This strategic and tiny island has been disputed for 200 years. And the US and Canada still are not clear to whom it belongs to

by

The recent one Donald Trump’s insistence on Annexar Canada as the 51st state He has given for reflections in the American political sphere. While the idea does not seem taken seriously in Washington and the Canadian government has made it clear that it has no interest in joining the United States, The New York Times performed an electoral code analysis of such a scenario revealing an unexpected consequence: the incorporation of Canada would guarantee a political advantage for the Democratic Party in future elections. Be that as it may, the only certain thing in this whole story is the eternal dispute over an islet between both nations. An island and its importance. WE TALK ABOUT MACHIAS SEAL ISLANDa small islet of 18 hectares located at the point of confluence between the Bay of Fundy and the Gulf of Maine, which represents the last territorial dispute between Canada and the United States. Although its rock size and geography are little or rather liable, its strategic value and the wealth of its waters They have maintained the latent conflict for more than two centuries. A lighthouse as a symbol of sovereignty. The history of the dispute goes back to the war of 1812when both the United States and Great Britain claimed the island and its surrounding waters due to their location on an important navigation route. In 1832, Great Britain built a lighthouse on the island To consolidate its control, and since then, Canada has maintained a permanent presence in the place through Farros that, in addition to its maritime signaling work, act as symbolic guardians of Canadian sovereignty. In this regard, Russell and Anthony Ross, Farros brothers, turn every 28 days to keep the lighthouse in operation. Isolated on the island, their work goes beyond surveillance: they receive visitors who arrive in summer and, in winter, they support the extreme climate of the Atlantic without the possibility of returning to the continent until its allocation ends. For them, the island is more than a territory in dispute: it is their temporary home and a symbol of a tradition that few still keep alive. Frailecillos on the island A sanctuary for wildlife. Despite its uncertain geopolitical status, Machias Seal Island is recognized as a sanctuary of sea birds. The reason? Thousands of Atlantic Frailecillos, Common Mergles, Arctic Charranes and Common Alcas nest there every summer, making it a reference point for scientists and bird observers. In fact, the Canadian Wild Life Service protects access to the island, allowing only the arrival of two daily tourist boats, One from Maine and Another from New Brunswickwith a limited quota of visitors. Scientists like Tony Diamonddirector of Atlantic Laboratory for Avian Research, have studied these colonies since 1995, highlighting the importance of the island’s ecosystem as a thermometer of the state of the ocean. Tourism under surveillance. To avoid major evils, the experience of tourists is rigorously controlled. So much so, that to avoid damage to nests, They must remain in wood cattleway and use small observation structures camouflaged in the landscape. Although getting to the island is not easy, most of Visitors consider the effort to be worth itsince it is one of the few places where you can see these frailecillos in their natural environment without disturbances. The dispute: Waters of the gray zone. Beyond the small islet, the true conflict between Canada and the United States is not on earth, but rather in the sea. The waters around Machias Seal Island They are known as the “Gray Zone”an area of ​​approximately 700 square kilometers where both countries claim fishing rights. Moreover, in the last decades, The growing lobster demand has turned the area into a crucial economic resource. The price of crustacean has tripled, reaching values ​​of up to 4 Canadian dollars for 400 grams, which has promoted the prosperity of fishing communities Like Grand Manan, in Canada. Live in the conflict. For many fishermen, The gray zone represents a constant income opportunityand although there are no formal agreements, they have developed a coexistence system based on mutual respect. Of course, not everything is harmony. As the lobster demand has continued to increase, The pressure on marine resources is increasing. Sector veterans warn that The overfishing could exhaust the lobster populationfollowing the same collapse pattern that affected the herring industry, background fish and scallops in the past. Uncertain future. Be that as it may, and despite the territorial dispute, so far Canada and the United States have avoided an open conflict about Machias Seal Island and the gray areamaintaining that fragile balance between the symbolic presence of Canada on the island and the joint fishing exploitation in its waters. Yet, The recent political and commercial tensions between the two countries They have generated uncertainty about the future of this enclave. In that sense, Trump’s latest statements have not helped. The inhabitants of the island, whether beareros, scientists or fishermen, continue with their lives at the same time that international policy follows its course. While the frailecillos continue to nest in the cliffs and lobster ships they slaughter in the gray area, the islet is maintained as a tiny point on the map, although not any one: one with a geopolitical, economic and ecological influence much larger than its size suggests. .Imagen | Melissa McMasters, Melissa McMasters In Xataka | The longest dispute is a 500 -year -old mystery.

We have been growing lettuce in space for years. Now we have discovered that they are more likely to get sick

by

Bad news for astronauts who usually eat healthy. That is, for all astronauts. The crew members ago of the International Space Station consume the vegetables that they themselves cultivate in microgravity: lettuce, peppers, radishes. Some spicy Chile. More recently, vegetables have joined the autoconsumo astronauts of the Chinese Space Stationwhich already has lettuce, cherry tomatoes and chivesalthough it does not carry so much in orbit. The problem is that space salads They are not as safe for consumption as we thought. A team of researchers from the University of Delaware has discovered that lettuce and others Microgravity cultivated vegetables They are more Pollution prone by bacteria such as Salmonella. The study, funded by NASA, shows that under conditions of microgravity, plants tend to open their stomata (the small pores of their leaves and stems) instead of closing them to prevent the invasion of pathogens. To reach this conclusion, the team created a simulated microgravity atmosphere in the laboratory with a device called clinostat, which rotates plants as a chicken in an grill. The results showed that, under these conditions, the salmonella more easily infects the tissue of the leaves. Friendly bacteria also lose their protective effect The researchers explored the use of a friendly bacterium, B. Subtilis, as a solution to the problem. However, bacteria, which on earth helps plants fight pathogens, He failed to protect them in it Simulated microgravity environmentwhich suggests that space changes significantly the interaction between plants and microbes. The finding is important. Not only because he doubts that the salads of the International Space Station are totally safe, but also because it helps to understand the challenges of agriculture in future space colonies. With population growth on earth and the loss of agricultural land, space is an increasingly realistic option for food cultivation. But if they want Avoid an outbreak of salmonellosisthe future farmers of space be worth the future farmers to wash their hands well with soap and water.

Spain lives a brutal birth crisis. And that is causing mothers above 40 years to grow more than ever

by

In Spain they are born every time Less children. And increasingly. The balance That the INE has just published with the first global photography of birth and mortality in Spain throughout 2024 leaves some surprises but above all confirm the trends that have been marking the demography of the country for years. And one of the clearest is the gradual delay of motherhood: more and more women have children turned 40 or even with 50. And there is a fact that clearly reflects it: 10.4%. A (small) joy. They are still provisional data, so the photo that leaves The last report of the INE could vary over the coming months. However, waiting for the definitive balance, Spain seems to have closed 2024 with a (small) demographic joy. His birthday has rebounded. In a shy and that has not served to compensate for the number of deaths and thus avoid a vegetative balance in Red numbersbut at least allows you to cut the negative trend of the last decade. A percentage: 0.4%. That is the birth increase registered by the INE in 2024: 0.4%which translates into 1,378 births rather than in 2023. Throughout the last year they came to the world in Spain 322,034 babies, almost 1,400 more than during the previous 12 months. The data leaves a positive reading and another that is not so much, depending on how much we amounts to the temporal focus when analyzing it. The first is that it represents the first birth rise since 2014, when the balance touched the 427,600 babies. However, despite that climb, the Spanish demographic engine does not have today Nothing to do With the years of the Baby Boomthere for 50, 60 and mid -70s, when they were born in the country between 650,000 and 660,000 babies a year. The INE reflects for example that in 1975 they were noted almost 669,400so since then the collapse has been 52%. And a figure: 33,570. The balance of the INE helps to understand another of the key factors of Spanish demography: maternity. And when analyzing one of Trends clearer is its progressive delay. More and more Spanish have children with 40 or more years, to the point that in 2024 that profile was behind 33,570 births. What does that mean? That one out of ten Babies born in Spain (10.4%) already do it from women who exceed thirty. In 2014 that percentage was significantly lower, of 7.2%. Year Births of women 40 or more years Middle Ages to Maternity 2000 10,163 30.72 2004 15.017 30.87 2008 22,026 30.83 2012 28,289 31.56 2016 34,452 32.0 2020 34,858 32.3 2024 33,570 32.6 (data of 2023) Looking back. In 2014 the INE scored 30,946 births of women of 40 or more years, so that the increase has been 8.5% in a decade. During the same period the number of babies born of mothers under 25 years fell 21.9% and the births of women between 25 and 39, the one with the greatest weight, retreated 27.9%. If you look further back the trend is even clearer. In 2000 the INE counted in Spain 397,632 birthsof which 10,163 were related to women who had already arrived or exceeded quarantine. That is, at that time its weight was only 2.5% of the total and the number of lighting has shot 230% since then. In 2004, women of 40 or more years starred 15,017 birthswith what your number has doubled. The other indicator: Middle Ages. There is another clue that helps to understand how they are quickly changing motherhood in Spain: its Middle Agesan indicator that has practically not stopped growing over the last decades. If in 1976 it was located in 28.51in 2000 it was already 30.72, in 2010 it climbed at 31.2 and in 2023 it was 32.6 years. That is, the average has increased more than four years since the 70s. In the EU, a gradual increase of the age at which women have their first offspring. What are the causes? The big question. The increase in what the INE calls “Middle Ages to Maternity” And the number of women who give birth to the 40 years coincides with other phenomena that directly affect women, as the Professor of Human Geography Rafael Puyol recently pointed out in An article dedicated to the Spanish demographic crisis. The expert specified in particular the educational revolution and the incorporation and women into the labor market, in addition to cultural changes and the family model.

Some microbiologists have taken 10 years to solve a problem. The AI ​​has solved it in two days

by

Professor José R. Penadés and his Imperial College team in London had been working on a way of demonstrating how certain superbacteria are immune to antibiotics. After all that time they had finally achieved a conclusion in this regard. They recently dedicated to give AI a chance to solve the same problem. They got a surprise. Ten years they, 48 hours the AI. The scientists used a new Google AI tool called co-scientist to provide a brief prompt asking him about the essential problem they had been investigating for ten years. The AI ​​reached the same conclusion as them, but it took only 48 hours to reach it. And the AI ​​did not know the response in advance. One of the important details here is that AI could not have found out the solution looking for it on the Internet. Penadés and her team had not published the study, so Co-Scientist could not find the answer because it was not public domain. “I need to digest it”. The Penadés Professor He indicated in BBC How he learned that AI had reached the same conclusion in just two days. “I was shopping with someone, and I said,” Please leave me only one hour, I need to digest this. ” no. I could have saved years. Even considering the AI ​​solution as a hypothesis when they started working on the problem, having it would have saved years of work, Penadés explained. But it was the AI ​​went further. In fact, Google tool had done more than replicating its research. “It was not only that the hypothesis he provided was correct. He provided another four, and all of them made sense. And in one of the cases, he never occurred to us, and now we are working on it.” A for superbacteria. The study tried to reveal how some superbacteria are created that are resistant to antibiotics. The hypothesis proposed that superbacterial can form a tail from different viruses, and that allows them to spread between species. It is as if they had the “keys” to move from one place to another and “enter” different guests. That is the same hypothesis that Co-Scientist arrived in 48 hours. “This will change science”. For the Penadés professor “this will change science, sure.” Tools like this, says, “give the opportunity to play a great game. I feel as if I was finally playing a Champions League match with this.” And there I don’t know the thing: Evo 2 arrives. This discovery binds to launch these days of Evo 2the most large biology -oriented model so far. A group of researchers from the universities of Berkeley, Stanford, the ARC Institute, the UCSF and NVIDIA have trained an AI model with 9.3 billion nucleotides (from which DNA chains are created) from 128,000 Complete genomes. Thanks to this model it is possible to precisely predict all types of genetic mutations. Image | Wikimedia In Xataka | Some engineers have simulated 500 million years of evolution with an AI.

Reviewing data almost 30 years ago, scientists believe they have identified a new ocean in one of Jupiter’s moons

by

On September 21, 2003 the Galileo probe He was immolated in Jupiter’s dense atmosphere, the planet he had been investigating for almost a decade. 30 years after the arrival of the probe to the Jovian orbit and more than 20 years after the end of its mission, the NASA probe continues to offer us new information thanks to the old data that it sent us in its day. A new oceanic world. The study in question has indicated that Calisto is “most likely” an ocean world, a rocky body covered by a layer of water at least in a liquid. The key to the new study has been in a more exhaustive use of the data provided by the Galileo mission, including all its magnetic measurements. Callisto Callisto It is the satellite farther from your planet of Among the so -called four Galilean moons of Jupiter. It is also the second largest moon of Jupiter, with a simular size to that of mercury but with a remarkably smaller mass. One of the most striking details is its surface full of craters which gives Callisto an appearance “similar to a golf ball” The suspicion that this satellite hid an ocean inside It is not newbut the intensity of his ionosphere had been a limit to our ability to study the interior of the Jovian moon from a distance. The reason is that researchers They believed That the satellite ionosphere, an electrically and located conductive region located in the highest layers of Calisto’s atmosphere, could be “imitating” the magnetic footprint that would emit a hypothetical salt and conductive water ocean. That is, astronomers could not know if the magnetism detected proceeded from outside or inside the moon. A new look. New data and analysis tools have allowed to solve this issue. The team responsible for the new study incorporated the set of measurements Magnetic available from the eight occasions in which the Galileo probe survived Callisto. Combining methods. The team combined the analysis of the data obtained by Galileo with a model that simulated Calisto’s ionosphere. They compared the results of the observations with what the suggested in the theoretical model. From the results obtained, the team responsible for the study concludes that the satellite ionosphere cannot by itself explain the magnetism detected, but that the existence of a salt water ocean under the surface of the moon could contribute to the observations. The results therefore suggest the existence of such an ocean. The details of the analysis and its results have been published In an article In the magazine AG ADVANCES. The oceanic worlds of our solar system. Calisto is just one more in The list of candidates To oceanic worlds in our solar system, a list that includes different bodies in which we believe, with greater or lesser degree of certainty, that there are oceans. This list includes other moons such as Europe, Ganymedes, Lord it, Triton, and also a dwarf planet: Pluto. These planets are of great interest to astrobiology since they are the main candidates to house life or the appropriate conditions for the emergence of this in our space neighborhood. That is why a whole new generation of probes is focused on The study of this type of environments. The list includes NASA’s Europe Clipper Mission, and Juice (JUPITER ICY MOONS EXPLORER) of the European Space Agency. The first will be focused on analyzing in depth the moon Europe while the European mission will travel to several of these frozen worlds to collect information about what their layers of ice hide. To these missions, China Tianwen-4 could be added, whose observations could also give us important data about Calisto and his hidden ocean.

Exorbiting the International Space Station in two years

by

The International Space Station is, as the name implies, an international project. One of the most important and monumental international projects in history, the result of the collaboration of multiple countries. Now an entrepreneur wants to accelerate his end. In an ideal world, entrepreneurs could not undo what several countries have built. Much less if the reason is accelerate the conquest of Marsfor which the new rocket of said entrepreneur will be needed. But this is not any businessman. He is the richest in the world and has enough political power and influence to take us seriously. Elon Musk’s last idea. “It’s time to start preparations for exorbiting the international space station,” Elon Musk wrote in his X profile during Thursday afternoon. “It has fulfilled its purpose. Its incremental utility is very small. Let’s go to Mars.” When exactly? “The decision depends on the president, but my recommendation is to be done as soon as possible,” The businessman said. “I recommend doing it in two years.” That is, in 2027, two years before the date agreed by the ISS partners. An accelerated ending. At 25, the International Space Station shows signs of aging. Investments in maintenance have been increasing. Structural fatigue begins to be a concern. The risk of impact with space garbage does not stop growing. The plan agreed by the ISS partners was to keep the operating station until 2030 and then tow it with a special ship to a safe place (presumably the Pacific Ocean) for its atmospheric reentry. NASA asked Spacex to develop this vehicle by 2030. By then, hopefully, there will be Commercial Space Stations In the low terrestrial orbit. But by 2027, the year proposed by Musk, the continuous presence of Americans in space would probably be interrupted. The space would continue inhabited, yes, By Chinese astronauts. Can Trump retire the ISS a long time? That is the big question. The International Space Station involves five space agencies: NASA (United States), Roscosmos (Russia), the European Space Agency (Europe), Jaxa (Japan) and CSA (Canada). Canada operates the Canadarm robotic arm, Europe the robotic arm was and the Columbus laboratory … but in broad strokes, the ISS consists of two main segments that are from the United States and Russia. In the same way that Russia was threatening to decoup down her and leave before 2030, Donald Trump could propose the same. It is hard to imagine a scenario in which the European, Japanese and Canadian partners of NASA agreed with this abrupt ending. What would happen, for example, with European astronauts who were going to fly to ISS before 2030, Like the Spanish Pablo Álvarez? But it is not impossible to occur. “You are delayed.” Musk’s statements, yes, could have been hot written. He published them just a few hours after exploding against the former commander of the International Space Station Andreas Mogensenwho had called him a liar for statements in Fox News. Musk and Trump have been circulating the narrative that Astronauts Butch Wilmore and Suni Williams were abandoned by former president Biden in space after the Fiasco of the Boeing Starliner ship. Actually, NASA ordered a return plan for both during the Biden administration: to reserve two empty seats on the CREW-9 mission, which will return to Earth at the end of March (an exclusive ship for them would have cost dozens of millions). When Mogensen pointed out this in his X profile, Musk replied: “You are a complete mental retardation. Spacex could have brought them back several months ago. I offered this directly to the Biden administration and refused. His return was delayed for political reasons. Stupid.” Image | Elon Musk, Nasa In Xataka | It is not that Elon Musk has managed to introduce its influence on NASA. Is that he has entered sweeping

Three years after the beginning of the war, Europe wants to enter. The problem is that there is only one prepared nation: Ukraine

by

Europe has decades without a direct armed conflict in its territory, with the exception of Yugoslavia wars in the 90sthe last great episode of violence in European soil. Since then, security in the continent has been marked by A strategy based on deterrence and diplomacymore than in military confrontation. And, suddenly, the conflict in Ukraine recalled that fireworks It is not the same as direct fire. Europe before Ukraine. As we said, the European armed forces have been reserve for a long time. In fact and how we will see, mostly they have been reduced and adapted to a context of stability, with investments limited in defense and a focus on Peace maintenance and humanitarian assistance operationssuch as missions in Balkans, Africa or the Middle East. Despite the growth of NATO and its presence in Eastern Europe, European armies have been more accustomed to acting in controlled scenarios that to prepare a direct confrontation against a weight opponent such as Russia. Fireworks. In fact, this approach has led to many military operations from European countries being Mainly exercises, joint maneuvers and drills in allied countries such as Slovakia, Poland or Latviabut without the real experience of a conventional combat against a military power. And it is not the same to deploy troops for an exercise in the Baltic countries to face in battle against a force like the Russian army. Enter the war. Under all this context we arrive at this week. A few days ago several European leaders have gathered in Paris to discuss the possibility of sending troops to Ukraine as part of A possible peace agreementalthough the viability of this measure depends largely on the support of the United States. In fact, the summit was promoted by the decision of the Trump administration of exclude Europe from negotiations They started in Saudi Arabia between Washington and Moscow, although Trump has suggested that Europeans could perform “a peace maintenance role.” Plans and divisions. And then Europe seems to have realized that the “defense” had it careless. According to The Washington Postsome European countries consider The deployment of up to 30,000 soldiersthat, yes, they would not be on the front line, but as a deterrence in case of a resumption of the conflict. Another option, or plan B, is the one that They have called “resettlement force” destined to protect Ukraine from future Russian attacks in case a peace agreement negotiated by the United States is reached. That said, France is the country with the most advanced plans estimating that could contribute almost 10,000 soldierswhile the United Kingdom, through its prime minister Keir Starmer, has opened The possibility of a British contribution. And so far, because the rest of the countries have shown a more ambiguous position. Sweden and the Netherlands, for example, They do not rule out the shipment of troopsbut they have not made a specific decision. Germany, Poland and Spain have rejected the idea, At least for now. Foreign Minister Olaf Scholz emphasized that Any solution should be based on a strong Ukrainian forcewhile Donald Tusk, Prime Minister of Poland, said that Warsaw “does not contemplate sending Poles soldiers to Ukraine.” For its part, the Spanish government was blunt when pointing out that Peace is still far and only depends on Putinmaking it clear that any military mission should define objective, participants, mandate and leadership. Strategic objectives. If the “plan B” is given, with a peace agreement underway, the main mission of this eventual “resettlement force” would be guarantee the safety of Ukrainian airspaceallowing the reopening of commercial flights, and protect maritime trade in the Black Sea, fundamental for grain exports and other essential goods for the Ukrainian economy. It would also be prioritized The protection of key infrastructure such as Public Plant and Public Servicesthat have been constant target of Russian bombing since the beginning of the war. Ukraine proposes a broader approach. Meanwhile, Ukrainian President Volodimir Zelensky stated that Ukraine’s security does not necessarily require foreign troops in his territory. Proposed The creation of “Armed Forces of Europe”capable of responding on land, sea, air and artificial intelligence before any Russian aggression. He also stressed that advanced air defense systems would be effective measures to strengthen security without requiring permanent foreign troops. The elephant in the room. No doubt, Europe’s plan faces important diplomatic obstacles, the first of all: United States support It is, at the moment, uncertain. Although the Trump administration has insisted that European troops must guarantee the security of a future peace agreement, Defense Secretary Pete Hegseth made it clear that They must be part of a mission not related to NATO and not be protected by article 5 of mutual defense. Not just that. Even in the uncertain scenario of a peace agreement, the mission and role of Europe would require an American “backstop”that is, a support from the United States in case of a military escalation. Although there are no specific details, this support is expected It focuses on aerial power with operations based on Poland and Romania. In this regard, Starmer and Macron will travel to Washington next week To press Trump and ensure that the United States provides this strategic support. “Old” defenses. In the background, what is showing is a great weakness in its defenses, possibly oxidized. In fact, the Prime Minister of Denmark, Mette Frederiksen, warned this week at the Munich Security Conference that Ukraine is making weapons faster and less cost than any other country in Europe. It is not a trivial detail. It does so despite being at war, which shows the slowness of the continent in strengthening its military capacity. Frederiksen urged to reduce bureaucracy and increase arms production in collaboration with the United States emphasizing that Europe can no longer act as if it were in peacetime. The rise of the Ukrainian military industry. From the Russian invasion in 2022, Ukraine has exponentially increased its armament productionmanufacturing missiles, obuses and large -scale drones.

For five years we have tried to decipher a television signal that came from the sky. The mystery has been resolved

by

The news for the year in the cosmos has a name and surname: 2024 YR4, that asteroid whose probabilities of impact on Earth do nothing but up. But thousands of kilometers from our planet continue to happen fascinating events. Without going very far, X -ray telescopes have just revealed A superstructure of more than one billion light years. There are more, because for five years astronomers had been looking for a response to a television signal that came from space. The enigma has just been resolved. The mystery of the signals. For five years, astronomers who analyzed the data of the Murchison Widefield Array radio in Western Australia found an unexpected enigma: A television signal from heaven. Since the telescope is located in A radioelectric silence zone Designated to avoid human interference in radioastronomy, the detection of said signal was particularly disconcerting for the community. Even more strange was the fact that the signal It seemed to move through the skywhich led to all kinds of speculation about possible reflections of our own transmissions until, of course, theories about extraterrestrial activity. The answer, as almost always, It was something simpler. The discovery: airplanes. Apparently, the turning point came when Jonathan Poly, physicist at Brown University and leader of the United States research team, He had a revelation: “We said: ‘I bet the signal is being reflected in a plane’”. While this hypothesis had already raised before, no one had confirmed it with certainty. To check it, the equipment used advanced signal processing techniques, as close field corrections and beam formationwith which they managed to better focus close sources of interference. What happened? That the analysis revealed that The reflected signal corresponded to the Channel 7 frequency bandan Australian digital television station. Perhaps more important than that, the calculations on the altitude and speed of the reflective object indicated that It was a plane in full phase of cruiseflying at 11.7 kilometers of altitude at a speed of 792 km/h, data that coincide with the usual characteristics of a commercial flight. A problem for astronomy. As indicated in your recently published studythis type of interference represents a serious problem for astronomers, since Contamin the data and can force the elimination of large amounts of valuable information. According to Jade Chucharmefrom Brown University, “It’s like trying to listen to a friend whispering on the other side of the table while a child screams in your ear.” In this way, every time a television signal is reflected in a plane, It overlaps cosmic waves That astronomers seek to analyze, which can make large sets of observations must be ruled out. Not just that. As they underline, the team’s discovery is key to Develop interference elimination methodswhich will allow filtering these reflexes without losing important astronomical information. However, the problem is not limited to airplanes: satellites in orbit represent an even greater threat. Are we too loud on earth for astronomy? It is the big question that slides from the finding. The number of satellites in orbit It is still increasingwhich aggravates the problem of radio interference. Although scientists are improving data filtering techniques, some begin to question whether planet Earth himself remains adequate place for radioastronomy. According to poor“If we cannot find a silent sky on earth, maybe the earth is no longer the indicated place.” Be that as it may, some astronomers have begun to consider The possibility of moving radioastronomy to spacewith projects that propose the installation of telescopes in the hidden face of the moon, where the terrestrial interference would be minimal. In that sense, the discovery of Poly and his team not only solves a five -year mystery, but also marks a crucial step for the preservation of radioastronomy in an era where electromagnetic pollution is a growing problem. With the advancement of technology, the struggle between the exploration of the cosmos and the signs generated by the human being could define the future of astronomy. Unfortunately for believers, no one was watching TV in space.

Apple has been making the bulk of the iPhone in China for years. Now wants to leave … and China prevent it

by

Apple is accelerating its diversification plan for the production of the iPhone outside of China … with India as the main alternative destination. Is A story that comes from afar But now steal the accelerator. As revealed Financial Times In an extensive profile about this movement, Apple is running this movement with extreme caution so as not to antagonize Beijing, who sees with suspicion how he could lose his dominant position in the global supply chain. Why is it important. This manufacturing migration can end up being one of the biggest changes in the world economy in decades. China has been the factory in the world for two decades and Apple’s main industrial partner, but the cook company needs to minimize its risks to an increasingly tense and complex geopolitics. In addition to China, it no longer has such a cheap labor that it had a decade ago: its salaries have grown to the beat of its economy. In Xataka More and more Apple suppliers move from China to Vietnam. The problem is that there are not enough workers In figures: The Indian production of the iPhone already represents 15% of the global total. It is expected to reach 25% in 2027. Only the Chinese province of Henan exports between 50 and 60 million smartphones A year, equivalent to all the annual demand of the iPhone in its largest market, United States. The backdrop. This Apple strategy, known as “China Plus One“, the reasons began to take shape: Commercial tensions with the US during Trump’s first legislature. Logistics problems during pandemia, which They cost Apple 8,000 million in income. Chinese restrictions on the use of Apple devices by its officials. The new tariff threats after the start of Trump’s second legislature. Between the lines. Beijing is actively hindering this exodus hindering the movement of Chinese technicians towards India. It is also restricting the export of critical equipment, blocking the entry of Chinese manufacturers in India and imposing regulatory obstacles to Apple services as Apple Intelligence. India, meanwhile, is taking advantage of the opportunity: Has allocated 6,000 million dollars To encourage smartphones production. Tata, the largest Indian conglomerate, is positioning itself as Apple key partner. Tamil Nadu and Karnataka They compete for attracting investments.

China remains vital for its supply chain, but a company like Apple cannot afford to depend on a single country in an increasingly volatile geopolitical context.

The “hypercarnivore” that lived 30 million years ago and today focuses the attention of paleontologists

by

The Egyptian paleontologist Shorouq al-Ashqar and her team were about to conclude their work in the archaeological site where they worked when they noticed something that caught their attention. As explained by Al-Ashqar, it was teeth of considerable size that stood out from the rock. Bastetodon Syrtos. The teeth belonged to the fossilized skull of a mammal of about 30 million years old and belonging to a species so far unknown. The team responsible for the finding has cataloged the new species He has given him a name: Bastetodon Syrtos. The “almost complete” skull found has allowed the team to obtain valuable information about This new species. For example, let’s heal the animal would have had a size similar to that of modern leopards. B. Syrtos would have belonged to the order of the hyitodontes (Hyaenodonta), an already extinct group of mammals related to that of carnivores (Carnivora), The group in which there are species present such as cats and hyenas. The name Hyaenodonta It makes reference to these animals since, despite not having a direct relationship, the shape of the teeth of the extinct order is similar to that of the teeth of the modern species. Hypercarnivorous diet. The skull It has even served to get an idea of ​​what this animal ate. The team indicates that B. SyrtosIt would have been what we know as a “hypercarnivore” (this time in a non-taxonomic but strictly food sense), an animal whose diet would have consisted of at least 70% of meat. This species would have been, their discoverers believe, on the cusp of the “food pyramid” in its ecosystem. The team presented its finding Through an article In the magazine Journal of Vertebrate Paleontology. Etymology of a name. The choice of name is a wink in the history of the country in which it has been discovered. The Egyptian goddess Bastet embodied, Explain the teamprotection, pleasure and good health. Bastet was represented well as a cat well as an anthropomorphic figure with a feline head, similar to that that members of the newly discovered species could have had. “-Oode,” on the other hand, it is a usual suffix in zoology that means “tooth.” The fayum. Thanks to its oasis, the fayum is one of the few areas where the water dyes green the land beyond the Nile Valley, which makes it a key region for agriculture in Egypt. But there is another characteristic that makes this environment interesting: its deposits, both archaeological and paleontolocic. The new finding, in fact, has served to give context to some remains found in the region 120 years ago. From the skull found and fossils discovered in 1904 in the region belonging to hyitodars of a size even larger than that of B. Syrtos. They classify these remains into a different genre to what they have called Sekhmetops. Bastetodon and Sekhmetops. Until now these animals (whose new name also refers to an Egyptian god, Sekhmet) had been classified in the same group as European hyenodontes. The new classification places the origin of the two new genres, Bastetodonand Sekhmetopsin the African continent itself. According to the new study, these two genres would have expanded in successive waves from Africa to the adjacent continents and even to North America.
