15 years later, Instagram arrives at the iPad. He does it with news that make differences to the mobile version

by

Instagram and the iPhone have always gone hand in hand. The first version of the social network landed on Apple’s mobile In October 2010marking the beginning of a relationship that soon became iconic. Android users, meanwhile, They had to wait until April 2012 To be able to join the experience. The iPad, on the other hand, was out of the equation from the beginning. When Instagram reached the market, Apple’s tablet had already been available for half a yearbut never received an application designed for its screen. They have spent almost 15 years without that changing. Until now: This Wednesday the company has finally taken the step. The official Instagram application for iPad is now available Instagram has finally premiered an app designed for iPad, something that many users had time to ask. It is not a simple adaptation: the interface has been rethink for Take advantage of the big screenimproving access to messages and notifications, which can now be seen simultaneously. Even when reproducing Reels Comments can be expanded while watching the video full screen. The change is noticed as soon as the app. Stories are still visible at the top, reels can be seen in a big way and the tab Following It is divided into three views to better organize content: All: recommended publications and reels of all accounts in a row Friends: Accounts that follow the user and those that this also follows The latest: Chronologically ordered publications, prioritizing the most recent The messages also gain prominence: you can consult the entrance tray while a conversation is followed, and the system to read comments in Reels allows you not to lose detail of the video. Instagram has adapted its app to the most advanced functions of iPados. There is support for multitasking and floating windows in Ipados 26 (Available in Beta and that should arrive generally next week), full screen mode both vertically and horizontally and keyboard, trackpad and Apple Pencil compatibility. The application is now available in the App Store for any iPad with ipados 15.1 or higher. If you had the iPhone version installed, just update it: A second app will not appearbut the existing will automatically adopt this new specific design for tablets. Adam Mosseri, head of Instagram, He had admitted That the number of users interested in an app for iPad was never large enough to justify development. That excuse is already part of the past: Instagram finally has an official presence on Apple’s big screens.

If your intuition tells you that “more intense color are richer,” science has good news for you

by

Cardiovascular diseases follow being the main cause of death in the worldbut this scourge can begin to control thanks to the most colorful foods of the supermarket. A new and thorough review study systematic published in Nutrients has put the focus on carotenoidsthe Natural pigments that give their vibrant color to fruits and vegetables such as tomatoes, carrots or spinach. What are exactly carotenoids. Carotenoids are a group of more than 600 compounds that plants, algae and some bacteria produce naturally. They are responsible for the red, orange and yellow tones of many foods. Among the best known we can highlight the lycopene that is very present the tomatoes, the beta-carotene that is in carrots (and can get to give us an orange color on the skin) and the Lutein o Zeaxantine that are in green foods. Components of great importance for humans. Humans cannot produce these carotenoids, as with some vitaminsso we depend on the diet to obtain them. But his fame is not free: they act as Powerful antioxidantsneutralizing the free radicals they produce Oxidative stress and ends up damaging the cells and the genetic material itself. In addition, the study highlights its anti -inflammatory properties or its ability to improve the cholesterol profile by reducing oxidation of ‘bad’ or LDL cholesterol. This is something very relevant, then The oxidation of LDL is the trigger to form the atheroma plates In blood vessels, which is a key risk factor for Atherosclerosis. That is, the hardening and obstruction of the main arteries of the organism that can finally cause a heart attack. Evidence on the table: real food vs. supplements. The researchers, led by a team from the European University of the Atlantic in Santander, analyzed 38 of the most relevant studies published in the last decade to answer a key question: does the carotenoid intake prevents cardiovascular diseases? But beyond this, they also wondered if The supplements that can be found work or a varied diet is better. Having them in blood is associated with a healthier heart. The observational studies of cohorts that followed large groups of people for years, are quite consistent: those who had higher concentrations of serum carotenoids presented, in general, a lower risk of cardiovascular disease. Specifically, there was an inverse correlation with hypertension, the rigidity of the arteries and several inflammation markers. This suggests that a usual consumption of rich foods in these compounds is a good cardiovascular health indicator. Do carotene supplements work? This is where the thing is complicated. The studies that gave the participants carotenoid capsules showed results that were often contradictory. On the one hand, when the lycopene was given in supplement, he recorded an improvement in the endothelial function of patients who already had cardiovascular disease, but not in healthy volunteers. In the case of lutein, a triglyceridesand with beta -carotene the significant effect was null. This is something that surprised the researchers, but even more they were amazed to see that by providing several carotenoids together the effect was more effective than with the use of an isolated carotene. This already gives us an important clue. Real food wins the game. The clearest verdict came from dietary intervention studies. When participants were provided with foods such as tomato or carrot juices, or they were indicated to increase the consumption of fruits and vegetables in the diet, the benefits were more notable and consistent than with the pills. Interventions with tomato juice in lycopene managed to reduce key inflammatory molecules in atherosclerosis, while increasing the consumption of fruits and vegetables improved antioxidant capacity of “good” or HDL cholesterol. In this way, scientific evidence suggests that carotenoids have to be consumed in ‘groups’ to have a greater effect. The conclusion is clear: we must not replace the vegetable. On many occasions we try to supplement what we do not like with herbalist treatments. This is not ideal in this case, since the cardioprotective effect of the carotenoid seems to be amplified with other compounds that the original food such as fiber or vitamins presents. But it also adds to the need to complement it with other fruits and vegetables. And you don’t have to become obsessed with tomato and carrot in this regard. There are a lot of fruits and vegetables that can be included in the diet in a varied way so as not to end ‘hating it: peppers, pumpkin, broccoli or kale are some of the examples we find. Time is vital for your protection. As in medicine, the effects are not usually immediate when a change in the habits of a patient is made. In this case, long -term observational studies show the strongest results, that is, It is the sustained habit of consuming these foods What really protects the heart. A good diet is fundamental. This conclusion is no secret to us, since there are many studies that point to important benefits of following a good diet. For example, the Mediterranean diet It can help us stop the aging of the brain. Although it is also a reality that there are many diets such as potato diet either Miracle diets In general, they are a pathology to face it in the absence of nutrients or a subsequent rebound effect.

Intel has gone from mastering the world to being a forced partner of the United States. They are bad news for Europe

by

Intel has just sold 10% of your company to the United States government for 8,900 million dollars. The operation confirms what many suspected: the most iconic chips manufacturer in the world can no longer survive without state help. The panoramic. For three decades, the ‘Intel Inside’ stickers glued to millions of computers symbolized US domain in semiconductors. Intel and Microsoft created The era “wintel” that defined personal computing. In 2009, the Obama administration even presented antitrust charges against Intel for its dominant position. Today, the company is worth 108,000 million dollars while Nvidia, its former subordinated, reaches 4.3 billion. What has happened. Last Friday, Donald Trump announced that the United States acquired 10% Intel in exchange for promised funds under the CHIPS ACT They never arrived. It is not technically a rescue, but it looks a lot. Trump sold it as a big business: “I paid zero for Intel, it is worth approximately 11,000 million dollars” (capital letters are yours). The reality is more complex: Intel had been waiting for those 8.9 billion already committed by the previous administration for months. The company desperately needed money: Its foundry division lost $ 13.4 billion last year. He has fired between 8,000 and 10,900 workers. And the most worrying: not even Intel’s own product teams want to use their factories, preferring that TSMC manufactures their chips. Why is it important. This operation marks a turning point on three critical fronts: For Intel, It means losing business autonomy. 76% of their income comes from abroad, with China representing 29%. Now each decision will be under the political scrutiny of his government. As the company itself warns in regulatory documentsthis could “cause adverse reactions of investors, employees, clients, suppliers, foreign or competitors.” For the United Statesrepresents the return of state capitalism in technology. It is the first direct government intervention in a company from the rescue of the 2008 automobile industry. Trump has already suggested that there will be more: “I will make agreements like this for our country constantly.” For Europethis is especially worrying. The European Union partially depends on Intel for its ambitions of technological sovereignty in semiconductors. If the largest Western chips becomes an instrument of American industrial policy, Europe is in an even more vulnerable position against Asia. The Trump government has already asked TSMC to help rescue Intel factories. Also He took a “golden action” in Nippon Steel and Plan to stay with part of the sales that Nvidia and AMD make to China. The message is clear: the semiconductor industry is now a national security issue. Between the lines. Intel’s fundamental problem is not solved with public money: Intel failed in smartphones when he rejected to make chips for the first iPhone. He was late to AI while Nvidia was ahead. And he lost his leadership in manufacturing against TSMC, which not only has better technology but A superior business model As a pure foundry. As pointed out Intel’s CEO himself, Lip-bu Tan, “twenty or thirty years ago we were leaders. Now the world has changed. We are not among the ten main semiconductor companies.” Its survival depends on the success of the 18A manufacturing nodehis latest technological commitment. And now what. Intel is now a company supported by the State, something that its own managers warned could scare customers. Meanwhile, Trump promises more similar agreementseven suggesting the creation of an American sovereign fund with participations in technology companies. For competitors, this creates a scenario of unfair competition: AMD, Qualcomm and other companies now compete against a rival that has the US government as the main shareholder, with all that that implies in terms of government contracts and political decisions. Senator Rand Paul He summarized it With irony: “If socialism is the Government possessing the means of production, wouldn’t the government be having part of Intel a step towards socialism?” Paradoxically, Bernie Sanders, a declared socialist, applauded the measure. Intel went from being the symbol of American technological capitalism to become his first large semi-nationalized company of the 21st century. For Europe, which struggles not to be behind the technological career, it is an alarm signal: the era of the free market in semiconductors is over.

So much ice has melted in Greenland that the plankton has grown 40%. It is not good news

by

The Antarctica and Greenland have become two of the Climate change thermometers. The Ice loss in Greenland It is something that has been monitored for years because not only influences sea level: also in the Sinking of the seabed. It is estimated that Greenland’s glaciers have reached a point of no returnand its implications go beyond sea level. In fact, a recent NASA study He points out that there is a beneficiary of the thaw: the phytoplankton. And it is not good news. Short. A few months ago we commented that Greenland was getting greener. The estimates point out that, during the last 30 years, the region has lost 1.6% of its ice, which may seem little, but it is something equivalent to the Galicia area. The air temperature is about 3 higher Celsius degrees in the period between 2007-2012 than in 1979-2000, and That thaw It is causing a huge increase in fresh water. How much? According to the investigation of San José State University and NASA, of up to 266 million tons per year that are discharged into the sea, especially under the Jakobshavn glacier, the greatest in Greenland. It is the equivalent of 1,200 cubic meters of fresh water that are poured into the sea every second. As is fresh water, it is less dense and lighter than the salty, and what it does is like a whirlpool, dragging nutrients from the seabed to the surface. The study. These nutrients are mainly iron and nitrates, and it is phenomenal to phytoplankton. It is, however, an anomaly, and the researchers wondered to what extent that rapid growth of the plankton could affect the ecosystem. In it studypublished in Nature, detail how with the help of a model developed in the JPL and the MIT and using superoringers to accelerate the calculations, simulated the interaction between the water of the thaw, the nutrients and the phytoplankton. The greatest areas is where an increase in chlorophyll has been seen in recent years They have discovered that the growth of the body in the studied area increases between 15% and 40% in summer, at which time the maximum point of the thaw is given, thanks to those nutrients that the fresh water current sends to the surface. In total, NASA has observed That, between 1998 and 2018, the growth of phytoplankton in argic waters had increased by 57%. Consequences. On the one hand, that increase in phytoplankton can be positive for marine life, since it improves the basis of the ecosystem to be able to feed more animals, and also phytoplankton Atmospheric co -capture (that is not bad for us) To do photosynthesis. However, there is a paste: changes in temperature, chemical composition and water salinity can alter ecosystems. In the study they have not launched predictions about what will happen, but it is evident that it is a substantial modification of the marine properties of that specific area. Its conclusion is that those Changes in the Food Chain They can modify the composition of marine species, from bacteria to fish, affecting both the equilibrium of the ecosystem and fishing activities, which are a key engine for Greenland. Because phytoplankton is tiny, but it is the food of Kril and other small herbivores that, in turn, are the larger animal food baselike fish and whales. Only in Greenland? This study was carried out in a very specific area, that of the Jakobshavn glacier, but the results have similar implications for the more than 250 marine glaciers in the region and, possibly, for other glaciers that end in the sea in other regions of the world. Researchers comment that this simulation method is adaptable to other systems and that, therefore, it is likely that other areas where glaciers are pouring water into the sea They are also living, to a greater or lesser degree, a similar phenomenon, modifying ecosystems and affecting both fauna and fishing activities that are carried out in the area. Therefore, the thaw of glaciers is no longer that it affects only at sea level, but has the potential for alter the ecological balance of the regions in which it occurs. As they say, we were few and the grandmother gave birth. Images | POT In Xataka | 400,000 years ago all Greenland ice melted. The map he drew is not flattering

We have asked Renfe what alternatives we have to the cancellations of the AVE in Galicia. There are good and bad news

by

For sixth consecutive day, the high -speed circulation of the Galician corridor remains suspended. The service between Madrid and the Galician cities is provided only partially and in extraordinary frequencies. We have spoken with Renfe and consumer associations to know what their alternatives are. Sixth day without bird. Renfe cannot provide the high speed service of the Galician corridor as a whole. So The company itself confirmed it on its social networks but On its website Information about the latest news related to the railway situation between Madrid and Galicia is not found. No, at least, with a first glance. It is the result of the serious fires that are ravaging Zamora, León and Ourense, which They do not allow for sure to the high speed line. Given the impossibility of guaranteeing an improvement in them and, therefore, an opening of the line, Renfe confirmed almost at 11:00 am that all trains of today Tuesday, August 19, were suspended. Click on the image to go to the original tweet To (or from) Zamora. The solution that Renfe is giving is that passengers who prefer can travel from Madrid to Zamora or start their trip to the capital in the latter city, if it moves in the opposite direction. It is a patch that also requires adapting to Special schedules because the usual frequencies or schedules are not being fulfilled. Arriving in Galicia from Zamora or arriving in Zamora from the Galician community has already been in charge of the client. The latter is the one who has to look for life to take the train or reach its original destination. Something that, from Facua, they point out, should not happen. Buses? Jordi Castilla, Facua spokesman, explains that Renfe has the obligation to allow the change of ticket or its cancellation for free. Something that is already doing. However, it specifies that the company has to “relocate the person in an alternative environment without any cost.” From Xataka We have asked Renfe about this possibility and if they are valuing to include it in the next few days but we have not obtained an answer. Nor have those who In social networks they are asking Link Galicia with Zamora by bus since the main roads remains open. From Facua they emphasize that if the suspend and Renfe service does not offer this possibility, the client has the right to use a public transport means (such as a bus) and claim the money from the company. Not so a private transport, so the airplanes would be discarded. Cancellation expenses could also be claimed, such as a hotel night. What if I want to travel to or from Zamora? In Xataka We have contacted Renfe’s customer service. From Facua they point out that if we have a ticket with departure in Madrid to a Galician city and cover the journey to Zamora (or we start it in this city to Madrid) we have the right to receive part of the previously paid ticket. The same has been confirmed to us from the customer service of the railway company but, unlike the change of tickets or its cancellation, it cannot be done by telephone. In this case, you have to perform a online claim by filling out the form which is facilitated on the web or attending the office of the origin or destination station. Little in advance. Until now, Renfe has preferred to hurry until the last moment the cancellation of the trains. To the point that the confirmation that no train would circulate today in the high -speed line has not reached almost noon. That is causing many users to ask the company through social networks like Twitter what will happen to their tickets. The answer is repeated in that case: the client will be informed by social networks, mail and SMS. The telephone service and the website are being referred to change or cancel the tickets but in X only reference is being made to the confirmed cancellations and not to the trains that, it is not confirmed, if they will circulate in the next few days. What if I travel the weekend? In Xataka We have asked Renfe’s customer service if possible change or cancel a ticket for next Friday. They have confirmed that yes, there would be no problem even without the company having not yet confirmed the cancellation. From Facua they explain that in this, and in any other case, there is no minimum anticipation time with which Renfe or any other company must operate. “It remains in the good or bad faith of the company because if you know that it will be impossible to travel, you should inform you as soon as possible so you can look for alternatives and not have to adapt at the last minute.” Despite this, we can confirm that by telephone, these returns are being admitted even though there are still no confirmed cancellations beyond today, August 19.

Tesla’s collapse in Europe brings bad news for Spain. Specifically, for Valencia

by

The Tesla gigafactoría project in Valencia has entered indefinite hibernation. From the memorandum signed with the Generalitat In June 2023there have been no tangible advances: neither public contracts, nor works of works, nor investment of investment. Tesla I had found ideal land in Chesteand the Consell – at that moment, of Ximo Puig – had promised express processing as a strategic territorial project, the same formula that has worked with Volkswagen in Sagunto. But there has been everything. Why is it important. Tesla’s paralysis leaves the Valencian Community with an industrial promise less and the urgency of not mortgaging public resources in ghost projects. Ford Almussafes is going through its worst crisis With you are and fall in production. The region needs real investments, not memoranda of understanding that do not reach anything. The case also shows the risk of the “announcement effects”: Land price inflation. Frustrated job expectations. Administrative resources dedicated to processing castles in the air. Valencia must learn from Sagunto: industrial projects are measured in signed contracts and verifiable calendars, not in preliminary meetings. The context. Tesla has gone from leading the continental electric market to An unprecedented sales crisis. In Germany, the first European market, it has barely sold 1,110 units in July – a 55%drop – while the electricity sector grew by 58%. The company has descended from the first to the fourteenth place among the best -selling brands in German territory. None of its models are among the most popular twenties in the country where it has its only European gigafactoría, which is also the most populous in the continent and one of the largest in purchasing power. In figures. Tesla numbers in Europe draw a generalized collapse: United Kingdom: -60% (987 units compared to 2,462 of the previous year). Sweden: -86%. Belgium: -58%. France: -27% monthly, -40% accumulated annual. European market share: 1.8% to 1%. The contrast. While Tesla sinksVolkswagen has doubled its electrical sales in 2025 and dominates the continental market. He ID.3 leads German sales with 2,907 units, followed by ID.7 with 2,675. Half of the electric sold in Germany already carry the VW logo. The gigafactoría of the German group in Sagunto advances as planned: work, signed energy agreements, production scheduled for 2026 and thousands of guaranteed jobs. A real project against an evaporated promise. Between bambalins. The Berlin factory has reduced the production shifts of the Model and three to two newspapers. Los Tesla not sold They accumulate in an old East German airport60 kilometers from the plant, waiting for buyers that do not arrive. The cheap model of 25,000 euros that Tesla planned to manufacture in Valencia is also frozen. The company now bets on a decaffeinated version of the Model and: same car but with fewer qualities, without glazed roof or rear screens. In summary. Tesla has gone from revolutionizing the electricity market to become a more brand among many, and not the best positioned. His ghost gigafactoría in Valencia is the perfect symbol of this fall: a project that was born as a promise of the future and has been reduced to a archived memorandum. While Volkswagen does build in Sagunto, Tesla stacks without selling cars in abandoned airports. The lesson for Valencia is clear: in industrial policy, the only jobs they count are those that have payroll, not those that appear in PowerPoints.

The remake of ‘Hold it as you can’ has worked very well at the box office. Excellent news for an almost dead genre: comedy

by

The new version of ‘Hold it as you can are not exactly a rarity: in a cinematographic panorama absolutely full of sequelae and remakesa new version of a 1988 classic is not a precisely revolutionary decision. Something more surprising sounds, however, that we are talking about REBOOT of a mythical comedy, which returns to the gender to the rooms through the big door. AGARRATE IT 2025. We all know ‘hold it as you can’: A trilogy of police comedies that the Zaz trio rolled after ‘lands as you can’, and that made Leslie Nielsen late and throbbing star of the surreal chufla. His success unleashed all kinds of imitations, some more fortunate than others (and in Spain, many of them with the “… as you can” by the title), and now enjoy a new installment with Lian Neeson and Pamela Anderson. And all respecting the original canon: destroying parody of the thriller codes, and prominence of a star not known for its comic roles and that puts an unexpected and devastating vision on the table. Well, it has worked. It has not become the number one of the box office (it was possibly either its intention, it remains behind ‘The fantastic 4’ and ‘bad types 2’), but he has had a great start in the United States: 17 million dollars, plus 11.5 million in the countries where it has premiered (Spain does not reach August 22). A budget of 42 million is estimated, so it is an excellent starting point, in a film that can grow and stay in the rooms if your mouth works. And there are reasons to believe that mouth mouth could be activated, because also against any forecast, the film is collecting very good opinions: an a- In Cinemascore and a 90% in Rotten Tomatoes They corroborate it. Long live comedy. This box office triumph is more than a punctual success: it is a success for a genre that had not enjoyed something like that for many years. In fact, Neeson himself ironized about it in An ad that has been seen as the promotion of the filmand in which he claimed different comedies (all from Paramount, producer of this new version): ‘The reporter’, ‘Out of wave’, ‘Hot Rod’, ‘Superdetective in Hollywood’, ‘Rock School’, ‘The Truman Show’, ‘Zoolander’ and others. The web Savecomedy.org Refer to the web where you can buy tickets for the new ‘hold it as you can’. Comedy is a serious thing. Although the video is a joke, the question is very serious. Because the study comedy, with great stars, has not died at all. But Yes has done it in the rooms: Being a genre where the show is not the priority, to a large extent it has been relegated to streaming, or shyly enters combination with other genres to Abrise step towards the rooms. ‘Lilo and Stitch‘It’s family cinema,’ Novocaina ‘is action cinema,’Mickey 17‘, science fiction, and’A Minecraft movie‘, an adventure fantasy. Except for some other very punctual example, such as ‘Bridget Jones: crazy with him’ or ‘somewhat pregnant’, which do not stand out especially at the box office, the case of ‘holding it out as you can’, a pure and adulteration comedy, it is a rarity. Much more that is successful. There are no stars. It is a pity that actors that we previously identified with comedy, such as Will Ferrell, Melissa McCarthy or Adam Sandler have been recycling or directly disappearing from the map (or, in the case of Sandler, taking refuge in the streamingwhere he obtains very juicy dividends). Will we see a resurgence of those times in which ‘Porky’s’ (in the eighties), ‘American Pie’ (in the nineties) or ‘Virgin at forty’ (in the two thousandsses) they generated trends, made authors and distribute emerged and unleashed a wave of copies? Hold it as you can get it in his day, Maybe your reboot can work again. Header | Paramount In Xataka | The figures suggest that the domain of blockbusters in Hollywood is not over.

The good news is that there is a material that works well on the walls of fusion reactors. The bad: it is lithium

by

We know how the sun works. Another thing is to imitate it. If we got Build a nuclear fusion reactorwe would have clean, safe and practically unlimited energy. But doing so involves incredibly complex engineering challenges. The wall problem. One of the more colossal challenges In nuclear fusion is to build a container that supports a hottest plasma than the sun’s core. For years, scientists have been experiencing with various materials, from graphite to high resistance metals such as tungsten. A recent researchthe result of an international collaboration of nine institutions, confirms that we have a star candidate that works spectacularly well for the wall of the reactors: lithium. A self -refrasinal shield. To understand why lithium is so attractive, you must first visualize the hell that is unleashed inside a tokamak, the most common fusion reactor design. A hydrogen gas, mainly its deuterium and tritium isotopesmore than 100 million degrees Celsius is heated to become a plasma. Magnetic fields potently confine it so that it does not touch anything, but it is impossible to prevent some particles from escaping and violently shocking against the interior walls of the reactor. This is where lithium shines because it can be used in a liquid state. Instead of eroding and degrading with each impact, it flows and heals himself instantly. This self -referential liquid layer would protect the solid components behind. Moreover, if the reactor walls are hot enough, the lithium can form a steam shield that absorbs much of the impact before it reaches the solid surface. Goodbye to graphite? Research shows that lithium is not only a passive shield, but an active plasma conditioner. Instead of reflecting the fuel particles that escape, cooling the edge of plasma and destabilizing it, lithium absorbs them. This helps keep heat where it has to be and, therefore, to stabilize the fusion reaction and improve the confinement of plasma. According to researchers, lithium is a promising candidate to replace graphite, which has a much higher erosion rate. Applied in tungsten walls, it allows to operate the fusion to greater power densities, opening the door to more compact and efficient reactors. Two ways to apply it. The researchers tested, on the one hand, to cover the lithium walls before lighting the plasma and, on the other, to inject lithium powder directly on the plasma during the reactor operation. The injection was much more effective when creating a uniform and stable temperature profile, one of the sacred conditions for commercial fusion. All tests were carried out at the Tokamak Diii-D of General Atomics with financing from the United States Department of Energy. The authors of the study, published in the Materials and Energy nuclear magazine, are researchers of the Princeton plasma physics laboratory and his collaborators. Bad news. In addition to exercising even more pressure on the already tensioning lithium market (Although it does not scarce, it is not extracted to the rhythm that grows its demand), there is a more alarming problem. The lithium is too much Well at work. Catch the tritium with a very high efficiency, preventing it from returning to plasma to be used as fuel. If the tritio is stuck to the walls, the reactor ends up running out of fuel and the cycle breaks. The accumulation of radioactive tritium in cold areas and difficult to access the reactor also greatly complicates its maintenance and is a safety risk. To top it off, the retention is more significant if the lithium is injected with the reactor in operation, the most efficient application method. A possible solution. The key is that these experiments were carried out with lithium in solid state, at temperatures below its melting point. In a real reactor, with liquid lithium, The solution could be a “dialysis” system: Instead of bathing the walls by a lithium river and leaving it there, it would be continuously extracted from the reactor, taken to a processing plant to separate the tritium trapped, and pumped back, clean and ready to continue working. The reactor design would have to adapt to this new proposal. It would be necessary to avoid the cold areas where lithium and tritio could accumulate and stay stagnant, keep the walls at higher and more controlled temperatures, and include the circuit to extract, processes and continuously introduce lithium. A material that solves multiple problems in our mission of simulating the sun, but in return introduces new and also complex.

There is studies that ensure that more than 50% of the couples who give the ‘yes I want’ in Spain end up separating, but New research American has just delved into that data with a curious revelation: today it is much more rare than a newly married couple to separate after ten years of conjugal life than those that joined 50 or 60 years ago. The big question is … why? Condemned to divorce? Recently he Institute for Family Studies (IFS), an American institution that is dedicated among other things to conduct studies on families and marriage, it was done An interesting question: Is the old mantra true that half of the marriages end up in court signing their divorce? It is not a minor issue. First, because at least in the US it looks like a popular mantra. Second, because that bulky percentage equals the chances of succeeding in conjugal life with those of launching a currency and that is expensive. What did you discover? For his investigation, the IFS took advantage of the data of the US Census Officeso his conclusions are basically a relay of what happens on the other side of the Atlantic. Making clear that starting point, it is not unreasonable to think that the patterns and trends that it has identified are more or less transferable to Europe. The reason? His experts discovered a very clear phenomenon: although it is true that every time We get less marriedcouples who give the ‘yes I want’ today create unions much more solid than those of a few decades, when there were many more people who formalize their relationship.

It is a percentage somewhat higher than that of the couples who married in the 1950s, but it is below those who gave the ‘yes I want’ in the 60, 70, 80 and 90. Ifl has not published their data in detail, but it has prepared a revealing graph that shows that the percentage of marriages of the 1970s dissolved after ten years was around 30%. Moreover, according to their data it is not correct that half of the marriages end up breaking. Taking into account its most recent records, that percentage Round 40%. And his forecast is that he descends as time passes. What does that mean? “The new marriages are more solid today than in any other decade since the 50s. Although the new marriages in the 2000 collect the report. “We have verified an increase in stability since the late 1970s. And so far the marriages formed in the 2010 maintains.” Are there more readings? After accounting the IFL discovered that the percentage of dissolved marriages after ten years of relationship varied considerably depending on when the couples had married. Among those who did in the 50s represented 14%, among those of the 60s 18%, in the case of married couples in the 70s the divorce percentage reached 30%and those of the 80s, 27%. Since then that indicator has decreased to 18%. If we talk about the risk of rupture, among the official marriages in the decade of 2000 the culminating point is five years of relationship. From that moment the risk is slowly decreasing. In the case of marriages created in the 70s the “high point of instability” occurs at age eight. What about gray divorce? The IFL points out that curiously what seems to gain relevance is the “Gray Divorce”the one that occurs between couples over 50 years after decades of relationship. It is nothing new, nor exclusive to the US. In 2022 the INE scored 80,000 divorces In Spain, of which 33% occurred between marriages that had more than two decades together. The IFL however recalls that most married people over 60 years of age went through the altar in the 70s and 80s. Click on the image to go to Tweet. What does all that mean? That the resistance of marriages seems to have evolved with society itself. The percentage of divorces was low in the 50s, increased after “the cultural transformation of the 1960s and 1970s radically changed the stability of the unions” and has been reconfigured as couples did, less and less prone to marry. “The most recent marriages have already shown greater stability, which could be due to the fact that they are more selective,” the study slides. They are valuations in the light of US data, but Spain has experienced its own drift. In our country a milestone was marked by the approval of the Divorce law In 1981. Have couples changed? Yes. And that is something that The study American also reflects clearly. If in the 1980s 80% of the people married before they turn 30, between 2000 and 2012 that percentage had declined to 64%. The trend is transferable to our country. Last year the CEU demographic observatory published A report It shows that the probability of ceasing to be single before the age of 50 has gone from representing almost 100% to move between 43 and 47%, depending on whether we talk about men or women. Do we get married later? Yeah. The analysis CEU also confirms that in the 70s between 85 and 90% of the people who married they did it before 30 years. Today that percentage does not even reach 20%. In 1976 the Spaniards who were married for the first time had average 26.7 years (24.1 if we talk about women). In 2022 the figure was already 36.8, or 34.9 in the case of brides. The report, however, reaches a different conclusion from that of the IFS on divorces: according to their accounts, 50% of the unions end up in rupture, … Read more
