The United States created modern globalization. Now he has become his main devastating

by

The world never changes from one day to another, but Sometimes there are inflection points that we only recognize in retrospective. The fall of the wall in 1989, the collapse of Bretton Woods in 1971 or the crisis of Lehman Brothers in 2008 marked the end of one era and the beginning of another. Today we are facing a moment, very possibly, similar. The phrase of British politician Darren Jones, “globalization as we have known during the last decades has come to an end,” collected by Newsweekmay sound reactionary exaggeration to Trump’s tariffs, but it is not. We are in something that goes beyond a commercial war. It is the decline of an economic order that has supported world prosperity for three decades. Tara Zahra explains it in The New York Times: It is a moment that reminds the collapse of the first era of globalization after 1913, when the value of global exports went from 14% to 6% of the world economy. The United States was the main architect of this system, but has become his great devastating. The country that was leveled in the virtues of free trade to grow now applies The same base tariff both to its democratic allies and to regimes and the Taliban. In fact we have higher tariffs in the European Union than in North Korea. It is not only the capricious policy of a single president, but the final demonstration of a long process. As Zahra documented, the notice arrived in 1999 with those anti -globalization protests in Seattle that had their replica in various parts of the world. In our case it was In Barcelona. Tens of thousands of protesters against the WTO. That intensified with the 2008 crisis and the pandemic completed this cycle: our supply chains were more fragile than we thought. The world was already fragmenting before Trump’s return to the White House. The alarming thing is what happens on the other side of the Pacific. China is not regretting for anything or waiting for better times with stoic resignationbut is actively building its own independent economic sphere. The case of Huawei It is exemplary: it does not build bridges, cava trenches. Its strategy is no longer going to compete, but to create its own parallel and self -sufficient ecosystem. Beijing in the meantime has been preparing his countermeasures to Trump’s tariffs, from the climbs to his own to the prohibition of American films. They are not only defensive responses, but the steps of a long -term strategy to reduce its exposure and dependence on the West. Beijing creates its technological ecosystems, but also financial and commercial. Within our possibilities, In the EU we are also looking for the box of the strips. Begin An era of independent islands. There are changes that can be reversed when Trump leaves the position and the following arrives, but others will be permanent. Once broken, trust is not easily restored. What happened to Huawei and others in 2019 was A lesson engraved on fire: The dependence of any market (especially the American) is a vulnerability. Praness Narayanan, from the London Public Policy Research Institute, explains it in NBC: “The decisions that make (companies) following this will remodel global trade.” The result will be a more fragmented global system, more redundant and, paradoxically, less efficient that the one that has emerged from globalization. Aurélien Saussay, from the London School of Economics, anticipates That the price to be paid for this “dysglobization” will be transferred to consumers in the form of higher prices and lower supply variety. Many of the pieces that have built the imperfect framework that has given the greatest global prosperity in history are being undone. Just now that AI, climate change and demographic complications should demand more cooperation, no less. The pendulum again oscillate to closed borders and autarchiesto some extent. China wants to be self -sufficient, the United States seeks something similar and the EU, which was to other things, Start wondering what you have left to protect. Now it remains to know what will happen in the future: not if globalization can be saved – it seems very difficult to undo certain steps – but what we will build on their remains.

So many second -hand cars from Tesla have never been sold. It is the nth proof of the crisis created by Elon Musk

by

American policies have taken a 180º turn as far as electric mobility and automobile industry are concerned. In recent years we had become accustomed to fiscal incentives for the purchase of electric cars and their production in North America. In just a few months, Donald Trump has confirmed what we already suspected: is determined to end it. First eliminating tax incentives To buy an electric car, a project that is still underway and that would eliminate the subsidy of 7,500 euros for the purchase of cars of this type. Second with the imposition of 25% tariffs to everything that between its borders. Joe Biden’s government made the Inflation reduction lawin which they contemplated Fiscal aid to those who produce in the country but also to those who centralize their production in North America, including Mexico and Canada with whom the United States has a special commercial treaty. However, the tariffs approved by the new Government of Donald Trump will tax with 25% all cars or pieces for the manufacture of them that enter through their borders, including these last two countries. Curiously, Tesla benefits of both measures. It is not that he draws a direct benefit on them, the problem for the competition is that it affects them more than the company of Elon Musk. Tesla leads in the sale of electric cars in the United States with solvency since they have the best autonomy/price ratio and A supercargators’ own network. Two key aspects in a country with a network of poor loaders. Secondly because they are the only ones that manufacture in the United States all the electric cars that sell in the country. Yeah, Elon Musk has gone to x to throw balls out And say that Tesla will also be affected by tariffs but, of course, It will be to a lesser extent that those who manufacture outside the borders of the United States. And, despite everything, Tesla have to demonstrate that he can keep holding rhythm. Good for the political positions of Donald Trump or because the company begins to find its roof, more and more Tesla electric cars are more in the second -hand market. In fact, according to Reutersthey have never been so much. A second -hand market that is a reflection of much more So many Tesla had never put themselves in the second -hand market in the United States. Is what he states Reuters. The Communication Agency has used the data of Edmundsa well-known portal of second-hand cars in the country. The agency indicates that last month, Tesla represented 1.4% of the transactions that were carried out on the platform. It does not seem a figure too high if it were not because in the same month last year they barely represented 0.4%. That is, in February 2025 they were sold three times more second -hand tesla That a year ago. From the Purchase Portal, they point out that the data is a reflection of how “loyalty to the brand is being reduced (…) Elon Musk’s public participation in the government, concerns about Tesla depreciation and saturation in metropolitan areas are making some owners Insights of Edmunds. The depreciation of cars that have been put on the market, for the moment, has not been felt significantly, collect in Motorpasion. However, they are echoing the notices of the portal itself that warn that if the trend is maintained if they should be noticed very soon. The company is immersed in a Huge image crisis Derived from Elon Musk’s policies, their public appearances and their comments on social networks. Since the new president of the United States took the direction of the country we have seen the Tesla CEO Make Nazi greeting, show off the sound of deportation chains either say goodbye to thousands of people of the American public administration. All this has led to a Boicot to the companywith manifestations, attacks on concessionaires and even a bit more imaginative proposals (such as projecting images In the Tesla factory in Berlin either In Cybertruck themselves) that have been more numerous in France, Germany and, of course, the United States. That image crisis may be deriving in a Substantial Sales Fall of new cars and in the appearance of cars in second -hand portals, although more time is needed To verify to what extent is a trend or it is an internal and structural issue of the company, with a delay in the enrollments due to the arrival of the renewed Tesla Model and. What is palpable is that the disenchantment with the brand has been accentuated over time and, especially, during the last weeks. We have owners who have “disguised” their teslas as vehicles from other companies and, above all, we have a good handful of influencers publishing the sale of their electric cars. Already in September 2024, Automotive News He collected the tendency that Tesla’s owners began to put their cars embarrassed by Elon Musk’s statements during the US elections campaign. These decisions have been extended until they reach personalities with a large public speaker in the United States. From singer Sheryl Crow to actors like Jason Bateman. As we say, to finish understanding these manifestations and that media speaker is generating a real impact On Tesla’s sales we should see how the months continue to advance and check what real impact the arrival of Tesla Model Y. What is certain is that the company has a real problem to sell other vehicles, such as Cybertruck. And also that the number of vehicles in the second -hand market seems to be growing very substantially. Photo | Robbie and Maxim In Xataka | Tesla sold less cars in 2024 than in 2023.

If the question is where and when to see the solar eclipse of March 29, NASA has created a map to answer you

by

This Saturday 29 we will have a new opportunity to see an eclipse (partial) of sun, at least if we are in an extensive region of the northern hemisphere that covers a good part of Europe (including Spain), but also parts of North America, Africa and Asia, and even a small region of South America. The eclipse, on a map. To help visualize where and when the Eclipse de Sol can be seen, the US space agency, NASA, has published a map in which the region is represented from which this partial eclipse will be visible. The map also includes time information with which to guide us. The yellow lines of the map They allow us to get an idea to what extent the sun covered by the moon will be depending on the place where we find ourselves. The area where more darkness is reached is located on Canada and Greenland, where more than 80% of the solar disc will be covered. The point of greatest concealment will see how it disappears about 93.1% of the disc area. The green lines, meanwhile, indicate the moment in which this maximum solar concealment occurs in each area. The hours are indicated in coordinated universal time (UTC), which during winter coincides with the time of the Canary Islands archipelago. One more hour in the Peninsula and in the Balearic Islands. The dawn line. The orange lines delimit the area where the eclipse will occur during dawn. The points that travel the orange line located further west are the places where the eclipse ends during dawn, while the orange line further to the east shows us where the eclipse begins with dawn. The blue line located between both joins the points where the eclipse will reach its peak during dawn. The map created by NASA to illustrate the eclipse route. NASA Scientific Visualization Studio. Where will you see better. Yes We focus on Spainthe darkness will be greater the more we find ourselves. Thus, for example in A Coruña, 31.6% concealment will be reached, while in Mahón the concealment will be 8.85%. In Madrid and Seville the concealment will be similar, about 20%. Less than in cities such as Gijón or Ponferrada (about 27%), but more than others such as Barcelona or Murcia (around 13.5%). Animated visualization of the areas that will be hidden during the partial eclipse of the sun of March 29. POT. When will it be seen. The eclipse will arrive in the morning and the first autonomous community in being able to see it It will be that of the Canary Islands. Specifically, it will be in the surroundings of the Punta de los Reyes, in El Hierro, where the eclipse will begin at about 9:11, local time. The shadow will move in a northwest direction so that the last point of the Peninsula in being able to see the eclipse will be Euskadi, more specifically in Hondarribia, where the sun will look again fully at 12:41 a.m. On the map We can see how in most of the Peninsula the maximum of the eclipse will occur between 10:30 UTC (11:30, local time or CET), and 11:00 UTC (12:00 CET). Caution. Eclipses are astronomical events easy to seebut dangerous for our view if we do not take precautions. It is essential to use protection if we want to see the eclipse but it is not enough with simple sunglasses, we need specialized glasses to be able to see this type of event without putting the health of our eyes at risk. We also have ways of seeing the eclipse indirectly and safely.

More than a decade ago, Seville created a system to defend against Guadalquivir waiting for not having to use it. Last night he had to activate it

by

Anyone who was yesterday at the entrance to the Pava Charco, could see how the city’s firefighters They moved the huge gates of defense that shield the city of Seville of the floods of the Guadalquivir River. And it is likely not to know, but I was attending a historical moment: it is the first time since it was built that these steel plates (more than four of meters high and five tons of weight) have to close. Phase 1. Yesterday afternoon, the Hispanic City Council activated the emergency plan in phase 1 and brought together all emergency services (including Local Police, Civil Protection, National Police and 112) to coordinate the necessary measures. 30 people were evicted from a “chabolist settlement” that was in flood zone, control points were installed and It was decided to close The connection that connects La Vega de Triana with the city. That’s where the doors that have just closed are. He has also put the neighbors of Tablada, Valdezorras and El Gordillo on alert. But hadn’t it stopped raining? Yes, weather forecasts They do not show abundant rains In the area and in fact (although the red alert is maintained) the river flow has already begun to decrease in Córdoba. However, when we talk about Seville, the river is just one of the things to take into account. The tide. Although it is often difficult to imagine, the truth is that when the Guadalquivir arrives in Alcalá del Río (that is, 15 kilometers before reaching the municipality of the city of Seville) It is already at sea level. That makes that point more or less, the entire riverbed is subjected to the influence of the tides. And that is what worries the authorities: if the river flood coincides with the pleamar, the chances that the Guadalquivir will overflow begin to be huge. How historical is this really? Indeed, to say that the doors have closed for the first time is not saying too much: they settled in 2012 and the last time the city was on the edge of the debacle It was in 1996. However, the challenge is more than considerable. Because, like Díaz del Olmo explained years agoProfessor of Geography of the University of Seville, the reduction of the alluvial plain of the Guadalquivir (which has gone from 4 kilometers to 500 meters) adds risks to the situation. “It is worth that with the swamps that retain the water, so much alluvial plain is needed, but the current one is not much less sufficient,” he said. And not only for the plain itself, but because “If the river is wide and with meanders, the energy that the water carries is blurred; but if it is narrow and straight, the water acquires a great speed … like the flow of the river rises of the 4,000 cubic meters per second … we have a problem for which they do not serve neither the storm tanks or anything.” A monster called Guadalquivir. Luckily, we are not yet in that situation. However, this is a warning for navigators: taught by tons of concrete, rivers are sleeping monsters, but monsters after all. Just yesterday we talked about The great paradox of our time: Have to prepare for long periods of drought while we have to have infrastructure to contain torrential rains. Today we see that it is not something punctual, it is the true “new normality.” Image | Toni Pomar | ECMWF In Xataka | With the reservoirs to be overflowed with the rains of March, there is a reason for hope on the horizon: the light of the light

The radar satellite at a higher height ever created

by

At 36,000 km altitude, in the geostationary orbit, China operates the “Ludi Tance 4-01” satellite. Released in August 2023is the first synthetic opening radar deployed at this point, which gives China a unique permanent observation capacity on a third of the earth’s surface. Freshly declassified. Chinese scientists have Recently revealed The design and capabilities of the Ludi satellite, which had been kept secret until now. Officially designed for weather observation, earthquake monitoring and natural disasters prevention, their details have put on alert to rival countries such as the United States. The United States Space Force rejects the Chinese narrative. Instead of a satellite for civil use, he believes that it is designed for high resolution recognition in the Asia-Pacific region: a powerful spy satellite that allows both civil applications and the collection of military intelligence. The reason for its height. Ludi is, Like the Spanish satellite Paza synthetic opening radar (SAR). But unlike peace, it is the first and unique Sar that operates in geostationary orbit. Located 36,000 km altitude, the Chinese satellite is synchronized with the terrestrial rotation to observe the same region continuously. And not optical, so it can cross the clouds and follow night objects. Ludi reaches a resolution of approximately 20 meters. While it is a lower resolution than the sub -metric of some spy satellites of the low orbit, from the geostationary orbit, Ludi can monitor around a third of the earth’s surface, specifically in the Asia-Pacific region. The technical details. The satellite was launched with its antenna initially folded. To achieve a useful resolution at so much distance, LUDI integrates numerous phase matrix emitters, which can be coordinated in unison. This “beam synthesis” technology allows multiple microwave beams to be combined in space to act as a single very powerful radar beam, which makes it possible to obtain high quality images. Only China. The launch of the Ludi in August 2023 marked the beginning of a new class of Earth’s observation platform. American scientists had pursued the idea of ​​radar surveillance from the geostationary orbit since the Cold War, but technical obstacles maintained all those plans on paper. China has succeeded. And Ludi is alone one of the Chinese satellites yaogan that operate in geostationary orbit. Image | Cast In Xataka | For the first time we have seen a photo taken by the US ultrasecreto space plane.

Kukulcán’s show that the Maya created 900 years ago

by

Every year, around March 21, an old Mayan God returns to Earth. Specifically, Chichén Itzá. This complex of Mayan ruins It is one of the main pre -Hispanic archaeological sites in Yucatán and, among all constructions, ‘El Castillo’ takes the palm. It takes us fascinating Since the mid -nineteenth centurybut in addition to knowing him by that name, we can also refer to him as the temple of Kukulcán. And, like every Spring equinox For centuries, that divine snake has been about to come alive to descend through the staircase and inaugurate the spring station. Kukulcán. Although the mythological imaginary of the Maya was incorporated late, Kukulcán soon won a fundamental position in this pre -Hispanic culture. That is, if it were a minor deity, it would not have something as monumental as the pyramid that the Maya built in their honor in the twelfth century DC Thus, Kukulcán is the supreme god of the universe that not only represents wisdom, but also fertility and life. Photo by Daniel Schwen The castle is so fascinating that it is still reason for study todaybut centuries after its construction, there are two moments every year in which their stairs are a footpasted again by a God. The descent of the feathered snake. The structure has a very precise shape and orientation that respond to the advanced mathematical and architectural knowledge of the Maya. Kukulcán is also the God who represents fertility and life, something that can be associated with crops, and the visit of this God is a blessing for crops. The sowing of the Milpaspecifically. Thus, the Maya built their temple very precisely so that each spring equinox, which occurs between March 21 every year, the representation of the snake again descended through the staircase of the temple. This 2025 se esteem which will occur between March 20 and 23. A few hours before sunset, the large blocks of one of the sides project triangular shadows on the side of the staircase, forming a series of triangles that connect with the huge stone head of the snake, Kukulcán, located at the base of the pyramid. Beyond the show. Apart from those huge mathematical, astronomical and architectural knowledge of the Mayan civilization, the descent of the feathered snake marks the beginning of spring and, therefore, the renewal of life. He also symbolized the union between heaven, earth and underworld and supposed a blessing for crops. It lasts little, just about ten minutes and can also be seen during the autumn equinox, around September 22. In the end, it is the two periods that mark the beginning of the two agricultural cycles and it is Kukulcán who gives his blessing so that the crops are abundant. A party. Apart from symbolism and tradition, Kukulcán’s descent by the staircase of Chichén Itzá is a Tourist stop mandatory if we are in the region. This Archaeological site It is, by far, The most tourist point of the Yucatan Peninsula (and from Mexico), with tens of thousands of visitors every year, and the show of the feathered snake is another opportunity to take advantage of pre -Hispanic construction. Now, greenhouses and crop rotation allow us not to depend so much on Kukulcán’s good humor, but we have turned their two annual arrivals into a party that brings together thousands of visitors. It is a show not only because it is the construction of the pyramid, but because traditional Mayan shows and rituals are carried out with music and dance. Chance? That the Maya had great knowledge in mathematics and astronomy is somewhat indisputable, but there are positions that question that all this of Kukulcán’s descent was the result of the conscious design of the Maya. The reason that is used in the re-evaluation Of this thought is that yes, the phenomenon and the play of lights is important during the equinoxes, but the same effect can be seen clearly for several weeks. Rather, instead of marking with tremendous precision a few days of the year, the Maya would have darling Mark an agrarian cycle from mid -February to October. As much as it may be, and it had the meaning that we give now, the architectural value of the site and the architectural intention of representing that descent of the feathered snake is still unappealable. Kukulcán’s head | Photo by Frank Kovalchek But … it’s not unique. Now, although that of Chichén Itzá Castle is the most famous point in which to visualize these projections, it is not the only Mayan construction in which a similar phenomenon occurs. In it Temple of the Seven Dollsor temple of the sun, in both equinoxes we can see a solar rays show through the openings of the structure. Also in the Mayapán pyramidbut the big difference between the pyramid of this city and that of Chichen Itzá is that there is no huge snake head connecting with the earth and that, in addition, it is not as well preserved as ‘the castle.’ Centuries after his arrival, and although now he has less work, surely Kukulcán feels honored because his pyramid not only stands up, but for having turned his figure into the protagonist of a party. And that is why he continues to descend for one of the main constructions of the Mayan culture. In Xataka | The fines imposed by Mexico for getting on the pyramids of Teotihuacán or Chichén Itzá

A company has created a humanoid robot of 38,000 euros and can already be reserved

by

Imagine it: A humanoid robot serves you a glass in your favorite bar, another directs traffic with millimeter precision and, in the bank or in the hospital, a human aspect welcomes you. Some even find a company in these automatons designed to look empathic. In a world in constant progress, the future seems clear: humanoid robots will be everywhere. How much is missing for this vision to come true? We do not know with certainty. Nor what unknown challenges will arise along the way. What is a fact is that the career to develop humanoids is more intense than ever. And in that global competition, With companies from the United States and China in frontthe last movement of China Ubtech Robotics does not go unnoticed. A real -scale humanoid. The Beijing and Ubtech Robotics Humanoid Robots Innovation Center have made known Tien Kung Xingzhe, a humanoid robot with dimensions similar to those of an adult. As we can see in the images, its design is quite futuristic, with a metal torso in gray and black tones, articulated arms and a head without facial features. But beyond its aesthetics, it stands out for several advantages: Advanced biomimetism. Its structure and movements are designed to imitate with great precision those of a human being, allowing him to interact more naturally with his environment. Maximum stability. It can move fluently even in complicated land such as mountains, stairs, sand or snow, without losing balance or compromising your performance. Disated to resist impacts. The key parts of the robot are manufactured with titanium alloy, which should reduce the total weight without compromising its structure. High performance and efficiency. Designed to operate with precision and stability in research environments, guaranteeing reliable and consistent results. Gran expansion capacity. It is compatible with additional modules such as depth cameras, lidar, strength sensors, collaborative arms of seven degrees of freedom and robotic hands of five fingers, which allows you to adapt to different needs. The Tien Kung Xingzhe has a bionic torso configuration and an anthropomorphic movement control system, which allows it to move with surprising fluidity. It has 20 degrees of freedom (DOF), that is, 20 articulation points that allow it to imitate with greater realism human movements. The more degrees of freedom has a robot, the more precise and natural its displacement will be. A robot for research. Despite the advances in robotics, the humanoids we have seen in science fiction are still far from reaching our homes. Therefore, Tien Kung Xingzhe is designed for the world of research. Its price, 299,000 yuan (about 38,000 euros), places it in an accessible category for development centers and universities. In line with its purpose, it has an open structure that allows access to its motor, sensors and movement control interfaces. It also includes documentation and code examples to facilitate customization and development of new applications. Do not wait too long. For those who closely follow the evolution of humanoid robotics, the Tien Kung Xingzhe is now available for early orders in China and deliveries are planned to begin in the second quarter of this year. If the deadlines are fulfilled, an Asian company could have advanced to several of the proposals that are being developed in the United States. It is true that we talk about different categories: while Kung Xingzhe is designed for research, other companies, such as Tesla with their Optimus robot, seek to produce mass humanoids for industrial tasks. However, in terms of early availability and adoption, China seems to be taking more than interesting steps.

The Basque system will exceed The recent German IBM installationwhich operates with Eagle processors of 127 cubits. Why is it important. Quantum computing promises to transform the science of materials, physics and medicine solving unabordable problems for conventional systems. He System Two It already reaches the “quantum advantage”, executing impossible operations for traditional supercomputers. Its modular design will allow expanding capabilities while the mitigation of errors progresses, the greatest challenge of this technology. In figures. The Basque Government will invest 50.8 million euros in the project, part of a regional strategy of 120 million. The performance of the new processor is spectacular: 16 times more precise and 25 times faster than its predecessors. With 156 cubits, the Heron processor inaugurates what IBM calls “it was of quantum utility.” The context. The announcement coincides with the recent presentation of the first quantum computer with 100% European technology in the Barcelona Supercomputing Centercreating an axis of quantum excellence in Spain. Barcelona bets on European technological autonomy with a system developed by Qilimanjaro and GMV. San Sebastián is associated with IBM to access the most advanced technology in the market. Both strategies complement and position Spain in the European avant -garde. And now what? The IBM-Euskadi center will be available for scientists, educators and companies through its open source software Qiskit. Remote access will allow researchers from all over the world to take advantage of their abilities. According to Lehendakari Pradalesthis infrastructure “will be key to the digital transformation and economic development of the Basque Country”, facilitating international collaborations. Deepen. The quantum race accelerates. IBM plans for 2029 Your “Starling” systemwith complete errors correction, multiplying the possibilities of practical application.

Some scientists have created a camera that detects faces at 100 km

by

China continues to progress without technology brakes. Although many innovations focus on the civil sphere, others reinforce their military and intelligence power. Proof of this is an experimental system that promises to analyze objects kilometers away. We are talking about a technology that could promote an important leap in its espionage capabilities. The information comes of South China Morning Postwhich details how a team from the Aerospace Information Research Institute of the Chinese Academy of Sciences has achieved successful observations with an innovative laser system. This operates in optical wavelengths and helps obtain huge distance images, if certain conditions are met. A new observation system As we can see in the visual representation, the researchers displayed the system on a shore of the Qinghai lake, an immense Alpine lake in the remote northwest of China. On the other side, to 101.8 km awayThey installed a set of reflective rhymes. The impressive thing is that, despite the huge distance, the system managed to distinguish details of just 1.7 mm wide. The laser makes the difference. They say that it reaches an accuracy of 15.6 mm when measuring distances, which theoretically leaves the spy and telescope chambers with lenses, surpassing them by a factor of 100. Now, the observations must be made with optimal climatic conditions, stable wind, low cloudiness and, in observations of the orbit, clear skies. Although the tests have been performed on land, the Hongkonés newspaper points out that this technology could be used for espionage from space. Its unprecedented capacity to capture details would allow Identify faces from orbit Or, in reverse, analyze satellites from adversary countries with great precision from the surface of our planet. If the question is how they have achieved it, the answer is in a combination of innovations. To begin with, the researchers divided the laser beam into a 4×4 microlent matrix, which allowed to expand the optical opening of the 7.2 mm system (0.68 inches) to 68.8 mm (2.71 inches). With this approach, they managed to overcome the usual limitation between the size of the opening and the field of vision. In addition, they incorporated a specialized laser module capable of emitting signals with frequencies higher than 10 gigahecks. Thanks to this, the system reached an extremely fine range resolution, allowing distance measurements with great precision. At the same time, a narrow color spectrum was maintained to improve the resolution of the azimuththus optimizing detail detection.

Some researchers have created a pill that mimics the effects of the lack of oxygen. They have a good reason

by

Height evil is one of the problems that professional mountaineers and occasional visitors who decide to ascend to certain altitudes must face. This disorder is related to the lack of oxygen, hypoxia, which occurs in these environments, but now a pharmaceutical company wants to turn it around. Turn that “evil” into a “good.” Hypoxystat. Transform the mountain air, or rather, the absence of air of the mountain, into a pill It is the proposal of the Gladstone Institute and Maze Therapeutics laboratories. The new drug has received the name Hypoxystat and its goal is to fight against metabolic disorders such as Leigh Syndrome. Mountain air. It might seem crazy idea, but reducing the amount of oxygen that enters our body can make sense in certain senses beyond high performance sport. Living in a mountainous area can benefit people with Leight syndrome, a mitochondrial disease that affects childhood. This disorder occurs when the mitochondria, the organelle in charge of feeding the rest of the cell is not able to consume all the oxygen it receives. This leads to a dangerous accumulation of oxygen that ends with cells and tissues and, ultimately, with the patient’s life. “It is not practical for each patient with this disease to move to the mountains,” Explain in a press release Isha Jain, who has led the recent study of the drug. “But this drug could be a controlled and safe way to apply the same benefits to patients.” 2016. Almost a decade ago, a team, in which Jain herself participated, discovered that mice with this syndrome responded well when they were exposed to air with a lower amount of oxygen, the equivalent of that which can be found at heights of 4,500 meters (a upper altitude in almost a kilometer to the Teide peak). The lack of oxygen caused it to stop accumulating in the cells. The new compound could achieve a similar effect in a different way: focusing on hemoglobin, the molecule that transports oxygen in our blood. The new compound causes oxygen to be linked more easily to hemoglobin which may sound contraintuitive, they explain. However, this fact also makes it difficult for the molecule to deliver oxygen to the cells of our body. Concept test. The new drug has been developed Maze Therapeutics to fight anemia. The Gladstone Institute team, from the University of California San Francisco, found the substance when looking for a compound capable of reinforcing the bond between hemoglobin and oxygen. As a treatment, Hypoxystat is still in early development, but has already begun to succeed in mice. The details of these tests have been published recently in an article in the magazine Cell.
