An affair has become a matter of national security. The revelation that Nvidia CEO Jensen Huang has had an extramarital affair with a possible Chinese spy has shaken Washington. Especially because in recent months Huang had become a prominent figure within the circle of tech moguls surrounding U.S. President Donald Trump. During the trip to China in May, only Huang and Elon Musk had the privilege of flying with the Republican on Air Force One. The president announced tonight that the FBI is investigating Huang, but said he is confident that he knew nothing: "I believe him," said Trump.

The hangover from the Republican victory in last Tuesday's US legislative elections has caused sharp falls among some of the main technology companies listed on the US stock exchange. One of the main ones affected by the drops is the tycoon Elon Musk, who is estimated to have lost more than 27 billion euros.

The latest round of results from the major US tech companies has eroded market euphoria for artificial intelligence (AI). Companies on the scale of Amazon and Alphabet (Google's parent company) have made investors' knees shake because of their spending forecasts on computing infrastructure, which much of the market considers excessive. Even Microsoft, which has managed to save face with positive cash generation, has been far from the stock market exaltation that the giants associated with AI had experienced.

Smart City Expo World Congress (SCEWC), the leading international event on cities and smart urban solutions organized by Fira de Barcelona, reaches its 15th edition with the goal of showcasing technologies that are already contributing to responding to the most urgent urban challenges. Under the theme “Urban Solutions, Real Impact”, the event will bring together, from November 3 to 5, representatives from 1,000 cities, more than 27,000 attendees, over 1,100 exhibitors, and 600 speakers, reinforcing its role as a meeting point for public administrations, companies, and experts.

The Spanish government is determined to approve the decree regulating the requirements for energy, environmental, and resilience sustainability and digital sovereignty for data processing centers (DPCs) in Spain before the general elections on November 29th, even though the deadline is very tight. In this way, it has submitted a new text to the Council of State after studying more than 600 allegations during the public hearing period, as well as the mandatory report from the National Commission on Markets and Competition (CNMC) in which it was pointed out that the government's initial energy and renewable requirements were too "strict".

The owners of Elvis Presley's music rights have filed a lawsuit against the artificial intelligence company Anthropic, founded in 2021 by Dario Amodei, Daniela Amodei, Chris Olah, and Jared Kaplan. The plaintiffs accuse the company of having committed copyright infringement by having used more than 274 of the musician's songs without permission to train Anthropic's AI models. According to the complaint, among the songs used are major hits such as Can't help falling in love, A little less conversation, Don't be cruel, All shook up and Return to sender. The complaint maintains that Anthropic has built its business model on the massive violation of intellectual property on an unprecedented scale.

Since the launch of the first ChatGPT models, Catalan companies have looked at artificial intelligence with curiosity. Adoption has been, according to several studies, rapid but lacking order: according to a report prepared by OpenAI itself, creator of the famous chatbot, 96% of small and medium-sized Catalan companies already use AI in some area of their business. However, nearly 40% declare that they still do not have a formal policy for using it.

Barcelona Cybersecurity Congress will address the impact of AI on cybersecurity in its seventh edition. The event, which takes place from November 3rd to 5th, coincides with the celebration of the Smart City Expo World Congress and aims to respond to the impact of AI on the sector as one of the main threats in a context marked by the acceleration of digital transformation, the growing interconnectivity of systems, and their massive implementation.

The "backbone of the web" faltered yesterday. The publication of two serious vulnerabilities in PHP, the programming language on which 70% of the internet's web pages are based, has shaken governments, companies, and users around the world. After administrations in multiple countries decided to halt the service of many of their pages while waiting for the update that was supposed to resolve the two problems, attempts to exploit these weaknesses have multiplied. According to the CEO of the cloud services firm Cloudflare, Matthew Prince, the announcement has triggered "millions" of cyberattack attempts exploiting the weaknesses exposed in PHP. "In the 10 hours before it was publicly announced, we saw thousands of attempts to exploit them. They jumped to tens of thousands in the following 45 minutes, and now they are in the millions," explained Prince in a post on his page on the social network X.

In an autumn marked by the discourse surrounding artificial intelligence, Europe seemed far from any seat of power. Just a few weeks away from the predictable mega-IPO of Anthropic, and still with the echoes of the controversy over the technology's safety that shook the United States in September, the Twenty-Seven have moved a relevant piece for the first time in recent years. At the beginning of October, Mistral, the French benchmark for AI –the only European player mentioned in the conversation of the most advanced models– launched its latest model, Mistral Large 4, also known "very officially" as le Chonk.

Artificial intelligence (AI) will change the way we work and many other things. Among them, taxes. The tax system of countries will have to adapt. Currently, a large part of tax revenue comes from labor income (wages) through a progressive tax (the more you earn, the more you pay), which is the personal income tax (IRPF). But to the extent that AI will reduce jobs – at least during a transition period during which many jobs will disappear, be transformed, or require less personnel – public coffers will notice it.

OpenAI has released more than 720 working papers that collect mathematical advances put together with very little time, a lot of money, and some "mathematical assistants (AI)" that are a marvel. Once everything is duly verified, we will be able to calibrate its importance. For my part, I reserve the most enthusiastic applause for the day that some central questions in the mathematics of the present are solved (such as the Riemann hypothesis or P not equal to NP). It is certain, however, that the ways of doing things in the mathematical profession –do not worry: like the medical one, it will surpass the 3,000-year threshold– will incorporate an intensive use of the new instruments.

At the end of September, a scandal occurred in France that has shaken the publishing and cultural world. The novel that was leading sales in the rentrée littéraire –most fiction narrative is published just upon returning from the summer holidays– seems not to have been written by its author, Thélyson Orélien, alone, but rather that it is due above all to artificial intelligence.

An OpenAI engineer has been arrested and charged in the United States for hiding a recording device in an executive meeting room at the company's San Francisco office to intercept confidential conversations. The case came to light after the company announced on X this Wednesday that it had discovered a "sophisticated" hidden recording device and had alerted the FBI. According to the federal prosecutor's office, the 35-year-old Saudi engineer, Abdulrahman Alfozan, allegedly placed the device behind a television and consulted artificial intelligence tools to prepare for its installation.

It is May 7, 1959, and a tall, burly man with little hair on his head walks decisively into the Senate House, an 18th-century neoclassical building. This is Charles Percy Snow, a chemist, successful novelist, and advisor to the British government, recently named Baron of Leicester by the Queen for his services to the country. He is preparing to give the Rede Lecture, a prestigious conference held every year at the University of Cambridge, in the United Kingdom. He does not know it yet, but he is about to create a considerable stir that will awaken the wrath of many powerful people and generate a public debate that will last for years.

We find ourselves immersed in a moment of confusion in which, as time goes by, the fight to control the AI narrative becomes more complicated and intensified. To the tension between the different sides trying to either sell, understand, or regulate these technological creations, another plot twist has been added: Donald Trump has ordered that from now on, in governmental affairs, AI shall be called superintelligence, which will also lead to the substitution of the acronym AI for SI. This measure (Trump's true colors are showing) is an attempt to counteract the growing animosity of the citizenry towards AI and its representatives, who in recent months have dedicated themselves to spreading the dangers of developing it without regulation far and wide.

In recent weeks, we have seen how autonomous AI agents from large American companies have hacked companies, US government websites or Australian ones, or United Nations databases. These “out of control” AIs have carried out illegal actions with the goal of achieving the objectives they were assigned. The lack of “alignment” between human values and the amoral actions taken by AIs has led some experts to speak, in extreme scenarios, of a 10% chance that an “out of control” AI could end humanity.

Last December, Donald Trump and Elon Musk met at the White House. It was yet another meeting between the American president and the billionaire owner of Tesla and SpaceX, but in this case, there was a bizarre moment. During the time they shared, Trump asked the artificial intelligence chatbot Grok, developed by Musk's team, how Venezuelans would react to an eventual capture of their president, Nicolás Maduro. A few weeks later, on January 3rd, the United States launched an attack in which they kidnapped the Venezuelan leader.

The President of the United States, Donald Trump, has signed an executive order this Tuesday to replace the term artificial intelligence for superintelligence in federal government official communications. At a time when criticism of the artificial intelligence industry is on the rise in the United States, the decision aims to improve the image of AI.

Aging is a natural process and not a disease. Even so, accumulating years is considered the main risk factor for the most prevalent health problems on the planet, such as cancer or Alzheimer's. The passage of time leaves traces inside cells and causes them to deteriorate. And now, Catalan researchers, led by the Bellvitge Biomedical Research Institute (Idibell), have managed for the first time to identify these traces in blood stem cells in microscopic images.
