These are my 5 favorite models

Spring means the arrival of heat after winter, but also the appearance of allergies to pollen, grasses and many plants and trees. For this, having good sunglasses can be a before and after, especially if they are enveloping. But… what do you have to take into account when buying one of these glasses? These are the most important points: The design: It is necessary that the frame has a curved shape and not a straight one, since this way it will protect us from the front and the sides of our eyes. The function is to create a physical barrier that prevents the wind from entering through the holes in the glasses. Side protection: Although the curved frame plays a fundamental role, it is also especially interesting to have wide temples. In this way, we will have better protection on the sides. The distance: It is important to keep in mind that this type of wraparound glasses must fit very well to achieve a more airtight effect. As a recommendation, it is interesting that they stay tight to the cheekbones, but without the crystals touching the eyelashes. Polarized lenses: During allergy, one of the symptoms is sensitivity to light. The lenses themselves will protect us from this, but if they are also polarized, much better because they can prevent the eyes from becoming more irritated. UV protection: Some glasses also have a quality UV filter against ultraviolet radiation, a particularly interesting protection when spending a lot of time in the sun. Now, taking this into account, What glasses should I buy? There is a lot to choose from with very varied prices, so we have made a selection for different budgets. Radiant Hawkers by 29.80 euroswith UV protection against ultraviolet radiation. Polaroid 7886 by 33.36 eurosinexpensive glasses with thick temples and polarized lenses. Nautica N2239S by 59 euroswith double protection against ultraviolet radiation and polarized lenses. Nike WindTrack Heat by 89 eurosglasses with a more sporty design that have UV protection. Ray-Ban RB4335 by 137 eurosglasses with very wide temples and UV protection. The price could vary. We earn commission from these links Radiant Hawkers If you want to go cheap, the Hawkers Radiance They are sunglasses that, for 29.80 euroshave a wrap-around format in the frame, since it presents a curvature. They have UV protection against ultraviolet radiation and are capable of absorbing, depending on the brand, between 82 and 92% of sunlight. Of course, they are not polarized and the lenses slightly cover the sides of the eyes, but not the temples. The price could vary. We earn commission from these links Polaroid 7886 With a similar price, 33.36 euros In this case, we find the Polaroid 7886sunglasses that also have a curvature in the frame as well as wide temples to further protect the sides of the eyes. They are polarized. In addition, Amazon customers often highlight that they are quite comfortable thanks to their flexible design, which allows them to better adapt to each face shape. The price could vary. We earn commission from these links Nautica N2239S El Corte Inglés also has the Nautica N2239S for a price of 59 euros. They are especially interesting glasses due to their design, since they have an enveloping curved format as well as thick temples. We must also highlight the double protection of the polarized lenses and their UV filters against ultraviolet radiation. The price could vary. We earn commission from these links Nike WindTrack Heat On the other hand, if you prefer something more sporty, El Corte Inglés also has the Nike WindTrack Heatin this case for a price of 89 euros. They are glasses that protect above all thanks to their great curvature in the frame, and not so much because of the temples because they are somewhat thin. They also come with UV protection against ultraviolet radiation, although they are not polarized. The price could vary. We earn commission from these links Ray-Ban RB4335 Ray-Ban has a very characteristic style in its glasses and the Ray-Ban RB4335 They are especially interesting for allergies. Because? Because of its format, which not only has an enveloping curvature, but also because of the wide temples that it includes. The lenses are not polarized, but they do have UV protection. Its price in this case is 137 euros. The price could vary. We earn commission from these links Some of the links in this article are affiliated and may provide a benefit to Xataka.

The latest whim of millionaires is to build a luxury superyacht around a living tree

by

I will not deny that they die on me even plastic plants, but there are people who have a gift with plants. Others, however, are capable of buying a 73-meter superyacht built around a treely keep him alive as he crosses the seven seas with every luxury imaginable. He Virtuosity It is the second ship of the 74 Steel series from the Italian shipyard Sanlorenzo. Its construction and design took more than four years to materialize. For the first 18 months, the owner and the Sanlorenzo team held weekly calls before design even began. It’s not that there was any doubt: it’s that when someone decides that their new ship will revolve around a living tree, details matter and a lot. The tree that wanted to be a sailor The vegetal protagonist of Virtuosity It is a Ficus Nitida, also known as Indian laurel, planted on the main deck of a luxury superyacht with a modern and elegant design. It is worth noting that the tree in question was not added when the yacht was already built, but was selected before the first structural block of the ship was assembled, and the entire yacht was built around it. So that the plant receives sunlight in its lower parts, two side skylights were installed at ground level and its trunk rises across two decks to let its leaves breathe while looking out over the sea from one of its exterior decks. The tree occupies about 16 square meters in the center of the yacht’s main salon. The tree passes through two covers “With this yacht we decided to rethink the onboard architecture from its very foundations,” explained Tommaso Vincenzi, CEO of Sanlorenzo, to Superyatchtimes. “From the integration of living nature to the transformation of technical volumes into experiential environments, each decision is based on a clear architectural vision,” he added. Details that go beyond luxury As if having a five-meter-high tree on the deck might not be enough, the Virtuosity It also hides one more peculiarity below the waterline: an aquarium so big like the sea On the lower decks we find a 35 m2 wellness area. This room is located right on the waterline of the yacht, allowing guests to observe marine life directly from their seats through a large glass surface of the hull. Without a doubt a quite sophisticated way to see fish without even having to get wet. This wellness area also includes a hammam, sauna and massage room. The master suite of Virtuosity It occupies its own deck with 40 m2 and has a bed facing forward with a dressing room and bathroom while on the main deck there is a second VIP suite and two more cabins for guests. At the owner’s request, a reflecting pool was installed in front of that suite, designed so that the water reflects the sky and sunlight, far from the concept of a conventional pool. A cinema lounge aft and a sensory shower forward complete what the manufacturer describes as a private apartment within the ship itself. By day, the stern of the Virtuosity It functions as a relaxation area with direct access to the water and water toys. At night, and also at the express request of the owner, the beach club is transformed into a nightclub with a permanently installed DJ booth. That someone included a fixed nightclub on their list of requirements for a superyacht says a lot about how this owner understands the vacation at sea. This beach club has been redesigned and is 40% larger than that of the first 74 Steel delivered in 2025. In addition, a glass-bottom pool was installed on this deck that acts as a 28-square-meter skylight to illuminate the lower deck. The triple-height main deck features an exposed wine cellar and a spiral staircase in dark lacquered aluminum, as well as an elevator. A helipad and sports deck are located at the bow of the ship. With 73 meters in length and 13.1 meters in beam (width), the Virtuosity It can accommodate up to 12 guests in 6 cabins and a crew of up to 24 people. Its propulsion system is diesel-electric, with six 700 HP Volvo D13-700 engines and 425 ekW alternators, the same technical package as the first 74 Steel, the Silver Fox. With 180,000 liters of fuel on board, it reaches a range of 6,000 nautical miles at 11 knots and a maximum speed of 15 knots. Power and luxury for the only superyacht where you can boast of having taken a nap under the shade of a tree in the middle of the ocean.

the funnel is a fatal trap knocking down only two ships

by

In 1988, during the call Operation Praying MantisIn a single day, the United States launched the largest naval offensive since World War II in the Persian Gulf, destroying a large part of the Iranian fleet after a mine hit an American frigate. That episode, which seemed to close a chapter, ended up marking the beginning of a completely different form of understand war at sea. A lock to strangle… or expose yourself. The United States has opted for one of the most aggressive tools available: block traffic to and from Iranian ports in the Strait of Hormuz to suffocate its economy, deploying a combination of aircraft carriers, destroyers, special forces and air support with the ability to intercept, board and detain oil tankers. The operation, however, does not consist of simply turning off a tap, but rather of monitoring and controlling a maritime funnel extremely narrow and saturatedwhere each movement forces high-value assets to move closer to the Iranian coast. This proximity, necessary to make the blockade effective, turns each maneuver into constant exposure to attacks, raising the potential cost of the operation from the first moment. The military paradox. A key point appears here, because, although the United States has devastated the Iranian conventional navy, sinking frigates, corvettes and large units, the true instrument of control of Hormuz still stands: the asymmetric fleet of the Revolutionary Guard. Talk later of more than 60% of their speedboats that remain operational, hidden in underground bases and specifically designed to operate in confined waters, launch lightning attacks, lay mines or harass commercial ships. In fact, this structure has not only survived, but has proven itself effectively. drastically reducing maritime traffic, making it clear that traditional naval power is not the decisive factor in this scenario. The strait turned into a weapon. This morning they counted the TWZ analysts that there is a wave of US minesweepers currently moving from Japan to the Middle East. The move is easy to understand, since Iran has transformed the strait in a hostile environment where any technological superiority loses part of its advantage in the face of saturation and difficulty of detection. Naval mines, explosive drones, ground-launched missiles and small fast vessels create a distributed threat network that does not need to sink large vessels to be effective. It is enough to generate uncertainty and constant risk to paralyze trafficmake insurance more expensive and deter shipping companies, as has already been seen with dozens of attacks and the drop in the number of daily crossings to minimum levels. Strategic funnel: control or get trapped. Because the US plan to “bottle” Iran on both sides of the Strait involves deploying forces in the Gulf of Oman and the Persian Gulf to cut entrances and exits, but that same geometry makes the operation in a potential trap. As? A priori, the forces must operate within a corridor barely 30 km wide, under direct range of coastal missiles and surrounded by low-cost but high-impact threats. In this context, control of space does not eliminate risk, but it concentrates itforcing ships to remain within an area where the adversary has designed its way of fighting for decades. The critical point. Under that scenario, the logic of the confrontation favors Iran in one key respect, because it does not actually need to defeat the US navy as a whole, only to inflict limited losses, but symbolically devastating. Hence, as the retired admiral of the United States Navy, James Stavridis, explained, to CNNthe sinking or disabling of one or two Washington destroyers, or the damage to a single aircraft carrier, would not change the global military balance, but it would have an impact unprecedented political and strategicquestioning the entire operation in itself. In essence, a simple explanation: in an environment where attacks can come in the form of swarms of drones or relatively cheap missiles, the cost-benefit leans dangerously against whoever deploys the most valuable assets. Time, economy and global pressure. Not only that. While the blockade seeks to cut off Iranian income, its collateral effects are already hitting the global system: rise in oil prices above $100, tensions in fuel supplies, impact on aviation, fertilizers and industrial chains. Iran is precisely playing with this wear and tear, aware that prolonging the crisis increases the pressure on the United States and its allies, both economically and politically. In this scenario, every day that the strait remains altered reinforces the Iranian negotiating position, turning the blockade into a double-edged sword. Decades waiting for the battle. If you will, the latest analysis of the situation in Hormuz is perhaps the most disturbing for Washington’s interests. Far from being a surprise, the scenario fits exactly with the doctrine that Iran developed after the destruction of his fleet in the eighties: avoid conventional combat and dominate critical points through asymmetric warfare. The Strait of Hormuz is not just a strategic passage, but a battlefield custom designedone where the combination of geography, preparation and tools allows Tehran compensate for their inferiority in the face of an extremely superior naval power. Therefore, more than a decisive move, the US blockade opens the door to a confrontation on the ground where Iran it feels more comfortable and where the risk of an unpredictable escalation is maximum if Tehran is able to knock down a couple of “chips.” Image | Iran State Media In Xataka | The problem in Hormuz is not that it is closed: it is that Iran has “lost the keys” and without them the balance is broken In Xataka | The most buoyant market right now is selling streaming and satellite images of US movements to Iran.

“Hell is other people”

by

The history of philosophy is full of round phrases that (in theory) synthesize the way of thinking of their authors. Also from ambiguous interpretations or directly wrong. Perhaps the clearest case is made by Jean-Paul Sartre, one of the icons of existentialism. Often his phrase “Hell is other people” It is understood in its most literal and stark sense, as if it were the misanthropic cry of someone tired of living in society. It’s not like that. Sartre himself was in charge of clarifying it. An unexpected hell. In Jean-Paul Sartre (1905-1980) there was a double quality that does not always accompany the great philosophers. A deep look. And an ability to express complex theories in a clear, even engaging way. Hence, he expressed his way of seeing the world both in essays and in novels, scripts and plays. The phrase in question comes from one of the latter, ‘Huis Clos’from 1944, which is usually translated into Spanish as ‘In camera’. In it, the French philosopher presents us with three characters (one man, two women) trapped in a room. The interesting thing comes when we understand that the room in question is hell and the actors we see on stage represent condemned souls. The three of them expect the kind of torture they have read about and seen in pictures, but as time passes they realize that nothing happens. No devils with tridents or flames. No Dantesque scenes. Nothing remotely resembling ‘The Garden of Delights’ of Bosco. “L’enfer, c’est les autres”. Throughout the play, each of the three characters confesses their story and the sins they committed in life, weaving a frustrating love triangle. Towards the end of the performance, one of them, Garcin, utters what is perhaps the most resounding and certainly the most famous phrase, not only of the work itself, but of Sartre’s entire legacy: “I would never have believed it… Remember? The sulfur, the bonfire, the grill… Ah! What a joke. There is no need for grills, hell is the Others.” To be more precise, what Sartre wrote in the original, in French, was “L’enfer, c’est les autres”so there are those who have believed that the translation “Hell is the Other” better fits the author’s intention. Well, it’s pretty clear, isn’t it? Not so much, actually. If literature (art in general) has something good, it is that it can be discussed, but since practically the 1940s, readers and viewers of ‘Huis Clos’ have tended to interpret Garcin’s phrase in a way that is not entirely correct. Not so much because it is erroneous in itself but because it impoverishes the meaning that its author wanted to give it. We know that Sartre was an atheist, so it is not unreasonable to think that when he presents us with a personal hell, without torture, devils or rivers of lava, what he wants to suggest to us is that in reality our authentic condemnation is “the Other”, the obligation to understand each other with the people with whom we share our time, just like the prisoners of ‘Huis Clos’, right? “The executioner is each one for the other two”, comes to say at one point in the play one of the characters. “It has been misunderstood”. The truth is that the above is a simplistic approach. Of course, that is not the meaning that Satre wanted to give to his words. And we know this not because critics or academics dedicated to studying the work and life of the French author have suggested it. No. It was Sartre himself who, in 1964, years after premiering the work, he complained that his misinterpretation. “‘Hell is other people’ has always been misinterpreted. It has been thought that with that phrase I meant that our relationships with others are always poisoned, that they are invariably hellish relationships. But what I really mean is something totally different,” clarifies the philosopher. “I mean that if relationships with another person are distorted, flawed, then that other person can only be hell. Why? Because… when we think about ourselves, when we try to know ourselves… we use the knowledge that others have about us.” And what does that mean exactly? The fundamental thing is not so much how we deal with others or whether this is easy or complicated for us, but how we build our self-understanding. It is best understood with the metaphor of “mirrors”, a tool that is also very present in Sartre’s play. When we want to know what we are like physically, on the outside, it is easy for us: we resort to the reflection that the glass returns to us. But… How do we form our self-knowledge? “When we try to know ourselves, we use the knowledge that others have about us,” Sartre explains to uswho warns however that the ‘reflection’ we receive in that case is not like that of the crystals. “We are judged with the means that others have and have given us. In everything I say about myself, someone else’s judgment always enters. In everything I feel inside, another’s judgment enters. That does not mean at all that one cannot have relationships with other people. It only highlights the fundamental importance of all other people for each of us,” insist the philosopher Trapped characters. The three characters in ‘Huis Clos’ are trapped, but not (alone) in a closed room. Each one of them is a prisoner of the judgment that the rest have made of him in a complex relationship. That is his true punishment, his hell, not the monsters and flames that we see in Hieronymus Bosch’s paintings. Their penance is that the three characters are condemned to define themselves through the “distorting mirrors” of their companions, people who give them a negative reflection and in turn cause the same effect, adds Kirb Woodward.. Sartre himself poses this concept of the tyranny of “being for others” in another way in ‘Being and nothingness’: “By the mere appearance of the Other I see myself in … Read more

We knew that lynxes were smart, but not that smart. Five females from Toledo have just rewritten what we thought we knew about wild felids

by

Science works like this. One day, a member of the Hunting Resources Research Institute is reviewing trapping cameras, and the next, this research team is rewriting many of the things we thought we knew about terrestrial carnivores. And also for a handful of mothers taking care of their children. What has happened? As I said, a team led by IREC has used trapping cameras to document for the first time as females iberian lynx They deliberately immerse freshly hunted rabbits in basins of water before giving them to their young. It may seem like an ethological curiosity; but we are talking about the first known case (eight different events) of deliberate manipulation of dams with water (in five different pylons) by wild felids. A complex cognitive behavior that we did not think was possible. And it’s curious because it’s not a “put in and take out,” or anything like that. It is not at all subtle, nor easily confused with something else: lynxes maintain the dive for more than 60 seconds without letting go of the prey and they do it, of course, completely on purpose. Why do they do it? Well the truth is that they don’t know. The researchers point out that the females could be using the rabbits as a vehicle for water to their young in especially hot periods. It must also be taken into account that the puppies are just weaned at that time of year. However, as I say, we don’t know for sure. Why is it important? Until now we had found many cases of animals that They washed their food in water (Japanese and Thai macaques; great apes in captivity, wild boars and cockatoos), but all in omivorous or frugivorous species that used this manipulation to remove sand and dirt. We had never seen a carnivore doing it. But the interest goes beyond that. Because not only does it challenge the idea that terrestrial carnivores capture and hide their prey without manipulating them; but rather questions the idea that solitary lynxes do not have a great capacity for social transmission. This finding suggests the opposite: that there is what we could call a “lynx culture“. Things that separate each other. We know so little… That is the main conclusion of the series of studies that this team is developing in the Montes de Toledo: that although we have been living with animals and plants for centuries, there are many things (too many) that we still do not know. Above all, when they have to do with this: with animals that are getting closer and closer to what we have called ‘humanity’ for years.

there is no RAM for everyone and hyperscalers have absolute priority

by

When Gabe Newell, head of Valve, asked for help a few weeks ago to find RAM memory anyway and be able to take out his Steam Machine, the comment was half joking… half serious. It was planted in the same GDC in which NVIDIA took advantage of its technology of artificial intelligence to beg beg for some RAM. It was not a situation that caught us by surprise, since we have had quite negative news since 2025 regarding memory supply. RAM, SSD, hard drives and any element that the monster data centers to function. But the wheel does not stop, devices must continue to be launched and the problem is that, beyond the initial ‘run’, no one knows very well if they will be able to continue selling the hardware. And it is a problem that concerns even Apple. Neither one of the main clients of a giant like TSMC is above the needs of the hyperscalers. And he is already suffering the consequences: They have stopped selling Mac models with high amounts of RAM in a coup, especially for professional users who need all the memory possible on their computers. There are no Macs with a lot of RAM left, kid, only Maxibon A few hours ago, media like 9to5Mac and Macrumors They echoed the problem. If you went to Apple’s settings page and tried to purchase a Mac Mini or a mac studio with the largest amount of RAM available (64 GB and 256 GB respectively), the warning was not the one that usually appears on occasions of “it will take x weeks”, but rather a “not available”. That already made us suspect that something was wrong with the supply, but it is also not an isolated problem in the Apple Store in the United States. If right now we go to the Spanish page to configure either of the two Macs with the maximum amount of RAM, it directly sends the same message that it is not available. This goes beyond the classic “reserve and we ship it on a certain date”, it implies that Apple does not accept orders for those specific models. And it is not an anecdote. As pointed out MacRumorsa few weeks ago Apple quietly removed the option to configure Mac Studio with 512 GB, which already indicated that something was up. Other configurations had delivery times of one to five months, and the fact that both models cannot now be configured with the maximum versions of RAM suggests that they will probably also end up disappearing from the store. For most users, 16 and even 32 GB of RAM is more than enough, but those who configure a Mac Mini and Mac Studio model with 64 or 256 GB of RAM do so because it is necessary. It is no longer so much the extra price as it is knowing that that amount of RAM is needed for professional tasks, and eliminating the option (just when Apple has killed the Mac Pro) can be a problem for a niche of users who precisely need these features. For now, if we are going to configure a MacBook Pro, we can choose the maximum amount of RAM without a problem (beyond the longer waiting times than when there was no global supply problem), but in the background there is a much bigger problem. The estimates They point out that RAM producers will increase their production by 16% year-on-year, a figure very far from market needs. Analysts predict that this shortage will last until 2027 or 2028, but also there are more negative estimates They point to 2029 or 2030 to begin to see the market recovery. As soon as possible. And, although we focus on Apple because it is always the most striking case, we have already commented the case of the Steam Machine which cannot be launched because Valve does not have RAM… and there are more cases from manufacturers such as Dell, Lenovo or Asus turning to the Chinese market to be able to launch teams. Computex is one of the big annual events for PC manufacturers and is just around the corner in the middle of an unprecedented crisis. Because there is no RAM, there is no SSD, hard drives are in danger and even graphics cards are not secured. The truth is that it will be interesting to cover the event because the Manufacturers and sellers are going to have to juggle with the little that is available to them. And in Apple’s own upcoming calendar, we will have WWDC where, supposedly, there will be new professional processors. And, no matter how much there are new Apple Silicon, if these professionals cannot configure their computers with large amounts of RAM… it will not be worth much. It could also be a movement in anticipation of the renewal of the equipment, but they eliminated the 512 GB in March and now this is strange. In short, and as has been happening for months, everything is wrong with the RAM market.

We believed that data centers in space were a thing of the future. Kepler has already activated the largest orbital cluster

by

For years, talk of data centers in space sounded like the kind of idea that always seemed a few years away. The conversation existed, of course, but almost always supported by long-term plans, ambitious announcements and an industry that had not yet shown much real muscle in orbit. That is why what has just emerged deserves attention. TechCrunch explains that Kepler Communications has already launched the largest computing cluster currently operating in space, a sign that this race is beginning to leave the field of promise to enter, little by little, the field of infrastructure. What has Kepler put into orbit. It is not a large facility suspended above our heads, but rather a distributed cluster made up of 10 operational satellites. Together they add up to around 40 Nvidia Orin processors aimed at Edge Computingconnected to each other by laser links. That set, launched in January of this year, as we say, is today the largest active computing cluster in orbit. The company itself also frames this network as a constellation designed to move data in space almost in real time. What it really is. So we are not facing a massive orbital data center that replicates the Earth model, but rather a distributed architecture that combines connectivity and processing in the full space environment. This difference matters because it allows us to separate two plans that are often mixed: one thing is the large-scale vision defended by actors like SpaceX or Blue Origin, and quite another is this first step, much more attached to immediate uses and specific needs of missions in orbit. The immediate business. If this orbital computing is starting to be interesting, it is because it addresses a fairly clear problem: it does not always make sense to send all the data to Earth to process it later. The initial value of these systems is in working with the information right where it is generated, something especially useful for more advanced sensors and for applications that require a faster response. Kepler also maintains that its network can serve as a basis for future processing and connectivity services between different space assets, and the media adds that the company already transports and processes data uploaded from the ground, as well as information collected by payloads hosted on its own satellites. Sophia Space. Here a startup comes into the picture that wants to upload its proprietary operating system to one of the satellites in the constellation and try to deploy and configure it on six GPUs spread over two ships. In a terrestrial data center that would be almost routine, but it would be the first time we would see something like this in orbit. For Sophia, in addition, the test has a clear risk reduction value before its first launch scheduled for the end of 2027. And we are not talking about a minor detail: the company is developing space computers with passive cooling, a way with which it seeks to attack one of the big problems in this sector: avoiding overheating. Kepler doesn’t want to be that. In the midst of so much noise around orbital data centers, the company itself is trying to position itself in a somewhat different place on the map. Your corporate presentation insists in a mission much more linked to communications, with a hybrid optical constellation designed to modernize the flow of data in low orbit and beyond. In this sense, it does not define itself as a data center company, but as infrastructure for space applications. The journey has begun. If this step by Kepler makes anything clear, it is that orbital computing no longer belongs only to the realm of great presentations. SpaceX wants to deploy a massive network of satellites for AI, Google prepares in-orbit tests with solar-powered chips and Blue Origin has announced a constellation of more than 5,000 satellites. In parallel, starcloud already launched a satellite in 2025 with an Nvidia H100 GPU and Aetherflux targets 2027 for its first node.

Mexicans have been harassed by banks and financiers over the phone for years. Justice has just stopped their feet

by

In Mexico, debt collection by telephone has been part of the background noise for many people for years. Insistent calls, messages at odd hours and contacts that cross the line of reason have turned collection into one of those abuses that are often suffered before even understanding who should be responsible for them. For a long time, the pressure was concentrated on the office that dials or writes. But behind this harassment there is more than just an unknown number on the other end of the line: there is also a financial institution that hired him. The key resolution. The underlying novelty is not minor. On January 15, 2026, the Plenary Session of the Supreme Court of Justice of the Nation (SCJN) closed the door to one of the arguments with which some financial entities sought to release sanctions linked to their reports on collection offices. The ruling confirmed the validity of the framework that allows the CONDUSEF fine them when they fail to comply with these information obligations. According to the SCJN statement, in addition, there is a time limit to act: the authority has a maximum of 180 calendar days, counted from the expiration of the period granted for the hearing guarantee, to issue and notify the corresponding resolution. What this does change. The scope of the ruling goes beyond a technical discussion between courts and financial entities. The responsibility does not end with the firm that engages in improper practices, but can also reach the financial institution that hired it if it fails to comply with its reporting duties to the CONDUSEF. In other words, the entity can no longer hide so easily that the harassment was carried out by a third party. If you failed to report what the law requires, you may also be sanctioned. The origin of the fight. To understand why this case ended up in the Supreme Court, you have to go back to October 14, 2022. That day it was published in the DOF the Provision on Records before CONDUSEF, which established new obligations for financial institutions in their relationship with collection offices. Among other things, the rule obliged them to register these third parties with the Registry of Collection Offices and to submit reports on user complaints. The fines that came later were born precisely from that previous framework. The route the banks took. After the fines for non-compliance with these reports began, several financial entities chose to fight the matter in court. These resources moved between 2023 and 2025 until they ended up in the Amparo in Review 323/2025. In the case reviewed by the Supreme Court, the SCJN itself explained that the sanctioned entity alleged that the rules did not make it clear who was obliged to provide the information and that there were no clear time limits to sanction it. That was, in essence, the defense with which he tried to overturn the punishment. The Plenary’s response. The Supreme Court rejected the idea that these rules left financial institutions on uncertain ground. He assured that the framework that regulates reports on collection dispatches is clear and coherent, because it identifies the obligated subjects, establishes the charges that must be met and allows for precisely locating when there is non-compliance. For this reason, it concluded that the principles of typicity, reservation of law and legal certainty invoked by the entity that promoted the protection were not violated. What changes from now on. Rather than inaugurating a new rule, this ruling consolidates one that already existed and that had been challenged by financial entities. The difference is important, because based on this criterion it is much more difficult to maintain that there was not enough clarity to comply or to be sanctioned. In practical terms, the decision strengthens the position of CONDUSEF and makes it clearer that financial entities can also be administratively sanctioned when they fail to comply with the information obligations provided for by the regulation.

The more we calculate the size of the Universe, the less sense it all makes

by

We have known for a long time that the Universe is expanding. However, the speed at which it does so is a headache. Depending on which method is used to measure it, a different result is obtained. Now a much more precise way to measure it has finally been found, but it doesn’t really unravel much of the mess. It messes it up even more. An overlay of techniques. Through a superposition of different techniques, an international team of scientists has made the most precise calculation so far of the expansion speed of the Universe: 73.5 ± 0.81 kilometers per second per megaparsec. The figure coincides quite well with those that have been calculated in the past using data from the nearby Universe. However, it is quite far from what is calculated when data from the dawn of the Universe is used. This indicates that there is something in the physics of that furthest point in the cosmos that we have no idea about. Far from being solved, the mystery has become more complicated. A balloon that inflates. When we talk about the Universe expanding, we refer to the fact that galaxies are increasingly distant from each other. But not because the galaxies themselves move, but because the space between them widens. We can see it as a balloon on which a series of dots are painted. As the balloon inflates, the dots appear farther away, even though they have not moved from their place. Hubble voltage. Traditionally, the expansion rate of the Universe is calculated in two ways. Or by measuring the distances between stars and galaxies in the nearby Universe, or by measuring the cosmic microwave background. This is the electromagnetic radiation that remained as remnant of the Big Bang. That is, the oldest light that we can find in the Universe, since it was formed in the explosion with which it was formed. Therefore, the data is not taken from the nearby Universe, but from the most distant and ancient one, the one approaching the Big Bang. The figure obtained with both types of calculations should be the same. However, with the nearby Universe a speed of 73 kilometers per second per megaparsec is obtained, while with the most distant Universe a speed of 67 kilometers per second per megaparsec is calculated. This incoherence is known as Hubble tension. and indicates that, possibly, the Universe is expanding faster and faster. That’s why the closest one expands the fastest. This graph represents the tension that exists between measurements of the expansion rate of the late and nearby Universe, versus what would be expected based on measurements of the early Universe, specifically the cosmic microwave background. It could be a mistake. One of the hypotheses that seek to explain the Hubble tension is that, in reality, there is some error when measuring the expansion speed in the nearby Universe. There are many methods to calculate the distance between stars and galaxies and there could be an error. Therefore, an international team of scientists has decided to use a superposition of techniques to make a more precise calculation. Different types of stars. This method consists of simultaneously analyzing a large amount of data obtained from ground and space telescopes. These focus primarily on the brightness of Cepheid stars, red giants, supernovae, and galaxies of known brightness. The three types of stars mentioned are characterized by having a characteristic brightness, which is used to map the Universe and, therefore, also to calculate distances. With this superposition of techniques, the figure of 73.5 ± 0.81 kilometers per second per megaparsec was obtained. There is no mistake. When one of the superposition methods was eliminated, the alteration in the expansion rate of the Universe was minimal. The figure was practically the same. This indicates that the number has been measured perfectly. There is no mistake. So if the Hubble strain is not due to error, why does it occur? The mystery continues. After obtaining these results, the Hubble tension remains the prelude to a mystery. However, it is true that there are some hypotheses. For example, it is believed that the different figures in the distant and near Universe They may be due to the intervention of dark matter. There’s a lot we don’t know about her, so maybe it could explain what’s going on. On the other hand, there is the hypothesis that the Earth is in a place with spatial characteristics. It would be an area where there is relatively little matter, comparable to an air bubble in a cake. As explained in 2023 by one of the scientists who support this hypothesis, Indranil Banik“the density of matter is greater around the bubble, so gravitational forces emanate from this surrounding matter, attracting the galaxies in the bubble toward the edges of the cavity.” “That’s why they’re moving away from us faster than you would really expect.” Now we will have to solve that part of the mystery. At least we know that there is no error in the calculations and that the Hubble tension is a reality. Image | CTIO/NOIRLab/DOE/NSF/AURA/J.

We thought that quenching hunger with Ozempic was the definitive remedy against obesity. Until we look at the muscle

by

The revolution of drugs as they are OzempicWegovy or Mounjaro have undoubtedly marked a before and after in the approach to obesity, which previously went under the knife when measures focused on lifestyle changes failed. A priori, we are sold the idea of ​​having a very pronounced weight loss, but the reality is that many patients are falling into protein malnutrition and losing a large amount of muscle mass. We are getting more data. We do not know the drugs completely when they begin to be marketed, but as patients use them, they emerge. new side effects or situations that pharmaceutical companies had not initially imagined. Here a revealing new studywhich will be presented at the European Obesity Congress, has put figures on these effects of malnutrition that accompany successful treatments. And all this indicates that the strategy followed with Ozempic must be changed so that doctors can give precise indications of the nutritional strategy that must be followed during the treatment period to avoid serious health problems. Not having an appetite is bad. A priori, those who take Ozempic want to have less desire to eat, and for it to practically be a task that becomes an obligation in order to survive. But the problem is that people end up having too little hunger, as a new scientific study has shown. analyzed over 5,700 days of nutritional data of 332 overweight adults between July 2025 and 2026. What was seen. Of all of these, the 116 users who were taking drugs like Ozempic consumed drastically fewer calories than the control group, something that was quite expected, but the most important thing was the protein intake that plummeted when the drugs were taken. Specifically, medicated patients consumed an average of 53.8 grams of protein per day, and adjusted to their body weight, this amounts to just 0.6 g/kg/day. To put it in perspective, 88% of these patients fell well below the official recommendation of consuming 0.8 g/kg/day of protein, and far from optimal levels for preserving muscle during weight loss. The reason. Lack of hunger literally makes people skip meals, basically because they do not have that physiological need to put anything in their mouth. Here the study could see that patients taking Ozempic or similar skipped 40.4% of dinners, 31.3% of breakfasts and 30.5% of lunches. In this way, by reducing eating to a few moments of the day, it is almost impossible to achieve the around 25 grams of protein per meal that the body needs to synthesize new muscle and maintain the structure it has. It has consequences. In medicine, the fact of losing muscle mass is what is called sarcopenia and until now it was mainly associated with people who were not physically active, such as the elderly or those who were bedridden. Here scientific reviews suggest that between 25% and 40% of all the weight lost by users taking Ozempic is muscle. And in a very important proportion with respect to fat loss, making it so that almost for every two kilos of fat lost, one is muscle. In older adults or patients with type 2 diabetes, the situation is even more serious, since high doses of semaglutide accelerate sarcopenia, reducing vital metrics for longevity and quality of life, such as grip strength or walking speed. In addition, severe calorie restriction brings with it deficiencies of micronutrients such as vitamin D, vitamin B12 or iron. How to avoid it. Here, medical guidelines increasingly point to a personalized approach in which a highly nutritious diet is established to prevent the patient from having a macronutrient deficiency while losing weight. This is why it is already being recommended that during weight loss it is recommended to increase protein consumption from 1 to 1.6 grams of protein per kg of weight, prioritizing a minimum of 20-30 grams at each meal. In addition, a ban should be established on skipping meals, with eating times having to be very measured, even a little, but at different times throughout the day to avoid prolonged fasting. Maintain muscle. This should be the primary objective and that is why, along with a diet rich in protein, strength exercise with weights, bands or even calisthenics should be encouraged. In this way, the body has the signal to maintain the amount of muscle despite the fact that there is a loss of fat due to the medication. And here the objective is to lose weight, but without having to remove the bricks that are literally building our body, since if we manage to lose weight, but are left without muscle mass, the quality of life is not going to be the best.
