We have been knowing where a strange sound has been coming from. Now he has returned strongly to an island of Scotland

There are phenomena that challenge not only reason, but even perception same of reality. One of them is remembered in Scotland Since the end of the 90s, a low frequency buzz that is heard in different parts of the world and that, although for the majority it goes unnoticed, for those who perceive it is as real as it is unbearable. The buzz has been called The Humand on a Scottish island it seems that it has returned strongly. Breaking calm. In the apart Lewis Islandin the Scottish archipelago of the Hebrides, a persistent and strange low frequency hum has begun to disturb the life of its inhabitants, generating confusion, anxiety and health problems among those who claim to listen to it every night. It is a serious, pulsating and penetrating murmur, which prevents the sleep and causes vertigo, headaches and even alterations of concentration, according to testimonies collected by the British media. Despite its intensity for those affected, the phenomenon lacks a clear source and remains out of the reach of consensual explanations. The person responsible for documenting this disturbing anomaly is Lauren-Face Kirtley, founder of the support group “The Hebridean Hum”which has compiled dozens of complaints citizens and acoustic records in different areas of the island, in which a persistent signal of about 50 Hzvariable in intensity, but present in all cases. This data has allowed to rule out local sources such as port infrastructures, wind turbines or industrial facilities, and has redirected the search towards a possible origin … marine. Between the physical and the perceptual. Although some members of the group have considered physiological hypotheses such as otacoustic emissions (Sounds generated in the inner ear), the geographical disparity of the experience weakens this line of explanation. Pamela Weaver Larson, one of the group’s participants, said Do not listen to the buzz When he moves outside the island, which would indicate a Located environmental source more than a subjective phenomenon. This contradiction reveals the complexity of the case, which is registered in a much broader pattern: the call “Worldwide hum”an acoustic phenomenon documented for decades in various regions of the world, whose causes remain enigmatic and their simple existence remains questioned by scientific sectors. Glen Macpherson, founder of the World Hum Map and Database Projecthas compiled hundreds of testimonies that describe a buzz similar to the engine of a parked vehicle, more noticeable at night and in closed spaces, although generally described as omnipresent. The Hum, the beginning. As we said at the beginning, at the end of the 1990s Scotland began to perceive these hum. This was lived by Georgie Helop, a Scottish woman who after the death of her husband moved to the coastal town of Largswest of Glasgow, looking for peace of mind. What he found was the beginning of a sound nightmare: a constant buzzserious, similar to that of a truck in idle, which seemed to have no visible source and that was even more intense inside his own home. It wasn’t just an annoying noise. With the passage of time, the phenomenon began to cause physical ailments: headache, nasal hemorrhages, ear pain, chest oppression. As a desperate measure, Helop came to sleep in a tent in the garden, looking for peace that he did not find inside the house. Your case It was not isolated: Over time he discovered that not only in Largs, but in other parts of the United Kingdom, the United States and the world, many other people also reported to hear the same inexplicable buzz. Bewilderment. So and look back, Since 1973 similar cases have been documented in Very different towns: Taos In New MexicoHueytown in Alabama, Rome in the seventies, Bristol board In the United Kingdom. In many of these places, only a small fraction of the population, often middle -aged womendeclares to listen to the noise, which has led to multiple speculation about its origin. Some theories point to Physiological conditions as Tinnitusa sound perception without external stimulus. In the 1990s, hearing experts suggested that those who heard the buzz simply did not accept their clinical diagnosis. But over time, and thanks to the advancement of technology, some scientists have managed to detect real emissions, of such low frequencies Like those 50 or 60 hertziosand even others higher in the range of the Megahertzios, which has opened the door to explanations that go beyond the inner ear. Another explanation. Some hypotheses point to Combined frequencies which generate a kind of “milkshake” only perceptible to a minority with extreme acoustic sensitivity. Others suggest that the buzz originates in modern infrastructure (telecommunication towers, wind turbines, gas pipelines, military facilities), or even in electromagnetic or acoustic phenomena not yet understood. Project map started by Macpherson The map of an invisible sound. As we said, in 2012 a Canadian professor named Glen Macpherson began to listen to the buzz in his home in Sechelt, in the British Columbia. His personal experience led him to found the World Hum Map and Database Project, a collaborative platform where affected people can Register your location and share your experiences. Over the years they had already been reported More than 5,000 points of the planet where it was claimed to hear the buzz. The project has contributed to visible an experience that for decades was discredited or attributed to psychological causes. In the case of Helop, scientists who analyzed their home could Register anomal frequenciesconfirming at least partially that something physical happened in that environment. New explanations. Like those with the most recent cases, one of the explanations that has gained more strength associates the phenomenon with the geography of coastal areas. Largs, like many other points where the buzz is recorded, is located near the ocean. According to This theory exposed at the time In the Washington Poststorms in the sea generate waves whose impact is transmitted to the ocean bed, causing vibrations that extend through the earth’s crust. These oscillations could travel at great distances and be detected by those with … Read more

In the coming months, Jaén will control the world marketing of olive oil. It won’t help him

While I write these lines, according to the data of the Ministry of Agriculture, there are 773,596 tons of oil in the country’s oil mills. Practically half, they are in Jaén. There is more oil in the Jienenses oil mills than those that all industrialists, packagers and refiners have. A lot more. Almost double. That is what turns Jaén into the gravitational center around which the entire international olive oil industry is going to turn. The big question is if he will know how to take advantage of it. We’re So Back. Let’s do A quick review. After a pair of nightmare years, at the end of March, the Jiennese wineries accumulated about 369,245 tons. That placed it (with a lot) as the main producer of the world. Córdoba follows (with 135,865 tons) and Granada (with 74,124). And a little further back are Seville (44,158) and Malaga (13,590). Castilla – La Mancha adds about 81,700 and Extremadura still has about 27,000. There are, if the figures are fine, reserves of 773,593 tons until the oil of the next season arrives. And we are selling it very fast. As we said a few days ago, According to data from the Information and Food Control Agencyonly in March, “135,000 tons have been marketed (including imports) to an average of 3.62 euros in all categories.” That is, we are selling oil at a rate that is not sustainable: that it will not reach us until the next campaign. It is not a problem for consumption because everyone knows that the boom of sales and low prices (which are causing losses of more than 270 million euros in the sector) is due to a concatenation of problems and circumstances: The commercial chaos of American tariffsthe delicate financial situation of the producers and the expectations that the price can continue to fall (for the rains). The situation is problematic because it does not allow companies to clean up their accounts, but cannot be sustained too much in time. And then? That is the big question. Because, as we see that it has happened in the banana, the Spanish countryside is getting used to passing one problem to the other without any transition period. Given this scenario, most Great challenges of the olive grove They remain in the air. And it begins to be A bad time not to make the right decisions.

The kindness with chatgpt is coming out of OpenAi. The “please” and “thanks” have an absurd cost every month

Probably these days, doing Scroll In social networks, you have crossed with one of those memes that say everything with an image: a man about to be eliminated by robots is saved at the last moment because, according to one of them, he “always said thanks.” A minimum, almost automatic gesture, which redeems it to machines in the dystopic future and that starts a smile in the meantime algorithm. Obviously, we do not expect robots to take control of the planet. But it is no accident that this idea has become viral. Cinema and literature have been feeding that imaginary between fascination and fear. The funny thing is that, beyond fiction, there is something real in all this: being educated with artificial intelligence (AI) is not free. Our kindness, however routine, costs money. And not precisely little. The functioning of AI is not exactly cheap. When we use an artificial intelligence chatbot, we rarely think about the consumption of resources that each of our requests implies. Chatgpt and other similar systems work thanks to large language models, also known as LLM, which operate in data centers equipped with high performance hardware, such as NVIDIA H100 GPU. The execution of these models, which is technically called inference, requires enormous processing capacity and, therefore, a considerable amount of electricity. To all this we must add the necessary investment to build and maintain these infrastructure, as well as their environmental impact. We know, for example, that many of these centers consume large volumes of water to cool the systems, since this type of computer generates heat. Very hot. There is no consensus on how much each request costs, and the figures vary according to the company. Even so, Sam Altman has given a track. The amazing cost of kindness. A few days ago, a user asked on social networks how much money Openai would have lost just because people add “please” and “thank you” to interact with their models. CEO’s response did not go unnoticed: “Dozens of millions of dollars well spent.” He did not speak of a single interaction, of course, but about the accumulation of millions of friendly messages over time. Click to see the original message in x It is curious that, despite the high energy and economic cost that this represents, Altman considers that it is a justified expense. Should we be kind to an AI? As in any other area, there are people who prefer to go directly to the point and others who choose to maintain a more careful and educated tone. This difference probably also has to do with the way each one communicates in their day to day. And in this context, kindness is not just a matter of manners. A study entitled “Should We respect LLMS? A Cross-Linguistic Study of Prompt Politeness in Academic Performance”Analyzed the role of courtesy in the indications and left some interesting conclusions. Among them, that unfortunate messages tend to generate a worse performance. Although, yes, excess courtesy does not guarantee better results. What seems clear to those who use this type of chatbots daily, and more now that they are able to learn and remember more precision, they can adapt to the user’s tone. If we want a more respectful, more coherent and a little more human interaction, we should probably start by taking that step.

The new OpenAi image generator takes a 180º turn in a section that we did not see coming: censorship

That of the photo is supposed to be that of Karl Marx with purchase bags and with an unusual attitude: leaving a shopping center and demonstrating An unusual change to capitalist and consumerist philosophy. But of course, it is not him: he is a Deepfake generated by a very peculiar model. Specifically, by the new OpenAi model integrated in Chatgpt and that goes beyond Dall-e in a key apparent: censorship. Goodbye (almost) to censorship. In the “system card“From this OpenAi model, a unique message stands out: we can generate deepfakes without apparent problems. As explained in that text, “The generation of images 4 is able, in many cases, to generate a representation of a public figure based only on an indication of text. In this launch, We will not block the ability to generate adult public figuresbut we will implement the same safeguards that we have implemented for the edition of images of photorealist loads of people. For example, this includes trying to block the generation of photorealist images of public figures that are minor and material that violates our policies related to violence, images that encourage hate, instructions for illegal activities, erotic content and other areas. Public characters who wish not to generate their image can choose not to participate. “ A similar approach to Grok’s. Openai’s philosophy is now The same line than the one Grok 3 raised With its generation of images months ago. Censorship disappeared and it was feasible to generate any type of Deepfake even with public characters. Openai responsible highlight how the approach here is different from the series of Dall-E models, and that “opens the possibility of useful and beneficial uses in areas such as educational, historical, satirical and political discourse.” Even so, they add, they will continue “monitoring the use of this capacity, evaluating our policies, and we will adjust them if necessary”, which makes it clear that a misuse of these options could lead OpenAi to re -apply censorship mechanisms. Why now. Openai’s decision is striking, but logical. Grok 3, which was a little widespread model, has achieved some popularity thanks to that “politically incorrect” approach to its AI model. After all, AI models are tools, and can be used for both good and evil, like any other tool. Controlling the bad uses is extremely difficult and expensive, and here OpenAi leaves the ball on the roof of the users. The Deepfake generation With famous characters in Grok 3, he unleashed a flood of memes and contents of all kinds with those celebrities, but it seems that in recent times “we have become accustomed” to having that capacity and apparently the diffusion of these images has relaxed. The initial controversy has blurred, and Openai probably knows that this will help further boost the use of chatgpt and perhaps to harm his rival, Grok 3. The quality of the photorealist images rises of level in this new image generator integrated in chatgpt with GPT-4O. Source: OpenAi. But they don’t want to put the leg. Generating images is wonderful, but it can also end up being a problem for the models that put the leg. It happened to Google with Gemini, which ended up generating controversial images of Black Nazis soldiers in which the desire to be inclusive ended up posing reputational problems and Important economic. He Addendum to the official announcement by OpenAI Let it clear They have taken special care to generate “safe” images. The model censures much less, but can continue to be refused to generate certain types of images that, for example, avoid control of CSAM materials (sexual Child abuse material). The evolution of Dall-e. In January 2021, nobody probably paid too much attention to a news that we published in Xataka. An unknown OpenAi Dall-e presented at that timea model capable of generating images from a text prompt. In April 2022 Dall-e 2 would arrivebut in reality we all “click” in June of that year, when it was launched Dall-e 2 mini And we could all try that. And it was impressive. Images in Chatgpt. The new OpenAi in this area is not a theoretical Dall-E 4. instead what the company has presented is the so-called image generation integrated in its model GPT-4O. The announcement is important because it allows you to generate images directly within Chatgpt, but also do it with a quality clearly superior to that offered by Dall-E. Until the text generates well. One of the outstanding characteristics of this model is its ability to render text precisely: if you ask for an image with a certain text, that text will appear clearly, while in other models the text may appear distorted or illegible. According to Openai, the model takes advantage of “the inherent knowledge base of 4”. And more striking options. In Openai they also highlight how we also have the ability to generate in “multiturn”, that is, refine images from the previous ones. We can polish them or add new elements to the images with new PROMPTS. The understanding of the context, the quality of the photorealistic images – such as Marx – or even the generation of diagrams and graphs are other remarkable options of this image generation model. Activated water marks. There is an additional element of the model: all the images generated They include C2PA metadatathat is: they contain invisible “water marks” that allow to identify all these images as generated by GPT-4O. In Openai they even emphasize that they have created an internal search tool that allows us to use the technical attributes of the generations to verify if that content comes from their model. But it is still imperfect. The company’s own ones notice: the images may contain bulk and hallucinar errors, and the generation of text, especially with multi -mounted support, can end up offering meaningless texts. Who can use it. The image generation in 4o has already begun its deployment for users of Chatgpt plusPro, Team and even free accounts, and will soon reach Enterprise … Read more

The war between the Azores anticyclone and Iceland depression will have a clear winner in the coming weeks: Spain

If there is any field in which what was said by the famous physicist Niels Bohr that “it is difficult to make predictions, especially of the future“That is meteorology. Although it is not always the case. There are times that, with all the uncertainties we want, “we see them come long before normal.” And that is what just happened: the main prediction models in the world They say we are going to a negative nao stage. Something that, in the face of spring, can be excellent news. What is NAO? ‘Nao’ are the acronym in English of ‘North Atlantic oscillation‘And basically refers to the’ dance ‘between the Azores anticyclone and the loss of Iceland, the two great atmospheric phenomena that govern the meteorology of the North Atlantic. When the index we use to “measure who is winning” is negative, the anticyclone of the Azores is weaker than normal and, therefore, cannot block the deep storms of the Atlantic. The direct consequence is that, they circulate further than normal: in our latitudes. Kristian Strommen et als. (2021) The news is that, indeed, it seems that we are going to Noa negative. Both the NOAA American and the European ECMWF They coincide in which “we are at the gates of a Nao phase in descent.” And what consequences would this have? The combination of a negative nao and a large mass of stagnant polar air in the continent would cause the circulation of deep storms to pass us over and, therefore, the weather conditions are stirred. A summary of the situation. In the short term, we are in the midst of that cyclogenesis festival that we have already talked about, but when the stability will be installed again. That means that nocturnal temperatures will lower, the frost will return and the fog will return. From then on, if the NOA phase change is confirmed, the situation becomes difficult to predict. The good part of this type of diagnoses is that it is very solid (that is, it is quite likely to pass); The bad is that the details become more complex: it can be triggered from a sudden stratospheric warming that froze everything that caught its path to almost nothing. It is reasonable to wait for rain in one way (deep storms) or another (retrograde danas), however the prognosis is in the air.

All the AI ​​functions coming to the Galaxy S25

After months of waiting and endless leaks, the Samsung Galaxy S25 They are now official, and come with new features in terms of design, power or cameras, with new colors, a more advanced processor and new sensors to improve photographic results. The new members of the Galaxy family also come with a handful of AI features aimed at improving productivity as well as image editing, and some of them are really interesting. Some of these artificial intelligence features that include the Galaxy S25, Galaxy S25+ and Galaxy S25 Ultra, however, already debuted with the Galaxy S24, and in the new models they continue to be free. One of them is Circle to Searchwhich allows you to circle an area of ​​the screen to get information about what it is showing. It also maintains the instant translator on calls or audio notes transcriptionthe summaries in the notes app and more. Another of the AI ​​functions that the Galaxy S25 maintains is the integration with GeminiGoogle’s language model that competes with ChatGPT. In the new smartphones, yes, the integration with Gemini goes one step further. Samsung has added additional functions to interact more quickly with the assistant, such as a specific Gemini button when the user takes a screenshot, so that the AI ​​shows information about it. The AI ​​news coming to the Galaxy S25: improvements in Gemini, new summaries and more In addition to this, the Galaxy S25 has a More conversational AI that is capable of answering more specific or advanced questions. For example, users can ask the assistant to show images from the trip to Italy, and it will do so. On the other hand, the Galaxy S25 arrives with more integrated AI across platforms. Samsung and Google have collaborated to make their services and applications work together, which will allow users, for example, to ask Gemini to show the agenda that has arrived in the Gmail email and add it to the Gmail calendar application. Samsung. At the moment, however, it is not clear how integrated this function will be in third-party platforms and services, beyond Google and Samsung, although the company has confirmed that it will be compatible with popular apps, such as WhatsApp or Spotify. And of course, there are new AI features. One of them is AI Selectwhich can interpret the context of what the user is doing and suggest specific actions, such as making a GIF if you are watching a video The other new function is Now Briefa kind of assistant that is capable of making summaries of the most important things from time to time. The user can configure this function so that, for example, it gives a summary of the weather every week, sleep every morning, etc. Now Brief can also learn from your habits and give you summaries based on your location (for example, if you go on a trip, at the end of the day it can show you the photos you’ve taken) or whether you perform a specific task each day. Finally, Samsung has added to the Galaxy S25 Now Bar, a kind of iPhone Lives Activities that shows relevant information about a specific application on the lock screen, for example, the time left on an order, etc. AI functions applied to the camera The Galaxy S25 camera also improves thanks to AI, and specifically thanks to these functions that Samsung has included in its smartphones. Related to the edition, we find the audio eraserwhich allows you to eliminate unwanted sounds in a video and even select the type of noise we want to eliminate (traffic, wind, etc.). In any case, there are other AI functions that Samsung has added to improve photographic results, including a mode that takes screenshots before and after the original image, so that the user, if the photo turns out wrong, can choose another face. And, of course, the magic eraser for photos It remains the same, although the company has improved it and is now more precise. Samsung also confirms that most of these models work locally, so they can even be used without an internet connection and in a more secure way.

These are Samsung’s augmented reality glasses. Project Moohan is coming, and it will be governed by Android XR

The celebration of Samsung Unpacked 2025 has provided not one, but two surprises. The first, the fleeting presentation of the Samsung Galaxy S25 Edgethe ultra-thin mobile that we were able to see in the exhibition area after the event. The second, the augmented reality glasses that Samsung has been developing for some time. They are the result of Project Moohan that Samsung spoke briefly about at the event, and that will precisely compete with devices like the Apple Vision Pro or the striking Orion of Meta. The design of the glasses is in fact very similar to that of Apple’s glasses, although it also has certain design lines apparently inherited from the Meta Quest Pronow discontinued. During the presentation, Samsung mentioned its intention to bring AI options to other form factors such as connected glasses – Ray-Ban Meta type, we imagine – and augmented reality glasses. Samsung actually announced that it was working on augmented reality glasses in collaboration with Google. That is the goal of Project Moohan, who also stands out for be governed by Android XR. This operating system will be a competitor to visionOS, Apple’s proposal in the Vision Pro. At the moment the augmented reality glasses could be seen on display and we were able to photograph them, but there are no more details about them: we have to wait. In Xataka | Mark Zuckerberg believes that in 2030 we will not take our smartphones out of our pockets so much: we will do almost everything from our glasses
