29 years ago we clone to the Dolly sheep. Thanks to this, today we are one step closer to solving the fertility crisis

Imagine a future in which the infertility caused by the lack of ovules or sperm is no longer an insurmountable obstacle. A future where two men can have a biological child together, or where A woman who has lost her ability to produce ovules For age or for a cancer treatment may have offspring with its own genetics. This future, which until now belonged to science fiction, is a little closer thanks to a revolutionary advance that has been published in Nature. Biology This advance, which seems like a science fiction, has been made by the team of researchers at Oregon Health & Science University, led by Dr. Shoukhrat Mitalipov. In this case they have managed to develop an experimental technique that forces a skin cell (somatic) to reduce your number of chromosomes in half. It is, in essence, the most crucial and complicated step in the creation of a gamete (an ovule or a sperm). A process they have called mitomeiosis. To be able to understand it, you have to know that all the cells of our body have in total 46 chromosomes in its nucleus. But there is an exception: sperm and gametes that They have 23 chromosomes. A very important number so that when an ovule and sperm merge, they have a total of 46 chromosomes. That is why it is revolutionary that they have managed to get a skin cell to have 23 chromosomes to be an ideal candidate to give offspring. The trick. The natural process to create these haploid cells (with 23 chromosomes) is called meiosis. A very complex type of cell division that has been investigating for a long time. This made it replicate in a laboratory, which is known as in vitro gametogenesis (IVG) was one of the greatest challenges of biology. Something that now reminds us of what we already saw with the Dolly sheep in the cloning process. OHSU’s team addressed the problem in an ingenious way. Using a technique similar to cloning, called nuclear somatic cell transfer (SCNT). A technique that is complex, but can be summarized in three different steps: The first thing is to take a donated human ovule and extract the genetic material. In this way, the ovule maintained all its cytoplasm with the organelles, which ultimately is like the machinery that the cell has to produce energy and carry out many processes such as meiosis. Once done, a skin cell is taken (a diploid cell with 46 chromosomes in a 2N state) and is extracted the nucleus inside. Now it only remains to introduce the core of the skin cell into the ovule that has been emptied. The result. In this case it was amazing, since the ovule cytoplasm could ‘deceive’ the skin’s core, forcing it prematurely into a state similar to the metaphase of the Meiosis. This caused its 46 chromosomes to be organized in a spindle ready to divide, despite having skipped the DNA duplication phase in the cell cycle that is before the division of the genetic material. The problem. However, here they met a wall. In nature, the entrance of the ‘active’ sperm to complete its division, being mediated by a large number of zinc. But in this case, when they tried to fertilize the SCNT ovules with sperm, the vast majority (almost 77%) remained ‘arrested’ without reacting. The natural signal was not enough for this artificial construction. The solution in this case went to develop an artificial ‘starter’ key. After sperm fertilization, they applied an assisted activation protocol an electrical pulse by electroporation to simulate the calcium entry caused by sperm to its entrance, followed by a treatment with a chemical inhibitor called Roscovitin. And it is something that ended up working. Forced activation made the modified ovules leave their arrest and complete the division. The 46 chromosomes of the cell were separated, leaving an average of 23 chromosomes within the fertilized ovum (now a zigoto) and expelling a small polar body from the rest, having achieved the long -awaited ploidy reduction that was the objective of this experiment. Progress. The embryos resulting from this experiment containing chromosomes of the skin and sperm cell, beginning to divide and even some reached the blastocyst phase (an early development of about 5-6 days), with a success rate of 8.8%. This shows that genomes can integrate and work together. It’s just a test. The authors who are still a long way forward, since for now it is a “proof of concept” by not being a perfect replica of natural meiosis. In this case, segregation is random unlike meiosis, where it is ensured that each daughter cell receives a copy of each of the 23 types of original chromosomes. In this project the separation of homologous chromosomes (the paternal and maternal) was completely random. This generates aneuploid embryos that are incompatible with life. In addition, it also lacks ‘cross -rise’ or crossovera vital mechanism in meiosis where paternal and maternal chromosomes exchange fragments creating genetic diversity. This is something that is not present in this process and that takes away a lot of variability. The future. Despite the limitations of this study, work is a fundamental milestone. It aligns with other laboratories such as the Japanese Katsuhiko Hayashi that in 2023 managed to create functional ovules From male mice skin cells, with which healthy offspring were born. In the long term, the implications of these studies give hope to those women who suffer from infertility due to lack of functional gametes and who want to have offspring with their own genetics. The same happens in same -sex couples that also open the door for a couple of men (using a skin cell to create an ovule) or women (creating sperm) can have biologically related son between both members of the couple. Although we cannot also forget that right now there is a fertility crisis that causes that in Spain, for example, there is reduced birth rate. This is also conditioned that it is … Read more

The eruption of a volcano was synonymous with danger 100 years ago. Today has made Iceland a theme park

Exactly one year ago, Iceland took a unexplored path In his fight against mass tourism: in essence, tell the truth to the visitor. Thus began a marked campaign For a slogan: “No one will save you if you fall”, which unequivocally came to confirm the hordes of the dangers of getting too close to an erupting volcano. Today, Iceland wonders if it was worth “opening” both the world. The awakening that changed everything. In 2010, when Eyjafjalajökull volcano interrupted air traffic European with an ash cloud that paralyzed the continent, Iceland went from being a remote island and evoked in Nordic sagas to become a global stage. The images of glaciers, black beaches and hot springs spread by international chains aroused the curiosity of the world in a country that had just suffered the blow of The financial crisis. With the campaign Inspired by Icelandthe government and tourism industry They took the moment. From then on, the landing of low -cost airlines and Viral phenomena In social networks (including a Justin Bieber video clip between waterfalls and aircraft remains) they catapulted the island to essential destination. Mass tourism. In just fifteen years, the number of visitors went from less than half a million to More than 2.3 million annuallymultiplying the local population several times during the high season. Tourism revitalized villages, generated employment and transformed the economyto the point of becoming the Main motor of the country. Locations Like Vikonce agricultural, they saw how the stables gave way to guest houses, improvised coffees in school bus and attractions of adventure. Immigration accompanied This boom: in some municipalities, foreigners are already a majority, and the arrival of new residents has even caused an unexpected “baby boom”. For many mayors and local businessmen, current problems are preferable to the decline of peoples that previously seemed condemned to abandonment. The identity dilemma. However, obviously not everything is good news. Tourism has contributed economic vitality, employment and infrastructure, but also tensions. Farmers complain about visitors who enter their lands or feed horses without permission, even causing deaths of animals. In Vikthe massive arrival of foreign workers has altered the social and urban fabric, with prefabricated homes that change traditional aesthetics. Even in schools they have had to Put posters to prevent tourists from photographing children. In the environmental plane, basic systems as the sewer They have been overwhelmed. Many Icelanders recognize the prosperity that tourism has given them, but they wonder how much local culture can resist without diluting. Iceland as theme park. More than a decade later that Eyjafjalajökull Cover the European sky with ashes and put the country on the global map, many critics argue that the island has run the risk of becoming in a “volcanoes theme park.” The geysers, glaciers and mountains of fire are today part of an itinerary Almost prefabricated, driven by low -cost airlines and Instagram selfies, which concentrates crowds in a handful of iconic landscapes while other regions remain outside. What was previously perceived as an indomitable and mysterious territory has become a tourist decoration subject to the logic of rapid consumption, where the eruption that attracted the world was transformed In advertising claim permanent. For many Icelandic, the paradox is evident: the volcano that saved the economy now threatens to devour the essence of their country. The future. Thus, academics and analysts propose Diversify the routes and offer deepest experiences linked to the history and culture of the country, to prevent tourism from reduced to a handful of “postcard places.” Regions such as Western Fjords or Fisheries North are still relatively on the sidelines, although the opening of direct flights could change the situation. The issue, according to many Icelanders, is not to close the door to visitors, but rethink the model: Attract those who want a longer and more conscious experience, instead of fast visits dictated by social networks. The national phrase Þetta Reddast (“Everything will work out”) reflects the resilient optimism of the country, although now faces the most uncomfortable question: Can Iceland continue to receive the entire world without sacrificing what made it unique?

70 years ago the United Kingdom took the most remote islet in the world to frustrate the USSR. Today is a huge headache

Rockall is a sharp stone in the middle of the Atlantic. Literally. Small, inhospitable, isolated, The islet It seems molded on purpose to repel any human presence. No one lives there and the few adventurers who have challenged the island, tried to spend as long as possible on their surface, have endured as much a month and a half. However and despite all that, Rockall stars in an exciting story that Even today It is marked by the controversy. After all, it has gone from being an important piece for the national defense of Great Britain (and the whole of NATO) to an important economic asset. In a (remote) place of the Atlantic … Throughout the Atlantic there are countless islands, archipelagos and rocks, but few are as inhospitable as Rockalla small rocky promontory of the North Atlantic. He arrives with reviewing a few data to get an idea of ​​to what extent he is isolated and is the last place on the planet in which one would want to spend his vacation. Rockall is among the coasts of Scotland, Ireland and Iceland, hundreds of kilometers from anywhere inhabited. To find houses and population you have to look at 370 kilometers From there, a NORT UISTin the Exterior hebrids (Scotland). “The most isolated rock”. It is not just that Rockall is far from everything. It is directly thought to repel the presence of humans. The islet measures only 25 meters wide and rises 17 m above sea level, which explains that its slope is often shaken by the waves of the Atlantic. There is no one to live there, but the few people who have tried to try their luck have encountered an inclined and rocky surface, a granite block in which there is hardly any space of 3.5 x 1.3 m level enough to stand. In the middle of the last century the British naturalist James Fisher described Rockall as “the little most isolated rock of the oceans of the world.” Even more graphic was a few years ago Lord Kennet, torque and exmarinero than He referred to the islet as the “most desolate, most despair and more horrible” place on the planet. The person who has spent more time on his sharp rocks was the surveyor Nick Hancock, who endured 45 days on its surface. A few years ago a teacher and veteran of the British army wanted ‘Solo’ a month. A rock with an intense story. Given its characteristics, one might think that Rockall is a rocky point without any interest in the middle of the North Atlantic, an islet away from political debate or territorial disputes. Not at all. Its history can go back several centuries agobut he became especially intense in the mid -XX. It was then, at the end of the summer of 1955, to be more precise, when Queen Elizabeth II authorized the annexation of the islet and ordered the British Royal Navy to “take possession of the island.” That same year, Remember the BBC chaina commander reported the successful “conquest” of Rockall. An indomitable island. That episode has already demonstrated how indomitable the rock islet is. The HMS Vidal, a recognition ship by the British Royal Navy, arrived in the area on September 15, 1955, but the sailors It took several days to be able to raise your flag. The reason: the very strong and violent wind gusts. The BBC Slide which was the last territory claimed by the British Empire. Years later, In 1972Parliament voted in favor of incorporating (already formally) Rockall into the United Kingdom, integrating it into the Western Islands of Scotland. But … why? 70 years ago Rockall was the same inhospitable, uninhabited and isolated rock that is today, so why the hell was Great Britain interested in his possession? What was lost there? To understand it you have to keep in mind the complicated geopolitical map of the 50s, In full cold warwhich conferred to Rockall a special value. With the NATO submarines and the USSR patrolling the North Atlantic, its possession became a festive issue. Not just that. Rockall may be isolated from everything, but less than 400 kilometers from there, in the exterior hebrids, London had its first Test field For American guided nuclear missiles. The islet may be hell on Earth, an sharp rock in which it was impossible to live more than a few weeks, but … what if “hostile agents”, as spies at the service of Kremlin, managed to settle in the area to monitor British tests? Beyond the Cold War. The USSR collapsed in the early 90s and London’s priorities in defense became others, but Rockall did not lose interest. Of course: this went from the military strategy to the field of economy and resource management. On the island the geologists identified a special type of granite, but if for something he stood out it was the potential of their marine bed and its waters. They interested their possible oil reserves. And interest (and much) the fishing richness that hid their waters, where rappes are captured, North Gallo, haddock or squid, among other species of high value. The problem is that this wealth not only interested London. He also did Islandia or Ireland. A headache. In 1982 the United Nations Convention on the Law of the Sea (Convent) established that rocks without population or economic fabric, as was the case of Rockall, could not be used as a basis for territorial claims. In other words, the islet could no longer be used as ‘key’ to argue the theoretical legitimacy of the United Kingdom over the surrounding waters. However, a Google search arrives to verify that in recent years law and fishing in the area have been a reason for friction With Ireland, Iceland or even Denmarkas representative of the Faroe Islands. The ‘Roces’ of 2019. One of the most tense episodes was lived before the pandemic, in 2019, when Scotland warned the Irish ships on the “illegal” drag fishing that … Read more

60 years ago Singapore lived an alarming housing crisis. Today almost all of its inhabitants have their own home

Singapore is a constrained nation, rich and with one Huge concentration of population, ingredients that a priori invite you to think about a complicated residential market. His most iconic image is in fact that of a ‘skyline’ drawn by huge and brand new skyscraper. However, despite the fact that it has not been oblivious to market reheatingthe city-state presents a curious peculiarity: a overwhelming majority of its population resides in homes promoted by the State and the country has one of the biggest Property rates of the world. His model has fascinates experts for years. A unique country. It is not that the real estate market of Singapore is special, is that it is the nation itself. If it had to be defined with three adjectives, they would be small, concentrated and prosperous. The city-state is barely 720 km2 And he welcomes just over six million people, so that his population density is around 8,200 people/square kilometer. These data make the island nation one of The most concentrated of the planet, behind Macao and Monaco. If we talk about per capita income, an indicator of population wealth, Singapore also sneaks into the top of international rankings. In fact, he heads Asia’s list and stands out on the world map. According to The data which manages the US administration, at least last year there were only two nations that exceed it (both small): Monaco and Liechtenstein. The city-state also stands out for Your concentration of millionaires. Singapore’s paradox. If the country’s economic and demographic data are curious those of its real estate market are no less. Especially because, as he pointed out In March Wei Low In an analysis published in Bloomberg, the city-state presents a “paradox.” Singapore is not cheap for real estate professionals, but at the same time it is surprisingly affordable for its inhabitants, which seem to have no problems when acquiring a house. Does not lead the List of countries With a higher housing property rate, but it is appearing in the upper part of the table, with a percentage much higher than that of Spain. Here the Bank of Spain (BE) Calculate that the percentage of households owned by their main house The European average It was slightly lower, of 69.7%, a percentage that brings together, however realities so disparate such as Romania (96.1%) or Denmark (59.3%). First percentage: 90%. In the case of Singapore the analysts They usually point that the property rate is around 90%. That The reference that is handled from Wei or the one that collects the Trading Economics platform, which Precise that the average property rate in the city-stated between 1980 and 2024 was 89.2%. The last indicator (of 2023) would be 90.8%, a few points below the maximum of 93.1% scored at the beginning of the century. Such a percentage has made often analysts are done a question: How have Singapore managed to reach a rate of ownership of the housing so surprisingly high? Second percentage: 80%. The above is much better understood when knowing Another indicatorequally striking: it is calculated that More than 80% of the population of the country resides in apartments built by the State, which also controls an overwhelming part of the territory. In 2018 Abhas JHA, Urban Development Manager and Risk Management of the World Bank, I calculated that 90% of the land were owned by the administration, almost double that in the 60s. During the same period, between the 7th and the present, the property rate He also shot. Three letters: HDB. To understand these percentages, we must know the recent history of Singapore and especially the origins of one of its fundamental organisms at real estate, HDB, the acronym in English of Housing and Development Board. In the late 50s, when the city-state reached its self -governmentthe Singaporenses authorities met A challenge Capital: its housing park had not grown alongside that the population of Chinese, bad and Indian immigrants, which translated into overcrowding and illegal populations. To solve that pressing “Residential Crisis” In 1960, HDB was created, an organism that was launched with a strong support of the government. In three years he had built 21,000 homes, a couple of years later the figure amounted to 54,000 and after a decade it resulted in the crisis. The result, highlights the organism itself On its websiteIt is that today “about 80% of the population of Singapore resides in HDB homes in 24 cities and three urbanizations.” As a reference, at the beginning of the 1960s only a small part of the Singapurenses (about 9%) resided in houses of public origin. Government graph explaining the sales system to 99 years. One date: 1964. In the residential chronicle of Singapore there is, however, another even more important date, such as remember Bloomberg Agency: 1964. That year the administration decided to offer subsidiary apartments for sale as part of the program ‘Housing access plan for the people’an initiative aimed at medium-low-income families who wish to acquire their own home. Since then the country has continued to polish the system, creating a mechanism that has favors for more than 30 years the mixture of ethnic groups (Chinese, Malays or Indians) to prevent them from forming in the small city “Racial enclaves” and a program that encourages the modernization and reform of the housing park. “Being a home owned citizens a tangible asset and a participation in the construction of the nation. There are more than one million HDB houses, in which 80% of the resident households reside. Of them, nine out of ten are owners of their homes,” stands out The Singapore government. How does the system work? There is an important detail. As remember Administration, The majority From HDB homes are sold with a 99 -year -old lease contract, a formula that, Reason the Government“satisfies the needs of the owners and their children while guaranteeing the rehabilitation of land and building construction.” The formula is not exclusive to the city.

For years the Airbus A380 symbolized European power against Boeing. Today it survives as a colossus without the kingdom

The Airbus A380 was born as a huge dream, almost a declaration of intentions of the European industry in front of the Boeing’s historical domain. It was the passenger plane bigger in the worldwith two full plants, space for bars and suites, and a silence in cabin that turned the flight hours into a different experience. For Airbus, the program was not just a commercial project: it was the tangible proof that Europe could look in front of the United States in the field of civil aviation, raising a colossus capable of marking a before and after in the heavens. For a while he got it. Each A380 landing turned an airport platform into a show. Thousands of curious people came to see that mole of 73 meters long and 24 meters higha building with wings that imposed only with its shadow. It was a continental pride, an engineering triumph and a symbol of what could be achieved when several countries align resources, knowledge and ambition. However, that same pride soon began to live with an uncomfortable question: how is it possible that a plane that seemed perfect has had such a short tour? The dream of the global hub and the change of the market direction When Airbus conceived the A380, he did it under a clear premise: the future of aviation would go through increasingly saturated Megahubs. His strategy bet on a “Hub-And-Spoke” model in which passengers would come together in large airports and then distribute on connection flights. The A380 was the key piece of that puzzle: a gigantic plane capable of reducing congestion by transporting more than 500 people at once. In theory, the business was solid. Airbus estimated that more than one thousand units of very large capacity aircraft would be sold in the following two decades. But reality was very different: The market was fragmented towards more frequencies and smaller airplanesweakening at the root the argument that justified the European giant. At the same time, the technical revolution changed the rules of the game. The advance of long -range bimoretores, with increasingly wide ethops certificationsallowed to fly virtually any intercontinental route with only two engines. The Boeing 777 and, later, the 787 and he demonstrated that the same autonomy could be offered as a four -way, but with less consumption, less maintenance and greater operational flexibility. That remained attractive to an airplane that, although efficient per seat in high occupation conditions, depended on filling hundreds of places to be really profitable. In a market that preferred more daily flights with smaller airplanes, the A380 began to run out of hole. The infrastructure also played against. The A380 was classified as aircraft F code (65-80 m of wingspan)which forced many airports to invest in specific positions, double catwalks and adapted filming streets. The compatibility manuals of A380 itself They detail those demands. For Hubs like Heathrow or Dubai, those investments made sense; For the rest, they were a difficult expense to justify. Even in prepared airports, rotation times were more complex than with other airplanes, and that remained efficiency against models that could operate with less conditions. Thus, the one who should be the undisputed king of the skies ended up being an exclusive guest in a few airports on the planet. The operational economy did not help either. With occupancy rates close to 100%, the A380 offered a cost per competitive seatbut when the demand went down the model became a heavy load. In addition, its load capacity in the cellar was not as flexible as that of rivals as the 777-300er or the A350-1000, which combined better passengers and goods. In practice, the A380 was a technical prodigy but too sensitive to occupation factor already variables that escaped the control of the airlines. Despite these difficulties, the program resisted thanks to a main client: Emirates. The Gulf airline turned the A380 into its flagship and accumulated more than a hundred units. But that dependency was lethal. In 2019, Emirates drastically reduced his A380 request To bet on A350 and the A330neo. Airbus officially assumed it With a overwhelming statement: without that support there was not enough request for request to keep production alive. The decision was irreversible: on February 14, 2019, the end of the program was announced, and In 2021 the last unit was delivered. The two -storey giant had come to an end with just 251 copies manufacturedfar from the initial forecasts. The outcome left an obvious paradox. The passengers worshiped the A380, their flight experience was unsurpassed and their presence generated expectation where it flew. But the airlines, in general, did not want it in their balances. The liquidity problems in the second -hand market confirmed it: The first A380 returned by Singapore Airlines ended up scrapped for piecesa curious outcome for such a young plane. The outbreak of the pandemic in 2020 seemed to seal the fate of the A380. The majority of airlines sent it to prolonged storage, and some even They announced their final withdrawal. However, the recovery of international demand and delays in the deliveries of new wide fuselage aircraft, such as the Boeing 777xThey changed the script. Emirates invested billions in reconditioning its fleet With new cabins, Lufthansa recovered some units and Qantas, Singapore or Etihad They also reactivated part of their planes. The A380 thus found a second life, although much more limited: it is still useful in high demand routes and in airports with slots problems, but its long -term future remains marginal. The A380 is not the only one to live this transition. The Boeing 747, which for decades was the real “Jumbo Jet”, closed its production line. The difference is that 747 has found a stronger niche in the cargo market, thanks to The Morro Gate of 747-8F and its volume capacity. In passengers, a few units are barely survived in the hands of Lufthansa and Korean Air, but their time also seems told. The relay is already underway: the … Read more

Our conversations with Claude were untouchable. Today the urgency of data presses to make them raw materials of the AI

We usually talk to artificial intelligence as if I were one more person and sometimes we trust very personal information. However, we rarely stop to think about what happens to those conversations. Until now, the standard in good part of the sector had been to use them to train models, unless the user opposed. Anthropic represented an exception: Claude He had an explicit policy not to use the conversations of his private clients for this purpose. That exception has just broken. The reason is direct and forceful: the data is the raw material of the AI. Anthropic has just announced in his official blog An update of its service conditions for consumers and their privacy policy. The users of the Free, Pro and Max plans, including the sessions in Claude Code, must explicitly accept or reject that their conversations are used for the training of future models. The company set the deadline until September 28, 2025 and warned that, after that date, it will be necessary to choose the preference to continue using Claude. The Anthropic turn. The modification does not affect everyone equally: services subject to commercial terms are left out, such as Claude for Work, Claude Gov, Claude for Education, or access by API through third parties such as Amazon Bedrock or VerTex Ai from Google Cloud. Anthropic states that the new configuration will only apply to chats and code sessions initiated or retaken after accepting the conditions, and that old conversations without additional activity will not be used to train models. It is a relevant operational distinction: change acts on future activity. Why this change? Anthropic points out that all language models “train using large amounts of data” and that real interactions offer valuable signals to improve capacities such as reasoning or code correction. At the same time, several specialists have been pointing to a structural problem: The open web is running out as a fresh and easily accessible source of informationso that companies look for new data paths to sustain the continuous improvement of the models. In that context, user conversations acquire strategic value. Although Anthropic emphasizes security (improving Claude and reinforcing safeguards against harmful uses, such as scams and abuses), the decision probably also responds to competition: OpenAi and Google remain references in the field and require large volumes of interaction to advance. Without enough data, the distances in the AI ​​race that we are witnessing live can increase. Five years instead of thirty days. Next to the training permit, Anthropic has expanded the retention period for shared data for improvement purposes: five years if the user agrees to participatecompared to 30 days that govern if that option is not activated. The company also specifies that the eliminated chats will not be included in future training and that the feedback Envoy can also be kept. It also states that it combines automated processes and tools to filter or obfuscate sensitive information that does not sell user data to third parties.
