invisible

appears out of nowhere and turns Russia invisible

by

At the beginning of November a scene It went viral on networks. The arrival of Russian troops in Pokrovs was more typical of a dystopia, another example that the war in Ukraine seemed to have definitively become a mirror of what the war conflicts of the future will be like. Now we know that that scene was also the prelude to an advantage. The weather in front. Yes, on the eastern lines of Ukraine, the arrival of a winter full of dense fogs has transformed the battlefield in an unpredictable scenario where visibility, which previously determined the pace of drones, has become a strategic resource in itself. The veil of humidity that covers Donetsk, Zaporizhzhia and the approaches to Pokrovsk It makes the job of Ukrainian operators who rely on aerial surveillance to track Russian movements, but also offers an opportunity to sneak up, infiltrate and strike at close range. The chaos. In areas like Pokrovskwhere the lines overlap and the front is porous, the fog has caused a kind of calculated chaos that makes war unpredictable, a board where both armies move almost groping between bursts of fire that appear without warning, while the commanders admit that the weather is completely altering the reading of the terrain and the control of the approaches. Exploiting meteorological disorder. The fog has allowed Russian forces to promote specific advances and risky maneuvers. Taking advantage of the lack of aerial surveillance, mechanized units have managed to cross natural obstacles, build improvised bridges and make their way into areas where they were previously stopped by constant reconnaissance from the air. In southern regions, such as Zaporizhzhia and Dnipropetrovsklow visibility has coincided with an increase in assaults and intensive bombing that has forced Ukraine to retreat from certain positions in search of more sustainable defensive lines. The accumulation of troops under the cover of fog, the concentration of armored vehicles and the constant infiltrations by small teams seeking to advance without being detected reflect a strategy that combines quantity, continuous pressure and meteorological opportunism. At the same time, the movement of columns towards towns such as Huliaipole and Yablukove confirms that Russia tries to convert each weather window into a territorial advance, aware that controlling logistics nodes at this time of year can set the trend for the entire campaign. Solution: ground robots. Faced with the temporary loss of eyes in the sky, Ukraine has begun to integrate ground robotic systems to replace the surveillance that drones previously guaranteed. The appearance of UGVs In the defense of Pokrovsk it has made it possible to detect enemy movements that would have gone unnoticed in the dense fog and has served to guide subsequent attacks with FPV drones when visibility permitted. These small, discreet and fast platforms have provided an additional layer reconnaissance in areas where even the best aerial optics fail. Its deployment shows that the Ukrainian army is maturing hybrid doctrines where ground robots complete the work of drones that they previously dominated alone. If you will, it’s a preview of how technological warfare could evolve in the coming years: closer integration between autonomous ground sensors and aerial vectors, especially in adverse climates that are becoming more frequent and extreme. Units operating in Pokrovsk describe combat scenes where attacks emerge from the fogguided by machines that detect heat, sound or movement in conditions in which the human eye is practically blind. The pressure on Pokrovsk. The worsening of the weather coincides with a deterioration of the tactical situation in Pokrovska critical point due to its value as a transport hub and link for the defense of the east. Russia has intensified assaults relying both on climate coverage and on a notable numerical imbalance that favors its troops. Ukrainian forces acknowledge that they face waves of infantry in very small groups, teams of two or three soldiers seeking to saturate the defenses through multiple approaches, and that the fog has facilitated the temporary return of mechanized assaultseven using civilian vehicles to advance quickly in the direction of the city. A plan B. This dynamic has forced Ukraine to combine tactical withdrawals, civilian evacuations and robotic ground reconnaissance to avoid surprises. The adverse weather has accelerated the feeling of uncertainty on a front where every meter of ground is contested blindly and where the lack of aerial vision multiplies the risk that an enemy leak becomes an operational rupture. Time changes everything. The combination of persistent fog, limited mobility and low visibility has created a combat ecosystem that rewards both creativity and audacity. In this environment, the infiltration tactics Russians find more room to thrive, but so do quick Ukrainian incursions that seek to disorient the adversary in the chaos of the fog. Climate has become a multiplier of uncertainty: it degrades the precision of drones, distorts sensors, creates gaps in surveillance and pushes both sides to improvise technological and tactical solutions. Ukrainian ground robots represent a popup response to those conditions, while Russian advances under adverse weather show the importance Moscow attaches at any opportunity to break the Ukrainian defense.

a poncho turns its soldiers in Ukraine into an invisible army

by

Last October Ukraine I remembered to his troops that Russian soldiers had come up with a new infiltration system. After the helmets with antennathe lures and the optical illusionsMoscow had found a way to appear among the Ukrainian forces “out of nowhere”. Now, in a new unprecedented twist in the conflict, Russia has found the closest thing to an invisibility shield. From the video game to the fight. Something very similar to what we saw in the Metal Gear saga, then called optical camouflagehas appeared in the conflict in Europe. The war on the Russian-Ukrainian front has seen a tactical evolution that has shifted classic protection (armor and vehicles) towards mobility and thermal stealth: Russian assault forces have adopted ponchos or thermal tarps (the so-called “invisibility cloaks”) as an essential element to minimize the infrared signature and allow infiltrations on foot in the wide swath controlled by the drones. There is no perfect thermal concealment, but the difference between being detected or not can decide the life of an assault group. That’s why these clothes, combined with night movements and the use of specific environmental conditions, have become a central tactical tool that, in practice, today protects more than many armored vehicles against the aerial threat of reconnaissance and attack. Tactical evolution. Thermal tarps are blankets made with reflective layers and materials that accelerate heat dissipation, their purpose is approximate the temperature superficial of the human body to that of the environment to reduce contrast that thermal cameras detect. However, its effectiveness depends of multiple factors: quality of the material, contour sealing (bare feet and hands are detectable signs), weather conditions and, above all, the time of day. The so-called as “thermal crossover” (two brief daily periods in which vegetation, soil and air have similar temperatures) reduces global thermal contrast and offers the optimal window to move forward without standing out, while fog, rain or humidity can complement that invisibility. Improperly used, ponchos generate “cold spots” that attract attentionbut used well, multiply the probability of achieving tactical objectives. Limitations and learning. It must be clarified that thermal tarps do not make the attacker invulnerable. Experienced drone operators look for subtle signs (bare feet, movement under the cover, small thermal disturbances) and learn to distinguish behavioral patterns that reveal infiltrations. In addition, there are low quality materials and training errors: there are cases of soldiers who tried to camouflage themselves in broad daylight or with inappropriate ponchos and were detected. The tactic is therefore effective but fragile: it works best en masse, under optimal conditions and when the adversary lacks sufficient alternative sensors or personnel on the line. US Marine Corps uniform with built-in thermal camouflage Countermeasures and tactical recovery. To counteract these infiltrations, the solution it is not unique: involves deploying complementary sensors (acoustic, magnetic, seismic) that do not depend on the thermal spectrum, or reinforcing minefields and physical barriers, densifying human or robotic presence in exposed sectors, or even improving doctrine multisensory surveillance and train detection teams to identify minimal signs of intrusion. In strategic terms, Ukrainian forces agree that the response involves combining technology (more sensors, better integration) with greater territorial occupation, because passive defense based solely in aerial interceptions It is insufficient against equipment that infiltrates at low visibility. Operational implications. The resort to small infiltrated groups reflects broader tensions: troop shortages, accumulated material wear and tear, and an environment where air or drone superiority does not guarantee the security of the rear. For those who attack, the tactics allows you to exploit holes in defense and wear down positions through groups that, although they lose part of their troops, can complete reconnaissance, sabotage or local assault missions. For those who defend it, it forces us to rethink the segmentation of the front and the provision of resources: the balance between expensive sensors and effective personnel, the need for mobile reserves and the growing importance of passive and active containment measures on the ground. Strategic conclusion. If you like, we are facing a tactical transformation where war becomes more granular and less dependent on traditional armor: the multiplication of drones and sensors has revalued thermal invisibility and human mobility, while it has revealed the fragility of conventional defensive schemes. In the short term, the balance favors those who know integrate camouflagemeteorology and discreet logistics. In the medium term, effective defense will require a greater density of heterogeneous sensors, more troops or robotic means on the line and a doctrinal adaptation that combines multisensory detection with physical measures that close the gaps that infiltrators exploit today. In short, in the current field a thermal tarpwell used, can offer an attacker more practical protection than many armored vehicles, and this realization forces us to rethink tactical defense and territory management in a conflict dominated by sensor warfare.

We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot

by

Recognize it: if you are old enough to have played withA Light GunFor a while you thought that this gadget worked by firing rays of invisible light that television detected. Was it the position of the gun? The distance? Did the glass of the screen really knew when the goal was in front? Actually the solution was much simpler and ingenious. The light ray is in reverse: the gun is the receiver. Guns of what. First, let’s remember the history of the device: the light guns in video games began to appear in the thirties in mechanical arcades and evolved towards electronic video games in the 1970s and 1980s. Nintendo already experimented with early versions with its video shooting series for famicom in 1984, whose gun was not futuristic, but it seemed like a western revolver With the theme of the game. Nintendo arrives. The device of this most popular type was Nintendo Zapper for Nespossibly because he was accompanied by one of the most iconic games of the genre, ‘Duck hunt’. The Zapper was already tumbos since 1984 with the version for Famicom, but in 1985 it became the Zapper of NES and left in the United States with the science fiction design we know, automatically becoming a pop icon. In 1988 it was redesigned with bright colors to resemble even less to a real weapon and comply with the legislation. There were up to 17 official games for Zapper. In Xataka This genius has transformed the ZNA Zapper is an incredible laser ray gun But … how did it work? Actually the Zapper and the rest of the light guns of the time were not emitters, but light receptors. The process that followed to work was: when the player clenched a trigger, the screen turned black during a Frame. In the following, the objects to which they have to become white blocks, and the rest remains black. The human eye can barely distinguish this pair of Frames Inside the gun was a light sensor that detected if the area to which it was aimed had changed to Blanco. The game determined what objective had been “shot” according to the time in which this white block appeared, since each white objective was sequentially shown in a different frame. And of course, if the sensor detected the white light inside the expected interval, the shot was counted as a success. Only for old people. The ingenious method only worked on CRT screens, as technology depended completely on the speed and characteristics (on the shortcomings, let’s go) on the soda speed of the cathodic tube. On LCD screens, plasmas and other modernities, the delay changes, and so does the soda technology. What makes ancient games “rare” on modern televisions is also what prevents the gun sensor from correctly capturing the light and location of whites. {“Videid”: “X9HMC3A”, “Autoplay”: False, “Title”: “Nes Mini, Review and Spanish analysis”, “Tag”: “”, “Duration”: “250”} More guns. Then, especially in the field of recreational, more sophisticated guns arrived, such as ‘Operation Wolf’, which was actually a command that determined where it pointed according to the position of the gun, fixed in the machine of the machine (a method as ingenious as that of the Zapper, playing with what the player who is happening is believed). And then they arrived, in fact they do in machines that remain in operation, increasingly sophisticated systems, and that use infrared sensors or cameras to determine where the player points out. But the adorable imagination and naivety of the Zapper give him a unique personality. In Xataka | The Nintendo PlayStation exists: this is the history of the hybrid console that never reached the market (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot It was originally posted in Xataka by John Tones .

LG has created a “invisible” aspirator robot. It is saved under the sink, it makes little noise and keeps the mopa always ready

by

Aspiring robots have become regular household partners. They have gone from being a technological whim to a practical tool that avoids spending hours to cleaning. However, as we get used to them, we have also begun to demand more: It is not enough that they aspire wellwe want them to do it without interrupting our routine, without occupying space or generating noise. The real comfort is that they work without us just perceiving them. In this scenario it appears LG’s last proposalthought precisely to make that jump. A model that not only seeks to fulfill the task of cleaning, but to do it in the most discreet way possible. The concept is not to add more buttons or striking functions, but in reducing its presence at home, to the point of becoming almost invisible to the user’s eyes. Technology that cleans and disappears from the visual map The South Korean firm will present at the IFA 2025 fair an aspirator robot that moves away from the conventional. Instead of settling in a visible base in the middle of the room, Your station hides under the sinkoccupying a space so far wasted in many kitchens. With a design designed to go unnoticed, it is integrated into the domestic environment without altering aesthetics or requiring additional surfaces. We are facing a proposal that not only seeks discretion, also comfort. The station door opens and closes automatically so that the robot can enter and leave without user intervention. In this way, the cleaning experience becomes completely hands -free, in a line other than that of other vacuum cleaners that continue to depend on voluminous stations in sight. Beyond its hidden location, the robot incorporates technical improvements designed to optimize cleaning. According to LG information, it integrates an artificial intelligence chip that allows you to recognize furniture, objects and areas with dirt, which translates into a more precise navigation and adapted to the environment. It also has a system that detects carpets and automatically orders return to the station to detach the mopa, avoiding unwanted spots on textile surfaces. The station, with discreet appearance, also plays an active role in maintenance. Not only loads the device, it also sterilizes the mop with hot water and steam after each use, reducing odors and guaranteeing constant hygiene. With this, the South Korean company seeks that the user does not have to perform additional tasks and that the feeling of cleaning is maintained at all times. Although the proposal is attractive, there are still important questions. LG has not revealed the commercial name of the model, or its price, nor the availability date in Spain. Nor has it detailed essential technical aspects, such as suction capacity or battery autonomy, data that usually make a difference when choosing between one vacuum or another. The South Korean company has preferred to reserve that information for later, within the framework of the IFA 2025 fair, which is held in Berlin from September 5 to 9. Until then, what is known is rather a declaration of intentions: an approach oriented to practicality and discretion, with the challenge of demonstrating in practice that may be up to its rivals. LG’s challenge is not less, because it enters In a field with consolidated actors. Brands like Irobot, with the Roba Max 705They have opted to facilitate cleaning in households with pets. Roborock, with Saros Z70has taken an innovative step by integrating a robotic arm that expands the extent of cleaning. And dreame me, with the Aqua10 Ultra Roller Completeit focuses on solving one of the usual weaknesses of these devices: the maintenance of the mop. The commitment to a robot that practically disappears seeks to differentiate LG in this competitive scenario. It is not just about offering an effective product, but about convincing users that discreet integration and minimum maintenance are added values ​​in front of a very varied catalog. The LG approach fits with a clear trend: we want technology to do its job without interrupting us. Aspiring robots had already earned a place at home, but this movement points to a new level of integration. A device that automatically cleanshe stays ready by himself and is barely seen. It remains to be seen if the real performance accompanies the promise. Images | LG In Xataka | DREame H15 Mix, Analysis: If I could only buy a vacuum cleaner to clean everything, it would be this

The startup that capitalizes our fear of an invisible enemy

The places where we can find microplastics grow as time passes. We have already detected them in Testicles, lettuce, at seathe breast milk either even in the air. Taking advantage of this growing concern for this pollutant, there is a London company that is selling an ‘innovative’ therapy: clean the blood of microplastics in exchange for a payment of 11,500 euros the session. It is not yet known if microplastics are in the blood. Today, microplastics have been found in many parts of our body, but the fact that they are circulating in the blood is something that today is not serious for our health. Although companies have seen the opportunity to create a great business around health and this pollutant. A luxury treatment in the heart of London. In the prestigious Harley Street, known for its private clinics and its wealthy clientele, between 10 and 15 people a week they sit on a comfortable armchair to undergo the treatment of the company Clarify Clinics. The procedure, which lasts about two hours, resembles a dialysis session. Although previously we have to pay 9,750 pounds, which would be around 11,500 euros. Something that the big stars pay such as Orlando Bloom. A cannula extract the patient’s blood and introduces it into a machine that separates the plasma from red blood cells. This plasma passes through a filter designed to catch microplastics and other pollutants such as perfluoroalized and polyfluoralized substances. Once the blood is ‘clean’, the plasma is recombine with blood cells and reintroduced into the body. So comfortable that you can work during therapy. In his attempt to attract more and more patients, CEO of Clarify Clinic points out that it is a “very comfortable” technique According to Wired. So comfortable is that he acknowledges that patients make calls, gather by zoom or even watch a movie while their blood is cleaned. Indicated for patients with nonspecific symptoms. According to the company itself, customers who go to their clinic share chronic fatigue or ‘mental fog’. Although the clinic also promotes its treatments for people who take medications to lose weight such as Ozempic, couples seeking to conceive or those concerned about dementia. The result is always the same: they come out as new. Science is not clear. The scientific community has shown that microplastics are literally surrounding us. But there is no evidence of its effects on the body. WHO itselfin a report published in 2019, he concluded that there is still not enough evidence to determine if they suppose a risk to human health. We do not know if they are safe, but we also do not know the risks they could raise to create specific therapies to ‘detoxify ourselves’. If we go to the website of this clinicthe truth is that available from a section called ‘Science’. But upon entering it offers many data, but few references (if not any) of research that speak of the effects on the health of microplastics. They are limited to what we know: their presence in numerous places. But, on the other hand, they point out that they eliminate all the effects of this pollutant. More research is still needed. Although some studies have found worrying correlations, causality remains very elusive. A 2022 review associated microplastics with damage to human cells in the laboratory, but did not examine health results in living people. More recently, In a study Published in the prestigious magazine New England He found that people with microplastics in the fatty plaque of their carotid arteries had a higher risk of heart attack and cardiovascular accident. However, the study was observational and could not prove that microplastics will cause That greatest risk. There could be other factors: patients with microplastics in their arteries were also more likely to be men, smokers and to have pre -existing cardiovascular diseases. A anecdotal -based therapy. Although the evidence is very small, the CEO of Clarify Clinics sells its therapy as a miraculous thanks to the effects it has on its patients. It points to the fact that higher levels of energy or better sleep are reported, and even herself monitors her dream with The oura ring And he assures that after the treatment, his sleep score has not dropped from 90, when before 70 was a good result for her. Biohacking for rich: a booming trend. Microplastic blood cleaning joins a growing list of high -coastal treatments and with doubtful scientific evidence. From the injections of stem cells in Bahamasuntil Receive a child’s plasma injection To stay young. And in many cases these treatments have a common goal: to stay young. And for this there are many people who They can invest millions of dollars in therapies. Our obsession with this objective makes even investigations are pointing to medications that reverse human agingalthough without thinking about the consequences you have.

China already has its “invisible hunt” ready for action, and twice

by

There is no official announcement. But China leaves clues again. This time they arrive from a Photography published in Weibo and replicated in x: two J-35 They fly in closed formation. What differentiates them from the prototypes seen so far are their construction numbers, “0011” and “0012”, clearly visible in the fuselage. It is a solid indication that the program has entered a limited series production phase, the typical LRIP prior to the operational deployment. LRIP registrations, emblems and a shark in the tail. The image seems to come from an official channel of the Chinese Navy. To the numbers are added other details that reinforce the hypothesis: national emblems in the vertical fins, a tactical gray free and a reason for a shark in drift. The specialist Andreas Ruprecht, Consulted by specialized means like War Zonehas repeatedly indicated these visual winks in Chinese naval aircraft. Click to see the publication in x The pilots also give clues: they carry bright blue helmets, exactly the type of helmet used by J-15 aviators in first-line units. All this suggests that these J-35 are already assigned to the Navy and in the validation phase prior to their entry into service. From FC-31 to J-35: the navalized variant that China needed. The J-35 derives from the FC-31, Shenyang’s furtive project for a more compact hunt than the J-20. The first navalized prototype flew in 2021; The second was seen in 2022 with a gray gray scheme of low visibility and, in 2023, blurred images of what could have been a third device emerged. Now, with the 0011 and 0012 specimens, we talk about units that already fit an initial serial configuration. The design is designed to operate from carckeners with catapults, such as Type 003 Fujianeven in tests. It is the logical step in an army that has been training in land facilities that simulates Catobar covers for years. Motors: WS-19 against WS-21, a puzzle still unsolved. The motor plant is still unknown. Some suggest that the land version, J-35a, already mounts the final WS-19, identifiable by darker nozzles. On the other hand, the naval specimens, with clear nozzles, could be driven by the WS-21, an evolution of the WS-13 used in the initial prototypes. There is no official confirmation and it is likely that Shenyang continues to adjust the engines in parallel to the progress of the program. Both airplanes carry a screwed Luneburg lens under their belly, a radar reflector that is installed when no total observability is required or when you want to mask the real firm of the device before third parties. Tests on aircraft carrier? For now there are no photos that demonstrate it. With airplanes apparently already in the hands of the Navy, the embarked essays are the next logical step if they have not already begun. There is also talk of a possible public presentation in September, during the acts by the 80th anniversary of the Japanese defeat in World War II. We will have to see if Beijing takes that occasion to exhibit it. One more piece in the puzzle of Chinese embarked air power. The J-35 adds to the KJ-600 early alert embarked the poaches that China has in development. Everything indicates that the country wants a more complex shipped air wing and comparable to that of the United States. It must know how long it will take to achieve real operational capabilities with this new generation of platforms.

We have been confusing celiachy and gluten intolerance for years. The difference is important but invisible to the naked eye

by

In recent years we have seen that celiacía or celiac disease and gluten intolerances They were visible. Although today society is more familiar with these terms, the fact that the element that unleashes both adverse reactions of our body is the same, gluten, implies possible confusion between one disorder and another. Let’s start with the basics: What is gluten. Gluten is a protein that we can find in the grains of some plants, among which we can highlight wheat, rye or barley. Gluten can even be extracted and used as an additive to give some texture and flavor. However, in the supermarket we will also find products that highlight in its packaging the absence of this protein. The reason is that many people feel adverse reactions to their consumption. These reactions have different origins but similar symptoms, which makes many people not familiar with the differences between these two disorders. Celiacy It is an autoimmune disorder. When celiac people consume buttocks, their immune system is unleashed and damages intestinal villi. These are microscopic projections that are part internal lining of the intestine, fundamental when absorbing nutrients. The damage caused hinders precisely the absorption of nutrients after the autoimmune reaction is unleashed. We do not know of the existence of a cure for this disease and it is little that we know of its origin. We do know that there is a hereditary component: people with celiac relatives are more likely to suffer from this disorder. Among its symptoms, abdominal pain, gases, constipation, apparently inexplicable weight loss, among others, can be found. Gluten intolerance, gluten sensitivity or Non -celiac gluten sensitivity (NCGS) is also unleashed as a reaction to gluten consumption and presents some similar symptoms to celiac disease. However, in these cases, experts are not clear about the intervention of the immune system because antibodies are not detected in our body’s response to protein consumption. This adverse reaction can also make symptoms arise in our digestive system, including gases, diarrhea or constipation; as well as symptoms of other types such as headache, joint pain or rashes. Little by little we study this type of problem, but there is still little we know about this intolerance. Similarities and differences The fundamental difference between gluten and celiacan intolerance is what makes the latter a more serious disorder, and it is the damage that appears in the intestine and that can affect how our body absorbs our body nutrients. This damage does not occur in intolerant people. He Autoimmune origin It can also be seen as an important difference. Both disorders share some symptoms but it is also important to cut the gluten of diets also leads to a rapid improvement of these symptoms. So how is each condition diagnosed? When we feel that gluten feels bad for us We can submit to some tests that tell us if we have celiacy. A Antibody test You can tell us if our body is generating an autoimmune reaction by processing gluten. We can also make a genetic test that tells us if our genes are related to a propensity to suffering from the disease. Finally, a biopsy can indicate if we present intestinal lesions of celiacism. If the tests do not indicate the probability that we suffer from this disease but our symptoms refer by ceasing to consume gluten, it is likely that the diagnosis is NGCS. “Celiac disease is a disorder of the immune system that damages your small intestine even when you eat a small amount of gluten. Celiachy also runs in the blood,” Explain Alberto Rubio Tapiaof the Cleveland Clinic. “(Non -celiac gluten sensitivity) is a digestive disorder, not an immune system problem. NGCS does not damage your intestine and does not tend to repeat itself in families.” As if this were not enough, there is another disorder that can sometimes lead us to confusion. Celiacía and intolerance should not be confused with food allergiesespecially with the Wheat allergy. Being wheat, an important gluten source, falling into this error can be easy. A not very severe food allergy can cause similar symptoms that could be confused with those of celiac disease or with gluten intolerance. Other symptoms of allergies, such as itching in the eyes or respiratory problems can help us distinguish this third problem. Distinguishing between the three conditions is more important than it seems. The most severe food allergies can put our lives at risk, but celiachy is also related to serious health problems that can occur in the long term. Celiac people tend for example to present a Greater risk of suffering from intestinal cancer, lactose intolerance or type I diabetes.

It will not be “invisible” but much more maneuverable

by

Chance wanted that in the midst of controversy over the ability of the United States to disable your F-35 At a distance one of the most important and expected ads arises by the military industry. Washington lifted the curtain and show what I had been developing for a while From the hand of Boeing, the F-47 for replace Raptor He made an appearance with a word above the rest: furtive. However, ailerons betray much more of the combat plane. The canards and the revealing signal. Yesterday we talk about the Presentation of F-47the plane chosen as a axis of the program Next Generation Air Dominance (Ngad) of the United States Air Force. The announcement has generated An intense debate Due to a surprising detail in its official renders: inclusion of Canards (Front spoils). This trait, more common in fourth generation fighters such as The rafale either The flucollides with Previous expectations of a design almost exclusively focused on stealth, scope, load and speed, leaving aside maneuverability as a priority. His presence suggests that Boeing has taken a turn to a more agile design, possibly for different tactical purposes, or even betting on a complete reinterpretation of operational needs of the ngad. This element, although apparently lower, opens multiple questions about the decisions hidden behind the project and the strategic priorities that the USAF is adopting against the future of air combat. Vs. vs. spoilers. To understand the intense debate, it should be clarified that the canards grant greater maneuverability and stability, especially in aircraft with Wings in Delta and without rear stabilizers, but they have traditionally been avoided in poacted fighters due front radar signalcritic for survival in hostile environments. In other words: this inclusion of control surfaces seem to conflict with those public objectives of Vray Low Observability (VLO) or Multibanda, a standard that seeks invisibility to multiple types of radar, not just fire control. Referents. Impossible not to remember aircraft Like the B-21 Raiderdesigned with this principle as axis, unlike platforms that, such as The Chinese J-20have been criticized for incorporating canards and compromise their stealth. What does all this mean? As they pointed out The War Zone analyststhe F-47 could be betting on new technological solutions to counteract that effectsuch as advanced composite materials, geometries that deviate radar signals or even morphological structures capable of modifying their shape in flight. However, it is still uncertain if these measures are enough to conserve a high level of raim against increasingly sophisticated threats. The B21 Raider Modular hunting or new tactical vision? Another possibility is that the F-47 has been conceived as A modular platform with different configurations for different operational theaters. Under this prism, initially contemplated in the NGAD program (although it was then said that it was abandoned), it consisted of a short -range variant and greater agility for Europe, and another long range for the Pacific. The Canards. The appearance of the Canards could point to a rebirth of said strategy, or at least, to a flexibility in stealth requirements in exchange for Other tactical capacitiesas take -off on short tracks, efficiency in agile combat environments or more effective integration with Non -manned aircraft. Plus: To this is added the possibility that the F-47 has a more compact size and a more traditional design oriented, delegating functions such as surveillance, remote attack or electronic war to allied drones (Collaborative Combat Aircraftor CCA), which would allow, a priori, reduce costs, simplify the aircraft and increase the number of units produced. Pragmatism against vulnerabilities. The turn towards a more conventional design, with less autonomy and greater maneuverability, could also respond to a pragmatic reassessment of resources and threats. USAF recognized that its dependence on Tankers represents A crucial weaknessespecially before an adversary like China, capable of blocking aerial replenishment routes. In that context, a long -range hunting would make more strategic sense. However, opt for a more accessible platform, accompanied by the development of A furtive tank plane (NGAS), it could have been a more or less acceptable commitment: less scope and load in exchange for a more versatile and economically sustainable ecosystem. He NGAD program It was paused in 2023 precisely to evaluate these types of decisions, in a context of budgetary restrictions and emerging technological threats. The choice of F-47, and its promise to be more reliable, furtive and exportable than its predecessors, aims to be the result of that strategic readjustment (and, obvious, to be a “Super Survents“). Uncertain future. For everything described, the F-47 represents a visual and conceptual breakup regarding what was expected of An NGAD hunt. As we said, instead of the traditional delta design without a large tail and ultrafurtive profile, the renders show a more compact fuselage, wings with a positive dihedral, shovel -shaped nose and those enigmatic Canards. The result reminds previous experiments such as Bird of Preyhe X-36 or even to Qaher 313 Iranian, that refined concepts of F-22 or of the B-21. Of course, it is soon to draw definitive conclusions, the fact that the F-47 has been described as an aircraft that will occur In large quantitieswhich will be exported to allies and that will have greater autonomy and maintenance as the current fighters, indicates that we are facing a hybrid solution between the aspirational and the pragmatic. The great unknown lies in how much stealth, scope and capacity has been sacrificed to achieve that balance. Image | USAF, Northrop Grumman In Xataka | Boeing came from difficult years.

ASML’s “invisible monopoly” is indisputable. Although without the technology of these companies would not have reached the top

“In 1997, Jos Benschop, the leader of the Investigation Department of ASMLreassess whether extreme ultraviolet technology (UVE) was a viable option. After the first tests he realized that Zeiss was able to develop extraordinarily sophisticated mirrors that would be necessary to transport ultraviolet light. Everything began to change: The puzzle pieces began to fit in their holes and that impossible machine was acquiring little by little. ” These lines come from the chapter entitled “An invisible monopoly” from the very interesting trial book “Focus: The Asml Way” written by Dutch journalist Marc Hijink. We have resorted to them to open this text for a weight reason: they perfectly condense the complexity of the lithography machine that has allowed ASML to lead the industry of the manufacturing equipment of chips alone. And it is that Europe has a voice in the integrated circuit industry thanks to this company of the Netherlands. ASML has no competition since its first UVE photolithography team placed on the market. Japanese Canon and Nikon companies, their natural competitors, also tried to develop this machine, but failed in the attempt. The technical and economic resources that were necessary to make it possible were so numerous that They decided to retire from the struggle with Asml. Free road. Today the most advanced semiconductor manufacturing machines that we can find in the TSMC, Intel, Samsung or SK Hynix plants produce ASML. Currently his reign seems imperturbable. Canon has developed a team of nano -impression lithography that it seeks to compete from you to you with the UVE machines of ASML, but for the moment it is not clear that this technology will be able to rival the most advanced team of the Dutch company: the machine of High Opening Photolithography (UVE). Intel is already testing it, and it is expected that TSMC and Samsung do so for the next few months. Presumably thanks to it they can produce chips of less than 1 nm before this decade expires. ASML does not walk alone UVE photolithography equipment is extraordinarily sophisticated. The GPUs for artificial intelligence more advanced from Nvidia; The most powerful soc that Apple or the CPUs with the highest AMD performance are possible thanks to them. Of course, none of these companies make their own chips. They design them, but they are produced by the Taiwanese company TSMC using ASML UVE lithography machines. However, this European Corporation has not developed solo all innovations that have made its most advanced integrated circuit production equipment possible. One of its most important allies is the American company Cymer. This company founded in 1986 specializes in the manufacture of lasers and deep ultraviolet light sources (UVP) and extreme (UVE). It has a very close relationship with ASML for many years; In fact, the role that Cymer manufactures in lithography machines is so relevant than in 2013 ASML bought this San Diego company with the purpose of investing in it to accelerate the development of the technologies involved in UVE lithography. The ultraviolet light transports the geometric pattern described by the mask to the surface of the Silicio wafer Somehow Cymer gives ASML the raw material that their photolithography machines need. And that raw material is none other than the ultraviolet light that is responsible for transporting the geometric pattern described by the mask so that it can be transferred with great precision to the surface of the Silicon wafer. Understanding what is the mask is simple: it is nothing other than a physical template that contains the design of the integrated circuit that is necessary to transfer to the Silicon wafer. During this transfer process a fine sheet of a substance sensitive to ultraviolet light is placed on the wafer and exposes the latter. The mask blocks or allows the passage of light in concrete regions of the wafer, thus transferring the chip pattern. Then the development, engraving and deposition processes follow each other whose purpose is, in broad strokes, transfer the different layers of the circuit integrated to the wafer and consolidate the transistors and interconnections that shape the chip. Interestingly, as we have just seen, the photolithography process is very similar to the chemical development of photographs. Of course, it is much more complex and requires working with resolutions that until a few years ago were unimaginable. Precisely thanks to the very high resolution with which it is possible to transfer the geometric pattern that describes the circuit integrated to the wafer today we enjoy Integrated 3 Nm circuits. And for 2025 they will be available The first 2 Nm semiconductors. Since we are involved in flour, it is worth investigating a little more in the characteristics of the light used by UVE lithography equipment. And its most striking property is that it belongs to the most energy portion of the ultraviolet region of the electromagnetic spectrum. In fact, its wavelength extends in the range that goes From 10 to 100 nanometers (NM). The problem is that it is not easy to generate and deal with this form of electromagnetic radiation. And it is not, among other reasons, because it is so energetic that it alters the structure of the physical elements with which it interacts inside the lithography machine. In addition, the UVE light must travel from the source to the silicon wafer without interacting with the slightest dust particle, so it is necessary that the entire chips production process be carried out inside a camera designed to provide a very quality vacuum. Anyway, the transport of ultraviolet light from the fountain that produces it to the wafer is only possible thanks to the intervention of the mirrors that the other great ally of ASML designs and manufactures: the German company Zeiss. If the mirrors involved in the propagation of the UVE light are not manufactured with enormous precision the geometric pattern defined by the mask will be altered The role of Zeiss’s optical elements in these lithography equipment is crucial. And it is because they are responsible, … Read more

It is not infallible, but we have a trick to protect the mobile against invisible malware: a reset on time

by

Putting the shoot after the wound is not optimal, but it is something we usually do in the digital world. When our accounts or passwords – or those of someone close – are violated, is when we start worrying about cybersecurity. We change the passwordsWe add Two -step verification systems And we see what we can do so that Our accounts and devices are safer. And, between All types of malwarethere is a tremendously annoying and dangerous one: the spy software that performs Zero-Click attacks. The good thing is that we can protect ourselves by acquiring a simple habit: restart the mobile. Zero click. When we talk about such vulnerability, we refer to a security failure that allows someone to enter malicious software on our device without having to perform any action. Taking advantage of a mobile safety failure or PCs, hackers are capable of ‘strain’ software on the device without having downloaded anything or punctured in strange links. That is why it is called ‘Zero Click’, since, to open the doors of our device to another type of malware -like phishing, for example -we do have to perform an action. This is something that has been used recently in apps such as Outlook or in him iPhoneand the same thing always happens: failures in the safety of the app or the system opens the door torque to the click zero malware. Pegasus. These vulnerabilities usually occur the same day to launch a new version of an app or an operating system. Taking advantage of possible programming failures and safety gaps, malware can go through a back door without us knowing. And these attacks usually go hand in hand with spy software, very difficult to identify by the user, but that has almost ease access for our device. Surely sounds to you Pegasusthat spy software developed by the Israeli company that He infected mobiles of thousands of journalists, politicians and other personalities. Using capacities similar To those who attack taking advantage of the Zero-Click, it allows to see, even, conversations in encrypted apps. Through WhatsApp. But it is not the only one, since recently, spy software known as Graphite infected the mobile of several people using a WhatsApp failure. Rocky Cole is the co -founder of a cybersecurity company and has commented A ZDNET that Graphite sneaked into the mobile through an image or a PDF sent by WhatsApp To the mobile of the victims, and the underlying processes that are activated when files are received in the app are the ones that the attackers explode to infect the device. It is not known, at least publicly, if Graphite can move to the core of iOS or only operate on WhatsApp, but could take advantage of an “escalation of privileges” – a vulnerability of the app – to move outside the messaging application. Cole states that this attack was aimed at concrete people, but comments that it is an emerging threat to all. “And the world is not, at all, prepared to deal with something like that,” he says. Tract it as a computer. In the report, Cole leaves the wedge of the advertising of its application Iverify, but also two tips that are not unknown, but it is worth remembering. The first is that we should acquire the habit of restarting or off the mobile every day. The reason is that many of these vulnerabilities exist only in memory and, not being files, in theory the malware should be eliminated when cleaning the memory after a restart. The bad thing is that it is easy for the spy software to return to the device, so something that it also recommends is to install the updates as soon as they are available. These patches usually cover the vulnerabilities found by both companies and external groups, such as Mozilla Security Groupwho analyzes the software and warns those responsible to patch it. Better turn off. Although several security experts agree that we should not leave the mobile on 24/7, not everyone agrees that a simple restart can solve these problems. The reason is that, when restarting the device, some mobiles try to maintain everything as it was before, storing certain data in memory and these being the ones that would take advantage of the hackers. The NSA – the United States National Security Agency – commented that It is best to turn it off completely and wait a few seconds before turning it on again. In this way, all applications have to start from scratch again. And, according to the NSA, it is something we should do once a week. Beyond security. The NSA itself coincides with school that restarting or turning off the mobile is not a magical solution against this type of malware, but it can stop cybercriminals and make them engineer new ways to maintain access, perhaps being these more visible for device safety systems. But well, apart from security, both on iPhone and, above all, in Android mobiles, make a restart every so often Close processes and release RAM. It happens, as we say, especially in Android, where the system code can ‘fight’ against the manufacturer’s customization layer, making the mobile not do well that we should have been without restarting/off because there will be many waste in the RAM. Bad? That is something that forces us to acquire a new habit. Turning it only takes us for a few seconds, but if we are not used, the easiest thing is for us to forget. The good thing is that many mobiles already include restart and off options programmed in their adjustments.
