Antimatter has a property that has taken physicists decades to measure. CERN just did it a hundred times better than anyone else

by

Antimatter is fascinating not only because of its essence; It is also due to the still enigmatic role he played in the origin of the universe. Scientists still do not have the necessary tools to understand with any precision the role of this form of matter in the formation of the cosmos and the mechanisms that govern the tenuous line that delimits the imbalance between matter and antimatter. Fortunately, what they do know are its constituent elements and some of its properties. Understand what is antimatter It’s not difficult. And we can observe it as an exotic type of matter that is made up of antiparticles, which are particles with the same mass and spin as the particles we are familiar with, but with the opposite electrical charge. In this way the antiparticle of the electron is the positron or antielectron. And the antiparticle of the proton is the antiproton. Antimatter has a surprising property: when it comes into direct contact with matter, both annihilate, releasing a large amount of energy in the form of high-energy photons, as well as other possible particle-antiparticle pairs. It is currently being studied in many of the most important research centers specialized in particle physics in the world with the hope that knowing it better will help us understand some of the mysteries of the cosmos that remain out of our reach. The hyperfine cleavage of antihydrogen has been revealed CERN’s antimatter factory produces this form of matter by firing high-energy protons from an adjacent synchrotron at a metal block. This process generates a cascade of secondary particles, and among them antiprotons arise. These latter particles can then be cooled to be used in the facility’s experiments. ALPHA (Antihydrogen Laser Physics Apparatus or antihydrogen laser physics apparatus), which is one of them, is specialized in producing antihydrogen by fusing antiprotons with positrons. Researchers then use magnetic fields to trap the antihydrogen for further study. An antihydrogen atom is composed of an antiproton in its nucleus and a positron orbiting around it, in the same way that a hydrogen atom contains a proton around which an electron orbits. Deuterium and tritium, the two isotopes of hydrogen, also have one or two neutrons in the nucleus respectively. The researchers of the ALPHA experiment have achieved something amazing: have measured hyperfine division of the ground state of the antihydrogen atom with a precision of 4 parts per million, improving the previous result by two orders of magnitude. This milestone is very important because it allows very rigorous tests to be carried out in the field of quantum electrodynamics. Hyperfine splitting of the ground state of the antihydrogen atom is the small splitting of the lowest energy state of the atom due to the magnetic interaction between the antiproton and the positron. According to the fundamental symmetries of nature, this measurement should be identical to the equivalent effect observed in hydrogen. Be that as it may, this milestone is very important because it allows very rigorous tests to be carried out in the field of quantum electrodynamics, which is the most precise theory that explains the interactions that occur between charged particles and light. Jeffrey Hangst, the spokesperson for the ALPHA experiment, explains that “the hyperfine splitting of the ground state of hydrogen is the origin of the so-called 21 centimeter lineso prized by radio astronomers and researchers searching for extraterrestrial intelligence (…) When the antimatter factory was conceived in the 1990s, the hyperfine splitting of antihydrogen was one of the key measurement objectives justifying the construction of the facility.” “The current measurement represents the culmination of many years of effort,” Hangst pointed out. “We have pursued the precise determination of the hyperfine splitting of antihydrogen since we demonstrated how to trap antimatter atoms in 2010. And now another group in the antimatter factory, the ASACUSA collaboration, is also trying to study this very important transition. Their technique, if demonstrated, has the potential to achieve even greater precision.” Thanks to ALPHA’s high level of precision, the measurement of hyperfine cleavage is sensitive to the effects of the internal structure of the antiproton at the center of the antihydrogen atom. In any case, this result is a very important step in the effort to further explore the nature of antimatter.

China is taking away all its scrap paying up to five times more

by

The scene seems like something out of an industrial espionage thriller, but it takes place in broad daylight. As anticipated Financial TimesChinese buyers are making appointments in the parking lots of stores like Home Depot in the United States to discreetly purchase lots of scrap metal valued at more than $20,000. This is the front line of a silent war for global resources. According to this same media, Asian intermediaries are sweeping up American scrapyards and paying up to five times the usual price, snatching the material from local recyclers. The director of a recycling company in Texas sums it up bluntly: “it’s a secret war that no one talks about.” Why so much interest in residual remains? The answer lies in the metal that makes them up. As explained The Conversation, Tungsten – whose name means “heavy stone” in Swedish – has the highest melting point of all known metals, reaching 3,422 °C. Furthermore, its extreme hardness and resistance to thermal shocks make it an absolutely irreplaceable material for manufacturing everything from aerospace technology to armor-piercing military ammunition. Market strangulation. China currently controls almost 79% of global tungsten production. As detailed in an analysis by expert John Connortension erupted in February 2025, when Beijing tightened its export controls in retaliation for US tariffs, cutting its shipments to the West by a drastic 40%. The economic impact of this decision was devastating. The restriction caused a strangulation of the market and a brutal increase in prices, which shot up 557% to reach $2,250 per metric ton. The great paradox is that, while the global shortage of virgin tungsten is caused by Beijing’s quotas, it is China itself that hoards recycled American scrap—such as worn-out industrial drill bits—to take it back to Asia through third countries such as Canada or Dubai. Industry analysts warn of imminent danger: If China officially reopens its doors to direct imports of scrap metal, the result will be a disaster for supply in the rest of the world. The global board. Today, almost absolute control of these supply chains gives China immense commercial and geopolitical power. This dominant position allows Beijing to use critical technologies and materials—so-called “bottlenecks”—as a lever of international influence that it can pull at will. Faced with this drain on resources, the debate has reached the highest levels. The report of Financial Times collect voices within the recycling industry and the US Congress demanding an immediate ban on the export of tungsten scrap to China to protect national security. However, the United States faces a temporary impasse: the country currently lacks the processing capacity necessary to convert all that exported scrap into useful finished products for its industry. In search of extraction. As Connor explainsthe solution inevitably involves diplomacy and investment abroad. The expert points out that Kazakhstan, which has the largest reserves of tungsten outside China (estimated at about two million tons), has become the center of the US strategy, attracting government-backed investments to develop local mines. But the race is head to head and Beijing has not sat idly by. In fact, China has already moved ahead in the Central Asia region, having started commercial production at the gigantic Boguty mine in Kazakh territory. At the same time, new Western actors are trying to close the gap. The financial portal Trading View informs that companies such as the Canadian mining company Allied Critical Metals are committed to revitalizing historic European projects, such as Borralha in northern Portugal. The company has a clear objective: to start the production of tungsten concentrate before the end of 2026 to meet the urgent demand in the West. Industrial ingenuity versus dumping. The middle The Conversation provides a historical parallel extremely interesting: during World War II, faced with the critical shortage of molybdenum caused by attacks by German submarines on maritime convoys, engineers from the British company Vickers managed to innovate by recycling the metal directly from mining drill bits. Today, that same logic applies to tungsten, which has a very high recycling rate of 42% globally. In Western markets this figure shoots up to an impressive 70%, driven precisely by the need to compensate for Chinese dominance over the primary mineral. In addition to technical innovation, state protection strategies gain prominence. In March South Korean Sangdong mine opened; Once at full capacity, this facility could produce more than 80% of the world’s non-Chinese tungsten. The most notable thing about this project is that the Seoul government has established a guaranteed minimum price for the mineral, thus protecting the operation from possible practices of dumping. Flooding the market to artificially depress prices is a tactic China has used successfully in the past to bankrupt Western investors in the critical minerals sector. An imminent warning for the West. The clock is ticking and the consequences of inaction could be fatal. An imminent and dangerous reality stalks the West: the Third Gulf War has consumed munitions at a staggering rate and depleted US stockpiles of tungsten-dependent missiles such as the Patriot and THAAD systems. taking them to historic lows. Without a stable and massive supply to quickly replenish these arsenals, the US military risks a true military disaster should a larger conflict break out, such as a direct confrontation over Taiwan. As a final reflection, andThese restrictive tactics from Beijing should be read as a stern warning. The current tungsten crisis should force Western governments to wake up once and for all and “de-risk” (de-risk) urgently their supply chains. Only by building an independent industrial network can the Western world avoid making its security and economy dependent on the monopoly of a single country.

everything we think we know so far about the next version of Apple’s mobile operating system

by

Let’s tell you everything we think we know about iOS 27based on all the leaks and rumors around the next version of Apple’s mobile operating system. Like every year, the months leading up to the imminent presentation of the new version of the system have left us with a whole collection of rumors and leaks that we are preparing to review. Here, what you should know is that everything we are going to tell you is based on the rumors and leaks that have been released about iOS 27. When it is officially presented we will update the content so that you can know with certainty all the official changes. When do we expect iOS 27 to be released The new iOS 27 will be presented on June 8 this 2026, during the long-awaited WWDC 2026. This is the annual event organized by Apple to announce its upcoming software news, where the new versions of the rest of its operating systems will also be presented. That same day the first beta is expected to be releasedalthough for now it will be for developers. This is at least what Apple usually does, although we will have to wait for official confirmation to be clear. After several developer betas, it is expected that Starting in July, public betas begin to arrive that any user can download by simply registering in the beta program. Normally the final version of iOS 27 will arrive in September along with the presentation of the new iPhone 18. But here the leaks outline some possible changes. Specifically, it is possible that only the iPhone 18 Pro and a new folding iPhone will be presented in September, while the “normal” iPhone 18 may not arrive. until spring 2027. However, there are no confirmations on this either, only rumors. What news do we expect from iOS 27 Let’s tell you what they are the rumored news of iOS 27. According to rumors and leaks, everything seems to indicate that after having finished with the aesthetic innovations of iOS in recent years, now it will be the turn of stability and performance. This is what we know to date. More performance and more stability As they point out in Applesferaleaks from the renowned Mark Gurman aim to eliminate the “technical debt” that has been accumulating after years of adding layers of software. Now it’s the turn to polish the system inside to optimize it as much as possible. This means that a restructuring of the internal code is expected so that iOS 27 is much faster and smootherthat bugs that consume battery are eliminated, and that it flies regardless of the age of the iPhone. There will be no new icons, there will be no flashy redesigns, but there will be noticeable differences in fluidity. An even smarter Siri We’ve been talking for several versions of iOS about Siri being smarter and using AI, but so far everything has been delayed. However, we hope that the new Siri finally arrives with iOS 27and that this Siri will also have an artificial intelligence model based on Gemini. The agreement between Apple and Google gives those from Cupertino full access to Gemini. With this, it is suggested that Apple could try to distill Gemini and create smaller adapted versions that can work locally on your mobile. With this, in addition to offering greater privacy, they will also have more efficient and faster operating models. Come on, Apple privacy and Google intelligence. The leaked renders This new Siri will show dark background and will be integrated within the dynamic island. When you launch Siri, it will tell you that you can search or ask whatever you want. The interface will be different from the old Siri so that they are unmistakable. Siri will also have a live conversational mode like Gemini, to be able to chat by voice, as well as multitasking that allows you to do several things at the same time. You will also have full control over iPhone apps and settings, and possibly a new way in the camera carousel to use visual intelligence and analyze what you point at. The new smart Siri will also have advanced writing tools such as Grammarly-style grammar check, AI wallpaper generator within Image Playground, or camera options with which to change the perspective of an already taken photo or expand photos. They will also include shortcuts with natural language which will mean that you no longer have to configure several steps, a smart wallet to create digital passes by scanning the physical object, smart tab management in Safari, and additional functions for the Health app. Additionally, there are leaks indicating that Siri in iOS 27 could also let you choose what a task is solved by Claude, Gemini or ChatGPT in case it is necessary. Thus, Apple’s new AI will not seek to be the best, but rather to solve your problems and serve as a gateway for other models on the iPhone if necessary. Lastly, if you don’t like any of this it is also expected that there will be a switch in settings to be able to deactivate the new Siri with AI. This, by the way, arrived in Beta status. Other news And now we leave you the list with the rest of the news that has been leaked to date. In addition to the novelty, we will also include a small description so you know what it is about. Perfecting Liquid Glass: There have been internal changes at Apple with the departure of the head of design and the rise of a veteran to top manager, so it is uncertain how much Apple’s Liquid Glass will be improved. At the moment we are talking about Liquid Slider, a slider that allows you to choose the intensity of the transparency. Undo and redo when rearranging widgets or apps: The arrival of a system that allows you to reverse accidental changes when organizing desktop apps and widgets has been leaked. … Read more

“The need to actively capture CO₂ is increasingly evident”

by

Nations’ current climate commitments are not enough to meet the trajectories needed to maintain global warming below the limit of 1.5 ºC that we have marked. The solution to the climate crisis It is no longer just about stopping broadcasting greenhouse gasesbut requires direct action to literally collect them from the atmosphere and store them in some way. A warning. As he warns the third edition of the report State of Carbon Dioxide Removalhumanity would need to expand technology to eliminate CO₂ at a rate comparable to, or even greater than, the expansion of solar energy and electric vehicles. The biggest audit. This report is truly important as it is the first global, independent and accessible scientific assessment of how carbon dioxide is being removed. This edition has been prepared by an interdisciplinary team composed by more than 50 scientists from highly prestigious institutions, including the University of Oxford and the University of Wisconsin-Madison. To ensure transparency, this assessment includes an open data portal detailing performance indicators. CDR and allows you to monitor where, how and how much CO₂ is actually being eliminated around the world. Where are we? Although we are already working to eliminate carbon dioxide from our atmosphere, the figures indicate that we are very far from the goal that would allow us to breathe a little easier. To be clear about the numbers, global CO₂ removal levels are around 2.2 gigatonnes per year. And although it seems like a gigantic figure, the reality is that 99.9% of this elimination is carried out through conventional methods. This fits with the histories compiled in the 2024 edition led by the University of Oxfordwhich already indicated that the world removed about 2,000 million tons per year, depending almost exclusively on reforestation and land management. The objective. In order to meet the 1.5 °C objective that we have set for ourselves as a society, it is essential to multiply our capacity, since it points to the need to eliminate 5 gigatonnes of CO₂ by the year 2050. And for this, the strategies that different governments are following are not designed to even come close to this figure. Technology. Achieving this massive expansion will require a true technological revolution. Methods evaluated for their potential and costs include bioenergy with carbon capture and storage, direct air capture, and advanced afforestation techniques. In addition to large-scale implementation, science continues to look for cutting-edge solutions and, in Spain, for example, CSIC research centers They study novel methods such as the photoactivation of CO₂ using titanium dioxide and copper clusters. The experts. Here Science Media Center has collected the impression of different critical voices, such as that of Raffaele Bernadello, researcher in the Climate Change group of the Barcelona Supercomputing Center, who points out that “the need to actively capture CO₂ is becoming increasingly evident as a complementary measure to the rapid and marked reduction in emissions” On the other hand, Ana Hernández, biodiversity and natural resources planner at the Climate Research Foundation, also points out that “temporarily exceeding the 1.5 °C threshold is practically inevitable, given that the remaining carbon budget will be exhausted around 2030.” Images | Chris LeBoutillier In Xataka | The easiest way to understand global warming, in this climate map with data from 1940

China has launched an underwater creature into the sea that defies naval engineering

by

Year 1953, the US Navy launches USS Albacorean experimental submarine whose “water drop” shape seemed so strange that it broke with decades of naval design. Many officers doubted the concept, but it ended up being just as effective underwater. that ended up influencing in practically all modern submarines built since. More than seventy years later, another image of a submarine with an unconventional silhouette once again raises the question of whether we are seeing the beginning of a new revolution. The creature that breaks the rules. The satellite images captured in a Shanghai shipyard have revealed something extraordinary: a large Chinese submarine that looks like dispense with the sail or tower command, the structure that for more than a century has been considered an almost mandatory piece in underwater engineering. The appearance of this design has attracted attention because it challenges one of the most established conventions of modern naval warfare. It is not a small experimental prototype, but rather a platform for about 120 meters in lengthlonger than many nuclear attack submarines currently in service, suggesting that China is exploring concepts much more ambitious than a simple technology demonstration. Designed to perform underwater. The main advantage of removing the candle is purely hydrodynamic. When that large structure that protrudes from the hull disappears, the submarine reduces resistance As it advances, it improves its fluidity in the water and can optimize speed, maneuverability and acoustic discretion. The less noise a vessel generates, the more difficult it is to detect it using sonar, a fundamental aspect of modern underwater warfare. Added to this is the possible incorporation of an X-shaped tailassociated with greater navigation agility and safety, as well as the probable use of an encapsulated propeller pumpjet typea technology intended for reduce further the noise during submerged operations. Images of the new submarine at the JN Shipyard in Shanghai on June 1, 2026. The importance of what is missing. Precisely because the sail has been a universal feature on modern submarines, its absence raises numerous questions. Traditionally this structure houses periscopes, sensors, antennas communications, electronic masts and ventilation systems. It also provides an elevated position for surface navigation, improves the crew’s situational awareness and can even be used in certain logistics missions or operations under the polar ice. Giving it up means accept limitations important operational functions, so Chinese engineers must consider that the benefits obtained compensate for these sacrifices or that there are technological solutions capable of replacing part of their functions. Images of the new submarine at the JN Shipyard in Shanghai on June 1, 2026. Eight years of silent experimentation. Because as they remembered TWZ analysts, The appearance of this submarine has not arisen from nowhere. The same shipyard already built in 2018 a much smaller vessel that also lacked a sail and likely served as a test bed to validate design concepts. That prototype practically disappeared from the public spotlight for years, but it now seems clear that it was part of a broader research program. The progression from a model measuring just 45 meters to a platform that rivals nuclear submarines in size shows that China has spent years perfecting this idea before taking the next step. Images of the new submarine at the JN Shipyard in Shanghai on June 1, 2026. The link with the submarines of the future. The initiative also fits with other signals recently observed in the Chinese shipbuilding industry. In 2024, the CSSC state corporation presented a concept of a large unmanned underwater vehicle whose silhouette was remarkably reminiscent of these low-profile designs. That project contemplated missions as diverse as attacks against ships, laying mines, supporting special forces or even acting as a mother ship for other underwater drones. Although the new submarine detected seems too large to be completely autonomous, the similarity between both concepts suggests that China could be developing a family of platforms based on the same design philosophy. An army in full transformation. We have been counting it. The appearance of this submarine coincides with a profound modernization of the Chinese submarine force. Beijing is incorporating increasingly advanced models, developing new submarines nuclear weapons and even experimenting with hybrid designs capable of combine different shapes of propulsion. US officials have recognized on several occasions that the quality of Chinese submarines is progressively approaching that of the most modern Western models. In parallel, the People’s Liberation Army Navy continues to expand to a higher pace that of any other navy in the world, driven by the need to project power in the Pacific, the South China Sea and other strategic regions. More questions than answers. Of course, the official name of the submarine, its internal systems or the exact mission for which it was conceived are still unknown. However, satellite images have left an impression hard to ignoreA: China appears to be testing an idea that for decades was relegated to theoretical studies, experimental prototypes and laboratory concepts. If he project prosperscould mark the beginning of a new generation of submarines where the traditional command tower ceases to be an unquestionable necessity and becomes another option within the evolution of underwater warfare.

“A structured resistance routine with appropriate series and weights is sufficient”

by

When you enter the world gym it is quite likely that two great mantras: “You have to change exercises constantly so that the muscle does not get used to it” and “The more sets and weight we load, the more the muscle will grow.” However, the latest scientific evidence is dismantling these popular beliefs piece by piece to make way for much more efficient training. A new study published in April in the journal Research Quarterly for Exercise and Sport forces us to rethink how we create our routines, especially if we are looking to have a much larger arm. To do this, the researchers set out to resolve a fundamental question: is it really necessary to increase the number of sets or vary the exercises constantly to continue gaining muscle? To figure it out, they recruited 32 young adults with no prior strength training experience and subjected them to a 14 week protocol. The first six weeks were standard conditioning, where all participants gained a remarkable 4.0% of lean mass in their upper limbs, measured with extremely high precision using scanners. DEXA. The real test came over the next eight weeks, where they divided the subjects into four groups. Here one group kept the same basic routine, while the second group increased the number of sets they did of an exercise and the third also changed the type of exercise. And to bring it all together, the fourth group of young people increased both the number of series and the type of exercise. The result. There was no statistically significant difference between these four groups, since the group that limited itself to doing the basic routine with sufficient effort gained 3.1% of lean mass, even surpassing the group that had much more weight in its exercises and technically tying with those who varied exercises. The conclusion that can be drawn here is good news for beginners, since overcomplication offers no magical advantages over a solid and consistent routine. A bad idea. The conception we have that the muscle gets used to exercise and needs a “surprise” for it to start growing as we want, the truth is that it is a myth, as we are seeing. And in case there was any doubt, another article published in 2022 analyzed more than 240 participants to see if varying exercises had any type of advantage. Here it was seen that varying systematically can help regional hypertrophy, but changing too quickly or without any strategy behind it can compromise muscle gains. And if you change your routine every week, the nervous system spends time learning the coordination of the new movement, instead of effectively recruiting muscle fibers to make them grow. How much do you have to train? If constantly changing isn’t the key, is living in the gym? Here a large review crossed data from 4,784 people to determine what is recommended It is a minimum of 10 weekly series per muscle group to optimize hypertrophy. When it comes to frequency, the reality is that training a muscle once a week or three times gives very similar results as long as the total weekly weight is the same. This means that, if you do 12 sets of biceps a week, it doesn’t matter if you do 12 on Monday, or 6 on Monday and 6 on Thursday. Don’t change for the sake of changing. Instead of randomly varying exercises, science suggests choosing the most biomechanically effective movements and progressing through them. Here, a study done in 2023 compared triceps training with the arms above the head versus neutral positions and the result was clear: the overhead position generated 28.5% hypertrophy in the long head of the triceps, compared to 19.6% in the neutral position. They did not grow more because they were “confusing the muscle,” but because the elongated position generated greater mechanical tension. With all this, we must keep in mind that the change of exercises must be done according to biomechanics and with a sense behind it.

with 20,000 Pa, self-emptying base and simultaneous scrubbing

by

The robot vacuum cleaner sector continues to take steps towards that ideal goal of completely forgetting about the broom. iRobot has just made a move in Spain with the arrival of its new model: Roomba Combo Plus 415 Plusa proposal that seems to want to simplify daily maintenance just when the heat and movement of summer dirty the house the most. Its launch price is 499 euros. This is not just another vacuum cleaner, but an attempt by the brand to integrate the scrubbing and suction in a more compact body It moves easily between the legs of chairs and under furniture. iRobot Roomba® Plus 415 Combo The price could vary. We earn commission from these links Powerful suction and scrubbing that knows where to stop If we take a look at what it offers under the hood this robot vacuum cleaner Roomba, we can say that it can boast of a suction power of 20,000 Paa figure that on paper should be more than enough to deal with the finest dust and the heaviest debris. The curious thing is that they have managed to put all that force into a slightly smaller chassis than its predecessors, making it easier for the robot to reach those corners where it simply couldn’t fit before. For those who have carpets at home, the detection system seems to be well resolved, since it is capable of raising the mopping mop by about 10 millimeters to avoid accidental moisture on the fabrics. As for mopping, the device is not limited to moistening the floor. It uses a system that exerts a little more pressure in complicated areas, trying to imitate the manual gesture to remove stains. All of this is supported by a navigation based on LiDAR sensorswhich basically serve so that the robot knows where it is at all times and does not waste time repeating areas or crashing into the obstacles that we leave in the way on a daily basis. For those looking for comfort, probably the biggest attraction of this new iRobot Roomba is its new maintenance station. We are no longer just talking about the robot emptying its tank automatically so that we don’t have to do it every two days, but the base now also takes care of the hygiene of the mop. At the end of its route, the system can wash the cloth and, perhaps most useful to avoid those annoying musty odors, apply a jet of hot air to dry it completely. All this technology is managed from an app that has been polished over the years to be more intuitive. From your mobile you can organize the rooms, put up virtual barriers or simply let them the robot learns from our habits to suggest when it is due for a thorough cleaning. ⚡ IN SUMMARY: iRobot Roomba® Plus 415 Combo robot vacuum cleaner ✅ THE BEST Hot air drying: The fact that the base dries the mop at 45º is a great plus point, since it solves the typical problem of bad odors due to humidity that other hybrid models suffer from. Actual mop lift: The fact that the mopping cloth rises 10 mm when detecting a carpet gives great peace of mind, because it prevents the textiles from ending up wet or with dirty water stains. ❌ THE WORST Wash with cold water… Although the base dries the mop with heat, pre-washing is done with room temperature water, which may fall short of completely disinfecting if there are stubborn grease stains on the floor. Consumables dependence… Both the dust base bags and the specific mopping liquid or the mops themselves represent an extra maintenance cost that must be assumed over time. 💡 BUY IT IF… You want to ignore floor cleaning almost completely for weeks, delegating both vacuuming and maintenance of the mopping cloth itself. ⛔ DON’T BUY IT IF… You expect the robot to remove dried stains from days ago or to completely replace the traditional mop in deep cleanings, it is possible that the system falls a little short.

Argentina wants to get rid of parents who do not pay their children’s pensions. So he kicked them out of the football stadiums

by

To enjoy a soccer match in an Argentine stadium it will no longer be enough to have a ticket. From now on, fans must comply another extra requirementequally or even more important: being up to date with your children’s pensions. In an attempt to hit where it hurts most, the football heart of the nation that gave birth to Maradona, Messi or Di Estéfano, the authorities have activated a system that prohibits access to the fields to parents who ignore the costs of feeding their children. The Government has 13,000 people in its sights, defaulters whom it just got complicated for them also the USA World Cup. “They don’t enter the fields anymore”. The phrase is from Alejandra Monteoliva, Minister of National Security, who recently announced, via Xthe decision to close the stadium doors to those who are not up to date with their pensions. “Delinquent food debtors no longer enter the fields. Starting today, together with the Government of the City of Buenos Aires, we incorporate debtors into the Safe Tribune program. And they will no longer be able to go in to watch a soccer game,” explains Monteoliva before underlining the basic idea: “He who does not comply with his children, off the courts.” Is it something new? Yes. And no. ‘Safe Tribunes’ It is not a new program. Carry years applying in Argentina and its objective is to reinforce access control to sports events, although until now the focus has been focused mainly on violent fans, accused, convicted or with arrest warrants. It is basically dedicated to checking the documentation of those who go to the camps to check their history or even if they are carrying drugs or knives. For a while now some jurisdictions of the country, as Buenos Airesalso decided to veto sporting events for those who do not comply with the alimony of their minor children. As a reference, the Buenos Aires authorities they assure that since March 2025, 173 controls have been carried out that have made it possible to identify 150 “delinquent food debtors”, fans who were prevented from accessing stadiums or concerts. “So far in 2026 alone, 84 have already been carried out with 75 offenders.” What’s new then? That Argentina has decided to go one step further, combining and reinforcing both initiatives: ‘Safe Grandstands’ and restrictions on access to stadiums for parents with debts. For this, the Ministry of National Security and the Government of the Autonomous City of Buenos Años have signed an agreement that “marks a qualitative leap” in field controls throughout the country. The key is in the exchange of information, which will allow thousands of new names to be included in the ‘Safe Tribune’ red list. To be more exact, we talk about 13,000 people, “delinquent obligors” registered in Buenos Aires and 13 other provinces spread across the country, such as Chaco, Entre Ríos, Formosa, Tierra de Fuego, Santa Cruz or Tucumán. From now on all of them will have a difficult time when they want to watch games in the stadiums, at least as long as they do not catch up with the food pensions they owe. Click on the image to go to the tweet. “Consequences”. Alejandra Monteoliva has not been the only one to insist on the advantages of the system. Something similar has been done, too. via Xthe head of Government of the Autonomous City of Buenos Aires, Jorge Macri: “In the city a year ago we prohibited the entry of food debtors to stadiums and mass shows. Now, in joint work with the Government, we added our database to the Safe Tribune program to reinforce these controls throughout the country. Anyone who does not comply with an obligation as basic as feeding their children must have consequences.” Where it hurts the most. In his message, dated May 26, Macri left bouncing another fundamental idea: access controls with the debtor registry in hand will not only be done in the country’s stadiums; The idea is that they will also be applied during the World Cup. Milei’s team has sent a list to the US with more than 30,000 Argentine fans who have restricted access to the World Cup stadiums, which will start in a week in Mexico. And these include, confirms Monteolivathe 13,000 delinquent parents. It is not just another announcement or a declaration of intent. The new restrictions in Argentine stadiums have become official already in the Official Gazette and the Executive has also published a resolution (444/2026) announcing the sending to the US Embassy of information on people with restrictions to access sporting events. The measure is adopted based on the cooperation agreements signed between both Governments and its list would include the “alimony debtors”. Some sources they assure that the veto will extend to Canada and Mexico, the other hosts of the FIFA Cup. Is the problem so serious? In case the 13,000 registered in the system do not give a clue, in 2024 Unicef ​​provided another even more emphatic one: that year it published a report in which it warned that 56% of mothers living in Argentina do not receive child support when the father does not reside in the home, a percentage that rises to 68% if we include mothers who do not receive it regularly. Field access restrictions will only apply when there is a judicial or administrative resolution that demonstrates non-payment and the affected person appears in the official registry of defaulters.

He showered them with 500 million dollars

Larry Ellison He is known for being a co-founder of Oracle, a close consultant on AI in the Council of Advisors on Science and Technology of Donald Trump’s second term and the second largest fortune in the world, according to the list of millionaires of Forbes. The millionaire invested hundreds of millions of dollars in a technological agriculture project on Lanai, his private island in Hawaii, as published The Wall Street Journal. His idea was to revolutionize the way they produce food through an innovative and sustainable approach, combining advanced technology with methods of modern hydroponic farming. To carry out the project, Ellison created the company Sensei Ag, which promised to develop an innovative vegetable growing model that would multiply the food production in the future. However, this ambitious plan has not developed as Ellison expected and has become another example of the technological challenges that agriculture faces. Lanai, Ellison’s Paradise In 2012, Larry Ellison bought 98% of the island of Lanai, in Hawaii, for just under 300 million dollars. Their intention, in addition to turning it into their vacation retreat, was to transform it into a sustainability laboratory. One of its key projects was the development of vertical farming by Sensei Ag, which aimed to produce fresh and healthy food using less land area and natural resources. According to WSJEllison allocated an initial investment of 500 million dollars with the objective of building six greenhouses equipped with high technology and design a smart irrigation system that optimize water use. “Greenhouse structures were optimized for tulips in Holland in the 17th century and have not undergone major improvements since then,” said David Agus, a friend of Ellison and one of the founders of Sensei Ag. Sensei Ag built greenhouses and equipped them with advanced sensors, artificial intelligence and climate control systems. These greenhouses had to ensure the conditions conducive to producing fruits, vegetables and other high-quality foods, reducing the environmental impact. Furthermore, the Oracle founder planned to use renewable energy to power these facilities to create a complete sustainable model, so that it could be deployed in other parts of the world. The island did not make it easy for them. If something can fail, it will fail In the 1920s, Lanai became a huge estate dedicated to pineapple cultivationto the point of producing 75% of the world’s supply of this fruit. This intensive cultivation and chemical agents used To accelerate ripening, they wreaked havoc on the fields, which reduced the productivity of the island’s soil. The island’s climate also posed problems as the Israeli engineers who built the greenhouses did not take into account either the island’s humidity or its gusts of wind. Therefore, the coverage of 12 million dollars from the greenhouses flew through the airshooting up the repair cost to $50 million. Elon Musk, a personal friend of Larry Ellison, was in charge of provide solar panels that would feed greenhouse technology. However, again the strong winds They constantly dirty the panels that were left unusable. As pointed out in the article The Wall Street Journalon many occasions they had to obtain electricity by connecting diesel generators. In addition to failing roofs, solar, and land, Sensei Ag employees had to deal with an unexpected problem: Wifi coverage failures. It may seem like a lesser evil, but in a high-tech greenhouse where there are hundreds of sensors that regulate light, temperature, humidity or ventilation, having Wi-Fi makes the difference between a successful harvest or a failure. 500 million dollars worth of cherry tomatoes Although the Sensei Ag plans were very ambitious, the project faced the same profitability dilemmas that farmers suffer in any corner of the planet. “The vision was very big, but then it slowly became diluted as we faced the realities of implementation on Lanai,” said En Young, former general manager of the Lanai facility. The operating costs of advanced facilities and the maintenance of the greenhouses were too high compared to the income generated from the sale of food. And Sensei became the largest producer of different types of lettuce and cherry tomato from Hawaii. Its founding goal of “feeding the world” has been an absolute failure. Now, the project will focus on the development of agricultural management software, using its greenhouses as a testing laboratory, with the aim of selling the necessary software and hardware in the form of a package that other farms can franchise. In addition, it has begun operations in southern California to implement robotic cultivation systems to automate the care of the plantations, and acquired 11 hectares south of Austin (Texas) and the former headquarters of the robotic farming company Iron Ox. The investment amounts to 40 million dollars with which it intends to expand its market beyond Hawaii. For Lanai, the partial closure of the Sensei Ag project raised questions about Ellison’s long-term plans for the island. Some residents criticized that their agricultural resources were used for technological experiments rather than to help the island’s supply of provisions, which must import between 80% and 90% of the products it consumes.

It is charged by the sun and costs less than 100,000 pesos

Mexico has just joined in this affordable electric mobility. And the company TT Automotive presented the TT01 a few days agoalso named “Totally Tlaxcalteca”, a small electric and solar vehicle manufactured almost entirely in the state of Tlaxcala. The meeting was at Hacienda Soltepec, in the municipality of Huamantla, where businessmen, state and federal authorities, and representatives of the automobile sector attended. It is the pride of the region, since the project boasts that around 80% of its components are of national origin. We tell you everything in detail. Why is it important. The TT01 is proposed as one of the cheapest electric cars that can be found today in Mexico. According to the brand, its price part of the 99,000 pesos (about 5,000 euros to change) and goes up to 160,000 pesos in its most equipped versions. That entry figure places it even below Oliniathe electric car project promoted by the federal government of Claudia Sheinbaum, which has not yet reached the market. So basically the company has preempted the state initiative. Simple and without airbags. The TT01 stands out from the rest of the urban electric cars in that it uses a charging system using solar panels integrated into the roof. According to their creator, Edgar Guzmán Carreto, founder of TT Automotive, these panels generate up to 50 kilometers of autonomy after eight hours of exposure to the sun. The car can also be plugged into any conventional household outlet. The company talks about a total autonomy of up to 250 kilometers per charge, a maximum speed of 50 km/h (little, but designed especially for the city and short trips), capacity for five passengers and a body with a high-strength steel structure. The Herald of Mexico itself says that this first model incorporates very very basic security measures. And because it doesn’t have, it doesn’t even have airbags. Between the lines. In the presentation, Guzmán Carreto counted that TT Automotive was born “not only as a company, but as a declaration of principles”, with the idea of ​​putting technology at the service of people. The approach is to have a cheap car ready, manufactured locally and aimed at families, delivery people and neighborhood transportation. The assembly is carried out in the Xiloxoxtla Industrial Park, which, according to those responsible, should generate employment and strengthen the supplier chain in the area. Pay attention to the nuances. The TT01 that was shown in Huamantla is still a prototype, and there are details that deserve our attention. On the one hand, the vehicle can also be recharged with gasoline in the event of possible unforeseen events. On the other hand, the company itself recognizes that it is still looking for investors to be able to manufacture on a large scale. Guzmán Carreto estimates that in about six months they would be able to produce in series, with an initial goal of 20 units per week and first sales through its website. It is worth remembering the history of delays of the project, since it was first announced in September 2025 with the promise of going on sale in December of the same year, and in the end it was postponed until it was officially presented a few days ago. And now what. The company also works in other variants with greater speed and pricewith versions for personal, family and distribution use, according to pv magazine. Now we need to know if TT Automotive meets the deadlines, since if so it would be ahead of Olinia’s proposal. It remains to be seen whether this type of vehicle, so special and with very basic security systems, will arouse interest in the region.
