The AI has folded the price of an ultrarrao metal. The problem is that we need it to store renewable energy

by

Two technological revolutions are redefining, at the same time, the entire energy sector: the transition to renewable sources and the unstoppable boom of artificial intelligence. The first needs cheap and efficient batteries. The second has an insatiable data appetite and needs hardware to store them. The problem is that both are colliding in the market of An ultrarrao metal: Ruthenium. And the AI is winning the battle. Ruthenium is in historical maximums. In the last year, this discreet silver gray mineral has become The unexpected star of raw material markets. Its price has doubled, reaching $ 25,720 per kilogram, according to data from the Johnson Matthey metal refining that Bloomberg collects. The figure not only eclipses gold or silver increases, but also touches its historical maximum of $ 27,970, reached 18 years ago. What has unleashed this fever. The answer is in data centers that feed artificial intelligence. Ruthenium, a Platinum Group metal, is exceptionally hard and versatile. One of its applications in electronics are high -capacity hard drives, which use a river layer of less than a thick nanometer to greatly increase data density. As the generative AI and the Cloud Computing They demand to store astronomical amounts of information, the demand is triggered. But the background problem is scarcity. Ruthenium is one of the most rare elements of the earth’s crust. It is obtained almost exclusively as a byproduct of platinum mining, and its annual supply is tiny: just 30 tons last year. Unless the investment in mining increases, analysts expect the market Enter in deficit next year. That is, the demand exceeds the supply. Not only does it need Ruthenio. In addition to hard drives, metal is a vital component in Several of the most promising chemists For massive energy storage batteries. Ruthenium oxide offers unique capacitance and loading and discharge speed, so It was intended to be used in Super Current before the AI duplicate its price. It is also a necessary metal In lithium-oxygen batteriesconsidered one of the next great revolutions in batteries for its very high energy density. But these cells depend on efficient catalysts. Ruthenium nanocatalysts achieve extraordinary capabilities and life cycles, but with the current price they are unfeasible. How it affects the energy sector. No sector is able to face investments as large as that of artificial intelligence. The AI is staying with the Ruthenium to save data while the entire planet faces another urgent challenge: store energy to abandon fossil fuels. Intermittent renewables, such as solar and wind, need large -scale batteries to keep the energy they generate when the sun shines or the wind blows, being able to use it later when night falls or the wind stops blowing. According to the International Energy Agencyin 2023 42 GW of capacity in batteries were installed, more than double than the previous year. It is an impressive, but insufficient figure to meet the objectives of the Paris Agreement. The world needs to multiply that rhythm by six and reach about 1,500 GW of storage capacity from here to 2030 (of which 1,200 GW would be batteries). Is there any alternative to Ruthenium? There are other technologies that allow storing large amounts of data, but they are very expensive, so the industry continues to bet on ruthenium. In fact, a report by International Data Corp. provides that sales of hard drives with Ruthenium will increase 16% this year, dragging metal stocks. Researchers from all over the world have spent years developing new advanced batteries assuming a price for ruthenium that, although high, was manageable. Now, the explosion of the demand for AI has created a cost curve that no one anticipated, and that forces to start from scratch.

We are champions in productivity with medium and large companies. The problem is that with SMEs we lose by win

The OECD data has been putting the red lantern to Spanish productivity decades. However, that perception does not Low productivity in Spain It does not fully adjust to the reality that reflect the Recent OECD reports. Such and as they highlight in The confidentialalthough the global data show a very discreet increase, companies of between 10 and 250 workers exceed productivity to the average of their peers in the OECD. However, the big problem is that 95.1% of Spanish business fabric is made up of SMEs with between 0 and 10 employees. What the OECD says about Spain. The OECD, in Your productivity report Of 2024, it evidences that the average annual growth of the hour per hour worked in Spain has been 0.5% per year, while the OECD as a whole has registered an average of 1.2%. That places the country clearly below the average of the Club of developed economies. Despite this scenario, a BBVA Foundation Analysis On the evolution of the total productivity of the factors (PTF), which combines the productivity of labor and capital to leave a photo closer to the reality of companies, says a growth of 0.9% interannual of this parameter. Which reinforces the conclusions of the OECD on the growth of productivity in Spain, which is like the Second country with greater growth of productivity in the last two decades. However, beyond the global data of Spain, the graphics of the OECD productivity study value the largest companies already medium -sized as a productivity engine in Spain. Thus, the OECD evidence that the mismatch in productivity is not so much between Spain and Europe as a whole, but among the different company sizes within the country itself. Total productivity of the factors (PTF) by country. Source: Productivity Council of Spain Microenterprises: many and unproductive. As recognized From the report From the Productivity Council in Spain, the most relevant feature of the Spanish productive fabric is that 95.1% of Spanish companies have less than ten employees, confirming that microenterprise is the standard in Spain, not the exception. According to the OECD dataSpanish microenterprises generated in 2023 an added value of $ 56,990 per worker, compared to $ 108,356 per employee generated by large companies. That means that large companies are 90% more productive than SMEs. The productivity of microenterprises is 15.3% below the OECD average and represents one of the main ballasts for the national average. He OECD diagnosis On microenterprises it is clear: having many very small companies limits the Productivity improvements and investment capacity. Medium companies approve with note. The highlight of the international comparative analysis is that, according to the OECD, “Spanish medium -sized companies have a productivity higher than the EU average, standing above the other advanced countries in their category.” In percentage terms, Spanish companies of 10 to 49 employees are 8.7% more productive than the OECD average; those of 50 to 250 employees 9.1% and those of more than 250 employees 5.2%. In other words, only 4.9% of companies in Spain would be above the OECD average, occupying avant -garde positions in terms of competitiveness in markets International The challenge: increase size and investment. The recipe that the OECD gives to Improve productivity Of these microenterprises it is clear, but it is not simple to apply: it is necessary to seek improvements in productivity through Investment and innovationimproving the value added by employee so that the business fabric gains size. According to 2023 dataSpain is at the tail in investment in machinery, ICT assets and i+d. Precisely, a Report of the Bank of Spain He pointed to productive investment as the key to business growth. The report emphasizes that private business investment had not managed to recover prepondondemic levels, while public investment in this area had recovered and grew at a good pace.

Gold is one of the metals with better electrical conductivity. For this reason, it is used in many electronic components, mainly in computers, but also in smartphones or sound systems. The problem is that extracting it from these pieces is very complicated and the cost it means does not compensate. Or we believed. Swiss researchers They have created a method to extract precious metal from a serum protein. Find gold in the trash. The components where gold is used most They are the PCB or printed circuit plates that we find in all types of devices, from computers to smartphones. It can also be found in processors, connectors and HDD hard drives. The problem, as we said, is that the existing methods to extract this metal are very complex and expensive. In addition, it is often necessary to use very toxic chemical components, although that does not stop that many Try it in your own houses. For all this, it is often not worth the effort to the small amounts that are extracted. The extraction process. Whey protein. Researchers at the Federal Polytechnic School of Zurich have managed to extract gold with a new more efficient, sustainable and cheap method. As? With serum protein ‘whey’ (yes, the Gym shakes). To do this, they submitted proteins to acidic conditions and high temperatures. These form nanofibers that are added to a gel and, after drying, forms a kind of sponge. It is not the first time we hear that Whey protein is used for similar purposes. A few months ago China managed to recycle the electric car batteries thanks to the glycine present in these shakes. Who was going to tell us that in addition to getting strong, it would serve to extract gold or recycle batteries. The method. The researchers used 20 computer base plates, from which they extracted all metal parts and dissolved them in an acid bath that ionized the metals. The next step was to submerge the sponge in the solution. Although there are other metals that adhere to the fibers that form it, the researchers discovered that gold ions adhere much better. Once “captured”, the sponge is heated and the ions are released and can melt to create a gold peep. Cheaper. The 20 motherboards resulted in a 450 milligrams gold cupcake with 91% purity (the remaining 9% was copper), or what is the same: 22 korates. At the current price of gold, La Pepita would have a value of about 35 euros. It is not much, but the researchers affirm that the cost of the materials and energy necessary for extraction is 50 times less than that of gold obtained. The next step is to climb this technology to be able to apply it to the market. Images | Eth zurich In Xataka | Our dependence on lithium batteries is worrying.

The Ave to Andalusia seemed a perfect alternative to the car this summer. Has encountered a problem called Toledo

by

We are on July 14, summer trips to the south of Spain multiply. High speed had to offer a quick exit to the sea from Madrid, connected to Malaga by trains of up to three different companies. But, in what we have been from the month, the problems have multiplied until thinking that the usual is already suffering some type of delay. Catastrophic misfortunes. In case their own problems were their own, this weekend Spanish high speed has suffered more and more delays. Even for reasons that have nothing to do with the trains themselves. Catalonia and suspensions or delays caused by heavy rains They are a good sample of this. But the worst part, again, takes Andalusia. The Autonomous Community has had a first look in July to forget. After 15 days in which the delays have been a constant, yesterday, Sunday, July 13, A fire next to the tracks Among the Cordoba municipalities of La Marota and Santaella cut the circulation again. In total, only Renfe already registered 10 modifications at his schedules. In the afternoon, at 5:49 p.m. they pointed out that The circulation would gradually restore. Own problems. The fire next to the tracks has only been the drop that has filled the glass of a weekend that had already registered problems on Saturday. An incidence in the Adif facilities again caused delays in trains that were directed on the way Andalusia or Madrid. Again, a good handful of trains recorded delays of more than an hour on the ferrous roads of the Andalusian region. The incidence in the facilities was found in the vicinity of La Sagra (Toledo), where at the beginning of July the biggest Ferroviaro problem was recorded in these first two weeks of the month. 13 hours arrested. Julio began his journey in summer in a very worrying way in southern Spain. Thousands of passengers (it is estimated that more than 16,000 people) were affected by a problem in the lines that extended for more than a day. The problem caused a collapse in the high -speed line that resulted in the suspension of services and The stop (without assistance) of more than 13 hours of a train that ended up meeting the night. Over there, An old woman had to be treated For respiratory failure. Many reproaches … Since that stop happened in high Andalusian speed, the government, Adif and Ouigo have been sent Cross messages for the problems caused. The origin of the fault He was in a disconnection of an ouigo train with the signal recognition system, mandatory to continue operating. His stop forced to stop the trains that circulated below. The cluster of vehicles caused an over -line over the line that resulted in a fault of a Renfe train. The latter did not unwill for a problem in their own systems that force disconnection to avoid breakdowns in case of over -overdraft. Ouigo has not rejected his involvement in the incident but he did defend himself from The words of María Jesús MonteroMinister of Finance and Vice President of the Government, to whom open microphones captured her criticizing the company. The French blamed Adif that Insphorastructure had to endure unforeseen Like these. … And few solutions. After the chaos of the first days of summer, Adif announced that he would carry out an emergency action on the line and that he got to work to identify the weak points of the Andalusian connection. A movement that Ouigo pointed out how insufficient. Those actions They were going to be carried out in La Sagra. Yes, exactly at the same point where the over -the end of the month of July was produced that ended with all the circulation stopped for more than 13 hours. There, ADIF plans to perform an emergency action by changing the location of various elements of the catenary. Two weeks later, trains stand up again in the same place.

I thought I had a problem with the ABS of my car, but it caught me in surprise to see that it was something completely unexpected: rats

by

The ABS light flashing on the dashboard is never a good sign. Almost none Witter of the dashboard It is, but when the engine witness also adds, you start imagining four -digit figures in the workshop budget. The funny thing is that when I took my car to fix it, I discovered something that I never imagined what would happen: The rats ended up biting several cables Internal of my car. The initial diagnosis. When I arrived at the workshop with the warning lights on, the mechanic, after an inspection of the car, assured me that I could change everything The ABS system. A new one for my Seat Ibiza TDI 1.9 of 2005 can be a rather important expense, one of those expenses that you think if you better pass it, since it is dangerously approaches the price through which I could sell the car today. The price of the second -hand and scrapping ABS system, the thing changes. One can lead normally if the ABS does not work, but it is a risk for security, since it compromises the emergency braking and we do not have that help that the car gives us at critical moments, allowing our brakes to end up blocking. The real problem. After almost a week in the workshop and a more detailed inspection, the mechanic discovered the authentic cause of the failure: the ABS system cables and some that communicate with the engine They had been bitten. It was not a normal wear or component failure, but the rats had been roying the car cables. For a rat, gnawing cables and objects that are in its path is their day to day, since their teeth do not stop growing throughout their lives and need some means to polish their teeth. What a pity they had to run into my car. Unexpected, but in a way, relieved. What seemed like a serious problem with the brake system and the emergency light of the engine was solved with a cable repair. The joke came out for about 120 euros. A considerable relief compared to the complete change of the ABS that initially the mechanic had raised. From the workshop they repaired the damaged cables and the dashboard warning indicators were turned off. The background problem. Now the real challenge is not in the car, but in the garage. It is a private garage under a floors building where several vehicles park. Days before I had already seen a rat that was shot from under my car to a hole that is right next to my parking space. From the workshop they recommended preventive measures such as spraying in the vain motor or placing camphor balls, especially useful when the car remains a long time stopped. Of course, this should be done with the car standing and cold. I bought the spray as a temporary measure until they finished solving the hole in the garage. And now what. The priority is to cover the garage hole where the rats access, since the alternative remedies will be of little if the problem persists right next where I appear. Fortunately, it seems that garage insurance will cover the workshop spending, which good news for that part. In addition, we are already mobilizing the community to solve the problem of rats. I could have changed their garage directly, although things are not currently to make this decision lightly. We will see what everything is left.

For centuries the Christians pilgrimage to a remote cave to venerate Salome. Problem: They were wrong with Salome

by

There was a time, many centuries ago, in which Christians went to an old cave located in the Judea Lowlandsnear the village of Eliav, in search of inspiration. Over the years even a Sacred place For Islam. There (the remains of Salome were supposed to be, a biblical figure with echoes in the origins of Christianity. Some versions identified it as the midwife that attended the birth of Jesus. Others as one of his disciples and witness of the crucifixion. It is even said that she was Maria’s little sister. Now a group of Israeli archaeologists has reached a fascinating conclusion that relies on vestiges located years ago In the cave: I probably Salome that rested in his day in the crypt was neither the midwife nor disciple of Jesus, but an opulent and powerful aristocrat related to Herod. In a place of Judea … The Salomé cave is a wide sepulcher located in Sefeláthe lowlands of Judea, with an exceptional archaeological value. In fact there are those who consider it one of the funeral caves “More impressive” discovered in Israel and “More elaborate” of his time, the known as period of the Second templewhich extended between the centuries VI AC and I DC Specifically, experts believe that the crypt built between the I AC and I DC The cave itself is no novelty. The archaeologists excavated it decades ago, in the mid -80s, after they were located. Throughout the last years, however, they have expanded our knowledge about the grave. By 2022 A group of experts from Israel Antiquies Authority (IAA) made an excavation in part of the enclosure that revealed new data on its architecture and history. He also confirmed that for several centuries that remote Cave of Sefelá was used as a veneration space. And how is it? Wide. Elaborate. And fascinating. The archaeological set includes a lobby, a large patio surrounded by silry stone walls and a funeral cave with several cameras in which they were preserved Kokhimfuneral niches excavated in the rock, in addition to ossuaries. Although archaeologists studied the thorough crypt in the 80s, a few years ago they wanted to go further, analyzing in depth The 350 m2 courtyard and cleaning the inside of the cave. “The patio turned out to be one of the most elaborate of its kind compared to other cemeteries of the same period,” he says An article Posted by the IAA. Among other things, experts met stones with Jewish motifs and “delicate plant designs,” such as rosettes, grenades and acanthus vases. Nothing to do with most access courtyards to funeral caves found by archaeologists, who are usually excavated, not raised with masonry. Cave … and pilgrimage place. If the grave is so relevant, it is not only because of its size, architectural characteristics or decoration. There is another equal or even more relevant factor. For a while the cave was a pilgrimage place. During their excavations of 2022 and 2023 in the front courtyard, archaeologists discovered a row of positions in which clay lamps were sold and rented. “We find hundreds, complete and broken, dating from the eighth centuries and IX DC”, They explain Nir Shimshon-Paran and Zvi-Fire, directors of the excavation. “The lamps may have served to illuminate the cave or as part of religious ceremonies, similar to the candles that are distributed today in the tombs and churches,” They add. In the cave, Greek, Syriac and Arab inscriptions, recorded crosses and indications that reveal that the funeral space remained in use during the Byzantine and Islamic periods were also located. “The excavations show that, in the Byzantine period, the site had become a place of Christian pilgrimage,” experts say, which tells us about a wide period of worship that covers from the 5th century to the IX DC DC The cave of Salome. The question was obvious … Who belonged to the funeral cave? Who rested in his day in the crypt? And why the archaeologists found crosses and dozens of inscriptions recorded directly on the rocks of the walls? The answer is both simple and complex: the Sefelá cave was the resting place of ‘Salomé’. Among the inscriptions in different languages, archaeologists identified several in Greek that mention that same name, ‘Salomé’, supposedly a religious figure relevant to Christians. In An article Published this year on the sepulcher, IAA experts remember that, in the 1090s, the scholars that analyzed the inscriptions have already concluded that the first monks who arrived in the cave in the Byzantine period discovered an ossary with the inscription ‘Salomé’, a relatively frequent name in the Judea of the beginning of the beginning of Christianity. “During the second temple period it was not common Explain Paran to The Times of Israel. “It is possible that the cave contained an ossuary with the name of Salome, although we did not find it. It could have been looted.” So … who was the famous Salome? The midwife of Jesus? A tradition attributes that name to a figure that appears in it Protoevangelio de Santiagoapocryphal text in which a Salomé is cited as a midwife that doubted the virginity of Mary. The story tells that his disbelief earned him a punishment that ended up turning it into a symbol. “According to the Christian tradition, Salome was the midwife of Bethlehem who was called to attend the birth of Jesus. He could not believe that they asked him to participate in the birth of a virgin and his hand dried. He only healed when he held the baby’s crib,” Remember From the IAA. Other versions They place Salome as a disciple of Jesus, Mary’s sister or has even confused her with the mother of Santiago and Juan. “The cult of Salomé, sanctified by Christianity, belongs to a broader phenomenon: the Christian pilgrims of the 5th century found and sanctified Jewish places. The name Salome could have appeared in ancient times in one of the alter’s already disappeared from the tomb and thus the tradition … Read more

Grok 4 destroys the tests and aims to be the most advanced AI model. The problem is that Elon Musk continues to sabotage his answers

by

Xai has launched Grok 4its new artificial intelligence model that is sweeping the most demanding performance tests in the sector. The model exceeds OpenAi, Google and Anthropic proposals in multiple benchmarks. And is that in the absence of knowing OpenAI’s strategy with GPT-5At the moment it has all the ballots of being the most pointer the model. However, Grok continues to drag the usual problems: controversial responses, offensive content and an Elon Musk using the model to subtract credibility. The numbers speak alone. In the test Humanity’s last examconsidered one of the most difficult to measure abilities of AI, XAI states that Grok 4 has achieved 25.4% Without additional tools, surpassing O3 of Openai (21%) and Gemini 2.5 Pro from Google (21.6%). But it is with Grok 4 Heavy, its multiagente version, where the results shoot: according to the company, reaches 44.4% With ‘tools’, almost doubleing competition. Image: XAI In addition, at the benchmark ARC-AGI-2which measures the ability to solve complex visual patterns, Grok 4 has obtained 16.2%practically double the next commercial model. According to Musk“Grok 4 exceeds the doctoral level in all subjects, without exception”, an affirmation that, although it sounds to marketing, is supported by the results obtained. The revolutionary approach. Grok 4 Heavy works with A “multiple agents” system that work in parallel about the same problem, then comparing their results as if it were a study group. This architecture allows you to climb intelligence according to the available computational power, a concept that could redefine how we understand the AI ​​performance. Image: XAI The usual problems. The launch of Grok 4 occurs just after the previous version of the chatbot published anti -Semitic comments In X, even identifying as “Mechahitler” in some answers. XAI had to temporarily withdraw the service and eliminate offensive publications, while countries like Poland They announced complaints before the European Commission and Türkiye blocked access to chatbot. The cause was a modification in the system instructions that allowed the model “not to avoid politically incorrect statements.” Although Xai withdrew that guideline, the damage was already done. A constant sabotage. Despite these technical advances, Musk continues to condition Grok’s responses in ways that compromise their usefulness. The model performs automatic searches for the opinions of the tycoon in X to respond to controversial issues, turning the alleged search for “truth” into an echo of its creator’s ideas. This practice, confirmed By experts in AI like Carlos Santana, he once again demonstrates how Musk’s controversial decisions are directly influencing the development of the model. In addition, several researchers already They have managed to avoid Easily model safety barriers, making it generate content on chemical weapons, malicious software, drugs and other sensitive issues through relatively simple jailbreak techniques. Ethan Mollick, professor at Warton and an expert at AI, Point out The lack of transparency of the company: ‘There is no detailed technical documentation, risk analysis or explanations on how to avoid future incidents’. This opacity makes it difficult for companies to trust Grok for critical applications. Grok 4 prices. XAI Grok 4 Basic offers at a price of about 30 dollars a month. However, the company has also launched Supergrok Heavy, a subscription of $ 300 per month in which its most advanced model is offered and that directly becomes the most expensive market service on the market. What is coming. XAI plans to launch a programming model in August, multimodal agents in September and video generation in October. Also will integrate Grok 4 in Tesla vehicles Next week, expanding the scope of AI throughout the Musk ecosystem. The question is whether the company will separate the technical excellence of the media controversies that surround it, or if it will remain hostage of its founder’s impulsive decisions.

Wimbledon has replaced all his line judges with a success. The only problem is that tennis players do not believe it

by

Wimbledon has replaced This year for the first time in its history to its line judges for a technology that is an evolution of the traditional eye of the hawk. Despite the accuracy it brings, several tennis players They have expressed their discontentespecially following the controversy with the party of Kartal and Pavlyuchenkova. What’s happening. Several tennis players have publicly expressed their doubts about the electronic system. Jack Draper and Emma Raducanu, the British numbers, have questioned the accuracy of decisions, while the Switzerland Belinda Bencic It was more direct: “I do not trust the system. Nor is it that I want to speak it too much, but it is really stressful.” The reluctance about this new system are increasingly common in tennis. Although the hawk’s eye has accompanied the games for many years already, The replacement of the judges It marks a general discontent in several professionals of this sport and fans. AND The case of Pavlyuchenkova He has put the situation more inri. Failure in three key situations. The incident that has been playing the most in networks was during the match between the British Sonay Kartal and the Russian Anastasia Pavlyuchenkova on the central track. With the marker matched 4-4, a Kartal ball clearly came out, but the Hawk-Eye system remained silent. Without the usual sound signal of “out”, the referee ordered to repeat the point, causing The frustration of Pavlyuchenkova: “You have stolen the game.” The ruling lasted 6 minutes and 49 seconds, during which the system lost three decisions. The AI ​​is working. The organization has revealed that the problem of Pavlyuchenkova was actually a human error: an operator accidentally deactivated part of the cameras with a click on their computer. Sally Bolton, executive director of All England Club, He has defended that “the ball monitoring system has worked optimally and effectively” throughout the tournament. After the incident, they have modified the software so that the cameras cannot be deactivated manually when there is an ongoing game. How the system works. The Live Electronic Line Calling (Live Elc) that Wimbledon uses is An evolution of the traditional hawk eye that we have been seeing since 2007. The key difference is that it now works in real time: use a network of cameras with artificial vision that tracks the ball and automatically emits an “out” when it goes out. Before, the hawk’s eye was only used to review decisions when players requested it; Now he is the main referee of all lines. It has been working for years. Studies show that electronic systems in sport are significantly more precise than human judges. An investigation He revealed that line referees make mistakes in 27% of cases where the check -up review is required, which is equivalent to an error every 17.4 games. The system has demonstrated its reliability in multiple sports for more than a decade, and both the Australian Open and the US Open have integrated it in its entirety in recent years. AI and arbitration, whenever complaints. Resistance to technology in arbitration is not exclusive to tennis. THE VAR IN FOOTBALL It generates constant controversies. In addition, Hawk-Eye is also implemented in volleyball, Cricket, and even in football for ghost goals, situations in which there has also been controversy with technology. And it is that sport is usually very reticating to technological changes. We don’t trust technology. Machines fail less than humans, but Perception is usually different. And it is that many problems attributed to AI are actually errors in the implementation or in human decisions that accompany the system, as has happened this time in Wimbledon. Technology is not infallible, but it is statistically more reliable than any available human alternative. And why don’t we trust? According to Gina Neff, a teacher in Cambridge, “right now, in many areas in which AI affects our lives, we believe that humans understand the context much better than machines,” he says. “The machine makes decisions based on the set of rules for which it has been programmed. But people are really good when it comes to multiple external values ​​and considerations as well – what is the right decision may not seem like the fair decision,” he continues. “It is the intersection between people and systems that we have to do well.” “We have to use the best of both to make the best decisions.” Cover image | Shep Mcallister In Xataka | 150 years ago the English played the first football matches in Spain.

Aemet at last at the end of the extreme heat tunnel in Spain. The only problem is what comes in place

by

During the last weeks, the successive hot episodes (including the heat wave at the end of June and early July) have alternated with the arrival of vaguades that offered a certain thermal relief. A relief loaded with storms and hail, but relief after all. However, the dynamics of recent weeks seem to have broken. Postbile Dana. Meteorological models foresee the possible formation of a DANA, an isolated depression at high levels. This phenomenon, Experts of Meteoredthis phenomenon would bring more hailstorms in addition to winds of consideration. Two masses of air. The arrival of the Dana would also occur in a context also different from what we had seen in a June where the heat was extended by almost the entire peninsula. The first days of this are mana are characterized however by A two -speed Spain: With a mass of cold air installed in the peninsular north and a warm air dominating the center and the south. The long -awaited thermal relief is therefore produced at two veliocities, more quickly in the north (where temperatures have already moderated) and more slowly in the south, where the thermometers will move away from the 40º mark but with a slower stabilization. Uncertain weekend. That would be the context in which Dana could make an appearance. There is still uncertainty about how the “Descolgue” of this area of ​​low pressures will be and its entry into the Peninsula, but the simulations indicate that the arrival of this phenomenon will occur between Friday 11 and Sunday 13. More storms, more hail. This leaves us a panorama of uncertainty for the end of this week: if this arrival of the DANA occurs the instability could be high and that means that we could see a new rough storms with rainfall and strong winds. According to the modelsSaturday will be the day when it is noticed in our environment. According to these same models, the most affected areas will be the north third, the northeast peninsular and part of the Mediterranean coast. A summer of uncertainties. The question now is to know what will happen after this week of relief. While the warm episodes of the last month and a half had been interspersed for days of storms and temperature reduction, these stops in the thermal escalation had been rather brief. This week however the arrival of several troughs, including an associated with the possible Dana could involve a somewhat more marked reduction in temperatures. For now it is soon to know what will happen. The Monthly prediction From the State Meteorology Agency (AEMET) points out that we still have hotter weeks than usual for these dates, between 3rd and 5th warmer than the average. The quarterly forecasts Aemet also indicates that we have several warm months ahead: 70% probability that it is.

The strokes have become a huge silent health problem in Spain. And there are ways to limit risks

by

Every year 90,000 cases of strokes are produced in Spain that leave 23,000 deaths on average, According to the data of the Spanish Society of Neurology. This number could be significantly reduced, after all, many of the Risk factors which are associated with this type of event correspond to behaviors and habits that we can modify. Before reviewing what the risk factors are controllable or not, associated with the stroke, maybe it is appropriate to consider us What exactly is an stroke. The stroke or stroke (stroke) occurs when the blood flow that reaches a part of the brain is interrupted or drastically reduced. There are two types of accidents: ischemic and hemorrhagic. The former are the most common, are produced by the blockade of one of some circulatory route, for example by a clot or its narrowing as a result of fatty deposits. Hemorrhagic strokes for their part are produced by the breakage of a blood vessel. There is no exact list of risk factors that are related to these episodes since there are numerous overwhelms and interconnections Among these factors. Nor can we make an accurate distinction between the factors that we can control and those that do not. A clear example is that of diabetes. This disease is a risk factor in the appearance of ICUTS. Suffering or not this disease is not under our control, but we can avoid factors that in turn are linked to it. Despite the difficulties when delimiting these concepts, experts estimate that controllable risk factors are associated with 60% and 90% of the risk of suffering a stroke. That is, avoiding these factors we can reduce very significantly the risk that this type of event will be triggered in our brain. And what are the risk factors on which we have the greatest control? According to the National Heart, Lung and Blood Institute From the United States, controllable risk factors include blood pressure, obesity, physical inactivity, poor diet and tobacco. According to the American medical institution Johns Hopkins Medicinea blood pressure of 140/90 or higher is a factor that can condition our probability of suffering such an accident. Obesity, food and physical inactivity They are clearly interconnected risk factors. Smoking is one of the Risk factors More widely mentioned, but alcohol and some recreational drugs such as intravenous or cocaine are also related to an increase in the risk of suffering from an stroke. Some legal substances such as the contraceptive pill have also been related to an increased risk of stroke. With anxiety, depression and stress, something similar occurs than with other diseases: we have a certain degree of control, but this can be very limited depending on the circumstances of each person. Something similar happens with the environment in which we live: although residing or working in contaminated areas can aggravate our risk of suffering from an stroke, changing work or residence is often not in our hand. What we cannot change Some of the risk factors that we associate with the stroke totally escape from our control. Maybe age is the most important: Age. As we become greater the possibilities of suffering a stroke are increasing. Sex is another factor linked to the appearance of this disease and in a unique way: it is fine at an early age men suffer from these accidents more frequently, the greatest life expectancy of women means that throughout life these suffer more such problems. Different ethnic backgrounds can lead to different levels of risk: in the United States African -American, native and Hispanic people have a higher risk of suffering a stroke. Finally, Genetics And family history can also be considered risk factors, especially in cases where a family member has experienced one of these events at earlier ages. In addition to the risk factors, it is worth remembering what are the main symptoms that accompany these events in order to better identify an stroke and improve the chances that whoever suffers it receives medical assistance on time. There are a few key factors that can help us Identify an stroke quicklybut there is also a challenge of symptoms that can also be associated with strokes. Among the Key symptoms There are the loss of strength or sensitivity in the face, arm or leg, which usually swams to a single side of the body; Confusion in speech, for example in the use of unconnected words; sudden loss of vision; dizziness, loss of balance or the appearance of a severe headache without a clear origin.
