‘Zo moeten we chemicaliën testen: in de buitenlucht!’
Blubberig, nat, drassig en modder: bij het horen van deze woorden denk je niet direct aan een laboratorium. Het Levend Lab in Leiden is dan ook niet zomaar een lab. Ecotoxicoloog Martina Vijver en haar team onderzoeken er het effect van onder andere bestrijdingsmiddelen op het waterleven. Dorien Rozing…

A Manifesto for Investigating the Impacts of Object Flows on Past Societies: Objectscapes
World history is often framed in terms of flows of people and migration: humans coming ‘out of Africa’, the spread of farmers in the Holocene, Phoenician and Greek diasporas over the ancient Mediterranean, the colonization of the world by Europeans from the 16th century onwards. Together with his Exeter…
