Testing the first light bulb in 1879, Edison came across a material that would be discovered 125 years later: the prodigious graphene.

Edison has been one of the most prolific inventors of history. In fact, while he was looking for a way to make the light bulb, he carried out an exhaustive materials science experiment: tried more than 6,000 organic materials before decant by the carbonized bamboo filament. eye to the old patent no. 223,898 because it has all the necessary ingredients for the recipe. Tremendous Edison spoiler. He had, without knowing it, set up a primitive nanotechnological reactor to obtain graphene. That same graphene on which Philip Russell Wallace would theorize 20 years after the inventor’s death and 125 years before Konstantin Novoselov and Andre Geim won the 2010 Nobel Prize in Physics for isolating it with the duct tape method. Or so he has discovered a recent study from Rice University. The prodigious graphene. Graphene is an allotrope of carbon that has a two-dimensional structure of atoms woven into a hexagonal network. Beyond this curiosity, graphene is an amazing material: it is 200 times stronger than steel but much lighter (airbrush, even lighter than air). It conducts electricity and heat better than any known metal. If we also take into account that it is almost transparent and very flexible, we have a prodigious material for technology. Without going any further, for semiconductors. It could also be used to improve roads or for responsive robotic tissues. And there’s a trick: when its layers are somewhat disordered and not stuck together like a block, they are much easier to separate. This is what Edison achieved unintentionally. Edison’s recipe. He turbostratic graphene can be produced by applying a voltage to a carbon-based material until it reaches a temperature of 2,000 to 3,000 °C, known as Joule heating instant. But what Edison had in his power was to light one of his newly patented light bulbs. Unlike the current ones, theirs had carbon-based filaments, more specifically bamboo. When you flipped the switch, the filament heated up and produced… light and maybe graphene. Account Lucas Eddy, the paper’s lead author, was looking for ways to mass-produce graphene with accessible, affordable materials and tried everything from arc welders to trees that had been struck by lightning. Then he remembered the light bulb. Edison’s patent It was a magnificent scheme to reproduce the experiment. Of course, it was difficult for him to find Edison-style light bulbs with carbon filaments and not tugsten. Then he only had to apply power to 110 volts and turn on the switch for 20 seconds. If you go too far, graphite can form instead of graphene. Why is it important. To begin with, because until now we thought that to obtain this prodigious material we had to resort to 21st century technology, but no: there were conditions to do so in the 19th century. On the other hand, it validates Joule heating as an efficient and scalable way to generate high-quality graphene from cheap carbon sources. And why not, because it opens the doors to reviewing other scientific experiments in history: who knows if other nanomaterials have not been synthesized by chance? under the microscope. Using the lens of an optical microscope, the research team was able to see that the carbon filament had gone from dark gray to a shiny silver. A visual change that predicted the suspicions that I ended up certifying with the Raman spectroscopywhich uses lasers to identify substances through their atoms with high precision: it was turbostratic graphene. While Edison experimented to create a light bulb for everyday use he was able to produce the wonderful material of the future (of today’s future). Obviously there is no way to know for sure what happened in their Menlo Park laboratories because even if the original light bulb were available for analysis, any graphene produced would probably have converted to graphite within a few hours.

Valve has been charging a 30% commission on Steam for twenty years. Now it’s your turn to explain why before a judge.

Valve will have to defend its business model before the British courts after the Competition Appeal Court of London authorized on January 26 a class action lawsuit that could cost £656 million, about $900 million. The accusation: the American company abuses its dominant position in the PC games market with commercial practices that keep prices artificially high and limit competition between digital distributors. The demand. Vicki Shotbolt, activist specializing in digital rights and CEO of Parent Zonefiled the legal action in June 2024. It represents approximately 14 million British users who have purchased video games or additional content through Steam since 2018. The case is based on three arguments: first, it questions the 30% commission that Valve charges on each transaction on Steam. The prosecution considers this fee excessive and maintains that it has a direct impact on the final price. The second argument attacks “price parity obligations”: contractual restrictions that would prevent studios and distributors from offering their titles at more competitive prices on other platforms. Valve would have intervened in specific cases when detecting more aggressive discounts outside of Steam. The third point points out a retention mechanism: whoever purchases a base game on Steam must purchase all subsequent downloadable content exclusively on that platform. Other cases. The British case is not an isolated episode. In the United States, independent studios Wolfire Games and Dark Catt Studios filed antitrust lawsuits against Valve in 2021. They were initially dismissed, but the plaintiffs reformulated their arguments and resubmitted them in 2022. A court ordered the two cases to be merged. Since then, any developer, publisher or individual who has paid commissions to Valve on sales since January 28, 2017 can join. David Rosen, founder of Wolfire Games, explained which took legal action after Valve’s direct intervention when it tried to offer lower prices on other platforms. In August 2024, four players from California, Florida, and Missouri filed a separate lawsuit accusing Steam of “strangling competition with blatantly anti-competitive pricing restrictions.” Antitrust. The lawsuits against Valve are part of a broader pattern of antitrust litigation. The most relevant precedent is the confrontation between Epic Games and Apple: the developer of ‘Fortnite’ implemented an alternative payment system that avoided the 30% commission of the App Store. Apple won most points in the litigation, but had problems in certain states such as California. The case against Google had a more forceful outcome: Epic demonstrated that the company had illegally monopolized the Android ecosystem, which will force Google to allow competing app stores on its devices until November 2027. Antitrust. The lawsuits against Valve fit into a broader pattern of antitrust litigation. The most relevant precedent is the confrontation between Epic Games and Apple: The developer of ‘Fortnite’ implemented an alternative payment system that avoided the 30% commission from the App Store. In May 2025Fortnite returned to the Apple store. The case against Google had a stronger outcome: Epic managed to prove that the company had illegally monopolized the Android ecosystem, which will force Google to allow competing app stores on its devices until November 2027. The magnitude of Valve. Steam hosted more than 19,000 video games during 2025, generating total revenues of $11.7 billion. The income that Valve obtains exclusively from its commissions on sales increased from 1.1 billion dollars in 2015 to an estimated 3.2 billion in 2024, tripling in less than a decade. Additionally, Valve produces approximately $50 million in revenue per employee, an exceptional figure even in the technology sector. The London court has not yet set a date for the trial, which will determine whether these practices constitute abuse of a dominant position. If the lawsuit is successful, the affected British users could receive compensation for the extra costs that, according to the accusation, they have been paying for years.

Sanderson finally signs the Cosmere adaptations after years of fighting, and Apple gives him more control than George RR Martin has

Brandon Sanderson has closed an unprecedented agreement with Apple TV to adapt the literary universe of Cosmere. The platform will develop films based on the ‘Mistborn’ saga and a series of ‘The Storm File’, the author’s two main franchises. The pact gives Sanderson a level of creative control higher than even that enjoyed by JK Rowling or George RR Martin with their respective adaptations: he will be the architect of the universe, he will produce, he will be consulted and he will have the power of approval over creative decisions. Several attempts. The announcement comes after years of deals that did not come together. In 2016, DMG Entertainment acquired the rights to the Cosmere for $270 million for three films, but the project never moved forward. own Sanderson recognized in December 2024, in your annual updatebeing “back at square one” after the collapse of negotiations for a film adaptation of ‘Mistborn’ that had reached very advanced stages of development. The project had taken five years of work, had a finished script and linked actors whose identities he could not reveal. Sanderson later detailed on Reddit that the plan contemplated a hybrid model: a first big-budget film followed by a television season covering the period between books one and two of the original trilogy. A second film would adapt the second book, followed by another transitional season. The main actors would have signed contracts for both film and television. An unusual success. The new agreement with Apple represents the culmination of the publishing phenomenon led by Sanderson: his books have sold more than 50 million copies worldwide, a figure that includes both his solo works and his contributions to ‘The Wheel of Time’ by Robert Jordan, which he completed after his death in 2007. In 2022 he established the record for Most successful literary Kickstarter in history by raising 41.7 million to self-publish four secret novels written during the pandemic. But what is the Cosmere? The Cosmere is a shared universe that interconnects multiple fantasy sagas through a common cosmology and interlocking systems of magic. The model resembles Isaac Asimov’s approach with his universe of robots and foundations, although Sanderson planned the connections from the beginning to avoid the need to reconcile items later. The Cosmere encompasses different planets with distinct civilizations, histories and magical systems but based on a shared mythology: the being Adonalsium, whose power fragmented into sixteen shards distributed throughout the cosmos. The agreement. Apple closed the deal after a competitive process in which Sanderson met with most of the top studio executives in Hollywood. In this way, the company is left with a fictional universe that has similarities with another franchise it also owns, ‘Foundation’ (and, in part, with ‘Silo’), which allows it to compete in the field of fantasy and science fiction adaptations with Amazon (The Lord of the Rings: The Rings of Power, The Wheel of Time), HBO (Game of Thrones) and Netflix (The Witcher). It is not the first time that Apple has reached agreements with prestigious creators, such as Alfonso Cuarón (‘Disclaimer’) or Martin Scorsese (‘The Moon Killers’), but none had been given as much creative control as Sanderson. The challenges of the Cosmere. The technical and narrative complexity of the Cosmere poses notable obstacles. For example, magic systems: Allomancy in ‘Mistborn’ allows users to “burn” ingested metals to obtain supernatural abilities differentiated according to each metal. Sanderson expressed on Reddit his concern about a possible oversimplification that denaturalizes these systems, designed with coherent internal rules that structure entire plots. The length of the works is another problem: the books often easily exceed a thousand pages. For example, the five Stormlight Archive books add up to nearly two and a half million words, and Sanderson plans ten volumes in total. The expectation. The announcement made by the author on Reddit generated thousands of comments analyzing the implications of the level of creative control guaranteed to the author. The closest precedent to this model could be Peter Jackson with ‘The Lord of the Rings’, although in that case the author of the original work was absent. Meanwhile, Sanderson asks for patience: film development requires years of prior work, usually between two and three, before reaching the production phase. What is clear is that although Sanderson’s presence provides guarantees and Apple is potentially a great option for adaptation, the process is not going to be easy.

The Zapotecs have been fascinating archaeologists for years. A 1,400-year-old tomb in Mexico has revealed how they viewed death

“It is the most relevant archaeological discovery of the last decade in Mexico.” Who is speaking It is Claudia Sheinbaum, president of the country, and although it is not unusual for authorities to resort to superlatives when presenting historical findings, in this case the enthusiasm of the Mexican leader seems more than justified. After all, it is not every day that we find jewels like the one that the INAH just located in the Central Valleys of Oaxaca: a tomb from 1,400 years ago that promises to reveal new secrets about one of the most fascinating pre-Hispanic cultures of pre-Hispanic Mesoamerica. Who is it? The Zapotecs. What has happened? That Mexico has shown (one more time) that still hides first-class archaeological treasures. Your Government has just announced the discovery of a 14-century-old tomb decorated with exceptional paintings and sculptures in the south of the country, in San Pablo HuitzoOaxaca. There the National Institute of Anthropology and History of Mexico (INAH) has documented a Zapotec tomb dated around the year 600 AD, a large and ornate mausoleum that stands out for its good level of conservation. Its structure and sculptures are so well preserved, in fact, that experts hope they will shed new light on the civilization that erected it. Is it so relevant? Yes. Perhaps the best proof is that the Mexican authorities have not spared congratulations and flattery when referring to the discovery, which the president herself has been in charge of presenting. “We are very proud of the most relevant archaeological discovery of the last decade in our country,” he said. claim Sheinbaum on social networks. Similar words have been used by the Secretary of Culture, Claudia Curielthat has emphasized that same idea: it is not just that the Oaxaca tomb is spacious or rich in decoration, it is that a good part of its structure has managed to remain intact for 1,400 years, so today it offers a valuable ‘historical window’ to historians dedicated to the study of the Zapotec civilization. “This is an exceptional discovery due to its level of conservation and what it shows about the Zapotec culture: its social organization, its funerary rituals and its worldview, preserved in architecture and painting.” What does the tomb show? A combination of murals and sculptures surprising. At the entrance to the antechamber we find a sculpted owl, an image that in the worldview of its pre-Hispanic creators symbolized night and death. The figure is fascinating because its beak hides another surprise: the stuccoed and painted face of a Zapotec lord. Because of this position it stands out, right at the entrance to the mausoleum, archaeologists suspect that it could be a portrait of the ancestor to whom the tomb was dedicated and to whom his descendants turned as an intercessor before the gods. Is there more? Yes. As we move forward we find a decorated lintel with a frieze made up of stone tombstones engraved with “calendrical names”. If we look towards the jambs, another surprise: the figures of a man and a woman dressed in headdresses. Once again, their position has led archaeologists to speculate on their possible role, which in this case would be that of guardians. Already inside the funerary chamber, the walls preserve parts of “an extraordinary mural painting” with ocher, white, green, red and blue colors. In them, their authors portrayed a procession of characters with bags of copal. What do we know about the tomb? Researchers will have to continue studying it to understand it better, but they already have some clues. For example, the dating: they believe that the tomb dates from the late Classic period, around the year 600. They have also come to the conclusion that its sculptures and mural evoke “symbolic representations associated with power and death.” Now it is their turn to continue deciphering its iconography and (just as important) to advance conservation efforts. INAH himself explains that its experts are working to stabilize the mural, which is in a “delicate” state after 14 long centuries exposed to changes in time and the advance of roots and insects. Who were the Zapotecs? If the tomb has generated so much expectation, it is not only because of its good general state of conservation. The tomb is also valuable because it opens a new window to the Zapotecsa pre-Hispanic civilization from Mesoamerica that called themselves Binniza (“people who come from the clouds.” As remember the Mexican Archeology platform, constitute the oldest group in the Oaxacan region and since at least 1400 BC they mainly inhabited the Central Valleys and their surroundings. Its peak was reached between the 4th and 10th centuries AD, with its settlement of Monte Albán standing out above all, one of the most relevant cities in Mesoamerica at its time. It is estimated that it hosted some 35,000 people. The region has such relevant historical and heritage value that in 1987 UNESCO declared the historic center of Oaxaca and Monte Albán as a world heritage site. In recent decades, archaeologists they had already found Zapotec tombs.

Science has been measuring whether size matters for years. A study with 3D simulation has the most complete answer

It is probably one of the most recurring questions in the history of humanity and, yet, one of the ones that accumulates the most myths per square meter. Leaving aside popular culture and internet forums, scientific literature has been trying for years to quantify what is true about the importance penis size. Science to the rescue. A published study This year, PLOS Biology wanted to resolve a question that has undoubtedly generated many jokes and also some complexes in the male sex. And the truth is that the short answer to this question is that size does matterbut perhaps not for the reasons most men believe. The signal theory. Until now, many studies were based on simple surveys to answer this question. However, this study has gone one step further by using 343 3D figures to evaluate the response of more than 800 participants. The goal was to understand penis size not only as a reproductive tool, but as an evolutionary signaling trait. The results. In the investigationfemale participants rated men as more attractive, which combined three factors: greater height, a “V” shaped torso (wide shoulders and narrow hips) and a larger penis. But there is a very important nuance. Attraction doesn’t follow a line of “the more the merrier” ad infinitum. The study in this case detected diminishing returns, since after a certain size, attractiveness does not increase proportionally, but rather there is a ceiling. Competence. But men also went through this study to evaluate the size of other men. In this case, it was highlighted that they perceived those with larger genitals as more competitive rivals and with greater fighting capacity. This suggests that, evolutionarily, the size could have served as both sexual ornament and a signal of status or threat towards other males, similar to the antlers of a deer. What they prefer. If we move away from evolutionary theory and go to stated preference, the baseline study remains the one published by N. Prause in PLOS One in 2015. This work is key because it differentiated, for the first time with rigor, between the type of relationship sought. In this case, using 3D models on heterosexual women, a preference was specifically shown for a slightly larger size, averaging about 16.3 cm in length in an erect state and 12.7 cm in circumference. But in the case of stable couples, the preference dropped slightly to 16 cm and 12.2 cm in circumference. The key reading. The first point to note is that circumference matters more than length in visual choice. The second is that these measures are only “slightly” above the population average. A mechanical reality. This is where science busts most porn myths. A narrative review published in the Journal of Sexual Medicine in 2023 analyzed the existing literature To answer the million-dollar question: does a larger penis give more pleasure? The answer is a very nuanced ‘it depends’. Science points out in this case that there are few high-quality studies that manage to directly link size with the organism, and the results are heterogeneous. But if we draw a clear conclusion, the truth is that the quality of the relationship such as trust or communication correlates more strongly with sexual satisfaction than the size of the penis. Male anxiety. If female preferences are moderate and satisfaction depends more on technique than size, why is there still so much anxiety among society? The studies in this case They point out that there is a great disconnection between reality and male perception, since approximately 38% of men report some degree of dissatisfaction with their penis. However, the vast majority of couples have a positive view of their partners’ genitals.

We have been relying on the Nutri-Score in stores for years. Science believes that its real impact is zero

He Nutriscore what we can see in some foods born with an ambitious promise: simplify the nutritional complexity of products into a code of easy to understand colors to know if a food is healthy or not. However, what on paper seemed like the definitive solution against obesity and poor diet is facing a much grayer scientific reality. His dark side. Although the idea seemed quite good, the reality is that new scientific reviews are setting off alarm bells. The conclusion being drawn is quite clear: the real impact on the shopping basket is minimal and the algorithm categorizes foods that are essential as something very bad. A good gap. One of the strongest arguments in favor of Nutri-Score comes from studies conducted in controlled environments, i.e. a laboratory. But what happens when we go down to the real, everyday world? This is what they wanted to analyze in a recent narrative reviewwhich evaluates consumer behavior in physical supermarkets and throws cold water on the system. And with this food color coding, the data shows that the improvement in the nutritional score of the purchase is only 2.5%. That is to say, it has hardly been noticed that a person begins to eat much more appropriate foods with this color code. Something that quite disagrees with the laboratory results that predicted that the effect was going to be much better. The real victim. The fact that some people’s shopping baskets have improved a little is the motivation that some producers of these foods have to change their ingredients to achieve a better Nutri-Score. as seen on Eroski. But this does not mean that citizens have changed the way they shop. The great blind spot. The fiercest criticism from the scientific field, highlighted by organizations such as the Puleva Nutrition Instituteis the omission of micronutrients. The current algorithm focuses almost exclusively on macronutrients, which are fat, sugars and proteins, but forgets other points that are fundamental. One of these points are vitamins and minerals, which are logically essential for the body, especially because some of them must be taken as they are not produced by the body. But polyphenols or bioactive compounds also stand out, which are essential antioxidants that can prevent chronic diseases. Unfair penalty. The system that is implemented right now also penalizes foods for their total fat content without differentiating whether they are healthy, something that has led to putting a bad score for olive oil. A paradoxical situation. The study from the University of Granada wanted to see the same thing about soluble cocoa to highlight these large discrepancies that force us to question Nutri-score. The result of the research team indicates that while pure cocoas with a higher bioactive profile can receive low grades such as C or D. But, on the other hand, others ultra-processed products with additives They achieve better scores, even A, simply by adjusting their sugar or fiber levels, without necessarily being healthier. Trying to correct it. The scientific community is no stranger to this problem and logically when something goes wrong you want to fix it to make it fit reality and that it truly fulfills the objective with which it was created. In fact, recent updates have already tried to correct the algorithm to better treat vegetable oils and nuts and penalize ultra-processed foods more strongly. However, the validations insist that, although there is an association between scores and macronutrientsthere remain huge gaps with comprehensive dietary guidelines. And we must keep in mind that the Nutri-Score measures “isolated nutrients” but not the overall quality of the food. ¿Where are we going? Science seems to indicate that the Nutri-Score is a useful but overly simplistic tool. By trying to condense health into a letter, nuances are lost that really make a difference in longevity and disease prevention. Although the algorithm is being refined to better align with European recommendations, the risk of the consumer blindly trusting an “A” for a processed product versus a “C” for a natural food remains present.

For thousands of years, human beings have avoided crossing the Taklamakan Desert. Now China is raising fish there

For more than 1,500 years, the merchants who traveled the Silk Road dared with oceans, mountains and jungles, they dared with endless walks, with warlords, with hunger and pain and the cold; with one of the most destructive epidemics in history; but they did not dare with the Taklamakan. That sand hell (whose name comes from the word ugiur for “abandon, leave alone, leave behind”) is not only the second largest dune desert in the world, but it moved, invaded and devoured everything around it. It’s been a nightmare for thousands of years. Well, now, China is farming fish right there. As? As it sounds, Xinjiang has been committed to producing fish and seafood “in the middle of the desert” for years. And no, obviously, it has nothing to do with “releasing fish in the sand” as if it were worms from Arrakis. The key is saline-alkaline water, lined ponds and recirculation techniques. It is not a revolutionary approach (already We have talked about similar techniques), but without a doubt Chinese producers are taking it to another level. Xinjiang aquaculture production was 196,500 tons in 2024. And, of course, the “desert seafood” boom raises questions about water, energy and scalability. From the promise of fresh fish… We are talking about a very harsh physical context (annual rainfall of less than 100 mm, very high evaporation and salinized soils): thus, the entire Tarim sub-basin depends on melting snow to provide water. Therefore, on the table, there are two clear approaches: the first, which has become popular in the Westtalks about the construction of monitored ponds. And this is already, in itself, very effective: “species such as grouper, mullet, shrimp, oysters and pearl musselsyes reach commercial size with survival rates close to 99%”, always according to the available data. But that’s just the beginning; just a proof of concept. …to the promise of mar. As explained by several chinese mediathe final horizon of the project is much more ambitious: creating a sea in the middle of the desert. That is, take advantage of the water associated with saline-alkaline soils and saline lakes to simulate marine conditions with technical adjustments, circulation systems and cultivation of microorganisms. And thus be able to breed species normally linked to the sea. But can that be done? Of course you can. We have the technology to do it. In a world where aquaculture already exceeds extractive fishing in volume, the interesting question is not that: the question is whether the model is scalable without aggravating tensions over water in a hyper-arid region dependent on snowmelt. What the industry that sees tons of fish emerging from the desert is asking is something even more basic: is it possible that the beginning of the end of commercial fishing is beginning?

A man rented two asbestos-filled buildings for 99 years. They were the Twin Towers, and six weeks later he made a fortune with 9/11

There are stories that seem like an urban legend because they fit too well with a movie script: a contract signed at the last minute, an invisible risk that no one wanted to look at in the face, and finally an event that changes everything. That’s why the story of an investor who decided attack to a ruinous business, it does not seem real, and the truth is that it was. A contract changed its meaning forever. In July 2001, the businessman Larry Silverstein signed the rent or lease at 99 years of the iconic World Trade Center complex, a deal then valued at around $3.2 billion that gave it operational control of a global symbol. Everything was more or less normal if it weren’t for the fact that a few weeks later 9/11 arrived and that business movement became a almost impossible story to tell without it sounding like a script: the “greatest real estate trophy” in Manhattan became the epicenter of the largest attack on American soil, with all that it implied in losses, contractual liability and clash with the State, public opinion and, above all, insurers. A ruinous business. The World Trade Center was not just any building, it was a logistical monster with expensive maintenance, complex technical decisions and a typical legacy of the great construction of the 20th century: asbestos, used for years as part of “fireproofing” projected onto steel and other materials, and which ended up being a problem health and economic huge for countless homeowners. In the case of the Towers, the use of materials with asbestos in construction phases, especially on the ground and middle floors of the North Tower, and that reality turned any renovation into a minefield of costs, controls and legal risks. In practice, the iconic value coexisted with an asset that was difficult to manage: expensive to maintain, delicate to intervene and with a liability that forced us to think about insurance as if it were part of the structure. Larry Silverstein The key insurance. When the complex collapsed, the debate stopped being “what happened” and became “what exactly does what was signed cover”, and there appears the detail that explains years of judicial war: at the time of the attack not all the definitive policies were closed, and part of the coverage rested on preliminary documents and debatable conditions. This allowed insurers cling to certain definitions and Silverstein to argue that the contractual framework should be read in the way that most protected its financial position. It was not a theoretical discussion, it was the difference between being ruined or having the resources to continue, rebuild and politically survive the earthquake that came after the disaster. The war of a word. The heart of the case was whether 9/11 counted as a single insured event or as two different events, since two planes and two towers were impacted. Silverstein defended that the terrorist attack was actually two attacks separated and, therefore, two events, one in each insured building, which justified aiming for figures close to double the “per occurrence” limit. The insurers, on the other hand, tried to fix it as a single event so as not to duplicate the exposure. The courts did not leave a clean and single ending, but rather a panorama divided into blocks: for some sections and insurers, interpretation was imposed of “an occurrence”and for others the door was opened to consider it two, creating a possible high compensation ceiling, but not necessarily automatic. The final amount. In the popular narrative it has been repeated that the man “tried to charge double” and that is essentially true, because his claims came to be raised in the around 7,000 million of dollars under the logic of two events. It turns out that the real framework was narrower: the total coverage “per occurrence” (building) moved around of the 3.2–3.5 billion and the litigation was cutting, distributing and limiting the maximum exposure according to which insurers fell under which definition. In practical terms, the story was not “he got paid twice and that’s it,” but rather that “he fought for two, partially won, and the system left him in a middle ground” that for years became in the great suspense Financial of Ground Zero. The big deal. After almost six years of battle and litigation, the outcome that mattered above the headlines was reached: an extrajudicial agreement of no less than 2 billion dollars with seven insurers announced with the intervention of the governor of New York, Eliot Spitzer, and the state superintendent of insurance, Eric R. Dinallo. That pact was presented as closing all claims pending and, above all, as the elimination of the last great barrier so that the publicized reconstruction of the complex could advance without the permanent brake of judicial uncertainty. Beyond the number, the key was the effect: resources and clarity to fulfill obligations and continue building in a place where each delay was a political, economic and symbolic problem at the same time. How it was distributed. The agreement was not a single check with a single destination, because in the same two actors lived together: the Port Authority as the public owner of the site and Silverstein himself as the private tenant and developer. The agreed distribution left approximately 56% for Silverstein and 44% for the Port Authority, and a direct implicit message: it was not about “getting rich” in a conventional sense, but about sustaining a project that had been tied to contracts, commitments and reconstruction. Furthermore, the confidentiality about how much each insurer paid separately reinforced the typical idea of ​​these endings: a functional closure to be able to turn the page and (re)build. The real story behind the myth. I counted ago a few years Snopes all the hoaxes that were given around the fascinating Silverstein story. Legend often tells it as an almost obscene stroke of luck, but the reality is more uncomfortable: Silverstein signed a huge lease just before the disaster, yes, … Read more

Apple has been resisting turning Siri into a chatbot for years. Until the evidence has been surrendered

2026 will be the year of Siri, but not because of an internal turn at Apple or because of the maturity of Apple Intelligence. It will be because the pact with Google will allow Apple to use Gemini technology as your assistant’s base. The details about what Apple will do with its assistant have not taken long to come to light and, we have good news: they will arrive in the next version of iOS. The new Siri. Apple has been announcing the benefits of the new Siri since before having prepared their news. With the Apple Intelligence announcement He put on the table a Siri completely integrated into the system, capable of functioning as a complete assistant and functioning mostly locally. The reality? Everything remains practically the same as before and, when Siri doesn’t know how to respond to something, ends up opening ChatGPT. What is going to change. They explain in Bloomberg that Apple, as of iOS 27will surrender to the chatbot model that has worked so well for companies like OpenAI and Google. The mere assistant model has expired, and Siri will become a chatbot at the service of any of our requests. This new chatbot will be integrated into all Apple apps (expecting an API open to developers to integrate it into their apps), allowing us, for example, to find specific photos in the app Photosfunction as a programming assistant in Xcodeetc. What won’t change. The only certainty with the new chatbot model is that Apple will continue to maintain its obsession with privacy and maintaining its AI ecosystem as its own, even if it is based on Gemini. Apple’s intention is to integrate this experience into iPhone, iPad, Mac and Apple Watchmaintaining activation through Voice command “Siri” or holding down the power button on the iPhone. The difference. Today, Siri is an assistant, a command system. You tell him something Siri classifies the intention (set an alarm, call X person, send a message) Execute the order Moving to the chatbot model means having a generative model capable of interpreting natural language, maintaining conversations and a more “human” interaction with the phone. This is what their rivals have been doing for a few years. Adapting to the inevitable. That Siri will evolve in 2026 is proof that the classic assistant model is exhausted. Apple will have to adopt the chatbot model as an inevitable transition, previously led by OpenAI and in which Gemini now seems to be leading the way. The thing doesn’t end here. The destination of the new Siri is not only current Apple devices. As my colleague Javier Pastor says, the company plans to launch a device without a screenits first AI-focused wearable. According to the leaked information, it will have a format similar to that of AirTags, a microphone system and a launch scheduled for 2027. New assistant, new devices, and alliance with Google. The new stage of artificial intelligence for Apple is finally arriving. The question is whether they will manage to offer something new.

Until now, Mexican children under 14 years of age did not have to pass an interview to enter the United States. That’s over

Mexico is preparing for an image that is difficult to see in recent years. With the changes in immigration policy and of access to the United States As a backdrop, the Trump administration has decided that both Mexicans under 14 and those over 79 will no longer be exempt to pass an interview with a consular officer to obtain their “non-immigrant” visas. In practice, this will affect children and the elderly who want to travel to the neighboring country to spend their holidays, for studies, business or for medical reasons. What has happened? That the US State Department has changed slightly the guidelines that Mexicans who want to apply for a nonimmigrant visawhich is used for tourism or business trips. And it has done so in an aspect that has generated some expectation in the country. From now on (from a few months ago actually) and as a general rule, Mexicans under 14 years of age and those over 79 must undergo a consular interview in person to obtain the document, just like the rest of the population. So far both (children and elderly) They used to be exempt. What does the US say exactly? The guideline collected in the official website of the US Embassy and Consulates in Mexico is quite clear: “All applicants for non-immigrant visas to the US, including those under 14 years of age and those over 79, will generally be required to appear for an in-person interview with a consular officer.” There are some exceptions, although for specific cases and as long as those involved meet “certain requirements”, such as presenting the petition in their country and not having been rejected before. For example, applicants for diplomatic visas or those who want to renew their B-1, B-2, B1/B2 permits or Border Crossing Card or Folio are exempt from the obligation. Of course, your passes cannot be expired for more than 12 months. This is also new, as remember The Country. Before they could take advantage of Dropbox process (visa interview waiver program) for 48 months following the expiration date of the document. Screenshot of the official website of the US Embassy and Consulates in Mexico. Why is it important? For several reasons. The first, as has been responsible for highlighting part of the Mexican press, is that in practice the change will mean that children and octogenarians will have to meet in person with a consular officer if they want to obtain their visa. In the case of minors under 14 years of age, it is no longer useful for their parents to come alone with all the documentation. The second reason is that the concept of “nonimmigrant visas” is broad. The list published by the US Department of State shows that its vast range includes those people who want to cross the Mexican border for business, tourism, to receive medical treatment, as athletes, to study or work as seasonal agricultural workers, among other cases. What do you recommend doing? The range is so wide that there are those who advises plan the procedures well in advance, especially at the busiest consulates, and starting from the base that the applicant will most likely have to pass the interview. The US administration itself remember That, if necessary, the consulate can request this procedure even from those who are exempt. Is it something exceptional? No. The US has tightened the access conditions for citizens of other countries (not just Mexico) and has become stricter with the requirements required of applicants for family-based immigrant visas. At the end of 2025 even transcended a proposal from Customs and Border Protection (CBP) and the Department of Homeland Security (DHS) that proposes that foreign travelers who want to cross the border in the United States must reveal up to five years of their network history. In the case of consular interviews for Mexican visa applicants, the change in criteria has come up against another handicap: a confusion in the dates. As remember The ImpartialIn July 2025, a guide was published that advanced the changes and stated that these would come into force as of September 2. According to a later update, the change was activated later: in October.
