Cosmonauts Pyotr Dubrov and Anna Kikina practiced replacing a thermal control panel for the ISS underwater 👨🏻‍🚀 The cosmonauts trained in the hydrolab. They are preparing for work outside the station. The thermal control panel is stored in a pressurized cylindrical container equipped with handrails. The cosmonauts carry the load in turns, passing the container to one another. In space, the crew will be assisted by the ERA robotic arm.

In 1901, divers pulled a lump of corroded bronze out of a two thousand year old shipwreck. It took the next century to understand what it was, and the answer broke the timeline of human history. It's called the Antikythera Mechanism, and it is the oldest known computer on earth. It was built by the ancient Greeks, around 100 BC, and it should not exist. Nothing else of its sophistication would appear anywhere in the world for more than a thousand years after it... It was found by sponge divers off the Greek island of Antikythera, in the wreck of a trading ship that had sunk in the first century BC, surrounded by bronze statues and pottery. The corroded fragments looked like nothing at first, and sat largely ignored in a museum in Athens. Only over the following decades, and especially with modern X-ray and CT scanning in our own century, did researchers finally see inside it. What they found was a machine. Behind its bronze face was a system of at least thirty interlocking precision gears, cut and arranged with a sophistication that would not be matched until the geared astronomical clocks of medieval Europe, well over a thousand years later. It was, in the words of the team that studied it, a mechanical computer that worked by turning astronomical theory into bronze... And it did extraordinary things. You turned a hand crank on the side, and the mechanism calculated the positions of the sun, the moon, and the five planets the Greeks knew. It tracked the phases of the moon. It predicted solar and lunar eclipses years in advance. It even displayed the four-year cycle of the ancient Olympic Games. A person standing in the ancient world could set this device to a date and watch the heavens be calculated in front of them, by gears, by hand. Roughly a third of the original survives, in 82 corroded fragments. We still do not know who designed it, or how a civilization without anything resembling industrial machinery achieved this level of precision engineering. What is certain is that it was not a one-off accident. A device this refined implies a tradition behind it, generations of knowledge and earlier attempts that have been lost completely. The Antikythera Mechanism is proof of how much the ancient world knew, and how much of what human beings have achieved has simply vanished without a trace, leaving us to stumble on a single piece of it at the bottom of the sea...

In 2023, researchers in a deep-sea submersible west of Australia came across several whale skeletons 2400 meters deeper than had ever been described. As the expedition continued, the scientists found an unprecedented abundance of skeletons—the biggest, deepest, and oldest collection ever seen on the sea floor.

Un pilote de l'aéronavale se brise les deux bras dans un accident de voiture. Les chirurgiens veulent amputer. Il refuse. L'ordonnance de rééducation tient en un mot : nager. Ce mot va changer notre regard sur les océans. Né le 11 juin 1910 à Saint-André-de-Cubzac, en Gironde, ce fils d'avocat entre à l'École navale en 1930. Il rêve de voler. L'accident brise le rêve, et l'envoie nager chaque jour en Méditerranée. En 1936, à Toulon, un camarade officier, Philippe Tailliez, lui prête des lunettes sous-marines. Il met la tête sous l'eau, découvre les fonds du Mourillon. Sa décision est prise : sa vie se jouera là-dessous. Problème : on ne tient sous l'eau que le temps d'un souffle. Alors en 1943, avec l'ingénieur Émile Gagnan, il met au point le scaphandre autonome moderne. L'humanité peut enfin respirer sous la mer. Suivront un navire, la Calypso. Un film, Le Monde du silence, Palme d'or à Cannes en 1956. Et des décennies d'émissions qui ont fait entrer les fonds marins dans les salons de famille. Un bonnet rouge sur la tête, le commandant Cousteau a ouvert au regard des hommes les deux tiers de la planète. Vous regardiez ses documentaires ?

A Norwegian neuroscientist spent 20 years proving that the act of writing by hand changes the human brain in ways typing physically cannot, and almost nobody outside her field has read the paper. Her name is Audrey van der Meer. She runs a brain research lab in Trondheim, and the paper that closed the argument was published in 2024 in a journal called Frontiers in Psychology. The finding is brutal enough that it should have changed every classroom on Earth. The experiment was simple. She recruited 36 university students and put each one in a cap with 256 sensors pressed against their scalp to record brain activity. Words flashed on a screen one at a time. Sometimes the students wrote the word by hand on a touchscreen using a digital pen, and sometimes they typed the same word on a keyboard. Every neural response was recorded for the full five seconds the word stayed on screen. Then her team looked at the part of the data most researchers had ignored for years, which is how different parts of the brain were communicating with each other during the task. When the students wrote by hand, the brain lit up everywhere at once. The regions responsible for memory, sensory integration, and the encoding of new information were all firing together in a coordinated pattern that spread across the entire cortex. The whole network was awake and connected. When the same students typed the same word, that pattern collapsed almost completely. Most of the brain went quiet, and the connections between regions that had been alive seconds earlier were nowhere to be found on the EEG. Same word, same brain, same person, and two completely different neurological events. The reason turned out to be something nobody had really paid attention to before her work. Writing by hand is not one motion but a sequence of thousands of tiny micro-movements coordinated with your eyes in real time, where each letter is a different shape that requires the brain to solve a slightly different spatial problem. Your fingers, wrist, vision, and the parts of your brain that track position in space are all working together to produce one letter, then the next, then the next. Typing throws all of that away. Every key on a keyboard requires the exact same finger motion regardless of which letter you are pressing, which means the brain has almost nothing to integrate and almost no problem to solve. Van der Meer said it plainly in her interviews. Pressing the same key with the same finger over and over does not stimulate the brain in any meaningful way, and she pointed out something that should scare every parent who handed their kid an iPad. Children who learn to read and write on tablets often cannot tell letters like b and d apart, because they have never physically felt with their bodies what it takes to actually produce those letters on a page. A decade before her, two researchers at Princeton ran the same fight using a completely different method and ended up at the same answer. Pam Mueller and Daniel Oppenheimer tested 327 students across three experiments, where half took notes on laptops with the internet disabled and half took notes by hand, before testing everyone on what they actually understood from the lectures they had watched. The handwriting group won by a wide margin on every question that required real understanding rather than surface recall. The reason was hiding in the transcripts of what the two groups had actually written down. The laptop students typed almost word for word, capturing more total content but processing almost none of it as they went, while the handwriting students physically could not write fast enough to transcribe a lecture in real time, which forced them to listen carefully, decide what actually mattered, and put it in their own words on the page. That single act of choosing what to keep was the learning itself, and the keyboard had quietly skipped the choosing and skipped the learning along with it. Two studies. Two countries. Same answer. Handwriting makes the brain work. Typing lets it coast. Every note you have ever typed instead of written went into your brain through a thinner pipe. Every meeting, every book highlight, every idea you captured on your phone instead of on paper was processed at half depth. You did not forget those things because your memory is bad. You forgot them because typing never woke the part of the brain that would have made them stick. The fix is the thing your grandmother already knew. Pick up a pen. Write the thing down. The slower road is the faster one.
