Fin al misterio de los trombos de la vacuna de AstraZeneca: la ciencia identifica por fin el fallo genético que los causa

¿Por qué la vacuna de AstraZeneca provocó efectos secundarios graves solo en un grupo minúsculo de personas? Tras años de incertidumbre, una investigación publicada en el New England Journal of Medicine revela la errata genética que transformó una protección en una amenaza.

Skin androgens regulate Staphylococcus aureus pathogenicity via quorum sensing Nature Microbiology, Published online: 27 February 2026; doi:10.1038/s41564-026-02261-2Testosterone produced by skin cells enhances Staphylococcus aureus pathogenicity by activating quorum sensing, and a stereoisomer of testosterone that blocks this interaction inhibits bacterial cytotoxicity towards human cells.

I’m happy to share our new paper! @krelllaboratory.bsky.social rdcu.be/eLhlE doi.org/10.1186/s130...

Trying to identify the signal molecule that activates your receptor? Read our review on the thermal shift assay in FEMS Microbiology Reviews. academic.oup.com/femsre/artic...

Las tortugas marinas son fieles a su playa (y eso condiciona el sexo de las crías) Las tortugas marinas son fieles al territorio donde desovan, y esto afecta al sexo de sus crías.

¿Sabías que la fidelidad de las tortugas marinas (y no precisamente a sus parejas) afecta al sexo de sus crías?

Today our PhD student @robertagenova.bsky.social is presenting her poster n 353 in poster area E at @femsmicro.org #FEMS2025 @miguelmatilla.bsky.social

Special thanks to our collaborators @jouline.bsky.social & @gavirius.bsky.social

How to identify the #signals that recognize a bacterial #receptor? Our work provides some tips to trackle with a main bottleneck in #microbiology. You'll find your answers in our poster 285 in area D. #FEMS2025 #microsky

Exciting 3rd day of #FEMS2025 . Today our post-doc @eli-monteagudo.bsky.social is presenting a poster n 285 at poster area D! And she is doing a flash talk at 1 pm at theatre 1 #microsky

Excited to be attending #FEMS2025 with @robertagenova.bsky.social @eli-monteagudo.bsky.social @krelllaboratory.bsky.social this week!
Looking forward to sharing our work on Ancylobacter cellulose synthesis and connecting with the microbiology community 🧫🧬

A fantastic first day of #FEMS2025 with @krelllaboratory.bsky.social @labo316.bsky.social @eli-monteagudo.bsky.social @sophiemartirani.bsky.social

What an inspiring first day at FEMS MICRO Milan! We heard from FEMS Pres. Antonio Ventosa at the Opening while former Pres. Hilary Lappin-Scott helped connect new attendees. Thanks to keynotes Profs. Carmen Buchrieser and Gian Rossolini for sharing their expertise. #FEMS2025

Rocío's PhD committee was formed by: Francisca Reyes #UPO #cabd, Carlos Medina @unisevilla.bsky.social y Elisabet Monteagudo @eezcsic.bsky.social
Great discussion! We wish Dr. Barroso the best!

#Neurotransmitters are signals that play roles in inter-kingdom #signaling. Our study identifies a #chemoreceptor in #Pseudomonas #aeruginosa responsible for triggering #chemotaxis to #dopamine, #serotonin, #epinephrine & #norepinephrine.
