The Government is looking for someone to manage thousands of affordable homes. An unexpected candidate has emerged: Rental Insurance

by

The State already has a ‘girlfriend’ for its affordable rental housing. Barely a month and a half after the SEPES put out to tender a contract to find companies interested in managing its public park of rental apartments, a large pool of 17,300 propertiesthe Ministry of Housing already knows of at least one interested firm. Of course, one that perhaps Isabel Rodríguez’s department did not have: Seguro Rent, the same company that the Ministry of Consumer Affairs wants to impose a fine of 3.6 million for violation of rights. Those responsible for the company they advance that they have all the requirements included in the tender and boast of their “experience and training.” Manager wanted. To understand the case we must go back to December 1, when the SEPES (shortly after converted into HOUSE47) launched a tender which probably whetted the appetite of more than one real estate agency. The contract in question amounted to a total of 55.4 million of euros (not including VAT) and was basically looking for companies interested in assuming for two years the “comprehensive management of the leasing of the public housing stock for affordable rentals.” In total, the tender covers 17,324 homes spread throughout the country, although to facilitate contracting it was divided into lots. Specifically, four were created for different regions, with between 1,600 and 5,700 houses. A name: Rental Insurance. The announcement was posted on the Public Sector Procurement Platform and companies had just over a month, until January 8, to present their offers. At the moment at least the name of one is known: Rental Insurancea firm dedicated to leasing management that boasts of having managed more than 75,000 contracts. Specifically, the company aspires to become with one of the four lots tendered by the State, the first, which covers 1,661 homes located in Galicia and Asturias. In exchange for its management, SEPES (now CASA47) offers about 6.5 million. The company of course defends its resume to win the contract. “Alquiler Seguro has the experience and training required to take charge of the comprehensive management of the rental fleet, as it has been doing for more than 19 years with the more than 28,000 contracts it currently manages throughout the country,” has claimed the signature itself on a note. Bragging about history. The company does not stop there. In addition to highlighting his experience managing house rentals (including public protection), he remembers the agreements and collaborations he has had with firms such as YourTECHÔ and First Hfocused on access to housing for vulnerable people. On its website the agency presume also from its office network, with more than 50 points spread throughout the country, and its portfolio of tens of thousands of properties. Why is it news? Because Rental Insurance not only stands out for its greater or lesser experience. Beyond the criticism that you have received from entities such as the Madrid Tenants Union, the OCU either FACUAthe company it was news recently for a proposed million-dollar fine. In December, the Ministry of Consumer Affairs imposed a fine of around 3.6 million euros on it for violating user rights and taking advantage of its position of strength in the market. At least in December, when the news brokethe resolution was not yet final and the company was advancing its intention to appeal. During the investigation he had already presented more than a dozen allegations. Questionable practices. In the file, advanced by Cadena SERdetailed practices that were at least controversial, such as forcing tenants to take out insurance, being responsible for charges for non-payments or claims or paying for a ‘Tenant Service Service’. Not only that. The file also details the obligation for the tenant to accept being included in a file of defaulters. Your practices already FACUA denounced them at the end of 2023. When SEPES launched its tender insisted in the profile of the company that is seeking to run the public affordable rental park: “Management will be carried out from social commitment and not only based on economic criteria. For this reason, one of the services that the successful bidder must provide consists of the prevention, detection and early attention of situations of risk of loss of housing.” Images | The Moncloa, Rental Insurance and FACUA In Xataka | The Great Rental Review is not going to be a joke for millions of Spaniards: more than 4,000 euros more per year

China needs its own TSMC to withstand the US pressure. His best candidate already grows at a rhythm of vertigo

by

The US wants to avoid at any price that China has avant -garde photolithography equipment. These complex machines are necessary to manufacture very high integration semiconductorssuch as those used by the data centers specialized in artificial intelligence (AI). And without them the technological development of the country led by Xi Jinping has slowed down. It is fair What the US government wants. China is dedicating a huge amount of resources to the development of its own avant -garde lithography teams. Two of its largest investments They arrived in 2014 and 2019before the technological war of which we are witnessing was unleashed. In 2014, the Chinese government injected about 19,000 million dollars into its chip industry, and in 2019 this figure increased to touching 27.5 billion dollars. However, these investments pale in front of China at the end of 2023. And it is that just two years ago the government approved An investment of 41,000 million dollars expressly dedicated to manufacturers of lithography equipment. In any case, these machines are only one of the ingredients of a recipe in which the leading role is interpreted by chips manufacturers. And the best option that China has is SMIC (Semiconductor manufacturing international corp). This company has cost more than two years to refine its most advanced integration technology as necessary to produce integrated 5 nm circuitsbut your effort is already paying fruit. And is that, According to SCMPtheir income during the first semester of 2025 has increased by 22% if we compare them with the same period last year. And its benefits have grown by 35.6%. This is SMIC’s great challenge: go beyond 7 nm Dr. Kim, an expert in chips manufacturing who has worked in Samsung and currently investigating TSMC in the US, He maintains that SMIC It is about to start the production of 5 Nm chips. It is perfectly credible because, as we have just seen, we know with certainty that this company has been Working in this technology. And, in addition, Dr. Kim is a reliable source. However, this expert has pointed out something crucial that we should not overlook: the performance per wafer that SMIC has currently achieved in its 5 Nm nodes is less than 30%. When semiconductor manufacturers produce a chip wafer, some of those nuclei do not work properly. It is normal. And when they launch a new lithographic node their performance per wafer usually has a wide margin, but little by little, as engineers refine their integration processes, This parameter improves. A mature lithography can deliver to integrated circuit manufacturers a very high performance, but an incipient technology usually moves in the orbit of 50% performance, so only half of the chips produced work correctly. The 5 Nm chips that SMIC will manufacture for Huawei are possible thanks to a technology known as SAQP The problem is that for an integration technology to be profitable from an economic point of view, its performance by wafer has to be At least 70%. And, as we have just seen, Dr. Kim argues that the SMIC 5 NM node is below 30%. It is objectively a very poor performance, but we know what this low figure explains: the technique used by this manufacturer to produce these semiconductors. It is known as Multiple patterningand SMIC has used it for more than a year and a half to make 7 NM chips for Huawei and other customers. This strategy consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. It works, but is responsible for wafer performance is clearly improvable. However, all probability Integrated 5 nm circuits that presumably SMIC will manufacture soon for Huawei are possible thanks to a technology known as SAQP (Self-alledhed Quadruple Patterning), which is nothing more than a Multiple patterning more aggressive and sophisticated than the one used to manufacture the soc Kirin 9000s of 7 nm and other chips. A report published by the Taiwanese media Economic Daily News ensures that SMIC will start the manufacture of 3 Nm semiconductors equipped with GAA transistors (Gate-alall-around) For Huawei in 2026. However, this is not all. This article also maintains that this last company has already completed laboratory tests that pursue the manufacture of integrated circuits using carbon nanotubes. Huawei’s plan presumably is to give this innovation to SMIC to adapt it to large -scale production.

In the search to eliminate the lithium of the batteries, we have found the best candidate: multivent ion batteries

by

Lithium ion batteries move the world and, in the era of electrification, every time They are more important. They have a series of limitations and Lithium is a finite resource With a high environmental impact, which is a problem if we want to electrify mobility. There the future solid state batteriesbut meanwhile, a group of NJIT researchers He has had an idea to give more life to the current technology: squeeze the maximum current batteries. As? With multivent ion batteries. Multivalent ions. A team of researchers from the New Jersey Institute -Njit- had an idea. If lithium is key to current batteries, but also scarce, We could use more abundant elements such as magnesium, calcium, aluminum or zinc as a replacement or to ‘dopar’ current batteries. The objective was to maintain, at least, the properties of current batteries and, if possible, improve storage benefits without depending on lithium. There the multive ion batteries come into play. If Ion-Litio have only one load, multiveous ion batteries that use the aforementioned elements allow two or even three positive charges. This property, in theory, allows you to store more energy by ion. Not everything is perfect. This property, as exposed in the studyit allows to store more energy by ion, but if they are not used it is because they present an important technical challenge. Multivalent ions are larger than lithium and have a greater load, which makes their movement difficult within current materials. To make it easy, imagine that the interior of the cells of a lithium -ion battery is a sponge with a certain number of recesses that catch particles. In a multivete ion battery, it has more holes and each one catches more particles, but the sponge is also greater. Accelerated by AI. That was the great limitation of the technological industry, but what NJIT researchers have done is to put the artificial intelligence To work. In this context, the use of AI is ideal because it allows simulating a large range of possibilities, of which the most convincing to test them. The end of the AI was to find new viable compounds to create multive ion batteries and, for this, they used a dual approach. On the one hand, a model called CDVAE (Variational Crystal Dissemination Self -coach) that was trained with known crystalline structures to generate new materials. On the other, a model of LLM LLM LANGUAGE Aphinated to select only the most thermodynamically stable structures. When they finished the work, they discovered five new porous metal oxides that are shown as ideal for transporting multivalent ions quickly and safely. “One of the greatest obstacles was not the lack of promising chemicals for batteries, but the practical impossibility of trying millions of material combinations,” said Dibakar Datta, leader of the research team. “We resort to generative artificial intelligence as a rapid and systematic way to explore that vast panorama and detect the few structures that multivalent batteries could really do practices.” Structures isolated by AI models. Section A is that of the CDVAE. The B is that of LLM Beyond the batteries. The team states that it validated the structures generated by AI using mechanical-chanting simulations and stability tests, confirming that these isolated materials could be synthesized with great potential for applications in the real world. Currently, and with those results, from the NJIT they are collaborating with other laboratories to synthesize and test those materials designed by AI. And something that Datta highlights is that, as a collateral effect on research, they have demonstrated once again that AI can be “a quick and scalable method to explore any advanced material, from electronics to clean energy solutions, without relying on extensive tests by test and error.” Once the best results are isolated, of course, it is time to try them in the real world, but much of the previous work It accelerates considerably. A mere patch? Now, although changing the ‘formula’ of lithium -ion batteries can be a good patch, the objective of the industry is still put in the implementation of solid state batteries. The catalyst in them is not a liquid, but a solid that allows us to solve many of the problems of current batteries, while offering a Greater energy density and faster load times. They are batteries that are already developed and that are being driven by Much of the automotive industrybut the problem is that it is a more expensive technology and is not settled. Bringing it to the real world, for example, Mercedes is already in itwhile other brands like BMW say that, for the moment, they are not in their plans due to precisely the price.

Samsung is committed to fighting with nails and teeth the most powerful mobile chip race. The perfect candidate finally has

by

The world of semiconductors has a look set on the next generation of integrated circuits manufactured in lithographic processes of 2 nm. Meanwhile, the most advanced processors for mobile phones continue to use the 3 Nm processes. Giants such as TSMC have demonstrated their good work with proposals such as Qualcomm Snapdragon 8 Elitehe Apple A18 Pro Apple, and even the Xiaomi Xring 01. Now it is Samsung’s turn. The company has presented its Exynos 2500and it is much more than a processor. It is the company’s great opportunity to dissipate doubts about the performance of its mobile chips, one of the keys for the company’s semiconductor division to remain alive. Between surrender and reinvent the design of its highest range mobile processors, Samsung has chosen the second option. Why is it important. The Samsung Exynos 2500 It has been playing since last yearwith a production that did not enter into mass for the low performance he showed in the leaked tests. Going forward with the proposal does not show only that Samsung trusts this proposal: it is a message to the world about the point where they are and can become semiconductors. The company has not revealed what device this processor will premiere but, taking into account that there are Rumors on the table about a new unpackedit is more than likely to know him soon. The exynos 2500. I will not get bored with excessive technical data from the processor. Your keys are summarized in a simple way. It has a ten -core design, just like Xiaomi’s own processor. It is the only high -end processor, next to the Xring, with this design. It is its greatest particularity. Promises to be 39% more powerful in the process of AI. Supports cameras of up to 320 megapixels. It is built in the 3 Nm GAA process. Its largest nucleus is up to 15% more powerful than its predecessor. The main doubts are how these numbers will be translated in real use. Its architecture is quite similar to that of Xiaomi Xring (with Cortex X925, A725 and A520) and a Samsung Xclipse 950 GPU that will have to compete with the best adreno. The message. Ten -core CPU, cameras of 320 MPenergy efficiency and improvements in AI. Samsung has not fallen excessively Marketinians nor has he made promises that he cannot fulfill. It is a more powerful processor than the previous one, centered on AI and with support for the best technologies of the moment. The rest is about to prove. The key to Samsung. Samsung has been facing problems with its semiconductor division for years. Lose clients like Google To provide the pixel with their processor, it is one of the most recent blows, and survive to arrive with decent performance to the 2 Nm career is crucial for the future of the company. The company has delayed two of its most important projects today: the construction of its second manufacturing plant of avant -garde chips in Taylor (USA) and in Pyeongtaek (South Korea). They are projects that are still underway And they will be key to the development of their semiconductors but … it will use without customers. Exynos 2500 is the most recent test of the point where Samsung is in mobile chips. If it fails, the company will have it more difficult than ever to continue attracting investment.

Xiaomi did it really good with the Redmi Pad original. The Redmi Pad Se It is, in fact, one of the best -selling tablets in Amazon and one of the most popular mid -range devices in its category. Now the firm returns to the load renewing the device not with one, but with two tablets: the Redmi Pad 2 and Redmi Pad 2 4g. The differences? Better to speak in singular, because the only difference between these two devices is that one is compatible with 4G networks and the other does not. That said, we will know them a little better and to see what Xiaomi offers us. This is how Xiaomi money earns – they attract you and catch you TECHNICAL SHEET OF THE REDMI PAD 2 AND REDMI PAD 2 4G Redmi Pad 2 Redmi Pad 2 4g Dimensions and weight N/D N/D SCREEN 11 -inch IPS 2,5K resolution (2,560 x 1,600 pixels) 90 Hz Brillo: 500 nits HBM: 600 nits 274 ppp Format 16:10 Eye-Care DC Dimming Tüv Rheinland Low Blue Light Tüv Rheinlandflicker Free T*v rheinland circadian friendly certified 11 -inch IPS 2,5K resolution (2,560 x 1,600 pixels) 90 Hz Brillo: 500 nits HBM: 600 nits 274 ppp Format 16:10 Eye-Care DC Dimming Tüv Rheinland Low Blue Light Tüv Rheinlandflicker Free T*v rheinland circadian friendly certified PROCESSOR Mediatk Helio G-100 Ultra Mediatk Helio G-100 Ultra RAM 4, 8 GB LPDDR4X 4, 8 GB LPDDR4X Internal storage 128, 256 GB UFS 2.2 128, 256 GB UFS 2.2 battery 9,000 mAh Fast charging 18W 9,000 mAh Fast charging 18W rear camera 8 MP F/2.0 8 MP F/2.0 Front camera 5 MP F/2.2 5 MP F/2.2 Operating system Android 15 with Hyperos 2 Android 15 with Hyperos 2 connectivity WIFI 5 Bluetooth 5.3 Dual sim dual 4g WIFI 5 Bluetooth 5.3 others 4x speakers Audio hi-ores Dolby Atmos 4x speakers Audio hi-ores Dolby Atmos price Since 199.99 euros N/D Xiaomi Redmi Pad 2 + case – 11 “2.5K (MediaTak G100 -Ultra, 4GB of RAM, 128GB of ROM, WiFi 5 + Bluetooth 5.3, 9000 mAh battery, charger not included), gray (ES version) * Some price may have changed from the last review So are the new Redmi Pad 2 Redmi Pad 2 | Image: Xiaomi A generous screen. Xiaomi has incorporated a somewhat larger panel than the previous generation (11 inches compared to 10.61 inches of the original REDmi PAD) and has significantly increased the resolution: from a FullHD+ panel we move to a 2.5K that leaves us with a higher pixel density. The soda rate is the same, 90 Hz, and The brightness It has increased by 100 nits. It is an interesting improvement, within that we are talking about a mid -range tablet. Mediatek under the hood. The processor chosen by Xiaomi for its new tablets is the MediaTak Helio G-100, a SOC of six TSMC nanometers with a maximum speed of 2.2 GHz. Again, mid-range processor. It is accompanied by up to eight Gigas RAM RAM LPDDR4X and up to 256 GB of UFS 2.2 storage. They are not the fastest technologies in the market, but they should not give problems when navigating, seeing movies or series, reading or throwing a game to light games. Redmi Pad 2 | Image: Xiaomi A good dose of mah. The battery capacity also grows, moving from the 8,000 mAh of the Redmi Pad to 9,000 mAh in the new models. Seeing the increase in screen resolution and size, surely the autonomy is similar. The fast charge does not change: 18W. The operating system, meanwhile, is Android 15 with Hyperos 2. The connectivity tip. The key difference between both tablets is, as we said, connectivity. The 4G Redmi Pad has a processor compatible with dual sim dual 4g, that is, that inserting one (or two) SIM cards we can have data where there is coverage. It should be noted that this will affect autonomy. Redmi Pad 2 | Image: Xiaomi Cameras. No surprise here. Redmi Pad 2 have fair and necessary cameras to make video calls and little else. Without large displays, the rear camera has a resolution of eight megapixels and the front of five. However, the reality is that the camera of a tablet like this has a practically punctual use. Versions and price of the Redmi Pad 2 and Redmi Pad 2 4g The Redmi Pad 2 can be achieved in gray and green by 199.99 euros in its most modest version (4/128 GB). The 8/256 GB model amounts to 249.99 euros. As for the 4G version, the firm, for the moment, has not mentioned anything about its availability in Spain.

A group of scientists has proposed to infect another world and see what happens as an experiment. His candidate: The Enced Moon

by

While NASA’s rovers are still looking for clues on Mars, Jupiter, and Esturno, Saturn’s icy moons, of Jupiter, of Jupiter, They have become the main candidates to house microbial life outside the earth in the solar system. But what will we do if we discover that they are not inhabited? A controversial idea. Encard, with Your subsurface ocean and confirmed presence of crucial elements for lifeIt is a usual focus of scientific fascination. The European Space Agency Plan to send a probe there which would arrive in 2054. Anticipating a disappointment, a group of astrobiologists has launched a bold proposal: if it turns out to be uninhabited, we can consider “infecting it” deliberately with terrestrial microbes to observe how life spreads in a habitable but virgin world. An unprecedented experiment. Since they began to explore the solar system, large space agencies have taken very seriously not to contaminate other planets and satellites, building their probes in clean rooms to reduce the number of bacteria that could survive on board. This experiment would be to do the opposite. It would be the first planetary scale attempt to build a biosphere. It would force us to learn how to assemble complex ecosystems from scratch, which organisms are the most appropriate to do so and how they behave in extraterrestrial conditions. Why sow life in another world. Charles S. Cockell, Holley Conte and M. Dale detail their idea in an article published By Space Policy magazine. The group argues that, if future missions confirmed the absence of native life in Encela, the deliberate inoculation of the satellite would help us understand how life spreads in permanently dark oceans. Inoculation would allow to investigate how bacteria ecosystems were organized On the ground snowball or even If hydrothermal chimneys From a primitive land they could be the place where life arose on our planet during the early or early archaic times. A multiphendary economy. Entering a more speculative field, an inhabited brain could, in theory, become a source of materials for the exploration of the exterior system if humanity would become a multiparaneary species. The authors even mention the engineering of organisms as an option to make the new biosphere, transforming the ocean of the Saturn moon into a “biofuel production plant”, once our metanogenic bacteria have prospered. It could even resort to synthetic biology to design optimized organisms. Faster than terraft Mars. The experiment would, of course, a multigenerational company, but unlike Mars the terraftwhich would take centuries, the inoculation of an extraterrestrial ocean could be achieved with current technology and would be “much simpler and less expensive.” But there are also ethical implications. How many missions are needed to be sure that it is really uninhabited? Is such an experiment more valuable than studying the geological and geochemical processes of a virgin world? And perhaps it is also possible to ask: will we be able to guard a second biosphere, in addition to that of the earth, for multiple generations? It is worth thinking in the long term, but we must previously intensify our sense of responsibility for the Earth’s biosphere.

In the same way that you would not be able to play a game of Soccer with moccasinspersonnel recruitment experts recommend Adapt the curriculum to the job offer to give Priority to skills that the company claims. This Curriculum adaptation It is a basic strategy when applying to any job offer today. In the early 70s, Bill Gates used that same strategy to Adapt your academic skills In registration applications for Yale, Princeton and Harvard universities: three universities, three different Bill Gates. An actor: three characters In his autobiography ‘Code Source: My beginnings’Bill Gates tells how he faced his admission application in some of the best US universities. Although in the case of the young Gates it was almost a joke with himself, his strategy, reminds to which any candidate who runs to a job offer should do. In autumn of 1973, Bill Gates participated in a play during his last year of high school. It was there when he discovered in the theater a new way of relating With other young people and show aspects of your personality that were in the background in other activities that were usually carried out, such as programming or making long excursions through the mountains. Just then, Gates had to send income requests for universities. That raised some doubts about what his Labor future. The options that were raised were to go to Harvard and follow in the footsteps of his father as a lawyer; orient towards a more political profile studying public administration at Yale; or go to Princeton to train as an engineer and develop software, something he had already done His first steps. Bill Gates tells in his book that “while filling the requests, I experienced with my personality. As I had learned in the theater class, each was a performance: An actor, three characters“The millionaire said. “For Princeton I said that I wanted to be an engineer who knew how to develop software. I boasted with examples of my programs and emphasized my mathematics notes. To Yale I said that I wanted to study public administration and, perhaps right, highlighting my experience (like Ujier during a couple of summers in Washington DC), my fondness for the boy scouts and my interest in dramatic art.” However, the request that had more weight for Gates was the one he presented to Harvard, “as I wrote in my essay, I expressed my inclination for business and law,” following his father’s professional steps. All gates, all certain Sincerity It is something that recruiters They value very positivelyso adapt the curriculum for a certain position It does not imply lying in skills, but to give priority to those who have A positive impact In the position to which it is postulated. “We expect sincerity. If a person comments that he is good to work as a team, but in the day to day he avoids participating in meetings, that is where we see that there is an incoherence with what he explained in the interview,” he explained Lidia Sanz CostaTechnique of Selection, Development and Training in companies IMAN. The “Three Bill Gates” presented by the millionaire in their respective income requests They were realbut little was going to serve a software engineer to have learned the values ​​of the scouts, or have knowledge of dramatic art. For that reason, the young Gates arranged to play a paper highlighting only the skills that They contributed value to their candidacy. In this sense, it is increasingly common to use the help ofChatgpt to adapt the curriculum to a specific job offer.

Black Swans. This blackout is a candidate to be

by

How can we prepare for the unpredictable? We are already planning a trip or starting a business, or even if we are quietly fringing some potatoes at home, being Prepared to eventualities You can save us more than one disgust. For a person on foot, and even for a company, dealing with a blackout can enter a category of “foreseeable unforeseen”: we do not know when they will occur but we know from past experiences that it is likely that at one time or another, our light will leave for a while. However, it is likely that people in charge of managing the peninsular power Bru what this week With the same attitude. From his point of view, what happened was something never seen beforea good candidate to catalog like what we call a “black swan.” First of all, what is that of the black swan and where it comes from. The concept was popularized back in 2007, in the book The Black Swan: the impact of the highly unlikely, written by Nassim Taleb, expert in statistics and finance. In the work as essayist of This controversial thinker The concept of uncertainty has a great weight, and the idea of ​​black swan is perhaps the zenit of uncertainty. We are not talking about The 2010 movie Directed by Darren Aronofsky and starring Natalie Portman, nor of the animal (although the theory owes its name to this animal). A black swan is an event with two characteristics. The first is that it is a possible but so unlikely event that it is unique in its category, an event that would be unthinkable although in retrospect it could seem even predictable. The second is that it is an event of great impact, we are not talking about a currency that falls singing while we play with it boring. The origin of the name is, we said, in the animal. And, as Taleb explains in his book, until the arrival of European explorers to Australia in the seventeenth century, for the West Swannes were white and talking about a black swan would be limited to the context of the fantastic. Everything changed with the arrival in Oceania and the appearance of dark swans. A Clear example of such an event It would be that of the attacks perpetrated on September 11, 2001. Although on that date the kidnappings of airplanes by terrorists were not something strange, the idea of ​​crashing these vehicles against buildings to maximize the damage caused would have been difficult to imagine. The event would not need to point it out, it also had global consequences. The Covid-19 Pandemia also had global consequences, a global epidemic caused by a until then unknown virus could be seen as a black swan (and in fact There are those who see it like this). However, the idea of ​​a global pandemic, even the idea that it could be caused by a respiratory virus, was not so remote and many raised it as a matter not of “yes”, but of “when.” The 1919 flu pandemic experience, or epidemics such as SARS (severe acute respiratory syndrome) not only look a posteriori As warnings, but they were already seen before the pandemic. Prepare for the unpredictable Taleb, an expert in statistics, explains that when we try to estimate the probabilities of an event, in general we have to rely on what we already know. For example, if we want Estimate probability that a new company Continue active A year after its creation, we can serve statistics based on companies founded in the previous years. If we want to predict if a team will win a game, we can also back and attend to the statistics of the team and the rival. That is precisely the limitation of statistical tools: it is among extremely difficult and impossible to estimate the probability of an event that has never been given. Well, what about the blackout? Undoubtedly, the April 28 blackout has been an event of important consequences that We will still have to evaluatethe damages caused by the cut not only the economic but probably had ramifications in other contexts. That part is out of place, the Great question Now is whether this was an unpredictable event. We may not be able to answer this question with certainty yet since, although little by little we are going Knowing new details On what happened, it is still early to know with certainty the causes of this great blackout. As for the dimension, we can find comparable precedents if we look outside of Spain, such as the Italian blackout of 2003 either The one suffered by Texas in 2021. However, those great blackouts were, in a certain sense, conventional. In the Italian case, the cut of a high voltage line that connected Switzerland with Italy fell, dragging with him the entire network of the transalpine country. In the case of Texas, the cold and its impact on gas electricity generation was the cause that the system could not with the demand for electricity of the southern state.

Finding quick and reliable tests for Alzheimer’s is a key mission for science. And we have a new candidate

by

Ahead of Alzheimer’s. It is a simple but difficult objective to achieve since the symptoms of this disease tend to appear when the disorder is advanced and has already caused important damage to our brain. A difficult objective but what It can help us treat the disease With greater efficacy, managing to delay the appearance of some of its symptoms such as cognitive deterioration. Maybe one day helps us cure it. In the blood. A group of researchers has tested a new blood test aimed at the early detection of Alzheimer’s disease. The test is based on a biomarker present in the blood, P-TAU217, which shows changes long before the appearance of symptoms in people with the disease. The study showed precision when detecting the disease greater than 90%. These results also did not depend on the age or gender of the participants, either on the existence of comorbidities or whether the test was carried out by specialists or primary care personnel. This marker can be measured with simple and cheap tools and the process is automatic, which can facilitate detection in various circumstances, democratizing the diagnosis of the disease. “This is an important step to bring simple blood tests for Alzheimer’s disease to health systems around the world,” said the team responsible for the essay in a press release. P-TAU217. Detection methods based on the P-TAU217 compound They are not exactly new. These types of tools are already implemented in the United States and it is expected that they will soon reach the rest of the world, says the team itself. The new method seeks to offer a simpler alternative to the available tools. The new study analyzed the precision of this New Test in the conditions in which it would be used, not only in specialized clinics but also in primary care. In three countries. The essay was carried out from 1,767 participants with cognitive symptoms distributed in three countries: Spain, Italy and Sweden. The details of the study were published In an article In the magazine Nature Medicine. The New Test included two cut points. One of them served to interpret the negative results: from this threshold the test rules out the presence of the disease. The second of the cut points serves to find the positive ones: this threshold shows the presence of the disease. This leaves, between one cut and another, a “gray zone” in which the results are inconcuing, however the use of a test with a single threshold slightly reduced the accuracy of the diagnostic tool. Above 90%. The study showed that the test achieved an accuracy between 92% and 94% when used in its two cuts mode. However, this precision fell to levels between 83% and 87% when only a cutting point was used and applied to more advanced ages. “When the method was tested in patient sides, the precision was between 92% and 94%,” NOëlle Warmenhoven explainedfirst signer of the study. “This is promising since this method will probably become one of the most used in clinical practice around the world.” In Xataka | We have a new “theory of all” to understand Alzheimer’s.

The candidate for the middle range repeats formula and adds a new ingredient

by

Samsung has a new secret weapon to conquer the mid -range of 2025. The Samsung Galaxy A56 5G is a dish made with the same usual recipe, but with a very typical ingredient of Samsung: The integration of artificial intelligence. This mid -range galaxy does not give up one of the fashion characteristics, as well as small improvements in hardware to remain a firm aspiring for the best middle range of the year. I have had some first impressions with this phone, and I tell you what I found in this first contact. Samsung Galaxy A56 5g, technical file Samsung Galaxy A56 5g Dimensions and weight 162.2 x 77.5 x 7.4 mm 198 grams screen Super AMOLED of 6.7 inches FullHD resolution Refresco rate: 120 Hz Vision Booster HBM: 1,200 nits CORNING GORILLA GLASS VICTUS+ processor Samsung Exynos 1580 GPU AMD XClipse 540 RAM 8 GB Internal storage 128/256 GB rear camera Angular: 50 MP, F/1.8, AF, OIS Great angle: 12 MP, F/2.2 Macro: 5 MP F/2.4 Front camera 12 MP F/2.2 battery 5,000 mAh Fast charge 45W Operating system Android 15 with One UI 7 connectivity WIFI 6E 5G SA/NSA GPS NFC USB type c others IP67 resistance Galaxy AI Circle to Search price 12/128 GB: 479 euros 8/256 GB: 529 euros A winning design and improved hardware The first thing that attracts attention in the new Samsung Galaxy A56 5G is its design. His predecessor, the Samsung Galaxy A55had the classic rear clean with independent cameras, without any module or strip. In this generation, the new model is committed to A differential design within the Galaxy familywith a strip that unifies the triple camera. In my opinion this is a success, it gives a completely differential touch in front of the rest of his brothers, making it clear that the family A has its own identity. This phone still has one of the best ergonomies on its sides, since on its right it has a cleft so that the thumb fits perfectly. It is also Something lighter and thinin addition to being finished in glass and aluminum, such as the most premium mobiles. About performance, he will touch on the review. The new exynos 1580 is an unknown and, although it comes to compete with the 7th series of MediaTek and Qualcomm, it will see how it behaves in Benchmarks. The first impressions with basic apps and menus are positivebut in the analysis we will deepen how this model behaves in more demanding scenarios. Its panel, 6.7 -inch Superamoled with a maximum brightness of 1,200 nits has seemed correct for its price although, one more year, I think that Working with frontal bezels is improvable. They are, perhaps, too high for a device with a starting price of almost 500 euros. One of the great novelties for this generation is the integration of artificial intelligence. It is something different and a more limited tad than the Galaxy AI of the Galaxy S25, but it has enough functions. Object eliminator Best Face: Edits by the photos in which the subjects come out with their eyes closed or “rare” expressions at the facial level Editing suggestions by AI Personalized filters Automatic video cutting by selecting the best moments for AI Selection by the contents on the screen to perform functions adapted to the content Reading articles and voice web pages This is one of the few mid -range phones in which there is a deep integration of AI, one that we will have to try in depth in the analysis. However, if this integration adds Android 15, One UI 7 a cycle of six -year updates (well above what manufacturers even offers in the high range), the combination is completely winning. A phone that will step loudly in the mid -range No, the Samsung Galaxy A56 5G is not the mid-range phone with better quality-precio, but that is not its goal. This is a phone for which he wants a phone below 500 euros, with reliable and lasting software, a design that is familiar and comfortable, and under the support of one of the largest weight companies in the industry. These first impressions leave us a good taste with their design, screen and potential at the software level. Now he has to conquer performance and chamber.
