Your Genes Influence What You Smell

A major genetic study of over 21,000 Europeans has identified 10 regions in the genome linked to how we perceive specific odors—seven of which are newly discovered. Three of these genetic regions function differently in men and women, helping explain hormone-driven changes in smell sensitivity.

Spreading Brain Waves Drain Neuron Energy

Researchers have, for the first time, tracked how individual neurons lose and recover energy during spreading depolarizations — waves of electrical disturbance linked to brain disorders like stroke. Using genetically modified mice and real-time fluorescent microscopy, the team visualized adenosine triphosphate (ATP) levels in neurons under both healthy and stroke-like conditions.

First Full Map of Fruit Fly Nervous System Reveals Sex Differences

Scientists have completed the first full connectome of the adult fruit fly, including both the brain and ventral nerve cord, revealing how neural signals travel between these two structures. This breakthrough uncovers never-before-seen neurons in the neck that transmit brain commands to the body.

This shows people surrounded by screens.

Brain Learns to Tune Out Distractions with Repeated Exposure

Our brains can adapt to filter out repeated distractions, according to a new EEG study. Participants learned to ignore frequent visual distractions, such as a red shape in the same location, while searching for a target.

Neuroticism Amplifies Negative Emotions and Mood Fluctuations

Researchers discovered people with higher neuroticism, a trait potentially risking mental health, experience not only amplified negative emotions but also higher mood variability. Using a novel approach from Bayesian statistics, the psychologists analyzed 13 longitudinal datasets to confirm their findings.
