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.

Attention is the brain's filtering mechanism; what passes through that filter is what gets encoded. What gets encoded becomes memory. And memory is the raw material of identity. So in the architecture of your identity, attention is the doorway.

The fighting hypothesis proposes that there is a so-called frequency-dependent maintenance of left-handedness. The main idea is that over the tens of thousands of years of human evolution, left-handers did have an advantage in fights due to a surprise effect. This gives them an evolutionary survival benefit since they win more fights.

Just consider a typical day in the life of a modern human: you glance at your phone while waiting for coffee to brew, skim headlines while half-listening to a podcast, mentally rehearse a client pitch while walking your child to school, reply "noted" on Slack during a meeting while updating a slide deck, check your bank balance while standing in line,

As it turns out, neuroscience might be able to explain why. In a new study whose findings will surprise absolutely no one who's endured a fiery holiday dinner debate, researchers discovered that conservative and liberal brains don't just arrive at fundamentally different conclusions, but take strikingly different paths to get there. It's a fascinating piece of research which just might explain something about the yawning political divides currently tearing society apart.

Minutes into teaching my business school class, I asked what seemed like an innocent question: What is one word that describes how you feel about AI right now? One word. That's it. My students looked up, looked down, looked anywhere to avoid eye contact. Silence. "I promise," I said, "this is a safe space." Something I'd repeat throughout the course-and I meant it. Then the answers came quickly, and the energy in the room shifted as they arrived. You could feel the sheen of performance

You know that sinking feeling when you realize you've been using a phrase that makes you sound less intelligent than you actually are? I had one of those moments a few years back during a pitch meeting for my startup. I was presenting to potential investors, and I kept saying "I think" before every point I made. "I think our user acquisition strategy will work."

In 2013, when Meredith O'Connor was 16, the music video for her debut single "Celebrity" went viral. Afterward, she channeled her own stardom into championing childhood mental health: As a hyperactive kid, O'Connor says she was often the subject of bullying, and when her music career gave her a platform, she was eager to use it to advocate on behalf of other victims. "I knew my fan base was younger, but I didn't know how many people would resonate with mental health challenges," she says. "I realized there were millions of gifted people that are being marginalized, and that's when I really wanted to start the mental health study."

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.

Researchers studying brain-imaging data from people aged between 8 and 100 found that sex differences in the brain's connections are minimal in early life, but then increase drastically at puberty; some of these differences continue to grow throughout adult life. The study was published as a preprint on bioRxiv, and has not yet been peer reviewed. The work could help us to understand why men and women have different likelihoods of developing some mental-health disorders - and perhaps give insight into treating them, say the researchers.

Picture this: last weekend, while everyone was posting Instagram stories from crowded bars and house parties, I was curled up with a book about behavioral economics, completely absorbed. A friend texted asking if I was coming out, and when I said I was staying in to read, she replied with "You're such a nerd!" followed by a laughing emoji. But here's the thing-according to psychology research, my preference for books over parties might actually come with some serious intellectual perks.

For Plato, psyche meant something like what we'd now call mind -understood as a complex system requiring governance. The psyche had distinct parts: a reasoning part that deliberates, a spirited part that feels emotion and courage, and an appetitive part that desires. Each part has its own function and its own form of excellence. And crucially, these parts need to be governed-integrated under what Plato called constitutional self-rule.

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.

There are lots of reasons why relationships fall apart; all kinds of incompatibilities can doom romance. Some are trivial, but occasionally there might be something more profound at the root of an estrangement. Recently, the concept of the "frontal lobe breakup" appeared in popular culture. The idea is that the final stage of development in the executive regions of the brain-the frontal lobes-changes someone's perspective about their relationship. The onset of advanced cognitive skills in one partner creates a gap in maturity too big to bridge.

I am a worrier, and have been for most of my life. At some point, someone dear and smart teased me that I worry about the wrong things. The things that hit me, she noted, were never the things I worried about. For a while that left me feeling like an incompetent worrier-until my research caught up. I realized that the things I worry about often don't end up hurting me precisely because worrying helps me diffuse them ahead of time.

When I was a product marketing leader for a corporate regional bank, I found myself getting annoyed during an all-day strategy meeting. My frustration came from hearing the same voices, sharing the same old ideas. I wondered why other people, especially the women in the room, weren't speaking up. I remember thinking, "Well, you could be the one to speak up."

I've been thinking about this a lot lately, especially after reading Rudá Iandê's new book " Laughing in the Face of Chaos: A Politically Incorrect Shamanic Guide for Modern Life ". His insights about how "our emotions are not barriers, but profound gateways to the soul-portals to the vast, uncharted landscapes of our inner being" got me reflecting on imagination and how it shapes our inner worlds.
