Deep Time - 40 Days of Darkness – DW – 07/04/2025
A scientific adventure aims to find out.
One day in March, seven women and seven men, led by explorer and researcher Christian Clot, enter the Lombrives cave in the French Pyrenees. They intend to spend 40 days there, without daylight - and with no other means of marking time.
They begin the "Deep Time' experiment. It is a group experience with an interdisciplinary scientific approach that goes far beyond mere : The aim is to explore people's ability to adapt to extreme situations.
The participants set up their base camp deep in the cave. They have to organize life in the camp and learn to function as a group under extreme conditions. The lack of daylight, cold and fatigue affect the rhythm of each individual in different ways.
The deeptimers are equipped with sensors and high-tech devices to collect scientific data -- before, during and after their stay in the cave.
This data is analyzed by experts in the fields of cognitive science, chronobiology, sociology, physiology, psychology, ethnology, social organization and genetics.
The scientists report on their initial findings a few months after the end of the experiment. In the long term, their interdisciplinary analyses will contribute to a better understanding of the mechanisms and limits of human adaptation.

Deep Time - 40 Days of Darkness – DW – 07/04/2025
14 volunteers live underground for 40 days. With no way to mark time, this is an extreme experiment. How do people adapt to these conditions? How do the body and brain react to the loss of a sense of time? A scientific adventure aims to find out.

Can't Feel Nothing - How the Internet Warps Our Emotions – DW – 06/27/2025
Is the internet making us emotionally numb? Online trolls and influencers expertly manipulate people's feelings, leading many to disconnect from their emotions. Scientists explain how the internet influences what we feel — and whether we feel at all. A man lies in bed, illuminated by the blue-white light of his smartphone screen. As he scrolls through endless social media feeds, he sees adorable pets, outraged opinion pieces, and haunting images from conflict zones - but he feels absolutely nothing. With curiosity and humor, director David Borenstein travels to Europe, Asia, the U.S., and Russia to investigate how bad things really are. Who is pulling the strings when the internet makes us angry, sad, horny or just plain indifferent? Is there any way to reclaim our emotions? Borenstein portrays a range of perspectives, including an American internet troll, a burnt-out star from the Asian influencer industry, a Russian state propagandist, and an online dominatrix. Scientific research into human emotions sheds light on how our emotional responses are being manipulated. The result is an alarming diagnosis of our digital era — paired with a bold attempt to search for solutions.
