Star Beasts: Interstellar Zeitgeber

Star Beasts subjects cyanobacteria (‘blue-green algae’) to artificial evolutionary pressures in order to modify their circadian rhythms to the day lengths of exoplanets in foreign solar systems. Each payload of a theoretically space-destined probe houses a continuous culture device, designed to travel into space before separating, and continuing towards their individual destinations. Cyanobacteria are a model organism for circadian rhythm research, and were fundamental in providing a breathable atmosphere on the early Earth.
The microorganisms are kept in a constant state of growth, change and eventual adaptation to their future environment. While the device does not directly modify the algae genome it changes the environmental conditions (such as day length) that forces the algae to genetically adapt. In this gallery instance, the periods of light and dark have been accelerated to synchronise with terrestrial human attention spans.
