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.
Tiny RNA Mark Helps Explain Brain Wiring and Mental Disorders
New research reveals how a tiny chemical mark on RNA helps wire the brain during development. Scientists discovered that m6A methylation regulates the production of proteins essential for axon growth, including APC and β-actin.
Brain Tracks Emotional Transitions Through Music
New research reveals how the brain navigates emotional transitions, using music as a tool to map changing neural patterns. Scientists found that emotional responses in the brain depend heavily on the listener’s prior emotional state.
People Prefer Human Empathy, Even When AI Says the Same Thing
A new study shows that people rate empathic responses as more supportive and emotionally satisfying when they believe they come from a human—even if the same response is AI-generated. Across nine experiments with over 6,000 participants, responses labeled as human were consistently seen as more genuine, especially when they involved emotional sharing and care.
Mimicking Exercise in the Brain Could Slow Cognitive Decline
While physical activity is known to slow cognitive decline in Alzheimer’s disease, many patients are unable to exercise due to frailty or advanced symptoms. A new study identifies a specific gene, ATPPIF1, that is reactivated through exercise and supports neuroplasticity in the brain.
Alzheimer’s May Disrupt Nerve Insulation Without Reducing Myelin
New research reveals that Alzheimer’s disease may impair nerve function not by reducing myelin, but by altering the proteins at the critical interface between axons and their myelin sheath. Scientists found structural abnormalities in the paranode region, where myelin attaches to axons, including clogged nutrient channels and protein buildup that could block signal transmission.
