As a journalist who covers AI, I hear from countless people who seem utterly convinced that ChatGPT, Claude, or some other chatbot has achieved "sentience." Or "consciousness." Or-my personal favorite-"a mind of its own." The Turing test was aced a while back, yes, but unlike rote intelligence, these things are not so easily pinned down. Large language models will claim to think for themselves, even describe inner torments or profess undying loves, but such statements don't imply interiority.

"We behave differently when we're anxious or when we're experiencing fear, versus when we are feeling courageous. And mice do the same," explained Alexandra Klein, postdoctoral researcher at UCSF, during a lab tour, adding that there are multiple experiments conducted in the lab to analyze a mouse's behavior - all this to understand human brain functions better and potentially cure diseases. The tour even showcased a real mouse brain in a test tube.

Researchers have launched a search engine that can quickly sift through the staggering volumes of biological data housed in public repositories. The team integrated data from seven publicly funded data archives, creating 18.8million unique DNA and RNA sequence sets and 210billion amino-acid sequence sets that users can search through using text prompts. The search engine, called MetaGraph, can also uncover genetic patterns hidden deep within expansive sequencing data sets without needing those patterns to be explicitly annotated in advance.

Recent advances in neuroscience indicate that the dorsomedial prefrontal cortex plays a central role in rapidly evaluating potential romantic partners, often without conscious awareness. Key findings show that specific regions within this cortex are responsible for making swift assessments, and these neural patterns can reliably predict whether someone will express romantic interest or decide to pursue further interaction after just a brief encounter.

He'd make things up that didn't happen. Then he'd get angry when questioned, as if remembering was an attack on him. Every time she brought up something he did wrong, suddenly the conversation became about her mental health, her past trauma, her inability to let things go. She started writing everything down because she couldn't trust her own memory anymore. When he found her journal, he said it proved she was paranoid.

Sometimes, you can be talking to someone for hours, and it feels like only a few minutes. You natter and natter without ever having to think of what to say or cringe through any awkward silence. There's a gentle sway to things - you listen, they speak, they listen, you speak. The chat dances to the easy and comfortable rhythm of the conversational tide.

Gonzalo de Polavieja, 56, is exasperated by the ease with which many people opine on topics without knowing anything about them. A neuroscientist trained at Oxford and Cambridge, with a PhD in quantum physics and a postdoctoral degree in mathematical neurobiology, he is currently on leave from Spain's CSIC research center and directs the Laboratory of Mathematics of Behavior and Intelligence at the Champalimaud Foundation in Lisbon, where he studies how groups of animals including humans organize themselves.

As I've shared before, when I was 12, I was playing at a friend's house one hot August afternoon when I was told I was needed at home. As I turned into my long driveway, I saw the lights of an ambulance, a stretcher being loaded into the back. The doors slammed shut. The whirling lights threw red streaks across the oaks as it sped past me out of our driveway. No one noticed the small, pale, immobilized girl standing by the mailbox.

You've seen it on T-shirts, Instagram captions, and coffee mugs: "Good vibes only." But is it just a trendy phrase or is there real science behind the power of positive thinking? As it turns out, there is. Neuroscience shows what many of us instinctively feel: staying optimistic, practicing gratitude, and spreading kindness can do more than just lift your mood. They can actually change how your brain works, and even influence your long-term health. Let's take a closer look at how positivity affects the brain, and how you can train your mind to be more resilient, optimistic, and happier.

Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging. At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

This summer, I did something unusual for me: I hit pause. After a year that included launching an in-person summit for nearly 200 women, hosting a retreat in Cabo, launching my podcast (with co-host Dr. Nicole Martin), and releasing a book, I was, in a word, tired. The kind of tired that no amount of coffee or color-coded planner could fix.

In a previous post, I described the life of Heinz Lehmann, a young German physician who fled the rise of Nazi power and settled in Canada, where he played a major role in the recognition of chlorpromazine as a treatment for psychoses. As it turns out, he was one of many talented physicians and scientists who settled in Britain, the U.S., and Canada, where they contributed to the growth of neuroscience and neuropharmacology.

We tend to think that we experience the world as it is. We see and hear things, store them away as knowledge, and then take new facts into account. But that's not how our brains actually work. In reality, we filter out most of what we experience, so that we can focus on particular points of interest. In effect, we forget most things so we can zero in on what seems to be most important.

'I got woken up by a massive thump on the shoulder. So I opened my eyes, and I could see next to my bed a very vague hazy version of Robin as if he was pushing himself through treacle to be seen, and I was just transfixed, and I could see him become more and more clear, I could see the outline of his hair and his face, but he suddenly just dissolved from the top down.'

Children's brains are more attuned to unusual details instead of familiar patterns, resulting in high scores for intuition, unlike older individuals who rely on established patterns.

Erin Kunz of Stanford University indicates that brain-computer interfaces (BCIs) can restore speech for paralyzed individuals by decoding signals from the brain's motor cortex, revealing intended speech.

An agent or team member lacking reasoning, adaptability, and perspective integration operates only in a narrow lane, remaining ineffective in dynamic environments.

Tim Gregory notes that the most climate-concerned environmentalists are often the least supportive of nuclear power, despite its potential to mitigate global warming through zero carbon emissions.
