solution

China has understood better than anyone where the space launch bottleneck is. Your solution: the sea

by

On April 18, China will launch a space rocket from open waters for the first time. The Dong Fang Hang Tian Gang vessel has been modified to function as a launch platform, minimizing many of the problems that terrestrial platforms currently represent. The facts. This aquatic launch platform is a vessel that measures 162 meters long and 40 meters wide. The Jielong-3 rocket will be on board31 meters, designed by the Chinese Academy of Launch Vehicle Technology for commercial flights. It will be launched from the South China Sea, marking the first time a launch has been carried out from open waters. If all goes well, China’s goal is to make it far from the last time. A huge waiting list. China has decided to launch rockets from the sea to address various problems. The first, without a doubt, is the saturation to which conventional launch platforms are currently exposed. The rise of the satellite industry, both for telecommunications as with other crazier purposeshas led to more and more launches scheduled on all launch platforms around the world. As a result, each new release must go onto a long waiting list, which can get complicated when you consider that there is usually only a few days’ release window available. It’s cheaper. Another advantage of aquatic launch pads is that they are very easy to build. To build one on dry land it is necessary to acquire a large amount of land and install all the necessary infrastructure. The result is not only complex. It is also very expensive. In the sea, on the other hand, a platform adapted to the immensity of the ocean is enough. Also safer. On the other hand, these types of offshore launch platforms are much safer than land-based ones for several reasons. To begin with, methane is increasingly being used as fuel. It is very powerful, but also very explosive. Therefore, large safety zones must be established around the launch pad. This is vital in case of an accidental explosion. In the ocean, however, it is not necessary. On the other hand, space launches cause great noise pollution for surrounding populations. If we add to all this that they could suffer the risk of falling parts, the truth is that living near a launch pad is not almost anyone’s dream. All of them are problems that are solved by launching rockets in the middle of the ocean. If there are accidents, the pieces must be removed to avoid contamination, but at least there are no populated areas that are at risk. The rocket to be launched will be a Jielong 3 Proximity to the equator. As a bonus, the ability to move barges wherever needed makes it easier for the Chinese Academy of Sciences to take its launches closer to the equator than land enclaves allow. This is very advantageous, since at this point the benefit of the Earth’s rotation can be maximized, giving greater momentum during launch. It’s not the first time, but there is a nuance. Actually, China has already launched rockets from water platforms in the past. A good example of this is Ceres-1S, which even used the same boat. Gravity-1 was also launched from a cliff. However, there is a difference. While Jielong-3 will be launched from open waters, Ceres-1 and Gravity-1 were launched near the coast, with logistics controlled from land and some of the same drawbacks that a land launch would have. A launch from open water, far from the coast, is another step forward. China continues to advance. In recent years, China has been positioning itself as a major space power. Just look at the progress it has made in lunar exploration. His plan to take humans to the Moon advanceswhile that of NASA does not stop finding impediments. Furthermore, its space station, Tiangong, continues receiving astronauts at a good pace, robotic exploration of Mars It is quite advanced and even They have found in Europe a great partner to explore solar inclemencies. Having an aquatic platform that gives agility to your throws can be another big step forward.

Australia has a problem: extremely boring and monotonous roads. And it also has a solution: sign trivia

by

If you drive on Australian roads you may come across unusual signs and we are not talking about the kangaroos warning (that also), but the one that warns you that you are about to cross the “90 Mile Straight“, a stretch of almost 150 kilometers in a straight line that means spending just under two hours without turning the steering wheel. Or a sign that directly throws you a random question typical of Trivial. The objective is that your brain does not disconnect because on such a monotonous route, boredom can be lethal. In fact, Australia has some of the most dangerous roads in the world and it is not because of their poor condition or their dizzying curves, quite the opposite: they are too long, too straight and too empty. So the country is exploring different solutions to avoid this potentially deadly drowsiness. Boring Australian roads. All of these roads have decent pavement, a predictable layout, a landscape with little variation and little traffic, a recipe for disaster: The Eyre Highway takes the cake: it connects Western Australia with South Australia across the plain Nullarbor Plain (which takes its name from the Latin: treeless) between Balladonia and Caiguna: 200,000 square kilometers of limestone land with hardly any vegetation or hills. A 146.6 km straight line without a single curve that you have to travel at 110 km/h (the legal limit in most of the country). After the Saudi Arabia Highway 10is the second longest straight road in the world. The Stuart Highway It crosses the center of the continent from north to south, from Darwin to Port Augusta, traveling more than 2,700 kilometers inland on a fairly simple route that also crosses the Northern Territory. There it has large stretches through northern areas with distances up to 252 kilometers Between gas stations, temperatures of up to 45 °C are reached and a landscape monotony that has little to envy of the Nullarbor. In fact, one of the roads with the highest rate of fatigue accidents in the country, according to the Australian government. The Barkly Highway It connects Queensland to the Northern Territory via the Barkly Tableland, a flat, arid plateau where the road stretches almost straight for hundreds of kilometres. The extreme heat, the total absence of shade and the sections without signage or rest areas make it a minefield for those who travel through it. The Flinders Highway Also in Queensland it runs through the interior of the state for more than 800 kilometers. It connects Townsville with the interior through a repetitive landscape, with little traffic and long distances between towns, the ideal breeding ground for boredom. At night it is even worse. The danger of road hypnosis. The highway hypnosis or white line fever is more than just being bored and drowsy: it is an altered mental state that allows you to continue driving, responding to basic stimuli and maintaining speed, but without being aware of what you are doing. Simply put: put your brain on automatic mode. science has an explanation: Flat, straight roads with little landscape variation produce a chronic deficiency of sensory stimulation, reducing alertness to dangerously low levels, causing drowsiness and inattention. This study on the phenomenon explains that cognitive fatigue reaches its peak just 20 minutes after entering that monotonous environment, much sooner than it might seem, even for those who are driving. When the brain warns, it has already been on autopilot for a while. The consequences can be tragic: unconscious speed increases or a minimal reaction capacity that already causes havoc. In Australia, fatigue while driving is four times more likely as a cause of this road hypnosis than drugs or alcohol. In Queensland, it accounts for 20 to 30% of road deaths. A15, Queensland. Via Google Maps Trivia on signs. The solution that Australian authorities have been implementing for years is so simple that it is shocking: posters with a question and answer game. As you enter one of those boringly dangerous areas, you come across a yellow sign that warns: “Fatigue Zone. Trivia Games Help You Stay Alert” (Fatigue zone. Trivia games to help you stay alert). From that moment on, you will find signs scattered along the route several kilometers away with a question and his corresponding response. Example: Question: Who was the first Premier of Queensland? Answer: Robert Herbert. And so on. The cognitive mechanism is exactly what science describes: introducing an unexpected and irrelevant stimulus for driving that forces the brain to come off autopilot. So the driver has to read, process the question, remember and, if there is a co-driver, even debate the answer. And then wait to see the solution a little later. A simple but effective way to activate the mind. Each question and answer is glued to the panel and secured with a padlock, allowing them to be renewed. And does it work? Well, probably yes, but no one has rigorously measured it. However, in theory the mechanism is supported by neuroscience. Professor Narelle Haworth, Director of the Center for Accident Research and Road Safety Queensland, endorses his presence: “Always doing the same thing, without much stimulation, causes a decrease in alertness (…) The idea of ​​trivia games on the road is to keep drivers more attentive… perhaps a passenger who knows the answer will start a conversation.” But Haworth herself acknowledges that although the objective is in line with road safety research, there is no study that has specifically analyzed the impact of the signs. In addition, it has its limitations: the signs lose effectiveness with those who travel the same route frequently and already know all the questions. And obviously they have a quite common risk in these times: Someone might think to look at their cell phone to look for the answer. And in any case, it does not replace rest. Triple animal sign.

Looking to reduce fossil fuels in transportation, Hyundai has the solution: a nuclear container ship

by

About 80% of world trade is moves by sea. Although it may seem like slower transportation, something key to maintaining prices is moving a large amount of material on each trip, something that is out of the reach of trucks, trains and planes. There, the huge container ships They lead the way with the associated problem of enormous spending on fossil fuels. The industry is looking for alternatives to operate no carbon emissions and Hyundai has a clear path. A nuclear container ship. Pioneer. HD Korea Shipbuilding and Offshore Engineering is the naval branch of the company and, in 2025, they presented a model of container ship nuclear seeking to eliminate emissions of a large ship with electric propulsion powered by a small nuclear reactor. The reactor type would be an SMR with thorium-based fuel and liquid salt as a coolant. After months working on the plan, this 2026 HD and ABS (American Bureau of Shipping) they arrived to an agreement to jointly develop the vessel. This is something that is in the design and subsequent prototype phase, but the agreement between the two lays the foundations for the development of a ship that is expected to be the first nuclear container ship. 16,000 TEU class. The class of a container ship is measured by the TEU, or Twenty-foot Equivalent Unit. Basically, x number of 20-foot-long containers, 16,000 containers at a time in the case of the Hyundai ship. It is far from the 20,000 and 25,000 TEU vesselsbut it will be a step forward in the maritime mobility of the future. Furthermore, the ship will not need to be as massive as others thanks, precisely, to that nuclear propulsion. By replacing the conventional machinery of diesel engines, exhaust systems and huge fuel tanks with a nuclear compartment and electrical systems, there is free space to transport more containers while maintaining the ship’s compact size. Compact within what these monsters are. Armor. To guarantee radiological safety, what this ship must include is a double stainless steel tank shielding system designed to ensure that there are no radiation leaks to both the inhabited areas of the ship and the ocean. The liquid salt itself as a coolant will also act as a safety measure against reactors that require pressurized or boiling water. If SMR stands for ‘Small Modular Reactor‘, MSR respond to ‘Molten Salt Reactor’, and basically means that, in case of emergency, the salt mixture can solidify to stop the reaction, being another security measure. all the sense. For now, the Hyundai ship has received the approval of its partner – an advantage of being the body that is also in charge of these things – but it is a project. The next steps are development and prototype, so there is still no authorization for the construction of the ship. However, it makes perfect sense for container ships to switch to nuclear propulsion. It is something that we have already seen on large ships like aircraft carrier and submarinesand the main advantage (apart from reducing emissions) is that life on the high seas depends solely on how much food can be loaded on board. Obviously, the investment is more expensive initially because it is not cheap to change the mobility paradigm, but it would not be tied to fluctuations in the price of fuel for transportation, something that we have been seeing recurrently in recent years and that, obviously, changes the shipping price. Alternatives. Hyundai is not the only one in this race and its national competitor Samsung also has a project in the oven. China, or Norway, transport heavyweights, They also have concepts of container ships powered by nuclear reactors. In the end, the industry must move because the International Maritime Organization is regulating greenhouse emissions and demanded reductions of 20% by 2030 with the aim of achieving neutrality by 2050. A render of China’s nuclear container ship In that sense, maritime transport not only represents 80% of the transport of all goods, but is responsible for 3% of global CO2 emissions of human origin. Now, nuclear electric motors are not the only way and recently we are seeing that the industry is exploring the path of battery electrification and even the return of a technology that seemed forgotten: the candles.

Sleeping in on the weekend seems like the perfect solution to your tiredness. Your body has a very different opinion

by

Sleep eight hours a day religiously is for many a goal that they almost never manage to achieve, since the alarms sound too early and the days lengthen, accumulating a dream debt which we tried to settle on Saturday morning. But here the question is obligatory: are we achieving anything by sleeping 10 hours on Saturday? The answer. Here science has wanted to investigate the debate about whether doing this recovery sleep technique on weekends is useful or is a temporary patch. And the truth is that there are endless different options that mean we don’t have a ‘yes’ or a ‘no’. Cardiovascular shield. At first glance, science seems to agree with people who decide that the weekend is for sleeping, since several studies suggest that it is quite positive for our health. One of these analyzed more than 90,000 people and concluded that the group that accumulated more compensatory sleep on the weekend had a lower risk of developing heart disease. And more specifically, these people had up to 20% less risk of suffering from coronary heart disease. On the other hand, another study used data from the NHANES surveys carried out in 2018 and noticed an association between recovering hours of sleep and a lower prevalence of cardiovascular diseases, which is something that stands out especially in patients who slept less than 6 hours during the week. There is small print. In science there are contrary points, since researchers, when they affirm measurement methods and look beyond self-completed questionnaires, reality is more complex. Here is a study with 70,000 people who used accelerometers to objectively measure sleep threw cold water on previous evidence by pointing out that compensatory weekend sleep is not associated with lower mortality or fewer cardiovascular events. More alterations. Apart from all this, different scientific reviews point out that the evidence is heterogeneous, pointing out that sleeping more on the weekend does not always manage to correct problems such as insulin sensitivity, which is altered after previous days of sleep restriction. And it is known right now that biologically, lack of sleep triggers complex processes such as insulin resistancethe activity of the sympathetic nervous system and systemic inflammation. And all this cannot be fixed in a silly weekend of sleeping a few more hours, since a much longer sleep regulation would be needed to once again have an optimized biological system. Beyond the heart. Although we usually focus on the engine of our body, the reality is that there are effects much further than that. In the case of mental health, science suggests that weekend recovery carries a lower risk of depression. But other articles on health-related quality of life suggest that the “optimal” duration of recovery sleep is not the same for everyone, and can vary greatly depending on the sex and chronotype of each individual. The verdict. Right now science tells us that there is an association, but not a proven coincidence. In this way, trying to pay off your sleep debt on the weekend is undoubtedly better than continuing to sleep little seven days a week, but it is not a metabolic time machine. What you have to keep in mind is that the final effect will depend on how much deficit you carry during the week and how many hours you try to achieve, but in the end the medical advice that we should stick with is that the objective is to have consistency in daily rest so that it is as optimal as possible.

Iran has made energy a problem again. The United Kingdom believes it has found a solution in solar panels

by

There are issues that we believe are resolved until reality reminds us that they are not. Energy is one of them. We have been talking about for years solar panelsof self-consumption and of alternatives to fossil fuelsbut in many cases they remained a rather gradual, almost optional decision. That has changed. The rise in energy prices linked to the conflict in Iran has brought the problem back to the forefront and forced several governments to react. The United Kingdom has decided to act. The specific measure. What the British Government has put on the table is not a generic promise, but a plan to try bring so-called plug-in solar panels to stores in “the coming months.” To make it possible, the Government is working with Amazon, Lidl and the manufacturer EcoFlow. There is also an interesting nuance here: we are talking about an American e-commerce giant and a very recognizable supermarket chain in Europe. What makes them different. At this point, it is worth stopping for a moment on what exactly we are talking about. These plug-in solar panels do not work like a traditional photovoltaic installation, which usually requires construction, permits, and the intervention of a professional. The idea here is much simpler: smaller devices that can be placed on balconies, walls or gardens and connected directly to the home electrical network. According to the British Government, this approach would allow them to be used without the need for an electrician, as long as technical and safety standards are adapted. The context. It is no longer a secret that the conflict in Iran has hit one of the most sensitive points of the global energy system, the Strait of Hormuzthrough which a relevant part of the world’s oil circulates. When that flow is threatened, prices react quickly, and that is just what has happened. In a few days, crude oil and gas have risen sharply and that impact ends up reaching Europe in the form of more expensive fuels and higher bills, which has forced several governments to act. The European mirror. If we leave the United Kingdom, what we see is a map of quite diverse responses to the same problem. Rising energy prices have forced action, but each country is doing it in its own way. Spain has opted for a broad package of aid and tax cuts, valued at around 5,000 million euroswhile Germany has focused on regulating the behavior of gas stations and Portugal has applied fiscal adjustments more specific about fuels. Faced with these measures, more focused on cushioning the immediate blow, the British movement introduces another approach, facilitating access to alternatives such as solar energy to reduce dependence in the medium term.

The solution is to ejaculate every day

by

For decades we have had a very clear idea in our minds about male fertility: to have a good semen sample, it is necessary that there is a period of abstinence in which the man should not ejaculate. Now this idea has completely changed with a new review published in which this idea is now completely eliminated, recommending having to ejaculate at least once a day. What we thought. The guidelines that were conditioning a good part of human reproduction did not come from anywhere, but from the WHO itself, which today recommends between 2 and 7 days without ejaculating before undergoing a seminogram. A fundamental test to be able to see the quality of semen with the number of sperm and their movements. The new paradigm. The key research It was published at the end of this month of March and its conclusions leave no room for doubt that the protocols of fertility clinics must change sharply. To reach these conclusions, Oxford researchers They have not fallen short with the data, since they have integrated no less than 115 studies in humans, covering more than 54,800 men, and 56 studies in 30 animal species. This enormous amount of information, whose open data is available on the Dryad platform, has served to demonstrate a fundamental biological phenomenon: post-meiotic senescence. What does it mean. This term refers, in very extreme terms, to the fact that sperm ages and ‘spoils’ if it is stored for a long time. If we develop it a little further, the researchers point out that prolonged storage in men’s reproductive tracts causes greater DNA damage, triggers oxidative stress and drastically reduces sperm motility. But the most important thing is that this occurs regardless of the age of the man, or the male in the case of animals. In this way, the problem is not how old a man is to be able to have offspring, but rather how long that sperm has been ‘saved’. A paradigm shift. The Oxford findings, supported by different previous studies, clash head-on with the current guidelines that the WHO has and that are followed in many parts of the planet. In this way, if the sperm begins to suffer damage from oxidation and DNA fragmentation after a few days, asking fertility patients to wait up to a week of abstinence is counterproductive, since we would be obtaining a sample of poorer quality. Previous studies had already seen that abstinence longer than 3 days increases sperm DNA fragmentation by up to 50%, but when daily ejaculations are made, sperm vitality improves significantly. The conclusion. With all this information, Oxford points out that regular ejaculation, whether with sexual intercourse or masturbation, is the best way to guarantee high-quality sperm. This is data that is crucial not only for humans, but also for captive breeding programs for animals. But where this is going to mark a before and after is in fertility clinics, whether with couples who have problems having a child or even for those men who they donate their semenwhere you would also be getting a sample of lower quality than the real one.

A year ago, the blackout caused the Spanish data network to collapse. The CNMC believes it has the solution

by

In April 2025 Spain suffered a zero energy of which, precisely now, we are going to begin to pay some of its consequences. I remember quite clearly being cut off, not being able to call or send messages via data connection. However, when I changed locations and arrived at my relatives’ houses, some of them could do it. The fall of telecommunications It was uneven in Spainand the CNMC has published a document with preventive measures in case a similar situation occurs again. What happened. The energy blackout that left Spain plunged into darkness resulted in a large part of the population being cut off from communication. However, some operators They managed to keep their mobile network active for hours. Backup generators, generating sets moved to each area, backup systems… The challenge for operators to maintain coverage in Spanish territory was a titanic challenge, quite dependent on internal logistics, the state of the reserve batteries (some of them run on fuel), and the network infrastructure itself They were variables that influenced such unequal conditions to be experienced. A single network. In its statement, the CNMC proposes that the four giants of the Spanish territory put roaming plans at the service of the population in emergency cases. The experience of other countries shows that it is viable to incorporate roaming plans between operators in case of emergency. In this way, in areas where this was necessary due to the unavailability of service in an operator’s mobile network, the networks could be prepared to quickly enable the basic telecommunications services of the affected users through roaming in the networks of other operators. According to the regulator, this is an “ideal measure to strengthen resilience”, but it is not so easy to apply. Yes, but. What the CNMC proposes is a cross-roaming service between Telefónica, Vodafone and MásOrange, something that requires coordination and agreement between the three giants. The best example is Sweden where, after two years of preparation, any mobile phone can connect to any operator. Go deeper. In addition to this proposal, the CNMC requests the mandatory nature of the alert system HANDLE in those cars with DAB+ radio receivers (the evolution of FM radio). Although DAB+ works via antenna (like AM and FM radio), its signal is digitally encoded. The ASA system allows you to automatically activate a DAB+ radio connected to power, being able to quickly launch alerts. At the moment, there is a distance from proposal to fact.

Nuclear waste is a problem, so Germany is looking for the solution in a Jurassic rock in Switzerland

by

Nuclear energy is capable of generating clean electricity, continuously and in large quantities. A marvel except for two small details: the risk of a possible leak and what to do with its waste. The most widespread solution is bury them in a nuclear cemetery and wait. How much? Well, it depends, but it could be hundreds of thousands of years, until they are no longer dangerous. The million dollar question is where. An international research team led by Germany has started to drill a hole in a Swiss mountain to try to answer it. The project. Her name is DEBORAH (Deep borehole to resolve the Mont Terri Anticline Hydrogeology), stands for deep drilling to understand the hydrogeology of the Mont Terri anticline and is exactly what it does. Your goal? Document in great detail the layers that exist and their properties. There is some especially interesting material: Opalinus Clay. This deep experiment involves the German Geosciences Research Center GFZ and the German Federal Institute for Geosciences and Natural Resources (BGR), the Nuclear Waste Service (NWS) of the United Kingdom and Swiss researchers from the University of Bern. Why is it important. Because it can be the ideal rock to build a radioactive waste deposit. As details GFZSwitzerland has already made the decision, but Germany and the United Kingdom (the other parties to the project) have not yet. The key is what the analysis of the drilling says: details such as how much water it allows to filter, at what speed or where it will be key to making the decision. It is not trivial: a leak, no matter how slow and small, can contaminate aquifers. What’s special about it. The Opalinus is a clay rock dating back to the Middle Jurassic, with an estimated age of approximately 175 million years. Simply put, it is clay that has been compacted into rock. And it has a property that makes it a good candidate for nuclear storage: its very low permeability. Context. The study of Opalinus is not new by any means: GFZ’s on your radar for 30 years because, in addition to its very low permeability, it has properties such as its plasticity (under pressure, warps instead of breakingsomething convenient if it works as a radioactive deposit) or its ability to retain certain radionuclides. Switzerland has already chosen it, but it remains to be known how it behaves under the conditions that exist in much deeper areas, where, for example, temperature or pressure change noticeably. How they do it. In the Swiss canton of Jura, near the municipality of Saint-Ursanne, there is that Mont Terri. In its bowels there is an underground laboratory that is accessed through the security gallery of a highway tunnel, about 150 – 200 meters underground. A drilling platform works continuously there, advancing meter by meter, until reaching a depth of 800 meters. The drill uses a hollow crown that allows extracting intact rock columns, the sample that is later analyzed in the laboratory. Each advance works as a witness insofar as it reveals the age, the composition, the fractures and the differential quality: how it behaves with water. In addition, they use seismic and gravimetry techniques to obtain a complete x-ray of what is hundreds of meters deep. In Xataka | Ships have been damaging the oceans with noise for centuries.

The games of 2026 aim to be graphic marvels. NVIDIA is clear that the solution is in AI

by

The GDC, or Game Developers Conference, is a very special video game event. It is not focused on announcement of new titlesbut to holding presentations and roundtable talks between those who create video games. Lovers of the most technical issues in the industry consider it an unmissable event, and the one who does not skip an edition is NVIDIA. And in this GDC 2026 it has arrived with all his muscle and a clear idea. The future of gaming goes through artificial intelligence. DLSS 4.5, the umbrella. Leaving aside the current situation of the PC market due to the requirements of artificial intelligence and unprecedented crisis where we find ourselves, AI applied to video games is something that NVIDIA has been pushing for several generations. A lot has happened since the RTX 2000 and the arrival of ray tracing in real time along with a solution to make performance more sustained: DLSS. Deep Learning Super Sampling is a scaling tool that allows the GPU to render the game at a low resolution and then scale it to the native resolution of our monitor. This allows for improved frame rates in performance while maintaining image quality. With the passing of generations, DLSS has been evolving until it becomes a complete neural rendering suite that involves several technologies. It is no longer just scaling through deep learning, but another series of techniques to improve both image and performance. For its main work, DLSS 4.5 presents greater understanding of the scene, improving both image quality and performance at higher resolutions. But he has more things up his sleeve. Frame Generation. One of them, perhaps the most notable, is the enhanced frame generation mode. If in the previous generation DLSS could multiply the frames per second of the image by up to four (through this deep learning, four frames were “invented” for each native one provided by the GPU), with DLSS 4.5 the figure increases to 6x. This is crucial to maintain fluidity in games with extreme graphical loads if we want to play at 4K. Because at 1,440p, the power of the GPU is more than enough, but to play in 4K with all the current effects activated, generating frames seems key if we want to take advantage of the high refresh rates of the monitors. According to NVIDIA data, the step from 4x to 6x increases performance in titles with path tracing in 4K by up to 35% on RTX 50 GPUs. It uses Reflex technology, also from NVIDIA, so that latency is minimal, and the scenario is most curious because we can be playing a game in which most of the frames are reconstructed, and not native, without us realizing the latency. Multi Frame Gen, the “magic”. Within that frames per second multiplier, there is a very interesting technology: DLSS 4.5 Dynamic Multi Frame Gen. Its name is quite self-explanatory and,. Basically, it consists of an algorithm that establishes the best frame multiplier for each moment depending on the image, the performance of the GPU and even whether we have vertical synchronization activated or not. It is an automatic change that changes all the time between 2x and 6x (passing through intermediate multipliers) with the objective of always maintaining the highest possible frame rate per second, but without spending resources foolishly. That is to say: if we have a 120 Hz monitor, the GPU changes the multiplier depending on the situation to always try to guarantee those 120 FPS, but without wasting resources. If in a game we are in a phase with low graphic load (an interior, for example), only a 4x multiplier may be necessary. If we go outside, maybe we need that 6x push, and what the system does is change automatically. The next time we are inside it will go back to 4x and so on constantly. The explanation is simple: the aim is to make the experience as consistent as possible, but without generating frames foolishly to prioritize native frames over those generated by the AI. “New” word: path tracing. And all these technologies to give life to games that will soon begin to consume more and more of the PC’s native resources. Because if ray tracing is already demanding, we are going to have to get used to a new term: path tracing. It’s not new, but it’s basically a more complete form of ray tracing that attempts to even more realistically simulate how light impacts game geometry. Ray tracing can be applied to everything (shadows, reflections or global illumination) or separately, but path tracing is a unified solution. In short: it is like applying all possible ray tracing, but at the same time. This consumes a lot of resources, something we can see in games like ‘Cyberpunk 2077‘ either ‘Resident Evil Requiem‘, and is the reason for DLSS 4.5 rendering techniques and 6x frame generation. The games are ready. In the end, it’s about AI allowing you to achieve performance that the GPU, on its own, might not achieve. In top-of-the-range graphics like RTX 5080 or RTX 5090 We may want to ‘pull’ the native resources, but with others like the 5070 or the 5060, these AI ‘helps’ allow us to further stretch the visual quality of a game while maintaining good performance. And all these tools together will be necessary if we take into account what is to come. Because we have already mentioned some games, but over the next few months others will arrive like ‘007 First Light‘, ‘Resonant Control‘, ‘Star Wars Galactic Racer‘ either ‘Directive 8020‘ that promise to be visual wonders and that will integrate these technologies.

If the controversy is that AI steals works in its training, the European Union has the solution: license them

by

A few weeks ago the Washington Post published this image of the “Panama Project”: It is a warehouse with hundreds of thousands of books waiting their turn to be scanned and destroyed in the process. It is part of an internal program Anthropic to train its AI and the result of tens of millions of dollars in purchases to digitize all those works without permission from their authors. They are not the only ones who “they borrow” copyrighted content to train their artificial intelligences and the European Union is clear about something: stop stealing protected content and properly license works to train AI. And AI companies defend themselves by saying that no one is going to think about small companies. Europe is clear: if you want to train AI, pay the author It is curious how the entertainment industry and the regulation of countries shook hands at the beginning of the 2000s with those ads of “you wouldn’t steal a purse. You wouldn’t steal a car. Don’t steal a movie.” They portrayed copying a CD or downloading a movie as if you were breaking into the Pentagon’s systems. Years later, that same industry turns a deaf ear given what big technology companies are doing to train AI. The Washington Post document states that others such as Meta, Google and OpenAI They had also participated in the race to obtain data in bulk for your models. There are kicking examples, like the 81.7 TB of copyrighted books that you have downloaded Meta or that OpenAI will use animation from all the studios to train its AI (earning reproaches by Ghigli and more Japanese studies and complaining that Deepseek has looted ChatGPT). Given the context, it is time to say that the European Parliament has grown tired of this and has one of the things he is best at: legislating. In this case, it makes perfect sense for Europe to take this measure, and the agency issued a report non-binding law that urges the European Commission to develop rules that set minimum standards for these AI companies. “Generative AI should not operate outside the rule of law” Basically, if they use protected content for their training, they must license it and also compensate the authors. with the title “Protecting creative work with copyright in the age of AI”the European Parliament demands a series of measures apart from licensing the works. They are the following: Calls for the transparent and remunerated use of protected content to train generative AI. AI vendors are expected to recognize and pay for the copyrighted work they used to train their systems. Measures so that owners of works with rights can exclude their protected work from training. The reason that they argue MEPs is that “generative AI should not operate outside the rule of law. If copyrighted works are used to train artificial intelligence systems, creators have the right to transparency, legal certainty and fair compensation.” The European Group of Societies of Authors and Composers, or GESAC, points in the same direction. In statements to EuronewsAdriana Moscoso del Prado, general manager of GESAC; assures that “this vote adds to the growing recognition at the EU level of what is at stake. Innovation, equity and cultural sovereignty must go hand in hand.” AI companies fight back From the CCIA, the Computer and Communications Industry Association, it was noted that this is not a measure to protect artists, but rather “a compliance tax.” That is, something that must be fulfilled no matter what and that goes against progress. The group argued that such a measure would not go against large companies, but against small ones. They say that many will have difficulty negotiating complex licensing agreements with major publishers, “holding back Europe’s digital competitiveness on the global stage” and stating that what they would need to do is improve existing laws in the European Union, including the AI ​​Law and the Copyright Directive. In any case, there is nothing on the table at the moment. As we say, it is a self-initiative report by Parliament and is not binding. The Commission can now consider whether to do so or not, but it makes one thing clear: Parliament’s position on any future AI measures by the Commission. The problem is that generative AI has already plundered millions of copyrighted works on which it can build its next interactions. The software has tons of information to pivot on and can evolve in other areas, like stopping hallucinating, for example. And it is another example of the two speeds of this matter: the technological ones taking the first steps and the legislators behind them seeing what can be done when the act they want to legislate on was already carried out years ago.
