115,000 years ago, Neanderthals were already obsessed with ‘seasonal cuisine’. The evidence is in a cave in Murcia

by

For a long time, the evolutionary narrative has told us a story of superiority in which the Homo sapiens He survived because he was smarter, more adaptable and above all because he was capable of long-term planning. At his side were the neanderthalswho were seen as a group of opportunistic hunters who lived from day to day without planning anything. But science has been committed to rewriting this history for years. The Spanish case. 115,000 years ago, long before our species set foot on the Iberian Peninsula, Neanderthals already inhabited the Cave of the Planes in Cartagena and even collected shellfish to feed themselves. But they did not do it in any way or at any time, but rather they had a perfectly designed collection calendar. This is the conclusion to which a team has arrived where the University of Burgos and the International Prehistoric Research Center of Cantabria participated, without the need for a time machine, but ‘only’ needed an analysis of oxygen isotopes. How they have done it. Here the researchers analyzed the remains of shells of two very specific species, such as the Phorcus turbinatus popularly known as caracolillo, and the Patella ferruginea. The interesting thing about these is that, as the mollusks grow, the carbonate in their shells traps oxygen isotopes whose proportion varies depending on the temperature of the sea water at that exact moment. By analyzing these layers, scientists found an authentic “prehistoric thermometer”, achieving unprecedented resolution, as they discovered the exact time of year in which the mollusk was collected and consumed. The results. What was seen is that 78% of the consumption of these mollusks occurred in the coldest months, between November and April. On the contrary, during the summer, consumption plummeted to a mere 5%. And here the question is practically obligatory: Why did Neanderthals prefer to go into the coast in the middle of winter to search for shellfish? The answer suggests that during winter and autumn, due to their reproductive cycle, these mollusks have more meat, a better texture and, therefore, a better flavor. But also, by avoiding summer, Neanderthals avoided the rapid decomposition of food due to heat and, much more importantly, they avoided the feared “red tides” that were a proliferation of toxic microalgae that make shellfish poisonous during the warm months. The inferiority complex. The truly important thing about this study is not the discovery that Neanderthals ate shellfish, but rather the irrefutable demonstration that they carried out planned seasonal harvesting. Until now, it was thought that the ability to understand annual cycles and diet planning was a consequence of a cognitive advantage of our species, but now we see that Neanderthals were more advanced than we thought.

I was looking for a good keyboard and I wanted one that would help me work faster (and more comfortably). I already know what I want

by

Between the time I spend working and the time I spend playing on the PC, it can be said that I have my hands on the keyboard for many hours of the day. For years, peripheral that has accompanied me has been a Logitech G513 from which I have learned that I love the wrist rest. However, I think it’s time to retire and I want something different. Since I spend all day browsing almost every store and looking at all kinds of devices, I admit that I have spent more time than necessary searching for a new keyboard. And, in that search, I have found The keyboard that I would like to be part of my setup: This is Corsair Galleon 100 SD and costs 349.99 euros. It has a high price, I know, but there are several reasons why I love it. Corsair Galleon 100 SD RGB Wired Mechanical Gaming Keyboard – Spanish QWERTY, Stream Deck Integration, Pre-Lubricated and Interchangeable MLX Pulse Key Switches, SOCD FlashTap, 8000Hz The price could vary. We earn commission from these links Keyboard with wrist rest and Stream Deck. all together As I say, there are several reasons for this and the first and foremost is what stands out most about this Galleon 100 SD: it is the first keyboard to have a built-in Stream Deck. Beyond the fact that it eliminates something that I had left over from my Logitech (the numeric keypad), this part is super useful and, although it is a gadget that has gained popularity among streamers, It is the best there is to increase productivity. What can be done with it? Well, that’s the fun, since it is very customizable. The simplest thing is to assign each key to open an app, such as Slack or an email manager. This is great, but you can go much further by making A single button opens all the applications you need to work at once. What’s more, you can place specific functions from programs like Excel or Photoshop as well, which allows you to optimize (a lot) the workflow. And to place certain functions when playing it also seems wonderful to me. I have talked about the wrist rest as a point that I love, but a small nuance must be made here. Many of these accessories that can be found on Amazon or similar stores are made of plastic and, although they do not have to be bad, I find them uncomfortable. However, this Corsair has a memory foam wrist rest like the Logitech keyboard I already have, which provides great comfort even if you spend a lot of time with your wrists resting non-stop. Finally, two more details. Its switches, which are MLX Pulse, have short travel and, although they offer an audible response, They don’t sound like an old typewriter.. Furthermore, although it is not something that matters for working, it has a polling rate of 8,000 Hz, which makes its response time very top. I left out some extra things that this Galleon 100 SD has such as the LCD screen, the wheels to control the sound or the materials of its keys, but even so it is an option that seems like a real spectacle to me. It is not a keyboard for everyone nor is it an economical option, as I say above, but it is a very interesting option if, like me, youYou spend many hours with your hands on the keyboard to work and play.

Someone has looked at the temperatures under the Pacific and found a terrible forecast for next year

by

On September 1, 1513, on the verge of despair, Vasco Núñez de Balboa left Santa María de la Antigua in search of “a new sea rich in gold”. It took weeks and he lost dozens of men, but on the 29th of that same month he was the first known European to reach the shores of the South Sea. We still called him that. Seven years later, Magellan (emerging from that enormous and labyrinthine hell of canals, hurricane winds and storms that we call Tierra del Fuego) He called it Pacific and the name stuck. But there is nothing peaceful about it. That huge chunk of water concentrates most of the planet’s seismic and volcanic activity, generates the most violent typhoons, and is home to some of the most severe extratropical storms that exist. And I haven’t talked about El Niño yet. What about El Niño? We have been talking about the 2027 ENSO event for the past few days. We have always done it with quite a worrying tone and the truth is that, the more we know, the less exaggerated it seems to me: there are meteorologists who already describe the subsurface heat of the equatorial Pacific as “possibly the blob of warm anomalies ever recorded since we know how to measure these things“. And, as I say, it is not an informative “outburst”: the heat that is moving eastward beneath the tropical Pacific is (in volume and intensity) comparable to or greater than that which preceded the great Children of 1997-98 and 2015-16. What’s more, that heat is moving across a planet that is already 1.4 degrees above the pre-industrial level. Why are we getting nervous? This, I think, is the central question. First of all because what is invisible matters more than what we can see. In fact, “what we can see” (what we can measure on the surface of the ocean) is simply a trailer for what we are going to see in the coming months. It is true that the mechanisms that allow coupling between the ocean and the atmosphere are always mysterious and the uncertainty is great. However, as we move out of spring (the time that most “confuses” the models) the quality of our data increases. The problem is that, these new data, They only corroborate (little by little) our first intuitions. Of course, caution is necessary. Both ECMWF and NOAA they ask for caution and yes, it is important to be cautious. In one month, the scenario of having a Child before summer has suddenly become very likely and this growth in probabilities has left us all out of the loop. The public conversation, as a consequence, is getting out of control. But in reality, we are in completely uncharted territory. The problem with being unprecedented is that we grope in the dark. If we move forward. Today, there is only one clear idea: as in the 19th century, what happens will depend on the decisions we make.

Argentina and Taiwan have hundreds of Chinese fishing boats in front of them. And no one has cast their nets into the sea to fish

by

In January 2026, a NASA satellite captured off the Argentine coast a strange image: a huge luminous spot floating in the middle of the South Atlantic, so bright that it looked like a city that had suddenly appeared on the ocean. From the ground nothing could be seen, but from space, however, it was impossible to ignore it. The new floating wall. Last February we count what was seen through satellites, and since then it has not stopped repeating itself. For years, the world assumed that Chinese fishing boats were just that: boats dedicated to fishing. In 2026 that perception is changing rapidly. From the South China Sea to the South Atlantic, different governments are observing the same phenomenon: enormous chinese civil fleets remaining for weeks in strategic areas without clear fishing activity. To be more exact, Argentina and Taiwan, separated by half a planet, now face a surprisingly similar situation: hundreds of Chinese vessels off their coasts whose function seems to go far beyond catching fish. What is disturbing is not only their presence, but the growing suspicion that Beijing is using apparently civilian ships like tools permanent geopolitical pressure and maritime surveillance. Get paid to occupy the sea. I counted last April the ABC chain that investigations into the so-called Chinese “maritime militia” have shown the extent to which Beijing has professionalized this strategy. In the South China Sea, many ships receive state subsidies simply by staying in certain disputed areas. The crews spend entire days at anchor, with hardly any fishing activity, while they help consolidate the Chinese presence around reefs, maritime routes or foreign military exercises such as Balikatan. For Western analysts, the goal is clear: physically saturate the sea with civilian vessels to intimidate rivals without the need to directly deploy traditional military units. Taiwan discovers that anyone can be a problem. The pressure on Taiwan has made this tactic much more visible. This same month of May, Taipei expelled to the Chinese scientific vessel Tongji after detecting suspicious operations near the island. Officially he was carrying out oceanographic studies, but Taiwanese authorities suspect that collected strategic information on the seabed and nearby waters. The incident reflected the great problem what Taiwan faces: It is already difficult to distinguish between civil ships, scientific ships, coast guard ships or military support platforms. That is why the island has even begun to adapt its coast guard patrol vessels to carry anti-ship missiles and act as part of national defense in the event of conflict. Argentina sees the same pattern. Also in May, Reuters reported an extensive report. Thousands of kilometers from Asia, Argentina has been observing another enormous concentration of Chinese ships in front of its waters for years. Every season, about 200 fishing boats illuminate the South Atlantic during squid fishing, forming a gigantic floating city visible from space. Although they officially carry out legal fishing activity outside the Argentine EEZ, Washington and part of the Argentine defense apparatus suspect that many of these vessels could be gathering intelligencemapping the seabed or measuring local surveillance capacity. The context makes the issue especially sensitive for a reason: the area is close to the Strait of Magellan and the access to Antarctica, two strategic areas of enormous geopolitical value. Master the sea without shooting. For its part, China denies that there is any military use of these fleets and maintains that their ships act according to the law international. However, it is becoming evident to many countries that Beijing has found a very effective way to expand its maritime influence without resorting to open war. In other words, the real change does not seem to be in the Chinese destroyers or aircraft carriers, but in the ability to bind a huge number of civilian ships in the ocean until the border between fishing, surveillance or strategic intimidation becomes unrecognizable. Meanwhile, Argentina and Taiwan are already seeing the same reality: one where there are hundreds of Chinese boats off its coast, and with each passing day it seems more strange that everyone has gone there so as not to cast their fishing nets.

OpenClaw led the way for AI agents. Gemini Spark is Google putting a toll on it

by

In January of this year the technological world was amazed by OpenClaw (at that time Clawdbot), the most powerful AI agent that we had seen to date, capable of taking total control of the computer and everything open source. Technology companies took good note of this and some like Pereplexity or NVIDIA They have set out to copy it. Google just joined the party. Gemini Spark. This is how they have named this personal agent based on Gemini Flash 3.5 that, in the words of Google itself, “helps you manage your digital life.” With Gemini Spark you can assign it a task and it will start working on it autonomously, even with your phone and computer turned off. Google emphasizes the issue of security, which was a major concern with OpenClaw, and says that Spark is designed to “consult you before taking important actions.” What Spark can do. Because it’s integrated with all Google Workspace tools, Spark can perform complex tasks like making a document with a party’s attendee list from the information you receive in email. You can also schedule recurring tasks, like reviewing your bank statement at the end of the month for strange charges, organizing your drive files, or creating workflows from meeting notes. Who can use it. Here comes the main difference with OpenClaw and that is that Gemini Spark is obviously not free. Google has confirmed that its new agent will be part of the Google AI Ultra subscription. In Spain that means paying a minimum of 100 euros per month (there is a 220 euro plan with more features and storage), but even if you want, you won’t be able to try it because at the moment it will be launched in beta version only for US users. At the moment there is no confirmation of when it will reach other languages ​​and countries. When available, Gemini Spark can be used on Android, iOS and in the web app, but they have also talked about integrating it directly into Chrome. Why is it important. The viral success of OpenClaw earlier this year showed us how far a single person can go with a good AI idea, and how short-lived that sweet moment was. Not even three months had passed when OpenAI signed its creator and shortly after we began to see large companies copying the idea. Perplexity with Personal ComputerNVIDIA with NemoClaw and now Google with Gemini Spark. A single open-source project has set the agenda of an industry that has swallowed it in the blink of an eye and returned it to us in the form of a monthly subscription.

turning smart glasses into instruments of war

by

Anduril and Meta join forces. What began as a race to conquer the “metaverse” with devices like the Quest has transformed into something very different. Specifically, in a contract of 159 million dollars that Anduril and Meta have jointly signed to develop smart glasses that enhance the operational capacity of soldiers on the battlefield. This joint project is being developed in parallel with the Anduril helmet with assisted vision system, called EagleEye. War made video game. These augmented reality glasses provide the soldier with an integrated system that theoretically displays a map, identifies enemy vehicle profiles, calculates shooting distance, processes threats in real time and overlays tactical data on the wearer’s physical environment. The future vision of these companies is to add special functions, such as being able to order a drone attack thanks to eye tracking and voice commands. War made video game. From consumers to soldiers. It is ironic that a technology that was originally used for entertainment applications ends up having a military purpose. Anduril provides its software platform, called Lattice, which acts as the “brain” of the system, fusing the data captured by the glasses with that received from the rest of the battlefield network. The ethical challenge. If an AI decides what a target is and displays it prominently on the soldier’s glasses, is the room for human error reduced or are we simply automating violence? This gamification of war is increasing and the danger is evident: treating a combat environment almost as if it were a video game can make it difficult to distinguish between civilians and combatants, for example. If the metaverse doesn’t work… Meta has an opportunity here to recover part of the gigantic investment it has made in the field of virtual and augmented reality. After losing tens of billions of dollars with the metaverse, Mark Zuckerberg has decided leave these solutions in the background in the end-user market. And he has also seen clearly that his advances could have a very juicy military application. The geopolitical factor. There is no doubt that both in Silicon Valley and in the rest of the world there is one huge demand of new technological solutions applied to the battlefield. The conflicts that have occurred in recent years have caused skyrocket defense budgetsand here both Anduril and Meta wanted to take advantage of their opportunity. Microsoft missed its chance. In Redmond they had a fantastic product with Hololensbut its role in the end-user segment was never clear, and the company refocused it on first- and then to the military sector. Here the failure was enormous despite the investment of 22 billion dollars that the US Army carried out in this area. Meta and Anduril have wanted to take the baton, but they will not be alone: ​​companies like Rivet either Elbit They have projects that compete to become the new “weapons” of the soldier of the future.

bought $87 million worth of ETH and sells it all in one quarter

by

The Harvard investment fund prepared to buy Ethereum in autumn of last year. Three months later, he ended up selling everything. At the same time, it has continued to reduce its position in Bitcoinwhich has also been declining quarter by quarter since will reach its all-time high in mid-2025. The institution, which for a few years had been increasingly betting on cryptocurrencieshas experienced first-hand how the landscape has changed in a very short time. The play. The Harvard investment fund, known as Harvard Management Company, revealed in its latest filings with the SEC that it had completely liquidated its position in BlackRock’s Ethereum ETF during the first quarter of 2026. The position, valued at around $86.8 million, lasted just one quarter. In fact, at the time of purchase, the fund had become the largest new buyer of BlackRock Ether, as commented Bloomberg analyst James Seyffart told Fortune. At the same time, Harvard also cut its position in the Bitcoin ETF of BlackRock (IBIT) by 43%, leaving it at about 117 million dollars. It is the third consecutive quarter in which its crypto positions decrease. Why it matters. Harvard is not just any university when we talk about investment. Its endowment (the university’s permanent investment fund) is the largest in the world and many are attentive to its movements. That it has bet (and undone so quickly) on Ethereum gives clues about how institutions are viewing this cryptocurrency. The thing about Ethereum is that it has something that Bitcoin doesn’t have. And its network can host financial applications. That should make it more attractive in theory. However, what the numbers say is something else: the price of Ethereum has accumulated a drop of 29% so far this year, compared to 12% for Bitcoin, and in the last five years Bitcoin has clearly surpassed Ethereum. In detail. Harvard’s crypto story begins in the second quarter of 2025, when bought 1.9 million shares of BlackRock’s IBIT ETF for about 116.7 million dollars, making Bitcoin its largest position in listed equities, even above Nvidia or Alphabet. The peak came in Q3 of 2025, with 442 million in Bitcoin ETF. From there, the road was downhill, with a 21% cut in Q4, simultaneous entry into Ethereum for 87 million, and in Q1 2026 complete exit from Ether and a new 43% cut in Bitcoin. Between the lines. The exit of Ethereum in a single quarter suggests that it was a strategy that did not end up convincing. Harvard’s portfolio of listed equities It is only 16 positionsand this is a tiny fraction of its total $57 billion endowment. Its largest position currently is TSMC, with about 232 million, followed by gold, with about 200 million. Eric Balchunas, ETF analyst at Bloomberg Intelligence, counted Fortune that flows into Bitcoin ETFs remain relatively resilient despite the fall it is having in 2026. Regarding Harvard’s position specifically, he noted that, having many other assets that have performed well, “absorbing losses in Bitcoin may be more bearable, with the hope of a recovery.” He also recalled that endowments are “the most difficult institution to convince” to enter ETFs, which makes both entry and exit even more striking. ETFs at other universities. Among the rest of the universities, the panorama is different. Dartmouth maintained its position in IBIT unchanged during Q1 and expanded its crypto exposure with a new entry into Bitwise’s Solana ETF, being one of the first US universities to do so. Brown University He didn’t move his position either. at IBIT. Harvard, for now, is moving in the opposite direction. And now what. Harvard’s crypto strategy could also be conditioned by an internal factor. And NP Narvekar, the director of the endowment since 2016 and the architect of its shift towards alternative assets, has informed the board of his intention to retire, possibly at the end of 2027, according to account the Wall Street Journal. There is still no open successor search process, but it is a factor that may explain why Harvard is getting rid of somewhat riskier positions.

What it is, what Google Video Creation AI offers and how to use it

by

Let’s explain to you What is Gemini Omni and how does it work?the new artificial intelligence model created by Google. It is a model capable of generating videos from any type of input, which will give free rein to your creativity. Let’s start this article by explaining to you What Gemini Omni is and what it can doso that you understand why it is so revolutionary and all the options it offers Gemini with the. Then, we will explain how it works. What is Gemini Omni and what does it offer? Gemini Omni is Google’s model for create videos using artificial intelligence. With it, the search engine company aims to revolutionize video creation by AI Just like you revolutionized imaging with Nano Banana. The first version of this model is the Gemini Omni Flash, and it is expected that new versions will arrive in the future. This is a model that allows you to create content from any type of input. This means that you are going to be able to combine images, audio, video and text in your prompts when asking the AI ​​to generate the video. Gemini will use its real-world knowledge to make the videos coherent and realistic. In fact, Google not only proposes Omni as a tool to generate videos from scratch. It also says that it is a system capable of working on a scene through chained instructions. Come on, you’re going to be able to change only specific elements of a video or transform everything completely. Omni is the substitute for I SeeGoogle’s previous video creation model. It will allow you to create clips of up to 10 seconds, with native audio generation. You can also convert photos to video with a maximum of 5, and edit various interactions. When creating or editing videos, Omni will allow you adjust aesthetics, actions, environment, angle or style of a video, as well as specific details. It also allows maintain character consistency and preserve the continuity of the scene, also offering coherent physics. With all this, Omni will allow you to do things like change the style of a video, making it into cartoons, for example. You can create videos from an image, add audio, change specific elements of the video such as a person for a creature, etc. Who can use Gemini Omni At the moment, Gemini Omni is available only for paying users with any Gemini subscription. It integrates directly into both the Gemini and Flow app and website. You will have an option to use Omni for freeand will be using YouTube Shorts and YouTube Create App. However, to use it natively within the Gemini app you will have to pay. How Gemini Omni works To use Gemini Omni, you have to enter Gemini and display the writing box options menu. In the menu that opens, Click on the option Create video. When you do so, below the field where you can write your prompt you will see that the video option has been permanently marked. You will go to a screen where you have various styles and ideas from which you can choose just by clicking on them. But at the bottom you can also write your prompt by hand adding elements such as videos, images or audios. For example, you can add a video and explain to the AI ​​the changes you want to make in it. Remember that you can change elements within, replace them with others, use the video as a basis for a creation or whatever you want. You can also upload images and audio and generate videos from them, or even just make a video from scratch. And that’s it. In a few minutes Gemini will create the video based on the elements you have added and the request you have made. When it’s done, you can watch the video, redo it, share it, or download it to your device.

Almost 2,000 years ago a man died with a mysterious case while fleeing Pompeii. We finally know his secret

by

Get in the situation. It’s any day of any month and you are at home doing something when suddenly you hear screams in the street. You look out the window and see people running away in terror. Not only that. In the distance you see how the ash and burning rock rise from a volcano that both you and the rest of your neighbors thought were immersed in unalterable lethargy. What would you do in the face of such a scenario? something similar They lived 1947 years ago the Pompeians. Now we finally know what one of the unfortunate people who did not manage to save himself did: hold on to your briefcase of doctor. When Vesuvius woke up. The ruins of Pompeii were discovered long ago several centuries and archaeologists have been unraveling its mysteries for decades, trying to know above all what happened that fateful August 24, 79 AD (some versions speak of October) in which Vesuvius erupted and condemned the city of Campania, along with other towns such as Herculaneum, Stabia and Oplontis, asphyxiated under a layer of ash. However, despite all the research and rivers of ink that have flowed on the subject in recent years, the ruins of Pompey continue to retain their ability to surprise us. A figure in Ortho dei Fuggiaschi. One of the corners that has aroused the most fascination is the Ortho dei Fuggiaschithe ‘Garden of the Fugitives’, where we have found the remains of some 13 victims of Vesuvius. The reason is very simple: thanks to the method archaeologist molding Giuseppe Fiorelli20 centuries later, their corpses continue to starkly reflect the desperation of those men, women and children who tried to save themselves while their city was eclipsed by a dense rain of ash and lapilli, the walls collapsed and Vesuvius spewed pyroclasts. We knew that the victims who ended up perishing in the Ortho dei Fuggiaschi were probably seeking refuge, we also have a fairly precise idea of What were your last moments like? before dying. Thanks to Fiorelli’s plaster mold method we can even visualize the scene. The big question is… Can we go further? Who were those people? What did they do? What did they do before leaving their homes on the run? They are fascinating questions. Especially because, before perishing, some victims of Vesuvius they left us clues about your routine. There are cases, for example, in which the scene suggests that the victims were carrying jewelry and coinswhich leads us to think that they were trying to keep their most valuable possessions safe, perhaps so as not to lose them. Perhaps to start a new life in an impulse not so different from the one we would have today. Clinging to the medicine cabinet. Now researchers have discovered another story in it Ortho dei Fuggiaschil. More than 70 years after the first excavations and thanks to the use of To be more precise, scientists have identified a small box of organic material with metal parts and a series of instruments “compatible with a medical kit.” For example, a slab of slate that could have been used to make medical or cosmetic substances and surgical instruments. The x-ray and tomography examination has also shown a cloth bag with bronze and silver coins and a mechanism with a toothed wheel that allowed the box to be closed. Those responsible for the site stand out Furthermore, the study was carried out without putting the molds at risk. The decline of a doctor? That is the hypothesis with which the researchers work, who believe that the briefcase gives us a clue as to who the person who died next to him was. “He was probably a doctor, a victim of the tragedy while trying to escape, taking with him some of the tools of his trade,” he explains in a statement the Archaeological Park of Pompeii, which insists that the instruments located inside the case provide us with “a valuable and rare clue about his profession.” “2,000 years ago there were people who were not limited to practicing medicine during office hours, but were doctors at all times, even when fleeing the eruption, which was thwarted by the pyroclastic cloud that reached the group of fugitives who were trying to leave the city through Porta Nocera,” reflect Gabriel Zuchtriegel. “This man took his instruments with him to be prepared to rebuild his life elsewhere thanks to his profession, but perhaps also to help others.” Images | Pompeii Archaeological Park In Xataka | 2,000 years later, Pompeii continues to reveal fascinating things: the latest is a blue room for unknown uses

Starlink has been ruining astronomers’ nights for years. Now it turns out that their launches are leaving their mark on the climate

by

Much has been said about the great light pollution that generate the Starlink satellites from SpaceX. However, not so much has been said about something that, if we think about it, is much more evident. Air pollution derived from launches. Any space launch, in fact, can generate this type of contamination. However, satellite trains require such a large number of launches that it is not unusual for them to be of particular concern to scientists today. 15,000 satellites and counting. A team of British and American scientists has carried out Recently a study brought this problem to the fore and predicted what the effects could be in the short term. This investigation indicates that there are currently around 15,000 telecommunications satellites in orbit, more than 10,000 of which belong to SpaceX. This represents three times as many satellites as in 2020 and the worst thing is that the number continues to increase. As a consequence, according to the simulations of these researchers, by 2029, these satellites could account for 40% of the atmospheric pollution derived from space activity. Also have calculated that by then this sector will be releasing around 870 tons of soot into the atmosphere annually. It would be more or less the same amount released by all cars in the United Kingdom, so action must be taken as soon as possible. Launch and reentry problems. The two key points at which these trains of satellites will put our planet’s climate on the ropes are launch and re-entry. With the first, a large amount of black carbon. These are fine carbon particles that come from the incomplete combustion of fossil fuels. Regarding reentry, it mainly releases aluminum oxides. The satellites must be changed every 5 years. Later, when orbital conditions are favorable, this re-entry can occur, the price for which for the planet is also very expensive. The effects. Black carbon is harmful to the Earth’s climate on two levels. On the one hand, the particles that make it up have a great capacity to retain the heat of the Sun. That is why they play a very important role in the global warming of our planet. On the other hand, they can affect cloud formation in two different ways. Sometimes they prevent their formation, causing droughts, and other times they trigger extreme rainfall. Regarding aluminum oxides, can damage the ozone layerwith all the harmful effects that this entails. The place matters. The main problem with the release of these polluting substances is that it occurs in the highest layers of the atmosphere. The contamination at this height, if space activity did not exist, would be residual. However, the launches deposit that black carbon there, which remains for 2 to 3 years, retaining heat and affecting the clouds. That is why black carbon derived from space activity is estimated to have a much greater effect on the climate than that of ships, cars or power plants, for example. What is to come is very dangerous. It is said that Elon Musk wants to launch a million satellites into space. This is possibly an exaggerated figure. But it is clear that SpaceX has enormous objectives set. In fact, already It is even looking for launch platforms outside the United Statesbecause in his native country there is no room for such ambition. To all this we must add that other companies have increasingly ambitious objectives with their own satellite trains. This is, for example, the case of Amazon with Leo. The situation can become very worrying if alternatives are not sought, such as less polluting fuels for launches or more durable satellites that require fewer re-entries. Science will probably take us there at some point; but, in the meantime, the consequences for the planet will become worse and worse. We have time to solve it, but we must act now.
