The big problem with putting robots everywhere is that they get lost. An engineer from Elche believes she has the solution

by

It is no surprise that we see more and more robots in our daily lives: in a restaurant bringing orders to the table, in the field as a seasonal workermaking him courier delivery competition…and that’s not to mention its applications in automation on an industrial scale. Robots don’t need to rest, they don’t have labor rights, and they don’t complain. But they get lost. And that is a real, very common problem for which a research team from the Miguel Hernández University of Elche has found solution. The context. Autonomous robots need to know where they are to function and that does not always happen: when the location reference is lost, either because someone moves it, it is turned off or the environment changes without warning, the robot is unable to recover its position. Something as normal as running out of battery can be a technical drama. This phenomenon is not something isolated, in fact it even has a name in robotics: the “kidnapped robot problem“. Although we see more and more robots everywhere, this incident is a pending issue that has not been resolved in a robust way for decades. Without going any further, because resorting to GPS is something that can fail in settings such as indoors or near tall buildings. As deepens Míriam Máximolead author of the article: “It is a classic problem and very difficult to solve, especially in large environments.” The solution. What the team from the University of Elche has implemented is MCL-DLF, the acronym for Monte Carlo Localization – Deep Local Feature, a system that combines two technologies: on the one hand, a 3D LiDAR that emits laser pulses to draw a three-dimensional map of the environment similar to that of robot vacuum cleaners. On the other hand, an artificial intelligence that learns which elements of the environment are most useful for orientation. Why is it important. Because having a reliable location system is essential for any robotic deployment in real life: autonomous vehicles, delivery and logistics, assistance… its presence may be increasingly common, but it is still tremendously dependent on supervision: knowing where it is is essential for it to operate safely. The implemented method also introduces an important change: it is independent, in that it does not require external infrastructure to function like GPS, so its base is more robust and versatile in the face of different use scenarios in the real world. How it works. Its approach is hierarchical, so it first recognizes large structures and then fine details, similar to how people do. When you arrive at an unknown place, first you keep the essentials: what neighborhood you are in, for example. Then you look for more specific references to refine further. Furthermore, the system does not play everything on one card: it maintains several position hypotheses simultaneously and discards or refines them as the sensor captures more information. Tests carried out for months on the university campus with different lighting conditions, vegetation or simply the weather have shown more consistency than conventional methods. A good start with pending subjects. Beyond its promising results, the most striking thing about this research is its commitment to sensory autonomy: it does not depend on networks of beacons or GPS, but on its own sensors. This makes it a potentially more versatile system. However, it faces the great historical challenge of robot placement: how fragile it is in the face of changing environments. It is true that they have tested it in different conditions, but it has been within the campus: making the leap to more complex and constantly changing environments is their litmus test, in addition to additional validation in extreme conditions. Finally, before an eventual real commercial deployment, we will have to see how it integrates with other navigation systems and its computational cost.

MicroLED promises to be the Holy Grail of televisions. That is your big problem today.

by

There are technologies that are born with enormous promise. He MicroLED is one of them. Since Samsung introduced “The Wall” at CES 2018the sector has been telling us for years that this technology is going to revolutionize the way we watch television. And he is right. The problem is that this revolution has not reached anyone’s living room. who is not a billionaire. The technology has become the Holy Grail of the television industry, but the enormous cost of its manufacture means that only the most exclusive models and, let’s say it without frills, extremely expensive, can integrate this technology. Unlike what has happened with OLED or MiniLED, manufacturers have not managed to reduce production costs of these panels to make them competitive in mass manufacturing. What is MicroLED and why is it so special? To understand MicroLED you have to know how current screens work. Traditional LED TVs have a layer of pixels that filters light coming from an array of LED lights installed on the back. It is, therefore, a backlighting technology that offers very good brightness power. The problem is that when those screens need to display pure black, the screen can’t turn off pixel by pixel, so it turns off areas of those rear LEDs. The more dimming zones you have, the better the light control and the more control over the blacks you have. Even so, it is inevitable that some light will sneak in. It’s not really black. The result is very dark grays at best. The technology OLED solved that problem years ago, making each pixel on the screen emit its own light that can be turned off individually. Here, the result is a perfect contrast, but it has its own limits. The LED diodes that make up each pixel are organic, so they degrade over time and are susceptible to burn-in, leaving a permanent mark on the screen after many hours with a static image on the screen. In this sense, the promise of MicroLED technology is to provide the perfect balance between OLED and LED, but without any of their drawbacks. Like OLED, it uses microscopic LEDs as a pixel, but made with inorganic materials that are much more stable and resistant to burning. In this way, the screens MicroLEDs are capable of reaching OLED contrast levelsbut with a much higher shine and with a useful life that is measured in decades. It is literally the best of all worlds. And there is also its trap. The problem: manufacturing the MicroLED is a nightmare A 4K display has about 8.3 million pixels. In the latest MicroLED panels, each of those pixels needs three individual LEDs, leaving us with almost 25 million microscopic chips that must be manufactured, placed and connected with nanometric precision on a panel the size of a television screen. This level of miniaturization required by MicroLED has limited its production to large-inch formats before the challenge it poses fit so many millions of diodes into a 55″ or 65″ panel. The process of mass transfer of these chips, what the industry calls mass transferis extraordinarily complex, and today, also extraordinarily expensive. How much expensive? To put it in context, one of the few MicroLED models that can be purchased in stores is a 89 inch Samsung and has a sale price of 109,000 euros. He LG Magnitaimed at the extreme luxury market, was around 230,000 euros in sizes of 118 and 136 inches. That price range makes them unviable as home televisions (at least for most mortals’ homes). Hence its market figures are very small at present. In all of 2024, they were manufactured less than 1,000 units of MicroLED televisions in the entire world. Samsung sells that many conventional televisions in a matter of minutes. However, although these panels do not reach the living rooms, it does not mean that the MicroLED is stagnant. In fact, it is in development. This technology is growing strongly in those niches where price matters less than performance. In large format signage it has been the standard for years. film and television studio fundslobbies of luxury buildings or private movie theaters. In automotive, the dashboards of the future want bright, durable and efficient screens. And in the wearables segment and augmented reality, both Apple and Samsung have been investing for some time in bringing MicroLED to smart watches and AR glasses, where extreme pixel density is critical and having smaller production volumes makes the cost more manageable. As indicated in an analysis According to Yole Group, the global MicroLED market could grow to nearly $5 billion in revenue by 2032, although most of that will come from those niche segments, not the living room TV. There are MicroLED and “MicroLED” The high production cost made manufacturers explore other ways to make this technology profitable and evolve. One of the solutions was to use as backlight system behind an LCD panel, rather than as self-emissive pixels. Strictly speaking, although the latter have MicroLED technology, they should not be considered as such. However, some brands use it interchangeably in their trade names for advertising purposes. By having a smaller scale, MicroLEDs allow much better control of light and enhancing the colors, but they still require an LCD panel that separates the colors of each subpixel. That is, it would act more like a MiniLED or a conventional LED than an OLED. The good news is that, as brands showed like Hisense and Samsung have already evolved MicroLED technology with white diodes, towards the RGB MicroLEDwhich already has a self-emissive RGB diode for each pixel that, now, would be closer to the operation of an OLED. This evolution, as before MicroLEDs they made other technologiesrepresents the first sign that these panels are beginning a path of optimization to reduce production costs. In fact, the models launched by Samsung during the last CES 2026 It would be around $30,000.. It seems like an exorbitant figure for a television, but it must be taken into … Read more

their biggest problem is us

by

Of all the places in the world, the Limonium estevei “chose” a very specific place to live, evolve and develop: a beach in the municipality of Mojácar, in the southeastern end of the peninsula. What the poor thing didn’t know is that it was a bad place to survive. Scientists, however, have known this for a long time. Although they were wrong. The “Mojácar immortelle” is an ultra-endemism of the Mediterranean coast of Almería and, therefore, experts have feared for years that hybridization would wipe it out. But, all those years, the immortelle has held up. Now, a study from the University of Almería published in ‘Biodiversity and Conservation’ has discovered that, although there are hybrids with the L. cossonianumthe risk of this erasing the genetic identity of the species does not exist. Your problem is another. Location, location, location. The problem, as researchers have discovered, is that its persistence depends on preserving its edaphic niche. That is to say, it only grows in deliriously specific soils and if those soils disappear, the immortelle has a very difficult time. This would only be a problem if, by chance, the coastline were in danger. Because Limonium estevei It is a textbook species at risk: a single fragmented population highly dependent on its ecological niche that has no margin for survival in the face of changes in the ecosystem. And that ecosystem, unfortunately, has enormous tourist potential: Macenas, the beach in question, is in the spotlight of the construction companies in that area of ​​the country. It’s a matter of time before it fills up with people. The great paradox of the Spanish coast. Although one of its main heritages is bioecological, the Spanish coast is a terrain with strong incentives to self-destruct. The Algarrobico It’s just a few meters away. In other words, what researchers have discovered is that yes, the culprit is tourism: a model that is based on residential use and the construction of recreational infrastructure on the beachfront. And we do not have clear tools to stop it. The immortelle is, like so many others, an example of everything that fails in the system. And what is worse, of everything that we cannot solve.

In the middle of Valentine’s week, strawberries have reached figures never seen before in half of Europe. The problem is not love, it is Spain

by

Hearts, chocolate, bouquets of flowers and pink decorations everywhere: Valentine’s week is synonymous with many things, but above all with crazy prices. What was not expected in half of Europe is that strawberries were going to rise so much. And when I say ‘so much’, it’s ‘so much’. What happened to the strawberries? The peak in demand is predictable: every year, coinciding with Valentine’s week, the demand for strawberries skyrockets. And, furthermore, it is a very inelastic demand: since it is a “special” day, people continue buying them “almost” independently of the price. That has not changed in 2026: what has changed is that the supply has suffered a huge shock. A shock called Spain and Portugal: And more specifically its meteorology. If the frosts of a few years ago caused the shortage of red peppers throughout the European continentthe historic rainfall in recent months has reduced strawberry production, its quality and shelf life to almost historic lows. To give us an idea of ​​the collapse: in Huelva, production has fallen by half compared to 2025. And despite efforts to catch up, production is 38% below from that of the 24/25 campaign. This has meant that strawberries are arriving in the Netherlands at 5.83 per kilo and in France at 6.44. The problem naked. In this case, the problem is that Europe depends completely on Huelva and, in recent decades, it has not been able to do anything to avoid it. Huelva producers have demonstrated an impressive capacity to produce with very high quality at very low prices. That (and the constant rise in production) has meant that no one can build a parallel agribusiness. The problem is that the climate becomes increasingly volatile, the ‘security’ of the Andalusian countryside decreases. and this episode has only confirmed it. What’s behind the story. So what is hidden behind the strawberries at seven euros per kilo in a market in Alicante is the story of the loss of hegemony of one of the most solid and refined economic pillars in southern Europe. That is to say, while strawberries are on their way to becoming an ‘ultra-luxury’ product, Andalusia’s competitive advantage is fading. Are a giant with feet of clay.

Spain’s main problem is not weapons, fighters or drones. It is the number of hands you need to use them.

by

In recent years, the defense debate in Europe has revolved almost exclusively around money and technology. It talks about percentages of GDPmodernization and new systems capable of changing the battlefield. However, there is a much less visible factor that ends up being decisive when it comes time to turn plans into reality. A decade of losing muscle. The news Europa Press gave it. Since 2010, the Spanish Armed Forces They have lost 13,300 troops and they carry a structural deficit that the Military Life Observatory describes as chronic. As of January 1, 2025 there were 116,739 soldiers in active service, very far from the legal minimum of 130,000 established by the Military Career Law. The gap ranges between 13,000 and 23,000 uniformed personnel, a figure that is practically equivalent to an entire army within the system itself. Objectives that are not met. Several weeks ago another news item put the target on an enlightening fact: the regulatory framework establishes a maximum of 50,000 officers and non-commissioned officers, but there are only 40,656 dashboardsincluding 227 generals, leaving a wide margin unfilled. In the troops and Navy, the budget ceiling has limited staff numbers to 79,000 for years, although it is barely exceed 76,000 troops. The distance between what is provided for in the law and what is available in the barracks is not temporary, but sustained over time. More budget on weapons, fewer hands to operate them. The strategic debate in Europe has turned towards the modernization of systems and increased spending up to 2.1% of GDPbut the emphasis has not been transferred with the same intensity to the staff. Weapons programs and technological capabilities are expanding, but the number of military personnel is barely growing or even go back. Hence all this leads us to another reality very different from what we usually think: Spain’s main problem is not fighters, drones or new systems, but rather the great number of staff missing to use them and keep them operational. A 2025 that closed in negative. Despite the government’s commitment to increase staff by 7,500 personnel in four years, 2025 ended with 832 fewer soldiers than the previous year. The drop was especially pronounced at the officer level, where a thousand professionals they abandoned or passed to the reserve without sufficient replacement. Although non-commissioned officers and troops registered slight increases, the global balance was once again negative at a time when the international environment demands just the opposite. Lack of interest. The interpretation of these data leaves little room for doubt. The number of places offered has increased, but the proportion of applicants per vacancy has decreased worryingly. In the troop area the ratio has fallen to 4.2 applicants per placefar from the levels of a decade ago. In officers and non-commissioned officers, the descent is even more pronouncedwith fewer candidates and a worse selection margin, which limits the quality of replacement and anticipates problems of generational change. Salaries, mobility and little incentive for promotion. There is much more, as the report points to lower salaries to other bodies of the State and to an accumulated loss of purchasing power that discourages a military career. Constant mobility can imply a higher cost of living and low salary compensationleading many to give up promotions. The result is that “little interest” in progressing within the institution and a structure that ages without sufficient renewal. Stressed and aged. The other elephant in the room: more than a third of the dashboards exceeds 50 years and the troops also show progressive aging, while the reservists have decreased steadily since 2014. For its part, female participation grows slightly up to 13.1%above the NATO average, but it does not compensate for the overall loss of troops. I remembered the newspaper El Mundo that the system is also facing an increase in harassment complaints that adds reputational pressure at a time of low recruitment. Material capacity without critical mass. All this leaves a more or less illuminating map. Spain is investing in capabilities and is committed to increasingly demanding international missions, but it does so with less staff that fifteen years ago. The organizational structures and operational commitments have not diminished, rather the oppositewhile the human base it doesn’t stop shrinking. From that perspective, everything indicates that, if the trend is not reversed, the country may find itself with a future where the Armed Forces are modernized in equipment, but without the critical mass necessary to sustain them over time and respond reliably to an increasingly demanding strategic environment.

China is building submarines faster than anyone else. And that’s a problem for the United States.

by

In a tense geopolitical moment on a global scale with several open fronts such as Greenland, whose melting ice is allowing us to see nuclear submarinesChina just achieved a historic milestone: it is manufacturing nuclear submarines faster than any other country in the world, according to a report by the International Institute for Strategic Studies. This is a complete surprise to the United States, the power that until now held this title, and threatens the advantage that Washington has maintained for decades. Brief notes on nuclear submarines. Without wanting to delve into their characteristics, it is worth distinguishing what types there are: He SSBN is a nuclear-powered submarine designed to launch ballistic missiles with nuclear warheads (some with intercontinental range). They are strategic second response platforms, practically undetectable and guarantee that if someone attacks first, they will receive a response. The SSN/SSGN are nuclear attack submarines (the second, guided missiles), true maritime control weapons: they can attack land or sea targets, block routes and operate for months without resupply. Context. American hegemony underwater lasts for decades, but Beijing has on its roadmap modernize its military capabilities by 2035: it already has the largest surface fleet in the world in the words of the Pentagon and now he has turned on the turbo to reach the last bastion of the United States: the depths. The data. China has surpassed the United States in the pace of launching nuclear-powered submarines (SSN/SSBN). Thus, between 2021 and 2025, the Asian giant launched 10 units compared to Washington’s seven, according to has discovered the IISS through satellite analysis of the Bohai shipyard in Huludao (northern China), as the epicenter of the industrial leap. In a decade, China has gone from being far behind to leading the race: Why is it important. This shift in underwater hegemony has three implications, one of which points directly to the US: Nuclear deterrence. The new submarines Type 094 and future Type 096 They expand China’s nuclear response capacity in the face of possible nuclear attacks. A preemptive attack is strategically unfeasible. Maritime control of commercial routes. SSGNs with high-speed missile systems add a layer of threat to foreign combat groups in the Indo-Pacific, complicating access for the US and its allies to potentially conflictive areas, such as the South China Sea or Taiwan. At a time when The United States is betting on boarding As a sign of maritime control, China has in this fleet a safeguard for its commercial routes. The United States cannot cope with that pace. John Phelan, US Secretary of the Navy, recognized in Congress that “All of our programs are a disaster, honestly. Our best-performing program is six months behind schedule and 57% over budget.” Phelan mentions the erosion of this industry, which according to the Government Accountability Office Today it faces problems such as aging infrastructure and a shortage of qualified labor. The surprise figures. The IISS Military Balance 2025 leaves other interesting figures to better diagnose the reality of both powers in nuclear submarines: Launch rate from 2021 to 2025: seven from the US to 10 from China. The difference in tonnage is notable: while those from China weigh 79,000 tons, those from the US are 55,500. Active nuclear fleet: The United States wins by a landslide, with 65 units compared to China’s 12 units (plus another 46 conventional ones). Quantity vs quality. We have already seen in the previous point that the United States continues to gain in numbers (still) and it is not the only reason for optimism for the country led by Trump. CNN echoes the IISS report where he explains that “Chinese designs are almost certainly behind American and European submarines in terms of quality.” Among other qualities, in noise: Chinese submarines are noisier, which makes them more vulnerable, they explain.

The problem is that, until now, Korean brands ignored 90% of the planet

by

A South Korean cosmetics brand was recently forced to apologize after promoting one of its blushes by describing the shade as the “adorable cheeks of a Mongolian baby.” Controversy broke out when content creator Khaliun reported on Instagramin a video that surpassed 270,000 views, that the brand was exploiting an outdated stereotype. Faced with global pressure, the company modified the text for “a beautiful deep mocha pink color that appears gently warmed by the sun.” This incident is not an isolated anecdote. It is the reflection of an industry that exports its products to the entire planet, but that has historically designed its cosmetics with a single demographic in mind, systematically excluding most of the world’s population. The Western fascination with Korean beauty began in the 2010s. This first wave of K-Beauty focused almost exclusively in skin careexporting concepts such as double cleansing or the coveted “glass skin”. As these were facial routines, inclusion was not an obvious challenge. In parallel, K-pop and K-dramas became the perfect vehicle for soft power. “The visibility of K-pop and K-dramas reinforces the perception of the effectiveness of K-beauty,” explains Professor Hye Jin Lee to cnn. The consequence was immediate: in 2024, South Korea surpassed France as the main exporter of cosmetics to the United States, with 1.7 billion dollars in shipments. The problem arose with the arrival of the second wavewhen the trend expanded into color cosmetics and hybrid makeup. Traditionally, Korean brands They launched their makeup bases in just three to five extremely pale shades, baptized with names such as “porcelain”, “ivory” or “sand”, designed for its domestic market. When making the international leap, darker-skinned consumers found themselves facing a wall: the most innovative industry of the moment, simply, I didn’t make products for them.. The standard that excludes without shouting The K-pop industry has been celebrated for challenging gender norms — male idols wearing makeup or traditionally feminine clothing — but it has not been as racially disruptive. The dominant standards They continue to emphasize light skin, a small V-shaped face, big eyes, and a slim body. A recent academic article, published by International Journal of Social Humanity & Management Research, defines these standards as a form of cultural racism: not an explicit discrimination, but a symbolic system that presents an aesthetic as natural and universal while excluding other corporalities. The mechanism does not need to proclaim “we don’t want dark skin.” It is enough to define beauty as something incompatible with them. In the Asian context, the preference for light skin has historical roots linked to social status and neo-Confucian traditions where whiteness symbolized respect for its principles. This is summed up in the Chinese term bai fu mei (white, rich, beautiful), which is still commonly used to describe a perfect woman. But when that standard becomes a global consumer product, the reading changes. The globalization of K-Beauty has caused cultural clashes evident. On YouTube, the video series “Black Girl Tries Korean Makeup” made the frustration visible of black creators in the face of the lack of dark tones and the omnipresence of whitening products, pointing out a bias of “anti-blackness”. In response, part of the Korean audience defended the brands by arguing that Korea is a monoethnic country and that its standards should not be judged by “the western prism”. another study by researcher Andrea Gómez shows how “Asian beauty” is associated in Latin America with youth, health and clear skin. The concept of whiteness is not just chromatic: it implies status, modernity and privilege. In their interviews, salespeople and makeup artists acknowledged that many clients requested shades lighter than their real skin. Not necessarily to look Korean, but to get closer to an ideal historically linked to social advancement imposed since colonial times. This is where K-beauty fits in as the perfect piece: it sells scientific innovation and, at the same time, reinforces an aspiration for clarity and neatness that was already established. As Vogue Business points outthe global beauty industry “thrives on insecurity and the allure of attainable ‘improvements’ that privilege white skin.” And in many cultures, light skin continues to function as symbolic capital. A deep or strategic inclusion? The real change came when diversity was shown to be enormously profitable. The most representative case is that of the brand THROW. When African-American YouTuber Miss Darcei tried her popular foundation in cushion On social networks, she showed that the initial offer of extremely pale tones left her out. The brand responded by creating new ringtones and sending them to him; In a matter of months they expanded their range to 40 colors. The result of listening to a diverse audience was an astonishing increase in 55.465% in brand sales in the United States. Since then, other brands they have reacted. Dear Dahlia expanded the shade range of its liquid blushes and foundations to reach deeper complexions. K-Brown was born in Seoul focused exclusively on the care of melanin-rich skin. Yepo Beauty launched foundations designed for darker tones under the tagline “inclusive K-beauty.” In addition, corporate discourse also changes. Global giants like Unilever and L’Oréal they have already announced the elimination of explicit references to “whitening” or lightening of the skin on its packaging in the face of international criticism. But not all adjustment is virtuous. When the Youthforia brand released a tone 600 Described by critics as a pure black with no undertones resembling human skin, the product caused a stir and was discontinued. A poorly executed inclusion can quickly become a caricature. The tyranny of beauty The racial and aesthetic debate intersects with another axis of oppression: the obsession with eternal youth. The global popularity of collagen—in powder, cream or capsule—reflects growing anxiety and pressure not to age. This is despite experts such as Dr Afshin Mosahebi questioning the scientific soundness of many of these ambitious anti-aging promises. This demand to stop time falls disproportionately on women. Psychology Today remember that the standards of whiteness and bodily perfection present in K-Culture They are not … Read more

A new “solar system” has just been discovered. There’s just one problem: it shouldn’t exist.

by

Observations from NASA and the European Space Agency telescopes have made possible the discovery of a new exoplanetary system 116 light years from Earth. According to research by an international team led by the University of Warwick published in the journal Sciencethis new “solar system” has a peculiarity: its architecture contradicts the standard model of planetary formation. In short, based on the astrophysics we know, it should not exist. We do not know if it will force us to rewrite current theories, but we do know that we will urgently review them. The discovery. The LHS 1903 system is made up of four planets orbiting a red dwarf, the most common and longest-lived type of star in the universe. The question is how they are arranged: the innermost planet is rocky, the next two are gaseous and surprisingly, the outermost planet (LHS 1903 e) is also rocky. That planet shouldn’t be there. LHS 1903 e It is a large super-Earth (it has 1.7 times the radius of the Earth and 5.79 Earth masses, thus achieving a similar density) located on the periphery, but of course, it should not be in that position, according to current models. It is not a minor anomaly: it breaks the paradigm from the foundations. This provision contradicts the usual pattern that we see in all known planetary systems: the rocky planets (refractory materials) are in the hot zone and the gas giants in the outer cold zone, beyond the “snow line“, where ice makes it possible to grow large nuclei that capture hydrogen. The canonical example is our solar system: the rocky Mercury, Venus, Earth and Mars orbit closer and the gaseous Jupiter, Saturn, Uranus and Neptune orbit further away. Why is it important. According to theory, a planet as large as LHS 1903 e in that cold zone should have devoured gas until it became a giant like Jupiter. But there is another reading: that the formation model fails and is not the only recipe that explains how exoplanetary systems form. But as we mentioned above, red dwarfs are the most abundant stars in the galaxy and if the model fails in this system, it is plausible that it will not hit the mark in much of the cosmos either. There may be other “inverted” systems pending interpretation or that we have misinterpreted. A possible explanation. What the research team proposes is the gas-poor formation mechanism hypothesis. In short, the important thing is not so much where but when. Thus, the planets were formed one after another in the opposite order to our solar system, starting first with the innermost one and going outwards from there. When planets form, they consume the gas available in the disk that surrounds the star. LHS 1903 was formed last, when there was no more gas left, so it could no longer become the gas giant that might have been expected. As explains Lead researcher and University of Warwick professor Thomas Wilson: “It means that the outermost planet formed millions of years after the innermost one. And because it formed later, there really wasn’t enough gas and dust left in the disk to build this planet.” The research method. The data analyzed by the international team comes from the collaboration of NASA’s TESS telescopes and ESA’s CHEOPS exoplanet characterization satellite: the first detects planets with the in-transit method and the second studies them in depth, which allows it to obtain information such as size, mass and, from there, density. Among the alternative hypotheses considered is its birth from impacts between planets or the loss of its gaseous envelope, which they ended up discarding. Astrophysics has pending subjects. Beyond finding a clear mechanism, what seems evident is that observing this system of exoplanets opens up a range of possibilities about how planets form around stars that will last for years. Néstor Espinoza, an astronomer at the Space Telescope Science Institute in Baltimore who was not involved in the study, explains it for CNN: “This system provides a very interesting piece of information that planetary formation models will try to explain for years, and I am sure that we will learn something new about the planetary formation process once they are compared to each other.” In Xataka | How the solar system was formed: for the Earth to be born, a star had to die first In Xataka | We have been deceived by the distances of the Solar System: the closest neighbor to Neptune is Mercury Cover | NASA Hubble Space Telescope

The problem is not that your favorite influencer sells you the motorcycle. The problem is that maybe it doesn’t even exist.

What text-to-image and image-to-video generation will be able to achieve in the coming years is only easy to imagine if you’re in the business. I have been closely following advances in AI as a method to replace humans doing things. And I can assure you based on my experience that 2026 will be a before and after in a daily practice: consuming content on TikTok or Instagram. It’s happening now. We have been talking about influencers created with AI since 2023. The most famous case is that of Aitana Lopeza model created with AI that surpassed the barrier of 100,000 followers on Instagram. The case remained more anecdote than normal, but in 2025 we began to hear from relevant capital firms in Silicon Valley investing in start-ups created as synthetic influencer agencies. The factory. The girl you see above does not exist. She is an influencer that I created in less than two minutes and for free. If you want to make a minimal investment, you could improve the texture of your skin with Nano Banana Pro 4K or render additional details with Topaz AI. All within the same tool. Higgsfield AI is the largest AI content creation platform, and has had the “AI influencer” function for some time now. With the arrival of models like Banana Pro, the results are indistinguishable from reality. Skin enhancer in Higgsfield. Model created with AI. Maybe it exists… and it’s AI. Until now, we have only talked about creating influencers in a 100% artificial way but… what if I told you that you are already watching videos on social networks of people who exist, but who are not real at the moment you are watching the video? Spanish influencers, such as Janmolinerare starting to use AI to clone themselves and post videos in which they appear, but using an AI avatar that replaces them. This opens the doors to: Much higher content creation volume. Cost savings. What we hate with all our might: more ads created with AI. Indistinguishable. I have been training in this type of tools for some time, my eye is trained to try to detect when it is AI and when it is not, and since the arrival of the latest models I have one thing clear: it is currently indistinguishable from reality, and it will improve even more in the coming years. Big Tech. Microsoft, Google, Meta and Anthropic They are paying real money to content creators to promote their AI, with agreements reaching up to $600,000. The big question is whether, in the medium term, it will continue to make sense for companies to have humans advertise their products… or to have an AI announcing another AI.

Spanish companies have hired again in 2026. The problem is that there is no one to hire

by

Spanish companies start 2026 wanting to expand their workforce, but they face a big problem: they cannot find enough qualified candidates for your vacancies. According to the data of the ‘Labor Market Guide 2026‘ prepared by the consulting firm Hays, companies are ready to grow and hire more staff. However, the labor market has changed and professionals are already they don’t want to give up to their current jobs. Companies step up. The Hays study reflects that 81% of Spanish companies plan to increase their workforce during 2026. The economic growth trend drives the expansion objectives of Spanish companies and, to carry it out, new vacancies have been opened. This growth in job offers is especially noticeable in dynamic sectors such as technology, professional services and industry. However, the big obstacle quickly appears: there are not enough professionals with the necessary training to fill those vacancies. 93% of the companies consulted for the Hays study claim to have serious difficulties in find qualified profilesa percentage that reaches a historical record and is paralyzing many hiring plans. Talent shortage vs. little training. The lack of qualified professionals has become an insurmountable wall in the hiring processes for new vacancies. 85% of companies claim to have launched internal training programs to develop capabilities of its employees. Only 18% of participants openly admit that they are not investing enough in closing this skills gap that holds them back so much. From the employees’ side, the perception is different. Only 48% of employees are aware that training is being carried out in their company to improve their training. This disconnection between what companies promise and what workers see aggravates the situation, making it more difficult to attract and train talent. Qualified external talent is not found, but neither are resources allocated to train the talent that is already on staff. Less job rotation. Unlike what happened years ago, in 2026 professionals have prioritized stability and growth within their company, instead of jumping to another offer. This change in mentality represents a change with respect to the years 2022 and 2023 in which the labor market had high mobility and the workers they changed jobs frequently in search of better working conditions. Even so, 62% of workers feel that their salary does not reflect all the effort that they put in day by day, but that dissatisfaction is not enough to push them to movesince they value stability and personal balance more. Christopher Dottie, regional managing director of Hays for Southern and Western Europe, puts it in clear words: “companies continue to look for talent, while talent continues to look for stability.” Better salary and flexible working hours: keys to attracting talent. To break this inertia and attract available talent, 72% of companies plan salary increases in 2026, with increases of 7% in areas such as customer service, administration and finance, and 6% in the technology sector to meet salary expectations what candidates demand. Furthermore, the flexible days They are imposed as a key piece in attracting talent, although many companies still resist implementing them despite the fact that the vast majority of employees consider them essential for their well-being. In fact, this ability to adapt to demands for flexibility and offer teleworking options is what is tipping the balance. between the public and private sectors.
