Finance Mines Today, its production is ensured tomorrow

by

Recently The news jumped that Europe did not want to buy Chinese solar panels if they had been developing through forced labor. The problem is not only manufacturing, but the Asian giant controls the entire supply chain from its extraction to its refinement, taking almost two decades of advantages. And now it goes one step further: now you want to ensure future gold production. A new opening. Zijin Mining Group, one of the world’s largest gold and copper miners, has begun to open its funds to professional investors in Hong Kong. According to Financial Timeshas launched the first background of streaming China Minero, a financial modality that consists in finance mines in exchange for rights over its future production. With this model, traditionally dominated by Canadian companies such as Wheaton Priceus Metals, Zijin intends to ensure ingots without directing each mine. But the play does not end there. As He has reported South China Morning Post (SCMP), Its asset management subsidiary, Gold Mountain Asset Management, has gone from operating exclusively with internal resources of the group to capture external capital, offering exposure to strategic metals such as gold and copper. A strategic movement. The decision is not fortuitous. On the one hand, the offer is increasingly limited. Both Lisa Liu, director of Gold Mountain, and Bank of America analysts cited by Financial Times They have agreed that the gold mines in the world are depleting their high quality reserves, while investment in new explorations has been insufficient during the last decade. On the other hand, the demand for gold does not stop growing. In times of geopolitical uncertainty and commercial tensions, central investors and banks take refuge in tangible assets. This has driven gold to mark historical maximums. According to SCMPsome experts have estimated that the price could reach $ 4,000 per ounce this year. The center of the world. The digital transformation of the Asian country is not accidental. In an increasingly bound world towards data centers, electrical networks and artificial intelligence infrastructure, China wants to be where you should be. Has already shown it by configuring as The first “electrostate”and now seeks to ensure access to basic materials that feed that infrastructure: gold, copper and also lithium. Gold always shines. As They have detailed In SCMP, Zijin’s funds have reported a performance of 18% only in the first four months of 2025, and Copper investments They are also outlined as strategic to the growing demand promoted by artificial intelligence. Zijin even plans to reorganize his international assets under a new entity, Zijin Gold Internationaloverlooking a future stock market. In addition, Gold Mountain directly finances mining projects through private credit, accepting in return the gold produced, a way of ensuring supply without the need to operate the deposits. Has also signed agreements of streaming With mines in Ivory Coast, Gansu (China) and hopes to close new operations in Africa and South America, According to Financial Times. A broader ambition. Beyond the numbers, what Zijin is building has a geopolitical dimension. In an increasingly fragmented world, where critical resources define technological and energy sovereignty, controlling the flow of gold, copper and lithium is both an economic and strategic play. While the West continues to discuss decarbonization or industrial relocation, China is buying the subsoil. Gold by gold. Mine per mine. Contract contract. The future of energy, technology and security may not be alone in algorithms, but in the metals that make them possible. And China is making sure they go through their hands first.

We have been thinking for 50 years that lemmings are rodents that commit suicide. The guilt of everything has Disney

by

If they mention the lemmings we will immediately think of The legendary action video game and puzzles of Psychnosis of 1991. The mechanics of that game, in which the herd of creatures obeyed us blindly, even opting for sacrifice, have a specific origin: a Disney documentary. But … what if everything he told were not only false, but orchestrated by the filming team itself to obtain images of the lemmings suicide? What is a lemming (really). A Lemming It is a small rodent that usually lives in areas near the Arctic or in Biomas de Tundra. They are similar to field mice and musk rats. They measure between 13 and 18 cm in length, they have very short tail, chubonch and hairy snout, short legs and small ears. With a garrita on the front legs they dig into the snow. They are herbivores and live in large tunnel systems. And no, against what is said, they do not have a docile attitude and a flock behavior: although they move in a group by the very high demographic explosions they experience, they are aggressive even with the predators. What was believed to be a lemming. That demographic explosion (which actually obeys mere survival: The reproduction cycles are short and the very fertile females to compensate for the attack of predators and the shortage of food at certain times) is precisely what the 1958 documentary ‘white hell’ was inspired. Produced by Disney, this production talked about how, due to the multitude of offspring that they have since there are not enough resources to maintain them, the lemmings are sacrificed for the good of the population and threw themselves by cliffs, committing suicide. The film even offered images of the moment. The origin of the myth. Long before the filming of ‘Blanco Hell’, Rumorology around Lemmings was abundant: In the 16th century, the Bavarian geographer Jacob Ziegler defended that these rodents fell from heaven when there was a storm and died when the grass grew in spring. This thundered statement was based on local folklore: being the Arctic fauna, the native populations of Inuits or Yupiks had their legends around the lemmings, similar to those of the geographer. Little by little, science was denialing this almost celestial origin of rodents, although for centuries it was believed that the herds were traveling transported by the wind. In pop culture. Science fiction and fantasy was the one that possibly grabbed this idea of ​​the lemmings that moved by air and transmuted it into bugs that commit suicide throwing themselves into the void. Since the fifties we find precipitating Lemming in works such as the story ‘The march of the fools’ of Cyril M. Kornbluth, of 1951, where the lemmings with space travelers who march to Venus to die in a collective suicide are compared. A legend of Disney comics, CARK BANKShe drew in an adventure of the ducks to Lemmings jumping through Norwegian cliffs. And nothing less than Arthur C. Clarkein his story ‘the possessed’ explains with a case of alien group possession the behavior of rodents. What really happened in the documentary. The director of ‘Blanco Hell’, James Algar, I intended to record an authentic sacrifice of the Lemmingsbut he did not look like. So the photo director came up with a group of local children to hunt Lemmings, 25 cents the piece. Once they had enough, they were cleared them. A cruel resolution (nothing strange in Documentaries about animals of the time), but today is somewhat uncomfortable to see: ‘Blanco Hell’ went on to accompany other Disney films to which time has not treated very well, and was withdrawn from Disney+ together with classic cases such as The racist ‘Song of the South’. In pop culture. And thus the myth was founded, which gave us an extraordinary video game and a wrong belief in the popular culture that persists until today, as the same Begoña Villacís demonstrated, which in 2017 signed in the confidential an article entitled ‘Catalonia, an army of lemmings‘. Although few stories as fun around the nice rodents as an article of ‘Popular Science Monthly’ that, in 1877, said that suicide lemming what they want is to throw themselves into the Atlantic to immerse themselves in search of the lost continent of Lemuria. Damn rodents. Header | Wikipedia, Psygnosys In Xataka | The amazing video that shows an octopus by changing color while you think is dreaming

In 1958 we found a skull with 300,000 years in China. The problem is that we do not know what “homo” belongs

by

It all started a 1958 day when some peasants from the province of Guangdong in China were collecting guano of bat in a cave and noticed something unusual: bone remains that looked like a human skull. They warned local researchers, who cataloged the piece and baptized it with the name of the nearest people, Mabaand the number ‘1’. When did this be live? At some point in the period between 130,000 and 300,000 years ago, and the big question to answer was to what extent It was our ancestor. A recent study already has the answer. More or less. The ‘Chinese Neanderthal’. You will be wondering how such an extremely open temporal fan is handled, and the answer is that it is complex to perform a more precise dating due to complexity of both the site in which it was found and the features of Maba 1. At first, the specimen was nicknamed as’ the Chinese Neanderthal‘Due to cranial similarities with that species, but other studies have dismantled that hypothesis, bringing it closer to homo. It does not fit. But there was still a problem: facial similarities and microtomography analysis rule out that it was a neanderthal, yes, but it is not fully fits with a Homo erectus or with the Homo sapiens. Either with those Denisovanosand the problem is that it can be many things. Facial features, such as nasal prominence, brings Maba 1 to Neanderthals, but the neurocranium It has similarities with Homo Heidelbergensis and Homo Erectus. However, the cranial volume is comparable to that of modern humans and everything adds to a set that is very different from other Chinese fossils of the Pleistocene. Summary: We have no idea. Seeking to learn more about him, the authors of A new study carried out by researchers from the Institute of Paleontology and Paleantropology of Vertebrates of the Chinese Academy of Sciences analyzed the cranial cavity, the diplus vessels and the rest of the internal structures of the skull. Using the technique of tomography, researchers discovered that MABA 1 does not belong to a single class: it belongs to many. And the truth is that it is not so strange to find hominids of this period that they do not fit completely into established categories. No, it is not a “lost link”, at least not in the most colloquial sense, but it seems to be an individual belonging to those cases than They blur the limits between different species human 3D reconstruction of the skull for study But it teaches us something. This whole case reminds me of the episode of ‘The Simpsons‘In which Lisa finds the skeleton of an’ angel ‘and takes a piece to the local archaeologist to investigate it. After the evidence (which we later knew he did not make), his conclusion was that the results were not conclusive. With Maba 1 something similar happens, but it does leave us an important lesson. The researchers comment that “the internal structures of MABA 1 show a combination of morphological characteristics found in several species. And these findings further evidenced the high morphological variability among Asian hominids in the middle pleistocene.” In fact, Maba 1 is a perfect example of that complexity in the human evolution that we commented, since the mixture of features reminds other contemporary fossils found … in Africa. Researchers are clear that “currently, it cannot be definitively classified in any known hominid taxon”, but also that it remains a key fossil to understand the diversity of the hominids of the Middle Pleistocene in Asia. At the moment, it is not a Neanderthal and, now, we also know that it is a “no erectus.” We will see what happens in future investigations, but Maba 1 is not unique.

The links have been from the beginning the basic unit of communication on the Internet. AI is exterminating them little by little

by

In March 1989 Tim-Berners Lee published The proposal that would define the Internet and the web as we know them today. This document based everything on hypertext, “readable information for human being and linked unlimitedly.” The basic internet unit and the web. The links soon became that cement that linked all the information and connected it. They allowed to jump from a content to another, and that led us to that original chaotic, anarchic and wonderful website. And Google arrived. This giant triumphed where others did not just do it. The martemágnum of content and information needed a certain organization, a certain order, and Google built its empire by responding to that problem. For many years the company was clear exponent of the value of the links: its own results page was an ode to that concept. They were basically links. That was wonderful, and Google was even able to understand the impossible and to know that when we were looking for “waterchu bi fri” The video we wanted from Queen. A “prominent fragment” or “featured snippet” by Google. Fixed: it is not very different from the answers generated by AI, although in this case Google simply copied and glued párara from the original source, which linked at the bottom of that box. You don’t need (so many) links. Over time, the approach changed and Google tried to lock us more and more in its search engine so that we would not leave it. It was about answer our questions directly With his “featured snippets” (“prominent fragments“), the small text boxes that appeared when making certain searches. This system was fantastic for the user – which many times found the answer he was looking for – and for Google – more retention, more advertising he could show – but not for the original creators of those contents of which Google” stole “the information. The 1989 Berners-Lee document already pointed to hypertext documents with links as a fundamental component. Hello, web. Source: W3.org. You are taking advantage of my work. That, among other things, ended up causing an angry protest by media and content creators, which demanded Google News and other links of links that paid for the contents that copied and linked. It was the first iteration (there is another different and more recent) of the “Google Rate“And the Canon Aede included as part of the Intellectual Property Law. That didn’t end well: Google News hill In Spain For 8 years because Google and others forced them to “pay to link.” The service returned with an iceta law that allowed Google dodge those payments and negotiate case by case to reach agreements. It is curious how seven years ago who subscribed claimed that Google and Facebook did have to pay for those contents, and now be The same thing with the AI. But I’m getting ahead of the matter. Toxic links. The evolution of the Google search engine, which previously represented the maximum exponent of a website in which the links were its main value, has been worrying. For many of us Google has broken its own search enginenot to go against the links, but to contaminate them. SEO and sponsored links have ended up taking over the experience, and that was already an important blow to the web. We did not click not because there were no links, but because we did not fix too much from a results page that is too manipulated. The Huffington Post (now, the Huffpost) was born in the face of Facebook. They survived; Others like Buzzfeed no. Social networks were good before being bad. The arrival of social networks caused the links to be even more important, and in fact we live an explosion of content – and a lot of clickbait – and the birth of the cult of Facebook by media Like the missing Buzzfeed. Then they realized something: sending people to external websites was not interesting. The interesting thing was to keep users locked on your platform. Facebook can be criticized many things, but at least the platform never stopped using links. A cousin of his was born with a much more perverse attitude. Instagram and open war against links. When Instagram was born he did it as a fantastic Flickr successor and other services for photographers. Soon it became the epitome of “A picture is worth a thousand words”, and although it was possible to accompany each image of a text, what was prohibited was to include clicking links. Except in very specific sections (Like the bio of the user), link was and is strictly prohibited. It was unusual. Social networks as walled gardens. Soon the social networks realized – as before Google had done – that the links were against them, and that the best thing they could do was lock us all in their respective walled gardens. What Instagram raised was just the principle of a worrying derives towards those silos of algorithmic content: Tiktok That line followed and only some verified users can include links to their videos. Twitter, who was born as a platform to share reflections and links, also changed with the arrival of Elon Musk, andNemeligo declared of the media. The tycoon arrived APRoibrate links to other social networks, and then CHe would ontaminate the experience With its algorithm in addition to DIt is to keep the links In X because “they don’t attract so much attention.” Or rather, so that you were not from X. Snapchat, somewhat less popular but equally relevant, also raised an aggressive policy against links. Offers limited options To share links, and their absolute focus on mobiles (and not to the web and their links) is patent: he launched its web version in 2022, 11 years after its creation. AI arrives. The role of the links has therefore been co -fled on platforms and social networks, and what we already saw with Google and its Snippets now threatens to be the norm in the chatbots that They … Read more

First steps to release your new Korean brand phone

by

Let’s tell you What are the first steps when premiere a Samsung Galaxy With One UI 7, the new version of the customization layer of the Korean company. This version will gradually reach many brand phones, although you have a high range like the Galaxy S25 You already have it available. What we are going to offer is a start guide with those first steps and initial configurations to which you should pay attention. The goal is to leave the mobile ready already to start using it having it already adapted to you. Initial configuration The first when you light the mobile is to put yourself with the initial configuration. The welcome screen can appear in several languages, but to start you just have to click on the only button, and then Choose the language What do you want to use. Then comes the turn of the privacy policy, where you can accept two things. Here, it is enough to accept the end user license agreement, and you do not need to accept data sending to continue. Then you go to the key point, the Configure your mobile from another device. Here, you will be able to do it from another Android mobile, from an iPhone or not do it and continue manually. To use another Android mobile or tablet, a QR is generated from which the connection is established, and from iOS you will have to use the Smart Switch app. In both cases, you can easily migrate your passwords, configurations, session and other elements. In the event that you do it manually, you will have to choose and connect to a Wi -Fi network, and then configure the mobile network. Then, you will also have the option of Copy applications and your data from another deviceand you will continue to start session with your Google account. Below you can choose methods to block the screen. Here you can configure elements such as your footprint, facial recognition, a pin or a pattern. When you finish it you will have to continue configuring Google services, where you will determine what data you share with the company. It is worth spending for a while to look at this. And then, you can configure some of the default applications. Here in Europe the manufacturers must do it, so you can Choose the browser or search engine What do you want to use. At the end of the process, you can configure your Samsung account, starting with one that you already have or creating it. Then you will only see the information of Galaxy AI and Bixby, in addition to the Samsung. And to finish, you have to choose between clear or dark mode on the mobile and ready, you can start using it. Choose what applications you install This is possibly the most tedious step of all the tuning of your mobile. Once you have it, you have to install all the apps you want to use. This means that you must enter Google Play and lower your applications. If you have already used the same Google account with other mobiles, click on your application store profile, go to Gesting apps and devicesand in the tab Manage You can access the apps you had installed on other devices. If you have configured your mobile to extract the data and applications from another, then the task is facilitated by lowering the majority of apps you were using. Even so, It should be reviewed that you are always use To leave everything downloaded. DESCARORY CONFIGURY AND FAST SETTINGS Next, the time comes to customize the appearance of your galaxy. For that, once all applications must be installed Configure the appearance of the desktopdeciding what apps there are on each of its screens, their position, the widgets and which ones remain alone in the application drawer. After that step, although this is already more advanced, you can also Set the fast settings panelto determine what settings appear when you open it. Here, go to the control panel and click on the pencil icon above, and you can relieve the buttons and add others to your liking. Customize the appearance of the mobile Once you have put in order the main customization of the mobile, you can spend some time in other aspects. For example, You can apply topics or simply change the wallpaper of your device to give that special touch that we all want. Both options are in the adjustments. You can also edit the lock screendeciding if you want to use mode Always on Display or always on to have some data such as the clock or other elements without having to turn on the screen. In addition, in Sounds and vibrations can change how and how much your mobile sounds. You can remove sounds such as the keyboard, choose the call tone or the sound of notifications, configure the intensity of vibrations, and ultimately everything related to this. It is worth dedicating five or ten minutes to make the mobile behave as you want. If you enter the screen options, you can choose between clear or dark mode, and many other aspects such as resolution. Here, it is important decide between buttons or gesturesthat you will find within the section of Navigation bar. They are the two ways in which you can handle yourself on Android, and it is convenient to explore them to use the best. And somewhat more advanced are the home screen settings, where you can configure the grids that the desktop and apps have, if you want a balloon to appear with the number of pending notifications on the icons, or even the size of the icons of the applications. Set the Now Bar One of the main novelties of One UI 7 is the Now barwhich is a bar on the blocking screen where you can directly control from it some applications without having to unlock the mobile. You can pause recordings or move on to … Read more

Jared Isaacman has been separated after Elon Musk out of the White House

by

Everything was ready for him Multimillonario Jared Isaacmanwhich has flown twice to Spacex space, take NASA’s helm. The Trump administration withdrew its nomination the same day that Elon Musk left the White House. They have kicked him. According to The Washington PostIsaacman was informed on Friday that his nomination as a future NASA administrator, which was made public in December, would be rescinded, despite having already received the approval of the Senate Committee. “The last six months have been enriching and, sincerely, exciting,” Isaacman wrote in his X profile After making the news public. “I have acquired a much deeper understanding of the complexities of the government and the weight that our political leaders have. The President, the NASA and the American people deserve the best: an administrator willing to reorganize, rebuild and bring together the brightest minds to generate the headlines that change the world.” What happened between scenes. Isaacman was seen as An accelerationist of lunar and Martian missionswilling to face China in exploration of the solar system with a smaller budget Thanks to the public-private collaboration. But also as an obvious partner of Elon Musk; recommended by the businessman himself, Despite the conflict of interest. The White House issued a statement with some clues on Saturday: “The mission of President Trump to plant the US flag on the planet Mars” is still standing. But Isaacman was not sufficiently Trumpist, And the cut passed by the influence of Muskwho had donated 275 million dollars for Donald Trump’s campaign: “It is essential that the next NASA leader is in complete alignment with the president’s America America Agenda.” The lowest budget in 65 years. The historic cuts that, if approved by Congress, would reduce NASA’s budget by 24%, have been part of the problem, as Jared Isaacman, like Musk, positioned himself against eliminating scientific missions, the most affected. Isaacman would have had to direct NASA with the lowest budget since 1961. The presidential proposal for 2026 raises A cut of almost 47% For the entire agency science division, from 7,334 million dollars to a few 3,907 million. This massacre would be the immediate cancellation of up to 40 missionsmany of them active and other future, crossed out of “low priority” despite NASA’s efficiency in this branch. Who will be NASA’s boss. Donald Trump will announce it shortly, but Ars Technica He publishes that there is a candidate in consideration: the former Lieutenant of the Air Force Steven L. Kwast, a politically loyal military to Trump who “seems more oriented to see space as a battlefield than as a place for peaceful cooperation and exploration.” Until it becomes official, NASA’s future is a great unknown. In any case, Isaacman’s departure does not seem to be linked to the Boeing and Lockheed Martin lobby, which is working at full speed after the cancellation of the SLS rocket and the Orion ship. “If Kwast is the candidate,” says journalist Eric Berger, “he is definitely not in favor of the traditional space industry, he is a firm defender of the commercial space industry.” Image | Spacex In Xataka | A millionaire has just arrived where NASA had arrived.

China is attending a crazy race to demonstrate who has the safest battery. That’s why they crush them with tanks

by

If I point to the volume, I am not sure if I learned a lot or little in the university. But I am clear about one thing: I learned what was news or, at least, the criteria to point out whether an event is news. When the issues that can be discussed are put on a wording, different aspects are valued. Truthfulness, current, proximity … and novelty. And if an event comes out in the media it is because it is usually “unique, unpublished, unlikely or out of the ordinary.” I don’t say it, University institutions say. That is why it makes little sense to affirm that electric cars are dangerous based exclusively on news. We could do it if we had relevant studies that pointed out that the number of electric cars is notoriously higher than those of combustion. But it is not the case. We do know that the fire of an electric car is more complicated to turn off and more virulent. That is why it is logical that take action on ships where they are transported or working on New protocols in fire bodies. That does not mean that the risks of this technology are greater. In spite of everything, it also enters within a certain logic that when a fire is given or any other risk situation, the alarm voices are multiplied. From municipalities where They consider whether to continue buying electric cars a parking lots that prohibit their step. In that case, companies only have to show that their batteries are as safe as any other component of a car. As if I could pass them a tank over them. The crazy idea of ​​a tank Although it seems nonsense, it makes sense that manufacturers refine ideas when demonstrating the safety of electric car batteries. Keep in mind that, for example, In South Korea, an intense debate has been lived on whether or not these cars may accumulate in garages after A Mercedes Eqe will explode last year. When Byd arrived in Spain he had a challenge ahead. I needed to make themselves known and, above all, demonstrate that it was a company in which you could trust. We already know the prejudices towards the Chinese product. As a journalist, I don’t know how many times I could visualize This video in which a nail is going through an LFP battery without anything happening. It was one of the classic images. The other was the pressure tests. When too much pressure is applied to a battery (electric car or any other device) runs the risk of experimenting A thermal leak. Heat grows inside, chemistry is released and the pressure increases to cause an explosion with the consequent fire. To avoid this, the housings are designed to release the accumulated pressure inside, with the aim that if we have an accident, the pressure exerted on the battery does not cause an explosion. And the company can already tell us about figures and data and everything we want. But nothing better than the visual. Click on the image to go to the original tweet That is why Geely, explain in Carnewschina He has taken his new “Aegis Gold Brick Battery” a 36 -ton tank and has passed it over. And what happened? Nothing. Nothing at all. The battery did not give any sign of damage despite receiving 1.8 times the minimum pressure required by Chinese institutions to standardize a new battery. You can see the video on this link. They point out that the tank not only He crushed the battery On one occasion. He passed over it, returned on his steps and continued to crush her repeatedly. And did the same going over individual cells. The battery package “maintained its structural integrity without bulges, leaks, fires or explosions,” they emphasize. To overcome the test, the aegis Gold Brick Battery has been designed with a double wet coating that facilitates the dispersion of heat and thermal leaks since it is especially heat resistant to heat generated by aluminum oxide. It also has liquid-electrical separation of the materials. Photo | Geely In Xataka | Samsung has just revolutionized batteries for electric cars. In autonomy, in load time and in useful life

The Artikutza reservoir in Navarra has remained empty despite the rains. His destiny is another: the demolition

by

The rains of recent months have caused many of the reservoirs of the Peninsula to go from practically dry due to drought to recover flows more typical of normality. That is not the case of the Artikutza reservoir, a Navarrese reservoir located near the border between the Foral Community and Gipuzkoa. The reason is that the Artikutza reservoir is a dead reservoir, and its prey, as we know it, has the days counted. Green light to demolition (partial). The San Sebastián City Council It is prepared For the partial demolition of the Artikutza dam as reported by local authorities. The infrastructure, in disuse for more than 20 years will be measured so that the so -called Enobieta regatta, whose flow retained the prey leads to the Añarbe River without having to cross the infrastructure pipes. The works are expected to begin in 2026. Wasn’t we in Navarra? According to He tells Iñigo GarcíaCouncilor for the Environment of the Donostiarra Consistory, to Efeverdethe history of the Artikutza reservoir begins in 1919, when the City Council bought some land next to the population of Artikutza, in the north of Navarra in order to build a reservoir that supplied water to the coastal municipality. The dam never was fully filled: in 1948, geological problems were detected that limited the filling capacity of the reservoir to approximately half of the planned volume. In spite of this, the reservoir was the main source of water supply of the Guipuzcoan capital between 1960 and 1976, when downstream entered into the service of the Añarbe reservoir, of a much higher volume to face the population growth of the city. A spoiled dam. In 1992 the reservoir stopped supplying water to the municipality of Donostia, but its final decline would begin ten years later, in 2002. This year, a failure in the electrical maneuver Reservoir coffin. Reservoir that would end emptying more than a decade laterbetween 2017 and 2019. A duct in the lower part of the dam allows the small regato to flow with hardly any restrictions, but the new project seeks to further facilitate the transit of the river and avoid risks derived from the accumulation of sediments. A partial demolition. We indicated at the beginning that the demolition of the dam would be partial and not total. The Donostiarra Consistory considered three demolition options: the total demolition, the partial and the possibility of maintaining the current channeling to maintain an open passage. Finally, the decision was favorable to the partial demolition, which implies the opening of the dam through a vertical cleft of seven meters wide below one of the old reliefs of the dam. This would allow recovering the natural flow of the river avoiding at the same time A cumbersome work in a protected natural environment and complex access. Protect fauna. Now the question fits, and all this for what? The possibility of leaving things as they were was on the table. However, it was considered that the opening of the dam was an ideal way of guaranteeing biological connectivity without the risk that the accumulation of sediments will hinder the passage of water and animals. There are several species whose conservation has been influenced when explaining the ecological impact of the project. The first is The Iberian Desman (Pyrenaicus Galemys)an animal that also receives the nickname of the “Spanish ornitorrinco”. This animal is one of the most threatened mammal species of our environment and has a small population in this hydrographic basin. The authorities also highlight the existence of “Bat populations of much biological interest” that inhabit the interior of the dam.

We have genetically edited a spider to produce a fluorescent red cloth. And the implications are promising

by

Mutant spiders. It could be the premise of a film that mixes science fiction and terror, or someone’s nightmare with Arachnophobia. However, the first mutant spiders created by the human being respond to something much more innocent. But maybe even more interesting. Mutant spiders. A group of researchers He has genetically edited A group of spiders. The most curious of the results obtained by this team is probably a group of spiders that, after the edition, are capable of weaving a red spider web fluorescent spider. It is about First experiment of genetic edition in spiders of which we have knowledge. For this, the team resorted to specimens of the American domestic spider (PARASTIDA TEPIDARIORUM), A species that, like many others, uses its spider web not only for hunting but also to protect its eggs. A fascinating material. Spider silk is one of the most interesting materials in the animal world. Spiders are capable of segregating different types of fabric and among them, structural silks are among the most remarkable for their very tangled resistance that binds to its elasticity, lightness and the fact that it is a biodegradable material, explains the team responsible for the study. CRISPR-CAS9. In its experiment, the team turned to the “scissors” of genetic edition CRISPR-CAS9. They began the process focusing on a gene linked to the development of the eyes with the aim of obtaining a first easy result to identify. The team injected his tool of genetic edition in a female in order to eliminate the gene chosen in their reproductive cells and thus be able to detect changes in their litter. The Resutlanted: Spiders who did not develop their eyes. From the eyes to the silk. The first success led to repeat the test, but this time focusing on the genes responsible for coding some of the proteins present in the structural silk of the spiders. In doing so, spiders wove spider silk filaments of fluorescent red spider. The details of the experiment were published In an article In the magazine ANGEWANDTE CHEMIE. A first step. To be able to edit the genes responsible for the production of a material as interesting as the structural filaments of spider fabrics opens new doors when it comes to knowing this material and its biochemical origins. Of course, we can also pave the way for being able to synthesize it efficiently or even in the development of materials with similar properties. “We have demonstrated, for the first time in the world, that (the tool) CRISPR-CAS9 can be used” to incorporate a desired sequence in spider silk proteins, thus allowing the functionalization of these silk fibers, ” stood out in a press release Thomas Scheibel, co -author of the study. “The ability to apply CRISPR genetic edition to spider silk is very promising for material science; for example, it can be used to increase the already high spider silk breakage.” In Xataka | ‘The Last of Us’ is already happening in the animal world and the last species in suffering are the “spiders of the caverns” Image | Patrick Edwin Moran / University of Bayreuth

Four AI companies control how Half Mundo reasons. It is the greatest concentration of intellectual power in history

by

While the public focus is concentrated in the possibility that the AI ​​will take our job ahead (Business Insider 21% of its template has just announced citing it as a cause, the CEO of Axios has published A text by the chungosAnthropic’s CEO has shouted “that comes the wolf” to justify that only they can save us), In the background something less visible is happening: We are giving our intellectual autonomy in favor of efficiency and comfort. It is not just that four companies –Openai, Google, Anthropic, Meta – are building the infrastructure with which millions of people resolve doubts and make decisions. They not only manage data: they also protect the way we link ideas. The Great Chinese of AI They are out of this equation for a simple reason: their still domestic approach without the international vocation of the Americans. Google (the search engine) was and is influential, but with it we have had to spin our own speech: Cotejar Fuentes, Weighing biases, assume contradictions. The generative AI instead serves a round response that It sounds coherent even when hallucin And that’s why he demands less surveillance. The result is that we are replacing the “internal process” with an external verdict covered with a technological aura that deter the replica. Whatever you say, Chatty. Delegate is too tempting. Save time and headaches. The problem is that we do not subcontract logistics, but criteria. We ask Chatgpt A professional strategy. TO Claude A curriculum. TO Gemini today’s interpretations. In doing so we accept without discussing the biases and empty of a trained model about texts that we will never see. It is an invisible assignment and, therefore, difficult to question. Never before so few hands had defined what questions can be asked and what answers sound reasonable. History has known infrastructure monopolies – electrity, internet, railways – but never one about reasoning patterns. Now another qualitatively appears: It operates on the symbolic plane, where narrative frames are defined through which we understand the world. Very subtle and very decisive. What previously implied a deliberation – read, contrast, imagine scenarios, weigh nuances – today becomes an instantaneous response, of definitive appearance. What to think about euthanasia? How to react to infidelity? What economic model is more fair? We no longer look for elements to think: we look for the correct answer The faster and more comfortable. And we accept as valid the one that sounds best, even if it ignores what does not fit in your narrative. Its effects will not be immediate, but predictable: a slow loss of variety in thought, of ideas out of the ordinary. Platforms have progressive consequences. Tiktok and Spotify, for example, They have made the songs last less and the chorus arrive before. What consequences will the LLMS within fifteen years? If we all consult models that converge towards average responses, intellectual eccentricity – culture rate for innovation – It will be increasingly weird. There is hardly a brake for AI, but perhaps at some point we have to decide how much reasoning we are willing to deliver before staying without it.
