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

Science suggests that it is a great shield against cognitive deterioration

by

In our society, the fact that grandparents end up taking care of their grandchildren throughout the day or having to pick them up from school It is something quite normalboosted mainly by the problems of conciliation familiar. This is something that has been the subject of much controversy because, when you reach a certain age, carrying the burden of having a child under your responsibility can take its toll. But now science indicates that it has important benefits. New tests. A study published this year in the magazine Psychology and Aging points out that being involved in caring for grandchildren provides a benefit to cognitive health, although it has different important nuances related to sex and time dedicated. The science behind. This study focused on data from English Longitudinal Study of Aging where More than 1,700 grandparents over 50 years of age have been analyzed. In this case, to ensure maximum precision in the results, the researchers used a matching method, comparing grandparent caregivers with those who did not care for their grandchildren, but who did share demographic and health characteristics. What did they see? With this sample on the table, what was seen is that both grandmothers and grandfathers who are caregivers showed higher levels of verbal fluency compared to the control group. Furthermore, both genders had better episodic memory compared to matched controls. In this way, it can be concluded that grandparents who take care of their grandchildren tend to show better cognitive functioning than those who do not. Quality versus quantity. One of the most revealing conclusions of the study debunks a common myth: the amount of time spent is not the determining factor. In this way, spending more or fewer hours caring for one’s grandson or granddaughter does not predict the effect it may have on brain cognition. But what really affects brain health in this case is the diversity of tasks. What was seen is that grandparents who participated in a greater variety of activities experienced better cognitive outcomes. These activities include, for example, preparing food for your grandchildren, spending time playing with them, helping them with their homework, or picking them up from daycare or school. Gender difference. Although both grandfather and grandmother showed higher initial cognitive levels when caring for their grandchildren, with the passage of time it changed. In the case of both sexes, it was observed that both verbal fluency and episodic memory improved substantially over time. But the difference is precisely in the temporal decline, causing grandmothers who have cared for their grandchildren to have a slower cognitive loss over time than caring grandparents, who maintain the same speed of loss. Because? The researchers here suggest that these differences may be due to how they relate to different genders and how they collaborate on care tasks. In this case, grandmothers tend to become much more deeply involved in the physical and emotional care of children. If we turn to the grandparents, we find that they are involved in leisure activities and often carry out care tasks in the company of the grandmothers. This way, you are not as focused on care. The limit. Logically, Maintaining multiple productive roles, such as family caregiving, can promote a more active lifestyle that positively impacts people’s cognitive functions. However, research warns that adding care responsibilities to the usual activities of these grandparents can be stressful and leave our grandparents feeling overwhelmed and with little autonomy.

NATO’s notice to shield our electrical grid

by

The blackboard hanging behind the bar at Squat 17b, a venue in kyiv, does not list drink offerings, but instead keeps a countdown of the days Ukrainians must endure the harsh winter. Inside, the bar lacks electricity and is illuminated only by candles, while customers shiver on stools drinking beer cooled by the freezing temperatures themselves. This print, described by Financial Timesis the result of an exceptionally harsh winter, with temperatures reaching -20 degrees Celsius. What is emerging in Eastern Europe is a reality that some analysts They already describe how “thermal terror”: the cold turned into a weapon of war. Russia does not merely seek to degrade Ukrainian military capabilities; It deliberately targets substations, power plants and distribution networks to make everyday life physically unfeasible. Heating, electricity and water become strategic objectives. Away from the trenches, the front line has moved to the transformers and electrical substations. In the first weeks of the year, Russian forces They have attacked the Ukrainian energy sector more than 200 times. Russia has launched coordinated waves of up to 40 missiles and 400 drones in a single night, seeking to overwhelm air defense systems. Ukraine lost up to two-thirds of its electricity generation capacity after the first months of bombing. And yet, the infrastructure resists. The new frontier of sabotage Faced with the increase in physical and hybrid threats, the European electricity industry has begun to issue clear warnings. “The last year has shown us that continuing with the current model in Europe is no longer an option,” said Leonhard Birnbaum, president of Eurelectric, in statements collected by Euronews. For the sector, security of electricity supply It has become a strategic issue. At the end of December, Poland’s security systems they detected what his Government described as “the strongest attack against Polish energy infrastructure in years.” The Sandworm group—a unit linked to the Russian GRU—managed to disable remote terminal units (RTUs) at at least 30 energy facilities. These RTUs do not generate electricity, but they allow substations and plants to be monitored and controlled. The attack affected plants cogeneration and systems that connect wind and solar farms with the grid. To achieve this, they used a destructive malicious code known as wiperdesigned exclusively to delete files and permanently render computers unusable. Polish Prime Minister Donald Tusk warned thathad it been completely successful, half a million people would have been left without heat in the middle of winter. This use of a wiper marks a qualitative leap: Russia has gone from simple digital espionage to destructive sabotage against critical infrastructure of a NATO member country. Physical espionage is added to the cyber threat under the sea. The Russian spy ship Yantaroperated by the Russian Deep Sea Research Directorate (GUGI), traveled for almost 100 days through the waters of the Atlantic and the Mediterranean. Their goal was to map and monitor the undersea cables that Europe and North America depend on for their digital communications and energy. These types of covert operations in the “gray zone” seek to measure NATO’s red lines and open the door to possible power or communications outages to force political negotiations. How did we get here? As the historic American general Omar Bradley recalled: “Amateurs talk tactics, professionals talk logistics.” For any developed nation today, the most critical logistics system is its energy infrastructure. For decades, Europe built a deeply dependent on imported fossil fuels. Dependency became vulnerability. As he remembered Bloombergthe European Union paid almost €22 billion in Russian fossil fuel imports last year, more than it provided in direct financial support to Ukraine. Changing models has ceased to be a climate issue and has become a pure survival instinct. The old continent has proven that filling its territory with renewable sources and electrifying the economy builds a much more solid structural wall than the old addiction to foreign fossils. And the shield is already working. A look at the data collected by the think tank Agora Energiewende In his latest report, Europe’s energy security on the path to climate neutrality, reveals a brutal cushion: the simple deployment of wind and solar technology during the last five years (2019-2024) avoided having to buy and burn 92 billion cubic meters of gas. However, this transformation introduces new risks. Modern power grids are more digital, more interconnected and more decentralized. According to the same report Agora Energiewendethe challenge is no longer just to ensure fuel supply, but to guarantee network stability, cybersecurity and industrial resilience. More nodes mean more potential entry points for attacks. Added to this is the technological dimension. How to collect Euronewsbetween 70% and 80% of the solar inverters installed in Europe come from Chinese manufacturers such as Huawei or Sungrow. In a highly digitalized system, hardware control also potentially implies software control. Energy as defense policy Faced with this vulnerability, Europe is obliged to treat energy security as a defense policy de facto. A coalition of defense experts, including retired military leaders such as British Lieutenant General Richard Nugee and Dutch General Tom Middendorp, has urged European governments to count low-carbon energy spending against NATO’s target of allocating 1.5% of GDP to critical infrastructure and civil resilience. In statements collected by Guardianretired Lt. Gen. Richard Nugee said, “To have a strong military deterrent we need a resilient homeland. And low-carbon energy is a critical component.” According to Bloombergthis vision is gaining ground in the European strategic debate: the energy transition is no longer just climate policy; is security architecture. The tactical key to this new defense is decentralization. Unlike large centralized plants that are easy targets for missiles, wind turbines and solar panels are much more geographically dispersed, making them significantly less vulnerable to large-scale attacks. To sustain this new model, Euroelectric proposes three fundamental pillars: Better planning: Preparedness frameworks should span the entire value chain, include all energy carriers, and anticipate long-term external threats. Massive flexibility: It will be essential to deploy new storage and demand management technologies to complement the variability of renewable energies. … Read more

Science now suggests that caffeine could be a “shield” against dementia

by

For years, the debate about whether coffee is a hero or a villain for health has swung like a pendulum between one position and another. However, science has now given a good reason for the most coffee lovers to drink even more coffee. The reason is in a new study published in JAMA which has put evidence on the table that is difficult to ignore: moderate caffeine consumption not only keeps us alert today, but could be protecting our brain for tomorrow. The data. We talk about how this is evidence that is difficult to ignore precisely because it is not a one-time survey from a weekend, but rather a Harvard research team. analyzed more than 130,000 people for four decades. Specifically, the sample that has been handled in this case has been 131,821 participants, which included health personnel, and a follow-up of up to 43 years was carried out during the years 1980 and 2023. At the end of the study, 11,033 cases of incident dementia were documented, which is what had to begin to be studied. With your diet. Once all this information is available, researchers have had to begin to cross-reference the dietary intakewhich have been updated every four years, with medical histories. Here the primary objective was to look for a pattern that related something in the lives of patients with dementia to their illness. And the truth is that they saw a fairly clear pattern: those who consumed caffeinated coffee had a lower risk of developing dementia compared to those who barely ate it. Something that other studies in the past also pointed out. Neither little nor too much. Logically, the study does not suggest that we should start drinking coffee as if it were water, since the effects of caffeine in large quantities are very harmful to health. Science suggests in this case that the greatest benefit was observed in those who consumed approximately 2 to 3 cups of coffee a day. In concrete figures, it was seen that this consumption reduced the risk of having dementia by 18% and also showed in patients a lower prevalence of subjective cognitive impairment and better scores on objective memory tests. Drink more coffee. According to this specific study, the benefit stabilizes, meaning that it does not improve further, but it does not worsen drastically in this group of patients. But other meta-analyses suggest that with consumption of more than 4 or 5 cups, the benefits can be reversed and generate other problems. Caffeine is key. One of the most interesting findings is the chemical distinction that is made, since researchers separate people who drink caffeinated coffee and those who drink decaffeinated coffee. Here the results were quite clear: decaffeinated coffee consumption is not associated with a decreased risk of dementia or better cognitive performance. This suggests that the neuroprotective effect does not come only from the antioxidants or polyphenols of the bean (which are also in decaffeinated), but caffeine is the active agent main in this equation. The effect of tea. There is a large group of people who do not depend on caffeine to stay awake, but on the caffeine in tea. In this case, tea consumption showed coffee-like associationssince drinking 1 to 2 cups a day was also linked to a reduced risk of dementia and better cognitive function. This is something that reinforces the theory that caffeine and other compounds such as L-theanine play a protective role in our nervous system. Why does it work? Although in this case the study is not focused on telling us the reasons, the authors propose a series of biological mechanisms to understand it. The first of them is that caffeine blocks adenosine receptors in the brainwhich not only makes us more awake, but could reduce the accumulation of beta-amyloid, the protein associated with Alzheimer’s when it is in large quantities. In addition to this, caffeine is also believed to reduce pro-inflammatory cytokines in the brain, mitigating neuroinflammation that precedes cognitive decline. And if we lacked reasons to defend caffeine, it is added that it improves insulin sensitivity and vascular function, two factors that, when they fail, open the door to dementia. The small print. Although variables such as tobacco, exercise and diet were adjusted for, it cannot be definitively proven that coffee causes brain protection. It may always be the case that people with early cognitive decline give up coffee because it makes them sick, but the researchers tried to control for this by excluding the first few years of follow-up. Furthermore, it must be taken into account that the participants were mostly health professionals with higher education, so the results could vary in populations with other lifestyles or genetics. Enjoy, but don’t force yourself. The person who already enjoys 2-3 cups of coffee a day has one more scientific reason to do so without guilt in this case, since it is in the “sweet spot” of neurological protection. But if there are people who do not like coffee or it makes them very nervous, there is no need to force it, since the quality of sleep and the exercise They remain the undisputed kings of brain health.

The hundreds of black dots on train and car windows are not a whim: they are a shield called ‘frits’

by

Traveling by car or train means looking around the windows. You probably don’t just look at the landscape, but at all the vehicle interior elementsthe closest being the edge of those windows. A common element on the train and on the car window is a black border with a curious pattern of dots that become smaller as the rows increase. It is not paint or an aesthetic element, but something that fulfills a crucial technical function to protect the integrity of the glass. They are called ‘frit band‘ either ‘frits‘, and it is one of the most important passive safety elements that these vehicles have. The Science of Car Window Blackheads Although it seems like it, these dots are not paint: they are ceramics baked at very high temperatures, which fuses with glass during manufacturing of the same. He process It is most curious, since first the still hot black ceramic paste is applied to the edges of the glass, and then it is baked together with the glass in the tempering and bending process. In Xataka In 2001, Renault launched a car ahead of its time: it was a miserable failure that now has another chance It is a structural element of glass and this process involves a permanent bond that does not wear over time. The dot pattern motif, known as “gradient matrix”it is not a whim either, but a solution to something that could spontaneously break the car window. Black glass absorbs much more heat than clear glass, and this is something you can easily check on a sunny day: the black band will be hotter than the rest of the glass. When the temperature is extreme, and on trips where the moon can being hit by small stonesif there were an abrupt temperature transition between the black border and the transparent area, stress points would be created that could cause cracks. That’s why they pulled out that gradient that works like a processor heatsink: creates a thermal transition zone which distributes heat more evenly. It is something that provides protection to the glass, but they serve something else: to help the bond between the chassis and the glass. On the perimeter of the crystals there is glue that joins the elements, and the ‘frits’ have a rougher texture that allows a better adhesion from glass to chassis. Also, being black, they protect the glue against ultraviolet rays, maximizing its durability and the security of the union of the components. A detail from Jeep, which introduced an Easter egg in these frits In the end, what might seem like a simple aesthetic element fulfills an important safety function. In the train, this adhesion and thermal dissipation, and in the car, added to the above, greater resistance of the moon to shocks. In some cars it has been used to place a nod, and the fact that they are circles and not another geometric element has an aesthetic part, but also functional because it makes us overlook them while driving. It is one more example of all that everyday technology that surrounds us and that perhaps we always wonder if it would have some function, but once that initial curiosity passes, we forget to look.

Faced with the threat of an “orbital Pearl Harbor”, Europe has made the same decision as the US: shield space

by

The race to militarize space has accelerated to an extent unprecedented since the end of the Cold War. The reasons are several, but the main one is driven by the combination of explicit russian threatscovert sabotage and an international architecture incapable of containing the emergence of atomic weapons out of the atmosphere. The last one to join: Europe. The war in orbit. Moscow not only has reactivated its classic nuclear discourse, but has opened a second front in low Earth orbit through the development of anti-satellite systems equipped with nuclear warheads that openly violate the Outer Space Treaty. In this context, European and North American experts match in which the Kremlin is lowering the threshold for the use of tactical nuclear weapons both on Earth like in spacewhile experimenting with platforms capable of camouflaging orbital bombs designed to disable satellites essential for the economy, defense and communication. Thus, the very idea of ​​a “Space Pearl Harbor” (a nuclear explosion that destroyed thousands of satellites, blinded entire continents and turned low orbit into a radioactive dump for generations) has forced Europe to abandon the romantic vision of an exclusively civil space and enter a new strategic reality which combines deterrence, diplomacy and operational preparedness. The bet of the old continent. This turn has crystallized in a historic decision: For the first time, European Space Agency countries have approved funding a program designed explicitly for military functions. He ERS projectconceived as a “system of systems” equipped with surveillance capabilities, secure navigation, encrypted communications and Earth observation, marks Europe’s entry into the club of actors who recognize that their future security depends both on what happens on the ground and what happens hundreds of kilometers above it. The approved financing (1.2 billion euros with more to come) comes accompanied by an unprecedented political mandate that redefines the concept of “peaceful purposes” at a time when China multiplies its space capabilities and Russia turns orbit into a space hybrid pressure. The magnitude of the support, bordering 100% of what was requestedreflects an internal consensus: without its own capabilities, Europe would be a vulnerable spectator in a conflict that would be decided by the speed and resilience of its satellite constellations. The French and German response. On this new board, France and Germany have assumed a central role both for its industrial capacity and for its newly adopted conviction that the wars of the future will begin (or be decided) in space. Paris has invested 10 billion euros in its new Space Command, oriented to military operations in orbit, to shield satellites against kinetic attacks and to promote an interoperable architecture with NATO. Berlin, for its part, has announced an investment of 35 billion until 2030 to reinforce its own Space Command, develop guardian satellites and equip itself with advanced early warning systems. Both countries have publicly assumed that orbital infrastructure is so critical such as energy or digitaland that any Russian aggression could paralyze not only defense, but European civil society as a whole. National security is no longer decided solely on the eastern land border, but in a three-dimensional environment where the loss of a single satellite node can destabilize entire sectors. Nuclear beyond the atmosphere. Analysts agree that the most feared scenario is not a specific attack against specific satellites, but the detonation of a nuclear charge in orbitcapable of generating devastating electromagnetic pulses and cascading space junk that would render low orbit useless for decades. Historical precedents, such as try Starfish Prime that destroyed a third of existing satellites in the 1960s, serve as a warning of what it would mean to repeat a similar experiment today, with more than 10,000 active satellites. Such an explosion would kill astronauts, destroy global navigation infrastructure, fossilize the digital economy and cause a domino effect that could move the war from space to Earth. Although some experts hold While Moscow would only resort to such action in a scenario of terminal collapse, the mere existence of these capabilities forces Europe to prepare for a type of conflict that would break the traditional limits of deterrence. Political pressure and a new order. Fear of an orbital conflict has reactivated debates on nuclear disarmamentboth in the United States and in Europe, where legislators are promoting initiatives to revitalize multilateral negotiations that have been stagnant for decades. At the same time, ESA has achieved a record budget (22.1 billion euros) that not only finances its transition towards space security, but also promotes scientific and commercial programs, such as reusable rockets, Martian exploration or new astrobiological missions. This growth, supported by Germany, France, Italy and Spain, reflects the strategic convergence between defense, research and technological sovereignty. In the new scenario, Europe seeks not to be a secondary actor in the face of spatial duopolization between the United States and China, but to develop real autonomy that reduces dependence on private platforms like starlink or American systems such as the space interceptors of the Golden Dome. Militarize space. If you also want, the intersection between russian threatsAmerican technological advances and the European strategic awakening marks the beginning of a stage in which the Earth’s orbit is consolidated as the new global scenario military competition. What was once a scientific and commercial domain has become a space where the resilience of entire societies is decided. He ERS projectthe expansion of national space commands and the growing funding of dual capabilities make up a defense ecosystem that seeks to avoid a conflict that no one wants to imagine. And in that scenario, Europe seems to have understood that the only way to deter orbital escalation is to demonstrate that it has the same means to resist it, respond to it and recover.
