theory

Many heterosexual women say they are fed up with men. There is a theory that explains it: “heterofatalism”

by

In a city like New York – or Madrid, or Buenos Aires, or any city where a woman with quotes history and good Internet connection reevalu Spin-off Less glamorous of Sex and the city. One where the stories do not end in Manolo shoes and kisses in the rain, but in Ghostingsexcuses for anxiety and group therapy in dinner format. And it is not that Carrie Bradshaw did not warn something similar. In more than one episode, their columns revolved around a question today very close to what many women formulate from a more critical and collective place: heterofatalism. A term that describes the disenchantment, irony and resignation with which their love experiences with men look at. But it is a ismIs it a theory or just another bad appointment with academic name? Heteropesyism It was coined in 2019 By the columnist ASA beings, describes an attitude of hopelessness and resignation to heterosexual relations, especially from the perspective of women who, although disappointed, do not abandon those relationships. As He explained an article in The Conversationthis position “does not necessarily imply violence or hierarchies”, but rather “a worldly but persistent disappointment.” However, beings propose a more extreme version: heterofatalisma kind of resigned acceptance of heterosexual failure. As explained by Jean Garnett In an extensive article for The New York Timesis “the feeling that the men I want do not love me with enough clarity, urgency or commitment.” An amplified term There is a political and social context that exacerbates disenchantment. As Marie Solis points out in The New York Timesmany of these speeches intensified after the choice of Donald Trump and the confirmation of Brett Kavanaugh, perceived figures as symbols of sexist impunity. The #MeToo Movement, Although transformativedid not change the most daily dynamics of the appointments. In addition, social networks have amplified this narrative. Tags like #boysober, #selfpartnered or growing interest In movements like 4b (Rejection of relationships, sex, marriage and maternity with men) portray a generation of women who, although they do not always renounce men, have lost faith in the promises of heterosexual love. According to sexual Health Alliancethis gap is linked to how men have been socialized: with difficulty verbalizing emotions, Fear of vulnerabilityand in some cases, a rigid masculinity that associates desire with domination or detachment. Professor Ellie Anderson Talk about “hermeneutical work”a form of emotional exploitation in which women are responsible for interpreting the confusing signs of little communicative men. It also mentions the “masculine regulatory Alexitimia”, a structural emotional difficulty in many heterosexual men. For her part, the psychoanalyst Jessica Benjamin Talk about the “paralyzing complementarity”: When both parties in a relationship feel that they cannot gain recognition without losing power. All this composes an emotional scenario where, as Ironiza Garnett“A woman asks for clarity and is punished for ‘being too intense.” In a Newtral article, the journalist Noemí López Trujillo Lo has explained quite clearly: Connect the rise of heteropesis with a stretch of female sadness. Speaks of Femcelcore As a cultural current where women are portrayed as broken creatures, dressed in black and away from men as the only self -protection strategy. This romantization of the love duel, however, can fall into a sterile nihilism, which avoids all political or transformative action. ORna exclusively feminine experience? Although heterofatalism has been mainly theorized since the experience of heterosexual women, some authors warn that it is not completely unilateral. The Times points out that While women express this pessimism with irony and memes, heterosexual men are also experiencing a crisis, although with very different consequences. While they retract, they take refuge in communities Like incels or PERICAderiving his frustration in misogyny. In this context, in recent years the proliferation of male communities that feed a growing anxiety towards relationships and a replication towards the idea of “traditional love” has become more evident: stable couples under rigid gender roles, and a nostalgia for an alleged “golden age” – the 50s and 60s— 60— in which, with a single salary, “the woman stayed at home, they had three children and they were all happy.” This imaginary, reinforced by online forums and conservative speeches, Not only does it idealize an unequal pastbut it presents it as a remedy against current confusion and disenchantment. For her part, the Poppy Sowerby journalist, In The Timeshe warns that when women hold all men for their disappointment, without nuances, heterofatalism becomes the reverse of the Incel discourse. In both cases, the heterosexual relationship is presented as a tragic destination and without exit. There is a disjunctive present in this whole situation: is the desire the problem or the roles that frame it? One of the most relevant criticism of heterofatalism comes from within feminism. As Health Alliance has detailed sexualthis speech can end up naturalizing misogyny by equating it directly with heterosexuality. The problem, they argue, are not the men per se, but the gender roles that both – men and women – reproduce without questioning. Rachel Connolly, In The Guardianhe sees heteropessimism as “a conservative vision disguised as radical criticism.” Really all we can expect is that our partners do not throw their dirty socks? What kind of imagination do we have if we assume that heterosexual relationships are convicted by nature? Shon Faye, In his book Love in exileproposes something different: stop waiting for a couple to be everything. It raises a reorganization of relationships based on the recognition of our diverse needs –sex, conversation, care, finance – as potentially distributable, and not necessarily contained in a single romantic link. In short, the panorama that is presented is ambiguous. On the one hand, there is a growing awareness of the failed dynamics of heterosexual love. On the other, there is a scarce exploration of real alternatives. The challenge, According to Jessica BenjaminIt is not the resignation, but the encounter. To do this, it proposes the concept of “intersubjective third”: a mutual recognition zone where both parties are seen as subjects with desire, agency and vulnerability. It is … Read more

The not so far -fetched theory that argues that the cradle of Spanish football is in an unsuspected place: Vigo

by

In football not all matches are played on the grass. For years there is a struggle that is settled in the newspaper libraries, the archives and local chronicles of the Spain of the late 19ths: that of the origins of the origins of Foot-Ball homeland The most widespread version, the canonic and the one that Mention The Royal Federation (RFEF) on its webs Recreationalthe dean of national football. However, there is a theory that places the cradle of Spanish football at the other end of the Peninsula, in Galicia. To be more precise at the Vigo docks. What is the cradle of football? You may like more or less, but kicking a ball has always made us funny. The citizens of ancient Greece practiced a game called Episkyrosthe peoples of pre -Columbian Mesoameric had their popular Pok-a-tok And even the Vikings were fond of Knattleikr. If we talk about football as we know it today, however, the genesis of sport must be located later, in nineteenth century England. There, in him Mortlake districton the outskirts of London, a match between Barnes Football Club and the Richmond Football Club was held more than a century and a half ago than It would be crucial For the history of modern football. The reason? Its rules. Before, matches had been played, but with guidelines agreed by the teams themselves. The December 1863 was the first one that was governed by the rules of the newly created Football Association (FA), founded only a couple of months before. And when do you jump to Spain? The most widespread version ensures that football came to our country not much later, in the 1870s, via Huelva. And for reasons that have more to do with finance economy than sport. In 1873 it was established A company of British capital to exploit the deposits of the Riotinto Minera Basin and with it they landed in the British region that soon gave free rein to one of its great hobbies, football. South Canal remember That on August 16, 1873, coinciding with the patron saint festivities of San Roque, a match was already held in the town, “the first football played in Spain,” the local chain says. Of that set echoed A few years ago ‘Mines and Riotinto, cradle of football in Spain’, a work published with the support of the Diputación de Huelva, which would confirm that the first goal of Spain was sung in the small town of the region of the Mining Basin. And the first team? Five years later, in 1878, the Riotinto English Cluban association that facilitated that British engineers and sailors could practice sports such as Cricket, Polo, Pole Lawn-Tenis or the Foot-Ballwhich in turn referred to the creation of the Rio Rio FC. The recreational itself remember That there is a record of at least one match played in the province on September 10, 1874, an encounter between personnel in charge of the railroad tracks that linked Huelva and the mines and a gang moved to Gibraltar. Riotinto FC 1918. Sobple matter? Not at all. Years ago a Galician story, José Ramón Cabanelas, took a surprise while diving in the newspaper library of Vigo lighthousenewspaper founded in 1853. The expert was looking for documentation for a book on the origins of the Eastern Telegraph Company (the English cable) in the Galician city when he met a brief and irony passage that activated his historian instinct. The reason? What counts … and what suits. The text was signed by some of the chroniclers of Vigo lighthouse June 10, 1876, And tells: “Again they have visited us (to the casino) the English. They are as friendly! They walk like four, they step on six and drink like fifty. They fish, hunt, smoke, paint and play ball according to their use and way.” To any other reader the comment would have gone unnoticed, but Cabanelas remained a question: what did the English mean that the English “play the ball”? Are there British in Vigo? Yes. If in the 70s of the nineteenth century Mines de Riotinto had displaced British to take care of the exploitation of their mines, Vigo had them for another business as relevant: the management of the telegraph. Since 1873 the city welcomed offices of the Eastern Telegraph Companycompany that Vigo had chosen for its good location as access to the peninsula and the tranquility of its estuary. In fact, years later, in 1896, another similar company would also be established, the Deutsch Atlantische TelegrapheGellchaftthe German cable. Each arrived in addition to its patriot colony. And how important is that? Much, according to Cabanelas. The historian recalls that the English cable offices settled in Vigo in May 1873 and the British transferred to the city soon A franchise From the Exiles Club Club, an association where the expatriates could meet, stay with their families, chat about the future of the convulsive start of the twentieth century … and also practice the most popular sports in England and organize teams. Perhaps in Galicia there were still no players accustomed to football, but Vigo already had at that time from a port through which English flag ships with crew willing to play a match against his compatriots of the telegraph. The meetings were played in the Malecon, an area located today in the urban center and that stands out as one of the most sought -after in the city. Conclusion? Cabanelas It is clear: “The first football matches began to be played in Vigo as soon as the English cable arrives in May 1873”. Another chronicle of Vigo lighthouse Of 1880, he confirms that by then the “games with ball” were so popular that they aroused the interest of the neighbors, moving “so many spectators as Rafael Díaz used to have in their equestrian circus.” “The English settled in Vigo in 1873, that is, ten years after the Constitution in England of the Football Association and, from the first moment, their customs were brought … Read more

Australia was discovered in 1606 by Dutch. A theory defends that someone advanced a century: the Galicians

by

Thinking about Australia is thinking about Rare animals with A single objective: kill you. It also implies thinking about the entire country as a British prison. Obviously, it is an exaggeration, but relating Australia with the British is the most normal when it was they who, in 1770 and under the orders of the captain James Cookthey began to colonize the area. But a historian did not believe in official history and developed his own hypothesis: Australia was discovered by the Spaniards. By a Galician ship, specifically, that was brought eucalyptus and left some granaries. 1606, a busy year. The British did not discover Australia, or from afar. The classic Greeks already theorized about something they called “Terra Australis Incognita“Or” unknown land of the south. “They imagined a continent that should be there for the theory of geometric symmetry and even included in European maps without really knowing if there was something there. In 1606, Things changed. The Dutch navigator Willem Janszoon He explored the northern coast of Australia and other explorers from the same country mapped both the north and the west later decades. In 1770, the British Cook arrived at the east coast, explored it and, that same year, he claimed it for the United Kingdom. So He was born The current new South Wales and the English had a new territory to colonize. As? With prisoners that They sent there in 1788. Lost Spaniards. But in 1606 they were not only the Dutch spinning around Australia. Pedro Fernández de Quirós He was a Portuguese explorer in Spain who, in 1605, decided to start from Peru to find that “Incognite Terra Australis.” He reached the current Vanuatu, an island east of Australia, also to the current Tahiti. After weeks, it landed in a larger territory and finally I thought I had given with “Terra Australis.” The christening as “Austrialia of the Holy Spirit” and was so happy. Currently, it’s called Holy Spirit and is part of the Vanuatu archipelago. Quirós and his other ships threw themselves into the sea again, but the ships separated and the captain of one of them, Luis Váez de Torreshe started looking for the main nave. He returned to Holy Spirit, He turned around for the Strait between Australia and New Guinea … and left. The area is named after ‘Strait of Torres‘In his honor and the Australian writer George Colllingridge affirmed that Torres “had discovered Australia without being aware of it.” Robert Langdon. It seems that the Spaniards/Portuguese did not set foot in the continent, but there are those who grabbed a burning nail, defending yes, that the Spaniards had been the first to reach Australia. And if you are thinking that it would be a Spanish historian taking breast, no: it was Robert Langdonan Australian historian who is called the same as the protagonist of ‘The Da Vinci Code‘. Langdon relied on several pillars to develop his theory. The most important was the discovery of guns of Spanish ships discovered in the Atolón de Amanuan atoll of French Polynesia halfway between Australia, New Zealand and South America, in 1929. Langdon defended in his’The lost caravel‘that those cannons were from the San Lesmesa Galician caravel that was shipwrecked in the territory and that pushed its navigators to start exploring the territories of Oceania. They were also reported findings of Spanish armor and helmets in New Zealand that would support this idea, but there are more details that support that idea of ​​the historian. ‘Patakas’ in Australia. A classic construction of Galicia are the Hórreos. It is a peculiar construction to conserve food, such as grain, moving them from soil moisture. They are like high barns that are associated with Galicia, but really in other European countries and even in Japan. This is important because Langdon speculated on the influence of those explorers who departed from Galicia in the architecture and culture of the area. As? With the supposed presence of Galician granaries in the territories of Oceania. The “problem” is that, as there are barns similar to the granaries in other parts of the world, in Polynesia, New Zealand and Australia. They call them ‘Patakas’. Eucalyptus in Galicia. That Galician granario in Oceania would imply the cultural bond between Galicia and Australia, but Langdon also relies on the presence of eucalyptus in Galicia. It is an endemic species of Australia and yes, they took Galicia from the contine In the nineteenth century. In addition, Langdon also used anecdotes to support his belief, such as the presence of indigenous people with light skin and eyes, morphometric aspects in the face that differ from that of the rest of the residents of the Pacific or who knew the metal. The alleged route made by the descendants of the shipwrecked of the San Lesmes No changes in wiki. The arrival of Australian eucalyptus to Galicia is fine Documented And there is no record of transoceanic contacts before the modern era, and that in Australia there are Patakas such as Galicians also implies causality. The result is that there is a lack of evidence that supports Langdon’s theory, and the majority studies carried out by other historians thanks to the period writings show that yes, the Spaniards made several expeditions, but it was Dutch and English who made the greatest advances in the exploration of the continent and its subsequent colonization. Posts to theorize … Now, Langdon was not the only one who threw himself into the pool with alternative theories. Rowan Gavin Paton Menzies He was a British writer and submarine lieutenant who jumped to fame when he affirmed, without providing evidence, that China had arrived in America before Colon. Their Opinions They were embodied in ‘1421: the year in which China discovered the world’. Not happy with it, and also without evidence, he launched the hypothesis that China had arrived 350 years before Cook to Australia and that, in 1434, China sailed to Italy and sowed the spark of the Renaissance.

We knew that the space spheres were at some point in the universe. We have a new theory about its origin

by

The universe is full of spherical objects: stars, planets, black holes and a part of the satellites that we can find in our environment have more or less round shapes. However, there are other types of spheres (or rather other types), spheres that are not formed of compact matter but whose circular nature can be captured by our instruments. Teleios. A few days ago, an international team led by researchers at the Western Sydney University announced The discovery of a unique object spherical located in our own galaxy. Although the main hypothesis about the origin of this object is in the outbreak of an IA type supernova, the team admitted that some pieces did not fit. This leaves the door open to different possibilities. One of the details we know about this object is that it can be detected “almost exclusively” in radio frequencies, something not so conventional in this type of objects. This and other details of the discovery make the object an immense enigma. An enigma that does not even escape its location. The problem of distance. We know that this sphere is found at a not very large distance from our solar system, inside the Milky Way. The problem is that the team responsible for its study has only been able to delimit two possible distances to which the object could be found: either at around 7,175 years-years of us, or about 25,114 light years of our location. This has an obvious involvement and we don’t know what size this sphere is either. If we assume that it is located at the closest point, its size would be about 45.7 light years in diameter. However, it could also be further and be larger: it would be more than 156.6 light years of length if it was found in the farthest location contemplated. Unknown age. The size is in turn a temporary implication. Being an explosion, the object would have formed from inside out, as an expansive wave. That is, if the radius of this explosion is longer, we would be facing a burst occurred longer than if we were watching a shorter radius. The team’s estimates indicate that, if located at the closest point, the supernova that this remnant would have left would have been given less than one millennium; While if it was about the location, we would be talking about an event that occurred more than 10,000 years ago. The problem of X -rays. One of the enigmas that surrounds Teleios has to do with the X -rays or, rather, with the absence of these. The models used by the equipment suggest that the remnants of a supernova as the detected should emit radiation not only in radio frequencies but also in X -rays. IAX type supernovae. The fact that this is not the case has led the team to raise a somewhat different hypothesis: that it is not the remnants of a Ia supernova but of a IAX type. The IAX supernovas are a subtype of the former. The IA Supernovas occur in binary systems dominated by a white dwarf star that absorbs the subject of its companion star until reaching a critical mass that leads it to explode. The explosions of this type of supernovas are very predictable: as they always explode when reaching the same critical conditions, these supernovas shine with a predictable intensity. But not always: There are cases in which the outbreak is lower speed and luminosity. Something that makes these supernovae unique is that they leave behind a important remnanta “zombie star” that we cannot find in conventional supernovae. This hypothesis however poses another problem, and for this to be the case, Teleios would have to be much closer to our planet than the estimates of the team itself posed. As noted, none of the hypotheses raised can answer all the issues raised by this enigmatic object, so more observations will be necessary and determine exactly what we have in front. Askap. The finding of G305.4–2.2, another designation for teleIos, was made in the context of the creation of the evolutionary map of the universe or EMU (Evolutionary Map of the Universe), A work done by the Askap Observatory (Australian Square Kilometre Array Pathfinder). The team recently sent an article to the magazine Publications of the Astronomical Society of Australia detailing the details of the finding. The drafteven under review, it can be consulted through the repository Arxiv. ORCS. In recent years it has been done relatively common Topar with strange circular objects with a certain resemblance to teleIos. Some of these objects are usually classified as a strange circle of radio or orcs (Odd Radio Circles), A name that already accounts for the strangeness they generate in astronomers. These circles usually occur in the Intergalactic space So the scale in which they are given is different from that of Teleios. Initially cataloged as Supernovas, these circles still consider an important enigma for astronomers. In Xataka | We have a new explanation for dark matter.

Huawei plans to advise Nvidia in China. It has a new GPU for theory that in theory is extremely powerful

by

Huawei is putting all the meat on the grill to absorb so much share in the Chinese GPU market for artificial intelligence (AI) as I can. And it is that the entry into force of the last US sanctions package is compromising with all probability Nvidia leadership in China. The US Department of Commerce It has imposed restrictions to the export to the country led by Xi Jinping of The H20 GPUand this in practice means that this chip presumably will not reach the Chinese clients of Nvidia. This last company has announced that this ban will cause a hole in its accounts of 5,500 million dollars Due to the commitments linked to the H20 GPU that had already acquired the reserves of this chip that it will not finally satisfy. Some of the Chinese companies that have bought large amounts from the H20 chip to NVIDIA and who presumably planned to continue doing them are Tencent, Alibaba or Bytedance, but at the current situation they will have to resort to an alternative. And Huawei has put it on a tray. The GPU Ascend 910D aspires to snatch the leadership in performance from Nvidia Huawei reacted immediately to US sanctions. And is that just a few hours after the entry into force of the new regulation of the Department of Commerce He presented his chip for the ascend 920a solution that is clearly destined to occupy in the Chinese market the gaps that the NVIDIA H20 GPU is going to leave. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC. Until now Huawei wanted to get his hardware to dominate the inference processes in AI However, this is not the only asset that Huawei has to increase its market share both in China and beyond its country of origin. And is that, According to Reutersthis company is preparing to start the testing and validation phase of a new GPU for AI: The Ascend 910D chip. Unlike the GPU Ascend 920 that, as we have seen, presumably aspires to compete with the NVIDIA H20 chip, the GPU Ascend 910D seeks to overcome the performance of the chip NVIDIA H100. If this movement is confirmed, already priori this information is reliable, it will be evident that Huawei will have chosen to fight in all hardware market segments for the nvidia. Until now this Chinese company wanted to get its hardware dominate the inference processes in AIand not the training of the models, as Georgios Zacharopoulos, a senior researcher of AI who works on the acceleration of inference in the Huawei laboratory in Zurich (Switzerland) points out in this statement. “The training is important, but it only happens a few times. Huawei focuses mainly on inference, which will ultimately give us access to more customers,” says Zacharopoulos. Inference is broadly the computational process carried out by language models with the purpose of Generate the answers which correspond to the requests they receive. In any case, the information we have reflects that the GPU Ascend 910D will allow Huawei to compete with the chips for the most advanced NVIDIA both in inference and in training.

We have been waiting for years at airports for years. Tiktok’s “airport theory” believes that it has been a mistake

by

If you fly you will frequently be listening to it. The airport must be reached in advance. How much it depends largely on the city from which you take off and what your destination is, but usually the travelers are recommended that they be in the terminal with a margin of 90 minutes either two hours. And that at least. If fate is a distant country, like the US, that margin is quite superior. But … what if that wait could be reduced to 15 minutes? Just listening to it up the pulsations, but in Tiktok there are people (quite) determined to demonstrate the validity of a “Airport Theory” that holds that: that if you have done the Chek-in Online, you don’t have to bill suitcases and the trip is national, 15 minutes is more than enough not to lose flight. Not suitable for cardiac. “Traveling is a pleasure,” as I said Gloria Fuertes. But also a source of stress, nerves and hurry. Especially if you travel by plane. Hence operators Like Aena and the own airlines They advise to present themselves well in advance at airports. The exact time can vary from one case to another, but it usually moves between 90 minutestwo and a half or even the four For some destinations. In Tiktok there are enough people convinced that, at least in certain cases, they arrive with the terminal about 15 minutes before shipping or Even from takeoff. And is so sure of it that has begun to prove it During your own trips. @Michael.dicanzo Can Airport Theory Survive The World’s Busiest Airport ?? 👀✈️🤔 #Airportheory #Atlantaairport #Challenge ♬ Original Sound – Michael Dicostanzo The “Airport Theory”. The trend has been baptized as Airport Theory (“Airport Theory”) and has gained strength especially among Anglo -Saxon passengers. He arrives with searching The hashtag In Tiktok to verify that there is a good handful of videos of people (including Tiktokers with millions of followers) committed to demonstratein their own meats that can occur at the airport with much less in advance of what operators and airlines advise and yet to climb their airplanes without problem. Moreover, the phenomenon has won enough draft to jump from the networks to the generalist media, with reports in US chains and magazines such as The CNN, Fox News either Wired. Some of the videos of Influencers who speak of the theory, like the one who Michael Dicostanzo dedicated him A few days ago, hundreds of thousands of visualizations accumulate. But … What do you propose? Very simple. Roughly, the “airport theory” holds that until now you have been malicanting hours of your life at airports without any need. At least in certain cases. His hypothesis is that if the passenger has already performed the Check-in Online and only loads with hand luggage (so you don’t have to bill suitcases) you can reach the airport 15 minutes before embarking. According to the viral trend that is enough margin to pass the security controls, travel the distance to the boarding row and access the plane. All this, of course, without losing the flight. “Is it really necessary Betsy Grunch wonderswith 2.4 million followers on Tiktok. @itslexismith Testing Airport Theory At Lax ♬ Original Sound – Lexi Smith “I don’t think it’s necessary”. In An interview Recent with the CNN Grunch remembers that she had to check “the airport theory” one day that traffic and luggage problems led him to perform at the HartSfiel-Jackson International Airport, in Atlanta, only 26 minutes before his boarding time. As good TiktokerHe took the phone and recorded what came later: a race not suitable for cardiacs that allowed him to take his flight on time. Other influencer who wanted to verify it was James Shaw, although he opted for An experiment Sater: he went with his wife to a Florida airport with 90 minutes in advance of rigor and then used a stopwatch to calculate how long they took to reach his boarding door. He paused him after 13 minutes. “I think traveling can be very stressful and that’s why we say ‘I need to be there three or four hours earlier, or whatever it is.’ I don’t think it is necessary to do it,” Add Shaw. Of course, he only wore hand luggage and used a service that speeds up the procedures in the terminal. Like Grunch, he also recognizes that they would never test the theory on an international, more expensive trip and in which security controls can be more complicated … and long. The debate, served. Does “airport theory” work? In Tiktok you can find comments and videos both for and against. Also of course pieces of Tiktokers They have ended up seeing how They remain on land. Beyond recordings such as Dicostanzo and the debate that has emerged in networks, there are a few data that help to understand the scope of the trend … and some of its repercussions. A few days ago Wired needed That the “airport theory” accumulates more than 400 million visits in Tiktok, a sudden interest that seems to have coincided with a considerable rebound by Google Trends in the searches of “I have lost my flight, what do I do?” The truth is that airlines usually advise to present themselves at airports with a couple of hours In advance, enough to prevent an unforeseen event, such as a routine luggage control, bottling or tail in access to the terminal, can wait for the trip. “I think it’s nonsense”. Those who seem to be clear are the professionals who work at airports, a priori little supporters that travelers appear 15 minutes before their shipment. The reason: the risks. “The waiting times of security controls can vary from one airport to another, and even from one day to another, within the same terminal,” Explain to the CNN A spokesman for the Dalls/Fort Whorth aerodrome. With a couple of ‘mattress’ hours a traveler can prevent “unforeseen” of the last minute for her … Read more

We have a new “theory of all” to understand Alzheimer’s. Your key is in small granules

by

Creating “theories of all”, unified models that explain various phenomena associated with a scientific field, is not exclusive heritage of physicists. The fight against some diseases can also benefit from models that help us understand their causes and consequences and the processes that mediate. New model. Now a group of researchers has devised a new modela theory that tries to explain Alzheimer’s disease through a “unified explanation of molecular chaos” that derives in this neurodegenerative disorder. According to this new theory, the disease and its symptoms would derive from a collapse of the transport system in charge of moving molecules between the nucleus and cell cytoplasm. This new theory can help simplify a topic as complex as Alzheimer’s. However, its authors remember that this disruption is still extremely complex, with more than a thousand genes involved in it. “Our proposal, focused on the rupture of communication between the nucleus and the cytoplasm leading to massive disruptions in gene expression, offers a plausible framework to understand the mechanisms that lead to this complex disease,” Explain in a press release Paul Coleman, co -author of the new model. A granular problem The model places the formation of chronic stress granules at the beginning of this process. These are clusters of proteins and RNA chains responsible for generating stress in the cell. Stress granules are usually generated temporarily. Its original function is to respond to cell stress by leaving some processes until the cell can recover. Once its duty has fulfilled and the stress disappeared, they dissolve. The problem unleashes when these granules become chronic, which leads them to catch other molecules, making it difficult for them to move between the nucleus and the rest of the cell. From inside out. The model starts from this trigger to explain with it the disease and its consequences outside the cellular unit. And it is that the changes that occur at the cellular level end up affecting cerebral synapses, metabolism, protein processing and cell survival, as explained by the model responsible for the model. The details of the new model were published In an article In the magazine Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association. A disease with many faces. Alzheimer is one of the most intriguing diseases, Explain the responsible team of the new model. In part, they point out, this is because it takes the appearance of various diseases made one, with symptoms that include memory loss and cognitive deterioration, but also changes in personality and in our same internal biology. This complexity, continues to expose the team, is partly responsible for how extremely difficult it is to study this disease. Models like this that schematize their processes, can serve future researchers to find new routes of action that become more effective therapies when facing the symptoms of Alzheimer’s or, even, the same disease.

wants to overthrow Einstein’s special theory of relativity

by

Quarks, the elementary particles that make up the protons and neutrons of the atomic nucleus, are fermions. And electrons, too. There are several types, although physicists like to talk more about ‘flavors’: above (up), below (down), charm (charm), strange (strange), top (top) and background (bottom). The most frequent in ordinary matter are the up and down quarksalthough the one that interests us the most in this article is the top quark for a very interesting reason: it is the heaviest elementary particle that we can find in nature. An interesting note given that we are moving in the field of fermions: supersymmetry is a theoretical model of particle physics that proposes the existence of a hypothetical particle that is paired with each of the fundamental particles that we know. It seeks to explain the existing relationship between the bosonswhich have a spin with an integer value, and fermions, which have a half-integer spin. However, it is important that we do not overlook that it is a hypothetical theoretical framework that, therefore, has not yet been observed in nature. Not even experimentally. CERN has investigated whether the top quark respects the special theory of relativity The quantum mechanics and the special theory of relativity formulated by Albert Einstein constitute the heart of Standard Model of particle physics. Until now, this theory by the popular German physicist has stood the test of time undaunted, but scientists do not miss the slightest opportunity when it comes to putting it in trouble. And it is ideal because it is one of the most effective strategies when what is sought is to go beyond the solid walls of the Standard Model in the hope of develop new physics. Some specific models of string theory propose that at very high energies special relativity will no longer be valid. Lorentz symmetry lies at the very core of this model. Broadly speaking, this property justifies that the experimental results are independent of orientation and speed with which the experiment is carried out in the space-time continuum. It seems like a complicated concept, but if we think about it a little carefully, it is not so complicated. Be that as it may, what is really important is that so far all the experiments that physicists have carried out have supported Lorentz symmetry. However, and here comes the most interesting part, some theories, such as specific models of string theory, propose that at very high energies special relativity will no longer be valid and experimental observations will depend on the orientation of the experiment in space. -time. If so, the Lorentz symmetry would be broken. On paper, it should be possible to identify this break in the energy level that physicists work with in the CMS particle detector from CERN (European Organization for Nuclear Research). For months, CMS experiment researchers have meticulously analyzed the properties of the top quark pairs produced in the collisions at the LHC (Large Hadron Collider). And their result is very interesting: the production rate of top quark pairs remains constant even though the direction of the LHC’s proton beams and the average direction of the top quarks produced in the experiment change depending on the time of day due to the Earth’s spin on its axis. This means that there is no preferred direction in the space-time continuum capable of conditioning the production of top quarks. And, therefore, the Lorentz symmetry is still intact. And the special theory of relativity is still valid.
