😵💫: Private TV antenna3 hectically shot an interview 1.5h before their 3pm news, got a lot wrong (no we did not rejuvenate mice by ablating old stem cells, Irv Weissman did that) BUT they made us the good news of the day and it's somehow funny www.antena3.com/noticias/cie...
Científicos españoles descubren cómo envejece la sangre: un gran hallazgo para la lucha contra la leucemia y el envejecimiento
Un estudio desarrollado en Barcelona ha dado con la clave para entender cómo envejece la sangre. El hallazgo podría facilitar la detección temprana de enfermedades como la leucemia y abrir nuevas vías...

😬: SER Catalunya, most-listened radio around here, interviewed me at 8:40 (instead of 8:50)... they reached me in the elevator, put me live on air and started asking in Catalan. Had to guess what they meant and improvise. The good thing, I was awake after this 😅 (can't upload audio to bsky - 7/n)

Dès l’âge de 50 ans, les cellules de notre sang s’appauvrissent
Une équipe espagnole a retracé l’évolution des lignées de cellules du sang chez 13 personnes de 35 à 70 ans. A partir de la cinquantaine, le nombre de cellules souches capables d’engendrer des cellule...

„Blutbarcodes“ könnten Alterung verlangsamen
Auch das Blut altert: Ab 50 Jahren verringert sich die Vielfalt der Stammzellen, die Blut produzieren. Ein Forschungsteam hat nun ein „Barcodesystem“ entwickelt, das die verschiedenen Blutstammzellen ...

"A partir de los 50 casi todas las células madre se llaman Rodríguez" (Y eso es malo)
Un estudio liderado por dos centros de investigación de Barcelona ha descubierto que, a partir de esa edad, cada vez tenemos menos células madre sanguíneas y las que hay se replican cada vez con más e...

Out @nature.com: Clonal tracing with somatic epimutations
🧬 Single cell methylome encodes cell state & clonal identity
🔨 EPI-Clone reads out both (+mutations, +RNA) at scale
🩸 Clonal expansions of HSCs are universal from age 50, not driven by CH mutations

Clonal tracing with somatic epimutations reveals dynamics of blood ageing - Nature
The discovery that DNA methylation of different CpG sites can serve as digital barcodes of clonal identity led to the development of EPI-Clone, an algorithm that enables single-cell lineage tracing th...

What a year 😅 really really happy that both these projects worked out better that we could ever have planned, and the Barcelona scientific environment was super important for both of them!
