A scientist wants to build a space shield against solar storms. Your secret weapon: lithium and barium

by

Predict the arrival of very strong solar storms It is important for many reasons. Not only to keep an eye out and not get lost the most beautiful auroras. Also because these could affect satellites or terrestrial communications systems, so it is important to take precautions. The problem is that, no matter how much prevention methods have improved, we cannot do much more than be prepared for what is coming. Today there are no ways to stop these solar storms. However, a scientist from Boston University has announced that it is working on a method to strengthen the Earth’s natural shield against this type of phenomena. A stronger shield. The scientist in question is called Brian Walsh and is working in what he himself has called a wall against solar storms. Its objective is to send six ships to strategic points in a geostationary orbit, so that they release chemical elements capable of strengthening the magnetic field. These should be elements such as lithium or barium, since they are easily converted into positively charged ions when solar ultraviolet radiation hits them. At that point, the cargo released by the ships is converted to plasma. Precisely, what reaches Earth with solar storms is also plasma. However, there is a big difference. The one that comes from the sun consists of charged particles that move at very high speed, with great energy. On the other hand, what would be released into the magnetosphere would be cold, static plasma, which acts as a kind of wall, preventing this high-speed plasma from passing through the magnetosphere. A good shield when the activity is not too intense. The Earth has a great shield against solar storms. Generally, our magnetic field prevents these charged particles from the Sun from crossing into our atmosphere. This is because the magnetic field generally acts as a kind of rail on which the plasma circulates. The electrically charged particles are retained on these rails, but do not cross to the other side. They can only reach the atmosphere at the poles, where the inclination of the magnetic field lines acts as a kind of funnel. Even so, the charged particles that come from the surface of the Sun may already arrive somewhat weakened there. They interact with the gases in the atmosphere, exciting the atoms and causing the release of the light that makes up the auroras. But there are usually not very detrimental effects on communications. On the other hand, if the solar storm is very intense, the particles may be able to deform the rails of the magnetic field, filtering at the poles, but also in other places in the magnetosphere. Historical consequences. The consequences of these types of events have been seen numerous times throughout history. The most dramatic case was possibly that of Carrington eventwhich took place in 1859. It is considered the most powerful solar storm that has been recorded in history with consequences on Earth. Because of this large release of plasma from the Sun, auroras were seen in places as far from the poles as Hawaii and Cuba, but there were also less noticeable consequences, such as the burning of telegraph lines in many parts of the world. Another very notorious and dangerous case took place during the Vietnam War, in 1972, when a solar storm caused the accidental detonation of several magnetic underwater mines. And much more recent is the Gannon Storm, which in 2024 affected the GPS systems of planting tractors in several locations in the United Statescausing losses of 500 million dollars among farmers. But the situation could be worse. It is estimated that a major storm like Carrington’s could occur once a century. There hasn’t been one this big since then, so it could happen in the not too distant future. And today we depend much more on technologies than then. It is estimated that the losses could be more than 2 billion dollars. A natural process. This artificial wall that Walsh wants to create is inspired by a process that occurs naturally. And the thing is that, from time to time, small fragments of the Earth’s atmosphere break off and join the magnetic field, reinforcing it before the arrival of charged particles from the Sun. Lithium and barium would do something similar, artificially. Simulations only: For now, Brian Walsh has only made simulations of his invention, he has not tested it in space by any means. He himself recognizes that it is a complex process, so it must be done perfectly so that it causes more benefits than problems. Releasing ionizable elements at random could be harmful if not done in the right place. In addition, ways must be found to put ships in the correct place in their orbit before the storm arrives, so it is important to speed up the process while improving prediction methods. Handicaps. Although it may seem like a lot of mass is required to carry out this procedure, Walsh insists that the payload needs fall within current launch capabilities. However, he recognizes that it is an expensive process. Therefore, it would be necessary to look for ways to optimize it so that the necessary investment is not so large. For example, you want to work on pulsed release so that ionizable material is not wasted. In short, this method of controlling space weather is not at all something that will be used imminently, but it is clear that in the future we will need something like this. If not this method, another, but we greatly need something that protects us from the harshest elements of the Sun. Image | NASA | Walsh et al.

Walking 20 minutes a day after age 55 is very good. The secret of healthy maturity is to do it much earlier

by

An increasingly repeated idea is that, to have a quality retirementyou have to keep moving throughout maturity and with adequate physical activity. The problem is that many times people wait until they are 55 years old to start taking care of themselves and in many cases because they already have a metabolic disease. And this should make us aware that the sooner we start taking care of ourselves, the better. Walk It has been crowned as the star exercise for older adults, and the scientific evidence that supports it is overwhelming. A study from the year 2023 points out that walking 30 minutes a day for 5 days a week reduces the risk of age-related diseases, although it is especially emphasized that it must be done at a high speed and that requires some effort for the body and not as a simple walk. If this is done, we will be significantly reducing the risk of suffering from cardiovascular diseases and type 2 diabetes, but also protects against dementia. And if that were not enough, a review conducted this year with 180,000 participants demonstrated an 18% to 30% reduction in mortality from all causes with moderate levels of physical activity. In figures. It’s not that Olympic records need to be broken, but simply taking 5,694 steps a day is associated with a 13% lower risk of mortality from all causes. And as we have said before, if it is done a speed high, a greater benefit is achieved. When to start. If the benefits in middle age are so incredible, why does science demand that we start much earlier? The answer lies in sarcopenia, which is the process of loss of muscle mass that we face when we begin to age without doing any type of strength exercise. And that is why the deadline of 30 years is set to begin to remedy it. Because? From this age onwards, it has been seen that between 3% and 5% of muscle mass is lost per decade. according to the NIHand other studies suggest that this figure can be between 3% and 8% per decade after age 30. AND from 60 years old the rate of decline becomes even greater. With all this information, it is estimated that right now between 10% and 20% of older adults suffer from sarcopenia, and lack of exercise is the main factor that worsens this progressive muscle loss. The recipe. The WHO here is very clear in its guidelines and, curiously, it does not make reductions upon reaching retirement, so it does not understand a specific age from which you must exercise no matter what, but rather it points out that you should always do it. That is why their recommendations are exactly the same for adults from 18 to 64 years old as for those over 65 years old: relativize. Between 150 and 300 minutes a week of moderate aerobic activity (such as walking), or between 75 and 150 minutes of vigorous intensity. Furthermore, the WHO asks to incorporate muscle group strengthening exercises at least two days a week for all adults. In the specific case of adults over 65 years of age, the only difference is that activities that improve balance must be added to the general recommendations three or more days per week to avoid fatal falls.

They promised us Rapunzel’s hair with very expensive cosmetics. Science says the real secret has been in your kitchen for millennia

by

Mythical representations of women, whether Botticelli’s Venus, the Hindu goddess Lakshmi or the maidens of Arthurian legends, often share an unmistakable trait: long, flowing and seemingly unattainable hair. It’s easy to think that such lengths are confined to the realm of mythology, untouched by the harsh reality of split ends and frizz. However, just swipe through TikTok or Instagram to find content creators sporting hair that would rival Rapunzel herself. Many of these influencers They promise that your hair has grown at a dizzying rate thanks to a specific technique: hair oiling or hair oiling. But, faced with shelves full of exotic formulas and luxury serums, an inevitable question arises: do we really need expensive products or has the ancient secret always been hidden in our kitchen in the form of olive oil? The resurgence of an ancient ritual. Although the term hair oiling It may sound like a modern invention packaged for Generation Z, the reality is very different. This practice was not born yesterday under the ring of light of a smartphone. Hair oiling is a technique deeply rooted in ayurvedic medicine from India, with Sanskrit texts from more than 5,000 years ago that already recommended infusing hair with natural oils to restore its shine and relax the mind. Likewise, in ancient Egypt also ointments were used based on animal fat or castor oil for similar purposes. What has changed then? The showcase. He hair oiling In a few months it has gone from being a “legacy trick” to an essential aesthetic ritual. Social media has choreographed it into a highly recognizable scene that includes a slow massage, meticulous application of oils before washing, a warm towel, and blow-drying to an incredibly shiny finish (glossy). Among the avalanche of coconut, argan and jojoba oils, olive oil has begun to reclaim its throne, not only because of its accessibility, but because it has historically been the cornerstone of Mediterranean cosmetics and the basis for extracting the properties of countless medicinal plants. The science behind the shine. Beyond visual aesthetics, the big question is whether slathering your hair in oil really works. The answer from science is a resounding yes, although with important nuances. Rocío Lajarín, doctor in Pharmacy and CEO of Alma Secret, explains in GQ that hair is made up of 90% proteins, mainly keratin. “When we use oils with structural affinity, we manage to reduce protein loss and reinforce the resistance of the hair shaft,” he says. The portal Healthline adds that regular oiling reduces “hygral fatigue” (the repetitive swelling and drying of the hair fiber when wet), acting as a cement that protects the cuticles. If we focus on “liquid gold”, clinical studies support its many benefits: Deep hydration and elasticity: An investigation of the Journal of Cosmetic Science demonstrates how olive oil It penetrates the hair fiber thanks to its high content of essential fatty acids, significantly improving hydration and resistance to breakage. A cocktail of vitamins: Virgin olive oil rejuvenates hair because it contains vitamin E, vitamin C (which stimulates collagen formation) and vitamin A (enhancers cell regeneration). Shield against damage and the sun: The International Journal of Trichology emphasizes that extra virgin olive oil contains hydroxytyrosol, a polyphenol that fights free radicals and cellular damage induced by UV-A rays. In addition, it is highly effective in reducing damage after subjecting hair to chemical processes such as dyes. Antifungal action: The same International Journal of Trichology points out that olive oil has an inhibitory influence on fungi that attack hair, such as Microsporum gypseum. The great debate: Does it make hair grow? This is where dermatology collides with internet myths. Dermatologist Andrea Combalia warns in Telva that at hair oiling “Many benefits are being attributed to it that are not real, such as hair growing faster or increasing its density.” Doctors consulted in Cleveland Clinic They agree that growth rate and thickness are predetermined by genetics, age and hormones. Oils prevent breakage (allowing length to be retained), but do not accelerate the growth phase from the follicle. However, dermatologist Ana Molina contributes in Trends a fascinating fact. It has been observed that the phytoestrogens present in olive oil can have an antiandrogenic effect by inhibiting the enzyme 5-alpha-reductase (which converts testosterone into DHT). Since DHT causes miniaturization of follicles in androgenetic alopecia, “phytoestrogens may help prevent or slow its progression.” Roots or just tips? This is the point of greatest controversy. Oiling the scalp before washing protects the lipid barrier of the skin against the aggressive surfactants in the shampoo. However, hairdresser Daniel Gil in Marie Claire and Dr. Steven Walker in GQ They are blunt: if you have an oily scalp or suffer from seborrheic dermatitis, you should avoid applying oils directly to the roots. Dr. Shilpi Khetarpal of the Cleveland Clinic confirms this: if you are prone to dandruff, applying oil can worsen the problem by feeding the fungus Malasseziacausing more inflammation. In these cases, the hair oiling It should be strictly from medium to ends. A ritual with common sense. At the end of the day, olive oil is not going to rewrite your hair genetics or magically transform you into a Renaissance painting. What science tells us is much more pragmatic and, at the same time, liberating. The true value of this trend lies in understanding hair care as a ritual that respects our natural hair structure, and not as a compulsive accumulation of synthetic cosmetics. Olive oil is a powerful, accessible and dermatologically endorsed tool to defend our hair from pollution, the heat of straighteners and daily wear and tear. Applied with common sense, the liquid gold of our Mediterranean diet is also confirmed as the best cosmetic in our bathroom.

secret training for war in Ukraine

by

The scene took place a few months ago. Ukrainian soldiers surprised British instructors when they discovered that many NATO armies still They did not use anti-drone networks on a regular basis. After several years of war, Ukraine was beginning to teach the West how to survive on a front dominated by drones. Much more than drones. For much of the Ukraine war, the relationship between China and Russia has been interpreted primarily in terms economic and technological. Beijing bought Russian oil and gas while Chinese companies appeared linked to the supply of electronic components, drones and machinery useful for the Russian military industry. However, the revelations he has had access Reuters on the secret training of Russian military in Chinese facilities point to something much deeper: China would not be limiting itself to indirectly supporting the Russian war economy, but rather participating in the tactical and doctrinal training of soldiers who then return directly to the Ukrainian front. This enormously changes the dimension of the relationship between both countries. War as a military classroom. According to the documents and sources European intelligence agencies, some 200 Russian soldiers were trained discreetly in China at the end of 2025 under an agreement signed between senior commanders of both countries. He program included training in FPV drones, electronic warfare, army aviation, mechanized infantry and demining. Some sessions took place in military centers in Beijing, Nanjing, Zhengzhou or Shijiazhuang. What is important is not only the relatively small number of soldiers, but the profile of many of them: instructors and commanders capable of relaying that knowledge to whole units once back in Ukraine. In other words, China would not simply be sending technology, but helping to perfect the way Russia fights modern war. China learns while Russia fights. It just so happens that the relationship also greatly benefits Beijing. The People’s Liberation Army has not fought a major war in decades and the Russian invasion of Ukraine has become the largest military laboratory real of the planet. Russia brings direct combat experience in drones, trenches, electronic warfare and mass attrition. China provides industrial capacity, advanced simulators, technological production and training methods increasingly sophisticated. The exchange is extremely valuable for both. Moscow gains access to technology and training difficult to obtain under Western sanctions, while Beijing can observe how modern weapons, tactics and doctrines really work without being officially involved in the conflict. Silent revolution. The heart of all this cooperation revolves around drones. Ukraine has completely transformed the way it fights using cheap FPV capable of destroying armored vehicles, fortified positions and even helicopters. Russia had to quickly adapt to that reality and now appears to be turning to China to further professionalize part of that ecosystem. The documents describe simulator training flight, coordinated use of drones with mortars, electronic warfare against enemy drones and physical interception systems through networks. All of this reflects the extent to which modern warfare is ceasing to depend exclusively on large traditional platforms to increasingly focus on cheap, massive and very difficult to neutralize systems. Europe’s concern. For the European agencies, what is truly disturbing is that part of those soldiers trained in China already they would have participated later in combat operations in occupied Crimea and Zaporizhzhia. This means that the knowledge acquired in Chinese facilities ends up being applied directly on the European battlefield. Beijing, for its part, continues to publicly defend a neutral position and continues to present itself as a possible peace mediator, but this type of cooperation seriously erodes that image. In the eyes of many Western governments, China would be entering a much more sensitive gray area: not officially sending its own troops or weapons, but contributing to improving Russian operational capacity in an active war against Ukraine. Increasingly military alliance. The revelation It also confirms the extent to which the “limitless” partnership announced by Xi Jinping and Vladimir Putin before the 2022 invasion has evolved far beyond simple joint exercises or diplomatic statements. China and Russia no longer seem to limit themselves to coordinating political positions vis-à-vis the West, they are beginning to share knowledge combat practices, training and doctrine. The most significant detail may be precisely the secrecy of the agreements: prohibition of media coverage, restrictions on information to third parties and programs developed discreetly away from the international spotlight. All this suggests that both countries perfectly understand the political sensitivity of a cooperation that, although still indirect, gets closer and closer to China to the real workings of the war in Ukraine.

Almost 2,000 years ago a man died with a mysterious case while fleeing Pompeii. We finally know his secret

by

Get in the situation. It’s any day of any month and you are at home doing something when suddenly you hear screams in the street. You look out the window and see people running away in terror. Not only that. In the distance you see how the ash and burning rock rise from a volcano that both you and the rest of your neighbors thought were immersed in unalterable lethargy. What would you do in the face of such a scenario? something similar They lived 1947 years ago the Pompeians. Now we finally know what one of the unfortunate people who did not manage to save himself did: hold on to your briefcase of doctor. When Vesuvius woke up. The ruins of Pompeii were discovered long ago several centuries and archaeologists have been unraveling its mysteries for decades, trying to know above all what happened that fateful August 24, 79 AD (some versions speak of October) in which Vesuvius erupted and condemned the city of Campania, along with other towns such as Herculaneum, Stabia and Oplontis, asphyxiated under a layer of ash. However, despite all the research and rivers of ink that have flowed on the subject in recent years, the ruins of Pompey continue to retain their ability to surprise us. A figure in Ortho dei Fuggiaschi. One of the corners that has aroused the most fascination is the Ortho dei Fuggiaschithe ‘Garden of the Fugitives’, where we have found the remains of some 13 victims of Vesuvius. The reason is very simple: thanks to the method archaeologist molding Giuseppe Fiorelli20 centuries later, their corpses continue to starkly reflect the desperation of those men, women and children who tried to save themselves while their city was eclipsed by a dense rain of ash and lapilli, the walls collapsed and Vesuvius spewed pyroclasts. We knew that the victims who ended up perishing in the Ortho dei Fuggiaschi were probably seeking refuge, we also have a fairly precise idea of What were your last moments like? before dying. Thanks to Fiorelli’s plaster mold method we can even visualize the scene. The big question is… Can we go further? Who were those people? What did they do? What did they do before leaving their homes on the run? They are fascinating questions. Especially because, before perishing, some victims of Vesuvius they left us clues about your routine. There are cases, for example, in which the scene suggests that the victims were carrying jewelry and coinswhich leads us to think that they were trying to keep their most valuable possessions safe, perhaps so as not to lose them. Perhaps to start a new life in an impulse not so different from the one we would have today. Clinging to the medicine cabinet. Now researchers have discovered another story in it Ortho dei Fuggiaschil. More than 70 years after the first excavations and thanks to the use of To be more precise, scientists have identified a small box of organic material with metal parts and a series of instruments “compatible with a medical kit.” For example, a slab of slate that could have been used to make medical or cosmetic substances and surgical instruments. The x-ray and tomography examination has also shown a cloth bag with bronze and silver coins and a mechanism with a toothed wheel that allowed the box to be closed. Those responsible for the site stand out Furthermore, the study was carried out without putting the molds at risk. The decline of a doctor? That is the hypothesis with which the researchers work, who believe that the briefcase gives us a clue as to who the person who died next to him was. “He was probably a doctor, a victim of the tragedy while trying to escape, taking with him some of the tools of his trade,” he explains in a statement the Archaeological Park of Pompeii, which insists that the instruments located inside the case provide us with “a valuable and rare clue about his profession.” “2,000 years ago there were people who were not limited to practicing medicine during office hours, but were doctors at all times, even when fleeing the eruption, which was thwarted by the pyroclastic cloud that reached the group of fugitives who were trying to leave the city through Porta Nocera,” reflect Gabriel Zuchtriegel. “This man took his instruments with him to be prepared to rebuild his life elsewhere thanks to his profession, but perhaps also to help others.” Images | Pompeii Archaeological Park In Xataka | 2,000 years later, Pompeii continues to reveal fascinating things: the latest is a blue room for unknown uses

Benidorm triples its population in summer and does not run out of water. The secret is a miracle of invisible engineering

by

We assume that when we turn on the faucet water comes out. It is an almost automatic, everyday gesture that we rarely stop to think about. However, ensuring that this resource springs up clean and safe in Benidorm, a city that its population triples In the middle of the summer high season, it requires a true miracle of engineering and management. In the Marina Baixa, one of the regions of the Valencian Community with greater water stresscatering to millions of annual visitors is a colossal puzzle. As reported by local mediathe philosophy of those who operate this gear is perfectly summarized by Ciriaco Clemente, manager of Veolia in Benidorm: “In a territory where the pressure on water resources is structural and permanent, guaranteeing that the water reaches the tap in perfect sanitary conditions and that, once used, it returns to the environment without damaging it is not an option, it is an obligation.” The challenge of quantity and quality. The water challenge is not exclusive to the Alicante coast, it is a national problem. According to official data from the Ministry of Health (SINAC)the quality of water in Spain is increasingly threatened. The filtration of nitrates from industrial agricultural activity is saturating the self-cleaning capacity of many aquifers, putting local water treatment plants in hundreds of municipalities in check, especially in inland Spain. While much of inland Spain deals with nitrate pollution, Benidorm faces its own perfect storm: extreme seasonal demand and the threat of shortages. The city not only needs to ensure that there is enough water for everyone, but that its quality is impeccable under all circumstances, regardless of whether it comes from the Guadalest reservoir, the Amadorio reservoir or the Bajo del Algar Canal. To overcome this crisis, the tourist capital has shielded itself around two essential infrastructures managed by Veolia: the Drinking Water Treatment Station (ETAP) and the Wastewater Treatment Plant (WWTP). Beyond thirst. Water quality is synonymous with public health and economic survival. In fact, consuming water with nitrate levels close to or higher The European legal limit of 50 mg/L carries serious risks, and recent medical studies suggest that even much lower thresholds could be linked to oncological problems. Treating water to the millimeter is, therefore, a matter of life or death. On the economic level, as the newspaper highlights Informationfor the enormous hotel plant in Benidorm, opening the tap and letting water flow with total health guarantees “is not a secondary detail: it is a basic requirement to operate and to maintain the trust of visitors.” In addition, the system must be able to withstand the onslaught of the weather. According to Alicante Plazathe ETAP faces extreme scenarios after episodes of torrential rains, when the water collected arrives with enormous turbidity due to the dragging of sediments. Given this, the plant adjusts its treatments in real time. “Our responsibility does not end with there being water; it ends when that water reaches the tap in perfect condition,” says Noelia Llinares, ETAP plant manager, in these media. Leaving behind traditional management. As detailed by Veoliathe answer is in technology. A digital ecosystem has been deployed in Benidorm that includes network-wide sensors, leak detection algorithms and remote control systems. This has allowed the milestone of reducing water losses in the network to minimum levels of 5%. To support this burden, ETAP itself already received a powerful injection of more than 9 million euros in its last major expansion in 2010. But the cycle does not end at the sink. The WWTP works under a strict circular economy philosophy: used water is not waste, it is a resource. Today, 35% of the water that reaches the treatment plant is already reused, mainly for agricultural irrigation. And there is an extra factor that adds complexity: wastewater treatment plants are electricity devourers. To counteract this, María José Martínez, head of the WWTP, details that the facility uses byproducts such as biogas or sludge to generate its own energy. “The objective is clear: for the plant to become increasingly self-sufficient and for its environmental footprint to be as small as possible,” says Martínez. The next challenge: squeeze regeneration. Behind all this there is an ambitious project underway: the Regenerated Water Master Plan. The short-term objective is to take advantage of up to 2 additional cubic hectometers of regenerated water for purely urban uses, alleviating the suffocation of conventional sources and reinforcing the network against drought. Benidorm has empirically demonstrated that the high numbers of mass tourism and water sustainability are not antagonistic concepts, but rather necessary allies. In a context marked by climate change, the experience of the city of Alicante provides an inescapable journalistic and vital lesson: intelligent water management is no longer a simple competitive advantage or a green slogan. It is, purely and simply, a question of survival. Every drop counts, from the moment it is dammed until, thanks to engineering, it is regenerated to start again.

There is a secret outpost in a desert in Iraq to bomb Tehran

by

During the Gulf Warseveral Bedouins in western Iraq began to see helicopters and military convoys appear and disappear in remote areas of the desert where there was apparently nothing. Years later it was learned that many of those areas had been used as secret outposts and makeshift runways for Western special operations far from any official map. An outpost in the middle of nowhere. He told it in an exclusive the wall street journal. The war between Israel and Iran has left images of missiles, bombers and attacks thousands of kilometers away, but one of the most surprising stories of the conflict has occurred far from the cameras, in the middle of the Iraqi desert. According to several sources cited by the mediaIsrael secretly set up a forward base inside Iraq to support part of its air campaign against Tehran. Apparently, the place served as a logistics center, a support point for special forces and a rescue platform for downed pilots, all just a few steps away. hundreds of kilometers from Iran and hidden in one of the emptiest and most difficult to control areas of the Middle East. The idea seems straight out of a military espionage movie: a clandestine enclave installed silently inside another country, protected from the air and prepared to intervene in a regional war without official recognition. The strategic importance of Iraq. The detail reveals to what extent the distance was one of the big problems Israeli operatives during the campaign against Iran. Bombing Iranian targets from Israeli territory involves traveling enormous distances, maintaining long flight routes and assuming constant risks for pilots and aircraft. Having an outpost in Iraq changed part of that equation. It allowed rescue teams to be brought closer, special forces to be deployed and an intermediate point from which to react quickly in emergencies. The presence of Israeli air force commandos trained to operate in enemy territory further suggests that the enclave was not simply a makeshift base, but an infrastructure designed to sustain complex operations behind the lines of conflict. The pastor who almost discovered it all. The story took on an even more surreal tone when the base was nearly exposed by something as simple as a local shepherd. According to the published informationa local man alerted Iraqi authorities after observing strange movements and helicopter flights in the desert. The Iraqi Army sent several units to investigate and there began one of the most delicate episodes of the entire operation. The soldiers advanced in Humvees towards the area at dawn and ended up under intense fire supported from the air. In fact, a Iraqi soldier died and others were injured. The extraordinary thing is that for weeks no one understood exactly what had happened there: Iraq denounced an unauthorized foreign operation, some media initially pointed the finger at Washington, and rumors began to circulate about special forces operating clandestinely in the desert. Only later did the possibility begin to emerge that Israel was defending a secret facility directly linked to the war against Iran. Invisible war within another war. Plus: the episode shows the extent to which modern conflicts are full of invisible layers that rarely appear in official statements. While the world’s attention was focused in ballistic missilesdrones and attacks on Iranian facilities, in parallel clandestine operations were carried out in third countries to sustain all this military machinery. I remembered the Journal that the western Iraqi desert had been used for decades these types of activities by American forces, from the wars against Saddam Hussein to operations against the Islamic State. The reason is simple: the region is huge, isolated, and sparsely populated, making it a perfect place to deploy hard-to-detect temporary outposts. The difference is that now the scenario was not a US invasion or an anti-terrorist campaign, but a regional air war in which Israel needed to operate at an enormous distance from its territory. The long shadow of the United States. Although sources assure that Washington knew of the existence of the Israeli base, the United States I would have avoided participating directly in the clashes that occurred around the enclave. Even so, the whole story once again shows the extent to which the US military infrastructure in the Middle East continues to condition any regional conflict. The bases, air corridors, intelligence and experience networks accumulated over decades of operations in Iraq have created an ecosystem that allows for this type of rapid and discreet deployments. In fact, his own rescue of an F-15 American aircraft shot down near Isfahan during the war demonstrates that both countries were operating simultaneously in an extremely complex theater, one where commandos, helicopters and rescue teams could move across several countries while officially many of those operations They didn’t even exist.

While everyone was looking at Hormuz, Russia has found a much bigger secret route. And drones do not stop arriving in Iran

by

During the Cold War, Western intelligence services came to suspect that some Soviet freighters that apparently transported grain or machinery were actually hiding military equipment and technology sensitive under false covers. The problem was that, once inside certain internal routes controlled by Moscow and its allies, tracking them became extraordinarily difficult even for the greatest naval powers on the planet. While the world watches Hormuz. For months, the Strait of Hormuz has become the perfect symbol of Western pressure on Iran: US aircraft carriers, oil tankers diverting routes, marine insurance fired and constant threats on one of the great energy bottlenecks on the planet. However, while all international attention was focused there, Russia and Iran have been consolidating a much less visible and probably much more uncomfortable route for Washington: the Caspian Sea. It The New York Times said the weekend. This enormous space of inland water in northern Iran, usually ignored in geopolitical analyses, is being transformed into a true strategic highway to move goods, drones, military components and technology away from the direct reach of the United States. The photo. The most revealing image came when Israel bombed the Iranian port of Bandar Anzali, in the heart of the Caspian, in one of the most significant attacks of its campaign against Iran. The target was not in the Persian Gulf or Hormuz, but hundreds of kilometers further north. It was a clear sign that real logistical warfare no longer revolves solely around the most famous strait on the planet. The route that keeps Iran alive. The importance of the Caspian for Tehran has grown spectacularly since the pressure on Hormuz intensified. Russian and Iranian ships now transport wheat, corn, sunflower oil, animal feed and all kinds of of essential supplies who previously arrived via more vulnerable routes. Four Iranian Caspian ports are working at full capacity to absorb this growing traffic, while Moscow has begun to redirect millions of tons of goods that previously crossed the Black Sea. It turns out that the true strategic core is not in the cereal. According to US officials, Russia is using that route to send drone components to Iran to help it rebuild part of the arsenal lost during the last fighting with Israel and the United States. The relationship is especially symbolic because for years It was Iran that supplied Russia with Shahed drones for the war in Ukraine. Now the flow has partially reversed: Moscow manufactures its own versions under license and returns technology, components and military expertise to Tehran using the Caspian as a protected corridor. A perfect sea to avoid sanctions. The great advantage of the Caspian for Russia and Iran is that it is an extraordinarily difficult to control from outside. Unlike the Persian Gulf, where the US naval presence dominates much of the maritime traffic, in the Caspian they can only operate the five coastal countries. The United States cannot intercept ships there or impose direct blockades. Furthermore, a large part of the ships sail with transponders offdisappearing from satellite tracking systems and feeding an increasingly opaque network of “ghost ships.” In fact, Western analysts describe the Caspian as the ideal place for discreet military transfers and sanctions evasion. Dark shipping traffic has skyrocketed since Russia’s invasion of Ukraine, and both Moscow and Tehran have perfected methods to hide real shipments, routes and operators. It is no coincidence that Ukraine attacked the Russian port of Olya in 2024, accusing it of being a logistics center for the transfer of Iranian drone components. Nor that Israel Bandar Anzali will hit. Everyone seems to have understood that a logistical rearguard is being built there that is much more resistant than it appears. Moscow’s strategic obsession. Plus: for the Kremlin, the Caspian is not just a temporary solution derived from sanctions or the war in Ukraine. Russia and Iran have two decades imagining a gigantic trade corridor that connects the Baltic with the Indian Ocean, crossing Russia, the Caspian and Iran to avoid routes controlled by the West. The project includes new portsrailway lines and renewal of aging fleets, although many of these plans remain on paper due to lack of resources and the geographical difficulties of the Caspian. Still, the war has accelerated the strategic logic behind that idea: creating an alternative system of commercial and military circulation outside the reach of Western sanctions. For Putin, furthermore, the balance is delicate. Needs to support Iran as a regional ally and military partner, but do so in an all-too-visible way could deteriorate even more so its relationship with Washington and with several Arab countries important for Russian energy trade. The Caspian offers precisely that: sufficient support, but far from the media and military focus that Hormuz dominates. America’s great blind spot. Much of the Western concern arises from a very uncomfortable feeling: for years, the Caspian hardly occupied any space in American strategic planning. Experts in Washington recognize that the region functions almost like a black hole diplomat divided between different military commands and bureaucratic departments. Thus, while the world observed aircraft carriers in the Persian Gulf or drones over Ukraine, Russia and Iran took advantage of an immense, opaque and difficult to monitor geographic space to weave a logistics network that connects both conflicts. The problem for the United States is not that the Caspian completely replaces Hormuz, because it cannot do so, especially in massive oil exports. The real problem is that even under extreme military pressure, sanctions and naval blockades, Iran continues to find ways to stay connectedrearm and receive outside support. And each drone, each component and each shipment that silently crosses the Caspian reinforces an increasingly evident idea: while everyone was looking at the Strait of Hormuz, Russia and Iran they were building an alternative route much more difficult to stop.

We believed that the secret to rest was sleeping eight hours. A study has shown that we forget a big element

by

One of the mantras most repeated ad nauseum in the field of health is related to the need to sleep at least eight hours nightly. A goal that has been widely studied with the repercussions that failure to meet it may have. But now we have seen how the regularity in sleep is a much more powerful preacher of long-term health than mere duration. It’s when you sleep. Although we had very ‘glorified’ how much sleep we have to, trying to make up for lost hours on the weekendthe reality is that the important thing is to have good consistency, as is the case with many other processes. The regularity. The scientific consensus on this paradigm shift is gaining strength, and the last major proof is published by the National Sleep Foundation with an article that points to this regularity as one of the most forgotten components of our nocturnal habits. The key here lies in the internal clock, since we must remember that the time of waking up and early exposure to natural light is what activates our internal system with the cortisol release. In this way, by maintaining a constant reference, we ensure that critical biological processes, from hormonal secretion to body temperature, are regularized. When we don’t respect it. Just like when we travel to another country and we follow schedules very different from ours, the same thing happens here. We have the classic situation on the weekend, where we go to bed late and get up two or three hours later than usual, and surely the feeling when we get up is exhaustion. This is what is now known as ‘social jet lag’ or ‘Monday jet lag’, responsible for that mental fog, lack of alertness and low cognitive function with which we start the week. A shield. Unlike total sleep duration, regularity is a direct marker of the integrity of our circadian system, since when the internal clock and the demands of the environment become out of sync, known as chronodisruption, the body suffers. Just like when we travel between countries or experience time change. Here, a study published in Health Data Science HE dedicated analyzed more than 88,000 adults in the United Kingdom and found that irregular sleep patterns are associated with a greater predisposition to suffer from up to 172 different diseases. In fact, actigraphy studies have shown that intra-individual variability in our sleep hours is a direct marker of all-cause mortality, so trying to accumulate hours on Saturdays and Sundays not only does not save the furniture, but it puts us at risk. The impact of irregularity. In this sense, a linear relationship can be seen between sleep instability and the risk of suffering a cardiac event. But trying to “compensate” for tiredness on the weekend also results in worse insulin sensitivity and ends up altering glucose metabolism, which causes the bill to be quite expensive in the long run. Furthermore, the lack of a clear sleep routine causes a chronic pro-inflammatory state. This alteration compromises our immune response to pathogens, worsens the regulation of autoimmune diseases, and decreases the ability of our cells to repair themselves and eliminate metabolic waste. In summary, following set hours of sleep is essential if we really want to have optimal results in our daily lives.

the secret is in the hidden map of the nose

by

We have known for decades how what we see, what we hear and what we touch works. Science has been mapping these senses for a century, so that each sensory signal has a known direction, a path traced from the organ to the brain. A couple of examples: this retinal map either east of the cochlea. There was one pending subject: smell. Not because no one had looked for it but because the olfactory system has enormous complexity: more than a thousand different types of receptors and twenty million neurons in the nose of a mouse. A biological chaos that a Harvard research team has managed to draw a map. What the map says. The scientific team has discovered that olfactory neurons are not distributed randomly in the nasal cavity, but rather form a spatial code based on overlapping stripes organized by the type of receptor and distributed from the upper to the lower part of the nose. This pattern is practically identical in all the animals studied, so it is a conserved and reproducible biological architecture. The most surprising thing is that this banding arrangement is a mirror of the map of the olfactory bulb in the brain. That is, there is topographic continuity: the position of a neuron in the nose determines exactly which area of ​​the brain it will send its signal to. This means that the brain “reads” odors based in part on the geographic location of the cell that detected the molecule. havard Why is it important. Because it is the missing piece to understand neuroplasticity and the regeneration of smell. In practice, because the loss of smell currently lacks effective treatments: by knowing the original design of the system, researchers can now understand why connections fail after trauma or a viral infection, something that revealed COVID-19. If the architecture of the system is not understood, regeneration goes blindly. As Sandeep Robert Datta, a neurobiologist at Harvard’s Blavatnik Institute and principal investigator of the paper, points out, without understanding this map, attempts to develop new treatments are doomed to failure. Context. Mammalian olfaction is a complex system. In the case of the mouse, it has 20 million olfactory neuronseach expressing one of more than a thousand different receptor types. To get an idea, human color vision is only supported by three types of photoreceptors. This complexity meant that for decades science tended to associate the distribution of receptors randomly. Linda Buck and Richard Axel discover olfactory receptors in 1991 it earned them the Nobel Prize in medicine in 2004but that told us what detected the odors, not where or how they were organized. The good news is that with the advances in molecular biology today it is possible to analyze individual cells in their original position using techniques such as spatial transcriptomics. How have they done it. The Harvard team analyzed approximately 5.5 million neurons from more than 300 mice by combining two techniques: single-cell sequencing to know which receptor each neuron expresses and spatial transcriptomics to know exactly where it is located in the tissue. The study also identified the mechanism that builds that map: retinoic acid. By manipulating the chemical gradients of retinoic acid during embryonic development, they observed that the stripes of these receptors shifted, confirming that this acid functions as a kind of molecular GPS that tells each neuron where to position itself and which receptor to express. Yes, but. The first major limitation of the study is evident: it was done in mice, so as the research team itself acknowledges, they still do not know if the same organization applies to humans. Although the olfactory system of mammals is mostly conserved, humans have significantly fewer functional receptors (approximately 350 compared to more than 1,000 in the mouse) and a different nasal anatomy, so the existence of these stripes in humans still needs to be validated experimentally. Furthermore, although the map explains the wherestill does not fully explain the because of that specific order. We do not know if the stripes are grouped by the chemical structure of the odors or by their biological relevance, for example the smell of food versus odors of danger. Resolving what logic obeys that order is the next big challenge. In Xataka | We have been wondering for decades why Neanderthals became extinct.
