In 2021, Catalonia managed to get rid of the AP-7 tolls. Five years later he has an idea: recover them

On October 6, 1998, 16 city councils, four regional councils, the two municipal associations of Catalonia, three chambers of commerce and other entities from different fields formed a common front to reduce and rationalize tolls, with the ultimate objective of bringing the situation in Catalonia – with many payment methods – into line with that of the rest of Spain (…). In a 10-point manifesto called the Gelida Declaration, the signatories constituted an anti-toll front and opposed the latest agreement then approved by the Spanish Ministry of Development, the Generalitat and the concessionaire Acesa, which saw exploitation concessions extended until 2021. In exchange, the concessionaire lowered the amount of the tolls. This is how he headed The Newspaper your article AP-7: history of a business and a claim in 2019. It reviewed the, at that time, 20 years that various city councils and associations had been demanding that the AP-7 lift its barriers. And drivers had been paying for the use of that highway since its opening in sections between the 70s and the first half of the 80s. The situation became even more tense when, as we read above, the concession was extended to 2021. It was then that the images of drivers who They refused to pay when passing through the AP-7. In 2021 things changed. The concession ended, it was not extended and the barriers were raised. From that moment on, cars no longer stopped at toll booths. But that had its consequences. Consequences that, once again, bring the shadow of the toll. Too much traffic And the fact that the highway was free brought with it an immediate increase in the volume of cars that traveled on it. Only in its first year free of tolls, the volume of cars grew by 40% and that of trucks by 80%, they pointed out in The Country. With Barcelona as one of the key steps in the entry and exit of vehicles and the passage through the French border, the road has been taken over by trucks. Traffic is now slower and more dangerous. In fact, that first year the highway concentrated 20% of accidents registered throughout the autonomous community. Since then, organizations have been looking for solutions. The last to leave his proposal was Manel Nadal, Secretary of Mobility and Infrastructure, in Chain Being where he has assured that if public entities agree, they could have tolls on this road again “in two or three years.” In his statement, Nadal even points out that not only the AP-7 would once again put barriers in the way of drivers. The proposal is to apply it to the rest of the high-capacity roads to diversify traffic and prevent a funnel effect from occurring as has happened with the free use of this road, which has now become the favorite route for transport companies that have a free passage to France. In the middle they rescue the words of Salvador Illa, president of Catalonia, who has already pointed out that “perhaps we were wrong when we all asked for them to disappear.” They rule out, according to Nadal, a possible Swiss-style Eurovignette (the driver pays a flat rate per year to drive on toll roads) because they assure that Europe would not accept it after 2032. And Europe has been putting pressure on Spain for a long time to turn your free roads into toll roads. For now, Governments have turned a deaf ear because the cost of implementing the measure is very high but we have been there for more than a decade with this possibility floating over our roads. Meanwhile, the authorities in charge of traffic control seem to be doing the best they can. In some sections speed limits have been drastically reduced and in the Servei Català de Trànsit (SCT) They have been working for some time to implement dynamic speed limits that reduce or increase speed depending on the volume of cars and trucks passing by at any given time.

Electric car sales in Europe, on a revealing map with a devastating peninsula. Spoiler: it is not the Ibérica

If tomorrow your car breaks down and you have to buy a new one, the million dollar question is: Would it be a combustion car, a hybrid or an electric car? Obviously, there is also another respectable alternative that makes a lot of sense in the face of a future full of uncertainty and skyrocketing prices: bet on second hand (however, the question remains the same). Saying goodbye to old combustion and welcoming electricity (in any form) is a complex issue where factors such as tax policies, infrastructure and income come into play. The transition to electric has been here for a long time, but it is not advancing in the same way throughout the continent. The map you see below these lines represents the percentage of new electric car registrations in Europe in 2025which includes pure electric and plug-in. Another important consideration: it only collects new cars, not the existing fleet, that is another much more modest story where electric cars currently represent only around 5%. Its creation is the work of The World in Maps, an informative project specialized in cartographies and infographics. To prepare it, use the report Global EV Outlook 2026 from the International Energy Agency (IEA), published in 2026, that is, the world reference report on electric mobility. Electric cars (EV and PHEV) registered in 2025. AIE On the old continent, sales of electric cars (EV + PHEV) increased by 30% last year, above the global trend, which grew by 20% to exceed 20 million units. That is to say, if in the world one in four cars is electric, in Europe it is almost one in three. In fact, Europe has surpassed China as the fastest growing electric car market, with notable increases in Germany, Spain and Italy. But the colorful map suggests a very heterogeneous panorama on the continent and part of the blame lies with state policies: public support for electric vehicles, in the form of direct subsidies, tax incentives and tariff exemptions, has been progressively decreasing in the last decade as sales have increased, although Denmark, Norway and Turkey continue to have the most favorable scenarios due to their strong tax exemptions. A Europe at two speeds Electric Europe is made up of the Nordic countries and the Netherlands, where the highest quotas are concentrated: Norway (97%), Denmark (71%), Sweden (61%) and Iceland (62%). The recipe for success is a high per capita income, strong taxation on fossil fuels, historic exemptions for electricity and a highly developed charging network. Norway takes the cake, where fully electric cars reached a record share of 96% of all car sales in 2025, although from 2026 the tax advantages have been cut. The Europe of fuel comes from the east, with Russia (2%), Bosnia (5%), Romania and Bulgaria (6%) as markets where the electric car has barely penetrated, conditioned by lower purchasing power, scarce charging infrastructure and absence of relevant tax incentives. In fact, Croatia, Greece and much of the Balkans move in similar figures, between 5% and 15%. This ancient Europe lives under the restraint of increasingly strict EU regulations. These data matter because road transport is one of the major sources of emissions of carbon dioxide in Europe and the speed of electrification attacks it directly, stepping on the accelerator towards achieving the EU’s climate objectives. But it also has industrial implications: the automotive sector, a true historical bastion on the continent, is adapting and planning based on demand. The jump to electric also has its economic and geopolitical reading where one country leads the way: China.

we have also changed the axis of rotation

A couple of decades ago, scientists at NASA’s Jet Propulsion Lab they estimated that the filling of the Three Gorges Dam, China’s massive hydroelectric project, involved the movement of a mass of water so vast that it was capable of lengthening 0.06 microseconds Earth day. The Chinese dam is a unique case due to its magnitude, but it is just one of the tens of thousands of reservoirs that populate our planet. The overall impact of these reservoirs has now come under study. Shifting the poles. A new study has found evidence of the geological impacts that the construction of dams can have on a global scale. They observed that the construction of dams had caused a slight shift of the geographic poles of the planet, Geographic poles? As children we were probably taught that the geographic poles and magnetic poles of our planet were located at different points in their respective polar circles. Surely they would teach us that the magnetic poles tend to move slowly over time while the geographic poles remain static, forming the Earth’s axis of rotation. This is more or less true, but not entirely precise: geographic poles can also move. The reason is in the very structure of the Earth. Our planet is not a uniform block of rock but is made up of several concentric layers. While the outer layer is essentially solid, the inner ones are not. As if it were a mat on a swimming pool, the Earth’s crust “floats” on the mantle, which implies that it can move more or less independently, displaced by the physical forces applied in each case. Redistributing the mass. Forces that in turn depend in part on the distribution of the masses that we find in this superficial part of the planet, a distribution that is altered every time we introduce changes in the geography of our planet. These changes include the displacement of large masses of water into the swamps, water that under “normal” conditions would have returned to the ocean carried by the rivers on which we build dams. “As we trap water behind dams, we not only remove water from the oceans, lowering sea levels, we also distribute mass differently around the world,” explained in a press release Natasha Valencic, co-author of the study. 6,862 reservoirs. The team responsible for the study analyzed the impact of the accumulation of water in 6,862 reservoirs, an accumulation of water that represents twice the volume of the Grand Canyon of the Colorado. The team observed that between 1835 and 2011 this accumulation of water could be responsible for almost a meter of displacement in the Earth’s axis of rotation with respect to the planet’s surface. The displacement would be divided into two stages. The first between 1835 and 1954, in which the pole would have moved 20.5 cm towards the 103rd eastern meridian as a result of the construction of dams in Europe and North America. The second, between 1954 and 2011, would have been dominated by construction in Asia and East Africa, moving the pole 57 centimeters towards the 117th meridian west. Details of the study were published in an article in the magazine Geophysical Research Letters. More than reservoirs. The implications of these geographical changes are not extreme: after all, the tectonic plates do not stop moving at our feet despite the fact that their rhythms are usually slower. However, knowing these small movements can help us understand some of the geological dynamics and the impact of humans on them. “We are not going to fall into a new ice age because the pole has changed by around one meter in total, but it does have implications for sea level,” Valencic clarified.

“Lol, I have access”, the message from the engineer who uncovered the scandal

This weekend a soap opera has exploded that seriously threatens the first Made in OpenAI hardware, leaving an engineer with a long and successful career as an engineer in a bad light. Tan Tang (24 years at Apple and VP of product design for the iPhone or Apple Watch) and calls into question the security of Cupertino: Apple has led to court OpenAI for alleged theft of hardware trade secrets and breach of contract. what’s happening. Apple sums it up harshly in demand40 pages: “one thing is clear: at every level, from members of its technical staff to its director of hardware, and in coordination with business partners, OpenAI has been stealing trade secrets and confidential information from Apple.” Additionally, Apple alleges that former employees, specifically Chang Liu and Tang Tan, continued to access confidential Apple information after moving to OpenAI. Two former Apple employees, in the target. Striking is the case of Liu, a senior electrical systems engineer who, after eight years at Apple, left for OpenAI in January 2026. Apparently, Chang Liu kept his corporate laptop and discovered a flaw that allowed him to access Apple’s internal servers and download a collection of more than a thousand pages of technical files on unannounced technologies, features and products, including technical specifications and engineering presentations. “LOL, I discovered that I have access to the storage network, how fun”, wrote in an email to a former Apple colleague. For his part, Tang Tan, OpenAI’s current hardware director, is accused of using confidential Apple codenames during OpenAI’s hiring process, asking candidates to bring Apple hardware components to their interviews, and advising those abandoning Apple’s ship on how to evade the company’s security procedures. Why is it important. For OpenAI this is a blow that goes straight to its waterline, as it prepares to go public and launch its first device with AI. Sam Altman’s company will have to do and prove much more than the brief statements of its spokesperson, Drew Pusateri: “We are not interested in the trade secrets of other companies. We remain focused on developing innovative technology that empowers people around the world,” as reported by CNBC. For Apple, this lawsuit is an attempt to stop the incessant drain of talent that Cupertino has been suffering for a long year and that it has a fairly common destiny: OpenAI. Apple figures the disbandment of workers in 400 peoplewho would have abandoned the Cupertino ship bound for the company led by Altman. OpenAI has gone from being the company behind the most mainstream artificial intelligence models to becoming a potential direct competitor in hardware with its future first AI gadget. Context. Veteran Tang Tan had spent almost half his life at Apple and it is not an exaggeration: he spent 24 years there, where he became vice president of product design for iPhone and Apple Watch, with an essential role in their supervision. Then, he left and together with another Apple legend like Jony Ive, he founded io Products in 2024. In 2025, OpenAI bought io Products for 6.5 billion dollars in 2025. This is not the first time that OpenAI has found itself in court, which in fact has a few on intellectual property. The most popular is the one that has been pending with The New York Times since 2023, when the American media sued OpenAI and Microsoft for using their articles without permission to train AI models. In detail. In the lawsuit filed it is stated that Apple sent a letter in February to OpenAI to express his concerns, but received no response. Regarding its legal requests, Apple asks the court to prohibit OpenAI from retaining, exploiting or distributing its trade secrets and to force the return of all intellectual property allegedly stolen. As striking as the names and actions of the two former Apple employees are the absences: despite his leading role in the plot, Jony Ive is not accused of anything. What’s going to happen now. Now the trial enters a phase where Apple and OpenAI will have to share evidence, emails and internal documents between them, before a judge decides the case. Meanwhile, Apple is asking for precautionary measures to prevent OpenAI from continuing to use the information, as well as compensation and the return of all the allegedly stolen material. This request from Apple is critical because it could paralyze and even stop the launch of its AI device to redesign components or modify technical specifications or manufacturing processes if it is proven that they are based on Apple’s intellectual property.

Inheriting shoes seems like a great idea to save. Biomechanics and podiatrists are very clear that it is a mistake

In many families it is quite common to see how the older brother or sister grows and leaves some sneakers or boots that look practically new without being able to use them. Here the logic indicates that they can pass it on to the younger brother so that they can take advantage of the money that has been spent and not throw away something that a priori is completely functional. However, what on paper seems like an impeccable financial decision collides head-on with children’s biomechanics and podiatric health. A custom mold. The key to the problem is not in the exterior appearance of the shoe, but in its interior and in the sole. As explained Podiatrist Rebeca Prieto Riaño in a recent article in eldiario.es, an already worn shoe tends to be “molded” to the gait pattern of the first child. Here you have to understand that each person has a unique way of walking and distributing weight. With continued use, the shoe suffers from specific wear zones that end up acting like small invisible wedges, and when a second child puts on that shoe, their foot is forced to adapt to a shape and inclinations that are not their own. It’s a problem. This can significantly alter your stride, favoring everything from biomechanical problems to tendon and muscle injuries, as well as classic blisters or chafing due to inadequate support. It is a recommendation. Although there are no clinical trials today, direct evidence comes, above all, from clinical guidelines and the consensus of specialists like the document Children’s Footwear Advice of the Suffolk Podiatry Paediatrics. But we do have different biomechanical studies that show that footwear modifies the parameters of children’s gait, including speed, step length, ankle and knee ranges of motion, and impact pattern. The biomechanics. Specifically, we see it in a meta-analysis published in 2011 that already concluded that shoes irremediably affect children’s gait. Added to this are more recent experimental works, such as a study published in Gait & Posture in 2023, which demonstrate how asymmetric shoe heights induce reactive changes in gait kinematics and muscle activation. It goes further. In addition to the mechanics of gait, there is a dermatological factor to take into account, since pediatric podiatry guides advise against second-hand footwear due to the risk of infections. Sharing closed shoes that have accumulated sweat and humidity greatly facilitates the transmission of skin pathogens, especially dermatophytes, which are the fungi that cause athlete’s foot. The cotton test. Does this mean we should automatically throw away any shoe our oldest child outgrows? Not necessarily, since experts in children’s orthopedics and podiatry establish footwear that has had residual use as an exception. For example, shoes for a wedding that were worn one afternoon, or wellies that the child wore three times before his foot grew, can be inherited. The essential condition is that there are no signs of adaptation to the previous step. In Xataka | Walking almost barefoot is the new wellness trend: this is how barefoot has arrived everywhere

Lovecraft created it as a joke, but the Necronomicon has existed in many forms and is, in fact, back in bookstores.

In 1922, a young writer from Providence He introduced into a story a cursed book that did not exist in any library in the world. A century later, that private joke has generated real sects, complaints of plagiarism among New York occultists and a new Spanish edition of more than 600 pages. The Necronomicon was never written, but it continues to be published, although the insistence with which it returns again and again, of course, suggests that some real mystery lies within its pages. Neonomicon. Duomo Ediciones has launched this summer a new Spanish edition of the Necronomicon, the book of black magic whose pages torment the protagonists of dozens of stories by both Lovecraft and many of his disciples. The volume brings together in 648 pages almost all the mentions of the Black Book spread throughout the Lovecraftian narrative, with illustrations by Greta Grendel and without ever disguising that we are dealing with a voluminous fictional artifact. The selection is carried out by the Italian Giuseppe Lippi, who divides the material into three blocks (the dream, the myth and the terror) and signs the prologue, placing the Necronomicon alongside other impossible books of literaturelike Pierre Menard’s ‘Don Quixote’ conceived by Jorge Luis Borges or ‘The King in Yellow’ by Robert W. Chambersl. The book is a true atlas, a map of all the times the Providence writer decided to quote, in passing, a book that was never one of his plans to write. History of the book that never existed. Howard Phillips named the Necronomicon for the first time in ‘The Hound’, a story written in 1922 and published in the magazine ‘Weird Tales’ in 1924, although a year before he had already cited its supposed author, the Arab Abdul Alhazred, in ‘The Nameless City’, where we could read the famous couplet about the death that can die. In 1927 he developed the joke with ‘History of the Necronomicon’, an apocryphal chronology that places the original writing of the text in 8th century Yemen, with a translation into Greek around the year 950. The author never hid the invented nature of the book: in a letter to Willis Conover he wrote “there was never any Abdul Alhazred or Necronomicon: I invented those names.” Lovecraft continued to name the book throughout his work. In ‘The Feast’ (1925) it appears kept in the fictional town of Kingsport, in a Latin translation attributed to the scholar Olaus Wormius and placed alongside other “legitimate” occult titles of the time. In ‘The Case of Charles Dexter Ward’, written in 1927 and published posthumously in 1941, it is the witch Joseph Curwen who keeps his own copy, and the author will mention Yog-Sothoth for the first time. The couplet cited in 1921 reappears, this time explicitly identified as a textual quote from the Necronomicon, in ‘The Call of Cthulhu’ from 1928. Necronomicon superstar. The story in which the book achieves the greatest prominence is ‘The Dunwich Horror’, from 1929. There we will read the most extensive quote ever published by Lovecraft, taken directly from its pages. In the story, Wilbur Whateley searches in vain for a complete copy in the Miskatonic University library; The librarian Henry Armitage denies him, and Whateley is torn to pieces by a guard dog while trying to rob him. Two years later, in ‘He who whispers in the darkness’, the story alludes to the vast chaos that is hidden under the name of Azathoth, protected for centuries by the Necronomicon itself. That same year (1936), in ‘At the Mountains of Madness’, the protagonists have already read it before the expedition begins, and it is in its pages where they find the first clue about the shoggoths. Real Necronomicon. Fiction became a real commodity in 1977, when the publisher Schlangekraft published the so-called Simon’s Necronomicon, a pastiche of Sumerian and Babylonian mythology sprinkled with names taken from Lovecraft’s stories. Behind the project was Herman Slaterowner of the New York esoteric store The Warlock Shop, tired of explaining to his customers that the book of his youthful fantasies did not exist in any library. The actual authorship is usually attributed to the writer Peter Levenda, hidden under the pseudonym Simon. When the book jumped from the limited print run of hardcover to the Avon Books paperback edition, William S. Burroughs signed a text of accompaniment in which he asked that “the secrets of the centuries be revealed”, convinced that hiding them would only benefit those who already controlled them privately. There had been talk for some time about the real Necronomicon: the British ceremonial magician Kenneth Grant, Aleister Crowley’s former secretary, maintained that Lovecraft had unknowingly absorbed teachings from real occult sects active in New England, and that his ancient gods were not pure invention but manifestations of forces that a well-versed practitioner could invoke. You go to the cinema. The book survived the death of its creator thanks to the most acrobat horror films and comics. In Sam Raimi’s ‘Terrifyingly Dead’, the first sequel to his ‘Infernal Possession’, the Necronomicon Ex Mortis appears recorded on a cassette tape that awakens a forest spirit. And Alan Moore and Jacen Burrows dedicated twelve issues of ‘Providence’ to reconstructing (among other things) the origin of the book, as the culmination of a trilogy that began with ‘The Courtyard’ and ‘Neonomicon’. All rehashes and variants that, paradoxically, have not annihilated the legend of the dark volume, but rather have kept it more alive than ever.

Denmark was building the world’s largest wind farm when a 400-year-old sunken ship was found

Although we have been watching for years how China builds renewable mega-facilities like It is on the Tibetan plateau or this other colossal wind farm with 136 wind turbines 100 kilometers offshoreis not the only country with great ambitions to generate clean energy. Without going any further, Denmark is in the preliminary stages of setting up the largest offshore wind farm in the world, Hornsea 3. But for now this installation will have to wait because in the middle of prospecting work, they have found gold. Or rather, lead: the one reveals the existence of a wreck with a cargo of lead ingots. The discovery. This huge wind farm is being installed by the energy company Ørsted, in the North Sea, off the coast of Yorkshire. There, about 120 kilometers from Norfolk and about 40 meters deep, they were doing safety surveys of the seabed in search of possible unexploded ordnance from the Second World War when they came across a 17th century shipwreck. The curious thing was the trigger for such a discovery: what appeared on the monitors were three lead ingots weighing 70 kilograms each that were still stacked in their original position. There were also some remains of wood and some hull of the ship that transported them. Thanks to the mark that the smelter left on the ingots, it is possible to try to trace their origin, in this case of hypothetically linked to Derbyshire. Why is it important. Because it clearly evidences the early modern English lead trade. In this case, the wreck found is directly on the route that linked Hull with the Netherlands through the North Sea. Context. At that time and as the MSDS Marine explainsEngland produced large quantities of lead, especially in the mines of Derbyshire and the Peak District. From Hull and London it was exported to other locations, such as Amsterdam and Rotterdam. Before we discovered the toxic effects of lead, this element was commonly used for pipes, cookware, weapons, and other products. Transforming it into ingots made it easier to transport as merchandise. A curiosity: the heritage legislation of the United Kingdom requires archaeological studies to be carried out before the construction of this type of infrastructure and thank goodness, because in British offshore wind farms in recent years a roman anchor has been found. In detail. More specifically, the three recovered lead ingots have three different engraved markings (“IS”, “EB” and “H”). These signs are reminiscent of those found in the Kennemerlanda Dutch East India Company ship sunk in 1664 near the Shetland Islands. For this reason, in this preliminary phase the research team holds that the ship was probably Dutch and was heading back to the Netherlands loaded. Yes, but. At the moment, almost everything is hypothesis: a deeper investigation is needed to determine the origin of the ship and a more precise dating beyond the “17th century.” Furthermore, the geological origin of lead has not been analytically confirmed either.

The heat changes your mood. An Egyptian understood this 40 years ago and designed a town that “sweated” to cool down

The heat doesn’t just make you sweat: it also changes the way you behave. think, sleep and even relate. For decades we have responded to that problem by filling houses air conditioning. However, long before that was the solution, an Egyptian architect came to a very different conclusion: if heat alters our well-being, perhaps the first thing to change is not the machine, but the building. Thus was born an architecture that seemed to “sweat” to stay cool. The “great” discovery. The life of Hassan Fathy changed in 1941 during a visit to a small Nubian village in the Upper Nile. There he found something that modern architecture had forgotten: houses built with mud that seemed to emerge from the landscape itself and maintained a pleasant temperature even under the scorching Egyptian sun. While the rest of the world associated progress with concrete, steel and glass, Fathy began to wonder why those humble buildings managed to coexist with the climate. far better than modern buildings. Heat is a psychological problem. Fathy understood something that today science relates to heat waves: an uncomfortable home not only consumes more energy, it also affects to rest, to humor and the quality of life. His obsession was never to build spectacular buildings, but rather spaces where the air itself will work in favor of those who lived inside. To achieve recovered centuries of forgotten knowledge: interior patios, narrow streets, lattices, thick adobe walls and systems capable of moving air naturally without the need for engines. Hassan Fathy Buildings that seem to sweat. One of the most striking elements of his designs were wind catchers and evaporative cooling systems. In some buildings he carefully oriented the homes with respect to the sun and the prevailing winds to guide the air inside. In others it made that current pass on wet coal or wet surfaces, causing cooling by evaporation very similar to human sweat. Just as our body uses water to dissipate heat, Fathy’s architecture used mud, humidity and circulation of air to reduce the interior temperature without wasting electricity. Roof and dome of the Kourna Mosque seen from the minaret The modern takes another path. While Fathy advocated mud, adobe and local solutions, much of the Middle East began to copy western models designed for very different climates. From Baghdad to Benghazi, large concrete blocks, wide avenues and glass facades appeared that eliminated shadow and trapped heat. For Fathy that was a misconception: It made no sense to build buildings that first generated a thermal problem and then solved it by installing air conditioning. New Gourna City The best example: an entire city. This is how we arrive at what was his great laboratory: New Gournaa town built near Luxor during the 1940s to relocate hundreds of families. There he applied all your ideas: adobe houses, private patios, winding streets, Nubian vaults, wind collectors and spaces designed according to the path of the sun during the year. Its objective was not only to make housing cheaper for the poorest, but to demonstrate that it was possible to build entire communities. adapted to the climate and not the other way around. New Gourna The problem was never the architecture. Nueva Gourna ended up becoming one of the great paradoxes of the 20th century. Many neighbors covered the wind collectors, closed the patios and replaced the adobe vaults with reinforced concrete because that seemed “more modern” to them. The result was exactly the opposite what they were looking for: homes that are hotter in summer, colder in winter and much more dependent on mechanical systems. Fathy had anticipated it years before: when prosperity comes, the poor tend to imitate the houses of the rich, even if those houses perform worse in their own climate. The New Gourna Mosque The man who was ahead of his time. While his colleagues were building Western-inspired glass skyscrapers, Fathy was seen in Egypt as little less than like an eccentric determined to return the country to the past. However, outside its borders it began to gain recognition as a pioneer of sustainable architecture and received some of the profession’s highest international awards. As time goes by, your ideas they ended up influencing in universities, international organizations and entire generations of architects interested in bioclimatic construction. The answers from 80 years ago. Today, with cities increasingly hit by heat waves, many of the solutions that good Hassan Fathy defended are once again in the spotlight. the center of the debate architectural. Natural materials, passive ventilation, patios, lattices or wind collectors reappear in projects that seek reduce energy consumption without giving up comfort. Even UNESCO works to restore part of New Gourna and preserve its legacy. Not because it represents a historical curiosity, but because it contains a surprisingly current idea: perhaps the most intelligent building is not the one that incorporates the most technology, but the one that makes the heat never comes to become an enemy.

Men over 45 have 31% more genetic mutations than those under 30

Historically we have heard that only women have to worry about their biological clock when it comes to having children, meaning that the sooner they get pregnant, the better. The classic biological argument was based on the finite ovarian reserve and the cellular aging of the oocytes. But the evidence has been warning for years that the clock is ticking for men. A new study presented by the IVI Foundation during the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology has put a figure specific to male reproductive aging. This indicates that men over 45 years of age have 31% more mutations in their sperm compared to men under 30. A cell factory. Unlike oocytes, which are formed during female embryonic development and remain in a state of latency until ovulationsperm are produced continuously from puberty. This implies that the stem cells from which the sperm come are constantly dividing, causing even a seventy-year-old man to continue producing sperm. In cell biology, each division is an opportunity to make a copying error in DNA. And although cellular repair mechanisms are amazingly efficient, they are not perfect. Over the decades, errors accumulate and these genetic alterations that were not present in the parents but appear in the offspring are known as de novo mutations. They warn you. Science has been documenting this phenomenon for more than a decade and we have an example in an article published in Nature in 2012 that already established that approximately 80% of mutations of note They come from paternal genetics. Furthermore, the researchers estimated that the offspring’s genome acquires between 1 and 2 additional de novo mutations for each year that the father’s age increases. Now the new study confirms these data. Selection of sperm. The 31% increase in mutations is not solely due to a passive failure in DNA repair due to the simple wear and tear of age. This is where a fascinating, microscopic evolutionary mechanism operating in the testes called “selfish spermatogonial selection” comes in. In this case, some of the mutations that occur in sperm stem cells are not neutral, but rather confer a proliferative advantage to the cell itself. Specific mutations, such as those that occur in the gene FGFR3 or in the RAS signaling pathway, cause these mutated stem cells to divide faster and survive better than neighboring healthy cells. Over time, these mutated “clones” end up dominating large areas of the testicle, producing an increasing proportion of sperm carrying the mutation. Relative risk. The mutations de novo associated with advanced paternal age are strongly linked to the appearance of rare diseases of monogenic origin in offspring, such as achondroplasia, Apert syndrome or Costello syndrome, in addition to showing complex genetic correlations with neurodevelopmental disorders. However, the absolute risk of a father over 45 years of age conceiving a child with one of these severe pathologies remains statistically very low, specifically less than 0.5% in those over forty years of age. All of this means that the mutational increase is undeniable at the genomic level, but the probability that these mutations directly impact a critical gene and result in a congenital syndrome remains rare.
