shield

using both is the true “total shield”

by

In recent years we have seen how active cosmetics have put vitamin C at the center of all morning routines. Its fame is justified, but it has brought with it a dangerous myth when it suggests that it can be a solar shield in itself. But the reality is that, although it is true that it provides good additional antioxidant protection against sun damage, under no circumstances does it replace traditional sun protection. Vitamin C. The first concept we must internalize is that vitamin C does not block UV radiation the way a chemical or physical filter does. In fact, it has no measurable sun protection factor on its own. Its true positive effect lies in its antioxidant mechanism, which is responsible for neutralizing free radicals that are generated by UVA, UVB and IRA radiation. By doing this, vitamin C manages to reduce oxidative stress and prevents part of the DNA damage, such as thymine dimers, lesions closely associated with skin cancer. The investigation. Scientific literature has been demonstrating for years that true protection occurs in the synergy of several factors. One of the first studies dates back to 1996, where was demonstrated that vitamin C provides additive protection against UVB damage when combined with a specific sunscreen. But this same study observed that the combination of vitamins C and E was even more protective, and that by adding a UVA filter, much greater protection was obtained. But it does not stop there, since this same team published a second study in 2003 where they saw that the combination of 15% vitamin C and 1% vitamin E applied to the skin for four days managed to multiply approximately by four the antioxidant factor. Infrared light. Given all this, a question that may be obvious is that, if there are already sunscreens with a protection factor SPF 50, why is it necessary to combine it with antioxidants? And the answer lies in the spectrum that conventional creams do not cover. A trial here found that a sunscreen with SPF 30 alone did not protect against infrared radiation A. However, by applying the same protection factor enriched with an antioxidant cocktail, it was possible to significantly reduce the overexpression of factors related to skin photoaging. The consensus. Despite the overwhelming benefits of antioxidants, medical guidelines indicate that there is no evidence that using a vitamin C serum instead of sunscreen is positive. In this case, the American Academy of Dermatology insist in which sunscreen is essential, and antioxidants can be a positive addition, but never a substitute. But in addition, for all this “added protection” to be real, scientific evidence demands two requirements: it must be used in conjunction with a broad-spectrum protector and the vitamin C formulation must be stable, requiring an adequate pH, protection against oxidation and, often, the combination with vitamin E or ferulic acid.

The legal shield of the wolf has been cracking for years. Now the majority of communities in Spain have opened the door to hunting them

by

Maybe not at the level of the housing or corruption, but in the political chronicle of recent years there has been a topic of debate that has exacerbated tempers: the wolf. From 2022 The European and Spanish institutions are immersed in a thorny debate about the degree of protection of the Canis lupuswhether it should be allowed to be hunted or whether it remains vulnerable. The result of this tug of war has not been exactly positive for the species, whose legal shield It has been eroding little by little. Now just received a new setback in Spain, where the majority of communities have made it clear that they don’t look with evil eyes his hunting. What has happened? That the legal status of the wolf has just received a new setback in Spain, where it has become clear (for the umpteenth time) that everything related to the management of the herds is a matter of political dispute. To understand it, we have to go back to last Monday, when the majority of communities and the Ministry of Ecological Transition (Miteco) staged their difference of opinions around a report that, in practice, will influence the really relevant issue: whether or not wolf hunting is allowed in Spain. What exactly was discussed? He sexennial report about the situation of the wolf in Spain. Basically it is a study that shows how the country’s herds evolved between 2019 and 2024 and (importantly) concludes whether or not the current conservation status of the species can be considered ‘favorable’. Said like this, it may not seem like a big deal, but that label (‘favorable’ or ‘unfavorable’) in turn influences whether hunting should be allowed. Furthermore, it is a report required by the European Commission (EC) and which is already a year late: Spain should have sent it before July 31, 2025. Why has it taken so long? Because before the report had to go through the Sectoral Environment Conferencea body in which two parties sit with totally opposite positions: the ministry, in favor of considering the situation of the wolf in Spain as ‘unfavorable’, and therefore in need of high protection; and the majority of autonomous communities, who believe that after years of preservation the species is already in a ‘favorable’ situation. And what did they agree? The positions of each other are so far apart that at Monday’s meeting they were put on the table two reportsboth focused on the wolf but with different conclusions. One was made by Miteco and advocated protecting the herds. The other was presented by the Xunta de Galicia and basically concluded that the herds have increased so much since 2019 that we can now speak of an acceptable level of conservation in the Atlantic and Mediterranean. That last one was (by far) the position that received the most endorsements during the meeting. The autonomous governments of Galicia, Andalusia, Cantabria, La Rioja, Region of Murcia, Valencian Community, Aragon, Canary Islands, Extremadura, Balearic Islands, Madrid, Castilla y León and the autonomous cities of Ceuta and Melilla supported the report that concludes that the situation of the wolf today in Spain is “favorable.” The only votes against were those of the Government and Catalonia, which delegated to Miteco. Basque Country and Castilla-La Mancha they abstained. What does the Government say? The Minister of Ecological Transition, Sara Aagesen, claimed on Tuesday that “technical and scientific rigor” prevailed and recalled that the objective of the report should be to show the state of conservation of the species in the last six years. Along similar lines, Jordi Sargatal, from the Government, judged “without scientific basis or value” the report of the communities led by the PP. Miteco has actually advanced that it will send to the European Commission “all the information” on the subject, which would include both studies. Just a year ago the ministry published a census which concluded that in Spain there are 333 herds, 12% more than in the previous census, carried out between 2012 and 2014. Although this data is positive, the Government itself accompanied it with a footnote: that 12% is still insufficient. “Scientists consider that, to ensure long-term genetic viability, 500 herds must be reached.” What do the communities say? They argue that the species has recovered ground, which would justify opening the door to hunters. “The current status of the book is favorable and there is no scientific basis to justify it having a special protection regime,” argues the Xunta. At stake are not the herds, but their impact, as remember Joaquín A. Pino, counselor of Castilla y León, who recalled that ranchers “suffer recurrently” attacks from wolves. “The management of the species must be based on the reality accredited by the six-year report to also protect extensive livestock farming and rural areas,” insist the regional government before remembering that damage to the primary sector has been increasing by more than 10% annually and, only in Castilla y León, was it recorded last year 4,474 attacks from wolves to livestock farms. The compensation for these damages (6,294 dead cattle) exceeded four million.

the “secret” heat shield of the Ariane 6 parts that Airbus manufactures in Spain

by

We are used to “aerospace” sounding like almost futuristic materials. Titanium, high-strength aluminum, carbon fiber, alloys designed to withstand extreme conditions. The technology industry itself has turned that idea into a sales argument: just remember how some laptops and cell phones They boast of using “aerospace grade” materials.“to convey lightness, resistance and precision. That is why what happened this week during a visit to the Airbus facilities in Getafe caught my attention. In front of one of the pieces, Veronica Villanuevaresponsible for Manufacturing, Assembly, Integration and Testing at Airbus Space Systems in Spain, pointed to a yellowish surface and said it bluntly: “What you see here is yellowish, this is corkit is the thermal insulator that is put on, it is super curious, right?” The phrase had some revelation, but it was not an anecdote for visitors. The cork was there for a very specific reason: a launcher must not only be able to take off, it also has to protect its structures in a very demanding physical environment. In this case, Villanueva was talking about pieces linked to the Ariane 6. We are not talking about an “Airbus rocket”, but rather a European launcher in which ArianeGroup occupies the central role and Airbus participates by manufacturing several structures and key elements. The cork we saw in Getafe shows that space engineering also has very everyday surprises To understand why this detail was so striking, it is worth taking a step back in manufacturing. Before reaching the cork, many of these structures go through a process based on composite materials, especially carbon fiber and fiberglass. Villanueva explained during the tour that the carbon fiber used in the plant arrives as a prepreg material, that is, already mixed with resin. From there, the machines place layers on a mold until the desired geometry is built. Then will come the curing, the inspection and everything necessary to turn that stack into a piece capable of being part of a launcher. The underlying reason is easy to understand: in a launch, every kilo counts long before reaching orbit. A launcher must lift its own structure, its systems and the load it carries, so any weight savings can have significant consequences. The manufacturing manager defended during the tour that composite materials are especially interesting due to their low mass, their tensile strength and their ability to adapt to changes in temperature. The downside is that they are not as simple or as cheap to manufacture as metal. View of the Airbus production area in Getafe, where some structures linked to Ariane 6 incorporate cork as part of their thermal protection That complexity appears as soon as the structure begins to take shape. After taping, the pieces go through an autoclavea type of large pressurized oven where temperature and pressure are controlled so that the resin solidifies and the whole is compacted. Villanueva explained that the process includes a vacuum bag to extract any air that may have remained between the layers, an important detail because possible defects are not always visible from the outside. In a composite structure, what happens on the inside can be as relevant as the exterior geometry. Verónica Villanueva, responsible for Manufacturing, Assembly, Integration and Testing at Airbus Space Systems in Spain And then, after all that chain of carbon fiber, resin, pressure, vacuum and inspection, the least expected material appears again. Cork is applied to certain areas of the structure as a layer of protection against heat, but not in any way. Raúl Medina, head of launchers at Airbus Space Systems Spain, pointed out the pieces during the visit and gave a very specific measurement: “We can go from 2 millimeters to 5 millimeters thick.” On the indicated pieces, that layer moved within a very specific margin. Detail of an Ariane 6 part manufactured by Airbus in Spain. The light areas show the cork applied as thermal protection; the dark ones, areas without that coating The decision is not made by eye either. Medina summed it up with a very graphic phrase: “This in the end is an art. There are thermal engineers who analyze that you will be exposed to more heat and then, depending on that, more thickness, less thickness or areas without cork“On the surface of the piece, this thermal reading translates into areas with more protection, others with less and others where the material from the cork oak is not directly applied. Raúl Medina, head of launchers at Airbus Space Systems Spain. The idea may sound strange, but it does not appear isolated in the European space industry. In another application, ESA explained it with the Qarman CubeSatdesigned to study atmospheric reentry: its nose was made of cork, although not the kind we find in a champagne bottle, but of an adapted aerospace variety. The difference is in the behavior of the material when heated. First it swells, then chars, and finally flakes off, taking some of the unwanted heat with it. Detail of an Ariane 6 part manufactured by Airbus in Spain. The light areas show the cork applied as thermal protection; the dark ones, areas without that coating The supplier’s lead pointed in the same direction. Villanueva pointed out during the visit that that cork came from Portugal, and Medina added that whoever supplies it to the aerospace industry belongs to the same industrial universe that we associate with the wine and champagne corks. In open sources, that description fits Amorim Cork Solutionspart of the Portuguese group Corticeira Amorim, one of the world’s greatest names in cork. The ESA, in fact, identified Amorim as a supplier of the aerospace variety used in Qarman, although Airbus did not detail there the specific supplier of the parts before us. One of the fascinating things about the space industry is that it always holds some surprises. We can imagine it as a territory dominated by advanced materials, highly controlled processes and pieces designed to the limit, and to a large extent it is. But it … Read more

Spain has 46 million cubic meters of unused biomass. They are a crucial shield against summer fires

by

The summer of 2025 left us a scar of ash and a lesson that we continue refusing to learn. European forests are burning with unprecedented ferocity, but the answer is not to accumulate more firefighters in August, but to return to inhabit and manage the forest in January. The Copernicus satellite balance from the last summer campaign It was, simply, terrifying: more than 403,000 hectares burned in Spain and over a million in all of Europe. However, the truly disturbing information was provided by the European Forest Fire Information System (EFFIS): 217 fires were recorded in Spain, less than half of that in 2022 (493). The burned area, however, was dramatically larger. Fire has not become more frequent; He has become a much more ferocious monster. By the end of 2025, the Copernicus Atmospheric Monitoring Service (CAMS) confirmed the disaster: Europe had recorded its highest fire emissions on record in 2003, releasing almost 13 megatonnes of carbon into the atmosphere. Faced with this scenario, the institutional response remains stuck in the same loop: more seaplanes, more retardation, more summer troops. An emergency strategy that ignores an incontestable reality: the problem does not begin when the spark ignites, but long before, in the silence of the mountains, throughout the year. The diagnosis that no one wants to hear. Every year, Spanish forests add 46 million new cubic meters of plant biomass. Of that amount, according to data from Expobiomassonly around 40% is used. The European average is between 65% and 70%. The rest stays on the ground: branches, bushes, dry leaves, weeds. Year after year. Decade after decade. The result is what foresters have long called “fuel loading.” It is not a literary metaphor, it is pure physics: in the face of a heat wave or a dry storm, this accumulation turns an attempt into an uncontrollable inferno. Galicia, Extremadura and Castilla y León already suffered it firsthand last year. As the Spanish Biomass Association (AVEBIOM) warnsthe origin of this powder magazine is historical. Decades of rural exodus and the abandonment of traditional uses – such as grazing, extensive livestock farming or firewood collection – have left the forests orphaned by the management that, for centuries, kept them safe. Nature didn’t do the dirty work, and we stopped doing it for her. A proposal that reaches the European Parliament. This week, that diagnosis landed in Brussels with its own name. Bioenergy Europe presented in the European Parliament the documentary Fuel the solution, not the fire —in Spanish, “Feed the solution, not the fire”— with a central message: preventing large forest fires involves acting long before the flames arrive. The initiative, supported in Spain by AVEBIOM, shows experiences developed in Greece, Italy and Spain that show how the sustainable use of forest biomass can simultaneously contribute to three objectives: reducing the fuel load on the mountains, generating local renewable energy and boosting rural economies. The proposal is not new in the sector. But that it reaches the European Parliament, at the start of a new high-risk season, gives it a political dimension that it did not have before. The model: from the mountain to the caldera. The idea is, in its structure, simple. When pruning, clearing or forestry treatment is carried out, the remaining plant remains – what was previously abandoned or burned in the forest itself – are collected, crushed and converted into chips or pellets. This material fuels boilers in municipalities, hospitals, sports centers or industries. The mountain is cleaner. The town, hotter. And the energy bill is lower. “Sustainable forest management is part of the response to fires. And bioenergy can help provide an outlet for part of the biomass that needs to be removed from the mountains,” explains Pablo Rodero, head of certifications at AVEBIOM, in statements collected by Energies Renewable. Rodero insists on an important nuance so as not to confuse the discourse: “It is not about ‘cleaning the forest’. It is about managing the territory better, with technical planning and sustainability. When the remains of pruning, clearing or preventive work are transformed into renewable energy, prevention stops being a cost to generate economic activity, employment and energy savings.” The specific actions defended by AVEBIOM range from forestry treatments and the maintenance of firebreaks to the recovery of extensive livestock farming and the promotion of sustainable forestry exploitation. Active management, all year round, that does not depend on the urgency of summer. Real numbers on the ground. Beyond the theory, there is concrete data that illustrates the potential. Veolia Biomass In 2024, it transformed more than 300,000 tons of forest biomass—material accumulated in the mountains—into 700 GWh of clean energy. To get an idea: that is equivalent to the annual electricity consumption of more than 200,000 homes. The company already operates in several Spanish provinces: it works in Moros (Zaragoza) and in the Sierra de la Culebra (Zamora) in the elimination of vegetation on 500 and 400 hectares respectively; carries out thinning and thinning in Mayorga (Valladolid), Barcial, Castropepe and La Hiniesta (Zamora) and Cilloruelo (Salamanca); and has restored 200 hectares in Andalusia affected by the fires of the previous year. He CRECEMOS report on Forest Fire Managementpublished in May 2025, adds another dimension to the equation: sustainably mobilizing one million tons of forest biomass per year would avoid the emission of 580,000 tons of CO₂. In regions such as the northwest of the peninsula, where biomass potential is still underutilized, this approach would combine fire risk reduction with economic reactivation of currently depopulated areas. The European lifeline. It is important to put into perspective what is at stake. Bioenergy is neither an experimental technology nor a niche bet: according to the GROW reportrepresents 60% of all renewable energy produced in the European Union. And 96% of this biomass is produced in European territory itself: it is not imported, it does not depend on foreign regimes, it is not exposed to the vagaries of the global gas market. It is, in other words, the most autonomous … Read more

A scientist wants to build a space shield against solar storms. Your secret weapon: lithium and barium

by

Predict the arrival of very strong solar storms It is important for many reasons. Not only to keep an eye out and not get lost the most beautiful auroras. Also because these could affect satellites or terrestrial communications systems, so it is important to take precautions. The problem is that, no matter how much prevention methods have improved, we cannot do much more than be prepared for what is coming. Today there are no ways to stop these solar storms. However, a scientist from Boston University has announced that it is working on a method to strengthen the Earth’s natural shield against this type of phenomena. A stronger shield. The scientist in question is called Brian Walsh and is working in what he himself has called a wall against solar storms. Its objective is to send six ships to strategic points in a geostationary orbit, so that they release chemical elements capable of strengthening the magnetic field. These should be elements such as lithium or barium, since they are easily converted into positively charged ions when solar ultraviolet radiation hits them. At that point, the cargo released by the ships is converted to plasma. Precisely, what reaches Earth with solar storms is also plasma. However, there is a big difference. The one that comes from the sun consists of charged particles that move at very high speed, with great energy. On the other hand, what would be released into the magnetosphere would be cold, static plasma, which acts as a kind of wall, preventing this high-speed plasma from passing through the magnetosphere. A good shield when the activity is not too intense. The Earth has a great shield against solar storms. Generally, our magnetic field prevents these charged particles from the Sun from crossing into our atmosphere. This is because the magnetic field generally acts as a kind of rail on which the plasma circulates. The electrically charged particles are retained on these rails, but do not cross to the other side. They can only reach the atmosphere at the poles, where the inclination of the magnetic field lines acts as a kind of funnel. Even so, the charged particles that come from the surface of the Sun may already arrive somewhat weakened there. They interact with the gases in the atmosphere, exciting the atoms and causing the release of the light that makes up the auroras. But there are usually not very detrimental effects on communications. On the other hand, if the solar storm is very intense, the particles may be able to deform the rails of the magnetic field, filtering at the poles, but also in other places in the magnetosphere. Historical consequences. The consequences of these types of events have been seen numerous times throughout history. The most dramatic case was possibly that of Carrington eventwhich took place in 1859. It is considered the most powerful solar storm that has been recorded in history with consequences on Earth. Because of this large release of plasma from the Sun, auroras were seen in places as far from the poles as Hawaii and Cuba, but there were also less noticeable consequences, such as the burning of telegraph lines in many parts of the world. Another very notorious and dangerous case took place during the Vietnam War, in 1972, when a solar storm caused the accidental detonation of several magnetic underwater mines. And much more recent is the Gannon Storm, which in 2024 affected the GPS systems of planting tractors in several locations in the United Statescausing losses of 500 million dollars among farmers. But the situation could be worse. It is estimated that a major storm like Carrington’s could occur once a century. There hasn’t been one this big since then, so it could happen in the not too distant future. And today we depend much more on technologies than then. It is estimated that the losses could be more than 2 billion dollars. A natural process. This artificial wall that Walsh wants to create is inspired by a process that occurs naturally. And the thing is that, from time to time, small fragments of the Earth’s atmosphere break off and join the magnetic field, reinforcing it before the arrival of charged particles from the Sun. Lithium and barium would do something similar, artificially. Simulations only: For now, Brian Walsh has only made simulations of his invention, he has not tested it in space by any means. He himself recognizes that it is a complex process, so it must be done perfectly so that it causes more benefits than problems. Releasing ionizable elements at random could be harmful if not done in the right place. In addition, ways must be found to put ships in the correct place in their orbit before the storm arrives, so it is important to speed up the process while improving prediction methods. Handicaps. Although it may seem like a lot of mass is required to carry out this procedure, Walsh insists that the payload needs fall within current launch capabilities. However, he recognizes that it is an expensive process. Therefore, it would be necessary to look for ways to optimize it so that the necessary investment is not so large. For example, you want to work on pulsed release so that ionizable material is not wasted. In short, this method of controlling space weather is not at all something that will be used imminently, but it is clear that in the future we will need something like this. If not this method, another, but we greatly need something that protects us from the harshest elements of the Sun. Image | NASA | Walsh et al.

Alzheimer’s leaves its mark decades before showing its face:; keeping vitamin D at bay is already a promising shield

by

Alzheimer’s and other forms of dementia remain one of the most complex medical puzzles of our era, standing out above all for the absence of treatments that completely stop the disease or even reverse it. But science continues to advance and has now focused on a preventive factor that could be in our hands from a young age: vitamin D. It keeps moving forward. The main study that has sparked interest was published at the beginning of this month of April in the magazine Neurology. And the objective of this was none other than to shed light on how our brain behaves decades before the classic symptoms of dementia appear. To get here, a total of 793 participants from the renowned Framingham Heart Study with an average age of 39 years were monitored. From here, the serum vitamin D of the patients began to be measured between 2002 and 2005, and then, at the age of 16, they underwent different scans to check the state of the brain. What was seen. In conclusion, the study pointed out that maintaining higher levels of vitamin D, greater than 30 nanograms per mL, during the ages of 30 to 40 is associated with less subsequent accumulation of the tau protein in the brain. Because it matters. The relevance of this discovery is crucial and to understand it, you just have to know that Alzheimer’s occurs because two factors mainly come together: Beta-amyloid protein plaques, which accumulate outside neurons. Neurofibrillary tangles of tau protein, which form within the brain cells themselves and are closely linked to neuronal death and cognitive decline. In this way, the effort of science right now is focused above all on blocking the formation of beta-amyloid plaques around neurons or preventing the tau protein from accumulating in our neurons. Although it is something really complicated. There is a nuance. Interestingly, the study found no association between midlife vitamin D levels and beta-amyloid accumulation. The protective effect is limited exclusively to the tau protein, especially in the brain regions where Alzheimer’s usually strikes its first blows. This is good news, as it narrows down the biological mechanisms involved and suggests that vitamin D could play a specific role in the pathways that regulate how tau is produced or eliminated over the years. There is small print. As they warn in the press release itself, this is a simple observational study. This means that it is true that people with higher vitamin D in middle age accumulated less tau protein, but the study cannot categorically state that vitamin D destroys tau protein on its own. Furthermore, the authors of the study themselves are categorical: this finding is not a medical prescription. There is no current evidence to justify that massively supplementing with vitamin D pills at age 40 will protect the brain against dementia. This simply paves the way for future research to truly test this relationship in a clinical trial and lead to new treatments.

This is the nitrogen plant that will shield electric mobility

by

Extremadura is ceasing to be solely a heritage and agricultural reference to consolidating itself as a new strategic pole on the map of the international energy industry. The latest confirmation of this metamorphosis comes from China: the multinational Jinhong Gas. This Chinese giant has chosen the regional capital to take the leap and install its first factory in all of Europe. In short. As stated in a resolution of the Official Gazette of Extremadura (DOE)the Government of Extremadura has been released to public information the request for Unified Environmental Authorization (AAU) for this project. With this movement, a legal period of 20 business days is opened so that any person or entity can consult the technical file and present the pertinent allegations before its final approval. More in depth. In fact, to protect this operation, the Asian corporation has already formally established in the city the commercial company ‘Jinhong Gas (Spain) SL’, injecting an initial share capital of 100,000 euros. In economic and logistical terms, the main objective of this nitrogen plant is to directly supply the future gigafactory of materials for cathodes for electric vehicle batteries promoted by its compatriot, the Chinese company Hunan Yuneng, and which plans to mobilize 800 million euros and create around 500 direct jobs. The basis of the project. The DOE provides a technical x-ray exhaustive. The factory will be built on plot I-18 of the Expacio Mérida business park, occupying an area of ​​12,000 square meters. Its forecasts are massive: operating about 8,000 hours per year, the facility will have the capacity to produce up to 100 million cubic meters of nitrogen per year (17,000 Nm3/h). The industrial process, according to the official documentwill use cryogenic air separation technology. This means subjecting the air to a complex circuit that includes compression using 1,250 kW turbines, purifying drying to eliminate CO2 and humidity, and extreme cooling using pumps that operate at -196 ºC. All this happens in a “Cold Box” where the air is distilled to obtain nitrogen with a purity greater than 99%. At a logistical level, the production will be sent in gaseous format through direct pipelines to the final consumer (like neighbor Hunan Yuneng). The rest will be stored in a liquid state in two monumental vertical cryogenic tanks, 4 meters in diameter and 250 cubic meters in capacity each, for sale to third parties. To maintain this production rate, the project estimates an annual consumption of 36.8 GW of electrical energy and 96,000 cubic meters of water. The thirst for megawatts. Like the Extremaduran gigafactories, the technological giants that land in the country share the same need: an inexhaustible thirst for stable and cheap energy. And this is where Spain has the resources to lead the continent. Thanks to an unprecedented photovoltaic and wind deployment, the country has earned the right to dream of being the great “Europe battery”. This immense renewable potential is the perfect magnet for the new electro-intensive industry and is what drives us in the race to be the great hub of data centers in southern Europe. To pave the way, the Government is already making moves to shield these macroprojects from electrical costseliminating anachronistic barriers such as the obligation to consume at night (the old off-peak hours), a requirement that does not make sense when our solar energy overflows the meters at noon. Kilometer zero of the new industry. With earthworks already started in ExpacioMérida and environmental procedures in their public exhibition phase, Extremadura takes an irreversible step. The ancient Roman capital embraces the 21st century, assuming a leading role. It is no longer just about attracting Asian multinationals, but about demonstrating that Spain can combine reindustrialization with clean energy, establishing itself as the perfect ecosystem for the mobility and technology of the future.

Ukraine and the secret of its energy shield

by

In 1973, a political decision was enough to unleash a global energy crisis. Today, that same effect can be caused by a swarm of drones or a few naval mines. Meanwhile, the infrastructures that support the world’s supply remain, in many cases, enormous facilities designed for another era, when the greatest danger came from the sky in the form of missiles, not small, cheap and constant threats. The five-day countdown. Five days leftactually slightly less than four troops, so that a specific threat can change the global energy balance, and it all starts with a tactical move: the United States has gone from a 48-hour ultimatum to bomb Iranian power plants to a five day break supported by diplomatic contacts that are still very weak. We are talking about a maneuver that does not imply real de-escalation but time gained to avoid a step that could trigger immediate retaliation throughout the region and, above all, convert the energy infrastructure in priority objective of open war. The real fear. The key to these hours is not only in the military fronts, but in the possibility that the conflict begins to knock down energy nodes systematically. The United States has come to put the attack on the table to electrical installations Iranians. For its part, Iran has responded by threatening to mine the gulf routes Persian and turn the area into an almost blocked space. Between one thing and the other, the message is more or less clear, because the war no longer revolves only around bases, scientists or arsenals, but around cables, terminals, pumping stations, along with oil ports and maritime corridors without which the entire planet begins to tremble. Kharg, Hormuz and the heart of the industry. The Kharg island appears in this story like a lot more than a point on the map. It is the great exit center for Iranian crude oil. It is also one of the places where a military offensive would a direct effect on global oil flows. Plus: it adds to the other decisive name of this war, the Strait of Hormuzthrough which a gigantic part of the world’s crude oil trade passes. When both places enter the equation at the same time, what is at stake stops being a one-off retaliation and becomes the real possibility of a prolonged shock to the global energy industry. Ukraine, again. That’s why everyone is looking at Ukraine again. I remembered this morning the new york times that the planet does not do it only because its war turned drones into absolute protagonists of the battlefield. It does so also because it was one of the first places where it was understood that modern energy infrastructure could survive only if it was transformed into a stepped fortress. Because Russia was hitting refineries, gas plants and critical nodes for years. And Ukraine responded building a shield made of electronic warfare, interceptor drones, physical defenses, dispersion of equipment and hardening works that sought one very simple thing: to continue functioning even under constant attack. The secret: hold on. From that perspective, the main Ukrainian lesson is not to have found a perfect defense, because that may not exist. Rather, it consists of having assumed that the enemy will hit again again, and in reducing damage, protecting the most expensive components, bury part of the facilitieserect concrete barriers and add layers of jamming and interception to complicate each attack. In short, it consists of moving from the old logic of protecting large infrastructures as if they only had to resist a major bombing from the last century, to a new logic in which you have to resist repeated waves of small, cheap and constant threats. The Gulf discovers the Ukrainian problem. Because the Gulf countries had thought above all about missiles. Ukraine it took time adding to the equation the drone swarms cheap. This difference is decisive because taking down low-cost threats with very expensive systems is not sustainable for a long time. And that is where the Ukrainian experience becomes valuable for the Middle East: not because of a miraculous technology, but because it has developed a layered defense. more flexible and cheaperadapted to an enemy that can saturate the sky with relatively simple but devastating devices for gigantic and very vulnerable installations. Few days to understand where the war is going. If you like, the central idea of ​​these hours is brutally simple. There are few left less than four days to check if the pause announced by the United States It serves to cool down the war or only to bring it closer to its most dangerous phase. If it fails, the focus will no longer be just on who bombs who, but on whether the region’s energy industry can continue standing. And in that scenario, Ukraine reappears as an unexpected reference one more time. First It was the laboratory of drone warfare, and now aims to also become the emergency manual to protect power plants, plants and terminals in an era in which energy has become one of the most delicate and decisive targets on the board.

Mexico wants to shield the ancient Mayan city of Toniná at all costs. So he has expropriated more than nine hectares

by

Maybe not as well known as Teotihuacan, Chichen Itza or even the neighbor Palenquebut Toniná It is one of the great archaeological treasures of Mexico. The necropolis experienced its heyday between 600 and 900 AD and today it is preserved as one of the most fascinating complexes of the Mayan area and pre-Hispanic urbanism. In fact, it is crowned by a unique pyramidal structure in the region that is taller than the famous pyramid of the sun of Teotihuacan. Therefore, to guarantee its conservation, the Mexican Government has just made a radical decision: expropriate 9.2 hectares of the environment so that they become directly dependent on the National Institute of Anthropology (INAH). What has happened? That Mexico has just shown that it is willing to pull expropriation decree to protect your assets. And he has also done it in a practical way. The Executive led by Claudia Sheinbaum has announced that the National Institute of Anthropology and History has “taken possession” of a 9.22-h property in the vicinity of the Toniná site, in the state of Chiapas. The curious thing is how that land has been obtained, until recently in private hands. The transfer has been possible thanks to a decree that gave the green light to the sale in favor of the INAH. “The action arises from a cause of public utility, promoted in December 2025 by Culture,” clarify the authorities. Why have they done it? The Executive’s objective is twofold: to facilitate the conservation and research of the environment. In the words of INAH itself, the idea is to “guarantee the optimal conditions” of the site. “Toniná is an essential part of the living history of Chiapas and Mexico. This decree protects an asset of the nation and contributes to the exercise of cultural rights through access to knowledge and historical memory,” reasons Claudia Curiel de Icaza, Secretary of Culture. The leader insists that with the measure the State reinforces its capacity to “preserve heritage, ensure its management with technical criteria and sustain conservation, restoration and research tasks.” From now on, the INAH will expand its capacity to monitor, care for and study the ancient Mayan city. Why is it important? For several reasons. Beyond the legal formula used or its advantages to protect, conserve and study the site, the measure is interesting because Mexico wants to take advantage of it to promote Toniná. “In the archaeological zone, a comprehensive reactivation program will be implemented that will create a structured route for its eventual reopening,” keep it up the INAH. In fact, one of the objectives is to promote “responsible tourism.” Click on the image to go to the tweet. Is Toniná so important? Yes. And that is another reason why the recovery of the nine hectares has generated so much expectation. Located on the border between the Mayan highlands and the lowlands, the inhabitants of ancient Toniná left a fascinating acropolis, with overlapping platforms and a pyramidal structure that archaeologists considered “unique” in the Mayan world. In fact, it surpasses in height the famous Pyramid of the Sun of Teotihuacán, 65 meters. “The richness of this archaeological zone makes it comparable to other large sites in Chiapas, such as Palenque. Its heyday goes from the year 600 to 900, within the Classic period, and it was the last witness to the decline of the so-called Old Mayan Empire,” explains the INAH. The most famous governor in its history was Tzots Choj (‘Tiger-Bat’) and its greatest archaeological treasure is offered by its acropolis and central plaza. In it we find a staircase of 260 steps, the enormous pyramidal structure and a labyrinth of temples, palaces and roads. Experts have also located an altar for sacrifices and spaces to play ball. How long have we known her? The first to tell us about Toniná was Brother Jacinto Garridoin the 17th century, but the site has continued to fascinate experts since then. During the 19th century, expeditions continued and throughout the 20th century (especially between the 1970s and 1980s) excavations intensified. It was then when the studies and conservation work carried out by the INAH were launched, which has allowed its secrets to be discovered. Despite years of study, the archaeological institute trust in which there are still surprises: “Toniná still keeps many secrets that will have to be known.” Images | Wikipedia and SC (INAH) In Xataka | The Mayan Train has become a nightmare for Mexico: what seemed like a great plan has run into justice

In 2022, the gas crisis skyrocketed the price of electricity in Spain. In 2026 we have a “green shield” but also a serious problem

by

Just when in Spain we began to breathe a sigh of relief, convinced that we had overcome the inflationary trauma of 2022 “after cutting energy ties” with Russia, history repeats itself. This week a “black Monday” began that has shaken international markets. This time the epicenter is not in eastern Europe, but in the Persian Gulf, after the recent attacks that have been forced to paralyze QatarEnergy facilities. The impact on our country has been devastating. According to data collected in OMIEthe price of electricity in the wholesale market has jumped 60% in just 24 hours, climbing to 90.14 euros per megawatt hour (MWh). To put it in perspective, this represents a 1,300% increase in price compared to what we paid just a month ago. The President of the Government, Pedro Sánchez, has already warned that We must prepare for a “long war” with serious global economic consequences. And the fear is already palpable in the street with the long lines that yesterday we observed of drivers trying to fill their tank at gas stations low cost before prices continue to rise. If the gas goes up, why does the electricity go up? To understand why a conflict thousands of kilometers away makes our electricity more expensive almost instantly, you have to look at how our system works. As explained The Confidential in a very didactic way: the European electricity market is “marginalist”. This means that the most expensive technology that needs to be used to cover the demand of a specific day is the one that sets the final price of all energy. If the sun or wind is not enough and the gas plants have to be turned on, all electricity is paid for at the price of gas. And the gas, right now, is trapped in a war funnel. As we have already explained these days20% of the liquefied natural gas (LNG) and 25% of the world’s oil transit through the Strait of Hormuz (the epicenter of the current tension). Any threat of a blockade in that area generates a domino effect that triggers reference prices in Europe. The energy expert Joaquín Coronado explained in LinkedIn that this panic is already real: The prices of electricity futures for the rest of 2026 have suddenly risen by 24%. As he himself points out, “only the price of gas has changed,” but that is enough to drag down the entire system. The hit in the pocket. All this macroeconomics lands directly in the bank account of citizens. As pointed out The Countrythere are more than 11 million users in Spain who have regulated rates (the PVPC for electricity and the TUR for gas) who will notice this increase almost immediately, since their contracts reflect the daily fluctuations of the market. The calculations about what this crisis is going to cost us are already on the table: The OCU, in statements to The Newspaperestimates that if these prices are maintained, the average electricity bill with a regulated rate will jump from the 62 euros we paid in February to around 82 euros in March. An increase of 30% in a single month. A platform report Roams figures the monthly impact about 12 euros extra for electricity (17% more) and increases of up to 18% on the gas bill. The worst scenario is drawn the comparator Selectra: If the conflict drags on and we return to the panic levels of 2022, the electricity bill could skyrocket by 200%. But energy is just the first domino. Financial Times collect warnings from the chief economist of the European Central Bank (ECB), who already assumes a short-term rebound in general inflation. As oil rises, transportation rises: from fuel at the pump (gas stations already assume extra costs of 12 cents per liter) to maritime freight of goods and plane tickets, which on some routes to Asia have quadrupled in price. So, are we the same as in 2022? The good news is that we are not exactly at the same starting point as when the Ukrainian war broke out. As analyzed elDiario.esSpain today has three “mattresses” that cushion the first impact: the arrival of spring (which reduces the use of heating), some reservoirs 83% full (which allow generate a lot of hydroelectric energy cheap) and an electric mix where more than 50% of energy is already renewable. Furthermore, the PVPC formula was recently renovated so that it does not depend only on the daily market, softening the extreme peaks a little. The bad news is that we have exchanged one problem for another. To stop depending on Russia, we throw ourselves into the arms of the United States. As the economist José Carlos Díez warns in the chain Vibe Zero44% of the gas we consume today comes from the US. This places us in a position of extreme vulnerability to the new geopolitical “black swan”: the anger of Donald Trump. The refusal of the Spanish Government to give up the military bases of Rota and Morón for the offensive against Iran has caused Trump to threaten to cut off all trade with Spain. If the United States turns off the tap on LNG ships, José Carlos Díez warnsSpain does not have the physical capacity or infrastructure to replace a supplier that gives us almost half of our gas from one day to the next. The social shield and our pending duties. Faced with the threat of the crisis becoming entrenched, the Government is already moving. According to Expansion, If the conflict lasts more than four weeks, Pedro Sánchez’s Executive has on the table reactivating the “social shield” of previous crises: reductions in VAT on electricity, fuel discounts and direct aid. However, fiscal patches do not hide the underlying problems. In Xataka We have put our finger on two great absurdities of our system. On the one hand, we are an “energy island” since we have seven regasification plants capable of receiving ships from all over the world and helping Europe, but we do … Read more
