It turns out that there is an island in Fiji made of shellfish shells. Some crabs discovered it

Off the northern coast of Vanua Levu, the second largest island in the entire archipelago of Fijithere is a small island of 3,000 square meters. In a country made up of more than 300 islands scattered in the Pacific, the fact that there is one so small is not a surprise. But when you remove the mangroves and sand, what you have are shells. More specifically, edible seafood remains. The million dollar question now science is done It is whether that huge amount of shells is the work of people or nature. Once upon a time there was an island made of seafood remains. The shell deposit reaches 60 centimeters thick above the average high tide level and is between 20 and 40 centimeters thick on average and its composition is between 70% and 90% edible shellfish remains. Radiocarbon dating indicates that the greatest accumulation occurred around 760 AD, with samples spanning from approximately 420 to 1040 AD. That there is such an abundance of edible species gives a clue to the origin of the island: if it were a natural deposit, what would be expected would be to find an indiscriminate mixture of marine detritus, such as stones or inedible organisms from the seabed. Why is it important. Because everything indicates that this simple and small island is a “shell midden“, a “conchero” or shell dump created by humans. Or what is the same: the physical proof that there was once a community that lived, worked and fed in the area on the coast of Culasawani. Over the centuries, this accumulation of remains became an island demonstrating that even without wanting to, humans can make land without trying. On the other hand, historically there are not many archaeological studies in Vanua Levu and this site It constitutes a great opportunity to reconstruct ancient settlements and their customs. Context. The first time the research team was aware of the island was in 2017, in a general reconnaissance. It was the activity of the burrowing crabs that caught the team’s attention: the crustaceans brought material up to half a meter deep to the surface. In 2024 they resumed the investigation and they confirmed it: It was an island separated from the mainland. The “concheros” are an old acquaintance in the archeology of the Pacific, since they give many clues about how ancient communities lived, what they fed on and how they interacted with the environment. Of course, in this case the shell hole is so large that it has formed an entire island. The mangrove would arrive later, when the settlement had already been abandoned: the relative drop in sea level and the deforestation of inland areas released large quantities of sediment that functioned as a substrate on which to take root. In detail. To analyze it, the research team extracted 20 sediment cores and excavated four pits measuring one meter by one meter. All the remains of shellfish found in the sediments belonged to edible species, more specifically, the majority of the shellfish that make up them are clams of the genus Anadarain addition to other edible bivalves and gastropods and some ceramic fragments typical of human activity. The team found no clear evidence of animal bones, fish remains or stone tools, suggesting that these people gathered the shellfish in shallow waters, extracted the meat there and transported the food in ceramic vessels to another site, leaving the shells behind. Yes, but. In archeology, having the absolute truth is a chimera, but the most solid hypothesis with the evidence found is that it is an island of random human construction. The natural alternative involves a large wave or tsunami, but it is ruled out: it would carry away all types of marine organisms, not just those that are eaten. There is still one pending issue: where exactly the people who processed that seafood in the place lived. The team’s next step is to explore the mainland area near Culasawani to find the associated village and better understand how the entire system worked. And they are racing against the clock: what barely peeks through the mangroves is tremendously vulnerable to rising sea levels, a threat about which the Intergovernmental Panel on Climate Change has already warned.

“When someone who is 91 years old still remembers, you know it’s something special”

On August 12, the first of the solar eclipses that will make up the so-called Iberian Trio will take place. In 2026, 2027 and 2028 we will have solar eclipses that can be seen in Spain. The third will be annular, but the other two are total eclipses and their strip of totality crosses very different places. In 2026this strip goes from the north of Galicia to almost all of the Balearic Islands, passing through Asturias, Cantabria, La Rioja, the north of Castilla y León and the Valencian Community and a part of the Basque Country, Navarra, Madrid, Aragon, Catalonia and Castilla la Mancha. That of 2027, on the other hand, will be seen far to the south, especially in the area of ​​the Strait of Gibraltar. Something curious about the first eclipse is that it is expected to transport a large number of tourists to towns in what is known as emptied Spain. That is, to places that are not normally among the favorite destinations of national tourism. And much less from the international one. There are many people who have decided to organize their vacations this year around this astronomical event. August 12 has been marked on your calendar for many months. In some cases, even more than a year. After all, for astronomy lovers, having a total solar eclipse in your country is almost like having your favorite international singer come on tour in your city. I have talked about all this with Mabel Anguloone of those people who have decided to organize their vacations around the eclipse. Chatting with her it is inevitable to become infected with that illusion of seeing with your own eyes one of those shows that you can barely see once or a few times in your life. And, in reality, listening to it you understand that, two months before the big day, there are already so many hotels and rural accommodations full to the brim. What leads a person to organize their vacation around a solar eclipse? Mabel is a great lover of astronomy. In her work as a journalist for Canal Sur specialized in science, she especially enjoys communicating news that is related to space. Furthermore, years ago he became interested in astrophotography, a hobby that has helped him meet many other people with the same passion. Therefore, the opportunity to see a solar eclipse seems like a unique gift worth taking advantage of. “As an astronomy fan, I think it is one of the most amazing events you can witness.” Many of his colleagues have already seen one and only tell him wonderful things. “Everyone tells you that it is wonderful to see how day turns into night, to be able to see the crown, which is normally hidden from our sight… I am very curious.” Above all, he wants to see it with his own eyesto see if everything is as wonderful as they say. “Although I think so, because I see broadcasts from other places like the United States in 2024 and, honestly, those faces cannot be faked.” Plus, there is another very special reason why you want to see the eclipse. And he would like to be able to share with his mother the impressions of having witnessed one of these phenomena. “My mother saw the one from 1959. It is usually said that the one in 1912 was the last total solar eclipse in Spain, but no, gentlemen, it was the last one on the peninsula, in the Canary Islands there was one in ’59.” He had never told him this, but when she told him that she was planning her vacation to see this year’s one, he explained how she saw it then. “When a 91-year-old person keeps remembering that it was night and that it was incredible, you already know that it really is something special, that it will be part of the wonderful experiences of the life.” The only summer vacation For Mabel, this is going to be her only vacation. Although he also plans trips to see his family, the only leisure trip he will have this summer will be the one he has planned to see the eclipse. In your case, it will go to an area between Valladolid and Palencia. You have opted for a trip organized by a company called take me to the stars. Meet Heike Mai, CEO of the company, from the Jerez astronomy association. They told him that they were organizing trips and asked him about availability and prices. It was almost a year away, but there was only one gap left. Seeing that it was a “very good offer” he could not reject it. The accommodations were in double rooms, so he only had to find a companion. It didn’t take long for her to find it when she saw that a colleague from her astrophotography association was as excited as she was. The two friends will travel from Almería, where they live, to Valladolid by car. They will be in a rural accommodation for 5 days, during which they will take the opportunity to visit the surroundings and, of course, take many photographs. Of course, at the time of the eclipse Mabel’s plan is to enjoy, not obsess over the photos. “I’m going to live it,” he tells me. “I’ll set up the telescope and a camera and leave it on during the eclipse. If it comes out, great, if not, great.” Advance notice is essential Mabel began looking for ways to organize her vacation in September 2025, exploring possible offers and travel companions. Nevertheless, He left everything closed in January 2026. “In January we closed with Heike and she confirmed us in February,” he recalls. “She wanted us to close everything in time, especially for fear of the prices going up, because it already happened to her with an accommodation that they canceled it and then she saw it uploaded to another, much more expensive portal.” This is something that is … Read more

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

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

Jeff Bezos says AI won’t destroy jobs. He then launched a company to create artificial engineers

Jeff Bezos is one of the representative figures of current technological optimism regarding artificial intelligence. While in the United States we are seeing the university students who boo to those who claim that AI is the new industrial revolution due to pessimism when it comes to finding a job, Bezos point that this pessimism around AI is “the opposite of reality.” Come on, young people are wrong because what AI is going to do is create jobs. At the same time, Bezos has returned to talk of Prometheusa startup that will open the door to fewer workers being needed… while increasing productivity. It’s a bit of a mess, but it makes sense to Bezos. Prometheus. It is not a model or a technology, but a startup. Founded by Bezos in 2024, it has about 150 employees spread across headquarters in San Francisco, London and Zurich and already has a valuation of $41 billion. The central purpose of Prometheus is to develop AI systems capable of assisting in the entire engineering process from start to finish (end to end, as they call it). This means that the system will cover from the initial design of physical products to their manufacturing and launch, passing through all the simulation and testing phases. It is like a kind of artificial general engineer and does not seek to be just something that supports the engineers, who will then create the physical products. His goal is… that, to be a physical engineer. Accelerate inventions. Beszos’ goal is to empower engineers to be able to invent things more quickly and easily. An example is that this AI product is capable of carrying out all the aforementioned steps to build, for example, a jet engine. And here is the twist, since a jet engine is something extremely complex, but what Bezos is looking for is that what the startup develops allows smaller teams to do much bigger things in much shorter cycle times. Landing it: if before 100 people made you a new generation jet engine, now 10 can make it for you. I don’t know, Rick.… We suppose that in his head it is a good way to reassure those young people worried about the future of work, but in case it is not clear, Bezos commented that the fear of AI and the future of work is “the opposite of reality”, pointing out that what Prometheus does will be a catalyst for work. The curious thing is that he has presented it in a slightly strange way. If AI makes work cheaper, faster and easier, employment will increase because, “even though the number of people needed is being reduced by 10, technology will create opportunities to multiply those jobs by 10.” They are a bit strange accounts, but the boss of Amazon gives as an example a two-person household in which only one will have to work because productivity thanks to AI will be much greater. It does not say what that other person will do or if, thanks to AI, that member of the household who continues to work will earn more to replace one who stays at home. What it suggests is that there will be such a massive increase in productivity that not everyone will have to work, a somewhat questionable message because bills are not paid with productivity, but with money. colossal background. But well, beyond Bezos’ curious message, Prometheus is valued at $41 billion and has raised $12 billion from investors such as JPMorgan Chase, Goldman Sachs and BlackRock, apart from Bezos himself. And, currently, it is in deals to raise a fund of 100,000 million. But Bezos isn’t the only one moving to build AI startups. We have the founders of Uber, Coinbase or Robinhood (curious name) building new companies around this technology boom due to something that these profiles are very clear about: It is a new golden era and the best way to start a company. Young Americans are not so clear. In Xataka | Jensen Huang, CEO of Nvidia, on the possibility that we are facing a work apocalypse: “It’s nonsense”

I thought that in 2026 I could buy a cheap cell phone without worrying about anything. big mistake

I have spent half my life being especially critical when analyzing phones and, on the only occasion that I have decided to stop being so, I have hit a wall. We are in 2026, a year in which one might think that at this point in the game practically any phone newly launched on the market must work well. Mistake, big mistake. So I want to tell you how the component crisis in the technology sector and, to be honest, a certain apathy on the part of manufacturers, continues to make choosing an affordable mobile phone complex in 2026. Either we look closely at what we buy, or it may turn out to be a failure. The objectives. A mobile to send and receive WhatsAppsliterally. I wanted a phone whose main use was to manage communication with clients in one of my projects and, taking advantage of the fact that I had a new purchase, use it as GPS when I ride a motorcycle. The demands were minimal, there were practically no requirements other than that the cell phone worked decently. The expectation was not high either: I know that a low-end mobile phone does not work like a high-end one, not even like a mid-range one. I was just looking for something functional and simple. The search. I started the search, with phones over 100 euros. For that price it was practically impossible to access basic phones like the LITTLE M7which at least has a Snapdragon 685 (a processor, mind you, from 2023), so I had to continue lowering the bar. I ended up finding a 199 euro phone on sale for 89 euros on Aliexpress. One with 8 GB of RAM, 256 GB of internal memory… and a Helium G100 Ultra. the drama. The Helio G100 Ultra is an entry-level processor launched in 2024, relatively modern, and should have enough capacity to run basic applications. That’s what I thought. It’s been a while since I’ve tried an entry-level model. I thought that in 2026 things would be a little better, and I couldn’t be more wrong Almost two seconds to open the camera, lag in the launcher with the mobile newly configured, constant freezes and a performance that, after having tried other cheap mobile phones of a similar price (without offer), was simply unacceptable. And no, I’m not going to tell you the model so as not to draw blood, but it is one of the most popular mobile phones in Spain. Blind. One of the supposed advantages that it has brought us the semiconductor race is all about performance. For some time now, in certain ranges, my recommendations when asked which mobile phone to buy for The same does not happen with the entry ranges. Processors like Helium G99Helio G100, and even some Snapdragon 600 series (or Gen 6) are still barely moving basic apps. And the worrying thing is not how the phone performs right out of the box (which already performs poorly), it is how it will perform in a few years with some hardware degradation, system and app updates. big horse. At this point in the game there is something that is very clear to me, something that I have always defended: the processor It is much more important than we can think as average users. It is the heart of our mobile: The Gross Performance Manager The person in charge of the modem who will make us have better or worse coverage The element behind photo quality and camera performance The one that allows the final audio quality to be better or worse The one that helps to manage energy consumption more or less efficiently And here, even though the chip race continues at its pace, the high-end processors from a few years ago are noticeably superior to the entry-level ones. So between that high end of 2024 full of chicha and that newly released entry range… I’m clear about what I should have done. Image | Xataka In Xataka | Best mobile phones in quality price.

Few watches are designed by and for padel players. This is one of them, and I have tried it

What will we have to do as padel players so that smart watches do not allow us to monitor our matches. That same question I did it to myself back in 2021, five years ago, and the film is not very different from today. Although paddle tennis is an extremely popular sport, few, almost none, are the brands that remember those of us who enjoy this sport, and those that do remember have paddle modes that do not provide any useful information. Then MWC arrived and there I discovered Mibroa Chinese brand of smart watches that seeks to differentiate itself right there, in paddle tennis. They openly acknowledged that it is not that padel is gaining popularity in China, but that they want to use this sport to enter Europe. And of course, as someone who has been playing paddle tennis since I was little, I was curious, so I decided to try one of their watches on my own wrist. During these last weeks I have been using the Mibro GS Pro2 during my matches and padel classes, and this has been my experience. Forehand, backhand, layup, small to the foot Mibro GS Pro2 | Image: Xataka As a smartwatch, the Mibro GS 2 Pro ticks almost every box. It’s big, but comfortable; The screen looks good, the battery lasts two weeks with complete peace of mind and allows you to receive notifications, calls, etc. It has, however, three problems: The operating system, which is an RTOS, moves somewhat lazily and responds a little slowly to touches and gestures. You have a connectivity problem with your mobile phone that causes notifications to stop coming in at specific times. It lacks advanced functions such as ECG or mobile payments, something that cannot be criticized since it costs 140 euros. It has serious translation problems into Spanish, both in the app and on the watch. Positive part? The problem of performance, connectivity and the app could be fixed with a software updateit’s not something that worries me at all. Be that as it may, we have come here to talk about paddle tennis, so let’s get down to business. When we enter the court and activate the paddle mode, the first thing we have to do is put the watch on the same wrist as the hand with which we hold the paddle. I always wear the watch on my left wrist, but since I am right-handed, I hold the paddle with my right. This has no relevance in tennis, since the racket has no wrist ties, but in padel it is different. A paddle tennis racket has a wrist support that prevents it from flying away if our hand gets sweaty, if it slips due to a strong blow, etc. That support goes to the wrist, right where we have the watch. If it’s just a little rope, nothing happens, but if the grip is larger, as is my case, it can be a little uncomfortable. This, however, will depend on each person’s shovel. During the session, the watch measures in real time the type of stroke and the speed with which we execute it. You can actually see it live as you play. This is quite useful, especially when the hit defines the point. It helps you know if, perhaps, you have come forward with force in a defensive blow. This information, well managed, is useful, and you are going to allow me to go into coffee mode for coffee lovers. Mibro GS Pro2 | Image: Xataka Although paddle tennis seems like a sport where you hit the ball very hard, the truth is that it is not like that at all. As a general rule, a looser, well-defined stroke is more useful What a very strong blow. The weak and well-placed blow, hitting the wall or the mesh, creates more difficulty for the opponent. The strong hit, however, usually gives more opportunities. It all depends on the case, needless to say, but if you watch a professional padel game you will realize that they only hit the ball when they know very well that they are going to hit it for four (over the rear glass), for three (through the side glass) or that they are going to bring it back (the ball hits the opposite glass and returns to our court). And in fact, there is no need to spank him because, again, it is more a question of technique than strength. For the rest, they tend to use “weaker” and intentional blows. Mibro GS Pro2 | Image: Xataka And why am I telling you this? Because I, who go to weekly classes, have found it very useful review the speed applied to the blows to discover what I do well and what I do wrong. If I am volleying on the backhand and I want the ball to go to the cross net or deep to the double wall, a strong hit is of little use to me. Better a weak one. Reviewing the speed at which I hit the shot when it went well (or badly) helps me adjust future shots and memorize gestures. Coupled with the teacher’s feedback regarding posture, position and rhythm, it is valuable information. The watch detects the type of blow and its direction quite accurately. In the screenshots above you can see on the left a paddle tennis class focused on layups alternating turns of forehand and backhand; and on the right a game (which we lost, unfortunately) in which I played backhand, ergo the proportion of forehand shots is higher, the proportion of layups is too low and the proportion of lobs is too high. What does that mean? They took us out of the net very easily, they always kept us at the back and, therefore, we had little attacking capacity. The lack of context This information is useful, but if you know how to play you will know, with complete certainty, why you have won or … Read more

the two pharaonic African gas pipelines that want to change the energy map

The invasion of Ukraine in 2022 dynamited the foundations of European energy security. Before the conflict, Russia supplied between 40% and 45% of the European Union’s natural gas imports, injecting more than 155 billion cubic meters annually into the continent. Faced with the urgency of disconnecting from Moscow, Europe was looking for a place to fill its reserves again and the answer was in the south. To understand the magnitude of this shift, just look at what is happening on the ground. According to The Africa Reportunder the scorching sun of southern Algeria, the energy ministers of Algeria, Nigeria and Niger officially inaugurated the works of the gigantic Trans-Saharan Gas Pipeline (TSGP). It is not a project on paper; the pipes are already being welded. As detailed Al-Monitorthe Algerian state company Sonatrach has begun building a critical 1,210 kilometer stretch in the Aoulef region, which will connect Nigerian gas to the immense Hassi R’Mel field, a node that already has direct arteries to Europe. A question of survival. The European Union plans to end its dependence on Russian gas at the end of 2027. The arrival of a new corridor that provides 30 billion cubic meters of gas per year is a strategic lifeline. But for the African continent, the meaning is even deeper. It is about resolving a historical paradox: being a continent rich in energy but with serious deficiencies in local electricity access. According to an investigation published in the Journal of Geo-Energy and Environmentthe rival project, the Africa-Atlantic Gas Pipeline (AAGP), could generate about $75 million annually in transit revenue for West African countries. Furthermore, these projects are designed so that a part of the gas stays in the transit countries, promoting their electrification, their industrial development and reducing the use of polluting biomass. The battle of the megaprojects. However, this energy awakening has unleashed a fierce geopolitical rivalry. As highlighted The Africa ReportAlgeria and Morocco are competing aggressively to become the exclusive “gateway” for Nigerian gas to Europe, spearheading two colossal megaprojects competing for international funding and European favor. On the table are two titans of engineering that promise to change the world map: The Trans-Saharan Gas Pipeline (TSGP): Led by Nigeria, Niger and Algeria. Business Insider details that it will measure 4,128 kilometers in length. It will cross the desert and it is estimated that its cost ranges between 13,000 million dollars and the 19.5 billion. With the works already started in Algeria, the Minister of Petroleum of Niger has confirmed that his country will begin to build its section of 720 kilometers at the beginning of 2027. The Africa-Atlantic Gas Pipeline (AAGP / NMGP): The Moroccan alternative is even more pharaonic. With a length of between 5,600 and 7,000 kilometers, it will border the entire Atlantic coast, crossing 13 African countries. Its estimated cost amounts to about 25 billion dollars. How to finance infrastructure of this magnitude? academic research concludes thatAfter analyzing multiple strategies, the Public-Private Partnership (PPP) model is the most robust and viable path. This model makes it possible to mobilize the gigantic private capital necessary, transfer the risks of construction and operation, and at the same time ensure that local governments maintain fiscal benefits and employment development. The small print. Despite the euphoria, the obstacles are formidable. As you remember Al-Monitorthe trans-Saharan gas pipeline was conceived in the 1970s and has suffered decades of paralysis. Academic analyzes warn that the viability of the project is threatened by historical security risks in the Niger Delta, northern Niger and southern Algeria, coupled with political instability caused by recent coups in the Sahel region. Furthermore, there is an “elephant in the room”: the energy transition. Natural gas is seen as a transition fuel. So that these gas pipelines do not become stranded (obsolete) assets in the long term in the face of European climate policies, experts point out that they must be designed with operational flexibility. This includes “reverse flow” capability to redistribute energy southwards when Europe doesn’t need it, and even adapt infrastructure to transport green hydrogen in a decarbonized future. A new axis of power. The center of gravity of world energy is falling southward. Europe, cornered by geopolitics, desperately needs the stability of new suppliers; Africa, for its part, demands the investment and infrastructure it has historically been denied. The success of these thousands of kilometers of steel tubes, buried under the burning sands of the Sahara or submerged off the Atlantic coast, will decide much more than the temperature of European homes in the coming winters. The true historical challenge is not to demonstrate that the continent can turn on the northern lights, but to dare to invent a model where Africa stops exporting its wealth to import dependence. The ultimate goal is for African energy to belong to and transform, once and for all, its own people.

is to eat three meals every day

The pattern we follow today of breakfast, lunch and dinner is so ingrained in our daily routine that we tend to assume it as a human physiological need. However, neither evolutionary biology nor clinical nutrition dictates a universal rule about how many times you should eat per day, since the idea that “three meals a day” is a norm dictated by nature clashes with reality, since History shows us how it has been a habit that has been shaped over the years. A history class. For centuries, in places like England and the United Statess, a large part of the population only ate two main meals a day, but the three-course scheme became established when salaried work, factories and school schedules made a regular distribution of the day more useful. And although we tend to think that we always ate this way, eating patterns are reordered with the new urban and work schedules driven by the Industrial Revolution. A turning point. The consolidation of breakfast, lunch and dinner went hand in hand with the industrialization and urbanization of society, although it did not occur identically or simultaneously in all countries. In fact, in the European fieldthe main meal used to be strongly linked to midday, so the evening “dinner”, understood as the big family meal, is much later than common sense suggests. Therefore, when it comes to being rigorous, it is not appropriate to affirm without nuances that the Industrial Revolution “invented” the three meals from one day to the next, because history shows us that the evolution was more gradual and strongly depended on the country and social class. a study published in the magazine Annals of Nutrition and Metabolism point that European dietary patterns changed due to these economic and social transformations. But what is clear is that the modern pattern was consolidated with industrialization, urbanization and the arrival of more rigid work schedules that structured people’s lives. What does physiology say? Beyond the historical evolution that we have had as a society, medical science indicates that there is no strong base to say that a fixed number of meals is a universal biological law. Delving deeper into the evidence we have, a review published in the journal Nutrients in 2022 determined that what we know about meal frequency is limited and heterogeneous, concluding that there is no universal rule valid for everyone. What we have seen with different trials is that reducing the frequency of meals, even without applying caloric restriction, can alter some metabolic markers, but this does not at all demonstrate a universal superiority of a specific number of times to eat. Likewise, the well-known population study EPIC-Norfolk found a link between how often we eat and serum cholesterol levels, a reminder that “eating more” does not automatically equate to “better health.” How we distribute the food. A meta-analysis published in JAMA indicates that the timing and distribution of meals can influence weight and metabolism, but that is not the same as defending a specific frequency as the norm for everyone. What nutritional chronobiology does warn us about is that the internal clock plays a crucial role and consuming food in the morning is associated with a better metabolic profile in some studies, while eating at night or irregularly is related to worse results. This is why maintaining irregular eating habits during adolescence can even be associated with poorer long-term cardiometabolic health in adulthood.

We believed that a master’s degree was a guarantee of finding a job. It’s starting to be of exactly no use.

When you have higher education and can’t find a job or want to advance, historically a good idea has always been to go back to school. Getting a master’s degree was an almost safe investment in the face of uncertainty because it allowed you to specialize and find a better job. However, if we talk about master’s degrees, that reality is no longer true. More specifically, general master’s degrees. Because while doctorates or qualifying master’s degrees do work, general master’s degrees suffer an alarming devaluation in the market: according to a study by the Burning Glass Institute with data from the Bureau of Employment Statistics (BLS) of which echoesThe Wall Street Journalthe unemployment rate in the United States among those under 35 years of age with a master’s degree is at one of its highest levels in the last 20 years. Master’s degrees are worth less and less. What the Burning Glass analysis says is that those who have a master’s degree under 35 years of age are in the 77th percentile of unemployment when the normal is the 50th percentile. In fact, they are behind those with less education. Of course, we are talking about general master’s degrees, not qualifying ones. Furthermore, this phenomenon does not occur among those who have a doctorate. Gad Levanon, chief economist at the Burning Glass Institute, sums it up appealing to the law of supply and demand: “there are more titles competing for fewer positions than those titles were designed to unlock.” In short: once a master’s degree was a sign of distinction, but when everyone has it, it no longer makes a difference. Why is it important. Beyond statistical curiosity, it is a question of time, money and expectations. Making an effort to pay for a master’s degree thinking that it is an investment with a quick return and when it is not is frustrating. Plus, a 2025 Indeed survey collect that more than a third of graduates consider that their university degree was a waste of money or time and that they could do the same without it. In the case of generation Z, the percentage rises to 51%. The boom in master’s degrees has also reached human resources departments: the Society for Human Resource Management warns that more and more companies are replacing degree requirements with practical skills criteria. This represents a gap between young people who accumulate theoretical degrees and human resources offices, which are looking for talent prioritizing, not the paper that proves that you studied it. Context. The market for people with a master’s degree is saturated simply because there are too many master’s degrees: hyper-specific, online and blended, express… because non-qualifying higher education is a most lucrative business. In the United States between 2005 and 2021, the master’s degree offer grew by 69% to exceed 33,500 according to the Postsecondary Education and Economics Research Center. In Spain, more of the same: “The Spanish university in figures” collect that the offer of master’s degrees in Spain has skyrocketed by 54% since the implementation of the Bologna Plan, going from 2,626 to more than 4,000 official degrees. This boom has been driven exponentially by private universities, with enrollment growth of 250% more. Meanwhile, two things happened that helped this perfect storm: according to Lightcast data analyzed by the Wall Street Journal, the percentage of job offers that require a university degree fell to 17.8% in 2024 compared to 20.4% five years ago, a trend that already affects 87% of sectors. The second big problem of young graduates is called AI: while HR looks for decisive people, companies are betting on artificial intelligence for those junior positions essential to gain experience. In Spain they work, but with small print. The CYD 2024 report points out that in 2023 Spain reached the highest overqualification rate in the entire European Union: 35.8% of higher graduates between 20 and 64 years old work in low-skilled positions, compared to the 21.9% average in the EU. That is to say, it is not that these master’s degrees do not help you find a job, it is that they help you find a job below what they promise. Yes, but. Practical skills may be emerging as an important requirement for employability, but theory is one thing and practice another: although 85% of companies say they hire based on skills, when it comes down to it, only 1 in every 700 actual hires meets that criterion. according to a report joint Burning Glass Institute and Harvard Business School. On the other hand, there are master’s degrees and master’s degrees: we have already seen that the qualifications continue to work and there are also subjects with high demand that make them potentially attractive.
