What awaits us after dark? This week the Forum discusses the hazards and the creative possibilities of the night.

Do we manipulate the darkness, or does it manipulate us?

Oxford Professor of Circadian Neuroscience, Russell Foster, explains his research which shows how the blue-tinged sky of dusk is a trigger that tells our bodies it's time to prepare for bed.

And why it would be good for us to go back to rising with the dawn and going to bed at sundown.

Rut Blees Luxemburg finds surprising richness of night-time colours in her photographs, and historian Craig Koslofsky shows how early modern Europeans first colonised the night by introducing street lighting.
