the sensation of jumping from the 13th floor at 100 km/h

by

With summer almost (almost) knocking on the door, it’s time to think about what to do on vacation and how to take advantage of the sun, the heat and the long days that provide light until late in the afternoon. There are those who choose the beach, the mountains, a cold beer on a terrace or, in the case of people hooked on adrenaline shots, jumping into the void from 13 stories high, without ropes or parachutes. It sounds strange, I know, but that’s precisely it. the experience featuring Verti-Go, one of the tallest water slides in Europe. Its owners assure that when descending it they are easily reached. 100 km/h. As I said: an experience suitable only for people who really like adrenaline. Who said vertigo? Spain offers many ways to cool off in summer, but few (none) like Vertigohe megaslide aquatic Aqualandia Benidorma huge water park located on the Costa Blanca. Whoever gets on it is guaranteed a dip, but first must face an experience that is not very advisable for people with vertigo or those who do not like strong emotions. Before reaching the water you must climb several dozen meters and then drop into the void and travel, in a matter of three seconds, the equivalent of a multi-story residential tower. “It’s like jumping off a 13-story building,” they assure those responsible for the park, who specify that the level of inclination exceeds 60%. Is it that big? Yes. And it comes with taking a look at your file to check it. According to Aqualandia Benidorm, the slide is 33 meters high and more than 100 m long, allowing those who slide down it to reach more than considerable speeds. Those responsible speak of more than 100 km/halthough they clarify that this information depends, among other things, on the body mass of the person jumping. To enjoy the experience you must meet certain conditions: measure at least 1.4 m and not exceed 120 kg. If you want to release adrenaline, but with a somewhat more moderate experience, the same park has a second water slide 28 meters which extends over 95 m in length. It is a smaller version located right next to its ‘big brother’, although it still far surpasses the majority of water slides in Spain. Is it new? No. Verti-Go was introduced to the world a few years ago, during summer 2013. At that time it was announced with great fanfare as one of the riskiest (and most attractive) bets of Aqualandia, a water park that also accumulates a long story. The venue opened its doors in 1985presenting itself as “the largest in Europe”, with a dozen attractions. from the park they explain which maintained that status for just over two decades, until 2008. That year opened in Tenerife Siam Park. If Verti-Go is in the news these days it is because Aqualandia has just premiered its new season. It did so on Saturday the 23rd, with more than twenty attractions that include rapids, soft slopes, a wave pool, several slides, Verti-Go, children’s areas and another highlight: Cycloneinaugurated in 2019 and, depending on the park“holds the record for the longest water roller coaster in Europe.” The truth is that it reaches a greater height than Verti-Go (36 m) and travels more than 200 m, although the average speed is much lower (60 km/h). @aqualandiabnd And if you then end up in a capsule that launches you at 100 km/h from a height of 33 meters… I won’t even tell you. 😏 Raise your hands 🙋 those who have already experienced the Verti-Go madness. 🔥 #vertigo #waterslide #giantslide #capsuleslide #aqualandia #waterpark #waterpark #waterpark #benidorm ♬ Vidrado Em Você – Dj Guuga & Mc Livinho Do you have any Verti-Go records? If you search on Google you will find a good handful of articles in which Verti-Go is referred to as “the water slide highest in Europe” or the “capsule slide fastest in the world“. The reality is more complicated. When it opened, in 2013, showed up as a unique case and the largest attraction of its kind on the entire continent. The truth is that for years in Caribe Baya park in Veneto (Italy), there is a water slide that allows you to jump from a height of 42 m. His name: Captain Spacemaker. According to the Italian venue, it is “highest in Europe” in his style. If we look further we find facilities still most surprising. In Meryal Park in Qatar, there is a slide that “reaches a height of 76.3 m.” Its name leaves little room for doubt: Vertigo. In Brazil there is also another mass to take into account, Kilimanjaro, built more than 20 years ago and offering a drop of 49.9 m. According to the Guinness Book it is “the tallest water slide”. Have they overcome it then? If we talk about water slides, Vertigo or Kilimanjaro are much higher than Verti-Go, but if we talk about Europe things are a little more complicated. The rankings They usually place the Caribe Bay structure in Italy first, because exceeds 40 meters in height. However, some media indicate that the complete structure of Verti-Go is also around those dimensions. Aqualandia itself assured in 2016 that the attraction has a 42m high. Are there more categories? Yes. The Alicante park also boasts that Verti-Go is a unique copy “capsule slide”, a label that identifies a very specific type of slide. Basically, users enter a capsule with a trapdoor in the floor that, after a brief countdown, opens to let them fall. In 2016 Aqualandia claimed that Verti-Go was “the tallest in the world.” Now keep defending which, at the very least, is “one of the tallest capsule slides.” “Only the bravest dare with this attraction suspended on a 42 m high platform, where the tower has 250 steps to its highest point, simulating the height of a 13th floor and which is accessed through an airtight and transparent capsule,” clarify the company. … Read more

the IMEC chip laboratory has manufactured the first qubit with ASML’s High-NA machine

by

Manufacture a qubit, the physical device that implements the minimum unit of information in the quantum computersit is not at all a piece of cake. There are several types: superconductors, ion traps, neutral atoms or ions implanted in macromolecules, among other variants. Not all of them are equally complexbut all are difficult to produce and manipulate. In fact, the ideal is to be able to manufacture them on a large scale in order to make possible the arrival of quantum machines equipped with many more qubits than the current ones. The first step in this direction was taken by Intel and QuTech, the research institute specialized in quantum computing that belongs to the Technical University of Delft, in the Netherlands. At the end of March 2024 they announced that they had managed to produce the first qubit industrially and using the same processes and technology that is currently used for manufacture semiconductors. However, it is now IMEC (Interuniversity Microelectronics Center), the most experienced laboratory in the development of new integration and nanotechnology technologies that we have in Europe, which has signed a very important milestone: has managed to manufacture a qubit using extreme ultraviolet (UVE) and high aperture (High-NA) photolithography equipment from ASML. Currently this is integrated circuit manufacturing machine most advanced that exists. Caressing the dream of industrial manufacturing of qubits for quantum machines IMEC’s ​​main laboratory resides in Leuven, Belgium and has collaborated closely with ASML for more than four decades. Thanks to this collaboration you have access to the most advanced lithography equipment of the Netherlands company. The qubit produced using ASML’s High-NA equipment is a silicon quantum dot spin type. These qubits are very interesting because they are considered the most promising candidates for industrial scaling. In fact, as IMEC assuresthey are known as “the qubits of industry.” IMEC has shown that the manufacturing of these qubits is largely compatible with the production of CMOS chips The really relevant news is that IMEC has demonstrated that the manufacturing of these qubits is largely compatible with the production of integrated circuits using CMOS technology (Complementary Metal-Oxide-Semiconductor or complementary metal oxide semiconductor). And therefore it is possible manufacture them in conventional semiconductor plants. An important note: CMOS is the transistor manufacturing technology behind virtually all modern chips. Sofie Beyne, the director of this project at IMEC, maintains that “We can leverage decades of semiconductor innovation and repurpose the entire silicon scale-up ecosystem, taking quantum devices beyond laboratory experiments into large-scale, fabricatable systems. This is where silicon-based qubits have a clear advantage.” Experts who research in the field of quantum computing they are convinced that having machines with millions of qubits will lead to the arrival of error correction technology, which is the holy grail of these computers. Broadly speaking, silicon quantum dot spin qubits confine an electron within a silicon nanostructure, so that the spin state of the trapped electron is used to store quantum information. This architecture requires that the spaces between the different doors be minimal in order to reduce environmental noise and minimize errors. Be that as it may, what is really important is that IMEC has managed to manufacture a network of qubits with spaces of just 6 nm. Thanks to the nanoscale of this component, millions of qubits could theoretically be integrated into a single chip.

China has more solid-state battery patents than anyone else and still fears being left behind for one reason: Japan

by

What China is leading the energy and mobility transition What we are witnessing does not take anyone by surprise at this point. However, not all fish are sold, and in energy storage we are going to witness a significant evolution with the arrival of solid state batteriesa type of battery that we have been talking about for years. Just like they count From CarNewsChina, the country dominates the volume of research and records on solid-state batteries, but be careful because that leadership on paper does not guarantee winning the commercial race. And it is that a new analysis of the Xinhua agency recognizes that the United States, Europe, Japan and South Korea are moving forward with more industrial coordination and better international deployment of patents, just when the technology enters a decisive phase for its commercialization. Why it matters. Solid-state batteries are considered the next big leap from current lithium-ion batteries. These promise more energy density, faster charges, greater security and longer lifespan. They not only affect the electric car, but also humanoid robotseVTOL (vertical take-off aircraft), consumer electronics and stationary storage. Basically, whoever controls the technology and, above all, its manufacturing at scale, will set the pace of mobility and energy in the next decade. Patent war. China accounts for around 35% of the world market for solid-state patents and 39% of those related to electrolytes, the largest global share, according to share from CarNewsChina. Scientific publications have gone from 21 articles in 2015 to 562 in 2023, with institutions such as the Chinese Academy of Sciences or Tsinghua University leading advances in the engineering of the solid-solid interface, which for years has been one of the great bottlenecks. On the other hand, Japan continues to be the leading technological source with about 37% of global requests, compared to 30% from China. Japan is ahead. The problem in China is not quantity, but the concentration and quality of your strategy. Among the 30 most relevant institutions in the world in solid state and electrolyte patents, 17 are Japanese7 Chinese, 5 South Korean and only 1 European. The top ten positions are entirely Japanese or Korean. Toyota, alone, accumulates around 40% of all intellectual property in the sector. Added to this is a structural weakness, since Chinese companies register many fewer international patents than their Japanese and South Korean rivals, who shield their technology in the United States, Europe, India and Southeast Asia. The companies that move the board. CATL, BYD and SVOLT are leading the latest phase of this technology. And only in 2023 will Chinese companies filed more than 500 patent applications. Gotion High-tech The design of a 2 GWh line for totally solid batteries has already been finalized and another 0.2 GWh pilot line is operating with tests on vehicles. Ganfeng Lithium, backed by Changan, claims to have reached 1,100 cycles in a 400 Wh/kg cell and aims for 500 Wh/kg in production. On the other hand, Chinese researchers have also shown a prototype of 451.5 Wh/kg capable of charging in three minutes. CATL, for its part, is patenting lithium compounds with fluorine and sulfur electrolytes to improve fast charging and thermal stability. Deadlines. own report Xinhua places the start of production in small series around 2027 and broader commercialization around 2030. The industry continues to work in parallel on three electrolyte routes (sulfide, oxide and polymer) without any having won yet. Furthermore, according to the media, there are still challenges to overcome, including the formation of lithium dendrites, ionic transport mechanisms, solid-solid interface engineering or cell failure modes. And now what. China is preparing to industrialize what it currently masters in the laboratory. And its first national standard on solid state batteries (“Terms and Classification”) is under public consultation and proposes to differentiate between liquid, solid-liquid hybrid and totally solid cells. For now, the country dominates in terms of volume of papers and research, but it is clear that real dominance will come from manufacturers who first resolve large-scale production, cost, durability and safety. And let’s be honest, China has an advantage, especially with CATL and BYD controlling much of the world’s battery sharebut in the field of solid-state batteries there is still play.

There is a new wave of startups creating new AI millionaires

by

The rise of AI has generated a new hypermillionaire saga who are breaking all limits of wealth to date. All you have to do is go through the list of 10 of the greatest fortunes in the world of Forbes to discover that eight of these great assets arise from this technology. However, this was only what Bloomberg called “the first wave”, in which the founders of the great generalist AI models such as OpenAI have risen. Anthropic either deepseek. Now is the time for specialized AI agents and their founders they are also getting rich. The 19 new barons of AI. As and as I pointed out BloombergAmerican AI startups have created 19 new billionaires in the last year with a combined fortune estimated at about $59.3 billion. These 19 new millionaires join the 41 founders who, thanks to the success of their AI models they had already become millionaires in the “first wave.” However, what is striking about this increase is not only the number, but the profiles of who are behind these million-dollar startups: a poet, three scholarship recipients from the Peter Thiel program without a university degree or a self-taught immigrant. AI agents are the new oil. Reflection AI It is one of the most obvious cases of this new wave of AI millionaires. The startup is dedicated to creating agents capable of programming, debugging and understanding code almost independently. This new market It has turned its founders into millionaires. It is estimated that Ioannis Antonoglou and Misha Laskin have achieved a fortune valued at around $4 billion each. However, the company did not emerge from nowhere, Antonoglou was part of the team that developed AlphaGo, from the revolutionary Google DeepMind model that achieved beat humans at Go. An AI wants to be your lawyer and your doctor. Without leaving aside AI agents, Harvey is another success story in this segment, allowing the automation of legal research, the drafting of legal documents and the review of contracts with AI. Founded by lawyer Winston Weinberg and AI researcher Gabe Pereyra while they shared a flat, its AI agent Harvey, named after the protagonist of the popular lawyer series Suits, has become one of the most used in companies and law firms. Each of its founders is the owner of an estimated fortune of 1.6 billion. In the healthcare field, OpenEvidence has followed a similar path. Its founder, Daniel Nadler, already sold the financial analysis platform Kensho to S&P Global in 2018 for $550 million. With OpenEvidence, it applied the same logic to the medical sector: its AI assistant has accumulated more than 100 million consultations and the company has almost quadrupled its valuation in six months to reach 12 billion, raising Nadler’s assets to 7.2 billion dollars at the beginning of 2026. The Thiel Fellows: from recruitment to labeling. Mercor is another example that was difficult to imagine just a few years ago. Their three foundersBrendan Foody, Adarsh ​​Hiremath and Surya Midha, met at a high school debate. The three classmates left the university to join the Thiel Scholarshipthe PayPal co-founder’s program that pays $250,000 to young people to leave their studies and start a company. Initially it was a recruiting platform, but they switched to data labeling providers for OpenAI and Anthropic, hiring doctors, engineers and scriptwriters to train AI models specialized in these areas. As a result of this change, Mercor went from earning 100 million in 2025 to 1,000 million at the beginning of 2026, with a valuation of 10 billion. That leaves each of the founders with an estimated fortune of $1.9 billion. The ecosystem versus the giants. Vercel is another example of how the startups that are succeeding in this second wave of unicorns emerged from AI. We are no longer talking about AI models, but about the infrastructure that allows deploying applications generated with AI. Its founder, Guillermo Rauchimmigrant Argentinian and self-taught who learned English by reading software manuals to learn how to program, turned a tool for developers into a very profitable platform that has given him an estimated fortune of more than 1.9 billion dollars In Xataka | We already know who has won the AI ​​race: the OpenAI employees who sold their shares Image | Brendan Foody

The greatest Japanese military taboo after the Second World War has just been blown up. China and North Korea are to blame

by

In 1945, Japan emerged from World War II with a new Constitution that, in practice, prevented him have again offensive aircraft carrier. Eight decades later, one of its largest ships is once again preparing to operate fighter jets from the deck alongside the US Marines. Japan leaves its historical limits behind. Japan is entering a military phase that for decades avoided describing openly. He “Kaga”officially classified as a helicopter destroyer, will operate in June F-35B stealth fighters of the US Marine Corps in joint exercises that definitively bring the country closer to a light aircraft carrier capability. The gesture is much more important than it seems because it breaks a deeply rooted political and historical barrier since World War II: the idea that Japan should strictly limit its offensive capabilities. Tokyo continues to avoid the term “aircraft carrier,” but operational reality is beginning to look more and more like classic shipborne aviation. The Kaga and a return. The transformation of the “Kaga” and its twin “Izumo” It has been underway for years, but now it is entering the truly decisive phase: operate fighter aircraft fifth generation from deck in real conditions. The planned exercises with the US F-35B will include “cross-deck” maneuvers, where Marine aircraft take off and land from a Japanese ship. all this requires modifications depth in the deck, thermal resistance to withstand vertical landings and new coordinated procedures between pilots, sailors and technical personnel. Although Japan has placed the F-35Bs under the control of its Air Force and not the Navy, the practice brings the country enormously closer to having fully functional small aircraft carriers. A US Marine Corps F-35B lands aboard Kaga during training exercises in 2024 China and North Korea behind. The great driver of this transformation is the deterioration of the strategic environment in the Indo-Pacific. China multiply your pressure naval around Taiwan and the East China Sea as North Korea maintains a constant capacity of military destabilization. In this context, Tokyo needs to disperse its air capacity and reduce dependence on vulnerable ground bases. There the F-35B enters: a fighter capable of taking off over very short distances or landing vertically from relatively small decks. For Japan, this offers enormous flexibility in an archipelago full of islands and long sea distances. Each converted ship expands the number of platforms from which the country can project air power. USA as accelerator. The direct involvement of the US Marine Corps makes clear the extent to which Washington is acting as an accelerator of Japanese military transformation. The Marines already made the first historic landings on the “Izumo” in 2021 and since then they have accompanied practically all phases of the program. The “Kaga” even traveled to the United States for specific tests with F-35B and has already operated alongside British and American aircraft linked to the aircraft carrier HMS Prince of Wales. More than simple maneuvers, these exercises serve to integrate allied doctrines, logistics and procedures in a possible regional crisis scenario. The Indo-Pacific is filling up. The change also reflects a broader trend: the proliferation light aircraft carrier and ships capable of operating F-35Bs throughout the US allied network. United Kingdom, Italy, South Korea and potentially Spain sfollow similar paths to maintain embarked aviation without the need for gigantic nuclear supercarriers. He F-35B It has thus become the centerpiece of a new generation of medium navies capable of projecting air power from relatively compact platforms. Japan fits that model perfectly, especially in a scenario where war in the Pacific could force aircraft, ammunition and fuel to be dispersed across multiple moving points. The real test begins now. Until now, much of the Japanese program had still been experimental or symbolic. The real test begins with regular operations, long deployments and the ability to sustain stealth fighters on deck for weeks. That is where it will be measured if the “Kaga” It definitively ceases to be a “helicopter destroyer” to become, in practice, a a light aircraft carrier fully operational. And there, too, the most profound change is perceived: Japan is gradually leaving behind the defensive military culture to adapt to an increasingly Indo-Pacific more militarizedcompetitive and unpredictable.

A medieval poet and some buried trees have just revealed something very strange to us about the 13th century Sun

by

At the beginning of the 13th century, the Sun was passing through a solar cycle much shorter than those that exist today, but extremely intense. Having such specific details is complicated for such a distant time, when scientists did not have instruments to measure this type of activity. However, there is something that today’s scientists do have and that has helped them detect this event: a book of poetry and many trees. Art and science. A team of scientists from Okinawa Institute of Science and Technology has described this event using two types of data. On the one hand, a poem written in 1204 by the Japanese writer Fujiwara no Teika. On the other hand, the observation of the rings of buried tree trunks in northern Japan. The conclusion is clear. While today solar cycles are usually around 11 years, back then there were some 6 or 7 years, but the activity was high enough to lead to the formation of auroras in Japan. A proton explosion. When solar activity is very intense, phenomena such as solar flares or the coronal mass ejections. The first is a sudden release of electromagnetic radiation from the solar surface, while the second consists of the expulsion of matter, normally charged plasma particles, from the Sun’s corona. Associated with these phenomena, proton explosions occur, in which these charged particles move at high speed. rare isotopes. Normally, a good part of these charged particles and cosmic rays fail to pass through the Earth’s magnetic field. However, when they are very intense they can reach our atmosphere in greater quantities and interact with the gases in it. In this reaction, isotopes such as beryllium-10 or carbon-14 can be formed. These are beryllium or carbon atoms with a different number of neutrons in their nuclei than the beryllium and carbon that are most abundant on Earth. Knowing this process is useful, because it can give us clues on two levels. On the one hand, beryllium-10 is deposited in ice sheets, while carbon-14 It oxidizes, transforming into carbon dioxide and becoming part of the carbon cycle. In this cycle, living beings incorporate it into their cells in different ways. For example, plants do this through photosynthesis. And this is where what has been so useful to these scientists begins. Solar dating and meteorology. Carbon-14 is often used to date fossils, since they come from living beings that once incorporated that isotope into their tissues. The moment a living being dies it stops incorporating carbon-14. From that moment on, it begins to disintegrate at a known rate, so it can be estimated approximately when it died. The point is that, beyond that, if carbon-14 levels are unusually high, it can also be determined if there was an extreme solar event. The poem describes a dawn The poem. in his diary Meigetsukithe poet Fujiwara no Teika described the observation of “red lights in the sky over northern Kyoto.” This city is at a latitude too far south for auroras to form, but that is clearly what it describes. The auroras They are the result of a type of interaction between the gases in the atmosphere and the charged particles of the Sun that causes the emission of visible light. They are normally formed at the poles, as they are the points on the Earth where the magnetic field is most vertical, so that it acts as a funnel, so that these particles can pass through it. When they occur far from the poles it is because solar activity has been very intense and the resistance normally opposed by the magnetic field has been exceeded. What the trees tell. The rings of tree trunks are a kind of natural calendar. They are formed from the inside out, so we can count them and calculate how the years have passed. For this reason, the authors of the study that has just been published They wanted to analyze the equivalent buried tree rings at the beginning of the 13th century. In the rings from the period from winter 1200 to spring 1201 they found an increase in carbon-14 levels. This also agrees with the levels of beryllium-10 found in ice deposits from that same period. Everything agrees. Also in China. There are historical records from the time when Chinese astronomers also described red lights in the sky. Therefore, it seems clear that there were auroras at unusual latitudes. A very rare case. The most curious thing about all this is that this phenomenon did not occur at the peak of the solar cycle. It possibly took place around its periodic minimum. If there was less activity, why so much aurora and carbon-14? This is something that, at the moment, scientists have not been able to explain. Perhaps there were also many auroras at the peak, but no poet stopped to write about them. Tree rings would have to be analyzed to see what carbon-14 tells us. What is clear is that the Sun was burning in those medieval times.

A simple router is a machine capable of identifying humans with almost 100% accuracy. Or so these researchers say

by

Using WiFi networks as a technology to track people is a twist in the script that not all of us saw coming. He Karlsruher Institute for Technologyone of the strongest research institutions in Germany, assures close to 100% accuracy when recognizing people without any type of camera and using it. What exactly happened. The KIT (Karlsruhe Institute of Technology) team published a paper with a promising headline: “Ordinary WiFi can identify people with almost perfect accuracy”. And this is achieved thanks to something that routers have been doing for recent years: beamforming feedback information. How the hell does this work?. To understand what it is about beamforming You must first understand how the devices emit signals. routers. In their first generations, routers emitted in all directions, just like a light bulb emits light in that way. With the most modern versions of WiFi, the way the signal is transmitted has improved. Routers began to concentrate the signal towards where the receiving device is, like a flashlight instead of a light bulb. Beanformig. That is called beamformingto form a concentrated beam and received by another device. But to aim well, the router needs to know where to point, and it is the connected devices themselves—your cell phone, your laptop—that send that information to the router continuously. Basically, they are constantly telling the router “hey, I’m here.” That message is the BFI, beamforming feedback information. And what is this for?. Now you know that your router sends information to your gadgets and that your gadgets send information to the router. When the devices send information to the router, they describe how the signal arrives, and interference along the way is recorded. Among them, human beings. Our body partially absorbs WiFi waves, reflects them, deflects them and alters how they reach the mobile phone or router. The researchers used that signal data to train models of artificial intelligencein order to detect patterns that would allow humans to be detected. They fed the system with thousands of examples associated with different people until the model learned to detect those wave changes associated with human presence. The system is not capable of visually recognizing anything in the environment, but it manages to have information about when a human is present in the environment. The caution. According to the researchers, “this technology turns each router into a potential means of surveillance.” “If you regularly pass by a café that operates a WiFi network, you could be identified there without realizing it and be recognized later, for example, by public authorities or companies.” The reality? It would be necessary for cybercriminals to develop a system identical or similar to that of the KIT to achieve a human video surveillance system through WiFi signals. The nuance. Under laboratory conditions, with 197 participants and in controlled environments, the system was close to 100% accuracy. But in the real world, it would be necessary to train a new model with data from hundreds of people in different spaces. The model is not a ready-to-deploy technology or a real threat – nor is it intended to be applied – but the research reveals how simple a priori data sets can be trained as a surveillance tool.

We have been looking to replace the key ingredient in cement for years. We have found the Holy Grail: basalt

by

In the midst of the era of decarbonizationthe first thing that comes to mind when we think about ways to emit less CO₂ into the atmosphere is the transition to renewable energy or electric vehicles. However, we can often overlook something that sends as many CO₂ emissions into the atmosphere each year as all the cars in the world: the cement. This material is essential and, although We have been looking for a replacement for yearsa team from the University of California believes they have found the key to creating greener cement. A cement without limestone that relies on silicates. Portland cement. It is the basic material that ‘links’ our reality. This paste resulting from the mixture of water, sand and stones is very resistant and, as we say, although we have been looking for a substitute for some time, the truth is that we have not found the key. It is still a structural part of buildings, bridges, dams or tunnels and the problem is that the cement industry is estimated to represent around 4.4% of global greenhouse gas emissions. And one of the problems with this cement is limestone. It is a simple rock to refine, but it requires a lot of energy. It is not that limestone pollutes by itself, but because of the process that must be followed to process it and make it a good ingredient in cement. This limestone must be heated to more than 1,500 degrees Celsius to produce the calcium oxide necessary for the mixture and it is estimated that half of all CO₂ emissions linked to cement production are related solely to that process with limestone. Focus shift. With that in mind, Jeff Prancevic (a geologist at the University of California, Santa Barbara) and Cody Finke (of Brimstone Energy) set out to replace the elephant in the room. If Portland cement is the most used and the limestone refining process is what pollutes the most in the process, the rock had to be removed from the equation. The key? Find other rocks rich in calcium, but that are easier to refine. Basalt to the rescue. And in the study published in Nature They detail how basalt is that rock that meets what they are looking for. After carrying out different analyses, they came to the conclusion that, in theory, manufacturing cement from these calcium-rich silicates can require less than 60% of the energy needed by limestone, reducing CO₂ emissions by 80% in the process. In numbers. It is estimated that, in the refining of limestone, 600 kg per metric ton of cement of CO₂ are sent into the atmosphere, but if we use other silicates, the authors calculate that these emissions could be around 50 kg per ton. In the least conservative calculations, the proposed solution would still cut more than 25% CO₂ compared to the standard process with limestone. Another interesting point is that the processing of these other rocks has the potential to give us valuable byproducts with high iron and aluminum content that could benefit other industries. That is, the material would be used more while contaminating less. The pasta question. The problem is… the same as always. When we talk about a new lbrick from recycled plasticsof sugar bricks or of others in the shape of a ‘staple’ that do not need cement to join together, the bottom line is that the construction industry should make a radical change in its processes. It is a huge liner that cannot be swerved overnight, no matter how many benefits these new materials have. And the same thing happens here. Although it is not about creating an alternative to cement, but rather using other rocks to extract the calcium that the mixture needs, the money comes into play in two ways. The first for the basalt deposits. If the cement industry has been organized around enormous limestone deposits to optimize processes, switching to basalt would imply relocating plants or creating new supply chains that would increase both time and costs. If something works… On the other hand, the margins of the cement industry, which has been shown to be extremely conservative throughout history. There is a product that works and changing something in the chain would involve carrying out a reorganization that they may not want to undertake. There is also the fact that yes, basalt has iron and aluminum as a byproduct, but the plants would have to be conditioned to be able to treat it properly, which would mean a huge initial investment. The authors of the study themselves indicate that it is difficult for an industry that for a century has been organized around Portland cement changed its way of acting one bit, but they also point out that, precisely for this reason, they have focused on finding materials such as basalt that are abundant, with reserves to maintain the current pace of construction for thousands of years and that emit less into the atmosphere. It is obtaining calcium from a different rock and its authors call on the industry, and other researchers, to experiment with new technologies that help accelerate the decarbonization of cement. The problem is that, as we say, there are too many drawbacks that the industry itself probably does not want to take on. Image | Cemco In Xataka | Coal is back in fashion in many countries.

What until recently were small incursions of spring heat have turned Europe into hell

London at 35 degrees in the month of May. We are talking about a record that would be exceptional in the middle of summer. France (“a country where much of its territory is low, soft terrain of little relief”) dangerously close to 40 and discovering how all those cities in the valleys They become “pans like Seville or Córdoba”. Central Europe, the Alps, the former Yugoslavia seeing how the thermometers have gone completely crazy. “Literally hundreds of May records have already been beaten“and the worst thing is that no symptoms are seen weakening on the horizon. The relevant question today may be why. What is happening? “It will never cease to surprise me to see a number (…) so extreme for the time and covering such a large record area,” said González Alemán a few hours ago. And no wonder: each of the little pink dots in the image below are historical heat records for May. This week, Europe has become hell and, despite years of warnings, no one really expected it. How is it possible? The explanation is simple. A powerful subtropical anticyclone has spread over Western Europe and is generating what It is often referred to as a “heat dome”. That is, a situation in which the air on the surface is not renewed, does not move and, as a consequence, warms up little by little. The following two maps show perfectly what this “heat dome” is and where it is affecting most intensely. What do they mean? The first image shows the size and extent of the anticyclone. Right now, much of Europe is cloudless. The second shows the intensity of the phenomenon. As Jeff Berardelli explainsany red dot represents a new record for May (and we are taking the record since 1950 as a reference). This has many names… “atmospheric blocks”, quasi-resonant amplification of planetary waves either persistence of “double jet” configurations about Eurasia. But the result is the same: the problem has stopped being the heat and is starting to be that today’s climatic extremes continue for days and days. “This is perhaps the most obvious sign of the new climate that has nothing to do with that of a few decades ago”. And what can we do? That’s a great question, because these heat waves (if, as they seem, they persist) will have a very clear consequence: Europe will have to change its real estate stock from “houses designed to keep the heat out” to “houses designed to keep it out.” We are facing one of the Image | Tropical TidBits In Xataka | The Gulf Stream is dying.

leave the dog on the terrace

by

The Animal Welfare Law (LBA) was approved in March 2023 and came into force ago almost three yearsbut even so there are still details of the rule that remain unclear among dog and cat owners. Specifically there is a doubt that has circulated in recent weeks, coinciding with the arrival of good weather: Can I leave my dog ​​on the terrace or balcony? If I have a yard, does the law allow the dog to spend there every day and night? The LAB is clear about this. One fact: 6.9 million. If you go to a park in your city (it doesn’t matter which one) and sit on a bench to observe, you are more likely to encounter more dogs than children. I’m not saying it. They say it the statistics. In 2025, the INE had around 1.7 million of people under five years of age. The data does not attract attention only because of how it has been reducing over the years (in 2015 there were 1.9 million), it also does so because it confirms that in Spanish homes there are many more pets than babies. According to the estimates According to ANFAAC, the industry dedicated to producing pet food, in Spain there are almost seven million dogs and 5.9 million cats registered. The ‘photography’ offered by the Spanish Network for the Identification of Pet Animals (REIAC) is somewhat different, but just as forceful: in our country there are between 9.2 and 10.1 million dogs, between 968,000 and 1.2 million cats and thousands of ferrets, just over 50,000. How should we treat them? Taking these figures into account, it is better understood that the guidelines on how to treat and care for them have become a priority. Not only for the safety of the animal. Contravene the rules contained in the Animal Welfare Law (LBA), the rule that has regulated the care of pets since 2023, can also lead to significant sanctions. As a reference, the text contemplates three types of infractions, according to their relevance: minor ones can lead to a simple warning or fines of between 500 and 10,000 euros, serious ones extend that range up to 50,000 and the most serious ones carry sanctions of between 51,000 and 200,000 euros. Pets and terraces. With the arrival of good weather there is a question about pet care that has begun to circulate on the Internet: Can a dog live on a terrace or balcony? Can we put a shed there and make it your permanent ‘home’? And in a patio, in case we have one? Can our pet stay there all the time? The truth is that the LBA is clear on this issue. In your article 27 (section ‘e’), in which it lists the “specific prohibitions” on pets, cites as a prohibited practice “habitually keeping dogs and cats on terraces, balconies, rooftops, storage rooms, basements, patios and similar or vehicles.” And in case it is not clear, later, in article 74, it states that installing an animal “permanently” in any of these spaces will be considered a serious infraction, just like stealing. Does it say anything else? Yes. That is not the only indication that the LBA gives about how and where our pets should live. The LBA expressly prohibits and categorically “intentionally abandon them in closed or open spaces” and remember that the owners must “keep them integrated into the family nucleus, whenever possible due to their species.” When this is not possible due to the type of pet or its size, the animal must have “adequate accommodation, with rooms in accordance with its dimensions and that protect it from inclement weather.” Again, and in case there were any doubts, the LBA insist in which pets that live outdoors must have a prepared place to hide. The other warning. With the summer holidays (almost) knocking at the door there is another guideline of the LBA that should be kept in mind: if you have dogs or cats, the law does not allow you to go on vacation for days and days and ignore the animals. It is not enough to leave the water bowls full and the feeders overflowing. In article 25, the same one in which it talks about terraces, the law prohibits “leaving any pet animal unsupervised for more than three consecutive days.” What’s more, if we talk about dogs, that period cannot exceed 24 hours. Much more than a law. That the LBA goes into such detail and regulates such basic issues may seem exaggerated, but the reality is that today they can still be found. without much effort news about dogs that their owners confine on terraces, sometimes no food or wateror even in window sills. Veterinarians also warn often of the serious risks involved in leaving animals exposed to the hot sun. Above all if we talk about closed and small spaces, like cars.
