donations from parents to children have skyrocketed

by

In the offices of Valencian notaries there is a procedure that has been gaining weight in recent years, and at an astonishing speed: the donations from parents to children who want to have their own home. Since 2019, the region’s members have confirmed a “boom” both money deliveries (they have almost quadrupled in just over five years), and home transfers, an operation that has also multiplied. The objective is always the same: to help young people get their head into a market increasingly expensive…and inaccessible. It makes sense if we take into account if we see who buys in the region. What has happened? That the Notarial College of Valencia wanted to accompany the presentation of its new statistical portal (a tool valid for the entire country) of a series of data on the residential market in the region. Among all of them there are three especially interesting ones that are connected to each other. The first is the gradual rise in housing prices, the second is the negligible weight that young people have in the buying and selling market and the third is the boom in donations from parents to children, both of houses themselves and of sums of money. How much is donated? Increasingly, this shows that family support has become a key ‘key’ for young people to open the doors of the market and make the leap from tenants to owners. The data is clear. And they leave little room for doubt. According to Valencian referees, home donations from parents to children have doubled between 2019 and 2025: from 3,015 they have gone to 7,776. In short, they have skyrocketed 158% in five years. That’s if we’re talking about properties themselves. If we look at monetary donations, those that are based on money and that facilitate the payment of deposits or the signing of mortgage loans, the increase has been even more pronounced. How much have they increased? Those kinds of donations have almost quadrupled. If in 2019 Valencian notaries managed just under 3,000 operations in which parents gave money to their children to facilitate the purchase of a residential property, last year that figure had already climbed to almost 11,100 operations. 279% more in just five years. This boom was registered in all provinces. In Valencia it went from 1,647 to 5,370; in Alicante, from 844 to 4,012; and in Castellón from 432 to 1,712. Regarding the average amount of donations, in 2025 they exceeded 75,000 euros. Does it only occur in that region? No. In fact, the data from the General Council reflect that it is a fairly widespread trend in Spain. In 2025 the group processed more than 225,300 donations throughout the country, a data that can be analyzed from several angles. To begin with, it is the highest indicator since at least 2011 and far exceeds the 85,300 operations a decade ago. If that were not enough, it marks a clear upward trend: between 2023 and 2024 donations registered an increase of 15.2%, a drift that was consolidated with another 13% in 2025. At the end of 2025 the General Council I already warned that donations and inheritances were “consolidating themselves as instruments of access to housing”, a phenomenon that connects with an even larger trend: the Great Wealth Transfer. His statistics were again incontestable. Home donations went from 32,623 in 2017 to 54,735 in 2024. Residential property inheritances also drew a similar curve: from 335,888 they rose to 403,854. What is the reason? To answer that question we must recover the two keys that we pointed out at the beginning of the article: the increase in housing prices and how this increase has been closing the doors of real estate agencies to young people. Again according to the data managed by notaries, the cost of residential m2 (both in new and second-hand homes) has skyrocketed in the last decade in the Valencian Community. In 2025 it stood at 1,676 euros, 69.1% more than in 2013, when that same indicator reached minimum levels dragged down by the brick crisis. If we look at the specific case of Valencia, per m2 is even more expensive: 2,489 euros. In Alicante it has climbed to 1,889 and in Castellón to 1,297. How does that affect young people? More expensive prices require a greater capacity for savings and debt, something that is not always within the reach of young people. Especially if they are tenants before making the leap to owners. In 2024, a study by Infojobs concluded that Spaniards spend on average 47% of your salary gross payment of the rent for your home, which far exceeds the spending threshold recommended by experts and strangles the ability to save. With this backdrop it is explained that donations and inheritances have come to play a key role as a springboard to make the leap to owner. Who buys? The ‘photograph’ provided by the notaries is once again quite clear. In 2007, young people between 18 and 30 years old they accounted for 21.58% of home purchases in the region. Now that percentage has plummeted to 8.39%, even below the national averagewhich is around 9.6%. As a reference, foreign buyers represent 36.9% of the total, although their weight is not the same throughout the territory. In the province of Valencia it represents 21.97% of the total buyers, while in Alicante it accounts for 51%.

NASA wants to head to Mars in December 2028. To achieve this, it is going to use something: nuclear reactors

by

Virtually all major space companies They agree that the future of space exploration involves feeding ships with nuclear energy. For this reason, NASA has already set a date for its first interplanetary trip with nuclear-electric propulsion. It will be possible thanks to Space Reactor-1 (SR-1) Freedom, which will be launched in December 2028 heading to Mars. Destination: the red planet. NASA has long shown interest in carrying out this launch in 2028. Now, the company has assured that everything is going at a good pace and that, if it continues like this, the date could be closed around the last month of this year. In order to meet deadlines, technologies previously tested by NASA are being used. Some, for example, come from the Lunar Gateway Station, whose development is currently paralyzed. With these technologies, together with a new nuclear reactor system, a trio of helicopters similar to Ingenuity, baptized as Skyfall, will be taken to Mars. The classic and the new. The SR-1 actually runs on a closed Brayton system, which is very common for power. Normally, in these types of systems A combustion reaction takes place, which produces energy in the form of heat. This is used to heat a gas, which expands and drives a turbine. The result is mechanical energy that can be used, for example, to obtain electricity. Then, when the gas cools, a new cycle begins, which is why it is said to be a closed cycle. In the case of the SR-1, everything is almost identical. The only difference is that, instead of a fuel, a nuclear fission reaction is used to obtain the heat. Thus it is not necessary to transport large quantities of fuel into space. Just a chain reaction like those used in nuclear power plants. electric motors. The electricity obtained in this closed cycle is used to power electric motors in a process that is activated 48 hours after launch. Afterwards, you can stay active during the entire year of the trip to Mars. On the other hand, this same electricity can also be used for other purposes, such as communications with Earth. Also on the Moon. The main application of nuclear energy in space will be in very long-distance travel, where the ships are so far from the Sun that solar panels are no longer useful. However, it can also be useful at much shorter distances. If this trip to Mars goes well, NASA plans to be able to use these technologies at a lunar base installed in Shackleton Crater. Strategically it is a good locationbut it has the disadvantage of being continually in shadow, so solar energy cannot be used. Nuclear fission could be much more useful. 60 years of research. In reality, the SR-1 is the result of 60 years of research, with an investment of 20 billion dollars. Although it may seem like something new, there is a lot of work behind it. Still, if NASA’s projects go as planned, they will be time and money well spent.

In 2004 Madrid decided to build its own Guggenheim. Now it has a monster that not even Richard Gere wants as a Buddhist center

by

Many cities have pursued the idea that a single building could change everything, attract tourism and redefine their identity almost overnight. The obsession has a very specific origin: the impact it had the Guggenheim Museum in the economy and image of Bilbao, converted into a global case study. In 1997, its inauguration marked a before and after and fueled an urban fever that led to replicate that model in places where the context did not always accompany. A Guggenheim in the suburbs. At the beginning of the 2000s, in the midst of a real estate boom and with the Bilbao effect still resonating, Alcorcón decided to aspire to his own cultural icona complex that was to place the city on the international art map. The idea was ambitious to the point of excess: a macrocenter cwith nine interconnected buildings which included an auditorium, conservatory, conference center and even a permanent circus, all conceived as a kind of Madrid Guggenheim. The problem here was not a lack of imagination, of course, but the scale of a project designed for an economic reality that was about to disappear. A half giant. The works They started in 2007 with budgets that were already high, but soon they began to chain modifications, cost overruns and difficult decisions to justify, such as the demolition of a practically new library or the incorporation of such peculiar facilities as, attention, stables for animals. When the 2008 crisis hit squarely, the project was stopped with around 70% executed and more than 100 million of euros invested, leaving behind a huge structure, partially completed and without a clear function. What should have been a cultural emblem became an empty mass, one too big to abandon completely and too expensive to finish. The hidden cost of an impossible project. Beyond the initial investment, CREAA had profound economic consequences for the municipality. The reason? It had been financed through a public company that ended up accumulating a gigantic debt. The estimates spoke of tens of millions additional costs to complete it and several million annually just to keep it running, which turned it into a structural problem rather than an opportunity. In fact, even its design played against: a complex so integrated that turning on a single zone meant activating practically the entire system, skyrocketing costs and making any reasonable partial use unfeasible. Nobody wants the “Guggenheim” of Alcorcón. Over the years, the building became a kind of failed promise that was passed from hand to hand without finding real lace. Projects of all types and colors were considered, from an NBA campus to a sports university, passing through a large Buddhist center promoted by Richard Gerebut none came to fruition and most of those interested declined the opportunity. Even more recent initiatives, such as the creation of a great audiovisual hubhave ended up running aground when faced with the real costs of adapting facilities designed for a completely different context. The idea that that complex could become an international benchmark has been diluted with each failed attempt. From cultural icon to symbol of excess. Over time, CREAA has gone from being an emblematic project to becoming another example of that appellant excessive planning in Spain, a construction that aspired to change the identity of a city, but ended up conditioning its public narrative. The image of that large iron and concrete structure, partially finished and unused for years, has weighed more than any original intention, fueling the debate about the limits of public spending on large-scale cultural projects. A partial ending to an unfinished story. However, in recent years, some spaces have begun to find usefulnesssuch as the installation of a state victim care center or the partial reopening of certain areas, but the whole is still far from fulfilling the vision with which it was conceived. More than a decade later, the complex begins to reactivate in a fragmented way, adapting to much more pragmatic needs than those from which it was born. The result, as in other phantom “moles” of the Peninsula, is a persistent reminder of a time when it was thought that it was enough to build big to transform a city, without foreseeing that the real challenge would really come later.

China already knows how to keep a fleet of drones in the air indefinitely. The problem is that there are too many problems

by

Wireless charging in everyday devices It is a resource that provides comfort. In other areas, wireless and remote charging implies a much more powerful advantage: supremacy over a rival. That is precisely what China is testing, how to maintain a drone fleet flying almost indefinitely thanks to a microwave charge injected from a ground system. And they are not the only ones. In short. A few days ago, Chinese scientists from Xidian University published a peer-reviewed article in the journal Aeronautical Science & Technology in which they presented a system microwave emitter that could send energy to an array of antennas installed on the top of a drone to charge the vehicle’s battery in mid-flight. The most important thing is that it works while the ground vehicle and the drone are moving, which eliminates the need for a stationary charge that would make no sense from a strategic point of view. Image of Xidian University How it works. For the system to work, and as we read in SCMPthe researchers integrated a GPS positioning system that allowed a drone and a ground vehicle to be aligned. On the ground there is the microwave emitter and the drone has a series of antennas at the bottom that collect the energy. In tests, the system kept fixed-wing drones in the air for up to 3.1 hours at an altitude of 15 meters. The great challenge was maintaining the alignment between the drone and the ground vehicle to maximize the load, but once the obstacle with the GPS system was overcome, the drone can stay in the air depending only on the vehicle’s fuel. On the other hand, we are approaching it from the point of view of indefinite autonomy, but such a system would also allow drones to have less battery (which, in the end, adds weight) and have more carrying capacity. The BIG asterisk. Defense analysts liken it to a “land-based aircraft carrier” in which an armored vehicle on the ground is both the command and power node, monitoring, charging and providing logistical support to the drones in a manner similar to that of a aircraft carrier It is the lifeline of manned fighters. However, the system has a huge problem: it is extremely inefficient. The Xidian team estimates that the efficiency of the microwave ‘cannon’ is between 3 and 5%. It’s… ridiculous, which means that the vast majority of the energy emitted is simply wasted. Why not a laser? It’s the big question. A laser system is more precise and has a longer range, which opens the doors to other types of missions. However, being a beam of light and not directly the energy that we launch, the laser is very sensitive to interference such as fog and dust. Also, think of the laser as a precision rifle and the microwave as a shotgun: any turbulence or bump in the road would affect the beam, but microwave energy has a wider range of action. China is not alone. Chinese analysts point out that it is a promising concept, but also something that is very far from being able to be applied to satisfy an immediate operational need. What it is, is one more step to find that way to get those drones that are appearing to be a very valuable element on the battlefield, as the wars in Ukraine and Iran, unfortunately, are demonstrating. The advance is important because Xidian has time working in the theoretical framework of the technology, but it is now that they have carried out a successful field test. Now, they are not alone, since the American agency DARPA is experimenting with radio frequency and laser to charge drones remotely, and in Germany, Rheinmetall is also developing wireless charging platforms for unmanned ground vehicles, although in this case, the drones are perched on a platform.

studies a huge submarine cable with distant Ireland to stop being an energy island

by

Spain may have emerged as one of the EU states that more and better have understood and adopted the energy transition towards renewables, but there is an unquestionable geographical reality: The Iberian Peninsula is an energy island which has a problem called France. A bottleneck that prevents Spain from exporting its enormous surplus of solar energy, so the European Commission wants to correct it with ambitious connection goals for 2030. How? Looking at the sea that surrounds the peninsula in search of partners “to lend a helping hand” to solve this limitation: across the Mediterranean with two gigantic connections to Italy and also towards the Atlantic, with a cable between Spain and Ireland. The future cable between Spain and Ireland. The planned route would link the northern coast of Spain, specifically Asturias, with the southern coast of Ireland, with an estimated length of between 1,000 and 1,100 kilometers, as collects The Energy Newspaper. Although there is no defined route yet, the infrastructure will have to navigate considerable depths in the Bay of Biscay and the Celtic Sea. Go ahead that the agreement signed between Spain and Ireland It is a Memorandum of Understanding to study the feasibility of an underwater electricity cable within the framework of the WindEurope 2026 congress held in Madrid signed by the Spanish vice president Sara Aagesen and the Irish minister Darragh O’Brien. Why is it important. Because both Spain and Ireland share a structural problem: they are one of the least interconnected electricity markets in Europe and are classified as “energy islands” by the EU, which limits their ability to export renewable surpluses and reinforce their security of supply (friendly reminder: the blackout). From the point of view of energy security, more interconnection means less dependence on imported fossil fuels and more resilience in the face of shortages. This cable would diversify Spanish export routes, a detailed priority objective in REE Electrical Planning. The energy logic of the project rests on the complementarity of renewable resources: Spain would export solar surpluses and Ireland would provide electricity generated in its offshore wind farms. Both technologies have generation profiles decoupled in time, so the exchange is technically valuable to stabilize both electrical networks: when the sun shines in Spain, it can power Dublin, when Atlantic storms sweep the north, its wind turbines can sustain Spanish industry. Context. Spain currently has barely 3,000 MW of interconnection capacity, which represents a ratio of 2%, according to REE dataon its installed mix of approximately 150 GW. That is to say, it fails to meet the minimum target of 10% set by the EU for 2020 and has to work a miracle to reach the 15% planned for 2030. This chronic deficit limits the capacity of the Spanish system to export the growing surpluses of wind and solar energy. The project arises at a time of maximum urgency for energy independence after the gas crisis. Recent war conflicts have led the EU to accelerate the processing of large electrical interconnections between European markets as a tool for collective energy security in search of self-sufficiency with its own resources. Initiatives like the plan REPowerEU They have these cross-border interconnections as one of the levers with absolute priority. Map of transmission and storage projects. ENTSO-E Main connections in Spain. A brief summary of the very few electrical connections of the Spanish state with other EU states: Existing: Spain–France (Pyrenean land interconnection), with a current capacity of approximately 3,000 MW through the Pyrenees and Spain – Portugal, through various bidirectional land high voltage lines that make up the Iberian market. Under construction or approved: the submarine cable of the Bay of Bizkaia between Spain and France, scheduled to enter service in 2028, will add 2,000 MW of additional capacity with France. The wire Fontefríabetween Portugal and Galicia, will provide about 1,000 MW of exchange. Projected (under study or preliminary phase): Apollo Link between Spain and Italy, of 2000 MW and entering service in 2032. Iberia Link between Spain and Italy of 1,200 MW. Trans-Pyrenean land connection through Navarra and Aragon, blocked by the French government. How are they going to do it?. Technically, the project would be executed using a high-voltage direct current (HVDC) cable, the standard technology for long-distance underwater interconnections, due to its lower energy loss in transportation compared to alternating current. There are direct and operational precedents of a similar scale, such as the recent Celtic Interconnector between Ireland and France. After signing the Memorandum of Understanding to study the viability of an underwater electricity cable that links both states, the project must be technically and economically evaluated jointly by Red Eléctrica and EirGrid, the operators of both states. They will then present it to the European authorities for possible inclusion in the list of Projects of Common Interest (PCI), which would give it access to European funding and accelerated administrative procedures. ENTSO-Ethe association of European network operators, publishes every two years the Ten-Year Network Development Planthe technical reference framework to prioritize and evaluate this type of projects. Yes, but. The project is in its earliest phase, which means that it has everything ahead of it and a submarine cable is a major technical and economic infrastructure. A cable of more than 1,000 kilometers in length implies an estimated investment that would exceed 2,000-3,000 million euros, a construction period of several years once approved and logistical challenges in North Atlantic waters. Furthermore, the route through Asturias would require reinforcing internal transport networks to cross the Cantabrian Mountains to connect with the large solar generation centers in the interior of the peninsula.

We’ve found molecules linked to life on Mars, but let’s not break out the champagne just yet

by

The Curiosity rover has carried out a chemical experiment on Mars that has never been done on another planet. Thanks to it, it has detected organic molecules that until now had gone unnoticed by us. Does that mean that there is or was life on the red planet? It could be, but it could also be due to many other things. Although we always read this type of news with joy and it gives a lot of sensational headlines, we must analyze the results with the optimism of what they mean for science, but the caution of what they imply in the search for extraterrestrial life. Chemical advances millions of kilometers away. Curiosity’s SAM instrument has carried out an experiment known as thermochymolysis. In it, a reagent called tetramethylammonium hydroxide (TMAH) is used. to break large molecules into small fragments. Thanks to this, organic molecules can be detected that are invisible with other methods. Among other organic molecules, some rich in nitrogen have been found, which could be related to DNA synthesis. The discovery of benzothiophene, present in some biological processes, also stands out. Let’s not go up. The authors of the study that has just been published thanks to the Curiosity rover they call for caution with its results. They insist that all the molecules found could come from abiotic processes or have reached Mars from other points in space. For example, benzothiophene could be formed by geological or hydrothermal processes. In addition, its presence has been found in meteorites and asteroids on Earth. It could also have reached Mars like this. Only two tries. Regardless of whether the findings have to do with life or not, this study is very relevant for two reasons. On the one hand, because it was the first time that this experiment could be carried out outside of Earth. And, secondly, because Curiosity I only had two tries to do it, but he made good use of them. This is because TMAH was in the exact dose needed, inside two sealed capsules. If the first failed, the second could be tried. If this one did it too, goodbye experiment. That it was done without problems has been a great achievement. This is an annotated close-up of three holes that NASA’s Curiosity drilled into Martian rock at a location nicknamed “Mary Anning” in October 2020. The sample where the rover found a large number of organic molecules came from “Mary Anning 3.” (A nearby site nicknamed “Mary Anning 2” was left unused.) NASA/JPL-Caltech/MSSS A very old search. Science has been obsessed with the search for life on Mars since in the 17th century some scientists detected with their telescopes what appeared to be the presence of water ice. Already in the 21st century, advances in space exploration allowed orbiters and rovers to be sent to Mars in order to analyze possible signs of life. Some were found. For example, in 2018 methane was detected in its atmosphere. This could be the result of microbial activity, but also geological processes. In 2020 Curiosity found carbon isotopes and later, in 2025, the longest carbon chain found to date. It is true that carbon is necessary for life, but it can also be related to many abiotic processes. In none of these cases has it been possible to demonstrate that there is life behind it, so we still cannot prove that there is life on Mars. Maybe we lack tools. In 2023 a study was carried out in the Atacama Desert to analyze the tools normally used to search for life on Mars. This desert is one of the largest Martian analogues we have on Earth. It has many similar characteristics to those of the red planet; but, of course, it also has more than proven life. However, when analyzed with Mars exploration tools, many of the traces of life that should have appeared were not detected. This shows that perhaps we haven’t found life on Mars yet because we don’t have the right tools. Although there may also simply not be any. The future. Curiosity has carried out this experiment directly on Mars. However, the ideal would be to send rock samples to Earth, to use other more complex analysis technologies there. Another rover, Perseverance, is prepared to collect samples and send them to Earth. In fact, it was scheduled to do so. However, the mission was canceled by the United States Congress last January. Meanwhile, other space agencies aim to replicate the TMAH experiments. This is the case of the ExoMars mission of the European Space Agencywhose Rosalind Franklin rover will also travel with this reagent to carry out thermochemolysis. We’ll have to wait to see what he discovers. Whatever it is, as always, we will read it with caution. Image | POT In Xataka | ExoMars, this is Europe’s most ambitious mission to Mars

This is the silent crisis of the chip of the future

by

While the world has its eyes on the race for traditional silicon and artificial intelligence, a silent crisis is brewing in the global technological bowels. The United States and Europe are investing billions to recover the sovereignty of microchips, but they have ignored a material that could put the future of robotics, defense and energy in check: gallium. Western blindness to an absolute monopoly. Gallium is not as high-profile as lithium, it is not even technically a “rare earth”—as the specialized publication China Talk—but it is of irreplaceable critical importance. While the US administration strives to shield its supply chains, Beijing has been moving its chips around the board with impeccable stealth. The data is overwhelming. China currently controls 99% of the global primary production of galliumwhile the United States stopped producing it almost four decades ago. The great particularity of this material, according to Geopolitical Monitoris that it is not extracted directly from a mine, but is a byproduct of the processing of aluminum and zinc. This makes it deeply vulnerable: its production cannot magically increase no matter how much demand rises. This dependency is not a mere theory. China has already started using this domain as a geopolitical weaponimposing export restrictions in 2023 and escalating to a complete ban on shipments to the United States at the end of 2024. From mastering the mineral to conquering the factory. The Asian giant’s strategy was not the result of chance. As pointed out China Talksince the early 2000s, China forced its aluminum producers to extract gallium, achieving self-sufficiency and global control of the raw mineral (what is known in the industry as a market upstream). But the real drama for the West is happening right now in the final products (downstream). China has given birth to the “TSMC of GaN”: Innoscience. This Suzhou-based company has burst the global market for Gallium Nitride (GaN) power semiconductors, sinking its American rivals – such as Navitas or EPC – by offering prices up to 50% lower. Such a collapse in prices is not magic. The secret lies in a lethal combination of state financial muscle and technical audacity. As revealed China Talkin its early years Innoscience It operated with negative gross margins of 266%, supported by more than $350 million in government funds. They were willing to lose money to gain the world. Added to this is its industrial business model. While Western companies are fabless (they design the chip but pay third-party factories, such as the Taiwanese TSMC, to assemble it), Innoscience manufactures its own chips. They were the first to mass produce 200mm wafers, allowing them to get 80% more components out at a fraction of the cost. Against this backdrop, the pattern that is drawn is chilling and mirrors that of the solar panel industry: European giants such as STMicroelectronics They have ended up surrendering to the superiority of Innoscience, injecting $50 million into the Chinese firm in exchange for access to its factories. Goodbye to traditional silicon. To understand the seriousness of the issue, you have to understand why silicon is no longer enough. As they point out from AZOM, Silicon is reaching its physical limits. Gallium Nitride (GaN), on the other hand, is a “broadband” semiconductor (wide bandgap). Compared to 1.1 eV for silicon, GaN has a bandgap of 3.4 eV, allowing it to operate at much higher voltages and temperatures without melting. Translated into simpler words: GaN provides greater energy efficiencythe devices do not heat up and allow the size of the components to be drastically reduced. That’s why our mobile phone chargers are now smaller but charge the battery in minutes. Beyond a phone. Gallium Nitride is the master pillar of critical technologies: AI data centers: These chips reduce energy losses by up to 30%, something vital in the face of the devouring electrical appetite of Artificial Intelligence. Electric vehicles: They are key for on-board chargers and converters, radically improving their autonomy. Defense and Military: Advanced radars, missile systems, electronic warfare and the 5G antennas that connect us all depend on GaN. A future dictated from Suzhou. The market is about to explode. From Geopolitical Monitor projects that the sector GaN semiconductor devices It will go from generating 3.06 billion dollars in 2024 to almost 12.5 billion dollars in 2030. And the lion’s slice seems to have a Chinese name. It is a fatal mistake to think that Innoscience He wins only because he is cheap thanks to the million-dollar subsidies from his government. As clarified China Talkthe company innovates at the highest level, designing chips across the entire voltage spectrum (from 15V to 1200V). Its quality is such that it has become the only Chinese partner of American giants like NVIDIA and Google to design the 800-volt power architectures that will power the “AI factories” of the future. The forecast is dark, but there is an ace up the sleeve. If the West does not react, Innoscience will go from having a dominant position to an absolute monopoly. If a new trade war breaks out, car, robot and data center manufacturers in the US and Europe will have to ask permission from a single Chinese company to be able to turn on their machines. Despite the pessimism, the battle is not entirely lost. Western companies and governments are testing various containment strategies: The judicial trench: Companies like EPC and Infineon They have sued Innoscience in the US for patent infringement, achieving some import restrictions. However, this is just a patch; The bans usually apply to loose chips, but not to final products assembled in China, and the Asians can redesign their models to bypass the ban. The technological leap (300 mm): The great hope is in changing the rules of the game. Texas Instruments (USA) and Infineon (Germany) are leading the move to larger, 300mm GaN wafers. They have the advantage that the highly specialized machinery to manufacture them is in German and American hands, heavily protected by export controls. Furthermore, at the basic … Read more

In 2023, an exclusive Rolex was stolen from Keanu Reeves’ house in LA. A year later they found him in the most unexpected place: Chile

by

In September, Rolex, the luxury when it comes to watches, filed a patent application that gave an idea of ​​the house’s problems with thefts and counterfeits of its most legendary models: they sought use NFT chips and certificates of authenticity based on blockchain to identify the models. The story (with a happy ending) of Keanu Reeve’s watches has surely only reinforced that idea. John Wick’s watch. The story begins several years ago, during the filming of the film ‘John Wick 4’ that the actor played. At the end of filming, Reeves pays tribute to himself with an exclusive Rolex Submariner valued at $9,000one with the engraved words “2021, JW4, thank you, The John Wick Five” next to the actor’s name. In December 2023, someone entered the artist’s house in Hollywood Hills (Los Angeles) taking several high-value jewelry, including the exclusive model from the Swiss luxury house. Enter Keanu’s house. Curiously, It wasn’t the first time it happened.. In fact, in 2014 the home was broken into. up to two times in three days. The first time, Reeves confronted an intruder in his library, the second, the cleaning staff found an intruder in his pool. But there is more. Early last year, Reeves requested a temporary restraining order against a man who allegedly trespassed on the actor’s property at least six times between November 2022 and January 2023. In one case, the alleged stalker left a backpack containing a DNA testing kit, one he intended to use on Reeves to prove they were related in some way, according to the order request. An unexpected find in Santiago. The news broke in December 2024 in the city of Santiago, where Chilean police recovered three watches belonging to the actorincluding the Rolex Submariner from the action movie and two other models described by authorities as “valuable.” Apparently, during a series of raids on four homes, Chilean authorities seized high-value jewelry and watches, including those three models that belonged to Reeves. According to CNN reportslocal authorities collaborated with US officials to establish the link between the watches and the robbery at the actor’s residence. As a result, a 21-year-old man is under arrest. Cinematic irony. The media has not stopped repeating a curiosity these days: the parallelism with the plot of the saga itself ‘John Wick‘, where Reeves’ character begins his story of revenge after a robbery (and the death of his dog) at his home. Outside of this trivial detail, the famous actor does not seem clear about returning to the role in future installments of the saga. The reason? Mainly age. Although his heart says he wants to do it, Keanu Reeves he joked shortly after in an interview that his knees might not be ready for another film due to the physical demands of the character. The symbolism of John Wick’s Rolex. As for the recovered watch and beyond its economic value, the Submariner represents Reeves’ appreciation for his team, known in the industry for giving away personalized watches as gestures of gratitude after finishing filming. In this case, the actor had kept one model and had given the rest to the doubles who played him in the film. Submariner, luxury on the wrist. The Rolex model is an icon of watchmaking and the first diving watch reference Truly functional. Launched in 1953 and designed specifically for divers, it became a symbol of innovation for its water resistance up to 100 meters (later extended to 300 meters) and its durability in extreme conditions. Its timeless design, with a unidirectional rotating bezel to measure immersion time and its legibility underwater, has established it as a standard in both the professional and fashion fields. In fact, before Keanu Reeves, the model He has been associated with many other historical and cultural figuresfrom ‘James Bond’ to marine explorers and other celebrities, a symbol of technical excellence and style that maintain it as one of the most recognized and desired watches in the world.

High-speed train coverage in Europe, in a revealing map

by

Japan may already have carriages with noise cancellation, windows with 5G and his bullet train is a veteran and that China has the most futuristic trains and supersonic, but the network European high speed railway It represents one of the most advanced transportation infrastructures in the world. This system has transformed the continent’s mobility since 1981, when France laid the foundation inaugurating its first TGV line. Today, high-speed trains have a route of approximately 65,000 kilometers, transporting 2.5 billion passengers a year with 4,900 trains, according to data from the International Union of Railways (UIC). But since a picture is worth a thousand words, it is better to see them displayed on the map of the old continent. This map of Europe’s high-speed rail network is the fruit of the collaborative effort of several Wikimedia Commons users, who update it annually with new projects from from official UIC data. Of course, macro data is one thing and the reality of this train grid is another, because within the network there are huge differences between some areas and others. Even within the “high speed” classification itself. The map uses a color code based on the maximum operating speed allowed on each section, with black for non-high-speed lines: The lines in pink represent the maximum high speed category, 310-320 km/h. State-of-the-art infrastructure with wide curvature radii, controlled slopes and advanced signage. The red lines are the European speed standard: 270 to 300 km/h. The yellow and orange lines are for those trains that reach 200 to 260 km/h, generally on sections with topographical limitations. The dotted green lines correspond to roads under construction or updating, essential to glimpse the future evolution of the network. Europe by high speed train Broadly speaking, Western Europe concentrates the highest density of this infrastructure, especially highlighting the axis that connects Spain, France, Germany and Benelux, while Eastern Europe maintains significantly less development. High-speed lines operational in Europe in December 2025. Wikimedia Because as we move east on the map, the colored lines disappear and space out, evidencing a dramatic infrastructural gap: Poland, the Czech Republic, Hungary, Romania and the Baltic countries practically lack operational high-speed infrastructure, depending on slow conventional lines that severely limit the competitiveness of the railway. And boy does it show: according to the Romanian Ministry of Transportthe Budapest-Bucharest high-speed project with a 590-kilometer line would reduce the current trip from more than 11 hours to approximately 3.5 hours. The project dates back to September 2024 and has an estimated budget of 17 billion euros. With 3,974 kilometers in service (September 2024 data) Spain holds a title: is the high-speed rail network largest in Europe and the second in the whole world, only surpassed by China. And as you can see on the map, it continues to grow. From a technical point of view and as is usual in the state, it has a radial model focused on Madrid. His constructive efficiency is remarkable: Spain has developed the second high-speed network in the world with one of the lowest construction costs per kilometer compared to the rest of the countries with this mode of transport and the lowest among the countries of the European Union. Among the most notable connections is the Eurostar, which connects Paris and London in approximately 2 hours and 16 minutes through the Channel Tunnel. It may not have as much fanfare as crossing a sea, but the Figueres-Perpignan line constitutes an essential 44.4 km link that connects the Spanish railway network with the French network and the rest of the European states, with a double-track section in UIC gauge. The main bottlenecks They are concentrated in mountainous border crossings and pending connections between national networks. Between Austria and Italy, the Brenner Base Tunnel is under construction to improve the Berlin-Palermo railway axis, connecting northern and southern Europe through the Alps. The Pyrenees are another critical point: although there is a Figueres-Perpignan connection, at the border crossing there is a single platform to concentrate everything. From an engineering point of view, the fundamental problem is the saturation of infrastructures that absorb mixed traffic of goods and people. In any case and although the EU since 2000 has invested large sums in high-speed railway infrastructure, faces a heterogeneous and fragmented scene insofar as it cannot force member states to build lines, which, together with the diversity of signaling systems, electrification and national technical standards, constitutes the true structural bottleneck of the European high-speed network.

How the Black Death caused Europe to become obsessed with the act of sneezing for centuries

by

Hebrew tradition tells that, just before biting the apple, Adam sneezed. At that moment it seems that he didn’t care much, but after the incident with the fifth piece of fruit a day he ended up interpreting it as “a sign of evil and a harbinger of death.” The noise stayed there, of course, and when the very old Jacob was worried about not getting to see his son, he begged God to change the natural order of things lest a bad sneeze take him to the other neighborhood. That’s where it comes from (collected or perhaps invented anew by medieval tradition) that we desire “health” in Spain, “saúde” in Portugal or “Gesundheit” in Germany to someone who has just sneezed. As if to ward off bad omens; that life is not enough to play with dice. However, because it is common, I still find it surprising how much a simple sneeze has come to mean. Aristotle, explains García-Morenowas convinced that, compared to flatus or belching, the sneeze was the only one that had a ‘sacred nature’ because it came “from the main and deepest and most divine of the organs, the one that contains the spirit.” Hippocrates, on the other hand, although he did not decide on the goodness or badness of sneezing, he did describe the principle of reciprocal inhibition by pointing out that sneezing was, mind you, the best remedy for hiccups. As I said, the history of sneezing in the West cannot be understood in all its complexity without the Black Death. It was then that the “health” of the Jewish tradition or the “Jesus” of the Christian tradition became popular again as a way of wishing that this ‘achís’ was not the doorway of the damned plague. The “God bless you” that still resonates in English formulas (‘bless you’) comes, it seems, from one of the many plagues that struck medieval papal Rome. In contrast, in many other places, sneezing was considered a good thing. Fantastic. Traditional Hindu medicine used to provoke it as a way to balance internal humors and treat illnesses while the more archaic African medicine used it protopsychiatrically as a way to cure mental illness (supposedly caused by the existence of worms in the brain). To finish, to finish at some point, the Aztecs used it for headaches. What is a sneeze really? In reality, a sneeze is something very simple. It is a reflex actionsudden and compulsive, whose purpose is to expel large amounts of air through the nose and (sometimes) also through the mouth. It is, therefore, a physiological reflex that the respiratory system uses defensively. Therefore, it usually occurs when certain foreign particles irritate the nasal mucosa. And yes, I have used “usual” with all the intention in the world. As it seemsand these are average estimates, before each sneeze we inhale about two and a half liters of air. That is the first phase, the inhalation phase. At that moment, the abdominal muscles tense the diaphragm to increase the pressure in the lungs and force the air to come out through the nose at dizzying speed: between 70 and 130 kilometers per hour. The saliva that is usually expelled when sneezing can cover an area of ​​up to 8 square meters. And that is precisely what makes a sneeze one of the worst vectors of disease spread in the world. However, sneezing is most popular precisely when it is most harmless: in spring, summer or autumn. When it is caused by ‘allergic rhinitis’. A classic, indeed. This type of rhinitis, caused by pollen from trees, weeds and grasses, becomes the great recurring character in the lives of practically a third of the population. It is unbearable, unbearable, a cross. But, still, there are worse sneezes. Between 18 and 25% of the population sneezes suddenly when exposed to bright light. This is what is known as ‘photic sneeze‘and it’s an old acquaintance (and a cause of disability) of aviation pilots. Apparently it is hereditary and is produced by an anatomical proximity between the second cranial nerve (the ocular, responsible for carrying visual information to the brain) and the fifth (the trigeminal, which seems to be responsible for sneezing). When there is very bright light, excitation of the optic nerve can cause excitation of the trigeminal nerve. This signal is interpreted as irritation of the mucous membranes and releases a beautiful, annoying and enormous sneeze. Something similar (although this time linked to the medulla oblongata) may be behind people with a natural tendency to sneeze after eating, when they see something pleasant, or even during orgasm. It is already a bad idea, although used well (and even Aristotle would agree with this) it can be seen as a “wonderful” way to improve communication in the bedroom.
