1/ 🧵 Two classic mitochondrial pathways the TCA cycle and OXPHOS are taught as linked but distinct pathways. I’m happy to share our new work out in @cp-cell.bsky.social showing that in Acanthamoeba they're physically linked—with a TCA enzyme incorporated in ATP synthase. www.cell.com/cell/fulltex...

Acanthamoeba ATP synthase structure reveals the TCA cycle is tethered to OXPHOS
Acanthamoeba castellanii, a pathogenic amoeba, belongs to an evolutionary branch distinctly removed from humans and fungi. Cryo-EM of the organism’s ATP synthase enzyme using raw mitochondrial lysates...

Our work investigating the cooperation between gene expression machines is now online @cellpress.bsky.social. Check it out if you're interested in high-throughput #cryoET, transcription and translation, or using structural biology to quantify gene expression in cells! 🔬 www.cell.com/cell/fulltex...

Single-cell visual proteomics of a minimal bacterium reveals structural coordination of gene expression machineries
Cryo-electron tomography (cryo-ET) resolves and quantifies an almost complete view of bacterial translation, revealing how gene expression machineries coordinate across the processes of transcription,...

Now on Arxiv: arxiv.org/abs/2608.10029 Led by grad student Matthew Giammar and collaborator Alex Strang, we provide a fast algorithm to calculate a low rank approximation to large (>100 million row) matrices with high fidelity that will accelerate template matching.

A fast diagonalization algorithm to enable singular value decomposition of large matrices for efficient template matching
Many computational problems possess the following three features: (1) the problem could be solved efficiently if a linear operator could be diagonalized, (2) direct diagonalization is infeasible due t...

A new preprint from the @archaeon-alex.bsky.social and Joey Davis (MIT) labs! We solved the structure of the ribosome from the archaeon Haloferax volcanii and discovered a new highly conserved ribosome hibernation factor that we named AHA (AMPKγ–HPF from Archaea) 🧵⬇️ www.biorxiv.org/content/10.6...

Asgard archaea reveal the conserved principles of ESCRT-III membrane remodeling
Asgard archaea have two ESCRT-III subunits with the conserved traits that drive stepwise membrane remodeling in eukaryotes.

New development in #cryoEM specimen preparation from the Efremov lab that enables structure determination from a single plate of cells. Will be exciting to see how this revolutionizes low copy structure determination and investigations from native sources. www.biorxiv.org/content/10.1...
