Ten years ago, we were happy with microSD cards on mobile phones. The manufacturers have killed them for a good reason

by

Far was that time when buying a MicroSD card It was practically an essential for our mobile phone. The mobiles from ten years ago They came with a scarce internal memory (8, 16 GB), insufficient for devices that, despite their limitations at the hardware level, recorded Full HD video and had an ecosystem rich in applications. Today, it is increasingly difficult to find devices compatible with this memory expansion. And, yes, this is good news. The golden age of the microSD. There was a time in using an SD was the best possible option on an Android mobile. In fact, the operating system itself allowed to move some of the apps to external memories, releasing the local memory of this load. In 2010, Android 2.2 Froyo He had this option as a native from the adjustments, something that remained immovable until years later. The key was that Android was a much more insecure system than is now. In fact, with Android 6.0 It was possible to expand system storage using microSD cards. The party is over. There are two milestones that mark the progressive disappearance of MicroSD cards on Android. The first is the Popularization of Unibody mobiles: The end of the removable housings. The extra groove to incorporate the SD next to the SIM (or double SIM) hinders stagnant designs, somewhat incompatible with the Current IP protocols They protect the water and dust device. The second reason is imposed by Google with Android, and that is that the operating system was progressively restricting the permissions until they prevent them from moving apps to the SD, limiting it only to the passage of files. Reading speed. As internal memory modules have been improving progressively, reading and writing speed has shot in recent years. A UHS-1 micro SD around 200 MB/s reading speed (speeds that are never reached). EMMC’s most modern standards (slower technology in internal memories, only used in low range) can double this figure. If we talk about UFS memories, standards such as UFS 2.2 around real writing speeds close to GB, something that doubles with UFS 3.1 and almost quadruplica with UFS 4.0. Next to nothing. The size of the apps has increased considerably in recent years, as well as their requirements, and moving them from an SD is not too realistic. The focus on security. By default, the memory of any commercialized Android mobile comes encrypted, something that protects the local data of the device. SD memories do not come with this protection layer, nor do they meet the requirements to do so. Android is an increasingly sure system And, according to the latest data, it is exposed to 90% less malware than in 2016 thanks to the Play Protect scanguaranteed windows of security patches, Automatic reset and constant purge of fraudulent applications in Play Storeamong others. The microSD today. Although relegated in general terms to low -cost mobiles, The MicroSD continues to give a dummy In 2025. If your mobile has support for them, you can continue moving simple apps such as Telegram or Instagram (giants such as WhatsApp do not allow it), and even some games allow you to send part of your reading data to the SD. The same goes for multimedia: nothing prevents us from saving and reproducing content from a microSD card externally. The limitation of speed and stability (if you use a low quality microSD) will be present, but the function has not died at all. A necessary evil. Smartphones manufacturers and Google itself have been closing the door to microSD cards. It is a evil necessary to improve the stability of the system, to make Android a safer platform and continue allowing the apps to grow (in size and requirements) to the frantic rhythm to which hardware evolves.

The blackouts of Spain and London are a good example

by

A couple of months ago, a fire in a substation left without electricity To a part of London and temporarily paralyzed Heathrow airport. A month later, the Iberian Peninsula suffered a mass blackout. Two incidents separated by kilometers, but united by the same question: how fragile is the electricity grid? More than is thought. The energy expert, Simon Gallagher has addressed this topiccategorically discarding the theories of sabotage or systematic negligence relying on data provided by UK Power Networks (UKPN) and Scottish and Southern Electricity Networks (SSEN). According to Gallagher, the failures in transformers are not only common, but also expected in such a complex system. UKPN, for example, reported about 400 failures of transformers a year, although only about 30 affect more than 500 customers. Although these failures can affect from small transformers in rural posts to large urban units, the figure has remained stable. Is it stable? Simon Gallagher is based on The 2024 UKPN annual reportwhere the average customer was without electricity just 29 minutes throughout the year, which is equivalent to an availability of the service of 99,994%. This level of reliability is the result of years of investment and continuous improvement. Since 2010/11, UKPN has reduced its lost minutes by client by 55% and interruptions by 43%. A very controlled system. The British electrical system is designed with a high degree of resilience. When a component fails, there are alternative routes through which electricity can be redirected, avoiding interruptions. This capacity is complemented with automatic failure detection technologies, which isolate the breakdowns in seconds and, in many cases, restore the supply without human intervention, Thanks to self -refrarable networks or Self-Healing Grids. To this is added Predictive maintenancewhich allows to replace or repair components before they fail, and a hierarchy of equipment that minimizes the impact of the failures: a failure on a low -load transformer affects little, while high voltage those receive greater protection. This robust architecture It is backed by the Riio-Ed2 regulatory frameworkpromoted by Ofgem, which forces distributors to maintain strict standards of reliability and response. So the blackout of Spain? While the British electrical system relies on a hierarchical network with high redundancy, predictive maintenance and self -repair technologies, the recent blackout in the Iberian Peninsula has shown that the resilience of the Spanish system needs to evolve in another direction. The more you know about the incident, less weight has the initial explanation focused on the lack of inertia by renewables. On the other hand, the absence of distributed storage, The lack of micro -redes capable of temporarily isolation of the main system and low capacity of local response. The blackout, even in the absence of official information so far we know that it was not due to a generation failure but to A chain disconnectionaggravated by a centralized architecture that could not contain the domino effect. This has revived the debate about the need to modernize the network; In that sense, the British model not only stands out for its technical robustness, but also for its regulatory anticipation against high renewable penetration scenarios. How invisible it works. In a world where what fails attracts more attention, it is worth remembering how extraordinary that, despite hundreds of daily technical failures, electricity continues to reach our homes without interruption. As Simon Gallagher concluded: “Everything fails … and yet the lights remain on.” Image | Senate Agr Xataka | Saving the network after the blackout has had a side effect: more expensive light and marketers to the limit

7 out of 10 spectators were last weekend to see ‘Lilo and Stitch to the cinema. It is not as good news as it seems

by

There is no possible discussion: the absolute queen of the box office this past weekend was ‘Lilo and Stitch’, the remake in real image of the animated Disney classic of 2002. In just a couple of days he raised more than Disney had invested in it, and in countries like Spain he has been completely imposed at the box office. Raising, incidentally, doubts about the convenience that there are premieres that dominate the rest with so many clarity. The numbers sing. This first weekend, ‘Lilo and Stitch’ has collected worldwide 341 million dollars. In an unusual but very significant note, practically half of that amount, 157.8 million, has been in international markets. In this way it becomes the second best premiere of the year, just behind ‘A Minecraft movie‘. With a budget of only 100 million dollars to which you have to add up to others in marketing (absolutely key in this case), the business has been round for Disney. In Spain, even more. In our box office, According to Comscorethe thing has been even more triumphant: more than 750,000 spectators have seen it, entering about 5.7 million euros in 1107 screens, that is, the best premiere of the year. Thanks to Disney, the box office receives a welcome oxygen ball, becoming the best weekend of 2025. For comparing, the general box office has been 205% higher than the previous weekend. Without rival. In total, this weekend 8.3 million euros and almost 1.1 million viewers have been raised in all movie theaters. From there, the accounts are simple: 70% of the weekend market share corresponds to titles distributed by Disney in Spain (remember that films such as ‘Thunderbolts’ are still running). That is, the collection of ‘Lilo and Stitch’ is 67% of the Spanish total box office. Or in other words: 750,000 spectators against 1.1 million. 7 out of 10 spectators have seen the Disney movie. La Puntilla: ‘Mission Impossible’. The eighth delivery of the adventures of Ethan Hunt de Tom Cruise has finished rounding a weekend absolutely marked by the blockbusters: the film has entered 190 million worldwide, of which 1.55 million euros have been in Spain. Here is the fifth best premiere of 2025 and they are not absolutely spectacular figures, but we take this into account: of those 3 out of 10 spectators who did not enter ‘Lilo and Stitch’, As the box office expert Pau Brunet saysmore than half saw Tom Cruise’s movie. Short -travel nostalgia. ‘Lilo and Stitch’, regardless of their box office or its limited creative interest, is an interesting exhibition of the state of things: the nostalgia of generation X and millennials, exploited, of millennials, exploited, It is the turn of generation Z. This film is the first to go to the memories of such a young generation: the original film represents the sunset of Disney’s Golden Age, with the advent of Pixar and primed by the last VHS copes, where the sequelae of the film were released. A twilight environment for animation cinema that is now remembered with love. The teddy business. That is why that investment of 100 million euros in marketing makes sense. Stitch’s stuffed animals and dolls have been the great surprise triumph of merchandising of Disney products in recent years: since 2019, annual sales of character -related products have gone from 200 million dollars to exceed 2.6 billion dollars in the last yearaccording to ‘The Wall Street Journal’. And that is just the most visible part of the business: Stitch has become one of the undisputed stars in Disney attractions parks, and the products with the alien face They multiply without rest. The danger of success. Although all this are excellent news for Disney, to the box office (especially Spanish) leaves it in a complicated situation: hypertaquillea films such as ‘Lilo and Stitch’ or ‘Impossible mission 8’ are magnets that attract viewers … to the detriment of the rest of the movies. Although the box office has shot thanks to Disney, 16 titles are distributed Collection crumbs: 474,000 euros. Insufficient to lift a box office that needs the crutch of a couple of Blockbusters To take oxygen, which undoubtedly does not give too many hope about the good health of movie theaters.

A marginal city in Italy established a direct flight with New York. Now they are not so clear if it was a good idea

by

In front of massive cities Like Venice either Romein Italy there are other enclaves that look with some envy how the economies and investments produced by the paradoxical arrival of the arrival of Tourist hordes. One of those places was Bari, until recently a marginal port city with high crime rates. Then it was decided that it was time to fly and hug tourism. What happened later has left them serious doubts with the decision. The new jewel. I told this week The New York Times. After decades of being seen as a secondary scale on the way to more famous destinations in southern Italy or the Greek Islands, the port city from Bari He has begun to become an unexpected protagonist of European tourism. This metamorphosis has been largely driven by the effort of Antonio Maria Vasile, director of the airports of Pugliawho managed to establish the First direct flight Between Bari and New York, a symbolic bridge between the region and the millions of Italian Americans who share that origin. With this international connection, Bari seeks to claim its place not as a relegated south, but as a vibrant center of culture, history and gastronomy. Although for years his old town was Synonym of crime And abandonment, the city has experienced an urban rebirth that has given way to coastal walks, coffees, cultural routes and, very important, security, returning to its inhabitants a sense of pride so far scarce. First tourist line. He counted the medium that Puglia has silently conquered celebrities, investors and tourists, and has done so with its mix of crystalline sea, baroque architecture, rural hospitality and discreet luxury. While resorts like Burgi Egnazia They welcome G7 peaks And the Lamborghinis wait in the rental garages, Bari begins to benefit from the Halo effect which has elevated the region to the new epicenter of the Italian charm. The legacy of San Nicoláswhose grave is in the city, joins a Bari Vecchia completely renovated, where the medieval churches and the street sale of Orechiette They compete in attractive with The focaccia local. The walks through the historic center, before dominated By mafia clansnow they are full of visitors and residents who rediscovered the city with new eyes. In other words, the narrative of the impoverished and forgotten south begins to give in to a modernity, heritage and opportunity. Gentrification No doubt, this also entails others known evilsbecause the tourist boom does not come without tensions. The sudden popularity of Bari has Turned prices of the rent in the center, expelling pensioners and students, and putting in check To the young population which represents the demographic and creative future of the city. The massive reconversion of housing in tourist rentals has emptied traditional residential areas, repeating Dynamics seen In other saturated cities Like Venice, Madrid either Lisbon. Thus, more and more people fear that, after having rebuilt their identity, Bari loses it under the pressure of an economic model seasonal and fragile. Criticism also aims at the lack of investment in public transport, a basic lack that hinders both the daily mobility of residents and the full integration of tourist flows. As a local teacher synthesized to the Times: “In Puglia it is easy to rent a Ferrari, but finding a bus is another story.” Between the authentic and the fanfare. Explained at the NYT that Bari’s revitalization has been so deep that those who knew her in her most decadent stage barely recognize her. Ancient neighborhoods now shine with cultural routes, film festivals and a nightlife that, however, has begun to collide with the traditional social fabric, as was demonstrated recently when the neighbors They threw water cubes to disperse the hordes of tourists of the San Nicolás Festival. Enthusiasm coexists with the same concern of so many other enclaves: Can a city reinvent itself without selling itself completely, attract without blurring? The answer is not clear and, meanwhile, Vasile imagines a future where Bari does not depend on fleeting summers or celebrity names, but on a deep and sustainable consolidation. Under that prism, the new connection with New York should not be synonymous with tourism without more, but in his words“The inaugural symbol of a different era. We have realized new possibilities.” Now it remains to be seen if the city knows how to become a reality … without losing its essence along the way.

Good news, the solar system has a new minor planet. Bad news, it’s so far that appears every 25,000 years

by

The International Astronomical Union has added a new celestial body to its Minor planet catalog: The Transneptunian object 2017 of201. The solar system has a new member. 2017 of201 has been officially recognized as a minor planet, but has many ballots to end also cataloged as a dwarf planet. This icy world, which orbits much beyond Neptune, in the dark depths of the solar system, was in file data since 2011, but 19 exhibitions were needed over seven years to be able to analyze and classify it as appropriate. What makes this transneptunian object a fascinating world are two things: its incredibly extensive orbit and its considerable size. The new minor planet takes approximately 25,000 years to take a single round to the sun. A distant and not so dwarf planet. At its closest point to our star (the perihelium of its orbit), it approaches about 44.9 astronomical units, a distance similar to that of Pluto. But at its furthest point (its apelium) it ventures to amazing 1,600 UA. To get an idea, Neptune, the planet known more distant to the sun, orbits about 30 UA of our star. The estimates of astronomer Sihao Cheng and his team of Advanced Studies Institute They suggest that 2017 of201 has a diameter of about 700 kilometers. This would place it in the same league as The Dwarf Planet Ceresthe largest object of the asteroid belt (with about 952 km in diameter). In fact, if we judge it for the light that reflects your body, it is the second largest object known In such a wide orbit and eccentric. What if there were others like him? The existence of 2017 of201 suggests that the region of the solar system beyond the Kuiper belt, which was thought relatively empty, I might not be so much. The transneptunian object is currently 90.5, from us. Since it is only detectable for approximately 0.5% of its orbital time, when it is close to its perihelium, there could be hundreds of similar objects, with orbits and similar sizes, waiting to be discovered. This hidden population could add a total mass close to 1% of the dough of the earth, they estimate Cheng and its team. It takes us away from the planet nine. Many extreme transneptunian objects tend to coincide in their perihelium lengths, a phenomenon that some astronomers want to attribute to the gravitational influence of A mass planet not yet discovered: The planet nine. However, the 2017 of201 perihelium length is 306 degrees, which is significantly diverted from the 60 degree group observed in other objects. This orbital peculiarity Challenge the planet models nine. If the planet nine would exist, it would make 2017 of201 expelled from the solar system in relatively short time scales, of hundreds of millions of years, according to the study of IAS. You just lack a name. Already officially member of the Solar System, 2017 of201 is pending to receive a name with more hook. However, its discovery is already providing clues about the origins of the solar system and the dynamics of its most remote confines. What most excites the scientific community is that its discovery was possible thanks to open data, publicly available through the Dark Energy Camera Legacy Survey (Decals) project of the Víctor M. Blanco telescope and the Canada-France-French telescope (CFHT). Image | NASA/JPL-CALTECH, SIHAO CHENG et al. In Xataka | Planet’s definition is wrong, and Pluto is the great victim of that chaos

Germany is installing giant concrete spheres under the sea. You have a good reason: store renewable energy

by

While France and Germany reinforce their energy alliances with a renewed bet For nuclear energy, within the German country they are developing a completely different system. The focus is on marine depths, with the aim of redefining the way in which renewable energy is stored. Under the sea. A group of researchers the Fraunhofer Institute of Germany They have created the Stensea project (Stored Energy AT Sea acronym). Since 2011, the equipment has worked in a solution to reduce land use, reaching the conclusion of sinking huge concrete spheres into the seabed to store energy. The operation. These spheres sink at 600 and 800 meters deep, where water pressure is so high that it can rotate turbines with great efficiency. Each one measures about 9 meters in diameter and weighs about 400 tons. The idea is that they work as giant batteries: by letting the sea water in, it moves a turbine connected to a generator. To recharge it, water pumps out, using network energy to overcome environmental pressure. A design of what a Stesea plant would be A real test. The system has already been successful at Lake Constanza, and now the next step is marked in the calendar by 2026. It is expected to install a prototype real and 3D printed on the coast of Long Beach, in California. This model can generate about 0.5 megawatts and store up to 0.4 megawatts-Hora, which would be enough to cover the consumption of a middle home in the United States for about two weeks. The future idea is ambitious: building much larger spheres, up to 30 meters in diameter, capable of storing much larger amounts of energy. The objective is to climb the system with spheres up to 30 meters in diameter, which would allow a much larger storage capacity. According to They have detailed Newatlas researchers, the estimated storage cost around the 5 cents per kilowatt-hora, a very competitive figure compared to other current solutions. Renewables in Germany. Although it seems contradictory for its climate, the country has been strongly betting on solar energy, especially In self -consumption facilities. However, it faces an important challenge: intermittent production, or Dunkelflaute. For this reason, projects such as Stesea can act as a shock absorber of the electrical system, because it stores excess renewable energy and releases it when it is most needed. So hydroelectric plants? Unlike traditional pumping storage –which requires mountains and large fresh water reserves-, this system does not need limited elevations or water resources. Its modular design allows it to install it on coasts around the world. In addition, this system has raised An economic advantage since it allows energy arbitration, buying electricity when it is cheap and selling it in moments of high demand. Forecasts The researchers They believe that this technology He has barely shown the tip of the iceberg. They estimate that, if it was deployed on a large scale, it could reach a global storage capacity of about 817,000 gigawatts-Hora. Translated to something more tangible, it would be enough to supply about 75 million homes in Europe for a whole year. However, although the project is presented as a solution to avoid intensive soil use, it does not stop moving that occupation to the seabed. Until now, the approach has been mainly technical, but it would be expected that in future phases rigorous environmental evaluations will be included that analyze its impact on oceanic ecosystems.

Your participations are increasingly problematic and there is no good solution

by

It may be The voting systemit may be the opposition of some rebel televisions, but what is indisputable is that Eurovision has a problem with Israel. A hot potato that generates controversy and division between fans and is the main reason that this year, a couple of days after the celebration of the contest, we have stopped talking about music. However, the history of Israel and Eurovision goes back far back in time. Why does Israel participate in Eurovision? Israel is not a European country and yet Participate in full in the contest. This is due to the fact that it belongs since 1957 to the European Broadcasting Union (URU), the organization that produces and regulates the festival, an international corporation of broadcasting of ownership and public service, but without linking to the European Union. Countries such as Armenia, Azerbaijan, Georgia and Australia participate under the same conditions. A long history. Israel debuted in the contest in 1973, being the first non -European country to do so. Since then, he has competed more than fifty. They have won in four: 1978: Izhar Cohen & The Alphabeta with ‘A-Ba-Ni-Bi’ (157 points). 1979: Gali Atari & Milk and Honey with ‘Hallelujah’ (125 points). 1998: Dana International with ‘Diva’ (174 points). 2018: Netta with “Toy” (529 points: 212 of the jury and 317 of the Televoto). Thanks to this they have had the opportunity to celebrate the contest three times, in Jerusalem (1979 and 1999) and Tel Aviv (2019). They resigned to do so in 1980, for coinciding the festival with the day of the memory of the Jewish holocaust. His career is especially remarkablereaching Top 10 on twenty occasions. Comparisons with Russia. Israel’s presence in Eurovision has been criticized since 2023, when The war started in the Gaza Strip. The first thing that was accused of Eurovision was of a certain hypocrisy for not expelling Israel as it had done in 2022, vending Russia After the invasion of Ukraine. The justification of Eurovision was that the contest is a competition between public broadcasters, not governments, and that Israeli public television (Kan) continues to meet the requirements of editorial independence and public service that, however, considers that Russian public chains have lost. Songs with problems. Already that same 2023, the song with which Israel participated in the contest, ‘Hurricane’, played by Eden Golan, He gave problems because it was suspected that its lyrics contained evening allusions to the attacks of October 7. The lyrics and the video clip used metaphors that reminded the young people fleeing from the attack at the Nova Music Festival, where Eden was one of the survivors. Finally, Israel maintained its participation after threatening to retire Yes ‘Hurricane’ was disqualified. Too many interests. But if your participation is so problematic, why don’t Eurovision exclude Israel? This is a network of interests where the sponsorship and financing of the festival stands out: since 2020, the main Eurovision sponsor is Moroccanoil, a company of cosmetics of Israeli origin that performs 80% of its production in Israel and has a continuous presence in the contest, from its appearance in all the curtains and scenarios to the styling of the artists. The brand has been accused of manufacturing in occupied Palestinian territories. Different sources point out that Moroccanoil would withdraw a very juicy sponsorship if Israel was expelled from the contest. The Eurofans protest. Next to the controversial votes, in social networks A series of videos have been seen that they result in the idea that the televoto has little to do with the desire of the authentic fans of the contest: constant boos In Israel’s performance, Palestinian flags that they have not been able to be hidden by realization, expulsions of spectators In essays … the contrast between Eurofans (even among those who advocate The impossible: that the contest is apolitic) and the televoto mediated by pro-Israeli media and organs is more pronounced than ever. It has its fans. But of course, there is the other side of the equation: we cannot forget that, despite the protests of many Eurofans, Israel has won the contest with authentic classics. Especially notorious was Dana International’s performance in 1998, which was a step forward in the LGTBI representation in Eurovision, giving to a large extent the contest we know today. Eurovision is largely its LGTBI audience, and Israel took a giant step in its day in that direction, something that many followers still remember and thank. It is also unfair to say that the entire televoto, however broken the system, was mediated by political interests: the trajectory at the Israel Festival demonstrates that their themes have genuine defenders: the controversy of its presence only dates back a couple of years ago, but historically Israel has gone well stopped the voting since the seventies. The protests of Spain and Belgium, in short, are exceptions: most European governments support Israel’s policy, and that also influences the positioning of their voters in Eurovision.

The bad news is that the oxygen of the Earth has an expiration date. The good is that we will not be here to see it

by

We can breathe calm. Also the grandchildren of our grandchildren’s grandchildren. But the oxygen that supports complex life on Earth will not be eternal. Our oxygen -rich atmosphere has approximately one billion years. So, the change will be drastic. A rapid dexygenation. An international study published in Nature Geoscience Details the calculations. After making more than 400,000 simulations on the geological and biological evolution of our planet, Japanese and American scientists came to the conclusion that the Earth will experience rapid dexygenation that will return it to an atmospheric state similar to that of the archaic land of about 2.5 billion years ago. What the sun gives you, the sun takes it away. Until recently, the scientific community estimated the life expectancy of the Earth’s biosphere in another 2,000 million years, when global warming at geological time scales leads to the evaporation of the oceans. But this new model projects a different scenario. According to researchers, the increase in solar radiation will intensify the cycle of carbonates and silicates. This will cause a drastic decrease in carbon dioxide concentrations. With less co₂, photosynthetic organisms such as plants, the main oxygen producers, will die. The result: a vertiginous fall of atmospheric oxygen. If perhaps, anaerobic life will remain. With a millionth of the oxygen we have today, complex life forms will be extinguished long before the oceans boil and the planet is left without surface water. For the vast majority of life forms, whose metabolism depends on oxygen, this will be the end of the road. The model indicates that deoxygenation It will happen at 1,080 million years (with a deviation of ± 140 million years). By then, the earth’s atmosphere will be radically different, with high levels of methane, low carbon dioxide levels, and a total absence of ozone layer. With luck, it will be a world of anaerobic life forms. And what is this data for us. Although we will not affect us, nor the grandchildren of our grandchildren’s grandchildren, the study, funded by the Nexus for Exoplanet System Science Science project of NASA, has important implications for the search for extraterrestrial life. It suggests that an oxygenated atmosphere is not a permanent characteristic of habitable worlds. Oxygen, and its photochemical by -product, ozone, are two of the biofirms that seek space agencies in exoplanets. If the oxygen rich atmosphere of the Earth will last between 20 and 30% of the total life of the planet, other planets similar to the Earth could now have weakly oxygenated or anxic atmospheres. The search for life beyond our solar system will have to expand its scope to other biological firms.
