BioClock contributes to international dialogue on the Night as a Habitat

July 11, 2025

Night is more than just a moment on the clock – it is a rich and diverse habitat we still know surprisingly little about. But what does ‘the night’ mean for our modern cities?

For the latest Roundtable by the international platform The Nature of Cities (TNOC), researchers, designers, and policymakers from around the world shared their perspectives on the night. Their goal: to shed light on the lives that unfold after sunset in cities across the globe. Mara Cotterink also contributed on behalf of the BioClock Consortium.

In her piece “The Unbearable Brightness of the Dark”, Mara highlights the importance of natural darkness for both humans and nature. It was a valuable opportunity to raise awareness about the biological clock and the negative effects of light pollution among a broad international audience.
