The new revolutionary technique to say goodbye to glasses

by

We are thousands of people who We have gone through an operating room to submit to a Lasik surgery To correct the vision problem and say goodbye to glasses definitively. And although this is very safe and very common surgery in the day -to -day life of many ophthalmologists, it is still a surgery that is literally “carving” the cornea. Now a research team proposes a radical alternative: correcting vision without lasers, without cuts and in approximately a minute. A new tennic one that already has a name. Through the autumn meeting From the American Chemical Society (ACS), the researchers They presented a technique To remodel the cornea, a small electric current and a kind of platinum lentilla will be used to remodel the tissue precisely and less invasive. This is what they have called Electromechanical remodeling (EMR). The ‘Kit of the matter’ lies in the cornea. To understand innovation, you must first know that The cornea is the transparent ‘dome’ that we find in the front of the eye. Its function is to focus the light on the retina where the cones and canes that are responsible for interpreting the shapes or colors are found. If the shape of this cornea is not perfect, the image that reaches the brain is blurred, giving a pathology that we can know how myopiaFreemetropia or astigmatism. This means that when we want to operate to eliminate these pathologies, the state and thickness of the cornea have to be analyzed. The problem of lasik: “carving” the eye. Lasik surgery Correct this using a laser to eliminate or “carve” microscopic portions of corneal tissue and give it the proper shape. As explained Michael Hill, professor of chemistry at the western College and one of the authors of the study, “LASIK is just an elegant way to do traditional surgery. It is still tissue carving, only with a laser.” In this way, the elimination of a fabric that will never recover is highlighted as a negative point of this surgery. In addition, surgery also conditions have an adequate cornea thickness so that the surgeon can eliminate enough tissue to achieve a good result. And in some people the cornea is really fine. Having this problem in front, the objective of research equipment was clear: mold the fabric instead of eliminating it. Chemistry to make the malleable cornea. The key to this new technique lies in the composition of the cornea. This fabric, rich in collagen, maintains its shape thanks to a network of ionic links between components with opposite loads. The research team, led by Hill and the surgeon Brian Wong of the University of California, discovered that they could “temporarily loosen” this network. Although it was a result they saw almost by accident. The process to get a malleable cornea. For understand how they can do it In a simple way, we will divide the process into the following points: Everything begins by applying a small electrical potential on corneal tissue through an electrode. This current causes the electrolysis of the water present in the tissue, which reduces the pH of the tissue to make it more acidic. This acidity neutralizes the negative loads within the collagen matrix, weakening the links that rigidly keep the cornea, so it will temporarily be malleable to give it the way you want. Once the electric current is removed, the pH returns to its physiological state and the ionic bonds network is restored, causing the cornea to be ‘rigid’ again. Correcting myopia in 10 minutes. To prove their theory, they created some platinum “lenses” that served as a mold with the form of corrected cornea. They placed these in twelve rabbit ocular balloons Ex vivo (that is, they were removed from the animal) and that they were submerged in saline solution to simulate tears. In the 10 eyes that simulated myopia, the result was a success. After applying the electric current for approximately one minute, the cornea curvature adapted perfectly to the shape of the platinum lentilla, correcting the refractive defect. All this at the same time as Lasik technique lasts, but with less steps, a cheaper team and without having to make an incision. A promising future, but with obstacles. Although the theory has worked in these eyes, there is still many steps to take. The fact that a treatment of this caliber reaches a patient is a process that can take many years. At the moment, the next step is to move on to the experimentation in animals, including mice that are alive, in order to evaluate the safety of the procedure. Subsequently, and after the approval of the FDA, You can go through humans in their different scales. In this way, we can go to the next decade before seeing it announce as a valid treatment. Although they also have the financing of the project that is in the air right now. Other uses are also explored. In addition to being a suitable treatment for myopia, farsightedness or astigmatism, the technique could have other applications. One of them is the ability of surgery to reverse certain types of corneal opacity that are caused by exposure to chemicals. This is something that could only be treated with a complete cornea transplant. Aesthetic surgeries are the order of the day. The fact of removing glasses is much For aesthetic reasons and comfort, something that is the order of the day. We have already seen how there are people capable of breaking their bones by have a few centimeters tall or as in the United States Surgery is popularized to make an eye color change. But it’s not something now, since 2,000 years ago The Romans themselves did these surgeries To be able to change the physical.

Chinese startups are unseatting the owner and lady of Asian technology: Baidu

by

In the stock market there is a metric that is observed almost with reverential respect. It is about Per (Price to Earnings Ratio), which It allows us to know If an action is expensive or cheap. And when we observe the technological market in China, there is a company with a worrying per: Baidu. Fall of a giant. This Thursday Baidu has published terrible financial results: Fall of quarterly income It is the worst of the last three years and that has caused a 3% drop in the value of the shares in the Hong Kong Stock Exchange. Source: Bloomberg. Per worrying. Not only that: Baidu is now around 9.7, which is the least of all the companies that are in benefits in the Hang Seng Tech index (Hstech) than It serves as a reference When comparing Chinese technology companies. The action, speaking in silver, is too cheap. The search engine loses bellows. For decades Baidu has been considered “the Chinese Google”, but over time its relevance has been blurred. The Chinese young They do not know what is to search in Baidu or Googleand have come to other ways to find answers. Fierce competitors. Platforms such as Tiktok or Instagram have become a spectacular alternative for new generations, and in China we have seen as similar social networks –Xiaohongshu and Douyin– They are getting that. Eric Shen, analyst at the consultant Third Bridge, explained How “these rivals have created content ecosystems that seem more dynamic and attractive, which moves users of the most static and Baidu website.” A disappointing 2025. But there is also AI. And there Baidu has a problem. Baidu’s action has lost a 3% value since the year began. The figure is surprising, especially since its competers focused on AI have a 24%win. Where is Baidu AI? Baidu reacted relatively fast and presented its competitor to Chatgpt in March 2023. It was called Ernie, but from the beginning The performance of that model gave problems. Since then his trajectory has been irregular, and the rise of Deepseek and of Other Chinese models like Qwen (Alibaba) or Doubao (Bytedance) has put it in more and more problems in that market of “IAS Socialist”. An AI that tries to overcome. In February Baidu wanted not to get off the revolution caused by Depseek, so he offered a free version of Ernie last April. Your last model, Ernie 4.5, It’s Open Source – initially they had adopted a proprietary model – but even that does not seem to have encouraged things for now, and there is not too much talk about their capacity: the popularity of other models such as Deepseek or Qwen is now greater. Baidu Lance Ernie 5.0 is expected at the end of August, and it will be then when we can check if this edition does compete in a specially frantic market. Back in view? Analysts believe that Baidu’s latest strategic decisions could help her recover the good path. Among them include investments In Robotaxis And, of course, in new initiatives to boost their AI models.

China was isolated from one of the key arteries of the Internet for an hour. It is not clear if it was an essay or a failure

by

On the Internet there are falls that are noticed. And then there is what happened in China. For a whole hour, one of the main road traffic with the outside stopped working without explanation. It was not a total blackout, but a cut that became visible in many parts: applications that were halfway, websites that did not respond, services that failed right in the border crossing. The ruling did not fit with the typical local fall or with a problem of a single operator. It lasted 74 minutes, crossed networks and left behind an awkward silence. What fell was not all the Internet, but a concrete and widely used part: the channel that allows encrypted connections to function safely. According to GFW Reportbetween 00:34 and 01:48 of August 20, Beijing time (UTC+8), a generalized blockade was recorded in the Port 443which is the one that uses the majority of traffic HTTPS. The effect was broad and sustained, but did not affect other channels. The most striking thing is that, until now, no one has explained what caused that cut or why it happened in that strip. The technical analysis points to a very concrete pattern. Every time a connection tried to settle in that port, special packages – the RST+ACK – appeared that act as a closing order. They are the digital equivalent to hang the phone before someone attends. These packages were not sent by mistake: they were being injected into large quantities just at the key moment of the exchange between client and server. According to the specialists, this alteration did not fit with a fall due to congestion and affected both connections that came out of China and to those trying to enter. Despite the serious cut, not everything stopped working. Internal connections within China were still active, and other ports, such as 80 – for non -encrypted traffic – or 22, intended for remote connections, showed no block signs. The problem was focused on port 443. That explains why some services could continue to work while others became inaccessible: it was not a total disconnection, but a very selective interruption of the encryption step that crosses the digital border of the country. There are no public reports indicating that platforms such as WechatBaidu or Weibo suffered a generalized fall in that strip; Its main infrastructure is mostly within the country and does not depend on the international crossing for basic functions. But many Chinese apps incorporate components that depend on Servers outside of China-action, mini-programs, external APIS or cloud functions-and those calls could fail when the encrypted step was blocked. There are no public reports that indicate that platforms such as Wechat, Baidu or Weibo suffered a general fall in that strip The impact was more noticeable in international services. According to The Registerpart of the connections of foreign services – including some functions of Apple or Tesla – could be interrupted for users in China during the blockade window. Other international services that depend on HTTPS, such as certain CDNS or VPN connections that use TCP/443. In summary: the internal network was not broken, the encrypted channel was cut out and that was enough to leave many out. One of the most relevant clues is precisely that technical footprint. Each system that filters or interrupts connections leaves a trail –a fingerprint– Recognizable for the order of the packages, the TTL or the TCP window size. In this case, these values ​​differ from the previous documents, so the researchers propose two hypotheses: a new equipment deployed for tests or a known team that was in an anomalous or poorly configured state. The conclusions remain in condition until there are more data. Traffic returned to normal and there were no visible consequences on a large scale.But the cut was real, it was documented and left an unknown in the air. There were no officials or official explanations. In any case, the great firewall is still there, functioning as always, and with an intervention capacity that this time was recorded.

A single click and goodbye to our passwords. This is the vulnerability that affects the extensions of several managers

by

We trust our Password managers as if they were digital safes. But, According to expert Marek Tóthjust visit the wrong website and click where it does not correspond to put that armor at risk. The technique presented in Def with 33 does not point to applications, but to extensions we use daily In the browser. In his tests, he ensures that this gesture can activate an information theft system without the user perceiving it. The research, made public in one of the main international conferences of computer security, documents how eleven extensions of password managers could be manipulated to filter data. Toth states that he notified the finding of manufacturers in April 2025 and that in mid -August several still still had corrections. The study includes practical tests, websites designed to demonstrate the failure and an estimate of the scope: about 40 million potentially exposed active facilities. How the attack works and why it affects you The technique described by Tóth is based on hiding the elements that the extensions insert on the page so that the user interacts with them without seeing it. With minimal changes in opacity or overlapthe attacker gets that The self -fulfilling is activated in the background. And there are several ways to achieve it, from manipulating the root element of the extension to altering the entire body of the site, in addition to variants by overlap. The most delicate scenario appears when a trap website is not necessary, but it is enough to take advantage of a legitimate page with a security failure. In those cases, he explains, the attacker can capture login credentials. The risk increases because many managers fill data not only in the original domain, but also in subdomains, which expands the attack surface without the user noticing it. According to data published by Tóth and collected by Socketon August 19, 1Password, Bitwarden, ENPASS, were continued as vulnerable Icloud PasswordsLastpass and Logmeonce. On August 20, Socket updated that Bitwarden had sent version 2025.8.0 with a patch, pending distribution in extensions. Among the managers who did apply corrective measures are NordPass, Dashlane, Keeper, Protonass and Roboform. Of course, this list can vary at any time if other companies publish arrangements after the dissemination. Extension of password manager for the browser The manufacturers reaction was disparate. Socket points out that 1Password and Lastpass classified the ruling as “informative”, a category that usually implies absence of immediate changes. Bitwarden, ENPASS and Apple (Icloud Passwords) confirmed that They work in updateswhile Logmeonce did not respond to contact attempts. Some companies admitted the existence of risk, but related to external vulnerabilities at the sites visited. While some developers decide how to act, Toth and Socket team agree that there are practical measures to reduce exposure. One of the most effective is to deactivate the manual self -fulfilling and resort to copying and paste. It is also recommended to configure the automatic filling only for exact URL coincidences, preventing it from working in subdomains. In chromium -based browsers, the use of the extension can be limited with the access option “When clicking”, so that the user explicitly authorizes each use. The researcher shows how it is possible to overlap invisible elements on the page to deceive the user and press the password manager without realizing it Not everything is as immediate as clicking and losing everything. For the attack to succeed, the extension must be unlocked, the browser has not restarted and the user interact at the right time. In addition, the analysis focused only on eleven extensions. There is no evidence that All solutions The market is vulnerable, although the expert warns that the pattern can be repeated in other types of extensions. The weak point is in the SUNthe internal structure used by websites to organize buttons, forms or menus. Password managers insert their elements there, and if a malicious page manages to move them, hide or force them, the user can end up clicking without realizing it. That same risk extends to other extensions such as cryptocurrency wallets or notes applications.

OpenAi already enters 1,000 million dollars per month. They are crumbs compared to what you need to be profitable

by

The launch of GPT-5 It has been rather disappointing for users at street level and has arrived accompanied by some problemssomething that has recognized the Sam AltmanCEO of OpenAi. However, it is sweeping a key sector: Companiesfor the quality of its reasoning models and its price. Not being a company that quotes in the stock market, the doubt is how much success translates into large income, and Sarah Friar, Financial Director of OpenAi has given a key fact: OpenAi has entered 1,000 million dollars in a month (July) for the first time in its history. Results as good as insufficient. Openai’s reality is that it is still early to celebrate a figure like that announced by Friar, especially when the executive recognized that artificial intelligence “right now is voracious in GPU and in a computational power.” In that sense, he affirmed that the biggest problem they face is “being constantly under computational capacity.” That is, the demand for the use of GPUs of its models is greater than the resources they have to cover it. The plan to cover your needs is clear, and Friar recalled it: “That is why we launch Stargate”, in reference to that Historical project In which partners such as Microsoft, Oracle, Nvidia and ARM participate, and in which they expect to spend 500,000 million. They expect, because There is still no single contract signedand find more sources of financing It is a huge challenge. With this financial context, the 1,000 million dollars that OpenAi already enters a month are totally insufficient. They look for solutions, but more complications arise along the way. The reality of artificial intelligence according to Sam Altman is that his demand will continue to grow, their training needs will continue to grow and spend “probably more aggressively than any company has done in something for progress.” Given this need, OpenAi seeks solutions, such as selling 6,000 million in shares with an assessment of 500,000 million dollars, after raise 40,000 million in a financing round at the end of Marchwith an assessment of 300,000 million. 18,000 million were going to dedicate themselves to the Stargate projector. The problem is that to get the last 30,000 million of that round, Openai had to become a “For-Profit” company, a path that He has recently abandoned. A problem structure of expenses. As much as Openai continues to have the confidence of large investors such as Softbank or Microsoft, the problem is that the company’s expenses are huge. Not being a quoted company we cannot know official figures, but estimates point to 8,000 million operating expenses per year (They do not count investments, infrastructure or other financial obligations). Even if it continues to enter the current rhythm (1 billion per month), in 2025 it would not go from 12,000 (the estimate they handled for this year, According to The Information). That is, only their operating expenses “eat” 66% of the operating expenses, which do not contemplate their higher volume investments. The cost scheme is very complicated, and Sam Altman came to affirm that They lost money even with chatgpt prothe subscription of 229 euros per month. And the profitability for when. According to An internal studyOpenai will lose 44,000 million dollars between 2023 and 2028, and 14,000 million only in 2026, the triple of those estimated by 2024. It will have to wait four more years, until 2029, so that the company exceeds the Break Even And I achieve The long -awaited profitability. It is something they estimate that they would get 100,000 million dollars annually. Right now, viral moments such as the generation of chatgpt ys imagesor explosion of images of Ghibli either help: “Derritate” servers with a huge cost. The good news is that Sarah Friar confirmed that they have seen acceleration in the adoption of payment subscriptions. But much remains to stop losing money.

Tesla has launched in China a Model and L. It is the most Chinese (and logic) bet that could do in the short term

by

After months in which he has signed up for a Tesla Model and smallsomething cheaper to boost sales in Europe and press the competition for price, Tesla has surprised us with quite the opposite: a tesla model and longer. Only for China. And it makes all the meaning. The new Tesla Model Ylthat is, the elongated body version of the well -known electric SUV, increases the 150 millimeter wheelbase and its height in another 44 millimeters. A six -seater configuration is adopted (2+2+2) Therefore, a third row of seats is added that has been somewhat controversial. But it is also provided with heating and ventilation to the seats, electrical plates and integrated speakers. They are small improvements to increase the comfort of the passengers that are in tune with the bets of the L versions that the rivals usually offer in China. A category of vehicles that are based on three fundamental pillars: more space and more comfort for passengers. And that, curiously, they are transverse to all types of sizes. Purely Chinese With the presentation of Tesla Model YL, the opinions between criticism and public have been divided as usually happens with Elon Musk’s company. In Hybrids and electric They point out that some media qualify the third row like “going mounted in a convertible”given the little size between the head of the passenger and the roof. They ensure that the space that is free in the legs for a 1.70 -meter person is minimal and that it is an emergency solution for adults. In social networks a whole debate has been mounted following some images in which the same adult is seen sitting in the third row of seats. In one of them You see how it has a lot of free height between the head and the roof and ensures that it measures almost 1.90 meters. In another image it is observed as, with the trunk open, that same adult I would have serious problems traveling comfortably. Personally, I am inclined to think that the second option is the real but that does not mean that Tesla’s bet is bad. Yes, there are rivals that have a third row of more comfortable or practical seats. We have verified it in the Hyundai ioniq 9 or his brother, the KIA EV9. However, they are cars created from scratch with this intention in mind. Tesla is adding a third row of seats with a body L to improve the versatility of the car but, above all, with the intention of improving the comfort of the second row. That third row is an emergency solution and the really interesting is in a second row of a 2+2 configuration car with two good seats with all the comforts desired by a passenger. And in China the bodies L are usual. These cars are versions with longer bodies, with more wheelbase to generate a greater interior space. Europe has tired of selling this type of cars and Audi there, for example, demonstrates that the phenomenon is transverse to the size of the vehicle. The Germans have sold in China the Audi a3 l But also in those cars that, for European standards, already seem huge and do not need more interior space. Example? An Audi A8 L. To get an idea, this last car can exceed 5.19 meters to some endless 5.32 meters or impressive 5.45 meters. The latter refer to Audi A8 l horch. But the most interesting is in its interior seats with resting function or the possibility of adding a fridge in the central compartment, among other possibilities within the company’s customization program. Obviously, we talk here about a luxury car that Tesla does not intend to match but the company’s movement clearly points to proposing an experience in the cabin that is very sought in the Chinese car, transforming the interior into a kind of lounge with more space where feeling as comfortable as possible. Keep in mind that the great Chinese metropolis are huge and that the paths can languish for many minutes before the driver reaches his destination. This has made Chinese cars (and Europeans who want to sell there) have thrown into the arms of the screens and connectivity. But also that very wide rear seats are prioritized. Even sacrificing a good part of the trunk where Chinese cars tend to lose in front of the rivals. This happens because, despite its enormous sizes, in China the car is a Priority urban vehicle. It is rare that you travel with them since the distances are so long and the trains so competitive that either it is traveling in high speed or by plane. That is, cars are spaces with wheels where it is about giving the highest comfort to the client (another good example is the rise of their luxury minorities). And that is why the L -bodies L versions do not seek to have a third row of very comfortable seats. It is about prioritizing central seats in a 2+2+2 configuration and, in the best case, add a third emergency option. That is what Tesla has done.

An army of robot dogs

by

Hong Kong is preparing to combat the increase in cases of the Chikungunya virus, transmitted through mosquitoeswith a strategy taken from the Black Mirror series: with robots dogs. The authorities themselves They are already planning Deploy these four -legged robots equipped with insecticides to deal with the threat in difficult access areas. What is the ‘chikungunya’ disease. In summary, it is an infectious disease that is transmitted through mosquitoes that have the virus inside being the vectors of the disease. The symptoms generally begin four to eight days after the mosquito sting, and mainly will be accompanied by fever and joint pain. At the moment, there is no treatment because it is a virus, and the health system can only focus on treating symptoms. The problem is that the concern for the disease does not stop growing. Recently, nine imported cases have been registered this year and one significant out of the neighboring province of Guangdongwith more than 7,000 cases reported since June. The good news is that this is not a disease with a great mortality rate, being more dangerous only for pluripatological patients, which are normally those of older. The ‘war against mosquitoes’ will begin as a pilot plan. It will be From next month When the city will begin its strategy to fumigate slopes and other places that present difficulties for pest control equipment. In this way, eliminating mosquitoes (which act as virus vectors) can control the spread of the disease. This was confirmed by the Secretary of Environment and Ecology, Tse Chin-Wan, that he pointed out That the initiative seeks to relieve the load of first -line personnel, especially during the hottest months. And in the event that this first strategy works, many more robotic dogs can be deployed. Technology for difficult land. Robotic dogs, popularized by companies such as Boston Dynamics, are designed to operate and perform tasks on irregular land. Their agility makes them a viable solution to reach the habitats of mosquitoes in areas where humans cannot easily access. The potential of this technology goes beyond simple fumigation. By integrating AI, cameras and sensors, these robots can in the future detect stagnant watersmap mosquito hatcheries and send real -time updates to command centers. The AI ​​could also analyze the temperature data, rainfall and outbreaks to predict where mosquitoes are most likely to prolve, allowing preventive and more ecological action by reducing the use of chemicals. Alternatives and concerns. In addition to robots, the Hong Kong government is exploring other alternatives, such as A technique recommended by WHO which introduces a bacterium into Aedes mosquitoes to limit their reproduction capacity and virus transmission. Something that according to the authorities is already taking a result in Singapore. Robotic dogs are not free of controversies. The high cost is one of the problems that part of the population can see to this plan. In addition, there is concern that excessive dependence on technology can weaken basic preventive habits of the community, such as being careful with stagnant waters. Another critical point is The possible damage to other insects beneficial, such as bees and butterflies, which generates long -term environmental risks in pollination processes, for example. Robots begin to be present today. Apart from this idea with robotized dogs in the field of health, in China it is already organizing the Robotic Olympicsbut they are also using Robots to patrol the autonomous wind farms either even install solar parks. And having them at home is also possible Thanks to robots megatiendas that will arrive in November 2025.

The shadow of solar panels

by

Shared soil use is one of the great controversies that continue to stir in the field: many farmers Do not see with good eyes that crops live together with solar panels. However, More and more studies are and projects They show that agrovoltaic can be a real optimization for the sector. In Álava, Iberdrola wants to try it with apple trees for cider. Short. Iberdrola, in collaboration with the City of Vitoria-Gasteiz, will build a new plant agrovoltaic in Álava. This project will be developed on land assigned by the City Council within the Municipal Program “Vitoria-Gasteiz: Laboratory City”. The agricultural exploitation will be in charge of Kuartángo Sidrería, a reference in agricultural research in the province, whose objective is to boost the local apple production for cider. For its part, the 901 KWen photovoltaic plates installation has been the only agrovoltaic project selected in the Basque Country within the first call for aid to innovative renewable energy and storage projects. Panels between apple trees? As indicated Iberdrolathe project responds to a double need: produce green energy and, at the same time, improve agricultural performance. In this way, panels generate shadow over apple trees, reduce irradiation and thermal stress, protect against adverse weather of climate change, improve soil quality and reduce water consumption. Technical innovations. The installation will have several innovations aimed at optimizing both energy production and crop. An artificial intelligence software, developed by the Basque company Powerful Tree, will adjust at all times the orientation of the plates to ensure the best performance of apple trees. The modules will be located on a porticated structure of 4.1 meters high, which will allow the growth of the trees and the transit of agricultural machinery. In addition, a high -strength steel cable system will be incorporated, designed to reduce maintenance costs. The panels will be 700 W bifacial, capable of capturing solar energy on both sides, and will be accompanied by three investors with a total power of 750 kWn. The set will be completed with a 240 KWN storage system, which will offer a two -hour autonomy. The Italian mirror. The Alava bet is not an isolated experiment. This new project remembers to the Volta winery in the pugliawhich installed 7,770 solar panels in its vineyards. The results were clear: the harvest The results were clear: the harvest was delayed between three and four weeks (improving the quality of the grape), the consumption of irrigation water was reduced by 20 % and a greater balance between acidity and alcoholic degree in the wine was reached, without the need for artificial corrections. In addition, the system reduced the water stress of plants and allowed cultivating unusual varieties in the region. Not only is it agrovoltaic. The formula also works with cattle. In Nueva Wales del Sur (Australia), A study demonstrated That sheepsay of sheep under solar panels improved the quality of wool. The explanation that underlies this situation is because the shadow of the modules allowed animals to have more varied and fresh grass access, while reducing maintenance costs by acting as a “natural corteped.” Many examples, a conclusion. From the puglia to Australia and, now, in Álava, agrovoltaic is much more than an energy technology: it is a model of coexistence between the primary sector and the green transition. And it is not about choosing, as is happening in some cases by The profitability of the land. Between that black and white a third way arises: agrovoltaic. In short, the future of the field does not go on to choose between sun or earth, but to combine them. In the agrarian Spain of 2025 a hectare is no longer measured only in kilos of cereal or liters of oil, but also in kilowatts. And in Álava, apple trees that will soon grow under solar panels could become a symbol of that new balance.

The price of gold is in the clouds so that has created a new criminal business: “narcomineros”

In Stilfontein, an ancient mining town in South Africa, neighbors no longer fear the void of abandoned tunnels, but to strangers who arrive in cars loaded with rifles. “A few days come, they buy tools, they disappear,” said a local merchant. They are not traditional miners. They are armed bands that dispute, underground, an increasingly valuable booty: gold. Similar scenes are repeated in the Forests of the Amazon, in the Colombian Cauca rivers or in the tunnels of the Peruvian Andes. What was artisanal gold fever has become a silent war. The precious metal that in London or Dubai represents refuge and financial stability, in the field is stained by mercury, blood and organized crime. Goldery Fever of the 21st Century. According to Reuters estimatesthe price of gold has tripled in the last decade and rose more than 25% only so far this year. On August 21, the ounce, a historical record was quoted around $ 3.331. Amid inflation, commercial wars and geopolitical tensions, investors seek in gold which always represented: security. But that fever does not translate only into bullion in vaults. It has also unleashed a metal race in the most fragile areas of the planet. The SWISSAID NGO has counted in a report that 435 tons of gold – about 31,000 million dollars – came out of contraband of Africa in 2022, twice as much before. In Peru, the first producer of South America, the regulatory authority itself calculated that 40% of last year’s gold exports were illegal. For its part, the UN He has warned that organized crime is already embedded in global gold supply chains. “The mafias are earning more money with gold than with cocaine,” has summarized for Financial Times Sasha Lezhnev, Anntry analyst. From the subsoil to the global market. A report for Financial Times He has detailed it quite accurately, since the illegal scheme is repeated: the metal leaves an Amazonian garimpo, an abandoned mine in South Africa or a site controlled by paramilitaries in Sudan; Cross borders by smuggling or with false licenses; He arrives in Hubs like Dubai, Switzerland or India; and once molten in standard bullions, it is integrated without friction to the international financial system. In Dubai, indicated as a “washing machine” of the world gold, it is enough to pay in cash to obtain refined bars with Emiratí seal. From there they re -export to Switzerland, London or Hong Kong. A merchant He has admitted it Non -Rodeos: “We are not going to buy gold. We acquire it in the wholesale market, we give the money and receive it. No one asks where it comes from.” Modus Operandi Global. On the one hand, in Latin America, groups such as the Gulf clan in Colombia or the PCC in Brazil already operate mines and dredgers. In Peru, almost 40 workers have been killed in deposits. On the other hand, in South Africa, the calls Zama Zamas They work under the control of mafias in abandoned mines, where authentic underground wars are fought. In Sudan, gold finances the RSF militia, accused of atrocities in the civil war. Logistics remembers drug trafficking: clandestine flights, improvised clues, corruption networks. With a crucial difference: while cocaine is always illegal, gold is legalized at the moment it merges into a ingot. The consequences are devastating. According to FTMercury poisons Ríos del Amazonas, fauna disappears and communities such as Yanomami suffer hunger, malaria and violence. “When the Garimpo arrives, diseases and drugs arrive,” explained the indigenous leader Juarez Saw. In South Africa, entire villages survive around ghost mines, trapped between poverty and violence. And in Sudan, gold has become a fuel of a civil war that already adds more than 150,000 dead. Governments against the strings. States try to react, with partial achievements. In Brazil, the Lula Government destroyed camps In the Yanomami Earth and boasts a 98% drop in illegal mines there and 40% less in gold exports. But the miners return when the operation ends. In South Africa, the police cut access to tunnels, without stopping the power of the mafias. In Sudan, international pressure has forced Dubai to harden purchase controls, although in his gold of gold there are still ingots of uncertain origin. The pattern is repeated: local corruption, territories impossible to monitor and criminal networks better financed than the states themselves. The formal market, innocent? The legal circuit is not alien either. The London Bullion Market Association (LBMA) sets global standards, but is a private club and traders club. Its liquidation system concentrates world trade without public supervision. The European Central Bank warns that the opacity and concentration of the gold market represent a risk for global financial stability. Bernhard Schnellmann, former director of the Swiss Refinery Argor Heraeus, He has synthesized it in his opinion column for FT: “Gold is too important to leave it in the hands of private clubs.” The new oil of the crime. The gold, eternal symbol of wealth and security, is today the new oil of the crime: a resource that feeds mafias, destroys jungles and finances wars. For investors in London or Dubai it is an active refuge. For clandestine miners in the Amazon or South Africa, it is a promise of escape that often ends in violence. In the vaults, a 400 -ounces ingot is identical regardless of its origin. But behind each bar can hide rifles, malaria, corruption and poisoned rivers.
