Japan is reconquesting at full speed the chips industry. He has just manufactured his first 2 nm transistor

by

Rapidus corporation It has just officialized A very important achievement: it has successfully manufactured its first 2 nm transist. It is very unusual for a company based just three years ago already stepping on the heels to the three giants of the semiconductor production industry: TSMC, Intel and Samsung. These companies plan to start Large scale manufacturing of 2 nm chips During the second semester of 2025, and, although Rapidus is not yet ready to manufacture this type of integrated circuits, the speed with which it is reaching intimidated milestones. This last company is with Tokyo Electron and JSR Corporation the best option in Japan for recover relevance which he had in the semiconductor industry in the 80 They monopolized in 1988 Nothing less than 50% of the chips industry. However, today none of these companies is positioned among the leaders of a sector dominated with iron fist by Taiwanese, American, Chinese, South Korean and German companies. Rapidus is fulfilling its promises one by one The latest generation semiconductor production plant that this company has put up in northern Japan, in the city of Chitose (Hokkaido), started the wafer processing tests in a pilot line. The directive plan of this factory is to start large -scale production of 2 Nm semiconductors in 2027, and is perfectly credible. In fact, the milestone that has just announced invites us to anticipate that they could even manufacture these chips massively before the end of 2026, although it is only a conjecture. Rapidus is a very young company. It was founded on August 10, 2022 by the Japanese government with an initial capital of 7,346 million yen (Something less than 46 million euros) contributed by, and here comes the interesting, Sony, Toyota, Nec, Softbank, Kioxia, Denso, Nippon Telegraph and MUFG Bank. The initial capital invested in the constitution of this company is not very bulky, but there is no doubt that the companies that participate in it They have an indisputable relevance in the sectors of technology, automotive and telecommunications. The purpose of Rapidus is to tune an automated production line that will be specialized in the manufacture of 2 Nm chips for AI applications The relevance of this organization, in any case, lies in the role entrusted to him by the government currently led by Shigeru ishiba. And, as I mentioned a few lines above, this is the company with which Japan aspires to recover competitiveness in the semiconductor manufacturing industry that had three decades ago. Its economy is at stake. In fact, this Asian country began to deploy its strategy to reinforce its integrated circuit industry more than two years ago, so the first results begin to see the light. What is causing the new Rapidus factory to monopolize the looks of the semiconductor sector is that, According to Atsuyoshi Koikewhich is the president of the company, will be completely automated. Its purpose is to resort to robots and artificial intelligence (AI) to set up An automated production line which will be specialized in the manufacture of 2 Nm chips for AI applications. Its plan consists, in short, to produce integrated circuits faster, with a lower and more quality cost. To manufacture these semiconductors, equipment of extreme ultraviolet lithography (UVE) produced by the Dutch company ASML, and practically all manufacturing processes are automatic. However, the tests of test and validation, interconnection and packaging of the chips are still largely carried out manually in most manufacturing plants. According to Rapidus, its automation technology of all these processes will allow you to reduce the delivery time of your chips by 66% compared to the times they usually offer TSMC and Samsung.

There are regions of Spain that are building more houses than homes. And not even the wrings even go down

by

That Spain suffers A housing deficit It is no novelty. Just as it is not that construction is unable to advance to the rhythm of formation of new homes. ACI, the Real Estate Consulting Association, has just published however A study that reveals something curious: there are 11 provinces in which it is built faster than new homes are constituted. The striking thing is that, although a priori that ‘surplus’ suggests less pressure in the market, its prices do not soften. On the contrary, they grow, as in the rest of the country. Asturias leaves A good example. A fact: 134,649. That is the real estate deficit that Spain accumulated last year according to The last report DE ACI, the Spanish Association of Real Estate Consulting. In this way it may sound abstract or too theoretical, but the data reflects something very simple: the mismatch between the number of housing and the new homes created throughout 2024. While the former stayed at 86,609, the seconds, which grow at much higher speed, amounted to 134,649, aggravating the housing shortage that Spain suffers. What are the reasons? “This lag shows the structural difficulties facing the promoter sector in Spain, derived from both the shortage of finalist land and the increases in construction costs, normative restrictions and delays in urban processing,” concludes The report, which recalls that the 86,609 houses delivered are also below the forecast of new homes. The 2024 deficit is also added to the one registered in recent years and that ACI estimated at 349,934 Since 2020. The association is not the first to warn of the difficulties that Spain is being found to adjust the creation of housing to the formation of New homes. In May the Bank of Spain estimated the lack of housing in Between 400,000 and 450,000 units in the period 2022-2024, an elevated figure, but that moves in any case of the huge hole of 600,000 that indicated in its 2023 report. Analyzing the map in detail. The most interesting thing about ACI study It is not so much the photo at the national level as its details, the information provided by each community. The reason? Although in most cases the delivery of housing was unable to cover the creation of new homes, enlarging its residential deficit, the agency identified 11 provinces in which the result was the inverse. That is, the volume of built houses covered (and exceeded) the creation of households. That is the peculiar situation in which Asturias, Burgos, Cáceres, Ciudad Real, León, Palencia, Salamanca, Soruel, Teruel, Valladolid and Zamora were found, to which the autonomous cities of Ceuta and Melilla are added. Although they got off the general trend of Spain and closed 2024 with ‘residential surplus’, their effect was barely felt on the national balance. Among those 13 territories there are only a plus of 5,005 homes above the houses created. Province Housing delivered New real homes Difference 4th quarter price of 2023 (€/m2) * 4th quarter price of 2024 (€/m2) * Asturias 1.820 257 1,563 1,347.2 1,473.1 Burgos 808 462 346 1,169.3 1,212.3 Cáceres 1,344 267 1,077 849.7 873.4 Ceuta 71 41 30 1,827.3 1,937.5 C. Real 722 655 67 712.5 725.5 Lion 403 62 341 889.8 914.8 Melilla 182 150 32 1,827.3 1,937.5 Palencia 373 -46 419 931.1 954.7 Salamanca 485 220 265 1,218.1 1,230.7 Soria 460 247 213 939.8 968.7 Teruel 305 267 38 819.2 891.4 Valladolid 1.116 970 146 1,309.7 1,374.6 Zamora 152 -316 468 804.4 836.4 National Total 86,609 221.258 -134,649 1,842.3 1,972.1 *The prices are extracted from the official registration of the average appraisal value of the free housing that the government publishes quarterly Why is it interesting? So it reveals to us from the market. Although there are many buyer profiles (investors, families interested in a second residence or people who want to take a property and then dedicate it to the holiday rental), which in those 11 provinces (more Ceuta and Melilla) the delivery of homes exceeds the creation of households suggests a lower pressure of the demand on supply. And that, a priori, should move to market prices. Asturias leaves an especially interesting case. According to Data published by ACIthere last year 1,820 homes were delivered and 257 new real homes were recorded. The balance remained in green numbers with a positive balance of 1,653 homes. The second example is found in Cáceres (1,077), where he accounted for 1,344 homes delivered to 267 new real homes. And what happened to prices? They grew up. Despite this lower pressure in the market and that there was no mismatch between supply and demand for new homes, the house continued to take care. And that tells us about the key weight of other factors, such as costs or demand diversification. Government data on the appraisal value of the house shows that at the end of 2023 the square meter (m2) of free housing in the Principality was at 1,347 euros. A year later it was already at 1,473. The increase was therefore 9.35%, not very different from 9.43%of Madrid and several points above the state average, of 7.05%. If we turn to idealist the photo is similar. The real estate portal estimates that in December 2023 the residential M2 for sale cost in the Principality 1,371 euros and in the same month last year it was already 1,471. In summary: an increase of 7.29%. In THE CASE OF MADRID (Province) There are differences with respect to official appraisal data. During the same period it has passed from 3,208 to 3,771, which leaves an increase much greater than that of Asturias, of around 17.5%. A rising market. The Principality data does not surprise if one takes into account that its real estate market is on the rise. The latest data from the General Council of Notaries, published recently by The voice of AsturiasThey show a 19.9% growth in housing sale operations and an year -on -year increase in the price of 7.7%, although their … Read more

They already use a mixture created by algorithms for their data centers

by

Goal has used a concrete mixture designed by algorithms in one of its data centers. According to the companythis formula promises to be more sustainable, faster to apply and has been developed with open source tools. With this approach, not only is it sought move towards zero emissions: Also accelerate the construction of infrastructure that grow to time, As the data center that is raising under provisional structures demonstrates. Invisible concrete weight. Few materials are as omnipresent as concrete. It is used on roads, bridges, homes … and also in data centers where a good part of our digital life is housed. The problem is that manufacturing its components, especially cement, generates a huge amount of CO2. The World Economic Forum indicates that It represents about 8% of global emissions. Goal has proposed to reduce that footprint without compromising the resistance or work speed. And that’s where his new model enters. An AI that does not create chatbots, but mixtures. To develop this system, goal was allied with Amrize – One of the world’s largest cement manufacturers – and with the Urban-Champaign University of Illinois. Together they have created an AI model that proposes concrete compositions. The model is based on Bayesian optimization And it is built with Botorch and AX, two open source tools developed by the goal itself. A slab test in the Rosemount Data Center The challenge was not minor: each mixture involves combining different types of cement, aggregates, water, additives and supplementary materials such as scum or flying ashes. The exact proportion, its origin or even the time of the year can alter the result. Traditionally, they explain, validate a new formula has been for weeks. With AI, this process accelerates because the system learns from the previous data, proposes new promising combinations and refines its predictions after each test. Implementation of the concrete formulation generated by AI in the data center From the laboratory to the field. One of the first large -scale validations was made in the data center that Meta builds in Rosemount, Minnesota. There, the contractor Mortensen applied the new mixture in one of the building’s support slabs. The objective was not only to check its resistance, but also its workability and the final finish: these slabs must be perfectly smooth and durable. The result, according to the firm, exceeded all technical standards. The formula designed by AI not only met the demands of resistance and cure, but also behaved well into work: it was poured without problems and offered an adequate surface. After two iterations, and with minimal human adjustments, the model had generated a recipe that improved the usual industrial formulas in speed, resistance and potential for emission reduction. An open model. The system developed by goal is not a commercial product or a closed tool. The company has published the code, data and technical approach in An open github repository called SustainableConcrete. The idea is not to keep the formula, but share the method: a way of applying artificial intelligence to concrete design that can adapt to other works, suppliers or materials. Touch wait to know if we will see more initiatives like this. This could facilitate the adoption of alternative mixtures in a variety of constructions. As we have seen, goal has not invented a new material. What he has done is to use AI to find new concrete formulas.

The most unexpected object has become the last battlefield of Catalan independence for a detail: the letter e

by

A letter. The E. thus, in capital letters. And a fine. Capital for some if we consider that it is about paying 200 euros for covering a letter. Because that is the sanction that those who cover in Catalonia are receiving the letter E of the registration of their cars. The same that identifies the plaque with Spain. A lyric. And what lyric is it? The E. of “Spain”, “State” and “confrontation”, to give only some examples. At least for those who consider that this letter in their enrollment is an act of submission to the Spanish State and, therefore, is a cause for political confrontation. That letter that some Catalan independence disappears from their tuition to replace it with the CAT letters, next to a SENYERAas a political claim or small subversive act before what they consider the submission of Spain in the region. It is not new. The confidential collects the return of this way of acting by some Catalan independence. But this act of protest is not much less new. At the end of 2024a Catalan was fined for this reason, when considering the Mossos d’Esquadra that had manipulated the registration, which is considered a serious infraction that entails a sanction of 200 euros. But these attempts to replace the license plates either since then. Already in the last decade You can find some publications that point out this way of acting by some drivers. In some yes the European Union flag was maintained. However, it has been in the last two and three years in which the most noise has been generated. The Galician case. But it has been in the last three years when the phenomenon has taken special relevance. In 2024 a driver complained in social networks of having received the aforementioned fine. In the answers there were those who assured that carrying the CAT on the registration was not illegal. The origin must be found in Galicia. There, Bieito Lobeira, Secretary of Organization of the Galician Independence Party BNG, was fined for covering the E of Spain by a GZ in reference to “Galiza”. After various resources, Lobeira won the procedure because it was pointed out that the small modification did not prevent the correct reading of the registration. To this are grabbed those who act in this way, such as David Miñana (ANC leader) either Jordi Cabré (writer). The matter is slippery because in article 49.4 of the General Vehicle Regulations the following is specified: “It is prohibited that the registration plates be placed, registered or painted ornaments, signs or other characters other than those indicated in Annex XVIII, including advertising inside them (…) It is prohibited that in the anterior and posterior parts of the vehicles they will be placed unauthorized complementary plates or fix or paint marks or distinctive marks or distinctive Difficult readability or may induce confusion with the regulatory characters of the registration plates “ However, in the Traffic Law, where the serious sanctions (200 euros) are reflected, it is specified that the following compliance is sanctioned: “Failure to comply with the obligation of any driver to verify that vehicle registration plates do not present obstacles that prevent or hinder their reading and identification” Lobeira won when the judge understood that he took part in his appeal that the GZ letters did not prevent or hindered the reading and identification of the registration. 25 years. In the newspaper AraThey point out that this fight for the letters of the registration has been living for a quarter of a century. In 2000, the Spanish registration plates changed. They adapted to the obligation to carry the letter E and the flag of the European Union for the identification of a vehicle outside the country of origin. However, the government of José María Aznar also eliminated the references that existed to the regions. Before the year 2000, Spanish registrations were made up of one or two letters that referred to the province, four numbers and two additional letters. Already then The nationalist parties and the United Left complained about the absence of the autonomic badges. Already at that time some media and independence groups they encouraged this little protest actiondistributing stickers to incorporate into registrations. And in Europe? The truth is that in Europe there is a good handful of countries that have maintained regional badges despite having to change the registration plates to adapt to European regulations. In France, in Germany or in Italy Shields, letters or any other badge that specifies the region of origin of a vehicle are maintained.

For years we were who we called to ask for information. Now Google’s AI calls for us

by

Imagine you are looking for a hairdressing for your dog. You do not have time to call, compare prices or review reviews one by one. But Google yes. His artificial intelligence is in charge. Call for youconsult availability, ask for prices and give you the answer, all without you said a single word. That is exactly What has begun to activate Google: A new function within its search engine that allows the system to contact local businesses in your name. It is not an independent app or an isolated experiment: it appears directly in the search results, under a button that says “Have Ai Check Pricing.” An AI that acts in your name, without changing your way of searching It is not necessary to learn commands or configure anything special. Press the button, answer a series of questions and the system is responsible. Speak for us, collects data on prices and availability and returns them organized. We continue using the search engine as always, but with an AI that is no longer limited to responding: it begins to do things. An interesting point is that companies can control this function from their business profile, which guarantees that they have control over whether or not to receive this type of calls. For now, this capacity is only available in the United States. Of course, Google has not mentioned concrete plans for its deployment in the European economic space or has given dates about its arrival in other regions. If something is clear is that Google is no longer made up of offering links. He wants to execute tasks. Organize data, reason, investigate … And now also contact third parties. Google is also updating a parallel solution called Ai mode. Now it works with Gemini 2.5 Proits smartest model, and the Deep Search tool, capable of making deep searches. Both improvements are only available to those who have registered in the AI Mode experiment through Search Labs, and require a subscription to the pro or ultra plans. These novelties arrive just when the launch of Chatgpt agentsthe new openai system that operates on a virtual computer and Execute real tasksstep by step.

An Voyager 2 mission review has revealed that Uranus is not as described

by

Uranus, the planet that orbits side, has always been the weirdo of our solar system. Since NASA’s voyager 2 probe survived him in 1986astronomers have dealt with a disconcerting mystery: unlike their gaseous Jupiter, Saturn and Neptune, Uranus seemed not to have an important internal heat source. It was, in appearance, an inert and energetically dead world. But that idea has just jumped through the air. A little context. In January 1986, the Voyager 2 probe became the first and only ship to visit Uranus, giving us the most iconic images of the planet and the data that laid the foundations of everything we know about him. One of the most important was its energy balance, the heat it emits with respect to the sun. The giant planets have an immense mass, so they retain a considerable amount of the heat of their formation and release it over billions of years. This internal heat flow is evident in Jupiter, Saturn and Neptune. However, the Iris instrument of Voyager 2 told a very different story about Uranus. According to a 1990 study, the planet issued an almost identical amount of energy to what it received from the sun: the internal heat flow was statistically indistinguishable from zero. Uranus thus became the anomaly of the Solar System: an ice cream giant that, for some reason, had cooled much faster or formed in a completely different way from the other planets. I wasn’t dead. Nor of Parranda. A New study led by researchers from the Houston University It has finally resolved the mystery. After analyzing decades of data, scientists have shown that Uranus does emit more heat than he receives from the Sun. It is not the inert planet we thought, but a dynamic world with an internal engine That, although modest, is very present in the energy balance. The error was not in the measurements of Voyager 2, but in the interpretation of a single snapshot over time. This is where the new study led by Xinyue Wang and Liming Li, from the University of Houston. Instead of based only on the overflow of 1986, his team compiled and analyzed data from a much longer period (from 1946 to 2030), covering almost a complete orbit of Uranus, which lasts 84 terrestrial years. Uranus is a planet of extremes. Its rotation axis is inclined 97.7 degrees, so it basically rolls on its orbit. Combined with a remarkably long orbit, it causes extreme stations that last about 21 years each, with a hemisphere bathed by continuous sunlight while the other remains in an icy darkness. The researchers discovered that this seasonal cycle is the key to everything. The solar energy that absorbs the planet is not constant, but varies significantly throughout its year. The 1986 analyzes, made near the winter solstice of the northern hemisphere, did not capture the complete image. By averaging the energy balance throughout the orbit, the results are unequivocal: Uranus consistently emits 12.5% more energy than he receives from the sun. Not so weird bug. Uranus now fits much better in the formation models of giant planets. It has an internal engine, although it is weaker than that of its neighbors, which suggests that its evolution was more similar to that of the rest of what was thought. This finding not only changes our understanding about how giant planets are formed and evolved, but also arrives at the right time, when Both NASA as China prepare missions To visit it. If the question is why Voyager 2 obtained such a misleading image of the planet, the answer is simply bad luck. In the days before the 1986 overfather, the Sun bombed Uranus with An unusually powerful geomagnetic storm. This phenomenon compressed the magnetosphere of the planet, which caused the ship to capture data in a day of extreme conditions.

The public sector is an oasis of stability against unemployment. That is why 52% of workers consider opposing

by

In Spain, public employment has become a increasingly valued option For millions of people. Precariousness and job instabilitytogether with the problems to which Young people face and greater than 55 To find a job in the private sector, they are causing many people in precarious or unemployment situation to choose to prepare oppositions as a professional alternative. In A stage With 2,789,200 of people in unemployment, it is not surprising that more than half of the active population (about 12 million people) has thought of opposing seeking the security of a employment and stable salary in the public sector. The Public Employment Offer for 2025. The Government has already published the Public Employment Offer (OEP) by 2025, which includes a total of 36,588 places available. These vacancies include positions for state security forces and forces, as well as for the armed forces. Of the total, 27,697 places are new and 8,891 internal promotion. The vast majority of places, 70% (26,889 places), are intended for the General State Administration. In addition, 10% of vacancies (2,610 places) are reserved for people with disabilities, thus expanding opportunities within the public sector. Unemployment as an engine to oppose. Currently, more than 2.7 million people are unemployed in Spain, many of whom face serious difficulties in returning to the labor market in the private sector, either because they are too young and not meet the experience requirements, or for being over 55 years old. According to Report data ‘The weight of the opponent in Spain in 2025’ that the opposition formation portal elaborates every year, 48% of the unemployed between 18 and 55 years are preparing an opposition or intends to do so soon. If those who have already opposed in the past are included in the strip, the percentage amounts to 68%. The quarry of officials. The study reveals that the unemployment figures of the different autonomous communities are inversely proportional to the percentage of the active population that arises or is already preparing an opposition to one of the public employment squares. Thus, Extremadura, with a 16.60% strike According to EPA data Of the first quarter of 2025, it is the one that has prepared the highest percentage of the active population or is preparing an opposition with 48% of its population in order to work. Murcia follows, with a 12.83% unemployment rate, which records 43% of its labor mass with the intention of opposing, drawing in that figure with Castilla y León. At the opposite end, communities with less interest in opposing in relation to the total of its active population is Catalonia (19%), followed by Madrid (21%) that tied with Valencia and the Balearic Islands. How many people are? These percentages, taken to absolute numbers, assumes that 6,779,344 people are preparing to oppose At the moment or have recently opposed presenting themselves to the Latest calls. The data reveal that 9% of the people who are currently opposing a year ago. Of these, 67% had never opposed before. Which implies that the public sector is attracting a greater number of employees who would not have considered developing their career as a public official. 5,386,328 people plan to oppose in the near future, so they could participate in the call for oppositions that have just made public, or will do so for the call of 2026. In total, 52% of the active population, about 12,165,672 people are preparing, they are preparing or intention to prepare an opposition shortly, against 48% that they do not intend to do so. Official, but where? The results of the study slide that people who are opposing today do so To cover a place for the administrative or auxiliary body and for positions in health or education. The results are similar among those who have expressed their intention to oppose in the near future, the most quoted administrative places being. The main difference between those who plan to oppose and who is already doing it, we find in the aspiration of the new opponents for presenting themselves to a postal square, which almost quadruples.

It is on the northwest facade of the enclosure and just at the time that there will be many events (about seven or eight in the afternoon) the sun will be putting on. This screen we have not been able to see it on because they were still installing it, so we cannot judge how it looks. Visuals will be projected in it to announce which event or game will have that day. Screens inside and out The videomarker. Within the sand is the jewel of the crown: a videomarker with 250 square meters of surface that, according to LG, has the highest resolution in Europe. It is in the center of the pavilion and forms four screens, but as it has the rounded edges and the image they project is continuous, it gives the feeling that it is a single panel that wraps the entire structure. In addition, in the inner face there are two more screens in which information will be seen from the basketball matches that are held. More screens. There is no thing left, the interior of the Roig Arena is literally lined on screens (see the first photo). There is a kind of band that they call ‘Ribbon LED’ that surrounds the stadium and separates the lower stand from the superior. And there is even more. Inside is also the largest videowall in Europe, with an area of 500 square meters. Both the Videowall and the Ribbon and the videomarker do have seen them on and has surprised us with the sharpness and luminosity. Folded and deployed bleachers Two ages. The enclosure has a particularity and that is that the capacity is variable. You can house 15,600 people in Basket mode and up to 20,000 in concert mode. This is achieved with a retractable bleachers system in the first level. In a basketball game they will be deployed, creating one more level of seats that extend to the edge of the field, while in the concerts they will fold them so that they are hidden on the sides and the track is larger. Investment. The idea of making a new pavilion for Valencia Basket years ruminating And finally Juan Roig confirmed that he would build an enclosure with a capacity for about 15,000 people. In 2018 He traveled to Berlin to know the Berlin Arenastadium in which the project was inspired, and the works began in 2020. The total investment in the enclosure will be, according to its general director, more than 300 million euros And there is already date for its inauguration: on September 6. Basket and more. In addition to being the new home of the Valencian team, which leaves the mythical (but quite outdated) La Fonteta PavilionRoig Arena was also conceived as a space for concerts and shows. In fact, although it does not open until September, they already have confirmed concerts for all next year, Many of them with Sold Out.

The ‘in vitro’ fertilization has taken a surprising step using mitochondrial DNA

by

A child, three parents. It might seem science fiction, but it is already a reality. It is a reality that It started a decade agowith the approval in the United Kingdom of a novel technique that allowed Enter genetic information of a third person in a fertilization process In vitro Eight births. The British team to launch this technique has published the results Obtained from monitoring nine babies born after a fertilization process In vitro. A process with an important peculiarity: the introduction of mitochondrial DNA from a donor. Mitochondrial diseases. To understand the scope of the new procedure, we have to understand the reason that led to the development of this technique, avoid the transmission of mitochondrial DNA diseases. A problem that is estimated affects about 5,000 births per year. The mitochondria is a part of the cell responsible for producing energy but also has a DNA segment which is inherited matrilinearly. This matrilinear transmission can only be inherited by the mother, although they can affect people of any sex. This DNA can present harmful mutations that usually affect the proper functioning of this intracellular “energy” central “, which derives in diseases that manifest especially in those tissues that require the most energy, such as those of the heart or the brain. We do not have a cure for these diseases, but now we have a way to cut its transmission. Pronuclear transfer. The technique It is called pronuclear transfer And, according to the team that has launched it, it is done after the fertilization of the ovule, and consists in transplanting the nuclear genome of the ovule with the mutation to a new donor ovule, this with the desired mitochondrial DNA. The resulting cell has the parents’ nuclear DNA but the mitochondrial DNA of the donor parent. Studying the technique. The details of the study were described through two articles published in the magazine New England Journal of Medicine. The first of them He focused on studying the success of the technique itself. The technique did not eliminate the entire original mitochondrial DNA since in the core extraction process, part of this DNA was also captured and introduced into the new cell. According to the team, its presence in the neonate blood ranged between undetectable levels up to 16%. “The findings give rise to optimism. However, research to better understand the limitations of mitochondrial donation technologies will be essential to improve treatment results,” explained in a press release Mary Herbert, who led this part of the study. Healthy babies. He Second study He focused on clinical results, both on mothers and babies. During pregnancies only a complication was detected in one of them (hyperlipidemiaan excess of blood lipids), which responded to the prescribed treatment. The eight babies were born healthy and their development was normal during the study period, with most babies without health problems and the rest with mild problems that the team considers not related to the donation process. Regarding the success of the process, the team did not detect mitocondrial DNA in five of the eight babies, and the mutations that detected in the remaining three were maintained below 20%, which is far from the limit of 80% from which problems could begin to occur. The monitoring of these cases is still necessary to better know the evolution of each case. Ethical considerations. This monitoring will be necessary to clear doubts about the possible long -term impacts of this technique, a key consideration in the ethical discussion around the procedure. The United Kingdom approved this technique in 2015, but there are still many countries that have not legislated in this direction. “The study also raises ethical and scientific questions. The combination of nuclear and mitochondrial DNA of different people could have long -term effects still unknown,” indicated a Science Media Center (SMC) Rocío Núñez Calonge, scientific director of the International UR Group and coordinator of the Ethics Group of the Spanish Fertility Society. And in Spain? Spain would remain in a legal limbo, without clear legislation in this regard, experts explain. “In Spain, our (…) (Law) on assisted human reproduction techniques, does not explicitly refer to this technique (which did not exist when this legislation was approved) by what Sensu stricto The procedure would not be expressly prohibited or explicitly authorized in our country. Essentially it is not regulated. The legal and ethical doubts that subsist have prevented, so far, that the technique of the three parents is applied in Spain ”, explained to SMC Lluís Montoliu, researcher at the National Biotechnology Center (CNB-CSIC) and Ciberer -iscii.
