Alzheimer’s starts long before its symptoms. And we have discovered one of its first mechanisms

by

We generally associate Alzheimer’s disease with memory loss since this is probably its most visible symptom. However, it is still what we do not know about the biological processes that unleash these symptoms. Piece by piece, we are solving this immense puzzle. New mechanism. A team in which researchers from the Severo Ochoa Molecular Biology Center (CBM-CSIC-UAM) participate He has discovered A mechanism linked to the early development of Alzheimer’s disease. The key component of this mechanism is in a protein called SFRP1. Astrocytes and SFRP1. As described by the team responsible for the finding, in the origin of the mechanism are brain cells called astrocytes. Astrocytes They are glial cells (A type of nerve cell) that for a while we thought were “assistants” of neurons but whose relevance we are seeing grow. In a mice -based model, the new study has shown that these cells could play an important role in the appearance of Alzheimer’s through an “excessive” production of the SFRP1 protein. This protein is one of the compounds involved in the regulation of communication between different cells during development, but in later stages of life its excess may imply risks. A “jam” in the brain. As the equipment continues, the accumulation of the SFRP1 protein in the adult brain is associated with chronic inflammatory processes associated with aging, and also to Alzheimer’s own disease. The problem arises when this excess blocks the activity of the adam10 enzyme, which plays a key role in maintaining the proper functioning of neuronal connections. “This blockage generates an imbalance that deteriorates synaptic plasticity, an essential cell mechanism to form and consolidate memories that allows neurons to regulate their connectivity in response to different stimuli,” They explain in a press release. Long -term synaptic potentiation. The accumulation of the SFRP1 protein would thus be interfering with a process called LTP or long -term synaptic potentiation. This is a “fundamental” process for learning and memory, the team stands out. A vital process in brain plasticity, that is, that allows the neuronal connections that are most frequently used to be reinforced, something indispensable when consolidating new memories. The details of the study have been published In an article In the magazine Cell Reports. A possible trigger. The fight against Alzheimer’s is a fight against the clock. The appearance of its most easily noticeable effects is associated with lesions already irreversible in the brain, so the only remaining route of action is to delay the advance of the disease. The techniques focused on detecting the internal signs of the disease, mainly the accumulation of amyloid plaques in the brain can allow us to advance ourselves to the appearance of the external symptoms of the disease. Now, the new study Open a road To get into stages still prior to the disease. “The increase of SFRP1 in early stages seems to act as an active engine of pathology, not as a simple companion of other degenerative processes,” Explain in the press release Guadalupe Pereyra, co -author of the study. Beyond rodents. Like any study in mice, extrapolating its conclusions can be complicated, so studies that validate what you have learned and the degree to which it is applicable to the development of the disease in humans will be needed. Converting what has learned into new therapeutic pathways will not be simple either, but this type of advance can help us in different ways. First, because understanding the disease and its mechanisms is essential in order to find a future cure; and second, since in the fight against their symptoms, Early detection It is a very important advantage.

IBM fired 8,000 workers to replace them with AI. What I did not expect was to hire many others … for the AI

by

The chickens that enter through the chickens that come out. IBM was one of the main protagonists in the Waves of mass layoffs globally Two years ago, and now it is again for the consequence of making this decision: having even more workers. The layoffs. In January 2023 IBM joined the Gray days In the technological sector. Google announced the departure of 12,000 of its employeesX (old twitter) fired 83% of its workforce in Spainand Spotify said goodbye to 600 workers. On the IBM side, I know They completely paralyzed hiring and the dismissal of 7,800 workers was formalized. IBM CEO itself explained That his company would cover artificial intelligence, affirming at least 30% of its workforce was replaceable. The consequences. IBM talked about how they could do without workers by replacing them for AI, but not about the people necessary to operate that AI. One of the executive directors of the technology, Arvind Krishna, collects to WSJ that the number of employees has increased after the wave of layoffs. “Although we have done a huge amount of work within IBM to take advantage of AI and automation in certain business workflows, our total employment has actually risen, because we have managed to obtain more investment capacity to cover other areas,” Krishna told The Wall Street Journal. The company has fired workers to replace them with artificial intelligence, but has also increased hiring in programmers and sales personnel. They have not transcended concrete numbers about how many hiring there have been and if they have really covered or not the 7,800 layoffs. The automation to command. IBM has been fully trusting more than three years Askhran artificial intelligence solution that began to take shape in 2021 and that Today they use for processes related to human resources management (payrolls, employee documentation, vacation managed). The company claims to have automated 94% of RRHH’s routine tasks, achieving productive improvements worth 3.5 billion dollars in recent years in more than 70 business areas. This significant saving in human resources, according to the company, is allowing them to invest in other areas. An AI-FIRST company. On the IBM website we have detailed The official position of the company with AI. It is worthy of a Black Mirror chapter, but perfectly summarizes the state of AI in the workplace. “As the chatbot learned and became smarter, our NPS (Net Promoter Score) began to increase. We added more functionalities, along with the ability to perform transactions. Askhr evolved to a digital assistant that allowed managers to transfer employees to another manager or initiate the quarterly promotion process. Everything was done directly in Askhr With just a few clicks. In 2024, Askhr He managed more than 11.5 million interactions; 94% of them were resolved within the platform. That means that, of all the questions asked, only 6% needed to be derived from Askhr To a specialized partner in HR. The current NPS is +74, so we have traveled a long way from that -35. There are almost 90 automation integrated into Askhrand more on their way. Thanks to this, managers can make HR transactions 75% faster than before. According to IMB, automating processes with AI has allowed you to be faster and more efficient, with a minimum need to derive HR personnel processes. One of the keys is in the evolution of the assistant: they have been using it in tests since 2017, and in 2025 it is already replacing humans. IBM is not alone. The companies replacing workers for AI was not an experiment of 2023. There are already companies that have dispensed with 90% of their customer service departments by Chatbots, ensuring that it was the right decision. Duolingo started 2025 With replacement of human teamsome already shot them through the cylinder head and They ended looking for programmers on LinkedIn. AI and its labor impact It is especially linked to process automation. Reports like ‘The Future of Jobs Report 2025’prepared by World Economic Forum, hope that by 2030 the Process automation destroy about 92 million jobs.

The obsession with flat belly and radical thinness

by

As every summer, aesthetic pressure marks the pattern again, and this year social networks have found a new goal: the flat belly. Although it seemed that the ideal of the perfect body It was fadingthe viral content has demonstrated otherwise Social networks mark the pattern. A movement It has emerged under the name of “average complexion”. In many videos It can be observed To people, mostly women, showing their body under the pretext of being “neither skinny nor fat”, thus perpetuating unrealistic beauty standards. Influencers Like Carla Flila They have pointed out That this type of content “only generates unnecessary insecurities” by promoting a standard that, far from being inclusive, continues to be exclusive and harmful. Beyond Trend. This phenomenon is nothing more than the tip of the iceberg, since There are many other videos how to “deflate the belly” or “routines to have flat belly.” In them you can visualize express exercises, miraculous diets and advice without scientific basis. All for the insatiable search for an ideal of beauty: the flat belly. Deeper. But what seems like a simple aesthetic tendency has deeper repercussions. A study by the University of Malaga analyzed How within the apparently harmless content you can find publications that actively encourage eating disorders. This duality has highlighted how difficult it can be to distinguish between content that simply promotes exercise and one that, under the disguise of healthy recommendations, encourages dangerous food behaviors. In addition, other research published in Behavioral Psychology showed How brief exposure to representative images of the ideal of thinness has a negative effect on the self -esteem of the participants, increasing anxiety. A persistent stigma. And if the discourse in networks reinforces little inclusive standards, Gordophobia continues to feed body dissatisfaction from another front. A recent UNIR report entitled “Between the healthy and the cult of the body”He revealed that 43.8 % of the boys and 34.7 % of the girls have high levels of Gordophobia. In fact, such as They have detailed In CTXT, Gordophobia is not an isolated prejudice, but a tool that keeps people in a state of constant body dissatisfaction, promoting harmful behaviors for physical and mental health. An endless cycle. This aesthetic pressure is not a new phenomenon. For centuries, the bodies have been molded and controlled by the prevailing aesthetic ideals. The idea of ​​a flat belly in the most recent history began in the nineteenth century, when women They were pushed To use Corsés to get the iconic “Wasp waist”, a symbol of femininity that deformed its ribs and hindered breathing. Almost arriving at this century, in the 90s and early 2000s, the beauty ideal turned towards extreme thinness, popularized by models such as Kate Moss and the call “Heroin Chic“Today, social networks have taken over, perpetuating that cycle of unattainable standards that transform bodies into shaped objects. Outside the networks. Aesthetic standards seem to take another way again, have we returned 20 years ago? The issue is that after a parenthesis in the 2010 decade marked by the rise of movement “POSITIVE BODY“, which included a diversity of bodies, now fashion derives Towards extreme thinness. With the reappearance of the Victoria’s Secret parade, which has bet again by hyperdelled models after years of criticism for their lack of diversity, as well as The reintroduction Of aesthetics and 2k in haute couture brands, they make it clear where the aesthetics wants to return. While social networks continue to amplify these restrictive canons, it is worth asking what will be the impact on the mental and physical health of those who are dragged to pursue unattainable aesthetic standards.

The photovoltaic industry has entered its self -replicating phase

by

Maximize the performance of solar panels is one of the great challenges of Photovoltaic industry. But it is something that is not limited to make more efficient panelsbut to engineer ways that they stay clean for longer. Because the great enemy of the panels are not the clouds, but dust or snow. Cleaning these homemade panels is clue For three reasons. The first is that a clean panel is more efficient. According to estimatesa dirty panel produces up to 39% less a year. The useful life of them increases because corrosion and other damages are avoided and, as more electricity generates, production is optimized and the Investment return. There is robots designed to clean them And we have seen them in all shapes and sizes, even tractors manually operated with a roller that rubs the surface of the panels, but one of the challenges is how to optimize the cleaning of the panels in the huge ‘farm’ installed in deserts such as Chili, China either India. And the answer is another robot, but not anyone: a robot that in turn is a solar panel. Solar panels that clean solar panels that clean … Be more or less autonomous, robots need energy to work. It can be through long cables that feed them or by batteries in the longest facilities, so when they are not cleaning, they are wasting time. Especially in desert scenarios in which dust is a problem. And the sauce of this matter is the following video: What we see in Action is a robot of the Chinese company Sunpure, a company that has specialized precisely in the creation of devices to clean solar panels. Beyond the conventional ones, they have two models that have a solar panel in the upper part that is the one that provides energy so that the rollers work and can give the necessary passes by the rows of panels. One is that of the upper video, called Venus, another is the one that we leave below: The difference between this and Venus is that the new robot has more upper surface occupied by the solar food panel, seems more adaptable to different panel sizes and, above all, is easier to clean. The reason? When it reaches the end of the row, a brush awaits you that passes the panel of the robot itself, cleaning the dust that may have accumulated. This cleaner robot has already been installed in some photovoltaic plants, such as those of India or Uzbekistan, and the previous model is the one that works cleaning The CME1 panels, the largest photovoltaic plant in Chile In the Atacama desert. They are curious, but beyond that, this type of robots is a necessity. Equipo them with solar panels is a good idea that they can perform those cleaning tasks in locations in which dust is a problem. In fact, those of this company are working, above all, in plants installed in deserts. Now, the great step of the industry both in the face of mass production and the most homemade is the creation of self -impossible solar panels. It is something that is already working on, with advances as interesting as that of the Startup Sol Clarity, a company derived from the University of Boston. Baptized as electrodynamic scren, it is a very thin and transparent sheet that Load dust particles with static And, when he has caught them, the ‘sweep’ using electromagnetic waves. It is a good solution not to depend on robots and not be the black water hole which is the current cleaning of large -scale solar panels. And in a sector in which every kilowatt counts, that they are as clean as possible. Images and videos | Sunpure In Xataka | I thought the robots could no longer surprise me.

Will not catch anyone by surprise that The next step In the most premium gaming world it is OLED. This technology, reserved until recently for televisions, He has been penetrating the monitors for a few years And, little by little, it has become the spearhead of manufacturers. I have been using gaming monitors for many years: First a zowie with TN panel And then some IPS of AOC and Huawei. I hadn’t had the opportunity to try an OLED monitor, so far. I have been with the new MPG 272urx QD-OED MSI and experience has been, and is being superlative.

I think MSI has done a good job with the foot and base. The Peana has enormous stability and allows you to adjust the inclination in every way. It would have been the Repeanocha to be able to raise the monitor a little more than allowed, but the available height is acceptable. The foot is big, nothing out of the ordinary, but enough for us to need a wide desk. I have left it in the face of trying it during the analysis, but if my personal monitor would have arm hung Without a doubt. All by hand. Accustomed to my IPS monitor, using a screen with the cuts trimmed is a delight. They do not reach the end as in mobile phones, but they are well worked so that they are barely noticed. The control zone, located in the lower area, allows us to quickly access the OSD (the menus to control the monitor) and all the ports are easily accessible. The number of options and ports is wide, but what we will appreciate most is the Switch KVM To control two computers at the same time connecting the peripherals to the monitor. MSI MPG 272urx QD-OED | Image: Xataka And speaking of ports. MSI has not left anything behind. The monitor incorporates two ports HDMI 2.1a Displayport 2.1a (UHBR20) and a USB type C capable of delivering up to 98W of power. What does that mean? That the monitor admits 4K at 240 Hz via HDMI U 8K at 60 Hz through Displayport (without DSC) and is able to feed a laptop he alone. Do you remember the Switch KVM? Now he charges all the meaning of the world. An impeccable reality. The bulk of the population will not be able to take advantage of the Displayport 2.1a port. This requires last generation graphics cards that are faces and what Few users have. You can use your Displayport 1.4 cable (or HDMI 2.1 if you use consoles) without any problem and the experience will be very good. Moreover, you are quite likely to be forced to do so because one of the great inconveniences of UHBR20 is the one that cable is one meter. Just have the tower on the ground so that the cable does not arrive.

This monitor mounts A third generation QD-OED panel Manufactured by Samsung. It has a diagonal of 26.5 inches, 240 Hz of refreshment and 4K resolution (3,840 x 2,160 pixels), so we are talking about a density of 166 pixels per inch. It is an absolute barbarity and translates into several things, but what we are going to notice with the naked eye is the sharpness of the texts. The QD-OED panels They have a problem and that is that the separation between the pixels derived from their matrix can cause a kind of aberration to appear in high contrast areas. For example, on the edge of a black text on a white background we will see a finite pink line. That is solved with a greater resolution and that is what happens in this case. This effect disappears completely on this monitor. We will notice if we zoom and physically approach the screen, but it is not something that we are going to do on a day -to -day basis.

The Anti -Capa does a quite a good job in general, but nothing can with the brightness of a window located just in front of the monitor or a strong light source on the sides, as is my case. I have a window just behind and, even if it hides well, I can appreciate it. That said, the antiglare layer works well, but does not magic. As for the sprocket of the monitor, we are talking about 250 nits in SDR, 450 nits in True Black 400 and up to 1,000 nits (in a reduced percentage of the screen) activating the Peak 1000 mode. We can also alternate between templates for the SRGB, Delta P3 and Adobe RGB color spaces. I recommend True Black 400 for general use, but Peak 1000 gets brutal quality, especially if our room … Read more

The battery quality in mobiles

by

I have interviewed enough brand leaders to have something very clear: the battery is one of the characteristics that most influences the purchase of a smartphone. In Europe we seemed doomed to a very specific figure: about 5,000mAh that remained immutable generation after generation. Chinese mobiles have begun to mark a trend with 6,000mahbreaking it in specific cases such as the Redmagic 10 Pro with its 7,000mah or the recent one Honor Power, with 8,000mah. In addition to the clear war in relation to the milliamps-Hora this eagerness for Chinese manufacturers to bring the best batteries goes further: the focus is in their quality and usability. Crazy about capacity. Broken the 6,000th barrier, we published a piece that has not taken long to materialize: one regarding that this roof surpassed, We don’t know where the limit is. Honor has already managed to introduce 8,000mah On a phone with an 8mm thickness, the same of any other traditional smartphone. Realme rises to 10,000mahabsolute madness. From one year to another, the 5,000mAh of the competition have become an obsolete figure, although everything that shines is not gold. A change in industry. That this capacity has been unlocked has a main responsible: the Silicon-Carbon batteries. Here manufacturers have been pioneers by introducing this technology, which allows you to introduce much more energy capacity in the same size. From a time to this part, this type of batteries has become more and more popular, although some manufacturers (including the Chinese) They reserve them for China for a simple reason: costs. Beyond silicon. Longevity is another obsessions for this 2025, and OnePlus is the best example. His OnePlus 13t It is able to function without using battery, but electric current, when plugged in the current. This function, which we already saw in the past in Redmagic mobiles (and Sony already flirted with it in some Xperia), is ideal to preserve the life of the battery on the scenario that suffers the most: when it is connected to the current making discharge cycles. A perfect ally. A good part of the responsibility in these advances has it Catlone of the giants in the battery industry (mainly in the industrial and electric car spheres). In recent years, Catl has collaborated with manufacturers such as Realme for the joint development of batteries, betting on silicon-carbon as material. A dart to the rest of the manufacturers. The 6,000 (or more) MAH are becoming a standard, and now the glove will have to pick it up the rest of manufacturers outside China. Betting on this type of batteries is not cheap, but launching a terminal with a 5,000mAh battery will begin to become a competitive disadvantage for the rest.

Spain has fought the fight against gender violence. And it is translating into mortal failures

by

A woman named Lina went to the police last January. His ex -part Viogén. This system, based on an algorithm, determined that Lina was a “medium” risk person. Three weeks later it was allegedly murdered For your partner. It is not the first time that something like this happens, and shows that we have a serious problem with our potential dependence on algorithms. The origin of Viogén. The Interior Ministry development In 2007 the Viogén system (integral monitoring in cases of gender violence). Among its objectives was to make a risk prediction and, depending on that prediction, monitoring and protection of the victims. How it works. The system is based on the collection and analysis from various sources such as police complaints, protection orders or criminal record. In the complaint, for example, a series of questions about the episode of the aggression, the situation of the victim, the children, the aggressor’s profile or the aggravating vulnerability, such as economic dependence are asked. Risk levels. From that evaluation one of the four levels of risk is assigned to each case (1 – low, 2 – medium, 3 – high, 4 – extreme). Each of them entails specific measures that may include from the allocation of telecare devices to remote orders. At the extreme risk, women have 24 -hour police surveillance. Viogén 2. The system has evolved since its creation and in recent months its second version has been implemented, Viogén 2. As explained in article 14the algorithm was updated with novelties such as eliminating the unreissented risk and hindering the inactivation of open cases. Thus, a new supervised inactivation modality appears that sets police control mechanisms for a period of six months extendable to one year. That makes it possible to monitor cases in which police experts have not appreciated the existence of risk for women or this is low. Zero protocol. There are also modifications that will allow the victim to request it in a “voluntary, manifest and repeated” way to inactivate cases of unattended risk, low or medium. Even so, the so -called “zero protocol” designed to minimize the risk of victims who express their desire not to denounce. According to the Macro -New Equalitythe vast majority of victims do not report, and therefore also protect them: institutions only have knowledge of 21.7% of cases according to said survey. Tragedies everywhere. The problem is that the system is not entirely effective. The alleged murder of Lina is the last example of the limited reliability of Viogén. In October 2024 a 56 -year -old woman She was killed Despite having asked for help even twice. Before, in 2024, another woman was killed by her partner and her It was also part of the Viogén system. The algorithm seems to minimize the risk. In the case of Lina, for example, the Viogén system allocated the “medium” risk for it, and that seems to happen on more occasions. In September 2024, 96,644 women were within the Viogén systembut only 12 of them were considered extreme risk, 0.01% of the total. Both the Minister of Equality, Ana Redondo, and the Minister of Interior, Fernando Grande-Marlaska, They minimize errors Recognizing that “the model is not infallible, but saves many lives.” New alarm against AI and algorithms. In recent times we are seeing how there are more and more cases in which excessive confidence is granted to algorithms on especially sensitive issues used in administrations and public institutions. The AI ​​does not stop making mistake. It happened with the Veripol system using AI to detect false complaints: His real reliability was very debatable. Something before, in March, we lived the Ábalos Case scandal in which an AI used to transcribe the statements of witnesses and defendants made mistakes and ended up turning some paragraphs into a gallimatisms. The AI ​​system for facial recognition itself that is being used for example In video surveillance cameras in Madrid He has done too Jump alarms in privacy. In the United Kingdom an AI was used to predict crimes to the minority report, and Its results were unfortunate. Attempts to apply AI in judicial processes and police They have also generated worrying conclusions. Lack of transparency. These systems are usually also criticized for their lack of transparency. Veripol is a good example, but we had others. In 2024 we talked about the Bosco system, used by electricity companies to decide who and who cannot accept the social bonus for aid to the light invoice. The Government He refused to share the source code claiming reasons for public security and national defense. It is not a problem only from Spain: there is an algorithm that suggests to the US judges what convictions imposebut its code is a secret, for example. In such delicate issues, the lack of transparency on the functioning of these algorithms is especially worrying. There were no agencies for this? In 2021 the creation of A Spanish Agency for Artificial Intelligence Supervision (Aesia). It was apparently centered to monitor compliance with the Digital Services Law (DSA) on platforms such as great social networks, and in fact in 2022 Sevilla was chosen To house the first European Center for Algorithmic Transparency (Ecat). What about Aesia. More recently we have seen how AESIA finally wants to take shape with Its coruña headquarters and start operating in 2025 to theoretically focus on the application of the EU AI Law. Its objective is theoretically to carry out “measures for the minimization of significant risks on the safety and health of people, as well as their fundamental rights, which can be derived from the use of AI systems.” Both the case of Viogén and Veripol’s or what happened in the ‘Abalos Case’ are precisely likely to enter that area, and it remains to be seen if the activity of this agency manages to help both the algorithms used as well as its application are optimal.

The electric car has an average age of just 3.5 years and does not stop falling. It is very good news

by

Changing car is usually a reason for joy in a house. Unless you are forced by the circumstances of an unexpected breakdown or before what has been expected, acquiring a new vehicle is usually exciting for the buyer. And it is because, on average, it occurs every long. Whenever it is not electric, of course. A study. The average age of electric vehicles is 3.5 years. That is what the latest available report states S&P global in which this dynamic is studied. The figure is inferior to that of past years and remains down. In 2022, the Middle Ages was 3.7 years and in 2023 of 3.6 years. The figure contrasts with that registered for diesel and gasoline cars. Following the reverse road, the Middle Ages of the American Mobile Park has been growing over the years until it is 12.6 years. Taking into account that the electric car barely represents 3.2 million vehicles of the 286 million units in operation in the country, its impact on the Middle Ages is negligible. And in Europe? In Europe there are no data segmented by technologies. Acea, employer of manufacturers in Europe, only refers to the average age of cars in the continent and by countries. Points out that in Spain, According to the latest studiesIt is 13.9 years. A figure higher than the European average. In the continent, the average is 12.5 years. A figure that is lower because in Germany and France, the two largest car markets in Europe, the decade is barely exceeded. They are also the markets where more electric cars are bought. Belgium, the Netherlands, Ireland or Sweden, countries that are located in the European average or in the upper part in the purchase of electric cars, also have lower figures in the Middle Ages of the mobile park compared to the rest of Europe. On the contrary, Spain, Italy and all the rest of Europe have the most aged mobile park. Although the almost 14 Spanish years are far from the more than 17 years of Greece, we share with those countries that the market share in the purchase of electric cars is very low, just a third of the European average. Why is the electric car important? The impact of the electric car on the Middle Ages of the mobile park is evident, especially the smaller the market. It is shown that where cars are growing are more modern. This is because the Middle Ages of the electric, as seen in the United States and is presupposed in Europe, is very low. It has all the meaning of the world. If electric car sales continue to grow, the Middle Ages has to go down. In the study of S&P global It is pointed out that in 2024 there were 50% more electric cars in American streets than in 2022. If sales are stopped, on the contrary, the age of the mobile park will increase in line. In the United States, where the sample is more than 286 million cars the impact is very low. In Europe, on the contrary, the impact is more evident because we can segment through countries. It is estimated that there is 256 million cars in circulation in Europe But Luxembourg, Germany, Sweden and Belgium are the countries where there is a higher percentage of cars with less than two years. Removing the peculiarities of Luxembourg, coincide (again) with electric sales. Two good news. That the electric car continues to expand its customer base are good news for the fleet of vehicles at European level. Confirms that every view more customers are trusting technology and that adequate incentives There are more drivers willing to jump into the electric car. It also means greater security. This is independent of the new car sold. With European obligationsa new car is always going to be safer than one with more than a decade behind it. Although they were systems that have already been seen ten years ago, now all cars (regardless of the price) have to have systems such as rear camera, emergency braking or lane output alert. And a regulate. Although with good prospects. And is that S&P globalin its report in this regard in 2023, it indicated that 6.6% of the electric cars that were in operation a decade before had been sent to recycle. The figure is higher than that of vehicles with combustion motor (5.5%). This means that the electric car becomes obsolete before, which has all the logic. We are talking about a technology that advances very quickly and, above all, has been widely improved in the autonomy offered by the vehicle. It’s easy to think about Many vehicle fleets They have gone to better life as better options have been offered. In addition, it must be taken into account that the same has been seen in the second -hand market. The depreciation of electric cars It is much faster and more accused than those of combustion. If the company interested in selling it cannot place the car, the most logical thing is to send it to destroy if you need space and replace its fleet. More and more cars. To all of the above we must add that the average age of the cars is expected to remain in the coming years since the electric car seems to have an ally between the fleets. Countries like Belgium or Germany They have discovered that the company car is an especially attractive means to boost sales of this type of car. While a individual aspires to have a car for many years in property, unless you opt for a rentiercompanies often use this formula since it allows them to renew the fleet every three or four years. If we take into account that the electric car has grown a lot among rentals And companies of all kinds, we have years ahead where its Middle Ages remains very low.

Gemini should not be called Gemini. It should be called Google

by

In the last 25 years we have “google” things. If we wanted to find answers on the Internet, we were looking for them in Google. But Chatgpt is beginning to clearly threaten the future of that search engine, and a trend is growing slowly but sustained: we are increasingly looking for in Chatgpt or in one of its direct rivals, and every time we do less on Google. Will we “chatgpteand” things instead of “google them”? The solution: the king has died, live the king. If Google wants to prevent Chatgpt from becoming the tool to search and answer questions, it has a potential output: Make Gemini be Google’s central engine, turn the traditional search engine into an AI search engine. Hello, Google Classic. Gemini should be Google’s search engine, while Google’s search engine should become something like “Google Classic”, a relevant option but should end up going to the background. Google would continue to be called Google, but below the engine would not be the traditional search engine, but Gemini and its conversational search. OpenAI wins in users. Although Gemini has achieved (or overcome) to chatgpt in benefits and quality, today the general public associates with Chatgpt, not with Google. In Openai today they win in the most important battle: user. The danger is that chatgpt sweeps popularity. The US antitrust trial to Google He has revealed that Gemini has 350 million monthly users (at least they use it once a month). According to data from Google herself, Openai has about 600 million active monthly users. The data is not entirely conclusive and can be misleading. Perception – and some independent analysis They confirm it– It is that ChatgPT is for the moment much more popular than Gemini as chatbot. And Google’s search engine has broken. The feeling for a long time is that the drift of Google search engine is clear. There are divided opinions, of course, but what seems evident is that The search engine has broken And it is no longer what it was. That shows that those who seek human responses usually add “reddit” at the end to avoid artificial and useless search results. The “ai overViews” or “views created with AI” are increasingly frequent in the traditional Google search engine. The transformation, it seems, is underway. But Google is reacting. Here the company led by L actar Pichai is moving little by little, and we are seeing how its “AI overViews” begin to be increasingly frequent: when looking for something on Google it can often appear an answer generated by the which is located above the list of traditional links of the results page. Careful transition. Here the company is being clearly cautious because the reputational damage if they are wrong in the response can be huge, as they have already suffered Not one but twice. And yet, the transition seems to be underway, as shown by that recent behavior of the search engine. Google can be calm (for the moment). However, all this does not seem to be a problem for Google. The search engine market quota remains spectacular with almost 90% of the market According to Statcounter Globalstats data. A report by the sparkoro co -founder, Rand Fishkin showed That in searches the Google market share is 373 times that of Chatgpt, which in the best case would hardly have a 1% market share. Chatgpt is used to search, yes, but only three out of 10 times according to a recent Semrush report. People do much more to search in chatgpt. A Semrush report Analyzing 80 million Prompts shows that 70% of the requests of Chatgpt users were not to look for answers, but for other cases such as creating images, summarizing texts, writing code or doing their mates. But the antiponopoly trial stalks. These days Google lives one of the greatest threats in its history, if not the greatest. In the US they want to chop itand one of the consequences that are discussed would be to prohibit agreements Like Google and Apple To promote the use of your default search engine. Apple has already indicated that it does not rule out finishing using an AI search engine. And the rivals squeeze. And it is not only chatgpt or its search engine mode. Perplexity is a striking reference When looking for with AI, and Bing has been raising that transformation for some time. Microsoft had much less to lose in this market and bet everything for the search engine with AI. They and others are taking advantage (or will end up doing it) reality: these “response engines” are a powerful claim for users. They give you everything too massive, they take away work, and they conquer you with their conversational modes. Talking is more attractive (and natural) than looking for.

The last time all humans were on earth

by

It sounds like the beginning of a science fiction work, but it is a silent milestone in the history of our species. On Tuesday, October 31, 2000 marked the last day in which every human being of the planet was on this side of the atmosphere. Since then, there has not been a single moment in which full humanity has been confined to our native planet. A historical launch. That October 31, 2000, A Soyuz ship took off from the Baikonur cosmodromein Kazakhstan, carrying on board the expedition 1 of the International Space Station: the American commander Bill Shepherd of the NASA and the Russian cosmonauts Sergei Krikalev and Yuri Gidzenko de Roscosmos. The crew reached an incipient ISS on November 2, 2000. It barely had a couple of modules (the Russian Zarya and the American Unity, assembled in 1998), But since then, the orbital laboratory has been occupied uninterruptedly. For 24 and a half years, there is always some human floating about 400 kilometers on our heads. A quarter of a century. The International Space Station is a collaborative project between five space agencies (the American Nasa, the Russian Roscosmos, the European ESA, the Japanese Jaxa and the Canadian CSA). It is not only an international cooperation symbol, but an unparalleled scientific laboratory, that orbits the land every 90 minutes at a speed of almost 28,000 km/h. In this quarter of a century, the orbital station has reached a habitable volume greater than that of a six -bedroom house, with A 109 meter wingspan and an average of seven people always on board. It can attach up to eight spacecraft simultaneously and has hosted almost 3,000 investigations of more than 108 countries, taking advantage of microgravity to study from particle physics to the effects of space trips on the human body. The ISS gives the witness. Aged and with age of agelike the air leaks that bring their operators head, the ISS members plan to leave it in 2030, before A ship developed by Spacex The towing to a safe place for its atmospheric reentry. NASA’s strategy is clear: ceasing to be the owner and main operator to become a key client, thus ensuring the continuous human presence in the low terrestrial orbit. This will allow to continue investigating in microgravity (which is crucial for future missions to the moon and Mars), maintain international collaboration and promote a commercial space economy. USA It has just reduced the budget for ISS hoping that there is a rapid transition to the new commercial stations. Companies such as Axiom Space (with their Axiom Sation project), Blue Origin (With your Reef orbital) or Voyager Space (With Starlab, in collaboration with Airbus) They are developing new private orbital platforms. What if they are not ready in time? If commercial stations do not arrive by 2030, humanity will continue to inhabit the orbit low thanks to China. Vetada de la ISS, China has expanded its presence in space With the Tiangong Space Stationcontinuously inhabited since 2022. China not only plans to double its size of three to six modules in the coming years, but is already opening its doors to international cooperation, as demonstrated by the recent agreement for Train and send Pakistani astronauts To the Chinese Space Station. With NASA focusing on a commercial model and the exploration of deep space, Beijing is strategically positioned as a central actor and a possible alternative in the low orbit, especially for nations that seek to collaborate outside the US frame. A changing environment. But there is another reason why the United States has focused on the moon and Mars. The low terrestrial orbit faces the increasingly critical challenge of space garbage. Millions of objects, from dead satellites and higher stages of rockets to small undetectable fragments generated by collisions or antisatellite missile tests. These waste travels at huge speeds and represents a risk of collision constantly and potentially catastrophic for astronauts. ISS itself has had to perform numerous evasive maneuvers in recent years. Manage this problem through better follow -up systems (especially for small objects), the active withdrawal of the most dangerous waste and, above all, prevention and mitigation in the generation of new space garbage (such as rapid exorbitation of rocket stages) will be essential to guarantee the safety of future long -term crew. For now, and for almost 25 years, we continue to live the space. On October 31, 2000, it was the last day of an era in which humanity was anchored exclusively to Earth. Since then we have been, uninterrupted, a species with extraterrestrial presence. Human permanence outside the earth seems assured, but its sustainability will require even more global effort and cooperation.
