Between Tenerife and Gran Canaria hides an underwater volcano called ‘Enmedio’. The CSIC has just detected activity for the first time

by

Under the waters of the Atlantic, about 80 kilometers southwest of Tenerife and Gran Canaria, hides a colossus that we often forget about. Is called ‘Enmedio’, a name that has quite a joke behind it, but which is nothing more than an underwater volcano with a base of 3.5 kilometers and whose summit is 1,625 meters deep. And although it has been there for a long time, now a scientific team has detected for the first time signs of hydrothermal activity in its depths. A decade. It has not happened overnight, since the team of geologists has spent almost ten years collecting multidisciplinary data driven mainly through the VULCANA project. And the results of the measurements made between 2015 and 2024 now have ended up published in the magazine Bulletin of Volcanology. Here, through oceanographic campaigns that combine high-resolution bathymetry, seismic and geochemistry, scientists they have managed to confirm what until now was only a suspicion: the volcano has an active circulatory system. What have they found? What the team has confirmed with all this information is that there is low-temperature hydrothermal activity at this location. In simple terms, we can now see that the volcano is releasing fluids through a series of fractures and a depression that is in your franc. Although this does not mean that it will erupt in the next few hours. In order to make estimates, it was decided to analyze the water in the vicinity of the volcano, and here the instruments recorded thermal anomalies of up to 0.5 ºC above normal. That is, the water around the volcano was hotter and was also loaded with nutrients such as ammonium or iron oxide, which causes biological alterations in the rocks in the area. There is no rash. Logically, when we read ‘volcanic activity’ and ‘Canary Islands’ in the same sentence, it is inevitable to think about volcanic eruptions such as that of Cumbre Vieja in La Palma, and even more so taking into account the recent earthquakes in the area. However, the CSIC has been quite categorical in this regard, pointing out that this detection does not indicate an imminent eruption and has no relationship with the recent seismic swarms recorded in the area around Teide. A paradise. In this way it is an endemic and latent process. In fact, these hydrothermal vents are excellent news for deep ocean biodiversity. To understand it, we can look back to see how the Tagoro volcano ended up fertilizing the post-eruptive marine ecosystem. Now, Enmedio’s fluids act as a chemical engine that influences the composition of the local ocean and feeds communities of microorganisms that thrive in the most extreme conditions of the seafloor. And although the Enmedio volcano is not a new discovery, this first evidence that it “breathes” marks a before and after in volcanic monitoring in Spain. It demonstrates that under water, more than a kilometer and a half deep, the Canary Islands continue to be an incomparable natural laboratory that, thanks to science, we are beginning to understand better than ever.

The Adamuz accident has plunged demand for the AVE by 30%. It is a fact that hides something worse: mistrust

by

The high-speed accident in Adamuz (Córdoba) has turned the Spanish railway upside down. Closures, speed restrictions and a loss of credibility in the service have directly impacted the sales of the three companies that operate on Spanish roads. And it has translated into data: a 30% drop in sales. The data. Demand for high-speed trains has fallen by 30%, according to data collected by Trainlinea railway ticket price comparator that operates in our country. The information was released by Pedro García, its general director in Europe and Spain, at an event organized by the company this week. According to this platform, the demand for banknotes has fallen by 30% in the weeks following the Adamuz accident (Córdoba) in which 46 people died after an Iryo derailed and, still under investigationthe subsequent crash and derailment of an Alvia that was traveling in the opposite direction. No trust. We could say that it hints at it but it is almost a cry: the customer is distrustful of high speed. It is not only a question of security, the drop in demand is undoubtedly influenced by speed restrictions that have been imposed and the cancellations late in the day between Madrid and Barcelona. It must be taken into account that, in just over a month, we have had the following schedule on the Spanish railway lines: Later. In the current state of high-speed lines, only one thing is clear: the train is going to arrive later. First of all, because Adif is reviewing all avenues and that requires, for example, In Madrid-Barcelona, ​​25 minutes have already been added by default to the journey. And that is in the best of cases. Because as reported by a train driver Xatakathose who drive the trains have the power to stop the train or move more slowly if they consider that the tracks are not safe or, at least, not at maximum speed. Their repeated complaints have led to temporary speed limitations that have been activated and deactivated but, ultimately, yours is the last word. This situation has been experienced with the reopening of the Madrid-Seville line. The driver, passing through the Adamuz section He stopped the train thinking that something was happening on the premises.. Then it turned out that, simply, confusion had arisen due to repairs carried out. to the plane. This distrust has caused a transfer of passengers to the plane. And the thing is that, especially companies, have been putting aside the use of the train for daily trips between Madrid and the large capitals of Spanish provinces. Especially in the Madrid-Barcelona route, where business use of the train was very high, demand for air travelers skyrocketed to the point that Iberia capped dynamic prices at 99 euros. The Ombudsman even asked the CNMC to study the price increases that were experienced in the following days in airlines and car rental companies. The rise in demand for aircraft between Madrid and Barcelona has been such that Vueling has returned to the Air Bridgea route that had abandoned in a movement where, without a doubt, The arrival of Ouigo and Iryo on Spanish roads had influenced. And an impact on the accounts. The combo of cancellations, high-speed restrictions and insecurity in arriving at the agreed time has caused a hole in the accounts of the large railway companies. According to theEconomistalready in January 2025 the losses were recorded at more than one million euros per day if only the cut in the southern corridor was taken into account. In The reason They raise the impact to a loss of 109 million euros in Malaga tourism alone. Losses that are yet to be quantified for companies but that arrive at a bad time, just when Ouigo and Iryo aspired to make money in our country after completing its landing phase. Photo | Samson Ng.

La Niña is going to be meteorologically “less intense” than we expected. And that actually hides a problem.

by

There is a 55% chance that the world will cross the La Niña thresholds in the coming weeks. And although The World Meteorological Organization insists that it will probably be a weak and brief episode, that does not mean that it will not cause us problems. Many problems, in fact. First because it is going to catch us with a changed pace. When world meteorological agencies indicate that La Niña will be low in intensity, what they are also doing (often inadvertently) is telling authorities that it won’t be that bad. And that is technically true, but socially speaking it is a mistake. WMO A global event… Let us remember that, with the exception of the seasons, ENSO (of which La Niña is a phase) constitutes the most important source of annual climate variability from all over the planet. It is true that the cold phase usually has less impact than the warm one, but the teleconnections of The Girl They are still huge and so is their impact. …with an impact worthy of its size. In fact, under “normal conditions”, with a 55% chance of it arriving this quarter, many countries would be preparing for its consequences. Above all, because, under “normal conditions”, there are many: For example, in the southeast of the American continent temperatures become warmer than normal. Likewise, they get colder in the Northeast. Less rainfall than normal is expected in Ecuador and Peru, and torrential rains are expected in Northeast Brazil. In Mexico, it is common for La Niña to cause (or make more intense) drought in the north and center of the country, while increasing torrential rainfall in the Pacific, the southern Gulf of Mexico and the Yucatan Peninsula. In Spain, for its part, it is usually synonymous with less rain. In other words, bad news. But we are not in “normal conditions.” As I say, the WMO messages they are precise; but they act as confusing signals: the administrations are not preparing. And that, whether we want it or not, can turn even the most lukewarm of Las Niñas into thousands of problems on a regional scale. But we must also take into account the global scenario. Because, as the WMO also points outLa Niña may bring slight global cooling. However, this should not motivate a reduction in efforts against climate change: the accumulated warming is so great that temperatures will most likely remain above average. That is, climate change is still underway. And, unlike other years, not even La Niña can do anything to contain it.

The popular hair drug hides a big problem behind depression

by

Finasteride has long been a popular solution for the treatment of androgenic baldnesswhich has long been a very popular solution to stop hair loss. However, behind its apparent cosmetic success hides an alarming reality that has taken more than twenty years to receive greater attention: a significant association with depressionanxiety and suicide. The analysis. Published in the Journal of Clinical Psychiatry by Professor Mayer of the Hebrew University of Jerusalem, systematically reviews the accumulated evidence and exposes what he describes as “a systemic failure of pharmacovigilance.” The study concludes that both the drug’s manufacturer, Merck, and regulatory bodies, such as the US FDA, failed to take relevant action despite growing danger signals about serious health problems. The evidence. Although concerns about depression associated with finasteride arose as early as 2002, it was not until the last decade that the evidence became overwhelming following studies done after the product was marketed. Brezis’ analysis is based on eight large independent studies published between 2017 and 2023, which used two main methods: disproportionality analysis in adverse event reporting systems and analysis of massive health registry databases. The results. The study carried out in countries such as Sweden, Canada and Israel points to very consistent results: the use of finasteride is associated with a significantly higher risk of developing depression, anxiety and suicidal behavior. All of this with a good statistical significance that shows that it is not due to chance. The human cost of this two-decade delay is devastating. The report estimates that, globally, “hundreds of thousands of people may have suffered from depression, and hundreds, or even thousands, may have died by suicide.” The data. One of the main reasons why it took so long to react was the massive under-reporting of cases. In 2010, the FDA was already discussing internally the possibility of including depression as a side effect, but noted that reported suicides were lower than expected in such a large user population. Brezis’ analysis puts figures on this discrepancy: For 2011, with a base of 4.6 million users worldwide, between 6,440 and 12,880 suicides were expected over a period of 10 to 20 years. However, only 18 cases had been reported to the FDA system (FAERS). By 2024, reported suicides amounted to 320, compared to the 19,320 that would be expected over a 30-year period. FDA inaction. The report is especially critical of the manufacturer and the regulator. Despite suspicions, none of the eight studies analyzed were conducted by Merck or requested by the FDA. This is striking, since Merck itself had validated in 2006 the usefulness of the pharmacovigilance tools used in these investigations, concluding that they had “sufficient sensitivity and specificity.” For its part, the FDA was disconcertingly slow. In 2011 it recognized depression as an adverse effect and in 2022 it added suicidal ideation, but not as a formal warning on the label. It took the agency five years to respond to a citizen petition requesting the drug be removed from the market. Internal FDA documents from 2010 show entire sections redacted as “confidential,” hiding key data about the drug’s safety. The case in Europe. In addition to the report issued by the FDA, the European Medicines Agency (EMA) has also launched an alert following its research on this same medication and suicidal tendencies. This is something that the Spanish Agency for Medicines and Health Products (AEMPS) has collected on its website, pointing out that from now on the packages of finasteride 1 mg will include a patient information card with the aim of reinforcing these warnings. In France they wanted be much more critical with the recommendations made by the EMA to confront this serious problem. Specifically, they have pointed out that the introduction of this alert card or the dissemination of a letter to professionals is not enough. Especially considering that the latest recommendations made by the regulator have not reduced the incidence of suicidal ideation in treated patients. Because. The relationship between finasteride and mood disorders is not a simple correlation, but has a plausible biological basis. The drug inhibits the enzyme 5α-reductase, reducing the conversion of testosterone. This process also decreases the synthesis of brain neurosteroids, such as allopregnanolone, which are crucial for mood regulation. For some users, the effects do not go away when they stop treatment. The so-called “post-finasteride syndrome” describes severe neuropsychiatric symptoms that persist for months or years after stopping the drug. Call to action. Brezis emphasizes that, as it is a medicine for a cosmetic indication, the balance between benefit and risk is radically different. “It wasn’t about a life-or-death medical need. It was about the hair,” he emphasizes. Images | Nik Shuliahin 💛💙 In Xataka | A natural, safe and already approved sweetener for consumption: the new and unexpected solution against baldness

In reality, it hides elevators that take boats up through the heart of a mountain

by

Let’s imagine a ship that, instead of descending through locks, rises up a mountain inside a chamber of water. That’s exactly what happens in Goupitana dam in southwest China where the difference in level between the reservoir and the river reaches almost two hundred meters. To overcome this gap, engineers designed three consecutive elevators capable of transporting boats of five hundred tons. It is a system that combines the scale of a hydroelectric dam with the precision of a clock and has once again transformed the Wu River into a continuous navigable waterway after more than twenty years of interruption. For years, the Wu River was a natural highway for Guizhou. From its mountains, barges descended towards the Yangtze loaded with minerals, cement or fertilizers. Everything changed with the construction of large hydroelectric dams in the early 2000s: the reservoirs generated power, but completely cut off shipping. Between 2009 and 2016 there was no continuous navigable passage in Goupitán: the goods had to be unloaded before the damget on trucks, go around the mountain and embark again upriver. That transshipment could take one or two days and cost more than 20,000 yuan per barge, an obstacle that discouraged river transport and made the local economy more expensive. Three elevators, the same river and a mountain in between Goupitan is not one boat lift, but three that work in series to allow the river to become navigable again. Each one overcomes a part of the unevenness and, between them, a connection channel It combines tunnels dug into the mountain and an aqueduct suspended over the valley. According to the Guizhou Department of Transportationthe group forms a route of just over two kilometers where they can operate barges standard five hundred tons. The design distributes the total elevation into three sections, with a fully balanced central level and two submersible-type ends. This system became the first in the world in applying three consecutive elevators within the same project and in achieving an unprecedented single level elevation of 127 m. The investment was around three billion yuan (about 400 million euros), and the infrastructure can move almost three million tons of cargo per year. The operation of Goupitan is based on a principle as simple as it is effective: that of balance. Each ship enters a chamber filled with waterso that the total weight hardly changes when the boat floats inside. This almost constant mass is compensated by counterweights and steel cables that raise and lower the drawer with a precision of centimeters. The first and third elevators are submersible type, with the box that sinks into the water to equalize levels, while the central one uses a fully balanced system, similar to a conventional elevator but on a monumental scale. Electric motors drive the drums that wind the cables, and the entire operation is controlled by sensors that measure tension and position in real time. If they detect a deviation, the system stops immediately. Three years after the hydroelectric dam came into service, navigation works began. For almost ten years, the place was transformed into an engineering laboratory. Navigation tunnels had to be opened under the rock, metal towers had to be erected and the steel caissons had to be assembled by hand inside the valley. In June 2021, a boat five hundred tons completed the journey of the three elevators, marking a milestone. In 2023After the latest inspections, the Ministry of Transportation declared the system operational and handed it over to the provincial authorities for commercial exploitation. Once in service, the system operates as a synchronized chain. The complete transit through the three levels takes approximately 38 minutes, according to official data. The process is automated: sensors, cameras and a central control room manage the gates, water pressure and cable movement. The impact was noticeable from the first day. In November 2021a convoy of fourteen barges carrying seven thousand tons of phosphate completed the journey of the three lifts and marked the official return of navigation on the Wu River after more than twenty years of interruption. Since then, river traffic has established itself as a real alternative to road transport, with lower costs and a much smaller environmental footprint. For Guizhou, a landlocked provincethat difference is strategic. The Wu River connects with the Yangtze and, through it, with the port of Shanghai. The reactivation of traffic makes it possible to export minerals and construction materials directly from the interior and, in turn, receive raw materials without depending on land transportation. Maintenance tasks are constant. Each elevator undergoes daily inspections and more in-depth checks every few weeks. The technicians, for their part, have received specific training to operate the machinery. Keeping such a structure in balance requires the same precision as building it and close operational coordination with the exploitation of the reservoir. Goupitan’s system changed the map of boat lifts. Until its entry into operation, the reference was the elevator the Three Gorges Damwith a difference in altitude of 113 meters. In Europe, the Strépy-Thieuin Belgium, with 73 meters, and the Falkirk Wheel Scottish, a rotating structure of 35. None approaches 199 meters that covers the whole of China nor the 127 of its central section, the highest individual elevation recorded to date. The Goupitan boat lift is nestled in one of the most rugged landscapes in southwest China. The river meanders between forest-covered mountains and villages scattered on the banks. Official photographs taken with drones show the real scale of the complex: three gigantic chambers connected by tunnels and aqueducts, with ships that appear tiny as they ascend. The contrast between industrial precision and the geography of the valley explains part of the visual impact of seeing them in motion. Although its purpose is strictly logistical, The place has attracted the attention of curious people and visitors. From the road that borders the reservoir and the access to the damand get panoramic viewsand media coverage has popularized aerial images of the maneuvers.

US aviation hides something

by

Two events that occurred in the United States, separated for a few days and just a few hundred kilometers between them, look like pieces of the same puzzles: the silent advance of Pastive aviation and the permanent struggle to maintain the technological advantage in a world where heaven remains the decisive scenario of military superiority. An enigmatic accident. On September 23, 2025, an apparatus of 432º Wing of the United States Air Force He crashed In the Nevada desert, a few kilometers from mythical area 51. The Air Force confirmed that there were no victims or material damage, but the striking was the subsequent reaction: the FAA imposed restrictions Temporary to airspace under the argument of “national security”, something reserved for episodes that involve extremely sensitive material. The 432th wing, based in the Creech base, operates mainly MQ-9 Reaper dronesalthough it also houses squadrons responsible for new generation poachers such as RQ-170 Sentinel. The official silence about which model was involved fed suspicion that what happened was not an ordinary accident, but the loss of a system linked to black advanced development programs. Map that shows the approximate location of the coordinates of the center of the TFR of “National Security” that was in force between September 23 and October 1 Manipulation in the place. What is most baffled is that, after cleaning and removal of remains, researchers discovered Signs of manipulation in the area: an inert training device and a plane panel of unknown origin had been placed there after the accident. The Air Force and the FBI They opened an investigation Joint to determine how and why these objects appeared, although officially the area was under surveillance until September 27. That the authorities publicly recognize this detail is atypical, which leads to think that the possible alteration of the sinister place is related to the protection of sensitive information. TO Observer eyesthe fact that someone could add external pieces in a newly insured site raises doubts about the safety of operations and what was attempted to cover up or, on the contrary, to evidence. The only official image of the RQ-170 that the US Air Force has published to date. The drone is seen at the Andersen Air Base of Guam The background of the programs. The proximity to area 51 and the involvement of a wing like Creech’s, where they concentrate so much conventional drones as The most secretThey reinforce the idea that the lost apparatus was not a simple reaper. The MQ-9 They have suffered accidents in everyone And the Air Force has reported them without major mystery, even on stage of active operationsso it is unlikely that a routine sinister had deserved an air closure and the intervention of the FBI. The hypothesis that it was An experimental prototypeof an advanced sensor or a new poaching configuration would explain the secrecy and inconsistencies. The Groom Lake History and of its ultrasecretos programs (from the U-2 and SR-71 Even modern poaches projects) serves as a backdrop to an incident that seems to enroll in the same tradition of invisible evidence for the general public. Another strange object. Almost at the same time, at the Lockheed Martin test center in Helendale, California, He filmed A dark object with rhomboidal formsimilar to a blanket or a steering wing, mounted on a pylon in full radar section test. The images They showed a surface with bluish areas and proportions other than those of any known plane, which gave rise to speculation about whether it was a fuselage module, a partial design of future furtive aircraft or a simple calibration article. Skunk Works It has been using this installation for decades to validate materials, angles and configurations aimed at reducing detectability, and engineers usually assemble the inverted models to minimize unwanted reflexes of support and land. The fact that the test will be carried out in broad daylight suggests that It was not a classified prototypebut part of the constant research flow that feeds next -generation programs. The weight of observation. Plus: the images disseminated from Helendale revived the debate on The limits of observation from public land and the thin line between civil curiosity and operational security. The apparent permissiveness towards the presence of observers, and even the appearance of a reaper drone flying over the area, indicate that the test did not imply especially sensitive material. In contrast, the hermeticism of accident in Nevada It shows how the level of secrecy varies according to what is at stake: an experimental object without strategic value can be exposed in open evidence, while the fall of an apparatus linked to X programs requires absolute control of the narrative. If you want, both episodes reflect how the Armed Forces and the industry manage the thin border between showing technological advances and protecting developments still too delicate to come to light. Two pieces of the same puzzles. The temporary coincidence between the accident near area 51 and the appearance of mysterious object In Helendale reinforces a theory: the perception that the United States is immersed in an accelerated cycle of furtive essayssome more than others, and therefore possibly “hide.” The contrast between opacity in Nevada and the relative opening in California points to that in one case a highly sensitive prototype was lost and in the other it was a routine technical trial, although both respond to the same objective: to improve the next generation of invisible aircraft by radar. Be that as it may, the combination of manipulation at the site of the incident, involvement of the FBI and new forms captured in Skunk Works facilities makes it clear that US secret aviation continues to advance in silence, offering the public just fragments of a technological mosaic that, piece by piece, suggests developments with potential to alter global military balance in the coming decades.

The creator of Chatgpt has realized that the Internet is full of AI. His sudden concern hides something else

by

Sam Altman is worried online. A few days ago said in x that the Dead Internet Theorybut now it seems to him that many Twitter accounts are controlled by Bots. The thing was not there. He also criticized that some posts in Reddit seem written by an AI. His messages have unleashed a wave of answers that remind him of something obvious: he has played an important role in all this. In addition, what presents us as a genuine concern would have other hidden reasons. Dead Internet. The first message arrived last week, as they say in Futurism. In him, Altman said he was starting to be taken seriously This theory which states that the current Internet is dominated by bots, AI and content generated by algorithms, instead of humans. Their answers were filled with mockery, such as This user who answered by imitating the chatgpt style or those that sent him This meme With the text “we are trying to find the uncle who did this.” The publication has 3,000 responses and many of them point to him as one of the culprits that the Internet is full of bots and content generated by AI. A real problem. Although the concept of the dead internet is a conspiracy theory, the problem of the bots is very real, and if not tell Elon Musk when he bought Twitter. According to Data from the Cybersecurity Company imperviousin 2023 49% of the Internet traffic were Bots. With the arrival of AI the thing has worsened and In your 2024 report They confirm that the figure had increased to 51%. In other words: there is more bots traffic than humans. In addition, 37% of these bots are used for malicious purposes such as the creation of news and false content. And not to mention Ai Slop that is flooding the network. “It feels Fake“ Returning to Altman, yesterday He shared his sensations After reading the Claude Code Subnetditin which several users praised Codex’s capabilities, the OpenAI code assistant, almost as if it were the best that has happened to them in life. Although it is something that benefits its product, Altman said they seem posts written by an AI and that, both Twitter and Reddit, they feel very false lately. Among the possible reasons, Altman believes that people are starting to speak as if they were IAS, although obvious that the AI ​​models have trained to sound like us and, more specifically, Reddit itself has been used in training of many of them. Altman also mentions a possible case of “Astroturfing“, a tactic that is used to generate artificial opinions that are passed as real to give a false impression of support or rejection of a product. Altman ensures that they have previously suffered it and that is why it is” very sensitive “with the subject. Hidden reasons. As they point out in TechcrunchAltman’s sudden obsession with the bots, the dead Internet and especially the Astroturfing It would have a goal: to sow doubt about the opinions issued about their products. With this, the idea that the wave of criticism of users after the launch of GPT-5 They were not real. Some Users in Reddit They also point to another possible reason: that the rumors of OpenAI’s social network Be true and what Altman is looking for is to subtract credibility to his competitors.

There is a ‘good’ fat that hides a secret to aging better and being fit. It only remains to get the pill

by

Aging is inevitable, and with it it comes A progressive loss of physical capacity that causes it to be more difficult to walk or stand up. This makes Stay fit It becomes much more difficult and therefore the resistance begins to decline. But … what if this decline can be slow down? This is precisely what science is focused on. Fat as anti -aging. Researchers at the Rigers New Jersey Medical School They have discovered That a special type of adipose tissue, known as brown fat, could be the key not only for healthier old age, but also Improve physical performance. A study of great relevance, since it can open a new route in the anti -aging field. The team that has led this research has been able to identify an unusually powerful form of this ‘good fat’ in mice, which not only Increased his life expectancybut improved its exercise capacity by an impressive 30%. Now, the race has begun to be able to replicate these same effects in humans through a drug. Not all fat is bad. When we think of fat, the White fat or white adipose tissue. Its main function is to store excess calories in the form of triglycerides and is the one that can bother us aesthetically throughout our lives. Although in essence it is a large energy deposit. But, nevertheless, there is another type of fat that is much more interesting: brown fat or Brown adipose tissue. Unlike white, brown fat is specialized in burning calories to generate heat in a process called thermogenesis. This is possible thanks to the fact that their cells are full of mitochondria, which are the organelles that act as cellular power plants and that give it its characteristic brown color. In our life where we have more fatty fat in our body is when we are babies, since here it is crucial for Keep body temperature. But when we grow, the brown fat is lost until some cracks are around the neck and shoulders. But here the white fat is the one that dominates our body completely. One step further. Knowledge about brown fat already has a long journey in scientific literature. But it is now when this study goes further to point that it is linked to having a healthier longevity and with a much more appropriate physical exercise. How they knew it. To get to this conclusion, the researchers worked with a genetically modified mouse model to lack a protein called RGS14. The mice without this protein lived approximately 20% than their normal partners, and curiously the females lived more than the males in a pattern similar to that followed by humans. Even at the advanced ages, these mice avoided the typical signs of aging such as body atrophy, hair loss or the graying of the fur. But it does not stay here, since when submitting them to physical tests, the modified mice showed a 30% higher performance, both in distance traveled and in resistance. And all this because mice without RGS14 developed a dense and powerful brown fat than who expressed the protein correctly. The definitive test. To confirm that it was brown fat, and not another effect of genetic modification, scientists conducted a crucial experiment: transplanting the brown ‘supergras’ of mice without RGS14 to normal and healthy mice. The results were overwhelming. The mice that received this transplant improved their ability to exercise in just three days. On the other hand, when brown fat was transplanted from a normal mouse to another, an improvement was also observed, but much more and with eight weeks ahead to manifest its effects. Something that showed that the fat of the genetically modified mice was exceptionally powerful. Because? The mechanism seems to reside in an improvement in blood circulation. The indications suggest that brown fat promotes the creation of new blood cases in the muscles that improves the flow of blood and oxygen during exercise. The goal. Research suggests that this brown fat not only improves physical performance, but also protects against a series of ailments associated with age, such as obesity, diabetes, cardiovascular disorders and even cancer and Alzheimer’s. Vatner’s team is already working with collaborators to develop a drug that imitates the effects of this powerful brown fat, hoping to have a compound ready to be tested in approximately one year. But the idea is not only to increase life expectancy, but “healthy life expectancy.” That is, even if you live longer, these ‘extra’ years enjoy good physical and mental health. While we expect that future pill, there are techniques such as deliberate exposure to cold (the famous ice baths) that can naturally increase our brown fat levels. However, as Vatner points out, most people would prefer to take a pill to take an ice cream bath. Images | Tatiana Zanon In Xataka | Our brain has its own backup.

Its guided combines inertial navigation, correspondence of land or images, and positioning By Beidou satellite to achieve precision at the level of meters. It can attack both mobile and fixed objectives of high value, including command centers, logistics knots and key points to paralyze operations. Mobility and operational flexibility. Unlike the tests in common desert areas, the launch was shown in An urban environmentwhich, according to analysts, seeks to show that DF-100 can operate from unconventional locations such as cities, hindering its detection and destruction by adversary forces. Under that prism, this flexibility would allow to deploy it quickly and from unpredictable positions, reinforcing its value as a weapon to “hit and disappear.” Its ability to launch from multiple platforms and in varied environments increases the tactical options of the EPL and complicates the countermeasures enemy. Strategic context. We have Cash before: the public appearance of DF-100 It is part of a moment of growing global military competence and responds, according to experts, to the will of Beijing of Project strength and reaffirm its arms modernization. Although the EPL rocket force has recently been dotted with corruption scandalsthe demonstration emphasizes that their material abilities remain intact. The DF-100, the only land cruise missile capable of maintaining supersonic speed During the whole flight It reinforces the Chinese strategy to deny access and limit the projection of American naval power in the Western Pacific, positioning itself as one of the “master letters” of the Chinese arsenal in a possible confrontation scenario.

The subsoil of historical cities hides a great garbage vacuum. The problem is that you have to punch

by

Tony Soprano, from the great series’The soprano‘He was dedicated to garbage management. It may seem an exaggeration designed for fiction, but as usually happens, fiction surpasses reality. Base management It is a problem for half the world (more now than China decided to stop being our landfill) and move so much money that there is mafias moving from one country to another. In the search for solutions, the definitive company came up with a Swedish company to stop seeing cubes and garbage trucks through the streets: move waste from pipes. It is something that has turned medieval cities into the technological pinnacle of garbage collection. But the day -to -day life of the neighbors is something else. Changing the approach. It all started by chance. At the end of the 1950s, the Sollefte hospital in Sweden was investigating the creation of a central aspiration system to catch dust. One of the participants in the table was OLOF H.Hallstrom, director of Centralsug, the current Waste Waste company, and the idea arose: instead of a giant vacuum For dust, a giant garbage vacuum could be created. So They tell On its website, where they point out that the system was inaugurated in the hospital in 1961 and that it continues to work with many of the original pieces installed more than 60 years ago. But of course, if it works so well in a building, why not expand the network to an entire city? That is no longer so easy. Sollefte basements with garbage collection tubes A giant vacuum. First of all, you have to see how it works. Known as’Pneumatic garbage collection‘O’ Automatic vacuum collection ‘, AVAC from now on, is a giant vacuum connected to a multitude of underground pneumatic tubes. On the surface there are a series of nozzles that are designed for organic or plastic waste (the glass could damage the system) in which the bag is deposited with the waste and, thanks to fans that generate suctions of more than 60 km/h, travel through the tubes to a collection center. Example of one of these nozzles They are classified and loaded into trucks to transport them to their final location. This system reduces the use of trucks and their corresponding pollution, as well as Cubes in the streets. The most current systems include doors that are automatically open and cards in possession of citizens to activate the system. Modernizing historical cities. And that reduction of cubes and trucks circulating is something ideal for any city, but it seems key in locations with two profiles: tourist or old helmets of medieval cities. A clear example is Bergen, a Norwegian city founded in 1070 that is the second most populated in the country and has a historic center full of colorful wooden houses. It has fired several times and the garbage itself can be a focus of fire, so by safety and improve the helmet, they decided to bet on an avac type system. It is one of the 200 cities in the world in which this system has been installed and, as we read in The Washington Postthe diesel emissions Since the garbage trucks stopped circulating along their narrow streets. Among others, Leganés, Barcelona, ​​Barakaldo, Torrent, Vitoria-Gasteiz, Stockholm, Doha or Seoul have neighborhoods in which a pneumatic collection system is used, and in new construction complexes of some cities are also betting on it. Complex. The problem is what you can imagine: the system itself is expensive, but it is also a headache. In new neighborhoods, it is as simple as to pass one more pipe in the streets where there are already other pipes, but in Historical cities Or neighborhoods already built, bet on something like avac implies lifting the streets and performing a considerable work. Bergen’s example is clear. As they point out on TWP, since they made the decision to start building the system in the historic center in 2007, they have invested about 100 million dollars. There are years to finish connecting the entire network and estimate that the cost will be 30 million dollars. Terje Strom, responsible for waste management in the city, says it is “almost impossible.” Contextualizing the figures? It is almost the entire annual budget of the Waste Department. Collection Central in Konza Technolopis, Africa Gamification and penalty. But, leaving cost aside, user experiences seem positive. It is a system that simplifies the garbage, which eliminates full cubes and the truck transit. In Spain we have containersbut in other cities they work with individual cubes that roll through the streets and share the stamp. Not everything is perfect, since although there are no trucks, they do operators who are dedicated to unblocking the mouths when someone introduces something that should not. And beyond not seeing garbage trucks, there are two incentives for citizens. One is the gamification by application That tells us how many kilos we have deposited in real time and compares with the previous month. It also tells us how average we are, since there is a limit. In Bergen, to open waste mouths, residents bring their electronic key, which allows you to register how much discard and collect a rate according to the amount of non -recycled garbage they send to the incinerator. This penalty is something that It has also been seen in South Koreawith positive results regarding the increase in recycling. Not everyone is happy. Beyond installation costs, it seems the perfect system to manage waste. However, looking at what happens in Spanish cities in which these systems have been installed, we see that not everything is so beautiful. There are more than thirty cities that use this pneumatic collection, and in some Failures are reported that cause the tubes to be full due to pipes that do not absorb well. Tubes in a kind of garbage rooms in Leganés. The main problem for users is the diameter of the mouth. Image | Xataka It is something that causes bad odors, as users of … Read more
