The emptied rural Spain has been revealed as the great energy engine of the State

by

Spain is a State full of contrasts. At a demographic level, the population density is concentrated in Madrid and coastal cities, that is, 30% of the territory concentrates 90% of the people. It is “tight Spain.” The rest, approximately five million people, occupy 70% of the territory, in the interior of the peninsula. More people consume more resources, which puts two realities on the table: Madrid consumes more and generates less energy than anyone else and that emptied Spain is the energy engine of the State, as the report summarizes “The energy transition in the Spanish rural environment” prepared by Monitor Deloitte. The most striking fact: 84% of renewable energy generation comes from rural environments. Context. In the collective imagination we associate energy production with large nuclear or fossil fuel installations, but nothing is further from current reality. Spain is carrying out an energy transition collected in the National Integrated Energy and Climate Plan with the objective of reaching 81% electricity generation from renewables. And it’s on the right track: the report of the Spanish Electrical System of Red Eléctrica for 2023 It showed that it had already exceeded the 50% quota. At specific moments, has reached 100% supply. Listing renewable sources by their importance, we find wind energy prominently, followed by photovoltaic and hydraulic energy. Where. In rural territory, in that sparsely populated place where natural resources and space abound. The report highlights regions such as Castilla-La Mancha, Castilla y León and Aragón as hubs precisely because of their availability of soil and climatic resources (radiation and wind). Why is it important. Because the State needs that emptied Spain and its resources to successfully carry out its energy transition. Without that territory or its available resources, there is no decarbonization or energy sovereignty. Obviously a paradox occurs: that the most populated places are those that produce the least energy and vice versa, which generates a territorial imbalance. However, this deployment of infrastructure can become an opportunity to promote local employment and thus establish the population. Finally, agrivoltaics is revealed as a way to modernize the agricultural sector, making it possible to make cultivation for food compatible with energy supply, all on the same soil. In figures. In addition to this substantial share of 84% of renewable energy from rural areas, the report reveals other interesting figures: There are 15 provinces with critical population density (

68% have serious damage

by

More than half of the Spanish road network accumulates serious or very serious damage. This is how it specifies the latest report of the Spanish Road Association (AEC). And according to the study, the deterioration has skyrocketed in recent years and the bill to fix it now exceeds 13,000 million euros. Among all the Autonomous Communities, Aragón occupies the last place in the ranking of the roads with the worst condition. A problem that does not stop. In July 2025, the AEC published its audit on the state of the national road network, and according to the association, the roads are in the worst state “since the late 1980s.” In 2022, the AEC estimated in its audit that there were about 13,000 kilometers of roads that had very serious pavement damage. Today that figure is close to 34,000almost triple in just three years. What exactly does “serious impairment” mean? He report The AEC distinguishes two levels of urgency. On the one hand, there are 34,000 kilometers that need immediate reconstruction (in less than a year) because they present serious structural damage: deep potholes, what is technically called “crocodile skin”, longitudinal and transverse cracks, and peelings in the asphalt. On the other hand, another 20,000 additional kilometers require intervention within four years. In total, more than 54,000 kilometers, out of a total network of 101,700, are in a more or less compromised situation. The invoice. The accumulated road maintenance deficit amounts to 13,491 million euros, according to the AEC, which updated the figure in 2025 taking into account inflation and the increase in the cost of materials and labor. Compared to 2022, the cost necessary to fine-tune the infrastructure grew by 42.7%. Of that amount, 4,721 million correspond to the State network and 8,770 million to roads managed by autonomous communities and provincial councils. Aragon tops the ranking. According to the association, 68% of its road network presents serious deterioration, sixteen points above the national average. As the AEC says, it is the only community that is at a “critical” level, which implies that most of its roads are not only bad, but require practically immediate action. The deficit per kilometer in Aragon reaches 150,632 euros, also the highest in the country. The motor expert Alfonso García ‘Motorman’, analyzed the figures in the COPE program Putting the Streets, counting that “riding on our roads and highways has become a risky activity.” The state in other Communities. Just behind Aragón, with 59% of its network in serious condition, are Castilla-La Mancha and Galicia. They are followed by Asturias, La Rioja, Castilla y León and the Region of Murcia, all above the 52% national average. At the opposite extreme, the communities with the lowest percentage of deteriorated roads are the Valencian Community (32%), the Madrid Community (38%) and Extremadura (40%). Driving on bad asphalt is expensive. According to AEC calculations, driving on a road in poor condition can increase fuel consumption by up to 12%. Only during July and August of last year, the association estimated that the overspending on gasoline and diesel derived from the poor condition of the roads would exceed 270 million euros, considering the more than 100 million journeys long-haul that the DGT provided. According to the report, the deterioration of the pavement also forces the average speed to be reduced by 10%, which makes the transportation of goods more expensive and, as a consequence, pushes up product prices. AI enters the scene. Until recently, the AEC audited roads with a classic visual inspection methodology, that is, with evaluators traveling sections on foot or by vehicle. In 2023 the transition to a digital inspection system based on artificial intelligence. A vehicle equipped with sensors travels along the road at up to 90 km/h and collects images that are later processed using artificial vision in the cloud. The result is a sample of 4,000 kilometers compared to the 300 that were previously analyzed with visual methodology. What solutions are proposed. The AEC has been calling for years for a specific and stable financing fund for road maintenance, which would combine public budgets, European funds, pay-per-use systems and public-private collaboration. Also point to a possible financing route that has no extra cost for drivers: making the special hydrocarbon tax also paid by rail, maritime and air transport. Thus, they say, some 4,091 million euros would be generated annually, enough to liquidate the accumulated deficit in just over three years. A few weeks ago, the Minister of Transport, Óscar Puente, announced an injection of 1,629 million euros to face the situation, although at the moment it is far from being enough.

Google is going to build a mega data center in a state where the drought is atrocious. Your cooling plan: use air

by

The American state of Texas has been dealing with heat wavesdroughts and a increasing pressure on its aquiferswhich makes it on paper one of the worst places to set up a data center. Well, Wilbarger County in Texas is just the place chosen by Google to set up your next data center. But big tech hides an ace up its sleeve: it is not going to use water for cooling, but air. Context. Briefly, a data center is an industrial facility full of servers where information transmitted over the internet, such as AI responses or your Google photos, is stored and processed. And if your personal computer requires cooling when it has been working with a certain intensity for some time to dissipate heat, more of the same with servers, which operate 24/7. The usual thing in these plants is to use thermal dissipation systems with water, either with chillers, evaporation or direct cooling with immersion, thermally efficient solutions, but problematic if water is scarce. The problem? That Texas is an oven that is not for buns: its drought is pressing. But Texas is not a foreign place for Google: it has been in that state for more than 15 years, where it has operational centers in Midlothian and Red Oak and already plans to build two more campuses in Armstrong and Haskell Counties. It’s very serious. The project. The Wilbarger County data center will reduce water use so much that it will restrict its application to basic campus uses such as kitchens and services. As? Google has not provided details of the technology, only that it will be advanced air cooling. Cooling with air in such a hot scenario implies greater energy consumption, so the problem now becomes electricity. What Google proposes is a “Power first” model. In short: the data center goes hand in hand with its own renewable electricity generation plant. Google’s energy partner for this project is AESone of the largest producers of renewables in the US, with whom it has a 20-year energy purchase agreement at an agreed price. This is how both win: AES has stability to build the plants and Google has the guaranteed supply and price. Furthermore, according to Google, they already have the land and the interconnection signed, which saves bureaucracy and launches the project into the construction phase. Why is it important. Because according to EESI estimatesa medium-sized data center can consume 416 million liters per year for thermal dissipation alone, the equivalent of a thousand homes. And if there is a shortage of water, allocating it to meet the needs of a data center is hardly justifiable. Wilbarger’s project solves this with air cooling, removing the precious commodity of water from the equation, but also from the electrical grid itself: Google cooks it and Google eats it (with the help of AES). Given that the demand for computing continues to grow, a model that does not consume water or overload the network emerges as a solution to a resource management problem. In figures. For Google, Wilbarger County is not a pilot plant and its size demonstrates this: 0 liters of water for cooling. The project will provide 7,800 MW of power to the Texas grid. The agreement between the technology and energy companies is for 20 years. Google advertisement an investment item of 40 billion dollars for Texas in November 2025 and has provided a $30 million fund to boost energy initiatives in Texas from 2026 to 2028. It won’t be easy. Although Google has been cryptic when it comes to reporting what the technology, its capacity and needs will be, the reality is that when cooling with air in a hot climate, the pressure is transferred to the electrical grid. On the other hand, and although this specific project points the direction of a possible solution to this problem, we will have to see if and how it can be scaled, because there are more and more data centers and the climate is increasingly more extreme.

With so many models of Bluetooth locators, you may feel lost, but we are going to try to simplify things a little to help you choose one or the other. Next, we are going to analyze which is the locator that best suits you according to the mobile phone you have and your needs and budget. One of the essential things when it comes to understanding these devices is that They use the network of nearby users to locate each other. The AirTag works because there are millions of iPhones passing nearby and the same goes for those compatible with Android’s Find My network. In Spain, it must be taken into account that there are more Android mobile users than iPhones, while Tile (which we will also analyze later) only works if users have the Tile app installed, so if you live in a lost town, it will not be of any use to you. Of course, all of them have in common that they feed themselves through a standard button cellwhich will cost you two euros to change it a year and you will forget to charge the device. In addition, they are IP67 certified, which means they will survive without problems if you drop your keys into a puddle or the toilet, for example. Apple AirTag, the king of precision and the perfect one for iPhone users He Apple AirTag2 It is the absolute reference for iPhone users. The pursuit of precision is taken to another level thanks to the new U2 chip, allowing you find objects almost 60 meters away with an arrow that guides you step by step. In addition, its integration with the Apple Watch and the accessories ecosystem (such as cases and keychains) is unattainable for the rest. The best thing about its chip is that it is very powerful and precise, allowing your phone to tell you that the object is “two meters to your right” with a centimeter precisionsomething that normal Bluetooth does not do. In addition, it is considered one of the best since there are many iPhones in the world (and also in Spain), which makes locating objects much easier. Faced with this precision, the AirTag has a but and that is that it sells you an incomplete product.

Generation Z has found the remedy to streaming subscription fatigue: buying DVDs again

by

Sales of DVD, Blu-ray and 4K UHD stopped their decline in 2025. They only fell 9% compared to declines of more than 20% in the previous two years. What is the reason for this slowdown? To an unexpected factor, an unforeseen audience: young people from Generation Z who are filling video stores, promoting labels boutique like Criterion and Arrow and turning the physical format into a gesture of resistance against the massification of streaming. Plummet. For more than a decade, the physical format market in home video followed a downward trajectory that seemed irreversible. Between 2019 and 2023 it was reduced by 40% in the United States alone, and the disappearance of chains such as blockbuster it reinforced the feeling that the album was an exhausted medium. In 2024, DVD and Blu-ray sales were below a billion dollars for the first time. Gasping. However, in 2025 a different phenomenon has been detected: the physical disk market generated 870 million dollarsthat is, it only decreased by 9.3% compared to the previous year. What’s more: in the 4K UHD segment (which allows high-quality viewing at home), US consumer spending grew 12% year-on-year. All this in an extremely unfavorable context: with the unstoppable growth of streaming (19.8% in 2025), the physical format represents only 1.4% of total home entertainment. Fed up with streaming. The overdose of supply in streaming is ultimately causing a tiredness effect. According to recent studies47% of American consumers say they pay too much for their insurance services streamingand 41% consider that the available content does not justify the price. The average number of subscriptions per household has been four for a couple of years, an amount that could be at its critical point. DVD solution. Added to this saturation is a problem that film fans know well: the platforms are unreliable and the catalogs change without prior notice. Movies and series disappear for reasons ranging from the completion of exploitation contracts to tax reasons. In a ‘Los Angeles Times’ piece that has investigated this interest Of the youngest to recover physical formats, some young people under thirty spoke about how they became interested in cinema during the pandemic, describing DVD collecting as an act of rebellion against the fragmentation of streaming. Blockbuster, meeting point. That same article talks about renovated versions of old video stores as meeting points for these new collectors. Of course, it is something that mainly concerns the United States, where such specific types of businesses make sense: Vidiots, in Los Angeles, also functions as a movie theater, and is registering its highest revenue peaks since its opening, with an average of 170 daily rentals. Also from there is Cinefile, which has 500 paying members. Visiting the video store functions as a social activity that streaming cannot offer and the community dimension is key to understanding why the phenomenon exceeds pure nostalgia. And you don’t have to go to such specialized stores: Barnes & Noble, one of the few large chains in the country that maintains a space dedicated to the physical format after the withdrawal of Best Buy and Target, speaks of a double-digit percentage growth during the last year. And they point out that the demographic profile of their buyers is increasingly younger. Stamps boutique. The situation experienced by domestic editions is completely unprecedented in the history of the medium: while the major studios reduce their commitment to the physical format, independent labels are experiencing a moment of expansion. Criterion Collection speaks of “significant year-over-year increases” in sales. The cult film specialist Vinegar Syndrome also experiments similar trends. Of course, sales are incomparably lower than the good times of the physical format, but we are not talking about residual phenomena either. In Spain alone, for example, there are half a dozen labels specialized in reissues of films that cannot be found in streaming (El 79, Cameo, Gabita Barbieri, Trashorama…) that survive crises and recessions alluding to a loyal audience and a cinema that cannot be seen any other way. The inevitable comparison. It is inevitable to think of an analogy with the vinyl recoverythe cassette and the VHS that the previous generations, Millennials and Gen-Xers, have carried out. This has been going on since the mid-2010s, in a mix of nostalgia, vindication of the physical and endless discussions about audio and video qualities. Two decades latervinyl is facing its eighteenth consecutive year of growth, with $1.4 billion in sales (the highest figure since 1984) and 44 million units in stores, surpassing the CD for the third consecutive year. The key difference is that vinyl has an industrial infrastructure that supports it: record companies that prioritize the format, active manufacturers and a distribution chain. The physical video, on the other hand, loses player manufacturers and the big studios prioritize streaming about the disc editions. Video game consoles, eternal support of the format, already have institutionalized versions of their hardware without disc readers. At the moment, the recovery of DVD and Blu-Ray is an isolated phenomenon. But those who we keep listening to cassettes We know better than to look over our shoulders at a format that seems dead.

The mayor of Lisbon has turned it into a magnet for European startups

by

Carlos Moedas does not feel like a conventional politician. The current mayor of Lisbon and former European Commissioner for Innovation recently insisted in which his training as an engineer marked his management. The idea: less rhetoric and more structural solutions. And it certainly seems to carry out this proposal, because it is leading a transformation that seeks to position the Portuguese capital not only as a tourist destination, but as one of the most relevant technological nodes in Europe. unicorn factory. The nerve center of this transformation is the call Unicorn Factorya hub of innovation that was launched in 2022 and that has become the flagship project of its mandate. Since its creation, this initiative has multiplied its size by five, and today it already houses thematic divisions specialized in cutting-edge sectors such as AI, blockchainhealth or green technologies dedicated to the agricultural field. The success is tangible: 17 “unicorn” companies (valued at more than $1 billion) have moved their operations to the Portuguese capital. Attracting startups. Moedas explained in comments to Financial Times how the real challenge of Lisbon is not to see companies born, but to help them grow. The project attracted 300 companies in 2025, a figure that represents notable growth from 250 the previous year. Among them there are companies with founders from the US, Brazil, or Denmark. Favorable conditions. To attract these startups Moedas has used several levers. The first is to sell Lisbon for what it is: a safe capital with a great quality of life. The second is to highlight that the tax regime for qualified immigrants is advantageous, and there are also tax credits for R&D, which of course is a strong argument for companies that consume a lot of resources in those initial phases and can thus receive aid in this process. But. The road, Moedas openly acknowledges, is not without potholes. Portuguese bureaucracy remains complex – the same thing happens in Spain – and that can deter entrepreneurs. The mayor of Lisbon states in the interview that a good part of his time is spent talking on the phone with foreign founders and helping them overcome these bureaucratic barriers. “Politicians do not create jobs, the markets create them,” he repeats: their job is to facilitate, not hinder, or at least that is the message. Competence. Although the activity is notable, there are founders of companies who know that the market is raffling them off. María Ribeiro Soares, from Immersiv Studios, warned of the difficulty retaining talent compared to markets with higher wages such as the United Kingdom or Germany. The other venture capital. There is another peculiarity in this entrepreneurship market. Lisbon startup founders have realized that while traditional venture capital is cautious, the so-called family offices are very willing to bet on these projects. These investors, often experienced, high-net-worth former founders, provide funding but also advice. Lisbon is not alone. The rise of Lisbon as a technological node is also accompanied by other Portuguese innovation centers such as Braga and Porto, where, for example, the biotechnology sector flourishes. There is also a direct connection with universities oriented to this market, and in that northern region of Portugal alone there are already some 1,200 startups with a combined valuation of close to 9 billion euros, according to the FT. The other great challenge. Portugal’s efforts to attract external talent have led to the arrival of numerous digital nomads, but this has had a counterproductive effect: it is causing an exodus among young Portuguese. They cannot access a housing market adapted to the pockets of those nomads, who charge triple. Rental prices have skyrocketed, and that has created tension that the mayor must manage.

We have been adoring bananas all our lives for their potassium. Science points to raisins as the true “super snack”

by

In recent years it is easy to see on social networks like TikTok or Instagram different ‘specialists’ in sports or nutrition bombarding with different food supplementswith the best ‘super foods’ for good nutrition and more. However, in a corner of the pantries we may have a food that we despise, but that can give us many benefits in our daily diet: raisins. A great ally. A product that may be hated by many people because of its texture, but has been introduced by different nutrition experts as a very interesting option. The reason lies in the dehydration process, since raisins surpass very popular fresh fruits such as strawberries or bananas in nutritional density. The why. When we remove the water from a grape, what is left is a bomb of bioactive nutrients. This is what verified databases like the USDA and FatSecret point to, since a standard serving of 40 grams of raisins provides about 120-129 calories, between 1 and 2 grams of fiber and around 300 mg of potassium. And this is where the odious comparison comes in with the historical king of potassium and the one almost baptized as the treatment for soreness after sports: the banana. On paper, a medium banana has around 350-425 mg of potassium, while raisins, being dehydrated, They can reach 860 mg of potassium per 100 grams. In this way, we are talking about a brutal concentration of minerals that are key for the nervous and muscular system. What does science say? Far from being a simple grandmother’s remedy, the impact of raisins on our health is widely documented in different articles. One of these is an analysis published in 2017 which brought together almost 22,500 adults and revealed large numbers. Specifically, regular raisin consumers had 34% more fiber in their diet, 16% more potassium and on top of that they consumed 17% less added sugars. The results here were a 39% reduction in the rate of obesity and a 54% lower risk of metabolic syndrome. Effect on pressure. Beyond being a food that can be very attractive to gym lovers with the aim of alleviating soreness and also reducing sugar consumption, it can be ideal for our blood pressure. Here science has been able to see that the phenols and polyphenols of raisins have a powerful antioxidant effect, and that is why in patients with diabetes and hypertension, consume three servings a day manages to reduce blood pressure between 5 and 8 mmHg. But it doesn’t stop there, since it can also lower glucose levels after eating something and reduce very important inflammatory markers. At the digestive level, a 14-day trial showed that the fiber in this food acts as a powerful prebiotic, promoting the growth of butyrate-producing bacteria in our intestinal microbiota, which are known for their anti-inflammatory effect. Perfect fuel. Right now in the sports world there are a large number of products that promise to be a great pre-workout with artificial energy gels. In this case they have a moderate glycemic index, which translates into having sustained energy during training without the dreaded “bird”. But science pointed out, after analyzing triathletes, that taking raisins before exercising prevents DNA damage much more effectively than consuming equivalent amounts of pure glucose. Although beyond muscle there are other benefits, such as improvements in spatial memorywhich justify the famous Spanish saying: “For memory, corners of raisins”. Something that also seems like it belongs to older people, but that science has proven. It still has sugar. Clearly, raisins have many benefits, but it doesn’t mean you have to have a free bar of this food. And it should not be considered that way because in its composition it has natural sugars in the order of 24 to 28 grams per 40 gram serving. Although it does not behave in the body the same as white coffee sugar, since thanks to its matrix of fiber and phytochemicals, excessive consumption can cause glycemic spikes. That is why the recommendation that can be made is clear: moderation is the key.

The same day that the US threatened Spain and said it did not need the Rota base, the US invested 13 million in expanding the Rota base

by

More than 7,000 kilometers from Washington, on the coast of Cádiz, is one of the military enclaves most important of the United States outside its territory. NATO missile shield destroyers operate from there and dozens of military ships and aircraft pass each year heading to Africa, the Middle East or the eastern Mediterranean. In the midst of international escalation, that place returns to position in the center of the geopolitical board. And it reminds us again that everything has a price. Political noise and military reality. The diplomatic crisis between the United States and Spain in the wake of the war against Iran has been marked by harsh statements, veiled threats and rhetoric that suggested a strategic rupture between both countries. Washington openly criticized the refusal of the Spanish Government to allow the use of the Rota and Morón bases for operations against Iran, while Madrid defended that this war lacked legal coverage and it did not have international support. However, under this political clash a much more prosaic reality remains intact: the daily functioning of military cooperation between both countries. has barely changed. Bilateral agreements remain in force, facilities continue to operate normally and collaboration between the armed forces runs through technical channels that, although it may not seem like it, are completely separate from diplomatic noise. A threat with millions under his arm. Yes, the most revealing paradox of this situation occurred on the same day that the United States raised its tone against Spain and dropped that I didn’t need the naval base of Rota. While the political rhetoric spoke of distancing, the US Department of Defense simultaneously awarded a contract of about 13 million of euros to renew various infrastructures within the Cádiz base, from paving and parking lots to structural repairs and painting of facilities. It we count last week. The contract, awarded to a spanish company and with an execution period of five years, it was not an isolated investment but part of a broader program of modernization that will last until the next decade. In practice, while public discourse hinted at a strategic cooldown, the Pentagon was reaffirming with money and works that Rota remains a centerpiece of its military architecture in Europe. Rota as a logistical pillar. Investments are not limited to maintenance work. Washington has also approved projects much more ambitioussuch as the construction of enormous fuel depots capable of storing tens of thousands of barrels to supply naval aviation and ships of the 6th Fleet. Added to this are new missile warehousesammunition maintenance facilities, hangars for strategic transport aircraft and improvements to docks and landing strips. All this logistical reinforcement has a clear recipient: the US destroyers permanently deployed in Rota, which will soon pass five to six unitsin addition to the numerous ships and aircraft that use the base as a support point for operations in Africa, the Mediterranean and NATO’s southern flank. Thus, far from losing relevance compared to other locations such as Morocco, Rota is thus consolidating itself as one of the most important logistical nodes of the US naval strategy. Spain also expands its base. As we write A few days ago, the reinforcement of Rota is not just an American bet. The Spanish Navy has also launched its own expansion plan to solve an increasingly evident problem: the base has become too small for the number of ships it houses. Currently, American destroyers, a large part of the Spanish fleet, amphibious units and naval aircraft coexist there, in addition to ships participating in international exercises. Solution? To absorb this growing traffic, the Ministry of Defense is preparing a profound transformation of the facilities valued at more than 300 million eurosone that will practically double the port’s capacity with new docks, fuel tanks and logistical expansions. The project even contemplates modify the mouth of a nearby river and reclaim dozens of hectares from the sea to build new port infrastructure for the future F-110 frigates and to the Spanish amphibious ships. Morón and cooperation. Meanwhile, the Morón air base also continues to be part of the joint military plans. US command reports new facilities are planned ammunition storage and improvements in critical infrastructure within the Sevillian facility, with investments that could reach tens of millions of dollars. At the same time, air operations continue developing normally: American tanker planes continue to use Spanish bases for their logistics missions and, when the Spanish Government limited their use for certain operations related to Iran, the aircraft simply they moved temporarily to other European bases without altering global military cooperation. The Frigate and Iran. In fact, Spain’s own military performance in the conflict illustrates well this duality between political discourse and strategic reality. While Madrid insists that it is not participating in the offensive against Iran nor does it allow the use of its bases for that purpose, Spain has at the same time deployed one of its most advanced units in the eastern Mediterranean. The Frigate Christopher Columbusequipped with the Aegis combat system and anti-aircraft missiles capable of intercepting threats at more than 150 kilometers, has been integrated into the air-naval group of the French aircraft carrier Charles de Gaulle next to Greek ships to protect Cyprus against attacks with missiles or drones. Its mission is defensive and framed within the support of European partners, but its presence demonstrates that Spain remains fully involved in regional security in the midst of the escalation of the conflict. The diplomatic “show” and the military machinery. In short, the sum of all these movements paints a peculiar scenario, to say the least. On the surface, the declaration war between Washington and Madrid suggests deep tensions and strategic disagreements over intervention in Iran. But under this political spectacle, the joint military machine continues working normally. United States iinvest hundreds of millions in reinforcing its bases in Spanish territory, Spain expands them facilities to accommodate more ships and aircraft, armies they continue to coordinate within NATO and Spanish forces participate in military … Read more

The rain in Seville is wonderful and now it is also converted into energy with the new CSIC solar panels

by

If there is a renewable energy that has emerged in recent years, it is solar, as can be seen in this graph of the International Energy Agency. However, solar energy still has its limitations: it requires space (hence there are projects in lakes and in the open sea) and of course, it depends on whether there is sun. Yes, putting batteries can cushion that irregular supply (here Spain is a powerhouse), but a research team from the University of Seville with the CSIC has given a twist to classic photovoltaic panels and now can generate electricity with rain. Context. Solar panels lose effectiveness when full sun does not fall on them, either because there are clouds or it rains. Therefore, the ideal scenario is midday on a sunny day, but spoiler: this happens less times than you need to plug something in. Not to mention devices that need continuous and autonomous energy supply, no matter what happens in the electrical grid. The battery option allows us to satisfy the supply on demand and although now They are at their minimum pricestill involves purchasing another component, considering its useful life and its management as waste. The invention. As explains the CSIChave developed a hybrid device that allows capturing energy from both the sun and rain, and also doing so at the same time. As? With a sheet thinner than a human hair (100 nanometers) superimposed on the solar cells. It works on two fronts at the same time: on the one hand as a protective encapsulant for perovskite solar cells, improving their durability in adverse conditions. On the other hand, as a triboelectric nanogenerator: it converts the impact of raindrops into electricity due to friction. Thus, it is capable of producing up to 110 volts, enough to light LEDs or power sensors. Why is it important. Because if this technology is commercialized, it will open the doors for completely autonomous electronic devices to function without batteries or plugs. This is the case of the implementation of IoT outdoors or in remote areas without access to the electrical grid. It serves as an example of use in applications in rural infrastructure or agriculture, such as environmental sensors, weather stations, urban signage or auxiliary lighting. The innovation is not only generating energy from rain, but integrating it all into a single thin layer that solves the main Achilles heel of perovskite: its environmental degradation. In fact, science had already proven with taurine from octopuses. How have they done it. To carry out this device, they used plasma technology to deposit plasma technology in a similar way to that implemented in mobile screens. For the base, perovskite cells, a material with better efficiency and lower cost than traditional silicon, but fragile under conditions such as humidity. The use of triboelectric materials is not new: a research team from the University of Hong Kong a few years ago something similar occurred to him: the generation of electricity by the simple friction of droplets upon impact, such as static electricity generated by rubbing a balloon. Yes, but. Although technically speaking they have generated electricity, the reality is that it is high voltage but low intensity, which in practice is not even useful for charging a mobile phone. And although the perovskite is reinforced with this sheet, in the long term it is still less durable than silicon, so it still has pending issues. Likewise, there remains the great challenge of leaving the laboratory and validating these experiments in real environments. If production can be scaled to an industrial level, another challenge would arise: keeping costs low. In Xataka | Europe produces more clean electricity than fossil electricity for the first time.

If we want to increase human fertility, mice have something to tell us: fecal transplants

by

We knew that the bacteria that live in our intestine They are really positive and offer us extra protection against numerous threats from outside or even against Alzheimer’s. Now they have just added a new star function: they can help us improve our reproductive health. And all this with a simple fecal microbiota transplant. New evidence. This same month of March the magazine Nature has published an article that breaks with several scientific paradigms and demonstrates a bidirectional communication between the microbiome and women’s ovaries. The study here wanted to demonstrate that fecal microbiota transplant can completely remodel the behavior of the ovaries, reducing inflammation and even increasing reproductive success. But the most amazing thing about the experiment is not the ‘what’, but the ‘how’, since it has quite surprised the experimenters that the result has gone against what they expected. How is it possible? To understand this finding, we must first know the concept of ‘strobolome‘ which will give a lot to talk about in the coming years. In a simple way, it is a set of intestinal bacteria that are capable of metabolizing and modulating the level of estrogen, which is one of the main female sex hormones and closely related to reproduction. Until now, we knew that the microbiota played a role in almost every part of our body, ranging from digestion to our own mental health. But they wanted to go further, and in the past it was noted that they had already begun to explore how to transfer faeces from young mice to old ones, which would improve their ovarian reserve. But the best thing is that doing the opposite could accelerate the aging of the ovaries. The new study. Knowing this, this research team designed an experiment in which healthy adult mice were taken and given antibiotics to cleanse their intestinal flora. From here, they underwent a fecal microbiota transplant from mice in the ‘estropausal’ phase, which is like human menopause. What the researchers here were expecting is that if they were introduced to the microbiota of aged rats in reproductive decline, their ovaries would suffer damage. But the truth is that they were wrong. Results. The results here showed that adult females who received the “estropausal” microbiota not only did not worsen, but rather improved ovarian function and an increase in their fertility. Because? By thoroughly analyzing the organism of these ringworms, using sequencing of the genetic material of the ovaries, it was seen that the transplant had caused a massive remodeling of the ovarian transcriptome. That is, the way in which the genes in the ovaries were expressed had completely changed towards a “younger” profile. In addition, the analyzes revealed a drastic drop in the expression of genes linked to inflammation. The explanation that scientists are considering points directly to the strobolome, since it is possible that the microbiota of the stropausal mice, in its attempt to survive the natural drop in hormones of its original host, has developed brutal compensatory mechanisms. By transplanting these “surviving, super-optimized bacteria” into a young environment, they boosted the health of the recipient ovary. The future. Although in this case this effect has been seen in mouse animal modelsthe implications of this study may allow us to continue advancing treatments that can improve human reproductive health. The goal here is to be able to isolate what exactly are the specific microbial candidates or metabolites responsible for this improvement and in the future we could be talking about probiotic treatments or microbiome-based therapies to prolong fertility.
