Did you know the cell wall of mycobacteria isn’t just for protection? 🧱👀 Here, Mycobacterium marinum sheds its outer capsule right after being eaten by Dicty! A sneaky move that affects even nearby cells… #FluorescenceFriday #Mycobacteria #CellBiology #Infection #3Rmodels #Phagocytosis

Symposium: A Dutch Perspective on Mycobacterial Infections On the 24th of March 2025, World TB day, we organize a symposium to connect the Dutch scientific community working on mycobacterial infections. We will cover all aspects of tuberculous or non-tubercul...

Looking forward to seeing some excellent talks and posters today: "A Dutch Perspective on Mycobacterial Infections". #Mycobacteria #TB Amazed to learn so much interesting research to understand TB and non-TB mycobacterial infections is going on in NL: www.universiteitleiden.nl/en/events/20...

For the 5th time, the DANish-GERman (DanGeRoUS)
#Mycobacteria Club meeting will take place today at the @fzborstel.bsky.social. Experts from Denmark, Sweden, Romania, Moldova, Korea & Germany will present & discuss clinical cases of #NTM- and #TB diseases. We wish all participants an exciting day!

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...

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.

Rising temperatures increase added sugar intake disproportionately in disadvantaged groups in the USA - Nature Climate Change Few studies have evaluated how climate change may affect dietary habits and nutritional health. Here, using transaction data in the USA, the authors show that added sugar consumption increases with temperature, especially between 12 °C and 30 °C, with stronger effects among lower-income and lower-education groups.

Global warming may be associated with an increase in added sugar intake in the form of sugar-sweetened beverages and frozen desserts in the US, especially among more socioeconomically disadvantaged groups, according to study in @natclimate.nature.com: spklr.io/63327BH7qP

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."

Real-world impact of nirsevimab immunisation against respiratory disease on emergency department attendances and admissions among infants: a multinational retrospective analysis Nirsevimab had a clear impact in reducing attendances and admissions for infants with bronchiolitis aged <6 months in Catalonia. However, the impact on older infants was less clear.

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… 😒

A cartoon titled ‘The Life of a Scientist’. (The life is depicted as a set of steps, three up then three down with a character on each) Baby: Such a mysterious world! Child: I must search for answers Young adult: Each answer leads me to more questions Middle age: ... At least I've got lots of questions Old age: Ok, I guess questions are my thing now From grave: Such a mysterious world!
