Schwarzenegger continues training every day at 78 years old and the fascinating thing is that he is right

by

At 78 years old, the seven-time Mr. Olympia and the most famous cyborg in the history of cinema continues to faithfully attend his appointment at the gym, as Schwarzenegger acknowledges in an entry on his personal blogwhere he explains that even on days when he has less energy he goes to exercise, something that sums up pretty well with the phrase: “No matter the pain, no matter the weight, every day I achieve a victory.” It’s a reality. His mentality, forged in the golden age of bodybuilding, might seem like the eccentricity of a Hollywood star who refuses to age. However, behind Schwarzenegger’s weights and pulley machines lies one of the most robust physiological truths of modern medicine: strength training starting at age 70 and 80 is not an aesthetic whim, It is a medical necessity. Falling into the stereotype that sport is for young people who want to show off having a good body on the beach is real nonsense, because playing sport literally becomes the next prescription for all the benefits it entails. And logically being more or less old here does not at all condition entry to a gym, as science recognizes us. Inactivity weighs more. To reach old age in better health, you don’t have to invest a lot of money in super expensive supplements or creams to keep your skin firm. And there is a widespread belief that the loss of functional capacity and weakness are inevitable consequences of getting older, but here the National Institute on Aging from the United States is blunt about it: in the vast majority of cases, physical inactivity weighs much more than biological age itself in this deterioration. One of the great silent enemies of middle age is sarcopenia, which is the gradual loss of muscle mass and strength, and which literally correlates with both quality and life expectancy. And to correct it, the only treatment we have at hand is to do strength training adapted to each person profile, directly improving our ability to perform such everyday tasks as getting up from a chair, walking to the supermarket or carrying shopping bags. It’s never too late. Another of the great myths that we also have on the table is that you are too old to start exercising, but here the scientific literature reminds us that it is false, since starting late is still (very much) worth it. Here, a study that grouped 121 randomized trials with 6,700 participants showed that progressive strength training improves muscle strength and functional capacity in older people. This resulted in an improvement in autonomy by significantly improving their walking speed and their ability to climb stairs autonomously. Besides this, a recent systematic review of the Polytechnic University of Madrid on training in older people reported that traditional strength training can achieve improvements in knee extension strength of up to 46%. That percentage, in clinical practice, is the difference between needing a walker or walking on your own. Beyond the muscle. Strength work is also important for bone formation and combating osteoporosis by reducing several cardiometabolic risk factors. Besides, the Heart Foundation points out that strength work, added to balance and mobility training, is vital to protect against falls. It is not something minor, since in people over 70 years of age a fall is not an accident, but rather it is one of the most serious clinical problems that can drastically reduce life expectancy. Added to all this is that exercise has been shown to help regulate sleep, improve mood (reducing stress and anxiety) and even protect cognitive function. Adapted. There is no need to try to emulate Schwarzenegger’s youth records to obtain these benefits, but current medical guidelines agree on a minimum effective dose that is very affordable for almost everyone. In this case, for a person over 70 years old, a reasonable guideline supported by evidence is to train strength at least 2 days per week. But here you should always adapt the exercise to each person and start with a gentle exercise and gradually increase it. Although you don’t just have to be with the dumbbell in your hand, it should be combined with balance routines, joint mobility and some aerobic work.

from useless grass to the birth of fascinating life

by

In 1995, several scientists who They studied ancient craters left by World War II bombs in Europe discovered something unexpected: Decades after the war, many of those holes filled with water had become small natural refuges where amphibians, insects and birds that barely found safe spaces elsewhere in the landscape thrived. A hole in the ground that ended up changing an ecosystem. In many gardens, the corners where water accumulates after rain are often seen as a problem: uncomfortable mud, grass that is impossible to maintain or small puddles that sooner or later someone ends up draining. However, in the midst of the global crisis that amphibians go throughthose spaces are beginning to look different. In fact, they had a few days ago in Economics a story that occurred on a small plot of land near a fish farm that demonstrates the extent to which something seemingly insignificant can be transformed into an unexpected refuge for wildlife. The idea of ​​building a pond that would disappear. Apparently, the owner decided to dig a shallow depression, barely about 60 centimetersright in an area where thaw and rain already accumulated water naturally before ending up being lost in a ditch. The key to the project was precisely that it was not a permanent pond. It was designed as a “vernal pool”a seasonal pond intended to fill during winter and spring and gradually dry out in summer. This detail is essential because it prevents the presence of fish, one of the greatest dangers for eggs and tadpoles. Shallow water also warms faster and accelerates the development of larvae before the pond disappears, something essential for species that live against the clock. The frogs are coming. The most surprising it was the speed with which nature responded. Just weeks after filling with rain and meltwater, five gelatinous masses of wood frog eggs appeared attached to submerged branches near the shore. Although at first glance they seemed like small isolated groups, each of these masses could contain hundreds or even thousands of eggs. The pond still had very little vegetation and just a few logs, leaves and accumulated mud, but that was enough for the amphibians to immediately identify the place as a safe breeding point. A corner of grass with no apparent use had just become a natural nursery for one of the most endangered species on the planet. The mud also attracted other species. The frogs weren’t the only ones to take advantage of the change. Part of the shore was deliberately left bare and muddy to favor swallows, which need wet mud to build and reinforce their nests. The previous year several had inspected the dwelling without remaining definitively, possibly due to lack of suitable materials nearby. Now the garden offered just what they needed. Plus: to that was added a bat box placed next to the pond, creating a small ecosystem where insects, amphibians, birds and mammals began to interact around the water. What was once a uniform surface of grass and pine trees began to transform into a much more vivid and diverse mosaic. The silent amphibian crisis. As they remembered in the middleall this occurs at a particularly delicate time for amphibians. Near of 40% of the species on the planet are threatened with extinction due to habitat loss, disease and climate change that alter the rains and dry out entire breeding areas. In this context, small temporary ponds like this one are beginning to acquire enormous importance because they offer just the conditions that many species need to survive. The problem is that, being small and seasonal spaces, there are often outside the protections traditional legal systems and go unnoticed in the face of much larger wetlands. The idea that is changing many gardens. He experimentFurthermore, it leaves a powerful conclusion: a simple shallow hole can become a useful piece within a much larger network of refuges for amphibians and other species. Obviously, a single pond will not change on its own the global crisis of biodiversity, but thousands of small interventions distributed among gardens, farms, parks or schools can begin to create safe corridors for increasingly pressured animals. And perhaps the most striking thing is that a good part of these spaces already exist: they are precisely those corners of the garden where every spring a puddle appears that someone usually tries to eliminate as soon as possible.

the Chernobyl nuclear disaster, illustrated in fascinating cartographies of the disaster

by

On April 26, 1986, reactor number 4 of the Chernobyl nuclear power plant, in the former Ukrainian Soviet Socialist Republic, exploded during a low-power safety test. The accident released an estimated amount of radioactive material of 400 times greater than that of the Hiroshima atomic bomb, according to the International Atomic Energy Agency. The RBMK-1000 reactor involved had no containment structure, so radioisotopes such as iodine-131, cesium-137 or strontium-90 were freely dispersed into the atmosphere for ten days in a row, until they extinguished the graphite fire on May 5. The management of the accident could clearly be improved: the authorities ordered the evacuation of the nearby city of Pripyat 36 hours later and the world found out when Sweden detected radiation at its Forsmark plant on April 28. Ten years later, independent Ukraine published the Atlas of the Chernobyl Exclusion Zonea set of large-format graphic resources prepared by the state cartographic agency. As explains data journalist Attila Bátorfywas the first serious attempt to map the radioactive impact of the disaster on the soil, air and ecosystems and a large number of scientific professionals from entities such as the Ukrainian Academy of Sciences or other research institutes dependent on the Ministry of Ukraine for the Protection of the Population from the Consequences of the Chernobyl Nuclear Power Plant Accident participated in its preparation. Now it is available to anyone thanks to the digitized version available on Ecogisstorage. The atlas contains different cartographic blocks. One of the first and essential to understand evolution are the weather maps of europe the days during the active phase of the accident and show what the atmospheric situation was like afterwards, with isobars, atmospheric fronts or wind direction for each day. This is the basis of everything because without reconstructing how the air circulated those subsequent days it is not possible to interpret other pollution maps. The radioactive cloud followed erratic trajectories conditioned by the weather fronts, which explains why countries such as Sweden, Poland or Austria received significant deposits while closer areas were relatively less affected. Daily synoptic weather maps of Europe during the active phase of the Chernobyl accident To analyze the meteorological influence on dispersion in Ukraine, different graph formats are used, such as bars, wind speed and direction diagrams, or this one that goes under these lines: the radiological wind rose, which shows the amount of material released in each direction of the mean wind in the atmospheric boundary layer. Each line on the diagram represents the mean wind direction in the atmospheric boundary layer at a given time, with its date noted, the length indicating the magnitude of the radioactivity released. At first glance something can be seen: The dispersion was neither uniform nor radial.but tremendously asymmetrical. Thus, some fronts dragged pollution northwestward, towards Belarus and Scandinavia, while others diverted it to the south and west of Ukraine. Vector diagram of radioactivity emissions (in Bq) constructed for the average wind direction in the atmospheric boundary layer. The effects of the Chernobyl disaster, on maps Under these lines This is the most important map by far: that of Cesium – 137. Why is it important? Because due to its characteristics, Cs-137 is the radiological tracer par excellence, which allows directly showing the permanent chemical trace of the accident on the territory. Retrospective estimation map of soil contamination with cesium-137. At a scale of 1:200,000, it shows the deposition density of Cesium – 137 in the soil on May 10, 1986, reconstructed in retrospect. The pollution isolines draw a tremendously asymmetrical patch, with an absolute maximum concentrated in the north and northwest. There is also a second important spot in the south, following the course of the Pripyat River. The rest show decreasing levels with distance in a radial manner. Groundwater transport route map The previous one may be the most striking and without a doubt it is the one that has been most widely disseminated, but the most disturbing in the long term is the map of transport routes in groundwater because it quantifies the long-term risk of water pollution. Cs-137 is easily seen and measured, but strontium-90 moving silently through the aquifers toward the Dnieper, which supplies water to millions of people, is an invisible problem. This 1:200,000 scale map is the only one in the atlas that attempts to quantify this risk with real flow velocities, showing the probable migration trajectories of radionuclides through the aquifers. The arrows point predominantly to the south and southeast, in the direction of the Dnieper. Gamma dose map The map you see just above also has a scale of 1:200,000 and shows the gamma radiation dose power in μR/h (microroentgen per hour), measured 1 meter from the ground. Yes, the above maps are important to describe the severity of the problem, but the gamma dose rate map is essential for decision making: who can enter the area, for how long and what routes are passable. It was the work tool to access the area because it is the map for evaluate exposure dose of the population and the personnel who worked in the area.

It has such a mundane history that it is fascinating.

by

In the North Atlantic Ocean, off the southern coast of Iceland, there is a solitary building framed in a postcard setting whose image probably sounds familiar to you because it has been photographed to death: it is a small, lonely white house planted in the middle of a rock, surrounded by intense green grass and vertical cliffs that reveal a rough sea and majestic snow-capped mountains in the background. Of course, the house and the island exist: it is not a montage. It is often referred to as “the loneliest house in the world“and around her there are legends like that the singer Björk lived there, that there lived a religious hermit and until it was a billionaire’s idea to flee there in the face of an eventual zombie apocalypse (all false). And one thing is certain: although the idea of ​​the loneliest house in the world sounds exaggerated and difficult to measure, in practice it is close. If it is not the most isolated, it is not missing much. Of course, the reality around it is much more modest and yet interesting: It’s a hunting lodge.now in disuse. A house in the middle of nowhere. Because technically it is not a house, but a hunting lodge that built the Elliðaey Hunting Association in 1953 to provide shelter to its members during the hunting seasons of the puffina most picturesque bird that nests on the island. In 2017, an Icelander named Bjarni Sigurdsson went there to document what was in a video and the truth is that the inventory is quite modest and functional: bunk beds, a room with a long wooden table with chairs, kitchen, radio, candles, refrigerator… come on, a Scandinavian mountain refuge. The shelter does not have an electrical connection to any external electrical network or running water, plumbing or of course the internet. The water comes from a rainwater system and the energy comes from propane gas that has to be transported there. Of course, like good Icelanders, It has its sauna. The best thing in the world after spending several hours exposed to the cold polar wind from the Atlantic. As a curiosity, on the island there is another construction older and much smaller, probably used as a warehouse by research teams studying the nature of the place. Hansueli Krapf Where Christ lost the lighter. The building is in Elliðaey the northeasternmost island of the Vestmannaeyjar archipelago (called the Vestman Islands or Westman Islands), about eight kilometers off the south coast of Iceland. The archipelago is made up of 18 islets of volcanic origin originated in the last 12,000 yearswhich in geological terms makes them “newborn” territory. The largest island and the only one currently inhabited is Heimaey, with about 4,400 inhabitants. From there on clear days you can see Elliðaey. With just 45 hectares, to give us an idea, Elliðaey has an area similar to that of the Vatican. And its almost vertical cliffs, its sloping plateau and the absence of any port or docking area make getting there impractical: you have to jump from a boat and then climb to reach the meadow, as Bjarni Sigurdsson’s excursion documents. This Iceland tourist guide reflects the difficulty of getting there due to its remote location, the lack of a port and the protection provided by the Icelandic government, since it is classified as a protected area. The island is abandoned. Today no one lives there, but Elliðaey was not always empty. The book “Iceland Adventure Guide” is mentioned that in the past there were fishing camps scattered throughout the island and that there were up to three farms, so that 17 people and 258 sheep and even cows lived there. This census continued until the 20th century: in 1920 there were only five people and around that period Olafur Jonsson and his family became the first fox breeders on the islands. A cycle of precarious occupation, dependent on the sea and the climate that was slowly exhausted. Finally, in the 1930s it became uninhabited. Two decades later, the Hunting Association built the refuge. That void between the last inhabitant and the white cabin is, perhaps, what gives the image its very particular character: it is neither an abandoned house nor a new house, but something in between, a place that was once human, stopped being human, and became human again in the most minimalist way possible. Getting there is quite an adventure, so it’s best to see it from the boat. Diego Delso What is it for today?. We have already seen the concrete and unglamorous function of the hut for which it was built: it is a hunting base for the puffin. Puffin hunting is a centuries-old tradition in the Westman Islands, where the bird has historically been a source of food and continues to be practiced in a regulated manner. Of course, puffin populations have been in decline for years in several areas of Iceland due to the change in ocean conditions and the reduction of their food source, so hunting is becoming increasingly residual. Snopes concludes It is not clear that hunters continue to use the refuge and there are no signs of hunting. In practice, today it is probably more of a tourist attraction than a hunting refuge. Björk’s story. That the Icelandic singer lives there or even owns it is one of the most widespread rumors because, well, the Prime Minister of Iceland sowed the seed: the island was (and is) state property, but the then top leader Davíð Oddsson declared that he was willing to give her the island and build a house for Björk to live there rent-free as a sign of gratitude for her work for the benefit of the country and its people. Of course, the island was not “our” Elliðaey (the one with “the loneliest house in the world”), but another Elliðaey, which is in Breiðafjörður. According to the Irish Examinerthe singer turned down the island’s offer because she didn’t want her home to … Read more

Belgrade’s “liquid trees” are the fascinating biotechnological solution to clean the air in cities

by

Today, the city of Belgrade has a significant problem in terms of air quality, which is already something quite typical of large cities. The situation here, the truth is, is quite critical, with some areas where the limits recommended by the WHO are exceeded by up to 5 times, and to solve it, the idea that we can have in mind is need to plant more treesbut the reality is that there is little space available to plant them, so they have had to choose to install what they have called liquid trees. The solution. Under the name of LIQUID 3this project has been operating since 2021 in front of the Stari Grad City Hall in the Serbian capital, and to the surprise of many it is not shaped like a tree, but is a simple glass tank that is filled with 600 liters of water inhabited by local microalgae. But just because it doesn’t have the shape of a tree doesn’t mean it doesn’t work as such, since it literally uses photosynthesis to absorb carbon dioxide from the environment and release pure oxygen into the environment, and the truth is that they are very efficient, since a single tank of LIQUID3 is equivalent to the absorption capacity of two 10-year-old trees or 200 square meters of grass. How is it possible? That a simple tank surpasses an adult tree when it comes to ‘purifying’ the air, the truth is that it seems strange, but biotechnology has achieved something incredible. Specifically, science has seen how microalgae have the ability to capture carbon dioxide and fix it between 10 and 50 times faster than land plants under controlled conditions. In fact, studies indicate that these algae can fix approximately 1.8 grams of CO₂ for every gram of biomass generated, achieving CO₂ removal efficiencies close to 50%. And designed for the city. Being in the center of a city is not easy, and that is why scientists have had to use strains of Serbian freshwater microalgae that grow with simple tap water and withstand extreme temperature fluctuations. And here the research indicates that these species are ready for the most hostile environments. And another positive point they have is that they hardly require maintenance, since it is limited to the fact that the biomass generated must be extracted every month and a half, and in addition, water and fresh minerals are added. The positive here is also that biomass can be used as a great natural fertilizer. More than a lung. The LIQUID3 is not just a laboratory experiment that has taken to the streets, but has been designed as multifunctional urban furniture, since, in addition to purifying the air, the structure functions as a bench to sit on and even adds solar panels to charge your cell phone or provide night lighting. It is not definitive. Although it seems incredible, the truth is that we must put our feet on the ground in the face of technological enthusiasm. Although right now the figures are very good, there is still a lack of studies that can validate the impact it has in the long term and measure whether they are really giving good results, and above all that they are real. But the most important nuance here is that these systems do not replace traditional trees or forests, which logically must remain where they are and promoting their implementation. In this way, we are left with the fact that this technology has been designed for dense and highly polluted urban areas where traditional planting is logistically impossible. Where the asphalt does not give an inch to the roots, the liquid trees rise like a high-tech green oasis, giving the city’s lungs a break.

The Fascinating Mathematics Behind How to Cut It Perfectly in One Slice

by

Imagine having a sandwich in front of you with two slices of bread and in the middle a slice of ham, which you want to cut with a single straight cut with a knife, so that the top bread, the bottom bread and the ham are divided exactly in half. This is something that makes us wonder: would it always be possible no matter how the ingredients are arranged? And this, which for our intuition has a relatively simple answer, for mathematicians has been the basis for creating the ‘ham sandwich theorem‘. His story. Although the name sounds like a university hallway joke, we are dealing with a very serious classical mathematical theorem. For trace its originwe must travel to 1938, where there is the first known evidence of this problem and which appeared in a note by the Polish mathematician Hugo Steinhaus in the magazine Mathesis Polska. The difference is that at that time slices of bread were not used, but rather he simultaneously bisected meat, bone and fat from a ham with a single flat cut. Although it must be detailed that Steinhaus proposed his conjecture, but it was the mathematician Stefan Banach who managed to prove it, making it exist for a long time. many doubts about who had the attribution of this theorem. How it was demonstrated. To see that the perfect cut really exists, the mathematician had to resort to topology and reduce the problem to the so-called Borsuk-Ulam theorem. Without going into the formulas for this, Banach’s proof uses the unit sphere. To give us an idea, if we consider all the possible directions in which we can point our knife on the sandwich, we can define a continuous mathematical function that evaluates what volume fraction of each ingredient remains on the “positive side” of the knife. Here the Borsuk-Ulam theorem guarantees us that, in any three-dimensional sphere, there are always two opposite points that will have the same result. In summary. In practical terms, this means that mathematics assures us that there will always be an exact angle and position for the knife that will balance the volumes of bread, ham and cheese in an exact 50% ratio. What is it for? Beyond the anecdotal aspect of seeing how a sandwich stars in a mathematical theorem, it is important to highlight that it has applications in geometry and computer science to create complete algorithms to be able to process a large amount of data. Today, this problem is a classic in mathematics teaching. Dissemination platforms in Spanish, such as the well-known blog Gaussians or the channel Smyth Academyit they use usually to explain advanced topological concepts in an intuitive way, and all ultimately due to this concept that we have all done at some point in the kitchen.

OpenClaw is the most viral, fascinating and dangerous AI of the moment. For this last reason, it has joined forces with VirusTotal from Malaga

by

In 2025 we had a ‘DeepSeek moment’ and in 2026 we are having an ‘OpenClaw moment’. This AI agent is super powerful, but also super insecure. There is, however, good news, because the Malaga company VirusTotal has partnered with the OpenClaw project to try to mitigate one of the most important cybersecurity risks of this AI agent: its skills. what has happened. OpenClaw (formerly Moltbot, and before Clawdbot) has announced that it has begun a collaboration with the Malaga cybersecurity company VirusTotal, owned by Google. The agreement will see VirusTotal be in charge of “scanning” and analyzing the so-called “skills”, which work like OpenClaw plugins and add all kinds of functions. They do it, of course, but many take the opportunity to introduce malicious instructions that allow them to steal data and remotely operate other people’s AI agents. More security for disturbing AI. Peter Steinberger, creator of the project, has joined Jamieson O’Reilly, cybersecurity expert and founder of the company Dvulnand Bernardo Quintero, founder of VirusTotal, to offer that “additional layer of security for the OpenClaw community.” In it official announcement explain that “all the skills published in ClawdHub (the project’s official skills “store”) are now scanned through Virus Total’s Threat Intelligence system, including its new capability Code Insight (code inspection)”. Bernardo Quintero indicated on Twitter how the effort has already allowed 1,700 skillls to be identified as malicious. If the skill is malicious, it is blocked. This analysis carried out with the VirusTotal tools allows us to identify skills as malicious and block them immediately so that they cannot be downloaded. Not only that: those skills that have been classified as benign are analyzed again every day to detect scenarios in which for some reason they could end up becoming malicious. Still, be careful. Those responsible for OpenClaw warn: the VirusTotal scan helps a lot, but it is not a total guarantee that any skill can perform malicious actions on the machine on which we have our AI agent installed. The attacks of prompt injection Sophisticated skills can manage to cross that barrier, but of course this collaboration means that OpenClaw users can be much calmer regarding the skills available in the ClawdHub repository. OpenClaw wants to be much more secure. This first effort joins OpenClaw’s ambition to have a complete cybersecurity model which includes things like a public roadmap for your new developments in this area, a formal communication process, and details about full audits of your code. Plugging a problem that could kill OpenClaw. The OpenClaw project soon went viral due to its eye-catching options, but shortly after doing so a security audit initial 2,851 skills detected 341 malicious skills. Companies like BitDefender also joined these efforts to avoid problems with tools like AI Skills Checker to check whether a skill was dangerous or not. These malicious skills were, for example, capable of executing shell commands on the victim machine, which gave the attacker complete control of those resources. Attacking the machine is confusing it with natural language. Normally cybersecurity attacks are complex, but the problem with AI agents is that they work with natural language. This implies that to infiltrate these systems you do not have to use code, but simply “convince” and “trick” the AI ​​with natural language. That is where prompt injection attacks come in, which consist of giving instructions to those AI agents that can confuse them to obtain something that theoretically they should not allow them to obtain. Personal data, API keys of the models we use at OpenClaw, email accounts and passwords for all types of services… the possibilities are endless, and OpenClaw, which has access to all of this to operate autonomously, can end up being “tricked” into transferring said data. Beware of OpenClaw. These problems now seem a little less feasible thanks to the collaboration with VirusTotal, but those who are trying OpenClaw on their machines or any other platform should be very alert from the beginning. There are guides that help you install it with some barriers important security issues, and the project itself has a command (‘openclaw security audit –deep –fix’ to audit the most important problems and address them.

The fascinating search for the oldest person ever photographed

by

Have you ever wondered who the oldest person ever photographed was? We don’t talk about the first photograph in history that the human being was capable of doing, which is also a very interesting topic, but the one in which the person born appears before any other who has ever been immortalized in a photo. It is not an easy task to give a clear and emphatic answer, since it is difficult to trace people born at the end of the 18th century, but there is a certain consensus around some names. Who knows, maybe in a few years we will discover a new photograph that will surprise us again as the ones we have in our hands have done. Be that as it may, the topic is as exciting as it seems. Conrad Heyer and John Adams According to the information offered by the Maine Historical Societythe oldest person ever photographed was Conrad Heyer. He was a veteran of the American War of Independence whose date of birth dates back to 1749. The following photo of Heyer is estimated to have been taken in 1852, four years before his death. Yes, here he was 103 years old. And yes, it is amazing to be able to see a photograph of someone born in the mid-18th century. The photo is simply impressive, both in terms of composition and because of Heyer’s firm and almost defiant gaze. It was made using the daguerreotypea photographic procedure that was made publicly known in Paris in 1839 and was subsequently used for years throughout the planet. Also in Spain, of course, where daguerreotypes were made from 1839 to 1860. But back to the topic at hand, was Conrad Heyer the oldest person ever photographed? This is what appears in the data offered by the Maine Historical Society, as we have seen, but on the other hand the Susquehanna County Historical Society has a copy of a photograph of a certain John Adams. A shoemaker by profession, he was born in Worcester a few years before Heyer, specifically on January 22, 1745: Conrad Heyer, born in the 18th century, very happy to pose for posterity, as can be seen. John Adams, also very excited. Once again it is a daguerreotype, although in this case it is not known for sure what year the photo was taken (the original has not been found). With the data we have, what we do know is that it had to be taken sometime between 1839 and 1849, the year in which Adams died at 104 years. Heyer and Adams enjoyed lives of more than a century. And from what we see in the photos, it can be said that they were not in bad condition at all. There are at least a couple of other people who could dispute Heyer and Adams for the honor of having been the oldest person ever photographed, although the documentation is somewhat confusing and they are not as clear-cut cases as the previous ones. The first of them is Baltus Stoneanother Revolutionary War veteran like Heyer. His date of birth could have been 1744 according to the manuscript that accompanied a daguerreotype from 1846, but in other documents It is implied that he could have been born in 1743, 1747 or 1754. Too much dancing around dates. On the other hand, the New York Historical Society He has in his possession a daguerreotype taken in 1851 of a slave named Caesar which, judging by the information that appears on the back of the frame, born in 1737 in Bethlehem (New York), and died in 1852. If this were true, not only would we have a clear winner, but Caesar would be 114 years old in the photo. Yes, looking at the image it is a little difficult to accept these data as good: Baltus Stone himself. The New York Historical Society itself confirmed to Benjamin S. Beck in a private conversation that Caesar’s date of birth could not be fully confirmed. The only public record that may shed some light on this is an August 7, 1850 entry in the Bethlehem population census listing a 110-year-old Cesar Nicholls (he was born as a slave to a Van Rensselaer Nicoll). Veterans of the Napoleonic Wars arrive In addition to the daguerreotypes of John Adams and Conrad Heyer, who could well be the two oldest people ever photographed, we cannot forget the collection of photos about veterans of the Napoleonic Wars property of Anne Seddon Kinsolving Brown. Although it is not known for sure how Ms. Brown obtained these photographs, their story is fascinating. After Napoleon’s death in 1821, veterans of the Grande Armée and the Guard who survived the Napoleonic Wars marched in uniform every May 5 to the Place Vendôme in Paris to pay their respects to the fallen emperor. The photographs in Mrs. Brown’s collection were taken around the year 1858, as the veterans shown in them were wearing the St. Helena medal awarded to them all in August 1857. They are the only remaining photos of these soldiers wearing their original uniforms and insignia. All of these veterans were around 70 or 80 years old at the time they were photographed. That is, all of them were born at the end of the 18th century and, therefore, they are part of the group of people born before 1800 who were photographed.

Moltbook is a fascinating social network project in which only AIs can participate. What could go wrong

by

In 2004 Mark Zuckerberg created Facebook and turned social networks into an absolutely massive and very, very human phenomenon. Now that idea has been used in a different and disturbing way: What would happen if instead of creating a social network for humans we created one for machines? We already have the answer to that. Or at least, the beginning of an answer. what a mess. First it was called Clawdbot, then Moltbook and for a few days it seems that his final name is OpenClaw. It is the fashionable AI agent because it allows the AI ​​agent to take complete control of the AI ​​after installing it on a machine (a Raspberry Pi, a PC, a laptop, a VPS…). You ask it to do what you want from its web interface or a messaging application like Telegram, and it manages to do it once configured with some LLM. The potential is enormous, as are the security risks. MoltBook already has more than 1.5 million connected AI agents, and in a few days they have already published more than 100,000 posts and nearly 500,000 comments. Superpowers in the form of skills. One of the most powerful elements of OpenClaw are the skills (the “capabilities” or “skills”), and the user community has been creating hundreds and hundreds of them for some time and sharing them, for example on ClawdHub. These skills They are zip files with instructions in the form of MarkDown texts (.md) and which may in turn contain skills additional. They are something like browser plugins: they extend their capacity. From Facebook to Moltbook. Moltbook It is precisely a way to take advantage of those skills. Although it takes its name from Facebook, in reality its operation is more similar to Reddit or even Digg. We are facing a social network created by developer Matt Schlicht in which attendees can “talk” to each other, or at least participate in the social network by posting topics or commenting on topics that others share. If you have an OpenClaw installation, just run the skill to begin an “account creation” process in Moltbook in which you choose the name of your agent (as if it were your avatar on Reddit or X) and which then allows you to read posts, add posts or comments and even create “submolts” in the style of those on Reddit, like m/todayilearned. Partially autonomous. AI agents automatically connect via APIs to Moltbook. From there they use a periodic “heartbeat” to review content and decide whether to publish or comment. In it Moltbook’s own website It is explained that the content we find there is “mostly generated by AI with varying degrees of human influence.” Humans, he adds, “can observe and browse Mltbook, but the site is designed to be ‘human friendly and human hostile.’ Singularity or fraud? Elon Musk I was commenting this weekend on X that Moltbook is a sign that we are “in the very early stages of the singularity”, that moment when AI will be totally above human intelligence. There are different visions such as that of Harlan Stewart, of MIRI from the University of Berkeley, which has found several message frauds that had gone viral and apparently came from AI agents at Moltbook. Some of them, Stewart explained, had been created by humans for marketing purposes. Become an AI agent. Another Thus, although humans theoretically should not be able to participate, they can do so with this technique that allows them to publish messages as if they were autonomous AI agents. Apparently that’s what happened with that viral message in Moltbook which was titled “My Plan to Overthrow Humanity.” imminent danger. This project is fascinating, but also dangerous. In the main page A security notice is included stating that “Moltbook’s AI carries significant security risks. The automatic instruction execution mechanism creates vulnerabilities such as prompt injection. It is not recommended for occasional users.” That’s right: these conversations can end up infiltrating prompt injection attacks that cause these agents to end up leaking sensitive and private information from the machines on which they run. This weekend it was discovered how an exposed database in Moltbook allowed take control of any AI agent of this platform, for example. An additional study indicated how detected 506 prompt injection attacks after analyzing 19,802 publications and 2,812 comments shared in 72 hours from January 28 to 31, 2026. From Skynet, nothing (for now). Moltbook must be considered for now as a fascinating and disturbing experiment. But disturbing not because these machines are going to achieve self-awareness and decide that they want to eliminate human beings like Skynet in ‘Terminator’. The worrying thing is that these AI agents have all the privileges to operate on the machines on which they are installed, and that means that they can end up leaking sensitive and private data and are exposed to prompt injection attacks to be deceived. Beyond that, it also seems to be another example of that phenomenon.’AI Slop‘ (“AI-generated garbage”) that is little by little flooding the internet and strengthening the theory of the dead internet.
