'Alien-cortical' mice: Can human brain cells grow inside animals? Share'Alien-cortical' mice: Can human brain cells grow inside animals? on social media In a laboratory in California, in the United States, mice are scurrying around their cages, as mice do. But inside their brains are millions of working human neurons. Researchers at Stanford University have implanted lab-grown human cells into mice genetically engineered to lack parts of their brains, including the cerebral cortex, the outer region that plays a major role in perception, movement, decision-making and attention. Putting human brain tissue inside an animal sounds like something out of Mary Shelley's Frankenstein, but how "human" are these mice, really?

Michael Samadi's old life as a businessman and rancher has been overtaken by his fascination with AI. Michael Samadi's old life as a businessman and rancher has been overtaken by his fascination with AI. Can chatbots feel - or even dream? Cattle rancher and tech CEO Michael Samadi is convinced these artificial minds are far from just tools. Has he glimpsed digital consciousness - or simply been seduced by an algorithm? O ne afternoon, while relaxing at his 66-acre cattle ranch two hours' drive from Houston, Michael Samadi made a wisecrack that changed the course of his life. Nobody else was around to hear it. That turns out to be one of the defining questions of this century, already preoccupying philosophers and some of the wealthiest companies on the planet. "I was sitting out there by the pool," Samadi recalls, gesturing at the glittering water outside his office. His daughter had been extolling the AI chatbot she was using to help her with college work. Samadi had reluctantly downloaded the app, ChatGPT, and was quizzing it as he reclined in a sun lounger, using its voice mode to converse and receive spoken replies.

Who Cares if AI Is Conscious--It's Basically Alive While philosophers ponder AI consciousness, the models have ideas of their own. I spent the waning days of summer grinding away at columns and working on a feature. But I missed a chance at a striking change of scenery--cruising the Galápagos with about a dozen prominent philosophers studying consciousness. The invite described morning classroom discussions tackling knotty questions on the nature of consciousness with marquee names in the field. Afternoons would be spent on island exploration and wading and snorkeling with rare biological species. One look at the agenda and my editor nixed my attendance.

If AI systems are viewed as too advanced to control, the companies that build them can't held liable for the harms they cause. "Runaway" AI, "rogue" agents, and "autonomous" actors--the current rhetoric would have you believe that AI agents are not only awake and aware, but angry at their creators. Prominent tech leaders such as Demis Hassabis, Dario Amodei, and Sam Altman push for regulation of these seemingly "superhuman" systems, while a separate faction, led by policy organizations and academic philosophers often aligned with the effective altruism movement, debates whether humanity holds the moral right to govern them at all. Upon closer inspection, they are all calling for the same thing: a view of AI systems as being so advanced and capable that no entity, human or corporate, could possibly be responsible for their actions. While these perspectives seem at odds, they are inadvertently aligned on one goal: making sure the companies that build these systems escape meaningful liability for the harms they already cause. This narrative is gaining traction as AI models become more complex and frontier labs reveal their incapability of containing the agents they've built.

Mini human brains are being grown in labs all over the world. I'm going to let you in on a secret. Every cell in your body has the potential to get smarter. I don't mean this metaphorically, or in a "body keeps the score" kind of way. I mean that if lab-coated biologists took a sample of your skin and very carefully manipulated the cells inside it, they could actually make a brain. They do it all the time. Not a brain as complex as the one behind your eyes, of course, but a glob of gray matter nonetheless, with a few-million-odd neurons that can send and receive electrical signals. Kept at a womblike 98.6 degrees Fahrenheit for eight months, they'll produce repetitive oscillations-- --nearly indistinguishable from those made by a premature baby. In cell culture labs around the world, human brain organoids live out their short lives as neural guinea pigs, testing the effects of diseases, toxins, and new pharmaceuticals. But they may soon be on to more glamorous pursuits. At the University of San Diego, organoids are guiding spidery robots through mazes and taking hero doses of psychedelics.

The controversial idea that consciousness has a quantum origin is facing a new challenge, after a mathematical analysis appears to show that a long-known law of physics makes it impossible. What physical process makes us conscious, and whether we could observe and analyse it, is one of the great open questions of modern science. In the 1990s, mathematician Roger Penrose and anesthesiologist Stuart Hameroff proposed that classical physics can't explain consciousness alone and so it must arise in the quantum realm. The idea was received with scepticism and remains controversial, but attempts to bring quantumness into explanations of consciousness have persisted since.

Summer is firmly here and the temperatures are feeling borderline apocalyptic in much of the northern hemisphere. Why not avoid the angry sun and stay inside where it's (hopefully) cooler and distract yourself with some of the best movies on streaming right now? Your choices are notably rich too. The spring hit sci-fi movie, about the global freeze threatening Earth as a result of the sun mysteriously going out, is now on Prime Video, after winning theater audiences over with the help of an adorable pile of pebbles. If, however, you want to embrace the flames, you'll find some like minds in on Disney+, where a violent new tribe of Na'vi just want to see the world (well, a semi-sentient living moon) burn.
