If you’re wondering where all those shared scooters went, this study gives you the answer

You probably remember it if you have lived in a Spanish city in the last ten years. Overnight, your city was filled with electric scooters and shared bikes. Everywhere. Everywhere. Some well parked, others that made you feel like a 3,000 meter steeplechase athlete. As the last decade nears its end, Spain joined the wave of shared micromobility. Our streets were filled with operators who put on the streets, under the pay-per-use formula, electric scooters, bicycles and cars that promised to revolutionize the way we move. The formula coincided with another movement: low emission zones. At the end of 2018, Madrid launched Madrid Central. With this project he intended to reduce the volume of cars on the street in its central almond. In 2019, Barcelona began to apply similar measures in a much larger area, in this case it extended to the entire metropolitan area of ​​the city. The general feeling is that we were facing a model that had come to stay. The message was that the volume of cars in city centers had to be reduced and that young people, increasingly less interested in their own car, would combine public transport with scooters and electric bicycles for shared use. A new, more efficient door-to-door mobility. Today, almost nothing remains of that. The new and shared mobility that disappeared To understand what happened with that movement, Andrés Camacho Donezar, Professor of Business Strategy and business models, Universidad Pontificia Comillas, and Carmen Valor Martínez, teacher and researcher at the Faculty of Economics and Business Sciences (ICADE), Department of Marketing, Universidad Pontificia Comillas, have carried out a study in which the evolution of 10 operators that were or are part of micromobility services in our country has been studied. The conclusions have presented them in The Conversation which explains the problems that these companies had to face and how what seemed like a perfect business, with clear benefits for citizens, ended up being diluted over the years. The study indicates that shared micromobility has three obvious benefits: it is affordable for the vast majority of citizens, it is good for society as a whole because it facilitates access to mobility for all types of incomes and, in addition, it is environmentally beneficial since it should reduce traffic and polluting emissions. These promises laid a rug for all types of companies put their vehicles on the street. The most paradigmatic case was that of Madrid, which had up to 18 companies fighting for users and a regulation that allowed having on the street up to 10,000 electric scooters. After various regulatory attempts and closing the concession to three companies, in 2024 it ended up banning them completely. The process was similar to that of Barcelona, Saragossa either Sevilleto give a few examples. In all these cities, the private companies They tried to do business by attracting new users, the neighbors were divided between those who enjoyed them and those who suffered from them. Until, finally, the City Councils ended up banning them. The reasons have almost always been the same. The study details the problems that operators have had to make the service profitable. From an expansive phase to cover the maximum possible territory, we have moved on to atomization, closing the circle. Vandalism, high collection costs and repairs they began to complicate the business from a purely commercial point of view. To this we must add the neighborhood complaints that led to greater pressure from the City Councils towards the companies. Already in 2018, articles began to proliferate that echoed a problem: the streets were invaded by shared electric scooters. Due to a lack of civility and clearly insufficient control by companies, pedestrians began to encounter new obstacles. After many complaints, also in European cities with Paris in the leadthe City Councils began to put their restrictions. In Madrid, for example, it happened from “door to door” to virtual stations. Users could only pick up or park an electric scooter in limited and geolocated spaces. It was a mortal wound for a service that promised to save the last mile. To this we must add that these same town councils saw another business opportunity: controlling micromobility services themselves. And in most of the large Spanish cities public bicycle sharing services have been launched. With limited spaces to collect and release bicycles and a maintenance service that is not pressured by extraordinarily narrow profit margins. The result is that these shared electric scooter companies, the few that remain, have mostly pivoted to offer themselves as a solution to tour operators that offer rides or tourist visits using this means of transport or supply vehicles to the town councils themselves, like Lime in Getafe (Madrid). With mandatory restrictions (geolocation systems, limited parking spaces…) and some citizens who have rejected the use of electric scooters, shared mobility with these vehicles It has been impossible to make profitable. And public bikes have killed the possibility of the business pivoting to this vehicle. The result is a micromobility service that seemed perfect on paper but failed in practice.

You bought an electric car to save. Here’s why you’re not doing it

It’s 7:30 p.m. You get home, put away your coat, plug in the car and forget about it. You’ve done it like this every day since you bought the electric one. Until the electricity bill arrives and nothing adds up. The car doesn’t consume gasoline, yes, but something has gone wrong. That something has a name: you’ve been paying the most expensive electricity of the day to charge a battery that could have been filled for half the price while you were sleeping. It’s 7:30 p.m. You get home, put away your coat, plug in the car and forget about it. You’ve done it like this every day since you bought the electric one. Until the electricity bill arrives and nothing adds up. The car doesn’t consume gasoline, yes, but something has gone wrong. That something has a name: you’ve been paying the most expensive electricity of the day to charge a battery that could have been filled for half the price while you were sleeping. The 280 kWh error. Think of any family: apartment, refrigerator, washing machine, some heating. About 290 kWh per month. The day they park an electric car in the garage and start charging it at home, those 290 kWh become 570. The car adds about 280 kWh per month on its own, counting what is lost in the charging itself. If they plug it in in the middle of the afternoon, they are paying for that mass of energy at the most expensive price of the day. The same amount of kWh can cost twice as much depending only on the time at which it is consumed. The key is no longer just how much is consumed, but when it is consumed. The three traps. The first instinct when buying an electric car is to call the company and ask for more contracted power, for fear that the leads will trip if the car is connected with the washing machine running. Alejandro Diego Rosell, energy consultant and professoridentifies it as one of the most common and most expensive mistakes: oversizing the power means paying an unnecessary safety margin every month, even if you never use it. But the thing doesn’t stop there. Many users believe that the regulated market (PVPC) is the safest haven. According to Sergio Soto’s calculations, energy expert Roamsa model household with an electric car would pay about 101.67 euros per month in PVPC, penalized by hourly volatility and increases in prices in certain sections. Cheap when the price drops, yes. But unpredictable when it rises, and rises just when it is most consumed. And there remains the one that is most abundant in advertising and the one that deceives the most: EV rates. Rosell sums it up with a rule that should not be forgotten: “You are still saving 8 euros by charging the car and losing 15 in the rest of the house.” You have to look at the nightly price, but also what they charge during normal hours and what is in the fine print of the fixed term. Some EV rates offer a very cheap early morning to recover the margin the rest of the day. The name does not guarantee anything. The roadmap. For the electric car to be truly profitable, experts propose following these steps: Apply the exact power formula: Rosell proposes a simple account: Necessary power = simultaneous consumption of the house + charger power + safety margin. If at dawn you have a refrigerator, water heater and air heater consuming 1.5 kW and you charge the car at 3.7 kW, you need about 5.2 kW in total. With a safety margin, you would hire 5.75 kW, not 10. And there is a nuance that changes everything: a smart charger can automatically reduce the car’s power if it detects that the house is consuming more. The car waits. The leads don’t jump. Play two powers: Current legislation (2.0TD rates) allows contracting a lower power for the day and a higher power only for the night (valley). This way you don’t pay all day for a power that you only use while you sleep. Escape from commercial trends: Faced with the avalanche of so-called ‘EV Rates’ (specific for electric vehicles), Soto warns that the most economical option is usually a well-optimized classic rate with three-period time discrimination (DH3). In a practical case, this rate would lower the bill to 74.90 euros per month, representing a saving of 26.3% compared to the regulated market. EV rates are still competitive (about 77.50 euros), but they can be slightly more expensive than a good DH3. To compare without trusting advertising: the official comparator of the CNMC and the hourly prices of the PVPC published by Red Eléctrica in ESIOS are the reference tools. Install a smart charger. A conventional plug is slow and offers no control. A wallbox allows you to program the load so that it starts on its own during the cheapest hours and adjusts the energy so as not to exceed the contracted power. Rosell places the cost of the equipment between 400 and 800 euros; Soto, adding the complete installation, between 600 and 1,500 euros depending on the case. Important: the wallbox does not pay for itself only by the kWh saved, but also by the control, security and comfort it provides. And the investment is significantly cut with the Auto+ Plan, which subsidizes up to 70% of the installation for individuals and up to 80% in municipalities with less than 5,000 inhabitants. What if we collapse the network? With an increase in plug-in vehicle registrations which exceeds 44%it is legitimate to wonder if there will be blackouts when we all charge at dawn. Soto calls for calm: the problem is not that everyone charges at night, but that everyone does it at the same time and at high powers. With smart charging and distributed management, the grid holds up. Rosell adds something more important for the long term: the “eternal cheap night” is … Read more

If he wants to beat Anthropic, he needs more hands. So you’re going to double your template.

OpenAI just realized that they had been launching products without rhyme or reason and they need to focus on something. And that something is the business sector, where an Anthropic with a much clearer business plan has been eating up their ground. To achieve this they need to increase their staff. A lot. More hands. According to Financial TimesOpenAI is planning to increase its staff throughout the year, almost doubling it. They currently have around 4,500 workers and the idea, according to internal sources, is to reach 8,000. To reach that figure they would have to hire 12 people a day; human resources will be on fire. The departments that need the most personnel are product development, engineering, research and sales. In addition, there is a figure that the company wants to reinforce; These are “technical ambassadors”, who will be a type of advisors who will guide companies that use their products so that they get the most out of them. They have also rented new offices in San Francisco, which will bring the total surface area to more than 90,000 square meters. Unstoppable Anthropic. This is part of a strategic reform that seeks to regain ground in the business segment, where Anthropic has gained a very solid position. According to data from Ramp AI IndexAlthough OpenAI is still the most used solution in business, adoption is falling while Anthropic is doing like a shot. 70% of companies that buy AI solutions for the first time choose Anthropic, at this rate, in a short time they will overtake them in the number of business users. It’s not that big of a deal. OpenAI has downplayed this figure because Ramp is a financial service and its data comes only from transactions made with your credit card “it’s like saying that global sales of lemons can be calculated based on my son’s lemonade stand,” said a company spokesperson. Be that as it may, the reality is that OpenAI is taking steps towards a restructuring of its product portfolio and its organization, and recovering business share is among its priorities. Unify portfolio. As part of this strategic pivot, OpenAI is planning the launch of a super app that will unify Codex, ChatGPT and the Atlas browser into a single tool. During 2025, OpenAI launched many very disparate products, many of them being half abandoned along the way like ChatGPT Atlas. In addition to showing a clear lack of focus, it is a very inefficient strategy; There are many computers, they all need computing capacity and no one is clear about what to prioritize, a disaster. The change is led by Fidji Simo, the company’s apps manager, who recently told employees “We cannot waste this moment because we are distracted by parallel projects.” The agreement with the Pentagon. All this coincides with the soap opera of Anthropic and the Pentagon. After weeks of tensions, Anthropic finally ended up on the government’s blacklist and OpenAI signed the agreement. What followed was that people started uninstalling ChatGPT en masse and in the public eye ChatGPT became the bad AI and Anthropic became the good AI that had not given in to government pressures. Sam Altman assured that there was no problemthat we could rest assured and that they also had red lines, a statement that has little to do with the facts.

Sam Altman says he’s terrified of a world where AI companies believe themselves to be more powerful than the government. It’s just what you’re building

Sam Altman sat down over the weekend before his audience at X to answer questions about the agreement that OpenAI has just signed with the United States War Department. What came out of that session was a beautiful involuntary x-ray of the biggest contradiction in the sector at the moment. Why is it important. The CEO of OpenAI said he is terrified of “a world where AI companies act as if they have more power than the government.” The phrase sounds good, it is marketinian and seeks to elevate OpenAI’s position as a powerful but very responsible and honest group. The problem is the context in which he pronounces it: hours before OpenAI signed that agreement, The US government labeled Anthropic, its direct rival, a “supply chain risk” for refusing to sign under those same conditions. Altman went to put out the fire just as someone accused him of setting it. Between the lines. Altman’s speech rests on a premise that must be monitored: that a democratically elected government must always prevail over unelected private companies. It is a philosophically reasonable position, but he applies it selectively. Altman acknowledged that the deal “was rushed and the picture is not good,” and that OpenAI moved quickly to “de-escalate” tension between the Pentagon and industry. In other words, your company made a unilateral strategic decision about how the entire AI industry should relate to the military establishment. That doesn’t exactly sound like institutional deference. The contrast. Anthropic opted for something different: requiring explicit safeguards against the use of its AI for mass surveillance or autonomous weapons. But the government penalized her. OpenAI accepted a more ambiguous formula (“for all legal uses”) and won the contract. Various OpenAI employees signed a letter supporting Anthropic’s position. Claude became the most downloaded free application in the App Store that weekend from Apple, precisely surpassing ChatGPT. The market also has opinions. Yes, but. It’s fair to admit that Altman’s position has some internal logic: If AI is going to be integrated into military systems anyway, it may be preferable that it do so under negotiated conditions rather than under coercion. And he’s right about one thing: The labeling of Anthropic as a supply chain risk, a tool intended for hostile foreign suppliers, applied to an American AI security company is, in his own words, “an extremely frightening precedent.” The big question. Who really decides how AI is used in military contexts? The companies that build it, the governments that hire it, or the engineers who design it and who are increasingly organized to influence those decisions? Altman says he believes in the democratic process. But OpenAI negotiated privately, signed privately, and made only a fraction of the contract public. Democratic transparency starts there.

If you’re in a hurry to upgrade your PC, NVIDIA’s CEO has bad news: don’t be in a hurry

Talking about artificial intelligence is talking about Jensen Huang. The CEO of NVIDIA has become the figure of an industry: that of artificial intelligence. In large part, it is your company’s products that are driving the engine of the data centers and, at the same time, enormous semiconductor industries and memory are the essential components of NVIDIA GPUs. And if Huang has been commenting for a few weeks that this 2026 it’s going to need wafers and a lot of RAMhas now asked for patience with AI. Because he has another seven or eight years of unchecked climbing left. In short. When we talk about artificial intelligence, there are two poles. On the one hand, those who see signs of a bubble that will burst in the short term. On the other hand, those who defend the billion-dollar investment against all odds. In that boat is Jensen Huang, who recently noted in CNBC that this massive spending is “necessary and appropriate” because a “once-in-a-generation infrastructure” is being shaped. The most interesting thing is that, for him, this career will continue for several years, pointing that the investment and construction of infrastructure for AI has seven or eight years left. Mortars of money. In his statements, Huang pointed out that companies like Anthropic and OpenAI are making money despite everything invested and that their current brake is not so much the budget as the limit of computing power. That is why you want your suppliers –Samsung in HBM4 memories new generation or TSMC with the processors- increase the pace. It remains to be seen, however, if the pace can be maintained over the next five years. On CNBC, the CEO of NVIDIA pointed out that, despite the astronomical amount of money, the spending is sustainable. And proof of this is that it is increasing. If in 2025 the total spending of Big Tech did not reach 400,000 million, wait that this year the number of American companies will rise to 650,000 million. Only between Amazon and Alphabet -Google-, they will invest about 385,000 million. They see the AI ​​computing race as the next “whoever wins the most,” and none are willing to lose – DA Davidson analyst Gil Luria speaking to Bloomberg Parallel career. And that, as we say, in American companies, since China is the other pole in this race for artificial intelligence. The Asian giant is the birthplace of several extremely capable models, but also something that is missing in the United States: energy to feed the enormous needs of AI. China is betting on AI, but also on robotics, and all this at the same time buy NVIDIA products and develop your own semiconductor network with the goal of achieving technological sovereignty. It is another race parallel to that of the United States, and apart from the two poles of infrastructure development, we have particular names. That so much money is being invested means that opportunities are being created, and there are companies that have gone through a bad patch and want to surf the wave. For example, a Intel that, after needing a rescue by the United Statesis positioning itself as one of the great foundries in the United States. In addition, they are putting their foot in a segment that they had not explored, that of DRAM memory, and They are doing it with the Japanese giant SoftBank. Japan has not had a say in the memory industry since the 80s, when South Korea snatched their positionand now they may have another chance. Translation for the user. These are a couple of examples of companies that are taking advantage of the conditions to obtain financing and expand, seeking to position themselves in what they have determined is the future of the technology industry. With that amount of money and investment, there is a question you may be asking yourself: will I be able to buy a PC? The answer It is not hopeful. Giants like Micron -one of the heavyweights in the RAM segment- They are investing a lot to expand facilities and be more capable when creating memories, but they will not be for us: they will be for data centers. If the end of 2026 or 2027 was targeted as the end of the component crisis like the RAM or SSD (which are still components with memory modules), now it is Lip-Bu TanCEO of Intel, who states that It won’t be until 2028at the earliest, when we can see a horizon in the current panorama. So, yes, the entire tech industry has turned to AI and those that can increase their production of key components will do so over the next few years. The issue is that they are going to focus on components that users neither care about nor care about, neglecting those that we really need on a day-to-day basis. AND an example is NVIDIA itself.

In China, glaciers have become a tourist attraction. So you’re protecting them from global warming with XL blankets

Located in the province of Sichuan, just 300 kilometers from Chengdu, the Dagu glacier offers such fabulous landscapes that every year it receives several hundred thousand tourists. They come from other parts of the country or the planet to enjoy the snow and the views from their cable car. For scientists, however, Dagu is more than just a white paradise. In his opinion it looks more like a “terminally ill”a patient they must care for to avoid (or at least delay) the fatal outcome: the slow and unstoppable loss of ice due to climate change. For this purpose, a group of Chinese researchers has had a curious idea, to say the least: ‘covering’ part of the glacier with a gigantic blanket. A threatened paradise. Dagu is more than a glacier the tibetan plateau full of landscapes instagrammable. It is also a fundamental piece in the region’s economy. The enormous mass of ice attracts more than 200,000 tourists per year, which keeps an industry that employs thousands of people, and its melting supplies the populations with drinking water and even energy thanks to hydroelectric generation. Neither one nor the other has stopped scientists from referring to Dagu as a “dying glacier” or “a terminal patient.” Thus, in such a heartbreaking way, he defined it a few months ago Wang Feiteng, glacier expert and member of the Chinese Academy of Sciences (CAS). Is your condition that serious? The data are certainly not encouraging. In an article published in 2025, the Chinese organization recalls that since the 1960s its ice has “fragmented into scattered remains” and the frozen surface of the glacier has been reduced more than noticeably. And the trend does not seem to ease. “During the last four years the terminal end retreated another 20 meters,” warn from the academy, which insists that if nothing stops the process the situation of the glacier will be critical and irreversible at the end of this same decade. “Without urgent intervention, the Dagu glacier will disappear by 2029.” Beyond Dagu. The Chinese academy is not the only one to warn of the degradation of the environment. In 2003 Bloomberg dedicated him a chronicle in which he already pointed out that in the last half century alone the glacier has lost more than 70% of its ice. Regarding the reason, researchers have few doubts: The retreat of the ice mass is explained by the climate and the increase in temperatures. The problem is actually much bigger. Dagu may be one of the most vulnerable, but China has many other glaciers spread across its vast geography. Many. It is estimated that about 69,000, the tenth part of the glacial mass of every planet. And only between 2008 and 2020 its frozen surface receded by about 6%. If we broaden the perspective, since the 60s it has shrunk 26%. A blanket for the sick. Dagu’s situation may be critical, but… “As a doctor, can one just walk away?” he wonders Wang Feiteng. Convinced that the answer is ‘no’, a few years ago he and his colleagues decided to apply a striking strategy on the Tibetan glacier. They are dedicated to covering part of their frozen surface with a blanket that protects it (at least in part) from the effects of global warming, slowing down the loss of ice. It may sound strange, but the key is in the physical properties of that ‘protective quilt’. What they use are “glacial blankets”layers that stand out for their reflective capacity and provide thermal insulation, minimize the absorption of shortwave radiation and improve the albedo of the glacier, that is, the proportion of reflected solar radiation. The result? Less ice loss. The technique is not exactly new. It is inspired by what they already wear decades doing the ski resorts of Austria or Switzerland to protect the snow, although the approach does change. The idea was put into practice in Dagu in 2020 with six rolls of white cloth covering a selected area of around 500 m2. And does it work? It seems so. The program has been attractive enough to attract the attention of UNESCO, which a year ago published an article by professors Kang Shichang and Du Wentao, both linked to the CAS, in which some results of the experiment are described. To begin with, experts have found that the melting rate in the area covered by the glacial blanket was reduced by 34% between 2020 and 2021. “Even a year after removing the fabric, the area melted 15% slower due to the extra ice,” clarify from the CAS. The scientists were not limited to Dagu. In an attempt to go further, they used “more advanced nanomaterials” to cover a section of the Urumqi glacierin the Tian Shan Mountains. Thanks to the use of nanofibers, the researchers claim that they have managed to reduce the melting rate up to 70% in summer. The key is in a new material that, according to a team from Nanjing University, is capable of reflecting more than 93% of sunlight and dissipates the heat to which glaciers are exposed, reducing ice loss. Not everything is advantages. The results They are hopeful, but they leave some questions raised and also have limitations, such as recognize Kang Schichang and Du Wentao: “Covering glaciers with blankets has been mostly applied to small, tourism-focused glaciers on the brink of disappearance. While it has been proven effective in slowing their retreat, it poses environmental risks, high costs, and can only be applied in small environments. Large-scale retreat of glaciers cannot be addressed using nanomaterials alone.” The Chinese Academy itself recognize that Dagu is “an atypical case”, since unlike most of the glaciers in China, which are remote and difficult to access, this one “is located in the center of an urbanized tourist destination, which has electricity and access to water all year round.” That’s important for several reasons. First, because it has generated an infrastructure that makes it easier to deploy programs such as blankets or the … Read more

AI saves you eight hours of work a week. As long as you’re the boss and you don’t have to use it yourself

The AI ​​that was going to change everything and revolutionize our work He doesn’t seem to be doing any of that at the moment. What there is is a great polarization between those who believe in that promise and between those They do not see it at all clearly or they fear it. And if there is a place where this love-hate for AI is palpable, it is in companies, where CEOs see things in one way and employees in a quite different way. what has happened. The consulting company Section has conducted a survey of 5,000 workers and managers in US companies with a fundamental question: How many hours of work per week is AI saving you? Survey results, displayed in The Wall Street Journalsay a lot about the vision of CEOs and employees about the impact of AI tools. Source: WSJ. CEOs love her, employees not too much. According to data from that survey, two out of three employees indicated that AI does not save them time at work or that at most it saves them less than two hours a week. These responses contrast with those of managers and CEOs: one third affirm that it saves them between 4 and 8 hours, another third affirms that it saves them 8 or more hours, and the other third affirms that it saves them 4 hours or less. The big difference is precisely in this negative view: 40% of employees say that they do not save any time, and only 2% of CEOs agree with that opinion. AI screws up more than anything else, some say. A user interface designer named Steve McGarvey indicated in that text how managers “automatically assume that AI is going to be the savior (of the business).” His experience is different, however, and he tells how “I have lost count of the times I have looked for a solution to a problem, asked an LLM, and they gave me a solution to an accessibility problem that was completely wrong.” And it’s not that big of a deal. This professional also indicates that he uses Perplexity as an assistant to research on various projects and that it has saved him time. However, part of their job is to ensure that visually impaired users can access websites, and chatbots have not been of help in that task. The employees are somewhat afraid. There’s another important aspect to the findings: Employees were much more likely to report feeling anxious or overwhelmed by AI than excited by it. That 40% who responded that it did not save them time added that because of them they would never use AI again. Employees are the ones who are most overwhelmed by AI, managers are the ones who are most excited about it. Source: WSJ. For now AI is used like Google. But there is another problem and that is that many of these professionals are using AI as an alternative to the traditional search engine from Google. They do not use it for practical applications of their work—perhaps because they do not know how—and, for example, it was used much less for topics such as code generation or data analysis. It saves me time, but like it doesn’t. Software companies like Workday participated in the survey and pointed out an interesting fact: this technology imposes an “AI tax” in terms of productivity. Although 85% of its 1,600 employees surveyed indicated that they save between one and seven hours a week thanks to AI, that doesn’t help them much: Much of that saved time ends up being used to correct errors made by AI or modify content generated by AI. AI isn’t much use (yet). An additional and also recent survey conducted by PricewaterhouseCoopers focused on 4,500 CEOs. The result: only 30% of them were confident that there would be an increase in revenue thanks to AI, although they admit that having a good AI foundation can help boost that return on investment. The adoption of AI, however, at the moment is not compensating them too much, and only 12% of companies claim to have obtained benefits in revenue or costs, while 56% claim to have “not obtained anything” with that investment. These data are in line with those of the MIT study of August 2025 according to which 95% of pilot projects with generative AI were not paying off to companies. But. The data is negative, but there may be factors that point to a change in trend. The surveys do not indicate how much time users are spending learning how to use AI versus the time it saves them. The benefit may be negative now, but in the long term it will be positive. Furthermore, there are sectors in which AI has clearly become a clear tool to assist workers, as in the field of programming. Although there is, of course, a necessary phase of code review that AI generates, the massive use of these tools indicates that productivity may have gained in whole.

Barcelona believes it has a night security problem. So you’re going to leave the Christmas lights on all year long

Vigo risks losing his position as “city of lights” (from Spain). Although the Galician City Council usually displays its Christmas decorations already in July and boasts every year of the millions and millions of LEDs that adorn its streets for almost two months, from November to January, there is another city that is about to raise the stakes: Barcelona. There the Consistory has decided maintain part of the lighting for the festivities Old City during the remainder of winter. Their reasons actually have little to do with Christmas. Lights, lights and more lights. Christmas may be over, but in Spain it is becoming common for us to talk about its lights for months and months. In Vigo they do it because the City Council begins to hang them in the middle of Julywith the thermometer flirting with 30º and the city full of tourists in shorts and flip-flops. Now they will do it too in Barcelonaalthough for other reasons. What do they want to do there? The news I advanced it on Monday The Vanguard: Barcelona is finalizing a plan to improve the lighting of some of the narrowest (and darkest) streets of Ciutat Vella, taking advantage of part of the decoration that was installed there this Christmas. That is to say, in the absence of traditional streetlights, garlands strung between facades are good. Although Jaume Collboni’s team has not yet revealed the details of the initiative, the idea does seem clear: it is not so much about neighbors, merchants and tourists continuing to walk for months under decorations of Santa Clauses, Three Wise Men and Christmas trees, but rather about maintaining the most ‘timeless’ designs. Walking under light bulbs. The key is therefore to take advantage of decoration that does not clash with the rest of the winter. To reinforce it, the municipal government also proposes maintaining the garlands that the merchants themselves have placed. In the Gòtic there are businesses that have been hanging decorative lights on their own, although as these were private initiatives they encountered challenges such as the passage of garbage trucks or some parades. Where, when and how. While waiting for the City Council to provide more details about where, when and how the initiative will be deployed, The Vanguard has advanced some keys: the measure will focus on points in Ciutat Vella, Gótic and Sant Pere streets, Santa Caterina and Ribera that aspire to improve their lighting. Regarding the calendar, councilor Albert Batlle explains that the Consistory proposes keeping the lights for several months: “The will is that the measure be implemented, now and in the future, during the winter time period, approximately between the last weekend of October and the last weekend of March.” Two keys: trade and security. Batlle too confirm that the measure pursues two objectives: to favor the businesses and residents of the area and to put an end to alleys in which pickpockets find refuge. “We want to improve the lighting of some small streets in Gòtic and Sant Pere, Santa Caterina and la Ribera to promote commercial, cultural and social revitalization, and also to improve the feeling of security, especially on days with fewer hours of daylight,” he adds. “We are working on the formula to enhance this network.” “They give them more qualms”. The measure appears to have had good reception among the businesses in the area, which even proposed expanding the list of roads that were initially going to benefit from the lights. “If the streets are more illuminated, walking becomes safer and commerce will benefit,” recognize to The Newspaper David González, from the Via Laietana Merchants Association. Proof of how convincing the measure is is that at the time some businessmen from Born they already started to hang garlands at your own risk. “People go along Paseo del Born very happy because the promenade and the streets are usually well lit. But the dark alleys make them hesitant.” The idea has also been found with detractors who consider it a patch. But… Does it work? Although he has achieved reduce your crimeBarcelona usually appears in the area highest of the rankings about the cities insecure from Spain. The key is whether more public lighting will translate into greater real safety, a question that has generated debate in recent years. What they do seem to confirm cases like that of Vigo is that a good commitment to street lighting (even if it is seasonal) serves to attract thousands of visitors.

You still don’t know when you’re going to receive them.

Renfe does not know when it will receive the last three Avril trains that are missing from the order of 30 units which he commissioned from Talgo. Just like they count From El Español, the public operator acknowledges that it has no information or planned dates for its delivery. Talgo, for its part, refuses to give explanations and says that it does not report on its projects. This push and pull and uncertainty around trains aggravates a relationship already deteriorated by more than three years of delays. It is not known where they are. Renfe sources recognize openly that they do not have information or scheduled dates to receive these three pending units. For its part, Talgo hides behind its policy of not sharing details about ongoing projects and leaves the responsibility of reporting on a situation that the operator itself claims to be unaware of in the hands of its client. The relationship between both operators is at its lowest point, a relationship that began to fracture with the first delays of the model 106, known commercially as Avril. A troubled history. The 27 Avril trains that are already part of the Renfe fleet There have been numerous incidents since April 2024, when deliveries began. The most serious episode occurred in September, when the operator was forced to withdraw the Avlo service on the Madrid-Barcelona route due to crack problems in these trains. The last three convoys received came into operation in June in the Galicia-Madrid corridor, where the majority of these units are providing service to replace some Alvia models. 116 million withheld. The accumulated delay of several years led Renfe to impose a penalty of 116 million euros on Talgo in July 2022. Sources from CincoDías they claim that the manufacturer has provisioned this amount in its accounts, but has not made the payment, maintaining that the delays were due to causes beyond its control. Meanwhile, Renfe maintains withheld the planned payments to its supplier, although the paralyzed figure still does not reach 75% of the total penalty. The 107 series, the next open front. The situation threatens to become even more complicated. Talgo must also deliver 13 trains of the 107 seriesa project that is already delayed compared to the dates planned for 2024. The Ministry of Transport has recently warned of possible new sanctions for this non-compliance. This model is being configured through the transformation of hotel trains and the use of 26 power units acquired for 204 million euros. The resulting material will allow driving at 330 kilometers per hour with tread adaptable to different track widths, a crucial capacity for services such as Avant and to reestablish Avlo in Madrid-Barcelona. Frustrated plans in France. The destination of the pending trains has also changed from what was initially planned. Renfe planned to allocate some of the missing units to its operations in France and was pending approval of model 106 in that country. However, the development of this plan has paralyzed “given the successive difficulties and delays that the deployment of its high-speed service offering in France is suffering,” as the company warned a few months ago. Restructuring underway. In parallel to these delivery problems, Talgo faces an extraordinary meeting this Friday in which its new shareholding structure and the co-financing of its debt will be put to a vote. The Basque consortium led by José Antonio Jainaga has acquired 29.7% of the capital for 156.6 million euros, together with the Finkatuz fund of the Basque Government and the Vital and BBVA foundations. The operation includes a capital increase of 45 million by SEPI, which will acquire 7.88% of the company, and the issuance of 105 million in convertible bonds. The challenge of regaining trust. The Minister of Transport, Óscar Puente, declared that his first contact with the next president of Talgo will be precisely to find out the status of the 107 series and settle the issue. Renfe awaits the appointment of the new person in charge to address the pending compensations, which it does not plan to give up. The key for the manufacturer is to increase its industrial capacity and above all avoid further delays in deliveries, with an order book that exceeds 4.8 billion euros and could reach 7,000 as the company consolidates its new structure.

Every time you think you’re eating poorly lately, think about these Neanderthals who ate their neighbors.

Approximately 40,000 years ago, a group of Neanderthals captured girls and women, took them to the vicinity of the Goyet caves (in present-day Belgium) and ate them. And no, it’s not a figure of speech. What is a girl like you doing in a place like this? Although the third Goyet cavern has been studied since the 19th century, it was not until a few years ago that tomographic techniques, ancient DNA analysis and isotonic measurements have allowed us to fully understand what was happening in the heart of the mountain. And we have seen the best example a few days ago in Scientific Reports, Quentin Cosnefroy and a large team of European researchers have managed to identify a minimum of six individuals among the mass of bones to be studied. At least four were adult or teenage women of short stature and surprisingly fragile bones. And that in itself was quite curious: why was the proportion of women so high? But it wasn’t the most curious thing: the most curious thing is that they had been eaten. Hunger. According to the analysis, virtually all of the bones show cut marks, fracturing for marrow extraction, and other signs of processing for human consumption. But the most striking thing is the selection: it is not a random group, but a very specific demographic sample. I have already said the key: the bones were too graceful to be Neanderthal bones (who, remember, populated the caves at that time). The isotopic studies showed that none of these individuals came from the vicinity of Goyet: that is, they were women from other groups who (as I said) were captured and taken to the cave to be consumed with tools. They were a banquet. And no, I’m not going overboard with sensationalism. The same study acknowledges that the statistical probability of finding such a gender and age composition is ridiculous. “The exclusive presence of women and children in the Goyet complex does not respond to chance or a sample of natural mortality. It is a deliberate selection,” said Christian Pérez. And he was right. The only reasonable explanation is exocannibalism; something that had only been identified in modern ethnographic contexts as a form of violence towards groups (in the context of tribal wars). As the authors pointed out, this interpretative key is what can help us understand what was happening. The last living Neanderthal. Little by little, the question of what happened to the Neanderthal universe becomes more accessible to us. In fact, “the appearance of extreme behaviors such as selective cannibalism could be interpreted as an expression of growing tensions” and that clears up many doubts about what could (and could not) happen. As much as the theories on assimilation gain strengththe truth is that this admiration was not a bed of roses.
