LOMBRIVES CAVE, France (AP) — After 40 days in voluntary isolation, 15 people participating in a scientific experiment have emerged from a vast cave in southwestern France. Eight men and seven women lived in the dark, damp depths of the Lombrives cave in the Pyrenees to help researchers understand how people adapt to drastic changes in living conditions and environments. They had no clocks, no sunlight and no contact with the world above. With big smiles on their pale faces, the 15 participants in the Deep Time project exited the cave exited the Lombrives cave to a round of applause and basked in the light of day while wearing special glasses to protect their darkness-adapted eyes.
