Per què hi ha casos de tuberculosi a l'Institut B9 de Badalona? Els últims brots de tuberculosi han posar de relleu la incidència d’aquesta malaltia, una situació peculiar, ja que semblava fa uns anys gairebé erradicada. Una percepció clarament equivocada. www.youtube.com/watch?v=nclb...

Trying to come up with a way to help explain immunology to a general audience on social media, any critiques are welcome. Here is a few images I have made for how i am thinking of approaching it. 🧪

Many bacteria use #QuorumSensing to control genes based on population density. @jrchandler.bsky.social &co explore a @plosbiology.org study showing that in P. aeruginosa, 2 QS circuits activate each other, enhancing robustness & explaining redundancy 🧪 Paper: plos.io/3I7DhRG Primer: plos.io/4niSZZd
System architecture of quorum-sensing circuits. Top left: Quorum sensing in proteobacteria. A signal synthase (blue) produces a diffusible signal (black circles) that binds to a cytoplasmic signal receptor (light blue). When the signal reaches sufficient concentrations, it binds to and activates the receptor, which causes changes in transcription of target genes. Top right: The las and rhl systems of P. aeruginosa. The lasB gene is activated by both systems. The specific acyl-homoserine lactone signal molecule is pictured for each system. Bottom: Illustration of circuit architecture: reciprocal, hierarchical, and independent. Indicated below are the relative levels of lasB gene activation and sensitivity shown by Thomas and colleagues in experimental and modeling studies.

🍂 🦠 🧪 David Baltimore 1938-2025

1975 Nobel Prize for the discovery of reverse transcriptase, the enzyme that transcribes RNA to DNA

'David Baltimore, a biologist who in 1975 won a Nobel Prize for a startling discovery that seemed to rock the foundations of the fledgling field of molecular biology, died on Saturday at his home in Woods Hole, Mass. He was 87.'

An organism's internal state & behavioral outcomes are shaped by experience. This study reveals a #neuropeptide relay pathway, neuronal & non-neuronal, which orchestrates #SynapticPlasticity & context-dependent shifts in #mating duration in male #Drosophila @plosbiology.org 🧪 plos.io/4n8aUSV

Legend David Baltimore died yesterday. He understood the way things should work: "the real contribution of MIT is that it doesn't take itself too seriously. It takes ideas seriously, but the people are relatively informal. They are not self-aggrandizing the way academics can be."

No sé quina és la dada a casa nostra, però potser ho facilitaria tenir una baixa per maternitat que cobrís aquests primers 6 mesos sencers, en lloc d’haver de fer equilibris per mantenir una lactància materna exclusiva a demanda mentre es treballa… 😒

What kinds of life are possible? How can we know about that regarding life origins? Here's our new paper to appear in @royalsocietypublishing.org with C Kempes & S Stepney. Check our space of the possible for replicators. @sfiscience.bsky.social @manlius.bsky.social www.preprints.org/manuscript/2...

Can a virus help uncover Turing patterns in nature? In this @commsbio.nature.com paper, researchers show how the tulip breaking virus triggers the expression of a pigment that can display a broad range of (observable) stripe patterns @philipcball.bsky.social

Can cellular life be created in the lab? We are not yet there, but clearly getting closer! Check this paper where a new scenario for protocell replication is presented by Job Boekhoven and co-workers @manlius.bsky.social www.cell.com/chem/pdf/S24...

Delighted that my friend @lmprida.bsky.social, a great scientist, has been named director of the new Cajal Neuroscience Center at @csic.es. Thirty years ago, as a graduate student in my Lab she published her first paper on chaos control in neural networks. I can't be more proud and happy.
