Month: March 2026

I have calculated how much I will spend on gasoline this Easter. I’m already looking for an electric car

by

Tomorrow, March 28, will mark one month since the United States and Israel attacked Iran in an offensive that appears to be stalling. Four weeks since the Strait of Hormuz was effectively closed, since the price of oil skyrocketed and gasoline prices skyrocketed. Four weeks paying more for our deposits. Four weeks looking at electric cars with different eyes. Tied to fuel. The price of gasoline and diesel has fallen significantly since the Government applied the discount on VAT on hydrocarbons. The market, which was beginning to reach two euros/liter, has relaxed in the case of gasoline (1,562 euros/liter on average), according to dieselgasolina.combut it is still very high in the case of diesel, which remains at 1,773 euros/liter. This gap between diesel and gasoline is making let’s live an unprecedented situation. Already with the war in Ukraine we saw the price of diesel skyrocket. Now, with Russia already out of the market (at least the legal one) and with a new tension in the supply chain, Europe is witnessing an increase in diesel prices for having gotten rid of its refineries over the years. A considerable saving. Taking prices in Spain as a reference, the savings in the cost of using an electric car were already high in recent years. But this has skyrocketed in the last month. Spain continues to be dependent on diesel for an aging fleet where diesel is used by 57.1% of the total volume of cars, according to Anfac. although new cars sold with this technology are very few. And in Europe the x-ray is very similar. This has made many look at the electric car with different eyes. How we tell you our calculator and the professionals themselves explainthe more kilometers traveled with an electric car, the cheaper its cost of use. Or, simply, the greater the gap that exists with gasoline. Let’s give an example, with diesel at 1.773 euros/liter, traveling 100 kilometers with a car that consumes five liters of fuel costs 8.86 euros. In the case of gasoline, if the car consumes seven liters on average, the cost to travel 100 kilometers is 10.93 euros refueling at 1.562 euros/liter. With an electric car that consumes 20 kWh/100 km on the road, the cost is the following: Domestic rate (10 cents/kWh): 2 euros/100 km Direct current recharging up to 50 kW (20 cents/kWh): 4 euros/100 km Direct current recharging up to 150 kW (30-45 cents/kWh): 6-9/100 km Direct current recharging above 150 kW (60 cents/kWh): 12 euros/100 km Winner? Yes, especially the slower we reload. And the comparisons between a combustion car and an electric one are somewhat complicated since the consumption of the car on the road (quite variable between electric cars) and the price of the chargers come into play. Below we will leave a practical example but first we will make some details clear: The consumption of an electric car on the road has important differences. A Tesla Model 3, perhaps the most efficient car at the moment, consumes about 16 kWh/100 km at sustained rates of 120 km/h. A “gastón” car can go at 24 kWh/100 km. That, with high rates, means recharges of up to four euros more per 100 kilometers The real savings of an electric car are in slow recharges, especially domestic ones. Here, rates vary greatly. There are flat rates of 15 cents/kWh but those who have license plates and a favorable environment can charge at 0 cents/kWh for a good part of the year. In our case, we are going to assume 10 cents/kWh. On a trip like Easter, it is very likely that we will stop to sightsee in a city or to eat. At these stops, slow or direct current charging can be done but at low power, below 50 kW. Just as service stations have loyalty cards and programs, electric car users can also take advantage of subscription rates to save money. We will leave them aside because the possibilities in both cases are very wide. Our example. To understand whether or not we save money, let’s assume that this Easter we add a trip of 2,000 kilometers. In it, we will leave with a full battery, as a typical electric car user would. Our electric car has a range of 400 kilometers. The round trip will take us 1,200 kilometers and we will do another 800 kilometers moving from one place to another, getting to know new places. Let’s assume that the car’s consumption is 20 kWh/100 kilometers and that the battery has a size of 80 kWh. Thus, we are going to assume the following recharges: We leave home with 100% (80 kWh and 400 km) and we stop when we have 10% battery left (8 kWh and 40 km) We fill the battery with a high-power charger up to 80% (we have recharged 56 kWh and have 320 km available) and we arrive at the destination with 80 km left in the battery (20%) At the destination we charge the battery to 100% to move with a 50 kWh charger. We have a second recharge at destination. We are going to do 800 kilometers of tourism, that is two full batteries which is equivalent to the first full recharge already mentioned and a second to have another 400 kilometers ready. On our return we will repeat the move: we will charge in our holiday area (third recharge at destination) with a 50 kW charger up to 100%, we will repeat the fast charging on the road at more than 150 kW and we will fill the battery at home to 100% to check the real cost. Here we will arrive with 20% battery. The expense. Taking all this data, we have the following results: First recharge on the way up to 80% (56 kWh at 0.60 euros/kWh): 33.60 euros First recharge at destination up to 100% (72 kWh at 0.20 euros/kWh): 14.40 euros Second recharge at destination up to 100% (80 kWh at 0.20 euros/kWh): … Read more

the bravery with which he fought until the end

by

That of the Titanic is a story with many dates. There is that of the firm that made its construction possible, in July 1908, that of its launching, at the end of May 1911, and that of the beginning of its maiden voyage, on April 10, 1912. The most famous of all is, however, the most tragic and the one that has turned it into a legend: April 14, 1912. That day, minutes before midnight, the brand new White Star Line ship collided with an iceberg off the coast of Newfoundland. The impact was so brutal that it took only a few hours for the ship to sink. Now, more than a century later, the Titanic writes another new chapter. One that allows us to understand the courage with which his crew acted. What has happened? What science has given us a new perspective and fascinating of the Titanic. Although the remains of the liner rest a few 3,800 meters deep, in the icy waters of the Atlantic, a group of researchers has carried out an exhaustive 3D mapping of the wreck with which they have been able to generate a ‘digital twin’. A unique copy to date. The work was carried out by Magellan Ltd during the summer of 2022 with the help of remotely controlled submersibles. For more than 200 hours a team of experts analyzed the pediment from top to bottom and produced more than 700,000 images taken from different angles. Thanks to them we have a 3D replica that has already been used for the documentary ‘Titanic: the digital resurrection’from National Geographic and Atlantic Productions and released last year. Why is it important? Firstly because it offers us a unique vision of the wreck, which in turn opens a world of possibilities for researchers. in words by Rebecca Morelle and Alison Francis of the BBC, the scan allows us to observe the liner “as if the water” around it had been drained. It may seem like a simple anecdote, but despite the enormous attention it has generated and the number of studies dedicated to the Titanic over recent years, all the unknowns surrounding its sinking have not yet been resolved. “There are still questions, basic questions that need answers,” recognize BBC News Parks Stephenson, an expert on the ship’s history. The 3-D model is important because it allows researchers to go one step further, abandoning the realm of speculation and theories to rely on evidence, something that until now was complicated by the environment in which the wreck rests. Its depth, temperature and lack of light have made it very difficult for researchers, who have had to settle for fragmented images. And what does it show us? Of everything. From the structure of the ship, split in two during the sinking, to much more detailed details. For example, the number of series of one of the propellers, the damage to the deck where the lifeboats traveled or even the debris scattered around them. “Every square centimeter has to be mapped, even the least interesting parts. For example, in the debris field you have to map the mud. It is necessary to fill the gaps between all those objects,” confessed in 2023 to the BBC Gerhard Seiffert, a member of the expedition. Has it been of any use? Yes. Thanks to all the material collected and computer simulations, experts have confirmed that what probably precipitated the sinking were the perforations that can still be seen in the hull. It is just one of the many clues collected by researchers and which, although they may seem minor, complete the chronicle of the wreck. For example, scanning a porthole shattered during the collision confirms to historians that ice entered some cabins. Another conclusion relevant, achieved thanks to computational models, is that the impact with the iceberg left a series of perforations that extended in a straight line along the hull. Can we go further? Again the answer is ‘yes’. The scan has allowed researchers to ‘sneak’ inside the ship itself, revealing part of the mysteries of the internal chronicle of the sinking. One of the most fascinating chapters is the boiler room. The experts focused specifically on one of its installations, located at the rear of the stern section, right where the ship broke up when submerged, which has made it easier to scan. Again it might seem like a curiosity, but it is not: experts have found evidence that part of the boilers were still working when they were submerged in the icy waters of the Atlantic. And that is important. He tells us a story of sacrifice and bravery about the last hours of the Titanic. What story? During their work, investigators found two clues. One is what we mentioned before: that at least part of the boilers never stopped working, something that can be deduced from their condition. The other was left by a valve located on the deck of the aft section. The 3-D scan reveals that it is open, suggesting that the system that generated electricity on the ship probably remained operational during the most tragic moments. Does that matter? A lot. The activity of the boilers allowed them to continue generating electricity and this, in turn, made it possible for the crew members to have light when they were looking for a way to save their lives. If we take into account that the impact with the iceberg occurred in the middle of the night and that the Titanic sank at dawn, it is not a minor detail. More lighting probably translated into greater chances that passengers could get into boats and survive. Was it that important? “They kept the lights and electricity running until the end to give the crew time to launch lifeboats safely with some light and not in complete darkness,” Stephenson reflects.. “They managed to contain the chaos for as long as possible. And all of that was represented in that steam valve that was in the stern.” … Read more

What is the difference between Dolby Vision, HDR10+ and HLG in streaming apps?

by

It’s time to renew the television and you go to a store to consider different models, but once you get to work comparing the specifications you find yourself in an alphabet soup: HDR10, HDR10+, Dolby Vision or simply HDR. We already made it clear to you that all these technologies are aimed at offering better image quality, but they do not work the same nor do they achieve the same result. Therefore, today we are going to review what the differences are so that you can make the right choice for the next television. The price could vary. We earn commission from these links What is HDR The High Dynamic Range (HDR) is an imaging technology that aims to increase the difference between dark and light areas. Keep in mind that 4K resolution adds a higher number of pixels, while HDR makes those pixels better by offering much more vivid colors and deeper blacks. HDR10, the standard format HDR10 is essentially “normal” HDR, since it is the standard that all televisions and all platforms usually use. The reason is that it is open language; Brands do not have to pay for it and usually include it in their televisions. How does it work? Movies, for example, usually have predefined brightness and color levels, so once we play it they will be applied throughout it. The settings will be the same throughout the movie, whether all scenes are darker or lighter, and that is where the problem is. The biggest drawback of the HDR10 format is that does not apply scene to scenebut throughout the entire film equally. This means that sometimes the lightest or darkest scenes do not look quite good, so in the end some detail will be lost in these types of scenes. Dolby Vision, scene-by-scene configuration Dolby Vision is a technology from Dolby Laboratories, so in order to include it in their televisions, brands have to pay for it. This makes many brands decide not to use them and We have the best example in Samsungwhich prefers to include other open HDR formats. The great usefulness of Dolby Vision is that, unlike HDR10, it is capable of adjusting the brightness and colors scene by scene, adapting to certain situations in which there is high contrast so that the entire movie looks good. Perhaps you have seen the name of this technology on platforms like Netflix, and it is because it is the one that is usually found in high-quality content. But here’s something you should keep in mind: it doesn’t matter if your television is compatible with this format, if the platform decides that it will only include it in the most expensive subscription levels, and you have the cheapest one, you won’t be able to take advantage of it. Keep this in mind when choosing a television, Are you going to take advantage of this technology?. HDR10+, almost free Dolby Vision TV showing content without HDR10+ (left) and with HDR10+ (right). Why doesn’t Samsung include Dolby Vision in its televisions? The fact that, along with brands like Amazon and Panasonic, it decided to launch its own format has a lot to do with it. HDR10+ is the free technology that directly competes with the Dolby Vision that we have now, and is currently available on many televisions, especially mid-range and high-end. However, despite the fact that HDR10+ is currently found in a good assortment of televisions, the truth is that supported content is very limited; even more than Dolby Vision. Keep in mind that if you buy a Samsung, Prime Video will be your best ally because it is one of the few that uses HDR10+. Although HDR10+ tries to compete head-to-head with Dolby Vision, the latter plays in another league. The reality is that there are still no home televisions capable of squeezing out their full potential; While current screens reach brightnesses of 2,000 nits, Dolby Vision is designed to reach levels of up to 10,000 nits and much higher color richness. It is basically a future-proof technology. On the other hand, with HDR10+ we are faced with a format that, despite having a similar name, is different from HDR10 because allows you to optimize lighting scene by scene throughout the entire moviethus offering a much better result. HLG, the format for live broadcasting We have Hybrid Log-Gamma (HLG) on practically all televisions, and this is because it is the format that is used in live content (also delayed) instead of streaming. In other words: it is the one used when you watch the news or a football match. HLG is intended for use on both HDR-compatible televisions and SDR models (older TVs), since it is a format that is broadcast in content en masse. The quality does not come close to what we find in Dolby Vision technology, but it is efficient for live broadcasting. The good and the bad of both options, face to face HDR10 Dolby Vision HDR10+ HLG THE GOOD 🟢 It is present in practically all televisions. It offers the best quality by having a lighting configuration that varies scene by scene. It is present on many televisions and offers an experience close to Dolby Vision. It offers better quality in live or delayed broadcasts. THE BAD 🔴 It maintains the same lighting settings throughout the movie, offering poorer quality in scenes with high contrast. It is not present on all TVs and sometimes the platforms reserve it for the most expensive subscriptions. There is not much supported content. It is not compatible with streaming content. Ideal for: People looking for a very economical television. Enjoy the best experience watching a movie or series and playing video games. Watch movies in better quality than HDR10 offers. Watch live or delayed broadcasts with better quality. What TV should I buy then? At this point, you may be thinking which one is worth it. If you choose a TV, you should pay attention to the HDR or Dolby format, especially depending … Read more

drones attacking North Dakota nuclear bases

by

The United States’ nuclear strategy has long been based on the so-called “triad”a system that combines submarines, land-based missiles and bombers to ensure responsiveness even in the worst possible scenario. The model, designed in the middle of the Cold War, assumed that the continental territory was practically inaccessible to direct threats, which allowed the defense to be concentrated abroad and not so much on protecting each installation within the country. Until the drones have arrived. An unprecedented attack on the nuclear heart. What happened, according to what they said several analystsis that while the United States bombs Iran in its large-scale operation, something completely unexpected is happening within its own territory. Drone waves They have flown over key bases linked to the US nuclear arsenal. Apparently, these were not isolated incidents or improvised devices. They were coordinated incursions, repeated attacks for days that have forced stop critical operations and activate emergency protocols. For the first time, in the middle of a war, strategic installations on American soil were directly affected by a persistent aerial threat. Barksdale, the critical point. The most striking case occurred in the Barksdale Air Force Baseone of the pillars of the United States nuclear system. Strategic bombers operate there and long-range missiles are stored, making the facility a key node within the country’s deterrence capacity. For several days, the swarms of drones They have flown over the base in organized waves, forcing interrupt bomber sorties who participated in the attacks on Iran. The scene, more typical of a movie, has been difficult to ignore: while the B-52s prepared to project force thousands of kilometers, the airspace above their own runways was committed. Advanced drones. The most worrying thing was not only the presence of these drones, but its technological level. They counted on ABCNews that the devices showed a remarkable resistance to electronic interference, used variable entry and exit routes and operated in dispersed patterns that made them difficult to track. In fact, countermeasures designed to neutralize these types of threats they didn’t work as expected. This suggests that these are not tailored trading systems, but rather platforms much more sophisticatedcapable of operating with partial or total autonomy and collecting information in highly protected environments. More than a physical threat. There is no doubt, these drones not only represent a risk for Washington due to their potential attack capacity, but also due to the type of information that they can get. When flying over critical facilities, they can map electronic emissionsidentify operating patterns and photograph sensitive infrastructure. In other words, they can build a detailed portrait of how a strategic base works from within. And this opens the door to much more precise and effective future attacks, as it turns each raid into a highly valuable reconnaissance mission. Structural vulnerability in national territory. They remembered on TWZ that the raids are not limited to a single point or a specific moment. They have registered similar episodes at other key bases, including strategic bomber-related facilities and advanced technology development centers. In many cases, these infrastructures they lack systems adequate air defense systems against drones, which forces us to rely on improvised or developing solutions. What’s more, even with new tools deployed, the ability to neutralize these threats remains limited and uneven. The strategic paradox. The contrast is more than evident. The United States maintains an unprecedented global military capability and can project force virtually anywhere on the planet. However, at the same time, shows difficulties to fully protect sour own facilities against relatively small, but technologically advanced threats. This paradox reveals a mismatch that already we saw in Ukraine and now in Iranone between traditional defense architecture and new forms of warfare, where cheap and difficult to detect systems can generate disproportionate effects. Paradigm shift underway. In short, what happened, for unpublishedpoints to a deeper transformation in the way military security is understood. Not even the bases, silos and strategic infrastructures of a superpower like the United States can considered safe spaces by the mere fact of being in national territory. Because the combination of advanced drones, sensors and electronic warfare is taking the conflict directly to the heart of powers. And that implies, or opens the disturbing possibility, that the next great battle will not only be fought abroad, but also in the ability to protect what until now was taken for granted.

In the middle of the war, Israel’s underground parking lots have begun to fill with something: tents

by

On the fourth floor of the underground parking lot of the Dizengoff Centerone of the most popular shopping centers in Tel Aviv, the difficult thing these days is seeing cars. There are also not many motorcycles, vans or any other type of vehicle. What has occupied the squares painted on the ground for weeks are dozens of tents, the ‘home’ improvised by Israelis looking for a place to protect themselves from the attacks with which Iran has responded to ‘Operation Epic Fury’ that on February 28 ended the life of its leader, Ali Khamenei. While on the surface the sirens sound warning of the arrival of missiles, there, on the -4 floor, life goes on among removable tents. “Look where I am”. With that phrase I started a few days ago tiktoker Andrea Bisso (@Latinaenisrael96) a video in which it shows the parking lot of a shopping center in Israel. The curious thing is that as you walk through its corridors you don’t see cars or people with shopping carts, but rather tents, an improvised table on pallets where food is distributed, handwritten posters hanging from the columns, clothes hanging from cables… The landscape that marks the daily life of the dozens of families who take refuge there. “People are living here now, in times of war. This is where they have moved. It’s incredible how people started to live in a parking lot. These are people who have small children, can’t run to a shelter, don’t have one nearby or are elderly who can’t go down the stairs… They prefer to live here,” relates Andrea as she walks through the parking lot. “Alternate reality”. The tiktoker is not the only one that has shown how the war has transformed some unexpected places in Israel. A few days ago Zeb Stub also did it on an extensive report for The Times of Israel in which it affects the same idea. In fact, he talks about the “alternative reality” that has been created on the -4th floor of the Dizengoff Center parking lot, where “a city” basically made up of dozens of tents has been deployed. Curiously, life activates beneath the surface while it decays in commercial areas. Stub explains for example that in the Azrieli Centeralso in Tel Aviv, some businesses estimate that activity has fallen by 20% or even 50% in recent weeks. “Many people come simply to get out of the house,” they say from a shoe store. “The normal thing before Passover is that people come to buy new clothes, but this year they are not thinking about that.” Life goes on underground. Gal, a teacher who teaches remotely, explained to the Israeli newspaper that she decided to move to the Dixengoff shelter last week among other reasons because she had to constantly interrupt her work in her apartment. “I teach online classes and having to stop every time the siren sounds is making my work more complicated,” recognize the woman In the shelter you don’t just see people eating, sleeping, working or simply hanging out. a chronicle from the Associated Press (AP) talks about much more casual scenes, such as a bride posing with her family for a wedding photo session or young people dressed up for celebrate the holiday Purim Jewish… There are also spaces for attend to medical emergencieslike the improvised one in a parking lot under the Sheba Medical Center, in Ramant Gan. Are there no conventional shelters? Yes. Israel has public shelters. It is also not unusual to find private spaces designed precisely so that people can take shelter during emergencies. When the alarms sound, people barricade themselves in them, usually for fifteen minutes, half an hour… however long the alert lasts from when the sirens sound. However, there are those who, for one reason or another, choose to put their belongings in a suitcase and temporarily settle in spaces where they feel safer than in their homes, such as parking lots. The Dizengoff Center is an example, but there is more. Under the Tel Aviv bus station there are dozens of families, especially immigrants, who have settled in tents. Crossover attacks. Noah Efron, from the Tel Aviv-Jaffa municipal council, claimed these days that the underground shelters in Tel Aviv are designed to house families at times like the current one, when the Middle East is convulsed by the offensive launched by Israel itself and the US on Iran. Over the last few weeks, cities like Tel Aviv have received attacks of the Islamist regime, damaging buildings and causing injuries and even fatalities. Israel is not the only one living under the threat of missiles. His army has also been hitting Iran and Lebanon for weeks. In fact, in cities like Tehran or Kfar Rumman there are a significant balance of wounded and dead.

sending personalized Ferraris to millionaires in the Middle East

by

When the conflict between the United States, Israel and Iranthe Strait of Hormuz was closed to commercial traffic and the skies of the Persian Gulf They became a high-risk area. Freighters transporting luxury cars to Dubai, Riyadh or Doha encountered a Strait of Hormuz blocked and no alternative route plan. Any customer in that situation has little room for maneuver other than resigning themselves to waiting for their shipment like someone waiting for an Amazon courier, but a type of client who does not resign easily: he who has enough money to open your own delivery route. While hundreds of Lamborghinis, Bentleys and Ferraris were immobilized in intermediate ports due to the maritime blockade, their future owners found the most million-dollar solution possible: paying for “first class” flights so that their supercars They will arrive by plane. Cars blocked in the middle of the conflict. When the Strait of Hormuz was closed to commercial traffic, large cargo ships were unable to reach their destinations in Persian Gulf ports. One of the most striking cases was the one documented Reuters of a shipment with more than 500 cars that were blocked at sea. 50 of those cars They were luxury models of brands such as Rolls-Royce, Lamborghini and Ferrari and had to be provisionally unloaded at the port of Hambantota (Sri Lanka) pending resolution of their fate. The same problem affected Porsche and Audi, whose managers in the Volkswagen group they warned that the war would directly hit their sales in the region. OK to what was published by BloombergFerrari suspended shipments to the Persian Gulf for weeks. A wall between brands and millionaires. Faced with the blockade, each manufacturer adopted a different strategy, although they could not prevent some of the luxury cars that were already on the route from being trapped in nearby ports. Bentley chose to exhaust the inventory that dealers in the region already had to meet pre-conflict orders, avoiding shipments of new units. Ferrari, on the other hand, opted for a combination of longer and more complex alternative routes: more than 4,000 luxury vehicles bound for Dubai had to be diverted to Lamu Island port as an alternative entry point. Meanwhile, some millionaires impatient to drive the cars for which they have been waiting for no less than two years, did not want to wait a single minute longer and paid the extra cost of shipping with air transport to receive their cars as soon as possible. A decision that turned out to be more expensive than expected. The price of millionaire impatience. Air transport was already an import route that existed before the blockade of the Strait of Hormuz, but it tripled the cost of shipping. With the war blocking the only access route, that difference shot up to five times more. The average cost of transporting a kilogram of air cargo from Europe to the Middle East has increased by two-thirds since the start of the conflict, reaching $2.96 per kilogram of cargo. as he collected he Financial Times. Some routes recorded increases of up to 100% in rates, with an additional fuel surcharge of between 0.3 and 0.4 euros per kilo transported. Ian Arroyo, director of strategy at Freightos, a logistics information service, pointed out that there were only two options for assuming this price increase: “It all depends on whether manufacturers are reducing their own profit margin due to their relationship with the customer, or if the customer has offered to pay for the transportation on their own.” What is clear is that the final bill for the car was going to rise considerably. Money was not going to be a problem in this case. Ferrari does not lose a single order. In statements to Gulf NewsGiorgio Turri, Ferrari’s general director for the Middle East, assured that the brand had managed to overcome logistics problems without canceling any orders in the area. “We are not experiencing cancellations. (A Ferrari) is not a need, it is a dream. You don’t make decisions based on the mood of the day. Dreams are never a short-term decision.” The data proves him right. Between 30 and 40% of the Italian brand’s new supercar deliveries in the region go to customers who have never owned a Ferrari before. The Middle East is not the largest market in the world in unit volume, but it is one of the most profitable for the “Il Cavallino” brand. Customization and accessories account for a fifth of Ferrari’s revenue, and the region’s wealthy customers don’t just buy the car: they turn it into a unique piece doubling the car bill with customizations . To understand the dimension of the business that was at stake, it is enough to know a fact that Turri pointed out, “our clients in the Middle East are between five and seven years old. younger than the world average.” That for Ferrari is not a simple anecdote, it is decades of guaranteed sales if customers are satisfied, whether there is war or not.

The IOC has a new method to exclude trans athletes from the Olympic Games. The problem is that biology doesn’t work like that.

by

At the end of March, the International Olympic Committee announced undoubtedly one of the most controversial decisions in its recent history: starting with the 2028 Los Angeles Olympic Games, no transgender athlete will be able to compete in the women’s category. But beyond the social and political debate that can be generated, we must also focus on the method chosen to determine this exclusion: a simple genetic analysis where a single gene is searched. And this is something highly discussed among science. His discoverer. The gene in question, which will be analyzed in athletes who want to participate in the female category, will be SRYwhich is nothing more than the “Sex Determining Region Y”. A gene that was discovered in 1990 by molecular biologist Andrew Sinclair and who pointed out that its presence is a determining factor in male sexual development. It is, literally, the scientific father of the test that the IOC has chosen to integrate into its Olympic requirements. But the thing is that he himself is against using it for this. Your disagreement. This decision is not a big news, since if we look back, the body that governs world athletics, World Athletics, adopted this same test in September 2025 to participate in their competitions. Here is Sinclair himself He did not hesitate to publish an opinion article where he made it clear that the result is not definitive, since the only thing the analysis can say is whether the gene is present or not. Because. In this way, it must be detailed that being positive in SRY does not give us information about whether it is working to form a testicle, if it stimulates the production of testosterone or even if it expresses the necessary receptors so that testosterone can be used. Put another way: knowing that an athlete has the SRY gene does not tell you anything conclusive about her physiology, her hormonal levels or, by extension, about her supposed competitive advantages from having testosterone. The biology of sexual development is infinitely more complex than the presence or absence of a genetic marker, which will now mark the ‘everything’ before the IOC. There is more evidence. This researcher is not the only one who opposes this decision, since at the beginning of March it was published an article signed by 34 academics to respond to the decision of World Athletics. Here they pointed to the same thing: we are facing a test that reduces everything to a single gene when biology is much more complex. And biological sex is the result of a very complex interaction of human genetics, hormones, receptors, tissues… Furthermore, the IOC’s argument suggests that this test protects against competitive equity, but for academics, they point out that there is no solid scientific evidence to demonstrate that the presence of the SRY gene is directly related to having a greater sporting advantage. It’s not something new. Although we now see a big scandal in the sports world over this decision, the reality is that if we look at the newspaper archive, something similar was already being done in the 90s. 30 years ago The IOC decided to require women to verify their sex through chromosomal testing and also by determining the SRY gene. But finally the tests were withdrawn due to technical limitations, the absence of medical evidence and also because of the legal problems it could have. A Spanish case. Due to these tests, the Spanish athlete María José Martínez Patiño was disqualified in 1985 after testing positive in the chromosome test despite not having any physiological advantage over her peers. In this way, her career was practically doomed, but she was able to recover it thanks to the help of a geneticist who was able to document her case with scientific evidence that showed that it was not giving her an advantage over the rest of her competitors. The debate. If the basis for requiring genetic testing is to protect competitive fairness, we must ask what science says about the real advantages of transgender athletes. And at this point much less is known than the general population believes. One of the most important studies It was made in 2015 by a transgender researcher who analyzed the running times of eight athletes before and after their transition. In this case, the brands slowed down and their relative performance compared to runners of the same sex remained quite stable. An IOC study. Published in 2024 and partially financed by the committee itself, produced results that do not fit with the discourse we keep hearing: transgender women showed worse results than cisgender women in lower body strength and lung function. But logically it does not mean that there cannot be residual advantages in certain sports, which is something that to this day remains a question that needs an answer. And now what? We are undoubtedly facing a dispute about which tools are valid to solve a genuinely complex problem. Right now, science suggests that the SRY gene test is not the best tool, but because it does not give us a complete answer, since the SRY gene may be present and the body may not respond to testosterone. But this is something that today must continue to be investigated to obtain evidence that can guarantee this equity, but always with a scientific basis behind it.

What it is, what courses with official certification it offers and what free materials you can access

by

Let’s tell you what it is and what it offers OpenAI Academya web portal for the creators of ChatGPT with many free resources to help you learn how to use the artificial intelligence. It has practical tools and resources for users of all profiles, so you can learn how to use AI effectively and responsibly. Just as Anthropic has a series of free courses for ClaudeOpenAI opts for a different format. They are not courses in themselves, but rather a content and community platform including videos, articles, guides and live events. Although if you are looking for courses, we will also tell you about the two created by OpenAI. What is OpenAI Academy OpenAI Academy is a digital platform created by OpenAI, the company that created ChatGPT and one of those leading the artificial intelligence revolution for consumers. In it they centralize training resourcesto improve AI knowledge. The intention of this platform is to try help all types of users with various types of profiles. In it you will find content from people without any knowledge who want to take their first steps in AI to other types of professionals who want help to optimize their work in a specific sector using AI. Therefore, it is used to learn but also to specialize with the use of AI in certain areas. They do all this with a combination of online events, workshops, and other digital content. The idea is to be able to go from the fundamentals of AI literacy to its advanced integration when you are a developer. The platform is completely freealthough it will require you to register to access some of its content. Unlike other platforms such as Anthropic’s training platform, it is not a place for courses, but instead combines online resources thematic communities and all kinds of training tools. What OpenAI Academy offers The OpenAI platform offers various types of content. First of all, you have online or in-person training eventswhich are talks scheduled for a specific day or time. These talks are given by specialist educators, and anyone who wants can sign up to attend. And then we have a contents section, where you will find videos, resources, blog posts and external content. These are all resources aimed at helping users learn and better understand how to use artificial intelligence in different areas. All of these contents are served for different types of people. You’ll be able to find things for basic users like educators, OT workers, government or non-profit organizations, small businesses, students, healthcare workers, administrators and more. You will also find publications designed to teach you or suggest you Custom GPTs, prompt packs, advanced features and more. In short, all the resources to master ChatGPT to the fullest, categorized by tags and their type of content. And finally, you will also find an open communities section aimed at different types of users. These communities are like specific forums where you will also find content aimed at them and you can interact with other users. The only drawback you are going to encounter is that all contents are only in English. Therefore, if you are a Spanish-speaking user who does not master this language, you will not be able to enjoy them too much. They plan to expand the academy to other languages, but at the moment there are no specific dates. Courses with official certification Lastly, OpenAI also has two own courses with official certification. The only problem is that the courses are not within this platform. Instead, one of them is taught by ChatGPT for some users and the other is on a third-party platform. AI Foundations: A certification course for workers in any sector or industry. Not yet available to all usersbut only for certain people, but when it is, it will be taught directly within ChatGPT with the chatbot itself acting as the teacher. ChatGPT Foundations for Teachers: Course aimed at primary and secondary education teachers, to teach them the fundamentals of ChatGPT and to be able to customize it and use it in their work. It’s on Courseraand will soon be integrated into ChatGPT for Teachers.

Satellite images have revealed the location of Russia’s largest warship, and that means Ukraine can see it too

by

During the Second World War there was a announcement to sailors of future conflicts: some of the largest ships ever built were destroyed without having barely entered combat, becoming symbols of how vulnerable even the most advanced weaponry can be. Decades later, with the advent of commercial satellites and precision weapons, that exposure is even greater. Few doubts from space. The latest images satellites show a reality that is difficult to ignore: Russia is about to complete his largest warship in the Black Sea. The superstructure is practically complete, the flight deck is now fully identifiable and the work is advancing towards its final phase with key elements almost ready. However, this same monitoring from space also reveals the another side of the projectsince the ship remains motionless in a shipyard located within the reach of the ukrainian attack systemsmaking each advancement a race against time where finishing it is only half the challenge. Global ambition. He Ivan Rogov represents much more than a new ship for the Russian fleet, since it is conceived as a projection platform of force capable of operating far from its coasts and sustaining complex operations. With the capacity to transport hundreds of marines, military vehicles and an air wing of attack and transport helicopters, the ship fits into the category of large amphibious ships used by Western powers. Its size, greater than 200 meters, would make it in the greatest asset of the Russian fleet in the Black Sea, which reinforces its not only military, but also symbolic value within Moscow’s strategy. Born from failure. The existence by Ivan Rogov is directly linked to an earlier strategic setback, when Russia attempted to acquire Mistral-class amphibious ships from France and the deal was canceled after the annexation of Crimea in 2014. From then on, Moscow was forced to develop your own designgiving rise to project 23900which combines its own technology with knowledge partially acquired during that failed contract. This context explains why the ship has a special weight within Russian military planning, since it symbolizes both the need for industrial autonomy and the ability to move forward despite sanctions and technological limitations. Protected, but not untouchable. The ship is being built in the Zaliv shipyardin Crimea, a facility that Russia has reinforced with multiple layers of protection to reduce the risk of attacks. Physical barriers, networks against naval drones and security measures have been deployed at the access to the dam, in addition to indirectly benefiting from the air defense that protects nearby strategic infrastructures such as the Kerch bridge. However, these measures do not guarantee invulnerability, since Ukraine has shown repeatedly its ability to attack targets in depth and degrade defensive systems, keeping the shipyard within a risk zone constant. Investment under threat. Russia has maintained the project despite economic difficulties, sanctions and pressure derived from the war, which implies a huge investment of around of 1,200 million of dollars and a sustained commitment of industrial resources. This effort reflects the strategic importance that Moscow attributes to the ship, but also increases the associated risk, since the loss of the Ivan Rogov would mean not only a military setback, but also a economic and reputational blow significant. In other words, the project has become a high-risk bet for Russia where success or failure will have an impact that goes beyond the ship itself. The real change. Beyond of the specific destination of the warship, what the case reveals is a deeper change in the nature of modern warfare, one where the military industry ceases to be a safe space in the rear and becomes on a direct target. In that sense, Ukraine does not need to confront an entire fleet to weaken Russia, but can instead focus at critical points such as shipyards, energy infrastructure or supply chains, affecting production capacity before systems even enter combat. In short, the displacement of the conflict towards the industrial base alters traditional rules and demonstrates that, in the current context, a weapon can be destroyed long before it has the opportunity to be used.

A user has been powering his house with 1,000 laptop batteries and solar panels for 10 years. Others are already trying to copy the idea

by

Second Life Storage is one of those places that seems to belong to another era. In the era of Reddit and Discord, this is a forum, one dedicated to a single topic: batteries. One of its users is Glubux, and it has been sharing progress on a most curious DIY project for years: a house powered by more than 1,000 batteries. The key is that they are recycled laptop batteries. And he has created a school. Glubux Powerwall. On November 9, 2019, Glubux opened a forum entry in which he shared some photos and detailed his project: he had started collecting laptop batteries years ago, he had collected about 650 and was doing tests to check stability, performance and possibilities. Little by little he was sharing news such as the packs – cells – that he was creating with dozens of interconnected batteries with a great objective: to power the house with standard lithium batteries. These cells are not created by chance: after dissecting each laptop battery, it classifies the units by capacity and rebuilds them into stable modules. This is how it started in 2017 | Photo: Glubux The idea was to create a large system that would work together like a conventional battery, but using those recycled ‘batteries’. He tried it and ended up connecting several packs to the home power. Less than a month later, Glubux commented that it had even successfully connected a vacuum cleaner for a total of 1,200 W of power and that there were no symptoms of heating. It was time to move on. This is how it was in 2024 | Photo: Glubux The shed. But of course, if batteries have taught us anything, it is that handling them is complicated and dangerous if something goes wrong. No matter how much care we take, something so homemade is likely to fail at some point, which could start a major fire. Having something like this inside the house is crazy, so Glubux created a very small shed on his plot, but enough to house the growing collection of more than 1,000 batteries. Last year we already commented that the latest of their reports was that none had shown signs of deterioration (such as swelling) and, after eight years, they had not had to change any cells. Now, his house was running on solar panels that sent power to homemade recycled battery cells. Photo: Glubux Feeding… everything. After expanding the solar installation (24 panels with 440 W), the storage capacity increased to 56 kWh and the system, which operates at 24 volts to feed A 3 kVA converter can power the house with its lights and appliances without problem. But it is not the only thing, since it also charges both a Tesla and an electric Nissan. Creating school. Glubux hasn’t participated in his thread for a while, but that doesn’t mean he’s dead. Other users have been sharing their adventures when creating similar systems. Some were even more veteran and had more batteries, and the most interesting thing is that they have created a space in which advice is given about the cells, the capacity of each of the cells or how to join batteries so that the systems are stable. Other similar projects | Photo: Daniel88 Not so homemade. These projects are almost as exciting as finding yourself in 2026 a furo so rudimentary that it still has an active community, but it must be said that powering the house with a wall of conventional batteries is not so exotic. In fact, Panasonic recently said it was reaching the limit of its capacity to produce battery cells for data centers. These are cells very similar to those of the Glubux project although, obviously, initially created to power systems such as data center racks. They are still systems made up of packs made up of hundreds of ‘batteries’. And now I can only wonder if Glubux’s silence is because it is building its own data center next to the shed.
