Fusion power startup Cambridge Heavy Industries is building a small, laser-powered fusion device to fuel the coming wave of fusion power plants.

An employee at OpenAI was arrested and charged with using a hidden recording device in one of the company’s San Francisco offices, according to statements from the artificial intelligence company and the US Justice Department.

The author went on a full-moon walk at Iguazú Falls at night. Courtesy of the author My husband and I booked a nighttime tour of Iguazú Falls during the full moon. We walked through the forest in darkness, listening to wildlife and rushing water. The moonlit waterfalls were unlike anything I'd seen during my many daytime visits. I'm originally from Argentina and grew up in Brazil, so I've been to the Iguazú Falls — which sit between the two countries — plenty of times. This year, I decided to take my husband and kids to see the world's largest waterfall system, since they had never been before. And while their minds were blown during our daytime visit, it was the night walk I took with my husband through the falls that, honestly, took my breath away. The full moon tour is small and private The night tour is only available during a full moon, and you can choose different time slots. We were there with friends for a wedding and chose the 9:25 p.m. slot to guarantee it'd be really dark out. While kids are allowed on the full-moon tour, we decided to leave ours at the hotel with my mom so we could fully enjoy the experience. The author walked in the dark through the Iguazú Falls. Courtesy of the author Our tour had 120 people, which is relatively small compared to the thousands you can encounter walking along the metal walkway leading to the falls during the day. The experience felt intimate because we were such a small group, which gave us space and time at every stop. The walk starts right before the falls, with a small performance by the Guaraní, the indigenous people of that part of Argentina. There, our guide also explained what certain words meant, for example, Iguazú means "big water" in Guaraní. The moon guided our way After the performance, we started walking through a thick forest in the dark. The guides told us to use all our senses to experience the national park in a way very few ever do, and they were right. We started noticing different chirps and squawks from insects, birds, and monkeys. There were also different smells coming from the forest. But one sound was undeniable. Even before we reached the falls, the sound they made was so loud that it was hard to ignore, and it grew even louder as we approached. The author heard the waterfalls before she saw them. Courtesy of the author Throughout the tour, we weren't allowed to use flashlights or flash photography. The whole point was to let your eyes adjust to walking in the dark and to let the moon guide you. It was pretty mind-blowing to see how your vision changed the further we went into the park; it didn't feel like nighttime. The waterfalls are breathtaking As soon as we approached the first fall, you could hear everyone gasp and stop to take photos. The enormity of the falls is pretty breathtaking, but also feeling their power at night is indescribable. Even as a writer, I lack the words to explain how powerful it felt. There are two circuits to the falls: top and bottom. Because the water levels are currently so high because of El Niño (so much so that Argentina had to close some parts of the park), we were only able to experience the top circuit during our visit. We missed out on the Devil's Throat, which gets you incredibly close to the falls. Our route let us see the waterfalls from above and the high jumps the water makes before it reaches the ground again. Argentina had to recently close parts of the tour the author took because the water is so high. Courtesy of the author At times, I just stood there, mesmerized by the sounds of the water splashing with all its intensity, surrounded by mist, under a sky covered in stars. My husband, who was experiencing it all for the first time, kept saying "wow" over and over. At one point, it was just him and me on a long metal structure overlooking the river right before the falls. It felt like we had the whole park to ourselves, and it was the most romantic thing we've done after many years of parenting little kids. We made it back to the entrance of the park around midnight. We brought our kids during the day The next day, we took a trip to the Brazilian side of the falls, which offers a panoramic view of this natural beauty. We rode a boat with our kids and friends close to the falls, where we got soaked and saw plenty of rainbows. On the way back to our car, we saw coatís and monkeys. After that, we took our kids to experience the same walk we had taken under the bright full moon, but during the day. Seeing the difference between what a daytime and a nighttime tour offers, I was left wishing we had taken the kids on the full-moon trip. Before we even left Iguazú, my oldest was already asking us when we were coming back. Read the original article on Business Insider

A federal magistrate judge took Elon Musk to task over a statement he made about a fired federal employee. Kevin Dietsch/Getty Images A federal judge tore into a February 2025 post Elon Musk made on Twitter about a fired official. The judge wrote that Musk "clearly intended" to make the official feel "afraid." Judge William Fitzpatrick took issue with what federal officials said about the firing of FEMA CFO Mary Comans. A federal judge tore into Elon Musk for reposting a photo of a former Federal Emergency Management Agency official and accusing her of "criminal" conduct. "The fact that Mr. Musk posted a picture of Ms. Comans to his millions of followers while falsely characterizing her government service as a 'criminal action' was clearly intended to make her afraid," Federal Magistrate Judge William Fitzpatrick wrote in a ruling published on Tuesday. In a blistering eight-page ruling, Fitzpatrick addressed what he described as the reputational damage to Mary Comans, a longtime federal government employee who was fired from her post as chief financial officer of the Federal Emergency Management Agency in February 2025. Musk's February 11, 2025, post, which was made when he was de facto leader of the White House DOGE Office, "served no legitimate governmental interest and was little more than state sanctioned intimidation," Fitzpatrick wrote. Fitzpatrick wrote that federal officials knew at the time that it was false to accuse Comans of trying to circumvent President Donald Trump's executive order that paused federal funding to non-governmental organizations assisting migrants. Nonetheless, Musk and then-DHS Secretary Kristi Noem, among others, made statements that Fitzpatrick wrote impugned "the personal and professional integrity of Ms. Comans," Fitzpatrick wrote. "For reasons unfathomable to this Court, officials chose to turn the power of the federal government against a singular employee with an impeccable record of public service," Fitzpatrick wrote. "In short, Ms. Comans was professionally targeted and personally attacked by government officials for no legitimate reason." Musk's post on X was one of seven statements Fitzpatrick addressed in the ruling. Musk quote-tweeted a post that posted a picture of Comans and Trump with the text, "FEMA CFO Mary Comans was just fired for funneling $58M to illegal migrant hotels in Manhattan. FA, FO." In his post, Musk added, "A criminal action." Fitzpatrick wrote that it was clear to other federal officials that Comans had no authority to stop specific grants, and that others had decided to continue funding state and local programs like the ones Musk took issue with. Musk and Noem have since left the Trump administration. The White House did not immediately respond to a request for comment from Business Insider. Fitzpatrick wrote that the federal government did not dispute a list of facts about the case, including that federal officials at DHS and FEMA knew that statements about Comans' firing were false when they were made. Tuesday's ruling is just one part of the broader legal fight over Comans' firing. In July, US District Judge Michael Nachmanoff ruled that Comans was unlawfully fired. The Trump administration is appealing that ruling. Read the original article on Business Insider

Alcibiades being taught by Socrates, Francois Andre Vincent (1777). Wikimedia Commons, CC BY Most students now use AI in their tertiary studies. AI can also, under certain conditions, answer at least 65% of questions correctly in STEM subjects. In the humanities, where the whole aim is critical and creative reflection, educators face a thorny question. How do you develop and measure thinking of the kind that a machine could not genuinely imitate? AI has proved it can answer questions well. But can it ask questions? And can it ask the right questions? This is the philosophical method at the heart of the work of the Ancient Greek philosopher, Plato. His Socratic method of teaching is, perhaps, the mode of thinking we need to emulate in our teaching and learning today. The great questions Plato wrote dialogues: texts that read (in nearly every case) like a conversation between Socrates (Plato’s teacher) and a partner drawn into conversation by Socrates after claiming to know something about living a good and virtuous life. Goodreads There is a dialogue for all the great philosophical questions: what justice is; what courage or love really requires; what makes a good friend; and even how we acquire knowledge. In each case the conversation is set by Socrates, who questions someone who seems to possess knowledge about a certain thing, or who has come to Socrates for advice. It is not just the content of these dialogues that has prompted centuries of discussion, but their form. Plato’s dialogues are extraordinary literary achievements, drawing on a range of genres and placing characters, historical and fictional, inside deliberately constructed settings. These are challenging and strange texts in many cases. They ask of their readers not just to read them as dialogues, but to call into question what we think we know. The Euthyphro Take the Euthyphro, the dialogue students most often meet first, which opens the sequence of dialogues dramatising Socrates’ trial and death. Socrates is on the way to his own trial, over (politically motivated) charges of failing to honour the gods of this city, introducing new divinities and corrupting the youth. He meets a man called Euthyphro, who is on his way to court to accuse his own father of murder. Euthyphro insists this is the pious thing to do. To Socrates, this is evidence that Euthyphro must know something about what piety is. Dialogue ensues. Socrates leads Euthyphro through a frustratingly methodical discussion using elenchus, also called the Socratic method. The method proceeds roughly like this. One person, Socrates, mostly asks the questions. The partner must respond to every question. A definition or principle relevant to the discussion is sought from the partner. Socrates seeks clarification, gaining assent to various propositions. Those propositions are used to show that the definition under examination is unsatisfactory. This continues until the partner flees, erupts in frustration, or admits to being in a state of perplexity, called aporia. It is this final step, the experience of aporia, that sits at the centre of the early dialogues. Aporia teaches us that we don’t know what we thought we knew, and we are all the better for finding out. After all, it is better to have knowledge of our ignorance than to be ignorant of our ignorance. This is the product and achievement of the method, though Socrates’ partners rarely saw it that way. His incessant questioning of often prominent Athenians earned him a bad reputation. Ultimately, he was sentenced to death. The Death of Socrates, Jacques Louis David, 1787. Wikimedia Commons, CC BY-NC-SA An invitation But there is more to the Euthyphro, and to all of Plato’s dialogues, than what the characters say. As modern readers of them, we are set a challenge. We can read along while Euthyphro falters at every turn, unable to show that he knows anything about piety, until he storms off and the dialogue ends. We can then close the book and go on with our lives. But to do this would be to be no better than Euthyphro who, after having his ideas of piety brought under examination, realises he must not know as much as he thought. Plato’s invitation, through the dialogical form, is to bring us into the conversation with Socrates. What do we think piety might be? Each dialogue puts us in touch with a question about an idea in this way. The dialogues ask what love, friendship, knowledge, and so on, could be. And to be properly engaged with these texts, we have to follow Socrates’ successive attempts to define the thing under examination. The aporia at the close of the dialogue is often shared, too, by readers joining this conversation more than 2,000 years later. This is one of the great lessons of studying Plato. Plato’s texts are not decrees or collections of aphorisms as they are sometimes treated to be. They are the beginning of a philosophical conversation with ourselves. They portray far more than the ideas of one Ancient Greek philosopher. They set out a way of doing philosophy, of thinking critically and creatively about who we are, our relationship to the world and to each other, and what we really know. This is not just the Socratic method, but Plato’s central teaching. Philosophical dialogue as a way of knowing. Uses today What Plato’s dialogues show is that learning takes place through the to-and-fro of reflective thought and that much of learning is really unlearning. Socrates picks his partners because they claim to know something and the discussion shows that claim to be hollow. But, crucially, the result of the discussion is to arrive at a question that is now far more refined. The question is where learning begins. To want to know something, you must already have some grip on what it is that you don’t know. You have to recognise the shape of the gap in your knowledge. If I want to understand how plants photosynthesise, for example, I must first have noticed there is a process behind the plant’s survival, something about its need for sunlight, that I don’t yet understand. The desire to know begins in acknowledging what I don’t know and this is why the aporia Plato directs at his reader is not a dead end. It is where philosophy, and all of our seeking and learning, begins. A student who asks AI to explain the causes of the French Revolution (simply because this was a question assigned to them) has asked a question, but not one that costs them anything. Nothing in their own understanding was at risk in the asking. The question that matters, philosophically, is the one that exposes a gap in the knowledge of the one who is asking – and this is precisely what AI cannot do on the asker’s behalf. AI can fill gaps. It cannot locate them for you in any way that counts as learning. This is exactly what is foreclosed when a student turns to AI before they have sat with their own aporia or confusion. AI answers before the question has been sharpened, and often before the student has worked out what they were really asking in the first place. The danger is not that students get answers. Students have always sought answers, from textbooks, from teachers, from each other. The danger is that the experience of aporia is skipped entirely and the authentic and generative question that might have led somewhere is never found. The difference between asking a question, and asking the right question, is in the proper determination of the limits of our knowledge. So, although the adage goes, “there is no such thing as a silly question,” some questions are seemingly more meaning bearing than others. They are the questions that genuinely express our wanting to know the answer. I am suggesting this is what reflective, question-posing teaching and learning could recover. To develop and assess a student’s learning today, we could find ways for students to identify and then evaluate the gaps in their own knowledge. This means, as some universities have started to do, encouraging and assessing dialogue in the classroom and utilising reflective, as opposed to purely descriptive, assessments. From here, the teacher’s task is to encourage the student to pose new meaningful questions, which are interconnected with the student’s own learning journey. Now, of course, this cannot replace every other mode of teaching and learning. The descriptive and practical training that a chemist or a mechanic receives cannot simply wait for students to ask the right questions, and explicit teaching and demonstration remain indispensable for the development of technical skill. But it would be a mistake to think only the humanities benefit from the Socratic method. Every profession contains moments where the expert must make a moral judgement and the answer cannot simply be looked up. But the deeper contribution the Socratic model makes beyond philosophy is not confined to ethics. It is the cultivation of judgement itself, the capacity to find the right question, which sits at the heart of expertise wherever it is found. Socrates made this point when he claimed his only advantage over his fellow Athenians was knowing that he did not know. We now have a tool that seems to know almost everything. The task for tertiary education is not to compete with AI at answering. It is to protect the conditions under which students still recognise what they do not know. That recognition cannot be outsourced. It is where genuine learning begins.

Nvidia chief executive Jensen Huang, centre, speaking at the White House. OpenAI president Greg Brockman is on the right. AP Imagine a company that sells you equipment, invests money in your business, and then rents back what you build with it. It’s your supplier, your investor and your customer all at once. That’s known as circular financing. Many artificial intelligence (AI) companies, including Microsoft, Amazon, Google and Nvidia, have adopted a version of this opaque method of financing. A chip supplier invests in a customer such as a data centre builder, the customer spends the money on the supplier’s chips, and both companies report growth. One central bank analysis found that 55.2% of investments into AI firms came from other AI firms. What’s not clear to investors or the market is how much of this AI boom is being driven by real, end-user demand — and how much might be a bubble. It all comes back to Nvidia Take Nvidia. The world’s leading chipmaker is investing in ChatGPT owner OpenAI to support data centres filled with Nvidia chips. Nvidia will invest US$30 billion in a private funding round in OpenAI and provide a guarantee of up to US$105 billion for an OpenAI data centre in Ohio, as well as investing in the company building it. That helps OpenAI to remain Nvidia’s best customer, but it also raises the question: is the chipmaker propping up the market? Nvidia has invested in other AI firms as well, including up to US$10 billion in Anthropic, the developer of Claude. It bought US$2 billion of shares in cloud provider CoreWeave to help it speed up the build-out of AI factories that use Nvidia technology. In total, Nvidia made more than 50 different investment deals in AI companies in 2024 alone. Some of those deals are staged over years or still open-ended. But these circular deals help the AI build-out move faster than it could without Nvidia’s financing. The Australian story – Firmus Data centre builder Firmus – which last week dramatically abandoned plans to list on the Australian Securities Exchange – provides the local example. Nvidia wears all three hats for Firmus: Firmus chief executive Oliver Curtis. His $$44 billion IPO failed to win investor support. Supplied Investor: Nvidia first invested in Firmus Technologies through the company’s A$330 million capital raising in September 2025 to finance data centres in Tasmania. It then participated as an existing investor in two further funding rounds, one in April 2026 and Firmus’s US$2 billion funding round in August 2026. Nvidia did not disclose how much it invested. Supplier: Firmus plans to build data centres using Nvidia’s DSX AI factory platform, which combines chips, networking and software to provide computing capacity Customer: Firmus signed Nvidia as a customer for its data centre in Batam, Indonesia, worth up to US$30 billion over six years. Meanwhile, Open AI (with its existing relationship with Nvidia) has been named as an anchor customer at Firmus’s Malaysian data centres. These circular deals also concentrate risk The same loop concentrates risk. With Nvidia acting as investor, supplier and financier across the AI sector, trouble at one firm can spread quickly to the others. It also complicates valuations. For instance, OpenAI’s method of reporting revenues has been queried. Its shares were hit last week when the Financial Times reported its annualised revenues were US$20 billion less than the company had suggested. The Reserve Bank of Australia warned in its recent Financial Stability Review that there are “pockets” of higher-risk companies, including those using opaque or circular funding arrangements, where chipmakers provide financing to the companies that purchase their products. Warning about the possibility of the AI bubble bursting, the RBA said: One possible trigger could be a shift in sentiment towards the AI investment boom, which is increasingly fuelled by expectations of sustained rapid earnings growth and a debt-financing cycle that is becoming more opaque and circular. The concern is that nearly all the gains in the US stockmarket have been driven by AI companies. On Wall Street, chipmakers have contributed around 70% of the total gains in 2026 for the S&P 500, and Nvidia is now the index’s largest single company at about 8.06% of the index. This makes the market fragile. If investors begin doubting that OpenAI and similar customers can earn enough in revenue from customers to meet their commitments, Nvidia would be hit on two fronts. First, via lower expected sales and second via its financing exposure to those same companies. That would drag down the whole market, due to its heavy weighting in the key index. Australians would feel it too. Nearly 90% of households are exposed to AI stocks, due to the US shares held through their superannuation funds. A question of timing None of this means the AI boom is fake. The issue is timing. Nvidia, OpenAI and Firmus are betting that future revenue from users and businesses will grow fast enough to pay for today’s massive data centre build-out. Until then, investors, lenders and each other’s companies fill the financing gap. There is a historical comparison with the 1990s telecom boom. In what was then called the “New Economy”, equipment makers such as Cisco Systems financed customers to buy their equipment. Too much fibre was laid too soon, and investors lost heavily when the stock market bubble burst. But that fibre lasted decades. The newest AI chips have a shelf life of only a few years. If the expected revenue and demand from business and consumers arrives late or below forecasts, shareholders and super funds will bear the losses.
