Sympa

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.

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.
