Cell Worlds is a journey to the heart of the microscopic living world. It is an unprecedented discovery of a hidden biodiversity: our cells. A journey of introspection and emotion to discover unsuspected microscopic forms, colors and behaviors. Migrations, hunts, symbioses and even communications, who would have thought that the infinitely small was so grandiose? The exploration of these worlds is accompanied by a poetic narration, supported by an original music specially composed for the occasion. Cell Worlds offers a synergistic alliance of images, sound and narration, which gives way to real moments of contemplation of scientific research. It is the first showcase of the most beautiful microscopy images from 26 research teams around the world.
