Do we carry longevity in the blood? Popular wisdom would surely answer yes, that a family history full of octogenarians and nonagenarians is a good indicator that our life will be long. Science, however, seems to point out in the opposite direction. 17%. A new study on aging and longevity has calculated The weight that various factors have about our future health and the risk of premature death. One of the most surprising results is in the effect, relatively scarce, of genetic predisposition against environmental factors. The latter explain 17% of the variation in the risk of death in the population studied, a significantly greater than that of the low 2% associated with the genetic predisposition. According to the study responsible for the study, among the environmental factors with the greatest impact on this risk were smoking, the socioeconomic situation, physical activity and living conditions. “Our research demonstrates the deep impact of exhibitions that can be changed, either by individuals or through policies for the improvement of socio -economic conditions, reduction of smoking, or the promotion of physical activity,” explained in a press release Cornelia Van Duijn, co -author of the study. Different diseases, different forms of impact. The team also observed differences in the degree in which some factors or others hit the risk associated with certain diseases. The study showed that while environmental factors had a greater impact on some diseases (such as those that affected the lungs, heart and liver), genetics had a greater weight in dementias and in some cancers such as breast. Almost half a million participants. The study was conducted thanks to the data compiled by UK Biobank, a database with which the team could study the influence of a total of 164 environmental and genetic factors, and its impact on aging and premature deaths in the sample. Evaluating people aging is a complicated task. The team studied some diseases related to this process, but also resorted to a “new clock of aging”, a biological clock Based on some proteins present in the blood. The details of the process were published In an article In the magazine Nature Medicine. Lessons for the future. The results of the study can guide us when finding the focus on public health interventions. “These results underline the potential benefits of focusing interventions on environments, socio -economic contexts, and behaviors in the rpevention of diseases related to premature age and death,” Austin Argentieri addedwho led the work responsible for the work. Part of the relevance of the work is widely of the analyzed sample and the significant amount of data studied within the framework of the study. Manuel Collado, CNB-CSIC researcher at the CIMUS of the University of Santiago de Compostela, who was not involved in work, He stood out for Science Media Center Spain The robustness of the study, “a fantastic collection of samples and data of thousands of people who are being used intensely by many researchers. But, in addition, to add robustness to the study, their conclusions have also been confirmed in groups of people from different geographical areas. ” In Xataka | Every eight days an old man in Japan is killed by a member of his family.

Meta had no own app to compete with chatgpt. Mark Zuckerberg has already warned that this will change very soon

by

Goal is in a strange situation in the AI ​​segment. His Open Source model, calls, is something like the Linux of the AI. From it all kinds of derived developments arise, but while the company triumphs among independent academics and developers, it barely has a presence in the commercial world. And precisely that can change soon. Meta AI Independent APP in sight. According to sources close to the aforementioned project In CNBCGoal is preparing the launch of an independent AI application during the second quarter of 2025. Goal AI is an unknown veteran. The company launched its chatbot Goal AI In September 2023, a year and a half ago. However, the company preferred Integrate it into your social networks ” It was a curious movement, but it has caused it to be a great stranger. Susan Li, CFO of Meta, indicated that Meta AI has about 700 million monthly active users (at least they have opened it once a month). Goal needs its own chatgpt. And as a goal did not offer independent chatbot – it can be webbut not in the EU – the rivals have advanced him everywhere. Chatgpt has always been the referent, but Gemini, Claude, Deepseek or Co -People are now the clear options for those who want to access these tools. All of them offer independent applications on the mobile. Even perplexity does it. Here we have A good example in perplexitywhich is not only a search engine with AI but has become a way of accessing several AI models – Open Source – from the same interface. Goal can take advantage of that same approach since its own LLM is Open Source, but a goal AI has always focused on a flame exclusively. Zuck already warned. The Meta CEO, Mark Zuckerberg, stood out in his talk with investors in January his ambition in this area: “This is going to be the year in which a personalized assistant of high intelligence reaches more than 1,000 million people, and I hope that ai is that assistant of AI.” Did it twice. Not only said that to investors. On January 10 he answered a user who He suggested in Threads What a goal AI had its own independent application. Mark Zuckerberg’s response was an emoticon that represented that he agreed 100% with that suggestion. Subscription model in sight. In CNBC they reveal that Meta plans to collect a subscription for using Metaai, thus imitating the philosophy they have followed for example OpenAi, Google or Microsoft. The idea, as in those cases, is to offer a basic version without cost, and then more powerful, but paid versions.

The next generative AI revolution will not reason better, but integrate into physical robots. And will change robotics forever

by

In the technological world we are fascinated with chatbots who write essays and take their time reasoning. Grok 3 goes, Claude 3.7 It comes, meanwhile, something less visible but deeper is happening: The beginning of the merger between conversational and mechanical bodies. For the first time, robots not only execute preprogrammed instructions. Now also, in their own way, they understand. Historically, robotics and AI have followed separate paths. Parallel, but separate. Industrial robots were as accurate as stupid. AI systems are intelligent, but incorporeal. Let’s think about robotic arms that have existed on assembly lines for decades. Millimetrically exact, but absolutely lost If a single component appeared in a position slightly different from that expected. The new generation of robots connected to LLMS You can now interpret ambiguous instructions, such as “bring me something for thirst”, and solve the problem through reasoning (word of the year), evaluating which drinks are available, if the user showed preference for some and even if there is ice in the freezer. We no longer program specific movements, but rather general objectives. Figure robots are good examples. So good that even They work autonomously at a BMW factory. According to The company has just publishedthey can even receive generic verbal instructions, such as collecting pieces, and without the need for previous specific programming are able to visually analyze the environment and detect them. They can even pause, reassess the situation and correct the error if someone modifies the pieces. This contextual adaptation capacity was unthinkable a couple of years ago. The really groundbreaking of this impaired in robots is that You can learn very differently. The LLMS trained with text lack the physical understanding of the world. Traditional robots lack contextual intuition. By merging them an intelligence that includes both semantics and physics. A robot equipped with LLMS is not only able to understand the instruction “opens that box without damaging its content”, but can improvise before boxes never seen, evaluating materials, closures and fragilities. The revolution, unfortunately, will not be spectacular as in The novelty-fictionbut it will arrive in the form of robotic arms in factories that can be reconfigured with a verbal order. Or warehouse robots that will understand contextual priorities. Or medical assistants capable of interpreting non -verbalized needs of their patients. Boston Dynamics, the Non-Va-Más de la Robotica during this last decade thanks to your robots jumping and doing Parkourshe is no longer as interested in acrobatics as in integrating understanding systems that allow her machines Understand complex instructions in construction and industry environments. You just have to see Your website. And on the horizon look The Tesla optimus or the Cyberone de Xiaomi. Or unitree like One of the great Chinese technological bets. The big change will come When these systems stop failing before the unforeseen and begin to apply general principles of physical and contextual reasoning. We are not seeing the birth of artificial consciousness, but the understanding of the physical world and the world of meaning in a single integrated system. What this powerful convergence does is its silent nature. He catches us arguing On whether Grok 3 deserves a better product or about itself Chatgpt 4.5 It will be sufficient during the remaining of the year, but Robots are beginning to understand the world like us. Not only by calculating a trajectory, but understanding intentions, contexts and meanings. That is much more transformative and valuable than Any ten -page trial generated in seven minutes.

Musk’s lawyers want to change that law

by

Elon Musk has not lost the salary bonus that agreed With Tesla in 2018. Before The refusal of justice To grant it, he has made a determination: change the law to give him right. His lawyers are writing a proposal for bill that will change the rules of the game for companies in Delaware and compensation to their managers. If a law does not prove you right, change it. The law firm that represents Elon Musk and Tesla in their salary dispute with the company’s investors has been writing a bill aimed at changing corporate legislation in Delaware, as has confirmed the firm to CNBC. However, and despite the fact that the bill stops tailored to the case of Elon Musk, the buffet claims not to act on behalf of any specific client. “The statutory changes are necessary to restore the basic principles that have been the distinctive seal of Delaware for more than a century and ensure that Delaware remains the preeminent jurisdiction for incorporation,” said Lisa Schmidt, president of the law firm in statements to statements to the North American medium. Salary bonds do not touch. He bill that is proposed seeks to modify the Title 8 of the Delaware Code related to the fiduciary duty of executives and members of the Board of Directors that includes the General Corporations Law. The main approach of the proposal is to limit the demands related to executive compensation packages, as with the billionaire Bono that Elon Musk agreed with Tesla. This law proposal comes at a critical moment, since Musk faces the appeal of trial in the state of Delaware, where justice already has denied twice The payment of that bonus for considering it an “unfathomable and unfair sum.” Ready for vote. The bill written by the firm Richards, Layton & Finger that represents Musk and Tesla, has already been presented at the General Assembly of Delaware. It must now be voted in the two state chambers, and ratified by Democratic governor of Delaware, Matt Meyer. Brian Quinn, a corporate law professor at Boston College, assured CNBC that this proposal has not gone through the usual channels of the bills, which for decades have been debated and written in the Corporate Law Council of the State Bar Association of Delaware, not in a private law firm. Doubts about its retroactive effect. State senator Bryan Towsend, assured to ABC News that the effect of the new law “is not retroactive and would not affect the litigation related to the Elon Musk compensation package in Tesla.” Sarath Sanga, professor of corporate law at Yale University, does not coincide with this diagnosis of retroactivity and assured that: “It is possible. There is nothing in the law that demands it and there is nothing that prevents it.” Ann Lipton, a law professor at the University of Tulane, agreed with Sanga, noting that “this sends a strong signal to the Supreme Court of Delaware that we want this to interpret this to return to Elon his salary.” Brian Quinn also aligns with the opinion of his two colleagues in Yale and Tulane. “It is totally possible that the court revokes the opinion of the trial for reasons not related to this amendment and the Salary Package of Elon Musk is restored.” The new standard leaves shareholders unprotected. “The true role of corporate law is to protect minority investors. With this bill, the legislature is saying: ‘Do you know what? You have to protect them less,” explained Quinn to CNBC. Senator Elizabeth Warren, a higher rank member of the Senate Banking Committee, described the new bill as the “Musk’s last plan to cheat the US people and enrich themselves and their multimillion -dollar companions. Musk wants to write their own laws To snatch tens of billions of dollars from Tesla’s shareholders, after the courts said they could not do it, ” The senator declared for Massachusetts.

How to change all our passwords according to three cybersecurity experts

by

Passwords have become an essential part of everyone’s digital life. In combination with other verification methods, They are the entrance door to almost all the digital services we use. We need them to make online banking efforts, but also to log in to email accounts, social networks, streaming platforms or online stores. Like house keys, passwords must be well protected to avoid dislikes. But sometimes it is not enough to save them well: there are times when they should change them or reinforce security with additional methods. The question is when. In Xataka we have asked three cybersecurity experts to clear doubts and know what decisions we should make. The problem of security gaps Francisco ValenciaCEO of the Computer Security Company Secure & Itopened the conversation with a blunt phrase: “The user has to think that passwords Sooner or later they will expose themselves” What the expert tells us is relevant, because we usually navigate this increasingly digital and interconnected world without being completely aware of the threats that surround us. Valencia explains that the exposure of our passwords, or what is the same, that they have been committed or revealed, can occur in two ways: that they rob us directly or subtract them from the services where we have registered them. When we register in some online service, this should protect our authentication data, however, as the specialist points out, it is often not so. To illustrate it, the interviewee remembers Yahoo’s case. In 2013, with Marissa Mayer in front, the company starred in a colossal security failure, considered by many as one of the largest in history, which exposed the data of 500 million accounts. The platform “It seemed reasonably safebut the passwords were stolen and informed the users years later, ”he says. “The user has to think that the passwords sooner or later will be exposed.” Alejandro BotterCyber ​​Security Evangelist of Check Pointreveals that “it is increasingly common for a data gap to present.” The expert indicates that these types of scenarios where there is some type of data exfiltration can occur in any field, from a hotel to a bank, although the latter should, in theory, have more robust security measures. While the leaks of our passwords by those who are trusted are a reality, Botter warns that the most traditional security threats, those in which we deliver our passwords involuntarily, are still very present. “We might access a site that was not correct And let’s leave our password, or that the device will be infected, ”he explains. It also emphasizes that awareness is essential to understand that cybercounts not only pursue important objectives, but any white can be. “Many people say: ‘Where will my email be? I don’t think it’s my turn. ‘” In this regard, he mentions that tools such as “Have I Been Pwned? “The reality of information leaks account very palpably. Asked about whether we should trust the page created more than a decade ago by the Australian security consultant Troy huntBotter highlights the positive aspect of the platform, but says that “there is debate about it”, and that we do only email We are providing information that “it is achieved in different ways on the Internet and that is not so complex to achieve.” What are we wrong with our passwords? Adrián Arrow, cybersecurity technician INCIBE- Certhe tells us that “for years, passwords have been the main method of access to our accounts, but also represent one of the greatest security risks.” The specialist of this Spanish Institute adds that “the reality is that most users reuse keys, choose weak combinations or fall into phishing attacks.” Valencia supports this perspective with a practical example: “When we make an audit and, for example, we find a password of a person’s tennis club, it turns out that looking for password password We see it in another pile of sites because that same user has put the password on all sides. And that makes criticism even greater. ” The CEO of Secure & It emphasizes that one of the most critical problems of password reuse is that, generally, they end up leaking by the weakest link. Since the user has used the same set of characters in other services, many times together with the same email address, he ends up exposing all his accounts in a way that would not have occurred in case of using different passwords. “The reality is that most users reuse keys, choose weak combinations or fall into phishing attacks.” “Passwords cannot be the same in all sites. People many times have two passwords, the easy and difficult, and It turns out that it puts the difficult at the bank And something else and the easy thing in everything else. The password cannot be the same, it has to always be different, it has to be random, it has to be difficult to remember, etc. ” This, he explains, will force us to use a password management tool The interviewee adds some quite useful examples: “Knowing the exhibition, if they steal a password, they will exclusively attack the service where I put it. The Facebook password steals me, it will only affect Facebook, but not anything else. Until now the gravity is that if the Facebook password is stolen, it turns out that it is also for my bank and therefore the exhibition is much worse. ” Users usually ask if using a password manager is a good idea. Arrow, from Incibe, explains that “password managers are one of the safer and practical tools PARA store and manage our access credentials ”, and highlights some of its advantages. It lists that they not only serve to store passwords, but are also useful for generating them. “While no technology is infallible, a well -designed manager offers much more security than scoring paper passwords or trying to remember them all. Currently, there is no manual alternative that is so safe and practical. There are cloud and local versions (without connection), but … Read more

China has been cutting its technology for years. Xi Jiping has just opened the door for that to change

by

Jack Ma, “The Jeff Bezos de China”, It seemed to go directly to stardom. And what happened is that he crashed when he tried to launch Ant Financial Its alleged Fintech of 150,000 million dollars. Or rather, Xi Jinping, the Chinese president who made clear Who was commanded. Ma finished practically missing in actionbut now it has just appeared in an event with Jinping and other great executives of Chinese technology companies. That this happens is as surprising as it is interesting. XI Jinping Meeting with Technological Capos “in China. As they point out In Bloombergthe Chinese president presided on Monday a meeting in which several entrepreneurs and managers of large Chinese technology companies participated. Among them, of course, the presence of Jack Ma, co -founder of Alibaba – and who left the position of CEO in 2019 – that for the first time in years went to an event of this caliber. The major flat. The event was also attended among Ren Zhengfei (Founder and CEO of Huawei), Wang Chuanfu (Founder and CEO of Byd), Pony Ma (CEO of Tencent), Lei Jun (co -founder and CEO of Xiaomi), Wang Xing (CoFundador and CEO from Meituan) or Wang Xingxing (CEO of Unitree Robotics). Apparently nor Robin Li (CEO of Baidu) Ni Yiming Zhang (CEO of Bytedance) went to that event. During the event, they point out in The New York Times, XI asked these entrepreneurs to have the “ambition to serve the country.” And also the richest. The 2024 Forbes list With the richest people in China, it demonstrates that the technological and automobile sector is especially notable in terms of presence. Thus, if we search that list to the personalities of the technological segment in China we see many examples (with its position in that list in parentheses): Pony Ma (Aliaba) (2) Zhang Yiming (bytedance) (3) Colin Huang (Temu/Shein) (4) Robin Zeng (catl) (5) William ding (netease) (7) Jack Ma (ex-alibaba) (8) Wang Chuanfu (Byd) (9) Lei Jun (Xiaomi) (10) Those fortunes, of course, are far from the great fortunes that dominate the Forbes list globally. Thus, Pony Ma, the second greatest fortune in China, is the fortune 57 of the world. Lei Jun, in the 10th position of ranking in China, is 195 in the global ranking. More love for private companies. The meeting seems to point to a possible change in attitude on the part of the Chinese government, which in recent years has left the great Chinese technology act, but always making it clear who sent. AI can have a lot to do. The moment in which the meeting occurs coincides with the rapid development of AI models created by startups and Chinese companies. The actions of these companies have shown the renewed interest in the great Chinese technology: Tencent, who has just offered Deepseek R1 in Wechat, He marked The price record in the Chinese stock market in the last four years. China became hard with its technology. Ma ended up scalding after the terrible episode lived with Ant Group Co., and other executives seemed to learn the lesson. The government campaign launched at that time was responsible for reinforcing state control over the economy and stopping Chinese billionaires. The objective: to reorient resources towards the priorities of XI, such as national security and technological self -sufficiency. Closer to Xi Jinping’s policies. Since then Chinese technology companies have been much more aligned with the philosophy of Chinese president. Thus, the AI ​​models developed by some of these companies must first receive the approval of the government to be able to deploy and use in the country. More tolerance for private. In recent times Beijing has been softening its restrictive policies against Chinese private companies: Qwen, Alibaba’s model, is demonstrating the increasing relevance of the company in this field, but even Apple is managing to include its Apple Intelligence platform On the iPhone in China thanks to their agreements precisely with Alibaba. Chinese Millanoriocracy. In the US we are seeing how the great technological fortunes are aligned with Trump and yield to their policies or even drive them, as is the case of Elon Musk, the richest man in the world today. Chinese magnates have been aligned with Xi Jinping even longer. The influence of the Chinese government on the march of the country’s companies is even clearer and the AI ​​rise is probably the engine of this “repositioning.” His strategic value is evident, and the Chinese president now seems to want to give more margin of maneuver to private companies that are allowing him to compete in better conditions with his great rival, United States.

A new generation promises to change the rules of the game

by

China’s military modernization goes beyond Hightens or the New fighters. Yes, these are elements of superiority on the battlefield, also of deterrence and the country is investing a lot in modernizing and expanding its fleet, but something that they are also putting efforts is in the renewal of their submarines with nuclear capacity. After a not very successful type 094, China is finalizing the Type 096 nuclear submarine. And, of course, they have the attention of their main rivals in a scenario reminiscent of the Cold War. Reinforcing maritime presence. The modernization of the main military arms has become one of the main strategies of the Government of Xi Jinping. We are seeing advances in all areas, with examples such as New Earth’s Armament, PAIR DEVELOPMENTthe aforementioned aircraft carrier with The Electromagnetic Fujian at the head, Heavy helicopters, fighters and even Space armament. The leg that could be more lame in the Chinese Navy is that of the submarines of ballistic missiles, or SSBN for its acronym in English. Not only had few, but their designs and functioning had nothing to do with that of the most advanced powers in this context. Sample of this is type 094 of the beginning of the century. Type 094. Seeking to close the gap with the United States and maintain a persuasive presence in the South China Sea, the country launched type 094. It is a submarine with a load capacity of nuclear propulsion ballistic missiles and was the successor of the type 092 of the mid -1980s. It is estimated that there are six active units of this submarine, but it is a ship with lights and shadows. While their nuclear eyelets can reach the American coast from the South China Sea, the main objective of these submarines is deterrent and furtive presence (avoiding the detection of radars and enemy systems). The problem is that it is as noisy as the Soviet and American submarines of the 1970s. For a “new” submarine, it was an obvious skinny point because it made it very visible to the anti -submarine technologiesfrom the United States and its allies. And type 096. The reason for this noise is that its propulsion system is outdated (inspired by Soviet technology of the Cold War) and the design of the helmet, the propellers and the isolation system make it totally ineffective in furtive missions. China has launched more silent variants, such as type 094a, but they are still too loud. An easy target in the current anti -submarine war, goes. That’s where Type 096 enters the scene. There are six other submarines of this class with twice tons in tons and twice the capacity for ballistic missiles, but more than for its improvements for combat, what China is looking for is that it solves the predecessor problem. Thus, type 096 hopes to be as stealthy as more modern Russian submarines. It will also be loaded with improvements in the detection of rival submarines. Challenges. Part of the design efforts have been destined to cushion the noise of the engines, as indicated in SCMP. It is speculated that, similar to the new Russian submarines, the engines are mounted on huge rubber supports that help overshadow the sound. And it is also estimated that it will be ready by the end of this decade. Now, although they have Russia and the portfolio in their favor, experience is a degree and, precisely, is what China is missing in SSBN. Russia and the United States have decades of experience in this area and we will have to see when type 096 enters into play if China has achieved that leap that seeks in nuclear submarine design. Attracting looks. In ReutersNaval Technical Intelligence authorities and analysts estimate that “type 096 will be a nightmare.” The reason is that, according to them, “they will be very, very difficult to detect.” It is also said that Russia has shared part of its technology with China to improve that sound efficiency in its new submarine and that, although they do not think that Russia has shared its ‘crown jewels’ with China (because they would lose competitive advantage in case Something twists in the relationship), they are collaborating closely. In the United States analyst documents, it is speculated with the implications that such a weapon will have for the United States and its Indo-Pacific allies, since the presence of a vehicle like type 096 would have “deep” implications in a area of ​​special interest At present for numerous countries. Sample is the incident in June 2023, when a type 094 emerged in the Taiwan Strait, visualizing the constant tensionthat is lived in the area.

A new material with the help of Ruthenium wants to change the rules of green hydrogen

by

Renewables have postulated as the Future of Energyboth particular and in entire countries. They are also the present, with examples such as Sorpasso in countries like Spain and others like Uruguay pulling practically only renewables for months. Within those renewables, the development of methods to produce green hydrogen more efficiently is key. And a team of South Korean researchers They believe Having found the key to approaching that new era of green hydrogen: a new material that promises to revolutionize energy production. Colors. Hydrogen is extremely abundant in the universe, but it has a problem: finding it without being combined with other elements is very difficult. It is an element that has a great ease to combine and, to use it as a source of energy, it is necessary to separate it from those other elements. There are several ways to do itbut if we use renewables as an energy source, we can achieve what is known as ‘green hydrogen’. Catalysts. By means of the electrolysis technique, water hydrogen is separated. For hydrogen to be “green” it is necessary that, in that process, we use solar, wind or hydroelectric energy as a source of energy. Also an element that works as a catalyst, elements that accelerate the necessary chemical reactions to separate the hydrogen from the element to which it is linked. The better the catalyst, the faster the reaction occurs, making the process more efficient in time and resources. The problem is that they are usually expensive due to the presence of precious metals, which makes them little accessible and also have a high environmental impact because these metals are extracted from mining, some as part of Rare earth. No precious metals. That is why there are researchers experiencing with catalysts based on transition metals, non -metallic materials (such as graphene) and others that combine elements such as ruthenium, silicon and tungsten. Precisely, Ruthenium is the main ingredient of the new catalyst they are developing in the Group of Metrology of Emerging Materials of the Institute for Research and Science Science of Korea (or Kriss). The team had a catalyst with a molybdenum dioxide structure with nickel-molybdenum . They were clear that they had to investigate the Moo₂-Ni₄mo route as a catalyst, but not in their current state. Example of the electrolysis process to separate oxygen hydrogen Ruthenium shield. That’s when they decided to take the eye on Ruthenium. They introduced a small amount of this element into the structure of Moo₂-Ni₄mo and realized that, with river nanpoarticles of a size below the three nanometers, a thin layer was formed on the surface of the catalysts. Impact. This works as a shield that prevents degradation, improving durability. How much? According to its evaluations, the new catalyst presents a durability four times greater and is capable of lasting six times more in activity if compared to other existing commercial materials. All this without using rare or precious metals in the process. In addition, they combined the new catalyst with a photovoltaic system that uses Sovskita-Silicio solar cellsachieving conversion efficiency of 22.8% of solar to hydrogen. It is a promising result because it shows that this new catalyst is not only resistant and accessible, but efficient. Pocket. The problem of green hydrogen is that, although it is a fundamental element in our Way to Discarbonizationhis first appraisal has not been too encouraging. In December last year the first Iberian index of the price of renewable hydrogen was launched. Baptized as mibgas, The starting price was € 148.36/MWh. To compare, that of natural gas was about € 45.83/MWh. It was not something encouraging, but something completely normal due to the current production cost of hydrogen. Not only to talk about the infrastructure (with the entire system not only of electrolysis, but also of solar panels to feed the process), as well as the cost of the catalysts. That is why, cheaper catalysts that maintain high efficiency pave the way to the extraction of green hydrogen at a more restrained price. Looking at the sea. From the KRISS they are confident with their achievements because that new catalyst has not only marked with a green point the sections of price, efficiency and durability, but is exceeding expectations. Sun Hwa Park is the team’s principal researcher and has commented that these catalysts are also demonstrating high stability in saline water. “Currently, green hydrogen production requires purified water, but the use of real seawater could substantially reduce the costs associated with desalination. We plan to continue our research in this area. ” It will be the next challenge of a team that is not alone in this, since there are other teams and universities that have been proposed Exactly the same: use new transition compounds and metals to reduce precious metal dependence on catalysts. Now, everything indicates that it is something that will take time to establish and, without going any further, there we have the price of solar energy and how much it has dropped When technology has been popular.

Apple’s folding sounds more and more strength. It is a golden opportunity to change the smartphones market

by

We have been with the cantinela for years that “next year, Apple will present its folding smartphone.” And no, there is not always water in the river When it sounds. However, this start of 2025 starts with increasingly solid tracks About this project. The last They are related to Chinese manufacturer Lens Technology, who will supposedly manufacture the ultrafine glass that will supply 70% of Apple’s orders. Some of the company’s plans are also detailed to improve existing products. The problem? We have been with folding phones on the table for years, and they still do not be mature. Apple’s plan. Rumors are increasingly lighter, and everything indicates that in the first half of 2026 the company will make its folding iPhone known to the world. Apple would like to lose the closest part of the hinge, to achieve a greater thickness in the ultra -laced glass sheet and improve the durability of the product. Lens Technology would be the main glass manufacturer, with Samsung Display as a screen supplier itself. Technology to create a product that aspires to be the maximum reference in its territory. A little mature market. Foldables still do not democratize today. The price might seem the main reason, but we are strict, a Galaxy Z Flip6 it costs practically the same as a Galaxy S25+ And less than a Samsung Galaxy S25 Ultra. The problem of folding, despite the fact that manufacturers promise thousands of folds, is that they continue to throw durability doubts. A quick walk by Reddit shows Samsung mobile problems, Huawei either Xiaomi. In fact, in my own particular case I have suffered the wear and tear of the occasional folding … in just one week of use. A Chinese crown. If they ask you who is the king of folding phones, Samsung may come to mind, but it is not. Huawei It is, by far, the most folding company sells worldwide, well above Samsung, Honor and Motorola. The success of its folding range in China will not be easy to replicate for Apple, who may seek to settle in Europe as the main reference and popularize this telephone concept. Despite these figures, the folding market is still a minority. The question is whether Apple’s proposal will continue to be a niche product or if it will make the turns change.

At the end of last year Realme announced the real series 14 proa family composed of two terminals: the Realme 14 Pro and his older brother, the Realme 14 pro+. After being released in China, the company has just confirmed that the two smartphones They will be launched in Spain And, incidentally, he has revealed his official prices. These two devices are framed within the mid -range and stand out for the peculiar finish of the rear. Because? Because they are the first phones in the world that change color with the cold. Made the presentations, we will review the rest of the technical file and to know the official prices and availability.

One of the most striking features of the Realme 14 pro is that its rear changes color. The company has implemented a design called “Unique Pearl” that makes the rear have a texture “similar to that of a marine shell” (in principle, there are no two equal mobiles) that changes color with the cold. Thanks some Thermochromic pigmentsthe terminal changes from pearl to blue when the temperature drops from 16ºC. When the temperature rises, the color is white again. On the left the Realme 14 pro and the right model Pro+ | Image: Realme edited by Xataka This is one of the great claims, but we will have to wait to have it in hand to see how it works. For the rest, both models are quite similar: similar size, somewhat higher weight in the Pro+ model and a generous camera module in the upper area that houses two or three lenses, as we look at one model or another. On the screen the thing is not very different. Both ride Curvos OLED panels of 6.77 inches and 120 Hz of refresh rate, but curiously, it is the standard model that has levels of higher brightness: 800 nits in the Pro vs. 600 nits in Pro+. The same with the local peak brightness, whose difference is abysmal: 4,500 nits in the Pro vs. 1,500 nits in Pro+. In resolution, however, the older brother wins by scratching a good handful of pixels in both directions. Two engines, two brands Realme 14 Pro | Image: Realme There are significant differences in the engine, since the company has opted for MediaTk for the most “basic” model and by Qualcomm for the most complete model. Thus, Realme 14 pro rides a MEDATEK DIMENSITY 7300while the Realme 14 pro+ incorporates a Snapdragon 7s Gen 3 of Qualcomm. Differences in performance should not be very pronouncedbut it is likely that the Qualcomm model will exceed Benchmarks to Mediatek. However, the experience should really be couple especially because, otherwise, they are exactly the same. Both terminals incorporate up to 12 GB of RAM, up to medium Tera internal storage and the ability to expand RAM in a virtual way. The battery is the same in both models, 6,000 mAh, but the fast charge is much more powerful in the pro+. There are also no important differences in connectivity, beyond the pro+ model only admits Bluetooth 5.2. What should be highlighted is that neither of the two mobiles has NFC, so it will not be possible to pay with the mobile. What both models have is all kinds of AI functions, both edition and productivity. Clear differences in the camera Cameras del Realme 14 Pro+ | Image: Realme We pass to the part of the camera, which is where the crumb is and the big difference between both terminals. The Realme 14 Pro rides a really basic set consisting of a Sony IMX882 sensor of 50 megapixels and a monochrome sensor. That’s all. Neither wide angle nor telephoto, just a useful sensor and another support for light measurements. The older brother, meanwhile, has that same sensor under a Periscopic lens with optical zoom of three increases and up to 120 digital increases. The thing is that it is accompanied by a Sony IMX896 main sensor of 50 megapixels and a wide angle of eight megapixels. It is clearly a much more powerful camera. The Realme 14 pro+ rides a lot of cameras much more complete The same goes for the SEFIES. The Realme 14 Pro has a 16 megapixel sensor, while the Realme 14 pro+ folds the resolution and … Read more
