It is extraordinary enough to see the world's top central banker make an unscheduled video statement on social media. My first thought upon seeing the post from the Federal Reserve chair Jerome Powell was: Is this an AI deepfake? That sense did not go away as I listened to what were indeed the real words of the world's most important financial official. The background here is a long-running spat between President Trump and the man responsible for setting interest rates in the US and indirectly much of the rest of the world. In theory, this has officially been about the cost of a renovation project at the Federal Reserve, the US equivalent of the Bank of England.

A deluge of sexual images created by Musk's Grok AI tool has prompted a public and political outcry. A deluge of sexual images created by Musk's Grok AI tool has prompted a public and political outcry. Mon 12 Jan 2026 07.23 ESTFirst published on Mon 12 Jan 2026 06.02 EST The UK media watchdog has opened a formal investigation into Elon Musk's X over the use of the Grok AI tool to manipulate images of women and children by removing their clothes. Ofcom has acted following a public and political outcry over a deluge of sexual images appearing on the platform, created by Musk's Grok, which is integrated with X. The regulator is investigating X under the Online Safety Act (OSA), which carries a range of possible punishments for breaches, including a UK ban of apps and websites for the most serious abuses.

Ofcom has launched an investigation into Elon Musk's X over concerns its AI tool Grok is being used to create sexualised images. In a statement, the UK watchdog said there had been deeply concerning reports of the chatbot being used to create and share undressed images of people, as well as sexualised images of children. If found to have broken the law, Ofcom can potentially issue X with a fine of up to 10% of its worldwide revenue or £18 million, whichever is greater. The BBC has approached X for comment. Elon Musk previously said the UK government wanted any excuse for censorship in response to a post questioning why other AI platforms were not being looked at.

Malaysia and Indonesia are the first to block Grok over explicit deepfakes that the chatbot has been generating. The UK's media regulator has opened a formal investigation into X under the Online Safety Act. There have been deeply concerning reports of the Grok AI chatbot account on X being used to create and share undressed images of people -- which may amount to intimate image abuse or pornography -- and sexualized images of children that may amount to child sexual abuse material (CSAM), Ofcom said. The investigation will focus on whether X has has complied with its duties to protect people in the UK from content that is illegal in the UK. That includes whether X is taking appropriate measures to prevent UK users from seeing priority illegal content, such as CSAM and non-consensual intimate images; if the platform is removing illegal content quickly after becoming aware of it; and whether X carried out an updated risk assessment before making any significant changes to the platform.

The UK's media regulator has opened a formal investigation into X. Malaysia and Indonesia are the first countries to block Grok, claiming that X's chatbot does not have sufficient safeguards in place to prevent explicit AI-generated deepfakes of women and children from being created and disseminated on X. Indonesia temporarily blocked access to Grok on Saturday, as did Malaysia on Sunday, the reports. Meanwhile, UK media regulator Ofcom has opened a formal investigation into X under the Online Safety Act. The government sees non-consensual sexual deepfakes as a serious violation of human rights, dignity and the safety of citizens in the digital space, Indonesia's Communication and Digital Affairs Minister Meutya Hafid said in a statement. Officials in the country said initial findings showed that Grok lacks effective controls to prevent users from creating and sharing sexually explicit deepfakes based on photos of Indonesian residents.

The astronaut training tourists to fly in the world's first commercial space station Former NASA astronaut Drew Feustel now leads the astronaut training program for the private space company Vast, which aims to put its Haven-1 station into orbit in May. For decades, space stations have been largely staffed by professional astronauts and operated by a handful of nations. But that's about to change in the coming years, as companies including Axiom Space and Sierra Space launch commercial space stations that will host tourists and provide research facilities for nations and other firms. The first of those stations could be Haven-1, which the California-based company Vast aims to launch in May 2026. If all goes to plan, its earliest paying visitors will arrive about a month later. Drew Feustel, a former NASA astronaut, will help train them and get them up to speed ahead of their historic trip.

I asked my MIT class to consider why some of the advances that MIT Technology Review's journalists thought would change our world never really did--and what we can learn from the flops. Every year, publishes a list of 10 Breakthrough Technologies. In fact, the 2026 version is out today. This marks the 25th year the newsroom has compiled this annual list, which means its journalists and editors have now identified 250 technologies as breakthroughs. A few years ago, editor at large David Rotman revisited the publication's original list, finding that while all the technologies were still relevant, each had evolved and progressed in often unpredictable ways. I lead students through a similar exercise in a graduate class I teach with James Scott for MIT's School of Architecture and Planning.

Our reporters and editors constantly debate which emerging technologies will define the future. Once a year, we take stock and share some educated guesses with our readers. Here are the advances that we think will drive progress or incite the most change--for better or worse--in the years ahead. Rubrik is the exclusive sponsor of the 10 Breakthrough Technologies 2026 and had no editorial influence on this list. Rubrik is a security and AI operations company that aims to secure and accelerate the world's AI transformation.

When Hollow Knight: Silksong came out last summer I was in so much pain that I didn't know if I'd be able to play it. Could a video game teach me anything new about suffering? L ast year I became uncomfortably well acquainted with suffering. In March I started experiencing excruciating pain in my right arm and shoulder - burning, zapping, energy-sapping pain that left me unable to think straight, emanating from a nexus of torment behind my shoulder blade and sometimes stretching all the way up to the base of my skull and all the way down into my fingers. Typing was agony, but was painful; even at rest it was horrible.

By studying large language models as if they were living things instead of computer programs, scientists are discovering some of their secrets for the first time. How large is a large language model? Think about it this way. In the center of San Francisco there's a hill called Twin Peaks from which you can view nearly the entire city. Picture all of it--every block and intersection, every neighborhood and park, as far as you can see--covered in sheets of paper. Now picture that paper filled with numbers. LLMs contain a LOT of parameters. That's one way to visualize a large language model, or at least a medium-size one: Printed out in 14-point type, a 200-billion-parameter model, such as GPT4o (released by OpenAI in 2024), could fill 46 square miles of paper--roughly enough to cover San Francisco.
