Tried #pottery #wheel-throwing. It looks simple until the clay starts spinning and suddenly every small movement matters. Centering the clay was hardest, but also most satisfying when it finally worked. Messy, imperfect, and surprisingly calming, definitely not my last attempt.

New study propose that Bordetella adheres to the tips of cilia and then deploys multiple FhaB adhesins to migrate to the base of the cilia forest, where the bacteria resist removal by the mucociliary “escalator” that normally clears the respiratory tract of microbes www.science.org/doi/10.1126/...

Bacteria deliver a microtubule-binding protein into mammalian cells to promote colonization
Pathogenic Bordetella bacteria use protein adhesins to infect the ciliated respiratory epithelia of vertebrate hosts. In this work, we show that the filamentous hemagglutinin FhaB adhesin of Bordetell...

Enterobacter species are rising as tough nosocomial pathogens, with bacteremia linked to high mortality. Intrinsic AmpC β-lactamase and widespread fluoroquinolone resistance shrink options, making carbapenems critical. www.tandfonline.com/doi/full/10....

Yes, having a spirit of reconciliation is a way forward. There is hope to mitigate the aggressiveness of those who have not wanted to understand! Thanks MIRRI @pravrahi.bsky.social & thanks @seqcode.bsky.social for the against-stream efforts! 💪🏽

I believe AI tools have their advantages, but DeepSeek highlights significant limitations, particularly in how AI tools can be used to spread propaganda. We must recognize that human intelligence and rational thinking are still crucial and cannot be replaced by AI. #DeepSeekAI
