There are people reselling tickets to the World Cup final for 2.3 million dollars. Great news for FIFA

April 25, 2026 by usatoday24

It is still too early to know if the 2026 World Cup will be a success, a failure or will be added without pain or glory to the extensive chronicle of FIFA. What we can say at this point is that enjoying the tournament in situ it won’t come cheap. Especially if you aspire to see the final, which will be played on July 19 at MetLife Stadium in New Jersey. The cost of your tickets it takes months embroiled in controversy, but the debate has soured after some positions have come to light resale market for the price of a 200 m2 apartment in the center of Madrid. All with the veiled pleasure of FIFA. What has happened? That although there is still more than a month until the opening match, the World Cup in North America (to be played between Mexico, Canada and the USA) is already earning the dubious honor of being the most expensive of history. The fans screamed in the sky last decemberwhen the first tickets were launched, but the rates that were offered then seem like a ‘bargain’ when compared to those that are now being achieved in the purchase and sale market. In this secondary trade, channeled through FIFA, there are passes that are offered for the same What does a 200 m2 apartment in Madrid cost? Does it sell so expensive? Yes. The news has advanced it the Associated Press (AP) agency, but it comes with taking a look at the buying and selling platform of tickets hosted on the FIFA website to verify it. If we look for available passes for the final on July 19, we will see that there are people reselling them for more than two million dollars. To be precise, there are at least four seats on sale in the lower stand (behind the goal) for a whopping $2,299,998.85. Not all tickets cost the same, but resale prices are generally not affordable for everyone. The cheapest seats, 3rd category, are offered for $10,900. If you want a position with better views and more comfort, you can add a few thousand more to that figure and purchase higher category passes for $16,100, $33,800, $43,200 or even $207,000. The prize goes to the entries of 2.3 million and 991,500, which is what a seller asks for seats located in the front area. On Wednesday FIFA itself put up for sale a new block of tickets on its direct sales platform, where it was possible to find seats for the final by $10,990. Who controls these rates? Direct sale tickets are launched by FIFA itself, but things change when we talk about the secondary market. There, in the so-called “Resale/Exchange Market” the federation does not control prices, although it does take a considerable part of the business. For each transaction you pocket a commission which is divided into two parts. One, 15%, is applied to whoever purchases the ticket. Another, of the same value, is borne by whoever detaches from the entry for resale. As they explain in Guardianthat means that if one of the tickets that cost 2.3 million is finally sold, FIFA would deposit $690,000 into its account. But… How is that possible? In other editions of the World Cup, the resale price of tickets was limited at face value, but this time FIFA has changed the approach. The reason? First, adapt to the market of the host countries, especially the United States, which is the one will host more games of the tournament. Secondly, FIFA hopes that by channeling the buying and selling itself, the use of portals such as StubHub will be discouraged. “FIFA has established a ticketing and secondary market model that reflects standard ticket market practices for major sporting and entertainment events in host countries,” alleges in a statement cited by the Associated Press. “Resale facilitation fees are aligned with industry standards in the North American sports and entertainment sectors.” Is it an isolated controversy? The controversy has now arisen due to the prices that are being reached in resale, but the truth is that the cost of the tickets has been a matter of discussion since the first phase of sale, activated in December 2025. The focus has been on both the prices themselves and the system applied by FIFA in the sale, the ‘variable pricing’similar to dynamic rates. Consumer organizations like the OCU have already raised their voices for that same reason. For reference, in December tickets for the final were already being sold for prices ranging from 4,185 and 8,680 dollars. And this despite the initial promise to offer them for 60 dollars in the group stage. “They only exist as ridiculous green splotches on the edge of seating maps, little more than mirages of inclusion,” ironizes Bryan Armen, from Guardian. Does it only happen with tickets? No. The tickets are so expensive because, FIFA allegesare one of their main sources of income. However, passes to matches are not the only thing that is valued at a gold price. In recent days, another controversy has arisen around the celebration of the World Cup in the US that revolves around something that has little to do with sport: public transportation. The New Jersey rail operator has decided that those who want to buy round-trip tickets to travel from Manhattan to MetLife and watch the July 19 final there will have to pay 150 dollars. It is almost 11 times more than what the same service costs on a normal day, when it is around $12.9.

Who is Johny Srouji and why this great unknown has just become the second most powerful person at Apple

April 21, 2026 by usatoday24

For those who have been following Apple for a long time, Johny Srouji is no stranger. For the rest of the world yes, but after the appointment of John Ternus as CEO of Applethis Israeli engineer has become the second most powerful person in the company. The question is obvious: who is Johny Srouji? Who is Srouji and why does he matter?. Born in Haifa, Israel, in 1964 to a middle-class Christian Arab family, Srouji studied computer science at the Israel Institute of Technology (Technion) and graduated Summa Cum Laude in both his engineering and master’s degrees. He worked at Intel and IBM before Apple hired him in 2008 with a very clear assignment: to design the company’s first chips. He did much more than that. The revolution made chip. That first chip designed by Srouji was the Apple A4, which debuted in 2010 in the original iPad and the iPhone 4. From there, Srouji forged one of the most prestigious hardware careers in the recent history of the technology industry. The A7 of 2013 was the first SoC in using 64-bit architecture, and then there would come the revolution of the Apple M1 with which the company definitively got rid of dependence on Intel in its Macs. But his work goes beyond. His official title until now was senior vice president of hardware technologies, but it did not reflect the real scope of his work. Srouji not only led the chip design. Also that of batteries, cameras, storage controllers, sensors, displays, cellular modems and other critical components of the entire family of Apple devices. Almost everything that makes these products work the way they do is largely due to the work of Srouji and his team. With the new position, his responsibility expands and he will now control the entire cycle: not only the hardware itself, but also the physical design. It’s a colossal challenge, but if anyone seems prepared to take it on, it’s Srouji. He was about to leave. In December 2025 Bloombeg reported that Srouji had informed Tim Cook that he was seriously considering leave Apple in the near future. Two days later, Srouji himself published a message to his team denying the newsbut the damage was done. For Apple to lose Srouji would have been a disaster, and it is very likely that this new position is in part Apple’s response to that alarm signal. Textbook talent retention, but raised to maximum power. New position, new structure. In it internal communication that Srouji has sent to team employees, the engineer detailed how he will organize the division into five areas: Hardware engineering: led by Tom Marieb, an Intel veteran who joined Apple in 2019. Siilicio: it will be directed by Sri Santhanam, a manager with a long career at Apple Advanced Technologies: Supervised by Zongjian Chen Platform architecture: led by Tim Millet Program management: will be managed by Donny Nordhues In that message, Srouji acknowledges that this “represents a significant change” but believes it will work thanks to the entire team. It seems that you are very clear about how you want to work with your team. A fusion with a lot of historical sense. The reunification of hardware engineering and the hardware technologies division under the same leader is not entirely new. It is the structure that Apple had for years under the direction of Bob Mansfield, former head of hardware. until 2013 and? then he took charge of the failed Project TitanApple’s car. That’s when those two areas were divided, something that allowed both Ternus and Srouji to progress in their domains, but also caused some structural tensions between teams that had to collaborate. Bringing them back together is a clear commitment to strengthening that collaboration. The great cover-up of Ternus’s appointment. It is normal that the vast majority of headlines go to Ternus, who will decide the future of the company from now on, but Apple is above all a hardware company. That Srouji now becomes his leader makes this engineer a person with enormous power within the company. The change is promising in terms of promoting that facet of the product that both he and Ternus dominate, and without a doubt interesting times await us at Apple.

Science has managed to turn off the extra chromosome of Down syndrome. It has also opened the great ethical debate on gene editing

April 18, 2026 by usatoday24

In the complex genetic map that surrounds the known down syndromethe problem is not that there is a lack of information in our cells, but that there is an excess. The presence of a third copy of chromosome 21 It unbalances the entire cellular system that ends up generating an entire clinic that today did not have any type of cure. But thanks to clinical advances and revolutionary gene therapies, we have found a way to turn off this gene that is extra in the cells of people with Down. A natural switch. To understand this advance, we must look at how nature itself resolves its own genetic imbalances. And, for those who do not know, in human beings sex is determined by two types of chromosomes: X and Y. If you are a woman, you will have XX chromosomes, and if you are a man, you will have XY. The problem, boiling it down to its most basic, is that always one of the ‘X’ genes must be silenced so that the genetic load is compensated in humans. And this is something that is done thanks to the gene XIST which encodes an RNA molecule that covers the chromosome and alters its chromatin, silencing de facto their genes. Something that has been developed by nature itself in order to maintain the species, and then the question is obligatory: why not use this natural switch to silence the chromosomes that generate diseases as important as Down syndrome? It’s not something new. The idea of using this “switch” to be able to alter the gene expression of the chromosomes that we have in excess is not new, since in 2013 the researcher Jeanne Lawrence demonstrated for the first time that this RNA could induce the silencing of the extra chromosome 21 in human cells that were in culture in a laboratory. Later, in 2020, it was applied to neural stem cells, but the historical problem has always been the same: the very low efficiency when integrating this gene into the affected cells.. A new milestone. This has changed radically, as a team at Beth Israel Deaconess Medical Center in Boston has published a new article in PNAS with a solution to eradicate this bottleneck thanks to the tool CRISPR/Cas9. This system can be visualized as simple scissors that specifically cut into our DNA to eliminate something that was left over or altered. The problem is that it was not very efficient at integrating new genetic material, and to overcome this, scientists have developed a modified version of CRISPR/Cas9 that boosts the success rate of the integration of the XIST gene which will silence the third chromosome 21. Good results. Here we recognize how XIST has been integrated into 20-40% of cell lines that have trisomy 21. Furthermore, the method reliably affects only the extra copy of chromosome 21 without silencing other genes that can cause other diseases. There are problems. Despite the enthusiasm, the technique is far from being applied in humans, since one of the biggest challenges of CRISPR is the mutations off-target, That is, it acts on other genetic points that are its marked objectives. And this occurs when these ‘scissors’ cut a sequence of DNA that closely resembles its target, but which in reality is not. In this way, an error off-target It could trigger severe cellular problems or even cancer. Recent studies show that experimentation on embryos with these techniques often results in mosaicism with edited and unedited cells, as well as incomplete edits. This means that right now we have to work on having greater specificity in the genetic objectives of the therapy so that the consequences of using it are not much greater than the fact of curing a disease. Ethical shock. The controversy is served with genetic therapies in general, since right now one of the lines that are open is to eliminate this extra chromosome directly in a human embryo before implementing it in a woman so that she is not born with this disease. This is where bioethicists they point because experimenting with human embryos damages their physical integrity and poses irreversible risks for future generations. Furthermore, they underline the urgency of distinguishing between the use of CRISPR for purely therapeutic purposes, such as treating symptoms, and its use for “genetic improvement” or the selection of embryos that are much more advanced or genetically perfect. This is also added to the fact that genetic editing in embryos for reproductive purposes is currently prohibited in most countries.

The Seville Fair is growing so much that it is no longer just the great macro event in Andalusia: it is the ‘Coachella castiza’

April 15, 2026 by usatoday24

The Seville Fair wants to grow. And it is understandable. A year ago, when he announced his plans to tug to the fairgrounds, the mayor of Seville already warned that although right now the quote adds up to around a thousand booths There are many other applications waiting. Added to this enormous demand is the tourist success of the event, its ability to attract thousands and thousands of visitors and its economic potential, which translates into a trickle of million euros. There is, however, an even greater merit than Seville can boast: its fair is emerging as the largest macro event of Andalusia, a sort of traditional Coachella that grows while other fairs in the region stagnate or even decay. A ‘pure Coachella’? Yeah. The expression may seem shocking, but saving the obvious distances between the Californian event and the one in Seville, the truth is that both events share some parallels. The first and most obvious are the dates. The second. that both one and the other have become macro events referential, capable of attracting thousands of visitorsgenerate a millionaire business and above all overshadow other quotes of a similar nature. In a way, it also confirms a trend that has been taking shape in a more or less diffuse way in recent years: the festival calendar is polarizing between massive events, such as the April Fair in Seville, capable of attracting crowds and, above all, being promoted thanks to the tourismand others micro events with a much more modest, specialized and local approach. Between both categories there is an increasingly eclipsed dating ‘middle class’. Question of fairs and magnetism. Andalusia leaves a good example of the above. Although many more fairs are held in the region, such as Our Lady of Health in Córdoba (May), the Sherry horse (May), the Corpus Christi of Granada (June), the Malaga fair (August) or Saint Luke of Jaén (October), the one in Seville is probably the one that has achieved the greatest impact. And that is something that can be measured in two ways: through social networks, where it has become an viral phenomenonand in figures of both attendance and business generated. To confirm the first comes with taking a walk through Instagram or TikTok, where the fair has been gaining weight converted into a unifying and touristic event. Beyond the party, for Sevillians it is an opportunity to show their national pride. For those who live far from their cultural code, especially for visitors, it is an exotic event. Question of figures. Regarding the second, the figures are overwhelming. Last year the Seville City Council estimated in 2 billion of euros the economic impact of the fair, a figure largely justified by the high hotel occupancy (and the average price of accommodation) that Seville reaches on those days. Some sources slide This calculation also includes Holy Week, which is celebrated shortly before, but even so the figure is more than considerable. Regarding the volume of visitors, in the last few years The influx at Real de Los Remedios, the place where the fair is held, has been estimated at three million of people. As a reference, in Malaga they calculate that the shows at their fair attracted around 966,000 visitors. The event is in fact so attractive that in Madrid they have already promoted an initiative to organize its own April Fair, a macro event which aims to attract around 800,000 visitors. Fairs that grow… and fall. Aside from the visitor balances, hotel occupancy or business estimates, there is an interesting fact to understand the thrust of the Sevillian fair. Last year the City Council confirmed his plans to give it a ‘growth spurt’, providing the Real de la Feria with new streets and 220 extra booths. The reason? “Currently there are almost a thousand booths and there are another thousand applications from people waiting,” explained the first mayor, José Luis Sanz. The Seville City Council is so determined to undertake the expansion that the project has even caused a little crisis with the Government, owner of the land. The scenario contrasts with that experienced, for example, by the Córdoba Fair, which this year will feature 82 booths. This is relevant information because, as remember theDiaryare four less than in 2025 and mark a historical minimum for the event. New proof that the calendar is increasingly divided between celebrations supported by tourism and others with a more local focus.

the great waste management fraud

April 15, 2026 by usatoday24

In the early 1980s, some North American cities began to realize that the waste generated by plastic was enormous and uncontrollable. Technicians and activists began to talk about regulations and prohibitions, but the industry found another way to solve it: recycling. The standard. For 50 years, the petrochemical industry has promoted recycling as the ‘gold standard’ for solving plastic pollution. Today, We know that only 9% of all plastic produced historically has been recycled. It was not a miscalculationnor a display of naive optimism: it was a large-scale industrial fraud. A documented fraud. In 1973, ahead of the regulatory wave, the Society of the Plastics Industry commissioned a report to see what could be done with the plastic they made themselves. The study’s conclusions were devastating: not only did it recognize the inherent degradation of resins in each reprocessing cycle, but it made clear that (even in the best of cases) there was no market for the final product. And, of course, the industry didn’t care. A report from the Center for Climate Integrity and the summary of a macro-case by the California attorney general against ExxonMobil give us the keys to understand it. Because it’s not exactly a secret. An Exxon employee recognized in 1994 before the American Plastics Council that “the company was committed to recycling activities, but not to their results.” The founder of the Vinyl Institute (one of the sector’s lobbies) admitted in 1989 that recycling could not be continued indefinitely and that, of course, it did not solve the problem of solid waste. We have proof. What’s more, for decades, we have known that there are internal documents that show patterns of investments in recycling plants that were closed or abandoned once they had fulfilled their public relations function. The tests go on and on. However, no one paid much attention. The parallelism with climate denialism ands patent: the documentation is crystal clear. The industry knew recycling wouldn’t work, but spent millions and millions actively promoting it with the idea of avoiding regulations. And why is it news now? Because there are doubts that this is over. Yes, the average citizen has internalized that separating waste and depositing it in the yellow container (or the equivalent system) is an effective environmental action. In fact, the better the citizen recycles, the more effective the industry’s alibi is to continue producing plastic without restrictions. Recycling actually displaces regulatory pressure. Because the data (and recycling rates whatever the approach) is not as good as we might think. And the problem is volume. Plastic production is going at such a speed that even by significantly improving recycling rates we would not be able to reduce the amount of plastic that ends up in the environment. And what do we do? That’s the big question: what do we do. Our society has become so dependent on plastic that the most effective solutions are outside the realm of possibility. But if the situation continues like thisthey will stop being so sooner rather than later. Image | Nick Fewings In Xataka | We have known for years that our recycling system is broken. It seems that we are finally going to fix it

Ten years ago, Bnext was the great hope of fintech. They ended up crashing

April 14, 2026 by usatoday24

Founded in 2016 by Guillermo Vicandi, Bnext It was born as a fintech alternative to traditional banking. In fact, their visible heads assured that it was not a bank, despite offering an account and card. The growth was as fast as the fall. After the collapse of its cryptocurrency, The app announced its closure on April 13. What was Bnext. It was not a bank, that’s what its creators constantly said. It was an electronic money entity (EDE) alternative to traditional banking. In practice, it offered what a bank offers: account, card, loans, insurance, currency purchases, investment plans. The difference was the model: Bnext always acted as an intermediary, connecting the user with the best products on the market through a single app. No offices, no paper, no queues. The golden age. In 2019, Bnext was one of the most visible projects on the Spanish fintech scene. became the fintech that grew the most in Spainwith more than 156,000 registered users and more than 100,000 active clients holding a Bnext VISA. Your second round of financing It closed with 22 million eurosthe highest figure seen in Spain (in 2019) since the Valencian Hawkers raised 55 million euros. That same year, they partnered with giants like MyInvestor to offer financial products. The stumble. Bnext’s first setback comes a year later, in 2021, after its landing in Latin America. Its partner, Cacao Paycard, did not obtain authorization to operate from the National Banking and Securities Commission (CNBV), which translated into a fine of 2.6 million Mexican pesos (about 150,000 euros at the current exchange rate) to Bnext for misleading communication. There was no plan B. Bnext had to cease operations in Mexico, close all its accounts and lose more than 230,000 clients who had trusted the company prior to the sanctions. Meanwhile. In Spain, alternatives like Revolut were growing like wildfire, and Bnext was beginning to run out of oxygen. In 2021, they decided to ally with Algorand, a blockchain firm that became one of the company’s main shareholders. After the alliance they announced their own token: B3X. The play didn’t go well. On March 1, 2022, it was launched to the public with a starting price of two euro cents. Today it cannot even operate from the app, since the service has been dismantled. Its price before the debacle: 0.00006 US cents. What happens to Bnext users. Bnext accounts and cards have already been canceled and the product is no longer marketed. No payments, transfers or receipts can be uploaded. Payroll cannot be received The balance of the account may be requested during a repayment period of 20 years Cryptocurrency management is referred to Onyze… via email User data will be deleted in accordance with the GDPR You will no longer have access to the marketplace services Bnext was once the great hope of Spanish fintech. Now rest in peace. What will become of the company. The company gives the finishing touch to its app, but does not completely cease its operations. “The fintech business and market has changed considerably, and with this, we have had to pivot our value proposition. After several years offering products to the end consumer and in an increasingly competitive environment and with more complex regulation, we have decided to take a step towards the future, focusing on helping companies launch their own payment products.” Guillermo Vicandi, CEO of Bnext. Bnext closes as a neobank, but pivots towards financial infrastructure services. In Xataka | Europe had been asking for a big hit on the table for some time. Revolut just gave it a huge valuation

If the question is why men don’t wear skirts, the answer lies in the 18th century: the Great Male Renunciation

April 12, 2026 by usatoday24

We have it so internalized, so assimilated, that perhaps you have never thought about it, but here goes one of those questions that sound like a truism: Why do men and women dress differently? Why is it that when we go to a wedding, a gala or an elegant dinner, it is taken for granted that they will wear a more or less sober suit and discreet colors while they will wear dresses and heels? Why are ‘men’s’ clothes usually more functional than women’s clothes? And already, why don’t we wear skirts, like was wondering recently David Uclés? As is usually the case when we talk about fashion (social trends in general), none of the above is the result of chance or simple whim. Why do you dress the way you dress? Things as they are: if you are a man (at least in the Spain of 2026) and you go to a meeting in a dress and heels, it is quite likely that your colleagues will be surprised to see you cross the door. However, the same clothing on a woman would be considered very normal. Because? That same question was recently asked by the writer David Uclés. And it’s not the first. Before him, others had already slipped it, such as the designer and photographer Ana Locking, who in another recent interview on the SER network encouraged men to be much more risky when selecting their wardrobe. “If you want to feel sexy today, dress sexy. The boys’ legs are super sexy, the boys’ necklines are super sexy. Open your neckline, wear a skirt, some shorts, some ankle boots with a little heel,” encouraged Locking after lamenting that, as they mature, men “clip their wings” when they confront the closet. “What they will say comes into play a little bit, feeling vulnerable.” Is it just social pressure? It depends how you look at it. Fashion in itself is a social construct, but the tendency that leads us men to opt for sober clothing and banish skirts, heels and clothing that may be considered ‘extravagant’ from our wardrobes is explained by another reason: the story. In fact, it is not a guideline that has always been applied. Come take a walk through the Costume Museum or El Prado to prove that when it comes to men’s fashion, sobriety has not always been synonymous with good style or elegance. For example, this canvas of King Philip V with his family painted in 1743 by Louis Michel van Loo or this other work from the end of the 17th century, also preserved in El Prado, and in which Jacob-Ferdinand Voet shows us Luis Francisco de la Cerda, IX Duke of Medinaceli. Is there anything that catches your attention about them? Wigs, high heels and brilli brilli? Exact. If you look at both works you will see that the men wear wigs, heels, stockings, loose jackets that fall almost like skirts, and an abundance of bright colors, the kind of clothing that at that time (late 17th century, first half of the 18th century) denoted status. If you think about it it makes sense. What they show us Jacob-Ferdinand Voet and Louis Michel van Loo They are characters dressed in colorful outfits, although they are not what we would say ‘functional’. But… Why should they be? If anyone could afford that kind of clothing it was aristocrats who didn’t have to work. Who doesn’t like heels? William Kremer explained it well in 2013 on the BBC when reviewing The history of high heels and why men stopped wearing them. Again, it may sound like a far-fetched question, but it actually makes a lot of sense and reveals even more about our history. For centuries heels were worn in the Middle East as part of horse riding clothing. And not only for aesthetic reasons. With them Persian soldiers could stand on the styles, stabilize themselves and adopt a good posture to use the bow. When at the end of the 16th century sha Abbas I of Persia He sent a diplomatic mission to Europe to gather support. The nobles noticed the Persian-style shoe. They liked it so much that over time they began to wear high heels that highlighted their size… and their social rank. And all that with heels? That’s how it is. “One of the best ways to convey status is through the impractical,” commented in 2013 Elizabeth Semmelhack, of the Bata Footwear MuseumToronto. Perhaps heels were not very advisable for walking through the countryside and the paved and potholed streets of the 17th century cities, but did the same nobles who posed for chamber painters dressed in clothes as luxurious as they were cumbersome have to do so? “They don’t work in the fields nor do they have to walk a lot.” Why did they stop being used? Times have changed. And the way of thinking. When they review the history of fashion (especially men’s fashion) historians usually stop at the Enlightenment, between the mid-17th century and the beginning of the 19th century, a time in which intellectuals opted for a way of thinking in which what was rational and useful was prioritized. Also education about privileges. Status is no longer an inherited gift, but the result of training and work. As far as fashion is concerned, this translated into a new sensitivity that favored the use of garments comfortable and functional. In England, for example, even landowners ended up embracing a more practical style, better suited to managing their properties. At least that’s how it was among men. The rational aspect stood out among them; The emotional nature was highlighted in them. Did only the Enlightenment influence? No. The Enlightenment mentality played a crucial role, but historians usually point out an episode that (although inspired by the Enlightenment) is much more specific, both geographically and temporally: the french revolution. Against this backdrop, the way one dressed became more than a simple aesthetic choice or a mark of status. … Read more

Plastic is the great recycling nightmare. Car battery acid aspires to be the great nightmare of plastic

April 11, 2026 by usatoday24

Have a problem with recycling. Thus, in general and even in countries that the more they try and complicate things. But, specifically, we have a problem with plastic recycling. It is a difficult and therefore expensive process, rather than producing new plastic, which leads to a scenario in which potential waste accumulates. To complicate things further, there are many types of plasticsand some are terribly difficult to recycle. But the University of Cambridge has had an idea: a solar reactor to destroy those difficult plastics. And the secret ingredient is car battery acid. The data. Before entering the ‘invention‘ from Cambridge, let’s go with some context. Recycling is not collecting, and vice versa. An example of this is Japan, a country in which there are areas in which there are 45 different categories of garbage that citizens must separate and where only 20% is recycled. In Spain, with an infinitely less obsessive systemwe are around 39%. And what is not recycled is burned in Japan and sent to landfills in Spain. Focusing on plastic and according to Cambridge researchers, the world produces 400 million tons per year and only 18% is recycled. And, as I say, there are plastics such as nylon or polyurethane that are particularly complex to recycle because their chemical structure is very resistant, which makes breaking them down complex and very expensive. plastic fulminator. This is where the discovery of the University of Cambridge comes into play. What they have developed is a solar-powered reactor that uses a very special ingredient: car battery acid. This component breaks the structural chains of the polymers into more basic chemical blocks and, therefore, easier to assimilate, such as ethylene glycol. Once the new material is obtained, a very special photocatalyst is what allows it to be converted into hydrogen and acetic acid, putting an end to that ‘rebellious’ plastic. By fluke. The team of researchers comments that the discovery was practically an accident since they knew that battery acid could be used for the process, but it was not convenient because, just as it melts plastics, it ‘eats’ the catalysts. Theirs, however, held out, and it turns out to be cheap and scalable. It is a photocatalyst composed of carbon nitride functionalized with cyanamide and integrated with molybdenum disulfide promoted with cobalt. Lots of text to say that it is a hybrid material specifically designed to remain stable in a strongly acidic environment. According to the team, it is economical and solves two problems at once: it dissolves difficult plastics and reuses battery acid that usually ends up as waste after extracting its lead content for resale. Future. In the tests, the team points out that the system has worked for more than 260 hours without losing performance and works with the aforementioned plastics, but also with that of the plastic bottles They are also not particularly easy to deal with. They claim that their discovery offers a potential cost reduction in recycling tasks because, in addition, reusable hydrogen is produced in the process. The key here is finding a way to collect the battery acid before it is neutralized for uninterrupted use to break down plastics. The team comments that they do not promise to solve the problem, but they demonstrate how waste can become a resource. new life. This approach approaches the problem from the angle of decomposition, but there are other proposals to give these plastics a second life. Because ‘melting’ them may be expensive, but if they are put into presses they can be turned directly into bricks or paving stones for the streets. This is what Nzambi Matee proposes, a Kenyan materials engineer who has proposed convert that waste into construction material. Like the University of Cambridge experiment, it addresses two problems at the same time: recycling and creating necessary non-polluting construction elements, and this idea is catching on because the authorities have given the green light to use this 2.0 brick to pave the streets of Nairobi. Returning to battery acid, the business arm of the University of Cambridge is looking to commercialize the company, but now the most complicated thing remains: making it a standard.

DeepSeek promised them happiness as the great Chinese AI. I didn’t count on a small detail: Kimi

April 7, 2026 by usatoday24

Just a year ago, DeepSeek was one of the biggest scares that Silicon Valley had received dwarves. A Chinese model trained with a fraction of OpenAI’s budget equal to GPT-4 in benchmarks. Upon its arrival the message seemed clear: Western dominance of AI had its days numbered. Today, the story stands, but not thanks to DeepSeek. The DeepSeek case. DeepSeek carries months late for its V4 and, to date, has already lost three of the authors of R1, the model that catapulted them to success. The monthly downloads fell 72% in the second quarter of the year, seeing how Doubao (ByteDanec) snatched the lead. With missed dates, usage errors due to cyber attacksand the difficulty of split from NVIDIA To bet almost entirely on Huawei’s Ascend chips, Chinese alternatives like Kimi have been gaining ground. Meanwhile, on the other side of China. Moonshot AI was not born surrounded by noise like DeepSeek. It was founded in March 2023 by three former colleagues from Tsinghua University: Yang Zhilin—PhD from Carnegie Mellon, former Google Brain and Meta AI—, along with Zhou Xinyu and Wu Yuxin. There were no visible or media faces behind it, only product. That product is Kimi, and in early January 2026 the company launched it in its K2.5 version. In code and video benchmarks managed to surpass GPT-5 and Gemini Pro 3with the key to Chinese AI: its API costs between 4 and 17 times less than OpenAI’s. Those responsible for Moonshot explained how Kimi was almost at Claude’s level in software development testing, encouraging the race for open models. The money arrived. The commercial results are what really attract attention. In less than 20 days Following the launch of K2.5, Kimi’s cumulative revenue exceeded everything billed during 2025. API’s international revenue increased fourfold since November of the previous year. The consequence in valuation has been dizzying: 4.3 billion dollars in December 2025, 10 billion in February 2026, 18 billion in March. Three months, valuation multiplied by four. Kimi has thus become the fastest decacorn in Chinese business history. The Chinese maelstrom. DeepSeek was born a year ago as the great revolution that questioned the closed model of Silicon Valley. It only took a few months for Moonshot to steal the limelight and manage to be on par with – or even above – giants like Google and OpenAI in the most used models in the world. In favor of DeepSeek, it should be noted that its objective is different: it does not follow the typical startup pattern with pressure for immediate monetization and it is a gigantic AI laboratory that can afford not to win in the short term.
