Common Gene Variant Doubles Dementia Risk, But Only in Men

New research reveals that men who carry two copies of a common genetic variant in the HFE gene are more than twice as likely to develop dementia, while women with the same variant are not affected. The variant, known as H63D, is linked to haemochromatosis and is present in about 1 in 36 people.

Lab-Designed Peptide Targets Glioblastoma Stem Cells

A newly developed lab-designed molecule, JM2, may offer a promising therapy to combat glioblastoma recurrence by targeting the tumor’s most resilient cells. Researchers discovered that glioblastoma stem cells rely on the protein connexin 43’s interaction with microtubules—an interaction disrupted by JM2.

Caffeine Disrupts Sleep Brainwaves and Delays Nighttime Recovery

A new study reveals that caffeine increases the complexity of brain activity during sleep, especially in younger adults, potentially disrupting the brain’s ability to recover overnight. Researchers used EEG and AI to analyze sleep in 40 adults after caffeine or placebo intake, identifying less predictable brain signals and increased wake-like brainwave patterns.

Emotions Echo: Brainwide Timing Patterns Reveal Roots of Feeling

Emotions help guide our behavior, but when they persist too long or arrive at the wrong time, they can cause serious mental health issues. In a landmark study, researchers mapped brainwide activity patterns triggered by an unpleasant but harmless stimulus—eye puffs—in both humans and mice.

How Personality and Family Shape Athletic Self-Perception

A new study of Japanese undergraduates finds that students' perceptions of their own athletic ability are shaped by a mix of personality traits, childhood environment, and social feedback. Those who rated themselves as more athletic also tended to display grit, resilience, and a growth mindset. Factors like early walking age, athletic parents, frequent sports participation, and being called athletic by others were also linked to higher self-ratings.
