Openai has invested billions in chips. His only problem is that he has forgotten something important: cables

by

While Openai designs increasingly complex models and promises cities size data centers, a much more terrestrial reality threatens to stop the advance: the electrical infrastructure is not ready for what is coming. At the beginning of the year. Sam Altman (OpenAI CEO) promised, together with Oracle and SoftBank, an investment of 500,000 million dollars in AI infrastructure Under the name Stargate. The announcement, Made at the White House with President Trumphe talked about building 10 gigawatts of data centers on American soil by 2029. However, the start has been slower than expected. According to The Wall Street Journalnot a single formal contract with SoftBank has not been signed, and the first center, in Ohio, is still in the evaluation phase. Meanwhile, Openai has advanced on his own, expanding his alliance with Oracle to develop 4.5 more gigawatts, adding more than 5 GW under construction, As the company itself has reported. A big problem behind. This does not only affect Openai, rather the entire AI sector since no investment or quantity of GPUS can solve the true bottleneck of the sector alone: the electricity grid. As Le Monde explainedtraining models such as GPT-4 consumes dozens of gigawatts -hora, but the real challenge is in the “inference”, that is, in daily use. Each consultation to a model like Chatgpt implies complex calculations that consume energy every second. From the International Energy Agency (IEA), It was warned That the global electricity consumption of data centers could double before 2030, exceeding 945 TWH, more than all Japan today. And there the paradox appears: we can generate more energy, but we have no how to move it. In other words, high voltage lines, transformers, substations, adequate land, permits, technicians are missing. It’s like wanting to fill a city with bottled water, but without having pipes. The project continues. In a last statementOpenai has affirmed that its expansion with Oracle is already creating tens of thousands of jobs in Texas and that the objective of the 10 gigawatts is on its way to being surpassed thanks to new alliances. The Stargate I site, in Abilene, has already begun to operate with NVIDIA GB200 chips. However, As the Wall Street Journal has detailed, Disagreements with SoftBank persist on where to build, how to finance and how to connect data centers to electrical networks that are already saturated. Sam Altman recognized the challenge in an internal memorandum cited by axios: “The thirst for computer science is beginning to tension the supply chain and demands some real creativity.” Other paths: atomic energy. Faced with these limitations, technological giants are looking for solutions outside the traditional electrical system. The answer, for many, is in a surprising return: nuclear energy. Goal has signed a 20 -year contract with Constellation Energy to supply part of its data centers from a nuclear plant in Illinois. Google and Amazon They have also opted for small modular reactors (SMR). Microsoft, meanwhile, will reopen a closed nuclear power plant since 2019exclusively to support your AI infrastructure. Nvidia has not been left behind. In 2024, it invested 650 million dollars in Terrapower, the company founded by Bill Gates that is building the first Natriat reactor, a fourth generation machine that, According to their developersIt will generate electricity by half of the cost of a conventional reactor. The project, which takes place in Wyoming, has a Spanish participation: the public company sees the reactor cover. Without cables, there is no ia. Meanwhile, the number of users continues to grow. Chatgpt reached 800 million active users in April, According to Altman cited in axios. Each of them generates requests, questions, images, instructions, and all that consumes energy. According to Le Mondetasks as simple as writing an email can be more than 7% of a complete mobile phone charge. And generating an image consumes even more. Elon Musk says his company XAI already operates with 230,000 GPUS, and expects 550,000 more. The AI does not rest, but the cables that feed do not supply. Artificial intelligence promises to change the world, but before it will have to face something more basic than any algorithm: the physical laws of electrical systems. There is no needless. There are no servers without energy. And there is no energy without cables.

The ruins of a temple located in the Andes can rewrite the history of a forgotten pre -Hispanic civilization

by

It is possible that the name Tiwanaku does not sound too much. It is not among the great most famous pre -Hispanic civilizations such as the Incas, Aztecs or Maya. However, this missing society before Europeans arrived in the South American continent reached unique dominance of their surroundings. The last discovery is proof of this. More than 200 kilometers. A team of researchers has documented A temple built by the civilization of Tiwanaku. This temple was found about 210 kilometers south of the power center of this civilization which allows us to better understand the geographical extension of the domain of this pre -Columbian culture. The state of Tiwanaku. There is little we know today about Tiwanaku. This civilization would have emerged south of Lake Titicaca, in what is now Bolivia. Tiwanaku would have managed to be one of the most powerful civilizations on the continent, but disappeared around the year 1000 of our era,, giving rise to the arrival of the Incas that would dominate the region five centuries later. This civilization would have achieved, Explain the responsible team of the new discovery, an advanced social structure and left behind traces of its architecture in the form of pyramids, staggered temples and monoliths, distributed in the vicinity of Lake Titicaca. However, delimiting the area of ​​influence of Tiwanaku is difficult among those who study this civilization. The last discovery can be helpful. The Palaspata temple. The site was baptized as the Palaspata temple in reference to the name by which the natives call in the area. As described, these ruins show a rectangular complex with 125 meters long and 145 wide. I would have had 15 quadrangular enclosures and an inner courtyard. The temple disposition would not have been random since it is aligned with the equinox. In the enclosure, fragments of Keru glasses were found, which were used for chicha consumption, a corn beer. Corn is not a local crop so The team considers that Palaspata’s environment would have been a commercial node in the Tiwanaku civilization. Combining techniques. To study the diffuse brands left by the old temple the team had to combine different satellite images, images that combined with those taken by drones with those who fly over the site. They also resorted to the photogrammetry technique, that is, three -dimensional reconstruction from multiple photographs. The details of the study were published In an article In the magazine Antiquity. Recycling the stones. Although we have just discovered the nature of this archaeological site, the environment was well known by local people. In fact, some of the stones and artifacts that constituted this temple had been “recycled” by local farmers in their own constructions. A triple border. Palaspata’s significance lies in its location as we indicated at the beginning, a “strategic” location for those responsible for the finding. This area, they explain, connected three of the main trade routes that communicated three valleys with two ecosystems: the high and fertile lands next to Lake Titicaca; The Andean Altiplano, livestock zone where the flames grew; and the Andean valleys east of Cochabamba, another agrarian region.

It is possible that your gmail is destroying the emails that arrive and do not know. The fault is for forgotten adjustment

by

Dozens of readers of The country They complained that some of the Newsletters received contained “rude errata”. Meaningless phrases, words that seemed terribly chosen … When doing the checks, the technical team of The country realized that Newsletters They did not contain those errors, the writing was adequate. But in the receptor mailbox they were modified. Why is it important. The ruling was not in the newspaper, but in Gmail. Those who protested had activated the automatic translator into Spanish, so that any mail received was seen in this language. The problem is that this translator acts even in mails that are already in Spanish, turning words when detecting English where there was no. Where he put “secret military plans”, appeared “Airplanes Secret military “. Where he put “Trump uses the power of the State to blackmail institutions”, appeared “Trump uses the power of the State to sing to institutions “. The context. Gmail is The most used mail service in the world, and many users have activated their translator “always translate automatically.” This function, as we have seen, operates even about texts already written in your language. Between the lines. What began as a sum of readers complaints has exposed a much greater problem: platforms can alter content without anyone knowing, at least for a while. The issuer sends a message, the receiver reads another, and none suspects that there is a tool in the background by modifying words. The threat. If Gmail can change “siege” by “seminar”, another of the examples cited by the newspaper, can also introduce intentional biases. Or forced. For example, a government order can force automatically replace “Gulf of Mexico” by “Gulfo de América” In all emails. Users would read it and normalize without knowing that the content has been manipulated. Yes, but. This automatic customization is born from a good idea, is born from helping. The problem comes when the help becomes invasive, is not entirely well designed (no anglicisms in Spanish from homonymous words between languages) and is opaque. Nothing made those affected think that the fault came from there. It does not seem fair to trust years of use of a tool to which at the time the user activated it or granted certain permits if nothing that happens later acts as a subtle reminder. In the foreground. For the first time, readers were not reading what journalists had written. And neither the first nor the second were aware of it. It is the symptom of an era where sometimes machines make decisions about the information we consume without transparency or real control.

The glaciers are the great forgotten fresh water reserve of the planet. And we are running out of it

by

According to estimates From the United States Geological Service (USGS), glaciers, along with the permanent ice layer and snow, house more than 24 million cubic kilometers of water. This represents 1.74% of the total water on the planet, but also 68.7% of fresh water. The risk of losing these reservations is growing. 273,000 million tons. A new study in which the European Space Agency (That) has revealed the rhythm at which the glaciers of our planet have been losing water since 2000. The figures are not hopeful: our glaciers have lost 273,000 million tons of water per year on average. “To put this in perspective, the 273,000 million tons lost annually represent what the world’s population consumes in 30 years, assuming (a consumption of) three liters per person and day,” Indicate in a press release Michael Zemp. Another way of seeing it in perspective is to take into account that the glaciers of this planet, according to the agency itself, contained approximately 121.73 billion tons of ice. During the last decades the glaciers have seen a 5% drop in their volume. In crescendo. The team has also warned that the rhythm at which we lose ice has been growing throughout the study period. The study covered the period between 2000 and 2023 and was divided into two subperiods: 2000–2011 and 2012–2023. Comparing both periods the team found an acceleration in the rhythm at which glaciers lose water: in the second period the loss of ice was 36% greater than in the first. The geographical context also matters. If we previously indicated that, globally, the glaciers had lost 5% of their volume, regional losses are among 2% observed in the Antarctic and Subantarctic Islands, and 39% loss of volume observed in Central Europe. The image shows diversity in the portion of lost glaciers in different regions. ESA/Planetary Visions GLAMBIE. The investigation has been carried out within the framework of the Glambie project (Glacier Mass Balance Intercomparison Exercise), An initiative of the WGMS (World Glacier Monitoring Service) of the University of Zurich in collaboration with the University of Edinburgh and the Earthwave company dedicated to estimate the global ice mass lost by the glaciers. The initiative generated a temporary series for the study period (2000-2023) combining data from different sources. Among them they used satellite observations of the Aster instrument aboard the American Mission Terra and ICESAT-2also from NASA; in combination with data obtained from European and Euro -Eastern Missions Grace, Tandem-X and Cryosat. The details of the study have been published In an article In the magazine Nature. It is not just sea level. This loss of ice has a well -known plenty of involvement: the nearly 6.55 billion tons of disappeared water from the glaciers have ended melted in the sea, which, according to equipment estimates, has contributed to the increase in the level of the waters in about 18 millimeters, about 0.75 mm per year. However, although the increase in sea level is often the “visible face” of climate change, the problem goes further. And it is that glaciers are an important water reserve. Its thaw contributes significantly to the flow of many rivers. This is the case of the Ebro, which feeds on the glaciers of the Pyrenees in addition to the thaw of mountains in the Cantabrian mountain range and the Iberian system. “Glaciers are a vital source of fresh water, especially in local communities in Central Asia and the central Andes, where glaciers dominate runoff during warm and dry stations,” also explains in the press release Inés Dussaillant, co -author of the study.

Huelva has been the forgotten industrial pole of Spain for decades. We are realizing the consequences

by

Industrial and miners are a problem in different points of our geography. It is still a problem in places where deindustrialization left hectares of empty but contaminated soils and is a problem in the vicinity of some active industrial poles. And one of the places where this is most appreciated is in the estuary of the Odiel and Tinto rivers, on the coast of the province of Huelva. As, PB, CD, MO, SE. A new study He has found evidence that people who live in the vicinity of Huelva industrial areas accumulate in their bodies amounts higher than the average heavy metals such as those we usually associate with industrial activity. The study observed that among the inhabitants of the region, the accumulation in the body of certain elements was greater than usual. The study was done In the city of Huelvabut it was observed that the pollutants varied depending on the residence area of ​​the participants. Different concentrations. Among those who lived in areas closer to the rafts of phosphoyesos From the region, the study found a greater presence of elements such as arsenic (as), lead (PB), cadmium (CD), molybdenum (mo) and selenium (se). These types of elements can be found, precisely in places where this type of waste is stored. On the other hand, the team also found areas that stood out for the presence of elements such as copper (cu), zinc (zn) and aluminum (al). These areas were the closest to the industrial area of ​​the region. In general, the inhabitants of the city of Huelva presented greater concentrations of iron (faith), nickel (ni), chromium (cr), selenium (se), arsenic (as), and copper (co) according to the results of the study. The “chemical and industrial pole. The study was conducted in the city of Huelva, a city located near the coast, between the confluence of the red and odiel rivers. The city counts around, explains the team responsible for the study, with three important industrial areas. First, phosphoyesos rafts can be found, an industrial residue resulting from the extraction and processing of phosphoric acid. This residue is categorized as a radioactive material that occurred naturally or norm (Naturally Occurring Radioactive Material) and the Huelva reserve is the largest in Europe, the team recalls. To this we must add two more conventional industrial areas, the “Chemical Pole for the Promotion and Development of Huelva – Punta del Sebo” and the “Nuevo Puerto Palos de la Frontera”. Both areas also located in the vicinity of the capital (being the first adjacent to it). 55 participants. The study was conducted with a little girl from participants residing in the capital. Samples extracted from the feet nails of these to estimate the concentration in the bodies of a series of elements: aluminum (al), arsenic (as), cadmium (CD), copper (cu), chrome (cr), iron (faith), nickel (ni), Uranium (U), Vanadio (V) and Zinc (Zn), among others. The details of the study were published In an article In the magazine Journal of Xenobiotics.

The Galaxy S25 have forgotten the best technology of the year

by

A sublime integration with Geminiinteresting news in the photographic section, the more powerful processor of the industry and a new design that we had been waiting for years for the most advanced model. These are some of the improvements that have made the Unpacked 2025 and that Samsung has shown as the main assets to buy one of the new Galaxy S25, S25+ or S25 Ultra. But, like everything in this life, you cannot get everything right in each section, and There is one that the Korean company has completely forgotten about. What is the great lack of the Samsung Galaxy S25? The battery. The company has not moved a single figure from one year to the next, and maintains the same mAh in each of the models. The design and dimensions hardly change in the new devices – beyond the new Ultra – which could justify the lack of news in this section. Samsung has gone too far when it comes to talking about its batteries, autonomy and fast chargingimplying that it is a section without much room for improvement. Is this true? Are there any relevant milestones in the industry? Has Samsung been left behind? The Galaxy S25 forgets the most important novelty in the battery industry in recent years We are not exaggerating in the slightest. During the last quarter of 2024, the battery industry—specifically those for mobile phones—has achieved a very relevant milestone: the marketing and distribution of silicon-carbon cells. Not only are they fully developed, but there are already several smartphones on sale that integrate them. A good example is the Xiaomi 15a device that was presented in China a couple of months ago with a increase of almost 900 mAh compared to the previous generation. The most interesting thing? Its thickness has only increased by 0.1 millimeterspractically nothing. All thanks to the higher energy density of silicon-carbon. Even much more modest models are betting on this technology. In the mid-range is the Honor Magic7 Litea newcomer to Spain that we have been able to test and that boasts of 6,600 mAh in a 7.98 millimeter body and 189 grams of weight. To put this data in perspective, the Galaxy S25 Ultra has a 5,000 mAh battery that is 8.2 millimeters thick. With these figures on the table, it is impossible not to think that Samsung has missed a good opportunity to make a difference. Opting for silicon-carbon batteries in the Galaxy S25 series would have been a true revolution and a very important leap compared to the previous generation. Only time will tell if Samsung is wrong with this decision, although one thing seems quite obvious: the competition, especially that which comes from China, wants to revolutionize autonomies by 2025 and make mobile phones with huge batteries that are not limited by a thicker or heavier design than normal. It’s a shame that Samsung hasn’t jumped on this boat. Fast charging, but not too fast This 2025 we not only have identical batteries to the 2024 generation, also a fast charge that does not move a single watt (W). Samsung is once again betting on 45 W in the Galaxy S25+ and S25 Ultra, while at the bottom of the list is the Galaxy S25 with a power of 25 W. It is another section that leaves us with a bittersweet taste. Samsung and Apple are fighting a lonely battle for slow fast charging, and while the market is not asking for abysmal 200W powers, it is supporting brands that choose to raise the level a little and allow 80 or 90 W recharges. The figures of the new mobile phones, without being considered slow – the 25 W of the Galaxy S25 yes, everything must be said – They are at the bottom of the industrysomething that does not quite add up when we talk about three mobile phones that intend to reign in the high-end for much of 2025. The Samsung Galaxy S25 are great devices, they come with a good dose of AI, several of the best cameras of the year and unparalleled power for gaming, but they have not managed to finish off and justify the generation step when we talk about battery and fast charging. Using silicon-carbon would have been the culmination, but Samsung wanted to reserve this technology for later.
