Why Pain Lingers Longer in Women

It’s not in your head; it’s in your immune system. Scientists discover the biological "off-switch" that explains why chronic pain persists longer for women.

Early Brain Activity Differences Predict Addiction Risk in Boys vs Girls

A large-scale analysis of nearly 1,900 children found that those with a family history of substance use disorder show early differences in how their brains transition between activity states, long before any drug exposure. Girls with family history showed increased transition energy in introspective networks, suggesting greater difficulty shifting out of internal, stress-linked states.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Brain Circuit Found to Shape Risk and Impulse Differently by Sex

Researchers exploring risky decision-making in rats found that a specific reward-related neural circuit influences impulsivity and risk-taking in complex ways that depend on timing and biological sex. Manipulating the circuit during the learning phase of a gambling task altered risky choices differently in males and females, while manipulation after learning affected motor impulsivity in both.

Sex Shapes the Course of Bipolar Disorder and Schizophrenia

A large multicenter study has revealed that sex influences the course and characteristics of schizophrenia and bipolar disorder. Women with schizophrenia tended to begin treatment later, while men with schizophrenia had the highest rates of substance use.

Early Autism Traits Show No Sex Differences in Toddlers

A large-scale study of over 2,500 toddlers found no significant clinical differences in autistic traits between males and females at the time of early diagnosis. Conducted over two decades, the study used comprehensive assessments across language, motor skills, cognitive traits, and social behaviors.

Protein Differences Between Sexes Aren’t All Genetic

An international study of 6,000 proteins across 56,000 people found that while protein levels differ significantly between males and females, most of these differences are not caused by genetics. Only about 100 proteins showed sex-specific genetic regulation, suggesting that environmental, hormonal, and lifestyle factors play a major role in shaping health outcomes.

Histamine Alters Dopamine Differently in Male and Female Brains

Sex differences in neurological disorders like Tourette syndrome, schizophrenia, and ADHD may stem from how histamine affects dopamine in the brain. A new mouse study reveals that histamine decreases dopamine in males but increases it in females, with the female response influenced by the estrous cycle.

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.
