In Mexico, Generation Z has taken to the streets to demand changes. And he did it with ‘One Piece’

by

Mexico has joined the wave of protests youth events that over the last few months have shaken Nepal, Sri Lanka, Bangladesh, Peru, Morocco either Philippinesto cite a handful of examples. Marches that share two great hallmarks. The first, who promotes them: young people from Generation Z (born between the late 90s and the first decade of the 2000s) raised in the heat of the networks and now crying out for change. The second, its symbol. It does not matter whether the protests are organized in Lima, Kathmandu or Mexico City. Beyond using networks as catalysts, the mobilizations of Generation Z usually resort to the same emblem: the pirate flag from ‘One Piece’, the manga of Eiichiro Oda that the protesters have turned into their most identifiable banner. And not just because of the flag. In the marches it is also common to see other clear nods to the comic, such as the use of straw hats. How did you get to Mexico? After weeks of brewing online, the most visible mobilization in Mexico took place this weekend, when thousands of people gathered in the capital to make clear their “political fatigue”. The authorities speak of around 17,000 attendeesa human tide that left the monument The Angel of Independence and concluded in the Zócalo. The call was for the most part peaceful and passed without major incidents, beyond the insults to the president (Claudia Sheinbaum); but it was marred by the final altercations, which left more than a hundred of injured (mostly police officers) and several dozen arrested. In fact, the Ministry of the Interior assures that during the “violent acts” homemade explosive devices were used and objects were thrown at the agents. Who took to the streets? Some media they assure that among the protesters there were mainly young people, others qualify that during most of the Mexico City march, Generation Z was a minority and the most common thing was to meet people who were over 30 years old. Sheinbaum herself influenced that message later, commenting on what happened on Saturday in Mexico City: “They say that young people marched, but in reality there were very few, and they violently removed fences and broke windows. No to violence.” The truth is that, beyond Mexico City, there were mobilizations in other points of the country, such as Yucatán, Puebla, Monterrey or Guanajuato, and among the protesters they waved the banners of ‘One Piece’. Also posters demanding improvements in the country and Mexican flags with the face of Carlos Manzothe local leader of Uruapan shot to death just a few weeks ago. His death (a new example of the violence in the country) was in fact one of the levers of the protests. Click on the image to go to the tweet. And why did they go out into the streets? The other key. The TendenciaMax account (656,600 followers) echoed a few weeks ago a manifesto headed by “Generation Z Mexico” and the ‘One Piece’ flag (modified to add a mustache and Mexican hat), on which keys to the call were slipped. To begin with, it was insisted that the movement does not endorse any ideology or party and lacks “disguised agendas.” “We are young people who love our country and we are tired of the same history, the same abuse and corruption.” During the march people could be heard expressing their exhaustion with the violence, insecurity, Sheinbaum’s management or even denouncing that Manzo “the State killed him”. The word “narco-state” was also drawn on the wall built by the authorities to protect the Presidential Palace from protests. Excelsior slips that another point that has caused tension to grow is the decision to apply a 8% tax to video games with violent content. In the opinion of the Executive, the protest is orchestrated actually by the opposition and reply to an “articulated digital strategy” in networks by dint of bots. Why ‘One Piece’? If spontaneous mobilizations have something, it is that it is not easy to define them. Gen Z marches are no exception. Although in recent months they seem to have gained strengthspreading through Asia, Africa and Latin America, the truth is that they can go back even further in time, to student uprising of Bangladesh that led the prime minister to flee to India, or the 2022 revolt in Sri Lanka that forced the president to resign. What they have in common is the mobilization of Generation Z and the fortune that ‘One Piece’ seems to have made in their imagination, something that it doesn’t seem casual. The comic began to be published in the late 90s and continues to be updated, so its popularity has coincided with the Gen Z boom, and much of its plot fits in with the demands of the protests. After all, its main character, the young and charismatic pirate Monkey D. Luffyis presented as a figure of liberation.

The enormous Mayrit tunnel boring machine on Metro L11 is already in Madrid. Now comes the real challenge: putting it together piece by piece

by

In Madrid there are already the pieces of one of the largest machines that will work in the city’s underground in the coming years. It is about Mayritthe EPB tunnel boring machine 98 meters long and 1,500 tons in weight whose transport started in Germany, continued along the Rhine to Rotterdam and continued by boat to the port of Santander. After that journey, a special convoy has completed more than 450 kilometers by road to take its modules to the future Comillas station, where it will prepare to excavate the new section of Line 11 between Plaza Elíptica and Conde de Casal. The work on which Mayrit will work is part of a broader intervention that the Community of Madrid describes in 2025 as the largest expansion of the Metro network in the last decade. Official data published in November put progress at 34% and maintain a budget of 518 million euros to complete the new section and the planned stations. The regional government maintains the year 2027 as a reference to close this phase of the project. Mayrit is already in Madrid: one hour left to convert its parts into a single operational machine When dealing with a machine of this size and complexity, each phase of the process requires precision that goes far beyond conventional engineering. Mayrit’s journey towards Spain began long before it appeared on the road: it started in Schwanau, the German town where Herrenknecht completed its manufacturing after about 20 months of work. There, more than a thousand kilometers from Madrid, the tunnel boring machine It was assembled for the first time in June 2025 to carry out initial verifications. This assembly showed the magnitude of the next step: converting the machine into a set of parts capable of traveling around Europe without risks. Disassembling it was not a quick procedure. For the next two months, Herrenknecht teams dedicated themselves to separating each module following a sequence calculated to the millimeter. The result was a set of sections ready to begin an international tour. The disembarkation in the port of Santander marked the beginning of the last stage of Mayrit’s journey, a phase that requires coordination very different from that of river and maritime transport. The pieces arrived distributed in separate shipments and were transferred to prepared platforms, a process that is carried out with specialized equipment to avoid any unexpected displacement. The organization of the road transfer incorporated common protocols in special transport, with large-tonnage vehicles escorted by technical teams in charge of checking clearances, turning radii and urban accesses. The authorities confirmed that the advance was carried out mainly at night to reduce interruptions and facilitate maneuvers in the most delicate sections of the route. The arrival in the Comillas area required a final deployment of personnel and machinery to accommodate each piece in the work area, where the assembly phase that will transform this set of modules into a single operational tunnel boring machine is already awaiting. The arrival of the pieces also marks the beginning of a phase that, according to forecasts distributed between June and November 2025, can extend until March 2026. Assembling a TBM requires joining modules in a strict order, connecting hydraulic and electrical systems, and performing tests that are concentrated between late January and February. It is a sequential process that is not resolved in a few days and that determines the date on which the machine will be able to start digging at the beginning of March. The official documentation describes Mayrit as an EPB machine adapted to the geotechnical characteristics of the layout. Its operation is based on maintaining a balance of pressures that prevents unwanted movements on the surface, especially relevant in urban environments. To sustain this process, shifts of specialists are involved who manage the control and evacuation systems of the excavated material. The expected performanceclose to 15 meters per day, will be decisive in setting the pace of mechanized advance. Comillas will be the point from which Mayrit will begin the mechanized sectionaccording to the forecasts that the Community of Madrid has been detailing since June 2025. From there it will advance to Conde de Casalwhile in parallel the manual excavation of about 700 meters towards Plaza Elíptica progresses, started in September with a performance of close to 50 meters per month. The beginning of the excavation will mark the jump between the preparatory work and the actual progress of the tunnel that will transform this section of Line 11. With each meter excavated, the planned layout will get closer to its final shape and will allow the progress of the project to be measured more clearly. It is a significant element within regional planning to reinforce mobility in one of the areas with the most demand on the network.

Researchers find a piece of ice from six million years ago. What is really valuable is the air trapped inside

by

A team of scientists has achieved something extraordinary in the frozen Allan Hills, east of Antarctica: extracting 6-million-year-old ice samples, the oldest ever directly dated. Trapped inside are air bubbles that date back to Earth’s Miocene atmosphere, when our planet was much warmer and sea level considerably higher than today. A time capsule in the form of ice. The discovery, published in the journal PNAS on October 28 and led by Sarah Shackleton of the Woods Hole Oceanographic Institute and John Higgins of Princeton University, more than doubles the age of the oldest known ice so far, which dated to about 2.7 million years ago. “Ice cores are like time machines that allow scientists to take a look at what our planet was like in the past,” explains Shackleton. “The Allan Hills cores help us travel much further back than we thought possible.” How they found it. Between 2019 and 2023, the Center for the Exploration of Older Ice (COLDEX) team drilled between 100 and 200 meters deep into the ice sheet in the Allan Hills region, located about 2,000 meters above sea level. Just like they count From the Middle Space, this area is especially valuable because the topography of the terrain and ice flow patterns allow extremely old ice to be preserved closer to the surface, unlike the Antarctic interior where it would be necessary to drill more than 2,000 meters to reach similar ages. Dating. The researchers They determined the age of the ice measuring the radioactive decay of argon isotopes present in trapped air bubbles. This method allows ice to be dated directly, without the need to examine the rocks or soil around it. The result: 6 million years, a time when the Earth was home to now extinct creatures such as saber-toothed tigers, arctic rhinos and the first mammoths. Cooling. Analysis of oxygen isotopes in the cores revealed that the Allan Hills region has cooled approximately 12 ºC during the last 6 million years. It is the first direct evidence that quantifies how much the Antarctic climate has cooled since that ancient warm period. Ed Brook, director of COLDEX and paleoclimatologist at Oregon State University, stands out that “the team has built a library of what we call ‘climate snapshots’ about six times older than any previously reported ice core data.” Why does it matter? While Antarctica and the Earth as a whole have progressively cooled for millennia, humans are now rapidly increasing global temperatures by release large amounts of greenhouse gases to the atmosphere. Studying these bubbles of ancient air will allow scientists to reconstruct past greenhouse gas concentrations and ocean heat levels, which could give us clues to what natural factors have contributed to the climate. climate change throughout the entire history of our planet. Surviving extreme conditions. “We are still discovering the exact conditions that allow such ancient ice to survive so close to the surface,” points out Shackleton. “Along with the topography, it’s likely a mix of strong winds and intense cold. The wind blows fresh snow and the cold slows the ice almost to a stop. That makes Allan Hills one of the best places in the world to find shallow old ice, and one of the toughest to spend a season in the field,” he continued. Next steps. The COLDEX team plans to return to Allan Hills in the coming months to carry out more drilling. They hope to recover even older samples and produce a more detailed record of Earth’s ancient atmosphere. “Given the spectacularly old ice we have discovered in Allan Hills, we have also designed a new comprehensive long-term study of this region to try to extend the records even further in time, which we hope to carry out between 2026 and 2031,” concludes Brook.

The United States is offering millions of dollars to quantum companies. In exchange, he wants to keep a piece of each

by

The United States has opened a new stage in its industrial policy. This time it is not about aid without return or simple soft loans: Washington is offering millions of dollars to quantum companies in exchange for a share in its capital. The information comes from the Wall Street Journalwhich points out that the agreements seek more than just supporting promising companies. The message is clear: the Government wants to ensure a seat at the table for a technology that can reconfigure the economy and global power for decades to come. The initiative fits into a chain of recent decisions in which Washington has been deepening its presence in sectors considered strategic. The Government transformed almost 9,000 million dollars in previous aid to Intel in a participation close to 9.9% and obtained special rights in US Steel to oversee sensitive corporate decisions. He also supported MP Materials in the critical mineral chain. The signal is clear: when the sector is considered vital, Donald Trump’s White House seeks to stay on board. When public money also buys influence Conversations affect some of the most visible names of the American quantum ecosystem. According to the newspaper, companies such as IonQ, Rigetti Computing and D-Wave Quantum They are negotiating with the Department of Commerce the entry of the State into their capital. Other firms, including Quantum Computing Inc. and Atom Computing, are studying similar deals. Operations would start from a minimum of 10 million dollars per company in this initial phase, with the possibility of more applicants joining as the program progresses. The conditions are not limited to a mere public investment. The Commerce Department is studying formulas ranging from equity stakes to intellectual property licenses, royalties or revenue sharing schemes. The conversations are led by Paul Dabbarformer executive of the quantum sector and current number two in the department, according to published information. At this stage there are no closed agreements, but the approach indicates that the State seeks a tangible return and supervision tools. Washington’s interest is not explained only by financial reasons. Quantum computing is emerging as one of the technologies with the greatest capacity for industrial transformation. These machines promise to solve calculations that would take eons to current systemswith potential applications in fields such as drug design, advanced materials or highly complex chemistry. Adding to this momentum is international competition, with companies like IBM, Microsoft and Google involved and China advancing its own quantum race. The security dimension adds another layer of urgency. Quantum algorithms are projected to They may violate traditional encryption systemsincluding RSA and ECC, exposing both sensitive communications and critical infrastructure. The risk is not limited to the future: the strategy known as harvest now, decrypt later suggests that malicious actors are already collecting encrypted data for decryption when this capability becomes available. Given this scenario, Fortinet highlights the need to move towards post-quantum cryptography and strengthen networks and systems. The practical potential of this technology is well illustrated by the pharmaceutical sector. McKinsey highlights that quantum can transform drug development by enabling precise molecular simulations, something that classical calculus and pure AI fail to always capture. Large companies are already testing these systems to study proteins, evaluate chemical reactions or reduce experimental steps. This ability to model complex structures from scratch promises to accelerate research, improve the success rate in trials and shorten times to market for new therapies. The implementation of this approach is not limited to companies. According to the Wall Street Journal, the Commerce Department reorganized the office responsible for the scientific side of the CHIPS program and recovered several billion dollars that had been allocated to previous technology initiatives. The political message is transparent: the Executive wants public investments to be measurable and for the State to have mechanisms to benefit when the funded projects mature, especially in sectors with high strategic involvement. The shift raises dilemmas typical of a more interventionist model. Public participation can facilitate stability in strategic sectors, but it also opens the door to conflicts between technological, industrial or political priorities. The central doubt is to what extent the presence of the State will affect the pace of decision and the flexibility that the most competitive sectors demand. There are still relevant unknowns. The final percentages that the State could reach or the exact conditions that would accompany the participations are not known. According to the information available, the agreements are still in the negotiation phase and could be modified before being closed. It also remains to be seen what commitments will be required of companies and whether there will be associated performance or governance criteria. At this point, the process is moving forward, but a definitive schedule for awards or formalization of agreements has not yet been announced.

Every minute that passes is a piece of Napoleonic jewel that will never be recovered

by

From the moment it was known theft of the Napoleonic jewels Inside the Louvre in Paris, France began two parallel races where they sought to try to recover part of the loot. The first one didn’t last long. The next day he found out that he was not going to receive a single euro. by insurance because French law prevented it. The second, and more complicated, is a race against time, because every second that passes is a piece that may not be able to be recovered. A global black market. I counted this week The Wall Street Journal that the assault on the Louvre has immediately activated the semi-clandestine ecosystem through which stolen art and, in particular, historical jewels circulate: an international circuit that moves billions and that connects diamond cutting workshops in Dubai or Delhi with discreet jewelers in New York, Antwerp or Tel Aviv. The priority now is not only to recover the pieces, or those that can, but to do so before they come in on that circuit and suffer the most feared fate: being dismantled, separated from their mount and converted into anonymous gems and molten gold without a past. Jewelry is not paintings. Unlike a Picasso or a serial watch, a stolen jewel can disassemble in minutes: the gold melts, the diamond is cut, the emeralds are rearranged and historical traceability disappears. Although they lose their premium for Napoleonic symbolic value, they retain their value as raw material. The situation reinforces the incentive: the ounce of gold exceeds $4,000 after go up 60% in one year, detonating a wave of metal thefts throughout Europe. And unlike pictorial art, ancient gems lack microengravings or universal databases that allow them to be blocked from being released to the market: once split and relocated, they disappear. The method. The media counted this week that the coup combined speed and daring, but left a trail unbecoming of a professional command: the assailants used a moving elevator to access through an upper window, burst display cases with radials and fled on scooters… leaving abandoned the elevator itselfthe tools, part of the costume (work vests) and even an imperial crown from the 19th century with 1,400 diamonds and 56 emeralds. For former specialized agents, this distances the Pink Panthers profile (disciplined groups that leave no trace) and suggests a bold but technically weak team, capable of entering, but not maximizing value or minimizing exposure. What will the thieves do now? For the Journalif the museum does not pay a reward or admit negotiation, the only viable commercial path is cutting and atomization: re-cut large diamonds into smaller sizes to erase the mark, separate secondary stones easily absorbed by the gray trade and melt the gold to sell it as metal. The experts remember that a receiving network remains up to 90% of value: the thief usually receives only 10% of the legal market (the “price of silence” that is distributed among those who participate in the risk, the conversion and the shielding of concealment), but even so the black reward can be higher than that of a stolen painting, the trace of which jumps to public bases. The crux. The incentive persists because the penalties are low compared to profit and because the stolen jewel, once decomposed, leaves few traces to incriminate. Experts they propose to reclassify the looting of heritage as cultural terrorism (harnessing penalties and sending a regulatory signal). Plus: it forces museums to raise standards physical and procedural, from the control of systems such as cranes or external platforms to, as a deterrent idea, verifying the identity of visitors elevated to sensitive parts, although this clashes with the tourist experience and the flow of masses. The Louvre remained closed after the robbery, remembering that beyond the property loss there is an immediate reputational and operational cost. It only works in the shade. Everything in the jewel crime revolves around at speed: the faster they pass into the hands of cutters and smelters, the more irreversible the evidentiary damage is and the more liquid the exit to the black market. Delay, on the other hand, increases the logistical risk, multiplies leaks within the criminal chain, opens cracks for denunciations and devalues ​​the loot before it produces income. That is why the decisive race is not so much between thieves and insurers, but between stopwatches: the clock that marks how long it takes the receivers to volatilize the identity of the pieces compared to the one that measures how long it takes the State to close the perimeter and cut escape routes. The only window. If you want, the Louvre robbery embodies the Achilles heel of historical jewels: they allow a high-profile crime with a low profile outlet because their cultural identity is destructible at the will of the gangsters and its material value remains. The paradox is that an imperial loot can end up becoming in minor gems sewn into the lining of a jacket heading to an unknown jeweler before the police complete the first sweep. Thus, the only real window to rescue the assets is not in the trial, but in the very brief interval between the blow and the cuttingand once that threshold is crossed, what is stolen ceases to exist as part of history to survive only as matter.

The border between Morocco and Algeria was closed in 1994. 30 years later, the fight threatens to claim its most unexpected piece: the date

by

A strong, dry, accurate blow is enough. Only one, in the center of the chest. When this happens, the diaphragm contracts violently and the body exhales all the air it has inside: the person is temporarily unable to inhale. That is exactly what happened to the international date market on October 10, 2025: it was left breathless. And the reason was a misunderstanding. That and a very long diplomatic conflict that always ends up affecting Spain. What has happened? October 10. The advice of GIDattes (the Tunisian interprofessional date group) published a statement in which the start of exports was announced of dates. Business as usual, really. But they added a clarification that set off all the alarms: “to all markets except the Moroccan one.” In a matter of hours, everyone interpreted that Tunisia was vetoing the export of these fruits to the west. October 13 and 14. Given the widespread noise and uncertainty in the sector, the GIDattes He clarified that there was no type of exclusion. Simply put, as it is the main export market, These required a special calendar that would be approved on October 20. October 19, 20 and 21. But it was too late, the Moroccan employers’ associations and producer groups had smelled blood. For the first time in years, there was a 20% chance (19.7% in 2024) of the dates consumed by the country would disappear from the equation: the profits for local producers would be enormous. October 21. After the meeting on the 20th, the Tunisian press reported that there would indeed be exports to Morocco at the end of October: “like every year“. What does Algeria have to do with all this? Moroccan farmers have gone directly to where it hurts most: they have accused Tunisian dates of be Algerian. It is, moreover, a classic accusation of the Moroccan countryside. Something that no one can completely rule out (due to the traditional traceability deficits of the Maghreb), but that no one really takes seriously. Although it is not going through its best moment, Tunisia is a giant in the world of dates. He doesn’t need Algeria at all. But Algeria is a sensitive issue in the western end of North Africa. A little context. The historical enmity between Morocco and Algeria can be traced back to the very independence of these territories: border disputes ended up leading to the War of the Sands of 1963 and, above all, in the Algerian support for the Polisario Front in Western Sahara. In 94, an attack in Marrakech (in which two Spaniards died) caused a diplomatic conflict that closed the enormous land border between both countries. They have not been reopened and, in fact, in 2021, diplomatic and commercial relations they are broken. Suffice it to say that, if the accusations of the Moroccan producers are confirmed, the Tunisian date would disappear from the markets of the Alawite state. Why is all this so important? This has had an impact on the international date market because, although Tunisia is in the doldrums (and Saudi Arabia has overtaken it in recent years) it is still the second country in date exports. A decision such as that of vetoing the largest importer of dates in the world, Morocco, would have caused a violent restructuring of commercial networks around the globe. To all this we must add a key fact: the third country in date exports, Israel. Today (with or without a peace agreement) no one knows exactly what will happen to the tens of thousands of tons that the Hebrew country puts on the market each year. And that, logically, generates even more uncertainty. The important thing is in the details. In dates, for example. In recent days Steve Witkof and Jared Kushner (Trump’s special envoys) revealed that they were working to reach an agreement between Morocco and Algeria that would solve the Sahara issue. It is quite possible: the US president’s obsession with ‘ending all the world’s wars’ may have put a conflict like this in the spotlight. One, furthermore, that involves a traditional ally of Washington. However, dates show us that everything is more complicated than it seems. Is the delicate balance of the Mediterranean about to be blown up? We will see it in the coming months.

McDonald’s has a problem in Japan with the dolls of ‘One Piece’ and ‘Pokémon’ of the Happy Meal: they sell too much

by

McDonald’s is running in Japan with a reception of such caliber for his Happy Meals that he is being forced to cancel promotions early. First with letters from ‘Pokémon‘And then with dolls from ‘One Piece’the traditional gifts of their children’s menus are being grass of collectors that are generating A crisis not only foodbut also of image. What happened. This last August McDonald’s He has been forced to cancel a promotion: They gave cards Pokémon with his Happy Meal, but franchise collectors were presented at restaurants to buy large amounts of menus, interested in the cards and with the intention of reselling them, as collected a company statement. Then they got rid of food, which led to a “massive food waste”, only three days after the start of the campaign, on August 11. Some solutions. To solve the problem, before the definitive cancellation of the promotion, McDonald’s established a maximum of purchases per person, but the collectors raffled the ban on tail several times. The hamburger chain also asked the country’s online sale platforms that they did not accept, or at least they will limit the Pokémon cards to carry the McDonald’s seal. None of that was enough and forced the chain to suspend the promotion in record time. One Piece, again. The phenomenon It was repeatedin a very short time, with ‘One Piece’. The popular anime series was going to be subject to the next promotion of Happy Meal, but seeing what happened with Pokémon, the chain has momentarily canceled the campaign, which would have started on August 29. McDonald’s is facing a dilemma: to make toys attractive enough to sell hamburgers, but not so much to generate problems. It is not the first time. Pokémon may seem almost isolated (after all, according to experts, We talk about the object collectable more expensive in the world. But it is not the first time that this happens to McDonalds, which has already been seen in similar situations on other occasions: the K-Pop group BTSFor example, launched a menu in 2021 in 50 different countries. In some as Indonesia there were problems of minor stocks and disturbances. In 2015, on the occasion of the 50th Anniversary of the Independence of Singapore, McDonald’s launched some hello kitty dolls in limited edition, dressed in typical costumes of the country, which caused very long queues and existent problems. Finally, and leaving Asia, in the United States in 2022 McDonald’s announced a menu In collaboration with the urban clothing brand Cactus Plant Flea Marketwith four characters dressed in firm’s clothes. On the same day of the launch the menu was already exhausted. China is guilty (says Japan). There is another example of frustrated promotions that has a lot to do with it: in May of this year, McDonald’s canceled a Happy Meal promotion where they included dolls from the ‘Chikawa’ manga series. They disappeared in hours And the chain detected that it could be due to the posterior resale among collectors, in fact also observed that it was organized purchase networks. According to Some clients came to comment on social networksthey were Chinese resellers who used the orders via mobile to exceed the maximum of four orders per person that allowed McDonald’s. Many of the Happy Meals items later appeared, in effect, on China’s sale and collecting websites.

destroy a key piece of engineering

by

It is a scene that is repeated in homes throughout the country. A persistent headache, a more acute menstrual malaise than normal or muscle pain that does not yield. 400 mg ibuprofenthat usual ally of the first aid kit, does not seem to be enough, and the ‘version’ of 600 mg can only be achieved with a recipe Medical Then arises the idea of ​​leaving a tablet in two and taking 400 mg more than 200 mg that gives 600 mg. But it’s not that good idea. An idea that has had to deny a pharmacist. Through your Tiltok account, @farmaceuticofernandez, responded to a girl’s video which pointed to that an ibuprofen and a half had been taken. Its verdict is quite clear: mathematical logic is not correct. And is that the principle of the active of the medicine andStá mixed with other excipients And this is not equitably distributed in each half of the tablet, so we do not find 200 mg of medicine on each side of the pill. It is in the end a lottery. In addition, it suggests that some of these tablets have a protective film that covers it with the aim of Protect our stomach or to be absorbed in a specific place of our system. If it starts, this protection effect is lost and can generate more problem than benefit. The anatomy of a tablet. The fundamental assumption behind leaving a pill is that the medicine is distributed perfectly uniformly throughout its volume, such as dissolved sugar in coffee. The reality, however, is much more complex and looks more like a cookie with chocolate pepitas. The active substance (Ibuprofen, in this case) are the “Pepitas”, while the rest of the components, called excipients, are the “mass.” When the cookie starts in half, no one can ensure that each piece contains the same amount of chocolate. The science behind each pill. A tablet It is a pharmaceutical engineering work. In addition to the active substance, it contains a variety of excipients that are essential for its function: diluents To give volume, binders To keep it cohesive, disintegrating to dissolve in the body and lubricants such as Magnesium stearate so that the machinery does not stick during the manufacture. The most common manufacturing process, known as Wet granulationit implies mixing the API dust with the excipients and a liquid binder to form small granules. These granules dry and then compress at high pressure to form the final tablet. The ultimate goal is to ensure the uniformity of dosing units. What the box says. With this system, which is guaranteed only that each whole tablet of a lot contains the declared amount of active substance, within a margin of trust. However, this uniformity guarantee applies to tablet as a unit, and the homogeneous distribution of the active substance within each individual tablet is not ensured. And scientifically demonstrated. A study by pharmacy technicians In controlled conditions, 22 different brands of generic medicines fractioned. The results were surprising, since only 32% of the grooved tablets (designed to be games) and a little 27% of the non -grooved tablets met the uniformity criteria of the weight that are acceptable. In this way, if professionals with adequate tools cannot achieve precise division, the probability that a patient will do it at home with a kitchen knife is tiny. The slot is not decorative. If the internal structure of a tablet is a lottery, the presence or absence of a slot on its surface is the signal that indicates whether we can play or not. That small line is not a decorative element or a simple visual guide. It is a legal and scientific statement of the manufacturer that certifies that this tablet It has been designed to be split by that line To have more or less security we take a precise dose. In order for a tablet to carry a slot, the laboratory must demonstrate to the regulatory agencies that the halves meet the same standards of dose and dissolution uniformity as the entire tablet. The prospect is important to read it. This document, which we sometimes hate because once we open it you can no longer bend correctly, it indicates what we can do with the medication. If this report details that a tablet can be divided, it is because it has been demonstrated. For example, in the Paracetamol prospect From 1 gram, “the tablets are grooved, which allows to divide the tablet into equal doses.” But the same does not happen in a 400 mg ibuprofen leaflet of the Cinfa brand that is very common I even had 400 mg ibuprofen at home and I have been able to verify that I did not have any division to leave the pill in two. Something that obviously faces us to be inaccurate. The doctor has the ‘key’ to have 600 mg ibuprofen. The distinction between the 400 mg ibuprofen and the 600 mg is not just a matter of 200 mg more power; It is a regulatory and security border. In Spain, the presentation of 400 mg can be dispensed without a recipe (although often under the pharmaceutical council), while the 600 mg necessarily requires a medical prescription. This decision, taken by the AEMPS, is not arbitrary, but is based on a exhaustive analysis of the balance between benefit and risk. The issue in this case is that after comparing the effect of the 400 mg version with the 600 mg is almost the same. This phenomenon is known as analgesic “roof effect”, where major doses They do not produce additional pain in a significant way in mild cases. But what it does cause is that they increase the Side effects considerably. Something that also corroborates the pharmacist from the beginning. A suggestion effect. The problem we have in this case is the suggestion to which we are exposed. Obviously, a larger amount correlates with a greater analgesic effect according to our own logic. And this … Read more

The largest piece on Mars on Earth has just sold for 5.3 million dollars

by

A Roca from Mars which was found in the Sahara desert in November 2023 has sprayed all records in an auction in New York. A 25 -kilogram meteorite. The largest piece of Mars found on Earth already owns, and is an anonymous buyer who won the Sotheby’s auction After a bid of 4.3 million dollars. Will pay 5.3 millionif we add taxes and fees, the highest price ever paid by a meteorite. The rock, baptized as NWA 16788, weighs no less than 24.67 kilograms. With its almost 38 centimeters long, it is 70% larger than the previous largest Martian meteor. From Mars to an anonymous collector. NWA 16788 had traveled 225 million kilometers when a meteorit hunter took him in the remote region of Agadez, in Niger. It did not gently detach from Mars. He was torn from his surface due to the impact of such a violent asteroid that liquefied part of his minerals and catapulted him to space. From there, he undertook a trip of about 225 million kilometers before the earthly gravity attracted him. Its reddish cortex and depressions on its surface are the scars of its entrance through our atmosphere. It is now officially a luxury object that shows that it is possible to speculate with Martian soil. The extraterrestrial market is booming. This sale is not an isolated event, but the confirmation of an upward trend. The meteorit market is an active niche where the rarity, size and history of rocks trigger prices, but none has reached a price as high as NWA 16788. The one that was closest was the Fukang meteoritefamous for its embedded Olivino gems. In 2008, the Bonhams house tried to sell it for 2 million dollars. Pujadores preferred to invest their money in the fossilized manure of a dinosaur that was 130 million years old. In 2021, the Christie’s house sold a Martian meteorite for $ 200,000. Who knows if we will see it in a museum. The sale of such a singular meteor has revived, as expected, an old controversy in the scientific community. Many regret that a piece of incalculable value for science and dissemination can end up in a private battleship chamber. Being anonymous, the buyer’s intentions are unknown Fortunately, not all meteorite is lost to science. A reference sample has been preserved at the Purple Mountain Observatory, in China to analyze it.
