🚀 Our new paper is out @natmethods.nature.com!

Kuffer & Marzilli engineered conditionally stable MS2 & PP7 coat proteins (dMCP & dPCP) that degrade unless bound to RNA, enabling ultra–low-background, single-mRNA imaging in live cells.

Field notes from a weekend PI at the #microscope: vesicle cargo lanes lighting up in real time like @FedEx. This is the ML1N PX domain in a fibroblast. Hot damn, there’s mind-blowing action under the surface of cells: this video shows 2 min of time 🤯 #Cellbio #MicroscopyMonday #SciArt #SciComm

I’ll say it since Daniel Stabley won’t: his NeuroImaging Lab didn’t just ride the wave they built it While others were still decoding the manual, they had the Developmental Neurobiology Dept MOSIACing like pros. Ain’t no edge but the cutting edge #MicroscopyMonday www.biorxiv.org/content/10.1...

How does tumour heterogeneity arise? How can we predict cancer cell plasticity? In 2 new studies, we trace #glioblastoma heterogeneity to a spatial cancer cell trajectory w. multimodal cell atlassing bit.ly/4mkrWgs & predict plasticity w. snRNA/ATAC+deep learning bit.ly/3FbI6Ic 🧵

The word GET is totally off base for NIH funding. Institutions don’t get NIH dollars—they earn them. Grants are fierce competitions where only the best ideas push science forward. My last two grants ranked in the top 1% & 2%, outcompeting 98%. Like a VC pitch—except we’re curing diseases.

🧬 We’re excited to introduce D&D-seq, a single-cell technology that maps DNA:Protein interactions through molecular footprinting. Check it out here: biorxiv.org/content/10.1... #Genomics #Epigenetics
Single-cell mapping of regulatory DNA:Protein interactions
Gene expression is coordinated by a multitude of transcription factors (TFs), whose binding to the genome is directed through multiple interconnected epigenetic signals, including chromatin accessibil...

After long-time review, #nanoSPLITS is finally published. I am deeply grateful to my colleagues who made this work possible, especially @cajunscience.bsky.social. I am also grateful to the support of our single-cell proteomics community during the peer review on Nature Communication!
