22 hours straight non-stop

Airbus has taken off for the first time the A350-1000ULR, an ultra-long-range variant designed so that commercial aircraft can cross the planet without a single stopover. The premiere took place a few days ago in Toulouse (France), where the aircraft flew three hours and 43 minutes and exceeded 41,000 feet in altitude, about 12,500 meters. We tell you everything in detail. The plane. The A350-1000ULR is, in essence, an A350-1000 to which An extra fuel tank has been added at the rear of the fuselage. This change in its structure gives it around 1,000 nautical miles more autonomy than the standard version, that is, about 1,850 additional kilometers. With this it aims to become, once in service, the commercial aircraft with the longest range in the world, surpassing the A350-900ULR. What was it created for?. Behind is the ambitious Project Sunrise of the Australian airline Qantas, which seeks to directly link Sydney with cities such as London or New York. The Sydney-London route exceeds 18,000 kilometers and until now required making at least one stop along the way. According to the company itselfthis aircraft will allow “direct flights between two continents that have never before been connected without stopovers.” The 22 hour challenge. The A350-1000ULR is designed to endure journeys of up to 22 hours uninterrupted, and that changes certain priorities from an engineering point of view, since the range alone is not enough, it is also important that the cabin is bearable for almost an entire day. That is why the certification will analyze ventilation, temperature control and a new cooling system for the onboard kitchens, lighter and more efficient. On a plane like this, every kilo counts for consumption. The cabin will also have a special configuration with a space where passengers can stretch their legs. What happens now. The inaugural flight opens the season for an entire test campaign of about two months aimed at certifying all the modifications. The device that has flown, identified as MSN 707carries specific test instrumentation and will later be reconditioned to have all Qantas commercial configurations. Curiously, it will not be the first to arrive at the airline, since the second device is in an advanced assembly phase and, since it is not carrying the test equipment, will be delivered soonerscheduled for April 2027 and a four-class cabin. Figures for an ambitious project. Qantas has ordered 12 units of this version for Project Sunrise, in addition to another 12 standard A350-1000s to reinforce its international network. The model is the fourth passenger variant of the A350 family which, according to Airbus data, had accumulated some 1,579 orders from 68 customers and more than 700 aircraft operating on long-haul routes at the end of April of this year. The range will soon grow with the A350Fthe upload version that is still in development.

the graph that proves that Europe plays something else

Today the rich are richer than ever and there are more of them than ever in the history of humanity. However, their distribution throughout the planet is very different from how they did a decade ago because, quite simply, there are countries where the ultra-rich grow more. Only in this last five years, 162,191 new ultra-rich “appeared”, that is, 89 people crossing the economic threshold of 30 million dollars a day (the barrier of high net worth individuals, or HNWI for short). Understanding where money is concentrated is the first step in anticipating investments, influences and geopolitical tensions. The club of the very rich. The graph you see below these lines has been prepared by Visual Capitalist and orders the states of the world according to two parameters: how many new ultra-rich people gain and how fast that club of very rich people grows. Combining the two makes sense: a high number may not be that high in a broad-based country like the United States, and a high percentage increase implies that something new is making people rich there. The data comes from the real estate consultancy and wealth manager Knight Frank through its report “The Wealth Report 2026“, which uses its own economic growth model including variables such as GDP growth, inflation, interest rates or the behavior of financial markets. Where there are more and more rich people. Visual Capitalist Why is it important. In a sentence: because money calls money. Where the ultra-rich live, capital also comes: buyers of luxury properties, investors in startups, investment funds, demand for high-level services… On the other hand, these people who concentrate wealth are also the subject of regulations in order to reduce economic and fiscal inequalities in a kind of tug-of-war of attracting and retaining capital in the face of economic imbalances in welfare economies. The United States is a factory of the rich: It is home to almost 40% of all the world’s rich people with more than 10 million dollars, almost double that of China (second). In the segment of 100 million or more, it also exceeds 40% of the world total. The explanation for this accumulation of wealth lies in a mix of a highly developed stock market, low tax pressure on capital, a mature and solid entrepreneurial ecosystem, and a legal system that firmly protects private property. Between 2021 and 2026, the US has added almost 67,000 new ultra-rich people, triple that of China. It is the largest manufacturer of great fortunes on the planet, notably compared to the second. That economic phenomenon called India. India is the most interesting case on the entire list because it combines speed and scale. In the last five years, its population of ultra-rich grew by 63.4% thanks to technological entrepreneurship, the digitalization of the economy and the development of its capital markets. It is not inherited or extractive wealth: it is wealth created by entrepreneurs and companies. Thus, the Asian giant has already taken bronze after the United States and China and is imposing a ferocious pace: India already has 207 billionaires and by 2031 the projection points to 313, 51% more. It is, in short, the only country that simultaneously appears in the top positions in both percentage growth and absolute volume of new great fortunes, thus becoming the economy with the greatest potential for private wealth creation in the next two decades. Europe is on another roll. Europe grows piano piano and not without internal tensions. Germany, Switzerland and France occupy third, fifth and seventh place respectively in terms of increase in ultra-rich people, but if we look at the speed of growth, they almost disappear from the ranking in favor of unexpected ones like Romania or Greece. The problem is not so much the numbers but the fiscal pressure, and stricter regulation where private property collides head-on with the welfare state. However, within the continent itself there are tremendously unequal policies, from the Swiss tax haven to France and your plan to tax the richest. Those covered: Poland, Qatar, Indonesia and Vietnam. Just a decade ago these countries did not appear in any pool of private wealth, but there is Poland as the outstanding leader in percentage growth of ultra-rich people between 2021 and 2026 with 109.2%, which has meant going from 1,442 to 3,017 individuals. Qatar follows with an increase of 106.9% and then Türkiye, with 93.6%. It is, in any case, double or triple the average. Of course, there is an essential nuance: they start from very small bases, hence in absolute terms they are still small groups compared to Germany or France. In the next five years the ranking is completed with other emerging countries: Indonesia leads the projections with an expected growth of 82%, followed by Saudi Arabia and Poland with 63% each. Just behind, Vietnam with 59%. What do they all have in common? Improve the scenario for private capital: more legal certainty, accelerated industrialization and in the case of Middle Eastern countries, almost zero taxation accompanied by residency programs for large assets.

is that we are not interested in the least

The United States struck first. Europe’s response was to negotiate. That was the first reaction of the European Union to the 25% tariffs imposed by Donald Trump’s Government on cars, the parts that make them up, steel and aluminum. Also to the 20% tariff in flat rate format that the United States imposed on all European Union countries in April 2025 when a trade war broke out that is still ongoing. Faced with the American attack, the first thing the European Union did was negotiate. Logical if we take into account that Europe is risking the future of many sectors, but the automobile is especially critical. According to UGTOn average in Europe, 3.2% of employees in each country work in the production of vehicles and engines or in activities associated with them such as repair or distribution and sales. The document mentions the Draghi Reportthe result of a study commissioned by the European Union from the former president of the European Central Bank to seek solutions to the European economic decline in the face of emerging powers. It noted that in Europe there are 13.8 million people working in the automobile sector, representing 6.1% of the active population. According to the European CommissionIn 2025, vehicles worth 38.9 billion euros were exported to the United States. Only the United Kingdom, which bought cars worth 34.3 billion euros, rivals this country. To this we must add that many European vehicle manufacturers produce in Mexico or Canada as bridges to cheaper entry into the United States. The result was immediate. The Group Volkswagen stopped its deliveries in the United States and its shipments by rail from Mexico. Mercedes considered reduce your offereliminating the smallest models that report the lowest profit margin. BMW chose to absorb the tariffs softening the blow as best as possible. And Stellantis sent home to workers inside and outside the United States to produce fewer cars. Finally, an agreement was reached whereby European cars would pay 15% in the United States while a red carpet was laid out in the opposite direction. It wasn’t coincidence. An impossible response proposal As we say, in search of a solution, the European Union put on the table a non-existent tariff for cars arriving from the United States. In The World they collected the words of Ursula von der Leyenpresident of the European Commission, recalling that this same proposal had already been put on the table two months before. However, the European Commission stressed that they did not receive an adequate response then. And the same thing ended up happening two months later. In April 2025, Donald Trump went before the cameras to threaten China with raising tariffs even further and to indicate that he is not convinced by the European proposal. For the president of the United States, it was not enough. “The EU has been very tough over the years. I always say that it was formed to hurt the United States in trade. That is the reason why it was formed (…) They came together to create a monopoly situation, to create a unified force against the United States in trade. (…) We pay for them to protect them militarily and they play us in trade. So it is not a good combination,” he stressed in words collected by The Country. The problem for Europe is that the trade deficit of the United States with Europe in the purchase and sale of cars was and continues to be very high. And the North American Government is not willing to accept that Europe compensates part of these losses (and other products sold to the United States) with services. Despite everything, the balance remains positive for Europe, as seen in this graph of elDiario.es. According to ACEA15% of the vehicles exported by Europe are destined for the United States. However, the value is high because 22% of the money made from exports to the entire world comes from the United States. Those 38.5 billion euros contrast with the 7.7 billion euros that we import from the country. By units, Europe had shipped 749,170 light cars to the United States the previous year, while we had purchased 164,857 vehicles. On average, a car sold to the United States costs about 51,400 euros. Back, each car sold by the United States to Europe costs about 46,800 euros. This explains to us that if the United States only wants a balanced trade balance between entry and exit of vehicles, it is almost impossible to achieve. But there are many reasons why Europe cannot match the sales that the United States makes of our cars. Firstly, due to a purely cultural problem, the United States does not manufacture cars that fit the European philosophy. In general, they manufacture extremely large cars for European cities, with larger and more fuel-efficient engines than European ones. And not only that, the United States has encountered the problem that a large part of the automobile manufacturing industry has left the country to locate in Mexico and Canada. Trade agreements with these countries allow them to sell cars “American style” by producing them cheaper than within their borders. Europe has been finding a productive market for each car. Those with a higher cost (but a higher profit margin) are manufactured, above all, in Germany and France where costs are higher. The smallest ones are produced in Spain or in countries with lax trade agreements such as Morocco or Türkiye. Only within its borders (Germany and Poland) do distortions occur, such as that between the United States and Mexico and Canada. The problem for the United States is that the Europeans do manufacture cars that are of interest there, sending them from Europe or from Mexico and Canada, but they also already manufacture the cars that the Europeans themselves are interested in. The United States manufactures a type of vehicle that is little in demand in Europe and, in fact, brands like Ford have been manufacturing the vehicles that interest us … Read more

paying 920 million a month to SpaceX

Elon Musk created SpaceX for space exploration, reducing costs related to transportation and ultimately colonizing Mars, but what he has found is a vein on Earth: Google and SpaceX They just signed a lucrative agreement of infrastructure that puts Elon Musk’s space company at the center of the enterprise AI ecosystem. Among other things, because it is not the first agreement it has signed of this type: in May it already made same with Anthropic. Bottom line: Google is going to pay SpaceX almost a billion dollars a month to lend it computers. It may be a simplification, but it is not an exaggeration: SpaceX has tens of thousands of the most powerful graphics cards in the world in its data centers and Google urgently needs them so that its artificial intelligence continues to stand up in the AI ​​battle. 920 million dollars a month. That is the agreed price for the rental of part of its processing capacity, specifically 110,000 Nvidia GPUs, CPUs, memory and related components, from October 2026 to June 2029. That is, approximately $30 billion over the life of the contract. The rollout will be progressive, so until its entry into force in October, Google will pay a lower rate. To put the movement in perspective, Jensen Huang, revealed As of October 2025, the company had shipped a cumulative total of 4 million Hopper GPUs (H100 and H200) and 3 million Blackwell GPUs since its launch. The 110,000 GPUs in the Google and SpaceX contract are equivalent to what Nvidia ships globally in about a week at the current production rate. Why is it important. Because it is a reflection of the current state of the race for AI: Google is a company with plenty of financial and technological muscle. Without going any further, Google together with Amazon and Microsoft control more than 60% of the global cloud infrastructure market, according to data from Synergy Research (yes, with a 14% share in cloud infrastructure (IaaS/PaaS), it is the third in contention). And still it is not enough: TechCrunch collects the statements from a Google representative explaining that demand for Gemini Enterprise has even exceeded their expectations. For SpaceX, the impact is tremendous: the space launch company has managed to partially and on the fly convert itself into a cloud infrastructure provider. The agreement also comes at the perfect time: one week before its shares begin trading on the Nasdaq. Documentation provided to the Securities and Exchange Commission reveals that Musk’s company intends to raise $75 billion at a valuation of approximately $1.75 trillion, the largest IPO in history. Context. As we mentioned in the intro, the agreement reached between SpaceX and Google is similar to the one reached with Anthropic at the end of May and by which the company led by Dario Amodei agreed to pay $1.25 billion per month until 2029 to rent all the available capacity of the Colossus 1 data center in Memphis, Tennessee. As a curiosity, this center was initially built by xAI, now integrated into SpaceX. Alphabet, Google’s parent company, is investing ruthlessly. Already is committed more than 180 billion dollars to spend on technological infrastructure in 2026 alone and has announced an expansion of 80 billion more. The agreement with SpaceX is the bridge while it materializes. In detail. As with the agreement with SpaceX, there is a cancellation clause: if it fails to provide access to the number of GPUs committed by September 30, 2026 (just one day before the full deployment takes effect), Google can either accept the number provided with a reduction in that quota or cancel everything. Likewise, both SpaceX and Google can terminate the agreement simply with 90 days’ notice after December 31, 2026. Important: Google retains all intellectual property of its AI models, content and data even if they run on SpaceX servers. SpaceX puts in the machinery, but doesn’t have access to what’s inside. Yes, but. The cancellation clause puts a possibility on the table: that SpaceX cannot provide those 110,000 operational GPUs before September 30, 2026, something essential to close this lucrative agreement under the terms described. This agreement with Google and the previous one with Anthropic put an obvious conflict of interest on the table: SpaceX is an infrastructure provider for two of the big rivals of xAI and its Grok models, so Elon Musk finds himself in a curious situation: he is the one who decides which infrastructure he gives up and which one stays. We do not know which SpaceX data center will be for Google and Musk has already indicated, according to TechCrunchthat Colossus 2 is reserved for xAI.

Spain is 2º C warmer than in the 80s

When a new summer season arrives, almost all of us have a conversation that includes one sentence: “Every year it gets hotter; the summers before were not like that.” And although for some it may seem like a true exaggeration based on nostalgia, the reality is that the data confirms that we really do have much hotter summers. Certificate. Multiple independent studies, supported by official organizations such as the State Meteorological Agency or the Ministry for the Ecological Transition, have reached a devastating conclusion: the average summer temperature in Spain has increased around 2 °C in the last three decades. Although this is not the worst, because even the nights are no longer a refuge from the heat that occurs during the day. The data. If we look at the thermometers with the perspective that time gives, the trend is an ascending line without brakes. According to the Sustainability Observatory, if we compare the decade of 1969-1978 with that of 2009-2018, the average summer temperature has gone from 21.4 °C to 23.8 °C, so there is talk of an increase of 2.4 °C. But it is not necessary to go that far to notice the acceleration of the phenomenon, since the weather reports most recent from MITECO and AEMET point out that the summer of 2025 broke all records since 1961, reaching an average peninsular temperature of 24.2 °C, which represents an anomaly of 2.1 °C above the average we had as a reference, surpassing the previous record held in 2022 of 24.1 °C. Endless summers. The heat is not only more intense, but it lasts much longer. According to AEMET Open Data, the climatological summer current lasts five weeks longer than in the 80s, gaining ground on spring and autumn at a rate of 9 days per decade. And since 1975, the summer heat period has been officially lengthened by 20 days. The impact is even greater in urban environments, where asphalt and concrete act as heat accumulators, as stated in a study by the Polytechnic University of Catalonia that analyzed the period 1971-2022 in peninsular cities and shows chilling figures: an increase of 3.54°C. Tropical nights. During the summer, many of us wait for nightfall to get the temperatures to drop so we can go outside or sleep more comfortably. However, the nights when the thermometer does not drop below 20 ºC They are the order of the day. And to give us an idea, there are 32 million Spaniards regularly affected by these suffocating nights. In Spain as a whole, they have increased an average of 6 days in the last 50 years. If we focus on specific areas, Andalusia, Murcia and the Valencian Community, citizens today suffer 12 more tropical nights a year than a few decades ago. And the reality is that to sleep this becomes very complicated, forcing the use of the beloved air conditioning or fan.

They have asked a Galician judge if Raynair and Vueling can charge for hand luggage. The answer could not be more Galician

Two years later, it will be Europe that contributes its point of view. The answer will be key to deciding whether Ryanair, Vueling or Volotea can charge for hand luggage. The decision falls on a court in A Coruña, after the Public Prosecutor’s Office sued these three companies. Those involved will have to wait to know what the High Court of Justice of the European Union says. The demand. Ryanair, Vueling and Volotea are three companies that have been operating at A Coruña Airport. All of them are low cost and are known for applying very strict measures when it comes to hand luggage. So strict that passengers have been allowed for years only with a small backpack if they do not want to face an extra cost on their flight. The Public Prosecutor’s Office, however, considers these practices to be abusive. It is the same line that the Government has followed, which even sanctioned the three for this luggage policy. In that fineRyanair with more than 100 million euros in punishment was the one that had the worst stoppageBut the legality of that fine is in doubt. And what has happened? That the A Coruña court handling the matter has referred the matter to the Superior Court of Justice of the European Union (CJEU), as explained in The Mediterranean Newspaper. Now, the CJEU must give a reasoned response to the matter and with this response the magistrate will decide. For now, the procedure is suspended. This occurs because the magistrate handling the matter requires the involvement of Brussels in two questions. The first is whether the European Union’s freedom of pricing regulations go against Spanish regulations that require airlines to allow free travel with hand luggage. And, second, if this extra price on the ticket is an abuse of consumers. There is nothing clear. It is not the first time that a Spanish magistrate asks the CJEU for help. The question raised refers to a similar decision taken in 2014 in favor of Vueling, but according to the judge, that victory for the airline is not enough to now settle this new confrontation. And justice itself in Spain has taken decisions that may seem contradictory. In fact, there are two very clear examples: The airline wins: last year, in SevilleRyanair won a trial in which it was accused of a position of power by charging for hand luggage. The passenger wins: also last year, in SalamancaRyanair lost a trial in which 147 euros were claimed for charging a passenger for a carry-on suitcase on different routes between 2019 and 2024. Why does it happen? The problem is that the rules that regulate air traffic do not clearly specify what is or is not carry-on luggage. And they do not specify minimum measurements either. This has caused tension in Spain that is repeated. For the Government, the measures used by low-cost companies They are clearly insufficient to carry the essential luggage. On the contrary, these companies defend that they do allow a backpack to pass under the terms offered and that the law protects them when they decide to price larger packages. Furthermore, they point out that on their planes there are no spaces for all travelers to carry their luggage in a suitcase, but the Government defends that if the luggage fits under the seat, this cannot be an excuse. And Europe has already positioned itself. The problem is that Europe has already taken a position repeatedly on this issue. First, we know that the European Union has worked on a new regulation in which it will specify what minimum measures are required… and the problem for Spain is that These measures coincide with those requested by Ryanair on its trips. Furthermore, the Transport Commissioner of the European Commission seems to have positioned itself clearly in favor of companies. In fact, a file has already been opened against Spain for the fine imposed on Ryanair and the rest of the low-cost companies in relation to the charge for hand luggage. With everything and until there is a clear ruleit seems that the conflict can be repeated over time.

It refreshes us but gives us torticollis

When summer arrives, it is easy to see how thermometers reach 40 ºC, or even before, how we are suffering right now. Here the air conditioning in the office, at home or even in the car becomes our best ally, since at first glance it is seen as an indispensable lifesaver. However, scientific literature tells us that it also has quite negative effects that go beyond the classic cold due to the extreme temperature changes that we face. The most general effects. Centralized air conditioning systems are a problem, as has been documented by science itself, since it has been seen that they are direct sources of health problems if the indoor air quality is not optimal. And the consequences are quite clear: dry eyes, headache, fatigue and difficulty concentrating. With concrete data. A study published in 2023 with 400 adults in India compared people who were exposed to air conditioning versus those who used natural ventilation in their daily lives. What was seen is that users who were regularly air conditioned suffered many more cases of dry eyes, pharyngitis and nasal congestion than those who were in more natural conditions. But in addition, medical tests showed that lung function was significantly lower in people under constant air conditioning. Specifically, 35% of them developed rhinitis, compared to only 9% in natural ventilation environments. The consequences. This impact on health translates into lost days, since people who work with air conditioning missed an average of 22 days a year, compared to just 13-15 days for those in offices without artificial air conditioning. Muscle pain. Something that I have personally heard a lot, especially from older people, is that air conditioning makes them have severe ‘bone pain’, especially if it hits them directly. And the reality is that direct cold triggers a defense mechanism in the body to increase the temperature and stay at 36-37 ºC. through muscle contraction. So, if the exposure of the muscle to the cold of the air conditioning produces a muscle contraction, it means that those people who set the air conditioning to 18 °C see their maximum grip strength decrease by 20% and the speed of development of that force plummets by 50%. In the cervical This is where it has been clearly seen that superficial cooling increases the tension of the sternocleidomastoid muscle, which explains the classic torticollis. But they even explain the facial paralysis that occurs due to exposure to these jets of frozen air and that we colloquially call ‘it has given him a wind’. Pollution. If the air conditioner cools, but its filters are not maintained, the device becomes a diffuser of pathogens. This is especially important in hospital centers where the prevalence of diseases can increase. nosocomial. But in Spain the most serious danger has a name and surname: Legionella pneumophila. This is a bacteria that finds its perfect ecosystem in cooling towers and air conditioning generators, causing legionellosis, which is a very important atypical pneumonia condition. The protective character. If the air conditioning has high-efficiency filters, the picture changes radically by eliminating these pathogens. But the most interesting point is in a 2017 study involving 200 participants in Taipei that showed that air filtration improves cardiovascular health by reducing fine particles and volatile organic compounds from the outside. The ideal temperature. Knowing all this, what is the balance point? The consensus of experts and clinical studies indicates that the thermostat should be between 24 °C and 25 °C. Medical evidence indicates that going below 20°C guarantees the appearance of significant musculoskeletal problems and would also irritate the bronchial mucosa, which would be a major problem for patients who have lung disease. And if you want to have a refrigerator at home below 17ºC, the clinical literature points to significant exposure to respiratory and also joint problems.

the story of how Ridley Scott blew our minds in the most terrifying scene in cinema

One of the most disturbing inspirations of Alien He was not born in a Hollywood studio, but in a doctor’s office. For years, screenwriter Dan O’Bannon suffered from Crohn’s disease and he described some episodes as the sensation of having something alive trying to break through from inside him. That experience would end up becoming in the seed of one of the most disturbing images in the history of cinema. The scene that changed terror. In 1979, Ridley Scott took a unusual decision even by horror film standards: hiding from their own actors a good part of what was going to happen during one of the key sequences from Alien. The director was convinced that performed fear could never equal real fear. The script barely indicated that “something emerges”but the exact appearance of the creature, the amount of blood, the violence of the scene and the way everything was going to unfold remained deliberately hidden for most of the cast. That commitment to surprise would end up giving rise to one of the most shocking, imitated and studied scenes in the entire history of cinema. The origin of the nightmare. The famous chestburster sequence It was not born solely from the imagination of its creators. Dan O’Bannonscreenwriter of Alien, wore years fascinated by parasites and by some of the most brutal reproductive mechanisms in the insect world. Wasps that lay eggs inside other animals, larvae that grow by feeding on a living host, and organisms capable of controlling the behavior of their victims served as inspiration for the creature. To this added an experience much more personal: the severe intestinal pain derived from Crohn’s disease that O’Bannon himself suffered from. The feeling of having something growing and fighting By coming out of his interior he ended up becoming the central idea of ​​the monster that would end up terrifying the public. The battle for the perfect alien. Once the idea was conceived, O’Bannon knew exactly who should give it visual form. During his experience in the failed project of Dune by Alejandro Jodorowsky had discovered the work of the Swiss artist HR Gigerwhose biomechanical illustrations mixed sexuality, death, bones and machinery in a way never seen before. The problem was that the producers and the studio considered those images too disturbing and they resisted hiring him for months. Everything changed when Ridley Scott joined the project, saw Giger’s designs and was completely fascinated. Their support was decisive in incorporating the artist, a decision that would end up defining the visual identity of Alien and much of subsequent science fiction. A monster inspired by nature. The creature was also not conceived as a simple aggressive alien. O’Bannon wanted his life cycle to be as disturbing as it was plausible. The facehuggerin charge of implanting the embryo in the victim’s body, was born from the combination between the screenwriter’s ideas, Giger’s designs and the work of various artists and technicians. The goal was to create an organism that would use humans as involuntary guestsreproducing in a horror key some behaviors observed in real insects. The true horror of Alien came not only from the physical violence, but from the loss of control over one’s body and the feeling of becoming a vessel for something unknown. Preparing for the big shock. Ridley Scott was aware that the alien birth sequence would decide the success or failure of the film. If the public took it as a joke, the whole threat would disappear. That’s why he spent weeks perfecting the creature’s design and carefully planning the shoot. HE built an artificial torso for John Hurt, the actor who played Kane, and a complex hydraulic system was installed under the table. The fake breast was stuffed with real organs obtained in butcher shops and slaughterhouses, in addition to seafood and organ meats that provided a texture that was impossible to reproduce with the effects of the time. To give us an idea, the smell was so intense that the cast themselves I would remember decades later the mixture of formaldehyde, blood and decaying flesh that permeated the set. Giger airbrushing an alien hieroglyph showing the violent and parasitic life cycle of the Alien The best kept secret. The actors knew that something was going to come out from Kane’s chest, but they were practically unaware everything else. While technicians worked for hours preparing the special effect, the cast remained away from the set. When they were finally called to film, they found a stage covered with plasticscameras protected by transparent tarps, buckets scattered everywhere and team members wearing raincoats. Nobody explained to them the reason. That strange atmosphere generated a growing tension that Scott deliberately sought. I wanted the cameras to capture real uncertainty, not just interpretations. Giger’s first failed attempt to create a chest-busting alien, inspired by Francis Bacon Reality surpassed acting. The filming was not as simple as it is usually remembered. The first attempts failed because the creature could not properly pass through Kane’s shirt and some blood systems were blocked. However, these errors had an unexpected effect: They further increased the anxiety of the actors, who saw how something seemed to try to make its way from inside their partner’s body without understanding exactly what was happening. When the tiny bug finally managed to emerge and jets of blood began to shoot in all directions, the reactions were authentic. Veronica Cartwright received a direct hit in the face that she did not expect and ended up emotionally overwhelmed. Sigourney Weaver confessed that at that moment she was not even thinking about the film, but about John Hurt. Yaphet Kotto was so affected that, according to several testimoniesisolated himself for hours after filming. The scene that no one forgot. There is no doubt, Scott got exactly what he was looking for. The expressions of astonishment, horror and revulsion that appear on the screen belong largely to people that they were living something unexpected before your eyes. The director summarized years later … Read more

Some astronomers made a paella at 2,000 meters above sea level in Almería. And they discovered the best cooking point for rice

If you like cook a paellait is best that you do it on the coast. And not only because of how pleasant the impression of having a rice at the beach bar looking at the sea is. Also because, basically, it will cook better. Astronomers know this well. Calar Alto Observatoryin Almería, who have a curious anecdote with this story. It wasn’t the chef’s fault.. Years ago, the astronomers at the Calar Alto Observatory enjoyed the dishes prepared by a magnificent chef, from a small town in the province of Almería, during their work days. In his municipality he was known precisely for the quality of his rice. However, I had a thorn in my side with the paellas I was trying to prepare at the observatory. Rice never suited him. At least, not as tasty as normally. In Xataka We have spoken about it with Ana Guijarro, one of the astronomers at this observatory. One day she explained to him that he should not martyr himself. The fault was not his, but rather the fact that the facilities They are 2,168 meters above sea level. The physics behind. As we rise meters above sea level, the atmospheric pressure is lower. To understand it, we can visualize it: there is less column of air above our heads, therefore there is also less pressure acting on them. The boiling point of liquids depends on the pressure. If we heat waterthe molecules that make it up will move faster and faster, colliding with each other. When they reach the surface, they may attempt to “escape,” turning into vapor. However, atmospheric pressure pushes them down and prevents this from happening. If the atmospheric pressure decreases, so does the boiling point. That is, the temperature at which the liquid can begin to turn into vapor. At sea level, the boiling temperature of water is 100ºC. However, at 2,168 meters, water boils at approximately 92.6ºC. A cooking class. For rice to cook properly, it is necessary for the starch in its grains to hydrate and gelatinize correctly, and for that to happen, sufficient heat is needed. The problem is that, when a liquid boils, all its energy is invested precisely in that change of state instead of continuing to raise the temperature. The 100ºC at sea level, or 92ºC at higher altitudes, remain stable so that the liquid turns into a gas. Therefore, there is not enough temperature to process the rice grains in the best possible way. And what about Andean rice? In the Andean countries there are many rice-based dishes that are very tasty. The height is even higher than that of the Calar Alto Observatory, but in these places, where they have no choice but to cook at high altitudes, They have a very precious trick: the pressure cooker. Precisely the objective of this utensil is to artificially increase the pressure, so that the boiling point rises and the food can be cooked for longer. It is valid for rice and all types of stews. Even at sea level it is very precious for cooking certain dishes, such as stews. Sometimes physics makes it difficult for us, but there are tricks to deal with it. It’s not just a matter of rice. Ana Guijarro tells us that this does not only happen with rice. “For example, tea or any infusion They don’t taste the same in the mountains, because the water boils at a lower temperature and that affects the extraction of the flavor that these things have.” It is something that can frustrate a chef a lot, but with which people who, like astronomers, usually work many meters above sea level, are more than familiar. Better paella on the beach. In short, the next time you have a paella on the beach, remember that it is the best place you can have it. And everything is much more enjoyable when you know the science behind it. Images | MagnificentJorgechp In Xataka | The paella Taliban have been growing strong for years. More and more evidence points to the contrary.
