Samsung is committed to fighting with nails and teeth the most powerful mobile chip race. The perfect candidate finally has

The world of semiconductors has a look set on the next generation of integrated circuits manufactured in lithographic processes of 2 nm. Meanwhile, the most advanced processors for mobile phones continue to use the 3 Nm processes. Giants such as TSMC have demonstrated their good work with proposals such as Qualcomm Snapdragon 8 Elitehe Apple A18 Pro Apple, and even the Xiaomi Xring 01. Now it is Samsung’s turn. The company has presented its Exynos 2500and it is much more than a processor. It is the company’s great opportunity to dissipate doubts about the performance of its mobile chips, one of the keys for the company’s semiconductor division to remain alive. Between surrender and reinvent the design of its highest range mobile processors, Samsung has chosen the second option. Why is it important. The Samsung Exynos 2500 It has been playing since last yearwith a production that did not enter into mass for the low performance he showed in the leaked tests. Going forward with the proposal does not show only that Samsung trusts this proposal: it is a message to the world about the point where they are and can become semiconductors. The company has not revealed what device this processor will premiere but, taking into account that there are Rumors on the table about a new unpackedit is more than likely to know him soon. The exynos 2500. I will not get bored with excessive technical data from the processor. Your keys are summarized in a simple way. It has a ten -core design, just like Xiaomi’s own processor. It is the only high -end processor, next to the Xring, with this design. It is its greatest particularity. Promises to be 39% more powerful in the process of AI. Supports cameras of up to 320 megapixels. It is built in the 3 Nm GAA process. Its largest nucleus is up to 15% more powerful than its predecessor. The main doubts are how these numbers will be translated in real use. Its architecture is quite similar to that of Xiaomi Xring (with Cortex X925, A725 and A520) and a Samsung Xclipse 950 GPU that will have to compete with the best adreno. The message. Ten -core CPU, cameras of 320 MPenergy efficiency and improvements in AI. Samsung has not fallen excessively Marketinians nor has he made promises that he cannot fulfill. It is a more powerful processor than the previous one, centered on AI and with support for the best technologies of the moment. The rest is about to prove. The key to Samsung. Samsung has been facing problems with its semiconductor division for years. Lose clients like Google To provide the pixel with their processor, it is one of the most recent blows, and survive to arrive with decent performance to the 2 Nm career is crucial for the future of the company. The company has delayed two of its most important projects today: the construction of its second manufacturing plant of avant -garde chips in Taylor (USA) and in Pyeongtaek (South Korea). They are projects that are still underway And they will be key to the development of their semiconductors but … it will use without customers. Exynos 2500 is the most recent test of the point where Samsung is in mobile chips. If it fails, the company will have it more difficult than ever to continue attracting investment.

Apple believes that its rivals are not doing well in ia. It is the perfect excuse to delay Siri one more year

We already have news about the arrival of the expected and Nueva Siri. They are not good. Apple points to the spring of 2026 as a launch objective for its new assistant, with the aim of bringing it as part of the update to iOS 26.4, According to Bloomberg sources. The delay is completely in line with The recent interview of Wall Street Journal Craig Federight and Greg Joswiak: Apple knows that he is losing the AI ​​career, and he only has trust that your proposal ends up working in the long term. They painted you little birds in the air. It has been just one year since that presentation of Apple Centered in Apple Intelligence. One in which they told us about an integration of Siri in the system as we had not seen: an assistant with the ability to understand each corner of iOS, with an advanced contextual understanding and integration with each native app of the system. In principle, the final deployment was planned for autumn of 2024, but the delays accumulated and accumulate until they reached a practically unsustainable point. iOS 26 as first real step. Apple took advantage of the WWDC 25 To present iOS 26, one of the Greater changes at the visual identity level Never seen in Apple’s operating systems, now much more unified. Next to him, they finally arrived Artificial Intelligence Functions Applied to everyday use: although for practical purposes they do not go far beyond the translation of texts, filters for calls and some improvements in the generation of genumjis in image playground. After almost a year of delays, Apple finally implied what is its philosophy with AI: work to make it local, but with a functioning similar to that of its rivals. More delays. After the presentation of iOS 26with novelties in AI but not a single word about the new Siri, the question was forced. What is happening with her? The responses of a Craig Federighi, nothing height but not entirely comfortable, perfectly revealed the moment in which Apple is. (Joanna Stern) “Siri is not better than his competition”, (Craig Federight) “already, but it will be, it is our mission.” (Greg Joswiak) “It would be disappointing to launch something that does not meet our quality standards.” (Craig Federight) “This is a new technology, nobody is doing very well right now.” Joswiak, software leader in Apple, justified its road map around the key point: the company wants its AI to be discreet and that the user can perform tasks with the phone without even realizing that he is using Apple Intelligence. In fact, they do not want a dedicated app, as there is for Gemini either Chatgpt. The problem? Google has achieved this goal for a long time. Apple’s rivals are doing well. Although Apple points to the immaturity of the AI ​​for mobiles, the truth is that one of its best moments lives. And phones like Google Pixel or the Samsung Galaxy S25 Ultra They are the best proof of this. Here you have to make a distinction between Gemini as an app integrated in the system, and with Gemini Nano as a language model. On a telephone like the Ultra S25 can: Translate real -time calls without knowing that AI is doing. Remove the background noise from a video automatically, without Gemini telling you what you are doing. You can transcribe a voice recording with a single click, without opening additional applications. If they call you, the phone will automatically detect whether or not spam, without notices about ia. Yes, Google (although its approach is not so local), is able to integrate Gemini silently into the system. So much so that their functions are still native to the system, and the user does not have to know what is done with Ia and what not. Apple needs to overcome Gemini at AI. It will not be easy. Apple, for now, has not shown to live. During the presentation of Apple, Its action fell 1.5%. The expectations were high, but the presentation was a clear Apple message showing not being above any of its direct rivals, and relegating third parties (OpenAi) the most advanced functions of AI. With the looks put in 2026, the pressure to which Apple is subjected is even greater. The maturity point of its main rival, Google Gemini, is very highabove proposals in Benchmarks regarding Grok 3, O3-mini, Deepseek R1, Claude 3 and calls 4. To recover Apple confidence needs results, not promises.

Europe fails to find the perfect solution for cross -border payments. Bizum and Banco Santander have just put it on a tray

Santander has become the first Spanish bank that allows its customers Send Bizum to other European countries. It is something that is achieved thanks to the interoperability between Bizum, Bancomat and MB Waya connection that according to the bank will connect 50 million users and 186 financial entities. It is a first step waiting for a unique pawous solution for which no agreement is reached. The first in Spain. Banco Santander has formalized the possibility of sending money through Bizum in a cross -border way. The agreement has been necessary between different payment solutions such as Bizum (Spain), Bancomat (Italy) and Mbway (Portugal), being limited instant payments to these two countries, for the moment. After performing the corresponding successful pilot tests, the clients of this bank will be the first to be able to pay outside Spain. The method will be the usual: we will only have to write the mobile number of the user to which we want to send the payment, and this will be carried out immediately and without commissions. It will not be alone. Santander has been the first to move token, but the possibility of sending Bizum out of Spain will be a standard before summer. Abanca, OpenBank, Caixabank, BBVA and Banco Sabadell are advancing in the implementation of this service, planned for the second quarter of 2025. It has not been thanks to Europe. While Europe Follow in search of a unique solutionthe private company moves record. Cross -border payments are possible thanks to the European Initiative (European Payments Alliance), a joint project initiated by Bizum and followed by both Bancomat and MB Way, with the aim of adopting instant transfers paneuropeas using existing infrastructure. In other words, it has been necessary for those responsible for the platforms to agree, in the absence of a European alternative that encompasses. The European Bizum. The European Central Bank has been trying to advance in a system of instant payments to interconnect the different member countries. But he doesn’t get it. During the last two years we have seen progress as Free transfers in Europe, Tests with digital purseand brushstrokes on a “European Payment Initiative” which has barely advanced since 2022. Countries like Spain They make 95% of immediate payments with Bizumbut this is not the only name that sounds as a candidate for possible means for European payments. There are those who try strongly. Solutions such as Bizum, Bancomat, BM Way or Swish were born as responses to the national need to be able to pay freely and free. The problem for the EU? None have been thought from scratch as a single payment solution. This is where solutions such as Weroa proposal towards “a unique payment solution, all in one, instantaneous and paneuropea, capable of covering over time all cases of payment that consumers and professionals require.” Banks such as German and French They are already promoting this servicenot yet compatible with solutions like Bizum. Nothing clear. The ECB points out that “instead of combining strength and sharing resources to develop paneuropeas solutions, national communities have often preferred to preserve the legacy of the investments made in the past”, an attack on models such as Bizum and a clear look at proposals such as Wero. With many delays and few proposals on the table, the road to a “European bizum” continues to draw distant. But, meanwhile, in Spain we will not take to pay with virtually any bank outside our borders.

This camera as small as ambitious is not perfect, but almost

There are cameras that arrive with so much noise that it is impossible to ignore them. The DJI OSMO POCKET 3 It has been one of the most commented in recent months by its size, its versatility and its surprising performance for video. But … is it as good as they say? In this New 24/7 episode published in the YouTube channel Se xatakaour partner intends to find out: record with her for a whole month as the only main camera, getting to record resources for videos such as the Versus of the Samsung Galaxy A56 against the iPhone 16E. “I have asked to use it only as my main video camera,” he says at the beginning. Neither loose tests nor support clips: a real and continuous use. What comes from there? The first thing that attracts attention is how much such a small format can give. “The first time I saw the Osmo Pocket I judged her quite bad Because I thought something so small could not record anything well. ” And yet, the thing changes after several days recording real plans for other Xataka videos. There are strengths that do not take long to appear. The stabilization of three axes, the automatic approach, the Face Track mode. “It works quite well, it is fast and does not have many failures.” And the design with folding OLED screen 90 degrees makes you record yourself as simple than it seems. But there are also decisions that surprise. And not for good. What about the digital zoom? And why can’t you record vertically without trimming resolution? The camera allows you to record vertically, but it does so digitally the image. And although that can be enough for social networks, It is not ideal To get the most out of the sensor. How is it possible that you have to install an APK today if you use Android? Throughout the video, advanced functions such as recording in logarithmic, settings in 10 bits and wireless microphone performance are tested. There is also talk of autonomy, fast charging and accessory pack. At this point, it should be specified: autonomy is approximately an hour and 50 minutes recording at 4k at 60fps, which can be extended up to about 3 hours and 20 minutes with the battery grip. Now, not everything is as round as it seems. And some things could directly improve. As for the zoom, during the first tests it offered quite poor results, but after a Firmware updateDJI has managed to improve. It is not perfect, but at least now it is usable in specific situations. “It is one of the most useful and comfortable cameras that I have ever tried to create content,” concludes our partner. But that means that it deserves what it costs? And that has no rival in its format? Give it to the play. Because this time, the 24/7 is for this interesting camera. And if you want to know more about other outstanding devices in the world of photography, we invite you to read our articles about the Canon Eos R1 and OM System OM-3.

be the perfect candidate for each position

In the same way that you would not be able to play a game of Soccer with moccasinspersonnel recruitment experts recommend Adapt the curriculum to the job offer to give Priority to skills that the company claims. This Curriculum adaptation It is a basic strategy when applying to any job offer today. In the early 70s, Bill Gates used that same strategy to Adapt your academic skills In registration applications for Yale, Princeton and Harvard universities: three universities, three different Bill Gates. An actor: three characters In his autobiography ‘Code Source: My beginnings’Bill Gates tells how he faced his admission application in some of the best US universities. Although in the case of the young Gates it was almost a joke with himself, his strategy, reminds to which any candidate who runs to a job offer should do. In autumn of 1973, Bill Gates participated in a play during his last year of high school. It was there when he discovered in the theater a new way of relating With other young people and show aspects of your personality that were in the background in other activities that were usually carried out, such as programming or making long excursions through the mountains. Just then, Gates had to send income requests for universities. That raised some doubts about what his Labor future. The options that were raised were to go to Harvard and follow in the footsteps of his father as a lawyer; orient towards a more political profile studying public administration at Yale; or go to Princeton to train as an engineer and develop software, something he had already done His first steps. Bill Gates tells in his book that “while filling the requests, I experienced with my personality. As I had learned in the theater class, each was a performance: An actor, three characters“The millionaire said. “For Princeton I said that I wanted to be an engineer who knew how to develop software. I boasted with examples of my programs and emphasized my mathematics notes. To Yale I said that I wanted to study public administration and, perhaps right, highlighting my experience (like Ujier during a couple of summers in Washington DC), my fondness for the boy scouts and my interest in dramatic art.” However, the request that had more weight for Gates was the one he presented to Harvard, “as I wrote in my essay, I expressed my inclination for business and law,” following his father’s professional steps. All gates, all certain Sincerity It is something that recruiters They value very positivelyso adapt the curriculum for a certain position It does not imply lying in skills, but to give priority to those who have A positive impact In the position to which it is postulated. “We expect sincerity. If a person comments that he is good to work as a team, but in the day to day he avoids participating in meetings, that is where we see that there is an incoherence with what he explained in the interview,” he explained Lidia Sanz CostaTechnique of Selection, Development and Training in companies IMAN. The “Three Bill Gates” presented by the millionaire in their respective income requests They were realbut little was going to serve a software engineer to have learned the values ​​of the scouts, or have knowledge of dramatic art. For that reason, the young Gates arranged to play a paper highlighting only the skills that They contributed value to their candidacy. In this sense, it is increasingly common to use the help ofChatgpt to adapt the curriculum to a specific job offer. This automation applied to curricular adaptation will also take into account other factors such as including Keywords and skills what would priority to office, preventing them from candidate monitoring algorithms (ATS) Believe your curriculum In the first rounds of the process.

Wild urbanization, heat and cockroaches have turned Brazil into the perfect destination of a creature: scorpion

In Brazil they have realized a serious problem derived from a common evil in a large number of countries. It was intuited that Wild urbanizationadded to the climatic changes And the extreme heat of the planet were an equation that did not predict anything good. The nation has discovered, very much, something else. The atmosphere of many of its cities has led to authentic cockroaches colonies and, after them, those that devour them: scorpions. Silent invasion. Yes, Brazil is currently facing an alarming Scorpion proliferation In many of its cities, a direct consequence of uncontrolled urban growth and climate change, which has transformed urban environments into ideal habitats for these arachnids. How much? According to the study Posted in Frontiersbetween 2014 and 2023, more than 1.1 million bitesa 155 % increase In just a decade, and the projections estimate up to two million new cases between 2025 and 2033. The situation is especially critical in densely populated areas and with precarious services, Like favelaswhere the combination of crowded housing, accumulation of waste and sewerage systems without control has created the perfect scenario for the expansion of scorpions. These creatures find shelter in cracks, debris and pipes, have abundant food (The cockroaches), and enjoy constant temperatures and high humidity. Plus: Some species are capable of reproducing without mate and can survive more than a year Without feeding, which makes them a resistant threat and difficult to eradicate. A public health crisis. The Guardian told that the increase in temperatures, intense rains and prolonged droughts (increasingly frequent patterns in the context of climate change) have favored the expansion of scorpions, whose natural habitat is now complemented by those Modified urban environments For the human being. Previous investigations had already warned of these animals for adapt to citiesbut current data has confirmed that the phenomenon has climbed to become a health crisis. Only in 2024, it is estimated that almost 200,000 people were chopped And at least 133 died, although experts warn that real figures could be much greater, since many affected do not seek medical attention and are treated at home. Although only 0.1% From the bites it is lethal, the most vulnerable victims are children and the elderly, who run a greater risk of dying even with a single sting. For the rest of the population, the symptoms include intense pain, burning, swelling, redness, tingling and nausea, with a recovery that lasts several days. Misinformation and prevention. And here comes one of the legs to deal with the problem. The British media counted That one of the most complex challenges is the erroneous perception of scorpions. According to researcher Manuela Berto Pucca, they are not natural aggressors of the human being, but They act in self -defense. In fact, they perform key ecological functions when regulating populations of urban insects, yes, such as cockroaches. However, its presence in inhabited spaces has generated an understandable and growing fear, especially among the poorest populations, where the fear of a bite is part of everyday life. The key, According to expertsis in prevention: keep the spaces clean and without moisture, seal cracks, place grilles in drains and carefully check footwear, clothing and towels before wearing them. In addition, the Brazilian health system offers Free treatment and antidotes in certain emergency centers, but researchers insist on the need to act quickly at any sting, without waiting for symptoms to get worse. A call to action. Finally, it should be clarified that the phenomenon It is not exclusive from Brazil. Countries like Paraguay, Bolivia, Mexico, Guyana or Venezuela too They have experienced a worrying growth of “Scorpionism”, The medical term that defines the reactions to these bites, making it a health crisis of regional scale. And in Europe? There are more than 35 native species of scorpion, but there are no comprehensive studies on their populations or comparable expansion has been observed. However, what is happening in South America serves as a global warning on the combined effects of that uncontrolled urbanization and climate change. The international scientific community has stressed that this is an avoidable emergency if more sustainable urban policies are applied, effective sanitation systems and public education and prevention campaigns. For Pucca and his colleagues, the current situation should serve as a catalyst for urgent actionsnot only to protect public health, but also to recover the balance between humans and the rest of the urban ecosystem to which these creatures also belong.

In the exciting world of the supernovas this newly discovered has something unique: its form is perfect

Identifying a Supernova is an event that astronomers usually celebrate with enthusiasm. And it is not for less if we consider that it is One of the most violent events with which we can run into the cosmos. Knowing them better is very important because it can help us understand more precisely what the latest stages of The life of mass starsand also the mechanisms that explain how the material caused by stellar synthesis can lead to new star systems. The mathematical tools handled by astrophysics current nuclear fusion that take place in the nucleus of mass stars. During the stage known as the main sequence, stars obtain their energy from the fusion of hydrogen nuclei. As this chemical element is consumed, the star begins to produce helium nuclei, and, of course, its composition begins to evolve. During this process a huge amount of energy is released and the star is forced to continuously readjust to maintain hydrostatic balance, a phenomenon that is the result of the coexistence of two opposite forces capable of compensating. One of them is the gravitational contraction, which compresses the subject of the star, pressing it without rest. And the other is the radiation and gase pressure, which is the fruit of the ignition of the nuclear oven and tries to expand the star. ‘Teleios’ is the perfect supernova If the star is massive enough will begin to consume its helium reserves and produce new carbon nuclei, while maintaining the hydrostatic balance we have talked about. And if the star has enough mass will not stop in carbon production. When this element is exhausted in the nucleus, it will be readjusted, compressing and increasing once again its temperature to stop the gravitational collapse. From this moment the carbon nuclei will enter into ignition through nuclear fusion processes and the production of even heavier chemical elements will begin. While in the star’s core is being carried out Carbon fusionin the immediately superior layer the ignition of the helium is maintained. And above this, of hydrogen. The iron core suddenly contracts under the enormous pressure that all layers of material that it has above the material exerted on it During star nucleosynthesis, stars acquire a layer -shaped structure similar to that of an onion. In the nucleus lies the heaviest element, and from there we are ascending by layers finding more and lighter elements. If the star has accumulated sufficient mass there will come a time when the nucleus will be essentially constituted by iron, and from this chemical element it is not possible to obtain more energy through nuclear fusion processes. At that time the radiation and gase pressure is not enough to counteract gravitational contraction, so Iron core suddenly contracts under the enormous pressure that all layers of material that it has above. The star has lost the hydrostatic balance. At this moment all this matter loses the support that the nucleus exercised, which is now much more compact, and falls on it with enormous speed. When all that star material touches the surface of the nucleus there is a rebound effect that causes it to be fired with a huge energy towards the stellar medium, being disseminated. A supernova has just been produced. Some of them are so energetic that for a few seconds they emit more light than the entire galaxy that contains them. This was probably what happened to ‘Teleios’, the remnant of a supernova recently discovered by an astronomer team from the University of Sidney (Australia). The remnant is nothing more than the material that is spread in a region of space after the production of a supernova In the field of Supernovas, the remainder is nothing more than the material that is scattered in a region of space after the production of a supernova. It usually acquires the shape of an expanding bubble in which it is possible to identify an external and brilliant region in which the shock wave and a diffuse interior section occurs constituted by dense and cold dust and dust. The image we publish on the cover of this article recreates a supernova in the most reliable way possible, and in it we can clearly observe the two regions in which we have just inquired. Astronomers from the University of Sidney have identified the remnant ‘Teleios’ using the Australian Askap telescope (Australian Square Kilometre Array Pathfinder), and have realized something very interesting: its geometry is almost perfectly circular. It is very unusual that the material left after the production of a supernova acquires such a perfect geometry. Although these astrophysics shuffle several scenarios that could explain this morphology, in Your scientific article They propose to carry out more observations to determine why ‘Teleios’ is so different from other remnants. The identification of the conditions that have given rise to this cosmic object can help cosmologists to understand better What happens during the production of a Supernova and what parameters delimit the evolution of the remnant that will remain in space long after this great explosion occurs. In fact, these Australian astrophysicists have estimated that ‘Teleios’ is at a distance between 7,170 and 25,100 light years.

Reducing weight loss carbohydrates seemed a perfect plan. We have just discovered that it comes with unforeseen risks

Carbohydrates or carbohydrates are a fundamental macronutrient in our diet. They represent, together with the fats, the main energy contribution to our body. Carbohydrates are also protagonists in some diets destined for weight loss, diets based on the fact that, in the absence of these nutrients, our body will resort to the energy stored in their fatty tissue. A plan that is not infallible. DNA damage. A new study has found a mechanism that could link low carbohydrate diets with a Risk increase of suffering from colorectal cancer. The union link would be in the microorganisms that reside in our digestive system, our intestinal microbiome. In a study conducted with mice, the team responsible for the analysis observed that these types of diets could worsen the deterioration of DNA caused by some of the microbes that usually inhabit our digestive tract. This facilitates the appearance of polyps that in turn increase the risk of appearance of this type of tumors. “Colorectal cancer has always been seen as the consequence of a number of diverse factors, including diet, intestinal microbioma, environment and genetic,” explained in a press release Alberto Martin, co -author of the study. “Our question was, does the diet affect the ability of specific bacteria to cause cancer?” Three diets under study. In his study, the team tested three types of diet: a “normal”, a carbohydrates, and a “western” rich in fat and sugar. He did it by combining these diets with different types of usual bacteria between our intestinal microbiota and suspects of keeping some kind of relationship with the risk of colorectal cancer. They found a combination of diet and microorganism with potential to trigger adverse relationships, that of the low carbohydrate diet and a variety of bacteria of the species Escherichia coli (E. coli). They observed that this diet encouraged production by the bacterium of the colibactin, a compound with the ability to damage the DNA and with it of producing cancer. The key I could be in the fiberthe team points out. This type of diets facilitates inflammation, altering the microbial community of its interior, which in turn creates an ideal environment for the propagation of the E. coli. A fallen barrier. The team also observed that the mucous barrier that separates epithelia cells (the outermost cells of the intestine) of bacteria was reduced, which could also facilitate that colibactin reaches intestine cells. This would increase the harmful potential of the compound. The details of the study have been published In an article In the magazine Nature Microbiology. And what about humans? Studies with mice have an obvious limitation, and it is that extrapolating what is observed in these rodents to our own species is not always possible. The team He stood out for it The need to confirm their findings in people, although they were also optimistic about the possibility that their study could be applied in cancer prevention. The microbioma in the spotlight. This is not the only recent study that has put in the spotlight to the bacteria of the species E. coli already the colibactin in regards to colorectal cancer. A few days ago We had the news of A study Made with patients from 11 countries who found exposure tests at an early age to this toxin could be linked to an increased risk of these types of tumors.
