DNA from Napoleon’s 1812 army identifies the pathogens likely responsible for the army’s demise during their Russian retreat. www.cell.com/current-biol... Nicolás Rascovan & colleagues @currentbiology.bsky.social

A couple of bugs in the system for the troops it turns out. French teams led by @pasteur.fr / @nrascovan.bsky.social have analysed centuries-old teeth to find out what ailed Napoleon's troops during their doomed retreat www.dw.com/en/napoleons...

@isba11.bsky.social Super happy and proud for @marialopopolo.bsky.social and @avanzich.bsky.social who got the prize to the best paper at #ISBA11 in Turin. Thanks to the jury for this honor!

Les Européens ont-ils apporté la lèpre en Amérique ? En explorant cette question, des chercheurs ont dévoilé l'histoire complexe des bactéries responsables de cette maladie. Un beau travail de @nrascovan.bsky.social et ses collègues. www.pourlascience.fr/sd/microbiol...

🌎🧬 Leprosy was already endemic in the Americas for 1,000+ years BEFORE Europeans arrived. Scientists analyzed DNA from ~800 samples & found Mycobacterium lepromatosis infecting Indigenous populations centuries before colonization. #Leprosy @marialopopolo.bsky.social @nrascovan.bsky.social

Excited to have been a small part of this amazing project lead by @marialopopolo.bsky.social and headed by @nrascovan.bsky.social My part was #ancientDNA labwork for one ancestor that had M. lepromatosis - a form of leprosy present in the US before European contact. Out in #Science -link in thread

Un diente reescribe la historia americana Una gran investigación de @nrascovan.bsky.social @marialopopolo.bsky.social @avanzich.bsky.social publicada hoy en @science.org Lo cuento en @agenciasinc.es www.agenciasinc.es/Reportajes/U...

Big news in #GlobalHealthHistory today. A species of bacterium that causes leprosy, discovered in 2008 in modern patients, has been proven to have been present in the Americas well before European arrival. More details in 🧵 below: www.science.org/content/arti... #GlobalMiddleAges #histmed #aDNA 🧪
