Someone has said that melatonin damages the heart. The reality, according to science, is that we can be calm

by

Melatonin is a hormone that now is on many people’s lips being a key element in the regulation of our biological clock, and above all being well known for its relationships with sleep induction. It is precisely for this last reason that in recent years people have been supplementing with melatonin pills to be able to sleep better or regulate their sleep schedules more, but now the alarms have gone off about the possible side effects it may have. The alarm voice. There are many benefits that melatonin has with its continued use as a supplement beyond those related to sleep, such as anti aging thanks to its antioxidant capabilities. But beyond the benefits, a study has raised the alarm: it can cause heart failure. However, there is much to qualify in this statement. Obviously, something like this can generate great unrest in society, precisely because it is a widely used supplement in different countries because it can be purchased without any type of medical prescription (except for the highest doses). And this attraction has been used to create pills, gummies or even infusions that have melatonin inside. But the reality is that nothing we ingest can be harmless to our body, especially if very specific safety guidelines are not followed. Although in the case of melatonin everything indicated that it was completely safe and that everything behind it was something positive. Until now. What the study says. The focus of the controversy centers on a preliminary study (and this is important) that is going to be presented at the American Heart Association Scientific Sessions 2025. This work analyzed the medical records of more than 130,000 adults with insomnia, comparing 65,414 people who had used melatonin for a year with another group who had not used it. The results of this study they pointed in this case because users who used melatonin chronically were twice as likely to be diagnosed with heart failure. But they went further by showing that there was a 3.5 times greater risk of hospitalization for heart failure. But saying ‘double’, the truth is that it does not provide much information (beyond fear), but what is important here would be to talk about the absolute increase in risk, as the Secretary of State for Health points out in his X account. Tranquillity. But the reality in this case is that there is no need to sound the alarm immediately because of the ‘fault’ of a study that has not yet been reviewed (since it is not even published in a journal). Right now there is a large amount of scientific evidence that proves how safe melatonin isand a single study does not put in check all the scientific literature behind it, although it does open a door to be able to investigate in a more in-depth way. melatonin side effects. For example, in 2022 a systematic review was published on high doses of melatonin in adults found minor adverse events such as drowsiness, headache or dizziness, but no increase in serious adverse events. The same thing happened with the StatPearls article of 2024 which indicated there was no evidence of toxic effects. Specifically in chronic use we have a 2023 study by Givler which confirms that the administration of between 5-6 mg of melatonin per day does not generate serious long-term risks. Although logically it is important to use it above all as an ‘help’ to have more adequate sleep hygiene with the aim of not depending on exogenous melatonin to be able to sleep. And it is necessary to carry out studies that are appropriate to look for this correlation. The study that has highlighted melatonin is not the most appropriate as it is observational and not a randomized clinical trial. This means that it has not been possible to verify exactly whether these differences are due to chance and, above all, there has been no control over the patient groups, since it has been done with their clinical histories. The correct thing to do in these situations is to propose a study with two groups: one where patients take melatonin and another where they do not. But until we reach this point, it is important to calculate the number of patients needed, how they are selected and the baseline characteristics they must have so that there are interchangeable patients in both groups and many other factors. Everything necessary so that the conclusion of the study has great external validity for the entire population. Investigation remains. Logically, any type of supplement, and especially if it is hormonal, can lead to different side effects. The issue in this case is that research is needed to look for side effects and ask ourselves if it is necessary for doctors to start prescribing it in all doses. And, as we have said before, a prescription is only needed for the highest doses, but the lowest doses can even be found in a supermarket. Although whenever you have doubts about the safety of the medication, the important thing is always to consult with your primary care doctor so that the dose can be adjusted based on the particular history of each patient.

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.

The language. The translation reaches the heart of their chats

by

We have all lived the frustration of not understanding with someone for a simple language. It can be on a trip, in a working group with colleagues from other countries or even in a conversation with family members abroad. In that field where words fail, WhatsApp has decided to take another step: Integrate translation directly in your chats to reduce that friction. With more than 3,000 million users Distributed by more than 180 countries, WhatsApp connects to very diverse communities. The new translation function is presented as a real communication response with less barriers. How it works. The process to translate is direct and does not require leaving the chat. Simply hold a message and choose the “Translate” option. The application will show the text in the selected language and save the downloaded packages to use them in the future. The function is available in individual conversations, groups and also in the updates of the channels, which expands its reach beyond private exchanges. Languages ​​and deployment. The new function begins to gradually arrive at Android and iPhone users. In the case of Android, the start is limited to six languages: English, Spanish, Hindi, Portuguese, Russian and Arab. In iOS, on the other hand, the fan is broader: more than 19 languages ​​from the beginning, supported by Apple’s infrastructure. Android self -translation. In addition to the manual option, Android users will have an additional function: automatically translate all incoming messages of a concrete conversation. Once activated, any text received in another language will be displayed in the language chosen by default. It is an option designed for those who maintain continuous exchanges in another language, avoiding having to translate a message by message. Privacy on the device. The deployment of the function is accompanied by a key nuance: translation does not abandon your mobile. According to WhatsApp, the entire process occurs in local and the company has no visibility on the texts that become another language. The measure responds to the need to preserve privacy in a service where users share sensitive information, respecting the security framework provided by end -to -end encryption. What does not translate. The new tool is not universal: there are contents that are left out. WhatsApp details that locations, documents, contacts, stickers or gif cannot be translated. In addition, as we have said, to use the function it is necessary to previously download the language packages and have sufficient storage space. Integrated translation is not limited to travel scenarios. It can be useful for merchants who serve tourists and need to understand orders instantly. In the workplace, teams distributed in several countries can maintain the rhythm of their conversations without depending on external translators. Even in the daily life of multicultural neighborhoods, the function adds fluidity. Until now, the alternative was going to copy the message and take it to an external translator, or use the translation functions of the mobile system. Both options solve the problem, but add intermediate steps that break the immediacy of the chat. WhatsApp’s bet is that everything happens in the same place where the conversation has already elapsed. Images | Mariia Shalabaieva | WhatsApp In Xataka | Send files among all my devices was a roll.

China is no longer made up of moving away from Nvidia. His next step is the heart of the AI ​​with a system that breaks molds

by

In 2017, the Paper “Attention is all you need”Google changed the technical basis of language generation: the Transformers They allowed to process long sequences in parallel and climb models to sizes that were previously unfeasible. That climbing route has driven architectures such as GPT and Bert and has converted self -how The central piece of generative AI Contemporary. But this new approach was accompanied by growing costs in memory and energy when the context lengthens, a limitation that has motivated research to develop alternatives. Spikingbrain-1.0 aims to break molds. Of the “attention is all you need” to the brain: the new commitment to break limits in the A team from the Chinese Academy of Sciences Automation Institute He has just presented Spikingbrain-1.0. We are talking about a family of spiky models aimed at reducing data and computation necessary for tasks with very long contexts. The experts propose two approaches: Spikingbrain-7B, of linear architecture focused on efficiency, and spikingbrain-76b, which combines linear attention with Mixture of Experts (MOE) mechanisms of greater capacity. The authors detail that much of the development and the tests were carried out in clusters of GPU Metax C550, with libraries and operators specifically designed for that platform. This makes the project not only a promising advance at the software level, but also a demonstration of own hardware capabilities. An especially relevant aspect if China’s effort is taken into account for reducing his dependence on Nvidia, A strategy that we already saw reflected with Depseek 3.1. Spikingbrain-1.0 is directly inspired by how our brain works. Instead of having neurons that are always “burning” by calculating numbers, uses spiky neurons: units that accumulate signals until they exceed a threshold and trigger a peak (spike). Between peak and peak they do nothing, which saves operations and, in theory, energy. The key is that not only does it matter how many peaks there are, but when they occur: the exact moment and the order of these peaks carry information, as in the brain. In order for this design to work with the current ecosystem, the team developed methods that convert traditional self -acting blocks into linear versions, easier to integrate into its spiky system, and created a kind of “virtual time” that simulates temporal processes without stopping the yield in GPU. In addition, the Spikingbrain-76B version includes Mixture of Experts (MOE), a system that “awakens” only to certain submodos when we are needed, which we have also seen in GPT-4O and GPT-5. The authors suggest applications where the context length is decisive: analysis of large legal files, complete medical records, DNA sequencing and massive experimental data sets in high energy physics, among others. That lace appears reasoned in the document: if the architecture maintains efficiency in contexts of millions of tokens, would reduce costs and open possibilities in domains today limited by access to very expensive computer infrastructure. But validation in real environments is pending outside the laboratory. The team The code of 7,000 million parameters has released in Github next to a detailed technical report. It also offers a web interface similar to chatgpt to interact with the modelwhich according to the authors are deployed entirely in national hardware. Access, however, is limited to Chinesewhich complicates its use outside that ecosystem. The proposal is ambitious, but its true scope will depend on the community to reproduce the results and make comparisons in homogeneous environments that evaluate precision, latencies and energy consumption in real conditions.

The effect of heat on our heart rate when playing in summer

by

It is the summer stamp: go running or riding by bike and, a few minutes later, the pulsometer is triggered to figures that do not correspond to the effort. And it’s not a strange thing to see. It is the body that is trying to respond to a series of stimuli such as heat and exercise, and understanding its physiology is important for Do not turn sports into a health risk. Exercising in summer is a great challenge. In this situation the body is forced to respond to two specific demands. On the one hand, Muscles in action need a lot of energy in the form of ATP To contract. However, this is an inefficient process, since It only takes advantage of between 20 and 25% of the ‘produced’ energy releasing the remaining 80% in the form of heat. This energy in the case of not dissipating it correctly can raise internal body temperature by 1 ºC every 5-10 minutes. How to avoid it. On the other hand, to avoid precisely that lethal overheating, the body thermoregulatory center located in the hypothalamus, Activate powerful cooling mechanisms. One of them is to pump huge volumes of hot blood from the body nucleus to the skin, causing it to be red by that large amount of blood that is going through the surface of the body. This double duty is the fundamental reason why the pulse shoots and becomes the most sensitive and critical indicator of the stress to which the body is subjected The organism has to compensate. These two situations cannot be carried out in parallel, but A balance must be achieved. And it is that when the system is taken to the limit by the intensity of the exercise and the severity of heat, something has to yield. Or blood flow is reduced to the muscles, limiting the ability to maintain rhythm, or the flow to the skin is committed, limiting heat dissipation and increasing body temperature to dangerous limits. Understanding this internal negotiation is key to understand why training in summer is much more than a simple matter of willpower. The skin becomes a giant radiator. The first and most powerful response of the body to the increase in skin temperature and body nucleus It is body vasodilation. Controlled by the ‘thermostat’ of the body, the preoptic area of ​​the anterior hypothalamus, this mechanism causes the blood vessels close to the skin to widen and make it become a refrigerator. Under resting conditions and neutral temperature, the cutaneous blood flow is just about 300 ml/min. However, during an intense exercise in a hot environment, this flow It can shoot until reaching 7 or 8 liters per minute. Something that also represents around 50 and 70% of all cardiac output. And this is a simple deviation of resources with the objective of dissipating heat by convection and radiation. Although it is not free. It has an important cardiovascular cost. The heart accelerates to compensate. The fact of opening the ‘pipes’ that lead the blood to the skin causes the heart to have to activate an important compensation mechanism so that the organs remain perfused. We talk about heart rate, which will be increased. The objective is to maintain cardiac output, so that blood pressure is stabilized despite the low peripheral resistance due to vasodilation. A crucial aspect of this process is speed. The initial increase in heart rate is an incredibly fast neural reflex, triggered by Thermal skin receptors. This response often precedes any significant increase in central body temperature. This shows that the body not only reacts to heat, but anticipates it, preparing the cardiovascular system for the thermoregulatory battle that is coming. The key is in cardiovascular drift. Any athlete who trains with a pulsometer in summer will have noticed a disconcerting phenomenon: even maintaining a constant rhythm, the pulse tends to rise progressively throughout the training. This is something that has been documented and called ‘cardiovascular derives‘, which is defined as the gradual and continuous increase in the heart rate that occurs during a prolonged exercise of constant intensity, accompanied by a decrease in systolic volume (the amount of blood that the heart pumps in each beat). And precisely the heat stimulates the two mechanisms that drive this phenomenon: The increase in skin flow by vasodilation. This causes blood to ‘stagnate’ temporarily on the periphery, which reduces venous return. This means that the heart does not fill so much in each beat, and therefore the amount of blood that will expel will be less. Dehydration Sudoration is essential to cool the complete system, but it entails a loss of body fluids, mainly from the blood plasma. This again reduces that the blood returns to the heart so that the same volume can be pumped. And to compensate the only thing left is to increase the heart rate. The pulse increase per centigrade grade. Once the ‘why’ of this increase in heart rate is known, an athlete is interested in knowing the ‘how much’. And the reality is that studies have established a very useful general rule to know how our body temperature increases when exercising: In dry heat conditions, with environmental temperatures above 24 ° C, the heart rate Increase approximately one beat per minute for each celsius degree of temperature increase. In wet heat conditions, the impact is multiplied. Here the increase in heart rate triggers between 2 and 4 beats per minute for each degree Celsius that increases the ambient temperature. This difference is not trivial. Exercise at 34 ° C in a dry climate (10 ° C above the threshold of 24 ° C) could involve an increase of about 10 beats per minute in the heart rate for the same effort. On the other hand, to those same 34 ° C, but with a high humidity, the increase could be 20 to 40 beats per minute. This additional load on the heart explains why we call as ’embarrassing’ feels much more … Read more

The C929 wants to be the great leap of China in commercial aviation. For now, your heart remains in Western hands

by

For years, the domain of commercial sky has been in the hands of two giants: Airbus and Boeing. China wants to break that hegemony, and is willing to do it with its own name in the cabin. Comacthe China commercial aircraft corporationhe has been trying to make planes capable of competing with global references for years. First was the C919. Now, the bet is redoubled with The C929. This new model, even in a preliminary design phase, represents the most serious ambition of Beijing for placing a long -range plane on the international board. The objective is clear: to deal with heavyweights such as the Airbus A330neohe A350 or the Boeing 787 Dreamliner. And the figures accompany: capacity for about 280 passengers, an estimated autonomy of 12,000 kilometers and a design that, on paper, would allow to cover routes such as Beijing – New York. The internal deployment of C919: a discreet but strategic conquest The C919 has not conquered the global sky, but it has begun to take off within China. Since It was officially presented in 2017has gone through years of evidence, certifications and adjustments. SCMP points out thatas of June 2025, about 18 units fly domestic routes, mainly operated by airlines such as China Eastern. It may seem little, but the fact that it works only in China is not necessarily a failure. On the contrary: We talk about one of the largest aviation markets on the planet. And in that context, having its own plane capable of covering regional routes without depending on Western manufacturers is already, in itself, a strategic movement. The real commitment of Comac, however, is the C929. A plane from Width and long scope fuselage which aims to stand up to the most advanced models in the market. The project has won impulse in recent months: Air China signed an agreement To become a launch customer, and a supplier has reported that he hopes to deliver the first fuselage section in 2027. PROMOTIONAL IMAGE OF COMAC C-929 The development of C929 has a peculiar history. In the beginning, it was a joint effort with Russia. The project was then known as CR929, under the baton of a mixed company between Comac and the UAC Russian, called CRAIC (China-Russia Commercial Aircraft International Corporation). However, political tensions, the invasion of Ukraine and international sanctions on Moscow ended up forcing The dissolution of that alliance. Since 2023, Comac has moved on solo, turning C929 into an exclusively Chinese project. Comac has presented this plane highlighting several advanced technologies, including a Optimized aerodynamicsstate -of -the -art engines and integration of smart flight systems. In theory, it is a plane at the height of its western competitors. A C-919 Landing in China But there is a key detail: to fly, the C929 needs much more than Chinese wings. His “technological heart” continues to depend on the West. Safranthe French giant of the aerospace industry, He has signed a Memorandum of Understanding with COMAC to supply the brake system, ice detection, tire pressure sensors and oxygen system. For her part, the American Crane Aerospace will provide sensors for cabin doors. Although these agreements show that Comac is still able to attract international suppliers, they also put an uncomfortable reality on the table: their program remains, to a large extent, Tied to foreign technology. And that, in an uncertain global context, is a latent risk. The Russian precedent that China cannot ignore Russia offers a mirror. The latest Western sanctions cut off the country’s access to key components for its aeronautical industry. The TU-214a half-long reach that could transport between 155 and 210 passengers and fly to about 6,500 kilometers, was severely limited. Many of their critical systems depended on foreign technology. Moscow has worked since then in local substitutions, but possibly at the expense of performance and reliability. China, of course, has proven to be very resilient. He has dodged restrictions in sectors such as semiconductors, and has learned to convert traction obstacles. However, a change in United States commercial policy I could leave them without western engine. “If the US authorities prevent ge supplies the engine, then there will be no CFM engine,” A spokeswoman for Safran warned during the Paris Aeronautical Hall.

This map distributes the “heart” of Europe over the Iberian Peninsula. And reveals the key to the success of the region

by

Maps are useful, fascinating and sometimes almost almost An art form. However, they do not always allow us to understand real dimensions and distances well. Especially when we talk about broad territories. A map published in Urbanity.one (and shared by Madrid projects) With a peculiar approach: its author has taken some of the main cities of Central Europe, the metropolis of the one known as “Blue Banana”and has distributed them on a plane of the Iberian Peninsula respecting The real distances. The result reminds us of two things. The first, the considerable size That has Spain. The second, how close the cities of Central Europe, a crucial factor to understand the history and economic development of the region. As a picture is worth more than a thousand words, at the end of the 1980s the Geographer Roger Brunet decided to invent A visual metaphor to refer to the most populous and urbanized region in Europe. He called her The “Blue Banana”. Maybe it sounds strange, but it makes enough sense when a map is taken. If the cities of the European industrial axis are connected, covering from England to the Netherlands, Belgium, Germany and northern Italy, that is: the drawing of A huge banana Located more or less between Manchester, Munich, Zurich and Rome. How big is that “Banana” imaginary? The first response to mind is obvious: very much, right? In Madrid it projects They have shared However, a map that helps to understand that this abstract axis is actually much smaller than what intuition suggests. At least if we compare it with Spain. The reason is very simple. Its author has selected the metropolis that are distributed by that theoretical axis that structures Europe Central and has arranged them on a map of the Iberian Peninsula respecting the real distances between them. The result It shows that Cambridge would be more or less where Vigo is, Rotterdam would stay up to Valladolid, Bremen in Pamplona, ​​Stuttgart almost where Alicante is and Paris would more or less occupy the place of Badajoz. In the center of the Peninsula, in Madrid, it would be located (kilometer up, kilometer down) Düsseldorf and the Barcelona space would occupy by Linz, an Austrian city. The cast may be striking, but it arrives with pulling Google Maps and its measurement tool for Check the distances. Between London and Paris there are about 340 km in a straight line, just under those that separate Madrid and Granada. If we pull a straight line from Rome to Munich would measure approximately 700 kilometers, a little less than Barcelona to Córdoba. Comparisons are interesting for several reasons. The main one is that they remind us The great size of Spain. The Iberian Peninsula measures just over 583,000 km2 and Spain occupies approximately 505,000taking into account the 12,500 km2 of island surface. That makes our country one of the most extensive of the community club, together with France and Sweden and Germany. A wide disposition of land is both an opportunity and a challenge in aspects as a distribution of the population or provision of services. The other great conclusion left by the map Shared by Madrid projects It is the close thing that are actually the Central European metropolis and their main industrial poles, population centers and strategic axes of political decision -making, a proximity that has influenced the development and integration of Europe.

It will build a repair center in the heart of China

by

As of April 1 ASML will not be able to sell To its Chinese clients its measurement and inspection equipment of integrated circuits. Dutch administration has tightened its controls export to China, aligning with The sanctions approved by the US At the beginning of last December. In practice, these prohibitions force the largest manufacturer of the planet’s lithography equipment to request licenses from the Netherlands government to export a good part of its machines. However, this is not all. At the end of last February several US officials They met with their Dutch and Japanese counterparts With a firm purpose: negotiate what steps can take to drastically limit the participation of ASML and Japanese Tokyo Electron engineers in the maintenance of semiconductor production equipment that are being used by their Chinese customers. China is already the largest Asml market The sanctions that the US governments and the Netherlands are approving are degrading the ASML business in China. It is inevitable if we are in mind that this European company cannot sell its most advanced lithography equipment to its Chinese clients. And neither can some maintenance and after -sales services services provide. The most surprising thing is that despite the current situation the Chinese market is increasingly important for ASML. Despite the current situation, the Chinese market is increasingly important for Asml In 2022 the sales of this company in China amounted to 2.9 billion euros, which represented 13.8% of its annual sales. At that time Taiwan was a more important market for Asml than China. In fact, in 2023 the clients of the island bought lithography equipment for a total value of 8,100 million euros, while its Chinese clients disbursed 7.3 billion euros. And, curiously, in 2024 China was consolidated as the largest market for ASML with total sales of 10.2 billion euros. To understand where this figure comes from, we need to keep in mind something important. As we have seen, ASML cannot sell its most advanced equipment to its Chinese clients, such as the machines of extreme ultraviolet lithography (UVE) or deep ultraviolet (UVP), but at the moment you can deliver the solutions that allow producing chips with mature integration technologies. These are the semiconductors that are mostly used in cars, appliances or electronic devices, among other products, and usually occur in nodes of 28 nm or less advanced. Anyway all these machines need maintenance. And ASML is determined to guarantee it to its Chinese clients beyond the very likely reluctance that US governments and the Netherlands can put. According to SCMP This company will build a repair and reuse of lithography equipment in the heart of China. In Beijing. This decision comes at a time when The tension between the US and China is maximumso, in reality, it is a very clear statement of intentions: ASML will protect your business in China at all costs. We will see what the government’s response led by Donald Trump will be. Image | ASML More information | SCMP In Xataka | Japan wants to recover leadership as a manufacturer of lithography equipment.

Apple Watch technology in headphones. Measuring heart rate is no longer just a clock

by

Apple bought Beats Music and Beats Electronics in 2014 and, although the AirPods are still the most recognizable headphones of the company, the development of Beats has not stopped since then. The Powerbeats pro 2 They are the new beatic headphones and, in addition to respecting the hook format that works so much in the sports market, these are the first headphones under the Apple umbrella that land with A curious function: heart rhythm monitoring. These headphones, at a technical level, arrive with cancellation of active noise, adaptive equalization, space audio, Apple H2 chip and total compatibility with Apple devices (hands -free with Siri, network search, link with a single touch, etc.) They promise an autonomy of up to 10 hours Of continuous reproduction, they work with Qi wireless loaders and are resistant to both sweat and water. What is expected of beats that are launched at a price of 299.95 euros. What does a cardiac monitoring sensor paint in headphones Made the presentations, the clear doubt comes in its key specification. These powerbeats are capable of Measure our frequency in real time. They become the first Beats product to incorporate this monitoring. But how do they work in headphones? According to Beats, a lot of development has been invested to design and locate these control sensors. In this case, They are located right next to the padand make green light more than 100 times per second. The company details that the years of research in heart rate control of Apple Watch have been used to continue this development in the headphones, reducing technical architecture to 1/16 of its original size to integrate it into a headset, without compromising comfort or precision.

The quoted is mandatory because, to date, Apple Watch heart rate measurement is one of the most reliable proposals. If Beats has managed to take this technology to its headphones, at least on paper, They should lead this land. Beyond this particular case, these headphones They will be an excellent thermometer.
