They are becoming more and more short

by

Aemet He has just published his prognosis For the next three weeks and there is only one valid conclusion: winter is over. It is true that the forecast is not very surprising because, on the one hand, winters are increasingly short and warm and, on the other, the weather spring begins on March 1. However, we are not talking about something “normal.” Aemet’s forecasts temperatures above of the expected. That is, not only winter is over, but we are installed in a perpetual November. What does the prognosis about this week say? To begin with, he says that the last week of February “it will probably be warmer than normal in most of Spain, especially in the north and east of the peninsula.” Balearic Islands will be the exception. It is important to keep in mind that the situation will not be as tempered as in the previous week and that can distort our perception over it; But if we go to the data, it will be warmer than it should be the last week of February. It will rain in some areas (especially at the northern end of the peninsula), but they will not have a great entity. And, as it begins to be tradition, it does not seem likely to reach the southwest. And the next two weeks? According to Aemetthe trend “The most likely scenario for the following two weeks shows temperatures higher than normal for the time of year in practically the entire country.” Precipitation is more difficult to determine, but everything seems to indicate that “during the week of March 3 to 9, the storms will circulate through latitudes superior to ours and that the most abundant rains are limited to the northwest end of the peninsula.” To what extent can we trust this? This type of long -term forecasts are not as precious, valid and reliable as we do a week seen. And they are not because the weather pieces are not on the table and we cannot simulate how they will move in the next few days. However, our ability to determine trends has improved a lot in recent years and consistently these predictions have been useful for preparing for the future. What really matters. The problem, however, is not in what happens these three weeks. The problem is that, As they pointed from Meteotetuán“the trend is maintained.” A trend that will push large areas of the country to reunite with drought. In Catalonia, in fact, the situation is already very complicated (Sau’s swamp, in the heart of the Ter-Llobregat system is below 6%) and, in Andalusia, there is no good news either. Not only that Málaga You have not managed to recover from drought; It is that in areas like Córdoba the situation has caused garlic production to move (In 83%) to other areas of the country. May the trend be maintained, right now, it is a bad news.

There are 90 dolphins stranded on a remote beach in Australia with a marked end. Wednesday will be sacrificed to shooting

by

In recent years we have seen a lot of stories with dragged sea creatures by the sea until incompatible zones or habitatsoften because of the effects of temperatures changes in the oceans. However, few, or possibly none, such as the story that is taking place in a remote area of ​​Australia. Even there came more than a hundred dolphins, and most are still alive, but their end seems marked. Euthanasia. On a remote beach of the Australian island of Tasmania, 157 dolphins were stranded last week. However, environmental authorities have made the difficult decision of Start Euthanasia by shooting at 90 copies on Wednesday They still survived. The cause? Apparently, The impossibility of successfully returning them to the sea. The main reason for this decision is based on the fact that animals are increasingly stressed, severely affected by extreme environmental conditions, such as constant exposure to the sun and strong winds. Shelley Graham, in charge of managing the incident, has confirmed that, after exhaustive veterinary evaluations, Euthanasia is the only viable alternative to relieve the suffering of animals. A very difficult rescue. Experts have that the location in which the dolphins were trapped is particularly complicated for rescue work. Kris Carlyon, Marino Biologist, assured the media that it was one of the most complex sites with which it had been found In his 16 years working in Tasmania. The remote beach, located near the mouth of the Arthur River on the west coast of Tasmania, does not have easy access, which greatly complicates rescue efforts. Last week he tried repeatedly to refloat surviving animals, but without success. The physical characteristics of these dolphinsthat can weigh more than a ton and measure up to six meters in length, make it difficult to return them to the water, since it implies significant risks for both animals and rescuers. False calderones dolphins. The stranded dolphins have been identified as members of a little studied species popularly known as “false orcas” or “false calderones”named for the shape of their skulls that resemble those of the royal orcs. They are highly social marine mammals, accustomed to forming large groups that often exceed 50 copies. Not just that. This strong social bond implies that, when a single individual in the group is disoriented or trapped on the coast, it is capable of drag the rest of the group towards the same destination, causing massive variations Like the current one. These events are not unusual in Australia, but it is the first time in 50 years that such a significant one occurs in this specific area of ​​Tasmania. The science behind these cases. Although these incidents are relatively frequent in the region, scientists still do not know the exact causes that lead these creatures to vary in mass. According to the scientist Marina Vanessa Pirotta, from the moment a cetacean is caught on the beach, A critical countdown to its survival begins. Tasmania in particular is known as an area especially prone to variations, which could be due to its specific geographical location, complex for the natural navigation of these species. However, the ultimate cause of these incidents remains a mystery. Experts like Carlyon recognize that on many occasions The exact reason is never established whereby these animals reach the beach, and the explanation is usually reduced to collective behavior and group orientation. Ecological Impact. It is the last of the legs to be treated, the lack of deep knowledge about these dolphins makes the situation even more dramatic. According to information from the Australian government, There are no reliable estimates about the total number of specimens of this species in the wild. The species is classified in Australia as “almost threatened”, which underlines the ecological importance of this incident and the severity of losing so many specimens simultaneously. Plus: the death of large groups in incidents such as this has the potential of negatively impact the global population of the speciesespecially considering your relative shortage and the few data available on your state of conservation. Euthanasia in cetaceans. Finally, the euthanasia process in large specimens like these dolphins is not easy. In this regard, Kris Carlyon clarified that Mass euthanasias of large cetaceans are extremely complicated operationspractices that require precise and personal methods highly trained to minimize animal suffering. In fact, the choice of euthanasia through shots responds to a technical evaluation that considers the speed, effectiveness and lower stress in the execution. A procedure that in most cases It is usually a last resortapplied when there is no other reasonable alternative to save the life of animals. That said, the incident emphasizes the vulnerability of some marine species in the face of little understood natural and anthropogenic phenomena.

Someone has stolen $ 1.5 billion in a cryptocurrency market. It is the greatest crypto hacking in history

by

The cryptocurrency market had been encouraged again months ago. Everything seemed relatively quiet, but two serious events in this segment have brought us again those sensations of distrust and insecurity. And it will not be easy to get rid of them. A historical theft. Last Friday someone managed to hack the market for the sale of BYBIT cryptodivisas. The firm He quickly warned how they had detected “unauthorized activity” in their systems. It was the greatest cryptocurrency hacking in history: it is estimated that the attackers (s) managed to steal $ 1.5 billion in the form of ETH. The previous most important robberies had been the 470 million dollars stolen in the Mt Gox hacking In 2014, the 530 million coincheck In 2018 or 650 million from Exploit Ronin Bridge In 2022. Lazarus group as suspicious. At the moment the firm does not know how the hacking was performed, but apparently the company’s laptops were not compromised and the problem affected Safe, the “cold” purse of the platform. Cybersecurity consultant Arkham Intelligence indicates that Lazarus Group had been responsible, a statement based on The investigation of the expert in this area Zachxbt. Bybit says to be covered. Ben Zhou, CEO of Bybit, highlighted How his criptomoned sale market had enough reserves to cover hacking and cryptocurrency withdrawal – especially, especially, Stablecoins– Although for a few hours They blocked some functions of their purses to guarantee their safety. A few hours ago Zhou indicated how they had managed to cover virtually all funds. Panic in Bybit. The theft has caused many users to withdraw funds in Bybit for fear that these funds will also end up being stolen. As indicated In Coindeskin the hours following the HACKEO Bybit he saw how their clients withdrew 4,000 million dollars in funds. Of the 16.9 billion dollars managed in crypto assets in Bybit, the firm went to manage 11.2 billion dollars According to defillama data. Can Ctrl-Z do to the block chain? Some users asked if it would be feasible to make a kind of “roll-back” of the Ethereum block chain. That would allow us to undo the changes made by hackers and return the status of that great book of accounts to how it was before hacking, but it is not clear that this is possible. Experts indicate according to Coindesk that something like this would be possible, but the interactions between the Smart Contracts and their internal architecture make it not easy. It would be necessary to reach a consensus, and could even cause a division of the Ethereum block chain in two. Just when in the US the thing was encouraged. The robbery occurred just the day Coinbase had managed to reach an agreement with the United States Securities and Exchange Commission leave the demand without also being issued. Donald Trump’s re -election had promoted the value of cryptocurrencies, but since his appointment we have lived several worrying events. Memecoins, Trump and Milei. The scandals have been especially primed with the Memecoins created or supported by Trump and especially by Javier MileiPresident of Argentina. Both grew in a brilliant value and then collapsed in a mysterious and disturbing way, which points to possible fraud in which a few privileged were winning while hundreds of thousands of people lost their investments in these cryptodivisas. Distrust and insecurity, the eternal condemnation of crypts. The scandals with these memecoins and the spectacular bykit hacking return us the constant feeling of insecurity and distrust that the cryptodivisas have always generated. The institutional interest and a certain tranquility in recent times seemed to have softened that environment, but these new events will probably make more people think twice before investing in this type of assets. It is a bad idea to leave your cryptocurrencies in an “Exchange”. The truth is that these robberies have confirmed that their security measures can end up being insufficient to protect their customers’ funds. The most recommended form of experts to save these cryptocurrencies is do it in physical pursesdo not leave them in the purchase market for sale of cryptocurrencies (“Exchange”).

The iPhone 17 point to one of the greatest redesign in their history. One that shouts “android” to the four winds

by

When the river sounds, water carries, and in the world of phone leaks it is a standard that is usually met. A few weeks ago, Jon Prosser revealed The alleged design of the iPhone 17 Air and iPhone 17 Pro. Two telephone that would arrive, according to the filter, with a redesigned chamber module and that, everything is said, reminds some family models little of Xiaomi. A week later, new information based on Factory CAD supposedin which it is confirmed that the design, at least in this initial stage of product development. The iPhone carry without a remarkable design change from the family iPhone 11at least in relation to the camera modules. There have been dances in the respective to the position of the cameras and their size, but the rear remained unchanged since the year. iPhone 11 Pro | iPhone 16 Pro This design, which seemed immovable, would be about to change in the next generation iPhone 17. In this, regardless of the number of cameras, the module will be the main differential feature for the design of the new product line. iPhone 16 Pro according to Prosser and Majin Bu iPhone 17 Pro. Image: SonnyDickson All leaks are aligning in one direction: that of the iPhone 17 with a redesigned camera module and with a larger volume. According to leaks of alleged covers for this phone, with them the design will barely mean a change. Without it, the cameras will cease to be the only element that protrudes, to become part of a gigantic island … in the Android style. Xiaomi little x6 pro. One of the points we have criticized for 2024 has been the unnecessary of oversizing the camera modules to give them prominence. If the leaks are fulfilled, Apple will do exactly the same. Samsung was one of the few companies that had not joined the fashion with Apple, with a clean rear in which only the cameras stood out (as is inevitable). Another curious movement that is rumored is the return to aluminum throughout the iPhone 17 family, reserving the titanium frame for the iPhone 17 Air. This rumor is not yet solid and would be quite difficult to justify, given the good results (especially in weight reduction). This Apple’s decision would make a certain meaning: unifying the design of the family, regardless of the model we buy. Similarly, it will allow the iPhone 17 Air, who will allegedly land with just a camera, shine with some packaging despite having such a scarce photographic section.

Because the platform has already informed everyone of the changes that there will be for those who They kept the discount at the time of go from HBO Max to Maxand they are a bit bittersweet news. The first thing you should know is that The 50% discount is maintained. It should be remembered that this discount was for those who hired HBO Max on his arrival in Spain, and that the platform promised to maintain it. He then became Max, and said the discount would remain temporarily. Now we know that, despite maintaining it, there are changes in the prices of these users. What changes are in the Max discount Those who went from HBO Max to Max with the 50%discount did so with a Legacy plan that maintained the characteristics of this platform. The discount is going to be maintained, but Legacy Plan users get the characteristics worse hired when passing to the standard plan. Come on, that users with the Legacy plan will have the standard plan, which is worse than they had. If you had a legacy plan you will lose the quality 4K and the HDRreturning to the FullHD and SDR qualities of those who prefer to pay less and have a basic image quality.

I have tried Apple Intelligence in Spanish. I am disappointed and excited in equal parts

by

The star function of iOS for 2025, Apple Intelligence, can already be tested In the beta for iOS developers 18.4. It is enough to install this latest version to activate the functions, and I have not wanted to miss the opportunity to try this AI thoroughly in the iPhone 16 Pro. Due to the EU regulatory framework, Apple has taken something longer to bring these functions to Spain, which were already present in the US. Despite this circumstance, the rest of the rivals have been implementing artificial intelligence functions in a deep way for more than a year. Apple is late, yes. The question now is whether or not it is worth waiting. In this analysis we consider that Apple Intelligence is taking its first steps and that what we have tried is a beta. Despite this, we have these recent years testing beta versions of other services (Gemini, Chatgpt), and we are clearly required. “Hey, here are Ia” The system will guide us through the new functions. The first point that is worth highlighting is one that I have been criticizing for quite some time in competition alternatives (except in Samsung, which makes it great). The AI ​​is of no use if the average user does not know where and how can he use it. Here Apple does it quite well since, from minute one, it sends us notifications indicating that Apple Intelligence is now available. I have no doubt that, like Samsung, when we start our next iPhone the configuration assistant will explain all this process that is now explained with notifications. Being a beta, some of these explanatory banners are in English. A minor detail, since everything is still working in Spanish. Given the notices and read everything, it’s time to start trying Apple Intelligence. The functions that arrive in Spain are practically all, with the exception of MACs to Mac and the transcription of calls. Testing Apple Intelligence Apple Intelligence is a set of artificial intelligence functions that arrive natively to the iPhone. Its main difference with respect to direct rivals is that the majority of the defendant is carried out on the telephone itself, the main reason why the model cannot be executed with less than 8 GB of RAM (and thanks to which the iPhone 16E It has this capacity). Among its functions we find new writing tools, image generation, integrated by chatgpt in Siri, Genmojis, and improvements in native apps such as photos or mail. Writing tools Apple stands out on its website The functions he considers key to Apple Intelligence. The first one has to do with intelligent writing tools. These allow us to rewrite texts, make summaries, improve the grammar and tone of what we have written, etc. Integration is great, since these tools work in any app. Simply select the text to appear. Here we will have two paths: describe the precise change we want to do through a personalized prompt, or let Apple do it automatically by predefined adjustments quite concrete. Review Rewrite Informal style Professional style Concise style Summary Key points List Board The functioning of these writing functions is quite good. I have reached the test by throwing an entire review to analyze key points and, although it is not perfect, it does it more than remarkable. These types of tools are especially useful in professional environments where we want to improve that email that we are going to send. Improvements in Siri Siri is one of the great changes in Apple Intelligence, with a much more pleasant interface, Integration with chatgpt And the promise that you can read everything we have on the screen to analyze its context and provide us with information. This last function, the most spectacular, is not yet available (not even in the US). In my case, I had to force from the “prefer voice responses” settings since, in automatic mode, I never spoke to me (only the written answer appeared). The operation of this new Siri, at least in its beta phase, It is disappointing. It highlights, in principle, to better understand natural language, but it is far from the memory we have seen in IAS as GPT. For example, I have asked you to add an event from 17 to 18h. Subsequently, I have indicated that I remind me what is the last event he added. His answer has been to add to reminders “the last event you have created today.” Indicating what event it was, I have asked him to modify the time. His answer has been not found. Siri is far from understanding natural language as GPT. At least in this first beta in Spanish On other occasions, he has not even answered my questions or has been frozen. The potential is there but, at least for now, it is a tool far away from what is expected. Regarding the integration with chatgpt, it works as an extension of Siri. We can log in or not and, in case you detect that GPT can attend to our request, it will invite us to use it. This is the key here, will only use GPT if we give permission. If we give GPT permission, the requests will be made through the OpenAI model, but with Siri’s voice. In other words, we will have the GPT responses read by Siri. This integration seems quite good to me, since it will allow mixing the best of Siri and its possibilities at the system level (putting alarms, reminders, adding events, sending emails, etc.) with the GPT potential. Native apps Photos. Apple wanted to add some functions in its native apps, starting with photos. One of the star functions is Clean Up, his rival for Google’s magic draft. And I can advance that it is not even approaching. Photograph of the gallery. Clean Up | Google Magic Draft Photos. First, automatic subject detection has only worked once. The rest, I had to manually select what I wanted to erase. As for the … Read more

The secrets of the port of Shanghai, the colossus of international trade where automation reigns

by

Check out around you. The screen you are looking at, the clothes you wear or even your coffee maker have probably crossed the ocean in a container before reaching you. It is not a simple random assumption. About 80% of the goods travel by boat, which makes maritime transport into the backbone of the World Trade. Without this machinery running precisely, getting many of the things we use every day would be little less than an odyssey. A key piece of this system is the sea ports. We are talking about the nerve centers that not only receive and dispatch millions of containers a year, but also coordinate a millimeter logistics that allows goods to circulate fluently between continents. It is no secret that this world is in constant movement, but there is a title that has not changed hands for a long time: the port of Shanghai has been the most active in the world for 14 years. The port of Shanghai is also a port megaciudad After a long time, In 2024 the port of Shanghai became In the first in the world to handle more than 50 million teu in a single year. And when we talk about TEU, we refer to the standard container unit of 20 feet (6.1 meters) long. This port did not begin its rise to the throne yesterday. One of his first great achievements occurred in 1994, when he first exceeded the million TEU. Since then, its performance has grown exponentially, multiplying by 50 in three decades. There is no doubt that this reality is directly related to China’s industrial muscle, which has established itself as The greatest manufacturing power in the worldand with the spirit of the Asian giant for developing ambitious works. The port of Shanghai has not stopped evolving during the last decades. Automated terminals have gained ground to improve efficiency and security drastically. Less people work and everything becomes much faster. The port has completely automated terminals where tasks such as goods discharge, stacking and output are controlled by the “brain” of the management system. Sun Jinyu, one of the leaders of the Shangdong terminal, had in 2021 that The cranes needed about 108 operators in the past, but automation had allowed the same tasks With only 7 operators. And, because of that was not enough, most of the work was done through remote operation. But an impressive infrastructure would not be enough without strategic ties. The port of Shanghai began to handle containers in the 1970s and it was not until 1978 that he opened his first international route, one that joined China with Australia. At present, it is linked to almost 350 international routes, connecting more than 700 ports in more than 200 countries and regions of the world. Internal level, it also has 22 ports distributed by various Chinese provinces, consolidating its role as a key node in global trade.

The Atlantic has a ‘lost city’ with the key to life on other planets. Now is in danger

by

The earth seems to have no secrets at this point. That if we talk about the earth’s part, of course, because although nWe are putting the batteries With the oceanic background, much remains to be known. And one of the examples is the lost city found in 2000, a set of structures in the middle of the Atlantic that are not only curious, but they help us with the most unexpected: Study extraterrestrial ecosystems. And, ultimately, determine the clues that must be followed to find life in the universe. Only. More than 700 meters deep west of the Mesoatlantic dorsalon December 4, 2000, some explorers in command of remote control submersibles found something surprising: a set of walls and monoliths that reached 60 meters high and had a curious bluish tone due to the foci of the submarines. These carbonated structures were something that the scientific community had never seen and was baptized as the ‘lost city’. Among that we love giving rimbombant names and that could resemble Atlantis, the marketing part was already made. Chimneys. The full name is, really, ‘Hydrothermal field of the lost city’, and it is the oldest oceanic ventilation site, at least what we know. It is estimated that he is about 120,000 years old and, during all that time, his chimneys have been expelling gases at temperatures between 40 and 90 degrees Celsius. These hydrothermal vents release methane and hydrogen, but are not volcanic, so they do not produce co₂, hydrogen sulfide or metals. With the passage of the millennia, that expelled material was accumulated in the form of columns and walls of Brucita, Aragonito and Carbonate of calcium, with a whitish color and very particular schegic texture. Point of interest. For the scientific community, the lost city is a mine. Its particular environment and the conditions of its formation, as well as its age, can provide clues about the origin of life on Earth, as well as a more detailed vision of the planet’s composition. Over the years they have been studying their materials and, in 2024, a group of scientists advertisement The recovery of a rock sample more than a meter long. With her, they hope to find crucial evidence about the origin of life on earth. There are some spectacular formations. Researchers at the University of Washington described some vents as structures that “cry” fluids that form carbonated structures of multiple tips as curious as the one we see in the photo that we leave just on these lines. But there are not only rocks in the lost city. Extraterrestrials. At that depth, without oxygen, with a highly alkaline and hydrogen, methane and other gases dissolved in water, we might think that it is a ‘lunar’ ecosystem in which life is impossible. Curiously, It is full of animals such as anemones, microbial communities, crustaceans, snails and, occasionally, deep fish. The question is how life can prosper when it comes to an environment in which there is no sunlight, there is no oxygen and both hydrogen and methane, they camp their wide. That is precisely what also called the attention Of the researchers because the study of this fact can give us clues about what kind of life or signs of life to look for in environments that can be similar, such as redry or Europe (Saturn and Jupiter moons). Threatened heritage. Writing this has given me to think about ‘Avatar‘Not only because the film has attractive extraterrestrial structures, but because its director, James Cameron, is a passionate about underwater expeditions. And something that happens in his film is that we arrive at another planet and sweep it to get resources. We must not go to Pandora -the planet of ‘avatar’-, we continue to see it in areas such as the Amazon. And that we destroy the lost city is something that researchers fear. Poland got In 2018, the exploitation rights of the seabed around the lost city and, although the hydrothermal field has no valuable resources for us, altering its surroundings could endanger the entire area. That’s why you are working so that the lost city is declared a World Heritage Site with the aim of protecting it as much as possible and being able to continue studying it. We will see what happens with an area that is not the only hydrothermal field in the world, but one whose particularities can help understand how life develops in extreme conditions and in similar extraterrestrial environments.
