The immune systems paradox

Some widespread prokaryotic immune systems are absent in eukaryotes, whereas relatively rare ones became central to eukaryotic innate immunity

@audeber.bsky.social & E. Koonin hypothesize the answer is #HGT

Peste porcina:

Los análisis genéticos sugieren que el virus no salió del laboratorio de la Generalitat que estaba a cientos de metros

(según una primera comparativa "no concluyente")

On January 1st, I promised to document 52 ancestors with AI assistance.
Eleven months later, the project finally started.
Now it's a December sprint: 62 ancestors, 31 days, GPS methodology, mistakes corrected in public.
Is "vibe genealogy" a compliment or a warning? Maybe both.

La Generalitat no ve indicios de que el brote de peste porcina saliera del laboratorio de Bellaterra

"Solo la comparación exhaustiva del ADN de los virus de dentro y de fuera de las instalaciones aclarará el origen del patógeno"

My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: ‘Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’
This is so disgusting.

"we must rethink the brute force approaches that attempt (futilely) to fight resistance (...). Instead, we should pursue complementary strategies that mitigate selection of antibiotic resistance"
