Optical tweezers reveal forward and backward motion is symmetric in molecular shuttling In molecular shuttles, a ring molecule is threaded onto a linear molecular strand and can move between two portions of the strand, called stations, in response to external stimuli. Chemical stimuli, l...

A una molecula le "cuesta" lo mismo subir que bajar la barrera energética entre dos estados metaestables. @emiliomperezlab.bsky.social @3mlab.bsky.social lo observan por primera vez en nanomaquinas moleculares 👉

Ismael Plaza defended successfully his thesis "In Singulo characterization of the real-time kinetics of the human mitochondrial DNA replisome", directed by Prof Borja Ibarra @3mlab.bsky.social @imdeananociencia.bsky.social
🎓 Congratulations Doctor!

Transition-path times of individual molecular shuttles under mechanical equilibrium show symmetry This study explores microscopic reversibility to understand the operation of molecular devices.

Paper with @emiliomperezlab.bsky.social and @3mlab.bsky.social et al. in print! Experimental energy landscape calculated (journals.aps.org/pre/abstract...) from the Onsager-Machlup approach for systems in mechanical but not necessarily thermodynamic equilibrium.

Transition-path times of individual molecular shuttles under mechanical equilibrium show symmetry Measuring individual trajectories during the operation of synthetic devices is crucial for a thorough understanding of this operation. Here, we use op…

Single molecule approaches across the central dogma! Genomics, imaging and theory! Very excited to host the first edition of Gene regulation, one molecule at a time this July @embl.org! Great lineup and many abstract selected talks!

The known unknowns of the Hsp90 chaperone An exploration of the unanswered questions in how the molecular chaperone Hsp90 supports protein homeostasis, and how single-molecule techniques could drive future breakthroughs in answering them.

What a way to start 2025! Our review on the Known Unknowns of the Hsp90 Chaperone has been published!
Huge thanks to Laura Silbermann and Benjamin Vermeer for all of their efforts, and to @scisonja.bsky.social for the great collaboration :)

First paper of our lab today @natureportfolio.bsky.social by Nussi!

We provide a real-time movie on how #transcription and #translation cooperate using #single-molecule FM: we find long-range #ribosome/ RNAP communication mediated by #RNA looping!
