Neuroscience explains why the brain takes much longer to mature than we thought

The idea we have about adolescence right now it ends at 25 years old, this being the age at which supposedly the brain has just been ‘cooked’ forever to give way to a functional adult. But the reality is very different as the new studies point out, since we would continue to mature the brain until at least 32 years old. Where did the current idea come from? To understand why scientists pointed to 25 years as the age at which brain maturity ends, we must go back to studies of the past. Specifically to Resonance studies from the 90s and early 2000s like the classic Nitin Gogtay who mapped brain development and discovered that the cortex matures from “back to front.” This means that the sensory and motor areas are consolidated soon, but the prefrontal cortex which is in charge of executive functions, impulse control and planning is last in line. The problem is that many of those studies stopped following the subjects when you reach 20 or 21 years oldsince seeing that the curve continued to rise, it was assumed that the “peak” of maturity would arrive shortly after, around the mid-20s. But we had no idea what happened after this. Just assumptions. A new frontier. In order to solve this ‘blindness’ of neuroscience used the analysis of more than 4,000 brains using connectivity neuroimaging techniques at the University of Cambridge. What they saw was clearly five ‘epochs’ or milestones in brain wiring throughout life. Different turning points. And as if our life were a game, in the brain we have like five different screens that begin at a specific age that acts as a turning point. These ages are: 9, 32, 66 and 83 years. What interests us in this case is the period between 9 and 32 years, since the brain is characterized by a continuous increase in the efficiency and integration of neural networks. It is what the authors describe as an ‘extended adolescence’. It’s not that at 30 you think the same as a 15-year-old, but that the architecture of connections has not yet reached its final ‘adult’ form. Something that occurs at age 32 and remains stable until age 66, when brain activity begins to decline. To understand it better. Researchers wanted to use a simile to illustrate this new paradigm. To do this, they ask us to think of our brain as the union of several “functional neighborhoods” that specialize in specific tasks such as vision, language or logic. All of these are integrated with each other through different highways that are high-speed connections. Well then, between 20 and 32 years old The brain is balancing these two processes, so that the connections between different areas of the brain are well connected and organized. And it is precisely this typical pattern of the adult network, where the brain is capable of integrating complex information fluidly, which does not appear until after the age of thirty. Teenager at 30? This is where the important nuance comes in. Just because the brain continues to mature structurally does not mean that we should redefine adolescence in legal or clinical terms. All this because maturation is a gradient, not a switch of ‘now I’m a teenager and now I’m not’. To understand this, you have to know that the different elements of the brain and executive functions have a very different development curve. In this way, saying that the brain matures at 32 is a simplification that is as useful (or as erroneous) as saying that it matures at 25. What science really tells us is that there is no sudden development “blackout”; We remain biologically plastic and dynamic much longer than we thought. An opportunity for habits. This prolonged maturation is good news for all of us, since if the brain continues to actively ‘wire’ itself throughout our 20s, it means that structural plasticity is especially dynamic at this stage. In this way, science is quite clear: aerobic exercise, learning new languages ​​or facing cognitively demanding tasks during this “third decade” of life helps to improve the volume and organization of the brain’s white matter. On the contrary, factors such as chronic stress can affect the integrity of those connections. In short, a brain at 28 years old is not a finished product, but rather a work in progress that is finishing paving its best highways. The next time someone tells you that you should have your life figured out now because “you’re an adult,” you can tell them that, according to the University of Cambridge, your brain still has a couple of years of baking left.

2,000 years ago, Seneca said that “it is not that we have little time to live, but that we keep wasting it.” Science agrees

20 centuries ago, a man from Cordoba who had been quaestor, praetor, senator and consul of Rome and tutor to Emperors sat down to write a small treatise on the brevity of life. That was where he wrote that “it is not that we have little time to live, but that we waste a lot.” That phrase has spanned decades and decades, sticking in the minds of thousands of people and illuminating their lives. Or, simply, filling out internet pages that we have learned to consume as if it were any other entertainment product. A very popular one, by the way. In recent months, the Internet has been filled with Seneca quotes. The head of this report is one of them, but not the only one (“If you want to find true happiness, do not look for it in the great or the new, but in the serenity that simplicity brings.“, “there is no favorable wind for those who do not know where they are going“, “It is not that we have little time to live, but that we waste a lot“, etc, etc. ). And it’s curious… Does it make sense to go back to types from 2,000 years ago to solve our modern-day problems? And surprisingly it may be so. That’s what Philosophy professor Christopher Gill asked himself a few years ago.What if all that philosophical gossip goes further? “To what extent can we moderns recognize in these essays a plausible response to mental illness?” he asked. His answer, after studying Stoics and Aristotelians, is that Seneca’s texts; but, in general, these “philosophical essays were designed to function as a psychological analogue of the ancient medical regime.” What we would call today “lifestyle management” or “preventive medicine.” And, therefore, beyond the ‘pop philosophy’ of recent years, it is possible to find something of value in all those classic texts. Some of value, but not everything. In 1965, when she entered the Chinese Academy of Traditional Medicine, chemist Tu Youyou entered into a very long race to analyze each and every one of the remedies that the ancient Chinese civilization had been selecting. Most of them were pure pseudoscience, of course. A mixture of superstition, credulity and placebo. However, hidden among the trickery, there were real gems. The best example is the artemisinina revolutionary treatment against malaria. A treatment that earned him the Nobel Prize in 2015. It was sold like a Nobel Prize for traditional medicine, yes; but in reality, it was a Nobel for the slow work of screening, testing and discarding by the Ningbo scientist. That is what should be done with the practical philosophy of the Greeks and Romans. And, in this case, it seems that Seneca was right. First of all, because we have systematic biases that they push us to postpone and waste time. Secondly, because much of the “lost time” is not even conscious: it is pure “cognitive friction” (interruptions, multitasking, attention waste, etc.). And finally, because, according to available evidencewhen we reduce the lack of time, well-being increases. That is to say, it is not so much that we lack time as that we do not have a “well-lived” life. How do we fit all this together? Well, very good. Because “all this”, moreover, fits into the general idea not only of Seneca’s pamphlet in which it appears; but in the general outline of Stoic philosophy. And it is worth remembering that under all the naturalistic scaffolding of the philosophy of the old Stoics there was, above all, an ethical question: an imperative to live in accordance with nature (a, by the way, very rationalist vision of nature). In this sense, the Stoics they used to pay attention to what the human being could or could not do: since you have limited control over the length of your life, you must focus on how you live it; They told us while they invited us to order our behavior through moral criteria by dint of attention and peace of mind.

In Spain, couples no longer have children, they have pets. So they are spending millions of euros on gifts for them

Recently the Royal Canine Society of Spain made an experiment curious. He asked pet owners about their Christmas plans and found that the vast majority, 85% of the dog owners surveyed, planned to buy some “detail” for their furry companions, gifts on which they planned to spend an average of 35 euros. Not only that. Good part of the people with whom the institution spoke (56%) recognizes that on occasion he has spent more money on details for his dogs and cats than for family and friends. It may seem anecdotal, but these figures tell us a lot about an expanding business that is already moving billions of euros: that of pets. Pets and Christmas gifts. Studies are just that, studies, with their strengths and weaknesses, but they help us better understand some trends. Hence the survey posted last week by the Canine Society is so interesting: 85% of those interviewed plan to buy “some detail” for their pets this Christmas, spending on average about 35 euros per head. “More and more people understand Christmas as a time to share with family… also with them,” slide the organization, which estimates that above all, toys, special snacks, beds and blankets will be purchased. Is this something so strange? No. And for two reasonsmostly. The first is that in Spanish homes it is increasingly easier to find pets than children. The second is that we think less and less about spending hundreds or even thousands of euros on our four-legged companions. It comes with taking a look at the data from the sector or even from the INE to verify it. Right now the statistical institute has 1.8 million children under four years of age registered in Spain. If we talk about pets, however, the REIAC, the Spanish Network for the Identification of Companion Animals, had around 10.2 million dogs and 967,000 cats registered in 2023. There are many, but the data falls short when compared to those managed by other institutions, such as the Statista portalor ANFAC, the Spanish association of feed manufacturers. The latest report from the employers’ association concludes that in Spain there are around 20 million petsamong which dogs (6.96 million), fish (five million), cats (4.93 million) and birds (3.23 million) stand out. A growing business. These data are interesting because they do not only tell us about the love of Spaniards to surround themselves with pets. Together they form the basis of a business that is rapidly expanding: the care of pets. He latest report of Anfaac in fact shows a growing industry, which in 2024 had a turnover 2,053 million5% more than in 2023. Spending on cat food alone skyrocketed in one year about 12%which raised the total turnover of that business niche to more than 900 million. One figure: 175,000 million. “A household with a dog or cat spends, on average, between 160 and 220 euros per year on their food, to which we must add everything related to their care and health,” they clarify to elDiario from the NIQ consulting firm. Their estimates suggest that in Spain pet food already represents a business worth more than 2.2 billion euros, a figure that rises to around 175 billion euros if we value the market internationally. Is there more data? Yes. Another clue is given to us the last barometer of petparent published by Aedpac, the Spanish Association of industry and commerce in the pet sector. Their report shows that if all the money we invest in pets is taken into account, including food, veterinarians, insurance, hairdressers, hygiene items or toys, on average a dog owner spends 1,908 euros per year. In the case of cats it is around 1,728. “It is a growing market. We have not yet reached a bubble or saturation point because it is a solid reality, not a two-day whim,” explained recently to the newspaper Five Days Ignasi Solana, general secretary of Aedpac. The sector saw “an uptick” during the pandemic, but the growth of the pet care business appears to go beyond COVID. Redirecting the business. So much so that there are already toy stores and hair salons that have redirected their businesses to focus on pet care. Even some traditional manufacturer of traditional nougat has been launched this year for the first time to the lucrative (and above all growing) pet food sector. and the experience not seem to be doing badly altogether. “In our vision of petfood “We are talking about a business that represents more than 1,600 million and has been growing by close to 30% in recent years,” comments to elDiario Pauline Worbe, from the firm Worldpanel by Numerator, who remembers that in Spanish homes there are now more pets than children. “We are talking about a sector with promising prospects.” Beyond Spain. The phenomenon is not (far from it) exclusive to Spain. In fact, it is already being felt in such powerful markets. like chinesesupporting a billion-dollar market that expects to grow strongly over the coming years. In 2023 Bloomberg Intelligence estimated that the pet industry was already around 320 billion dollars globally and would reach around 500 billion by 2030. An understandable figure if you take into account that its analysts estimate that in a few years the pet food business will grow by 52%.

In Spain there are many graduates. The problem is that they are not the ones that companies need.

a study on educational quality in Europe has put in black and white one of the keys to what is happening in the labor market in Spain: Graduate rates in Spain have exceeded the European average. However, the data suggests that these graduates have studied the wrong races. The result is a mismatch in the labor market and a inefficient use of talent because an important part of those who have spent years training end up in positions that either do not require that level of education or have nothing to do with the studies they completed. ​Many university students, many vacancies. According to the report ‘Education and Training Monitor‘ Prepared by the European Commission, in the age group of 25 to 34 years, 52.6% of people in Spain have higher education. This places Spain above the EU average, with 44.1%, and the European goal of 45% set for 2030. This is great news since Spain has already exceeded the European goal for graduates, and even so it continues to expand that advantage year after year. The problem is that all these graduates do not respond to what the labor market is demanding. According to Eurostat data By 2024, 35% of higher education graduates aged 20 to 64 are working in jobs for which their level of qualification is not required, compared to an EU average of 21.9%. Spain is at the rate of highest overqualification in all of Europe. What is studied and what is needed. The European Commission emphasizes that this mismatch between the higher education courses being taken in Spain and the demand from companies is structural and that the Spanish economic system is not being able to absorb the volume of graduates it generates. ​The European report describes a low employability of graduates in humanities, social studies and arts, who are more likely to end up in jobs below their educational level or far from the field they studied. In parallel, it is noted that overqualification affects women to a greater extent than men, which aggravates the gender inequalities in qualified employment. On the other hand, the demand for specialists in STEM subjects (science, technology, engineering and mathematics), grows much faster than the supply of graduates. In 2024, the number of vacancies per worker in the green and digital sectors will exceed the average by 52% and 212% respectively, showing a growing gap between the skills coming out of the education system and those requested by companies. ​FP is taking off, but it’s not enough. The Vocational Training figures in Spain progress positivelybut they have not yet reached the point of balance between the supply of training and the demand for professionals. According to the study, only 10.1% of adults aged 25 to 64 have a mid-level VET qualification, well below the 34.6% average in the EU. This lower presence of intermediate qualifications translates into worse employment results. The data suggests that the average employment rate in 2024 of recent VET graduates is 68.6%, compared to the 80.0% European average and far from the target of 82%. Connecting education and business improves job placement. The dual vocational training reform It does seem to show signs of a positive impact on job placement. According to data From the Ministry of Education, Vocational Training and Sports, 73.8% of mid-level vocational training graduates in dual modality from the 2019-2020 academic year were working four years after finishing, compared to 66.5% of those who completed non-dual vocational training programs. Furthermore, 33.8% of dual vocational training students got a job in the first year after graduating, which confirms that direct contact with the company facilitates the transition to the labor market.

Renfe is obliged to return money after 15 minutes of delay. Its president warns that this “would make tickets more expensive”

The president of Renfe, Álvaro Fernández Heredia, assures that the company will not apply from January 1 the new compensation approved by Congress. He argues that the measure is “unconstitutional and generates inequality against Iryo and Ouigo.” Conflict. In November, Congress approved a PP amendment to the Sustainable Mobility Law that forces Renfe to recover its old compensation for delays. These are 50% refund of the ticket from 15 minutes of delay and 100% from 30 minutes. Currently, after the change which the operator made in July 2024, only returns money after 60 minutes (50% of the amount) and 90 minutes (100%). The amendment, which had the support of Vox, Junts, ERC, PNV, Podemos and BNG, sets January 1, 2026 as the date of entry into force. Renfe’s position. Fernández Heredia, has declared in RNE that “in principle, no” there will be changes next Thursday in the travel conditions. According to the president of the operator, the State Attorney’s Office is studying legal formulas to avoid applying the provision. “We have a legal opinion that clearly says that it is unconstitutional,” he said. explained in El País, arguing that it violates principles such as equal treatment, freedom of enterprise and two European regulations on rail transport services. The economic cost according to the operator. The president of the institution estimates the impact of the measure at more than 125 million euros annually, well above the 43 million that Renfe paid in compensation during 2023. As Fernández Heredia clarifies, the increase is not only due to more incidents, but also because the amendment extends compensation to all long-distance commercial services, including Avlo, Alvia and Intercity, not just the AVE. “Whoever wrote this didn’t know what he was doing,” pointed out to the middle. The consequences for the traveler. The president of Renfe warns that applying the new compensation would cause a 10% increase in fares and would displace up to 5% of passengers towards the competition. In addition, it warns that “deficient services that Renfe maintains in areas where Iryo and Ouigo do not operate would be put at serious risk.” “If we want it to be cheaper, provide deficient services and stop where no one stops, what we don’t want is liberalization,” declared in RNE. Inequality. The core of Renfe’s argument is regulatory asymmetry. And while this operator would have to return part of the money from 15 minutes late, Ouigo begins to compensate from 30 minutes (with purchase vouchers) and Iryo from 30 minutes as well. Both competitors only refund 100% of the amount after 90 minutes of delay, just like Renfe does now. “I don’t think this is being done because we want to improve the conditions of travelers, but rather because of an attack on Renfe,” he said. affirmed Fernández Heredia in El País. Legal battle underway. Sources from the Ministry of Transport they qualified the amendment to the media 20 Minutes as “demagogic and populist.” Minister Óscar Puente announced after the approval of the law that they would look for formulas to prevent its application, something that Fernández Heredia has confirmed is being studied. The president of Renfe regrets that the company “is not entitled to appeal to the Constitutional Court, which creates insecurity when it comes to defending ourselves.” He inherits the mark of ppolitical opulism. The president of Renfe was very critical of the parliamentary groups that supported the measure. “It was a slap in the face of Renfe to the Government,” as collected The Country. “It is a populist measure because they do not say that this measure implies ‘raising prices’ and that it will benefit the ‘other two companies,’” added in the interview on ‘Las Mañanas de RNE’. The president of the operator has asked the PP, Podemos and BNG for explanations about why the obligation only affects Renfe. “If we want to provide a guarantee policy and better compensation, the logical thing is that it should be for all travelers.” In Xataka | Public transport faces 2026 with extended aid and the approved Single Pass: there is still one step ahead

Researchers extracted photos and statuses from 3.5 billion WhatsApp users. Meta didn’t react until they told him.

Between December 2024 and April 2025, a team from the University of Vienna identified 3.5 billion active phone numbers on WhatsApp (practically its entire user base) from a single server and without encountering too much technical resistance. They processed more than a hundred million numbers per hour and extracted not only the existence of accounts, but also public keys, profile photos, status texts, and device metadata. They did it without having to hide, from the same university IP, same server, five accounts. For four months, no one in Meta noticed. Why is it important. This is not the first time that this vulnerability has been demonstrated, as it has already occurred in 2012 and 2021but the first at this scale and speed. The finding exposes a structural contradiction in WhatsApp: Your architecture should show whether a number is registered to enable contact discovery… …but that functional need collides with the privacy of its users. Knowing who uses WhatsApp in countries where it is prohibited, such as China, Burma or North Korea, can have serious consequences. There they detected 2.3 million, 1.6 million and five accounts respectively (not five million, just five). The investigation, published a few weeks ago in NDSS 2026shows that this crack not only persists, but has widened. The context. The researchers developed ‘libphonegen’, a tool that reduces the search space from billions of theoretical combinations of possible mobile phone numbers to “just” 63 billion real candidates for 245 countries. Using unofficial WhatsApp clients that directly access the XMPP API, they queried these numbers at a rate of 7,000 per second. Neither his IP was blocked nor his accounts sanctioned. Meta did not respond until researchers explicitly reported the finding in March of this year, and countermeasures did not arrive until October, just a couple of months ago. The figures. He dataset resulting five times higher the scandal of scraping from Facebook 2021: India leads the document with 749 million users (21% of the total), followed by Indonesia and Brazil. In Spain, 46.5 million accounts. 81% use Android. More than half have a public profile photo. 29% have the status text visible. Between the lines. The researchers were able to infer the operating system by analyzing initialization patterns of the cryptographic keys. Android starts certain identifiers at zero. iOS does this in random values. This detail matters because iPhone users are higher-value targets for attackers. They also detected that public keys are reused. They found 2.3 million different keys used on 2.9 million different devices. In Burma and Nigeria, tens of thousands of numbers shared the same key, pointing either to faulty implementation or outright fraud. They even found twenty American numbers that use a private key composed only of zeros. In detail. The method is not limited to confirming the existence of the accounts. For each one they extracted public keys, timestamps and the list of linked devices. This allows you to build detailed profiles without accessing the content of the messages. The age of the device can be estimated by counting key rotations. The “popularity” of a user is inferred by the frequency of depletion of their prekeys single usewhich are consumed every time you start a new conversation. Researchers downloaded 77 million profile photos of the +1 rank (prefix for the United States and Canada) in a matter of hours. 66% of them contained recognizable faces. They also found disturbing status texts, such as those from traffickers listing prices, accounts business advertising drugs or publicly visible corporate emails from governments and armies. And now what. Meta has deployed probabilistic cardinality counters to limit how many unique accounts a user can query without blocking legitimate contact discovery. It has also restricted bulk access to status photos and texts. The researchers confirmed that the measures work in subsequent tests. But no countermeasures protect those who were already listed during the months in which the system has been wide open. The big question. For four months, from a university server without even hiding their identity, they looted practically the entire user base of the most used application on the planet without anyone at Meta realizing until they were explicitly told. If these researchers were able to do it under these conditions, who else did it before without telling anyone?

A Russian family lived isolated in Siberia for more than 40 years. He didn’t know about World War II or the space race.

In the cold, vast and desolate siberian taiga one would expect to find spruce trees, maples, streams and acres covered in frozen silt. Maybe (hopefully) some lone pso or wolf. What no one would include on that list is what he discovered around mid 1978 an expedition that flew over a mountain located more than 240 km from any human trace. There, in the middle of the Abakan mountain rangea group of geologists came across a family that had been isolated for 42 years. Its story still fascinates today. And that cabin? Such a question must have been asked 47 years ago by a group of Soviet geologists flying over the Siberian taiga, an area rich in oil, gas and mineral reserves. He ran summer of 1978 and the team, led by Galina Pismenskaya, was traveling by helicopter in a region of Siberia located 160 km from the border with Mongolia when the pilot saw something between the trees. Something unexpected. A rudimentary cabin with a small garden. In most parts of the planet, such an image would be of little interest, but Pismenskaya’s team was supposedly in an unpopulated area. In fact, the Soviet authorities were not aware that anyone lived there. The nearest houses were supposed to be more than 200 kilometers away, so the question was obvious… What the hell was that shack doing there, built next to a stream, among trees? They were so intrigued that geologists decided to land. “We come to visit”. The impressions of Pismenskaya and her colleagues when approaching the hut we know them thanks to Vasily Peskova Russian journalist and traveler who would later interview the protagonists of that story to collect it in a book. Upon landing, the researchers found a hut made with the little that the taiga offered: bark, branches, trunks and pieces of wood blackened by humidity. On one side there was a tiny window. On the other side there was a door through which an old man appeared. “Like something out of a fairy tale”, would relate some time later Pismenskaya, who recalled that the man was barefoot, was wearing a patched shirt and pants and sported a scraggly beard. “He seemed scared. We had to say something, so I started: ‘Greetings, Grandpa! We’ve come to see you.’” The fact is that that old man was not alone. When they entered the hut with him, the geologists discovered that he lived with his four children. They all shared that wooden construction without rooms, blackened by smoke, cold and with the floor covered in shells. Upon seeing the new arrivals, one of the young women began to pray, scared. Another, hidden behind a post, ended up collapsing from suffocation. Logical. The family had not seen another human for four decades. Dating back to 1936. The old man in question was called Karp Osipovich Lykov and the fact that he lived there, in conditions almost medieval people, hundreds of kilometers from any hint of civilization and surrounded only by his children, is explained in light of what happened in Russia at the beginning of the 20th century. Just like his Karp family was an old believera member of a church split from Orthodox Christianity that embraced the ancient liturgy and ecclesiastical canons. The path of Karp’s coreligionists had diverged from the Russian Orthodox already in the 17th century, after Nikon’s reformwhich made them outcasts. This had happened in times of Peter I…and with the Bolsheviks. This harassment affected the Lykov family directly. Around 1936, a patrol shot his brother on the outskirts of the village where they lived, so Karp made a radical decision: he gathered his wife Akulina and the two children they had at the time (Savin, nine years old, and Natalia, two) and escaped into the forest. Literally. He walked away as far as he could. Without looking back and with light luggage that included just a handful of seeds, a rudimentary spinning wheel, a couple of jugs to boil water and the clothes they were wearing. Once in the taiga, the family built a cabin with what they had on hand, set up a garden and continued with a life marked by isolation, their beliefs and deprivation. In 1940 the couple had their third son, Dmitry; and four years later the fourth and last daughter, Agafia, was born. Back to history. The Lykovs continued with that life until Osipovich’s helicopter located them in the summer of 1978. It may sound strange, but the family had settled in a particularly inhospitable place. No one saw them before because no one looked there. The marriage moved as he encountered difficulties, moving further and further away from the villages and towns, until settling at a point located more than 240 km of the nearest settlement. Not even the Soviet authorities were aware of the existence of that family. The consequences of that isolation are obvious. For the Lykovs, time, politics, science… stopped dead in 1936. The family did not know that Europe had been shaken by World War II, nor that man had stepped on the Moon in 1969, nor was it aware of the space race, the name Kennedy or the Beatles did not ring a bell… Some family members marveled at seeing a television or items as seemingly simple as matches or a roll of transparent cellophane. Fascinating yes, bucolic no. The Lykovs’ 42 years of isolation were, however, hardly bucolic. Their cabin was built next to a stream and the forest offered them wood, fruit and even game, but the harsh conditions of the taiga subjected them to a constant test. Especially the first years. Agafia even told how towards the end of the 1950s the family faced their peculiar “years of hunger”, during which they had to decide whether to eat the little they harvested or save some of the seeds to grow them the following year. “We were hungry all the time,” he admits. Years later the family suffered a frost … Read more

In the midst of the RAM memory crisis, Samsung takes a leap with its HBM4 memory. It does not imply good news for the pocket

We are in full RAM price crisis. The industry is a cake that three large producers share and the data centers and the artificial intelligence They want to eat the whole cake. Samsung is one of the companies that manufactures memory for consumption and data centersand will soon begin mass production of its latest broadband memory chips: the HBM4. Don’t throw the bells in the air too soon. HBM4. This technology represents a crucial advance in stacked memories. Its density allows double the bandwidth, key to transmitting more data per second, but they are also up to 40% more energy efficient than HBM3. In short: they consume less energy and have fewer bottlenecks, which translates into an improvement in data processing. Industry sources point out that Samsung will use the 10-nanometer D1c manufacturing process for the matrix of these HBM4 memorieswith an internal structure of 4 nm. It’s a more advanced process than the 12-nanometer D1b from its main rival, SK Hynix. In addition, it will achieve a data transfer speed of 11.7 Gbps compared to 9-10 Gbps of the current standard. Hello Nvidia. South Korean media they point that these new Samsung HBM4 modules they would have passed Nvidia certification testing and will be in february when the company starts mass manufacturing them. Where will they end up? Some to Nvidia’s new AI acceleration system, called Vera Rubinothers at the heart of Google’s seventh-generation TPUs. After these reports, the company’s shares they went up 5.3% in the Seoul market. The enemy at home. In statements To South Korean media, Samsung representatives have commented that they feel quite confident with a new product that will clear up doubts about the company’s ability to supply the demanding needs of data centers. The fifth-generation HBM3E memories were a bottleneck for the company, so major players in the AI ​​industry looked next door: SK Hynix. Also South Korean, she is the second leg of memory chip manufacturing. The third is the American Micron Technology, a considerable distance from the two South Koreans. A year ago we already told that SK Hynix had achieved enormous efficiency in the DRAM stacking process to create these HBM memories, which allowed it to be 8.8 times more efficient than Samsung or Micron and, therefore, produce more modules for an industry that never stops asking. Meanwhile, the two South Koreans were in a race for the development of the new generation HBM4, and Samsung seems to have struck the first blow. Of course, it is estimated that Hynix will also begin mass production of these new memories on the same dates. And the consumer… what? Well nothing. If you were expecting good news related to the price of RAM, it must be said that no improvements are expected. These HBM4 modules will go to Nvidia, but we recently commented that OpenAI had reached an agreement with Samsung and SK Hynix to supply with 900,000 wafers per month. It is the volume equivalent to 39% of the estimated global capacity… and only for one company. Translation? Bottleneck in the market, a manufacturing speed that may not meet that demand and more bad news for the user. We have seen that Micron has abandoned its Crucial brand for consumers in favor of RAM for data centers, and that Samsung and SK Hynix are focused on HBM4 memories en masse, although they are not used in consumer devices, implies that this is where they will focus on this lucrative AI market. In short: Samsung may be dominating the new generation of memories, but 2026 seems difficult for anyone who wants to build a PC, expand RAM of yours, buy a new mobile or even wait for good news from the Steam Machine.

Hotel chains are strengthening their loyalty programs for a reason that has nothing to do with hotels: AI

Marriott, Hilton and Hyatt, three of the largest hotel chains in the world, are accelerating their loyalty programs to get direct reservations, he explains Financial Times. The immediate objective is to save the 15-25% commissions they pay to Booking or Expedia, but the real concern is another: to prepare for when AI agents book trips for us. Why is it important. Who controls the relationship with the client when the AI agents become widespread will control the business. Hotel chains have seen this movie before: This is what happened to e-commerce stores that sold directly, but were disintermediated by Amazon Marketplace. Or to the bloggers who went from publishing on their own websites to platforms like Substack, which promised range and parne. Or the developers who went from selling software directly to depending on the Apple and Google stores. Or, ahem, the media that lost control of distribution to, basically, Google. The facts. Hotel chains are promoting their programs: Marriott Bonvoy reached 260 million members in September, up 18% from a year ago. Hilton is making it easier to access higher tiers while partnering to use points outside of its wallet. Marriott’s CFO has already stated that AI bookings “could be cheaper than OTAs.” Translation: they prefer to pay commissions to OpenAI than to Booking. But only if they maintain control of the data and the relationship with the customer. Between the lines. The obsession with loyalty programs has its logic. If they can get 260 million people to be “Bonvoy members” with registered preferences and accumulated points, when the AI ​​agents arrive they will have to count on them. Or so they hope. Because this strategy assumes that AI agents will care about brands. But maybe not. Yes, but. A really useful conversational agent will scan all the available offer, compare prices in real time, read thousands of reviews and book. Without needing to see any interface. Without the brand mattering too much. Optimizing for price, location and reviews, not whether it’s a Marriott or a Hilton. If the customer never sees the brand, many decades and many dollars invested in brand recognition evaporate. The big question. Who will we trust more: Booking, which we know charges the hotel a commission, or an AI agent whose incentives we do not know to take us to one place or another? At least current platforms are transparent: they charge the hotel and you pay for what you see. With opaque agents making decisions for us, we won’t even have that. In perspective. This pattern will be repeated in dozens of industries. Insurance comparators, marketplacesrestaurant reservations, investment selection… Any digital intermediary whose value is “helping you choose” can be replaced by an AI agent that chooses for you. Hotels will not be the only ones building loyalty walls. Any company whose contact with the end customer is intermediated by digital platforms should be preparing. Because AI agents won’t arrive in five years. The first ones are already here, clumsy, but improving every quarter.
