OpenAI wanted to make ChatGPT the ideal GP. The problem is that he’s wrong half the time.

by

OpenAI started the year with a new release: ChatGPT health mode. Although it is not currently available in Spain, it is in the US and the first studies are already appearing that test its effectiveness and they are not very good news for OpenAI. It’s not that big of a deal. A recent study published in the journal Nature Medicine and collected by NBCNews has revealed that ChatGPT Health failed to classify the urgency of 51.6% of the emergency medical cases analyzed. The researchers presented thousands of clinical scenarios to the model and saw that the AI ​​tended to undervalue critical situations, suggesting that the patient visit the doctor in 24-48 hours when, in reality, these were emergencies that required rapid intervention such as diabetic ketoacidosis or respiratory failure. It did correctly classify other cases as stroke or severe allergic reactions. It doesn’t make sense. Not only did it underestimate serious cases, cases of mild symptoms were also provided and ChatGPT Health overrated 64.8%, urging the patient to see a doctor as soon as possible, for example in cases of persistent sore throat. Dr. Ashwin Ramaswamy, leader of the study, told NBC that “it doesn’t make sense that recommendations were made in some areas and not in others.” Suicidal ideas. There is still more. The cases presented included some with suicidal ideations. One of these cases was a patient who showed interest in “taking a lot of pills.” If the patient only described their symptoms, a banner appeared with the suicide prevention help number. However, when the patient added the results of an analysis to their query, ChatGPT no longer detected suicidal ideations and did not display the banner. According to Ramaswamy, “A crisis protection barrier that depends on whether lab results are mentioned is not in place, and is arguably more dangerous than having no barrier at all.” Why it is important. The relevance of this finding lies in the fact that ChatGPT has become the frontline doctor for many people. The ease of checking symptoms from a mobile phone is displacing traditional methods of consultation; What we used to Google, we now ask a chatbot. If the main tool that people use to decide whether or not to go to the emergency room has a 50% margin of error in serious cases, we have a problem. In statements to GuardianAlex Ruani, a researcher in medical misinformation, described these results as “incredibly dangerous” and notes that it creates a “false sense of security (…) If someone is told to wait 48 hours during an asthma attack or a diabetic crisis, that peace of mind could cost them their life.” OpenAI responds. A company spokesperson defended the accusations by saying that the study does not reflect typical use of ChatGPT Health, arguing that it is not designed to make diagnoses, but rather to answer follow-up questions and help patients get more context. At its launch, OpenAI insisted that the tool was not a substitute for a doctor, the problem is that once a tool like this is launched, how people use it is out of the company’s control. Flattery and hallucinations. Chatbots have a flattery problem and they tend to agree with the user. On the other hand there is the phenomenon of hallucinations. LLMs are designed to prioritize giving an answer over admitting that you don’t know something, and the worst thing is that you do it with such confidence that we believe it. It is not an empty statement, It has been proven that we feel safer using an AIeven when the answers it gives us are incorrect. If we mix adulation, hallucinations and health, we have a quite risky cocktail.

It is capable of compressing space and time

by

15 meters deep, in a basement of Zhejiang University, China has installed a machine the size of a building capable of doing something hitherto impossible for a laboratory: reproducing in hours what nature takes centuries to build. Or destroy. Its name is CHIEF1900 and it can rotate at extreme speeds or generate a gravitational force a thousand times greater than that of the Earth, which for example serves to simulate an earthquake and its effects. Context. For a geology professional, analyzing a portion of land means deciphering the history of the planet in layers: each stratum is a record of millions of years. The problem is that nature writes it slowly. Reproducing this phenomenon in a laboratory has been one of the great challenges of experimental physics for decades. Hypergravity centrifuges are the tool that comes closest to that goal. These machines are capable of rotating at extreme speeds, generating forces hundreds or thousands of times greater than Earth’s gravity. When rotating, the arms generate outward pressure on everything inside the machine. The faster it is, the greater the force. The result is a controlled hypergravity field that compresses time and distance. What China has achieved. Zhejiang University (Hangzhou) has completed the construction of the most powerful hypergravity centrifuge in the world: it will have a total capacity of 1,900g·ton, that is, it can apply 1,900G to a one-tonne sample. The CHIEF1900 will surpass the record that China had established a few months before (September 2025), with the CHIEF1300. This power makes it possible to replicate land deformations on a kilometer scale, simulate the transport of pollutants over millennia, evaluate the resistance of a dam to an earthquake or generate thousands of new material samples. As a reference, with the CHIEF1300 they have already been able to reproduce the pressure of the seabed at a depth of 2,000 meters to evaluate the extraction of methane hydrates, or simulate how a 20-meter tsunami affects the seabed. Why is it important. To natural disasters such as earthquakes or tsunamis we have to add other consequences of human activity such as the breaking of dams, contamination of aquifers or deformation of the soil under high-speed infrastructure or the melting of glaciers. Predicting how these phenomena will behave requires information that is not available since obtaining them in real conditions is either impossible or would take decades. Dan Wilson, deputy director of the Center for Geotechnical Modeling at the University of California, explains for Popular Mechanics that this will be one of the four largest dynamic centrifuges in the world, that is, it can simulate active earthquakes using hypergravity. Chen Yunmin, chief scientist of the project, sums it up accurately: It aims to create experimental environments spanning from milliseconds to tens of thousands of years, and from the atomic to the kilometer scale. How they have done it. To build a machine with such performance, Zhejiang University brought together a multidisciplinary team that brings together personnel specialized in civil engineering, thermodynamics or automation. Among the technical challenges they faced was heat: at high rotation speeds, the centrifuge reaches such temperatures that the stability of the system is compromised. The solution was a cooling system that combines vacuum, forced ventilation and glacial coolant. The fact that the installation is buried has an explanation: it minimizes external vibrations, which could contaminate the experiments to be carried out. Pending subjects. Although the installation dates back to the end of 2025 and Popular Mechanics mentions which is already operational, no scientific results from CHIEF1900 are yet available. At an operational level, these scale models reproduce the loads well but not always all the size effects: certain material behaviors do not scale linearly under hypergravity, which requires caution in the interpretation of results. To minimize this risk, it is common for the data obtained to be compared with that of other similar facilities around the world.

Is it a good time to buy a Samsung Galaxy S26 or will the price drop soon?

by

According to the price at which the Samsung Galaxy S26 And taking into account our trend analysis and market history, this is how we see the purchase of Samsung mobile phones right now: 🟢 Buy with confidence Samsung galaxy 26 (base) Verdict “Launch” moment. It is on pre-launch sale and you will enjoy the novelty for a few months. official RRP €999 (Samsung store). Target price “on the street” Don’t pay more than €949 for the base model. Next release Samsung Galaxy Z Flip and Z Fold (expected in 2026), Samsung Galaxy S27 (expected in February 2027). Our recommendation Buy keeping two things in mind: 256 GB model: on Amazon it is on sale with a coupon for €949. 512 GB model: on Amazon it is on sale with a discount + coupon for €944. Our recommendation right now is to buy the 512 GB model taking advantage of the double direct and coupon discount. Regret cost Low. The mobile phone has just been launched and is on sale, so you can enjoy the novelty for a lower price. Why is the traffic light GREEN? Right now (March 2026) we are in its pre-launch period, so we have the news of a new mobile phone along with the offers that we usually have on most of the brand’s smartphones in this period. Thus, we find ourselves in this situation: Pre-release effect: The Galaxy S26 has not been launched yet, so we can enjoy a few months of the “newness” effect. Multiple offers: The launch has been accompanied by many offers, which may vary depending on the store we look at. Prices in their configurations: One of the most attractive offers lies in the “Double your storage”, a campaign that many stores have in which we have the 512 GB version at the same (or similar) price as the 256 GB version. This also affects higher internal storage configurations. Expert buyer advice: If you are going to buy a Samsung Galaxy S26 right now, go for the 512 GB or 1 TB configuration if you want to have a lot of storage, especially in its pre- and post-launch period, which is when it usually has the best offers in the first months of the cycle. Price history and change prediction The image above is a price chart of the previous generation, the Samsung Galaxy S25 (2024-2025), and we have superimposed it with the prices that we have seen so far on the Samsung Galaxy S26. This is what we see: What history tells us: During the first months of the cycle we only usually find post-launch offers, so it is not until after about three months that we can see better prices. Possible price drop in April: If we look at the price history of its previous generation, it was in April when we began to find more recurring offers, especially until the month of June. Keep an important fact in mind: Around October, we started seeing worse deals on the 128GB Galaxy S25. Because? Apple has a lot to do with it, since the iPhone 17 starts at 256 GB. To compete and sell, stores stopped launching offers on the 128 GB version, and began launching more on the 256 GB version. Hence, except in December, in November 2025 and in January and February 2026 we have seen crazy prices. So? If you see the price for 999 euros (RRP), you are losing money. The pre-launch “street price” right now is around 940 – 950 euros, don’t pay more than that, especially for the 256 GB base model. The best Samsung Galaxy S26 deals now: In the pre-launch period, both the official store and many suppliers have their own offers: Samsung has it for 749 euros paying with Bizum or Samsung Pay and with a direct discount. It allows you to have double the storage (512 GB) without paying more and you can save more money by handing over your old device. MediaMarkt has it for 899.10 euros if you pay through their app. amazon has it for 949 euros using the coupon and it saves you 100 euros if you are a student. The English Court has it for 999 eurosbut it offers a 5% discount when paying from the app, another 5% discount with the El Corte Inglés card and another 10% when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). fnac has it for 999 eurosbut it offers a 10% discount when purchasing Samsung Galaxy Buds4 (the discount is on the headphones). PcComponents has it for 999 eurosbut it offers training on artificial intelligence focused on Samsung Galaxy, allows you to have double the storage (512 GB) without paying more and allows you to finance the purchase at 0% for up to 36 months. Samsung Galaxy S26 (256GB) The price could vary. We earn commission from these links Is the Samsung Galaxy S26 for you now? To better understand whether or not you deserve to buy the mobile right now, these are the reflections I would make: ✅ BUY IT TODAY IF: You need a cell phone because the one you have is broken or the battery no longer lasts you half a day. You want to enjoy the “new” effect on your mobile, also taking advantage of the fact that it is now on sale. You come from a very previous generation, from the Samsung Galaxy S23 back. ⛔ I DO NOT RECOMMEND IT IF: You have a recent mobile phone, a Samsung Galaxy S24 or Galaxy S25. The improvements, especially compared to the previous generation, are not great enough to justify the purchase at the time of its launch. You are going to pay the official price (999 euros). You can hold out for a few months, until at least April, which is when we start to see better offers. Good alternatives to the Samsung Galaxy S26 that I would buy If you still have doubts about whether or not to buy … Read more

Between Tenerife and Gran Canaria hides an underwater volcano called ‘Enmedio’. The CSIC has just detected activity for the first time

by

Under the waters of the Atlantic, about 80 kilometers southwest of Tenerife and Gran Canaria, hides a colossus that we often forget about. Is called ‘Enmedio’, a name that has quite a joke behind it, but which is nothing more than an underwater volcano with a base of 3.5 kilometers and whose summit is 1,625 meters deep. And although it has been there for a long time, now a scientific team has detected for the first time signs of hydrothermal activity in its depths. A decade. It has not happened overnight, since the team of geologists has spent almost ten years collecting multidisciplinary data driven mainly through the VULCANA project. And the results of the measurements made between 2015 and 2024 now have ended up published in the magazine Bulletin of Volcanology. Here, through oceanographic campaigns that combine high-resolution bathymetry, seismic and geochemistry, scientists they have managed to confirm what until now was only a suspicion: the volcano has an active circulatory system. What have they found? What the team has confirmed with all this information is that there is low-temperature hydrothermal activity at this location. In simple terms, we can now see that the volcano is releasing fluids through a series of fractures and a depression that is in your franc. Although this does not mean that it will erupt in the next few hours. In order to make estimates, it was decided to analyze the water in the vicinity of the volcano, and here the instruments recorded thermal anomalies of up to 0.5 ºC above normal. That is, the water around the volcano was hotter and was also loaded with nutrients such as ammonium or iron oxide, which causes biological alterations in the rocks in the area. There is no rash. Logically, when we read ‘volcanic activity’ and ‘Canary Islands’ in the same sentence, it is inevitable to think about volcanic eruptions such as that of Cumbre Vieja in La Palma, and even more so taking into account the recent earthquakes in the area. However, the CSIC has been quite categorical in this regard, pointing out that this detection does not indicate an imminent eruption and has no relationship with the recent seismic swarms recorded in the area around Teide. A paradise. In this way it is an endemic and latent process. In fact, these hydrothermal vents are excellent news for deep ocean biodiversity. To understand it, we can look back to see how the Tagoro volcano ended up fertilizing the post-eruptive marine ecosystem. Now, Enmedio’s fluids act as a chemical engine that influences the composition of the local ocean and feeds communities of microorganisms that thrive in the most extreme conditions of the seafloor. And although the Enmedio volcano is not a new discovery, this first evidence that it “breathes” marks a before and after in volcanic monitoring in Spain. It demonstrates that under water, more than a kilometer and a half deep, the Canary Islands continue to be an incomparable natural laboratory that, thanks to science, we are beginning to understand better than ever.

Google wants you to spend more time in its app store. So he’s going to turn it into TikTok

by

At the end of 2023, Google warned: at some point the discovery of applications through short videos in the Play Store would be enhanced. A pilot test began in the United States under the name “Play Report”, giving maximum prominence to certain selected applications through short videos in vertical format. What began as a pilot test appears to have worked successfully. The company just announced a package of news that will come to Android and, among them, is this type of videos. The fact that. Google is going to introduce Google Play Shorts. Their name does not deceive: they are short format videos in which we will be shown the content and operation of the applications. As soon as we open the application, we will see them playing, so the first question we ask ourselves is whether it will be possible to eliminate its autoplay to save data. Because. Google is not hiding, it wants us to be able to check how an application works without having to leave the Play Store. Until now, if we wanted to consult about any app we used to close the store, look for information in another source, and return to download it. The objective of the Play Shorts is that we have enough hook with the video, and we go on to download the application directly. As. The videos will be integrated into the apps section itself, they will not have an independent section. Or, in other words, a priori they seem inevitable. We will open the Play Store and at the beginning we will have these Play Shorts. They will be integrated into the app files themselves but, to boost downloads, there will be an installation button in the video itself. When. “Soon.” The key here is that the function has come out of pilot testing and will soon arrive on Android. Over the next few weeks, and through a server update, these new ads will progressively appear. TikTokizing Play Store. While the European Union puts infinite scroll in the spotlightGoogle has just added it to its most used application. Once we enter Play Shorts, we can slide down to see more and more applications, a format identical to that of TikTok, YouTube Shorts and Instagram Reels.

Apple is back with the ‘cheap’ MacBook. This time it’s really cheap

by

Five devices in three days. That was Apple’s plan for this week, a plan that culminates with the new MacBook Neo. This is a new attempt by the company to bite into the cheap laptop segment and, although we know that ‘cheap’ does not mean the same for us as it does for Apple, in this case… it is true. Next, we go with all the features of a MacBook Neo that targets a very specific segment and that does not come with an M processor, but with that of the iPhone 16 Pro. Yes, we have not missed the mark with the iPhone model. MacBook Neo technical data sheet MacBook Neo screen 13 inch LED screen Resolution of 2,408 x 1,506 pixels 219 pixels per inch 500 nits brightness processor A18 Pro RAM 8GB storage 256GB ports UBS-C 480 Mb/s USB-C 10GB/s Headphone port WEIGHT 1.23kg Camera FaceTime HD at 1,080p Connectivity Wi-Fi 6e Bluetooth 6 battery 36.5 Wh battery 20W charging Up to 16 hours of battery price From 699 euros Laptop body, iPhone 16 Pro heart The design of the MacBook Neo is very reminiscent of the MacBook Air with the latest redesign. At least, on the outside, with those very rounded corners and a somewhat more robust finish. On the sides there are only two ports (two USB-C that do not go at the same speed, but can be used interchangeably for charging) and the two speakers. The body is made of aluminum, the keyboard has good-sized keys and the trackpad is as large as usual, but the pronounced bezels return on the screen. If the iPhone 17e maintains the traditional notch, the cheap MacBook has not switched to the notch of its older brothers. The screen has a maximum brightness of 500 nits (which is not too much, but enough for indoors) and the resolution yields a density of 219 pixels per inch. On the outside it looks like a MacBook but the trick is that on the inside it’s not a MacBook: it’s an iPhone. In your file in the web From Apple, the company does not dwell much on the processor either. It simply says that it is enough for daily tasks. What tasks? Emails, video calls, surfing the Internet… and puts many practical cases in the classroom. We are looking at a MacBook for students or for mobility with up to 16 hours of autonomy. And, again, it is thanks to the fact that its SoC is that of a mobile phone. This is the Apple A18 Pro, the same one that ‘fit’ the iPhone 16 Pro. It is a more than enough chip for daily tasks, for somewhat more demanding tasks such as occasionally editing a video, for consuming content and even for games. But, even if it has a mobile SoC, the system is MacOS, with everything that this implies in terms of productivity, functionality and the interconnection that we are already accustomed to with the iPhone. The iPad is sure to watch with jealousy that an Apple A18 Pro can handle macOS while he rides up to an M5 with iPadOS. MacBook Neo launch and price The MacBook Neo will hit the market on March 11. You can book now and will arrive at two prices: 256 GB capacity with Magic Keyboard for 699 euros. 512 GB capacity with Magic Keyboard with Touch ID for 799 euros. And, like its brothers, it will not include a power adapter. In development…

Sam Altman has spent his entire life saying one thing and doing exactly the opposite. And this time it didn’t even take 48 hours.

by

A Mecano’s great song —I know, this is very Kiss FM—he said that ‘the face you see is a Signal ad’. And in case any of our painfully young readers don’t know, Signal is a brand of toothpaste. And if there is anyone whose face is exactly like that, it is Sam Altman, CEO of OpenAI, who with a perfect and convincing smile tries to convince the world that his company is just as perfect and convincing. For many people, today is not the case. what has happened. These days we have seen how the US and its Department of Defense (or War, as they like to call it now) have decided that if any AI company wants to work with them, they are going to have to let them use the AI ​​as they see fit. That we have to massively spy on people? He spies on her, totally, we have already done it. What should we tell AI to develop lethal autonomous weapons? Well too. Anthropic stands. But lo and behold, precisely the company that was working with the Pentagon He said that oranges from China. Anthropic, which had been collaborating with the Government for months—Claude was used for the arrest of Nicolás Maduro—, has made it clear that there are red lines that he will not cross. If Anthropic doesn’t want to, let OpenAI do it. At the Pentagon they have threatened to turn Anthropic into a pariah company, but at the moment they have not made any official move. What has happened is that the US Government has decided to change its technological partner. OpenAI has replaced Anthropic and appears to have reached an agreement to work with US defense and security agencies. Sam Altman seizes the opportunity. This has been indicated by Sam Altman, who in an ad on Twitter (I still resist calling her “X”) explained that her company had agreed deploy their models on the US War Department’s classified network. The curious thing is that this agreement establishes the same red lines that Anthropic had: no espionage on American citizens and no autonomous weapons. In the official announcement they even highlight that their agreement “has more safeguards than any previous agreement for classified AI deployments, including Anthropic’s.” There is, for example, one more requirement: that their models not be used for “social credit” systems with which citizens are rated based on the information collected from them. But. Although both Sam Altman and the company’s blog appear to place limits on the War Department’s use of its AI, the terms of that agreement contradict Altman’s claims. The announcement mentions a specific paragraph of the agreement that explicitly states the following: The War Department may use the AI ​​system for all lawful purposes, consistent with applicable law, operational requirements, and well-established security and oversight protocols. “The AI ​​system will not be used to independently direct autonomous weapons in any case where human control is required by law, regulation or Department policy, nor will it be used to make other high-risk decisions that require approval from a similarly competent human decision-maker.” Mass spying on American citizens is legal in certain scenarios as part of the Patriot Act that was passed after the 9/11 attacks, and that would allow AI to process data and communications collected by mass surveillance systems. Jeremy Lewin, a State Department official, has indicated that this agreement “flows from the pillar of ‘all legitimate use’”, and points out that what Altman proposes regarding red lines is not as clear-cut as it seems. Internal protests. Last Friday at 5:01 p.m., Anthropic was due to accept the Pentagon’s terms, but it did not do so. During that morning, several OpenAI and Google employees showed their support for the ethical and moral positioning of the rival company, and almost 800 of them (681 from Google, 96 from OpenAI) signed an open letter entitled “We will not be divided.” Altman says one thing, does another. In an interview with CNBCSam Altman said on CNBC that despite all the differences he has with Anthropic, “I trust them as a company, and I think they really care about safety.” On Thursday, the CEO of OpenAI sent an internal statement expressing his desire for “things to de-escalate between Anthropic and the Department of Defense.” The message came to nothing less than two days later, when he announced the agreement with the same Department.

The world against OpenAI. Many have ended up criticizing OpenAI’s way of acting on social networks. On Reddit they appeared several messages that encouraged users to “Cancel ChatGPT” with thousands of positive votes and also thousands of comments in which the tone was indignant with the way in which OpenAI and Sam Altman have taken advantage of this circumstance. We have seen critical movements in the past —Facebook, Netflix—, but it usually happens that after these first moments, companies end up recovering from the criticism and even come out stronger for a simple reason: Human beings have very bad memories.

A star 1,540 times larger than the Sun is mutating in real time and it is something that baffles astronomers

by

The universe is rarely in a hurry, since stellar processes usually be measured in millions or billions of yearsso witnessing the metamorphosis of a great star in the span of a single human life is practically unheard of. And this is precisely what is happening with WOH G64a true cosmic monster located in the Large Magellanic Cloudabout 163,000 light years from Earth. Big changes. Astronomers have been analyzing this astronomical giant for years, and now the red supergiant is changing radically in front of our telescopes as it heats up rapidly and opens a heated scientific debate. The question that the community is asking itself right now is whether we are facing the transformation towards a very rare yellow hypergiant or if it is simply the fierce interaction of a binary system before collapsing. What we knew. Discovered in the 1970s, WOH G64 has long held the title of one of the largest stars known. The data we know about it is no wonder, since it has a radius 1,540 times greater than that of our Sun, an approximate mass of 28 solar masses and shines 282,000 times brighter than our star. Despite its enormous size, it is an extremely young star, since it is barely 5 million years old. And if we put it into context, in the ruthless world of astrophysics, the largest stars “live fast and die young”, devouring the fuel inside them at great speed. The script twist. Until recently, everything fit the classic profile of an extreme red supergiant, placing its temperature at 3,400 ± 25 degrees Kelvin. But a turning point came in the last decade after the data published in Nature Asia which pointed out that the star suffered a mysterious dimming in 2011, followed by a sudden warming of more than 1,000 ºC and significant chemical alterations in the atmosphere. Now, a new study analyzes the photometry and optical spectroscopy accumulated over more than thirty years of this star. And the conclusion they have reached is that between 2013 and 2014, WOH G64 began to transition from red supergiant to yellow hypergiant. What are they? Yellow hypergiants are an exceptionally rare transition phase of which we barely have data and, above all, it is very ephemeral. In this case, the dramatic thermal evolution could be due to the star having partially ejected its outer envelope or to its stellar companion aggressively stripping away material. The debate is served. As is often the case on the frontier of astrophysics, not everyone agrees that the transition is complete. Rigorous science requires fact-checking constant, and recent research adds nuance to this story. This same year, one study pointed out because the star continues to maintain its classic red supergiant characteristics, questioning whether it has become a rare yellow hypergiant. The most logical explanation they see in this case is that the interaction with its companion star is causing these large temperature changes. This generates a great debate, since it goes completely against the other part of astrophysics that is convinced that we are facing a great twist in the script. A supernova. The big question that everyone is asking is how this titan will end, and some voices suggest that we are seeing the prelude to an imminent supernova. However, in astronomical terms, “imminent” is an elastic concept, since core collapse could occur in a time frame ranging from 100 to a few thousand years. And even if it collapses, even a spectacular explosion is not guaranteed. Although there is also the possibility that it fails in its attempt to explode and, instead, collapses directly in on itself, silently forming a black hole. Likewise, what happens seems to be something that our next generations will see.
