We develop an epiblast complementation strategy that enables the generation of mice from PSCs in a single step. With further optimization, we hope to develop this approach into a broadly applicable platform for generating genetically engineered mice and potentially other species.

Our multi-immersion oblique plane microscope manuscript is online now.

A light-sheet system that can be adapted to different imaging tasks, including a continuous volumetric correction for imaging in media of (theoretically) any refractive index.

Our first protein 🥩 design paper! 🤠

Check out Minkyu's tour de force on T-REX 🦖, an agentic protein design controller for de novo binder design!

TLDR we treat protein design as an online allocation problem over heterogeneous tools (Proteina-complexa, Boltzgen, Bindcraft, ✨ etc), use 🤖 agents to reason over what tools + settings to run, designed a granular classification system to manage the agents (e.g. Rescue🛟/Explore🔎/eXploit🚀), that is all orchestrated with a deterministic controller to efficiently brrr the GPUs. 💸

T-REX 🦖 is fully open source: github.com/ml-struct-bio/…

Preprint: biorxiv.org/content/10.648…

Please let us know if you have any feedback!
Excited to share T-REX 🦖: Target-adaptive Rescue-Explore-eXploit, an agentic campaign controller for high-throughput de novo protein binder design!

T-REX treats protein design as an online agentic allocation problem to leverage diverse tools with efficient GPU usage 🧵

What a fun surprise to find that our work has been featured in a @JCellBiol spotlight!! Many thanks to Carlotta Peselj and Nora Vögtle for the great write up!
Spotlight: Carlotta Peselj and Nora Vögtle discuss work by Yan et al. of the @nieminm lab (hubs.la/Q0485RBr0) that provides a quantitative framework for measuring the strength & targeting efficiency of various #mitochondria targeting presequences hubs.la/Q0485VJZ0

New preprint from the lab, led by the ever-talented grad student Tessa Lochetto
@tloch_! We find that loss of Pptc7 decreases lean mass, induces skeletal muscle dysfunction, and causes metabolic derangements in adult mice: doi.org/10.64898/2026.… /1

Take a look at our new paper on the structure of the EHD2 that, upon oligomerization, forms rings that remodel the plasma membrane and form caveolae.

Beautiful work by Elena, Vasya @v_mikirtumov, Jeff & Oliver Dumke's team; take a look: nature.com/articles/s4146…

Returning to Science Twitter briefly to thank the UTSW newsroom for their kind story on my New Innovator award. Humbling experience. A few thank yous to follow, as most haven't switched to the "other" place. :)

Cryogenic electron tomography (cryoET) is a revolution already in motion!
@MishaKudryashev argues that in situ structural biology is exploding, forcing us to rethink cells, molecules, and collaborations: tinyurl.com/4x4bf9ze

EHD2 forms rings on caveolae necks, in contrast to most EHDs forming helices. We determined its structure on membranes and show that N-term acts as a spacer

Building atomic models to cryo-EM maps of huge molecules is intimidating: crowded, uncertain copy numbers, variable resolution ...

@theliulab and team show how cross-linking MS can be used to build novel models of unknown complexes, like a giant virus❄️ ❄️biorxiv.org/content/10.110…

Last night my brilliant friend with 20 years of expertise in Neuroscience including a decade at NIDA was fired because she was recently promoted for her outstanding performance and it triggered the probation period.

This is not making NIH more efficient, this is not making us healthier, this is not punishing the people who misled the public, this is destroying America’s talent.

Her work is instrumental for testing whether new medications to fight addiction are safe and efficacious before they are tested in humans. now that research is at risk.

She was the backbone of the lab the most senior person. So much knowledge, talent, know how, wasted, so much science destroyed for the wrong reason.

Sigh…

"Don't be afraid!"

Randy Schekman says that the most successful scientists are willing to take risks. He uses 2024 chemistry laureate David Baker as an example of how embracing risk can lead to significant rewards.

Before Baker transitioned to researching structural biology he ein transport in yeast. Prior to that, he earned a bachelor's degree in philosophy and social science, demonstrating that no career change is too drastic.

Schekman was awarded the 2013 medicine prize jointly with James Rothman and Thomas Südhof for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells.
