Russia had managed to manufacture drones and missiles despite the sanctions. So selling Zara clothes was a matter of time

In recent months, a strange wave of western products has begun to reappear in places where, on paper, it is already they shouldn’t exist. Between geopolitical changes, forced business exits and an increasingly opaque market, certain brands have unexpectedly become visible again, fueling rumors, theories about how they are getting there and who is really pulling the strings of their distribution towards Moscow. Now a giant from Spain has (re)appeared: Inditex. A market that does not close completely. After announcing the end of operations in Russia a few days after the invasion of Ukraine, Inditex left behind its second largest market and sold its business in the country. However, more than two years latergarments with official labels from brands such as Zara, Bershka, Oysho, Stradivarius or Massimo Dutti have once again appeared on the shelves of the Russian channel Tvoenow renamed Tvoe n Ko, which boasts a “constantly updated” selection on social networks and presents the collections as almost clandestine finds. The pieces, which match models from previous seasons and carry prices in euros, are now sold in at least 19 stores Russian companies without there being (according to the official version offered) any contractual relationship between the Spanish company and the local distributor. In fact, they occur two months after the executive director of Inditex, Óscar García Maceiras, will declare to the Financial Times that the conditions “were not met” for his return to Russia. The engineering of the Russian gray market. I was counting a few hours ago the FT that the mechanism that allows the reappearance of these garments is based on the system of “parallel imports” established by Moscow to circumvent the massive departures of Western brands. In this scheme operates Disco Club LLCa Russian company that has recorded 18 statements in accordance, citing Inditex as supplier and presenting itself as its “authorized representative”, despite the fact that Inditex flatly denies having granted such permission. The garments come partly from inventories originally destined for various EU countries and partly from Chinese factories, according to labels and documents customs, in a circuit that takes advantage of legal loopholes and the Kremlin’s lack of inhibition to give formal coverage to a trade that would previously have been considered smuggling. The denial. For its part, Tvoe assures that it does not have direct agreements with Inditex and hides behind confidentiality agreements so as not to detail its suppliers, while Disco Club insist in which he only performed a “punctual technical service.” Burkhard Binder, the businessman linked to the founding of the company and based in Dubai, is disassociating himself from current operations. Inditex, known for its tight control of inventory, distribution and franchises, completely reject any link: he claims not to have authorized Disco Club or any Russian entity to act on his behalf and avoids commenting on how his products arrive in the country since he withdrew. Matter of time. we have been counting: the ability of the Russian economy to adapt in the midst of war has shown that international restrictions, no matter how strict, always find cracks. A country that has rebuilt chains complex supply chains to produce drones, precision ammunition or long-range missiles, despite technological embargoes and industrial vetoes, would not have difficulties reopening the door to much more “simpler” products, such as Western fashion clothing. In that context, the reappearance of garments of Zara in Russian stores is not so much surprising as confirming a trend: Moscow has perfected an ecosystem of parallel imports capable of circumventing almost any blockade, from military components even t-shirts and dresses from past seasons, turning the impossible into routine and the forbidden into a merely logistical problem. Russia, a laboratory of consumption in times of sanctions. The appearance of Zara products in Russia despite the exit from the company illustrates the magnitude of the gray market that Moscow has made official since 2022: an ecosystem that allows consumers to access Western brands through private intermediaries and indirect routes, without participation of the original companies. In this context, the reappearance of the Spanish firm in the Russian commercial landscape is not due to a business return, but rather to a state-run mechanism. commercial evasion that turns its garments into parallel import merchandise. If you like, the phenomenon also reveals the extent to which Russia has rebuilt its global consumption through third countries and front companies, and how even the strictest groups in controlling its supply chain cannot prevent its products from reappearing in a market from which they tried to leave definitely.

We have been searching for dark matter for 90 years. Now a Japanese man believes he has found his “fingerprint”

Since Fritz Zwicky suggested the existence of dark matter in 1933, the reality is that it has been one of the great ghosts of modern physics, generating many debates about its existence. The little we know indicates that this matter is there because we see how its gravity pushes galaxiesbut we have never been able to see it or touch it. It is invisible. Or at least, that’s what we believed until now. And to ‘see’ this matter you have to be a true superhero, since it does not emit, absorb or reflect light. Something that makes it completely invisible to telescopes around the world. But it is not something that is a small part of what surrounds us, but which makes up 85% of the total matter in the universe. But now there is hope to have more information about this great mystery of physics thanks to a study Professor Tomonori Totani of the University of Tokyo claims to have found the first direct evidence of this elusive substance. He has not seen it directly with his own eyes, but he has detected the “smoke” of his gun: a very specific gamma ray signal emanating from the halo of our own Milky Way and that eerily coincides with theoretical predictions of how dark matter behaves. A large amount of data. To understand the discovery, you have to look at the sky with gamma ray eyes. Totani has used a total of 15 years of data accumulated by NASA’s Fermi Gamma-ray Space Telescope (LAT). But the important thing was undoubtedly knowing where to look: in the galactic halo. That is, the ‘quiet’ outskirts of the Milky Way, excluding the galactic disk to avoid interference. What he found when cleaning the background noise was surprising: an excess of gamma rays with a very specific energy peak, located at 20 billion electron volts (20 GeV). The importance. So far so good, but… Why is it important? Basically, because it doesn’t fit what we would expect from normal astrophysical sources, like pulsars or supernova remnants. However, it fits like a glove for the WIMP theory. This is a theory that basically suggests that dark matter It is made up of WIMPs (Weakly Interacting Massive Particles). According to physical models, when two of these particles collide, they annihilate each other, releasing a cascade of energy in the form of gamma rays that would be detected in the universe now. And that is their conclusion: the detected signal is compatible with WIMP particles that have a mass of 500 times that of a proton. This would, therefore, be the fingerprint that gives the most information about dark matter, although it does not stop there. The shape is not a point on the map, but a soft, spherical halo that surrounds the galaxy, just as dark matter is distributed in the cosmological simulations that physics has made. The same goes for consistency, since the signal persists even when different background models are used and other known sources of noise in the universe are removed. There are precedents. This isn’t the first time someone has yelled “Eureka!” In the past, excess gamma rays have been detected at the Galactic Center (known as GCE), but the scientific community has tended to think that this signal comes from undetected millisecond pulsars, rather than dark matter. The key to Totani’s study is that he has looked where no one was looking in such detail. By moving away from the center and analyzing the diffuse halo, it is where he has found a much cleaner signal that does not invite so many doubts about its origin. There are still doubts. The study itself admits that the calculated cross section (the probability of interaction) is higher than the upper levels established by the observation of dwarf galaxies, which are often used as scale for dark matter. This means two things: either our models of the density of dark matter in the Milky Way are incorrect (which is possible, since there is a lot of uncertainty in the profile of the halo), or we are looking at a new and unknown astrophysical phenomenon that mimics dark matter. A great mystery. If this finding is confirmed, we would be facing one of the greatest discoveries in physics of the 21st century. It would confirm that dark matter is composed of particles that we can detect (and not primordial black holes) and open a new door for physics. go beyond the standard model. But as we say, this still needs to be verified by a second laboratory such as the Cherenkov Telescope Array Observatory (CTAO) that may have the ability to detect these gamma ray spectral lines.

The connected home is chaos. IKEA’s solution is 21 new devices compatible with Matter

IKEA has been wanting to be the protagonist of the connected home for years. In its catalog we have motorized blinds, door sensorswater leak detectors… The problem was getting everything to work cohesively and without friction. It is just what IKEA wants to change and to do so it has completely renewed its range of smart devices. with a total of 21 products, all compatible with Matter. Goal: full compatibility The promise of the connected home sounds great on paper, but the reality is that, if you have many devices at home, friction between them is the order of the day and in the end it is a chaos of different apps and hubs to be able to control them all. In statements to Wiredthe director of home electronics at IKEA confessed to having “more than 100 smart devices at home, but I also have like 10 different hubs. I hate it.” IKEA has been launching connected devices for many years and has a fairly large offering, but this launch is the recognition that Their offer was quite chaotic. For example, the first light bulbs and their controllers are compatible with the Zigbee standard, but later they launched the hub DIRECT Matter compatible. What they are looking for with this renewal of their offer is to get closer to that total compatibility and for everything to work with everything. To achieve this they have chosen mattera standard that was launched in 2022 and is present in devices from the main home automation platforms such as Amazon Alexa, Google Home, Samsung Smartthings or Apple HomeKit. Despite many devices already integrate itthere is still the problem that many older devices do not offer itbut it is undoubtedly a step in the right direction to solve this chaos. Lights, sensors and more IKEA’s new home automation range consists of a total of 21 products grouped into three large categories: lighting, sensors and control. First of all we have a new range of light bulbs called KAJPLATS. It consists of eleven different models. They will be dimmable and will also come in various shades of white, warm and colored light. In the case of sensors, there will be five models aimed at different use cases. They are the following: MYGGSPRAY: a motion sensor for both indoor and outdoor use. It is designed so that lights turn on automatically. MYGGBETT: It is a sensor to detect door or window openings and allows you to configure notifications. TIMMERFLOTE: to measure the temperature and humidity inside the home. ALPSTUGA: is the new sensor that measures air quality using CO2, temperature and humidity measurements. KLIPBOK: to detect water leaks. You can notify us with a beep or with a mobile notification Finally, BILRESA will be your new remote controls to control lights and GRILLPLATS will be the new smart plug. They will be available from December at prices yet to be confirmed, although IKEA claims they will be more affordable.

75% of the universe is made of unknown matter. Australia has gone to look for her 1 km underground

More than a kilometer underground, in an old gold mine in a small Australian town, a group of scientists is building a laboratory that aims to look where no one has been able to look before. Its name is SABER South, and its mission sounds simple but borders on the impossible: detect the particles that make up dark matter, that mysterious component of which, until now, we only sense its existence. The search begins. To understand how we got here, we have to travel back to 1998. That year, an experiment in the underground laboratory of Gran Sasso, in Italy, registered a strange signal which some interpreted as a clue to dark matter. That observation, known as DAMA/NaI, ignited a scientific career that has not stopped since. Now, Australia enters that global race. According to ABC News AustraliaSABER South will be the first dark matter detector in the southern hemisphere and will begin collecting data next year. Its director, physicist Phillip Urquijo, explains that the objective is to reproduce the Italian observations and check whether these signals are real or the product of interference from the environment. Currently, three other teams—in Italy, Spain and South Korea— they are still trying to replicate the original experiment. However, the Australian project has a unique advantage: its location in the southern hemisphere will allow the data to be compared with those from the north and rule out seasonal or local effects. The enigma of the invisible universe. Powered by the University of Melbourne and the ARC Center of Excellence for Dark Matter Particle Physics, seeks to understand the nature of a substance that surrounds everything, but that no one has ever seen. The Standard Model of physics accurately describes the particles and forces we know, but it still leaves too many gaps unfilled. One of the biggest is this: why don’t galaxies disintegrate? What holds them together if everything we see—planets, stars, gas, dust—barely adds up to 5% of the universe? The rest is hidden from view. The physicists They estimate that around 27% would be dark matter and another 68% would be dark energy. Physicist Elisabetta Barberio, director of the ARC Center of Excellence for Dark Matter Particle Physics, puts it bluntly: “Between 75% and 80% of the universe is made of something we can’t see or touch. This experiment brings us closer to discovering what most of the cosmos is really made of.” Therefore, if SABER South detects WIMPs —those hypothetical massive particles that interact weakly—, we would be facing a new form of matter and, perhaps, facing a physics that goes beyond the Standard Model. Simply put: it would demonstrate that almost everything that exists has a tangible structure. And every time humanity has understood a new force or particle, technologies that previously seemed like science fiction have appeared: semiconductors, lasers or magnetic resonance. A mine converted into a cosmic laboratory. The experiment is carried out at the Stawell Underground Physics Laboratory (SUPL), excavated 1,025 meters deep a distance that is equivalent to a protection of almost three kilometers of water, enough to block cosmic rays and natural radiation that could interfere with the measurements. The laboratory is air-conditioned, has filtered air and has data connections linking to the University of Melbourne. At its heart, a room-sized detector houses ultrapure sodium iodide (NaI) crystals. When a WIMP particle collides with an atom in the crystal, it produces a tiny flash of light, so weak that it lasts just a few nanoseconds. These flashes are captured by photomultiplier tubes (PMT), devices capable of transforming light into measurable electrical pulses. The crystals they are submerged in a scintillating liquid—linear alkylbenzene (LAB)—that acts as a “veto”: if the LAB detects light at the same time as the crystal, the event is discarded as background noise. The entire system is sealed inside a low-radioactivity stainless steel tank, surrounded by alternating layers of steel and polyethylene, and monitored from above by a muon detector. A machine that listens to itself. SABER South will operate almost autonomously. According to the technical reports of the projectthe system records in real time the temperature, humidity, detector voltage, nitrogen gas flow and even mine vibrations. If something goes out of normal values, it generates an automatic alert. In addition, human presence will be minimal: scientists will monitor the data remotely and will only access the laboratory for specific maintenance tasks. Even before its construction, the operation of the detector was simulated with the GEANT4 software, a tool also used by NASA and CERN. These simulations allowed us to estimate the background radiation levels and optimize the sensitivity of the system. Each light pulse captured will be analyzed with programs designed to distinguish between noise and possible real signals. Some are not optimistic. In a study by the University of Ottawa, physicist Rajendra P. Gupta poses that what we think we see as dark matter could just be a mathematical effect. Their model suggests that the fundamental constants of the universe could vary with time, and that the so-called “tired light”—the loss of energy of photons as they travel through space—would explain the observations that until now we attribute to an invisible mass. Waiting for the flash. For years to come, SABER South’s crystals will remain in the shadows of the mine, waiting for a flash so faint it could barely illuminate a speck of dust. If that signal is confirmed, it would be the first direct trace of dark matter, the invisible glue that holds galaxies together. But if it doesn’t appear, it will also be an answer: a sign that perhaps the universe works in a way we don’t yet understand. As detailed theoretical physicist Nicole Bellfrom the University of Melbourne: “This project represents the definitive quest to understand the world in which we live.” And perhaps, in that tiny spark beneath the ground, humanity will find the answer to a question it has been pursuing for decades: what is the universe actually made of?

We had been believing that dark matter existed. A new study believes that we were wrong

For decades, cosmology has been sustained on a pillar as fundamental as mysterious: The dark matter. The invisible glue that, according to the standard model, keeps galaxies together and prevents the stars from being fired by centrifugal force.Represents 27% of the universebut it has a problem: nobody has seen or detected it. It only trusts that it will be there. But now A published study in Galaxies This conception of the concept has changed. The study. Research led by the physicist Rajendra P. Gupta From the University of Ottawa proposes an idea as elegant as radical: what if dark matter does not really exist? According to his work, this ghost component could actually be an ‘illusion’, a side effect caused by something we were assumed: that the fundamental constants of nature are ‘constant’. The importance. To understand the magnitude of this proposal you must first remember the origin of the problem. Specifically, we have to go to the 70s, where astronomer Vera Rubin noticed that the stars at the edges of the galaxies revolved at the same speed those of the center. This completely challenged Newton’s laws, something that is as if a person sitting on the outer edge spinning at the same speed as a sitting near the axis. Physically, it should be triggered. The solution that the scientific community adopted was the existence of a “dark matter”, an invisible mass that generates the extra gravity necessary to maintain cohesive galaxy. This concept became the cornerstone of the cosmological model known as ΛCDM (Lamda-Cold Dark Matter). This model works incredibly well to explain the large -scale universe, but after searches with ultrasensitive detectors and experiments in the LHC We have not found a single particle of dark matter. It has always ‘detected’ indirectly through its gravitational effect on visible objects. The proposal. This is where Gupta’s idea enters. Its model, called CCC + TL (Covarying Couplening Constants + Tirad Light), is based on two different ideas. The first one is the so -called ‘Covriant coupling constants’ (CCC). In this case, the model suggests that the fundamental constants of physics, such as the speed of light (c) or the universal gravitation constant (G), are not fixed. Instead, they evolve and change as the universe expands. This is not a completely new idea (the physicist Paul Dirac already flirted with her), but Gupta integrates it into a complete cosmological model. The second idea raised in the investigation is that of ‘tired light’. A concept that arrives directly from the old hypothesis of ‘tired light’, which postulates that light loses energy throughout its trip through the cosmos. In this case, the Gupta model suggests that the redness of the light of the distant galaxies is not only due to the expansion of the universe but to a combination of both effects. Although the “tired light” as the only explanation, has been widely refuted, its inclusion in this hybrid model is key to its calculations. New terms. Once these two new ideas are taken into account, it is time to modify Einstein’s field equations with these variable constants, the GUPTA model makes new mathematical terms appear. This is something that the author has baptized as “α-material” and “α-energy.” And this is where it is true magic: these terms, which are not a physical substance but an effect of the evolution of the laws of physics, generate the extra gravitational attraction that until now we attributed to dark matter. Dark matter would not be something to find, but a mathematical mirage. It is tested. Something to keep in mind is that theories can be very well written and look very good on paper, but logically they have to demonstrate. For this, Gupta used the SPARC database, a high quality catalog with the rotation curves of 175 galaxies. The method used was the reverse to the traditional. Instead of adding dark matter to justify rotation curves, Gupta took the curves observed and used its model to “subtract” the effect of “α-material”. The result should be the rotation curve generated only by visible (barionic) matter. Something that has wanted to materialize in a graphic taking as an example the NGC3198 galaxy. In this image, the blue line (VO) is the rotation speed observed in the galaxy. The points line (VB) is the speed that should have if only the visible matter existed, according to the estimates of SPARC and the discontinuous line (VBX) is the prediction of visible matter calculated by the GUPTA model. The similarity between the prediction of its model and the estimation of barionic matter is remarkable. Something that the author repeated for several galaxies with promising results to give a very forceful conclusion. A new paradigm. If the CCC+TL model is correct, its implications are huge. Not only would it eliminate the need for dark matter, but, according to the author, it could also explain dark energy and other cosmological enigmas, such as why the first galaxies Observed by James Webb They seem more mature than they should. You have to be cautious. This is, for now, a “proof of concept” as the author himself points out. This means that it is using simplifications, such as treating galaxies as perfect spheres, something that is far from reality in the universe. In addition, its dependence on “tired light” is a friction point with conventional cosmology. Models such as this should demonstrate that they can explain with the same precision as λCDM Key observations such as microwave background radiation or the accelerated expansion of the universe. A new advance. But what is clear with this research is that the scientific community is exploring alternatives, especially when the predominant model presents fissures, such as the absence of a direct proof of dark matter. The Gupta model is, for now, a fascinating possibility. A reminder that in science, the most entrenched truths can be questioned and that the solution to the greatest mysteries of the universe might not be to find something new, but in … Read more

Apple has succumbed to what was resisted for years: megapixels do matter

Apple has already celebrated the traditional Keynote to present your devices For the coming months. He has renewed his three Apple Watch families (with the Series 11, SE 3 and the Ultra 3), but we also have some Airpods pro 3 that began to be necessary. The main course, as usual, are the mobiles and we already have on the table the iPhone 17he iPhone 17 Pro and the iPhone Air that arrives to compete the curious Superdelgados playground. Much of what is presented is conservative, but we had something very curious that does not usually happen with those of Cupertino: They have marcheds. Twice, in addition, and with two decisions that concern a single model: the iPhone 17 Pro. The first is rectifying with the materials, passing the glass and the titanium to aluminum, being a Better material to solve a problem that the iPhone have been dragging for years. The second has to do with the megapixels of the Telefoto camera. Because for years Each new iPhone defended that the telephoto only had 12 megapixelsnow they take chest with a new 48 megapixel sensor. And with an optical zoom that is 4x instead of 5x of the last generations. The 48 megapixels of the iPhone 17 Pro Telefoto When the rest of the mobile industry He embarked on a race to conquer the megapixels (24, 48, 64 megapixels that strengthened in the mid -range, 108 and even 200 megapixels), There were a few companies that remained faithful to their philosophy: Google and Apple. Not directly, but implicit in their presentations, both defended that the 12 megapixels allowed sensors with pixels of a larger size, improving the capture of light and, at the same time, allowing computational photography to be carried out with agility (without long waiting times in the process) and with files of a contained size. Because climbing megapixels has a weight in the result: The same is not processed A photo at 12 mpx than one at 50 MPX and, the smaller the pixel of a sensor, the more megapixels, but less light “catch” and there are worst results with high lights and with shadows, for example. But the day arrived: Google went up to 50 megapixels with the Pixel 6 Pro and Apple did the same reaching the 48 megapixels with the iPhone 14 Pro. The approach of both has gone very hand, using those extra megapixels to make available to the user A 2X digital zoom which is a sensor cut. This has been called for years “zoom with optical quality”, not “optical zoom” because the software uses the main camera as hardware, but virtually cut the sensor to make that 2x increase. Quality is, in many cases, indistinguishable to that of a photo taken with a 2x optical. It would be necessary to talk that the focal distance of a 2x optical offers a different perspective, but in terms of image quality, those 2x of iPhone and Pixel are excellent. However, while the rest of the competition mounted sensors with more megapixels in all its cameras, Apple kept the telephoto anchored in the 12 megapixels. And so since they premiered it in the iPhone 7 Pluswhich is said soon. Telefoto sensors were being more and larger, yes, but the resolution did not change and that had a price: the digital zoom of the iPhone from the optical zoom of each generation (2x for years, but later 3x and 5x) It was far behind the rest of the industry. With increasingly present and mobile computational photography with an increasingly clear zoom thanks to that hardware mixture (lenses + megapixels) and software, Apple was staying behind. Until now. Finally, those of Cupertino have taken a step forward with three cameras with 48 megapixels. Thus, photos can be taken at full resolution or use the factory resolution (12 megapixels, but with larger virtual pixels to improve photography exposure and control size), but above all, allow a higher quality digital zoom. With the iPhone 17 Pro, Apple states that It is “how to have eight professional goals in your pocket” And, far from the brave marketing, they are part of reason. The iPhone 17 Pro has three cameras: Wide angle or 0.5x Main or 1x 4x Telefoto But, with different clippings of the sensor and the macro mode using the wide angle, we get 1.2x, 1.5x and 2x “hybrids” and one step further: an 8x that will be the one that applies the same formula as the 2x a couple of years ago: a cutting of the 48 megapixel sensor of the telephoto. In addition, it is a sensor 56% larger than the previous one, so photodiodes will also have an adequate size. On paper, It is more user versatilityand about practice is good news. It is true that the word “digital” has a tremendously negative connotation when we talk about the zoom due both to what the digital cameras did years ago and to the digital results of the mobile themselves, but with those clippings of the sensor that are achieved using large sensors And with a lot of megapixels, the thing changes. Photos with the 3X optical honor Magic V5 and with the 10x “hybrid”. Quality is brutal | Photo: Xataka It is Apple surrendering to evidence And, although we have to wait for the analysis of the iPhone 17 Pro to test these cameras, examples such as those seen with the Honor Magic V5he Pixel 10 Pro or the Samsung Galaxy S25 UltraThey allow us to excite ourselves with that 8x “of optical quality.” Now, there are those who can see it as a step back with respect to the 5x optical of the iPhone 16 Pro and iPhone 15 pro maxbut from my experience with the 2x hybrid of the iPhone (even of the 16 base), I think it is a movement in the right direction. And it is also about to see how the strictly digital zoom behaves beyond that 8x … Read more

Sending an email to a low employee has cost 1,500 euros to a company: it doesn’t matter if you respond or not

The Superior Court of Xustiza de Galicia (TSXG) has marked a before and after in the protection of the right to digital disconnection of workers in Spain. For the first time, a company has been convicted of sending electronic jobs to an employee who was on a medical leave. The sentence is considered a pioneer because, although other countries Like France and BelgiumThey have already legislated on digital disconnectionGalician justice has taken another step by sanctioning not only the obligation not to respond, but also the duty of the company of Do not send communications Out of working hours. What happened? According to details the sentencethe affected worker was in a situation of temporary disability due to an “anxiety disorder”, apparently “motivated by the emotional wear that implies the current situation of excess work, realization of overtime continuously and labor responsibility, which has led to the appearance of relational insecurity with respect to their environment.” In that context of medical disabilitythe employee continued to receive electronic emails related to her work during the entire low period. The company recognized the facts, but argued that the emails to the complainant were part of a thread created above and whose content was aimed at other people of the team. In addition, he claimed that they were not asked for “an immediate response.” In Xataka 40,000 euros for a croquette: Mercadona dismissed an employee for eating a croquette and must now compensate him The TSXG got serious with disconnection. In its resolution, the Superior Court dismissed the company’s arguments and was overwhelming in its ruling. The magistrates considered that the company not only breached their duty to refrain from communicating with the worker during his temporary disability, but also attempted against his moral integrity. According to the sentence, the Right to digital disconnection “It demands that communications from the company are not received outside the work time”, and warns that “that right is not fulfilled due to the fact that the working person does not have the duty to respond to the communications received outside the work time more or less immediately.” That is, and here the Importance of this resolutionthat the right to digital disconnection does not only refer to the interpretation of the urgency of the communications received, but “carries with it an obligation by the employer, and of dependent or linked persons, of abstention in the communications of labor order or linked to the provision of services outside the working time.” In Xataka Some employees sued their company for cutting the salary. The supreme has responded that being unpunctual is not a job Vulnerability situation. The TSXG highlights the special importance of the right to digital disconnection when the worker is in a situation of temporary disability by A psychic ailment. In the sentence, the Galician Court emphasizes that emails in these circumstances “uneasy the receiver, and also reifted it and undermined their dignity” and places the worker in a state of permanent availability incompatible with her right to recover without pressures. The right to digital disconnection in Spanish law. The right to digital disconnection is included in article 88 of the Organic Law 3/2018 and reinforced with the arrival of the call Distance Labor Law of 2021. According to the regulations, “all workers and public employees will have the right to digital disconnection in order to guarantee, outside the legal or conventionally established work time, respect for their rest time, permits and vacations, as well as their personal and family intimacy.” This right allows workers not to answer mails, calls, video calls or any other digital communication out of work hours. The law does not differentiate between the size of the workforce or the public or private nature of the company, so the protection is universal for all employees in Spain. With the TSXG ruling, the prohibition is not limited to the fact of “not answering” but its interpretation is expanded to “not receive.” {“Videid”: “X919SE0”, “Autoplay”: False, “Title”: “The AI ​​and the future of our work Silvia Rivela | 100 years, 100 visions Ep.3”, “Tag”: “”, “Duration”: “2630”} Symbolic condemnation, but pioneer. The process reached the TSXG as a result of a previous sentence in which, in addition to the violation of the right to digital disconnection of workers, compensation for violations of the right to honor and physical integrity were requested. In this case, the new resolution revokes these last two concepts because it has not been damaged physically or its honorability has been affected. However, it imposes compensation of 1,500 euros “for damages” for violating the right to digital disconnection because the company “was not guaranteed” of this right and points out that “pretending that it is available at any time of its life, including temporary disability, prevents the free development of personality and hinders the exercise of the field of intimacy of personal life of personal life.” In Xataka | 55,245 euros for eating a sandwich and a beer: Mercadona must compensate an employee for unfair dismissal Image | Unspash (Brian J.

We have found the matter that was missing in the universe. I was hidden in the filaments of the cosmic network

Where is the dark matter is one of the great mysteries of the cosmos, but if someone thought we had all the barionic matter (the “conventional” matter) in the cosmos … it was wrong. At least until now. What was missing. A new study He has found in the cosmic network the barionic matter that remained hidden and that would represent about half of the “conventional” matter of the universe (matter which in turn only represents about 15% of the total matter). He has achieved it thanks to rapid radio (FRB) bursts, mysterious radio wave bursts that run the cosmos occasionally and have served to “illuminate” the subject of this intergalactic network. A network of “highways” in space. The cosmic network is a series of filaments of enormous size located in the intergalactic space in which a good part of the subject of the universe is distributed. These filaments are stretched clouds of gas and particles whose characteristics We discover little by little. Recent studies had documented the existence of this elusive network. The fact that the gas and particles that compose it are inert and do not give off light made their observation very difficult, which required hundreds of hours of dedication by powerful telescopes like VLT (Vary Large Telescope) of the European Observatory Austral (ESO). DSA-110. For study, the team had to build its own observatory in the California desert, in DSA (Deep synoptic array) -110. The name DSA-110 refers to the fact that this is a telescope composed of a network of 110 antennas. FRB The new Observatory was responsible for the detection of 39 of the 69 FRB thanks to which the deccovement was possible. These bursts are intense intriguing radio signals that we occasionally receive from the cosmos. We do not know exactly its cause or causes, but we suspect that they can be caused by supernovae or similar events. Some of these frb are repeated periodically while others are punctual; The origin of some can be located in a concrete galaxy, that of others does not. The frb used in the study They had their origin at points located at distances between 11.74 million light years and 9,100 million light years. This last distance, marked by the event FRB 20230521B, now marks a record: that of the most distant gust detected. Illuminating the highway. According to Explain the team itself Responsible for the study, the FRB “shine through the fog of the intergalactic medium.” When studying how this light stops when you meet matter, it is possible to measure this mist. When crossing the filaments, the frb light also separates in different wavelengths, such as when we see that a white light breaks down when crossing a prism, generating an rainbow. The measure to which the light decomposes also offers key information about the medium that is going through. The details of the study were published In an article In the magazine Nature Astronomy. Halos or networks. So far the cosmological models indicated that there was more barionic matter in the universe than we were able to observe. The new estimate of the mass of the huge filaments of the cosmic network allows us to fill in these holes. The new estimate indicates that 76% of the conventional matter of the cosmos is in the intergalactic environment, while 15% would be in the “halos” of the galaxies, while the rest, about 9% of this matter, would be the subject of which the interior of the galaxies is composed: planet stars and everything that lives are already vast cosmic structures.

We have a new explanation for dark matter. We have found it in superconductivity

Dark matter remains one of the great mysteries that intrigue astrophysicists around the world. The existence of this matter is assumed by the generally accepted cosmological models, but when determining the nature of the elusive matter we only have more or less founded conjectures and speculation. A new explanation. A group of researchers has proposed a new mathematical model which offers an explanation of the nature and origin of dark matter. The origin of this matter would be in the Big Bangas a consequence of the collision of high -energy and no mass particles, which would have won a great mass after their union. “Dark matter began its life as relativistic particles with hardly any mass, almost like light,” pointed in a press release Robert Caldwell, co -author of the study. “It is totally antithetical about what is usually believed to be dark matter (…). Our theory tries to explain how it was light to become masses.” Perhaps the most important detail in this work is that the theory postulated by this team can be tested thanks to the cosmic microwave background (CMB). The dark matter. The Dark matter It is the proposed explanation to explain a series of anomalies observed in the movement of the great objects of the observable universe as galactic galaxies and clusters. If we analyze their movements and compare them with the models used to describe them, such as the theory of relativity, we encounter that something does not match. Something seems to be pulling the matter. The dark matter would be different from the conventional or barionic in the fact that it would not interact with the rest of known physical particles except in one way: through gravity. That is why it would be so elusive despite the fact that its gravitational influence is still apparent. According to estimates, dark matter represents 85% of the matter of the universe. Return to Big Bang. The new proposed hypothesis Point out that fast particles, similar to photons, were the ones that dominated the universe after the “burst” of the big Bang. However, in that initial “chaos”, these particles would have joined in pairs. As postulate, the spin, one of the properties of the subatomic particles, would have exerted magnet among these particles: as if it were objects with opposite poles, the opposite spins of the particles would have caused the fusion. The hypothesis also proposes that, when these particles are cooling over time, the “imbalance in its spins” would have caused a drastic reduction in its energy, resulting in cold and heavy particles, dark matter. The “inspiration” for this model would have come from an analogous phenomenon seen in electrons, in the Cooper’s pairs, which allows electrical conduction without resistance, superconductivity. The details of the study were published In an article In the magazine Physical Review Letters. Putting the theory to the test. One of the great strengths of this hypothesis is that it is possible to test it. The key is that, according to the model, this “non -relativistic mass condensate” would decide faster than the standard scenario predicts. Explains the team that this prediction can be tested thanks to the cosmic microwave background, a type of radiation remnant Big Bang.
