Ukraine’s latest tactic is an explosive turn for the war. It’s called “letting in,” and the Russians are falling into the trap.

by

Since the Russian invasion of Ukraine in 2022, the front has been mutating with all kinds of tactics who sought to wear down the enemy. The arrival of drones everything has changedbut the strategies and ingenuity In the use of artillery they have remained a fundamental asset for the advance or defense of the front. For this reason, Ukraine’s latest strategy has disconcerted the Russians. When they reach the bunkers there is no one, and then the surprise comes. Win by letting in. Ukraine is applying a more flexible and lethal defense consisting in “pre-register” their artillery on their own front-line positions, so that when the Russians assault and capture them, they literally enter an already calibrated point to be destroyed: the fort falls, the enemy concentrates, and then comes the massive punishment that turns Russian success into a death trap. After that blow, a Ukrainian assault branch recover the points again devastated, closing a cycle that maximizes ranged damage and reduces the exposure of own infantry, something key in a context of growing shortage of trained soldiers. This logic, denounced even by pro-Russian voices as the strategy of “letting in” is actually a way of imposing the pace: it is not about always preventing them from advancing, but about making each advance expensive, slow and bloody. The “death zone” as doctrine. The tactic works because the battlefield has become in a “kill zone” permanent where the defender attempts to maintain a deadly gap between the leading edge and the rear: artillery is placed further back, out of the usual range of rival drones, and forward positions are fortified to attract attackswaiting for the enemy to enter to destroy them right there with fire and drones. The drone operators They not only strike at the front, they also hunt for supply and reinforcement routes, and any activity near “newly taken” positions becomes visible and attackable. Added to this is the constant mining (including remote) and the use of “ambushers” in the few possible logistical axes, so that the attacker not only pays to capture, but also pays twice as much to try to consolidate. The “let in” tactic after pre-registering a position The decisive blow. The most surprising point about this approach is that the defender does not seek so much to “hold every meter” as to prevent the attacker deploy your second step– When the advancing force attempts to bring in specialized reinforcements (e.g. drone operators to hold the ground), the defender launches fast local offensiveseven if they cost material, to keep the death zone intact and keep the enemy trapped in a space where they cannot settle. Thus, the advance exists on paper or in the drone image, but it becomes tactically sterile: you capture something and, before transforming it into a usable position, it becomes a slaughterhouse, like is described in sectors like Kupiansk. It is a war where “letting in” is not an extra: it is the moment in which the enemy advance stops being progress and becomes a loss. The psychological and moral consequence. These types of dynamics are eroding the offensive will because it forces us to choose between kilometers and livesespecially the “faces” of competent soldiers who know how to move in that death zone: It’s not just that advancement costs, it’s that it costs exactly the most valuable thing. From this arises a dilemma on the front itself: advancing in a big way without preparation means burn trained unitsbut advancing “minimally” or little to be able to report presence saves resources… at the cost of generating absurd situations where you can no longer request fire on positions that officially “they are yours”although in reality they are being crushed or disputed. In this framework, the information war of territorial control is mixed with real survival, and “progress” becomes a very diffuse decision. The technological revolution to the rescue. we have been counting. The bottom line is that Ukraine is at the center of a military transformation: soldiers are the most expensive and difficult resource to replace, while unmanned systems have passed to dominate the combatexpanding on an industrial scale, lowering costs and multiplying impact. The front is increasingly managed from the rear or bunkers with operators controlling the space, and attempts at “classic” breaches become almost suicidal: the key is no longer to launch columns, but to disperse, camouflage and gradually push the death zone back. As the war evolves into swarms, AI coordination and persistent attacks, the advantage is not having the most expensive weapon, but having thousands of cheap weaponsreliable communications networks and the ability to update systems non-stop. The coming war. Thus, the strategic decision moves to logistics and industry: cut off land routes, protect supplies, attack factorieslogistics centers and hidden commands, and do so with reusable media and unmanned is increasingly determining. Victories depend on producing drones en massesecure components, sustain communications Starlink type and dominate the cybernetic layer that can blind, uncoordinate or paralyze an entire front. That is why the strategy to “let in” It does not seem like an isolated trick, but rather a direct consequence of the new battlefield: if the first to enter dies, the one who waits and finishes with precision (with drones, mines, artillery and digital coordination) keeps the initiative even if it seems that is receding.

A video of a Russian soldier ignoring a bomb falling on him is the clue to something deeper in Ukraine

This circulating a clip as brief as it is disturbing: what appears to be a fragmentation munition falls at a soldier’s feet, explodes practically beneath him and, against all logic, the man continues walking as if nothing had happened, “ignoring” the immediate impact of a detonation that, by pure physics, should have destroyed him or at least knocked him down and left him incapacitated. The explanation points to a tactic that is not new. What doesn’t fit. The most striking from the video It is not just that he remains standing, but the absence of the instinctive reaction that any body has to pain and shock, as if the nervous system were disconnected or anesthetized. And here comes the detail that makes the scene even more disturbing: according to Canadian analyst Roythe scene suggests that it is a Russian soldier, and that what we see is not a typical Ukrainian attack, but a deliberate attempt to eliminate him by his own people, perhaps because he was trying to defect. In that reading, the explosion would not be bad luck, but rather a covert execution, with what appears to be una OFSP-0.5, launched with the intention of cutting his retreat short and erasing any uncomfortable history before he crosses a line or surrenders. The “zombies” of Bakhmut. The image does not appear out of nowhere: it fits within a sensation that is repeated from the hardest moments of the siege at Bakhmutwhen Ukrainian fighters they described Russian attacks that seemed written by someone who doesn’t understand human survival. Waves of men advancing without coordination, without visible tactical logic, walking almost in a straight line towards enemy fire, with stories that spoke of soldiers who kept appearingalthough the first had already been killed, and with a strange passivity even under bombardment. We talk about videos where soldiers were seen move slowlystaggering, as if they were stuck in a thick dream, unable to move away even as grenades fell around them. In that framework, the video soldier current seems like the extreme version of the same impression. The drug hypothesis. For months, many Ukrainians have sustained an uncomfortable idea: that part of these attacks are not explained only by incompetence or desperation, but by soldiers “doped” envoyswith substances that reduce fear and disconnect prudence. The accusation appears in direct testimonies: men who seem euphoric or absent, who advance without understanding what they are doing, who do not retreat even if death is obvious, who react late or not at all. Not only that. Suspicion persists because, from a military point of view, the temptation it’s too clear: If what you need is infantry who will walk toward fire, who will endure a corridor battered by artillery, who will not be slowed by anxiety, and who will execute orders in an environment where instinct would say “flight,” a stimulant or narcotic mixture can make a soldier a more manageable asset. Pervitin, an early form of methamphetamine, which was widely used in Nazi Germany The Nazi shadow. To understand why this idea is not science fiction, just look at the most famous historical precedent: Nazi Germany led drug use combat at an industrial level with Pervitina low-dose amphetamine similar to modern methamphetamine that was first popularized in civilian society and then became a military multiplier. wanted something simple: reduce sleep, raise morale, reduce fear, increase aggression and sustain the execution of tasks without rest for days, just what is needed for rapid offensives and to maintain the rhythm when the body should collapse. And it wasn’t just the Nazis, also the allies. Super soldiers. That logic fit like a key in the blitzkrieg lock: continuous movements, mechanized attacks, advance without pause, a sensation of permanent thrust that overwhelmed the enemy not only because of the power, but because of the ability to not stop. He myth of the “super soldier” It wasn’t a futuristic helmet: it was a pill. And if that episode taught anything, it is that armies, when they believe they can gain an advantage or sustain performance, usually put immediate effectiveness before medium-term human cost. Soldiers under the influence. The pattern of effects attributed to this type of stimulant is perfectly compatible with what appears in many stories of the war: less fear, more aggressiveness, less need to sleep, more resistance to fatigue and a certain ease in executing simple commands even in extreme conditions. The price is usually the psychological and physical toll: dependency, depression, impulsivity, loss of judgment, and a progressive degradation of the soldier as a functional person outside of the moment of combat. On the front line, however, that bill is irrelevant to a short-term planner: if what you need is for someone to cross a field of fire today, you care little about what happens to them a month from now. That’s why video on networks It is so symbolic and striking: it seems to be the exact moment in which the body stops behaving like a human that preserves its life and begins to behave like a moving object that only obeys the forward vector. The other side of the coin. However, there is an essential nuance: “zombie” behavior does not always involve drugs. It may simply be the ugliest version from reality: extreme coldlack of equipment, exhaustion, hungeraccumulated sleep, sustained stress and the confusion of a mind that shuts down. The early hypothermiafor example, fits brutally with many clips: slowness, clumsiness, difficulty processing stimuli, confused speech, lost gaze. And in the Russian case there is also a historical tradition of war “fuel” much more mundane: alcohol as a tactical and psychological value, from vodka rations in World War II (used to combat the cold and to give courage before attacks) until modern episodes of indiscipline and documented drunkenness. A sign of the times. In short, the video that has gone viral In networks it leaves that somewhat absurd feeling of “two options”: either it was a Terminator, or the soldier was under some type … Read more

This is how the “impossible” photo of the man falling into the Sun was made

by

It seems like a montage, but it is so real that it has gone around the world just when AI was making surreal images stop impressing us. Andrew McCarthy’s “The Fall of Icarus” has shown that there are still ways to outdo the machine with technical precision and months of planning. Logistical madness. In the photo, a backlit silhouette appears to have launched itself in free fall over the Sun. It is the skydiver Gabriel C. Brown transiting in front of a particularly active solar disk. On the other side of the telescope, the famous astrophotographer Andrew McCarthywhich had begun planning the capture at the beginning of the year. It is, quite possibly, the first photo of this type, since the list of variables to control was insane. They needed the optimal sun angle, a safe height for Brown to launch from, and a perfectly calculated glide path between the sun and the camera. Three-way communication. It was 9 in the morning in the Arizona desert. McCarthy had his telescopes ready and was in constant communication with both Gabriel Brown, the skydiver, and Jim Hamberlin, the pilot of the paramotor from which he would launch. McCarthy followed the aircraft with his telescope and, once it was aligned with the Sun, gave the order. “Okay, I’ll see you,” he said over the radio. “Jump, jump, jump!” Brown jumped at about 1,070 meters above sea level with the engine idling to ensure a perfect angle. “I got it, man!” he heard him say on the radio. The sixth time was the charm. McCarthy told Live Science that the biggest challenge had been finding the paramotor in the sky. Although it was about 2.4 km from its position, the point of the shot was to capture in detail the Sun, which was 50 million times the same distance. It took the team six attempts to correctly align the aircraft with the photographer’s position on the ground. When push came to shove, they could only make one jump, as folding the parachute for a second attempt would have taken too long. Is it really not a setup? It is not, and the secret is in the telescope. As explained PetaPixelcarried a hydrogen-alpha filter to block all sunlight except for a very specific red wavelength that emits incandescent hydrogen. This is how those infernal images of the solar chromosphere are taken: the layer of active “fire” on the surface of the Sun, with its filaments and protuberances especially visible during times of greater solar activity. It is not very different from how other photos of rockets and space stations passing in front of the Sun are taken, but with extra planning and audacity so that the protagonist of the image is, for the first time, a tiny person.

Elon Musk boasted of having created an “apocalypse-proof” car. Now the Tesla Cybertruck’s headlights are falling out

by

Who doesn’t know a C15, prays to any Tesla Cybertruck with this title we headed this article in July 2024. We did it because on social networks it was already common to find comparisons between a Tesla Cybertruck which began selling just half a year before for a price close to $100,000 (sometimes much higher) with the car of “a Spanish farmer flying with three bags of fertilizer and a pregnant sheep in the trunk”, as this X user described. It was no wonder. Since it was first announcedElon Musk did not stop boasting that Tesla’s future electric car was nothing short of indestructible. A story that began crack when, live, the car glass itself could not resist the launch of a steel ball that, in theory, should not have caused any scratches. Now, less than two years after the car went on sale we know that the crack has been getting bigger and bigger. Because Tesla has recalled its Cybertruck for review. This time there have been 6,200 units. It is the tenth time in less than 24 months. Now, the headlights are going out. Indestructible, when it does not self-destruct Elon Musk boasted during the Tesla Cybertruck launch event about having a car “apocalypse proof”. He was talking, we assume, about real apocalypses, not metaphorical ones like the one they are experiencing Tesla sales in Europe. Beyond the jokes, what the owner of the company wanted to show is that he had something like a “armored street car”. In Xataka We already explained why a car that does not deform is a bad idea. If the car does not absorb the impact, it is the passenger who suffers the impact against himself. We are talking, of course, about cars that are on the street, working with all the guarantees. The problem for Tesla is that it keeps call cars for inspection. In the first year he had to do five calls for review. Today it has already been 10 and there are two full months of 2025 ahead, they collect in Electrek. While it is true that some of the problems have been solved with simple software updates, on other occasions they have had to go to the workshop because they were losing pieces in progress. The problem, everything indicates, is the same as on this occasion. The Tesla Cybertruck has some unusual headlights falling out, according to the American media. That is why the NHTSA has had to activate a recall so that 6,197 Tesla cars return to facilities. And Tesla sells headlights that can be installed on the roof of the vehicle as an accessory in its after-sales network, expanding the car’s off-road characteristics. The problem is that those headlights fall out. The glue simply cannot withstand their weight and in some circumstances it ends up expiring. This It hasn’t been the first time that Tesla has problems with the glue used, which has led to calls for review because, among other elements, the decorative molding of the A pillar, the one located on the side of the windshield, fell off. Beyond the possible fun of having an indestructible car that pieces are falling off while movingTesla is experiencing an ordeal with the electric off-roader. The company had the opportunity to make it a flagship, aspirational model and always sell it at a very high price but without aspirations of turning it into a mass product. like Mercedes does with its G-Class. However, it opted for the opposite and now finds itself unable to put the promised versions on the market at affordable prices. But, above all, it does not seem to be selling the expected numbers. And the company says it has a production line ready capable of produce 125,000 units each year. Musk even boasted that they expected sell more than 250,000 units annually. Electrek They point out that less than 65,000 units have been sold since November 2023.

is falling silently since 2022

After escalating during the pandemic to higher levels of its history, the price of rent in the United States started to retreat for the first time in years. The shift is neither punctual nor local: it is now observed on a sustained basis in most large cities and has lasted long enough to be considered a phase change in the market, not a seasonal blip. The question seems clear: why on earth did the rent begin to be transferred precisely now and not before? An unusual twist. After two years of historic increases driven by the pandemic shockrents in the United States have almost three consecutive years correcting National data places the average rent 3-3.5% below from the maximum of August 2022, with interannual decreases chained in the 50 largest markets. That correction is striking for a reason. very simple: It occurs in a country with a chronic housing deficit and with a still stressed cost of living. It is not a collapse, but a normalization after an extreme phase: because even with the decrease, the typical rent is still 20-22% above 2021. Austin as a laboratory. It we count a few months ago. Austin possibly offers the compressed version of what has happened on a national scale: after a boom in demand (internal migration, arrival of companies, cheap credit), the market responded with an expansion of unprecedented offer (an increase of more than 8% in the housing stock in a few years, with permits at rates that surpassed other comparable cities) and a subsequent slowdown due to the rapid rise in interest rates. The combined effect has led to rent drops of 22% from highs and sales price declines of 10-18%. The Austin case demonstrates that when the bottleneck is attacked on the supply side, the price falls before demand is destroyed due to poverty: it cools due to saturation, not due to collapse. National evidence. The pattern is common: in 2024 they were delivered more than 600,000 homes multifamily, the largest flow since 1986. There are still 686,000 under construction (well above the historical average) and 7.1% vacancymaximum of the series. A greater number of competing units forces prices to be lowered or free weeks to be granted to accelerate occupancy. The time that passes from when a home is published on the market until the contract is signed with a tenant now takes longer: 31 days on average compared to 19-20 days at the peak of tightness in 2021. The macro result is the loss of owners’ ability to raise prices in a market where the tenant has regained the margin of choice. Fall mechanics. The 2020-2022 phase combined demand shock (sudden migration + very low rates + change in preferences) with insufficient supply After a decade of under-construction post-2008, the price rose. In 2023-2025 reverse the asymmetry: the pipeline (the set of homes in the process of entering the market, but that have not yet become available) during the boom is delivered just when demand is cools due to high rates and the return of some migratory flows. What happens then? That the excess of units leads to greater vacancy, and vacancy is the nuclear variable that sets the price: after a certain threshold the expected income per empty unit falls more than it is worth keeping the rent high, and the owner adjust the price before than empty time. The fall is not structural but cyclical: if the supply were to stop completely, the pressure would return, as analysts already warn in the same Austin case. Uneven geography. The most intense decreases are concentrated in the Sun Belt markets (Austin, Phoenix, Denver, San Antonio, Orlando, Dallas), where production was faster and vacancy was higher. Markets with expensive land and regulatory barriers (cities such as San Francisco, New York, the NE coast and some Midwest nodes) show even rises because there the supply adjustment arrived late or simply did not arrive. This also confirms the direct relationship between the pace of permits/construction and price moderation: where construction was allowed, the rent fell, and where it was not, it continued to rise. It’s a correction. Most analysts agree on the same explanation. Despite the “rents are falling” narrative, the benchmark matters: the current absolute level is still well above pre-COVID, and the rent-to-income ratio has only returned to “manageable” zone (~23%) in a section of cities, and in areas like Miami or the NE coast it is still overflowing. That is why the experts they underline That anyone who expects to return to 2019 prices does not understand the basis: the new housing built is higher because the cost factors (land, insurance, construction, structural inflation) have not reversed, which suggests that the downward phase has a ceiling. Exportable lesson. The factor that can be copied is not the United States Federal Reserve or migration, but rather the supply elasticity: Austin proves, with an example empirical and measurablethat by authorizing and delivering new housing in large and sustained volumes, the rent stops being a fatalistic variable and begins to behave as an acceptable price due to competition. The rest of the country reproduces the same pattern where supply entered on a scale, and where it did not enter, the price simply did not weaken. Image | Pexels, Eric R.

The Arctic cold was the ideal barrier against invasive species. Now that barrier is falling

by

The Arctic Ocean is one of the hot points as far as climate change is concerned. Separated from the surface by polar ice, this ocean is a place with its own characteristics that go beyond its icy temperature. The barrier falls. A new study headed by researchers at British Antarctic Survey (BAS) He has found evidence of the arrival of an invasive species of Percebe to the waters of the Canadian Antarctic. This has led the team to conclude that the barrier that previously represented the low temperatures of the polar ocean is falling. Amphibalanus Impherevisus. The species in question is a type of Balánido sometimes known as bay’s percebe (Amphibalanus Impherevisus). These crustaceans are disturbed in a distant way with the common perclabes (Cornucopia policipes), but its presence is considered a problem and not A food source. The species has already become a regular of the waters of Europe and the Pacific Ocean, where it causes problems when attached to ships, pipes and infrastructure of different types. However, until now it had remained absent in the waters of the Canadian Arctic. EADN. The detection of the invasive species was carried out thanks to the study of the bars coding of the Environmental DNA (Edna). Living beings are leaving our genetic imprint in our environment: detached cells, waste and other biological remains. This technique allows to detect the presence of a species (or several) without finding a single specimen, only through environmental samples, in this case, water. The details of the study were Published in an article In the magazine Global Change Biology. Climate change, the great suspect. The Arctic is one of the regions most affected by climate change. There are two factors, both related to the increase in temperatures in this region, which have contributed to the expansion of this percebe. The first factor is the increase in maritime traffic of the Arctic associated with the thaw and the opening of new routes. Generally, the team explains, these invasive species usually arrive in the ships of the ships or in their ballast tanks. The second factor is that the waters of the Canadian Arctic no longer present such hostile conditions for the proliferation of foreign species. “Climate change is really in the nucleus of this problem. The ships are increasing in number because the reduction of sea ice has opened new nautical routes. It adds to this that the invasive species that the ships bring to the Arctic also are more likely to survive and establish populations due to the warmest temperatures of the water,” explained in a press release Elizabeth Boyse, who led the study. An issue to clarify. According to the team responsible for the study, there are still details to corroborate with respect to the spread of this species in the Canadian Arctic, starting to know if the DNA detected responded to larvae in transit or a more stable and fruitful population. To know this type of detail, it will be necessary to complement the study with other techniques, such as direct observation of animals.

The hours worked are falling so much in the Netherlands that, unintentionally, they are adopting the four -day week

by

When talking about countries with high productivity, all eyes tend to Go to Germany or Ireland. However, the Netherlands has become a European reference when it comes to significantly reducing the volume of working hours in its days, naturally approaching the four -day week model. This trend attracts attention both for its impact on everyday life and for the country’s economic data, banishing alarmist theories About economic ruin. According to An analysis of the Financial Timesthe Dutch enjoy a high quality of life, partly thanks to their system of Flexible and well -paid employmentwhich has evolved to prioritize personal well -being over the traditional model Based on long days. Netherlands and its reduced day. According The published by the 4 Days Week FoundationThe Netherlands have structured its labor market so that the full day is not the most widespread model and a large part of the employees prefer to work less hours voluntarily. However, far from being conceived as a precariousness model, it has become an example of balance Between work and professional life. According to data Eurostat of 2023, the middle day in the Netherlands is the lowest in Europe with only 32.2 hours worked, compared to 36.4 hours in Spain or 35.5 hours in Ireland. According to the data published by the Financial Timesaround 50% of the Dutch work part -time, and the proportion is even greater among women, which reach up to 75%. Not only does you work less in part -time days. Beyond the obvious cut involved in working under a model of part -timefull -time days are also from the short ones in Europe with 39.1 hours, only surpassed by Denmark with 38.7 hours per week. In Spain, the Real full day It stands at 40.2 hours. Being shorter, the Dutch tend to compress it in four days instead of five. Bert Colejn, an Ing Bank economist, assured the Financial Times That “the four -day work week has become very, very common. I work five days, sometimes they criticize me for working five days!” Greater productivity and better salaries. The Eurostat data They emphasize that Holland is among countries with Greater productivity per hour worked, standing at 45.3 euros per hour, compared to 29.4 euros in Spain, but far from the productivity of the Scandinavian countries that or Ireland that exceed 60 euros per hour worked. This conjunction of high productivity and reduced days has caused a situation of salary precariousness to be generated, but, on the contrary, Holland has maintained wages above the European average. According to Eurostatthe average of the gross salaries of Holland, adjusted by purchasing power (PPA), is 16.2 euros per hour, while in Spain it is 11.8 euros per hour. The European average is 14.9 euros per hour. Netherlands does not have four -day work week. In strict terms, the Netherlands have not applied any day reduction policy (such as Yes, Spain tries to do it) or four -day workday. However, almost without proposing it, the Dutch labor market has adjusted so that, at the practical level, its companies have implemented the working day of four days without wage reduction after decades of conciliation policies.

The teleworking is falling in all of Spain. In all? No, an village resists the invader: the officials

by

Far from the rise that He lived during 2020the teleworking has entered into A downward trend In the private sector. The face -to -face consolidates as the model preferred by companieswith offices that recover prominence. Given that reduction, a model has gained prominence: the Hybrid Day. However, there is an area in which teleworking seems to resist this setback: Public administration. Companies return to the office. Companies seem to have spent page with teleworking, and bet on the return to the face -to -face. According to the report ‘Digital Society in Spain 2024‘ Published by the National Observatory of Technology and Society (ONTSI), 69.9% of employed people always work away from home, compared to 30.1% that telework to some extent. Of that percentage of teleworking, only 9% of the total does so permanently from home (something that also confirms INE data), while 21.1% apply it under a model of Hybrid Day with between two and four face -to -face work day. The public sector walks in the opposite direction. Despite the tendency towards the face -to -face of the private sector, the General State Administration maintains much higher figures of employees that telework, and this trend does not seem to have come to an end. According to 2024 data publishedby The economist49.15% of the officials and employees of the State Administration are welcomed to teleworking. This percentage is equivalent to about 87,618 public workers who carry out their work remotely, mainly, with a maximum of three weekly days. This difference in approach to the teleworking of the State Administration adds points, Next to the salary or labor stability, so that public employment has become the Preferred Labor Alternative For many employees, in the face of the temporality, precariousness and face -to -face of the private sector. More public teleworking. The Digital transformation The administration has allowed progress in the implementation of teleworking, especially in those positions that do not require direct contact with the citizen. A recent example is starred by the Basque Government, which has reached an agreement with the unions to increase teleworking two days a week to both officials and labor personnel, such and As you collect The Basque newspaper. However, the most relevant thing about these teleworking measures that are being adopted in the administration is that the criterion ceases to focus on the nature of the job, to focus on the tasks that can be done remote. This task approach opens a new way when organizing public employment, traditionally face -to -face and bureaucratized. Unique criteria. The great “but” of this commitment to maintain and even expand teleworking in public administrations is the lack of a unique criterion for the different administrations. The General State Administration has its own norms included in article 47 bis of the Basic Statute Law of the Public Employee. However, each autonomous community and municipalities have power to regulate the work model of its officials, so there is no unique rule that regulates it, although tasks can be similar. For example, the Junta de Andalucía has just regulated the remote day of its officials, limiting it to 40% of its day. That is, two days, in front of The three days which are allowed in the General State Administration. Teleworking in state administration. As It is established In the basic statute of the public employee, the State Administration allows to telework up to three days per week, “provided that the nature of the position allows and the adequate provision of the service is guaranteed.” This formula has been mainly implanted in those bodies that They perform technical tasksof analysis or information management. General Bodies of State Administration. Formed by administrative or administrative assistants who carry out tasks related to the management of documents or databases. Digital and Informatics Administration. Those officials in charge of software development, management of networks or computer systems of the administration. Department of Justice. Officials who work in the procedural and administrative management and processing of the judicial documentation, provided that their position does not require face -to -face attention. Finance staff. Administrative or tax analysis technicians, in charge of preparing files, economic-financial analysis and tax management and finance inspectors, when they must perform a more technical task. Statistics officials. Those officials assigned to the General Corps of State Statistics or Statistics Technicians who carry out data, reports and studies. Department of Culture. Higher auxiliary or technical technicians of libraries and archives dedicated to documentary digitalization or content management.

Falling from 10,000 meters without parachute was a safe death. Until Vulović appeared

by

Suddenly, the hostess Vesna Vulović Recover knowledge. He is bite and can barely move due to his partner’s inert body. Half of Vesna remains on the plane, and the other half is out. What had just happened was going to challenge physics for decades: no one, neither before or after, had been able to survive a free fall without parachute from 10,000 meters high after the explosion of a commercial flight. The question since then is simple: how the hell managed to leave alive? The wrong flight. On January 26, 1972, Vesna Vulović, a young 22 -year -old Yugoslava flight Jat company for a confusion of names with another partner. The itinerary included several scales between Stockholm and Belgrade, and nothing presaged that it would be the most extraordinary and tragic flight of his life. The accident. After taking off from Copenhagen to Zagreb with 28 people on board, the plane reached cruise altitude. Minutes later, at 4:01 p.m., while the then Eastern Germany, He disappeared from the radar suddenly. An explosion at the front of the luggage compartment left the McDonnell Douglas DC-9 in two to more than 10,000 meters high. What followed was a brutal vertical fall, a bleak scenario in the snowy mountain of Srbská Kamenicein the then Czechoslovakia. There was only one survivor: Vesna. Silence: an attack. Just a few hours after the accident, Czechoslovacos secret services They took control absolute of the place. Access to press was not allowed, much less civilians. The next day, an unidentified man, in a somewhat strange Swede, called the Kvällsposten newspaper ensuring that he was Croatian and a member of a nationalist group that had placed the bomb. The Yugoslav government immediately pointed to The UstachaCroatian ultra -right organization. Ten days later, the remains of a alarm clock supposedly linked to an explosive were presented as proof. Black boxes were never found, there were never arrests, or claims by any organization. An McDonnell Douglas DC-9 by Jat Airways identical to the accident The documented miracle. As we said, the official report indicated the cause of the accident Like a bomb placed by a Croatian nationalist group, although the culprits were never identified. Even so, the authorities closed the case in 1974 attributing it to an explosive attack. The official story argued that Vesna fell from More than 10,000 metersprotected by a series of improbable factors: a catering cart that kept it trapped in the fuselage, the friction of the air that damping the fall and the so -called terminal speed (maximum speed that reaches a body moving within an infinite fluid under the action of a constant force), the snow on the slope of the mountain that reduced the force of the impact, and finally a part of the relatively intact plane protected from the final blow. That was so amazing that even the mythical Mythbusters reached Recreate the case And they concluded that the possibility of surviving was not void, although, of course, tiny. Tributes. Vulović suffered multiple fractures, entered a coma for almost a month and was temporarily paralyzed from the waist down. However, he managed to recover, walk again and even fly again. In fact, the woman was honored in London By the book Guinness With a record that remains: that of the person who has fallen without parachute and has survived (prize, by the way, delivered by Paul McCartney himself). The doctor. Over the years, Vesna shared Some memories rebuilt from what they told him. In her words and those of the man who rescued her, a former German army doctor named Bruno Henke, she was in the central part of the plane, not in the tail, contradicting the official theories that explained their survival. Henke, a neighbor of the area, argued that he found it in the middle part of the plane, at the height of the wings. He found her head down, with the torso out of fuselage and legs inside. Vesna always He believed his testimonyIn fact, he had a close relationship with Henke. Vulović (right) during his visit to Czechoslovakia, November 1972 Something does not fit. Let’s recapitulate: Vesna’s body, as we said at the beginning, was partially inside and outside the fuselage, with that “miraculous” cart literally nailed to his back. And here appears one of the great doubts, because that incongruity undermines the physical hypotheses about how he could survive, since a person in the middle zone of the device could hardly have remained within it After an explosion that left it at two high. Herself He pointed out thatas the plane was half empty, it probably moved among the passengers, according to the service protocol. To do everything a little more complicated, Vesna’s amnesia about everything happened on that date prevented verifying the details. Boom. In 2009, the story He took a turn unexpected. An investigation by journalists Peter Hornung-Andersen, Pavel Theiner and Tim Van Beveren, published by Tagesschau and issued by the ARD chain, He unearthed documents Dak For mig fighters of the Czechoslovak Air Force when it flew to low height, just 800 meters from the ground. According to This versionthe plane descended by an emergency and was confused with an aerial threat when entering a restricted area, perhaps linked to a Soviet missile base, or coinciding in the airspace with the plane of the Soviet leader Breznev’s own leader in official visit to East Germany. The demolition would have been Undercover by the Police Secret, which built the history of the “world record” to hide the incident. This version was based on official documents, testimonies of witnesses who saw the plane flying whole before exploding, and what is doubtful, the apparent physical impossibility of surviving a fall from such a height. The official silence. Czech authorities They denied categorically the alternative version without offering contrary evidence. They never explained the absence of black boxes or responded with documentation to refute the new findings. A general came to declare that “at least 200 people should … Read more

The problems of nuclear fusion are falling behind each other. Optimism cornering denialism

by

The challenges raised by the nuclear fusion intimidate. And it is to replicate on our planet and small scale the same reactions that take place in The interior of the stars It is a titanic challenge. Even so, The human being has already traveled A very important part of this path. There is a belief that defends that in the field of nuclear fusion we have barely advanced since World War II, but, as we will see in this article, it is not so. There is much to do, but we have advanced a lot. In order for electric power plants equipped with fusion reactors to be viable, it is necessary to solve problems that are still dealing with engineers. And it is that the challenges posed by nuclear fusion right now reside in the field of engineering, and not in that of basic science. In fact, Spain will actively participate In the search for the solution to one of these problems thanks to IFMIF-DONES (International Fusion materials irradicion facility demo-eraned neutron source), The installation that is under construction (Granada). Its purpose in broad strokes will be to develop a source capable of producing high energy neutrons with the intensity and volume of irradiation necessary to test candidate materials to be used in future fusion energy plants. This is one of the pending challenges, but many others have already been left behind thanks to the great work that scientists have carried out in experimental reactors, such as the already “retiree” JET (Joint European Torus), which is housed in Oxford (England). Let’s trust the reactor JT-60SA of Naka (Japan), and, above all, ITER (International Thermonuclear Experctor reactor), are up to expectations. Eurofusion and the University of Texas have made two new relevant contributions We can imagine in an intuitive way a nuclear fusion reactor as a pressure cooker in which two essential ingredients are cooked: deuterium and trity. To ensure that the nuclei of these two hydrogen isotopes merge and release the neutron that will ultimately allow us to obtain a large amount of energy it is necessary to confine them in an extremely hot plasma. In fact, so that this process takes place, a temperature of at least 150 million degrees Celsius must reach. Scientists know how to do it, so submitting the deuterium and tritium nuclei at the pressure and temperature to get me to merge is no longer a problem. What still represents a challenge is to achieve Keep turbulence under control. Otherwise, the plasma will be destabilized, its density in the critical regions will be affected and the support of the fusion reaction over time will not be possible. The mechanisms that govern this process are very complex, but little by little physicists and engineers who work in fusion energy are getting them better. The QCE (‘Quasi-Continuous exhaust’) regime is characterized by eliminating periodic instabilities that occur on the edge of plasma In broad strokes what they intend is to minimize turbulence so that the loss of plasma energy is minimal. Two of the tools that these technicians have are the artificial intelligence (AI), which is playing a very important role in understanding the mechanisms that govern plasma behavior, and Rebco superconductor magnets. In fact, The sparc fusion reactor that is building the American company Commonwealth Fusion Systems (CFS) uses them. Precisely Eurofusionthe European organization that is responsible for promoting and supporting the scientific research necessary to bring to fruition The European Nuclear Fusion Planhas recently made an important contribution in this field. And it has shown that in the reactors Tokamaklike Jet or Iter, it is possible to use an operation mode known as Qce (Quasi-counts exhaust) that is characterized by eliminating periodic instabilities that occur at the edge of plasma, and, at the same time, it supports high density in this region of gas and preserves a very high level of energy. Gradually the confinement and stabilization of plasma are no longer a problem. The other recent contribution in which I propose that we investigate it briefly has been carried out by a team of researchers from the University of Texas and the National Laboratory of Los Alamos, both in the US. In the article they have published in Physical Review Letters These scientists propose the creation of a magnetic confinement system without leaks ten times faster, according to their calculations, than the standard method without sacrificing a precision apex. This innovation is important because it helps to resolve the containment of high energy particles within the reactor, and, therefore, to avoid the loss of temperature and density in the critical regions of plasma. Yes, as I mentioned a few lines above, much remains to be done in the field of nuclear fusion, but definitely every day we are one step closer to commercial fusion energy.
