Structural cell biology, biophysics, fluorescence, electron microscopy, art, nature. All opinions are my own.

Researchers like Ben Larson and Glen D’Souza are piecing together the world of killer microbes, including why they turn on each other and if their tiny weapons could be harnessed to fight disease. Listen to the podcast now: www.sciencefriday.com/segments/kil...

Swords, cannibalism, poison: inside the world of killer microbes

Some microbe species have evolved to stab, bomb, cannibalize, or poison each other. Can we harness their weapons for good?

🔬🚀 It's out! Run 100s of imaging experiments before touching a microscope. #VLab4Mic reproduces them in silico from PDB/AlphaFold to help you image right first time. From rockstars Damián Martínez & Bruno Saraiva, inaugural preprint of @mariodelr.bsky.social new lab www.biorxiv.org/content/10.6...

Congratulations to Damián Martinez, Bruno Saraiva, @taylashakespeare.bsky.social, @wmarkbates.bsky.social, Dylan Owen, @christlet.bsky.social and @henriqueslab.bsky.social We hope VLab4Mic helps researchers design better experiments and ask better biological questions 💻 vlab4mic.henriqueslab.org

Better vitrification = better cryo-ET. We've opened an RFA for two-year grants to advance vitrification techniques for biological samples—welcoming applications from researchers in heat transfer, cryogenics, and materials science. Apply here: bit.ly/4uip6eJ

And now it's out! Happy that PNAS selected for the cover this SEM image snapped by @samjlord.bsky.social, one of the most evocative visualizations of Euplotes that I have ever encountered. www.pnas.org/doi/10.1073/... Stay tuned for what is shaping up to be some fascinating follow-up in the lab...

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells? www.biorxiv.org/content/10.1... Video by Vittorio Boscaro. 1/n

A new paper in #ScienceSignaling visualizes the delicate ebb and flow of receptors within neurons via the unusual process of transcytosis—helping answer how these cells maintain their function and connectivity in vivo despite their spindly, elongated nature. https://scim.ag/4dlUGl8

Transcytosis-mediated anterograde transport of the receptor TrkA mediates the formation of presynaptic sites in sympathetic neurons

Sympathetic innervation requires transport of TrkA from the soma surface to the axon.

OK, here we go. This is the good stuff. An awesome and technically innovatie new paper by good friends of mine including @profsharona.bsky.social, Bill Zagotta, and my next-door science neighbors Professor Suzanne Hoppins and grad student Sophie Hurwitz. 1/

Time-resolved tmFRET reveals GTP-coupled conformational changes in Mfn1

Hurwitz et al. leverage a novel FRET-based approach to quantify conformational dynamics of Mfn1, a member of the dynamin superfamily that mediates mitochon

Throwing the switch for our electron microscope installation. With these fabulously complex instruments, something always goes wrong at first light. Roseann Rosanna Danna’s (Gilda Radner) expression, “It just goes to show you, it’s always somethin’” is powerfully accurate.
