🔎 Què passa amb el nom #Mercè?

📉 Cada cop és menys freqüent entre els nadons a #Barcelona.

🗣️ Francesc Calafell, investigador de l’ @ibe-barcelona.bsky.social i professor de la @upf.edu, ho explica al @ara.cat .

👉
Mercè, el nom de iaia que ja no es posa
La majoria de Mercès actuals van néixer abans del 1975 i no és un nom popular entre els nadons que neixen ara

Excited to share our new preprint🙌
It's the first human WGS study in Sudan. We uncover one of the strongest selection signals to date, pointing to post-admixture adaptation to malaria in Copts. Huge thanks to all co-authors. @aidaandres.bsky.social @jgarcia-cal.bsky.social @ebosch1972.bsky.social

Where Babies Come From

xkcd.com/3127/
Comic. Various Experts Answer the Question “Where do babies come from?” Geneticist: Recent admixture event, roughly 0.001 kya. Astronomer: Low-impulse ejection from a parent body. Software engineer: Off-by-one error in the population calculations. Geologist: The area was originally a uniform plane, but the non-baby parts eroded at higher rates. Meteorologist: Moist ground-level turbulent mixing.
