SoftBank will pay 6,500 million per ampere. A new war chapter for data centers has just been written

by

At the beginning of last February the interest of the Japanese Softbank investment group was made public in The acquisition of the chips designer American ampere computing LLC. This last company is specialized in the development of Processors for serverswhich already put at that time on the table SoftBank’s intention to expand your business in large data centers. It made sense in a context in which the rise of the artificial intelligence (AI) is promoting that these facilities multiply at full speed. Just a month and a half later that strategic movement has established itself. According to your own AmpereSoftBank has just closed your purchase. He will pay 6,500 million dollars for this company and will have one more letter in the presumably prosperous business of the data centers. This investment group is The Arm owner since 2016; At the beginning of last October Invested 500 million dollars in Openai; And, in addition, it is one of the companies that lead The Stargate program with which the US seeks to sustain its dominance of AI. The war for data centers for AI is already underway The large technology companies that are involved in the deployment of AI are facing multimillion -dollar investments to develop their data centers infrastructure. Microsoft has confirmed that 80,000 million dollars will be spent during the fiscal year of 2025. and Google, 75,000 million. On the other hand, the Stargate program budget that I have mentioned a few lines above rises to no less than 500,000 million dollars. This is the cake from which SoftBank is being able to seize. At least a good portion. Ampereone chips will reach 256 nuclei for 2025 and presumably have a very competitive energy efficiency However, to achieve it the companies that control, or control in the short term, such as ampere, whose processors are implemented on ARM technology, will have to Compete with Nvidia, Intel, AMD, Google or Amazon. In any case, the ampereone chips, which are being manufactured by TSMC in their 3 nm node, will reach 256 cores For 2025 and will presumably have a very competitive energy efficiency. These are his great buzas against the proposals of the competition. The current situation is triggering something that is worth not overlooking. As Dan O’Brien has observedthe president of the American Futurum consultant, technology companies are forging strategic alliances with the purpose of molding the industry to their measure and maximizing the economic performance of their investments. As we have seen, SoftBank is the owner of ARM. On the other hand, Oracle has a very significant participation in Ampere, which will soon belong to SoftBank, and which is ARM client. In addition, all the companies in which we have just repaired, SoftBank, ARM, Oracle and OpenAi, participate in the deployment of the infrastructure required by the Stargate program. In any case, This network of dependencies does not end here. As we have seen, SoftBank is an important OpenAI investor, and this last company is Oracle’s partner and is trying to develop His own chips for ia. Finally, to curl the curl further, rumors that defend that Oracle is interested in buying Tiktok, a company that belongs to the Chinese company bytedance persists. SoftBank also has an important participation in the latter. As O’Brien argues In his tweet “everything is connected (…) It is fascinating to see how the technology titans shape the industry.” Image | Ampere computing LLC More information | Ampere computing LLC In Xataka | The B300 GPU is the new Nvidia beast for Ia.

How to look and review your fiscal data for the statement you will make in 2025

by

Let’s explain How to access and review your fiscal dataso that you have the option to verify what has a farm on your fiscal year 2024 in order to make the statement in this 2025. This is one of the most important previous steps of the 2024 rent calendar, and it is vital that you review it before accessing the draft. We are going to start the article by telling you what they are for and Why are tax data so importantso that you understand the reasons why you should review them. And then, we will tell you in a simple way how you can access them to consult them. What are your fiscal data for Fiscal data are The information that Hacienda has about you. In them you will see basic data such as your name and address address, but you can also find information about your open bank accounts, your furniture capital, your heritage earnings, the donations you do during the year, what work you have and what is your salary, or your quotes to Social Security. These are The data used by the Treasury to generate your draft For the income statement, so that if everything is fine you can present it directly. These drafts are not made by a person, but are automatically generated. And there is always the possibility that Hacienda collects some data erroneously in its databases. This also means that If your fiscal data is wrong your draft will be wrong. And this is not good, because in the event that you present a draft declaration with data that are wrong You will be punished with a fineeven when the draft has generated the hacienda itself, because the responsibility of reviewing them is yours. That’s why It is important that the data is updated and that they are all correct. And that is why this step is also vital before making the statement, because by making sure that your fiscal data is correct then you can submit the declaration much faster from the draft. Fiscal data will not be able to modify them with this procedurewhich is purely informative. The data They are only modified after generating the draft income. But doing this previous job You will already have the errors located To change them then when you have the draft. Thus, all the verifications you have to make can be done previously, and when the draft the process of changing everything will be much faster. How to see your fiscal data on the web To access your fiscal data, you must enter into The 2024 rental campaign website of the Tax Agency.

His first data revalidates Einstein and put the dark matter on the map

by

The Euclid telescope, launched in 2023 by the European Space Agency, has finished overwhelming its first great task. Designed to make a map in detail of the universe To help us understand dark matter and energy, Euclid has been analyzing three regions of heaven from point L2 of Lagrange. Despite being just the First mission data setwhich will extend at least until 2030, the European space telescope has already detected 26 million galaxies, some of which are 10.5 billion light years. Now the team, aided by volunteers and learning algorithms for reinforcement, has begun to publish the most complete and detailed map of the distribution of objects of the universe, which includes huge clusters of galaxies, bright quasars fed by supermassive black holes and gravitational lenses that divert the light of farthest objects. A first look at the Cosmic Network A deep field image of the Euclid space telescope Galaxies are not randomly distributed. They form a structure called Cosmic Network, similar to a web, whose filaments are made of ordinary matter and dark matter. Dark matter does not emit light, but affects the way galaxies are formed and evolved. Euclid accurately measures the shape, size and distance of galaxies to understand how the cosmic network is organized. He map that is makingwhose first three pieces have just completed, will be key to finding out what dark matter and dark energy are really. We know that dark matter exists because it gravitationally affects galaxies (it turns them faster than expected). And we know that there is a dark energy responsible for accelerating the universe. But they are a mystery. Different types of galaxies classified by human volunteers and the AI ​​of ESA Since its deployment, Euclid has sent 100 GB of data daily. It is impossible to manually classify each image, so scientists resorted to artificial intelligence and citizen science to classify 380,000 galaxies. 10,000 human volunteers collaborate in galaxyzoo.org To teach a so -called Zoobot to identify the different forms of galaxies. The volunteers classify the objects (“spirals”, “with arms”) and their responses are used to reset the AI ​​or readjust the accuracy of the algorithm. 5,000 strong gravitational lenses Gravitational lenses detected by Euclid One of the aspects that most excite scientists in the first Euclid data set are gravitational lenses. Euclid has already detected about 5,000 possible strong gravitational lenses, very rare objects that form obvious visual effects, such as arches or Einstein rings. These curvatures of space-time, predicted by the theory of general relativity, allow to observe distant objects that would otherwise be invisible, helping to understand how dark matter is distributed. It is expected that at the end of the mission, Euclid has identified about 100,000 strong lenses, multiplying the amount we currently know. Questions to solve The Euclid space telescope had a complicated deployment due to the accumulation of ice in its lens, but the ESA engineers managed to solve any setback. The results published today demonstrate the very high sensitivity of the telescope. During the next few years, Euclid will observe between 30 and 50 times these regions of the cosmos, accumulating more and more information and discovering new galaxies and phenomena. Added to the observations of the newly released NASA Spherex Telescopethe information we will have of the universe will increase exponentially. With the most detailed map of the universe, scientists will try to understand the nature of dark matter and dark energy, which make up 95% of the universe, and how they relate to each other, while solving other transcendental questions: what is the structure and history of the cosmic network? How has the expansion of the universe changed over time? Is the theory of the gravity of Einstein complete, or does it need large -scale modifications?

What is and how to avoid falling and that your data is stolen

by

Let’s explain WHAT IS THE TMO OF THE FALSE SMS OF A PACO WITH EL Corte Inglésa new scam that has begun to reach many users. The goal is to alarm by informing you of a false payment and lead you to a false website where you can get your access data. In this article we will explain how this scam works, and also where it seems to come. Besides, we will teach you Identify this type of deceptionwhich is very important to know that they are trying to scam and be able to avoid it. What is this type of scam A few days ago we found that the database of The English Court had been hacked. In this event Banking data were not compromised No user passwords, but other data such as telephone numbers seem to have leaked. Taking advantage of this confusion and the one we can not be very sure of whether our card has been filtered or not, a group of cybercriminals is sending some SMS in which They tell you that a purchase has been made with your account. In this same message you add a web address in which they say you can claim if the purchase has been a mistake. The SMS includes as title “Financiera Corte Inglés”, with which they try to confuse you to pass through this entity. In addition, they have altered the name of the sender so that some acronyms that may correspond appear. This is the first step to confuse users. In addition to this they use other tricks, such as including an amount of money large enough to alarm And try to make panic and hurry to lower our guard. They also add a web address whose URL contains the name of this entity, although the domain is a totally different one. The address points to a website that in some cases will already be blocked by your browser, but that can be A clonic page where your user data is requested or your bank data. The idea is that you write them and send them voluntarily. Although for those who already have knowledge of this type of scams, the deception is more evident, the cybercriminals have to send these messages massively, and that among the thousands of users to whom they are sent by there are some who pique and who can steal the account or their bank data. How to detect this scam The first clue that the SMS is false can be in The composition of the text itself. It is usually written in an incorrect or unprofessional way, even with some point where there should be a comma. This should be something that already caught your attention. But the most important thing is look at the web address included In the SMS. In the body of the direction you can put some name that refers to El Corte Inglés, but notice that at the end of the link there is a URL that does not correspond. By this I mean that if an address has a point in the middle, the main website to which it is what appears after the name. For example, if you have elcorteingles.paginafalsa.com, even if you put ELCORTEINGLESthis is a subdomain, as a secondary page, and the main one is what appears after the point, in the case of our example .paginafalsa.com. The real messages of the Financiera El Corte Inglés also begin by putting FinancialCorteinglesand this is something that cybercriminals have imitated. Normally the company will not include any web address In your real messages, and it is something that you must take into account. The best thing in these cases is that, given the doubt, you enter the web manually of financialelcorteingles.es either elcorteingles.es To look in your account if there is any payment. The website always writes manually, and Never enter from the link of an SMSbecause it is what cybercriminals want.

Netflix is ​​not worried that users cancel the subscription. The data reflect that, sooner or later, most return

by

How is it possible that content platforms on demand They rise in price year and year also if every time users cancel (or say they cancel) their subscription? It’s curious. Normally, in another context, it would be that price increases and foreseeable cancellations affected companies, but Netflix does not seem that it matters. Rather. Context. Despite price increases and the wave of cancellations that comments on social networks usually imply, the reality is that Netflix’s benefit It was 10,247 million dollars In the fourth quarter of 2024, 16% more than the same quarter of the previous year and the best result since 2021. Was the users canceling their mass subscriptions? If we understand “mass cancel” as in the United States only 19 million subscribers arrive in the fourth quarter of 2024 when Netflix expected 9.8 million, then yes. Comes back. According to data from the Analytical analysis company to which it has had access Business Insiderthe reality is as follows: price increases cause cancellations, yes, but users do not take long to return. The case of Netflix is ​​also curious because this “repentance” is greater than on the rest of the platforms. The data. According to Antenna, 50% of users who cancel their subscription subscribe at six months. If we expand the time range until the year, the percentage rises to 61% of users. In other words, six out of ten cancellations recover after the year. In the case of having canceled a price increase, the return will be with updated prices, ergo paying more and compensating in some way the cancellations not recovered. Moreover, it is most likely that user who returns to opt for a cheaper plan, but with advertising. 55% of the new highs They choose that modality, in fact. The data reflects that the Netflix subscriber recovery rate is much higher than that of its competitors Netflix vs the world. The consultant’s data shows that Netflix’s recovery rate is much higher than the average of the rest of the platforms. While at six months Netflix recovers 50% of users, the rest of the platforms barely recover 34%. In the case of Netflix it is also striking that two out of ten cancellations recover in just one month. There is a roof. Netflix has not stopped innovating in its programming, moving from series and films to also offer sports and live events. 300 million subscribers give good faith that this has worked, but everything has a limit. Netflix seems aware that 1) continuing to grow will be complicated and 2) “As we continue to invest in programming and offer more value to our partners, we will occasionally ask them to pay a little more to be able to reinvest and continue improving Netflix.” That is to say, that prices will continue to rise. Netflix knows that continuing subscribers will not be easy and maybe that explains that from now Don’t give that figure. We will know numbers of audiences, view, benefits, growth, etc., but not how many subscribers do Netflix have. Most likely, we will not see that data again until the 400 or 500 million are reached, very publicitable figures and from which the platform can breastfeed.

If you have the feeling that hotels are more expensive than ever in Spain, the data is right

by

If you have the impression that hotels are more expensive than ever, no, they are not your impressions. As the sector grows in Spain and the flow of foreign tourists reaches record levelsanother key indicator for accommodations also rebound: prices. Grow. At a good pace. Above Even inflation. And do so coinciding with A boom of the tourist floors that has already led to the administration to take action by Its impact In the residential offer. The data are of course revealing. A fact: 94 million. 2024 was a good year for Spanish tourism. Or at least this is reflected by the data handled by the Government, which in January He checked Due to the figures harvested by the sector: throughout 2024 the country received about 94 million foreign visitors, a record balance that exceeds the data of 2023 by 10% and arrived accompanied by a 16% rebound in spending, which in counting and sound money translates into around 126,000 million of euros. The Ministry of Industry and Tourism Trust In addition, the streak is maintained in 2025. Its estimates suggest that during the first four -month period will receive 26 million tourists, 9% more than last year, with an even more pronounced rise in spending. Things are somewhat different if we talk about the trips of residents in Spain, than in The third quarter Of 2024 they suffered a slight fall. January data 2025 2024 2023 2022 2021 2020 2O19 Daily average rate (ADR) € 112.8 104.9 95.7 85.7 62.2 82.1 81.4 Hotel Price Index (IPH) 141.9 133.7 124.2 112.1 95.2 106.5 105.4 Income by available room (Revpar) € 64.1 58.9 51.7 33.7 12.6 44.6 43.3 And prices? The flow of tourists imports, but it also matters the evolution of prices in hotels. And the INE data are in that case even clearer: the so -called daily average rate (ADR), which shows the daily average income obtained by occupied room, has grown at a good pace in the last years. The data varies depending on the month (as does the flow of tourists), but if we take as a reference August the progression is clearly appreciated: in 2024 it was 146.9 euros, in 2023 of 136.8 and before the pandemic, in 2019, it was at 109.3. In December it was 117, the largest ADR at the end of one year. Are there more clues? Yes. The income by available room and what the INE calls “Hotel price indices” (Iph). The latter is an interesting clue because it shows the evolution of prices that apply to customers housed in hotels, from the optics of the offer and including both normal rates and those charged on weekends in professional circuits, such as Turoperadores, large groups and companies. In December 2024, the iPph was 144.8 compared to 137 of the same month of 2023 and 109.7 of 2019, just before the pandemic. In general, it is the highest indicator for a year closure of the entire historical series, which starts in 2002. In its analysis, the INE takes into account all LPS Hotels, from the most basic to the five stars. Click on the image to go to Tweet. Going down even more in detail. A few days ago economist Ángel Talavera shared in X A series of data of Oxford Economics and Hover Analytics that help to better understand how hotels prices in Spain have evolved over the last five years. Specifically, it indicates the last rise in the rates, but above all its increase with respect to those charged before COVID-19. “Already almost 40% above prepandymia prices, which represents 20% more expensive by adjusting for inflation,” Precise The expert. Your data They reflect an increase in income from available room even greater, of almost 50%, and they arrive accompanied by some interesting reflections, such as the businesses that rise most are precisely those most expensive and cheapest, standing out with respect to intermediate accommodations. Comparing with the CPI. Another of the keys indicated by Talavera is the evolution of the cost of accommodation with respect to the evolution of IPC and the differences between them. The expert appreciates a clear “decoupling” Since mid -2022, with a significantly higher increase in hotel prices. The data The Ministry of Industry and Tourism also help to get an idea of ​​the evolution of the General Price Index and the specific tourism and hospitality. The trend is especially interesting in recent years, coinciding with the rise in rates in accommodations, largely driven by destinations such as Marbella or Ibiza, with historical prices. The data correspond to full years, except in the case of the current exercise. And what are the reasons? There are several keys. The economist points out an especially interesting: the double speed at which national and abroad tourism progresses. The data of Hotel occupation The INE shows that while the second grew 8.2%, that of the residents experienced a slight fall. TO The less at the country’s lodging receptions its number decreased 0.7%. Among the foreigners, the arrivals of the United Kingdom, Germany or France, countries with a per capita income higher than the Spanish. Over the last years the sector has also been marked by The boom of holiday rental, which has already forced the administration (both The central as at the level regional and local) to move file to control its impact on the residential market. The INE also shows how the Price index Tourist apartments has increased sensitively. Images | Martijn vonk (Unspash) and Segitur In Xataka | Spanish tourism faces the real risk of dying of success.

The difference between measles data in the United States and in Spain is in vaccines and is summarized in a figure: 95%

by

During these last months part of our attention has been placed in respiratory viruses such as The fluthe respiratory syncitial virus (RSV), and other viruses typical of these dates. This must be added Other epidemics such as gastroenteritis, also common on these dates and the avian flu epidemic that is causing serious problems in the United States and also threatens our wild and corral birds. While some of these viruses dissipate until next season, one returns with surprising strength: measles. The outbreak in the United States. Several measles outbreaks in the United States have already left 93 cases detected and 23 hospitalizations. At least 86 of these cases have been associated with three outbreaks, being the state of Texas the most affected, the state in which the first cases were detected. Some experts, such as Rekha Lakshmanan, of The Immunization Partnership, in Houston, see these figures such as the tip of the iceberg. “I think this will go worse before improving,” he explained in statements collected by Kff Health News. Texas is one of the more than 35 states in which the vaccination rate is below 95%: According to estimates Of the Centers for Disease Control and Prevention (CDC), the southern state has an estimated vaccination population of 94.3%. By ages. CDC data indicate that most cases have occurred between children and adolescents: 28 cases in children under five years (30% of cases), and 48 cases between children and young people among five and 19 years (52%). The measles virus. Measles is an infectious disease caused by a virus that especially affects the child population. It is a disease that spreads easily (at least among unbound people), through contact with nasal fluids, mouth or throat. The incubation period ranges between 10 and 14 days after exposure to the virus, after which the symptoms. The most characteristic of them is a cutaneous eruption that lasts between four days and a week. The list of symptoms can include other varied such as red eyes, cough, fever, muscle pain or nasal congestion among others. Measles is a potentially lethal disease in certain circumstances. Although complications are more frequent in adults, the main risk occurs in malnutrition contexts and is associated with vitamin A deficiencies, so it is developing countries that usually see mortality associated with this virus. Vaccine. Measles had disappeared from many countries thanks to the effectiveness of the disease vaccine. Measles immunization is done through the known Triple viral vaccine or SPR (for the three diseases that it tries to prevent: measles mumps or mumps, and rubella). The situation of measles in Spain. The situation is very different in Spain: so far from 2025, 110 cases of infection in Spain have been recorded according to the latest data from the National Epidemiology Center (CNE). As recently explained López Perea in an informative session organized by Science Media Center Spain, the cases registered in our country are due to small outbreaks with no more than a dozen cases due to outbreak. Many of these cases are concentrated in Euskadi. The Basque Autonomous Community has counted 41 cases of the disease. The total number of cases implies that we walk to a rebound with respect to 2024, the year in which 217 contagios were recorded, explained Sergio Ferrer, of SMC. Another substantial difference between the American outbreak and the shoots in our country is in the population affected by them. In the case of Spain, cases tend to affect adults and not minors. 95%. Spain has a good vaccination coverage against measles. The 95% figure is usually considered the limit of group immunity for this virus. In other words, a 95% coverage allows to stop the expansion of this virus. In the 2019-20 academic year, the vaccination rate In American nurseries it was 95.2%. Today has passed to 92.7%. In Texas, although the rate is higher than the US average, the figure is still below the 95%brand. According to the CDC data95 % of the cases detected occurred between unaccoured people or whose vaccination status was unknown. The remaining 5% occurred between people with a vaccine of the two that form the complete pattern.

The new data almost rule out the impact

by

The impact probability of asteroid 2024 YR4 has fallen from 2.8% to just 0.16%, according to the Coordination Center of objects close to Earth Earth. NASA, meanwhile, has gone from an estimate of 3.1% (The highest since these records exist) at 0.28%. Almost-off risk. Space agencies have more and more data from 2024 YR4 because they have been incorporating new observations throughout their exhaustive monitoring of the asteroid. Therefore, and although it has been fluctuating in recent weeks, the most reliable estimate of its trajectory is what the European and NASA space agency has just published. With A possibility between 625 that the asteroid falls on Earth on December 22, 2032 (one between 357, according to NASA), ESA believes that we can soon rule out all the risks associated with 2024 YR4. What has changed. The new observations from large telescopes such as the Great Canary Islands Telescope, 10 meters in diameter, have allowed astronomers Reduce the uncertainty window in its calculations on the asteroid orbit. The range of options has been closed that the object crosses the earth in 2032. With current information, the Earth is on the verge of probability distribution, on the edge of that uncertainty window. If the fan had continued closing with the earth in the center, the probability would have continued to rise, but now the planet, to explain it visually, is about to get out of the graph to stop being a concern. The Webb will help discard it at all. The Webb Space Telescope, with its extraordinary sensitivity to observe infrared, will be key to rule out the probability of impact. The asteroid is moving away from Earth at this time, But the Webb can continue seeing it until Mayunlike the normal telescopes they observe in the visible. The observation hours already reserved by NASA, ESA and the Canadian Space Agency with the Webb Telescope will be extended until May. Among other things, these sessions will determine the size of the object, which is estimated between 40 and 90 meters, in the absence of knowing the reflectivity of its surface. Chronology of an asteroid. 2024 YR4 was discovered on December 27 by the last system of land impact of asteroids (Atlas) from Chile, but did not caught the attention of astronomers until Automatically appeared on NASA’s Sentry list on December 31 for its impact risk greater than 1% with the planet Earth. The asteroid will go down in history as the first object for which activated the planetary defense action protocols established by the UN in 2018. Since then, space agencies have coordinated as many observatories as possible to follow it carefully. In May they will meet to deide what to do, unless the danger has been completely discarded.

Reviewing data almost 30 years ago, scientists believe they have identified a new ocean in one of Jupiter’s moons

by

On September 21, 2003 the Galileo probe He was immolated in Jupiter’s dense atmosphere, the planet he had been investigating for almost a decade. 30 years after the arrival of the probe to the Jovian orbit and more than 20 years after the end of its mission, the NASA probe continues to offer us new information thanks to the old data that it sent us in its day. A new oceanic world. The study in question has indicated that Calisto is “most likely” an ocean world, a rocky body covered by a layer of water at least in a liquid. The key to the new study has been in a more exhaustive use of the data provided by the Galileo mission, including all its magnetic measurements. Callisto Callisto It is the satellite farther from your planet of Among the so -called four Galilean moons of Jupiter. It is also the second largest moon of Jupiter, with a simular size to that of mercury but with a remarkably smaller mass. One of the most striking details is its surface full of craters which gives Callisto an appearance “similar to a golf ball” The suspicion that this satellite hid an ocean inside It is not newbut the intensity of his ionosphere had been a limit to our ability to study the interior of the Jovian moon from a distance. The reason is that researchers They believed That the satellite ionosphere, an electrically and located conductive region located in the highest layers of Calisto’s atmosphere, could be “imitating” the magnetic footprint that would emit a hypothetical salt and conductive water ocean. That is, astronomers could not know if the magnetism detected proceeded from outside or inside the moon. A new look. New data and analysis tools have allowed to solve this issue. The team responsible for the new study incorporated the set of measurements Magnetic available from the eight occasions in which the Galileo probe survived Callisto. Combining methods. The team combined the analysis of the data obtained by Galileo with a model that simulated Calisto’s ionosphere. They compared the results of the observations with what the suggested in the theoretical model. From the results obtained, the team responsible for the study concludes that the satellite ionosphere cannot by itself explain the magnetism detected, but that the existence of a salt water ocean under the surface of the moon could contribute to the observations. The results therefore suggest the existence of such an ocean. The details of the analysis and its results have been published In an article In the magazine AG ADVANCES. The oceanic worlds of our solar system. Calisto is just one more in The list of candidates To oceanic worlds in our solar system, a list that includes different bodies in which we believe, with greater or lesser degree of certainty, that there are oceans. This list includes other moons such as Europe, Ganymedes, Lord it, Triton, and also a dwarf planet: Pluto. These planets are of great interest to astrobiology since they are the main candidates to house life or the appropriate conditions for the emergence of this in our space neighborhood. That is why a whole new generation of probes is focused on The study of this type of environments. The list includes NASA’s Europe Clipper Mission, and Juice (JUPITER ICY MOONS EXPLORER) of the European Space Agency. The first will be focused on analyzing in depth the moon Europe while the European mission will travel to several of these frozen worlds to collect information about what their layers of ice hide. To these missions, China Tianwen-4 could be added, whose observations could also give us important data about Calisto and his hidden ocean.

An AI system will process a data flood

Madrid and other parts of Spain are being filled with cameras with artificial intelligence (AI). The City Council of the aforementioned city has been expanding its ambitious video surveillance system, focusing on points of great influx of public roads. But the expansion of these technologies does not stop there. In parallel, Renfe is developing an intelligent security system, where algorithms play a key role. Cameras in more than 400 vicinity stations. The rail transport company The installation has ended of an intelligent video surveillance system in 415 seasons of vicinity throughout Spain. The same has several pieces, among which IP cameras, CCTV recorders, video analytics servers and, as we said, algorithms of AI that give life to what they have called “spaces of high predictive security.” How does the new Renfe smart video surveillance system work? Traditional video surveillance systems depend on human supervision: it is the operators who must identify situations that require intervention. However, technology is reliefing this load when analyzing images in real time and sending automatic alerts to security centers when necessary. In the case of Renfe, the cameras are connected to the analytical servers of each station, in charge of detecting maximum afor and agglomerations. In addition, they allow identifying those who try to sneak into the accesses, falls in platforms or roads, fires and acts vandalism such as graffiti or damage to the furniture. The alerts arrive directly to the 24 -hour Safety Center of Renfe, promising to speed up the response to incidents. The rail operator recognizes that her security system had been obsolete. Although it had thousands of cameras spread over hundreds of stations, they lacked the technology necessary to integrate into the new monitoring system. To solve this limitation, the RS3 project (Renfe Smart Security Station) was launched, whose first phase has just concluded and whose second phase will begin in March. A millionaire investment. The project has a budget of more than 32 million euros and aims to modernize 597 stations distributed among the 12 Cercanías and Rodalies nuclei. The first phase, already completed, has been an investment of 25.8 million euros, while the second, which will cover the renewal of the systems in 182 additional stations, will have a budget of 6.5 million euros. Financing comes from the NextGeration funds of the European Union. What about the data collected? Every time there is talk of data collection, the doubt about the impact on user privacy arises. This makes sense if we take into account that European legislation is very strict in this regard. Renfe’s new video analytics system manages a large amount of data, but the company says it has taken measures to comply with the existing regulations. The system collects video images anonymously. Does not capture or record audio. Nor is biometric data. Processing is performed automatically with AI. The data collected are eliminated after “milliseconds.” In the case of the standard video surveillance system, the images are preserved last a maximum period of one month. The company’s privacy policy for your video analytics system states that users can exercise their rights, including the right to oblivion, opposition, suppression or limitation of data processing, sending an email to rights.viajeros@renfe.es. In addition, it offers A detailed map with the stations that already have the new security system.
