The science behind one of the AI pillars has an origin as unexpected as unknown: pigeons pecking for food

by

Imagine a missile guided by a dove. It sounds absurd, but it happened in the middle of war: someone proposed to train them to Picute the target from a screen and thus redirect the projectile. The system was never usedbut left something more powerful than the anecdote: A way of learning based on proof, error and reward. The comparison helps to understand logic, but it is not literal: today there are no birds in algorithms; What is maintained is the idea of strengthening behaviors through signals. That logic, simple and direct, is the one that many artificial intelligence models follow. What was previously an answer conditioned by food, is now a score, a preference or human indication that the model learns to pursue. The test and reinforcement mechanism was not lost over time. In the 1940s and 1950s, the American psychologist Burrhus Frederic Skinner formalized that idea with his theory of “operant conditioning”: A behavior increases its probability of repeating itself if its consequences are positive. Although behaviorism was displaced by approaches focused on mental processes, its logic found a new field in computer science. Since the end of the seventies and, above all, in the eighties and ninety, Richard Sutton and Andrew Barto applied it to the design of artificial agents capable of acting, receiving a signal and adjust ‘Reinforcement Learning: An Introduction’. As Mit Technology Review points outthe idea of molding behaviors without resorting to fixed rules became a useful tool to teach machines. From the 1980s, reinforcement learning began to be implemented in algorithms that explore simulated environments, fail, receive feedback and try again. They do not follow human instructions step by step: learn based on the result. This approach proved to be especially effective in tasks with clear objectives, such as games. And it was there that he gave one of his most visible jumps. Alphago’s story marked a before and after in artificial intelligence. In March 2016, he beat South Korean Lee Sedol 4-1 in a series of Go games. He succeeded by combining supervised learning of human games and reinforcement learning. A year later, Deepmind was one step further with Alphago Zero. Instead of training with human data, he started from scratch and learned playing against himself: each victory reinforced his strategy, each defeat the corregía. In 40 days he surpassed not only the human championbut also to all the previous versions of Alphago himself. Today, reinforcement learning is not only used in games; It is also used to refine the models behind services such as Chatgpt. The OpenAI system incorporates a technique known as Reinforcement learning with human feedback (RLHF): people compare model responses and those preferences become a signal that guides their evolution. According to Openai, this phase seeks to align the behavior of the model with the user’s intention. It does not learn explicit rules, but patterns that maximize the reward, that is, what receives better assessments. Reinforcement works, but it doesn’t work for everything. Its effectiveness depends on the signal being well defined and represents the objective well. If it is confused or poorly designed, andThe system can adopt ineffective or even problematic strategies. This has fed a scientific debate. Some biologists have indicated the paradox: Association learning is considered limited to animals, but is celebrated in AI when it produces advanced results. It is no accident that great technology have adopted this approach. More than 80 years after that experiment with pigeons, their pecks are still present in the technology we use every day.

Ryanair is abandoning small airports in France. There is an unexpected beneficiary: a Spanish airline

by

France is the queen of world tourism. Spain is close, but the neighboring country moved In 2024 almost 90 million visitors. A good part of them depend on the plane to arrive, and the problem is that they will soon pay more money to leave. The reason? A “solidarity tax”. And Ryanair has not been funny. So little that will leave some routes in winter. On the other side of the door, ready to collect the witness, was a Spanish airline. Volotea. Taxes. The trigger is the TSBA. This is the abbreviation of ‘Taxe de Solidarité Sur Les Billets d’Avion’, a tax applied in France to the tickets. It is the French authorities that set the amount of tax with the aim of financing international aid programs or to promote ecological measures. A few months ago, that tax experienced an increase of 180% and, although It depends on the flightdistance and plane, in a Economic flight Within France or Europe, the rate went from 2.66 euros to 9.5 euros. Other countries have other rates and in Spain, for example, there is one that applies to the use of infrastructure, security, shipping and other services that will rise about 68 cents per passenger as of March 1, 2026. It is a 6.5%rise, much lower than French. But well, as we say, Italy, Germany or Netherlands also have their rates. Leave. Ryanair comes into play here. The airline, the largest in Europe by fleet, considers that they are excessive and threatened to state that the increase will make many routes unfeasible. In a nutshell: trips to regional airports to small and medium -sized cities will not be so profitable by reducing the margins of these Airlines ‘Low Cost’ and, therefore, it would cease to make sense to keep them. And so it has been. As we read in Radar TravelRyanair will completely retire from Strasbourg, Brive-La-Gaillarde and Bergerac airports from this winter. In total, it will cut 25 routes and 750,000 seats on those dates, reducing its operations in France by 13%. Proper names. The consequences are devastating for the affected cities: Brive loses routes such as London-Stansted. Strasbourg loses links with Porto and Agadir. Bergerac will lose 33% of the activity, which can even touch the airport. They are the most affected, but other larger airports such as those of Toulouse, Marseille or Beauvais in Paris will also have activity cuts. “Unless the government eliminates this unfair air tax, Ryanair’s capacity and investment in France will inevitably redirect to more competitive European markets such as Sweden, Hungary or part of Italy, where governments are eliminating air taxes to stimulate traffic, tourism, employment and economic recovery,” Comment The CCO of Ryanair, Jason McGuinness. Volotea. This decision has resonated at the Volotea offices, a low -cost Spanish airline that bases its business on connecting small and medium -sized cities in Europe. They are those that do not usually cover the big companies, with 420 Routes in 2025reaching up to 100 cities in 18 European countries. Two names that we have already commented and that covers volotea are those of Marseille and Toulouse. And, how we read in Hosteltur And that Volotea itself collects in its press section, the withdrawal of Ryanair leaves room for the Spanish to stay with the connections of Strasbourg with Agadir (Morocco) and Porto, with the intention of creating 70 jobs to operate. “I don’t want money”. Thus, from this new pulse of Ryanair to the authorities of a country, the Spanish company benefits. And it is a sum and continues in a particular battle that Ryanair undertakes when the margins are at stake, such as when the controversial CEO of the company, Michael O’Learyconfirmed that aspires that passengers fly without suitcaseseven when of the 13,400 million euros that entered 2024, 4,299 million come from Extras how to fly with a cabin suitcase or choose a seat.

Spring rains have generated an unexpected problem to Spanish farmers: Cereal too cheap

by

Cereal cultivation continues to live convulsive times. Like many other crops, cereals suffered the consequences of last droughta drought that came to put the sector against the sector in 2023, transforming the dream of become the barn of Europe In a bitter awakening. Prices fall. Now the lament of the sector comes from another place: prices, collapsed after the recovery of the offer, a consequence of the recovery of production. A recovery that could hardly have occurred without a hydrological year as favorable as that of 2024-25. However, it never rains to everyone’s taste. From León. Perhaps the best example we find In the Leon Lonja. There last week the price of cereals such as wheat, rye or oatmeal saw slight falls in prices. The problem is more pressing if we consider the price two years ago: € 247/t. This implies that, in the last two years the price of cereal has dropped by more than 20%. Oats, in free fall. Another striking fall It has been oatmeal: if two years ago the price of this cereal was in the € 285/t, the price has dropped from then to € 136/t, 52.3% less. A year ago the price was € 183/t, which implies that only this year the drop in the price has been around 26%. Corn, the exception. Corn is the only cereal that seems to escape this trend. Their prices remained stable in fish markets such as León, while getting up in others, Like Salamanca. Lost opportunity A fall to which the sector has responded with pessimism since in the province the harvest is already practically finished. Farmers point out that these prices barely serve costs and They talk about “Lost Opportunity” When referring to this campaign. Supply and demand. The sector indicates the origin of the problem in a simple equation, that of supply and demand. Prices have fallen significantly since 2023, when the drought put in the middle of the agricultural sector against the ropes: the absence of rains and restrictions limited agricultural production. Now, production has recovered, but the problems continue. The increase in supply has not been equated with greater demand, which has facilitated a collapse in prices. To the precarious situation other external factors must be added, such as changes in international trade patterns, among which They are included The new tariff war between the United States and Europe, a conflict still to be resolved that adds firewood to the fire in the form of uncertainty.

The hydrographic basin that is most suffering from drought is an unexpected one: Galicia’s

by

Summer It is taking its toll To the Spanish reservoirs and, despite the fact that the hydrographic basins maintain good health, some of these areas have seen how their reserves have markedly diminish. This has led to repeat an already familiar scenario: consumption restrictions. First restrictions. Galicia is an example of this. In this community there have been several councilsespecially in those located south of Pontevedra, who have announced restrictions to the use of water. The implemented measures differ as the case reported the Chain ser. The problem affects more areas of the Northwest, not just Galicia. As reported The newspaper Commercesome municipalities and parishes in Asturias have already announced the implementation of measures of this type to force water savings. These measures, explains the local press, affect only the “great consumption”, such as swimming pools and vehicle washing, similar to the previous ones. The restrictions have even reached some municipalities in the province of León, especially in the Laciana region, also reported the local press. The town hall of Villablino has been the one who has given the alarm, announcing restrictions on domestic use. The Galician basins. The data published this week on the Stadium of the Reservoirs confirm a worrying trend in a good part of the basins of the northwest of the Peninsula. This is especially notorious in The basins of the coast of Galicia The only basin north of Júcar below 60 % of its capacity, with its swamps full of 58.5% on average (400 hm³ in total). At the end of May, these reservoirs exceeded 80% of its capacity. Question of size? There are two factors that explain this rapid descent. The first is a hard summer: the month of June was an extremely warm month in Spain, Also dry (Galicia being one of the driest areas within the Peninsula). Although the month of July was somewhat more wet, most of the rainfall concentrated on the west peninsular. The second is that we are talking about a small, the sixth smaller sixth basin, with a capacity of 490 hm³, a small fraction of the capacity of neighboring basins such as that of the Miño-Sil (3,030 hm³) or the Duero (7,602 hm³). Lower size implies greater variability, less capacity to absorb Shocks and changes. Below 2024. Although the situation is not so striking in the rest of Galician basins, there is a detail that all the Northwest basins share (Western Cantabrian, Duero, Galician Basins and Miño-Sil): they all have less water than they had last year by these dates. The difference is more pronounced in the small basins: the reservoirs of the Galician coast kept 483 hm³ this week, which implies a drop of 17.2%, while those of the Western Cantabrian They have passed from 430 to 357 hm³, almost 17% less. In contrast, that of the Miño-Sil It went from 2,506 to 2,403 (4.1% less), and The Duero From 5,993 to 5,766 hm³ (3.8% less). On average, the Peninsular basins They have 14.9% more water than last year by these same dates. Summer remains ahead. There are still almost two months left for the end of the hydrological year. This change of the year is between the months of September and October, at which time autumn precipitations usually change the descendant trend in the reserve of the summer months.

In Europe, gas and disused coal plants have unexpected suitors: technology companies

by

The climatic commitments that It has acquired Europe They have condemned in the short or medium term the future of gas and coal power plants disseminated by the old continent. Many of them no longer serve, but, surprisingly, the rise of the artificial intelligence (AI) has the ability to save them. This does not mean at all that they will burn gas and coal again; The option on the table is to convert them in data centers. Microsoft and Amazon are, According to Reuterstwo of the large technology companies that are interested in transforming these old power plants into modern data centers equipped to the last one. In fact, its managers are already negotiating with the French energy company Engie, the German RWE and the Italian in the possibility of using their facilities for this purpose. For energy companies this option is very attractive because it allows them to kill two birds. On the one hand, the transformation of their old electric power plants into data centers guarantees them in income with which they did not count so far. And, in addition, the energy companies that I have mentioned in the previous paragraph and some others are negotiating with the technology companies the possibility of give them the supply of electricity that require your data centers. A priori seems like a fissure plan. An agreement in which everyone wins “You have all the necessary pieces, such as water infrastructure and heat recovery.” This Bobby Hollis statementVice President of Energy in Microsoft, repairs something very important: the old gas and coal centrals that are no longer operational have the water supply and the heat management infrastructure that data centers need. Presumably it will not be necessary to undertake a large adaptation to transform these facilities into operational data centers. Agility when putting up these data centers and moderation of costs is what makes them so attractive to large technology On the other hand, Lindsay Mcquade, director of Energy for the EMEA area (Europe, Middle East and Africa) at Amazon, Trust in that the permits that technology companies need to operate these converted data centers are available long before the new facilities. After all, most of Infrastructure are already installed In these buildings from the beginning. In fact, agility when pointing out these data centers and moderation of start -up costs is what makes them so attractive to large technological ones. In Europe and the United Kingdom since 2005 they have closed no less than 190 coal and lignite centralsand another 153 will follow this same path before the year 2038. It is evident that the possibility of reusing all these buildings transforming them into data centers for AI is very attractive. However, there is a challenge that is not yet resolved and that can condition this plan. It is not clear that the electrical infrastructure of some countries is capable of delivering The energy required by these facilities without previously undertaking a large -scale development. In this scenario renewable energies and nuclear will have the last word.

The four -day workday has found an unexpected ally in Moscow: the Ukraine War

by

The conflict in Ukraine continues to reconfigure not only Geopolitics and the European Budgetsbut it will also change the working day of thousands of Russian workers. Avtovaz, one of Russia’s biggest car manufacturers, has announced that it will apply the four -day work week As of September. According to The published by Reutersthis is not a measure oriented to Improve productivity or reduce the stress levels of its workers, but adopts this measure in the middle of a strong fall in vehicle sales, a crisis of consumption due to the wear of the invasion of Ukraine and a growing pressure of exports of Chinese cars. Russia does not sell cars. Avtovaz, is the manufacturer of the acquaintances Lada. After the first months of the Ukraine War, the Russian Automobile Industry lived a brief increase in defense expense and state subsidies. However, according to data from Reutersthis situation has begun to revert quickly. Avtovaz explained through a statement sent to Russian media that their sales fell 25% in the first semester, with only 155,481 units sold, and estimates that this will be the tendency for the entire source year. Avtovaz is not the only one to consider the four -day work week as a measure for shock the crisis of the sector. According to The local pressthe Russian manufacturer Gaz (Gorkovski Avtomobilny Zavod) will also apply the four -day week on his Gorki plant, for the same reasons that Avtovaz argued. Russia’s own Minister of Economy, Maxim Reschetnikov, He warned in June that the country “is on the verge of entering recession.” Avtovaz, as a reflection of this crisis, wants to use the letter of reduction of the work week as a way of maintaining employment without increasing the number of layoffs in difficult times. No money to make them or to buy them. According to published The Moscow Times“The final decision on the introduction of a reduced work week of four days will be taken based on the results of an analysis of market trends and economic factors, including the level of the key interest rate and the availability of credit products,” said the manufacturer’s statement. The main reason that has uncontrolled this crisis (in addition to being a derivative of the conflict in Ukraine), has been the increase in interest rates, which slows so much production Like consumption. “We are talking about a high key rate and more severe demands by the regulator for those facilitating cars loans,” Avtovaz explained in his statement collected. The impact of high types not only feels Avtovaz. The Russian giant of the Seversal Steel, pointed outthat “the high basic rate and low prices” were responsible for a 55% drop in their benefits in the second quarter of the source year. That is, as I know money is expensivecompanies lose profitability and citizens purchasing power to buy cars that are manufactured, generating a chain effect that complicates economic recovery. Chinese cars are unstoppable. To the already complicated economic crisis of the automobile sector worldwide, the massive emergence of imported cars from China is added, which sell their products at such low prices that Avtovaz directly accuses a “price dumping policy.” According to company sources these marches, mostly Chinese, are increasing the market pressure with very small prices to give out more than 400,000 cars that these importers have stored in their dealers and have not yet sold. Gaz starts already, Avtovaz leaves it for September. Russian Fuentes assure that Gorki de Gaz’s factory will implement the four -day work week immediately. From July 21 to August 3, the employees of this plant will enjoy their vacations normally. During this period, several divisions of the plant will continue to operate according to their work schedule. Once they finish, the four -day work week will be implemented at least until the end of August. Avtovaz indicates that it is still analyzing the way to implement the measure, so it will enter into force for September in the factory that the company has in Togliatti, in which one in 20 inhabitants of this city works. You know what it is to work four days. Although it is not done for the reasons for productivity and well -being improvement That this model of day is usually applied, this is not the first time that Avtovaz resorts to the reduced working day to deal with a crisis. In 2022, just after the imposition of First international sanctions To Russia for the invasion of Ukraine, the company implemented a four -day work week for three months. During that same year, the sales of its flagship model, the Lada, fell 48.2%, until 174,688 units, according to data publishedby The New Voice of Ukraine. On that occasion, four -day work week served to maintain a certain level of production In an adverse scenario. Today, three years later, economic conditions remain equally complicated, so companies re -apply the same recipe.

Andalusia has become hostile land for avocado. So an unexpected region is taking over: Galicia

by

In Spain, avocado has ceased to be an exotic food to become the new king of the shopping basket. Its demand grows without stopping: only in 2023, tropical fruits became the most consumed in the country, surpassing even the citrus of life. But while the surface dedicated to avocado cultivation in Spain is already 24,000 hectares –With Andalusia at the head-, the south begins to resent. Missing water. There are plenty of extreme temperatures. And the producers look for alternatives in the north and there Galicia enters. A new tropical map. The image of an avocado is not associated, precisely, the wet green of the peninsular northwest. But data and real experiences begin to tell another story. Because in Galicia the avocado not only grows: it is standing strongly. As he collects A report from the voice of Galiciain the province of Pontevedra there were already at least seven hectares cultivated in 2022, and everything indicates that this figure has been doubled since then. “It is a very interesting production that is already being introduced into many Galician cooperatives,” says Higinio Mougán, director of Agaca, the Galician Association of Agrifood Cooperatives. Attracted by high market prices – and for a demand that does not stop growing – Galician farmers such as those of the Horsal Cooperative are already betting on this crop. However, they do it cautiously since not everything is as easy as planting and waiting to collect. But is it land of avocados? In theory, yes. Galicia presents a soft climate, without prolonged frost and with generous rainfall. Characteristics that, like The CSIC Iñaki Hormaza researcher ensures For the Galician medium, “they look more like the climate originally from avocado than that of some areas of Andalusia.” Which does not mean that there are no risks. Temperatures of more than 35º in summer, strong coastal winds, floodable floors or the possibility of unexpected frosts remain limiting factors. “It is not a crop to launch without prior study,” says Pablo Porto, coach of Vivaz Plant, a company that has developed plantations at Baixo Miño. The terrain must have good drainage, be protected from the wind and have deep and aerated soils. And that without talking about the productivity challenges – less than 1% of the flowers bear fruit – or post -harvest, which alerts the damage for forced collection on temporary days. There is evidence that it works. 300 kilometers east, in Asturias, The story of Ángel Sordo and his centenary avocado In Porrúa it is almost legend. Planted in 1906, this tree is still standing more than a century later and is considered the oldest in Europe. “Its cup reaches 30 meters in diameter,” a living emblem of what could be a new agricultural border. Inspired by this legacy, entrepreneurs such as Andrés Ibarra founded Aguacastur to explore the potential of avocado in the Cantabrian. His discovery was revealing: thousands of scattered trees, some with up to four flowers per year. And no, the cold did not kill them. Thanks to environmental humidity, even -5º temperatures did not cause severe damage. “It is a matter of time that the cultivation of avocados in the north becomes a reality,” said Ibarra. A change that accelerates as the South loses viability. A northern axarchy. As my partner explainedthe comparison is not accidental. The Malaga Axarchy has been the avocado mecca in Spain for decades. But droughts, overexploitation of the vineyuela aquifer and heat waves are changing the script. Is the north – with its water, its temperate climate and its lower urban pressure – the future of tropical fruit in Spain? It would not be the first time. Galicia was the land of Olivos in the past and nobody knows well why it ceased to be. And now, what? The interest is there. Plantations grow. Cooperatives are organized. But the Galician avocado path – like that of every crop that ventures in new lands – will not be free of obstacles. Green gold has arrived in Galicia. And this time, it seems that it has come to stay. Image | Unspash and Unspash Xataka | Very few countries in the world are dedicated to the industrial production of avocados. Now an unexpected one has joined: Japan

EU’s new agricultural strategy begins in an unexpected place: in the school dining room

by

The market share of fruit and vegetables imported has grown up in a sustained way In the last years of countries outside the EU. Meanwhile, local producers see how their margins narrow before a competition with other rules. Faced with this reality, the European Commission It raises a turn in one of its most daily policies: That schools prioritize foods of community origin in their menus. A discreet measure in appearance, but that points directly to the heart of the European agricultural model. A proposal of Brussels. All the fruit, vegetables and milk that reaches school canteens from EU countries will have to be local products. The proposal, presented last week, directly affects the European school program in force since 2017which seeks to promote healthy eating habits from nursery to high school. According to the draft to which Financial Times has had accessthe new text includes an explicit clause to favor “Made in Europe” products, not only for nutritional reasons, but as part of a broader strategy of impulse to community production. More than health. On the one hand, the initiative is part of a protectionist tendency that has already reached other key sectors such as defense, energy or critical raw materials. On the other, it is part of the debate on the future of common agricultural policy (PAC), one of the key pieces of the European budget. According to El Confidencial reportthe reform of the multiannual financial framework (2028–2034), endowed with two billion euros, cuts the PAC in favor of items such as defense, which has caused strong criticisms of the agricultural sector. Associations of Spanish farmers have already protested in Brussels against cuts that consider “a conviction” for the field. Concern is not only economical, but also structural. The Commission recognizes, in the document itself, that there is a growing imbalance in the food chain that especially affects primary producers. In the words of the text: “The unfair distribution of income, risks and cost burden disproportionately affect the agricultural sector.” Adaptation of the new standard. The new approach seeks to adapt the current school program of the PAC to the current demands. According to the draft filtered by Financial Times and confirmed by the official website of the Commissionproducts of community origin will be prioritized, with low climatic footprint, certified as ecological, sustainably packaged or from small local farms. In addition, those products rich in added sugars and saturated fats will be excluded from the plan. A community official cited by FT Thus summed up the philosophy of the measure: “It is good that the children know that this apple comes from a tree five kilometers from their home.” Currently, 17 Member States already apply criteria for local or regional preference in their school programs, according to the commission itself. The intention is to harmonize this practice at European level and reinforce it. The structural problem. The school reform arrives at an especially sensitive moment. Morocco has established itself as one of the main suppliers of EU fruits and vegetables, displacing in some cases the European product. According to An article by El Economistathe community import of Moroccan fruits and vegetables grew by 14% in the first quarter of 2025. A commitment to food sovereignty. Although the school proposal may seem secondary in economic terms, it is part of a broader paradigm change. As Financial Times remembersBrussels has begun to introduce “Made in Europe” clauses in strategic areas such as defense, state aid to the green sector and now also in the agri -food system. The objective is not to close borders, but to establish fairer reciprocity conditions and reinforce sectors considered strategic for the stability of the continent. Among them, food. According to the commissionguaranteeing access to safe, affordable and quality foods is one of the pillars of the European project, together with the defense of the rural economy. A difficult bet. Beyond the food debate, what is at stake is a definition of economic, commercial and social model for the future of Europe. In an era of growing global protectionism, the European Commission gives clear signals: from defense to school breakfast, the “made in Europe” wants to impose as a norm. But in the attempt to protect the European farmer, Brussels site delicate land, where commercial tensions and market realities are not always so easy to digest.

The most unexpected object has become the last battlefield of Catalan independence for a detail: the letter e

by

A letter. The E. thus, in capital letters. And a fine. Capital for some if we consider that it is about paying 200 euros for covering a letter. Because that is the sanction that those who cover in Catalonia are receiving the letter E of the registration of their cars. The same that identifies the plaque with Spain. A lyric. And what lyric is it? The E. of “Spain”, “State” and “confrontation”, to give only some examples. At least for those who consider that this letter in their enrollment is an act of submission to the Spanish State and, therefore, is a cause for political confrontation. That letter that some Catalan independence disappears from their tuition to replace it with the CAT letters, next to a SENYERAas a political claim or small subversive act before what they consider the submission of Spain in the region. It is not new. The confidential collects the return of this way of acting by some Catalan independence. But this act of protest is not much less new. At the end of 2024a Catalan was fined for this reason, when considering the Mossos d’Esquadra that had manipulated the registration, which is considered a serious infraction that entails a sanction of 200 euros. But these attempts to replace the license plates either since then. Already in the last decade You can find some publications that point out this way of acting by some drivers. In some yes the European Union flag was maintained. However, it has been in the last two and three years in which the most noise has been generated. The Galician case. But it has been in the last three years when the phenomenon has taken special relevance. In 2024 a driver complained in social networks of having received the aforementioned fine. In the answers there were those who assured that carrying the CAT on the registration was not illegal. The origin must be found in Galicia. There, Bieito Lobeira, Secretary of Organization of the Galician Independence Party BNG, was fined for covering the E of Spain by a GZ in reference to “Galiza”. After various resources, Lobeira won the procedure because it was pointed out that the small modification did not prevent the correct reading of the registration. To this are grabbed those who act in this way, such as David Miñana (ANC leader) either Jordi Cabré (writer). The matter is slippery because in article 49.4 of the General Vehicle Regulations the following is specified: “It is prohibited that the registration plates be placed, registered or painted ornaments, signs or other characters other than those indicated in Annex XVIII, including advertising inside them (…) It is prohibited that in the anterior and posterior parts of the vehicles they will be placed unauthorized complementary plates or fix or paint marks or distinctive marks or distinctive Difficult readability or may induce confusion with the regulatory characters of the registration plates “ However, in the Traffic Law, where the serious sanctions (200 euros) are reflected, it is specified that the following compliance is sanctioned: “Failure to comply with the obligation of any driver to verify that vehicle registration plates do not present obstacles that prevent or hinder their reading and identification” Lobeira won when the judge understood that he took part in his appeal that the GZ letters did not prevent or hindered the reading and identification of the registration. 25 years. In the newspaper AraThey point out that this fight for the letters of the registration has been living for a quarter of a century. In 2000, the Spanish registration plates changed. They adapted to the obligation to carry the letter E and the flag of the European Union for the identification of a vehicle outside the country of origin. However, the government of José María Aznar also eliminated the references that existed to the regions. Before the year 2000, Spanish registrations were made up of one or two letters that referred to the province, four numbers and two additional letters. Already then The nationalist parties and the United Left complained about the absence of the autonomic badges. Already at that time some media and independence groups they encouraged this little protest actiondistributing stickers to incorporate into registrations. And in Europe? The truth is that in Europe there is a good handful of countries that have maintained regional badges despite having to change the registration plates to adapt to European regulations. In France, in Germany or in Italy Shields, letters or any other badge that specifies the region of origin of a vehicle are maintained.

Scientists launched a cow at the depths of the China Sea. They discovered eight unexpected visitors to the feast

by

The ocean is full of surprises. Sometimes, as happened several years ago in Canada, the enigmas appear floating in the form of human feet adrift. However, in others, most, you have to go down to the depths to try to solve the mysteries. That was precisely what a group of researchers proposed. It all started by throwing the body of a cow. A cow at 1,600 meters. In one of the most unusual marine experiments carried out, a group of scientists He threw a dead cow at 1,629 meters deep in a continental slope of the South China Sea, in front of the Chinese island of Hainan, with the aim of simulating the sinking of a whale and studying the Behavior of scavengers of deep water. What they found surprised even the most experienced researchers: Eight sleepy sharks Pacific (Somniosus pacificus) They appeared in the place, marking the first documented observation of this species in the region. The finding not only unexpectedly expands the distribution map of this elusive shark, but also provides valuable information about its behavior patterns, food hierarchies, physiological adaptations and its possible geographical expansion. An unexpected visitor. Although the Pacific Sleeping Shark is a species with a wide distribution in the north of the Pacific Ocean (from Japan to Alaska and to the south to Baj real extension of its habitatits possible displacement due to climate change or even the existence of a stable population and not yet registered in that region. Food label. The recorded images By underwater cameras they not only confirmed their presence, but revealed unusual behavior for large predators: a kind of Shift systemin which sharks aligned to feed the body, giving the place to other individuals who approached from behind. This type of “Food label”rarely observed in predatory species, suggests that the order in food could be determined by the competitive intensity of each individual, instead of a chaotic struggle for resources, which would indicate a more complex level of social organization that was suspected in these animals. New clues. He study He also documented variations in behavior according to body size. The specimens that exceeded 2.7 meters in length were much more aggressive and direct In the attack on the carrion, while the smallest sharks opted for cautious movements, surrounding the body in circles before approaching. The employer suggests that even in an environment where food is scarce and random opportunities, sleepy sharks could have developed a coexistence strategy with hierarchical ranges that minimize direct conflict. One More Thing. Another remarkable finding was a behavior of Ocular retraction observed during feeding. Since this species lacks Iglestop membrane (The protective “third tab” that other vertebrates such as cats or certain reptiles have), researchers believe that this retraction reflects a Evolutionary adaptation To protect the eyes during bites or struggles, which brings a new data on the defensive physiology of these sharks in their natural environment. The unknown. And more, since the recordings also showed other revealing aspects. Namely: several sharks carried visible parasites In his eyes, identified Like copepodsalthough it was not possible to precisely classify the species. This detail reinforces biological parallelism among the sleeping sharks of the Pacific and their best -known relatives, the Greenland sharkswhich also usually host parasites in their visual organs. Apart from sharks, the experiment attracted a surprising variety of abyssal fauna, such as Caracol fish and numerous amphipodsall attracted by the source of decomposition organic matter. These records confirm that the deep areas of the South China Sea not only house a biodiversity still little documented, but could be more productive of what was believed so far, against the idea that tropical depths are biologically poorer than their polar counterparts. The great unknown. In the background, the presence of these sharks raises a crucial issue: is it a recent expansion of its rank due to global warming, or has it always been part of its habitat and simply had never been observed? It is known that the species has occasionally appeared in such remote regions like Palaos or the Solomon Islandswhich suggests that there could be more southern populations than the scientific literature indicates. However, the “frequent appearance” in the southwest of the China Sea, According to the team itself Researcher led by Han Tian, rather suggests a structural lack of data in a little explored region rather than a recent change in the distribution pattern. In that sense, the experiment with the body of Vaca has not only contributed a specific observation, but has opened a way to review key concepts on the marine biogeography of abyssal species. Know the depths. He find It underlines the usefulness of simple experiments, but carefully designed to obtain data on remote environments, inaccessible already often little understood. The idea of simulating a whale sinking with a cow was not only effective, but proved to be a powerful Ecological magnet able to reveal complex biological interactions. In a context where Climate change and Human activity They are altering ecosystems even at great depth, this type of research is crucial to understand the invisible functioning of the deep ocean. The appearance of eight sleeping sharks where no one was waiting for them, behaving with order, measured aggressiveness and sophisticated adaptive mechanisms, is one more proof that marine depths They keep secrets that we are barely beginning to understand.
