By far the majority of users of child sexual abuse networks (or child porn forums as they are sometimes called) on the dark web do not actively communicate there but download illegal material, therefore committing a criminal offence. But they often stay under the police and judiciary’s radar. PhD candidate…

Modelling supra-regional communities in the early 3rd Millennium BC

From filtering UV light in sun cream to preventing perspiration odour in socks and sterilising fridges and washing machines. The use of nanoparticles in products is increasing. But what is the impact of these miniscule particles on the environment?

Political scientist Luzia Helfer (Leiden University) empirically tested claims about media-politics relatiopns using unique data from experimental studies with elected politicians and political journalists in Switzerland and the Netherlands.
