“A microsecond lag in GPS could miss a moon landing by hundreds of meters”

by

The competition and space disagreements between the United States and China are one of the main geopolitical problems in 21st century science. We might think that this effort to be first only harms them, but in reality it can be a problem for anyone who enters the space race. There are many issues that serve as examples, although the most recent is the one that concerns lunar time. It has long been clear that there must be a lunar standard time, but The United States has decided to establish a and China another. The consequence is a weak satellite navigation system, which can affect anyone who wants to land on the Moon. At the moment, it seems that NASA is the most advanced in this regard, but it is possible that it will have to do so under Chinese standards, so the conflict, if they do not agree, is served. Two hours for one place. USA has agreed determine the lunar time under something called Coordinated Lunar Time (LTC). That would be the time under which the LunaNet satellites would work, a satellite system projected by NASA in 2019in order to control the first navigation system of our satellite. For its part, China has decided to establish the time according to the Lunar Time Ephemeris (LTE-440). This is the system with which both Queqiao-1 and Queqiao-2, the only two lunar relay satellites that are currently active, maneuver. They are designed for communications and would be the first step towards a lunar GPS system. Why is it necessary? Gravity is very different on Earth and the Moon. We know that gravity, in addition to generating attraction on bodies, also curves space-time. As a consequence, time passes more slowly the greater the gravity. And what does that mean? Well, basically, time passes faster on the Moon. Specifically, 56 microseconds faster. That means we can’t use the same time on Earth as we do on the Moon. Our natural satellite needs its own schedule. Be careful with the GPS. GPS systems work by signaling temporal signals measured by satellites. It measures how long it takes for the satellite signal to get from one point to another and, thus, the distance can be calculated. Therefore, it is very important that satellites and clocks work with the same time system. When traveling to the Moon, you should take into account how the satellites used by GPS measure time. But we have already seen that China and the United States do not agree on that. For now, LunaNet is nothing more than a project. The Chinese lunar GPS system too, but at least there are already satellites. Those from the United States have not been launched. Therefore, if NASA lands on the Moon without taking into account the Chinese time system, there could be problems. Just a microsecond of difference in lunar time can affect hundreds of meters away. That can be very dangerous in the face of a moon landing. China has already tried it. The Asian country is the only one that has landed a ship on the far side of the moon. Terrestrial radio systems do not reach this area of ​​our satellite. Therefore, this unmanned moon landing had complete dependence on Queqiao-1. It was proven to work, as the moon landing was a success. But of course, the ship was synchronized with the satellite time system. It is necessary to reach agreements. Sometimes these types of political disagreements make scientists quite lazy. They may want to reach agreements to work in a safer way. At the moment, NIST, which is the United States Standards Institute, is having conversations with the Purple Mountain Observatory (Zijinshan). This institution is one of the main managers of Chinese satellites, so its decisions are very important in the decision to use one time system or another. For everyone to achieve their goals, this time it would be necessary to work as a team. The grudges and competitions could end up delaying the space race for both sides.

the cities are no longer yellow

by

The astronauts who have been lucky enough to travel to space more than once in the last decade are privileged witnesses of a chromatic change on a planetary scale. From their vantage point 400 kilometers high, they have been able to see that the cities, previously faint spots of amber, now shine with an intense white light. It’s not a metaphor. It is the visible trace of one of the most rapid and widespread infrastructure transformations in recent history: the great replacement of public lighting. We have retired the old sodium vapor streetlights and massively embraced LED. This change, driven by regulation in favor of energy efficiency, has redrawn the night map of the Earth, a phenomenon that can be seen more clearly from space. The invention that earned a Nobel Prize in Physics. Old sodium vapor lamps, especially low-pressure ones, were monochromatic in nature. They emitted light in a very narrow band of the spectrum, resulting in that characteristic and ubiquitous yellow-orange hue that tinted our streets and skies. LED lights work in a completely different way. His breakthrough, which earned Isamu Akasaki, Hiroshi Amano and Shuji Nakamura the 2014 Nobel Prize in Physicswas the invention of the high-efficiency blue LED. By combining this blue LED with a phosphor coating, it was finally possible to generate a bright and affordable white light. This diode is not only more efficient (exceeding 300 lumens per watt, compared to 16 for an incandescent bulb), but it offers a much broader spectrum. Southern Europe in 2025 from the International Space Station. Image: Don Pettit The cities changed color. To the eyes of a night observer in space, cities have gone from being yellow to glowing bluish white. Milan is the paradigmatic case: it completed its transition to LED in 2015, and appears in an ESA comparison with before and after photos taken by astronauts André Kuipers and Samantha Cristoforetti. But it is by no means the only case. Los Angeles was a pioneering city: it ordered the replacement of 140,000 streetlights in 2009. Buenos Aires modernized its lighting with smart LED streetlights between 2013 and 2016. New York finished replacing 500,000 bulbs in 2023. Barcelona plans total remote management of public lighting by 2028. But India is the country that carries out the largest replacement in the world, with more than 13 million LED streetlights already installed. The b side of this transformation. Like any revolution, the LED has a dark side. Light is cheaper, so cities are not only replacing old streetlights, but also increasing the number of light points or their intensity. The result is that we are leaving a brighter planet, where it is most difficult to escape of light pollution. The statistics indicated otherwise, but it must be taken into account that light pollution is measured by satellites, and satellites are partially blind to blue light. This means that the actual increase in light pollution, especially that perceived by human beingsis much higher than official figures indicate. To make matters worse, blue light is the one that interferes the most with our biological clock, and can affect the quality of sleep, in the same way that disorients migratory birds and the moths. The future is adjustable. The solution is not to go back to sodium. The efficiency of the LED is indisputable. The key, as with any technology, is in its application. The next phase of this transition is not about changing light bulbs, but about installing smart streetlights. It is estimated that almost one in four streetlights will be smart by 2030. When connected, they can regulate their intensity depending on the time or traffic, detect faults in real time and collect environmental data. This remote management will allow one of the new lighting maxims to be applied: using only the necessary light, when and where it is needed. In parallel, other solutions have emerged to protect biodiversity, such as red light streetlights being tested in Nordic cities so as not to disturb the bats. and the idea of ​​bioluminescence as an organic way of generating light without any electrical consumption and with minimal environmental impact.

I explain how to do it, how to activate your privacy key and the obstacle I found

by

we may carry months talking about usernames on WhatsAppbut it is one thing to read about a feature that is coming and quite another to see it appear in our own account. This Monday, WhatsApp, from Meta, opened the reserve of identifiers before they can be used generally, and the first thing I did was try to get mine out of the way. At first I couldn’t do it, but a few hours later the option was already there. And then the interesting thing began: booking it was easy, choosing it not so much. In the earlier published article We already explained the scope of the function: usernames do not replace the phone number to create the account, but they do add a more private way to initiate certain contacts. This time the approach is more practical: what I found inside the application, what steps I followed to reserve my identifier and what detail forced me to change plans when I tried the most obvious option. How I reserved my username on WhatsApp In my case, the journey started from the main WhatsApp screen, in the bottom bar of the application. To the right of Chats the tab appears Youwhich is where WhatsApp groups access to the profile and various account settings. From there I entered Account and then in User namean option that already appeared in the menu. As seen in the screenshots, the path is not hidden, but it does require knowing where to look if we have not yet received a clear warning within the app. The next screen leaves little room for doubt about the status of the feature. WhatsApp does not say that usernames can simply be used, but rather that “they will be available soon” and that, in the meantime, we can reserve ours. It also summarizes the promise of privacy with a simple explanation: the username will serve to keep the number hidden from people who do not yet know it. This nuance is relevant so as not to confuse reservation with complete availability. What we have in front of us, for now, is a way to set aside an identifier before general deployment. By clicking on Create usernamethe first thing I did was try my own name. It is a quite natural reaction when a platform opens the pool of identifiers: before getting complicated with numbers, hyphens or combinations, we try to stay with the cleanest form possible. In my case, I wrote Javier and waited for WhatsApp validation. The response was not exactly what I expected. The message was quite specific: “This username is only available on WhatsApp Business.” That is, it did not seem like a normal case of a busy identifier, but rather an availability conditional on the type of account. In practice, this introduces an interesting nuance for those who try to reserve very simple names, especially proper names, because some, apparently, can be left out of a personal account even if they appear associated with another channel. In my case it didn’t make sense to jump to WhatsApp Business. Then I tried another logical option: my last name. It was a reasonable alternative, because it was still easy to remember and fit well with the idea of ​​sharing a personal identifier without resorting to a very long combination. This time WhatsApp did show a much more conventional notice: “Username is not available“There the problem was no longer the type of account, but pure and simple availability, something to be expected in a function that comes to a service with a huge user base. At that point it was time to decide whether to continue trying combinations or choose a reasonable option and continue with the process. I opted for the second. The name I ended up saving was not the cleanest nor the one I would have chosen in an ideal world, but it did what I needed: to clearly identify myself and serve as contact information without exposing my phone number. After accepting the identifier, WhatsApp displayed the message you expected to see: “Username reserved.” The reservation does not end entirely on that screen, because WhatsApp also allows you to adjust who will be able to contact us through the username. In the section Contact me by username I found two options, and the one that was marked by default was All. That is, if I left the configuration as is, anyone who knew my identifier could use it to initiate that first contact. For a function that is presented precisely as a privacy layer, I think that setting deserves review before closing the process. The other option available was People who know my password. When selected, WhatsApp generates a key that works as a second filter for that first contact by username. The idea is simple: it is not enough for someone to know our identifier, they would also have to know that key to be able to start the conversation that way. Here is an important detail that should not be overlooked. In my experience, it is not enough to enter People who know my password and see the password generated by WhatsApp. If we then go back or simply close the application, the setting is not applied and the configuration remains at All. For that additional filter to really work you have to click on Save key. Only then is the key registered and can be consulted later from the same section. That said, we must keep in mind that we are talking about a gradual deployment. If you enter WhatsApp, follow the same route and it still does not appear User nameit doesn’t mean that you are doing something wrong or that your account has any problem. In my case, the option was not available when I heard the news and appeared a few hours later. It is best to keep the application updated on iOS or Android and check again later, because WhatsApp will gradually activate the reservation. It is … Read more

Apple has a plan for its memory problem. The only problem is that it goes through a company on the US blacklist, according to FT

by

The perfect storm hits the memory market and shakes consumer electronics like we have rarely seen. This stretch of the year has become a bad time to update your computerbuy a console or even expand the RAM of a gaming desktop with a new module. The effects They also reach storage units and other components that until not so long ago seemed more or less predictable. Looking back, that problem with graphics cards during the rise of cryptocurrency mining It begins to seem, for many users, almost small next to what we are seeing now. For months, some large manufacturers have tried to buy time with a tool that the user does not see: inventory. Lenovo is a good example. According to statements by its financial director, Winston Cheng, collected by Bloomberg TV and later cited by various mediathe company even had stocks of memory and other critical components around 50% higher than usual to cushion the blow of shortages and price increases. This type of mattress helps to resist better than others, but it also has a limit when the market continues to tighten. Memory has become a problem for Apple, prices and geopolitics And that’s where Apple comes in. We are not talking about a small company trapped by a specific increase in costsbut one of the companies with the most negotiating power in the entire technology industry. Its supply chain has been operating with extraordinary precision for years, supported by huge agreements, global suppliers and a purchasing power that few can match. Precisely for this reason it is so significant that, according to Financial TimesApple would also be looking new ways to relieve memory pressure. The path that has come to light is especially delicate. According to the British business newspaper, Apple is pressuring the Trump Administration to obtain authorization, or at least a favorable signal, that allows it to buy memory chips from CXMT, a Chinese manufacturer singled out by the Pentagon for his alleged links with the People’s Liberation Army. The media adds that the company approached the Department of Commerce more than a month ago and has also sought support in other parts of Washington. The goal would be to alleviate the financial pressure caused by the rising cost of memory. If you’ve been following Apple for a while, you probably already know: these types of moves are almost never made public. The company does not usually explain its internal purchasing operations, much less its conversations with suppliers or administrations. Financial Times attributes the information to six people familiar with the mattera relevant basis to take it seriously, but we are not facing official confirmation from Apple, the White House or the Department of Commerce. To understand the dimension of the movement, CXMT must be well located. We are not talking about a brand of consumer RAM that the user chooses in a store, but about ChangXin Memory Technologiesa Chinese DRAM manufacturer founded in 2016. The company presents itself as a supplier of chips for mobile phones, PCs, tablets, servers and other equipment, memory that can then end up integrated into finished products. In the case of Apple, therefore, the debate is not about a visible brand, but about who supplies a particularly sensitive internal part. The search for alternatives does not come out of nowhere. It’s no secret that the memory industry is highly concentrated on Micron, Samsung and SK Hynix, the DRAM suppliers that Apple relies on for its devices. When the market is balanced, that dependence can be managed with contracts, volume and planning. When prices rise sharply, however, each additional supplier counts. CXMT appears there as a possible way to add capacity. The memory industry is highly concentrated in Micron, Samsung and SK Hynix. As we have seen, what is behind it is not just an isolated increase in prices, but a change of priorities. The AI ​​craze has put advanced memory at the center of the data center business, especially HBM, needed to power high-performance servers and accelerators. That demand has contributed to a prolonged shortage of traditional memory for consumer electronics. That is why the problem is felt in very different products: not because they all use the same memory, but because they compete, directly or indirectly, for a limited industrial capacity. At Apple, that pressure has ended up reaching the showcase. The company raised the prices of MacBooks and iPads by around 20% and attributed the movement to some “unsustainable” memory prices. The same medium maintains that the decision had an immediate stock market impact: $263 billion less in capitalization, Apple’s second largest daily drop. It is advisable to read these figures together, because they tell something broader than a specific increase: when memory triggers, even a company used to protecting its margins begins to transfer tension to the final product. The expression “blacklist” helps to understand the seriousness of the matter, but it can lead to a conclusion that is too quick. CXMT is on the Pentagon’s 1260H list for its alleged links with the People’s Liberation Army, a very sensitive label in the midst of the technological rivalry between the US and China. However, according to the Financial Times, that designation does not automatically prevent Apple from purchasing chips from CXMT or YMTC. The issue is what would happen if the US hardens its position later. The British economic newspaper says that the Department of Commerce had already included CXMT in a package of Chinese companies candidates to enter the Entity List, a much more restrictive trade listbut that the White House asked to wait for negotiations with Beijing. That background explains why the company would want a political signal before moving. It is not enough for a door to be open today if tomorrow it can be closed with Apple inside. John Moolenaar, Republican chairman of the House China committee, told the same newspaper that partnering with a Chinese military company would be “a serious mistake.” He also argued that helping the “Chinese … Read more

If you take these drugs, heat may be more dangerous than you think

by

We all know that, when it is very hot, we should drink a lot of water, avoid going outside during the hours of the sun and cool rooms properly. We also know that the copious meals They are not a good idea and may not be the best occasions to eat spicy food. But what we are not always warned about is that there are drugs that increase the risk of getting sick due to heat, so we must take extreme precautions if we take them. It is not about leaving them, but about being aware of the risks that increase to take the necessary measures. A very long list. The list of drugs that increase the risk of heat-related illnesses it’s very long. Some examples are certain hypertensives, beta-blockers, antiarrhythmics or non-steroidal anti-inflammatory drugs (NSAIDs). It can also occur with opioids, benzodiazepines, antidepressants, antiepileptics, antidiabetics, laxatives, anticoagulants or antihistamines. Does this mean that all these groups of drugs quickly increase the risk of heat stroke? Not necessarily. To begin with, they are not all medications in each group and, furthermore, they do not always affect health for the same reasons. The mechanisms. The main mechanism by which these risks increase is dehydration. For example, some antihypertensive drugs are diuretics. This means that they increase urination, making it easier for dehydration to occur; which, in itself, is more common in a heat wave situation. Symptoms related to impaired kidney function may also occur. When we become dehydrated, the amount of water in our blood decreases, so kidney function can be affected. Therefore, care should be taken with drugs that already affect hydration, as they can increase the risk of kidney failure. On the other hand, there are drugs that affect thermoregulation. If the body is not able to regulate temperature, it is easier to suffer heat stroke. Others affect alertness, so those who consume them may not notice the symptoms of heat stroke. Happens with some benzodiazepines. And something similar happens with drugs that alter the perception of thirst. Finally, there are medications that cause hyperthermia, so that the body temperature rises too high. Sometimes it is bidirectional. Some of these mechanisms can cause the medications themselves to cause more side effects. For example, some NSAID drugs are eliminated through urine, with prior intervention of the kidney, but if it does not function properly due to dehydration, they accumulate, potentially causing toxicity. Furthermore, their way of reducing pain is by inhibiting the synthesis of prostaglandins, which are necessary for renal perfusion, so, with a kidney that does not already function very well, they can be harmful. It is precisely for this reason that, in situations of heat waves extreme, Doctors are advised not to prescribe certain NSAIDs. More cases of increased toxicity. In general, heat can increase the toxicity of some drugs in several ways. For example, dehydration can alter the concentrations of certain drugs in the blood. The difference is usually minimal. However, there are medications, such as lithium, in which the difference in concentration between the therapeutic effect and toxicity is minimal. That is why care must be taken. You should also be careful with cutaneous medications, such as patches, or subcutaneous medications, such as insulin, since if it is very hot they may be absorbed more quickly. People at higher risk. All of this does not affect all people equally. Generally, the risk is greater for older people, patients who live in isolation or with poorly air-conditioned housing and, especially, people who take several medications at the same time. Hydration is essential if you are taking certain medications What should we do? As patients, we must mainly ensure that drugs are stored at the temperature indicated on the package insert. Beyond that, it is usually the doctor who has to pay attention to each patient’s history and determine whether, in a given climatic situation, there may be risks with the drugs taken. In any case, if we have doubts, we can always read the leaflet and/or consult our family doctor about the medications we take. It is important to emphasize that these types of situations are usually extreme. It must be very hot and the person must be vulnerable for some reason. Furthermore, many times these are situations that can be prevented. If the problem is due to the risk of dehydration, the patient is instructed to drink much more water. The same if the problem is that the perception of thirst decreases. Each case is different, so it is important to study them individually, taking into account that they are extreme situations, but that they must be considered if necessary.

New vivo X Fold6, features, price and technical sheet

by

For years we have seen how vivo built, generation after generation, an increasingly ambitious family of folding products. First came the XFoldthen new iterations, improvements in cameras, more refined screens and proposals that looked directly at the highest range. But there was one detail that, from Spain, always left the same feeling: those cell phones passed before our eyes without officially landing here. Now that dynamic changes with the vivo X Fold6a foldable that comes with a very ambitious technical sheet and opens an unprecedented stage for the brand in the country. The X Fold6 arrives with a technical sheet that makes it clear where Vivo wants to place it: in the high range of this format. Everything points to a device designed for photography, work and content consumption, not just to show off its format.

According to vivo, the ZEISS main camera works with a Samsung HPB sensor and five very low reflection lens elements, while the 50 MP ZEISS APO telephoto camera adds a 3x periscopic structureCIPA 4.5 stabilization, ZEISS hyperzoom up to 100x and telemacro up to 20x. The third piece is a 50 MP ZEISS ultra wide angle, designed for wide scenes. Added to this is the ZEISS T coating and the vivo BlueImage V3+ chip, which should help with clarity, stability and efficiency of photo processing, especially in complex lighting scenes. The most unique piece of the system is the ZEISS Vivo 200mm Gen 2 Equivalent Telephoto Extender, a 2.35x optical accessory designed to take the foldable camera further for distant scenes, concerts, live events or travel. vivo speaks 96 mm in length and 153 g in weight, with a Keplerian optical structure of 2 groups and 15 high transmittance glass elements. The press release does not indicate that it is included in the box nor does it yet detail how it will be sold in Europe along with the X Fold6, so that point is pending for the European launch. For reference, vivo now sells the X300 Pro Telephoto Extender Kit in Europe for 349 eurosreduced from 399 euros, and also offers it associated with photographic kits of the X300 family. Autonomy is another point where I want to distance myself. The X Fold6 incorporates a battery 7,000 mAh BlueVolt In the versions presented, a particularly striking figure in a foldable, where the internal space is usually more conditioned by the hinge and the double screen. This is supported by a third-generation semi-solid battery and fifth-generation silicon anode technology, designed to increase energy density. Charging is completed with 80W FlashCharge wired fast charging, 40W wireless fast charging, and reverse charging to power other devices. In performance, vivo does not resort to a secondary platform, but to the Dimension 9500 improved, a version worked together with MediaTek for large screens, multitasking and artificial intelligence on the device itself. We are talking about MediaTek’s most powerful SoC and a direct rival to Qualcomm in the premium range, although not the most powerful Android processor in absolute terms, because that place corresponds to the Snapdragon 8 Elite Gen 5. It is pure high-end, the same league as mobiles like the Oppo Find X9 Pro and the vivo X300 Pro. On that basis, Vivo promises 111% more peak performance on the NPU and 56% less peak consumption on that unit compared to the previous generation. The other big half of the experience is on the screens. The vivo X Fold6 incorporates a 8.02 inch inner and a 6.51-inch exterior, both 120 Hz LTPO, a refresh rate that should help make scrolling, animations, and switching between apps feel more fluid. The key, however, is how I try to take advantage of that large canvas with Atomic Workbench. According to the company, the ‘series’ mode allows you to use up to five applications in the foreground and four in the background, while the ‘parallel’ mode places up to four active apps side by side to compare information and work without constantly switching applications. vivo also tries to reinforce the idea of ​​premium folding from design and resistance. The X Fold6 will be available in China in blue, white and black: the blue model uses glass with a frosted finish inspired by the large blue holes of the … Read more

Germany and France need to imitate Spain to survive the heat

by

Melting roads, bursting train tracks and firefighters watering bridges. While in Spain we deal with the heat by lowering the blinds, in Europe we are looking for solutions to try to survive a heat wave that has blown up the most basic mobility infrastructures. “You should look at Japan”. “You should look at how rail transport works in Japan. There it also reaches 40 degrees in summer and the trains are not constantly cancelled” or “it happened 20 years ago, the air conditioning has failed. (…) the problem has existed for a long time and nothing is done.” There are two comments that reported in one of the local media in Bavaria (Germany). In the text, one of the reporters explains that “the passengers were completely sweaty and accepted the situation with resignation” when it was reported that the regional train in which they were traveling had broken down its air conditioning. With 35 degrees outside and more than 40 degrees inside, the problem was obvious. So evident that Marco Kragulji, spokesman for the German passenger association “Pro Bahn”pointed out that, quite simply, “Germany has problems with its trains when the heat comes.” Click on the image to go to the original tweet Germany, Belgium… German trains with broken air conditioning have been just one of the problems encountered by rail traffic in a burning central Europe. And in the country too Tram tracks have been broken in the city of Essen because of the heat. It is by no means the only case. In Brussels the tram tracks have also jumpedtearing up the asphalt and completely stopping traffic. The causes are simple: train tracks are designed to withstand temperatures typical of countries that used to be colder. Heat expands the materials and ends up splitting them.destroying the infrastructure. Click on the image to go to the original tweet “We recommend that you do not take the train”. In addition to broken tracks, SNCF (the French Renfe) has recommended that “vulnerable users” don’t take the train. And the problems with the air conditioning are constant and have even been the main reason why Dozens of trains were suspended last week. The problem is that the heat is being so extreme that it is putting the trains that have been in operation for more than 20 years to the test. Those trains were designed in a context that, except for the heat wave of 2003, does not exist today. And now the Spanish trains are given as an example, much better armed to withstand extreme temperatures. looking south. In the German media they use the Spanish and Italian infrastructure as an example. They claim that Deutsche Bahn (in this case, the German Renfe) designed the rails for the train to withstand temperatures that are now considered too low. And the problem, they point out in this medium specialized in engineeringit is not the ambient temperature, it is that the tracks, due to the concentrated heat and the passage of the trains, reach much higher temperatures that, now, break the tracks. Generalists focus on the fact that Spanish and Italian roads use colors that reflect the sun to reduce the temperature. But also They praise the air conditioning systems of Spanish trains that are more powerful and with more recurring departures within the cars. Both France and Germany point out, however, that the latest generation trains that are arriving on their tracks already use powerful air conditioning systems to face these new situations. And they are even adding batteries to ensure that the air conditioning remains active in case of a breakdown. Photo | Linus Follert and windy In Xataka | Some roads are literally melting.

Millions of men wake up every morning with an erection. This is excellent news for them.

by

There is a deep-rooted popular belief that associates the presence of morning erections exclusively to testosterone levels and the “virility” that man has. But recently it is being seen that this is something that can be an indicator of having good cardiovascular health, although logically not having them does not categorically mean that there is a disease in the heart or arteries. Its foundation. Here the scientific literature has a very important position, since, although there is a real basis to point out that the absence of these erections is an important symptom, it does not function as a ‘yes or no’, but is a continuous and complex marker. In this way, if we analyze the evidence from the most powerful population studies of recent decades, we discover that morning erections speak much less about our hormones and much more about our arteries. A thermometer of cardiovascular health. To understand why an erection matters at a systemic level, we must remember that we are dealing with a fundamentally vascular phenomenon. The arteries of the penis in this case are much narrower than the coronary arteries, and that is why, if we have a process of atherosclerosis or endothelial dysfunction that is beginning in the body, the smaller arteries will be the first to fail. This is why erectile dysfunction is a very important predictor for cardiologists and urologists to know what the inside of the arteries may be like without having to do any extra tests. Risk in escalation. A landmark study published in PLOS Medicine in 2013 continued to more than 95,000 men and showed that cardiovascular risk is increasing. In this way, it was seen that men with severe erectile dysfunction had almost double the risk of general mortality compared to those who did not suffer from it. This adds to a second study published in Circulation with almost 93,000 men which confirmed that erectile dysfunction increases the risk of total cardiovascular events by 44% and the risk of acute myocardial infarction by 62%. Testosterone. This is where popular culture collides with the data provided by scientific evidence. It is true that testosterone reaches its maximum peak in the morning and it is logical to think that this enhances the morning erections that men have, but a 2019 observational study carried out on 761 men showed that those who maintained their nocturnal erections had, on average, slightly higher total testosterone and lower libido. But testosterone does not explain the risk of suffering from serious disease in our arteries. Here the European Male Aging Study followed about 1,660 men for more than 12 years and analyzed different specific symptoms: erectile dysfunction, low libido and loss of morning erections. And here they saw that having poor erections in the morning increased the risk of mortality by 28%. It’s not testosterone. The key to this study is that, when adjusting the results based on the patients’ testosterone levels, the risk of mortality remained exactly the same. This means that it does not matter whether you have more or less testosterone, because what is truly important here is to have ‘clean’ arteries that allow blood to be carried to the penis without any type of obstacle. There is no need to obsess. We must not fall into the trap of stating that the absence of morning erections is the same as having a major underlying disease. What we must keep in mind is that we are faced with one more risk factor or symptom that is added to many others in a complex puzzle that must occur for a specific disease to occur, and that is why this is something that is left in the hands of medical specialists to determine what may be happening inside the arteries.

A cement company stopped sending its personnel to inspect dangerous areas. Your new inspector is a robot dog

by

Even though the conversation revolves around humanoid robotics Lately, this sector has had much more traction in the industry for decades, driving a good part of the current processes and assembly lines. In this regard, a Swiss cement plant has wanted to take advantage of robotics in a somewhat peculiar way: it has been using a quadruped robot to monitor your facilities every night. Below these lines we tell you all the details. The problem that had to be solved. Vigier Ciment has been producing cement in the hills of the Swiss Jura, south of Biel, for a century and a half, generating approximately a fifth of all cement in the country. Its plant houses more than 1,000 machines spread across several buildings and floors, connected by metal stairs of up to 16 sections, areas with temperatures that reach 50 degrees, constant dust and the occasional presence of ammonia near the unloading docks. The maintenance of all this fell to operators who toured the facilities on foot filling out paper records. Over time, continued exposure to these conditions generates what the plant workers themselves call “operational blindness.” You stop seeing what is in front of you because you have already seen it too many times, according to collect Techeblog. The guard dog. Just like account The medium, in November 2024 the Swiss robotics company ANYbotics began talks with Vigier Ciment to deploy its ANYmal quadruped robot at the plant. The robot arrived on January 6, 2025 and before the end of the first month it was already carrying out night patrols completely autonomously. ANYmal is similar in size to a large dog and weighs more than 50 kilos. It does not need human supervision, and its managers say it climbs stairs, avoids obstacles, navigates narrow hallways and accesses areas that previously required considerable effort on the part of staff. What exactly does it do in every round. Every night, even on weekends, ANYmal goes through more than 450 inspection points predefined elements distributed in three mills and six levels. To do this, it has several detection systems, including a visual camera that identifies cracks, oil leaks or corrosion; a thermal camera that measures the temperature of critical components such as bearings, motors and gears; a gas sensor that monitors ammonia levels; and an acoustic camera capable of locating compressed air leaks or filter failures at distances of up to 50 meters. According to point In the middle, all that information is automatically dumped into a software platform called Data Navigator, which analyzes the data collected overnight, compares it to the facility’s history, and generates a daily report for the maintenance team. What he has found along the way. In sixteen months of operation, ANYmal has already completed more than 33,000 inspections without recording any technical failures. According to ANYbotics, the most relevant findings have had a direct impact on plant operations. The middle share In addition, the robot detected a crack in the base of a shredder the size of a large kitchen table. The oil had been leaking for some time and no one had reported it on the usual rounds. The repair was completed the next day. Had it collapsed, the plant would have lost more than a week of production, with estimated losses of more than $630,000, according to the company’s own figures. In another case, thermal monitoring detected a bearing reaching 140 degrees Celsius, allowing a $30,000 eight-hour repair to be scheduled rather than facing a much more costly emergency failure. The robot also detected levels of ammonia exposure at unloading docks that had not been measured until then, and located air leaks in filtration systems installed 50 meters high. Industrial maintenance. The plant’s traditional fixed sensors only covered about 200 elements, mainly on the clinker side (the main component of cement). The robot expands that coverage substantially and accesses areas that static sensors cannot reach. At the same time, it removes operators from the most dangerous environments without reducing the frequency or quality of inspections.
