The truth behind the medical milestone that has returned activity to a frozen brain

by

One of the wishes of many people is to live forever and they may have in mind ending up with their head stuck in a jar like in the Futurama series or becoming cryogenized for an eternity until the key to eternal life is found. But we are still quite far from that, although right now science has been able to recover the activity of a brain after ‘killing’ it. Far from the resurrection. In recent days we have been sold the idea that we are facing a new way of ‘resurrecting’ the dead or achieving the wish of eternal life, but the reality is that the latest thing science has done is recover short-term functional activity in mouse brain tissue after subjecting it to vitrification. What was done. Historically, the great enemy of cryopreservation of human tissue have been ice crystals. This is because when we freeze tissue, the water in the cells expands and crystallizes, perforating the cell membranes and destroying the structure from within, making it impossible for that tissue to come back to life. Something that generates a lot of damage and that goes against the famous cryogenization cabins that promise to wake us up in the future when science has advanced a lot. But now, instead of traditional freezing, the latest experiment used powerful cryoprotectants and took mouse brain tissue to -150ºC. This process transforms the liquids into a glass-like state, preventing the formation of these crystals, and when they wanted to ‘awaken’ the tissue again, ultra-rapid reheating was simply done to prevent crystallization from destroying the samples. What was achieved. The original article shows extraordinary results, since the amount of neuronal properties that survived were many by ensuring that the cells did not collapse and the tissue returned to consuming energy normally. In addition, the neurons maintained their ability to fire signals and also the possibility of creating new connection networks, which is essential for learning and memory. Why does it matter? As he warns Nature Newsthese results must be read with caution, since it is mouse tissue, not a complete human brain. And recovering electrical activity in a cut of the hippocampus is not equivalent to restoring the consciousness, identity or life of an entire animal, much less a person. But even if they do not manage to pause our definitive death, the reality is that this can be crucial in the field of research by facilitating the transport and storage of brain samples for study in other places. But it will also allow drugs to be tested on actual brain tissue that has been preserved, perhaps reducing the need to sacrifice so many experimental animals.

Ukraine has returned from Europe with 250 fighter jets under its arm. The problem is that only Spain has told him the truth

by

The new European trip of the president of Ukraine, Volodymyr Zelensky, has finished in Spain and has crystallized into a military agenda that aims to reconfigure the Ukrainian air force over the next decade, based on political agreements of enormous symbolic scope. If nothing goes wrong, the Ukrainian nation has nothing less than 250 European fighters under his arm along with a huge aid package and arsenal. The problem is that the financing is very uncertain and its execution is very distant. Aerial reconstruction as a continental ambition. In Paris, the Ukrainian president signed a letter of intent to acquire up to one hundred Rafale fightersdevices that France presents as the heart of the future defense of Ukraine, complemented by Samp/T systemsnew generation drones, guided munitions and incipient industrial cooperation to manufacture interceptors on Ukrainian territory. The French bet aims to elevate Ukraine to European technological standardintegrating it into a long-term security architecture and relying on a financing framework yet to be defined, where the European Union and frozen Russian assets appear as the great promise, although deeply controversial. The political gesture, celebrated as historic in parisresponds to the French ambition to lead the regeneration of Ukrainian air power and to reinforce the role of its defense industry in a continent that is rapidly rearming. Doubts about the bet. Diplomatic enthusiasm contrasts with operational uncertainties. They remembered TWZ analysts either The Wall Street Journal that Ukraine does not have of the financial margin to pay for neither the acquisition nor the maintenance of a hundred Rafale, and France is going through a period of budget fragility which makes sustained long-term commitments difficult. The idea that Europe could finance the purchase through new joint debt mechanisms or from income generated by frozen Russian assets divides the states members and poses enormous legal risks, especially for Belgium, which holds most of those funds. Added to this is the industrial reality: the Dassault production chain is saturatedwith deliveries committed for years, and the manufacturing of 100 additional devices would require extraordinary efforts. The perspective of a parallel program, with 150 Swedish Gripen also agreed in the preliminary phase, increases doubts about whether Ukraine could sustain, train and maintain such a vast fleet of 4/5th generation aircraft. For many, the initiative reflects more a political movement to keep France at the center of the Ukrainian equation and to boost European industry in the face of a United States more distantthan a realistic military acquisition plan in the short or medium term. A Gripen fighter The military horizon. Zelensky’s trip has also highlighted the arrival of a winter that anticipates a new Russian campaign focused in energy infrastructure and strategic cities. France insists that Samp/T systems are demonstrating remarkable effectiveness against Russian missiles with a complex trajectory, even higher, some French commanders claim, than the performance of the Patriot in certain scenarios. In parallel, Paris reinforces its role as a provider of interim air capabilities, including Mirage fighters and precision ammunition, while promoting a future coalition of countries Europeans willing to guarantee the security of Ukraine after an eventual ceasefire, a project still impossible as long as Moscow rejects any negotiation. This strategy, which attempts to combine immediate support with an architecture of long term securityreveals both French determination and the continent’s real limitations in simultaneously sustaining the current war and future rearmament. Among others, Spanish military aid to Ukraine will consist of 40 IRIS-T missiles Spain and the contrast with the promises. The final stop of the trip, in Madrid, has revealed a very marked contrast between the declarative exuberance of some allies and the measured (and often austere) approach of the Spanish Government. Spain announced a package of 817 million of euros, which includes 300 million in nationally produced weapons, 215 million channeled through European programs and additional 100 million to acquire US missiles through PURL initiative of NATO. It is a significant effort in political and logistical terms, but modest in comparison with the great European powers and especially small in the face of the air ambitions presented in France or Sweden. In practice, it is a calibrated support for immediate needs from the Ukrainian winter: anti-aircraft missiles to repel drones and protect critical infrastructures, plus a commitment to accelerate joint industrial capabilities in areas where Spanish companies (with Indra at the head) can offer practical solutions such as deployable radars or anti-drone systems. Spain and realism. If you also want, the Spanish case reflects a much more realistic line than that of other countries visited by Zelensky. Since the beginning of the war, Spain has contributed with useful materialsbut in many cases coming from surplus (Leopard 2A4 retired, M113 obsolete, Hawk batteries aging) and has prioritized its participation in European programs where the direct cost to its budget is lower. In comparative terms, and especially measured as a percentage of GDP, Spain is far behind of the hard core of military support for Ukraine. However, what it offers now is probably more sincere and sustainable: an acceptable package, focused on urgent and realistic needs, that does not promise fighter fleets, perhaps impossible to finance, or industrial projects that exceed national capacity. Spanish extra ball. Furthermore, Spain stands out where other countries they can’t: in the reception of refugees, in the medical rehabilitation of Ukrainian soldiers and in light but reliable industrial cooperation. So, on that journey that began with spectacular advertisements in Paris and Stockholm, the Spanish stop has served to balance in a way the expectations. In that sense, Spain appears as one of the few allies that gauges its support by looking ahead. the budget figuresavoiding promising what it will be difficult to fulfill and remaining firm in what it can offer: a modest but operational contribution.

Grokipedia claims to aspire to the truth. An investigation has just shown that he cites neo-Nazi forums and conspiracy websites

by

The proposal of Grokipedia came accompanied by a direct message: aspire to “the truth and nothing but the truth,” as stated by Elon Musk in X. That statement takes on a new context. after the publication of a Cornell Tech study which examines how various entries are constructed and what fonts they use. The analysis shows that, along with content inherited almost literally from Wikipedia, there are articles that use sources cataloged by academic institutions and verification organizations such as neo-nazi spaces or openly conspiratorial sites. At first glance, Grokipedia takes on a familiar appearance: a home page dominated by a search engine and articles with headings and references. The inner workings, however, are much less transparent. Users do not have a clear system to suggest changes and, at the top of some entries, the label “Reviewed by Grok X weeks ago” appears, indicating an intervention by the AI ​​chatbot without detailing criteria or those responsible. In Wikipediathe edition history is public and allows each modification to be reconstructed. Grokipedia under the magnifying glass The aforementioned analysis compares both platforms on a large scale and points out that, although Grokipedia publishes longer articles and with twice as many citations as Wikipediamuch of its content comes from there. Of course, the coincidence varies: pages with a Creative Commons (CC) license present very high similarities, while those generated without that license are further removed from the original. One of the most delicate issues is the appearance of references to controversial platforms. InfoWars, which according to the authors is not cited even once on Wikipedia, has 34 mentions on Grokipedia. The pattern is repeated with other low credibility domains: Stormfront reaches 42 citations, LifeSiteNews reaches 100 and the Global Research and VoltaireNet sites register 51 and 45 references respectively. All of them are practically non-existent on Wikipedia, reflecting clear differences in source selection filters. Elon Musk’s entry in Grokipedia To mention a few examples, Leiden University characterizes Stormfront as a forum associated with right-wing extremism already current neo-naziswith a founder linked to Ku Klux Klan and a trajectory mentioned in several studies for its relationship with violent incidents. PolitiFact, on the other hand, defines Infowars as a portal dedicated to conspiracy theories and run by Alex Jonesa presenter known for promoting this type of content. This is what the edition history looks like in Grokipedia What appears in the study is not limited to counting how many times these domains are cited. It also highlights that the presence of sources considered unreliable or directly discarded by Wikipedia is much more widespread in Grokipedia. And one of the authors, in a text published in Indicatorcollects this accumulation of low-quality references to describe a broader pattern: Grokipedia seems to be making its own editorial decisions that alter the focus of certain topics. It remains to be seen how Grokipedia will evolve and what publishing model it will adopt as it grows. No encyclopedia works as a perfect reference —neither Wikipedia nor Grokipedia—, but they do operate with different mechanics. As we say, Wikipedia relies on an open community with standards, public debates and an accessible history of changes; Grokipedia, on the other hand, is based on criteria that are more difficult to follow from the outside, with an AI assistant that intervenes in the texts and without a clear human collaboration system.

Spanish agriculture is reaching its moment of truth

by

Tíjola is in Alto Almanzora, 700 meters above sea level; right between the Filabres mountain range and the Estancia mountain range. 35 degrees in summer, minimums around zero in winter. Esparto grass, rosemary, thyme, mastic. Some scattered pine forest. Little water, very little. Its water balance is negative almost all year round and, if it were not for the historical overexploitation of the aquifer and the Tajo-Segura transfer, nothing would grow except some almond trees, a little cereal and a handful of scattered olive trees. That is why the idea of ​​hectares and hectares of olive trees under intensive irrigation is so strange. Rare, but not impossible. In fact, according to the Almeria Ecologist Coordinatoris what is being done. SAT Olisurwhich has been working for years in the use of water resources, is carrying out the implementation of 14 hectares of irrigation. Something that, beyond the controversy, is above all an example that the big question of the moment is: at what price will those olive trees be grown? What impacts will be hidden behind intensive production in vulnerable areas? The end of an era. For thousands of years, olive trees have grown in the Mediterranean basin. It is a dry crop, with moderate densities and very close to the ground. The problem is that, in recent years, it has stopped being profitable. The best example is Andalusia. In the south of Spain, “good harvests have been obtained with 400mm per year.” However, in 2023 there are Andalusian dryland areas “that have not received even 200mm.” It was a catastrophe: a catastrophe that threatens to be repeated year after year. For this reason, more and more producers want to switch to irrigation. Because “dry” means “watered with what falls” and “irrigation” is “having water assured.” And the olive grove is good business, if you can water it. “The difficult thing is to have water because the Guadalquivir basin is already in deficit, so new concessions are not given,” explained Diego Barrancor a few years ago. Hence the olive trees are “fleeing” the Guadalquivir. And they go where they can. To Almería, for example. The diffuse limits of agricultural extractivism. The case of SAT Olisur is complex because, even if it seems like a bad idea, it is a company that has been working in the area for almost 30 years; who tries to survive with very bad cards. But not all cases are like this. In recent years, We have seen how ghost companies are dedicated to lease land, drain its resources and move on to the next thing. Agrarian extractivism is the order of the day and the conflict it’s inevitable. The crazy idea of ​​installing irrigated olive trees in Almería is simply an anecdote of an immense problem. The problem is that, as Hannah Arendt said, it is never easy to know the difference between a refuge and a trap.

The AI ​​industry has become a kind of ‘game of thrones’. And that reveals a worrying truth for your future

by

Sam Altman, CEO of Openai, must be pulling the hairs. In recent days Mark Zuckerberg, Meta CEO, “He has sneaked into his house” and has stolen no less than seven of his most valuable engineers. He has done it with the oldest tactics in the world. He money. In fact, the finish lines have shaken the foundations of the AI ​​industry, because it has not stopped spending true money with the aim of hiring all the talent of the IA that has been able. The situation has turned these engineers into the new superstars of Silicon Valley, with absolutely stratospheric salaries that are linked to the eternal promise that AI will end up changing the world. Goal is betting everything to that belief, and has decided to go for all spending huge fortunes Not already in data centersbut in talent. Let’s summarize: According to Altman himself, the Zuckerberg company offered initial bonds of 100 million dollars -although They were not exactly that – to some specific talents of AI to sign by goal. Fact offers reach 300 million dollars in four years According to Wired. Several of the “tempted” engineers per finishing have ended up accepting those millionaire offers. According to a internal statement From Zuckerberg himself, there have been 11 engineers who have signed by goal. Seven come from Openai, three from Google and one from Anthropic. Meta has also paid $ 14.9 billion for 49% participation in Scaleai, but above all for signing Alexandr Wangits CEO, which will now collect the new goal superintelligence division. They have also signed Nat Friedman, Exceiver of githubwhich will collect that new division with Wang. And they have just signed Daniel Gross, who Safe Superintelligence co -founded Together with Ilya Sutskever just a few months ago. For those last two target signings he has offered Buy a participation 49% in the Risk Capital Fund of Friedman and Gross, called NFDG. The value of the operation is unknown. Welcome to the Game of Thrones of the AI The last movements are nothing more than a confirmation of Zuckerberg’s voracity, which has moved quickly and with that irresistible hook of checks (almost) blank. And meanwhile, its competitors have been exposed to a reality: That AI has become a ‘game of thrones’. This industry is seeing from its beginnings and notable coming. At first, however, these internal movements were motivated by personal differences, visions or ambitions. Now many seem simply motivated by money. Thus, we saw how Openai’s origins became a new “Paypal Mafia” from which new startups arose. These first movements had a lot to do with a simple reason: some confudators and employees of OpenAi did not support Altman or did not share their vision. And that was how we saw several outstanding startups derived from those tensions: However, they all abandoned by OpenAi’s boat not so much for money – which probably also – as well as betting on another different vision. Of those “Morales” resignations We have gone to absolutely mercenary resignations in which money – and not the mission or vision of the company – is the clear factor of movement. That has made Altman recently said, there are two sides: that of the missionaries – which faithful to the companies in which they began their career, and that they believe in their vision and objectives – and the mercenaries that are sold to the highest bidder. AND According to Altman“The missionaries will overcome mercenaries.” The case of Sutskever, which confirmed yesterday the newsIt is especially painful, because now he runs out of his main adventure partner – Daniel Gross. The Sutskever startup is, as in the case of Murati, an absolute mystery: They have no visible productbut they have still achieved extraordinary investment rounds. It was in fact leaked that Zuckerberg came to make an offer to Sutskever To buy your startup, valued at 32,000 million dollars. Sutskever himself seemed to confirm that information by saying that “we feel flattered for their attention, but we are focused on our work.” Betrayals point to an awkward reality: AI is, above all, smoke These movements speak of a deeper problem in the AI ​​industry: those that can be trying to make their particular August, because it is not clear that the promises and the expectation generated by these companies end up becoming a reality. The clearest example is in the recent case of Daniel Gross, co -founder with Sutskever by Safe Superintelligence. In his message confirming the news of his partner’s departure, Sutskever said that “we have (the resources of) computing, the team and we know what to do. Together we will continue to build a safe superintelligence.” It is clear that Daniel Gross knew the same thing that Sutskever knows about the progress of that work, so, If they were so clear about the goal and knew how to achieve it, why change the side? If someone knew that he was going to win the race with his car, would he change it for another simply because they pay him for doing so? It makes no sense. And that tells us about the great truth of the world of AI: that despite all those expectations and all that money, nobody knows for sure if this technology will change the world as many believe it will change it. But in the meantime, the mercenaries will take advantage of it. Quevedo already said. Powerful gentleman is Don Money.

We are asking Chatgpt to value how handsome we are precisely because of what gives us the most: the truth

by

“Espejito, Espejito, who is the most beautiful in the kingdom?”, That famous question that was addressed to a enchanted mirror today is done to Chatgpt. The most curious thing about this “popular Prompt”It is the disposition of many people to follow the advice it can offer. Honesty. A 32 -year -old Australian woman, Ania Rucinski, Interviewed by The Washington PostHe said he asked Chatgpt how his partner could be more “attractive”, due to the lack of sincerity in his surroundings. The answer was direct and bluntly: curtain bangs. However, this is nothing new and is gaining popularity in social networks. A silent tendency. One of the videos that is gaining popularity in Tiktok is published by Marina (@marinagudov)which has reached more than half a million visits. It explained how chatbot has used to make a complete analysis of its style and aesthetics, from a selfie without makeup. The AI ​​indicated his ideal color palette, evaluated his hair tone, advised makeup changes with concrete marks and tones, and even designed a shadow look adapted to the shape of his eyes. The same did a journalist from Indy100which decided to follow the trend after watching multiple videos on social networks, and the same thing happened to influencer. The most surprising, as he recounts, was that the bot also offered a visually generated image with the result. Behind the virality. Why prefer the opinion of a bot rather than that of a human being? According to some users, AI is more honest without being cruel. Kayla Drew, too Interviewed by The Washington PostHe has claimed that he resorts to Chatgpt for everything, even beauty tips, because his direct way of speaking does not hurt as much as the criticism of a close person. For its part, for the same medium, the criticism of beauty Jessica Defined has offered a deeper explanation: “Humans have emotional ties that affect our perceptions. A bot, on the other hand, is not influenced by love, charisma or personality. Only analyzes data and gives their verdict. For those who seek clear answers about their appearance, that feels like an advantage.” There is something else. AI can contribute a more real future vision; It’s like launching a full pool. INDY100 journalist He has found In chatgpt a way of experiencing whether real consequences. The ability to prove, adjust and visualize before making a decision has become one of the main attractions of this trend. What do experts think? Some users interviewed by The Washington Post They have trusted In ChatGPT because it offers a “neutral” opinion, but specialists have warned that it is only an illusion. In the same medium, Emily Pfeiffer, an analyst at Forrester, stressed that “AI simply reflects what you see on the Internet, and much of that has been designed to make people feel bad about themselves and buy more products.” That is, their answers may be conditioned by a market logic that favors consumption, not necessarily the user’s well -being. For its part, Alex Hanna (Distributed AI Research Institute) and Emily Bender (computational linguist) go further by warning that training these models with content as forums that qualify the attractiveness (such as R/Rateme either Hot or Not) implies that we are “automating the male look.” Thus, the chatbot could perpetuate sexist beauty standards, instead of offering a fair or empathic evaluation. Along the same lines, as has detailed for the Argentine media writing Marzyeh Ghassemi, MIT teacher in computational medicine, her concern for how AI can offer harmful advice on sensitive issues. In a documented case, an AI recommended dangerous behaviors to people with eating disorders. This emphasizes that, without ethical supervision, these tools can cause damage even when they do not pretend it. The danger of digital culture. Beauty has always been changing, cultural and deeply subjective. However, artificial intelligence tends to reduce it to repeated and predictable patterns: skin without imperfections, thin bodies, Eurocentric features. That is, dominant standards that are not born from the individual, but from the market. As has pointed out The analyst Emily Pfeiffer, much of the content that trains these models has been designed to make us feel bad with ourselves and push ourselves to consumption. The AI, thus, not only offers advice: recommends products, suggests procedures, encourages spending. We convert the desire to feel better into a mathematical operation oriented to optimization. But optimization for what? To fit into an idealized image that others – or an algorithm – They have built? A study He has shown That systems such as Chatgpt reproduce systemic gender and race biases even in technical tasks such as personnel selection. If that happens in “neutral” contexts, what will not happen when IA evaluates something as culturally charged as physical attractiveness? Many of these models drink online forums and communities where the appearance, or darker spaces of the PERICA and The environments INCEL. These ecosystems not only normalize symbolic violence against bodies that do not fit in their canon, but now feed the databases with which we train artificial intelligences. Thus, what seems like an “objective” tool is, in fact, a deformed mirror: it returns not only idealized images, but the prejudices of an entire digital culture deeply marked by male desire, extreme individualism and the logic of competition.

Renault asks Japan to copy and make “small cars that people can buy.” The truth is that we don’t want them

by

The automobile market has forgotten small and simple cars. It is a reality for which it should be a perfect mobility solution for the middle European citizen. Now, Luca De Meo is committed to prioritizing the “small cars that people can buy.” But do these words make sense? “We don’t do it”. Because they are “unproductive,” according to Luca de Meo. Of those who speak are of small cars, of those of smaller size that, for the CEO of Renault, have completely killed European regulations. “We have to make small cars that people can buy again,” he said in an interview with Auto.it. “It is difficult for a regulator to know more than an engineer which is the best solution. Let’s leave engineers the best solution to reduce the impact of CO2,” said Meo to the questions of the Italian medium. The problem? For the CEO of Renault it is clear: “European regulation in the last 20 years has failed.” And this has been because “it was driven by the Germans, who wanted to make the most complex cars, because it suited them. That has had a devastating effect in other producing countries such as France, Italy and a little in Spain where people buy small cars because they do not have money or do not enter the cities.” The solution? Have your own regulation that It resembles that of Kei Car Japanese. These cars are extremely small, they cannot exceed 3.4 meters long or 1.48 meters wide. Nor equip yourself with an engine greater than 660 cc or 64 hp. In return, cars are not considered as such and, therefore, They do not have restriction problems that traditional vehicles in large cities have. In return, MEO slides not only the idea of ​​promoting small vehicles with new legislation, it also chooses to reduce the mandatory safety elements in cars of this size. “We were forced to add a security equipment valued at 400 euros. That on a Renault Twingo is a lot of money, in a sedan it is much less.” Too expensive. It is a usual criticism of the price of cars. They are too expensive for the client to allow them. Actually, although in recent years the price increase has been very pronounced, a car is cheaper now than 50 or 60 years ago. However, the ability to access the low range has been reduced. Pressing for other expenses of enormous cost, such as housing, the Spanish average citizen is opting for low -end vehicles when acquiring a new car. In what we have been, The best -selling car is Dacia Sanderofollowed by the MG ZS, the two cheapest cars in its segment. He is accompanied by Nissan Qashqai who has recently dropped price and the Renault Captur and Seat Arona, cars that barely exceed 20,000 euros starting. It does not come profitable. In his words, Luca de Meo is part of reason. Match the cheapest cars in safety equipment with the highest cost Price irremediably increases of this type of vehicles. By European regulationsthe cheapest car that is sold in our continent must have, among other systems, emergency braking, lane output alert or rear camera. However, it is also unquestionable that this equipment is an extra security for drivers who put themselves at the controls of a car. Although from Dacia (from the Renault Group) They have removed value for these measuresthese types of obligations guarantee a minimum of possible accidents to all drivers. Do we buy them? Luca de Meo’s words sound very good but … are we interested? If we attend to the number of Enrollments in our countryurban vehicles (such as the aforementioned Twingo) barely register 1.4% of registrations. They are the compact and the C-SUV (comparable by size) the most purchased vehicles in Spain, accumulating 48.5% of registrations. A segment followed by the utilities and B-SUV, which total 39.6% of the enrollment. Expanding the views to the rest of Europe, Discriminate Acea to vehicles in traditional sizes. A+B for utilities and urban (those of smaller size), followed by compact (c), medium size (d) and luxury (e and f). However, take the SUVs out of these categories. According to these data, in 2023 segment A and B that De MEO considers among the best selling remained at 21%, while the SUVs accumulated 51% of the registrations (between three and four times more than a decade ago). The little ones (taking into account that they add two segments) are not so far from 15% that compact accumulate. Do we want them? It is the other big question. According to the registration, we prefer larger vehicles. But, in addition, there is another constant: commercial failures among smaller vehicles. Although most European citizens make their daily journeys in urban environments, cars dedicated exclusively to the city remain little dear. WE HAVE SMART EXAMPLEconsidered a car too expensive despite being extremely useful in the European cities of intricate streets in historical and difficult parking helmets.

They have convinced us that thin mobiles have to sacrifice drums. It is half truth

by

The thinness of the smarpthone begins to be an issue. We don’t know why, but it is. Samsung has as your family’s star Samsung Galaxy S25 A mysterious Galaxy S25 Edge Ultradelgado. Oppo has obsessed with this data to improve the design of your Find N5and the strongest rumor on mobile technology by 2025 is the next iPhone 17 Aira model that will supposedly stand out for its data of thinness. Manufacturing a specially thin mobile usually comes from the hand of a usual problem: the battery is usually quite just. The Chinese manufacturer Tecno has shown that this does not have to be so and that, technically, it is possible to manufacture an extremely thin phone with a level battery. Tecno Spark Slim. Do not look for this phone on the Tecno website, because it is not on sale. The Spark Slim is the thinnest mobile in the world (at least, right now), with a thickness of only 5.75mm. It is almost half of what the most top phones usually have (which are around 8mm) and, all this, without sacrificing battery. Its battery is 5,200mah, a battery even larger than we find on much thicker phones. In addition, the weight is also a record: Tecno has been achieved by a figure of only 140 grams. We do not know its processor, although the company tells us that it has not yet been presented. The screen is of no less than 6.78 inches, amoled and with a 4,500 nits peak shine, so we are not facing a reduced SPECS phone. The key… and the sacrifices. Tecno has not relieved images of the internal construction of his Spark Slim, but it does give a curious fact: his battery has a thickness of only 4mm. A record has been achieved, introducing a much larger battery than usual is an extremely thin phone. Although we have not been able to try it thoroughly, achieving something like this always has costs. Otherwise, all manufacturers would follow this path. If we look at the camera module, it can be seen that the sensors seem quite small. It is inevitable: if the vast majority of the body is drums, there is not too much space for large sensors. To achieve this thickness, it is also difficult to add elements such as steam cameras, large speakers, or other elements that enrich hardware. Despite this, it seems clear that any user needs: a great battery, a processor, and a couple of cameras. An inevitable trend. Achieving extreme thinness is a trend. The great manufacturers (OPPO, Samsung and expected Apple) begin to a race whose purpose we do not know, and whose future sales will reveal the unknown: whether to fight for thinness really revives demand, or if it is a race without too much sense.
