Mexico had its own Alcatraz 130 km from the country. Fortified islands housed the most dangerous murderers of the nation

In December we rescue A true story which possibly served Michael Bay for his film ‘La Roca’, set in Alcatraz prison. Actually, it wasn’t so impregnablebut the jail (now converted into a tourist visiting space) has become notic again because Trump considers The idea of ​​recovering it as “home” for the most dangerous criminals in the United States. The truth is that, before Alcatraz, Mexico already had such a prison. From prison to sanctuary. For more than a century, The Marias Islands They represented the confinement, exile and hardness of the Mexican Penitentiary System. A story that changed from the definitive closure of its prison in 2019, when the remote archipelago in the Pacific began a surprising and unexpected transformation towards ecotourism and environmental conservation. Located about 130 kilometers from the coast of Nayarit, the four islands, and in particular Mary Motherthey went from being the last Insular Criminal Colony from America to become a Biosphere Reserve managed by the Mexican Navy. In 2022 the visits organized for tourists began under strong security measures and with limited routes, where visitors can travel both the wild nature and the historical traces of a prison past plagued with dark stories. Penitentiary facilities still visible (such as cells, surveillance towers and a maximum security module) are now combined with hotels, trails, lush vegetation and endemic species that have survived thanks to isolation for millions of years. Violence, punishment and resistance. Founded as Prison in 1905the Marías Islands housed many of the more dangerous criminals of the country, together with political dissidents, poor peasants and religious leaders during different historical stages. There were also opponents of the Government of Álvaro Obregón, Catholics in the time of the Cristero Warand figures Like the writer José Revueltassymbol of intellectual dissent. The prison regime varied over time, since semi -liberated modalities in which some inmates lived with their families, even closed structures such as Maximum security section Open in 2011 after the militarization of the criminal system during the war against the narco. In these facilities, described as replicas of American prisons, prisoners lived with extreme punishments, such as the existence of a metal cabin that functioned as a solar heat torture chamber. In fact, The BBC counted that rumors of undercover executions and clandestine burials are still persists in the other islands of the archipelago, occasionally frequented by illegal and drug traffickers. Overpopulation During the last decades of operation as prison, serious overpopulation episodes were experienced, particularly notorious in the 2000s. The angels Times counted and testimonies collected by Mexican media Like the universal and Processat some times they came to live More than 8,000 inmates In precarious conditions, in facilities originally designed to house much less. An especially shocking example was reported by a former inmate who, in 2022, recalled that 500 women They shared only five bathroomssituation that described how to live in a “chicken coop.” Although as we said, in the beginning the prison had a relatively open regime (even allowed some inmates to live with their families), the hardening of the penitentiary policy after the War against drug trafficking In 2006 and the opening of the maximum security module aggravated overcrowding. Complaints of insufficient rations and lack of medical care derived even in A riot in 2013after which the module closed. The combination of structural deterioration, lack of resources and social pressure ended up leading to definitive closure of the prison in 2019. Biodiversity Then came the “second life” of the islands. Despite its gloomy legacy, the natural wealth of the archipelago has survived and even flourished. Since 2010, when the prison still worked, UNESCO recognized the Marias Islands as a biosphere reserve for its unique ecosystem, composed of dry forests, mangroves, coral reef, coasts and endemic fauna such as the Loro Tres MaríasMapaches and rabbits that do not exist anywhere else on the planet. Many of these species suffered during the penitentiary period (they say Some inmates hunted snakes to make belts or trafficked parrots with the help of relatives). Today, the National Commission of Protected Natural Areas (Conanp) works with the Navy to protect this biodiversity, although the challenges are maintained, especially For illegal fishing. Despite the restrictions imposed since 2000 and reinforced in 2021, scientists such as Marino Octavio Aburto-Opeza Biologist warned that Companies still operate that offer recreational fishing or with harpoon without effective control, which puts at risk the fragile ecological balance of the area. Tourism (responsible). Today, visits to María Madre have become a strange mixture of biotourism and historical memory. Tourists, mostly Mexicans, are attracted to both the wild and The history of suffering inscribed in cells, corridors, murals and cemeteries. It explained the BBC With examples, such as the tomb of “El Sapo”, an alleged state murderer Macheted killed For their cell partners, or the esculos of octopus made by inmates who decorate still closed rooms, episodes that generate an environment between the surreal and moving. In short, although the current approach gives priority to contact with nature and environmental education, the main attraction for many remains the same as in Alcatraz: the possibility of walking for what was once a penitentiary hell. Thus, in the experience of the visit two stories live together: that of an infamous prison that functioned as a tool for social control and repression for more than a century, and that of a resilient ecosystem that now seems to offer a promise of redemption through responsible tourism and collective memory.

It is a fight to improve the quality of life

Throughout the existence of our species, we have given menopause, an unavoidable stage of women’s life, for some bearable, for others more suffered. However, the last decades have served us to learn a lot from female reproductive health, and that learning has opened the door to something that would seem unthinkable: delay and even end menopause. To fight something, the first step is to understand it, and perhaps we are not bad to clarify this concept. Menopause It is the stage that marks the end of female reproductive life, but leads to a series of changes that go beyond the mere end of menstruations. Menopause It usually occurs In women aged between 45 and 55 and is the process marked by the end of women’s reproductive capacity. The term “perimenopause” is often used to refer to the transition period, a period that usually extends several years. During perimenopausechanges are experienced both in the menstrual cycle, which can be lengthened or shortened; and at the level of estrogens produced by these organs. Progesterone production also falls. “Unlike other organs, ovaries experience accelerated aging, with a drastic drop in its functionality that begins in the 30,” explained to National Geographic ZEV Williams, director of the Fertility Center of Columbia University. Menopause not only implies internal changes but also has very palpable effects for those who go through it. Sophocals are perhaps the symptom that we most strongly associate with this process, although all symptoms depend on the case. The List of symptoms Common includes, in addition to changes in menstrual regularity and suffocation, strong or accelerated heartbeat, night sweat, skin redness, or sleeping problems. Changes in the vagina that take pain during sexual intercourse, urine escapes and more frequent infections can also occur. Menopause is not common in the animal kingdom: only a few species reach the end of their reproductive stage throughout their lives, which has intrigued experts for years. Does it make any evolutionary sense? The truth is that we do not know, so there are different hypotheses to explain this phenomenon. One of them is the Grandma’s hypothesis. This hypothesis proposes that living after the reproductive stage could have helped our ancestors to take a role beyond the breeding of the first generation of descendants. That is, allowing grandmothers to take care of their grandchildren or other relatives without having their own children to attend. There are also those who believe that menopause is not due to our evolution but is the effect of our growing life expectancy. While it is true that the human being has a relatively long life expectancy And increasingly extensive, we must bear in mind that throughout history it would not have been strange to see women reaching the end of their reproductive stage. And yes, life expectancy at birth has changed a lot, but the life expectancy fulfilled an age has done it to a lesser extent. For example, in the 1840s, the life expectancy of a person reached at 10 was over 57 years. More than 60 once the 20th. Ending with menopause At birth, the ovules that will give rise to the next generation are already located in the ovaries. We might think that, as it is a limited number of ovules, stretching the amount of menstrual cycles would be impossible, but the truth is that the number of ovules with which it is born gives for several lives, since this number is Between million and two million of gametes. These are disappearing, but it is estimated that during puberty the number of oocytes is about 300,000. Menopause is not a direct consequence of the exhaustion of these cells but of the aging of the organs that house them, the ovaries. The possibility of delaying the aging of these organs opens a way to prolong their reproductive life and their endocrine role. One of the promising techniques in this context is frozen ovarian tissue. This is a technique designed to simplify the process of extraction of ovules in people with cancer who want to maintain their fertility after very aggressive treatments. The technique, still experimental, is based on extracting tissue from the organ, freezing it and then reimpling it, could open the path to delay the menopausal process. According to their developerswhen reimplanting the fabric, this could be reimplanted in successive sessions, gradually lengthening the fertile age of those who decide to submit to treatment. The developers of the technique published last year An article In the magazine American Journal of Obstetrics & Gynecology in which they detailed their proposal. The Rapamycin It is a compound that could help us to delay menopause without going through the operating room. It is a already known drugderived from a bacterium, Streptomyces Hygroscopicusand used in other contexts for their immunosuppressive and antiproliferative properties. Recently, a team led by Williams, tested this drug. The treatment starts from the capacity of this compound to inhibit a protein related to aging, called MTOR. The provisional results of the study They gave rise to optimismbut we would still be in early stages of the investigation. Often if we have wondered if we can do something we also have to ask ourselves if it is a good idea to do so. Or the less ask ourselves, and all this for what? The answer in this case can be as simple as improving the lives of people who are going through this stage, whose symptoms can lead to a loss of quality of life and whose consequences may be complicated to fit sometimes. But there is even more. Because trying to stop menopause can also serve us as motivation when it comes to understanding it better, which could lead us to solve indirectly linked problems. For example, we know that the late appearance of menopause It has been associated with a lower bone loss in the elderly, as well as a lower risk of vascular and dementia diseases. Know why it can be of great help when improving the … Read more

Fans legions by throwing money to their idols

Japan is not living its best moment, and much of that situation has to do with the age of its population. The Japanese demography debacle It is explained by the Lack of births and the population aging. The generational relief is the big doubt, young workers are missing and Soon you may also farmers. And before that perspective Not very flatteringits economy grabs the fan phenomenon. Or, as they baptized a few decades ago, to Oshikatsu. Fan phenomenon. He term comes from the union of “Oshi“, Or” favorite “, and” katsu “, or” activity. “The phenomenon is originated In the 80s with the beginning of the culture of idol or support for sports teams, but has exploited more recently thanks to anime, video games, teenage singers and even Vtubers and Virtual artists. Basically, it consists of leaving money in what each one likes, and covers from the purchase of merchandising to the assistance to concerts, events, purchase of anime and video games, directly donate to the idol or participate in increasing that fan phenomenon with comments in forums, social networks or creation of fan art. Among other things. Hey, this generates money. It is not exclusive to the youngest, since at any age we may like something to make it a hobby and, in fact, a significant number of adults, especially women, contribute to that Oshikatsu very active. That of adults is the demographic group that, for issues of greater possibility of having a job, more money can invest in what it likes and It is calculated that, in 2024, 46% of women in their 50 had a Oshi to which they supported financially. And that they have noticed from the political spheres. So much that this practice is consolidating as something to take into account in the economy of entertainment and consumption in Japan. HE esteem that the expense is 3.5 billion annual yen, approximately 17,000 million euros, and there are already politicians who see the Oshikatsu as a possible engine of economic growth. A lot. This increase in importance has impacted even labor policies, with some companies offering paid permits to employees when they are going to perform a practice that is included in the phenomenon. And from the Covid-19 pandemic, the digital one thanks both to both NFTs and virtual leisure such as digital concerts. And the individual expense in the Oshis? According to a recent survey in Japan, the average amount that fans spend on activities related to their idols is about 250,000 yen. This is about 1,600 euros per year and, with the advertisement Of recent increases, they are expected to invest even more in their Oshis. We are alone. Now, as usual, there is a darker story behind Oshikatsu. As we read in The conversationa 2022 investigation evidenced that these fans activities are related to a deep desire for connection, validation or belonging to a group. Also of personal connection and we might think that it is satisfied by friendship or a more intimate relationship, but there is a problem: the rhythm of life. Young men lead that trend, especially those with manual jobs or part -time that have difficulty combining personal and work life. Therefore, they do not have time to cultivate and keep friends. And that is giving rise to another business: pay for hours to relieve loneliness. Rent humans for hours. Because there are companies that are already seeing that opportunity to turn something like friendship into a product. As? Hiring people to be your friends for a day, something that implies from going to the park until giving hugs without other connotations. The big problem? Convert that human connection into some payment. And beyond business, there are other economic implications, such as people who have a second job to be able to “keep” Oshis. Good side. But it is also something that has its positive part. Precisely, being part of a phenomenon, you are likely to find on social networks, forums or fan club with those same tastes with which you can develop a potential friendship, thus satisfying that affective need. On the other hand, it remains to be seen if that phenomenon is the great promoter of the Japanese economy, since an important part of the phenomenon is the culture of content creation, such as Fan Art, which is shared for free, as well as the clubs and events in which the participants meet to show their interest in the same topic. Although we focus on Japan, in the West we will not have such a cool word to describe the fan phenomenon, but it is something that We see daily with fans clubsthose that align with certain hobbies on social networks and even those who directly support their favorite creator through donations on platforms such as YouTube or Twitch. And the Japanese demographic problem … Nor is it exclusive to that country.

Valencia feared that the housing market sink into the areas devastated by the DANA. The opposite has happened

The Dana that He hit the province From Valencia in October it was so violent, it caused so many damage and affected so many people, that in the real estate agencies of the area they feared that the market was upside down. “It was thought that it was going to sink into the most devastated areas,” Recognize The sector. Reality has been another. The region has not only maintained The tension Between supply and demand suffered before the Dana, but has added an extra factor: Damage who suffered hundreds of households. The Association of Real Estate of the Valencian Community (ASCival) has published A report It helps to better understand how the market has responded. “We saw that the demand was strong”. Nora García Donet, president of ASCival, acknowledges that the market response after the Dana has even surprised the sector. After the rains they feared a puncture in the market, but reality has been quite different: the demand remained high while the offer (which in many cases was already subject to intense pressure before disaster) It was marked by the loss of households razed by rain and mud. “In the first moments it was thought that the market was going to sink into the areas most devastated by the Dana, but soon we saw that the demand was strong in a context in which many homes had been inoperative, and this trend is the one that has been maintained over time,” Donet points out. That equation has ended up moving to another key element: prices. A percentage: 18%. The report Ascival provides a fundamental fact to understand the drift of the market: the price of housing has increased by 18% in the municipalities hit by the DANA. More specifically 18.8% in the sale market and 18.1% in the lease. Translated to counting and sound money that means that houses for sale in the affected areas cost 171,428 euros while the rentals are around 800. The provinces has deepened Something else and calculates that a floor for sale in the towns razed by the downpours has increased, on average, about 32,000 euros. In the case of homes for rent, the price increase would be at 145 euros per month. All compared to the values ​​of seven months ago. What is the reason? The same that usually causes price increases in normal conditions: the imbalances between supply and demand. In Your study Ascival indicates a growing decoupling between both both in the sale market and in the rental. In the first case, the association calculates that the demand for houses for sale has shot 22% while the offer has fallen by 31.3%. In the second case, that of the Property Market to lease, the demand has shot 27.1% with the offering supply (38%). “Little more than six months after the devastating consequences of the DANA, the real estate situation in the affected municipalities follows the same trend of price and demand and contribution trend and contrition of the housing supply as in the rest of the Valencian territory,” Point out As a conclusion the Asicval report. That reality is verified by the region’s own agencies. More than half (54.3%) ensures that the supply of housing for sale has decreased and almost 90%(87.5%) have noticed price orange blossom. 58% also believe that there is more rental demand, while 96% consider that the supply has been maintained or dropped. The role of the Dana. The report It does not detail to what extent the increase can be related to the effect of the DANA or its influence on supply and demand, although it does slide some interesting data. The main one is that most people interested in buying or renting a house in the affected municipalities are locals. This is perceived at least by the agencies, which also ensure that customers do not seem especially interested in knowing whether or not the properties are in flood areas, but they do prefer apartments in height buildings. The tension in the market is not new, nor has it emerged after the October disaster. In 2024 Idealista published A report in which he already pointed out that the district with the greatest pressure in the demand for housing in Spain was in the Central-Horte de Trenor area, in Torrent. During the last months the house It has become more expensive Also in the whole of the province of Valencia, not only in the areas affected by the DANA. What the torrential rains did was sweep hundreds of homesdamaging them or leaving them temporarily uninhabitable.

Cybertruck wanted to be the car prepared for the Apocalypse. Lamborghini Rezzvani Knight has advanced him on the right

You’ve ever thought about “how good a tank would make me buy the bread.” If the answer is affirmative, two things: what would you have to comment with someone … and there is a car for you. Whenever you have a baggy bank account, of course. The reason? American firm Rezzvani has created the Definitive SUV For apocalypse: a Lamborghini Urus that seems Christopher Nolan’s Batmobile. They have baptized him as Rezvani Knight, and even calambrazos who dares to touch him. Rezvani. This is a story of two firms aimed at being. One for its radical designs and another for the personalization that adds to the cars that pass through their workshop. Let’s start with Rezvani. It is a American manufacturer which has focused on converting high performance cars into something extremely exclusive. What they do is choose a supercar or powerful off -road and improve both base vehicle benefits and occupants protection. In the presentation of Tesla Cybertruck Emphasis was placed on the armor of some of its parts (Do not glue them with glue), But in the case of Rezvani models, they literally create armored vehicles. He Beast Alpha X Blackbird or the HERULES 6X6 They are two examples. The Urus. On the other hand, we have the Lamborghini Urus. The Italian firm does not need presentation at this point and one of its last creations is a SUV High performance equipped with a V8 biturbo engine that develops about 650 hp. This 2025 Han launched a plug -in model with a total of 800 hp by adding a 192 hp electric motor. It has an even faster acceleration, total traction and 8 -speed automatic change. It is a car that aligns, standard, with the aesthetic vision of Rezvani thanks to combining that typical bull brand with sports lines and high performance engines. The original Explosive mixture. And, condemned to understand each other, the Rezvani Knight. This name makes a lot of sense because, basically, it is a mixture between a lamb and a tank, exactly what Nolan devised for the Batmobo that Christian Bale leads in his Batman trilogy (the personal car when he was not Batman was a Lambo batby the way). The Rezvani Knight widen its body and add 22 -inch tires, a led bar on the ceiling, front lights divided into four and more angular and extreme lines than those carried by the URUS standard. It seems that they have taken as a reference the hybrid version, since they do not give details, but they claim that it has 800 hp. And the really striking is what hides. The Dark Knight Military Package carries the following extras: Chapa armor and crystals not only for bullets: also for explosives and grenades. Reinforced suspension and military tires with antibala protection. Doors with electrified handles, blinding lights, air filtering system against chemical agents, smoke dispensers and pepper gas, anti -strap defenses and even protection against electromagnetic pulses. Thermal cameras and, as accessories for occupants, gas masks and bulletproof vests. Price … dizzy. To the question of “how much this monstrosity costs”, the answer is “yes.” First, you have to contribute the car to modify. Urus costs about 260,000 euros and you must donate yours to the cause. Second, the conversion starts from $ 149,000 with external design, military gadgets and survival and partial armor. Third, the most extreme armor is revealed to whom one reserves. Because, in addition, it is limited: the idea of ​​Rezvani is to manufacture only 100 of these monsters worldwide, so if it is already a expensive car with a face modification, that aura of exclusivity can make that in the future it costs an authentic fog. Or maybe, as happened to ASVE AREX, unique in the world and Sold for what a Dacia Duster costs. Images | Rezvani, Alexander Migl Images | A youtuber has a car that is worth four million euros.

A V3 engine that is about to return to life

Honda is Honda. A said biker that the Japanese has earned by doing things well for almost a hundred years of history. In the 80s, Honda won the 500cc World Cup with an engine that had never developed. One of the most famous in history, practically impossible to replicate. We talk about a very special three -cylinder engine: the V3. The first V3. NSR400. The bikers with more solera may still be her skin with this name. Is the denomination of One of the Honda sportsmen produced between 1985 and 1988although he never landed in Spain. An engine that cubicated 387cc … with two cylinders arranged in parallel and one in vertical disposition. Honda thus invented the V3 engine, one that allowed to manufacture a motorcycle with more power than a bicylindrical and lighter than a tetrachindric. A motorcycle that inherited the design of the NS500 world champion in competition, and whose only sin was the technical complexity to maintain its engine. As a curious fact: the NSR400 had three escapes: two for the even cylinders and one for the remaining one. This was the curious structure of Honda V3. The mess with the cylinders. There are four traditional engines in the motorcycle industry: mocylindrícos, bicilindric, tricylindrical and tetracylindrical. BI and Tetra are the most common in the middle and high displacement, due to their structure of even cylinders, easy balanced and low production costs (especially in the case of bicilindrical). There are those who define the tricylindrical (in motorcycles) Like the perfect engine: With the best of performance in high revolutions of the tetra, and the thrust in low and media of the BI. Manufacturers such as Triumph have been betting on them for years, and just landed as zontes. Returning to life. Honda has confirmed that Your V3 engine will return to life with a much more modern configuration. One in which the world’s first electrical compressor will be equipped for motorcycles. Kawasaki was the first brand in the world to equip a street motorcycle super charger such as H2 and H2Rbut it is a mechanical engine driven, not electric. With the Honda electrical turbocharger wants to achieve a huge power, although no data on its displacement has yet been offered. What we do know is that it will be extremely thin and compact, designed for sports motorcycles. Thinking about Euro 5+. The emission regulations They are increasingly restrictive, but Honda has thought about it. The company ensures that its V3 will not only be especially competitive in performance, but also in escape gase emissions. “We will continue to develop the new generation of internal combustion engines to achieve serial production, so they look forward to the arrival of this new generation.” Minoru Kato, director of the Honda Power Motorcycle and Power Products Business Division. De Honda not only clashes that they are thinking of bringing to the market one of the most complex engines at the mechanical level of history, but continue to invest in new combustion architectures oriented to the maximum performance.

They asked Bill Gates and Warren Buffett how they would define their success in one word. They did not hesitate: focus

At 94, Warren Buffett Ha “Hang” your investment notebook After more than six decades as one of the brightest and most accurate investors of Wall Street in front of Berkshire Hathaway. For his part, Bill Gates spent four decades directing Microsoft. Both became Milmillonarios with it and agree that they would never have achieved it if it is not for a key factor: to focus on achieving their goals. Focus on something and be constant. In one Interview for CNBCBuffett said that on one occasion Bill Gates gathered a group of 20 people – among which Bill Gates was – and asked them to write a word that explained their success on paper. “Bill and I had only seen each other twice and we didn’t know what the other was writing. We both wrote the same word: ‘Focus‘” Both Bill Gates and Warren Buffett attribute much of their fortune and legacy to their ability to avoid dispersion and keep the course for decades. For them, the approach and the ability to focus on a single objective is not only a skill, but the basis on which their empires built. While others played, Gates scheduled. As detailed in his autobiographical book ‘Code Source: My beginnings’Adolescent Gates discovered that programming was a creative way of structuring ideas that tests their logical thinking, which made it become obsessed with creating different programs when access to a computer was a scarce resource only reserved for universities and large companies. Gates and his companions of the “Computer Fourth” of high school managed to get free shared access time to one of those expensive computers and learn to program when very few knew how to do it. This obsession with the software has provided a fortune valued at 112.7 billion dollars, according to Forbes Start is an advantage. In An interview For Charlie Rose’s program in 2016, Gates said that “what you do obsessively between 13 and 18 years is what is most likely to take you to global success. The only thing I did obsessively between my 13 and 18 was to write software.” According to Buffett, in the same way as Gates He focused on learningHe did it to learn to invest. “He focused on software. I concentrated on investments. Starting very young gave me a great advantage. There is no doubt about it,” said the investor nonagenarian. According to Times of Indiaat 11 years the “Oracle of Omaha” was already beginning to make his steps in the investments with $ 114.75 that he had saved. With them he bought three actions from the CNIES Service oil and gas company (now called Citgo). Bill Gates became a millionaire at age 20 thanks to the software company he had founded with his secondary school friend Paul Allen. Warren Buffett had to wait until 32 years for his heritage to exceed six figures. Prioritize and avoid distractions. Having clear priorities has been essential for Gates and Buffet not to waste energies in projects that did not bring them closer to their goals. Bill Gates told to CNBC that He had focused all his life In a single project: Microsoft. During his first 20 years leading Microsoft, his routine revolved exclusively around software development, sacrificing weekends and vacations to achieve its goal: that each home had a personal computer. In An interview for Vanity FairPaul Allen, co -founder of Microsoft and Gates’s partner in its beginnings in programming, said that “Microsoft was an environment of great stress because Bill directed others as hard as he did with himself.” Warren Buffett’s strategy: focus and long term. From a young age, Warren Buffett, chose to specialize in long -term investmentsavoiding the temptation to search Quick earnings. Your strategy During all this time it has been based on identifying solid companies, investing in them and maintaining the actions for years or even decades letting the Time and compound interest They would grow their money. Buffett calls this investment style the “snowball effect”. In the Annual Berkshire Hathaway Shareholders Board of 1999Buffett joked with his inverting precocity. “We started building this small snowball at the top of a very long hill. The key is to have a very long hill, either starting very young or living to very old.” The 94 -year -old veteran investor has met both conditions for Finish your career With the fifth greatest fortune in the world, with a “snowball” valued in 156.6 billion dollars.

Its solar panel in tandem already exceeds the theoretical limit of silicon

The efficiency of solar panels always andStá in object of studyand the only country capable of developing new advances is China. In fact, the company Longi has achieved have even a certificate of the National Renewable Energy Laboratory (NREL) of the United States. Short. The Chinese giant of the solar modules He has achieved A new record in solar energy conversion, reaching 34.85% efficiency in a pervskita solar cell in two terminal tandem. In this way, Longi has managed to overcome The previous 34.6% record that Longi herself held two years ago. A key technical advance. To understand the feat, it is important to know the tandem design. This structure combines an upper cape of Perovskita and a lower crystalline silicon, allowing to capture different ranges of the solar spectrum. Through a technique called bilayer interface passive, two layers are introduced that improve the passage of electricity between both active layers. On the one hand, lithium fluoride (LIF) acts as a barrier against load losses. On the other, the ethylendiamium diyoduro (EDAI) fills the nanometric scale holes, ensuring a more efficient load extraction. It’s not just about materials. The Chinese company has also redesigned the structure of the crystalline silicon, making the frontal surface more rough to facilitate the adhesion of the Perovskita and maintaining a standard texture in the rear to optimize the capture of infrared light. This texturing improves the absorption of light and, therefore, the efficiency of the panel. Achievement is not less. Apart from overcoming its own record, the Chinese company has overcome The so-called Shockley-Queisser limit. In other words, it has managed to exceed the maximum efficiency limit marked by 33.7% for a single union. However, tandem cells, which combine different materials such as Perovskita and silicon, can overcome this limit by taking advantage of a broader range of the solar spectrum from the theoretical aspect. For example, research has shown that tandem cells can achieve higher efficiencies 40%and theoretically, some configurations could reach up to 60% . Institutional support. Thanks to the participation of the universities project such as Suzhou and Hong Kong (HKPU), together with the Huaneng Clean Energy Research Institute, They have allowed A Longi perfects its silicon hetero -union technology and optimizing manufacturing processes, bringing Tandem technology to a more commercializable level. The next challenge. Longi has shown that the solar efficiency roof remains a mobile objective. However, he will now have this laboratory technology to the mass market. The durability of tandem cells, production costs and industrial scalability They will be key factors To determine if this record becomes a commercial standard or another technical advance without immediate practical application.

A power in nuclear energy is emerging as the best alternative to Russia and China for the West: South Korea

Russia and China are indisputably two powers in nuclear energy. So are USA, France and other western alignment countries. Although these states have a bulky nuclear plant park which really places them at the forefront is Your ability to develop new technologiesand in this area the most promising reactors are The fourth generation. Russia and China already have at least A reactor of this type in operationand the US, France, India, Canada or Japan are some of the countries that plan to have them in the future. However, there is a power in nuclear energy that often goes unnoticed. We all know that South Korea has a lot of weight in semiconductor industries, consumer electron Nuclear energy as a strategic pillar Not only within its mix of electricity generation, but also as an engine of innovation and export. South Korea is the most consistent alternative to China and Russia Currently South Korea has 26 Nuclear reactors in operation with an approximate total capacity of 25.7 GWE. This infrastructure contributes to its Mix with 30% of electricity, although the commitment of this Asian country for nuclear energy does not end here. And it is that between 2026 and 2033 the construction of four more reactors will conclude that will have a power of 1,340 MWE each of them, so the total installed power in this country within less than a decade will exceed 30 GWE. Its APR-1400 reactors incorporate passive security systems that allow them to compete from you with the machines exported by Russia, China or the USA In any case, as I have anticipated a few lines above, which has placed South Korea to the avant -garde and has positioned this country as One of the largest exporters in the nuclear sector It is your ability to develop your own technologies. Their APR-1400 reactors incorporate passive security systems that allow them to compete from you with the machines exported by Russia, China or the US. In fact, South Korea has already exported this reactor to the United Arab Emirates and is negotiating with the Czech Republic and Poland to sell their technology. On the other hand, this Asian country has also opted for fourth generation nuclear fission. Your smart reactor (System-Integrad Modular Advanced Reactor), what is An SMR type design (Compact modular reactor) is in the process of certification to be used in desalination and electricity generation facilities. It also prepares fourth generation reactors refrigerated by sodium, such as the machine outlined in the Kalimer project, although it is not yet clear when the first South Korean commercial reactor endorsed by this technology will come into operation. South Korea has a very ambitious plan: wants to capture at least Ten international contracts until 2030. His first project abroad has been Barakah’s nuclear power plant in the United Arab Emirates, and It has been a success. As I mentioned a few lines above, Czech Republic and Poland are presumably will bet on South Korean reactors, but South Korea nuclear energy companies are also trying to take contracts in Egypt, Finland, the Netherlands, Sweden, Turkey and even in the United Kingdom. If only some of them get to fruition this Asian country will become a full competitor in the international market of China, Russia, France or the US.

Steve Jobs presented an emulator in 1999 to turn any Mac into a playstation. Sony did not even grace

January 1999. MacWorld Expo de San Francisco With Steve Jobs on stage. After a presentation loaded with video games and focused on how well those video games run in front of the PC versions, Jobs made Una of the most controversial presentations that have been seen in a scenario of a company of Apple’s reach: that of a PlayStation emulator. Steve’s goal was for each MAC to become a PlayStation I could run games like ‘Crash Bandicoot‘, something possible by the hand of a company called Connectix and of a software called Virtual Game Station. In an ecstatic Sony for the success of their console, they should not give credit to what was being affirmed in one of the most projection events worldwide. The punishment for the creators of the emulator? Be bought … by Sony. Turn each mac into a playstation In 1998, the field of video games for Mac was … Campo. In PC you could enjoy the Lucasarts great adventuresof ‘Warcraft‘, from’ Devil ‘, De’Age of Empires II‘And that same 1998 jewelry was born’Starcraft‘ either ‘Half life‘, But the situation in Mac was very different. There were some projects, yes, and companies like Bungie had interesting games such as ‘Marathon’, but the PC win was incontestable in the entertainment segment. A young programmer named Aaron Giles came up with one thing. Hey, if the MAC has a CD reader and the USA PlayStation CD, Why couldn’t a PlayStation game into a Mac? Giles worked for Connectix, a company founded in 1988 with a very curious story. They developed pioneer software for Mac, but with each new version of Mac OS, Apple ‘stole’ those functions that they had developed to include their own. What Apple did was buy Shareware versions of the same concept that Connectix developed, and so they did not have to make deals with the Connectix itself. Not only did they do hardware: they also took the mac from the sleeve Quickcamone of the First webcam in historythat They sold to Logitech in 1998. But the emulation was the strong point of this company and the focus of many of the developers of the same. Let’s go back to the history of Giles. The programmer began working on the project in 1998 and the truth is that, being able to read Sony’s games with a standard CD-ROM reader, the hardware part was solved. “Only” You had to focus on emulating the bios And the PlayStation environment, but by January 1999 I already had it ready. Thus, on stage, Jobs announced to the world the Game Station virtual emulator, or VGS. “Our goal is to have the best game platform in the world,” said Jobs, who showed below a photo of a playstation. “This is another video game console, the most popular at this time. Wouldn’t it be great if we could also play some of your games?” With that lapidary phrase, Jobs presented the Connectix product adding that it was an emulation software that would sell for $ 49 and that “turn your Mac into a Sony PlayStation.” Less than half of what cost a PlayStation. I imagine Sony’s executives spitting the sake when they learned that Jobs had said that. Hallucinatory “There are hundreds of games that can reproduce from the PlayStation,” said Jobs, who gave way to a Phil Schiller – world marketing director of Apple products – that did not reduce the enthusiasm or tone. Steve giving way to Phil before playing ‘Crash Bandicoot 3’ “This is very cool,” Phil began. The possibility of using a Mac, my MAC, to execute all the great playstation games quickly and economically only putting the game is a fantastic idea ” AND, Neither short nor lazy, he began to play ‘Crash Bandicoot 3’. “It is Sony’s most popular game at this time,” said Phil without cutting off a little (something that today is absolutely unthinkable) and … he began to play. That title had come out just a few months before and ran at 100% speed in a Mac (after a couple of pulls) simply by putting the CD and running VGS. The question was how. How they had been able to emulate perfectly in a IMAC G3 At 233 MHz an RISC processor at 33 MHX, being this of a completely different architecture. And the most impressive is not that, but Giles got it without using a Sony code line. Before continuing I will summarize How an emulator works. It is something that recreates the hardware and system of a console on another platform. In this case, a program that recreates a PlayStation in a MAC. The emulator makes “translator” In real time among the game instructions, which are designed for consoles hardware, to the instructions of the host device. It is something that consumes many resources because you must do a double job, but the really complicated thing is to emulate the BIOS. BIOS means Basic Input Output Sustm and is the essential software of the console that controls the start and interaction between the hardware and that console. For VGS to work, he had to emulate that bios. Giles contacted Sony to help them with the BIOS of PlayStation and, before the Japanese refusal (and an cessation and withdrawal letter by Sony), the programmer did something as absurd as great: thoroughly investigate the machine, study the original bios and rewrite it from scratchlike an own bios. It was absurd because it was a titanic task, but also great because Sony couldn’t do … nothing. Sony’s disbelief That same 1999, Connectix launched VGS for Mac and most games ran fantastically on Apple computers. There were characteristics, such as the vibration of the PlayStation command, which did not work, but it was something that impacted allowing, for 49 dollars, all the owners of a Mac have, in practice, a playstation. For sale of games it would not go wrong because a window of potential users opened, but as we said before, Sony should … Read more
