What happened so that in the long term we lost the race

by

At the moment USA and China monopolize all the prominence in the field of Quantum computers. His struggle for world supremacy has many ramifications, and, precisely, Quantum technologies They embody one of them. Both countries have reached Quantum supremacyand, on paper, they are also the most developed in the still premature field of quantum telecommunications. However, this story did not start with them. He was born in Europe. And he did it at a time when quantum computers had already been outlined from a theoretical point of view, but seemed unfeasible. Everything changed in 1995. That year the Spanish physicist Ignacio Cirac and the Austrian physical veteran Peter Zoller They published the article which is unanimously considered the cornerstone that supports the birth of quantum computing as we currently contemplate it. Without their work in all likelihood, current quantum computers would not exist. Or, at least, they would have arrived later. It all started with Cirac and Zoller The roads of these two researchers crossed in the early 90s. Ignacio Cirac had finished the physics career at the Complutense University of Madrid in 1988 and decided to travel to the US to complete his doctorate with the prestigious physicist Peter Zoller. His collaboration was very fruitful From the first moment, so together they began working in such promising fields, and, at the same time, as complex, as quantum cryptography or teleport. Other researchers had proposed before them the possibility of building a quantum computer, but nobody knew how to do it. At that time no physique knew what the right strategy was to put a quantum computer. Zoller and Cirac did know In 1994 Cirac and Zoller attended a conference in which other researchers explained the enormous potential they had from a strictly theoretical point of view quantum computers. However, at that time No physique knew what the right strategy was To set up one of these machines. Zoller and Cirac surveys inspiration shortly after witnessing that conference, and realized that they had found a way to build a machine capable of carrying out calculations with quantum bits or cubits. His scientific article was published in Physical Review Letters on May 15, 1995. They titled ‘Quantum Computations with Cold Trapped Ins’ (Quantum computing with cold ions), and, despite their exoticism, many other physicists immediately realized that what Cirac and Zoller proposed had a huge potential. If we intend to set a date to identify the germ that gave rise to the birth of quantum computers it seems reasonable to accept what should be the day in which the text of these two European physicists saw the light. In any case, one of his greatest successes was his ability to gather the world of abstract theories of quantum computing in which other physicists worked before them with atomic physics, molecular physics and optics. In fact, the title of your scientific text already contains one of the types of cubits most advanced currently available: Quantum bits of ion traps. Honeywell or Ionq are two of the companies that have collected their witness and several decades later they have managed to put this type of quantum machines ready. The recognition of the scientific community soon arrived. Zoller and Cirac were consolidated as two central figures in the formation of international research groups, and, above all, both were actively involved in the constitution of European Quantum Technologies Development Programs. Zoller collaborates closely since the beginning of the 2000 with the Institute for Inns Information and Quantum Optics (Austria). And Cirac has directed since 2001 the theoretical division of the Max Planck Institute of Quantum Optics housed in Garching, a peaceful town located a few kilometers from Munich (Germany). Europe has failed to transfer its academic leadership to the industry The thrust of Ignacio Cirac, Peter Zoller and many other scientists with whom they have worked has not been enough to deliver industrial leadership to Europe in the field of quantum computers. Currently the old continent remains a world power in research thanks to the work that the groups of Quantum Physics of the University of Technology of Delft, in the Netherlands; the Max Planck Institute of Quantum Optics, in Germany; the Federal Polytechnic School of Zurich, in Switzerland; the Center for Quantum Technologies of Paris, in France; the National Center for Quantum Computing, in the United Kingdom; or the Institute of Fotonic Sciences, in Spain, among other academic institutions. Leadership in scientific research does not necessarily guarantee industrial leadership in those applications derived from these technical innovations But it is not enough. Leadership in scientific research does not necessarily guarantee industrial leadership in those applications derived from these technical innovations. This is the big problem that Europe has had. He has not managed to transfer his academic leadership to the industry. During The conversation I held In October 2019 with Juan José García Ripoll, a researcher of the Fundamental Physics Institute of the Higher Council for Scientific Research (CSIC) that develops its research activity within the Quantum Information Group and Fundamentals of Quantum Theory, this physicist explained to me why Europe does not rivate today with the USA or China, when you could do it. As we have seen, the old continent had the scientific advantage in this field, but lost it because within just five years a few international companies and laboratories invested a lot of money in strengthening a few groups and got an exponential advance in this area. This reminds us how important it is to observe that it is strategically interesting and not lose that track. This field was built by Europe. Just two and a half decades He stayed behind. “Probably the fault is of our scientific fabric, and, above all, of our business fabric, which is less innovative and costs him more to get into this type of risky lines,” Juan José García Ripoll holds. In Europe there are companies that are dedicated to quantum computers. The Austrian Alpine Quantum Technologies, the Finnish IQM, the British Oxford … Read more

Meta has a very long history by replicating rival applications to become gold. Edits is the most recent case

by

If you have opened Instagram throughout the day, you are likely to find reels or stories talking about Editsthe new finish line focused on short video edition. It was an expected response to Capcutmore than welcome to offer an alternative to an application that barely had rivals in the market. Beyond the app, which is still a free Capcut clone with less functions (at least in this initial easy), the key point of this launch attends to a strategy that has been running for years: copying to kill. Edits arrives at the right time. Instagram has had a lot of time to launch a video editing application. But, as usual, he has done it with him Timming more precise possible. In mid -January the government of Donald Trump Baneaba Tiktok And, next to her, Capcut. Just a few hours after the baneo, Tiktok He returned to apps stores with an extension that is still in force. But little or nothing was discussed that Capcut was never available again. It has been right now, in full uncertainty what will happen to the apps of Bytedance (company behind Tiktok and Capcut), when Meta has decided to launch edits. The goal only cares about creators. Content creators are the pillar that supports apps such as Instagram and Tiktok. And there is quite curious data in this regard, according to data from Sefici. The Nanoinfluencers (less than 10,000 followers), have a 5%participation rate, the highest. The microinfluencers (from 10,000 to 100,000 followers), 4%. The macroinfluencers, with more than 100,000 followers, are 7% in participation. Why is it important to understand this? Because in the business model of this social network there are many users consuming content (and advertising), but few creating. And it cannot be consumed if there is nothing created. And want to take them to your land. Capcut is the third more downloaded application in iOS worldwide (nine million downloads) and the ninth on Android (18 million downloads). In combined, 27 million users and the seventh application worldwide, above Telegram, Snapchat and Threads. They are barbarian figures for a video editing app. Instagram has especially optimized edits so that the videos uploaded from this app have the highest quality. Additionally, it has integrated creator statistics into the app itself so that creators have access to the panel from edits. Something very similar to what Tiktok does with Tiktok Studio. It is a shout to heaven so that creators stop using the bytedance tools (payment in the case of Capcut Pro) and begin to move towards the finish lines. Copy to kill. There is something that Meta knows how to do very well: copy functions. He did it in 2016 by launching Instagram Stories, A frontal blow (an almost accurate copy) of Snapchatbut integrated into an app with many more functions. Instagram Stories did not take Snapchat in superior active users, becoming one of the main monetization tools of the platform. Today, an ad is displayed every three stories. Next to nothing. In the case of Tiktok, Reels He has not managed to steal user base. But, again, Meta took the opportunity to copy a winning and emerging idea (the videos in short format), to get a new monetization tool. A golden opportunity. Today, Instagram is still the only real competition for Tiktok. If the app fails to survive in the United States, victory will be overwhelming (it is its second market outside of China). And there, as usual, goal will be prepared to bring all the functions and tools that were already present on the rival platform.

We have been discussing whether it is a good idea or not bassinally during long flights. Crews are clear

by

May not reach the level of the debate of whether the tortilla It must or should not carry onionbut when we talk about airplanes there are A dilemma that arises in virtually long flights: barefoot or not barefoot? Is it justified to take off your shoes to make a transoceanic flight of more than eight hours more? Is it uncivic? Is it unsafe? To start, do companies allow it? The debate jumps From time to time In networks. And surprising analysis and Surveys That is good to keep present. Travel and shoes. If you take the train or plane frequently, especially for long journeys, you will have seen it A few times (You may even do it yourself): There are passengers who, according to the trip, take off the shoes to be more comfortable. There are those that stay in socks. And others that directly leave their naked foot. It is a relatively common stamp. Just as it is to see how other passengers from the car or plane begin to look at those feet with anger. Click on the image to go to Tweet. A figure: 56%. It may seem a minor issue, but the flights (and train trips) with or without shoes is relevant enough for companies that have dedicated themselves to studying the topic thoroughly. An example is the Kayak platform, which in 2023 published A report with “the tacit rules” of air trips in which he collected the opinions of passengers on issues such as the use of support and players or telephone calls One of the issues he asked in his survey was the footwear in the planes. Are you okay if the flight is long? He obtained two answers, to each more striking. The first is that at least among the Americans there is no A clear opinion on whether it is correct or not take off your shoes on the plane. 56% believe that passengers must remain shoes, but as Slide Kayak itself That supposes that there is another 44% that differs from that opinion. Moreover, according to their data one in five people believe that it is fine to go to cleaning without shoes. Socks, the red line. In what is much more unanimity is that, although a traveler removes the shoes, heels or shoes, what he should never do is get the socks. 76% Of the surveyed by kayak it does not see that people dare of that garment in the airplanes. The percentage exceeds even those who consider that phone calls should not be made inside the plane or that to listen to music or watch movies you have to wear headphones. “It is unpleasant”. In other countries opinions are much more categorical. A while ago Jetstar made a similar survey Among more than 20,000 travelers and found that the majority “unworthy” that there are people who walk barefoot through the airport. The idea only convinces 6% of Australians and 9% of the Japanese. “An airport or plane is not a private living room,” says Zarife Hardy, responsible for the Australian School of label. “Remove your shoes in crowded spaces is coach for others.” In your opinion, you can get your shoes acceptable if we talk about long journeys, during which the traveler spends hours and hours in her seat, but Zariffe remembers That does not mean that I should be with the naked foot. “Wait for the plane to be flying and wear socks or slippers,” he advises. Education question … and personal hygiene. There is another reason why we should think twice if we should get our shoes on a plane. We may win comfort, but in the long run you can carry more serious problems. Especially if we are still barefoot when we want to go to cleaning. “On long -term flights I have realized that people (often children) walk barefoot towards or inside the bathroom,” Explain Jagdish Khubchandani, Professor of Public Health at New Mexico State University. “It is a very antihigienic trend with infection potential if someone has cuts or wounds.” “Sometimes it’s not water”. In case there were doubts about it, Leysha Pérez, regional flight assistant, even went further in An interview with Business Insider in which I explained why moving barefoot through a plane may not be the best idea in the world: “Sometimes what you see on the bathroom floor is not water. Surely body fluids are what you step on.” There are airline crew that directly They confess That “they would never” go barefoot to a bathroom, however long the flight is. “Walking on the barefoot or socks is disgusting,” They underline. And what do companies say? There are cases where traveling barefoot is not even an option. The reason: the airlines themselves prohibit it in their use policies. For example, American Airlines establishes Clearly that all its clients must dress in “appropriate” aboard their ships, and if there were doubts about it adds: “No bare feet or offensive garments are allowed.” Something similar occurs with Hawaiian Airlines, which remember that your staff can refuse to transport a client if you do not meet “the Hawaiian standards of clothing.” And that, clarifies, implies wearing “safety” shoes.

Astronauts have become very different from space after a long period outside the planet

by

In June 2024, NASA Astronauts Butch Wilmore and Suni Williams arrived at the International Space Station for a mission of 8 to 10 days. However, the Starlliner ship problems They delayed their return Until March 2025286 days later. What began as a short stay became more than nine months of microgravity, which It can have deep effects In the body of astronauts: muscle atrophy, loss of bone density, cardiovascular alterations, vision and stress problems. This was its appearance before being thrown into the space in the Starliner ship: And this is its appearance when returning in the Crew Dragon ship that rescued them: Decades of aging Both NASA Like ESA They have studied in depth the effects of exposure to space and microgravity on the human body. One of the most common is the loss of muscle and bone mass. In the International Space Station there is no severity that forces the muscles and bones to work to sustain the body, so the tissues begin to weaken due to disuse. Astronauts lose about 1% bone mineral density for each month that pass in space. Their muscles, especially those of the legs and back, end up atrophy, hence they have trouble standing after landing on earth. To mitigate this effect, the ISS crew are subjected to railway routines: two hours a day on the running tape, static bicycle or resistance exercises. But it is not enough: a study published in Scientific Reports revealed that a stay of more than six months in space can cause bone losses equivalent to decades of aging on Earth. It is common for astronauts to have a greater risk of fractures due to the lower resistance of their bones, as if they were elderly. For Butch and Suni, with an expected bone loss of 9-10%, NASA has established An intensive 45 -day physical rehabilitation program. Even so, for many astronauts the recovery is incomplete even one year after returning. It is lacking two to four years for the muscles of a person to fully recover their original strength after a prolonged mission. Effects of microgravity Upon floating, body fluids are redistributed to the upper body, since gravity does not throw them towards the feet. This causes the swollen face feature seen in astronauts aboard the ISS. But it also has internal consequences: the body interprets that there is excess fluid and reduces total blood volume. With less blood volume and without the need to pump against gravity, the cardiovascular system relaxes. The heart can lose weight of its muscle walls and blood pressure tends to fall. Upon returning to the ground, this adjustment sometimes cause dizziness or even fainting (orthostatic hypotension), since gravity takes the blood again to the legs, and the bodyIt takes time to fall. Astronauts often use special compression suits or increase fluid and salt intake before the reentry to minimize these symptoms. Even so, it is common for them to remain seated, as happened with Butch and Suni when you get off the Crew Dragon, waiting for your body to be rebuilt. Another important physical effect discovered in the last decades of space exploration It is the so-called neuro-ocular syndrome associated with space flights (Sans). Without gravitational attraction, the displacement of fluids to the head can increase intracranial pressure, which in turn slightly deforms eye balloons and compresses the optic nerve. Many astronauts in prolonged stays report changes in their visual acuity: they can develop temporary farsightedness (difficulty seeing closely), which means that their eyes change under internal pressure. In long -term missions, More than 70% of astronauts They have come to suffer Sans. NASA Astronaut Scott Kelly, who spent a year in space and then be compared to his twin brother Markdeveloped an edema of the optic nerve and changes in the retina. Prolonged ungrampidity and the closed environment of the ISS also They affect the immune system of astronautscausing changes in the distribution of white blood cells and in the Expression of certain immune genes In response to the extreme environment. Paradoxically, living in the sterilized environment of ISS can weaken the immune response over time: by not exposing yourself to so many everyday pathogens, the immune system lowers the guard. Cutaneous eruptions, allergies and even reactivation of latent viruses (such as herpes) have been observed due to the decrease in defenses. Radiation and nine months of stress At the same time, prolonged missions astronauts accumulate significant exposure to Solar radiation and cosmic raysnot having the atmosphere as a protective shield. However, a nine -month stay is within the acceptable limits of NASA, since the ISS orbit the Earth only 400 km of altitude. Cell damage It will be a much greater problem In future long -term space flights to the moon and Mars. More worrying are the Psychological effects of prolonged confinement in a space station that orbits the earth 16 times a day. The schedules are not a problem because the ISS follows a strict time routine with the time of the Greenwich meridian. But the lack of natural cycles of light and dark can alter biological rhythms, cause sleep deprivation or reduce cognitive performance. In the end, what can happen more invoice is the psychological experience of being working in a confined environment, far from the family and with a handful of classmates from different countries. In the case of Butch Wilmore and Suni Williams, this situation was aggravated by uncertainty: its mission was extended due to technical problems, for a long time without a clear return date. Hence Wilmore’s daughter will mention stress Like a problem. The good news is that most body changes in space are not permanent. Approximately 95% of physiological alterations return to normal in the weeks after return. Astronauts typically recover their balance and ability to walk in a few days, fluid distribution is rapidly normalized and sleep disorders tend to improve by reestablishing terrestrial cycles. As for psychological sequelae, career astronauts are chosen for their predisposition to be rendered under … Read more

Its protagonists are humanoid robots and goes for long

by

China is openly promoting the development of humanoid robots as its next great technological revolution after its success with electric cars. A few days ago, according to NikkeiShenzen activated a plan that includes financing and political support to promote advances in components, AI chips and biomimetic technologies. Why is it important. It is a movement that coincides and much with Elon Musk’s plans with Tesla, whose Optimus robot It could begin its production at the end of this year, first for internal use and then to market from 2026. This convergence has a lot to do with the entrance of Tesla in China and the effect it had when transforming its electric car industry. In figures. 56% of the 100 traded companies dedicated to robotics are based in China, according to A Morgan Stanley report. In addition, 45% of companies that customize robots for the end user are Chinese. The context. This plan is accompanied by several similar initiatives since 2023. Shanghai wants to create a 1 billion yuan robotics industry (about 137,000 million dollars) this year. While, Beijing has announced a fund of 13,000 million dollars for robotics and a humanoid innovation center. Paul Gong, head of automotive research at UBS Investment Bank, Describe To Musk as the “spiritual leader” of the sector, a paper that also played with electric vehicles. “The introduction of the concept of humanoid robot has led many Chinese companies to explore this address,” he says. The threat. The intensification of geopolitical tensions could have consequences. Lu Hanchen, director of Shenzhen Gaogong Industry Research, warns that the United States could restrict the export of optimus robots to China and block the entry of Chinese humanoid robots into the US market, referring to concerns about data security and data management. And now what? According to Bernstein Research projectionshumanoid robots could reach: By 2025: less than 10 million units for entertainment, R&D and education. By 2028: tens of millions for specific tasks in general environments. By 2035: more than 100 million for general tasks in hospitals and restaurants. By 2050: more than 1,000 million performing most human work. The collaboration with Chinese suppliers will be basic for Tesla. At the same time, Chinese companies will move trying to reduce foreign component dependence. It is an interesting paradox: Washington and Beijing have an increasingly tense relationship, but at the same time their industrial ecosystems remain intertwined. The race for humanoid robots is intuited as another scenario in which mutual dependence and atrocious competition between both blocks will have to live together. And the figure of Musk will win integers in that clash. In Xataka | Unitree is one of the Chinese technological jewels.

My concentration ability takes a long time. Working in a laptop almost 15 years ago has saved me

by

Our care economy is broken. Completely. We are continuously bombarded by stimuli that come by many ways and the consequence is clear: We distracted ourselves with the flight of a fly. It is curious how this is causing a change not only in us, that we look for methods not to distract us, but in elements such as an entertainment industry that has changed its way of capturing our attention. There are two very clear examples of this. Music is one more or less obvious, with increasingly short songs (just a couple of minutes) and, some, with the chorus as the beginning of the theme. In addition, these choruses are also short to fit in the 15 seconds that you can share in an Instagram story. Another example is that of films, with trailers of a couple of minutes that begin with a trailer trailer itself. Here are an example of ‘TOP GUN MAVERICK‘, whose trailer starts with a five -second teaser with images that we will see below: Many more films make this, being a marketing resource that begs us to Let’s pay attention For two minutes. They seem to beg a “Please, pay attention to me, cool things come”. Due to that constant information bombardment, We seek to be productive when we are hyperstimulated And we read books, we learn from successful people, we put into practice supposedly infallible methods, we download applications and, sometimes, we spend more time looking for how to be productive That, really, being. I have to say that I have found a secret to Improve my productivity: Working on a computer that prevents me from opening more than three tabs at the same time. And – at least to me – it works. A hardware barrier If you are reading this it is because you have looked for ways to be more productive and not distract you. I have done it and I have installed everything on my computer, I have configured Ways not to bother the phone And even issues that restrict apps during work hours, but the meat is weak and the finger always tends to go open Bluesky or worse Instagram and Tiktok. One day it occurred to me that, if the software did not limit me, perhaps the hardware would. I went to the closet and took out of the box (I am one of those who keep the boxes of what he buys) My university laptop: a 2011 MacBook Pro. 16 GB of RAM A double -core i5 at a few 2.4 GHz and 13 inches of screen. Years ago I replaced his hard drive with a SSD and I was surprised to light after so many years. What did not work was the charger (nothing that does not solve Amazon and some 20 euros), so I configured it and came across the first problem: I was very outdated. Not only could he not update to a new operating system, but browsers such as Edge, Chrome or your own Safari They were insuffically slow. Nor could I install some applications that I use on a day -to -day basis, such as Notion, because they require a more recent version of the system, so I did with a Firefox Legacy and configured it so that Notion Be the default opening page. You will be wondering why I tell you this, and there I go: when I changed this laptop for a more recent one in 2017, something was already slow and having more than 4-5 tabs in a browser was unfeasible. Despite the 16 GB of RAM, the processor could not with so much without making the fan a turbine, without heating the chassis and without making the system on pull. Precisely, the reason that forced me to make the leap to Infame Macbook Pro with butterfly keyboardIt is the one that made me come back because I wanted, precisely, that. I explain: when I work on a website like Xataka, I do it with a lot of open eyelashes to search for sources. I have Telegram installed, YouTube Music, an image editor and Many times I open, almost by inertia, some social network Or youtube if I don’t feel inspired. With issues such as news or reports, having that overestimulation does not bother me because I know it is something that will take me for a while and then I will happen to something else, but the thing changes when I have an analysis or an opinion article. Does the screen divided there? Neither joke For this type of texts, the concentration is key. You have to turn your thoughts and structure them in a certain way. You cannot afford to get distracted because you lose your thread, and those distractions do not exist with a laptop from almost 15 years ago. If I have more than three tabs open at the same time, the Mac goes to the idle, so I only have notion, Perplexity (precisely to look for something and have many options in a single tab instead of many sources in many tabs) and YouTube Music. Web Telegram It is not an option, for example, and as soon as I have four tabs, the processor is already asking for rest. That with four Firefox tabs That technological barrier, almost physicalnot only does it exist because of how the Mac would go if I open more eyelashes: the screen also plays a paper. 13 inches are not bad and many current laptops have that diagonal, but here the resolution is 1280 x 800 pixels. Translation: scarce, much, so much that putting a game is not an option. Not having a high resolution, putting a split screen is unfeasible, which forces me to have a single screen I am writing, preventing you from having an eye in my text and another in a YouTube video, for example. As I said, it works for me and it is something that I have incorporated into my work routine. … Read more

The culmination of a long biotechnological career

by

Gives vertigo to think that the first artificial breast prostheses They were glass balls or that at the beginning of the nineteenth century Sanguijuelas were used to reduce venous congestion of skin flaps. The world has changed so much (and so fast) that we are not usually able to see the enormous feat they hide some antiojeras patches of 3 euros and 50 cents. And, sincerely, it is a huge mistake. Which hides a patch of the Mercadona. Because the fact that Some “masks” of hyaluronic acid are viral It may seem a curiosity. However, there is a lot of cloth to cut. In a dialogue that has not become famous, but that should be, Miranda Presley tells the protagonist of ‘The devil wears Prada’ that “I understand, you think this has nothing to do with you. You go to your closet and select that deformed blue sweater because you try to tell the world that you take too seriously to worry about what you will wear. But what you don’t know is That Jersey is not just blue, it is not turquoise or marine: it is cerúleo. Exempt from the fashion industry when, in fact, you carry a sweater that was selected for you by people like us. “ This (which is true with the fashion world and with elite restaurants) is exactly like that with aesthetic medicine and contemporary cosmetic industry. After a very cheap patch and A couple of tips to go perfect to the next wedding There are not only “millions of dollars and many jobs”, there is an exciting scientific and technological history. And hyaluronic acid is a great example of all this. Isolated for the first time in 1934, hyaluronic acid is A high molecular weight polysaccharide that is present naturally in our body. An adult human being has, on average, about 15 grams of Ah and, around a third, is renewed daily. Above all, we can find it in the synovial fluid of our joints; But it is In many more placeslike the eyes, the extracellular matrix of cartilage and tendons and the skin. We still do not have very clear all the functions it has in the body, but we do know that it has a key role in maintaining the structure of many tissues, homeostassis, cell hydration and wound regeneration. This is key because, over time, a loss of human connective tissue and its repair processes “that have a lot to do with it is suffered. And the skin is the place where it shows the most. Use hyaluronic acid Help mitigate these problems. We have known that for a long time. Moreover, we knew that (being part of the ‘natural’ substances of the human being) had a very high biocompatibility index and almost no dangerous (or durable) side effect. However, its first commercial use in the 40s was like Egg whiting substitute. The problem for decades was the same: we could only take out the hyaluronic acid from sites such as shark cartilage or clogs of the roosters. fabrics sufficiently rich in this component so that its extraction was ‘cost-effective’. But manufacturing techniques involved a risk of considerable allergy. The hyaluronic boom (and what you have behind). It was not until the early eighties that a first medical product that contained it achieved its approval. Of course, it was Ophthalmological surgeries oriented (cataracts) and had no cosmetics ends. For that we have to wait until 1996 when it begins to be used as a dermo-epidermal moisturizer; But, above all, what The techniques that allowed to manufacture it using genetically modified bacteria were refined. Towards the Nano. It is the perfect metaphor to talk about what is happening with aesthetic interventions. As science advances, that surgery becomes a micro (or nano) that the pharmacology learns to create better molecules and develop better ways to administer them … aesthetic medicine has ceased to be something dangerous, frivolous and niche, for become the “our daily bread” of huge age cohort. The Arrival to the Senectud from the Baby Boom generation (and the economic power they have) does the rest. The science of “rejuvenating your face” is a huge business. And, for the first time in a long time, biotechnology is prepared to offer more than mere placebo. In the same way that modern medicine banished thousands of remedies of doubtful utility, modern biotechnology will change skin care (and the rest of the body) forever. Although, of course, it is not just older thing. Among young people, all this He has also shot. It’s about a social changeYeah; but propitiated by a revolutionary technological change. Every day that passes the techniques become more ambulatory, less intrusive, more effective. Every day that passes the separation between ‘makeup’ or ‘taking care of the skin’ and aesthetic medicine is smaller. Every day that passes the “Rejection science“It’s close to being massive and extremely cheap: democratic. A culmen. That is to say, The patches that Mercadona sells to three and a half euros They are the summary of a very long scientific and technological career of decades that has traveled almost the entire modern industry from the agri -food to genetic engineering passing, of course, through the Aesthetic surgery and regenerative medicine. But, above all, they are a symbol of the times that (With the good and With the bad) They have touched us to live. In Xataka | Some researchers say they know how to end the gray hair.

Football is causing real chaos on the Internet. Not directly, but due to LaLiga’s obsession to avoid illegal emissions of the parties. The particular crusade of this body against these emissions comes from afar, but is beginning to cause real problems to users and companies that have nothing to do with the problem of these illegal emissions. War against IPTV Yy El Cardsharing. In December 2021 the Commercial Court No. 6 of Barcelona He issued an order aimed at the immediate blockade of domain names belonging to several IPTV and Cardhsaring suppliers. The court authorized LaLiga and Movistar+ to monitor web pages blocked throughout the season to identify possible changes in their identification, but they could also request the blockade of new domain names weekly. These requests should be executed by Internet access providers. Said blockages had already been executed In February 2020 After a sentence of the Commercial Court No. 7 of Madrid. Weekly locks. In August 2022 LaLiga and Movistar Plus+ They won a lawsuit Joint before the Commercial Court No. 9 of Barcelona that enabled them to “be able to block access to domains that facilitate the piracy of LaLiga content.” The “dynamic block” measure It allows URLs, domains and IP addresses to be identified weekly without communicating them previously to the Court. It was already decided that it would be in force until the current 2024/2025 season. Attempt to pursue user IPS. In March 204 LaLiga made it clear that I wanted to chase those users They see football by IPTV applications not allowed. A judicial order raised the possibility of track the IP addresses of those who profit economically with that activity. He precedent of the Euskaltel case Years before marked a turning point in this type of demand by content suppliers. Telegram lock attempt. That same month the National Court Ask to block Telegram in Spain to operators. The platform has become On the new Deep Weband through it all kinds of content are shared, even those of emissions that violate the copyright of their owners. Finally The blockade did not occur. LaLiga against Freedom on the Internet. In April 2024 the company He loaded against Google, Apple and Huawei As owners of application stores from where the NewPlay app could be downloaded, one of the IPTV apps accused of violating their rights. 450 euros for using the IPTV. LaLiga continued her particular crusade against freedom on the Internet and in June 2024 requested by letter 450 euros To users who had accessed IPTV to see LaLiga content illegally. Tracking UPS IPS. Just a month ago the Commercial Court No. 9 of Barcelona authorized LaLiga to receive Information about IPS connected to Acstream. A preliminary diligence requested by the League was agreed, which consists of: “sending to the operators of the IP addresses identified and ordered based on the ID of the” Ace Stream “channel in which they participate.” Criminal Procedure Law. This law includes in its article 13 the “provisional interruption of the services offered by said contents or in the provisional blockade of each other when they lie abroad.” However, its affectation to a fundamental right such as freedom of expression, and also these measures, which involve IPS blocking, are being carried out in certain cases in a seemingly indiscriminate manner, affecting both legitimate sites as to sites that are not. The reason is that platforms such as Cloudflare use IPS that share all those services. How illegal retransmissions are detected. The way to detect and knock down web domains that broadcast soccer matches illegally has changed a lot in recent years. In LaLiga they make use of Tools like Marauder, Lumière and Blackhole For these tasks, and said software It has generated interest internationally. IPTV as such are legal. NewPlay is one IPTV to use. Base are a completely legal type of application. They are still decoders of M3U lists. For practical purposes a kind of VLC -style player. While LaLiga accuses this type of applications to be used to reproduce content without permission, such as football matches. In addition, the Supreme Court has already established that football has no intellectual property. But the indiscriminate block of IPS is terrible. What is happening is that among the IPS that are blocked there are IPS managed by Cloudflare that are not dedicated to a single service, but are shared between tens, hundreds and even thousands of them. If the Internet supplier does not relate a selective block, when blocking the IP, it not only prevents access to who offers illegal content, but also to the rest of the services that are totally legitimate. Cloudflare does not make it easy. Cloudflare makes use of techniques such as ECH (Encrypted Client Hello) to protect the privacy of websites that share that IP, which makes the filtering of each other and the execution of a selective block. However, some operators like Vodafone They confirmed to Xataka Mobile that these days they applied a block “much more precise and adjusted to LaLiga’s request” although they did not give details about it. Movistar’s clients complained precisely that They were affected by indiscriminate blockages that prevented them from accessing numerous web sites and services.

The Persian Gulf has dominated the long era of oil. Now he is preparing to lead the era of solar energy

by

There is an increasingly more and more evident energy change, and even the countries we would never think are jumping to the renewable pool. Yes, I talk about the countries of the Persian Gulf. However, the tests are there: seven Chinese solar companies were generating more energy capacity than the world’s greatest oil companies. So, now, with their money and a lot of sun, everything indicates that they will give sorpasso. Wild investment. For very recently, Gulf countries have decided to invest in renewable projects. On the one hand, the United Arab Emirates They have announced a solar project 5.2 GW with a battery system, also betting on storage. On the other hand, Saudi Arabia is developing its energy transition plan through the Vision 2030 Plan. Recently, the Saudi Aramco oil giant has announced an agreement to start producing lithium in 2027. In addition, They are developing a plan to extract and enrich uranium For nuclear energy. Likewise, the Saudi country is carrying out different solar energy projects, some in Collaboration with China and others with Spain. And we can’t forget Kuwait, who already started two years ago has develop 17 GW of renewable energy and 25 GW capacity for the production of green hydrogen, which propose to export it to international markets. Data. According to the recent report by the International Renewable Energies Agency, the Middle East has Less than 1% of the world’s renewable capacity. However, from the agency they have detailed that the forecast for the next few years will be of accelerated growth. For its part, An analysis of the consultant Rystad Energypoints out that within five years, more than 30% represents total capacity in Gulf countries such as the United Arab Emirates, Saudi Arabia, Bahrain, Kuwait, Oman and Qatar. From the consultant they detail that this impulse is due to the weather conditions and the favorable conditions of the market. New solar panels will boost electricity generation in the Gulf Favorable energies. In the graph of Rystad EnergyWe observe that the Persian Gulf has two very different parts. The colored areas of orange, blue and green that represent renewable energies we see how they increase exponentially, especially solar. However, we see how nuclear and hydrogen have a slight growth that is maintained over the years. On the other hand, oil and gas, colored gray, although they are currently the main sources of energy, they will fall by 2050. China, ally or competition? The Asian giant has become a double agent in the energy transition, acting as much as a partner and competitor. On the side, Chinese companies such as Jinko Solar, Longi and Byd are providing solar panels, batteries and other technologies for the ambitious renewable projects in the desert region. On the other hand, China is carrying out the development of its own solar and wind projects. Besides, Your dominance over the global supply chain of batteries and solar panels gives you an advantage in the energy market. At the same time, its expansion in the Middle East allows you to gain influence in a region that has historically been dominated by fossil fuels. The change. The Persian Gulf is in the process of investing in renewables to mark its path to sustainability. However, they still have a stretch to travel because infrastructure and energy supply stability are still aspects that must be resolved.
