Scientist. I perform experiments at work and out of it (matching own clothes). I also write/talk(science and things)/climb/bake/dance/draw…

Years from 1953 to 1968 were mindblowing for MolBio. Double helix, central dogma, genetic code... Since then, any related discovery has been that earthshaking. I wonder where the next mine of scientific discoveries is for understanding how life (or the world) works. I guess in physics... ideas?

Cuando escucho noticias trágicas en la tele, y veo con horror cómo les ponen banda sonora (normalmente emotiva, a veces Bob Dylan o similar...), disfrazan de cine lo que no tiene ni una pizca de belleza. La actualidad sobre la desgracia no debería plantearse con sentido estético. Porque no lo tiene.

Breaking News: Jane Goodall, one of the world’s most revered conservationists, died at 91. Her discoveries in the 1960s about how chimpanzees behaved in the wild broke new ground and represented what was called “one of the Western world’s great scientific achievements.” nyti.ms/42kpGxt

Just out! Want to use quorum sensing (QS) for cell–cell communication? Check this out — you might find it useful! Kudos to Paula Múgica 👏 Standardized Quorum Sensing Tools for Gram-Negative Bacteria | @pubs.acs.org @acs.org #SyntheticBiology @sevaplasmids.bsky.social pubs.acs.org/doi/10.1021/...

Standardized Quorum Sensing Tools for Gram-Negative Bacteria

Engineering synthetic consortia to perform distributed functions requires robust quorum sensing (QS) systems to facilitate communication between cells. However, the current QS toolbox lacks standardized implementations, which are particularly valuable for use in bacteria beyond the model species Escherichia coli. We developed a set of three QS systems encompassing both sender and receiver modules, constructed using backbones from the SEVA (Standard European Vector Architecture) plasmid collection. This increases versatility, allowing plasmid features like the origin of replication or antibiotic marker to be easily swapped. The systems were characterized using the synthetic biology chassis Pseudomonas putida. We first tested individual modules, then combined sender and receiver modules in the same host, and finally assessed the performance across separate cells to evaluate consortia dynamics. Alongside the QS set, we provide mathematical models and rate parameters to support the design efforts. Together, these tools advance the engineering of robust and predictable multicellular functions.

Just published! Paula Mugica has standardized a set of #quorumsensing tools for its use in gramnegative bacteria. Their utility range from the development of #synbio #circuits inside a cell to what is even cooler: for cell to cell communication :) pubs.acs.org/doi/10.1021/...
