What if the constants of the universe are not so constant? We have taken an important step to know. The key is on the nuclear clock

Atomic watches have meant a before and after in our ability to measure time in an outraged way. These types of watches are precise at such a level that some of the most exact ones would be discouraged in less than a second at the time in which the universe has been existing. Despite this, these watches are not precise enough to solve one of the most important unknowns in physics. Closer to the nuclear clock. Now, however, we are a little closer to achieving a milestone that can open the door to solve this type of doubts, Nuclear watches. These watches will allow us to advance several orders of magnitude in the creation of time measurement apparatus, ultra -precise watches to investigate the new physics. From atomic to nuclear. The nomenclature can lead to confusion, and when we talk about atomic watches and nuclear watches we are not talking about the same technology. While the mechanism of atomic watches depends on the state of excitation of the atom electrons; in the Nuclear watchesthis depends on the particles in nucleus. As its name indicates. Atomic watches depend on the transitions in the state of their electrons. When they absorb energy, they can “jump” in their state. Jumps that can be reversed, only when this occurs, it is the electron that emits energy in the form of electromagnetic radiation. Something similar occurs in the nucleus of atoms, only that, being the most isolated nucleus of other physical interactions external to the atom, the transitions of their subatomic particles would be even more precise and reliable than those that occur in the atomic “shell” formed by electrons. Torio-229. To make a nuclear clock work, we also need to transfer energy to the atom, to its nucleus, of course. When we hit the nucleus with a specific frequency of electromagnetic radiation, we can change its energy state, as if it were a switch. Nuclear watches, such as atomic, would only have to tell the energy changes in this context. The problem is that causing these jumps in the atomic nucleus is also more difficult. The main difficulty is to excite atomic nuclei enough to cause the “jumps.” To do this we must hit these coherent X -rays nuclei, a high frequency X -ray type and therefore high energy. So much that, in general we do not have the necessary instruments to produce them. “In general”. And, as with electrons, not all these “jumps” require the same energy. Almost half a century ago, researchers realized that the isotope atomic nuclei Torio-229 (229th) It had a jump that required the energy equivalent to that of ultraviolet light. When requiring less energy, building a laser capable of transferring energy to the nucleus, it became Something feasible. Half a century of work. The “Nuclear Transition” of Torio It was discovered in 1976. But that was just the beginning. And it would not be until 2016 that we would observe and measure it. Measure it is key, since if we want to force the transition we must know the exact frequency with which we have to “bombard” the atomic nucleus of this isotope to be able to force it and activate the process. How close are we really? A few months ago, a group of researchers He tested Some of the key elements behind this technology, which allows us to get an idea of ​​how close we are to be able to create a nuclear clock based on 229th. The team tested an ultraviolet laser capable of creating precise energy to force jumps in the state of the nucleus. He also studied a “frequency grid” to directly measure these jumps. In addition, they also studied the transition from Torio-229. The details of the study were Published in an article In the magazine Nature. From dark matter to universal constants. And all this for what? Do we really need more precise watches than atomic? The truth is that this new technology would have important benefits, first for the scientific community, but also for all citizens. These watches They can help us to improve technologies such as GPS and other navigation systems; And also global Internet synchronization, also making the connection faster and safer communications. We would also open the door to more precise measurements that help us clarify some of the mysteries that persecute physicists such as dark matter. Maybe more importantly, these watches could help us develop experiments that resolve One of the most important doubts of physics, the one of universal constants They are really constant And they do not change depending on factors such as the age of the universe or the frame of reference in which we find ourselves, as we until now assumed.

Spain was not one of the first to step on Antarctica, but now it has one of the most coveted laboratories on the continent

The Antarctica It is a huge frozen desert, but also one orUnique portunity for research. Spain is one of the more than 30 countries that have Bases in the territory And one of them, Gabriel de Castilla’s, has just been extended to be able to carry out a broader range of projects. The peculiarity is that its construction has been carried out in record time and will allow a boost to the investigation of the Climate change and the Biodiversity With a particularity: Spanish is one of the three clean laboratories on the continent. Only. We have been decades studying Antarctica From the air. Is what is allowing us to know What is it under that layer of icebut we also have been studying at Antarctica from the ground. He Antarctic Treaty of 1959 It is the one that allowed different countries to establish bases on the continent, exclusively for peaceful and scientific purposes. However, before that there were already bases such as Orcadas base from Argentina, which were operating continuously in the field. The reason is that it is a Single scenario For research. Not only for its diversity or for the dry atmosphere that allows to install advanced astronomical observatories, but because we can reconstruct the climate of hundreds of thousands of years thanks to the air bubbles trapped in the ice and, above all, it is a Climate change thermometer. Spanish Antarctica. We owe several findings to the field research, being one of the most notable the discovery of the ozone layer in 1985. As a result of those agreements, Spain could establish Two bases in Antarctica. The most veteran is the Juan Carlos i. It was inaugurated in early 1988 and is operated by the CSIC. It is not busy all year, but maintains automated records when there is no one and supports projects of areas such as biology, geology, weather and glaciology. The other is the Gabriel de Castillaopened a year later and operated by the Army. Its operation area is diverse, with research in the fields of earth sciences (geomagnetism, volcanic surveillance or geomorphology, among others), biological sciences (ecology, ethology or microbiology), environmental sciences (climate change) and disciplines such as physics, mathematics or biochemistry. Gabriel de Castilla. Like Juan Carlos I, this base is not always busy. Spanish work is limited to the months of the Southern summer, which occurs between December and March, and its location is unique because it is next to one of the two active volcanoes of Antarctica. This makes it a unique enclave to study geological processes and extreme ecosystems. But it seems that the base fell short, so a new scientific module has been built. In the upper image we see what the base was like. In the lower one, those small modules have been eliminated to leave the new space. Reform reforms. After an investment of two million euros, the Gabriel de Castilla has been able to expand its surface to about 307 m². Thus, he has been able to improve his equipment thanks to a microscope room, an electricity and electronic space, a sanitary module and a clean laboratory. And we might think that in such an extreme climate the construction would go slow, but no: in 70 days of the plane to having a structure that already expects research equipment. As points The army, 700 panels, 400 profiles, 26 screws and a total of 80 tons of material have been used to create a new module 41 meters long by 7.2 wide and another 7 high. In case you wonder, beyond the heating, the walls have a 50 millimeter polyurethane sandwich -type layer and another 60 millimeter inner layer of rock wool to improve thermal protection. Clean laboratory. But beyond the speed in its construction, the most important thing about the ‘new’ Spanish base in Antarctica is the aforementioned clean laboratory. It is a space designed to minimize external pollution, so research processes can be carried out in a practically aseptic space in which the samples are not contaminated with exterior agents. The protocols are very strict in both cleaning and ventilation and disinfection, and the really important thing is that, of the more than 30 bases present in Antarctica, that of the Gabriel de Castilla is one of the three Clean laboratories from the region. As they detail in This video From El País, it will be shared with Portugal, and one of the objectives will be to analyze pure samples to better understand the human impact on the planet without external interference.

Huawei has just said goodbye to Android by Deepseek. And this strange folding is the first step

I had announcing the movement For a few months, and it has finally materialized on a phone. Huawei He just said goodbye to Android in his native countryand he has done it with a curious phone with an never seen aspect relationship. This is the first phone that lands on the market with Harmonyos Nextthe operating system completely developed by Huawei with its own kernel and without a trace of Android. In addition to premiere operating system, it is the first Huawei device to release Harmony Intelligence, its AI in collaboration with Deepseek. Goodbye to Android. The day came. Huawei has presented its first phone without a trace of Android, the Huawei pure x flip. To date, the company’s mobiles were marketed in China with Harmonyos. An operating system that, although the company wanted to completely disconnect from Android, was based on its nucleus. With Harmonyos Next things are different. This is an operating system developed from scratch, does not use Android code, is not compatible with its apps (at least, not if these are not modified) and uses its own core (HMS or Huawei Mobile Services) instead of the Google Application Service. This is the first 100% Harmony mobile. The first step for AI. Harmony Intelligence It is your alternative to Apple Intelligence and Samsung Galaxy AIpromising to go beyond an assistant for AI. This AI has trained both the Pangu model, developed by Huawei, and in Depseek, a model that is permeating quickly in Chinese mobiles. “We have trained our AI assistant for millions of hours with our large -scale language models and we have taken that intelligence to the device for the first time, so that it looks like a human and interact naturally, with conversations with different emotions and detecting the user’s mood.” As Richard Yu, CEO of Huawei promises, the focus is that the person-one interaction is as natural as possible, coming to promise that the assistant will be able to detect user’s emotions (it has not been detailed how). In a more landed plane, it will be able to eliminate photographs objects, generate and modify them, convert voice, and even describe the objects that the telephone camera sees, so that people with accessibility problems can “see” through the mobile. Another especially curious function is to be able to read books without touching the phone: we can pass pages only with our eyes. Huawei wants a 100% own ecosystem. The key here is not that a Huawei mobile releases its AI, is that Huawei is already prepared, in agreement with Deepseekto compete with the greats of the industry. Harmonyos Next is a platform oriented to all types of devices, from home to the connected car, and this first jump presenting Harmony Intelligence is key to the Chinese manufacturer. The company has advanced that its first platform for PC (Harmonyos Next brought to desk) will land in May, and it is expected that throughout the year we will start to see this operating system in virtually all new products that launch the market. The pure huawei. The lucky one who has released Harmonyos Next is the pure x, a folding phone in appearance ratio 16.10 when it is deployed. It is a telephone that, being folded, has a 3.5 -inch screen with 980 x 980 resolution, 2,500 peak shine nits, LTPO technology and appearance ratio 1.1: completely square. Upon opening, a curious 6.3 -inch panel is displayed with resolution 2,120 x 1,320, a completely different format than we are used to. The camera system is triple, with 50 MP for the main camera, 40 MP for ultra wide angle and 8 MP for 3.5X teleobjective. It has a 4.720MAH battery with a fast charging of 60W and will be sold in China at a price that starts from 7,499 yuan (just over $ 1,000) in its 12 + 256 GB version. At the moment, far from Europe. If the question is whether Huawei’s plan to completely end its Android dependence, the answer is no … for now. In Europe, the company is looking for alliances with developers after projects such as Aurora Store to facilitate the installation of Google services in its terminals (something that is easier than ever), and betting on EMUI based on ancient Android versions. The key to Harmonyos Next ends up being global is in the Chinese manufacturer alliance with the rest of the developers and technological. In China, Google apps or giants as a goal (Instagram, WhatsApp and Facebook) have hardly any presence, in our territory they are an essential for a good part of the users. Currently, they can be installed in EMUI thanks to the microg Google Services framework. Without it, the matter is complicated.

Goal has taken the first step to dismantle its external verification system. And he has done it with an X algorithm

Shortly before Donald Trump returned to the White House, Mark Zuckerberg announced What a goal would end his Third Party Data Verification Program And I would bet on a system of community notes in the purest X style, the social network of Elon Musk, one of the leading allies of the new president. With this decision, goal sought Leave in the hands of users The task of pointing out and contextualizing misinformation on Facebook, Instagram and Threads. When Zuckerberg made the announcement, it was clear that, although the company pointed out with this new approach, its implementation would gradually begin in the United States. There were no indications of a possible deployment in the European Union, where the Digital Services Law could mean an obstacle. Now, with more details about the initial launch, we can get a better idea of ​​its operation. Fixed goal in the calendar the beginning of its new initiative. The social networks giant He said that It will begin to test the community notes on March 18. That is, in less than a week, this new approach will take its first steps. As planned, the deployment will be gradual and will be limited, for now, to the United States. From that day, the program taxpayers will begin to leave their collaborations. How will the system work? The community notes system in Meta allows users to add context to publications that can be misleading or need additional information. However, not any note is published immediately: there is an evaluation process that, as explained by Meta, seeks to ensure that contributions are useful and reflect different perspectives. A collaborator detects a publication on Facebook, Instagram or Threads that needs context. For example, a viral post says: “Bats are completely blind and depend only on sounding to move.” The collaborator writes an explanatory note. It must have a maximum of 500 characters and include a link to a reliable source. Example: “It is a common myth. Bats are not blind; They have good vision and combine ecolocation, hearing and smell to adapt to different environments. More info here: (Link). “ Other collaborators check the note and vote if it is useful. It is not published automatically. You must have the support of people with different perspectives, not just with a majority. If the note receives enough support, it is published. It appears next to the original publication to give context. The publication about bats is still visible, but with the explanatory note. Goal will use the X algorithm. The company led by Mark Zuckerberg has chosen to use, in a first stage, the algorithm of the notes of the community of X. This system, which promotes a similar function in the social network previously known as Twitter, is open source and It is available in githubwhich allows anyone to audit and reuse it. However, the adoption of the X algorithm by goal is not a definitive step. The company plans to take it as a basis for developing its own version. “As our own version develops, we may explore different or tight algorithms to support the way in which the community notes are classified and described.” No scope penalty. Goal ensures that its new system against misinformation will not punish the distribution of publications. Unlike the old fact verifiers program, where the marked contents could lose visibility, the community notes will only add context without affecting who can see them or how far they can go. But the notes will not appear yet. As we have said, the community notes system will begin to take its first steps on Facebook, Instagram and Threads this month, but users will not see them yet. It is an evaluation phase. The idea is that the deployment occurs has taken the first step to dismantle its external verification system. And he has done it with the X algorithm when the company is sure it works as a wait. During this period, they plan to make more adjustments and improve the system. Old system verification labels will continue to appear in the United States until the new system begins to deploy generalized in that country. And what will happen in Spain? Although the Meta External Verification Program began in 2016, did not land in Spain until 2019. In the country, the multinational continues to have verifiers such as Newtral, Maldita.es and AFP, which continue with their usual work. Meta ensures that its intention is to expand community notes globally, but it remains to be seen how possible challenges related to European legislation.

In his efforts to cut and fire workers in the US, Elon Musk has gone one step further: Italy

In February an unprecedented event occurred in the United States. The government efficiency department (Doge) led by Elon Musk in the Trump administration, the same person in charge of carry out those “cuts” that he has staged with the chainsier that Milei gave him, fired 350 officials of the energy department. He had gone his hand so much that he had to rectify to recover specialists in the assembly of nuclear eyelets. The chainsaw Musk has just transferred borders, but he has met Italy. The controversy in Aviano. It is public and notorious. Elon Musk, known today for his aggressive management and reduction of cost management, has just generated A new international controversy After imposing its productivity control system at the American Avian Air Base, in northern Italy. An email Aimed at Italian employees The base required that they report five weekly achievements, under threat of dismissal if they did not. This type of measure, already implemented in the United States, has collided fully with the Italian labor system, which guarantees strong protections and rights to its workers. The incident has caused an immediate reaction of the unions, the Italian government and public opinion, triggering a confrontation between the business model of Musk and the labor laws of the European nation. Musk mail and surprise. The message in question was sent to Aviano Base Employees that work in areas such as restoration, maintenance and logistics, essential services for the functioning of US military facilities in Italy. Although the order was supposed to be aimed at Washington employees, the mail Italian workers were forwardedwhich generated confusion and alarm. As we said, in Italy the right to work It is constitutionally protected And contracts offer some job stability, so Musk’s demand has been seen as an unacceptable interference. I told New York Times Roberto del Savio, union representative of the employees of the base, his immediate rejection of the directive: “We are in Italy. Here are precise rules, and thank God for it. ” Not just that. The rejection was not limited only to the workers of Aviano. In total, around 4,000 Italian civil employees They work in US bases in the country, serving 15,000 American soldiers and guaranteeing the operation of facilities that operate as small American peoples on European soil. @alberico_dip Anch was not vero io gli risponderei così ♬ Original Suone – 😂 Alberico di Pasquale 😂 The Italian labor system. The European country, as we said, has one of the most protected labor systems in Europe. Of course, with his “Peros”, but the laws They guarantee job stabilityunionization and rights that are difficult to modify, especially in the public sector. Unlike the United States, where companies can fire employees with relative ease, in Italy the dismissals are more complicated and require solid legal justifications. In this regard, Pierpaolo Bombardieri explainedgeneral secretary of the UIL union, which Musk’s mail is “unacceptable and aberrant.” In fact and given the outrage generated, the unions sent letters to the Italian government and the United States embassy demanding clarifications about whether these types of measures could affect Italian workers of the US bases in the country. What do the bases say. Current norms establish that Italian civilian employees are only obliged to respond to instructions if they come directly from the United States government, not if they are tested emails. However, it is not clear if the Department of Defense plans to extend these productivity control practices to local workers. Reactions in Italy. The episode has not only generated indignation in the unions, but also became A mockery theme In the nation. The rigidity of the Italian labor system is seen by some as a guarantee of stability, but by others as an obstacle to modernization. For example, right -wing journalist and commentator Nicola Porro wrote on his blog: “Italy would also need Musk’s ax.” In social networks, a video of the content creator was popularized Alberico di Pasqualewho simulated how an Italian worker would respond to Musk’s mail. Of course, The video went viral Quickly, humorously reflecting many Italians about their work culture and the clash with the vision of extreme productivity of Musk. Musk, Trump and uncertainty. Beyond the punctual controversy in Aviano, the incident occurs in a context of uncertainty about the commitment of the United States with its military bases in Europe. Trump has insisted that European countries They must assume greater costs In his own defense, which has generated speculation about possible cuts in military bases such as Aviano. In fact, in parallel to the controversy, the US government froze credit cards Used by Italian employees of Aviano to buy equipment and stopped new hiring. Decisions that have increased concern among workers, who fear that the pressure to reduce costs will end up affecting their jobs. Hence, the words of Emilio Fargnoli, union representative, seem to be the voice of the majority: “Musk can do what he wants in the United States. If there are happy with that, perfect. But here, no. “ Image | Nathan Hughes, Gage Skidmore In Xataka | Elon Musk fired hundreds of employees and now he has to hire them again: they were experts in nuclear weapons In Xataka | 131 Microsoft Excel templates to organize everything

The European Central Bank has been fighting for five years to literally create a “European Bizum”. Now has taken a key step

Europe wants to have its own instant payments system. That would allow the dependence of the great market leaders, Visa and Mastercard, and strengthened the European financial ecosystem. And the plan begins to take shape with Bizum as a great protagonist. Bizum is looking for allies. As they point out In Electomistthe idea is to unify the payment systems that are currently working in the various countries of the European Union. Bizum, protagonist in Spain, has its twin schemes with Bancomat Pay in Italy and Sibs in Portugal. All of them now pose to be interconnected with a specially relevant reference. Wero, the German Bizum. The Instant Payment System It has been since summer 2024 being the great alternative in France (where they used Paylib), Germany (Giropay), Belgium and Luxembourg (Payconiq) and Holland (ideal). This project of the European Payments Initiative (EPI) is taking shape, and it can precisely be the other great component of that fusion of instant payment systems in Europe. The ECB wants a European bizum. Sources close to negotiations indicate that the project is on the table. To get ahead, we would have that giant of the instant payments that for years has tried to boost the European Central Bank (ECB). A long -sought project. Five years ago the European Commission He started looking that “European bizum” with the launch of the aforementioned EPI. In the project 16 great banks of Spain, Germany, France, Belgium and the Netherlands participated. A year later the figure amounted to 31 entities. The objective, offer a unified payment solution with a payment card and a digital purse. But that has gone through problems. The initiative was promising, but the slowness of its implementation and the excessive budget necessary to achieve this caused several banks to withdraw from the project. As indicated in the economist, the Spanish bank had to contribute 300 million to the initiative, something debatable if we consider that Bizum has existed since 2015 and has a massive acceptance. Spain, Portugal and Italy teach the way. Last year Bizum, Sibs and Bancomat Pay began working on connecting their platforms and making possible instant payments between these countries in the same conditions as to the national scale. It was also the result of the Bizum Union to the European Association of Mobile Payment Systems (EMPSA), which was the consortium of southern Europe. That alliance brings together 43 million users, of which 28 belong to the Spanish system. Germany, France and Belgium were looking for something similar. Something similar happened with the EPI and Wero, which interconnected the mobile payment systems of Germany, France or Belgium and wanted to become the European Payment System. Now both consortiums have approached positions and according to the sources mentioned there are options to end working on an interconnection of all systems. This looks good. It is not clear if the conversations will end with a single European system – will Bizum be called? Wero? – Or if at the moment we will work on that interconnection of all these applications separately, but of course these efforts can be the principle of something great and important for the European panorama of instant payments. It is already known. Union is strength. In Xataka | The arrival of the digital euro is inevitable: let’s say goodbye to anonymity

On their way to mass implementation, Perovskita cells have taken another step: 10 times more resistant

Perovskita’s solar cells are known for their lightness, managing to develop Ultrafin panels with different applications, such as The candle of a ship. However, the stability of this type of cell meant a challenge for its commercial viability. Now, a group of researchers has managed to extend the useful life of a Perovskita solar cell. Short. Scientists from the University of Surrey They have developed Perovskita solar cells that, by incorporating aluminum oxide nanoparticles, improve both durability and efficiency. Thanks to this finding, cells will be more resistant for large -scale application. The problem to be solved. Here you have to make an important comparison, because the solar cells of the study are of Perovskita that are more efficient and economical than those of silicon, so it has been one of the main objectives of the researchers for their commercial implementation. However, the main challenge was that cells They suffered iodine leakscausing the structure to react chemically reducing its performance. In addition, factors such as humidity, heat and oxygen accelerate this process. The investigation. Surrey’s team, together with the United Kingdom physics laboratory and Sheffield University, He has discovered that when integrating aluminum oxide nanoparticles (Al₂O₃) within the Perovskita layer, iodine can be trapped and prevent it from escaping. This simple but effective approach drastically improves the structural integrity of Perovskita’s solar cells, making them more resistant to weather conditions. The results. Solar cells containing nanoparticles maintained high performance for more than two months (1,530 hours), compared to just 160 hours of Standard Perovskita cells. In this way, the investigation has achieved an increase in the durability of ten times more. The incorporation of these nanoparticles has helped create a more uniform Perovskita structure, which has reduced the defects of the material such as moisture and has improved electrical conductivity. Iodine is not always bad. Unlike this study, iodine can be the result of a solution if the right approach is sought. A study group from the University of Beijing has achieved Integrate iodine into a Perovskita structure. In this approach it has stabilized the material and has avoided the degradation that has historically limited its durability. A great future. In 2009, Perovskita’s solar cells only converted 3% of solar energy into electricity, wasting the remaining 97%. However, Thanks to recent advancesits efficiency has exceeded 25%, increasingly bringing them closer to generalized commercial adoption. This progress highlights the great potential of technology, and with more studies, it is expected to continue increasing, approaching even higher figures and opening new opportunities for solar energy.

Spain has filled Europe with excellent tomatoes that do not know anything. It’s time to step further

The story is known: last year, the reputed French socialist policy Ségolène Royal gave a television interview in BFM.TV in which I accused Spanish tomatoes of being “false bio”to “deceive the consumer” and come to say that they were “surable.” Government, agricultural associations and personalities Like Jose Andrés They went out in Tromba to defend the Spanish product. So and today, the controversy should be to ask ourselves if there is something to learn from all this. But let’s start with the obvious. Spanish tomatoes are excellent. For decades, in fact, Spain has been the international reference of this product, and doing so is not easy. Remember that tomato is the fruit and vegetable culture more valuable What world. Only in 2021 they were consumed in the world More than 189 million of metric tons and represents 31% of all the vegetables that occur in Europe. That is, there is a lot of money in the tomato and there are many countries behind that money. Spain would not have been for years One of the great exporters of tomatoes from the world, nor would it have conquered all European markets, without extremely high quality and standards. Well know in Almería that a small failure It takes you out of the market in a matter of days. The kings of tomato … commercial. In fact, if we go down to detail, Spain nails three main types of best -selling tomatoes internationally: the balls, the Saladette and the cocktail. Within these typologies, the varieties of the Spanish field continue to excel in color, size and useful life. The problem is not that. The problem has never been that. The problem is that we have given Europe (and the rest of the world) just what they wanted: colorful tomatoes, good size and easy to handle “post-recreational.” And we have done it at a good price. That is, we have given them the best possible commercial tomatoes. The problem is that these tomatoes do not know Tomate. And commercial tomatoes lost the taste. In 2017, a team of researchers from the University of Florida led by Harry Klee They analyzed 398 different varieties of tomatoes with the idea of ​​tracing the genetic bases of their organoleptic qualities. His conclusions were that, while the smell-for-the balance of fruits such as banana and strawberry depend on a single volatile compound (or very few), “the tomato needs about 25 different compounds to build its unmistakable organoleptic identity. “ The composition. That are dozens of amino acids, sugars and well -balanced volatile compounds. A chemical balance that on the way to find better colors, sizes and durability, became something very difficult to maintain. And that, in fact, it has not been maintained: it is a common place to say that the tomatoes no longer know tomato, but the investigation He supports it. According to Klee and his team, commercial varieties only have 13 of the 25 volatile compounds that give the smell of tomato. There is life beyond commercial varieties. Faced with these varieties of great views, productivity and durability, we have other types of tomatoes: what is called ‘Heirloom’ (of ‘inheritance’ or ‘family relic’). A tailor drawer to talk about local or regional varieties, with little circulation, whose development process has allowed them to maintain a well-balanced flavor. It is not a miracle. We talk about less productive tomatoes (the plant can ensure more sugar in each fruit) and that, being little resistant to post-harvest handling “, have shorter distribution chains that allow greater maturation in Mata. That is, their technical limitations play against their commercialization, but in favor of their flavor. As is obvious, Spain is full of tomatoes of this type. Not only Barbastro’s pink tomato or Tudela’s ugly, no. The list is endless: the Montgrí de Girona, the Cor de Bou, the Mutxamel of Alicante, the Galician monfortes, the Avoa de Osdo, the tomatoes of the Sierra de la Culebra, the black tomato safe, the Mallorcan Valldemassa and a long etc. . No one in their healthy judgment can bite a well -matured mutxamel and take seriously that Spanish tomatoes do not know anything. I don’t know if Ségolène Royal compared a Spanish commercial tomato with A French Heirloom variety or simply I was doing politicsbut it is true that beyond all The inaccuracies and tone outputsthere is something interesting about what we can reflect as a country. Spain and the tomatoes of the future. In 2022 and for the first time in history, Moroccan tomato sold more than Spanish. And not a little: sold 21.3%. Gradually, the United Kingdom and especially France have begun to replace Spanish tomatoes for those from the other side of the Strait. There are many reasons behind this, but few solutions. And, although Spain is still very strong in the rest of Europe and is opening a hole in the North American market, the ‘sorpasso’ is a warning to navigators. The regulatory advantage of belonging to the EU is getting rid And what we started to see is an agricultural giant with mud feet. And it’s time to take it seriously. We know that to continue being an international reference in the sector we will have to launch one of the “agricultural transformations” more important in history, the question is whether we take advantage of our competitive advantage to lead these changes or engage in an international war that We don’t seem like we can win.

Kazakhstan is one of the world’s greatest uranium producers. Now has taken another step: its first nuclear power plant

In the geopolitical board of energy, the domain is not only measured in oil barrels or cubic meters of gas. There is a resource, silent but powerful, which is redefining the current panorama: uranium. While some countries look desperately reduce your energy dependenceothers have understood that true power lies in controlling not only the raw material, but the entire nuclear cycle. Russia has already taken the lead with A dozen centrals Under construction, but now Its largest supplier He also wants to become a strategic actor. New actor. Kazakhstan has decided to accelerate its nuclear development to address its growing shortage of energy. The government has approved the construction of Your first nuclear power plant and a plan to expand its nuclear industry. A referendum in October 2024 showed that 70% Voters support the construction of nuclear plants. This first nuclear power plant will be located in the village of ülken, in the Almath region. The government intends to build at least three more floors to make the most of its resources. Currently, feasibility studies and negotiations with international suppliers are being carried out to determine the technical and financial details of the project. The main financing will come from a Russian government loan with subsidies, and Samruk Energo It will lead the negotiations to guarantee cost efficiency. Energy shortage. The Kazakh country wants to reduce its energy dependence and face a growing internal demand. Despite being one of the countries with greater uranium reservesIt does not have an operational nuclear power plant since 1999. However, it manufactures pumping equipment for nuclear plants and seeks to expand the national production of reactor components and energy equipment. This strategy is aligned with the objectives of carbon neutrality and industrial modernization. An energy cluster. The government seeks to develop a “Nuclear cluster” that not only includes the energy plant, but also the local production of nuclear fuel. To do this, he has formed alliances with China and France. In addition, for nuclear reactors, it will have technology suppliers such as the Galo and South Korean country. The central will probably have a capacity of at least 3 GW, and more plants will be built in the future. Kazakhstan will also strengthen its electrical networks and better connect the western region with the national system. So what happens to Russia? The Kremlin remains an important actor in the global nuclear sector and has supplied Kazakhstan nuclear technology in the past. However, within the country, the concern that an agreement with Rosatom (the Russian nuclear agency) generates excessive dependence, both in technological and financial terms. The opposition has expressed fears that Russia use nuclear energy as an instrument of geopolitical influence. Problems in the past. Nuclear energy in the country has constituted a delicate issue due to the effects of Soviet nuclear tests in the region of Semipalatinsk. For that reason, as indicated Professor Kashi Nath Pandita, concerns about security and lack of transparency in regulatory processes are brought on the path of progress. Forecasts The project can be finished in the next decade, but advance it. However, the country still faces different challenges such as public distrust, environmental concerns and the need to choose a technological partner without compromising its independence. In the long term, this expansion could position Kazakhstan as an energy leader in Central Asia, reducing its vulnerability to regional energy instability and strengthening its presence in global competition for the control of energy resources.
