If this week you do not find who fixes your phone, maybe he is competing in the mobile repair World Cup

by

If something can be gamified, we are going to gamify it. It is the best way to turn a daily task into something fun. Not surprisingly, there is a World Cup to collect garbage in Japan -How no-, but it is also something that allows demonstrating the skills in a program that many use, but not so many dominate: The World Cup. Cut by the same pattern is the CGC World Cupa competition that has become the World Cup to repair mobiles. It is an event in which knowledge is shared, workshops are held and in which the main course is a fight repairing a smartphone under very strict rules. CGC World Cup. During the last months, in countries such as Mexico, Colombia, Egypt or Indonesia, the qualifying phases of this competition have been held. The best talents of each region came with the hope of taking one of the squares in the final that will be held in the Chinese city of Guangzhou Los next September 17 and 18and it will be then when they have to expose their skills in front of the public and a professional jury. 20 minutes. That is the time that participants have in the tests. The competition seeks excellence both in the precision of labor and in the most difficult in these conditions: to fulfill the clock. The evidence is nothing unknown to competitors: Screen reconditioningwhich includes the replacement of damaged glass. CPU microsoration, such as the replacement of welding spheres. Repair of other terminal components, such as Wi-Fi modules or more common elements in repair workshops. In each job there is a counter and a red button that the participant clicks when it is over. At that time, the jury comes to verify the correct performance in the evidence. There are evidence from two hours 40 minutes Nothing easy. They are situations in which we seek to simulate daily work in a workshop like we can go to to repair our smartphone, but the demand is that the greatest precision is sought at work and, above all, to fulfill a time that is really adjusted (it is not the same in your workshop than in a streaming and with people judging your work at half a meter). As if that were not enough, there are factors that influence the “game.” For example, temperature. Professional attendees to the event comment They have air conditioning, yes, but precisely a temperature that they do not control can make their times vary because they may be more accustomed to higher temperatures in the workshop where they usually work and, even if they are a few degrees, it is something that can affect processes like him receptive. In addition, each professional is accustomed to their tools (some even customize them), but in the GCG World Cup they all compete with the same weapons. The mobile repair Messi. If the mobile lights, it is functional and the work has been done with maximum precision, leaving the smartphone in optimal conditions, wins. These events have also had their controversies, but in terms of experience, it is not only a competition, but a meeting point for the more top professionals of mobile repair worldwide, with panels and courses live. It is also an interesting meeting point for brand tools and distributors brands, so a synergy is created between the different legs of the sector. The truth is that these videos of people performing microsolduras attract a lot of attention, and many of those professionals that we see on YouTube are those who compete and attend these events. Among all, it stands out Wyman Lauconsidered the best ‘repair’ of smartphones in the world and what is a show see to work. In the video below you are performing microsolures between processor pins A17 PRO of the iPhone 15 Pro. It is a repair of the most advanced. It is called ‘CPU Jumper’ and consists of bridging two specific points of the integrated circuit of the CPU by means of a conductive thread, and it is something that is done when it is detected that one of the clues of the processor has been damaged by a fall, humidity or excess heat. Wyman Lau, with its G-Lon brand, is one of the top exponents of the CGC World Cup and someone who has been seen in the events. The World Cup problem of mobile repair? That, as a public that attends live, or you look at the screen on which it is broadcast or surely do not find out about anything if you look directly at competitors, since they do work at the microscopic level.

This is how scientists are working to find all who remain

by

While the axolotl becomes a global icon, a star in laboratories around the world, an exotic pet and Even a character in Minecrafthis only natural home on the planet is about to disappear. The last time an exhaustive census was made, in 2014, scientists They could only find 36 copies in the Xochimilco channelssouth of Mexico City. A decade later, the search has begun again and is a counterreloj race to save this amphibian. The question is if any. In 1998, Xochimilco’s waters They housed 6,000 of these creatures per square kilometer. By 2008 this figure had collapsed to 100. Now, the question asked by the Ecological Restoration Laboratory of the UNAM is If one is still alive in this environment. A search between networks and DNA. Each sunrise, while a magic fog rises from the canals, Basilio Rodríguez, a former fisherman in the area, throws his stroke into the water. He does not look for fish to eat, as their ancestors did, but to the axolot, an animal that he himself remembers as a delicacy: “smooth, soft, juicy, very rich.” But today, the networks go up again and again with the same disappointing capture: tents and tilapias, two invasive species that are, in part, guilty of this story. But traditional fishing is not the only strategy they are following. Great hope is deposited In an innovative technique such as environmental DNA analysis. To carry it out, scientists collect water samples to look for the genetic traces that the axolotes leaves in its path. And it is one of the opportunities they have in their front by not having found any axolotes. An amphibian with regenerative capacity. Ajolote is an extraordinary animal. He is famous for his neotany, that is, the ability to remain in a larval state throughout his life. This eternal youth, linked to their stem cells, gives it a superpower that fascinates science: Regeneration. If you lose a leg, a piece of brain or heart, you are able to regenerate it completely in a matter of hours. A fragile species that goes to the abyss. There are different factors that influence the disappearance of this species. The first of these are the invading species that have invaded their ecosystem. The tents have devoured axolote eggs, while the tilapias are eaten to the young and compete for the food. No less important is the destruction of your home, since Xochimilco’s water has been drastically deteriorated by urbanization, pesticides of agriculture and pollution. Noise and tourism is also something that can be lethal for these amphibians. Being night animals that love silence, the presence of humans in their natural habitat making floating parties makes their ‘happy’ place become an impossible place for them. Famous in the world and absent at home. While its wild population disappears, the axolotes is living an explosion of global popularity. Its regenerative capacity is key in research on aging and cancer. His adorable appearance has made him In a merchandising product: T -shirts, keychains and stuffed animals. But experts warn. Having thousands of Ajolotes in captivity, many of them albinos and modified for research, will not save the species. The key is to restore its habitat, a titanic task that would cost about 30 million euros, according to researcher Luis Zambrano. The rescue plan is already preparing. Given the impossibility of cleaning everything Xochimilco at once, the UNAM team has launched an ingenious plan B: Create Ajolot shelters. The idea is to collaborate with the Chinamperos, the local farmers who cultivate in the artificial islands. The project consists of restoring the chinampas and surrounding them with moats and filters that prevent the passage of tilapia. In these small aquatic coffers, you could introduce seats raised in captivity with a genetic as pure and similar as possible to wild ancestors. They already look for money to carry it out. To finance this new project, the UNAM launched the campaign “Adopt an Axolotl”. In this way, for about 30 euros, anyone could adopt virtually one of the 140 copies that live in the center, give it name and help finance the creation of these shelters. Something that gave them an income of four million pesos. There are many animals in dangers of extinction. In addition to the ajolotes, in Spain this is a problem that is also present, as in the case of the Canary Islands, which is considered as the community with more species in this situation. Those responsible They can be other animalsbut Also humansas in Brazil. Images | Mattias Banguese In Xataka | During World War II, Australia sent an ornitorrinco to Churchill.

It is not that Russia does not find the F-16 of Ukraine, is that kyiv has discovered the perfect hiding place for the future of wars

by

The problem of modern wars is that they have ceased to be A geographical matterand the current technological abilities, with the drones and the AI in the lead, are eroding the physical barriers that previously existed. That was clear, for example, with The Spiderweb operation of Ukraine on the Russian air bases. In fact, in the first 18 months of the war, Ukraine lost Very few planes On land in front of the Moscow number, and the last movement predicts an even lower figure. The mobility war. The Arrival of the F-16 To the Ukrainian Air Force has been accompanied by a parallel effort to create a mobile ecosystem capable of sustaining continuous operations in a scenario where each base is a potential white of aviation and Russian missiles. Solution? The Ukrainian Foundation Eat Back Alivein cooperation with the state conglomerate Office 61 and with the financial support of the UKRNAfta energy company, recently delivered a set of vehicles specifically designed to provide the F-16 of the necessary logistics flexibility. Four wheels and fighters. The acquisition It included workshop trucks for armament preparation, crane trucks for missile and pump load, pickups for personnel transport and, above all, a missions planning complex on wheels composed of A 6×6 truck and a habitable towing module, which will allow briefings, plan operations and move quickly where it is required. With this investment, encrypted in just over 1.2 million dollarsUkraine obtains not only a technical improvement (for example, reducing from a dozen to three the number of operators necessary to assemble ammunition in each plane), but also a Operational advantage in an environment where speed and dispersion are survival synonyms. The concept of distributed operations. The logic behind this innovation is simple but strategic: prevent Russia from being able to anticipate or destroy on land Western manufacturing fighters. Ukraine had already developed the custom of Alternate air bases and even use highways as impromptu tracks, an inherited practice of the Soviet design to operate in austere environments, but now amplified by the high -tech character of the F-16. This ability to Move with infrastructure Wheel support converts each road into a potential base and each mission into a concealment game. In this sense, new vehicles are not simple trucks: they represent an adaptive doctrine in which aviation abandons the notion of fixed bases and embraces total mobility as a shield against missile attacks, drones and enemy bombers. NATO and American learning. The lessons that Ukraine applies in extreme conditions are being observed carefully by the United States and its allies. It We count The other day: the doctrine of AGILE COMBAT EMPLOYMENT (ACE), which seeks to disperse combat aviation in multiple locations Temporary, is nourished directly from the Ukrainian experience. USAF generals They recognize that Ukraine has managed to avoid the mass destruction of his aviation thanks to not taking off or landing in the same place twice in a row, forcing the enemy to waste intelligence and ammunition. The counterpart of this agility is Logistics demand: Each site needs fuel, ammunition and maintenance equipment that must be compact, transportable and fast to install. The United States Marines itself has started projects To provide air-terrifying trucks on C-130s and lighter and more modular equipment that can accompany squadrons in constant movements, which marks a deep turn in the conception of the air war. Aviation future. What’s doubt, what is today Test in Ukraine It has global implications. In a eventual confrontation with China in the Pacificno power could guarantee the protection of all its air bases, and mobile dispersion will be the key to survival. The fighters will not be able to remain in the same airfield without dense anti -aircraft defense; Their operations will be measured in hours or days, with specific deployments for refueling and rearming before returning to main main bases. This will require redesign support equipment lighterto think about new sustaining architectures and maximize land and aerial mobility. Ukraine, again laboratory. In short, the incorporation of these Ten vehicles At the service of the F-16 it may seem a lower detail in the heat of the war, but embodies a deeper transformation: that of an aviation that can no longer rely on the solidity of its bases and that depends on speed, dispersion and Logistics creativity. Ukraine thus becomes Test field of a doctrine that west, and in particular the United States, contemplates as essential to survive the high intensity conflicts of the future. Thus, each workshop truck and each rolling planning module are not only metal pieces, but symbols of how war forces to reinvent the way of conceiving today’s aerial power.

We have some ways to find the ideal place

by

Although there are still a few days to reach their maximum activity, The Perseids They are here. The most popular rain of stars will be elusive again because of the moon, which will be in its luminous phases during the days when the rain of stars reaches its climax. Fortunately, that does not mean that we cannot see them. In emptied Spain. Every year, thousands of people take advantage of summer to return to the peoples that their parents and grandparents abandoned to look for life in cities, emptied Spain. This vast rural region presents an ideal opportunity for those who want to enjoy astronomy, an opportunity that many visitors have not wanted to waste that, without a specific link, choose rural Spain as a destination with the aim of escaping from light pollution. The Perseids. Perseids are perhaps the most iconic rain of stars in the northern hemisphere. Its origin It is in small pieces of ice and rock scattered throughout the comet 109p/Swift-Tuttle In its orbit. Towards the beginning of August, the orbit of our planet crosses this path, which causes some of these particles to be captured by gravity, fall and disintegrate burned in the planet’s atmosphere, shining incandescent. The flashes of this rain of stars are becoming more frequent night by night as we get closer to the dates on which the meteor rain reaches its climax, which usually happens Around August 11 and 12 (This year will be the day 12 around 22:00peninsular time). On a clear night, the Perseids can produce at this point about 140 fleeting stars every hour. The pollution problem. This year it will be difficult to see this peak since the full moon will take place only three days before, on August 9. This implies that our satellite will be an important source of light pollution, which reduces the contrast that our eyes need to see these fleeting stars. To dodge the moon, we can try to take advantage of these days in which the Perseids approach their peak, but for this we will have to dodge another source of light pollution: the artificial lights of cities and other urbanized areas. That is where the vast extension of areas with low population density, the “donut” emptied between Madrid and the urban areas of the coast comes into play. Looking for the best places. Fleeing from the city to see the Perseids seems like a good idea but, where are we? Choosing destination can be a bit more complicated than it seems, but we have some tools at hand. The first is the map of light pollution created just over a year ago by a team from the Complutense University of Madrid and the CBAS (International Research Center of Big Data For Sustainable Development Goals). This is The map further accurate of light pollution in Spain and Portugal. The map covers most of the Iberian Peninsula and the archipelagos of the Balearic Islands, the Canary Islands and Madeira (not the Azores). We can also resort Apple -shaped maps For the mobile phone, such as ‘Light Pollision Map – Dark Sky,’ that also has a page web that we can consult from our browser. The other space tourism. Many rural areas have seen a new hook in Astrotourism to attract visitors to the rural environment. In this sense, this year’s persistent can be seen as a prelude to what will come next year: The eclipse that will travel the peninsula, predictably bring thousands of people to the areas that will be covered in sunlight. Local institutions have transformed this interest into actions to promote astrotourism through promotional companies and campaigns. An example is that of the City of Benavente, which last weekend celebrated His first ‘Astro Tourism Festival’, already with the attention set in the great astronomical event next year.

Europe had killed its hopes to find oil in the continent. Poland has just changed that

by

“The oil market is misleading.” This is warned by analyst Javier Blas In a recent article for Bloombergwhere he points out that under the apparent price stability a deep transformation that has altered the seasonality of global consumption is hidden. It is no longer winter, but summer, the moment of greatest demand for crude. And in this new scenario, Poland could be facing a turning point: the finding of the largest conventional hydrocarbon deposit in its history, in the waters of the Baltic Sea. A submerged treasure. The Canadian Central European Petroleum (CEP) company, backed by Norway investment, has announced the discovery of the Wolin Este site (We1), located just six kilometers from the coast. TVN24 He has reported That the site includes 22 million tons of oil and 5,000 million cubic meters of natural gas, with a total estimate in the concession of 33 million tons of crude oil and 27,000 million cubic meters of gas. According to calculations cited by BBCthis figure would represent around 200 million barrels of oil, which makes it a strategic finding both for its volume and its location. It doesn’t change everything, but it changes a lot. Poland consumes about 700,000 barrels of crude oil per day, but its local production does not exceed 18,000. The rest matters. In that context, a discovery that can triple national production represents more than good news: it is a potential turning point. Wolin’s exploitation could multiply national production by three, according to CEP Executive Director, Rolf Skaar, In statements collected by TVN24. In addition, the crude found has an API index of 33.4, which classifies it as light, that is, easier and more economical to refine. This finding comes when Poland has already taken Russia’s energy distance after the invasion of Ukraine: it has connected to Norwegian gas through Baltic Pipe, has reinforced its import capacity of LNG since świnoujście and has diversified its access to crude oil through Naftaport, in Gdansk. But still depending, to a large extent, abroad. Wolin can start changing that. From the finding to extraction. The concession of Wolin, of 593 km², was perforated by the specialized platform Noble Resolve, reaching a vertical depth of 2,715 meters. The We1 well was left in future conditions and geological analysis confirmed a 62 -meter hydrocarbon column in the main dolomite formation (CA₂), As detailed Gospodarka Morska. CEP has already invested about 200 million Zlotys in seismic studies and drilling, and now looks for Polish and international partners to undertake the exploitation phase. Conversations with companies such as PGNIG (now integrated into Orlen) have been restarted after the fusion of state energy. International Resonance. Wolin’s discovery occurs while the international crude oil market navigates uncertain waters. According to ReutersBrent’s futures closed Monday under 70 dollars. The reason: the new sanctions of the European Union against Russia, which now prohibit the importation of refined products in third countries with Russian crude, such as India. Although analysts believe that the supply will find new paths, concerns arise about the impact on the diesel market, more difficult to replace. That tension adds an important nuance: the new deposits in European soil are not only an energy advantage, but also a geostrategic asset. And now what? The new site will not solve the Polish energy dependence on its own, but it could mark a turning point. As the energy expert points out Wojciech Jakóbik in BBC, the finding “will strengthen energy security, provided that estimates are confirmed in practice and develop the necessary infrastructure.” Today, it is not clear if a new pipeline will be built or existing infrastructure will be used. Meanwhile, CEP holds conversations with multiple actors and, as Jakóbik recalls, the project requires companies with “greater risk tolerance and investment capacity”. An energy window in convulsive times. The discovery in the Baltic Sea comes just when the global market enters its moment of maximum seasonal demand, in the middle of the northern hemisphere. As Bloomberg explained, the seasonality of crude has changed: it is no longer winter, but the summer months that mark consumption roofs. The big question is whether Poland can take this opportunity without repeating the mistakes of the past. The window is open. But it will not be forever.

What should you do if you find one in your mailbox

by

Phishing has been a problem for many years. Every time we find more sophisticated techniques To try to pique and do with our data or violate the privacy and safety of our devices. In this case, it seems that tactics have evolved, taking advantage of the postal mail of our house and thus skipping all the filters of the usual e-mail customers. The play that we are going to talk about next has been meeting a few years and more and more users who have informed of it are. It is a tactic that seeks to imitate Amazon through a promotional card in which they promise free products and commissions of up to 40 euros in exchange for scanning a QR code. It is a trap Internationally located of which we have seen examples in the United States, the United Kingdom, Germany, France and even in Spain. A new modus operandi. Criminals send physical letters with the Amazon logo in which the recipient is invited to join an alleged “test club” of new products. The letter promises free items and a commission that can reach 40 euros, as seen in several of the examples that circulate through Redditand in this Another user. The letter maintains that, to participate, we must scan a QR code that supposedly allows “registering the name and contact information.” The final hook is a suspicious contact email. Click the image to go to the publication Why this scam works. That postal mail is used instead of using e-mail in this practice is an intelligent decision by scammers. Physical letters generate more confidence than electronic messages, especially in older people less familiar with digital scams. In addition, they avoid all Antispam filters and security systems that block fraudulent emails. The QR code adds an additional layer of difficulty detecting the scam, since it is not possible to see with where to redirect the link. An international problem. This fraudulent campaign has been detected in numerous countries. According to experiences that other users have shared, identical letters They have appeared in the mailboxes of the United Kingdom, Germany, France, and even Spain, always with the same format and similar promises. Knowbe4 cybersecurity company has identified This technique through one of its employees, who also received this letter. The company contacted the scammers to learn more information, revealing that the plot could only mean a new method to transfer funds illegally, a fake review campaign, and other similar scams. If you receive it, ignore it. Amazon never contacts potential customers via postal mail not requested to offer test products. The company has specific official channels for its testing programs, which require prior registration and never promise cash commissions. In fact, as we can see, the contact email does not correspond to any official Domain of Amazon. The company has a website where they report what to do if we have been victims of ‘Brushing‘, the scam in which we receive an unplayed package or letteran increasingly common tactic. Throwing the letter directly to the trash without scanning the QR code or responding to the email is, surely, the best you can do. Older people and those less familiar with the Internet and technology are the objective of greatest risk in this type of scams, so It is convenient to run the voice to make sure they are also aware and thus avoid falling into the trap.

We thought that interstellar travelers were impossible to find current technology. Three have already been discovered

by

Less than a decade ago, the idea of ​​detecting an object of another solar system through our neighborhood was science fiction material. Astronomers were clear that they existed, but believed that our chances of detecting them They were practically null due to the limitations of current technology. In 2017, everything changed. First appeared 1i/ʻoumuamua. An object that baffled astronomers. Not only because it was the first interstellar object discovered in our solar system, but because its nature was and remains a mystery. With A strange formas elongated as a cigar or flat as an album, and a size of just 100 or 200 meters, it happened fleetingly leaving more questions than answers. Was it a comet, an asteroid or something completely new? The debate continues while moving away from us. Then 2i/Borisov was discovered. When we still wondered if we would see something similar in our lives, the answer came alone. In 2019, astronomers They detected a second object of another star system That was unequivocally a kite, somewhat larger than its predecessor (about 400-500 meters) and with a very different trajectory. Borisov confirmed that ‘Oumuamua had not been an anomaly. Interstellar visitors were real and we are able to find them. And to confirm it, 3I/Atlas arrives. On July 1, 2025, the Telescopes of the Atlas Network in Chile detected the third known interstellar object. After confirming your hyperbolic trajectory, He was officially baptized as 3i/Atlas. It is a real giant compared to the previous two, and marks a before and after in the study of these bodies. Like Borisov, it shows a clear comment activity, with a comma and a tail that lengthens as it approaches the sun. Therefore, it is a kite. But it is much bigger. Although the measurements are refining, initial estimates place their diameter between 5 and 20 kilometers. A colossal size that makes it much easier to study. A giant who will pass through Mars. 3i/Atlas is incredibly fast. It moves at an exhaust speed of about 58-60 km/s with respect to the Sun. much faster than ‘oumuamua (26 km/s) and Borisov (32 km/s). His career is also unique. It will reach its closest point to the Sun (its perihelium) on October 29, passing between the orbits of Mars and the Earth. Although at that time our planet will be on the other side of the sun, which will prevent its direct observation, it will be only 31.4 million kilometers from Mars on October 3. This opens a fascinating opportunity: that some of the probes that orbit the red planet, such as the Mars Reconnaissance Orbiter, can capture images of the interstellar traveler. Three important findings. Each of these objects is a time capsule from another solar system. All planets, asteroids and comets of our system share a common origin, but these visitors are authentic outsiders. They contain clues about the formation and composition of worlds that orbit other stars. Studying them is like receiving a geological sample from a corner of the galaxy that would take millennia to visit. Until now, we could only observe his fleeting step. But this is about to change. ESA is already preparing THE MISSION INTERPECTORwhose launch is scheduled for 2029. The idea is ingenious: the probe will not have a predefined objective, but will “park” at a point in Lagrange (L2) waiting for a pristine kite of a long period or, with some lucky, a new interstellar visitor to be within its reach. It would be the first rapid response mission to intercept one of these mysterious objects. In less than ten years we have not known if they existed to actively plan how to send a ship to touch them. With new generation observatories such as Vera Rubin, which is expected to find dozens of them in the next decade, we are entering a new era of astronomy. The universe sometimes brings us its secrets at home. Image | The interstellar comet 3i/Atlas (ESA) In Xataka | There is a single opportunity in 11,000 years of reaching the planet Sedna.

find all the exoplanets that we can

by

While there are still people who do not finish seeing with good eyes that Pluto is not a planet, astronomers have been compiling an extensive list of exoplanets. How many exoplanets includes this list? Many, thousands of fact. The number of exoplanets that we discover grow month by month. Exoplanets passionate many for different reasons, but with total security, the most widespread reason must be the possibility, remote but real, that one day we will find life in one of them. The more exoplanets we identify and study, the greater the probability of running out of our planet and our solar system. But let’s start with the basics: What is an exoplanet? Well, an exoplanet is essentially a planet, with the only peculiarity of orbiting a star other than ours, although there is something to clarify in this. Because The definition of a planet is that of a spatial object that orbits a star but that must have two additional characteristics: one, sufficient mass to acquire a spherical shape; and the other, also to be of sufficient size to clear their orbit of similar objects. This last criterion is what made Pluto lost the planet category. Check if these criteria are fulfilled, at distances of thousands of light years, it is difficult. The smallest exoplanets discovered, as Kepler-37bthey have a size similar to that of the moon, so we can assume that they are spherical. The problem is that it can become more difficult to check if an explanet of this size is accompanied by a similar but more difficult object to detect in the same orbit. Types of exoplanets Study objects at such distances is complicated but we know that they are not very different from those that we can find in our environment. That is why we usually classify these distant objects using analogies Based on the planets that we know best. The smaller exoplanets usually enter the category of rock exoplanets or terrestrial. These exoplanets are similar not only to Earth but to planets inside the Solar System such as Mercury, Venus or Mars. The next category would be that of superstierras, rocky planets such as ours but larger. Sometimes this category It intermingles with the subcategory of the mini-neptuna. The following category is that of the planets similar to Neptune, also comparable in size to Uranus, these planets normally have atmospheres full of hydrogen or helium, mini-neptuna are sometimes also classified in this category. Finally we have the gaseous giants similar to Jupiter and Saturn (or even larger), which sometimes includes the subcategory of the “hot júpiteres”. The closest If we want to find an exoplanet we don’t have to go very far. In astronomical terms, of course: the closest exoplanets of which we have news orbit the stars closest to ours, next Centauri. This system has at least one planet, next Centauri B, and also with at least one not confirmed partner, next centauri d. In theory there could be even closer exoplanets, although they would be virtually impossible to detect. For a few decades we have proof of the existence of wandering or interstellar planets, objects of mass similar to that of a planet that does not orbit any star but also but They roam the galaxy. The most similar to Earth The answer to the question of what is the exoplanet most similar to Earth depends on the criteria we use. The size and its position in the “habitable zone” of the star orbits are the main criteria that we can establish to determine the degree to which a planet can be similar to ours. The dough is usually related to the fact that this planet has a rocky surface, while the fact that it is in the habitable area implies the possibility that the planet has liquid water like ours. Following these criteria, We can highlight for example Kepler-1649c. Located about 300 light years from our planet, Kepler-1649C has a mass 1.06 times that of the Earth and, although it receives about 75% of the solar energy that reaches our planet we can place it within the area of ​​habitability of its star. Another good candidate is Kepler-442b. It is located at 1,194 light years of the earth and is 33% greater than the Earth, but its orbital situation would allow not only the existence of water but also the photosyntos. Special mention deserves next Centauri B, the planet closest to Earth is not only in the habitable zone of its star, it also has a size relatively similar to ours, 27% higher in mass. How many exoplanets are there? Let’s go back to the question we started, how many exoplanets we have discovered. According to the most recent data available, NASA’s exoplanet file list It includes a total of 5,926 exoplanets. Something more than a third of them, 2.28 specifically, They are classified As similar to Neptune, and only 217 are categorized as “land” (although the number of superstar is much larger, 1,741). However, we have only torn the surface. To the list of confirmed exoplanets we can add one, even greater, of candidate objects, more than 15,000 in total. And again this is only the beginning: our galaxy has tens or hundreds of billions of stars, we do not know how many of them could house planets. In addition, almost all the exoplanets discovered so far are found precisely within the Milky Way, so we do not know anything about the number of exoplanets that could be orbiting in the observable universe. Is there life in exoplanets? The big question that many have asked ourselves numerous throughout our life still has no answer. The possibility of life in solar systems distant from ours grows with each new discovery but we still have no evidence of the existence of life, even less intelligent life, on planets outside our solar system (or in another other than ours). However, The search continues. In Xataka | Star rains, planetary alignments and lunar phases: … Read more

After years of debacle, South Korea has managed to rebound his birth. Now it’s time to find out how the hell has done it

by

Demographic statistics is nothing more than that: Demographic Statistics. Pure and hard mathematics, with objective and reading data. For years, however, their chronicles in South Korea transmit a dire air, as of announced death. And it’s normal. The country has seen how its birth rate descended to such low dimensions that in 2024 the country had to declare itself in “demographic emergency” and assume officially that it is a “society Super aging“ Now that seems to be changing little by little, which raises two questions: Has Korea achieved out of the demographic hole in which it has been immersed for years? And if so, how? They are key issues for Seoul, but also for other neighboring countries with birth problems, such as China either Japan. What happened? That against all forecast, South Korea Start to get used to to their demographic statistics arrive accompanied by positive signs. That does not mean that they are good at all, the country has managed to stop its demographic bleeding or its fertility rate stands above “Replacement level”; But they are favorable news after all. And that did not happen for a long time. A figure: 20,717. The latest data published by Statistics Korea show that in April they were born in the country 20,717 babies8.7% more than 19,059 counted during the same month of 2024. The data is interesting because it leaves several positive readings. The first is that three years ago the number of monthly lights remained below the 20,000 barrier. The second is that this 8.7% growth shows the highest year -on -year increase in the last three and a half decades. You have to go back to 1991 to find another similar percentage. More babies, more weddings. There are not only more babies. There are also more couples giving the ‘yes I want’. The data Statistics Korea show that in April 18,921 marriages in the country were formalized, which leaves an interannual increase of 4.9%. The data invites optimism for another reason: it is the thirteenth consecutive month in which this indicator is green. It may seem a minor issue, but in the South Korean society couple and birth They go hand in. There are studies that calculate that less than 5% From babies they are born out of marriage. Coincidence or trend? That is the question that surveys the birth data of Korea. Especially since the last years have been marked by the shadow of the pandemic, which modes to take many couples to postpone their wedding plans or even the decision to become parents. In his favor the country has to They are not the first in positive. Seoul already said goodbye to 2024 with a positive birth rate (the number of births 3.6% increased), something that had not happened for a decade. Looking for the causes. At this point, the question is obvious: beyond the influence of the pandemic, is there any factor that explains the rebound in birth in the country? The question is interesting for South Korea, but also for other nations that have been dealing with demographic challenges, such as Japan, China, Russia or many European nations, including Spainwhich in recent years has gained population thanks basically to foreigners. “The increase in births seems to be influenced by the increase in marriages since last year, the growth of the population of women between 30 and 39 years and various birth promotion policies by central and local governments,” Clarify Statistics Korea to the Yonhap News agency. In summary, after the birth rebound in Korea there would be three major factors: more weddings, the effect of the ‘Probebé’ policies and that in the country there are more women in the first section of the thirties. A concept: echo boombe. At least part of the demographic change would therefore be explained thanks to demography itself. And the key is in a certain group of the cohort of the echo boomers. The Guardian remember That the population born between 1991 and 1995 begins to reach the “ideal” age to marry and have children and that group has grown sensitively. If in 2020 there were about 1.51 million women between 30 and 34 years old, now there are already 1.65 million. To its possible effect, the wide range of policies that for years have deployed the South Korean authorities (both regional and state) to encourage the formation of couples and birth rate are added. And that includes from the delivery of generous ‘Baby checks’ to the application of Fiscal incentives, parental permitsinitiatives for Improve food of mothers or even appointment programs (with prize included) to form new couples. Well but not perfect. The latest data from Statistics Korea are good, but they are far from being perfect and of course they do not allow South Korea to launch the bells on the flight. On the contrary. Although birth is emerging, the country’s fertility rate remains at 0.79far from the replacement level that the country needs to keep its population stable without depending on immigration. In addition, although the number of births with respect to 2024 has increased, they remain clearly insufficient to stop the fall of the national census. The reason? Babies are born, but in the increasingly aging Korean society there are also more deaths. The deaths grew 0.8% year -on -year in April until adding 28,785.
