Imaginez passer 100 jours sous l'eau et en ressortir en vous sentant plus jeune ! C'est exactement ce qui est arrivé à un homme qui s'est porté volontaire pour une expérience scientifique audacieuse. Vivant dans un habitat sous-marin spécialement conçu, il a respiré un air légèrement différent et a vécu sous une pression inférieure à celle que nous connaissons sur terre. Le résultat ? Son âge biologique a effectivement fait marche arrière—son corps montrait des signes de rajeunissement par rapport au début de l'expérience. L'expérience n'était pas seulement un moment de science-fiction fascinant ; elle pourrait mener à des découvertes révolutionnaires dans le domaine de la santé. Animation créée par Sympa.

00:00What is the strangest task you have accomplished in the context of your work?
00:05Was it to print hundreds of pages of uninteresting reports, or to untangle the Christmas lights?
00:11Know that a scientist spent 100 days immersed under the Atlantic.
00:15Dr. Joseph D. Tree, nicknamed Dr. Deep Sea, lived underwater as part of the Neptune 100 project.
00:23This program aimed to study in the long term the effects of compression on the human body,
00:28both physically and mentally.
00:31Dr. Deep Sea, biomedical engineer and lecturer at the University of South Florida,
00:36dived into this underwater experience to determine whether increased pressure could extend human life
00:42and limit aging-related health problems.
00:45From the start of his mission, Dr. Deep Sea actively shared his daily life on social media.
00:51He also stressed that another essential goal was to inspire researchers of all generations
00:57to explore underwater life.
01:00After 74 days of mission, he broke the world record for the longest period spent in a fixed underwater habitat.
01:08However, instead of going back to the surface after this stage, he continued until he reached the 100 days planned.
01:15These 14 weeks will have been well filled.
01:18It is the least we can say.
01:20Collecting data, scientific collaboration, teaching remotely from a biomedical engineering course at his university,
01:26and exchanges with thousands of students from 15 countries.
01:29Once the mission was completed, Dr. Deep Sea was warmly welcomed by his family, his friends, the media
01:36and many admirers who followed his project.
01:39Today, 55 years old, he claims that this underwater experience gave him the impression of being 10 years younger.
01:46The doctors who examined him and the first analyzes confirm some rejuvenation effects.
01:51His sleep and metabolism have improved.
01:55He also noticed that his waist had shrunk by a good centimeter.
01:59With 300 more days naked, he could theoretically lose 30 centimeters.
02:03Or maybe not.
02:05If you want to experience a lighter version of what Dr. Deep Sea has experienced, two options are available to you.
02:11The first consists of hyperbaric oxygenotherapy.
02:14You enter a specialized room where the air pressure is higher than normal,
02:18allowing a greater amount of oxygen to penetrate your lungs.
02:22This method favors healing processes, but an excess of oxygen can be harmful, which requires strict regulations.
02:30You can also stay at Jules Undersea Lodge, the very place where Dr. Deep Sea lived,
02:35named after Jules Verne, the author of 20,000 places under the sea.
02:40It is a two-bedroom apartment located 9 meters below the surface of a Key Largo lagoon in Florida.
02:46Rest assured, this unusual accommodation is not likely to move away.
02:49It is solidly anchored to the seabed by special structures.
02:53Three windows offer an impregnable view of the ocean and its abundant marine fauna.
02:58The hotel also has an oxygen, water and electricity control center,
03:03an air conditioning system to ensure optimal comfort,
03:07as well as a chef diving in to prepare meals on request.
03:10However, you can't just dive head first to see if there is a free room.
03:16Each client must comply with administrative formalities.
03:19In addition, it is necessary to carry specific equipment that you should leave in a dedicated area before taking advantage of your apartments.
03:26As for Dr. Deep Sea, he does not intend to interrupt his research on how humans can survive in isolated environments.
03:34He plans to take part in a flight on board a modified aircraft that allows him to experience several weightlessness experiences.
03:40This type of adventure, little adapted to the sensitive heart,
03:43represents a key step towards his goal of becoming a civilian astronaut and traveling in space by 2026.
03:50Dr. Deep Sea is not the first scientist to isolate himself in an unusual setting to conduct research.
03:56Italian sociologist Maurizio Montalbini spent two years and eight months in caves
04:01to study the ability of the mind and the human body to adapt to total isolation.
04:06He began his experiments in the 1980s and, at the end of 1986,
04:12he settled in a cave in the Apennines, near Ancona in Italy, the Frasassi cave.
04:17He only resurfaced 210 days later,
04:20becoming the holder of the world record for the longest complete isolation stay at that time.
04:26To survive, Montalbini was fed with a hypercaloric regime composed of powder and compressed,
04:31similar to that used by astronauts on space missions.
04:35Researchers followed his state of health in real time
04:39thanks to specific tools installed outside the cave.
04:42Later, Maurizio broke his own record and explained that achieving such an achievement
04:47required mastering one's loneliness rather than fighting it.
04:51His research, conducted in collaboration with NASA and several universities around the world,
04:57has shown that isolation affects the perception of time and sleep cycles.
05:01An interior architect from Ancona, inspired by his experiments,
05:05decided to participate in a similar study in 1989.
05:10Stefania Follini spent four months in an underground room located 9 meters deep
05:15in the Lost Cave of New Mexico.
05:18The goal of the experiment was to study circadian rhythms,
05:22these 24-hour cycles that register the internal clock of our body.
05:26Devoid of natural clues to locate time,
05:29she quickly began to stay awake for more than 20 hours and sleep 10 hours in a row.
05:34Thus, her biological clock adjusted to a 48-hour cycle.
05:39She played the guitar, used a computer,
05:43and interacted with two mice named Giuseppe and Nicoletta, frogs and otters.
05:48To personalize her space, she made cardboard decorations
05:53and practiced judo to maintain her strength and flexibility.
05:57At the end of the experiment, the scientists who welcomed her asked her to guess the date.
06:02She thought it was mid-March, when she was actually leaving the cave on May 22.
06:08Stefania had lost the notion of time, as well as 8 kg,
06:12due to her new rhythm and a diet mainly composed of beans and rice.
06:17She also suffered from a vitamin D deficiency.
06:21You know that feeling when your parents insist relentlessly on an idea
06:25and you dream of proving them wrong.
06:28This is what prompted Dr. Donald Unger to undertake a scientific experiment,
06:32at least singular.
06:34For more than 50 years, he cracked the joints of his left hand twice a day.
06:39Contrary to what his mother had predicted, he had no serious health problems.
06:44Although this experiment alone is not enough to confirm or refute this widespread belief,
06:49other studies have come to similar conclusions.
06:52Regine Gris, a Canadian biologist from British Columbia,
06:56chose to take the famous adage at the foot of the letter.
07:00Au lit marin, la puce a faim.
07:02Et a volontairement laissé des punaises des lits la piquer.
07:05Environ 180 000 fois.
07:07Tout cela pour la science.
07:09Son objectif était d'analyser et d'identifier les composés les plus efficaces
07:13pour attirer et piéger les punaises de lits.
07:15Ces intrus notoires dont l'élimination peut s'avérer coûteuse et complexe.
07:19La biologiste, en collaboration avec son équipe,
07:22a voulu tester si des pièges apathés avec des phéromones
07:25pourraient attirer ces parasites,
07:27afin de détecter leur rassemblement avant qu'ils ne prolifèrent.
07:31Cependant, un élément crucial manquait à leur recherche.
07:34Le composé utilisé par les punaises de lits,
07:37pour identifier un habitat comme sûr et propice à leur installation.
07:41C'est ainsi que Gris s'est transformée en appât vivant pour ses nuisibles.
07:45Avec son équipe, elle a réussi à isoler le composé recherché,
07:48l'histamine, une substance que les humains produisent lors des réponses immunitaires.
07:53Les chercheurs estiment que cette découverte
07:55pourrait permettre de fabriquer des pièges chimiques abordables
07:58pour lutter contre ces parasites.
08:00Le Dr Kevin Warwick, ancien professeur de cybernétique à l'université de Reading, au Royaume-Uni,
08:06a marqué l'histoire en devenant le premier véritable cyborg.
08:09Il a relié son propre système nerveux à un ordinateur
08:12pour explorer les possibilités qu'offre la technologie dans le domaine de la santé.
08:16En implantant un dispositif dans son bras gauche,
08:18il a pu transmettre ses signaux neuronaux à une main robotique et la contrôler.
08:22Selon le scientifique, les implants représentent une solution idéale
08:25pour les personnes souffrant de troubles neurologiques,
08:28leur permettant de manipuler des objets simplement par la pensée.
08:31Mais cette technologie ne se limite pas aux traitements médicaux.
08:35En connectant le cerveau humain à un ordinateur
08:38ou à un système d'intelligence artificielle,
08:40elle pourrait révéler un immense potentiel pour l'humanité tout entière.
