Great start to #CellBio2025 in Philadelphia with "The Peroxisome Renaissance: From Molecular Mechanisms to Cellular Functions" session organized by @fredmast.bsky.social. Really enjoyed speaking alongside Bonnie Bartel, Michael Skowyra, Jie Sun, Francesca Di Cara, PhD, and Peter Kim. 🙌

New preprint out! We show that PROTAC-induced ubiquitination can bypass canonical ERAD to degrade ER membrane proteins. Wonderful collaboration w/ @dannomura.bsky.social and huge credit to grad student superstar Sydney Tomlinson! www.biorxiv.org/content/10.1...

CryoET of microbes inside an animal organ? Yes it’s possible! Check out our new preprint showing how we did it! What an amazing collaboration with amazing scientists who made this possible!

Prohibitins aren’t hanging out just anywhere in the membrane — they prefer the 💁‍♀️💎✨VIP section💅🪩🥂 Lab all-star @mmedina300kv.bsky.social maps these microdomains using cryo-ET + surface morphometrics. s/o to #teamtomo #cryoET co-authors @hamid13r.bsky.social @attychang.bsky.social @baradlab.com

Excited to share the peer-reviewed version of our work, now online in @embojournal.org! Big thanks to our reviewers and @hvodermaier.bsky.social for facilitating this process. Looking forward to continuing this fun collaboration with @michaelnadbio.bsky.social! www.embopress.org/doi/full/10....

The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor. The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2. www.leadingedgesymposium.org/apply/

Zara Weinberg passed away earlier this week. She joined my lab earlier this year when her postdoc lab formally closed. She was a brilliant scientist, supportive mentor, dear friend, avid music fan, rabid believer in public transit, open science champion, and above all just an amazing human.

Zara Weinberg was a brilliant light both in and out of science. She changed the lives of everyone she interacted and loved for the better. Her legacy will live on through all of us and we will fight for a better world on behalf of her memory.

Check out our new publication, a collaboration with Giovanni Luchetti and Vishva Dixit @ Genentech. We show that the E.coli effector NleL inhibits intestinal epithelial cell extrusion after #inflammasome activation via degrading the kinases ROCK1 and 2!! www.nature.com/articles/s41... Explainer 1/8

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

Nominations for the June Almeida award for Mid/Senior-Career Women in Cryo-EM are now open! Submit your nomination via this link www.biophysics.org/awards-fundi... by November 14th to recognize an exceptional woman in our community.

Events celebrating women in electron microscopy are rare, which made my recent experience at the Ernst Ruska-Centre (ER-C), Forschungszentrum Jülich, Germany, truly special. I had the privilege of not only attending but also serving as a young keynote speaker at this inspiring gathering. 🎉

Lab’s 1st preprint! Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate. @cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation. He is on the job market!
