hands

While half the world is worried about aging, one industry is rubbing its hands: the elevator industry

by

The world ages. And at a good pace too. If the World Health Organization (WHO) hits the nail on the headin 2050 the percentage of people over 60 years of age will double that of 2015. From representing 12% it will become close to 22%. Beyond the percentages, this aging translates into challenges in economic, health and social matters. Also in juicy business opportunities, like the one that he thinks he has before him the elevator industry. In their case, an older world will be a world with more work. What has happened? That TK Elevator has shaken the elevator sector by openly recognizing that the gradual aging of the planet (very visible already in Europe or countries like Japan either Korea) represents a lucrative business opportunity. The reason is simple: the more elderly, the greater the need for elevators in buildings. Especially since these and their services are also aging. “A growing trend”. If TK’s words have generated so much expectation, it is because it is not just any company. The firm, based in Düsseldorf, is a heavy weight within the sector, where it is responsible for both manufacturing machinery and maintaining it. Their models can be found in emblematic skyscrapers in New York, although the bulk of their business comes from much more modest buildings occupied by homes, offices or shops. His prediction about the future of the sector in an increasingly aging world has not been made anywhere either. has shared it with one of the most influential newspapers in the US, Financial Times. “As the population ages there is a need to install elevators. We see this becoming a growing trend,” recognize the firm’s executive director, Uday Yadavl. The example of Japan. During his interview, Yadaval cited a specific case: Japan, perhaps one of the countries that is most clearly suffering from the winds of demographic winter. Although all your attempts to reactivate its population engine (and there have been many), the birth rate continues at levels historically low while on the streets it is increasingly easier to find elderly people. According to Our World in Datathe country has the highest “old-age dependency ratio” (the ratio between people over 64 and people of working age) in the world: in 2021 it exceeded 50%, which means that there are only two people of working age for every elderly person. And since then demographic indicators have not exactly improved. It is estimated that about 30% of the country’s population is 65 or older, which is equivalent to tens of millions of people. A widespread phenomenon. Japan is not the only nation facing an aging population, a problem with which Europe fights and other countries, such as South Korea either China. In general the WHO has warned that the trend seems to be accelerating globally and remember that in 2020 the number of people aged 60 or over exceeded that of children under five. “In 2030, one in six people in the world will be 60 years old or older,” insists the WHO, recalling that by then the world population over 60 years old will total 1.4 billion people, well above the 1,000 in 2020. Demographics (and more). It’s not just that more and more older people live in cities and need elevators to get to their homes, it’s that the buildings themselves need renovations. At the end of the day, we age… and the blocks in which we reside. Yadav estimates There are about 22 million elevators worldwide, of which a third (30%) are more than two decades old. In practice, this translates into an immense number of facilities that probably need improvements and tune-ups, a demand that, assures the manager from TK Elevator, is already “growing in a meaningful way.” “More than remarkable”. Although his weight in the sector gives him special relevance, Yadav is not the first to have publicly recognized the good forecasts that the elevator industry has. Last summer Roland Berger published a report in which he provided several insights into the global elevator market, valued according to his calculations at 107 billion dollars. After “several ups and downs” in recent years, marked by COVID-19 or the real estate crisis in China, companies now face a “more than notable growth panorama.” A trend that connects the sector with the flourishing silver economythe economy driven precisely by aging.

Spain’s main problem is not weapons, fighters or drones. It is the number of hands you need to use them.

In recent years, the defense debate in Europe has revolved almost exclusively around money and technology. It talks about percentages of GDPmodernization and new systems capable of changing the battlefield. However, there is a much less visible factor that ends up being decisive when it comes time to turn plans into reality. A decade of losing muscle. The news Europa Press gave it. Since 2010, the Spanish Armed Forces They have lost 13,300 troops and they carry a structural deficit that the Military Life Observatory describes as chronic. As of January 1, 2025 there were 116,739 soldiers in active service, very far from the legal minimum of 130,000 established by the Military Career Law. The gap ranges between 13,000 and 23,000 uniformed personnel, a figure that is practically equivalent to an entire army within the system itself. Objectives that are not met. Several weeks ago another news item put the target on an enlightening fact: the regulatory framework establishes a maximum of 50,000 officers and non-commissioned officers, but there are only 40,656 dashboardsincluding 227 generals, leaving a wide margin unfilled. In the troops and Navy, the budget ceiling has limited staff numbers to 79,000 for years, although it is barely exceed 76,000 troops. The distance between what is provided for in the law and what is available in the barracks is not temporary, but sustained over time. More budget on weapons, fewer hands to operate them. The strategic debate in Europe has turned towards the modernization of systems and increased spending up to 2.1% of GDPbut the emphasis has not been transferred with the same intensity to the staff. Weapons programs and technological capabilities are expanding, but the number of military personnel is barely growing or even go back. Hence all this leads us to another reality very different from what we usually think: Spain’s main problem is not fighters, drones or new systems, but rather the great number of staff missing to use them and keep them operational. A 2025 that closed in negative. Despite the government’s commitment to increase staff by 7,500 personnel in four years, 2025 ended with 832 fewer soldiers than the previous year. The drop was especially pronounced at the officer level, where a thousand professionals they abandoned or passed to the reserve without sufficient replacement. Although non-commissioned officers and troops registered slight increases, the global balance was once again negative at a time when the international environment demands just the opposite. Lack of interest. The interpretation of these data leaves little room for doubt. The number of places offered has increased, but the proportion of applicants per vacancy has decreased worryingly. In the troop area the ratio has fallen to 4.2 applicants per placefar from the levels of a decade ago. In officers and non-commissioned officers, the descent is even more pronouncedwith fewer candidates and a worse selection margin, which limits the quality of replacement and anticipates problems of generational change. Salaries, mobility and little incentive for promotion. There is much more, as the report points to lower salaries to other bodies of the State and to an accumulated loss of purchasing power that discourages a military career. Constant mobility can imply a higher cost of living and low salary compensationleading many to give up promotions. The result is that “little interest” in progressing within the institution and a structure that ages without sufficient renewal. Stressed and aged. The other elephant in the room: more than a third of the dashboards exceeds 50 years and the troops also show progressive aging, while the reservists have decreased steadily since 2014. For its part, female participation grows slightly up to 13.1%above the NATO average, but it does not compensate for the overall loss of troops. I remembered the newspaper El Mundo that the system is also facing an increase in harassment complaints that adds reputational pressure at a time of low recruitment. Material capacity without critical mass. All this leaves a more or less illuminating map. Spain is investing in capabilities and is committed to increasingly demanding international missions, but it does so with less staff that fifteen years ago. The organizational structures and operational commitments have not diminished, rather the oppositewhile the human base it doesn’t stop shrinking. From that perspective, everything indicates that, if the trend is not reversed, the country may find itself with a future where the Armed Forces are modernized in equipment, but without the critical mass necessary to sustain them over time and respond reliably to an increasingly demanding strategic environment.

Mexico needs the Mayan Train to work. And they are so desperate that they have put it in military hands

by

There are many ambitious trains, but like the Mayan Train there are not as many. And it’s not because this train stands out for its speedby go through impossible tunnels either for luxurybut because few trains in the world must support a load as heavy as this one: being the backbone of the tourism in Mexico. Born with tremendous ambition, he started his engines with promises of wealth. AND is crashing resoundingly. So much so that Mexico has completed the transfer of control of the train to the Secretariat of National Defense. Army, to manage. FONATUR Tren Maya was the organization attached to the Ministry of Tourism that, since 2018was responsible for leading and managing the project. However, things did not work out, the plans were not fulfilled and, already in September 2023, when Obrador saw the arrival of the deadline to launch the train, he began to take steps for the Secretariat of National Defense to take control. After a series of steps, and as we read in Chroniclerit was at the end of 2025 when the process was finalized for Tourism to stop operating the train and Defense to take charge of it. Goals. The program has the following goals: Consolidate responsible transportation with the environment and society. Offer a safe and innovative transportation system. Ensure profitability through efficient management. That last point sounds like an ax to the previous management, but they are going to have a difficult time. Indifference. It was a few weeks ago when, in an article published by El País, the figure was revealed: the Mayan Train moved 5% of the expected demand. Neither tourists nor locals seem to have the slightest interest in a vehicle that was born to unite the different regions of the Yucatan Peninsula. Just because, It is the tourist jewel of Mexicobut also a tremendously unequal region in which Chichén Itzá brings together the majority of archaeological tourism, to the detriment of the others. And it seems that the train is not solving this. The report states that, during the first year, it transported about 3,200 passengers daily. Do we contextualize? The forecasts were for 74,000 passengers per day. Billionaire failure. It is a hard blow for a project that was already born on the wrong foot. It was the most ambitious project of the previous president, Andrés Manuel López Obrador, one without private or foreign capital, 100% Mexican, which caused headaches practically from the beginning. Obrador took advantage of that public investment, but from an initial budget My dear between 120,000 and 150,000 million Mexican pesos -about 7,400 million euros-, it ended up costing more than 500,000 million pesos -about 24,500 million euros- for 1,500 kilometers of roads. Current itinerary Expansion. The change in management is not symbolic: a series of actions have been proposed to expand services. On the one hand, passing under military control implies that seeks to operate with greater security for passengers, especially in areas where conflicts with drug traffickers are a problem. Greater professionalization of management is also sought through an administration under military command, but in the background there is an expansion plan. The aim is to transport cargo such as food for isolated indigenous communities or medical goods. Also that the train serves as a humanitarian corridor in the face of misfortunes, and for this they will create more than 3,000 additional kilometerswith an extension to Puerto Progreso. Will anything change? It’s the million dollar question. On the one hand, the Sheinbaum Government has made it clear on more than one occasion that they want the railway to be the backbone of the country not only for the transportation of people, but also as a freight corridor. The goal By 2030, four million passengers per year and 4.7 million goods per year will be moved thanks to the integration with the Interoceanic Corridor of the Isthmus of Thuantepec. Come on, turn the train into something that can compete against the Panama Canal. But of course, it can become a way to move goods, but we have to see if passengers use it to move. In statements to El País, it is more profitable for locals, and it is also more practical, to get around by bus. And tourists usually arrive in Yucatán with already established itineraries that do not require train services. And, on the other hand, there are the controversies associated with the military and the construction sections that they were in charge of in the past. Sections 5, 6 and 7 were commissioned directly to SEDENA, and there are not few cases of environmental violations, social conflictsviolation of human rights against indigenous Mayan communities and extra costs associated with those sections under military control.

The community has made it clear that they do not want AI in Windows and Microsoft has ignored them. So they have taken the law into their own hands

by

Microsoft’s obsession with putting AI in every corner of Windows is logical at the current time (after all, it’s what everyone is doing). The problem is that the community has been very clear about this: they don’t want to. Microsoft has continued with its plan flood Windows 11 with AIbut we already have a way to avoid it. Winslop. The name comes from the play on words between Windows and Slop, which is the term used to refer to ‘AI garbage’, that is, very poor quality content. This is a free tool whose purpose is to eliminate all traces of AI from the system. Its creator makes it clear that he is not anti-Windows, in fact he states that he likes the platform, what he doesn’t like is the direction it is taking. CleanIA Windows. Winslop is totally free and you can download it from Github. The interface looks like old versions of Windows and consists of a list with all the changes that we can apply. There is an option that inspects the system and proposes the changes to be made, or we can check the boxes we want, depending on the level of cleaning we want. The list is quite long and is divided into categories, these are some of the functions we found: System: shows details if there is a blue screen instead of a sad face, optimizes system sensitivity, speeds up shutdown time… Microsoft Edge– makes it not the default browser, disables the Copilot icon, removes the shopping assistant, does not show sponsored links when opening a tab… Interface: Turn off transparency effects, hide taskbar search, turn off Bing search… gaming: Disables DVR recording, power throttling and visual effects. Privacy: disables activity history and location tracking Advertisements– Remove ads system-wide. AI– Hides Copilot from the taskbar and disables Windows Recall. Bloatware. There is more. Winslop is divided into three tabs: Windows 11, applications and extensions. From the apps section we can eliminate pre-installed applications such as Bing News, Bing Weather, WindowsCamera and many more. As in the other section, pressing the ‘Inspect System’ button gives us a list of suggestions to eliminate and we mark the ones we want. It’s not the first. Recently we told you about a tool that was born with the same objective (although with a name with less punch), RemoveWindowsAI. Like Winslop, it also disables all AI functions, but beyond its functions, the important thing is that its simple existence was already a symptom of community fatigue. The fact that another app has come out only confirms it. The PC IA. The obsession with turning Windows into an agentic system has collided head-on with what the community is asking for, to the point that Microsoft is losing favor with users. A year ago PCs with AI promised to be a revolutionbut they have come face to face with reality and even historical brands like Dell are changing their discourse. Microsoft is left alone.

Their lands are in the hands of only 421 landowners

by

While the whole world watches how digital and financial power is concentrated in the hands of a handful of millionaires in Silicon Valley, Scotland stands out for something much more physical but which serves as an example that this concentration of power in a few hands has been happening for centuries: land. Only 421 owners control around the 50% of private rural land of the country. It is a figure that is difficult to find in other countries and makes Scotland practically unique in Europe. What is surprising is not only the concentration of land in a few hands, but its persistence. While much of the continent fragmented property after revolutions, agrarian reforms or wars, Scotland has reached the 21st century with a territorial structure that has barely changed in centuries, maintaining its feudal structure. An anomaly with historical roots. The key to this territorial anomaly is intrinsically linked to its history. Scotland never experienced a radical break with its system of large estates. The power of the tribal clans first and the landowning aristocracy later consolidated enormous areas under a single owner. When other European countries redistributed land among their citizens, in Scotland the right to property remained almost intact. The historical studies reveal that already at the end of the 19th century the land was concentrated in a few hands, and the arrival of the modern State did not substantially alter that map. The result is that Scotland enters the 21st century with a property map that appears frozen in time. A European rarity considered “exceptional”. Why wasn’t it distributed? The absence of a profound territorial reform was not accidental. Unlike France, Germany or the Nordic countries, there was no massive redistribution of the land when feudal privileges were abolished. One of the reasons that weighs most heavily in this “anomaly” is that in Scotland there was no revolution or civil war that promoted a social change and land ownership, as happened in Europe with the World Wars, with the French Revolution, with the different dictatorships. Thanks to this territorial calm, the United Kingdom avoided major agrarian redistributions and protected private property as a pillar of its economic and political system. From lords to billionaires. For centuries, the great owners were dukes and great lords of aristocratic families. Today the profile is more diverse but equally wealthy. Scotland has become a magnet for international millionaires, heirs to large fortunes, investment funds. The reason why has attracted so many millionaires It is simple: few regions in Europe offer such large areas of land and the legal stability with respect to territory that Scotland offers. This is the case of Danish businessman Anders Povlsen, fashion magnate at the head of brands such as Jack&Jones and one of the main investors in the online giant Zalando, which in recent years has become one of the largest private landowners in the United Kingdom. Along the same lines we find the billionaire heiress of the Lego empire who, according to published The Timeslittle by little has been acquiring huge plots in the Scottish Highlands. Sheikh Mohammed bin Rashid al-Maktoum, emir of Dubai, is also among the new landowners who is acquiring land in Scotland at a frenetic pace. He already has eight houses in that area Owning land is a sign of power. In the Middle Ages, owning land was a symbol of economic power since a productive benefit was obtained from the crops. Today, it also maintains that powerful status, although for different reasons. Whoever controls thousands of hectares of land influences housing development, in energy projectsin land use and in the future of entire communities. a study of the Scottish Land Commission warns that such extreme concentration of land in the hands of a few landowners can limit local democracy and slow rural development, as a few people make key decisions about huge territories and those who live in or around them. Reforms that advance slowly. The Scottish Government has attempted to correct this anomaly with new territorial reform laws. Transparency has been improved, public procurement has been facilitated and the introduction of “public interest” mechanisms for large urban plans is being debated. However, both analysts and British media agree that current tools are completely insufficient to substantially change the balance on Scotland’s land ownership map. Concentration remains the norm, not the exception. Instead of dividing, they regroup. The most paradoxical thing about this situation is that, despite the political debate, recent data They show a reconcentration driven by the new millionaires turned landowners, who are buying large tracts of land and their surroundings. That is, properties that already belonged to others are once again concentrated under a single owner. He follow-up carried out by former MP Andy Wightman reveals that most big land deals end up in the hands of those who were already big landowners. These operations are supported by a real estate market that works in their favor due to high prices, a low supply and buyers with great financial capacity. The high prices of farms make them inaccessible to local communities or farmers who cannot compete against the financial capacity of millionaires. The gentrification has arrived to the Scottish Highlands. In Xataka | In California, the funds discovered that there is no investment more profitable than farmland.

Apple, Google and Samsung promised them happily with 5,000mAh batteries. Until China came to rub their hands on their faces

by

The person writing these lines has an American mobile phone—made in China—with a little more 5,000mAh. A figure in which giants like Apple, Samsung or Google have been comfortably installed for years. Meanwhile, in China, Honor has just made official a phone with a 10,000 mAh battery. The launch is not surprising just because it has managed to literally introduce a powerbank inside a smartphone. It is surprising because it breaks a barrier that until now no one had dared to cross. Not due to lack of possibilities, but due to industrial inertia. The aforementioned. Honor has made the Honor Win and Honor Win RT. Two phones that, in addition to having the best Qualcomm processorshave a 10,000mAh battery made of silicon-carbon technology. The message is clear: this is not a typical high-end, it is proof that China is the leading benchmark in batteries for smartphones. thickness. For years there has been an unwritten but unquestionable rule: more battery means more thickness. The 10,000 mAh were reserved for rugged, bulky mobile phones designed for very specific uses. These Honor Win break that logic. They are thinner than a iPhone 17 Pro Maxbut with double the energy capacity. There are no gimmicks, fine print or marketing exercises: it’s a real leap in energy density. How did they achieve it?. Honor has not specified how they have managed to take the capacity to such an extreme but the person responsible is clear: silicon-carbon. This technology has been demonstrating for years that it is possible to introduce much denser batteries in the sizes in which lithium has already reached its ceiling. Chinese mobile phones have been standardizing for more than a year batteries over 7,000mAhand Honor’s move to reach five figures marks what aspires to be a new standard. The cons. Silicon-carbon poses certain challenges, and the first is degradation. These batteries, especially in their first generations, They seemed not to be at the same level as classic lithium batteries. Over time, the promised charge cycles are virtually identical to those of traditional lithium batteries (more than 1,500). The second is the cost: producing this type of cells is more expensivewhich partially explains why, for the moment, these figures reach China first and not global markets. In fact, a common practice is to find models whose Chinese version has more battery than the global version, reserved for the rest of the markets. A third key point is related to security and regulation. Denser batteries require stricter controls, and Western regulatory frameworks are not always prepared to adopt these types of advances so quickly. None of this invalidates progress. It simply explains why Apple, Samsung or Google have not yet made the leap. It’s not that they can’t: it’s that they haven’t wanted to take the risk… yet. China is going to force a move. The 10,000mAh batteries are, without much room for doubt, one of the biggest technological leaps in the world of smartphones after the arrival of AI. A figure that will allow us to normalize the three days of average use without going through the charger. The leap is so relevant that, whether they like it or not, “traditional” manufacturers will have to start making a move, as they had to start doing with fast charging systems. Samsung has already started implementing the 7,000mAh in phones like the Galaxy M51but its high-end is still at the 5,000mAh barrier. Google also moves in the 5,200mAh and Apple… is Apple. With a greater or lesser pace of implementation, these manufacturers are forced to keep pace with China in these advances. And that translates into admitting that we were wrong about lithium.

Google is serious about putting data centers in space. Elon Musk and Jeff Bezos rub hands

by

While there are municipalities debating whether to let big technology companies install data centers in their domainsGoogle wants a strike further: taking the data centers to space. Google. The company revealed its intentions a few weeks ago and your Suncatcher project wants to install two prototype satellites before 2027. Curiously, Elon Musk and Jeff Bezos are more than delighted with the idea of ​​their rival. Suncatcher Project. Push the capabilities of the artificial intelligence requires that we train it and, for this, they are necessary huge data centers with spectacular computing power. The problem is that the energy needs of these facilities They are astronomical, becoming resource sinksmaking oil companies set aside their renewable energy plans and even raising the opening of “private” nuclear power plants. Suncatcher couldn’t have a more appropriate name. In space, without the influence of the atmosphere, solar panels They capture the light spectrum in a different way, enough to feed those data centers that seem insatiable, and what Google proposes is to build constellations of dozens or hundreds of satellites that orbit in formation at about 650 kilometers high. Each of them would be armed with Trillium TPU (processors specifically designed for AI calculations) and would be connected to each other via laser optical links. Pichai puts the topic anywhere. Although 2027 is the key date, it is evident that Google is very interested in airing its plans because it is a sign of both technological power and an invitation for interested entities to invest in the process – and a way to continue inflating everything around AI-. And the person who is practicing this speech the most is the company’s CEO himself: Sundar Pichai. Since we learned of Google’s plans, Pichai has spoken of the topic in every interview he has given. It does not tell anything new beyond that hope of having TPUs in space in 2027 and the ambition that in a decade extraterrestrial data centers will be the norm. Musk and Bezos: competition, but allies. And if Google is interested in selling its narrative, those who are also interested are two of its most direct competitors: Elon Musk and Jeff Bezos. Both Musk with several of his companies and Bezos with Amazon Web Services are in the race for data centers and artificial intelligence. They have some of the largest on the planet, but they also have something that the rest of the competitors don’t: ability to launch things into space. Musk with SpaceX and Bezos with Blue Origin have the tools to put satellites into orbit, charging for each kilo they launch into space. And it is there, the more credible it seems that the future of computing is in low Earth orbit, the more economic and political sense they will make. SpaceX as Blue Origin. Both are Google’s competition, but also the option for Google to achieve its objective. And, ultimately, we keep seeing rival companies renting their services from each other. Data center fever in space. The truth is that, at first, it sounds like a crazy plan to build these extraterrestrial data centers, but from the most pragmatic point of view (removing logistics and the money that both development and each launch will cost from the equation), it is a plan that makes sense. In space, a panel can perform up to eight times more than on the Earth’s surface, in addition to generating electricity continuously by not depending on day/night cycles. It is something that would eliminate the need for huge batteries, but also for complex water-based cooling systems. And, as we said, Google is not alone in this. Currently, there is a fever for space data centers with big technology companies in the spotlight: Considerable challenges. Now, Google itself comment It will not be easy to carry out this strategy. On the one hand, the costs. The company claims that prices may fall several thousand dollars per kilo to just $200/kg by mid-2030 if the industry consolidates. They note that, in that case, the price of launching and operating a space data center could be comparable to the energy costs for an equivalent terrestrial data center. Another difficulty will be maintaining a close orbit between the satellites. They would have to be within 100-200 meters of each other for optical links to be viable. And most importantly: radiation tolerance by the TPUs. Google has been experimenting with this for years, but they must test the effects of radiation on sensitive components such as the HBM memory. Surely astronomers They will be delighted with this strategysame as with starlink. Image | THAT In Xataka | We are launching more things into space than ever before.

NASA needed to get to the Moon and had a problem with an insulating material. So it was put in the hands of the surfers

by

Now that we are immersed in the space race to reach Mars, it is worth looking back to see one of the most surprising anecdotes of the other race with which the United States achieved taking man to the Moon for the first time. And to achieve this they did not hesitate to use all available resources, from their best scientists to their best… surfers? Although it may seem like a joke, it took surfers to perfect the Saturn Vthe space rocket with which the Apollo missions took off between 1967 and 1973. The POT He had created a honeycomb-shaped insulator for his rocket, and needed specialists in the use of honeycomb-shaped materials… like that of the surfboards of the time. This story It was kept secret for years. But even though it ended up coming to light after a NASA engineer told it in an interview, it remains one of the most curious and unknown anecdotes of the space race. There are also references to it in documentaries such as one of the chapters of ‘Moon Machines’, available at YouTube. Surfers at NASA The second stage of the Saturn V, the S-II, was built by National American Aviation (NAA) in Seal Beach, California. It was composed almost exclusively of two tanks of oxygen and liquid hydrogen that, for logistical reasons, had to be placed almost close together and separated only by a thin layer of aluminum. But there was a problem, that the liquid hydrogen had to be kept at a temperature of about 20º above absolute zero, so They had to create a new insulator to cover your tank. They created one in the shape of a honeycomb, since the hexagonal design is the strongest and lightest in nature and we have been using it for thousands of years, but they could not get the insulating layer to stay stuck to the aluminum. Fortunately for the NAA their facilities were in one of the surfing capitals on the west coast, and their engineers realized that the surfers They also used honeycomb-shaped materials in their boards. They were therefore more experienced experts than any scientist when it came to dealing with these types of insulators, which is why they hired a few to design an effective way to apply it to the tanks. The surfers recommended applying the insulation with sprays with a foam that solidified forming hexagonal cells. The idea worked, the NAA finished the S-II, which was assembled with the rest of the parts of the Saturn V. The rocket took 24 astronauts to the Moon without any loss of useful shell, having only engine problems with Apollo 6 and Apollo 13.

A new turn to end the war in Ukraine has left the final outcome in the hands of a decisive point: 900 km

by

The latest diplomatic movement between the United States and Ukraine has crystallized into a peace draft reduced to 19 points which, according to both delegations, constitutes real progress with respect to the controversial document initial 28 points. That first draft, written largely with Russian participationcrossed multiple Ukrainian red lines and set off alarms throughout Europe. As things stand, the final decision is a little more 900 km. The new twist. In Geneva, after hours of tense negotiations that were on the verge of collapse, the team led by Andriy Yermak managed soften or reformulate most of the most problematic aspects. The new text, described as a “solid” body of convergence, integrates security guarantees, economic commitments and infrastructure protection in a framework that is no longer perceived like an ultimatumalthough it is far from resolving the most explosive core: the territorial question. That point (the possibility of giving up portions of the east) was explicitly “placed in brackets” for Presidents Trump and Zelensky to decide, a gesture that recognizes both the political gravity of the issue and the legal impossibility of resolving it without a national referendum in Ukraine. The revision of the draft also eliminates elements such as the limitation of the Ukrainian Armed Forces to 600,000 troops or a total amnesty for war crimes, but deliberately preserves the biggest obstacle. Thus, although the White House describes the process as “optimistic,” the heart of the agreement is suspended in an uncomfortable balance: moving forward without defining the most decisive point. The air battle. In parallel to the negotiations, a strategic reflection runs through the debate: no agreement will survive if Ukraine lacks of air guarantees real. Moscow has shown that your fastest and most effective way to break a ceasefire is violate airspace with missiles, drones, bombers or fighters. Ukrainian cities have been subjected to long-range attacks and coercion from the sky for three years, and the country has only avoided total collapse thanks to a makeshift patchwork of Western anti-aircraft defenses. They remembered the analysts at Forbes that any sustainable peace requires three pillars: an integrated defense network that connects radars, Patriot batteries, NASAMS, IRIS-T and aviation in a common operational framework, a modernized, numerous Ukrainian air force capable of maintaining continuous patrols with F-16, Rafale or Gripen equipped with AESA radars, long-range missiles and advanced electronic warfare, and a visible presence of allies operating from or within Ukraine, similar to the Baltic Air Policingto deter violations and react unambiguously to any incursion. Clarity. Furthermore, it was pointed out that the rules of engagement should be explicit: immediate interception of unauthorized aircraft, shooting down any vector that poses a threat and automatic retaliation against launch points if Moscow fires missiles after an agreement. Without this aerial architecture, a peace signed on paper would become a fragile parenthesis, exposed to a Russia that historically explores every void and tests every border. The stability of the future agreement depends both on the diplomatic text and the firepower that supports its lines. The point that no one wants to write. What happened in Geneva shows that diplomacy is advancing, but also that it is doing so with a limp. counted the financial times that the meeting began almost broken: the Americans, upset by previous leaks, arrived tense, and the Ukrainians, distrustful of the pro-Russian bias of the original draft. It took a long conversation. almost therapeuticbetween Yermak and the American delegation to reduce tension. Afterwards, both sides revised the draft point by point, eliminated the troop cap, rewrote the amnesty and adjusted key definitions. The Europeans (United Kingdom, France, Germany, Italy and the EU) joined later to coordinate priorities and synchronize postures. Subsequent statements reflect a “constructive atmosphere,” with Washington under self-inflicted pressure to present the document to Russia as soon as possible. Be that as it may, no technical correction can resolve the essential absence: the impossibility of deciding in that room about the territory. According to the Ukrainian negotiators, they did not have a mandate to give up a single kilometer, and the Constitution requires consultation to the population. Kyslytsya himself admitted that what is pending requires “leadership decisions,” a diplomatic euphemism to admit that what is unacceptable for Ukraine has been postponed, not eliminated. The 900 km as a judge. The peace draft can have changedbut the reality on the front changes even faster. As diplomats wrote, erased and rewrote sentences in Geneva, Russia intensified its offensive in multiple sectors: advances north of Huliaipole, increasing pressure towards Siversk and a siege that could be sealed in Pokrovsk and Myrnohrad. The front line, about 900 kilometershas become the silent arbiter of the negotiation: the more Ukraine retreats, the more strength Russia believes it has to demand concessions, and the more it resists, the more room Kyiv has to reject any territorial concession. The American and Russian proposal filtered It started from that premise: asking Ukraine to hand over areas that it still controls before it loses them. Zelensky, however, has reiterated that Ukraine will “defend its home” and that accepting territorial amputations would undermine not only its political legitimacy, but the very possibility of lasting peace. Time trial. The problem is that time on the front is against Kyiv. Russian advances, although extremely costly in men and material, are creating pockets of vulnerability and forcing to retreat reserves to cover cracks. And what is at stake in those 900 kilometers It’s not just terrain: is Ukraine’s ability to come to the table with a negotiating position that does not amount to staged surrender. Every kilometer lost on the map alters the draft in Geneva more than any paragraph. Between paper and the battlefield. What emerges from these three fronts (diplomacy, the sky and the line of contact) is a more or less clear picture: the peace agreement is closer in form, but not in depth.

There are people trying to kill migraine with surgery. Neurologists are putting their hands on their heads

by

Migraine is a relatively common neurological disorder among our population that can have dire consequences for those who suffer from it. as it can become disabling for several days in a row. This means that patients’ search for treatments has become desperate to avoid having to being locked in a dark room for several days without being able to go to worksince there is no cure. The problem is that the treatments that are proposed are sometimes not the best. Among these measures we have, for example, the famous piercing in the ear that promises control headaches or even botox therapy. But the reality is that now an operation is emerging that continues to raise doubts. What does it consist of? When suffering from disabling pain, the main thing for many patients is to eradicate it, and the reality is that they do not care how to do it. That is why trigger point decompression surgery, popularly known as “migraine surgery,” is beginning to become popular in the United States. And while in the United States it is gaining more and more ground, the Spanish Society of Neurology has raised the alarm due to its proliferation in private clinics by offering great results against this disease. His story. The story of this surgery does not begin in a neuroscience laboratory, as happens with other techniques that are put into clinical practice. To understand this technique we have to go back to the beginning of this century with the surgeon Bahman Guyuron who noticed something strange: many patients on whom he performed the lifting from the front, that is, the frontal stretch, they reported that after the operation their migraines had disappeared. From there, the theory of extracranial trigger points was developed. The hypothesis is that migraine is not just a brain event, but can be triggered by compression of peripheral nerves in the face and neck due to muscles or blood vessels. Surgery in this case basically consists of releasing these nerves through decompression or cauterization. of four specific areas of the skull: In the forehead region. At the temples. On the back of the head. In the nose area. The discussion. It is not logically conflict-free. On the one hand, there are American surgeons who They assure that between 70% and 95% of patients improve or eliminate their symptoms. However, when we turn to rigorous scientific literature, the numbers become considerably nuanced. The magazine Frontiers in Neurology, who analyzed the data of 627 patientsrevealed a very clear reality. Only 38% of patients undergoing this operation recorded a remission of headaches after 6-12 months. And this is a very controversial figure, since private clinics promise figures that are not what independent studies point out. The study explicitly warns that more elaborate and transparent tests are neededsince the risk of bias in patient selection is high. That is, those patients who are giving the best results are chosen, giving a success value that is not totally real as it does not follow the quality standards expected in a study. In Spain. Our country has gone up in arms against these types of surgeries that seem like a miracle, and the Spanish Society of Neurology (SEN) He does not see the physiological basis behind it that explains its effect. The first thing they see is that the studies are too small (which leaves the results obvious), but they also point out that migraine is a disease of the central nervous system and that “decompressing the nerves” outside the skull lacks biological plausibility. Specifically, the conclusion reached in the SEN is the following: There is no scientific evidence that currently supports that surgery has a therapeutic role for migraine. Therefore, any migraine patient is not recommended to undergo surgery for this disease. Migraine has been studied in depth, and there is no solid evidence that these nerves are compressed in migraineurs. And they go further by pointing out that “migraine has no cure, but there are many scientifically based therapeutic developments and more are to come.” Placebo effect. To understand it, we must know that surgery is an intervention that is imposed on anyone, and the simple fact of going through an operating room generates in a patient the feeling or expectation that they will be cured. That is why this is about measuring in the control groups, which are those patients who enter the operating room, but who do not receive nerve decompression (although they think they do). In these cases it has been seen that patients point out that their migraines have improved, when this is not the case. All motivated also because measuring the intensity of pain in a patient is not easy at all, as it is tremendously subjective, since each person perceives it in a specific way. Your application. In Spain, the technique moves in limbo. It is not financed by social security nor endorsed by the Network of Health Technology Assessment Agencies (RedETS), but it is offered on the private market with prices ranging between $5,000 and $15,000. But the recommendation of specialists in this case is that “any patient with migraine is not recommended to undergo surgery for this disease.” The only exception they make is that you are going to participate in a clinical trial.
