pixel size optimization, constrained search and characterize molecular motions in situ www.biorxiv.org/content/10.1...

Very excited to announce that my first, first author paper, is now on BioRxiv! In this paper we unambiguously show #COPII coated vesicles in unperturbed human cells for the very first time!! Make my day and check it out! www.biorxiv.org/content/10.1... #Cryo-ET #TeamTomo #Cryo-CLEM ❄️🔬❄️🔬❄️🔬❄️🔬

I'm at the OHSU PREP research symposium and I am so impressed with our trainees, they present and know their project background better then many a graduate student. All the more I'm filled with rage about the cancellation of this wonderful #NIH program 🤬

I know print journals aren't exactly on everyone's radar these days, but we’re still geeking out that our latest study—led by the brilliant @attychang.bsky.social—landed the cover of the April issue of JCB! 🤩 @zidlab.bsky.social @tomo.science @hamid13r.bsky.social

Since @stephanieaw.bsky.social left the lab to start her group at Vanderbilt, we've been talking regularly on the ups and downs of academic science. We started recording... The Tortured Proteins Department open.spotify.com/show/10PHVou... (science with a small dose of running and Taylor Swift)

For #teamtomo, context is everything. We highlight the power of #surfacemorphometrics in guiding STA and quantitatively assessing the impact of these structures on the local environment. 1st collab paper w/ @zidlab.bsky.social (hopefully many more to come!) @tomo.science @hamid13r.bsky.social

Happy to share that the final version of record for our ( @nanigrotjahn.bsky.social) #teamtomo mitochondrial cotranslation story is online at @jcb.org! We combined STA with surface morphometrics to learn how ribosomes bind to and alter mitochondrial membranes in yeast. rupress.org/jcb/article/...

🚨Members of #teamtomo!🚨 We invite you to submit abstracts to our ❄️🔬Cryo-electron Tomography: Progress and Potential session at Microscopy & Microanalysis (M&M) 2025! sample prep, data processing, structural biology, cell biology —we want to hear from you! DEADLINE: February 18 @tomo.science

Had the incredible opportunity to present my work at #EMBOinsitu workshop in Heidelberg. It was filled with fantastic science and new friends! #teamtomo

I am participating in calls today with top law firms and some university leaders to discuss this situation. My amateur take is that Stuart Buck is right that this is clearly illegal based on NIH-related law and also probably from more general admin law Timing of suits and plaintiffs still questions

I am deeply appreciative of the messaging coming out of OHSU leadership about their plans going forward and their commitment to research in the face of changes at NIH and NSF - the best communication we've gotten while I have been here. Still kind of terrified about the future though...

Hey #teamtomo, if you often find yourself using the excellent membrain-seg from @lorenzlamm.bsky.social et al., you might find my napari plugin "napari-segselect" useful. Let's say your tomogram contains the edges of two bacterial cells, each with a membrane and cell wall:

Extremely excited to be joining the vibrant community of the Vienna BioCenter to build up cryo-ET and cryo-FIB milling on campus soon!

What a great time to be preparing for my labs first NIH proposals...

Portland Thorns and WNBA team unveil plans for joint practice facility www.oregonlive.com/portland-tho... [via @oregonian.com]

Starting the week off STRONG with the urge to doomscroll...

Prof. Martin Beck’s group @mpibp.bsky.social publishing some beautiful #cryoET work investigating TRiC, a chaperonin essential for maintenance of cellular homeostasis. This work provides TRiC architecture, conformational dynamics and spatial organization. #teamtomo www.nature.com/articles/s41...

I really need this to be true

Portland Thorns FC have announced its 2025 preseason roster as the team begins training camp. Portland will begin the preseason with 29 players, 18 of which return to the Rose City from last year’s squad

Hard to believe but this week has been worse than I expected... Not sure where we go from here.

Big time fomo 😍

looking forward to my first trip to Australia for this exciting conference! #teamtomo

The first chapter opener in my Biochemistry book is a picture of Carol with Peter Agre on the morning of the prize announcement. It still makes me smile every time I see it. Be generous with your graduate students and other co-workers. Giving them credit and opportunities can change their lives.

Lynn William lives for rivalry matches against Portland.

Which Plan was zero embargo for everything? Public funding for public versions of record is the way to go!

Thorns games will not be the same next year. So glad I at least got a year of watching all her and Sinc's games.

Thanks everyone for attending and asking great questions. And thanks EMS for hosting!

I need to get back on the Krios!!!

FIB perspective lamellae = Rothko paintings

Tomorrow(!) morning at 9AM pacific, I am giving a webinar for EMS discussing the surface morphometrics pipeline and our approach to contextual structural biology #teamtomo. Free to attend, hope to see you all there! us06web.zoom.us/webinar/regi...

Been wanting to try ais for a minute, no time like the present!

Grateful for having contributed to this work by the Isabelle Baconguis group, who solved eleven (!) new structures of hASIC1a to show that open states require linear transmembrane helices, while desensitized states display a dazzling structural diversity www.biorxiv.org/content/10.1... #ionchannels

It has been clear all week in portland, which makes for some VERY cold bike rides but also some incredible views from my office!

Advice for prospective PhD students in Quantitative Biology - written by an amazing UCSF student (and roton-who-got-away) Hersh Bhargava (incorporating my input!) hershbhargava.com/writing/appl...

@nanigrotjahn.bsky.social, PhD, unveiled how mitochondria—our cells’ ‘powerhouses’—act as stress sensors, shaping cellular health and contributing to diseases like cancer and neurodegeneration. Her work uses cutting-edge imaging to unlock these secrets. (9/10)

Inaugural post sharing a newly updated version of our little protocol for high quality fiducial removal in #CryoET processing

Pleased to share the peer-reviewed version of our latest work on resolving the complexities of a-crystallins/sHSP's: www.nature.com/articles/s41... A timely release of this story... as it is a great setup to the next one, coming soon!!

Oh my. This is just gorgeous from Misha Kudryashev's lab (I don't think he's here yet?). Love to see it. V ATPase resolved directly in synaptic vesicles 🤤 Lots of other neat observations in there also. Congrats to all involved! www.pnas.org/doi/10.1073/...

Great community assessment here. Still unable to find alternate conformations. Protein dynamics the next big obstacle clearly 👀

Has anyone encountered the issue of DM3 crashing and taking TIA with it during long tomo collections? If so, did you find a solution? #Teamtomo #CryoET

A fun journey of full-length EGFR with Dan Leahy and @edwardmarcotte.bsky.social at UT Austin @utaustin.bsky.social. See below: Structure and organization of full-length Epidermal Growth Factor Receptor in extracellular vesicles by cryo-electron tomography www.biorxiv.org/content/10.1...

Hello Bluesky, the Nogales lab is very excited to join this growing community 🦋 We look forward to sharing our work here and to connect with other scientists!

Reflecting on my two contributions to science that will never make my biosketch: 1. An easy to use lab website that has been copied dozens of times (fraserlab.com) 2. Running a coffee co-op in grad school - I claim partial credit for all the Cheng, Frost, and Fraser lab discoveries from 2016 to 2019

We are opening in January of 2025 at UCLA: SamelsonLab.org We combined classic biophysical techniques with systems genetics in iPSC-derived cell types to explore how proteins aggregate and how cells control protein aggregation. Multiple positions are open: SamelsonLab.org/join/ Join us!!

And I have some examples of the punctures, they're like little cytoplasm volcanoes. They're seemingly pretty rare FWIW

Big #teamtomo things happening at OHSU! The future of cellular structural biology is tissue, and Cathy, Aya, and Eric have inspired me to start dipping my toes into multi-cellularity since I started there.
