Left-Handed Creativity Myth Debunked

The long-standing belief that left-handed people are more creative has been challenged by a new meta-analysis of over a century of research. After reviewing nearly 1,000 studies, researchers found no consistent advantage in creative thinking for lefties—in fact, right-handers slightly outperformed on some tests.

Overconfident Minds Fuel Belief in Fringe Conspiracy Theories

New research reveals that people who believe in conspiracy theories tend to be overconfident and unaware of how unusual their views really are. Across eight studies, participants who believed in false conspiracies consistently overestimated their performance on cognitive tests and thought the majority of others agreed with them—even when they were in a clear minority.

AI Writing Tools May Erase Cultural Nuances

New research shows that AI writing assistants can unintentionally homogenize global writing styles, pushing non-Western users to sound more American. In a study comparing Indian and American users, AI suggestions often promoted Western topics and writing patterns, diminishing Indian cultural expressions.

Blue Brain Marker Peaks in Midlife, May Predict Cognitive Aging

Researchers have mapped age-related changes in the brain’s locus coeruleus (LC), a region linked to cognition and Alzheimer’s risk, by tracking neuromelanin, a pigment that gives it its signature blue hue. In a diverse group of participants aged 19 to 86, they found an inverted U-shaped pattern: LC signal peaked in late middle age, then declined.

AI Teaches Robots Tasks from a Single How-To Video

Researchers have developed RHyME, an AI-powered system that enables robots to learn complex tasks by watching a single human demonstration video. Traditional robots struggle with unpredictable scenarios and require extensive training data, but RHyME allows robots to adapt by drawing on previous video knowledge.

Scent Signals Friendship: How Smell Shapes First Impressions

A new study reveals that women can subconsciously judge potential friendship compatibility based on scent during first-time meetings. Researchers found that a person’s everyday odor—captured on a worn T-shirt—predicted how much they were liked after short face-to-face conversations.

How Psilocybin Lifts Mood Without the Hallucinogenic Trip

Researchers have uncovered two key brain mechanisms—specific neurons and a serotonin receptor—that help explain how psilocybin produces long-lasting antidepressant effects. Their study identified pyramidal tract neurons in the medial frontal cortex and the serotonin 5-HT2A receptor as essential to the therapeutic action of psilocybin.

Ignoring Your Better Judgment Increases Regret and Self-Blame

A new study reveals that people feel more culpable when they follow bad advice than when they make poor decisions independently. Researchers found that going against one’s better judgment increases thoughts of missed opportunities, amplifying feelings of control and regret.

Pupil Dynamics During Sleep Reveal Brain’s Memory-Saving Secrets

Researchers have discovered that pupil size during non-REM sleep correlates with memory consolidation. When pupils contract, the brain focuses on consolidating new memories; when dilated, it processes older ones.

Tiny Walking Robots Advance Micro-Optics and Biological Research

Researchers have developed the smallest walking robots, measuring just 2 to 5 microns, capable of interacting with visible light for imaging and force measurement. These magnetically controlled robots can inch forward or swim through fluids while serving as diffraction elements, enabling super-resolution microscopy at scales previously unattainable.

Psychedelic Drug Reduces Anxiety by Targeting Fast-spiking Interneurons

The psychedelic DOI, a compound similar to LSD, reduced anxiety in mice by activating specific brain cells called fast-spiking interneurons. These neurons silence nearby cells in the ventral hippocampus, a region linked to emotion and memory. By uncovering this mechanism, the study opens the door to designing new treatments that target anxiety without triggering hallucinations, a hallmark of many psychedelics.
