Many traces of the city's slavery history can be found in Leiden but the public isn't always aware of them. The initiators of 'Mapping Slavery in Leiden' want to change this with guided tours and street markers. Representatives of the University and other Leiden institutions will be giving the first…

Cutting down global emissions of greenhouse gases to combat global warming won’t do the trick alone: we also need negative-emissions technology that can capture carbon dioxide directly out of the air. In the prestigious journal Global Environmental Change, PhD candidate Oscar Rueda and colleagues shed…

Rapid developments in DNA techniques allow researchers to find out more and more about human genetics. An international group of scientists has drawn up five ethical guidelines to ensure that this DNA research is better regulated. Leiden archaeologist Marie Soressi – one of the signatories - explains…
