The Samsung Galaxy S25 Ultra drops into a store with an outlet price (and is not reconditioned)

by

When we look for a mobile we usually want the best for the lowest possible price, it is something that is met with the different offers offered by stores. He Samsung Galaxy S25 Ultra It is one of the best mobiles that have been launched in what we have been for a year and, although it has an official price of 1,459 euros, it is now in PowerPlanet per 999 euros. And much eye, because it is not a reconditioned mobile, it is totally new. In fact, in stores like Back Market, you can find reconditioned for a higher price. Samsung Galaxy S25 Ultra (256 GB) * Some price may have changed from the last review A high -end mobile with reconditioned price He Samsung Galaxy S25 Ultra It is a continuous mobile, but that has managed to hug some significant improvements especially in relation to design, processor and autonomy. Yes, it is a fairly large mobile that rides a 6.9 -inch panel, but it also has a very particular design and is much more comfortable to use than the Samsung Galaxy S24 Ultra. One of the biggest jumps we see in the processorthat for this generation Samsung has opted for Qualcomm Snapdragon 8 Elitethe most powerful we are seeing in the mobiles with Android. And to this we must add that it comes with 12 GB of RAM and with a base configuration of 256 GB of internal storage, which is what we can see of offer in PowerPlanet. The battery, although 5,000 mAh, offers an excellent autonomy with which it is almost impossible not to reach the end of the day. Of course, it is also compatible with Samsung Dexit comes with the integrated S-PEN and its photographic section stands out without a doubt for its main 200 MP sensor.

We are going to explain everything so that nothing caught you by surprise. News of Android Auto 14.8 This is one of those versions of Android Auto that have no visible improvements, therefore Do not expect to find new functions When you update your mobile and connect it to your car’s console. On this occasion, the only novelties are the solution of bugs and errors in the system, so everything should go somewhat better and with less failures. Also The performance of the infotainment app has been improvedso when seeing various content or playing with the stop car you should have greater fluidity, something that many users will appreciate However, none of the changes we know has yet arrived that Google is preparing. For example Gemini is expected to replace Google Assistantalthough we still do not know when this change will begin to unfold. It will be time to wait. We also know that working on a new change, although for now there is also no news about him. And why are there not usually more news and when there are them they are apparently small? Because The news of Android Auto van inside.

The US prepares to bomb the border of Mexico with sterile flies. It will not use genetic engineering, but 1950 technology

by

The United States wants to stop the Cochliomyia hominivorax, A fly that when it is in the larval phase causes a parasitic disease that mainly affects cattle (although it can also affect humans). A few days ago we talked about the plan to end her: launch millions of sterile flies to stop their expansion. The funny thing is that they are not going to do it using Genomic editionbut for this they will use a technology ago. X -rays and planes. The objective of this initiative is to stop the expansion of this plague and for this what they are going to do is sterilize millions of flies. As? With A technology that has been using since the 70s To combat this plague: X -rays. After raising the larvae and that they transform into pupae, they are placed inside a metal cylinder that is introduced into a gamma irradiation chamber with a dose of between 40 and 65 gray, enough to reach 95% sterility without compromising their survival. The container (left) that is introduced into the irradiation chamber (right). Fountain Once sterilized, you have to reach the affected areas, in this case the southern Texas and Mexico. To ensure that they arrive in the appropriate phase, the pupae remain at 10 degrees so that their metamorphosis to adults slows down. They are released from airplanes and, when the temperature rises, sterile males emerge. Why not transgenic flies? Sterilization of insects by radiation has decades of proven efficacy. Genetic modification is potentially cheaper and efficientbut it is still in an experimental phase and is not ready for mass production. There is also the issue of regulation, more complicated in this case because it requires approvals from two countries: the United States and Mexico. The current legal framework under which sterile insects are released does not contemplate genetic modification and achieve approval I could take years and cost millions of dollars. The threat. The one known as “Cattle Barrenter” is a devastating species, especially for cattle. The females deposit their eggs in wounds and mucous animals and, when hatching, the larvae begin to feed on the meat, causing injuries that become mortal. According to the head of the American Association of Veterinary Medicine, They can kill a 450 kilos cow in two weeks. This pest affects mainly to countries in South America, but It is not the first time that the United States has to deal with it; In 1966 they already eradicated it and in 2017 there was a small outbreak in the Florida Keys. There is a hurry. Although the reduction of transgenic technique costs sounds attractive, the reality is that there is no time to lose. The boreride worm has reappeared in southern Mexico and, although it has not been detected near the border, from the United States They don’t want to take risks. In addition to the release of sterile flies, other measures will also take controls in the transfer of animals, collaborate with Mexico to improve surveillance and provide traps to catch larvae.

The United Kingdom was waiting for an invincible hunt. Today, the F-35 flies little and cannot shoot its own weapons

by

He F-35b Lightning It is one of the most advanced fighters in the world. It has low observability when radar can take off in short distances and land vertically, and is designed to operate from Terrestrial Bases and Bases. You can execute Aire-Aire, air-surface, electronic warfare and intelligence in parallel missions. On paper, the United Kingdom was going to turn it into the cornerstone of its aerial power, With 138 planned units and a service horizon until 2069. But reality goes behind that ambition. A new report by the National Audit Office (NAO) He has just documented in detail a series of problems that drag the program: from sustained delays to capabilities yet to be integrated. The result is a much less solid photograph than expected a decade ago. And that opens uncomfortable questions about costs, efficacy and planning. F-35b, promises and delays As we said, the F-35B Lightning is the short take-off version and vertical landing of hunting by the United States The Joint Strike Fighter program. United Kingdom chose this variant To replace your Harrier and operate from the Queen Elizabeth class aircraft carriers. You can fly to more than Mach 1.6, reach 50,000 feet of altitude and execute multiple types of mission. A Harrier plane landing Its strong point is in the fusion of sensors and in the ability to share data in real time with other platforms. Unlike previous generations, the F-35B not only acts as an attack vector, but as a network intelligence node. In 2012 the first units arrived in the country, with Raf Marham as the main base. United Kingdom has invested at least 11,000 million pounds (about 12.6 billion euros) until March 2025, According to the National Audit Office. And yet, the level of operational capacity reached is lower than the ministry expected in 2013. The postponement of the total operational capacity (FOC) of 2023 at the end of 2025 implies that the F -35b have not yet reached the degree of maturity necessary to operate with full capacity. According to the NAO, the flight hours accumulated in 2024 were lower than those required, which limits the preparation of crews and the real availability of the fleet for intensive missions. In addition, the plane is currently limited in armament. Today only the guided pump Paveway IV and the Air-Aire Amraam AIM-13D, According to the RAF technical file. NAO confirms that the integration of British Meteor and Spear 3 missiles It has been postponed until the early 2030. In practice, this means that the F -35B cannot yet execute attacks from long distance with state -of -the -art weapons, such as its original strategic purpose. An F-35 landing There are also structural limitations. As The Register has pointed outthe short take -off design and vertical landing (Stovl) imposes significant restrictions on the payload and at the operational reach of the plane, something that conditions its effectiveness in demanding combat scenarios. This assessment is not part of the official NAO report, but it does reflect a usual concern among several specialists. To all this, the cost of full life cycle could reach 71,000 million pounds (about 81.9 billion euros). The problems are not alone Although the F-35B is already in operational use, the figures reveal a compromised capacity. In 2024, only around one third of the fleet was available to execute all the expected missions. Part of the problem is structural: the United Kingdom has failed to cover all the necessary positions to operate and maintain the system. Engineers are scarceand prolonged displays in aircraft carrier make many fate F-35 as unattractive. A F-35B of the United Kingdom The supply of pieces is not guaranteed either. The global logistics system, managed from the United States, has not grown at the same pace as the international fleet. That has generated bottlenecks, delays in deliveries and an excessive dependence on temporary solutions. Although during the deployment of Carrier Strike Group of 2025 the availability rates were improved, everything indicates that these levels may not be maintained once the operation is finished. Despite delays, costs and availability problems, the United Kingdom retains an outstanding role within the International F-35 program. He was the only level 1 partner to join the United States -led program and maintains 38 members of the Ministry of Defense Integrated in the central team of the project in Washington, more than any other country. This implication has given tangible results: British companies manufacture at least 15 % of the value of each unit produced. An eye on the future While the F-35 still faces limitations, the United Kingdom already promotes its own next generation project: The Tempest huntintegrated since December 2022 in the multinational program Global Combat Air Program (GCAP)together with Italy and Japan. Conceptual image of the future hunting of the Tempest program This effort, led by BAE Systems (United Kingdom), Leonardo (Italy) and Mitsubishi Heavy Industries (Japan), aims to develop a Sixth generation furtive plane for 2035with prototypes flying before 2028. The headquarters of the program is based in the United Kingdom. Since its origin, it has been raised as an open architecture platform, with engines, plane, sensors and weapons developed under national control, seeking greater technological autonomy with respect to the US. Despite optimism, there are still tensions. Italy has expressed concern about the lack of transparency in the technological transfer from the United Kingdom.

The first prohibitions to diesel cars over 10 years are already underway. There is only a small detail: there are no

by

Gasoline cars that comply with Euro 3 and diesel cars that comply with Euro 4 or Euro 5. That is the definition made by the DGT of the vehicles that They carry the bchatin B in cars. Although, really, what traffic has done has been discriminating for years of enrollment. Thus, cars with stickers B are enrolled between 2000 and 2006 for gasoline cars and Between 2006 and 2014 for diesel. This decision has generated some inconveniences since there are vehicles enrolled before 2000 (gasoline) or 2006 (diesel) that comply with the aforementioned emission regulations. But, except those exceptions that can be reviewedcars with stickers B are at least ten years behind them if we talk about diesel vehicles. Discrimination has raised some controversies since the owners of these cars face more hard restrictions than gasoline cars. To sticker equality, his car is many less years old. And that opens the door to be prohibited to diesel cars more modern than gasoline in our cities. Restrictions that, as you have been able to read, are already applied or will arrive very soon. But they do not exist. An exception (very exceptional) In recent days, social networks have been filled with messages that point to alleged prohibitions to cars with sticatin B. that is, gasoline with more than 19 years behind them but diesel with just over 10 years. But the truth is that when one goes to detail, those prohibitions They do not exist or, at most, they will be very soft restrictions that do not limit the use of the car. First, you have to understand that Since 2023 All cities with more than 50,000 inhabitants had to launch low emissions (ZBE) areas to improve air quality. But in the regulations It was not established how they should be These, who had to affect nor a punishment was established for not doing so. This has caused many municipalities to choose not to apply the measure, claiming that they needed clear orders from the government (aware that it is a measure that can negatively affect the electoral level). But it has also caused Paradoxes like Ciudad Realwhere you aspire to establish a ZBE … where all cars can access (even those who have no environmental labeling of the DGT). If we use the map that the government itself has active and select Restrictions by B labelwe will see that only the city of Segovia, Madrid and Barcelona remain active. In Madridcars with b label can circulate without problem but in the area of low emissions of special protection center center (ZBEDEP CENTER DISTRICT)they are obliged to park in a parking lot, whether public or private. It is the same restriction as when the area was called Madrid and there are no firm plans to change it. The case of Barcelona is a bit more special. Right now, all cars with stickers can circulate within the Metropolitan Area of Barcelona (AMB) without restrictions. Of course, cars with stickers B are included. The point is that The Generalitat of Catalonia has given green light to a plan to put obstacles to its use. That plan puts on the table restrictions on cars with B label from January 1, 2026 in all cities of More than 50,000 inhabitants within Catalonia as long as the anti -antamination scenarios are activated. That is, when the pollution is so high that it forces to prohibit circulation to some vehicles. It is something that It is also contemplated in Madrid In some scenarios. The protocol does contemplate the restriction of cars with B label B but as of January 1, 2028. By then, those cars will be over 14 years in the case of diesel and more than 22 years if we talk about gasoline. In Catalonia, cities with more than 50,000 inhabitants are Barcelona (and all the municipalities that already enter the AMB), Lleida, Tarragona or Girona, among others. You can consult here on this link. However, in the plan it is only specified that they will have to have a ZBE and that it must restrict the circulation to the cars with environmental label B but the size of it is not specified. That, just as it happens in the rest of the territory, has proliferated cities where Zbe barely affects a handful of streets, without substantial impact for the vast majority of drivers. That is what happens in Salamanca, the only city that Restrictions to cars with sticatin B already applies throughout Spain. However, the size is just 0.37 km2, the historical bud. Inside can access the aforementioned vehicles if they are registered in that area or if they do it outside the schedule established for the application of the ZBE: Monday to Thursday: from 7 a.m. to 8 p.m. Fridays, Saturdays and Vespers of festive: from 7 to 23 hours. Sundays and holidays: 10 to 20 hours. Much Runrún and few prohibitions In spite of everything, in some media we continue to read that there are already prohibitions raised to cars with almost immediate application B label, as inferred in the holders. Then we leave a list of the most commented cities and what will be applied or not. Bilbao: This zbe It has a size of 2 km2 and is active from Monday to Friday from 7:00 a.m. to 8:00 p.m. In that time section, from June 15, 2025 cars with B label B of the DGT are forced to enter a parking lot (as in Madrid) but can enter with that condition until January 1, 2030. By then, these diesel cars will have at least 16 years. Estepona: This zbe It has a size of 0.49 km2 and is also located in the historic center. Here, cars with stickers B are obliged to park in a parking lot or in a hotel, as in the previous case of Bilbao. There are no more restrictions. Getafe: This zbe It has a size of 1.18 km2. Since 2025 it has the same … Read more

We are champions in productivity with medium and large companies. The problem is that with SMEs we lose by win

The OECD data has been putting the red lantern to Spanish productivity decades. However, that perception does not Low productivity in Spain It does not fully adjust to the reality that reflect the Recent OECD reports. Such and as they highlight in The confidentialalthough the global data show a very discreet increase, companies of between 10 and 250 workers exceed productivity to the average of their peers in the OECD. However, the big problem is that 95.1% of Spanish business fabric is made up of SMEs with between 0 and 10 employees. What the OECD says about Spain. The OECD, in Your productivity report Of 2024, it evidences that the average annual growth of the hour per hour worked in Spain has been 0.5% per year, while the OECD as a whole has registered an average of 1.2%. That places the country clearly below the average of the Club of developed economies. Despite this scenario, a BBVA Foundation Analysis On the evolution of the total productivity of the factors (PTF), which combines the productivity of labor and capital to leave a photo closer to the reality of companies, says a growth of 0.9% interannual of this parameter. Which reinforces the conclusions of the OECD on the growth of productivity in Spain, which is like the Second country with greater growth of productivity in the last two decades. However, beyond the global data of Spain, the graphics of the OECD productivity study value the largest companies already medium -sized as a productivity engine in Spain. Thus, the OECD evidence that the mismatch in productivity is not so much between Spain and Europe as a whole, but among the different company sizes within the country itself. Total productivity of the factors (PTF) by country. Source: Productivity Council of Spain Microenterprises: many and unproductive. As recognized From the report From the Productivity Council in Spain, the most relevant feature of the Spanish productive fabric is that 95.1% of Spanish companies have less than ten employees, confirming that microenterprise is the standard in Spain, not the exception. According to the OECD dataSpanish microenterprises generated in 2023 an added value of $ 56,990 per worker, compared to $ 108,356 per employee generated by large companies. That means that large companies are 90% more productive than SMEs. The productivity of microenterprises is 15.3% below the OECD average and represents one of the main ballasts for the national average. He OECD diagnosis On microenterprises it is clear: having many very small companies limits the Productivity improvements and investment capacity. Medium companies approve with note. The highlight of the international comparative analysis is that, according to the OECD, “Spanish medium -sized companies have a productivity higher than the EU average, standing above the other advanced countries in their category.” In percentage terms, Spanish companies of 10 to 49 employees are 8.7% more productive than the OECD average; those of 50 to 250 employees 9.1% and those of more than 250 employees 5.2%. In other words, only 4.9% of companies in Spain would be above the OECD average, occupying avant -garde positions in terms of competitiveness in markets International The challenge: increase size and investment. The recipe that the OECD gives to Improve productivity Of these microenterprises it is clear, but it is not simple to apply: it is necessary to seek improvements in productivity through Investment and innovationimproving the value added by employee so that the business fabric gains size. According to 2023 dataSpain is at the tail in investment in machinery, ICT assets and i+d. Precisely, a Report of the Bank of Spain He pointed to productive investment as the key to business growth. The report emphasizes that private business investment had not managed to recover prepondondemic levels, while public investment in this area had recovered and grew at a good pace.

It is likely to cause you nightmares while sleeping

by

Lactose intolerance can take away the dream, and in a quite literal way: the stomach problems caused by the bad digestion of this protein can populate our nightmare dream, turning nighttime rest into an even more difficult challenge. Fuel for nightmares. A new study He has found A curious link between our diet and the quality of our dream. The analysis showed that healthier options correlated with more placid memories about lived dreams, while dairy consumption was related to nightmare memory. The explanation could be in lactose intolerance. This gastrointestinal reaction, explains the team responsible for the investigation, could be responsible for altering our dream causing these uneasy dreams. Bad matter. “The severity of nightmares is robustly associated with lactose intolerance and other food allergies,” explained in a press release Tore Nielsen, co -author of the study. “These new findings imply that changing eating habits in people with some food sensibilities could relieve nightmares. This could also explain why people often blame the dairy of their nightmares.” 1,082 students. More than a thousand students from the Macewan University, in Alberta, Canada, participated in the study. The participants responded to a survey in which he questioned his dream, time and quality of this, as well as dreams and nightmares. The questionnaire also consulted about the perception between dreams and food, as well as on the state of health, physiological and psychological of students and their relationship with food. The team observed that about a third of the sample replied to have had nightmares, this being more common among women. They also declared in the survey a better memory of their dreams and a worst quality of sleep. It was also observed that they were twice as much prone to declare food allergies as they. Cheese and nightmares. Analyzing the survey responses, the team observed that people with worse eating habits declared more frequently negative dreams, and tended to remember less their dreams in general, Explain the team. When studying intolerances, they observed that lactose intolerance was associated not only gastrointestinal symptoms but also nightmares and a poor sleep quality. The team therefore suggests the possibility of a relationship between the consumption of dairy, gastrointestinal problems and an discomfort that affects not only the quality of people’s sleep but also the “content” of their dreams. The details of the study were published In an article In the magazine Frontiers in Psychology. From the plate to the pillow. The relationship between our diet (especially the food we consume before we go to bed) and the quality of our dream It is well documented. However it is but little by little we are knowing New details that show us the complexities of this interaction. Knowing these details is what can help us understand what actions and what changes in habits can help us improve our quality of life, for example, facilitating a repair and pleasant dream. Maybe a step can be as simple as leaving cheese for snack. It is not perfect. The study also presents limitations, as you remember In an article for The conversation Timothy Hearn, from Anglia Ruskin University. Hearn, who was not involved in the study recalls that the sample is limited to young participants and generally in good psychological health. The nature of the study, in the form of a survey, also raises important limits, such as the so -called “memory bias”, which may arise if our ability to remember certain dreams correlates with any of the variables of interest.

Tiktok and Instagram have become an immense compilation of stolen videos. And they have no idea how to solve it

by

Open Tiktok (or your trusted short videos platform) and the following appears: a clip extracted from a podcast uploaded by random account @user97567, a video to a split screen with a talk up and Parkour in Minecraft below and a compilation of cat videos that upload @funnycatslolhaha. What do all these clips have in common? That none is proper. All that content It has been stolen to its original creators And the problem is that no platform seems to know how to solve it. Context. When you go up to the Internet, controlling its distribution is extremely complicated. In the same way that no one can prevent you from copying and hitting this text on a blog, preventing someone from downloading A YouTube video, A Tiktok, A reela content in general, it is not an easy thing. On many occasions the platform itself allows and, if not, it is possible to resort to third -party tools that sometimes can even remove the water brand. 21 Instagram tricks – Tutorial with all secrets! So that. Profiles that rectify content of other users do not do so for love of art. They do it with two possible objectives: monetize the account using dedicated platform funds or inflate the figures to sell them. Surely names Babronazi o PostureoEspañol make the bell sound. It is also possible that it is a fans account, in which case the reason may be more innocent. Be that as it may, these accounts are promoted based on stealing content from other users and republicing it after a slight modification (if any). The typical “for you”: Memes accounts, cat videos and accounts with zero units of own content | Captures: Xataka In fact, there are profiles and courses specialized in what is normally known as “network automation”. Roughlythis system consists of combining AI tools, videos of other creators and fast editing templates to generate a huge volume of videos and monetize the account. It is one of those practices to “generate passive income“, among quotes, how strong they usually hit in a certain segment of the population. The reality, however, is much more complex. Solutions. Few, unfortunately. Some users have found to embed a water mark within the video itself a way that, if any discharge tool can eliminate what generates the platform, that remains. However, the reality is that social platforms have failed to stop the distribution of original content by third parties. Facebook, Instagram, YouTube and Tiktok are full of that content. The algorithm mixes it with the original content and serves it to users, which consume it. To all purposes, the platform is gaining because its objective (increase retention) is achieved. The creator, although it can be relatively benefited in terms of exposure, loses the gain that, potentially, could have had his profile of having published said content. Image | Xataka What are platforms doing. Given this situation, some platforms have tried to take measures with greater or lesser success. YouTube has it well tied. Although it is possible to continue up and monetizing “reused content”, that is, the typical video reacting to the new song of X or the video of another creator, the platform does not allow monetizing what it considers “non -authentic content” (mass made videos) or clips extracted from a podcast that is not yours. This applies to both long videos and shorts. Instagram allows Upstate third parties and does not hit. Now, if you detect that someone has uploaded a video of another person, you will automatically add an “original content of” content and link it to your profile. Politics, however, is … complex. The material edited materially, see “a person appears in a superimposed video and adds new information, such as comments”, is allowed and distributed as normally. Facebook has been more permissive (to the point of allowing direct monetization of videos with non -original content), so far. THE META PLATFORM has announced which will adopt in its reels a policy similar to that of Instagram. However, there are no mechanisms to prevent a reused content page. Tiktok It has some guides That, on paper, they exclude from ‘for you’ the “reproduced or non -original content that does not incorporate new or creative changes.” The reality, however, is that it is enough to add subtitles or make some edition for the video to be distributed as normally. Another issue is intellectual property. This is a swampy terrain and the platforms usually cover their backs in their policies prohibiting it, directly. When we upload a video to Tiktok or Instagram we grant a global license so that this video is exploited, but the rights of said video remain ours. We could, in theory, put a copy of Copyright to all the accounts that we see to use our content, but that is an intense job and, speaking in silver, putting doors to the field. We can find the same in other sectors. For example, models uploaded to 3D printing repositories are, unless it is marked, for personal use. That a Makerworld model is downloaded has no commercial license to exploit it in your Etsy store. However, this a practice known and persecuted by the community, but against which it is difficult to fight. In summary. The accounts that use third parties will not disappear and combat this practice does not seem easy. That is a full -fledged paradox, since the platforms encourage users to raise original content, but at the same time they do not protect it completely. And not only that, but the user does not care in excess because, after all, they go to these platforms to entertain themselves. It is indifferent if that entertainment comes from the most worked video in the world, a compilation of funny babies, the Senimous Iteration of Tung Tung Tung Sahur or a video of a boy dancing on a kayak.

The artificial skin that feels heat and cuts is already real. It is the first big step for robots to look more like us

by

Can a robotic hand like that of Optimus or that of 1x get to feel like ours? Researchers at the University of Cambridge and the University College London believe they have taken an important step in that direction. They have developed one Artificial skin Composed of a single flexible material, capable of detecting temperature, pressure, cuts and multiple simultaneous touches. All without rigid layers or sensors distributed inside. And the most promising, according to its creators, is that it can adapt to complex forms and promises a relatively simple manufacturing process: it is enough to melt it, pour it into a silicone mold, remove the internal positive and place it as a glove on a robotic structure, as shown in This demonstrative video. The nucleus of this technology is a driver hydrogel that, when combined with electric impedance (EIT) tomography, allows you to continuously register what happens on its surface. When a stimulus occurs – contract, heat or pressure – the fields are altered. The system detects not only the type of stimulus, but also its location and environmental conditions. All this is interpreted through automatic learning, with latencies that depend on the number of active channels, explain in the article published in Science Robotics. A soft membrane, millions of data The best example of the system is a robotic hand of real size, hollow inside, fully covered with this artificial skin. Instead of distributed sensors, use exclusively 32 electrodes placed on the wrist. This configuration was sufficient to extract more than 1.7 million information channels, derived from 863,040 different combinations. During the tests, the hand was exposed to different stimuli: a human finger, a thermal probe, the impact of a scalpel. In all cases it was able to distinguish the type of interaction and locate it with an average precision of about 25 millimeters above its entire surface. The interesting thing is that a sensor is not necessary for each type of stimulus. The membrane itself reacts differently depending on the intensity or nature of the contact, and it is the model of the one that identifies the most relevant signal between hundreds of thousands of possibilities. In addition to touch, this skin is able to monitor the environment. During a 100 -hour test, the system registered variations between 19 and 25 ° C and between 38 and 72% relative humidity, as details The official note of the University of Cambridge. All this with a design without rigid components, which facilitates its integration into Prosthesis, technical clothing, control surfaces or collaborative robots. Applications ranging from rehabilitation and remote exploration to the automobile sector. Of course, this development does not start from zero. In recent years we have seen other proposals that seek to endow robot sensitivity, such as This synthetic skin capable of replicating pain, This other that presumes to approach human skin as never beforeeither A capable of self -backing and recycling. What distinguishes the work of Cambridge and UCL is its radically simplified approach: a single flexible layer, without mechanical components, which centralizes all sensitivity and interprets it by software. Challenges remain in front: improve the resolution in areas far from the electrodes, reinforce the resistance of the long -term hydrogel. But paradigm shift seems to be underway. Everything indicates that it is a matter of time until we see robots not only more advanced in mobility and interaction, but also closer to us in appearance and physical sensitivity. An artificial skin like this opens the door to a new generation of machines that not only execute tasks, but also “feel” the surrounding environment. Even so, we are far from reaching the level of realism that proposes’Detroit: Become Human‘. Images | Cambridge University (1, 2, 3) | Quantic Dream In Xataka | Figure 02 has worked only for an hour.

We know exactly where and when the longest solar eclipse will occur in history: our great -great grandchildren will see it

by

On July 16, 2186, the Moon will align perfectly between Earth and the Sun, creating an unprecedented eclipse. Unless Millionaire eccentric determined to rejuvenate Be successful, none of us will be here to see it. But our descendants will want to spend that day somewhere in Colombia, Venezuela or Guyana. 7 minutes and 29 seconds. The longest total solar eclipse in history will exceed in almost two seconds the duration of the record until now: the eclipse of June 15 of the year 743 AC, which reached a totality of 7 minutes and 27 seconds on the Indian Ocean, near the current Kenya and Somalia. No eclipse will have lasted so much From before 4000 ACand none will do it until after 8000 AD, so we can be sure that it will be a really unique astronomical event. The total solar eclipse of longer duration in an interval of 12,000 years. The moon will obscure South America. The historical solar eclipse of 7 minutes and 29 seconds will not occur on the mainland: the strip of totality will reach its largest duration over the Atlantic Ocean. However, northern South America will also enjoy extraordinarily long totalities. Especially in Colombia (from Cali to Puerto Ayacucho), Venezuela (from the Orinoco to Imataca) and Guyana (throughout the northern half of the country, including Georgetown). The show will not be limited to that narrow strip. Virtually all South America, including the entire Brazilian territory, can observe a partial eclipse of great magnitude. The eclipse will also be partially visible from Mexico to Paraguay, and west of Africa. In Spain, the Canary Islands will barely touch at sunset. Why it will last so long. The reason for this extreme duration is a “perfect storm” in the positions of the three bodies. The Earth will be at its point farther from the sun (its aphelium), which will make the solar disk look slightly smaller. The Moon, meanwhile, will be at its closest point to Earth (its perigee), so its apparent album will be larger. And finally, the eclipse trajectory will pass very close to Ecuador Earth. This combination maximizes the time that the shadow of the moon takes to sweep the surface of the earth. How we are so sure. Eclipses’ prediction is one of the most successful feats of computational astronomy. The scientists feed their superorders with the current positions and speeds of the Earth and the Moon, and then use Newton’s Movement Laws to know what will happen within several centuries or even millennia. These algorithms are actually models that integrate gravitational equations to project their positions in the future. And they do it with amazing precision, usually with a margin of error of less than one minute over hundreds of years. Primo brother of a recent eclipse. The total solar eclipse of 2186 belongs to the same “lineage” as the great eclipse of North America of April 8, 2024, The Saros 139 cycle. A cycle of Saros is a period of approximately 18 years, 11 days and 8 hours, after which the Sol-Tierra-Luna geometry is repeated almost identically, producing a very similar eclipse but displaced about 120 degrees to the west. The discussions among the eclipses enthusiasts already fantasize about how the hunting of this event will be in 2186. There is talk of flotles of cruises positioned in the Atlantic and flights in hypersonic airplanes to pursue the shadow and further extend the experience of totality. Although we can only imagine it, it is a fascinating reminder of how science allows us to travel in time and be witnesses, at least on paper, of the wonders that the cosmos reserve for future generations.
