Social foraging strategies illustrate the balance between competition and cooperation, where individuals either produce resources or exploit the efforts of others, navigating ecological and social constraints.

Galen Buckwalter, a 69-year-old research psychologist and quadriplegic, participated in a brain implant study to contribute to science that aids those with paralysis. The six chips in his brain decode movement intention, allowing him to operate a computer and feel sensations in his fingers again.

They created an artificial 'mental map', with pleasantness along one axis and bodily reactions along the other, and charted how the brain responded while watching clips from films. The results revealed clear groupings in the way that our brains represent emotion - with guilt, anger and disgust in one corner and happiness, satisfaction and pride in the other.

That's how long our physiological response to emotions such as anger lasts, from the time we formulate a thought to the point at which our blood is completely clean of the noradrenaline released in response to it. If you're still experiencing emotional reactions after 90 seconds, you're rethinking the thoughts.

According to the Free Energy Principle (FEP), developed by theoretical neuroscientist Karl Friston and colleagues, much of what the brain does can be understood as minimizing such mismatches—a technical form of 'surprise' defined as the improbability of sensory input given an internal model. The proposal brings perception, action, learning, and decision-making under a single framework.

Hyperphantasia is a cognitive trait characterised by an abundance of vivid mental imagery. In an area of developing science (the term was only coined a decade ago), those who identify with this experience have an imagination of lifelike quality and can create detailed images and scenarios in their minds. It can also extend to multiple senses.

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.

The Brain Science Here's where neuropsychology enters the vineyard. The human brain's relationship with wine is deeply emotional and multisensory. When we taste wine, our orbitofrontal cortex integrates sensory information with memory and emotion; it's why a particular bottle might remind us of our grandmother's kitchen or that study-abroad summer in Tuscany. This neural complexity is what makes wine special, and it's also what makes AI's role in the industry controversial.

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.

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.

If you have ever experienced proper rejection and that would be most of us it may stand out in your mind for a long time, like a boulder lodged in the landscape of memory. And it can hurt literally. The late anthropologist Helen Fisher, who studied human behaviour in the context of romantic love, showed that rejection and physical injury have much in common.

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"
