There is a whale that has been alive for more than two centuries. And it has things to teach us

by

Stopping aging is one of the objectives that a field of science has right now that is very focused, above all, on preventing diseases as serious as cancer that can be associated with being older. Now the secret does not seem to be in a hidden book, but on a bowhead whale what is one of the oldest known mammals with a life expectancy that exceeds 200 years. A headache. This combination of size and longevity has been a problem for biologists for decades. Precisely, more cells (due to their size) and more time (due to their longevity), the greater the probability that one of those cells will accumulate mutations and turn into cancer, as happens in humans. However, this does not seem to affect the bowhead whale: it is not particularly prone to cancer. This apparent contradiction is known like Peto’s paradox. And now, a team of scientists from the University of Rochester believes he has found the key to this resistance. The importance. With the passage of time, humans accumulate different mutations in our cells that a priori They couldn’t be more important. The change of one nucleotide for another in a very complex sequence of a protein may not alter the resulting amino acid, and it is very common, since our ‘genetic photocopiers’ such as DNA polymerases they are not perfect and they make mistakes in their work when it comes to replicating DNA. And it is precisely in these errors that the probability of suffering from a major disease such as cancer increases. Above all, it is worrying when these errors accumulate throughout life. This makes finding ‘the secret of eternal youth’ crucial for humans and the control of devastating diseases. When we think about anti-aging we automatically imagine wrinkle-free skin, but beyond aesthetics, science is interested in how young the cells are. And this is where the question is that now focuses on the genome of these whales that seem to hold the key to understanding how to reverse our molecular aging. The hypotheses. Why a whale has such a high life expectancy despite its size has led to different scenarios being considered. The first of them is that the whale can have extra defenses, as happens in elephants that have evolved to have extra copies of tumor suppressor genes, such as the TP53. Basically, they have more “police” monitoring the genome so that, the moment there is a cancer cell, it is eliminated by apoptosis. But when researchers tested the whale’s cells, they got a major surprise. Unexpectedly, bowhead whale fibroblasts required fewer oncogenic “hits” (what we can say are mutations) to undergo malignant transformation than human fibroblasts. That is, they are more likely to develop cancer compared to humans. So how come they don’t develop cancer in the wild? If your cells are, in theory, more vulnerable, where’s the catch? The repair. And the trick is not in have many police officers monitoring our cells to ‘kill’ those that get out of controlbut it is about having a big toolbox to fix everything that is not normal. It is something that the team led by Professor Vera Gorbunova discovered in the cells of the bowhead whale. In this case, instead of eliminating damaged cells in a process called apoptosis, the whale had perfected the art of repairing them. Their cells showed an “enhanced” ability and fidelity to repair DNA double-strand breaks, which are the most dangerous type of genomic damage. This results in lower mutation rates than present in other mammalian cells. A protein. The person responsible for this super repair is a protein called CIRBP (cold-inducible RNA binding protein). And the name is no coincidence. These types of animals spend their entire lives in the icy waters of the Arctic, and it seems essential to activate this repair system that is present 100 times more frequent in these animals than in humans. And CIRBP seems a real swiss army knife of repair for everything it can do within the whale’s body. Something that can be summarized in the following points: It protects DNA from degradation so that it ‘holds up’ to being repaired. Reduces the formation of ‘micronuclei’, a clear sign of genomic instability and chromosomal damage. It increases the precision of DNA repair so that the genetic material ends up well assembled and without any type of error. In short, we are talking about a conservative strategy of nature: instead of discarding cells that may still be useful, the whale invests in meticulously repairing them. This not only prevents cancer, but also contributes to its exceptional longevity, as it keeps tissues functional for longer. In humans. The question in this case is whether we can take advantage of this great repair capacity within our body. To do this, the research team introduced the whale protein CIRBP into human cells and the result was a success: the protein improved the efficiency of DNA repair in our own cells. But the star experiment was done with fruit flies. In this case, the researchers engineered the flies to overexpress the CIRBP protein (both the human and whale versions) and the results showed a much longer lifespan and greater resistance to the ionizing radiation that destroys our DNA. The next step is now to breed mice with enhanced levels of CIRBP to see if it also makes them live longer, and who knows if it finally somehow becomes a drug that could be very useful especially for those people who are more likely to suffer from cancer.

Portugal and Spain have proposed that traveling between Lisbon and Madrid be as comfortable as in 1881. This is excellent news

by

31 years after the first promise, we will have a high-speed train from Madrid to Lisbon passing through Extremadura. We will have it, of course, if the plans are fulfilled. And four years later we will be able to travel the space that separates both capitals at high speed. 2030 and 2034. At least that’s what they’ve committed to. Portugal, Spain and the European Commission, who have reached an agreement to bring the connection between Lisbon and Madrid back to life in 2030 with a conventional train and in 2034 with a high-speed line that should make the journey in three hours. The calendar. To launch the line between the capitals, the project requires various phases and actions. Poceirão-Bombel section: new line that will begin construction in 2026 and should be completed in 2029. Évora-Caia section: this high-speed section should be ready in 2026. Lisbon-Évora section: the project study should be completed in 2027. Plasencia-Talayuela section: should be operational in 2028. Madrid-Lisbon at high speed: the new lines should allow travel between the Spanish capital and Portugal in three hours from 2034. In addition, the possibility of opening a Caia-Badajoz-Elvas high-speed line has been raised to reduce times and reach three hours if the planned times are not being met. Target: airlines. One of the great objectives that the European Union has with this new high-speed line is to reduce the number of flights between both cities. They point out in elDiario.es There are currently about 40 daily flights between Madrid and Lisbon. For years, European institutions have been working to reduce the volume of air traffic by improving rail connections. Spain either France These are some of the countries that want to implement policies to reduce them. A 600 kilometer railway line to travel in three hours is exactly the type of trip that can do a lot of damage to airlines if it works correctly. A good example is the Galician runner which, despite requiring more travel time, has made passengers turn their backs on the plane. And Galicia? If travelers who aspire to take their trains from Madrid are the big beneficiaries, Galicia seems to be the big loser. In recent yearsPortugal had insisted that its true intention was to create a high-speed line between Lisbon and Vigo with an intermediate stop in Porto. The project now takes a back seat, however, since they will have to focus efforts on high speed between capitals. In Atlantic They highlight that the European Union has already dedicated more than 250 million euros to promoting high speed in Portugal and more than 750 million euros to do the same in the connection between Extremadura and Madrid, so it seems logical that the first corridor to support this. A continental network. The project to link Lisbon and Madrid on a high-speed line is part of the European Atlantic Transport Corridor. The project plans to link Portugal, Spain, France, Germany and Ireland with intermodal connections that include roads, airports, ports… and railway lines. Regarding the latter, the connection with Madrid would allow connecting Barcelona with Lisbon in less than six hours. It would be a key stage for unite Lisbon with the rest of the European Union by train since, at the moment, the Portuguese capital is isolated by rail. In addition, it would allow rapid connection with other hot spots on the Spanish high-speed rail network, such as Valencia and Alicante or connections with Asturias and Cantabria. The exit to Vigo with the high-speed network that was already planned is the other possibility to reach the north of the Peninsula. The eternal promise. The connection between Lisbon and Madrid is a promise that has been going on for more than 20 years. In The World Order They highlight that the railway connection between both cities is worse today than in 1881 when a train line was opened between both cities for the first time. Between Berlin and Warsaw, they point out, there is a similar distance traveled by seven trains a day. Despite the first promises of having a cross-border AVE ready in 2010the line is still not operational. With the latest advances in the high-speed line, already present between Plasencia and Badajoz, the travel time between Lisbon and Madrid has been reduced to just over eight hours, as explained in The World Order but you have to take three different trains. In 2022, the same trip exceeded 11 hours, collected in The Country. At least 144 years ago, travelers only had to take a train and wait for it to drop them off in one of the two cities.

be the tallest church in the world

by

that the Holy Family It is an architectural jewel, there is little doubt. Which is one of the great icons of Barcelona and one of the obligatory stops for tourists who come to the city, either, as attested by the 4.8 million of visitors it received last year. Now Antoni Gaudí’s temple will be able to boast an added merit: being the highest church of the entire planet, a brand that has just been snatched from the Ulm Cathedral, which held that record since 1890. The key: a little big growth of its central tower. What has happened? That the world ranking of mega constructions has undergone an important change. Above all because of its symbolism for Barcelona, ​​Catalonia and Spain as a whole. Yesterday, almost on the eve of All Saints’ Day, those responsible for the works of the Sagrada Familia they hoisted a piece of the ‘Tower of Jesus Christ’ that has raised the height of the temple to almost 163 m. If the fact were not surprising in itself, it comes accompanied by a surprise for lovers of world records: it has turned the Catalan temple into the tallest church in the world, a merit that has been taken away from Ulm Cathedral. Why’s that? What the temple has just incorporated is part of the cross of the ‘Tower of Jesus Christ’, a centerpiece of the Sagrada Familia. More specifically what they installed on thursday The operators with a crane is the lower arm of the cross (7.25 m and 24 tons), which had arrived in July divided into four panels. Those responsible for the project detail that the piece has a double-turn geometry, a square shape at the base, octagonal at the top and a coating of white glazed ceramic and glass, materials chosen for their “luminosity and resistance to atmospheric conditions.” “Once completed, the cross will have a total height of 17 m, equivalent to a five-story building, and a width of 13.5 m,” they clarify. Why is it important? The Sagrada Familia takes almost a century and a half being built, an extensive period full of ups and downs and marked by milestones such as the death of the father of the project, the architect Antoni Gaudi (1926), the Civil War or the Covid-19 pandemic. Throughout this vast chronicle, the works have celebrated important milestones, but Thursday’s is especially symbolic. The reason? How has he been in charge of remember the Archdiocesan Church of Barcelona, ​​the new piece raises the glonal height of the temple to 162.91 meters. It is expected that in the next few monthsas the works are completed, the ‘Tower of Jesus Christ’ will take another growth spurt until reach 172 mbut the current mark has already been enough to turn the Sagrada Familia into a record building. And who had the record? Right now the tallest church in the world (recognized by Guinness World Records) is the Ulm Cathedrala Lutheran church located in Baden-Württemberg (Germany), built in several phases between 1377 and 1890 and which has a spire that reaches a height of 161.5 m. The difference with the Catalan temple is still minimal, but that will likely change in the coming months as the tower is completed. In summer the temple already conquered another milestone, also thanks to the pinnacle: it surpassed the Mapfre Tower and Hotel Arts and became the largest building from Barcelona. Its construction is possible thanks largely to the money that visitors pay to visit the temple. Last year the 4.8 million of visitors, 2.7% more than in 2023 and even above pre-covid data.

Apple is resisting the push for AI PCs because AI PCs have caused complete indifference

by

On paper everything was the sea of ​​pretty. Copilot+ PCs wanted resurrect and reinvent the PC turning it into a device with which you can do much more with much less effort. There was a lot of talk about TOPS power, how AI would do a lot of things for us, and an argument that would boost sales. Do you know what? Its impact has been practically zero. For better or worse, the PC segment has not undergone major changes. Sales have not suddenly started to grow, nor have they plummeted. If the Copilot+ PCs wanted to boost sales, they certainly haven’t seemed to succeed. But at least they don’t seem to have had a negative impact either. Own elaboration. Data: IDC The arrival of AI features on PCs should theoretically have had an impact on PC sales by boosting them, but also theoretically on Mac sales, from which it should have stolen some share if AI had been an important argument. As we know, Apple has barely emphasized the AI ​​functions of its equipment. Although introduced Apple Intelligence in June 2024, it did so in a very limited way and almost a year and a half later its functions remain modest. Own elaboration. Data: Apple quarterly reports. The people keep buying Macbut not because of Apple Intelligence, but because they are just that, Mac. This has been noted throughout this period in which sales have remained relatively stable. The Mac is a lot of Mac The recent presentation of the MacBook Pro M5 could encourage sales towards the end of the year, but where Apple seems to have a winning horse is in the MacBook Air M4which has only been on the market for eight months and offers an enviable price-performance ratio. In the US, for example, you can get it right now for 800 dollars (without taxes). Here, for 949 euros. Few Windows laptops can compete with Apple’s offering, which is surprisingly balanced and has extraordinary room for maneuver thanks to its Apple M4 chip. When we tested the Acer Swift Go 14 AIFor example, we find a device that at 719 euros is undoubtedly cheaper and boasts 16 GB of RAM and 512 GB of SSD, but is inferior in its chip, the Qualcomm Snapdragon X Plus. In Geekbench single-core it is around 2,400 points, and in multi-core it is 10,500. The Apple M4 is around 3,600 and 15,000 points respectively. Acer’s, like other manufacturers selling PC Copilot+, is on paper a comparatively decent proposal, but still fails to impose that TOPS argument and AI functions. They are there and can help, but they are not a decisive argument at the moment, at least if we look at the sales of these devices. PC sales may pick up and boost in the short term, but if they do it will probably not be because of AI features, but for the simple reason that Official Windows 10 support has ended —although that has small print— and many users and companies may have decided to renew their IT infrastructure. However, the promise that AI was going to revolutionize our PCs remains just that: a promise. Apple seems like it can rest easy. And it must be, because this last quarter the Mac division has grown 13% in revenue compared to the same period of the previous year. Not bad.

The V16 beacons have a SIM with connection for twelve years. We know what you’re thinking

by

If you haven’t bought it already, you have two months left to get one V16 beacon to carry in the car. It is a signaling device with a light and is also connected to share your position. How is this done? With an integrated SIM that offers connectivity for at least 12 years and for which you will not have to pay any fee. It is inevitable to think about it: How can I use this for my mobile? “Free” connectivity. It is one of the requirements that the DGT has set for the beacons that we must all carry in the car starting January 1, 2026. Once connected, the beacon transmits our position to the DGT in order to “protect you, spreading the fact that there is an accident vehicle to the rest of the vehicles that approach the accident site.” The beacon must guarantee connectivity for at least 12 years and its cost will be included in the price of the beacon itself. That is, you buy it and that’s it, you have a connection for years without having to pay more. The dismantled beacon. Image: Iván Linares, Xataka Móvil Well I put it on my mobile. For that you will first have to remove it and we already told you that you will not be able to. Our colleague Iván Linares, from Xataka Móvil, has dismantled one of these beacons and has verified that it is not a SIM card like the ones we have in mind, but that it is soldered to the board. The SIM cannot be separated from the beacon. In fact, it doesn’t even have the usual shape, but rather it is an industrial sim-on-chip, integrated into the circuits of the board, so putting it in your mobile or tablet is not possible. Furthermore, accessing this plate has not been easy either and in order to remove the beacon, Iván has had to unsolder two tin points. Limitations. Although we could easily remove it, it is a specific SIM for this device and has technical limitations. The main one is that it does not have access to the internet, but rather connects to a private network that connects only to the DGT 3.0 connected platform. If we managed to install it on a mobile phone, we would not be able to do anything other than connect to that network. There is more. Even if we manage to overcome all the obstacles, there is an insurmountable barrier. The network used by the beacons (NB-IoT) is designed for a specific use: an emergency device that connects sporadically. If it were to suddenly connect constantly, misuse would be detected and it would crash. So no, the twelve years of “free” connectivity does not apply to mobile phones.

This is how they are using oysters to stop global warming

by

A few days ago we said that 55,000 oysters were about to invade the Mar Menor and, as strange as it may seem, it is good news. It is about the first step of a project of the Spanish Institute of Oceanography to recover the flat oyster in the largest lagoon in the country and, at the same time, introduce a natural biofilter that contributes to solving the dead end in which that area is. And this is just one example of something really curious: for years, oyster farming has been claimed as (perhaps) the (only) “agricultural” industry that is good for the global environment. And it’s not a ’boutade’: we have data. A few days ago, Nature magazine published a very interesting analysis of life cycle in Irish oyster farms. From there we can extract numerous data on its ability to reduce “environmental and climate pollution”: for every ton of oysters, 3.05 kilos of nitrogen, 0.35 kilos of phosphorus and about 70 kilos of carbon are fixed. All aquaculturists they know that oysters are “ecosystem engineers.” They filter water, reduce turbidity, eliminate problematic components and facilitate the robustness of habitats and boost biodiversity. That is to say, there is no doubt about the local benefits of this type of exploitation. The news is, in any case, that this contribution also goes beyond the local. And is it? Compared to terrestrial livestock farming, bivalves usually have a low carbon footprint in relation to their protein density. In fact, according to the analysis we were talking about, the footprint per ton is very manageable and a good part of it is offset by the mineralized carbon of the shells. If they manage well, of course. Because, if we look at the raw data, as a global climate solution, oysters are a modest strategy. In the end, carbon balances depend of the specific site, the management of the bivalves, the reuse of shells and, of course, the energy used throughout the production chain. Therefore, when we talk about “potential to fight climate change” we must keep two things in mind. The first is its ability to show that we can build another food industry. The second is to show that the impact of the things we do goes beyond what we are able to see directly. In the case of oysters, we have to take into account that their impact on water quality and biodiversity is not only powerful and cost-effective; but rather contributes to stopping climate change indirectly. Good news beyond the specific data. That’s the summary: if oysters can change the playing field; If they can push us, even an inch in the right direction… welcome.

China no longer plays in its favor

by

Apple has closed its fiscal fourth quarter of 2025 with $102.5 billion in revenue, surpassing the psychological barrier of $100 billion in a quarter for the first time. Earnings per share have reached $1.85, 13% more than a year ago. Wall Street expected less, so the stock is up 4% outside market hours It is the best quarter in Apple’s history. It is also the one that best exposes its dependence on China. Why is it important. Apple is already worth more than $4 trillion, the third company to reach that valuation after NVIDIA and Microsoft. Its results affect hundreds of suppliers in its production chain. But the growth of the iPhone, which still accounts for half of its revenue, has slowed. China is both a threat and an opportunity: If you regain traction there, the rally continue. If not, services will have to compensate more and more. And they are not infinite. Yes, but. ‘Greater China’ (a region that includes mainland China, Macau, Taiwan and Hong Kong) is the only region that has fallen compared to the previous year. Revenues in that market have been $14.5 billion, 4% less year-on-year and well below the $16.4 billion expected by analysts. Tim Cook has tried to soften the blow by promising that they will grow again in the first fiscal quarter thanks to the iPhone 17but the numbers sing: Apple is losing ground where it hurts most. Besides, Chinese brands are winning the battle of prestige on their own territory. Manufacturers like Huawei, Xiaomi or Vivo are no longer cheap alternatives and have started to position themselves as premium options, with special emphasis on the former. Apple is no longer the only status symbol in a market that manufactures many of its products. The money trail. The Services division has reached $28.75 billion this quarter, 15% more than last year. It is a historical maximum and the figure that really sustains Apple’s growth. In the full fiscal year, Services have exceeded $109 billion, another record. iPhone: 49 billion (+6%). Services: 28,750 million (+15%). Mac: 8,726 million (+13%). iPad: 6,952 million (practically flat). Home, wearables and accessories: 9,013 million (-0.3%). In this last division are Apple Watch, AirPods, HomePod, Apple TV… Services already represent 28% of total revenues but their very high margin compared to hardware means that they generate close to 50% of operating profit. Services, after all, do not require complex supply chains or rely on product cycles. In detail. The tariffs have cost $1.1 billion in the quarter and are expected to reach $1.4 billion in the next. Kevan Parekh, the chief financial officer who has replaced Luca Maestri, has projected revenue growth of 10% to 12% for the December quarter — the first of Apple’s fiscal year — with iPhone sales growing by double digits. Analysts expected only 6%. Cook has highlighted the “very strong demand” for the iPhone 17, launched in September alongside the iPhone Air. They have also mentioned supply constraints, suggesting that they could have sold more if they had been able to make more. The backdrop. Apple depends on China in two directions: As a consumer market. And as a production center. This double dependence is a geopolitical vulnerability that has become more evident with the trade war. The company has tried to diversify its manufacturing towards India and Vietnambut China remains irreplaceable in the short term. Meanwhile, in China, Apple is no longer perceived as the only aspirational brand. Local manufacturers have improved a lot in design, cameras and software, which leads to an improvement in perceived value. And they’ve done it while Apple navigated years of incremental iPhone updates.

We already know how to retrieve the exact prompts that people use in AI models. It’s terrifying news

by

A group of researchers has published a study that once again raises alarm bells regarding privacy when using AI. What they have managed to demonstrate is that it is possible to know the exact prompt that a user used when asking a chatbot something, and that puts AI companies in a delicate position. They can, more than ever, know everything about us. A terrifying study. If you are told that ‘Linguistic models are injective and, therefore, invertible’ you will probably be shocked. That’s the title from the study carried out by European researchers in which they explain that large language models (LLM) have a major privacy problem. And it has it because the transformer architecture is designed that way: each different prompt corresponds to a different “embedding” in the latent space of the model. A sneaky algorithm. During the development of their theory, the researchers created an algorithm called SIPIT (Sequential Inverse Prompt via ITerative updates). Such an algorithm reconstructs the exact input text from the hidden activations/states with a guarantee that it will do so in linear time. Or what is the same: you can make the model “snap” easily and quickly. What does this mean. What all this means is that the answer you got when using that AI model allows you to find out exactly what you asked it. In reality, it is not the answer that gives away, but the hidden states or embeddings that the AI ​​models use to end up giving the final answer. That’s a problem, because AI companies keep these states hidden, which would theoretically allow them to know the input prompt with absolute accuracy. But many companies already saved the prompts. That’s true, but that “injectivity” creates an additional privacy risk. Many embeddings or internal states are stored for caching, for monitoring or diagnosis, and for customization. If a company only deletes the plain text conversation but does not delete the embeddings file, the prompt is still recoverable from that file. The study shows that any system that stores hidden states is effectively handling the input text itself. Legal impact. There is also a dangerous legal component here. Until now, regulators and companies argued that internal states were not considered “recoverable personal data,” but that invertibility changes the rules of the game. If an AI company tells you that “don’t worry, I don’t save the prompts” but it does save the hidden states, it’s as if that theoretical privacy guarantee is of no use. Possible data leaks. A priori it does not seem easy for a potential attacker to do something like this because they would first have to have access to those embeddings. A security breach that results in the leak of a database of those internal/hidden states (embeddings) would no longer be considered an exposure of “abstract” or “encrypted” data, but rather a plain text source from which, for example, financial data or passwords that a company or user has used when asking the AI ​​model could be obtained. Right to be forgotten. This injectivity of LLM also complicates the requirements of regulatory compliance for the protection of personal data, such as the GDPR or the “right to be forgotten.” If a user requests complete deletion of their data from a company like OpenAI, they must ensure that they delete not only visible chat logs, but also all internal representations (embeddings). If any hidden state persists in any register or cache, the original prompt would still be potentially recoverable.

what is this subscription, features and differences with ChatGPT Plus

by

Let’s tell you what are the features of ChatGPT Gothe new subscription of ChatGPT available in Spain. It is a cheaper alternative that gives you access to some advanced functions, but with which you will not be able to use some other extra functions such as creating videos. It is a new subscription that is now beginning to arrive in our country. Still, it is a subscription to consider if you do not want to pay as much for greater access to GPT-5 or advanced imaging, since It costs 10 euros a month. We are going to tell you its characteristics and the main differences with other subscriptions. What is ChatGPT Go ChatGPT Go is the cheapest subscription plan to access advanced features of the artificial intelligence from OpenAI. This is an intermediate plan between the little that the free version offers with its numerous limits, and what the Plus plan offers, which is the “normal” AI plan. Being in this middle place, ChatGPT Go offers expanded access to GPT-5 and any new versions of the artificial intelligence model that come out in the future. It also widens file upload margins and speeds up image creation. But it is missing some things that the Plus version does have, as we will tell you later. So, it becomes an option for those who prefer to pay less and have access to fewer functions that ChatGPT offers. It has a price of 9.99 euros per monthless than half of the 23 euros per month that the Plus version costs, being a more popular price for common users. Features of ChatGPT Go vs. Plus Feature Free ChatGPt chatgpt go ChatGPt plus chatgpt pro Price €0/month €9.99/month €23/month €229/month access to gpt-5 Access to GPT-5 Expanded access for GPT-5 GPT-5 with advanced reasoning GPT-5 with professional reasoning Messages and uploads Limited file uploads Expanded messages and uploads Expanded messages and uploads Unlimited messages and uploads Images Limited and slow imaging Expanded and faster imaging Expanded and faster imaging Unlimited and faster image generation Memory Limited memory and context Expanded memory and context Expanded memory and context Maximum memory and context Deep investigation Limited depth research Limited depth research Expanded in-depth investigation, and agent mode Maximum in-depth investigation and agent mode Projects, tasks, gpts No access Custom Projects, Tasks, and GPT Custom Projects, Tasks, and GPT Expanded Custom Projects, Tasks, and GPT sora No access No access Video generation with Sora Video generation with extended Sora codex agent No access No access With Codex agent With expanded Codex agent Video preview No access No access No access New Feature Research Preview As you can see, the ChatGPT Go version has expanded access to GPT-5, but without advanced reasoning of the plus version. Its in-depth research is limited as in the free version, although hopefully not as much, and it gives you access to the GPTs personalized, and the creation of projects and tasks. ChatGPT Go it doesn’t give you access to Sora and its video creation, nor to the Codex programming agent. It shares expanded memory and context, better image generation, and more file uploads with the Plus version, although OpenAI does not specify the differences that possibly there is. The Plus version is still the standard plan that gives you access to the main features of ChatGPT, from video creation to greater capabilities and advanced reasoning in GPT-5. There is a higher subscription, ChatGPT Pro, but its price is still so high that it is not worth it unless you use AI professionally and always need the highest limits. But hey, at least the Go version gives you a more reasonably priced gateway to features that go beyond the limitations of the free version. This is good news for those who want to use ChatGPT on a daily basis and take advantage of various functions, but without needing it so much as to pay 23 euros per month.

Character.AI has just shown ChatGPT the way to tackle the problem of AI and minors

by

The suicide of a teenager and other cases of delusions have put AI chatbots in the spotlight for their effects on mental healthespecially that of the youngest. ChatGPT has already implemented parental controls in response to this growing concern and a few days ago they admitted to being aware that ChatGPT was causing serious mental health problems for some users. . Now, Character.ai, one of the chatbots that is also at the center of the controversyhas made a drastic decision. +18. United States already is legislating to regulate the use of so-called ‘AI companions’ in minors and Character.ai has gone ahead by taking a more drastic measure than parental control. As they say in TechCrunchStarting on November 25, the app will begin limiting the usage time to two hours for those under 18. Little by little, that time will be reduced until it is zero. Age verification. To ensure that those under 18 can no longer use the app, Character.ai is going to deploy an age verification system that analyzes user behavior. If it fails, the app will use additional identity verification and facial recognition to block users who are not of legal age. ChatGPT, warm up as you go out. OpenAI has recently taken steps to prevent cases like that of Adam Rainemainly the integration of parental control in ChatGPT. The measure contrasts with Altman’s statements days later, when he said that ChatGPT would allow us to have conversations with erotic contentbut only for adults.
