After 80 years of peace, the European Union has a future plan for the continent: a new era of the "rearmament"

by

Europe lives a convulsive geopolitical situation. For various factors, but aggravated after Ukraine invasion by Russia. There are too many open challenges: economic pressures, commercial and technological confrontation due to the Commercial War with China (who has caught electric car already ASML in between), disunity between member states and the growing tensions with the United States. All this has been intensified in recent weeks and the president of the European Commission, Ursula von der Leyen, is clear about the way: rearm Europe. To a scrambled river … For his second term as president of the United States, Donald Trump has arrived with everything. In issues related to Europe, the billionaire has ruled on Tariffs to European productsbut has also shown interest in get with Greenland already Ukraine War. That idea of ​​getting with Greenland caused a Danish response movement so that The country will buy California On the other hand, the intention to achieve peace in Ukraine is not an altruistic movement. An objective is to stop investing in security in foreign countries. Another, power Control rare earth deposits. The reports of your presence in Ukrainian soil They seem to be outdatedbut that does not stop the ambitions of a Trump that starred last weekend A curious act with Ukrainian President Volodimir Zelenski. In Xataka The size of the armies of the main powers, summarized in this interesting graphic The gresca. On February 28 we witnessed an unusual event: a encounter between Zelenski, Trump and JD Vance, vice president of the United States. If something was clear after the heated debate Television in Prime Time is that both leaders have a total lack of tune (before it already declared that it was difficult to reach an agreement with Zelenski and Lo Lo called “dictator”). But perhaps it is more than a lack of understanding among the leaders of two countries. You cannot count on the US. The reason is that, after the event, Europe has closed rows Around Ukraine. Different European leaders have shown support to the Ukrainian leader, with quick responses such as Pedro Sánchez and Feijóo supporting the European country. The American response has not taken long to arrive. A few hours ago, Donald Trump ordered paralyze military aid to Ukraine as a punishment for Friday’s encounter. “Rearm Europe“. The anger among the leaders, who looked like an enclosure in the White House, promoted a feeling in networks among European users: you cannot count on the United States, and Europe has to act to deal with external threats. And it is not a popular runrún, but something that, from the European Commission itself, has just supported. President Ursula von der Leyen has signed a release urging member states to join the European Rearme Plan: Rearm Europe. In it, it begins by expressing two important issues: that Europe is threatened in a “real and tangible” and that it must “assume a greater responsibility for its own security.” The Ukraine War is that of drones … and robots Beyond Ukraine. After different meetings in recent weeks, the community has concluded that “massively increase defense spending”. The president refers to the situation in Ukraine and states that this measure must be taken with “immediate urgency” to support the European country, but must also be addressed to fulfill a “long -term need to assume much greater responsibility for our own security.” The plan. Thus, he has sent a letter to European leaders to raise this issue before the European Council to be held this Thursday. In it, and at the meeting, the option of using “all financial mechanisms will be discussed at reach to help member states quickly and significantly increase their expenses in defense capacities.” The intention of Von der Leyen is that it is immediate and urgent, but that it is formalized throughout this decade. In Xataka Ukraine has registered the first combined offensive of history without humans: drones and robots against Russian troops Show me the money. Of course, this type of movements require considerable investment. United States, without going any further, will invest 850,000 million dollars in defense -40% of global military spending. The way Europe would have to catch up, according to the president, is: Release the use of public funds in defense nationwide, allowing member states to have fiscal margin to be able to invest without activating the excessive deficit procedure. According to the statement, if the states increased their defense expenditure by 1.5% of the average GDP, a fiscal margin of almost 650,000 million euros would be generated in four years. Activate an instrument that provides loans of up to 150,000 million euros to invest in defense. Under the mantra “spend better and spend together”, von der Leyen clarifies that investment in air defense, antimiles, artillery systems, missiles, ammunition, cybersecurity, military mobility and something that the war of Ukraine has brought to the table should be reinforced: the war with drones and the defense against those drones. Redirect funds to investments related to incentive defense for Member States to decide, if they wish, use cohesion policy programs to increase defense spending. Finally, the option of obtaining funds through the European Investment Bank, but also with measures to mobilize private capital. {“Videid”: “X8WLH9Q”, “Autoplay”: False, “Title”: “United States vs. China: The chips war”, “Tag”: “Webedia-prod”, “Duration”: “1611”} NATO message. Among all the noise generated these days, it has survived the idea that United States abandons the United Nations Organization. The North American country is one of those who best fulfill their obligations In this sense and, recently, voices that cry out that the country should leave NATO have been raised. Elon Musk, part of Trump’s government, been One of them. The agreements stipulate that, if someone attacks an NATO country, the rest must immediately mobilize, but the latest movements of the United States and comments such as that of which They will not be foreverThey don’t help. In the statement, von der Leyen comments that the plan Rearm Europe “It could mobilize about 800,000 million … Read more

Spacex aborted the rocket takeoff for the first time from flight 1, two years ago

by

Spacex has aborted the eighth launch of Starship when there was half a minute for takeoff. Although it is a rocket in tests, this type of last minute cancellation had only happened once. A two -year run. The last time Spacex aborted the launch of a starship loaded with propelants was in April 2023. A frozen valve in Booster 7 frustrated the first attempt to launch the rocket. Almost two years have passed and now both Booster 15 and Starship 34 have given problems. The company stopped the countdown to take off of flight 8 while checking both stages of the rocket. For a moment, the clock worked again and it seemed that Spacex had solved all the setbacks, but seconds later it ended up aborting the takeoff. “Too many unknowns.” As usual, Elon Musk has been the first to offer details of what was happening between scenes. “Too many question signs around this flight”, wrote. “We were 20 bars below the required pressure level.” Musk mentioned the “Ground Spin Start Pressure”, which is the necessary pressure in the gas that is injected into engines so that the turbine turbine turns quickly enough to generate complete combustion and turn on. The next attempt. “The Starship team is determining the next best opportunity available to fly,” Spacex published After the interruptus launch. It will need to disapprove both stages of the rocket and examine them, Musk said, so the company will take one to two days to try again. In 2023, the company took 48 hours to have its facilities for a second attempt. 4,900 tons of propellants. That is the monstrous amount of methane and liquid oxygen that fits in a starship. Spacex will have to replenish the propellants in their tanks farm for a new launch attempt, which normally implies a truck parade towards the platform. First Starship from Florida in 2025. Although there has been no launch, Spacex has had time to announce a new Starships factory at the Kennedy Space Center in Florida. Gigabay will have 24 work areas and cranes of 400 tons larger than Starbase. It is expected to be operational in 2026. While building these new facilities, Spacex will transport Texas Starships to Florida and wait for the first launch of the rocket from Florida in 2025, provided that the Government approves its environmental review.

The government has been at war against sugar for years. Now he wants to ban the sale of sugary drinks in schools

by

In recent years we have seen different administrations in many different geographical areas take measures to limit the consumption of sugary drinks and other similar products, such as industrial pastries and energy drinks. The last one has come from the hand of the Ministry of Social Rights, Consumption and Agenda 2030. New regulations on the horizon. The Ministry of Consumer Ultimate vending and coffee shops in schools and institutes, As he has advanced The country. These products include industrial pastries, refreshing drinks, and energy drinks, products with more than five grams of sugar per packaged portion. The measure would also affect the advertising that can be shown in these machines; as well as the location of these, which would be out of access to students in early and primary education. More than sugar. The draft decree raises restrictions based on other criteria beyond the sugar content of the products. The measure contemplates, for example, limiting the kiloacalories by packaged portion up to a maximum of 200. This would be accompanied by an additional limit: no more than 35% They could proceed with fat. In addition, saturated fats may not provide more than 10% of the calories of the product. The salt content of the products would also be limited so that a 200 kcal portion could have a maximum of 0.5 grams of salt or the equivalent of 0.2 grams of sodium. Touring ahead. The future regulations still have to go through the State Council and the Council of Ministers before approval, which implies that the details may vary before entry into force. One more on the list. The last Biannual Aladino study, focused precisely on the Spanish child population was made in 2023. Although it observed a decrease in excess weight, overweight and obesity with respect to the 2019 report, the authors indicated that values ​​were maintained. Administrations have been serious in the fight against obesity, especially childhood obesity. Sugary drinks have been a usual target in this regard. A few years ago, for example, the United Kingdom introduced a “sugar tax” that affected this type of drinks. The resluent was a success according to a study published last year. In our closest environment the latest legislative changes in this direction have occurred at the regional level. In 2023, Galicia put on the table a proposal to limit the consumption of energy drinks among minors. These drinks, sometimes sugary represent an additional problem related to their high content in caffeine. In Xataka | We already know what energy drinks cost your rest.

We have been trying to reinvent the wheel for years. It turns out that it was as simple as replacing it with pilates balls

by

I have always seemed curious the saying “We are not going to reinvent the wheel.” It is used when trying to develop a solution from scratch instead of taking advantage of an already proven and works well. And I say it seems curious because We have reinvented the wheel On many occasions, and we continue to do so. Two examples are wheels without air And, above all, the solutions for vehicles operating on land like Mars. Although circulars, its technology and design have nothing to do with the wheels we use daily. And, okay, I accept that, being circular, we are really changing the materials, not reinventing the object. But what if instead of making circular wheels … we made them spherical? Because that is precisely what the engineer and youtuber James Bruton has built: some omnidirectional wheels that solve current problems They have motorcycles and that would also be very interesting if they apply to vehicles such as cars and trucks. Let’s welcome the wheel II To reinvent the wheel, the system should not be just an improved version of the original. As I commented, the Antipinhazos wheels They are not a completely reinvention, but a technological improvement. What Bruton has achieved could be described as a reinvention (although he has side more than one attempt). The reason? In its motorcycle prototype of the future, we not only have the two balls that make contact with the ground, but a system of three rotary mechanisms for each wheel that are really applying the necessary force to move the balls and, therefore, the vehicle. More than the spheres, the key to the peculiar movement of this vehicle are systems that rotate in opposite directions and all the time balance each other to achieve movement. Each of these mechanisms is driven by an electric motor that transfers the power, but also introduced a self -evaluated system similar to that of a Segway. In this way, it is not necessary to rely on the floor with the legs when the vehicle stops, and it is not necessary to maintain the balance in a “manual” way. Its advantages? You can go back without boosting with your legs. It has lateral displacement. You can make diagonals and turn on your axis. For a parking lot, this is great. In the video it is very interesting to see that the noise it makes is minimal, that it reaches some speed and that the mechanisms that rotate the balls are working all the time to give speed to the vehicle and to maintain balance. Imperfect, but with potential Now, it is not perfect. In the video we can see that the youtuber has trouble going straight and There seems to be a quite pronounced difficulty curve both to go forward and to take a curve. In a road situation, it would be something really dangerous because, in addition, we do not have a conventional handlebar, but a bar that remains fixed and controls rotating the handle. There is also a time when it accelerates more of the account and the balls are shot. Wow, something like that would need your own driver’s license if applied to the real world, but if the problems were solved, it is a very interesting system for motorcycles due to automatic balance. For cars and trucks it would not be a bad idea either, since they could park much more simplely. Seeing this invention, the Audi of the movie ‘I, robot’ that has similar wheels and It was a real prototype. Also the Byd video parking in parallel Thanks to nailing the front wheels and making the rear turn slowly to “skid” until the car is aligned in the parking lot. Will we adopt wheel one day like these? Whatever happens, the truth is that it is interesting how we continue to find new ways to improve something that has implanted so many years.

For thousands of years, Neanderthals and Homo Sapiens tried to mate insistently. Genetics had another idea

by

In 1856, while they worked in A limestone quarry Near Düsseldorf, two Italian workers found a basin full of bones. They thought they were the remains of a bear and approached a teacher of a nearby city, known for being a bone collector. They had no idea what they were about to provoke. The antecedent. When he saw the bones, Johann C. Fuhlrott He realized that they were not from a bear, he took the bones to the University of Bonn and, next to Hermann Schaaffhausethey communicated the finding to the world. No one took them very seriously. It was said that it was a Russian cosaco with rickets that persecuted Napoleon for Europe. Until almost a decade later, the Irish geologist William King He reached a revolutionary conclusion: we had not always been alone. But why are we now? With the discovery of Homo Neanderthalensis They opened many unknownsbut there is one that has been chasing us for almost 200 years: why did they disappear? How is it possible that such an old, so robust species, that had survived so many things disappeared without more? Why were we left alone? To all these years, scientists have given numerous hypotheses and theories. From Prehistoric genocides to A slow and agonized eclipse. However, Ludovic Slimak, researcher at the Center for Anthropobiology and Genomic of Touluse and one of the greatest international experts in Neanderthals, You have another idea. The forms of love (and what is not love). For Slimak, if we apply the knowledge of cultural anthropology to what Paleogenetics is telling us, the image is quite different. And, as in all traditional societies in which strong identities coexist, it looks like the different human communities exchanged women. From our perspective, mere expression is already a savage. But from the perspective of anthropology, those “family crossing” processes were basic to ensure stable alliances between different communities. And that, if we take into account that we are loads of DNA Neanderthal, it seems to be what happened. However, As Slimak points outthat “fusion” of lineages never came to occur. The question is why. A story (genetically) impossible. We know that Neanderthals and Sapiens crossed and They had offspring. But we also know that a significant part of it were sterile people unable to reproduce. That is, although the communities tried to lock these relationships and alliances based on miscegenation, the thing did not work. Searching. It’s curious, Slimak said in An interview for Livesciencethat “when you are looking for old DNA (40,000 to 45,000 years ago) all these sapiens early have recent DNA, and That is why we have (DNA Neanderthal) today. But when you arrive and try to extract DNA from the last Neanderthals, contemporaries of these first sapienslet’s say between 40,000 and 50,000 years ago there is not a single Neanderthal with DNA sapiens“ Curious and very possibly one of the keys that explain because the most numerically and genetically diverse population of Sapiens won the departure to the Neanderthals. That is, why we were alone.

The US believes to have a “treasure” with the rare earths of Ukraine. Everything is born from a outdated Soviet report 50 years ago

by

Today, Friday, February 28, Presidents Volodymir Zelensky and Donald Trump They will meet in Washington to discuss and sign the agreement on the mineral resources of Ukraine. This alliance will give the United States a control over the country’s natural resources, a measure that Trump has promoted These last days. However, estimates on this aspect are based on reports of the former USSR for more than 50 years ago. The famous “rare earths”. I think we have heard of the “rare earths” these days and, in this same medium, We have deepened the subject Exposing the arguments of two energy experts, which have confirmed that talking about “rare earths” is a mistake. However, the global S&P medium He has been able to demonstrate Where does that speculation come from, it has only had to dust off some old documents of the former Soviet Union. More than 50 years ago. The geological report of the Soviet era that is using Ukraine to evaluate its “rare earth” deposits focuses on an exploration made between 1960 and 1990. It is true that the technology of the moment and the methods were very different from the current ones. According to experts Consulted by S&P Globalthe data used to estimate mineral resources have not been updated since the dissolution of the USSR in 1991. In addition, some of the deposits are in areas of difficult access and require more advanced technologies for extraction, as is the case of Novopoltavske, located in the Zaporizhia region, due to hydrogeological mining conditions. This mine, according to the report, contains phosphates, rare earths and niobium. On the other hand, currently, you cannot access the territories occupied by Russia, as in the Donetsk region, where the Azovske and Mazurivske quarries are located. Were these deposits exploited in the USSR? According to the report with more than five decades, they knew about them and explored them, but were not completely exploited on a large scale. The impediments went through a lack of structure, the complexity to access the deposits and technological limitations of the time. After the dissolution of the USSR, the mining projects in the Ukraine area stagnated and no attempted development was made in a postsoviet era. What will happen today? United States and Ukraine They will sign a treaty For a Ukraine reconstruction fund, partially financed with the income of its mineral reserves. Ukraine has agreed to contribute 50% of its future income derived from critical mineral mining such as cobalt, lithium, titanium and rare earths. In return, United States It would help develop The mining infrastructure necessary to extract these resources, but analysts consider that real benefits could take many years to materialize. In addition, the US will be co -owner of the Fund to the extent allowed by its legislation and promises long -term financial commitment, but the agreement It does not specify amounts, deadlines or details about the management of the fund, which generates uncertainty about its real implementation. However, there is a key fact that has been overlooked: currently, Ukraine does not produce rare earths at the commercial level. Although it has reservations, the infrastructure necessary to extract them still does not exist. According to the United States Geological Service, Ukraine has Scandio depositsone of the 17 elements of rare earths, but its large -scale extraction has not begun. Is it really so essential for the US? We have already told. On the one hand, Trump seeks to lead global mineral resources and impose himself on China. On the other hand, analysts They have mentioned that Ukraine should produce 20% of the world’s rare land for more than 150 years to reach the 500,000 million dollars of value that Trump has mentioned. In addition, as indicated in the report, the value of deposits may not justify the investment in its extraction, which makes Trump’s interest not completely clear from an economic perspective. To this is added the lack of clarity On the previous help of the US: Trump has mentioned between 300,000 and 350,000 million dollars, but the Kiel Institute has estimated that the real figure is 119,000 million. It should be remembered that Ukraine has a notable production of other strategic minerals. Before the war, Galio produced, used in semiconductors and biomedical applications, and contributed 2% of the world’s bromine production, essential in flame retarders. In addition, it produced ilmenite, a key mineral concentrate for obtaining titanium, a metal with military applications. However, the war has stopped the production of manganese and alumina, fundamental for the manufacture of steel and aluminum. And about the occupied territory? Access to mineral deposits in territory occupied by Russia depends on an eventual resolution of the conflict, adding another layer of uncertainty to the agreement. It also follows a key issue in the air: Zelensky sought to include security guarantees for Ukraine, but The agreement does not explicitly mention them. Although the text says that the US will support “Ukraine efforts to obtain security guarantees,” does not establish specific commitments or defense mechanisms in case of aggression. Without them, the real impact of the treaty remains uncertain. Trump and Putin. All this conflict is even more complicated if we add the layer of the relationship between Donald Trump and Vladimir Putin, who have talked again, and the Russian leader even has offered preferential access to the natural resources of your country, showing willing to negotiate the end of the conflict. Despite these “advances”, the possible concessions that Trump could accept, such as Ukraine renounces NATO, they worry both kyiv and Europe. They fear that these agreements can make safety in the region even more unstable. And the cake wid. The agreement Mention explicitly That future negotiations on the fund should avoid conflicts with the process of adhesion of Ukraine to the European Union, a striking point given Washington’s growing antagonism towards Brussels. However, Zelensky wants to avoid that the agreement interferes with its ambitions in European integration. Everything remains to be seen at today’s meeting. Image … Read more

After years with its closed borders, North Korea has opened to foreign tourism. The price: more than $ 600

by

Very shy, limited and with restrictions, but North Korea begins to open to foreign tourism five years after have sealed its borders to protect yourself from the propagation of COVID-19. The hermetic nation led by Kim Jong-un is about to be somewhat less hermetic, both for travelers from China and Western. Of course, at least for the moment and despite the fact that the country is building His own ‘Benidorm’ In Wonsan, the tours will focus on a specific (and controlled) area: Rason. No visits to Pyongyang. Border closure. Five years ago, even in the initial bars of the Covid-19 Pandemia, North Korea took A radical decision: At the end of January 2020, the view of how the virus spread for the Chinese neighbor, the authorities decided to close foreign tourists. The measure made sense if one takes into account that in 2019, tens of thousands of travelers arrived from the Asian giant had visited North Korea. Some sources speak of 350,000. Others point out that the country received in total 300,000 tourists foreigners, of which 90% were Chinese. One (long) temporary measure. The idea was that the borders remained “temporarily” as “preventive measure against coronavirus.” Or so He announced it In January 2022 Young Pioneer Tours, an agency that was dedicated to organizing trips to the country of Kimg Jong-un. What was not clarified was what exactly “temporary” meant, an uncertain horizon that extended one, two, three … until five yearswhich is what has ended up lasting the closure. The government already made A first gesture In 2024, allowing Russian tourist delegations, which were already pointed out as The first foreign travelers who accessed the country from the pandemic; But now North Korean authorities have decided to go one step further. Coinciding almost with the fifth anniversary of the closing of the borders, the country has allowed The passage of several travel companies and a very small group of visitors. What exactly? The Straits Times Explain that at the beginning of February the North Korean authorities allowed the country of a select group of travel operators. Select and Very small. Experience served to tote the land for the really important date: tourism reopening February 20although the latter has also been done in a limited way. Among the operators who stepped on North Korean soil after years of border closure was the Australian Rowan Beard, of the Pioneer Tours agency, based in Beijing. His business was expected to take A dozen tourists To the country, a figure similar to the one that was handled by another of the selected operators, Koryo Tours, who when Corea’s apartment already had a group of 15 people eager to walk around the country. And who have visited it? After the first trip of recognition and “familiarization”, that of Beard, foreign tourists have arrived, including people from Singapore, Australia, Germany or Romania, according to Precise The country. Other media They holdthat among visitors there are also citizens of the United Kingdom and Jamaica. The CNN even assures That among the “pioneers” is an American, Justin Martell, who would have mocked the prohibition of his country after becoming a citizen of Saint Kitts and Nevis, a Caribbean nation. Looking at China. After A first approach To Russia, the nation of Kim Jong-un already looks at its great tourism market: China. Kyodo News agency I advanced A few days ago the country prepares to resume tourist trips of the Asian giant, which until the closing of borders moved a flow of tens of thousands of travelers a year. The perspective of knowing North Korea may be more or less appealing from countries such as Spain, where the government even advised The visitbut it has its market. Packages for $ 670. Beard remember that when his agency announced the trips the company’s email “saturated” consultations. And that the experience requires scratching the pocket: Young Pioneer Tours, one of the few authorized, offers a five -day and four night package for $ 670. Another option is to pay $ 720 With several nights in Yanji, China. “For many people it is a very mysterious country,” Beard comments: “Technically there is no Internet or is limited. So life there works in a similar way to what we had in the 1980s.” Those who have already been in the country after reopening ensure that the rules when taking photos have relaxed, which does not mean that visitors can film what they want. “They only scold me once,” Recognize the CNN Gerg Vaczi, by Korko Tours, “and was to film a guide.” Opening, but with quotes. North Korea’s policy change has been important, but also limited. That he has decided to allow the passage of tourists again does not mean that they will move freely through the country or move to the capital, Pyongyang, supposedly closed For any tourist who Do not come from Russia. Visitors must settle at least for the moment with Rasona special economic zone established in the early 90s and presents certain important peculiarities. A special destination. To begin its location, it is strategic, northwest of the country, near the borders of China and Russia. It also does not have an international airport, with what the only way to arrive is to cross the limit with China under the control of the Border guards. The area also has peculiar administrative conditions and has been raised, Precise ABC News, as a kind of evidence field to test new economic policies. The idea It is that tourists who can reach drops visit spaces such as a factory, an aquaculture farm, Schoolsor have the experience of open an account Banking in the Golden Triangle Bank. Rason is also in a border and coastal area. Beard Recognize In any case that the area presents certain “logistics limitations”, such as the number of hotel places, guides and buses. And why now? The other big question. It is estimated that before the pandemic the country received hundreds of thousands of Chinese tourists generated … Read more

The eight years of updates are already possible on Android. That will happen is something very different

by

Who was going to tell us a few years ago that a phone could be updated up to eight times to a new version of operating system. This is precisely what Google and Qualcomm have just signed, supporting updates for eight years to all those manufacturers that incorporate the Snapdragon 8 Elite on your phones. “This means that the support for platform software included in this program will be available for OEM for eight consecutive years, including updates of the Android and Kernel operating system, without the need to make important changes or updates on the platform and the code OEM of the device (a separation commonly known as “project treble” or “supplier implementation”). Update of Kernel mode controllers, the supplier code can remain unchanged while providing software support. “ Updating for eight years sounds very good, but it is difficult to end up becoming a common practice. Manufacturer’s decision. Qualcomm and Google have opened the door, but it is the manufacturers who decide whether or not. In fact, Qualcomm itself makes it clear in its statement. “The original equipment manufacturer (OEM) will decide if a smartphone or an eligible mobile phone will receive all software support offered For longer. “ Last year, Qualcomm already endured Seven years of updatesand just Samsung and Google got on the car. Among all Android manufacturers, these two are the only ones that offer seven -year updates from the date of purchase of the device. A small shot in the foot. Updating a phone for seven years is a complex matter. On the one hand, it is a great sale argument. If we think of brands such as Samsung, Google or Apple, the first thing that can come to mind is “longevity.” They are phones made to last, and when we are looking for a high -end phone, this point is key. But, on the other hand, support for eight years involves dedicating eight years of resources to a telephone that will stop selling after their first year of life. That is why the vast majority of manufacturers still do not offer a wide cycle of updates. Manufacturers such as Xiaomi and Oppo offer four years of system updates. Others, as alive, stay in three. The battle with the annual model. We have been raising a movement that a priori would make sense: stop launching a year a year. The technological maturity of the smartphone is increasing (even more in the highest ranges), something that makes it difficult to see relevant innovations. If a phone is going to last eight years, a renewal cycle every two years is not crazy. Despite this, launching annual devices remains a strategy to boost income and grow the manufacturers ecosystem. Not only will it be high -end thing. “The smartphones that are launched with the new mobile platforms of the Snapdragon 8 and 7 series will also be eligible to receive this extended support.” Qualcomm has not detailed which series models seven will be compatible, but opens the doors for mid -range models also have an extensive life cycle. Great news about the paper, although it will remain to be checked how many manufacturers update a phone away from the first line.

The oceans of the Earth were green for thousands of years. More and more scientists believe they will be again

by

On February 14, 1990, 6,000 million kilometers from Earth, the Voyager 1 He took a photo. There, sustained in space by the mysterious forces of. Space-time, our planet is nothing more than a light blue motor between the sunlight reflected by the camera. Four years later, Carl Sagan baptized that photo as “that pale blue point.” What we just discovered is that it was not always the case. 3,000 million years ago, that point would have been green. Wasn’t it blue? Actually, according to Taro Matsuo and his team from the University of Nagoya in Japan explain in Japanduring most of the history of the earth its surface would not have been blue. For about 3,000 million years and until 600 million years ago (just when complex life begins on the planet) the predominant color seems to have been green. (No) take iron from the matter … The first is that, at that time, the indications tell us that the oceans were full of iron hydroxide. This inorganic compound absorbs blue light. In addition, naturally, water absorbs red light. That means that taking into account that chemical composition, the only free light was the green color. The other reason is the cyanobacteria. It’s about One of the first photosynthetic beings of history and not only used chlorophyll to absorb sunlight, but used fuses to absorb red and green light. The sum of these two things caused the seas to have a characteristic green color. And they had it for billions of years. It is true that it was not a pure green color. After all, blue is “a consequence of dispersion Rayleight of sunlight in the atmosphere. “So the color would tend to blue, but without a doubt it would be something much greener than current. What is the use of all this research? First, to understand that when The MIT explained in 2019that the sea will return green in the mid -century, we are talking about something very plausible. It is not just that A follow -up study In 2023 he confirmed that more than half of the land surface had gained greenery in recent years. It is that, for a long time, it was so. On the other hand, it allows us to answer one of the great questions of astrobiology: “Does only the blue tone of a planet serve as an indicator of its potential to house life?“And the answer, of course, is no: not a ‘non -radical’ is true; but one that reminds us that there are more things out there that can still dream our biology.

“I have found a really admirable demonstration, but the margin of the book is very small to put it.” It is what the 17th -century French mathematician Pierre de Fermat wrote when stating his His “last theorem”. Fermat’s problem took three decades to be found between the mathematician papers and three centuries until that admirable test was discovered. And yet the case is not entirely settled, only that the challenge is something different. Take it to a computer. He New challenge It is to make a computer to try the elusive theorem. That is the objective of a new project, FERMAT FORMALISINGled by Imperial College London. Fermat’s problem. Fermat’s last theorem “postulates that, if A, byc are natural numbers and not equal to zero, the an+bn = cn equation has no solution if n is greater than two. Formally demonstrating something is not as simple as trying it by rehearsal and error, and this demonstration, too complex for the “megish margin” of the Fermat’s notebook would be lost for centuries. The problem was resolved in 1994 by the British Andrew Wiles, who had begun to solve this puzzle with only 10 years. In 2016 Wiles was awarded the ABEL award, the award considered “The Nobel of Mathematics.” Almost one million pounds. Another 30 years after the resolution of the enigma and more than three centuries after the death of Fermat, a team of researchers, led by Kevin Buzzard, of Imperial College London, has put to work to take a different step, teach A computer to solve this problem. The new project It began at the end of 2024 and will last until 2029. It has a financing of just over 934,000 pounds and already begins to give some results, in the form of code fragments that are added to a Database in Github. What remains to be resolved.It can be contraintuitive, but this type of reasoning, which lead us to formally demonstrate mathematical theorems, are difficult to teach computers. Recently, Buzzard and other experts They explained the complexity of the matter to the French newspaper I monde. To begin with, we must take into account that the resolution of this theorem is complex, it is no accident that several generations of mathematics would turn the brains trying to find it. These mathematicians also had previous experience in the field of resolution of these types of problems. As Buzzard explained to the French newspaper, mathematicians have a base that allows them to “jump steps” when explaining the resolution to this problem. A computer, however, must start from scratch when building its own explanation for the matter. And all this, for what? “Fermat’s last theorem (…) has no applications, theoretical or practices, in the real world,” Buzzard pointed out A few months ago to the magazine New Scientist. So why so much effort to teach a computer to solve something we already resolved? The key here is not in the past but in the future. According to Explain the team at the head of the projectcomputers today can be used to attend mathematicians trying to solve problems such as demonstration of theorems, but there is an obstacle to materializing some forms of help. The problem, they point out, is that few mathematicians have focused on working with this software, so there are no tools that have the “definitions” used by mathematicians to solve these problems. Working on this problem should be used to create the necessary databases for solving similar problems in the future. In Xataka | We had more than a century trying to solve some mathematical problems.
