Will a child survive? Older siblings have a powerful influence
Swiss birth data from 1750 to 1870 reveal that girls who had lots of older brothers close to their own age were less likely to survive than were those who did not.

Age- and sex-dependent associations between the number of older siblings and early-life survival in pre-industrial humans | Proceedings of the Royal Society B: Biological Sciences
Siblings are an important part of an individual’s early-life environment and may therefore play an important role in shaping an individual’s survival. The quantification of sibling effects on survival is challenging, however, especially in long-lived ...

Cool data from @markspa.bsky.social showing C19th disease patterns (e.g. dysentery) can predict spatial clustering if modern disease loads (e.g. inflammatory bowel disease). Exciting to see what more comes out of this.

Last week it was finally time for the AURA symposium! A symposium we organized for Researchers in Biology, Geology and Geography. Had such a great time presenting my initial work on spatial patterns of historical death causes and working alongside the rest of the team to make it a big succes.

Super proud of our PhD @markspa.bsky.social who was practicing his talk for the Aura symposium next week in Turku.
Mark will tell how studying former diseases spread can tell us about future epidemics. #humanhealth #historicaldata #humanresearch

Had a great time attending the Profi7 Computational Seminar Day! Loved seeing some of my initial work on this huge screen.
