Uncover the secrets of Renaissance DIY science! A new study reveals how people in the 16th century were more like DIY scientists than Macbeth's witches when it came to concocting home remedies. Multispectral imaging, proteomics, and historical texts are shedding light on the medical manuals of the time, showing a thriving DIY medical marketplace. But here's where it gets controversial... The research team, led by Stefan Hanss, an early modern historian, focused on two German medical manuals from 1531. They analyzed trace proteins from fingerprints left by readers, revealing fascinating insights into the experimentation and tweaking of recipes. And this is the part most people miss... The study not only uncovered popular ingredients and remedies, but also showed how people's bodies responded to them. From collagen peptides from hippopotamus teeth to antimicrobial proteins, the findings offer a unique window into the scientific practices and knowledge of the Renaissance era. So, what do you think?
