why the USSR was obsessed with a planet that literally ate its machines

by

There was a time when it was thought that Venus would be a good planet to explore or even terraform. After all, it is close to Earth. Carl Sagan himself made a theoretical proposal to adapt this planet for human life. Therefore, it is not surprising that it became one of the biggest objectives of the Soviet Union (USSR) during the beginning of its space race. With the Venera missions, dozens of probes were sent to explore the neighboring planet. A few were enough to prove that it was a more inhospitable place than one thought. However, that did not make those scientists give up their efforts. Only 16 named probes. Between 1961 and 1984, The USSR sent 28 probes to Venus. Only 16 of them, those that partially completed their mission, were baptized as Venera. Of those 16, only 13 crossed the atmosphere of the neighboring planet and 10 managed to land. Some even survived a few minutes to transmit important information to Earth. The violent destruction of each probe provided new data that was used to improve the next one. Even knowing that the next one would also succumb, the program continued forward and laid the pillars of the space exploration technologies that came later. An inhospitable planet. Venus It is an extremely inhospitable planet for many reasons. To begin with, its temperatures are very high. Temperatures can reach 465ºC, which is why many Venera probes literally melted when they reached their destination. The pressure is also very high. It is equivalent to about 90 atmospheres and could quickly crush a submarine. Many of these probes were also crushed. On the other hand, more than 96% of its atmosphere is carbon dioxide, making it highly toxic, although that is not as problematic as the corrosive clouds of sulfuric acid that accompany it. The Venera probes also had to deal with this corrosion. step by step. The first Venera probes lost communication with Earth before even reaching Venus. Others, however, managed to transmit information from the surroundings of the neighboring planet or even on its surface. The first to send data before being crushed by the pressure were Venera 5 and Venera 6. Previously, Venera 4 had been the first probe to manage to pass through the atmosphere of a planet other than Earth. Venera 7 even managed to land and stay 23 minutes on the surface of Venus before being torn apart by the heat and pressure. Later, Venera 9 sent the first black and white images. Images of the surface of Venus taken by the Venera probes Special mention to Venera 13. Possibly the greatest advances came with Venera 13. Although it was planned to last 32 minutes, the probe stayed on Venus for 127 minutes before disappearing like all the others. There he managed to take photographs much more advanced than those of Venera 9. He also measured the composition of the atmosphere and used a lightning detector to measure the electrical activity of Venus. It was even able to analyze the winds thanks to its built-in anemometer. Along with Venera 14, it was possibly the probe that provided the greatest discoveries before disappearing like all the others. 40 years later. With the Venera missions, the USSR verified that, in reality, Venus was a planet too inhospitable for exploration. But knowing our neighbors can help us know ourselves. For this reason, despite knowing that it was all suicide, 28 probes were sent, with landing, chemical analysis or image taking technologies that have continued to be used over time. Today, more than 40 years after the launch of the last probe, we can access the data obtained by many other missions that have also headed to Venus. Other missions. First it was NASA, in 1970, with its Mariner 10 probe. Although its main objective was Mercury, it also had time to explore the surroundings of Venus. Later in 1989 The Magellan mission made the first global map of the Venusian surface. Today the American agency is preparing for the launch of VERITAS and DAVINCI+, which should leave for the neighboring planet in the coming years. For its part, Europe launched the Venus Express probe in 2005 and Japan launched the Akatsuki probe in 2010. In the next decade, Europe is prepared to launch Envision, which will be in charge of studying the core of the planet. All of these missions were clearly inspired by the Venera probes. Of course, even if we can never live there, being able to send probes to a planet that melts and crushes ships is a great achievement of space technology.

Iceland was one of the last places on the planet that mosquitoes had not reached. That’s now history

by

For centuries, Iceland has held the ‘privilege’ of being one of the few habitable places on Earth where mosquitoes did not exist, something that can be a source of envy for many, especially with the arrival of summer. All thanks to its particular climate, with constant cycles of freezing and thawing that prevented the larvae from maturing, it acted as an insurmountable biological shield. However, climate change and human action have just broken down this barrier and this Icelandic ‘exceptionality’ has ended. The discovery. The history of this biological invasion starts in October 2025where Björn Hjaltason, a resident of the Kjós region noticed the presence of some unusual insects in his garden. From there he wanted to see them closer, and to capture them he used a fairly rudimentary method based on some ropes soaked in red wine. With this trap he obtained three specimens that were immediately sent to the Icelandic Institute of Natural Sciences, where the entomologist Matthías Alfreðsson confirmed the unthinkable: they were two females and a male. Culiseta annulataa species of mosquito common in Europe, but which had never managed to establish itself on the island of ice and fire. How have they arrived? Their disembarkation in the country may have been conditioned to different situations, such as travel aboard ships that came from Europe or even in the landing gear of commercial airplanes. All this, added to increasingly higher temperatures in Iceland, means that we are facing a major ecosystem problem. A hot Arctic. This very rudimentary discovery has served as a substrate for a profound analysis that has been published in the magazine Science, where it is noted that the appearance of mosquitoes in Iceland is only the symptom of a radical transformation throughout the Arctic. And global warming is affecting this region at breakneck speed, since the Arctic is warming four times faster than the world average. This thermal increase is not only allowing invasive species to survive the Icelandic winters, but is causing a serious biological imbalance throughout the boreal region. A domino effect. The arrival of mosquitoes and the alteration of the populations of native arthropods is not only a problem of annoying bites for its inhabitants or tourists, but it is a threat for birds. Here the early thaw is causing the peak of insect abundance to no longer coincide with the breeding season of waders, leaving them without their main source of food when they need it most. Furthermore, the large swarms of mosquitoes in arctic areas are already affecting the behavior of reindeer, which spend vital energy fleeing from the swarms instead of feeding, compromising their winter survival. That is why experts point to the need to control the arthropods that arrive in the region and, above all, a tracking system for these ecological changes that are so relevant.

The rarest and rarest feline on the planet has found the nail in the coffin that was missing: the war in Iran

by

He asian cheetah (Acinonyx jubatus venaticus) is one of the rarest and most endangered subspecies of big cats on the planet. There are only 27 individuals left at large, all of them are identified one by one and all of them live in Iran, as explains Bagher Nezaminational director of Asiatic Cheetah Conservation Project. There is no other known population anywhere else on the planet. In serious danger of extinction, what was already a critical situation has become an emergency since the attacks by the United States and Israel in Iran began in February 2026: the war has paralyzed the only monitoring system that kept this subspecies under control. What is happening with the Asian cheetah. As account the environmental science and conservation news platform Mongabay, just nine days after forest guards filmed a female with five cubs in the province of North Khorasan, the armed conflict began. Since then, access to the reserves where these animals live has been drastically restricted. The risk is not so much that a bomb falls on a reserve, but rather the lack of vigilance. The field vehicles used by field scientists and park rangers to guard the small population of Asiatic cheetahs can be mistaken for military targets in their scattered habitat (especially in the desert), so many of Iran’s environmental NGOs have stopped their activity. The country also suffers an internet blackout. This means that monitoring, field studies and field use are no longer operational. The species. The Asian cheetah diverged from African populations between 32,000 and 67,000 years ago. It is not an African cheetah implanted in Asia, but rather it has its own evolutionary lineage: it is smaller and has lighter fur than the African one and is adapted to arid areas and mountainous terrain. In fact, its monitoring is more complex not only because there are few of them, but because it lives in inhospitable areas. In any case, both are true Ferraris: they can exceed speeds of 100 km/h in short races. The IUCN has it classified on the Critically Endangered conservation scale since 1996, the highest alert before extinction in the wild. From an ecological perspective, it serves as a specialized predator on medium-sized ungulates—mainly gazelles—in the desert ecosystems of central Iran. Their disappearance could not be compensated by introducing African cheetahs: the genetic, physiological and behavioral divergence between both groups is too great and hybridization proposals do not have scientific support as a viable short-term solution. Why is it important. Because it is not a rare subspecies of a known felid, but rather it has a genetically differentiated lineage and is native to Asia. It has more than 30,000 years of history independent of African populations and its disappearance is not compensated by introducing African cheetahs. Furthermore, it fulfills its function there: it is a specialized predator on medium-sized ungulates in the arid ecosystems of central Iran, thus maintaining the balance of gazelle populations. In short: it has its place in the food chain of the desert ecosystem in the interior of the country. The situation of the Asian cheetah is also a direct indicator of the state of biodiversity conservation at war, as pointed out this article in People and Nature: its consequences are suffered decades after the conflict and sometimes, they are simply irreversible. Iran is home to exceptional biological diversity: Persian leopard, brown bear (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolf (Canis lupus), among others. The collapse of the cheetah conservation system irremediably affects the rest. Context. Since 1959, the Asiatic cheetah has had legal protection in Iran. In the following decades its population was stabilized, but the Revolution of 1979 and the Iran-Iraq war of the 1980s they were wasted years: Lax law enforcement wreaked havoc in the form of zero patrolling, destruction and fragmentation of their habitat, uncontrolled hunting, and decline in prey. In January 2022, Hassan Akbari, deputy minister of natural environment and biodiversity at Iran’s Department of Environment, declared that the Asiatic cheetah population had plummeted to just 12, down from an estimated 100 in 2010. In August 2025, the Tehran Times reported that only 20 copies remained. Monitoring them is very complicated per sebut there are also circumstances that work against it. For example, the controversial use of camera traps: in 2018 several people from Persian Wildlife Heritage Foundation accused of using camera traps for espionage. One person died in prison and the rest were pardoned in 2024. This case paralyzed international collaboration for years. In addition, Western sanctions have also systematically prevented the arrival of financing, essential for adequate monitoring. Asiatic cheetah dies. The main cause of death for Asian cheetahs is not poaching or predators, but the road. More than 52% of documented deaths They are due to accidents on roads that cross or border key habitats and cheetahs cross them without fear and repeatedly following their prey, such as Abbasabad-Mashhad and Mehriz-Anar. There are a couple of especially notorious cases of females run over, pregnant or with their young, in recent years: Meyami and Helia. Since the beginning of the conflict, these roads now also transport military material and people for evacuation, which increases traffic. With 27 individuals registered, there is no longer room for errors or unsupervised times: genetic analysis published in Conservation Genetics details that genetic diversity is critically low and inbreeding poses an additional risk to the viability of the subspecies. What can be done. Wild Tomorrow analyzes this problem in detail, advising to ignore social media campaigns that call for “emergency evacuations” without rigor: moving big wild cats across militarized borders is medically risky and informal channels can prove to be a route for illegal trafficking. Furthermore, we have already seen that proposing clandestine communications can expose those who protect the cheetah to accusations of espionage. What does have a real effect is supporting the Iranian Cheetah Society, the organization with the greatest field knowledge of this population. Likewise, at the international level there are organizations with real capacity … Read more

We thought we were 8 billion people on the entire planet. Until some researchers started crunching the numbers

by

In November 2022, the UN celebrated that we were now 8 billion humans on Earth. They are estimates, of course, but beyond the figure, the really interesting thing is that in 2023 we do not reach the replacement rate and that humanity will reach its peak at the end of the century to, inevitably, start to fall. But… to what extent can we trust these accounts? It is something that has been on the table for some time and, according to a study of 2025, we have made a mistake in counting. So much so that we have left several hundred million people behind. Can we trust the numbers? “Calculating the number of people on the planet is an inexact science.” That was demographer Jakub Bijak’s comment to BBC in mid-2024, just when the World Population Prospects study. Something scientific is something exact, but the researcher also commented that the only thing you can be sure of when predicting population figures is the lack of certainty. That, be careful, does not mean that demographers take figures out of thin air. “It is a difficult thing based on our experience, knowledge and every piece of information we have access to,” said Toshiko Kanera, an expert in demographic forecasts. Demographers draw on the data and trends of each country since 1950, but… what if it had not been counted correctly? We are missing millions. In a 2025 study published in Natureresearchers at Aalto University in Finland show how the data sets handled by demographers “profoundly and systematically” underestimate population figures around the world. The serious thing is that we would be talking about hundreds of millions more people living on Earth. Example of the tools that demographers use in their analysis. Each one corresponds to a different bias Rural areas. Josias Láng-Ritter is one of the researchers in charge of the study and points to the accounts carried out in a specific segment: that of rural population. “For the first time, our study provides evidence that a significant proportion of the rural population could be missing from global population data sets,” he notes. As we say, we are not talking about a few million, but billions. “Depending on the data set used, rural populations have been underestimated between 53% and 84% in the period studied. The results are notable, since these data sets have been used in thousands of studies and have widely supported decision making, but their accuracy has not been systematically evaluated,” comments the researcher. The map shows the location of the 307 rural areas analyzed in the study. The populations reported in the graph were found to be underestimated by between 53% and 84% | Aalto University Biases. Attempts to review this data are not new, but previous research has focused on specific countries or urban areas. Researchers from Aalto University wanted to give a more global picture by comparing the five most used population data sets worldwide. They have used maps that divide the planet into high-resolution grids and have taken something very specific as a reference: resettlement figures from more than 300 rural dam projects in 35 countries. Why this bias of the dams? Because when a dam is builtthe population that lives in the area that will be flooded is relocated and accurate resettlement data is usually available. Comparing that population data from 1975 to 2010, the researchers found that the 2010 maps were more accurate, but still left out between 32% and 77% of the rural population. Between 2015 and 2020 the data sets were updated, but demographers continue to believe that underestimation of the rural population continues to exist and is a problem that persists in all regions of the world. Consequences. And we are talking about a problem whose resolution is complex. According to the researchers, no matter how much the data is reviewed, it is a structural problem. Governments do not have the resources to collect accurate data in these rural regions, there is a huge discrepancy between the real population and that reported on the population maps used to carry out demographic studies and that influences decision making. Average percentage of rural population underestimated (red and orange) and overestimated (blue) | Aalto University And it’s important. Current estimates place 43% of the 8.2 billion inhabitants of the world in rural areas -about 3,526 million people- and if we take into account that it is a percentage that has been underestimated between 53% and 84%, we are not talking about a small population, precisely. And it is essential to know exactly how many we are for a simple reason: the redistribution of resources. No data. The lack of accurate demographic records can affect political decision-making. Ritter gives the example of social decisions. “In many countries, there may not be enough data available at the national level, so they rely on global population maps to support their decisions: Do we need a paved road or a hospital? How much medicine is needed in a specific area? How many people could be affected by natural disasters like earthquakes or floods?” he says. Doing quick math, in the best scenario – that of 53% deviation in the rural population – we would be talking about 1,869 million people who would not have been counted. In the worst case, in that of the 84% not registered, we would talk about 2,962 million people. In the Nature study, they give the example of Paraguay, which in the 2012 census may have left out a quarter of the population. Reviewing the methods. In the team’s analysis, there are countries that fare better than others. They point to Finland as an example of reliable data, even in rural regions, because they began keeping digital records of the population 30 years ago. However, in countries where this thorough digital registration has taken longer to be implemented due to crises of any kind, the differences between the real population and the estimated one can be significant. “To provide rural communities … Read more

This planet is too big for its star. When we tried to find out the reason, we found something even more disconcerting.

by

The universe is so immense that it should not surprise us that it is full of exceptions. But even so, there is still such disconcerting findings that obsess astronomers. This is, for example, the case of TOI-5205 b, an exoplanet that attracts attention due to its size, too large for its star. That alone would be truly exceptional, but a new study has found that, if that were not enough, it also has a very unusual atmosphere. Too big for a red dwarf. TOI-5205 b is a gas giant, slightly larger than Jupiter. But only a little. While Jupiter orbits the Sun, this exoplanet orbits a red dwarf. That is, a relatively cold and very small star, with a mass ranging from 7.5% to 50% of the mass of our Sun. Typically, stars are MUCH larger than the planets that orbit them. However, the radius of this red dwarf is only four times that of TOI-5205 b. To continue with the comparisons, our Sun has a radius approximately 10 times larger than that of Jupiter. And it’s not just a radio issue. The mass of this exoplanet is also striking, as it is equivalent to 0.3% of the mass of the red dwarf. Jupiter’s mass is approximately 0.095% of the Sun’s mass. All this tells us that TOI-5205 b is too big for its star. An even more disconcerting clue. Recently, a team of scientists from NASA and the Carnegie Science Institute decided to study the composition of the atmosphere of TOI-5205 blooking for clues about its origin that explain why it is so big. However, what they discovered was even more disconcerting. They carried out the analysis of the atmosphere studying the transit of the planet. That is, analyzing the changes in the light of its star when the planet passes in front of it. When light interacts with the planet’s atmosphere, it interacts with the molecules found in it. Each element reflects light in different bands of the electromagnetic spectrum, so, with the help of a spectrograph, you can know which elements the light has interacted with and, consequently, what the composition of the atmosphere is. Astronomical metals. For astronomers, any element other than hydrogen or helium is considered a metal. Just for them, chemists don’t like this. The point is that this decision the concept of metallicity arises. It refers to the proportion of metals that a planet or star has in its atmosphere. When a star forms, it is assumed to take most of the hydrogen and helium present in the stellar nursery with it. Therefore, when a planet later forms around it, it is normal for its atmosphere to have a higher proportion of metals. For this reason, it is said that the metallicity of the planets is higher than that of their stars. But with TOI-5205 b that does not happen. According to analyzes of its transit, its metallicity is lower than that of the red dwarf. hidden metals. To verify what this phenomenon is due to, the authors of the study that was recently published carried out a series of mathematical models. With them, they wanted to check how the atmosphere of this exoplanet could have evolved under different scenarios. This allowed them to verify that the current situation is consistent with their metals having been buried inside the planet. It is true that when it was formed absorbed a greater amount of metals, since the star had taken more helium and hydrogen. However, these metals did not remain in the atmosphere, but were they saved inside TOI-5205 b. In the atmosphere, however, there is some helium and hydrogen, but also other compounds, such as methane and hydrogen sulfide. What this exception teaches us. As explained in a statement One of the authors of the study, Anjali Piette, “these findings have implications for our understanding of the process of giant planet formation that occurs early in the life of a star.” Sometimes, it is the exception to the rule the one that can provide us with the most data. There’s nothing like thinking outside the box. Image | Katherine Cain (Carnegie Science) In Xataka | Since we were children we have been told that Jupiter is enormous, colossal, exaggeratedly large.

OpenAI is the most successful company on the planet. Also the one that plans to lose 85,000 million dollars in a single year

by

Something special is going to happen in 2026: both OpenAI and Anthropic are going public. This will finally mean that individual investors can invest in them and bet on their future with their money. It will be the definitive exam for the credibility of companies that have grown exceptionally in recent years but also They have burned the money as if there were no tomorrow. But be careful, because there is a compelling reality here: they are going to continue burning it in an even more astonishing way. The two sides of the IPO. The Wall Street Journal has had access to the financial documents submitted to investors before the IPOs proposed by both OpenAI and Anthropic. They reveal extraordinarily striking data that have two sides. Amazement and concern with OpenAI. For example, OpenAI has indicated that it will almost double its revenue this year. According to their forecasts, they could become profitable in 2026 if one excludes the cost of training their models (which are stratospheric, of course). But there is the other reality: OpenAI expects to spend $121 billion on computing power in 2028, so even doubling revenue it will lose, attention, $85 billion. No company has ever lost this amount of money and survived, but OpenAI not only promises that it will survive, but that those losses will end up being almost anecdotal. I tell you the truth, but only part of it. Both companies wanted to show two different versions of reality when talking about how they present their profitability. In one, the very expensive model training processes are included, and in others in which these costs are excluded under a heading called “computing for research.” Excluding those costs, OpenAI is on track to achieve a small pre-tax operating profit this year. Anthropic also promises to achieve this if its most optimistic scenario comes true. Excluding the cost of training models, both OpenAI and Anthropic could be “profitable” this year. Source: WSJ. Until 2030, no real profitability. If the costs and investment in model training are included, OpenAI indicates that it will end up being profitable in 2030, a fact that They had already planned a long time ago and that could not hide a forceful reality: the company has not only not stopped spending money until now: it is going to continue spending it, but to an even greater extent with projects like Stargate to the head. Saying that in 2026 they will be profitable if we do not consider training costs is like an airline telling us that it is profitable excluding the cost of fuel. Anthropic, by the way, expects to be fully profitable in 2028. Revenues growing fast, costs even faster. In addition to those training processes, both OpenAI and Anthropic are spending billions of dollars every year in inferencea section that is beginning to be even more important at an operational and strategic level. Currently, these inference costs represent half of each company’s revenue, although inference technology is expected to becomes cheaper and therefore the costs too. Here, however, there are two big differences between both companies: OpenAI: most ChatGPT users do not pay to use the service, so OpenAI assumes these inference costs without making them profitable. According to OpenAI, this facilitates adoption and will allow users to become subscribers in the future, something that is not happening too much at the moment. Anthropic: This startup has managed to win over many companies that pay to use their models, and it is evident that the company is absolutely focused on making you pay to use their models if you want to use them. And if not, Tell OpenClaw. Betting on the future. The companies and venture capital funds that have invested billions in OpenAI or Anthropic have made a bet on the future. They have blind faith that these companies will end up taking over the world, so the fact that today they are still not profitable does not scare them… or not enough to withdraw from this expensive race. Both have experienced spectacular growth that serves as an argument for investors. In addition, the growing interest of companies in integrating AI solutions by paying for them has boosted Anthropic and even caused OpenAI to reorganize and change its strategy. Less fireworks and hypemore focus in what makes money. The IPO as a trick to survive. Both companies are going to continue burning money like there was no tomorrow in the coming years, but now they hope that investors will be the ones to sustain their businesses. The amount of money they will need has made even the Nasdaq make things easier: It will allow newly listed companies to join its renowned index more quickly, giving them access to larger capital reserves. Now it will be the public market and to a large extent the individual investor who will decide whether they want to bet on that future or not. A small survey. Would you invest in OpenAI or Anthropic if it went public? It is evident that both companies generate different impressions, and although their strategies and ways of doing things are different, it is clear that this public sale offer is going to be very striking when it occurs. So, it is a good time to find out a little about what you, the xatakeros, think about this financial movement of these companies.

The world trembles over Hormuz oil while ignoring what feeds 50% of the planet

by

Geopolitics has a curious tendency to make us focus our attention on a specific point and not look at everything around us. With the scale of the tension in the Strait of Hormuzall eyes were on crude oil and the price of gasoline; However, experts warn that fertilizers are also in the spotlight. And the reality is that its collapse can cause a lack of food in our crops, since the vast majority depend on it. An invisible engine. Although the world seems to have forgotten about the fertilizers that arrive through the Strait of Hormuz, the reality is that we can affirm that humanity cannot exist without organic chemistry. And it is no wonder, because more than half of the food produced worldwide is available thanks to mineral fertilizers, as the IFDC points out. If we go further, the studies point out that nitrogen fertilizers Synthetics sustain the diet of almost half of the world’s population. And the worst of all is that, without this mineral contribution, global harvests will be directly reduced by half, so we are not talking about a product that improves performance marginally, but rather we are talking about the pillar of a food system that supports 8 billion people. A bottleneck. In this context of absolute dependence, the media focus is paradoxical. International attention and logistical surveillance focus almost exclusively on fossil fuels, ignoring the fact that fertilizers are a highly concentrated industry and closely linked to natural gas. But organizations like UNCTAD and media like EFE they have put figures to disaster by estimating that a third of global maritime fertilizer trade passes through the Strait of Hormuz. This means that logistical interruptions in the Persian Gulf directly affect millions of tons of agricultural inputs, which for the UN It is undoubtedly a major impact on global food security. There are no reservations. In recent weeks we have seen how different governments have announced with great fanfare the release of thousands of barrels of oil in national reserves. A strategy that has been built in recent years to be able to cushion this type of geopolitical shocks, but with fertilizers there is no such thing. It has consequences. The analyzes of the experts point out in this case that the interruption of the fertilizer chain has a full impact on the field, since any interruption has a full impact on the bank. Here both the FAO and the World Bank They have been warning for months that the suspension of shipments from the Gulf can skyrocket food prices almost instantly, severely affecting countries that depend on food imports. But the problem is that right now there is a significant lack of infrastructure, since we are seeing that the sector is dominated by a few players such as Russia, China, India and the United States. This, added to the shortage of long-term storage networks, makes us think that the price of food may suffer a large increase in the coming weeks, as well as have a bad harvest of 2026. Measures to alleviate it. The Government of Spain recently approved a new text that, in addition to lower energy-related taxesalso opted to inject money into the primary sector. In this case, direct aid was offered to partially compensate for this increase in fertilizers with the aim of ensuring that the increase was not transferred entirely to the shopping basket.

China is giving an overwhelming lesson in nuclear power plant construction to the rest of the planet

by

The time it requires the construction of a nuclear power plant From the moment the concrete is poured until the moment it is connected to the electrical grid, it takes between 15 and 19 years in the West; between 7 and 9 years in Asia and the Middle East; and 6 to 10 years in India and Russia. And the total cost of the project usually ranges between 24,000 and 60,000 million dollars. Barakah 4 nuclear power plantin the United Arab Emirates, has four nuclear reactors, took 9 years to build and cost $24.4 billion. On the other hand, the nuclear plant Hinkley Point Cin the United Kingdom, clearly illustrates the execution problems faced by some Western nuclear projects. After several delays Its first reactor will come into operation at best 13 years after the start of construction of the plant. And its final cost will exceed 50 billion dollars. At an intermediate point, Vogtle Unit 4 is established, in the US, which has taken 11 years to be operational and has cost about 35 billion dollars. As can be expected, the number of reactors and the technology they use have a profound impact on the cost of the plant and the time that needs to be invested in its development. Even so, as we have just seen, construction costs and time vary greatly from one region of the planet to another, especially if we introduce China into the equation. And in this scenario the country led by Xi Jinping is unbeatable with a average construction time of 6 years per nuclear plant and a cost of $2,500/kW compared to the 10-year average and almost 8,500 dollars/kW for the rest of the planet. China’s recipe is the most competitive Shangwei Liu explains clearly in the article you published on the website of the Roosevelt Institute what is the strategy that China has devised to reduce the cost and time invested in the construction of its next-generation nuclear power plants. Its plan is based on two pillars: the reconstruction of the supply chain and economies of scale. To a large extent, China’s success is due to the fact that it has managed to create a national supply chain that is immune to the ups and downs and instability of the international market. In addition, it has a lot of qualified labor in all links of its supply chain. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. On the other hand, the economy of scale that has given China so much joy in a very wide range of markets also has a place in the production of the components required by nuclear plants. Furthermore, when replacing components manufactured abroad by local elements This Asian country managed to drastically reduce costs during the first decade of this century, and stabilize them during the last decade. However, there is another factor that works in China’s favor and that we cannot ignore: its coordinated industrial policy and stable regulatory framework allow it to carry out long-term planning. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. Its latest nuclear plant projects show a cost of between 3,500 and 4,500 dollars/kWwhich places it close to China, with 2,500 dollars/kW, and well below the average of 8,500 dollars/kW for the rest of the planet. This achievement is the result of approaching nuclear energy as an industrial assembly line and not as a set of isolated engineering projects. Again, economy of scale makes the difference. The US numbers are much less favorable. And the total cost of its latest nuclear plants exceeds $15,000/kWalthough presumably this figure will moderate until it barely exceeds the $10,000/kW in future projects. If Western countries want to drastically reduce their costs and moderate the time it takes to construct their nuclear power plants, they will necessarily have to look towards China and South Korea. The reconstruction of their supply chain is essential, and, in addition, they will have to resolve the crossroads posed by the commitment to large reactors, or by compact modular reactors. At the moment there are no other options on the table.

The largest data centers on the planet are guarded by dogs. By robot dogs

by

The deployment of data centers to train the artificial intelligence It is a sign of technological power, but also economic power. This year alone, the big Americans are going to let themselves more money than NASA invested to take man to the Moon. More than $670 billion between Meta, Amazon, Microsoft and Google to create gigantic data centers. And within that investment, an important part is in safety with dogs. With robot dogs, specifically. It is the culmination of science fiction dystopia. In short. In the age of AI, data centers are the holy grail. We are continually seeing how companies sign contracts for thousands of million dollars with NVIDIA either amd (especially with NVIDIA) to provide them with the platforms with which to train their models. It’s only part of the equation, as there is another monumental investment in power, storage, RAM, dissipation and everything necessary to make these small cities work. Within the investment, there is security, and in BI They have published a report in which they detail that, within the budget, there are companies that are already including spending on robots that patrol both the perimeter and the internal corridors. The goal is security in every sense: patrol to detect threats, but also to identify any problems that occur with the equipment before they escalate and become something more serious. brand dogs. In the report, two companies are pointed out: Boston Dynamics and its dog Spot (with which we were able to play a few years ago) and Ghost Robotics with your Vision 60. Since Boston Dynamicsthe company owned by hyundai For a few years now, they have told the American media that they have been visiting data centers for some time because there is great interest. “We have seen an increase in interest in data centers in the last year, which is probably not surprising given the investment in that space,” Merry Frayne, the company’s senior director of product management, tells the outlet. For these companies, it is tremendous advertising, but also a potential customer in a “new” sector. Because it is possible that the police do not have the budget to get hold of many, but within the billions that are invested in data centers, dogs are just another sheet in the accounting excel. You can mount the sensor you want ‘Patrolling the center. And what is your task? Well… quite a task, really. The representative of Boston Dynamics, and other operators, point out that the dogs are not limited to acting as a “mobile surveillance camera”, but have other tasks: Patrol exterior perimeters to ensure that there are no problems with fences and accesses. Walk through server rooms, cooling rooms, and power rooms to look for anomalies such as water leaks, hot spots that may indicate a short circuit, or accumulations of moisture. Also sensors to detect gases, microphones to analyze noise and, ultimately, the sensor you want to put on it. Capture visual data from everything, such as analog pressure gauges or level indicators. Constantly, and as some robot vacuum cleaners do, map with LiDAR as they pass to see that there are no elements out of place. Some specific centers in which they are already being tested are Novva Data Centers in Utah or Oracle at the Industry Lab in Chicago. And dogs, in addition to cameras, have all kinds of thermal sensors and even conversational interfaces based on models like ChatGPT to interact with people. Measurement of noise levels Object identification Thermal sensors Compensate. It’s really nothing new. We have already seen robot dogs in other industrial sectors such as oil, mining or manufacturing. security forces. In China, in fact, there are deploying to assist firefighters in extreme situations or in institutesbut if in those scenarios they are seen as a tool, here they seem more like a substitute. Because there are those who have done the math and, in a market like the American one, a couple of full-time human guards can cost about $300,000 annually. The initial cost of a Spot ranges from $175,000 to $300,000, depending on the equipment. The cost of a Vision 60 is $165,000. And, as we see, they do much more than a security guard by being full of sensors. Frayne says, “Clients typically start to see a payback on their investment in about 18 months.” Michael Subhan, business director at Ghost Robotics, comments that “instead of having two human guards for $300,000, you can have one human guard and one robot.” A Spots battery charging. And it’s better, since it lasts less than two hours with the standard battery They also get tired. These robots also have their needs. They need to change batteries and install charging points and the environment must be well structured so that the routes are efficient and the sensors such as the LiDAR work well. They can climb stairs and avoid obstacles, but performance suffers in other environments and, in addition, the placement of fixed cameras and sensors in the building must be planned. That is to say, it seems that it is not as easy as saying “I build the center however I want, buy four robodogs and it will work”, but rather that you have to plan the traditional elements and the dogs to achieve a good integration. who are you HUGE Market. Although we have discussed two specific cases in which these robo-guardian dogs are being tested, both Boston Dynamics and Ghost Robotics have not gone into more details. In the end, it is security, and this falls within confidentiality agreements. Boston Dynamics points out that it is an “emerging market.” And Subhan has mentioned that “in the United States alone there are 5,000 data centers and 800 to 1,000 are currently being built, so we see it as a great market for us.” According to some estimatesthe market for robot dogs and industrial drones is currently around 500,000 units, but is expected to double by 2030, generating a market of 21 billion … Read more

The rain has transformed the driest desert on the planet into a sea of ​​flowers. It’s a sight to behold and a problem for experts

by

The Atacama Desert bloomed again in spring. After the August rains, more than 200 species from the Chilean region were activated and provoked the first major flowering since 2017. The Internet was filled with impressive photos, but (beyond the hype) there is a central problem: increasingly clear signs of a destabilized climate system. What has happened? In August 2025, a storm left accumulated between 40 and 60 mm in the Chilean Atacama Region. Specifically in the south: in Huasco, Freirina, Vallenar and the Llanos de Challe National Park. As a consequence, flowering started in the third week of September and reached its peak between the end of September and mid-October. He show was amazing: a mantle of red and yellow añañucas, of sighs, of huilles, of guanaco legs and lion’s claws. And why are we talking about this now? It’s a good question. Historically desert blooms occurred between 5 and 7 years. Typically linked to El Niño phenomena. In the last 40 years, Chile has recorded about 15 superblooms. The striking thing about this case (as happened in 2022 and 2025) is that it is linked to La Niña conditions. And, indeed, one may be a coincidence, but three so close together mark a trend. And the problem is that more blooms are not always good news. And so? As explained Maria Fernanda Pérezan ecologist at the PUC of Chile, out-of-season blooms generate a gap between flowering and pollinators. What’s the point of having pollen if we don’t have bees to do their job? Indeed: absolutely nothing. What’s more, if climate change causes this type of blooms on a regular basis, this deregulation could cause very serious problems. After all, just think that a guanaco paw seed can spend fifteen years on the desert floor until its time comes; If it germinates and there is no one to pollinate it, there will not be another seed. Climate change is going to cause us more problems than we are able to imagine. Because the serious thing is not the sea level, the melting of the glaciers or the rise in temperatures (that too). The most important thing is these little things that change everything. Things so small that we haven’t thought about them.
