the social network is down worldwide

If you’re trying to log into X (formerly Twitter) and all you see is an empty screen, you’re not alone. From approximately 2:00 p.m., the social network owned by Elon Musk It has started to fail and currently you cannot read any posts either from the website or from the app. General decline. Downdetector It is one of the most popular websites to check if a service is down at a specific time. Around 2:00 p.m., failures began to be reported, which quickly escalated. An hour later they have already reached almost 4,000 reports only in Spain. According to Tech Radarin the US there have been more than 40,000 reports and more than 3,000 in the United Kingdom. in the tool downforeveryoneorjustmereports have been received from Greece, Brazil, Türkiye, Australia, Sweden, South Africa… Indeed, it is a global fall. 23 TWITTER TRICKS – Completely dominate this SOCIAL NETWORK! Web and app. The failure is occurring at the service level, meaning that both the website and the app are down. If you try to log in, your screen may go blank (or black if you have dark mode) or you may see a “Something went wrong” message. Accessing from the app we see the message “Posts cannot be retrieved at this time.” And now what. Twitter is the place where we usually go to stay up to date when an important event occurs, as well as when other services go down. Let us remember the massive fall of Facebook and all its services in 2019a blackout in which Facebook itself used Twitter to communicate with users. It is a very common practice. A few weeks ago Spotify fell and the statement also came through X. Where does X communicate when X falls? we don’t know In development….

Yes, the DGT has limited the maximum speed to 80 km/h and has prohibited overtaking. And there’s a good reason for that: wind.

In Spain the weather is bad. I don’t know if you had noticed but we have had rain, snow and very strong winds for a month and a half. Meteorological events that are impacting all types of sectors. Also that of mobility, where closed roads, incidents on the road and restrictions are being the general trend. If you go to your favorite social network and read that the DGT has limited the speed to 80 km/h, don’t panic. It’s normal. At 80 km/h maximum. And overtaking prohibited by order of the DGT. It is a headline that has been repeated in the last two days and has spread across social networks. Headlines that hid an essential word to understand the information: temporal. Meteorological storm, because the restrictions are due to the clash of storms that we have chained for days and weeks in the Iberian Peninsula. And temporary because the restrictions are not definitive, they are simply used to maintain safety on the road. The restrictions. One of the provinces that found the most restrictions of this type during the past weekend was Castellón. The region has had to live with an orange alert for wind and the DGT decided that the maximum speed at which one could drive on Saturday was 80 km/h on three roads in the province, where overtaking was also prohibited. The trucks They were also not allowed to circulate on the AP-7. Yesterday, Sunday, normality was recovered. These restrictions have obviously been temporary. And, effectively, the DGT can apply temporary restrictions on speed or overtaking for meteorological reasons, just as can close a road to traffic due to snow or it can be restricted to those who They drive with chains or winter tires. For security. The wind is a danger on the road and overtaking is critical when there are very high wind gusts. In particular, some are very dangerous: Screen effect: when you drive through a tunnel or infrastructure that cuts off the side wind and it disappears. At that moment, a gust of wind can move the car to one side of the road and If we are caught off guard the movement will be sharper. Overtaking: something very similar happens when we overtake a large truck or van. In this case, if we are fighting a crosswind, passing a vehicle will automatically cut off the force we receive. You have to be careful because normally we have been moving the steering wheel to the right slightly to counteract the force of the wind. By overtaking the truck, that resistance disappears and we can go against the vehicle on our right, adding that the truck or van fights not to go to the left, which can end in contact. Furthermore, when overtaking, we will again feel the screen effect described above, so we must be careful and remain attentive. Trailers: Both situations are especially dangerous if we drive a vehicle with a trailer since, in that case, the car does not receive the same forces as its rear part and, in an extreme case, movement angles that are difficult to manage can arise. What does the DGT recommend? The first thing we must do is adapt our speed to the traffic circumstances. The DGT has the power to reduce the speed of the road to 80 km/h and prohibit overtaking, but the logical and essential thing is to apply common sense and take your foot off the accelerator. Taking this into account, we must remain very attentive to resolve any gusts of wind. If this happens, you have to act gently, calmly. The DGT also recommends circulate in high gears (one lower than usual) to have a greater response from the engine if we need to get out of trouble. And remember that the more voluminous and taller a vehicle is, the more risk it has of overturning, the more complex it will be to control it and the more care we must take when overtaking it.

After the Fukushima nuclear accident, the pigs on the farms fled into the forest. Years later they were something different

March 11, 2011 was one of the darkest days in Japan’s recent history. And probably the worst so far in the 21st century. An intense earthquake recorded off Honshu unleashed a tsunami with waves of more than ten meters that ended up precipitating an accident at the Fukushima plant. You have to go back to 1986, to Chernobyl, to find a similar incident. Today we know that that chain of misfortunes had an unexpected consequence: it gave rise to an involuntary experiment with pigs and wild boars. Pigs on the run. After the Fukushima Daiichi accident in March 2011, authorities rushed to evacuate all the people living in a radius of 20 kilometers of the nuclear power plant. Even those residing 20 to 30 km away were advised not to leave their homes. Today, a decade and a half later, we know that the Fukushima incident had another consequence: the pigs that until then were raised in domestic farms fled and took refuge in the forests, places that until then had served as home to wild boars. An XXL laboratory. The escape of the Fukushima pigs (and their clash with the wild boar populations) could have remained a minor anecdote if it were not for the fact that it gave rise to a curious improvised experiment. An involuntary one, which no one had planned, but which, due to the chances of history, ended up turning the forests of the exclusion zone into a gigantic zoological laboratory. The reason? Escaped pigs and wild boars ended up mating. “Without repeated introductions and minimal human activity, the region became a rare natural hybridization experiment,” explains Fukushima University. The experience was certainly interesting enough to attract the attention of Shingo Kaneko and Donovan Anderson, from Hirosaki, who decided to carry out a genetic study to better understand the results of crossing pigs and wild boars. Their conclusions have just been expressed in a published article a few days ago in the magazine Journal of Forest Research. What did they find out? Perhaps the most surprising has to do with the renewal of populations. Domestic pigs and wild boars differ not only in their appearance. They also show different patterns. For example, while the latter reproduce once a year, the former, the pigs we raise on farms, show a much faster cycle throughout the year. Kaneko’s study shows that this peculiarity of domesticated animals was maintained after their escape and was transmitted during hybridization through the mother. five generations. There is one piece of information that helps to better understand how accelerated its reproduction rate has been. For their study, the researchers analyzed the mitochondrial DNA and genetic markers of more than 200 animals captured over three years, between 2015 and 2018. One of the first questions they tried to clarify was: How related were these specimens to the pigs that escaped in 2011? How many came from that domestic lineage? Their conclusion was surprising: many hybrids were already more than five generations away from the original cross, suggesting “unusually rapid genetic renewal.” they add from Fukushima University. “Although it has previously been suggested that hybridization between pigs reintroduced into the wild and wild boar could contribute to population growth, this study shows, by analyzing a large-scale hybridization event following the Fukushima nuclear accident, that the rapid reproductive cycle of domestic pigs is inherited through the maternal lineage.” A diluted inheritance. It was not the only conclusion that the experts reached. Another, just as curious, is how hybrid creatures evolved. That domestic females favored a higher rate of reproduction does not mean that their inheritance was more pronounced. Quite the opposite. Farm sows energized generational renewal, but the initial strength of their genes was diluted little by little. “Rather than prolonging the genetic influence of domestic pigs, maternal pig lineages actually accelerated genetic turnover in wild boar populations,” apostille from Fukushima. Why is it important? The research is not interesting only for what it reveals to us about the Fukushima exclusion zone. Their conclusions go further and have practical implications for the rest of the world. Experts have long been concerned about hybridization between domestic and wild animals (especially between pigs and wild boars) due to its ecological repercussions. Curiously, the accident that occurred in Japan in 2011 has offered researchers a huge laboratory to better understand the phenomenon and how to address it. “The findings can be applied to wildlife management and invasive species damage control strategies,” Kaneko celebrates. “By understanding that the pig’s maternal lineage accelerates generational turnover, authorities can better predict the risks of population explosion.” Images | Max Saeiling (Unsplash), Wikipedia and Fukushima University In Xataka | An unprecedented experiment is happening in Ukraine: bombs have turned dogs into other animals

“We are willing to further strengthen cooperation with the Spanish parties”

Europe continues to discuss how to deal with China. Spain, meanwhile, has already opened all its doors. Several times. The International Department of the Chinese Communist Party (an organ of the Party, not the State) has made Madrid a mandatory stop for its parallel diplomacy. At the end of January, Vice Minister Ma Hui toured the offices of the PP, the PSOE, the PCE and the Catalan Generalitat. No one closed the door. Why is it important. China is not looking for ideological allies in Spain, what it is looking for is access. Their strategy is to build relationships with whoever governs today but also with whoever can govern tomorrow. The CCP’s International Department maintains contacts with more than 600 parties around the world because it does not understand colors, only influence. And Spain, due to geography, economy and political predisposition, has become its bridgehead in southern Europe. Between the lines. Zapatero once again appears as a key piece of this network. Ma Hui, a veteran diplomat and former ambassador to Cuba, met him first, before anyone else. It is not coincidental. The former president maintains recurring contacts with CCP structures, appears at Party-sponsored forums in Beijing and operates as an unofficial facilitator. A role that raises questions about transparency and red lines in international relations, especially for someone without official position but with privileged access, which we now know is is on the payroll of a Chinese manufacturer to help it deploy in Europe. The contrast. Trump has based part of his legislature applying tariffs and generating uncertainty with them. China, meanwhile, has wanted to position itself as its opposite, as a guarantor of tranquility. It has presented its Five-Year Plan (2026-2030) in Madrid as a model of stability. Yes, but. Spain is moving with respect to China faster than the rest of Europe. Pedro Sánchez plans his fourth trip to Beijing between April 13 and 15. And this pace makes Brussels uncomfortable because it is trying to coordinate a common European position towards China. Spain can clearly benefit economically from this stance, but at some point we will have to ask ourselves what we are giving up in exchange. The money trail. China no longer only pursues markets in Spain, it pursues political legitimacy: Ma Hui participated in a forum Chinese Chaira think tank geographically close to Atocha but strategically very close to Beijing. These spaces, halfway between academia and propaganda, normalize the Chinese presence in European decision-making centers. They say they want to “learn about state management.” In reality, they build a network of interlocutors that facilitate their strategic interests. ¿Main loser? The common European position. If Madrid negotiates on its own, Valencia too, and Barcelona the same, China does not need to convince the European Union. It is enough to fragment. Bilateralize what should be multilateral. And Spain, with former leaders operating as unofficial liaisons, facilitates that strategy.

call the US or be the last with an endangered fighter jet

There was a time when Spain decided that it did not need the large aircraft carriers of the superpowers to have combat aviation at sea. So he opted for a bold solutionalmost experimental, that fit its geography, its naval ambition and its resources, and that would end up becoming a sign of identity for decades. Since then, that unique aircraft has been linked to the Navy in such a profound way that it is difficult to understand its history separately. And now you are faced with a dilemma. Pioneer in stoppage time. Yes, for approximately half a century, the Spanish Navy built a singular identity in Europe by operating fixed-wing fighters from the sea without the need for large aircraft carriers, relying on the Harrier as a central tool of deterrence, projection and expeditionary support. That strategic advantage, which made Spain an international reference since the seventies and allowed it to operate in real scenarios like the Balkansnow comes to a critical point: the aircraft that made it possible enters its final phase of useful life just when the rest of the operators leave the platform and the technological and doctrinal environment of naval air combat has completely changed. The isolation of the Spanish Harrier. To understand it, two facts are fundamental: the imminent withdrawal of the AV-8B Harrier of the United States Marine Corps and the italian transition towards the F-35B, movements that leave Spain on track to become the last world operator of the model. This scenario is not only symbolic, but deeply practical: it means being left alone with a logistics chain that is shutting down, with production stopped for more than two decades and with a growing dependence on one-off agreements, cannibalization of cells and increasingly scarce spare parts. Extra ball. Although the Navy hopes to extend operations until 2032 through agreements with the United States and management extremely careful of the fleet, the truth is that with each passing year reduces safety marginsincreases risks and increases the cost of a capacity that no longer has a medium-term future. Harrier of the Spanish Navy The technological abyss in front of the network. Beyond sustainment, the dilemma is operational. Of course, the Harrier is still a valid aircraft for certain missions, but it belongs to another era of air combatone where information was concentrated in the cockpit and survival depended largely on the pilot and limited sensors. In front of him we have to talk again about an “old acquaintance”, because the F-35B represents a qualitative leap that does not allow comparisons gradual: it is not just a fighter, but an intelligence node capable of detecting, merging and distributing information in real time to ships, aircraft and allies. For a ship like the Juan Carlos Ithis difference marks the border between conditioning the adversary or limiting oneself to reacting with increasingly exposed means. The problem, in this case, is already we have commented: Spain, a priori, does not seem willing to do so. FCAS and the lack of enthusiasm. Also it we count last week. The FCAS program often appears in the debate as a lifeline industrial and European politics, but it does not solve the problem embarked Spanish not even in its most optimistic scenarios. If we ignore that at this moment the project is more outside than insideit is a system designed for air superiority from land bases, without STOVL design nor compatibility with ships like the Juan Carlos I. In fact, turning it into a naval solution would require building a conventional aircraft carrier, redesign doctrines, assume colossal investments and wait decades. In real terms, FCAS does not replace the Harrier or avoid the vacuum that will open if decisions are not made in the short term. The F-35B and realism. In 2026, the F-35B is not a perfect or cheap option, but it does aim to be the only existing platform capable of directly replacing the Harrier and keeping the Spanish embarked fixed wing alive. With more than a thousand operational units and a growing community of naval operators, it offers continuity, interoperability and a military relevance that the Harrier can no longer guarantee alone. From that prism and although Spain it doesn’t seem For the work, giving up this fighter does not mean saving so much as accepting a decade or perhaps more without an embarked combat aircraft, which in the long run could degrade the Juan Carlos I to a helicopter and drone ship with limited capabilities in the face of an increasingly disputed environment. Maybe not, but that idea flies over if there is no replacement for the Harrier. A strategic dilemma. Thus, the underlying or “nuclear” problem is not choosing between airplanes, but rather deciding What role do you want to play? Spain in the naval and expeditionary field. Keeping the Harriers to the limit without a clear relief leads to a loss of capacity hardly reversible, while recovering that aptitude in the future would require much higher costs and efforts. Meanwhile, the clock is ticking, partners are moving forward, and the Navy is faced with a decision that will define its relevance operational for decades: that of continuing to be an actor with an embarked fixed wing or accepting, through inaction, the silent end of one of its most emblematic capabilities.

The question is not how many will you buy, but why do you want us to know?

The news comes from Mercadona itself: During 2026, it will market “more than 14 million kilos of avocados of Spanish origin.” That is 18% more than last year and, in addition, it represents 95% of all avocados that will be sold until April. And yes, this seems good news for Trops, Surfruit or Avocoop (agri-food cooperatives in the sector); But the relevant question is why is Mercadona interested in making all this clear? Clarifying the data. Mercadona’s statement comes now that the avocado campaign begins in Spain and its 95% commitment extends until April, when the campaign ends. That is, in part, it is a defensive advertisement. For years, large distributors have been criticized for not selling national products and sometimes it is true: it is often cheaper to buy outside than inside and many customers do not show any preference for national products. However, it is not always a fair complaint: if we want to have avocados all year round in supermarkets, most of it has to come from outside. With these types of adsthe Valencian chain (and the rest) tries to “minimize” the reputational damage linked to the sale of Moroccan, Peruvian or Chilean avocados. “But they are going to buy 18% more.” It’s true. And the company explains that it is due to the rise in demand and its commitment to the national product. However, we cannot ignore that we are coming from campaigns very affected by the lack of water in the main producing areas of the country. Only in Andalusia the production fell in 2023/24 34% compared to 2019/20. It is true that in 24/25 production recovered (it went from 56,000 tons to 75,000) and that in 2025/26, thanks to water and the entry of new plantations, it is expected a growth of 25% with respect to the previous year. That is to say, Mercadona’s 18% is worthy, of course; but it is not particularly striking: there is now avocado to cover demand and at a lower price than in recent years. The problem of “national origin.” Mercadona’s move is also dovetailed with another underlying movement. Spain has realized that the hyperdependence of the national market on Andalusia is a problem. After the droughts of recent years, Valencia has gained weight and even Asturias (that already leads the production of kiwis) is considering betting on “green gold”. That restructuring of the agricultural sector is key. Because Spain is a great agri-food producer, yes; but even more so, it is a giant in the international distribution of imported products. And, although it may not seem like it, both things They are more related than it seems: They are communicating vessels and if one fails the other suffers. What we can expect. This is, without a doubt, the biggest problem: that in the midst of this climate chaos, regulatory and sociopolitical It is very difficult to make long-term estimates. And yet, there is no worse time to not make decisions. Therefore, the fact that large distribution chains have the Spanish agricultural fabric in mind is excellent news even if we take into account that, well, there is a ton of marketing in all of this.

there was a “hybrid zone” of 4,000 kilometers

For years we had a fairly clear narrative in our minds of what had happened to our ancestors. The specific story is that the Homo sapiens They left Africa, met some Neanderthals somewhere in the Middle East, had a couple of chance encounters of hybridization pulses and they continued on their way to conquer the world. A change. However, a massive new study that just appear on the bioRxiv preprint server suggests that that picture is too simplistic. They were not specific meetings, but rather a continuous interaction throughout a huge “hybrid zone” which spanned from the Near East to Central Asia and Europe. To get here, the study has analyzed an unprecedented amount of ancient DNA to draw the most detailed map to date of how we intermingled with our extinct cousins. and the result It is a gradient of miscegenation which extends for almost 4,000 kilometers. Lots of volume. The study has not been limited to a few bones that have been found in isolation, but has used computer simulations and a data set of 1,264 paleogenomes. Something that corresponds to thousands of individuals older than 10,000 years. Your conclusion. The Neanderthal DNA patterns that we carry today in our genetic material They are not well explained by “isolated pulse” models, but rather the symmetry found between the genomes of Europe and Asia indicates that there was prolonged contact. In this way, as modern humans expanded out of Africa, which is what we know as Out of Africa, about 60,000 years agowere pushing a demographic frontier. On this advance front, gene flow was moderate but constant. That is why it was not a one-day event, but a long geographical process. The how. To understand this you have to look complementary studies which suggest that the key is in spatial gradients. To visualize the concept, we can imagine a wave that advances as if they were the Sapiens who were moving and encountering the Neanderthals. But the key is that Neanderthal ancestry is not uniform. This means that the first sapiens in Europe had a high level of Neanderthal DNA, but later expansions, such as the arrival of Neolithic farmers from Anatolia, they “watered down” that Neanderthal heritage, especially in Europe, creating a notable difference with the populations of Asia. This is where the study presented in 2026 confirms that only a model of persistent expansion with gene flow can explain why we find signs of interbreeding almost 4,000 km from the point of origin in the Near East. When did it happen? This is where things get interesting when crossing the data with other recent studies, like the one published in Nature in 2024. And although the area was large, the time window was critical. Analysis of more than 300 early human genomes points to a “single window” of major hybridization between 47,000 and 43,000 years ago. This excludes previous theories that suggested multiple, very ancient pulses. And to go a little further, there was a moment, when our species was securing its dominance in Eurasia, when the barrier between species blurred across a huge geographic swath. A map of interactions. What this body of research suggests is that the hybrid zone encompasses almost all of the Neanderthal sites known as Western Eurasia, so it implies geographically extensive interactions. However, as is often the case in science, caution must be maintained. This study has yet to undergo a full review and has limitations in that it is based on demographic assumptions and that it does not model the natural selection that we have in the genetic world. Even so, the image is increasingly clear: we are not the result of one species that replaced another suddenly. We are, in part, the result of a long border of contact where, for millennia, the line between “them” and “us” was much more blurred than we thought.

step by step of the online process

Let’s explain to you how to register your electric scooter in the DGTone of the procedures that all owners of these vehicles they must perform in addition to having mandatory civil liability insurance. As you already know, this new regulation finally begins to put a little control on electric scooters in Spain. Specifically, the standard affects all vehicles with one or more wheels that are moved by electric motors and that reach speeds between 6 km/h and 25 km/h.
