When we handwrite, especially something as emotionally loaded as a thank-you note, our brains engage in what neuroscientists call "embodied cognition"-the physical act of writing actually shapes how we think and feel about what we're expressing. The people I wrote to started responding differently. Not just polite acknowledgments, but genuine, heartfelt replies that often led to deeper conversations.

Rumination activates the default mode network (DMN) - the brain's self-referential processing system. This is the neural circuitry that fires when you're thinking about yourself in relation to others: your identity, your social standing, your mistakes. It's the brain asking, over and over, What does this say about me?

Neuroscientists have a name for the brain network that fires up when you're not focused on an external task: the default mode network, or DMN. It's the constellation of regions - the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus among them - that hums to life when you daydream, reflect on yourself, or think about other people's mental states.

When you enter a social situation - especially one with more than two or three people - your brain doesn't just "engage." It activates a staggeringly complex monitoring system. You're tracking facial microexpressions, calibrating your tone, predicting how your words will land, adjusting posture, managing silence, interpreting ambiguity. All of it simultaneously. All of it unconsciously.

At the Winter Olympics, skiers, bobsledders, speedskaters, and many other athletes all have to master one critical moment: when to start. That split second is paramount during competition because when everyone is strong and skilled, a moment of hesitation can separate gold from silver. A competitor who hesitates too much will be left behind -but moving too early will get them disqualified.

London-based deep tech startup Stanhope AI has closed a €6.7 million ($8 million) Seed funding round to advance what it calls a new class of adaptive artificial intelligence designed to power autonomous systems in the physical world. The round was led by Frontline Ventures, with participation from Paladin Capital Group, Auxxo Female Catalyst Fund, UCL Technology Fund, and MMC Ventures. The company says its approach moves beyond the pattern-matching strengths of large language models, aiming instead for systems that can perceive, reason, and act with a degree of context awareness in uncertain environments.

An elephant's trunk is a marvelous thing, flexible enough to bend and stretch as it forages for food, but also stiff enough to grasp and maneuver even delicate objects like peanuts or a tortilla chip. That's because the trunk is highly sensitive when it comes to sensing touch. Scientists have determined that the whiskers lining the trunk are crucial for that sensitivity thanks to their unique structure, amounting to a kind of innate "material intelligence, according to a new paper published in the journal Science.

Could he be right? I think so, but partly because it doesn't take much to clear a low bar-there haven't been many exciting drugs for alcohol addiction. The last one was approved twenty years ago, and it was really just an injectable version of a medication that first came on the market during the Reagan Administration. Meanwhile, alcohol-related deaths in the U.S. have roughly doubled in those decades.

We try to understand and grow it, but many of us cannot. This is not because we are damaged or less than. It is because our body feels unsafe. This is especially true for self-kindness, which is one of the domains of self-compassion. Offering ourselves kindness when our internal systems feel stretched out, out of control, and unworthy is simply not a possibility for most of us at this stage.

According to Thomas C. Corley's research, 76% of millionaires exercised for at least 30 minutes a day, four days a week. Yeah, exercise. Not exactly the secret formula you were expecting, right? Why movement matters more than you think I used to think successful people were too busy for the gym. Turns out, I had it backwards. They're successful partly because they make time for it.

Dr Jared Cooney Horvath, a former teacher-turned-neuroscientist, revealed that the generation born between 1997 and the early 2010s has been cognitively stunted by their over-reliance on digital technology in school. Since records have been kept on cognitive development in the late 1800s, Gen Z is now officially the first group to ever score lower than the generation before them, declining in attention, memory, reading and math skills, problem-solving abilities, and overall IQ.

Northwestern University has launched the Simpson Querrey Brain Health Institute (SQ-Brain), made possible by nearly $25 million in philanthropic funding from university trustee Kimberly K. Querrey ('22, '23 P). SQ-Brain envisions a future where our brains last as long as our bodies a world where brain health is continuously measurable, modifiable and monitorable across the lifespan, and where prevention of cognitive decline and brain injury is anchored in neurovascular biology and precision medicine.

In a recent talk in Zurich, German psychoanalyst Konstantin Roessler surveyed the current state of dream research. Tracing some of the earlier scientific studies on dreams, he made a renewed case for the importance of dreams. Even formerly skeptical neuroscientists have now begun to see the meaning, purpose, and value of dreams for everyday life and overall psychic health. Dreams as Meaningless "Content"

For most of my life, I thought of myself as a fixed entity: This is me. These are my traits. This is who I am. I assumed I was essentially that same person who loved sugary cereal at age 8, fried chicken at 12, and tequila at 21, and who still loves those things now, even if my stomach disagrees. But this is an illusion. Neuroscience, physics, and Buddhism all agree: There is nothing fixed about us-not even close.

One day during his first term, Donald Trump summoned a top aide to discuss a new idea. Trump called me down to the Oval Office,' John Bolton, national security adviser in 2018, told the Guardian. He said a prominent businessman had just suggested the US buy Greenland ' The US president's friend Ronald Lauder, heir to the Estee Lauder cosmetics fortune, is now making deals in the island. Guardian investigations correspondent Tom Burgis explored the reasons behind Trump and Lauder's fixation with Greenland. Read more

In response to threats by US President Donald Trump to somehow acquire Greenland (Kalaallit Nunaat), US scientists have drafted what they call a statement in solidarity with the island, open to any US-based researchers who have conducted research there. "A lot of people in the US - not just scientists - are very upset about the rhetoric directed towards Greenland. But scientists who work there feel it very personally," says paleoclimatologist Yarrow Axford, who is one of the creators of the initiative.

With the use of a bootstrap experimental setup consisting of a large polystyrene ball, a curved computer monitor, and a small straw that dispenses sugar water, Tóth managed to teach a rat how to play the classic 1994 video game Doom II. The rat's movements translated into rotations of the ball, which were then translated into movement inside the iconic first-person shooter. The sugar water served as a treat whenever the rat completed a milestone, like walking down a corridor.

The brain's main task is to minimize the gap between expectation and reality. This gap is what the Free Energy Principle defines as free energy. When the brain encounters unpredictable input, its stress level rises. And it's crucial to understand: this isn't about you as a person or a "user", it's about your brain. It's not something we consciously control, but it's something we can use.

"[My train of thought] let its line down into the stream. It swayed, minute after minute, hither and thither among the reflections and the weeds letting the water lift it and sink it until-you know the little tug-the sudden conglomeration of an idea at the end of one's line."

Neuroscience and sports psychology (for example, acceptance and commitment therapy) show that anxiety, perfectionism, and fear of mistakes shrink cognitive flexibility and creativity. The more we obsess over results, the more our attention collapses into the future. This focus makes us less present with what is happening now. As mental performance coach Graham Betchart puts it: "Stress is the absence of presence."

Seneca, the ancient Stoic philosopher, wrote in Letters to Lucilius that it's not the man who has too little, but the man who craves more, that is poor. The film "Fight Club" delivered the modern remix centuries later when Tyler Durden-played with feral brilliance by Brad Pitt-growled: The things you own end up owning you. One was writing in imperial Rome. The other was railing against the Ikea-ification of the modern soul. Yet both saw the same truth: Desire, when unquestioned, becomes bondage.

Fundamentally, they are based on gathering an extraordinary amount of linguistic data (much of it codified on the internet), finding correlations between words (more accurately, sub-words called "tokens"), and then predicting what output should follow given a particular prompt as input. For all the alleged complexity of generative AI, at their core they really are models of language.

Most people could tell you that Francis Crick, together with James Watson, discovered the double helix structure of DNA, and shaped our understanding of how genes work. Fewer know that Crick also played a key role in modern neuroscience and inspired our continuing efforts to understand the biological basis of consciousness. Crick once said the two questions that interested him most were the borderline between the living and the non-living,

In philosophy, physicalism is the idea that everything can be explained in physical terms. Whether through atoms, electrons, quarks, fields, or other physical processes, physicalism holds that every phenomenon ultimately depends on the physical world. In the philosophy of mind, this means that everything about the mind can, in principle, be explained by the physical processes of the brain. We don't yet know all the details, but physicalism maintains that a complete explanation is possible.
