Demos is pleased to invite you to the third of the Demos Science Cafés. These monthly events are an opportunity for scientists, policymakers, journalists, social scientists and anyone else to draw out the policy implications of current scientific issues.

At each café, we'll hear from a visiting speaker about their work. The discussion will then be open to our guests.

On 20th July, we are pleased to welcome Professor Simon Wesseley, of the Institute of Psychiatry, who will be talking to us about contested illnesses such as Gulf War Syndrome and Chronic Fatigue.

The event is free. If you'd like to come along, email science@demos.co.uk
