zone

there was a “hybrid zone” of 4,000 kilometers

by

For years we had a fairly clear narrative in our minds of what had happened to our ancestors. The specific story is that the Homo sapiens They left Africa, met some Neanderthals somewhere in the Middle East, had a couple of chance encounters of hybridization pulses and they continued on their way to conquer the world. A change. However, a massive new study that just appear on the bioRxiv preprint server suggests that that picture is too simplistic. They were not specific meetings, but rather a continuous interaction throughout a huge “hybrid zone” which spanned from the Near East to Central Asia and Europe. To get here, the study has analyzed an unprecedented amount of ancient DNA to draw the most detailed map to date of how we intermingled with our extinct cousins. and the result It is a gradient of miscegenation which extends for almost 4,000 kilometers. Lots of volume. The study has not been limited to a few bones that have been found in isolation, but has used computer simulations and a data set of 1,264 paleogenomes. Something that corresponds to thousands of individuals older than 10,000 years. Your conclusion. The Neanderthal DNA patterns that we carry today in our genetic material They are not well explained by “isolated pulse” models, but rather the symmetry found between the genomes of Europe and Asia indicates that there was prolonged contact. In this way, as modern humans expanded out of Africa, which is what we know as Out of Africa, about 60,000 years agowere pushing a demographic frontier. On this advance front, gene flow was moderate but constant. That is why it was not a one-day event, but a long geographical process. The how. To understand this you have to look complementary studies which suggest that the key is in spatial gradients. To visualize the concept, we can imagine a wave that advances as if they were the Sapiens who were moving and encountering the Neanderthals. But the key is that Neanderthal ancestry is not uniform. This means that the first sapiens in Europe had a high level of Neanderthal DNA, but later expansions, such as the arrival of Neolithic farmers from Anatolia, they “watered down” that Neanderthal heritage, especially in Europe, creating a notable difference with the populations of Asia. This is where the study presented in 2026 confirms that only a model of persistent expansion with gene flow can explain why we find signs of interbreeding almost 4,000 km from the point of origin in the Near East. When did it happen? This is where things get interesting when crossing the data with other recent studies, like the one published in Nature in 2024. And although the area was large, the time window was critical. Analysis of more than 300 early human genomes points to a “single window” of major hybridization between 47,000 and 43,000 years ago. This excludes previous theories that suggested multiple, very ancient pulses. And to go a little further, there was a moment, when our species was securing its dominance in Eurasia, when the barrier between species blurred across a huge geographic swath. A map of interactions. What this body of research suggests is that the hybrid zone encompasses almost all of the Neanderthal sites known as Western Eurasia, so it implies geographically extensive interactions. However, as is often the case in science, caution must be maintained. This study has yet to undergo a full review and has limitations in that it is based on demographic assumptions and that it does not model the natural selection that we have in the genetic world. Even so, the image is increasingly clear: we are not the result of one species that replaced another suddenly. We are, in part, the result of a long border of contact where, for millennia, the line between “them” and “us” was much more blurred than we thought.

force the United States out of its comfort zone

by

If today we were asked which country is leading the race for artificial intelligence, the most immediate answer would probably still be the United States. And it wouldn’t be an occurrence. For decades, the country has set the pace for technological innovation and a good part of the digital tools that we use daily come from their large companies. However, that leadership is no longer as incontestable as it once was. The board begins to move and there is an actor who is closing distances at a speed that is difficult to ignore. That actor is China. The question is no longer whether China competes, but how it got here. How a country identified for years as the world’s factory, associated with mass production and cheap labor, has become a benchmark for innovation and technological vanguard. In a new video from Xataka’s YouTube channelour colleague Francisco Franconi analyzes this process in detail and puts figures, context and nuances to a phenomenon that we are seeing develop almost in real time and that can alter the balance of power in the global technology sector. China is no longer just the world’s factory: it is building its own path in AI “China should be years behind the United States in the development of AIs. It is a fact, since between 85 and 95% of the global market of chips used in this sector belong to Nvidia,” explains Franconi. The data is key, but it does not explain everything. The race for artificial intelligence is not only played in the field of semiconductors. There are other structural factors that are equally determining, and one of them is energy. The video delves into the enormous energy gap that separates both countries and why this aspect is crucial to understanding Chinese progress. As Franconi points out, energy “is necessary to build chip factories, supercomputers and processing centers. Without it there is no industrial growth.” To contextualize this statement, the analysis uses data from the International Energy Agency that helps to measure the real scope of this advantage and its direct impact on industrial and technological development. Another of the axes of the video is resilience. Specifically, China’s ability to adapt and continue moving forward despite the sanctions and restrictions imposed by the different US administrations. Franconi focuses on the repeated limitations that affect NVIDIA, but also examines the case of Huawei and the role that startups such as deepseek in this new scenario. Talent appears as another of the fundamental pillars of this career. “A relevant fact is that China has a greater number of graduates in science, technology, engineering and mathematics, but the most shocking fact is that 50% of the world’s AI researchers are of Chinese origin“says Franconi. A figure that helps understand why the Asian country is gaining weight so quickly in development and research in artificial intelligence. The video also covers the current ecosystem of language models competing in the market and offers a clear snapshot of the position that China and the United States occupy in this technological race. An analysis that leads to our colleague’s conclusions about where this global pulse is heading and what implications it may have in the medium and long term. You can see now the full video on the Xataka YouTube channel. And, of course, we invite you to leave your comments both there and on this article. Images | Xataka In Xataka | Huawei is coming back.

whether Galicia is in its zone or not

by

When on Monday, October 20, Pedro Sánchez advertisement that “the Government of Spain will propose to the EU to end the seasonal time change”, he did not suspect that he was about to reopen a much more arcane and unmanageable debate: that of Galicia and its time zone. And the Galicians are good when the subject is brought up to them. A historical claim. Internet is full of examples of this proverbial Galician anger. As they say, until 1940, Galicia (and, by extension, peninsular Spain) was in the zone of the United Kingdom and Portugal. It was a “temporary” measure that became permanent. And the consequences are more noticeable in Galicia because due to its geographical position it has very late sunrises in winter and extremely late sunsets in summer. “A scientific aberration.” In what we have been doing for centuries, the Galician Nationalist Bloc has promoted again and again the proposal of place Galicia in the same zone as Portugal. What’s more, in 2016, all the Galician parties asked that Spain returned to Greenwich zone. Without much success, really. And, despite the fact that it has been defended and studied a lot, the national response It’s been a permanent no. Because? Let’s go in parts, because this has a nutshell: during the Second World War, practically all of the countries of Western Europe changed time zone. In some cases, it was because of the invasion of Nazi Germany, yes; In others, it was a (more or less) voluntary decision by the different countries. Be that as it may, one after the other, they all switched to Berlin time. However, that is not what is striking. After all, in war situations, exceptional measures are taken. What is really striking is that, after the War, none of those countries returned to their previous zone. Not just Franco’s Spain, no: everyone. And the explanation, although it may not seem like it, is much more solid than it seems. But let’s talk about time zones… When in 1912 is celebrated the ‘Conférence internationale de l’heure radiotélégraphique’ and the 24 time zone system was approved, the lecturers turned to a very specific (and very useful) astronomical phenomenon: the fact that noon is stable throughout the year. That is, noon occurs almost every exact twenty-four hours and, therefore, establishing the time of each place in the world (adopting the time zone) turned out to be something really simple and revolutionary. Satisfied, they returned to their countries aware that they were making history. The whys were very clear… Although the First World War meant that the international time convention was not ratified by its members until 1919, everyone seemed convinced. After Versaillesthe different countries began to progressively unify their schedules. It didn’t really affect us. Spain was on the Greenwich meridian since January 1, 1901, like most European countries, under the Meridian conference of 1884. But there were many countries that did have to make important changes. After all, having a different schedule for each city (as was the case until then) made everything much more complex than necessary. “Normalizing” and “standardizing” the time was a key element for the desired ‘boom’ in rail transport, airships and incipient aviation: coordination costs were beginning to be unaffordable. Martin Olalla Martin Olalla …but people had other ideas. Despite rationalist optimism, the greatest experts knew that none of this was a magic solution. In 1844, the “father of spindles” Sandford Fleming had already said that, “The adoption of correct principles of time reckoning will not change or seriously alter the habits to which they are accustomed. They will not lose anything of value. The Sun will rise and set and regulate all social usages. (…) People will get up and go to bed, start and stop working, have breakfast or dinner at the same current time intervals, and our social habits and customs will not change.” And, indeed, people continued doing their thing. The problem is that this “his” consisted of something strange: suddenly, we began to realize that societies did not establish their schedules around noon, but around dawn. The most curious thing that almost all the countries in Europe discovered when changing to the Berlin time zone is that, in reality, what they were doing was adapting the civil time to the one that citizens actually had. That’s why no one went back to the old spindle: because it works better. Martin Olalla How does it work better? The best way to summarize it is with a phrase: “in winter, when it is daytime in Ourense, in Madrid, or in Barcelona; it is not daytime in London.” In fact, it is even daytime in Las Palmas de Gran Canaria. This does not depend on the time zone, it depends on the fact that the sun illuminates the spherical surface of the Earth. Does it work better for all of Spain? During autumn and winter, yes. Without any doubt. In spring and summer, things are not so clear. During these seasons, the sun hits much less obliquely and this means that the sunset fits much better with the time zones. The result is that the imbalance that we carry causes nightfall in Galicia much later than would be “normal” or desirable. This is a real problem, of course. But since the central issue is the variability with which the sun affects these areas, it is also not clear that introducing an extra time zone for Galicia (in the portuguese way) or for the Balearic Islands (as has also been claimed) will solve all the problems. I would trade one problem for another — let’s remember that Portugal has been one of the countries least open to eliminating the time change. But in addition, it would generate many coordination problems and very few comparative advantages.

This is the “danger zone” we enter after the massive death of corals

by

The Earth has officially entered a grim new era. climate reality. According to a shocking new reportthe incessant increase in heat in the oceans has pushed the corals from around the world beyond its limit, causing a unprecedented large reef mortality because of this climate change. Something that is not good news at all. This event, according to scientists, marks the first climate tipping point we have passed as a planet, directly threatening the livelihoods of nearly a billion people. The report. This data has been collected in the “Global Tipping Points Report 2025”, prepared by an international consortium of more than 200 researchers. And the truth is that they are not at all positive, since they suggest that even in the most optimistic scenario, where global warming does not exceed 1.5 degrees Celsius above pre-industrial levels, practically all warm-water coral reefs will exceed a point of no return. This makes their loss “one of the most pressing ecological losses facing humanity,” although the disappearance of corals is only the tip of the iceberg. Experts point out that since 2023 we have witnessed how the temperature has increased more than 1.5 °C compared to the pre-industrial average. In this way, exceeding the 1.5 °C limit now seems quite inevitable and could occur around 2030, something that puts our planet on the brink of an abyss. What are ‘turning points’. These points are nothing more than critical thresholds. Once crossed, the climate system is pushed into a new paradigm, triggering effects that will go on in a chain. Specifically, we talk about events such as widespread death of the Amazon rainforestthe collapse of the Greenland ice sheets or the collapse of the circulation of Atlantic southern overturn (AMOC). The Amazon, in particular, is in a critical situation. The report warns that not only warming threatens the forest, but also the combination of this with deforestation. With 1.5°C warming, only 22% deforestation would be enough to reach its point of no return. The current figure is already at an alarming 17%. All is not lost. Despite the bleak outlook, the report identifies a silver lining, which is nothing more than a paradigm shift that, unlike the negative ones, triggers a cascade of beneficial changes. Since 2023, the world has seen very rapid progress in the adoption of clean technologies, especially in two key areas: velectric vehicles and photovoltaic solar energy. Accompanied by a drastic drop in battery prices, these factors are beginning to reinforce each other, accelerating the energy transition in a way that few anticipated. The problem. According to the report’s authors, it lies in governance systems. From national policies to multinational agreements, such as the from Pariswere not designed to address turning points. They are designed to manage gradual, linear changes, not abrupt, cascading collapses on multiple fronts at once. But these turning points are really threatening, so they point to a series of immediate actions to be taken in all countries to avoid a catastrophic situation. In this case they point to the following: Reduce emissions of short-lived pollutants such as methane and black carbon. Accelerate efforts to remove carbon from the atmosphere. Making global supply chains sustainable. Develop mitigation strategies for climate impacts. The message is clear and forceful: what we have done so far is not enough. Researchers urge not to look away. As Milkoreit concludes, “even having a reader have the courage to stay with the problem is work, and I want to recognize that work.” Images | quinguyen Chris LeBoutillier In Xataka | In the fight against climate change, we have developed the air conditioning revolution: ionocaloric cooling

Ukraine is basically a country made dron. So the war between humans has passed to an unpublished zone: underground

by

Of all the realities that war in Ukraine is showing us, there is one that has no discussion: drones are The Trojan horse on which they are going to sustain war conflicts From now on. In Eastern Europe we are Seeing scenarios that until recently they were more typical of Fantastic literature than reality. The prominence is such that the battle between soldiers is no longer getting rid of the ground. It is getting rid underground. The war in the bowels. Yes, Kharkiv’s front is being the scene of an unexpected phenomenon: Russian soldiers tried infiltrate pipes of gas and water, crawling through ducts Underground to overcome the Oskil River and establish positions closer to Kupiansk. It’s about The third time in which this tactic appears since the beginning of the invasion, and is a new defensive challenge for Ukrainian forces, which have reacted flooding, damaging and fortifying several of these passages, aware that the pipes form an extensive and difficult network to control. kyiv’s General Staff officially confirmed that the pipes had been used, although it stressed that the city remains under Ukrainian control and that most accesses have already been closely neutralized or monitored. Pipes such as espionage routes. Kupiank’s case is not isolated. As We count thenlast March, Russian special forces toured almost fifteen kilometers through a gas pipeline in Sudzha to throw a blow against the Ukrainian rear in Kursk, an episode that Moscow celebrated As tactical successalthough it ended with the annihilation of much of the infiltrated team. In Avdiivka, at the beginning of 2024, Russian troops They drained a pipe Water service and adapted it as a underground route, opening exits every hundred meters to facilitate the advance. These maneuvers, which evoke command operations of other warsThey take advantage of the industrial and energy fabric of Ukraine, a country crossed by large gas pipelines that for decades were key to the European supply of Russian gas and that today, to a large extent, are underutilized. The Ukrainian response. Before this Unusual threatUkraine has deployed measures from Creative Military Engineering. In Kupiansk, teams of the 429th regiment of unmanned systems used explosives to damage the point where a pipe crossed with the Oskil, causing its flood. In addition, wire wire have been introduced inside some ducts, with Videos that show Booby-Traped passages designed to catch or dissuade intruders. Although the controls They recognize that Russia could try to repair or reuse these passages, ensure that surveillance is constant and that each attempt will be answered. This deployment reflects how Ukrainian defense is not only fought on the surface, with drones, armored or artillery, but also a subsoil turned into a new front. The expansion underground. Plus: The war in Ukraine had already shown An underground face in the catacombs of Mariupol or in the trenches of Bajmut, but the use of gas pipelines and pipes A different dimension: abandoned industrial corridors that now become improvised military tunnels in fear that drones do not allow surface advances. With a diameter of more than one meter in some cases, they allow the passage of equipped men and even basic supplies. Its extension, designed to transport up to 140,000 million cubic meters of gas per year, constitutes a potential battlefield which multiplies the possibilities of infiltration and forces Ukraine to allocate resources to unexpected land. The paradox is evident: the same infrastructure that once connected Europe with Russian energy today are Combat scenarios where the immediate security of cities and defensive positions is played. Strategic implications. He Use of pipes as penetration routes Confirm two things. On the one hand, that drones have transformed What we understood as a contest so far. On the other, the Russian ability to exploit any loophole in Ukrainian geography, even undergroundtogether with the need for kyiv to develop multilayer defenses that cover from the sky, saturated with drones, to subsoils, now traveled by soldiers crawling into the dark. Beyond the punctual efficacy, These tactics They highlight the plasticity of contemporary war, where each civil infrastructure can be militarized and where combat is fought in secondary dimensions. For military analysts, the battle of pipes in Ukraine anticipates a future in which the defense of a country will depend both on the surface that its population inhabits, plagued with swarms, as well as on the bowels that run through its industrial networks, now turned into unexpected war tunnels.

The maps that explain why Castilla y León have become the “zero zone” of forest fires

by

The fires are a pressing problem every summer, but in the midst of the heat wave that shakes peninsular Spain, the problems derived from fire grow Without giving us breath. One of the areas most affected by fires is the northwest quadrant of the peninsula. Something that we can verify in a series of maps that show us the present and future risk of fire. Fire risk, from satellites. The Risk Management Service of Copernicus, the land observation system of the European Union, shows us on a map the Areas with greater risk of forest fires In the continent. The map shows the FWI fire meteorological risk index (Fire Weather Index), distinguishing areas with low, moderate, high, very high and very extreme risk. The map allows us to visualize the risk we face: a good part of the Northern Plateau, in addition to areas of the Cantabrian, Pyrenees, Galicia and other areas present in index greater than 2.5, which implies very extreme risk. Southern Europe, and beyond. The map covers not only peninsular and Balearic Islands, but also the rest of Europe and surrounding areas. In fact we can see in it that the very extreme risk situation extends not only to northern Portugal, also to most of the center and south of France. Other areas in this situation can be found in the Balkans, Greece, Romania, Bulgaria, Slovenia, Austria and Hungary. Important anomalies are also indicated in Nordic countries, such as Sweden, Norway and Finland. A problem that will go worse. The Copernicus map covers this week together, from day 11 to 17. However we can resort to other maps that allow us to see the evolution of risk during the next few days, Fire risk maps of the State Meteorology Agency (Aemet). What these maps show us is not an invitation to optimism. Aemet fire risk forecast evolution on August 14, 15 and 16. State Meteorology Agency. The stain extends. The extreme risk today focuses on Andalusia, Extremadura, the west of Castilla y León, and the Pyrenees, as well as areas located in Galicia, Basque Country, Murcia and other communities. However, tomorrow this area under extreme risk will expand both in the peninsular northwest and in Extremadura, the Basque Country and Murcia. On Friday and Saturday the “red spot” will continue to grow. On Saturday, only specific areas on the coast and in mountainous areas will be fought from the very high or extreme risk. The devastation of a fire. In addition to risk maps, Copernicus also allows us to visualize the ravages that active fires have already caused. Example of this It is the fire of El Arenal, in Ávila, which has already affected almost 1,800 hectares of surface.

install a nuclear reactor on the moon before China and Russia create its exclusion zone

by

The Space race has warm upthis time in the heat of a nuclear reactor on the surface of the moon. And as already happened in the 60s, the urgency is not scientific, but fundamentally geopolitical. The Duffy directive. The break between Elon Musk and Donald Trump trunciated Jared Isaacman’s career as future NASA administrator. The current acting administrator of the Space Agency, Sean Duffy, is in turn Trump’s Secretary of Transportation, faithful to the priorities of the White House. In a movement that will mark the priorities of the agency, Duffy has launched an accelerated plan to build a small nuclear power plant on the moon. The directive urges NASA to have a satellite functional reactor by 2030. Why 2030. The main motivation is get ahead of the Chinese and Russia Alliance to build your own lunar reactor. “We are in a race towards the moon, a race with China. And to have a base on the moon, we need energy,” Duffy explained In a later press conference. The fear of Washington is explicit in the directive itself: “The first country to do so could declare an exclusion zone, which would significantly limit the United States for establishing the Presence of Artemis If I will not arrive first. “ A new plan. NASA was already working on a project called Fission Surface Power (FSP) with the intention of installing a 40 kW reactor on the surface of the moon at the beginning of the next decade. The new directive, published entirely By NASA Watch, raise the bet to a more efficient Bryton cycle turns and a minimum power of 100 kW. The dates are also more ambitious. The United States government requires NASA to be installed for the first 2030 quarter using a launch system of at least 15 tons of capacity. The reactor and all transportation logistics and installation will be open to the American private industry through a future public tender. More astronauts, less science. Nuclear energy will be crucial for any manned lunar base. The moon has a day and night cycle of approximately 29.5 terrestrial days, which means that any type of lunar colony faces two weeks of icy darkness. Solar energy is unfeasible to feed the life support equipment and heating that will keep astronauts alive. A fission reactor, on the other hand, would provide a constant and reliable source of energy. This Directive is the first important movement of Sean Duffy as an acting administrator, and reflects the change of course that began the 2026 Budgets of the White House: an increase in the funds for human exploration of deep space, especially if they can prevent China from getting to Marsand cuts of up to 50% in purely scientific areasincluding many of the probes that study the solar system.

The intestine has a “golden rich zone.” And if we often default out of it you have to pay attention

by

Making peanut is a intestine health thermometer. So much that in Australia they encourage employees do your things at work. It is a moment that We can take even to read or to do Infinite scroll on mobile (Even for Share the site in which we are making poop), but also one that we should pay more attention. The reason is that the time and frequency are details that say a lot about our long -term health. Cause or consequence? Throughout the years different investigations have been carried out on the importance of defecation as such, but also about the ideal time to do sothe frequency of the same and the shape, size and texture that They should have The Depositions. Studies have been carried out that linked the constipation with a higher risk of infections and diarrhea Chronicle with neurodegenerative diseases. However, these observations were made in subjects who already had some disease, so it had to be found out if the intestinal problem was a cause or the consequence. As science is not done alone, a team from Institute for Systems Biology He took the front to answer that question. The study. In it studyresearchers are Gibbons and Johannes Johnson-Martinez analyzed the clinical, genetic, microbiological and lifestyle variables of 1,400 healthy adults. Something that the subjects had to detail was the frequency of the depositions, which would be classified as follows: One or twice a week – constipation. Three to six times a week – Low frequency. One to three times a day – normal frequency. More than three times a day – Diarrhea. “Gold rich zone”. The researchers realized that the people who reported eating a diet rich in fiber, exercised regularly and had good hydration, had a good intestinal movement. In a display of scientific humor, they baptized this as “the golden rich zone”, which becomes a frequency of intestinal movement between one and two daily stories. That is the point where, according to researchers, the balance between microbiome and physiological markers is optimal. Therefore, the optimal frequency is between one and twice daily, but it is not always the case and, when there is an imbalance is when the problems begin inside. Ideal form of feces: Type 3 and 4 More serious than it seems. Johnson-Martinez comments that “if the feces remain too long in the intestine, microbes exhaust all available dietary fiber, something that normally ferment to produce short-chain fatty acids beneficial for health. If this occurs, the ecosystem changes and begins to ferment proteins, which generates several toxins that can reach the bloodstream.” These by-products of the fermentation of protein filtered to the bloodstream, such as the sulfate p-rresol and the Indexil Sulfate, pass to the kidneys, causing damage in case of constipation. If, on the contrary, diarrhea occurs, feces practically do not go through the intestine, causing clinical parameters related to liver damage. That is: with constipation, the kidneys suffer. With diarrhea, the liver. Chivato. Gibbons comments that chronic constipation, which we have just seen what effects they produce, has been associated with neurodegenerative disorders and the chronic progression of kidney diseases. What is missing is to define whether that anomaly in the intestinal movement is an early warning of a chronic disease or damage to the organs. Now, the study also explores how this frequency of the intestinal movement is also related to the Anxiety and depressionrelating mental health to deposits. The researchers comment that it has been possible to link the frequency of the depositions with all body systems and how is something that can be a risk factor in the Chronic disease development. His hope is that medicine be taken seriously to “optimize health and well -being, even healthy populations, based on the frequency of intestinal movement.” And some drawer is that, if we have no problem, we should not hold the desire or force it, because we reduce and artificially increase the time that the feces are in the intestine Study feces. There is an important detail that must be taken into account: to have a different frequency from that of one/twice daily can be normal. The problem is when it becomes chronic. That is when we should ask ourselves what is happening. There may be a health problem, but also that we have a low diet in fiber from fruit and vegetables. It is logical, but food and Our lifestyle It is something inseparable from our feces. In addition, throwing an eye from time to time is not a bad idea because it is a free intestinal health test. Also You can scan your poop with an app that analyzes it thanks to the AI. The time, matters. Being in the “golden rich zone” is relevant, but previous studies also explored the idea that the moment we make peanut is also. Studies prepared in 2020 and 2022 They related circadian rhythms to gastrointestinal activity. At night, intestinal activity decreases significantly, but during the day, especially after waking us or eating, there is greater mobility. An optimal moment is half an hour after awakening, since the colon is activated after nighttime rest, but defecating later of that moment does not imply that something goes wrong because there is some flexibility in the matter.
