The Food Citizens? team has contributed in the special issue of the ICA journal. The semi-scientific journal of the study association Itiwana of Leiden University's Institute of Cultural Anthropology.

The aim of this study is to further develop the Open Science Monitor, which started as a pilot study.

Fieldwork is an essential part of this research and of course this part of the project is also a joint effort by citizen scientists and professional archaeologists. Discover when fieldwork will take place and how you can participate.

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

The team consists of

Scientists are asking your help to find the origin of hundreds of thousands of galaxies that have been discovered by the largest radio telescope ever built: LOFAR. Where do these mysterious objects, which extend for thousands of light-years, come from? A new citizen science project called LOFAR Radio…
