A municipality in Cáceres has waited more than 30 years for its bridge with Portugal. After moving wind and tide, it is already on its way

by

Cedillo, the westernmost town in Extremadura, has been separated from its Portuguese neighbors for more than thirty years by a river that, paradoxically, has always united them. The solution is easy: build a bridge. The issue is that its approval and construction has been in the works for years. Now it seems that things are finally moving forward. The problem. Cedillo (Cáceres) and Montalvão-Nisa (Portugal) are separated by just 13 kilometers in a straight line. But by car, any trip between both towns requires a detour of between 100 and 120 kilometers. The reason: the dam that Iberdrola manages at the confluence of the Tagus and Sever rivers. Until 1995, residents on both sides could cross it freely. That year, with the entry into force of Schengen AgreementIberdrola closed access citing security reasons. Since then, it has only opened on weekends, with a security guard and at controlled hours. “We are brother peoples absurdly separated,” counted in 2021 to El País the mayor of Cedillo, Antonio González Riscado, who has been in office since 1987. How did it get here? The bridge project has been circulating through offices and negotiation tables for decades without finally coming to fruition. In 2011, the Provincial Council of Cáceres, then in the hands of the PP, renounced some European funds destined for the work, according to account The Country. When the PSOE recovered the institution in 2015 and requested them again, Europe had already denied them. The project became a political bargaining chip for years. The turning point came in March 2023, when the Ministries of Transport of Spain and of Territorial Cohesion of Portugal signed a joint declaration committing to promote the initiative. Just over a year later, in October 2024, both governments signed in Faro an international agreement which established the definitive legal framework to build the bridge. According to this agreement, Portugal assumes the design, construction and financing of the main structure, while Spain facilitates the permits and procedures in its territory. The works have already started. In October last year, the machines began to move on the Portuguese side with the first land preparation work. The award went to the company Alexandre Barbosa, according to counted The Extremadura Newspaper. The bridge will be about 160 meters long and 11.5 meters wide, with two twin concrete arches that avoid placing pillars in the riverbed. In fact, as the media reports, this last technical solution was key for the bridge to obtain the favorable Environmental Impact Declaration. The total cost exceeds 19 million euros. Spain does its part. In November of last year, the Ministry of Transport and the Government of Extremadura they signed an agreement to coordinate the work on the Spanish side. The Board assumes the bidding, construction and financing of the accesses to the bridge in Extremadura territory, with an estimated budget of just over 5.1 million euros distributed between 2025 and 2028. Once the work is completed, the infrastructure will become the property of the Board of Extremadura, which will also be responsible for its maintenance. What this means for the area. The bridge is going to solve a problem that has been on the lips of the surrounding towns for decades day after day. Just like counted El País, there are residents of Cedillo who have been hearing about the bridge all their lives and whose lives have been conditioned by that barrier. According to collect El Periódico, the bridge will also shorten the distance between Cáceres and Lisbon by about 70 kilometers and half an hour. “It is a bridge that we need no matter what,” the mayor of Cedillo told the media. What remains pending. On the Spanish side, the access to the bridge was still pending bidding when Portugal already had the machines running. Both countries will coordinate the work through a Joint Technical Commission. The agreement between the Ministry and the Board has a maximum validity of four years, extendable. If the deadlines are met, Cedillo could have his bridge before the end of the decade.

For years we blamed testosterone for men living shorter lives. Now we know that the culprit is a chromosome

by

For decades, biology has observed an incontestable demographic fact: women live longer than men. It has often been blamed lifestyleto testosterone or to the greater male propensity for risky activities. However, science has found a much more subtle and genetic culprit that we carry in all our cells and that literally we start to lose as we get older. A genetics class. In a very general way, we must remember that all our genetic information is collected in 46 chromosomes which are found within the nuclei of our cells in pairs. But there is a part of all these chromosomes that define us as men or women: The presence of two X chromosomes defines women and the presence of one X chromosome with one Y defines men. Although there is great genetic complexity behind something as redundant as a pair of chromosomes, what interests us in this case is that science has seen a effect called mLOYwhich is literally the loss of Y chromosome mosaic in men. And different scientific articles suggest that it is not a simple side effect of getting older, but rather it is a “silent killer” that explains much of the longevity gap between the sexes. The runaway chromosome. For a long time, the Y chromosome was considered the “little brother” of the genome. Small, with few genes and almost exclusively responsible for determining the male sex with no other known functions, almost all of which fall on the X chromosome of considerable size. But the truth is that we were wrong, and the Y chromosome has great importance in the adult life of men. The mLOY phenomenon. This occurs when the cells that are in charge of manufacturing the blood elementslike erythrocytes, platelets, or lymphocytes, suffer errors when dividing and lose the Y chromosome. Something that generates a “mosaic” in our body, that is, some white blood cells have the Y chromosome while others do not. But what is disturbing is the frequency with which it occurs, since, according to the data reviewed, this is something that has been detected in 40% of men at age 60 and in 70% of men at age 90. There is damage. Until recently, it was believed that losing this chromosome was benign and normal, a simple “genetic gray hair.” But the evidence accumulated between 2022 and 2025, including massive UK Biobank studies and the recent German studio LURIChas set off alarm bells: losing the Y chromosome is not harmless and has important side effects. The heart. One of these side effects is precisely heart failure, which is a very prevalent disease in the elderly. Here science has been able to see that, by eliminating the Y chromosome in mice, the animals rapidly developed cardiac fibrosis. That is, their hearts were filled with scar tissue, becoming rigid and, therefore, having great difficulty pumping blood. But it is not the only disease that occurs, since in the United Kingdom Biobank, men with mLOY in more than 40% of their white blood cells had a 31% higher risk of dying from cardiovascular causes. And even the LURIC study published last year, carried out on 1,700 men, found that the mLOY effect increased the risk of fatal heart attack by almost 50%. More diseases. Beyond the heart, the impact of losing the Y chromosome also affects our body’s defense system to be able to combat different threats. Among them we have cancer, since the immune system needs the Y chromosome to effectively monitor the tumor cells that arise. Its loss is associated with a worse prognosis in bladder cancer and other solid tumors, since it is as if our body’s security guards had gone partially blind. In addition to cancer, the frequency of mLOY has also been seen to be up to 10 times higher in patients who have Alzheimer’swith studies showing an almost 3 times higher risk of developing the disease. The COVID. During the pandemic we saw that older men died much more than women without fully understanding why. We now know that the loss of the Y chromosome increases 54% risk of fatality for being infected with COVID in the elderly, finally offering a biological explanation for this bias. Is there a solution? It may seem depressing to know that a part of our DNA decides to abandon us and cause us so many problems, but in reality, it is a hopeful finding. And it is hopeful, since, seeing that the loss of the Y chromosome is a direct cause of a disease, therapeutic doors open. In experiments with mice, it has been seen that treatment with an antifibrotic drug was able to reverse the cardiac damage caused by the loss of the chromosome. This means that the mLOY effect can be used as a marker in a blood test, as happens with cholesterol, to predict a patient’s cardiac risk and to be able to give preventive treatments to delay it and improve the patient’s quality of life.

China’s brutal dominance in rare earth production in the last 30 years, in a revealing graph

by

There are few strategic natural resources as important as gas, gold or oil, but there is one that is less known and that is decisive in practically any industry and therefore, also in geopolitics: the rare earthwhich are neither earths nor rare (in fact, they are a list of 17 metals). The state that has enough rare earths in its territory and the capacity to extract them will have much to gain to become a power. Well, if you can cough China, the absolute leader in rare earths so much in reserves as in production. A picture is worth a thousand words. But today the power of China is discussed is one thing and another if the Asian giant started by winning the game. Spoiler: no. The United States Geological Survey It has a very complete database where to visualize production by country from 1994 to the present (among other information), but more than a table, it is better seen with images. Thus, at a glance you can see its beastly hegemony in this chart from Visual Capitalist from 1994 to 2024. 30 years of rare earth production. Visual Capitalist An animation still counts more. The Visual Capitalist illustration shows Chinese superiority, but the evolution of rare earth production by country is better seen with an animation showing its meteoric rise because yes, the global rare earth industry has been profoundly transformed in the last 30 years. In just three decades, China has gone from having a 47% quota to almost 70% of the 400,000 metric tons produced today (by the end of 2024). Or what is the same, going from manufacturing 31,000 metric tons to 270,000 metric tons, something that can be seen in this animation by Global Times and Valiant Panda: Tap to see the animation. Production by country of rare earths from 1994 to 2024, Global Times How America Lost Control. It’s worth stopping the animation at the beginning, because in the 90s the United States was the world’s largest producer of rare earths and Mountain Pass was its main plant for obtaining them. Its average extraction was around 20,000 – 22,000 tons. And then, in 1997, came the Mountain Pass environmental disaster: a burst pipe in the eponymous mine that contaminated the Movaje Desert with toxic radioactive waste. Between the disaster and the subsequent lawsuits, production suddenly fell to 5,000 tons between 1998 and 2002. It would then fall to 0 in the 2000s. It would be in the 2010s when it began to recover: now the United States is around 46,000 metric tons. As Rocío Jurado sang, now it’s too late, lady: it was also in the 90s when China went into steamroller mode. The unstoppable rise of China. That China has come to dominate world production hides several keys. The first, the ability of its suppliers to offer lower prices Thanks to state aid, laxer environmental standards and cheaper labor made possible costs that the West could not cope with. China had the resources, but its victory came because it was able to build an entire industry while the rest of the world watched. Producing the raw mineral is only the first step, then it must be separated to achieve a high degree of purity (between 95 and 99%, depending on the application) in a complex, expensive hydrometallurgical process that, as we have seen, leaves radioactive waste along the way. Where it still dominates more: refining. Because although China has a share of almost 70% of world production, its dominance is even more overwhelming in refining: it produces around 90% of world refining. In fact, other countries such as Australia or the United States extract minerals, they turn to China for refining. If there is no refining industry at the level of extraction, there is no sovereignty. Other faces. Trump wants to step on the accelerator of national mining and expedite permits, the EU also seeks its strategic sovereignty with laws such as the Critical Raw Materials law and its application in places like Per Geijer’s Swedish megamine. We have already talked about Australia, which at least until this year It will depend on China for refining those 16,000 metric tons that have been around in recent years, but there are other countries that have joined the race. But while the Global Times animation focuses on great powers, the Visual Capitalist graph reveals new players in the industry such as Myanmar, Thailand or Nigeria, especially focused on more scarce and valuable elements. However, their supply chains are unstable and have their own regulatory and geopolitical risks.

We have been believing for years that intermittent fasting is the definitive weapon to lose weight. Science has another idea

by

During the last years, the intermittent fasting has gone from being something exceptional to becoming a nutritional strategy that there is more and more talk and that it has more followers behind it. And it is no wonder, since the promise is quite seductive as it does not focus on what you eat, but on when you eat, activating different metabolic switches to accelerate fat burning. Although there are also detractors behind. New data. The Cochrane library, considered a great world reference, published a few days ago a great review about intermittent fasting that acts as a bucket of cold water, since it suggests that this diet does not offer superior benefits to conventional weight loss diets. The backup. We are not talking about a small study whose validity can be questioned, but in this case the Cochrane researchers analyzed 22 randomized controlled trials that added up to a total of 1,995 participants. overweight or obesity. The objective here was to compare different fasting modalities, such as going 16 hours without being able to eat with eight hours of eating, fasting on alternate days or 5:2 diet compared to classic calorie restriction or inaction. What they found is that, when pitting intermittent fasting against regular dietary advice, the difference in weight loss is virtually zero. The data. Getting into the matter, when intermittent fasting was compared With standard calorie-restricted diets, the mean difference in weight change was a minuscule -0.33%. This difference can translate into that intermittent fasting may result in little to no difference in weight loss with the traditional method. Regarding quality of life, such as the feeling of energy, no difference was seen and, regarding the levels of total cholesterol, HDL cholesterol and triglycerides, fasting did not prove to be a panacea either, yielding results of “little or no difference” compared to the control diets. The small print. One of the most critical points of the Cochrane review is the certainty of the evidence, which they rated mostly as “low” or “very low.” This does not mean that the studies are poorly done, but rather that there are important limitations, such as risk bias, inconsistency in results, and lack of precision. But there is one fact that should worry anyone who decides to opt for this diet independently, without medical advice, since, although the evidence is uncertain, some studies pointed to associated side effects specifically to fasting. These include headaches, nausea, cold intolerance or even insomnia and lack of concentration. What is not yet known. Perhaps it is the most revealing thing about this scientific study, since there are still many unknowns surrounding intermittent fasting that invite further research. In this case, none of the 22 studies included data on “patient satisfaction,” which is important because we don’t know if people prefer to go hungry for a few hours in exchange for eating more later, or if they hate the process. And being comfortable with a diet is essential so that you don’t abandon it halfway through. In addition to this, none of the studies pointed to the relationship that may exist in chronic diseases that require significant dietary control, such as diabetes, and which is very common in the population. But one of the big problems in science today is duration, since most studies lasted less than 12 months. We don’t know if fasting is sustainable or safe beyond a year. It is not a miracle diet. What we do know is that intermittent fasting works, but the key point is that It is not superior to the tools we already had as a calorie restriction accompanied by a balanced diet and exercise. For the average patient, this is actually good news: it means that the The best diet is the one you can stick to. If someone finds it easier to skip breakfast with a 16:8 fast than to count calories at each meal, fasting is a valid tool. But if fasting causes headaches, you’re not missing out on any “magic” metabolic benefits from eating three times a day. Although in this process the most important thing is always to be advised by personnel who are qualified in nutrition to be able to have the best dietary plan, to have real objectives and, above all, not to get frustrated along the way.

Registrations are plummeting for the first time in 20 years

Computer engineering is a classic among the most in-demand jobs in recent years. In fact, without going any further, it was the university degree with the most job opportunities in 2025. However, it faces an abyss: that of a future with AIwhich we have already seen is beginning to wreak havoc among junior profiles. Generation Z seems to have noticed and after two decades of continuous growth, enrollment has begun to decline in the mecca of computing: the Universities of California. Context. For decades, studying computer science has been a true bastion of employability, whether choosing for the race as in their variants in FP version. That is to say, if you wanted to study a career that would guarantee you a specialized job, something especially interesting for the middle and lower classes, in computing you would find real life insurance. The San Francisco Chronicle has captured the data of the set from California universities in a graph showing that not even the 2008 financial crisis or the COVID-19 earthquake managed to undermine its appeal: computing seemed armored against crises. Computer science enrollments on California public university campuses since 2000. Data: University of California Something is changing in computing. More specifically, data from the University of California shows that 12,652 computer science degree students have chosen computer science this year, this is 6% less compared to 2024 and 9% less compared to 2023. It is true that it is almost double what it was a decade ago, but the decline is clear taking 20 years ago as a reference, the time when there was the last (slight) decline. The data in question does not come from a specific university or from any group: we are talking about the small group made up of the public universities of California, which include illustrious ones such as UCLA, Berkeley or San Diego. Therefore, Stanford does not appear in these data as it is private. Why is it important. Because the perception of computing as a choice that guarantees success is no longer what it was: on the one hand, because AI is taking away opportunities who starts to work and for another, for the big layoffs What we are seeing in big tech. Furthermore, it has brought a paradigm shift: parents no longer encourage studying computer science as much as they do other more classic and tangible engineering: electrical, mechanical… according to what personnel related to admission to these universities know, whose statements collects the Californian media. And this is not just happening in California, but it is a global phenomenon. The Universities of California are leading the way: what happens at Berkeley or UCLA is a preview of what we will see soon here as well. Without going any further, the University of San Diego got ahead last year creating an AI career Let’s see how it goes. Spoiler: it was a total success, like acknowledges Steven Swanson for TechSpotthe department head and computer science professor. kitchen ear. A deeper analysis of data from California universities shows that it is not that there are fewer technology students, it is just that they are changing their choices towards more specific and emerging ones. Between the success of emerging and specialized programs and these data, universities already have a pending issue on the table: carrying out a curricular transition. Classical computing is becoming a transversal subject and not the final destination, that is, it is no longer so important how a tool is built (chopping code), but rather how to think and how to validate it in a future in which its students will have to work side by side with AI.

Marie Curie died 92 years ago. Your personal notebooks are still buried under layers of lead for a good reason

by

If you visit the basements of the National Library of France (BnF) and you want to look at some of the bibliographic gems that are kept there, you will most likely be forced to respect a series of measures, such as wearing gloves or handling the books in perfectly controlled conditions. The objective is obvious: protect the volumes. From you, from excessive exposure to light, from degradation. Things change if what you want to read is one of the notebooks that Marie Curie scribbled in her laboratory. In that case it is you who they must protect. Literally. The fact that there are dangerous publications may be a controversial statement that may or may not be shared, but in the case of the folios handwritten by the famous Franco-Polish scientist, it leaves little room for debate. Despite Madame Curie He died in 1934, almost 89 years ago, his notebooks continue to cause concern among archivists. and it is quite normal so be it. When Marie Salomea and her husband, Peterinvestigated in their laboratory with uranium, little was known about the potential damage of radiation, so they did not apply the basic safety measures that govern any radiological task today. So things—supports the American Council on Science and Health (ACSH)— “no wonder his workspace and notebooks became contaminated.” Pierre and Marie Curie, in the laboratory, around 1904. To avoid possible risks, the handwritten notebooks are kept in the basements of the National Library of France inside special boxes, made up of several layers of lead. Not only that. As detailed in 2021 by the BBC networkthe French institution requires researchers who want to handle the notebooks in person to first put on some protective suits specials and, of course, that they sign a document in which they exempt them from any responsibility. Is such misgivings justified? When reading requires a special suit For their research, which led to the discovery of polonium and radium, the Curies accumulated, crushed and manipulated enormous quantities of minerals containing uranium in their laboratory. He knowledge about natural radioactivity It was very recent at the time and the couple, who contributed to their research, were unwittingly exposed to its harmful effects. Themselves and, of course, all the material they used. Including notebooks of notes. To understand the conditions under which they worked, it is good review the notes by Marie, collected by Philipp Blom in ‘The years of vertigo: Europe, 1900-1914’: “One of our joys was entering the workshop at night; everywhere we saw the faintly luminous silhouettes of the capsule bottles containing our products. It was a beautiful sight and always new to us. The glowing tubes looked like dim fairy lights.” It was not strange, they say, that the pair of scientists carried flasks with polonium and radium in their coat pockets or kept them in their desk. Marie herself ended up dying in 1934 from a aplastic anemia which was probably caused by his frequent exposure to radium samples and polonium. “Taking into account the half-life of 1,600 years of the radius and the sensitivity of current radiation detectors, it is also not surprising that this contamination is still detectable today,” comments the ACSH in an article dedicated to the topic. The experts, BBC specifiescalculate that given that on average radium atoms take about 15 centuries to disintegrate, it is not unreasonable to think that the notebooks should remain in their lead box during that period. The National Library of France is in any case not the only one to preserve Curie’s notebooks. The Wellcome Collection It also has a volume, digitizedwith notes on experiments and radioactive substances and sketches. The volume dates from between 1899 and 1902 and was written in Paris. To avoid scares in 2014 The Aurora firm examined the material and concluded that it was contaminated with radius-226. The ACSH states in any case that the volume “does not represent an appreciable risk.” Fortunately, the notebook can consult now from homeonline, or even downloaded in PDF. The theme of “the contaminated notebooks” of Curie generate so much interest that it even has your own entrance on the website Marie-curie.eu, focused on the figure of the two-time Nobel Prize winner, and numerous articles have been written on the subject. Notebooks are not the only ones in a similar situation. The BBC explains that the house south of Paris where Marie Curie worked until 1934 is also affected by the radiation levels generated during her experiments. The block has even earned the ironic nickname of “Chernobyl on the Seine”. When he was buried in Paris Pantheoneven Marie Curie herself ended up in a lead sarcophagus almost an inch thick.

Carrefour is going to open 750 stores in Spain in the next four years. But not as we know them

by

Carrefour has announced 750 openings in Spain and not because business is going especially well. He has announced them because the model that made him great (the suburban hypermarket) has been losing steam for a while. This strategic plan until 2030 is, above all, an adaptation to the reality of the modern consumer. The background. Carrefour was one of those who popularized a way of shopping that dominated the retail European for a time: the hypermarket. A huge area on the outskirts, with free parking and the idea of ​​having everything under one roof. Saturday shopping as a family ritual. That model worked while life revolved around cars and rigid schedules. But habits have been changing, and with them the business. The contrast. The 750 planned openings are not hypermarkets. They are mainly small-format, urban convenience stores (Carrefour Express), many operated by franchisees. The kind of place where you walk in on the way home, grab what’s missing, and in ten minutes you’re done. Not where you spend much more time filling a car. In Spain, the only format that grew in 2024 was precisely this: 62 new Express stores compared to zero net openings in hypermarkets and large supermarkets. Yes, but. Growing in convenience is easier to announce than to execute. The margin per square meter is lower, the competition is intense, from Dia to the regional chains; and the franchise model involves relying on third parties to maintain standards. Alexandre Bompard, CEO of Carrefour, has admitted that part of the growth will come through acquisitions, because the Spanish market “is fragmented.” In other words: you have to buy to gain scale, and that costs money and time. Meanwhile, Lidl, with almost a 7% share, threatens to take second position from Carrefour in the Spanish market, where the French group has lost 0.7 points in a year and stands at 9%. Very far in any case from Mercadona. The big question. What is done with the 206 hypermarkets that Carrefour has in Spain? The plan talks about converting up to 10% of its surface towards growth categories, such as pets, personal care or financial services. It is a reasonable solution, but it patches the format more than transforms it. Carrefour’s real bet is to build a parallel business to the hypermarket, smaller and more urban, that grows while the large one stabilizes. If you succeed, you will have read the moment correctly. If not, you will have spent a lot of money chasing rivals who already have an advantage.

The Canary Islands have been suffering total blackouts for years. Their salvation is a beast of engineering 1,145 meters under the sea

by

A month ago, the destabilization of an old generator at the El Palmar thermal power plant in La Gomera caused a dramatic “cascade effect” that left more than 15,000 people without electricity, and without mobile coverage. This incident showed the extreme fragility from living in an isolated electrical system. However, the solution to this historical vulnerability no longer looks to the sky, but to the depths of the Atlantic. To overcome the abrupt volcanic orography and the extreme pressures of the Canary Islands seabed, engineering has had to design an “umbilical cord” unprecedented in the world, marking a before and after in the history of the archipelago. The end of isolation. In an effort to protect supply, Red Eléctrica de España (REE) has officially inaugurated the underwater interconnection between La Gomera and Tenerife. As confirmed by the REE itselfthe magnitude of the project translates into historic figures: an investment of 145 million euros for the cable laying, to which are added another 32 million destined for the two link substations located in Chío (Tenerife) and El Palmar (La Gomera). It is not a capricious work. How they collect local mediathe Canary Islands have suffered nine major “energy zeros” (total blackouts) since 2009. Tenerife and La Gomera have been among the islands hardest hit, so this infrastructure was born as a vital antidote to darkness. More than light. The implementation of this system completely alters the energy paradigm. As indicated ANDldiario.esboth islands cease to be solitary island systems and become a single network. From now on, if the rubber plant fails, Tenerife will inject energy instantly to avoid a blackout, and vice versa. But the scope of the work transcends mere security. As explained in detail in the REE statementcable is the key to decarbonization. La Gomera will now be able to generate much more renewable energy – mainly wind – than its population consumes. This green surplus will not be lost, but will travel along the seabed to Tenerife, drastically reducing the burning of fossil fuels on both shores. The technical challenge: engineering to the limit. Connecting two volcanic islands separated by abyssal trenches is not an easy task. As emphasized The Daythe 36 kilometer length of the cable descends to 1,145 meters below sea level. This extreme depth makes it the deepest tripolar alternating current link on the entire planet, snatching the record that linked Crete and the Peloponnese since 2021. To withstand the weight and crushing pressure of the ocean at these levels, engineering had to reinvent itself. To do this, they had to discard the traditional use of steel and lead, opting instead for an ultralight synthetic material armor and an insulation based on ethylene and propylene rubber. Caring for the environment was also a priority. In order not to destroy coastal biodiversity or alter shallow volcanic beds, from The Confidential detail that it was used the “directed drilling” technique: an underground microtunnel that allows the cable to exit to the sea hundreds of meters from the beach. Likewise, the terrestrial substations use GIS (gas-insulated) technology to occupy the minimum possible space, and their buildings have been camouflaged imitating greenhouses and agricultural terraces to integrate into the landscape. Laying underwater bridges. The milestone of La Gomera and Tenerife is just the beginning. Future planning, as pointed out The Daycontemplates the colossal challenge of joining Fuerteventura with Gran Canaria, an even greater challenge given that the distance between the two exceeds 100 kilometers. Parallel to the electrical revolution, the Canary Islands are experiencing an unprecedented leap in their telecommunications. As these local media detailthere are more projects like BASE 6, promoted by the public company Canalink. This is a new 328 kilometer fiber optic cable with a budget of 19 million euros that will link Tenerife with El Hierro, landing through a drilling on Tamaduste beach. This data highway, with a capacity of 5 terabits per second, seeks to eradicate the digital divide on the most remote island, guaranteeing services such as telemedicine or online education. The invisible network. The Canary Islands not only look inward. As contextualized by OCTSI (Canary Telecommunications Observatory), the archipelago has been functioning for decades as a global strategic node, surrounded by historic fiber rings and international connections such as Telefónica’s PENCAN cables, currently in the process of renovation. However, this strategic position has its geopolitical edges. An extensive report from my colleague for Xataka focuses on network extension from Canalink to Africa. The Canary Islands are financing a cable to the Moroccan city of Tarfaya with European funds. The problem lies in the fact that Morocco intends to extend this infrastructure towards Western Sahara, a movement that clashes head-on with the rulings of the EU Court of Justice and that threatens to place Spain at the center of a complex diplomatic and legal conflict with the Polisario Front. Overcoming geographic isolation. At 1,145 meters under the scrutiny of the waves, where sunlight does not reach and the pressure is unbearable, the heartbeat that unites two islands now runs. The Canary Islands are managing to transform their greatest geographical weakness—fragmentation and isolation—into a true global showcase of technological innovation. Little by little, the old and noisy combustion engines give way to a future that will be inescapably green, and deeply interconnected.

2,000 years ago the philosopher Seneca said that anger was a burden for people. Today we know that he was wrong

by

Seneca did not like irritated people. Almost all of us will agree with him on that. The Hispanic philosopher, however, was so angry about the angry people (apparently the irony) that about twenty centuries ago he dedicated an entire treatise to them. (‘Of Anger’)a work in which he reflects on what anger is, its causes, effects, nature, whether or not it is manageable and how we should act when we feel that we begin to hyperventilate and all kinds of expletives gather in our throats. The problem is that Seneca wasn’t entirely right. “Somber and wild”. Seneca’s work does not leave much room for interpretation. It is titled ‘De Ira’ and throughout its three volumes (available online in the Cervantes Virtual Library) the author is dedicated to telling us about what it is, where it comes from and, above all, how to act in the face of anger. His words connect with the best Stoic tradition when advising us to flee from the slavery of impulses and embrace a serene and reflective attitude. “You demanded of me, dear Newbie, that I write to you about the way to control anger. And I believe that, not without cause, you fear very mainly this passion, which is the darkest and most unbridled of all,” Seneca starts in the first chapter of his treatise, addressed to his brother. “The others undoubtedly have something quiet and placid, but this one is all agitation, unbridled resentment, thirst for war, blood, torture, outburst of superhuman fury.” A form of madness? If the above is not enough to make Seneca’s position clear, throughout the following pages he expands on explaining the meaninglessness of anger. The reason? It leads us to forget ourselves in order to harm others, “throwing ourselves into the midst of swords.” “For this reason some wise men defined anger by calling it ‘brief madness’. Powerless like that to control itself, it forgets all convenience, ignores all affection, is obstinate and stubborn, deaf to the advice of reason, agitated for vain causes.” follow the author. The work is full of reflections that go along that same line, but there are a passage especially eloquent in which Seneca warns us of the extent to which anger can distance us from our purposes, even from who we are: “Man was born to help man; anger for common destruction. Man seeks society, anger isolation; man wants to be useful, anger wants to harm; man helps strangers, anger hurts even the most intimate friend; man is willing to sacrifice himself for other people’s interests, anger rushes into danger in order to drag another along.” It makes sense, right? More or less. Anger may condition our behavior, making us act differently than we would if we were calm, but… Is that necessarily bad? Is anger always “the darkest” of passions, as Seneca says? In the 21st century there are authors who are not so clear. one of them is David Robsona popularizer who has published ‘The intelligence trap’among other psychological essays. In July 2020, in the middle of the pandemic, with thousands of people feeling helpless and frustrated at not being able to move freely, Robson published an article on BBC in which he talked about just that: the positive side of getting angry. Its title is also transparent: “The benefits of anger: the good side of doing things with anger.” Beyond its provocative tone, Robson’s essay is interesting because it summarizes recent scientific research that suggests that acting out of rage may not be as bad as Seneca believed. A source of energy. Which defends Robson is that, beyond its destructive power (something that is not denied) anger can have certain advantages. “Anger and related emotions, such as frustration or irritation, can also have advantages, as long as we know how to channel the energy that arises from them.” Its premise is very simple: instead of investing energy and time in repressing anger, why not try to channel that feeling, take advantage of it, use it as a source of motivation? It may sound crazy or self-destructive, but the author recalls studies that raise the same idea: how disturbance (well managed and channeled) can help us in certain contexts. Angrier, higher performance? Robson’s approach is not far from that of Britt Q. Ford, a professor at the University of Toronto, who define anger as “a mobilizing emotion that is physiologically activated”, generating an activation that can be used for certain physical objectives. He doesn’t talk just to talk. Years ago, a group of scientists found that, when they imagined annoying scenes, the subjects of their experiment performed certain physical tasks harder and faster. Their performance seemed to increase when they felt frustrated because they channeled it through physical activity. Robson cites more studies that show similar effects in athletes who throw balls and jump or even among players in the NBA and National Hockey League in the United States. When suffering flagrant and frustrating fouls, players seemed more motivated to score points. “The angrier they got, the faster they threw or the higher they jumped.” Interesting, but with limits. Of course, it has nuances. a study published in 2011 on “anger, aggression and athleticism” found that “a greater number of technical fouls” usually precedes greater “success in aspects of the game that require power and energy, such as making field goals, rebounding and blocking shots,” but that relationship is by no means infallible. Ball throwing requires mechanical movements, the result of repetition and training. Things changed if we talked about aspects of the same sport that require other skills, such as “care.” Goodbye muses, hello pissed off. A good dose of rage can not only have its advantages on the court. Robson quote another study which suggest that anger can improve our “persistence and perseverance in the face of cognitive challenges.” How did they come to that conclusion? Scientists frustrated a group of people by giving them tests that in theory tested their intelligence but were actually impossible … Read more
