Study reveals women who gave birth to girls had higher levels of cortisol in hair samples in the weeks before and at the point of conception. Read More
Researchers identify five biological indicators that have a significant impact on biological aging. Read More
Age, sex, and gender influence the organization of the brain's opioid system. Findings shed light on why there are significant differences between the opioid system on an individual level, and why some are more prone to developing opioid-linked pathologies than others. Read More
Combining fMRI and behavioral data, researchers examined gender identity in cisgender and transgender individuals using a new machine learning algorithm. The AI identified at least nine dimensions of brain-gender variation. Read More
Children as young as four associate power with masculinity a new study reports. Read More
According to a new study, men are twice as likely than women to consider themselves to be expert liars who can get away with being untruthful. One of the key strategies of liars is to tell plausible lies that are close to the truth, and not provide too much information. Read More
Incorporating sex (the biological attributes distinguishing males, females, or intersex individuals) and gender (psychological, social, and cultural factors which affect how a human identifies in society) could help improve scientific research, reduce bias and create new opportunities for innovation.

Stress and depression during pregnancy can affect the fetus' sex and increase the risk of preterm birth. Mothers who experienced physical and psychological stress during pregnancy were less likely to have a baby boy. During pregnancy, the fetuses of stressed mothers had reduced heart rate movement coupling, indicating slower central nervous system development. Read More
A circuit-specific gender difference in ventral hippocamps to nucleus accumbens (vHPC-NAc) neurons is dependent on testosterone and causes more susceptibility to stress in females. Read More
Schizophrenia is linked to alterations in pathways associated with glycosaminoglycan, neurotransmitter metabolism, and GABAergic synapses. A large percentage of genes related to schizophrenia are expressed differently between males and females. The results imply the mechanisms involved in schizophrenia development differ, at least slightly, between males and females. Read More
The risk of developing Alzheimer's disease is increased, and progression more rapid in women due to larger brain-wide accumulation and acceleration in the spread of tau. Read More
204 proteins discovered were more highly regulated in females than males, with 31% of the proteins being associated with the development of Autism, researchers report. Findings shed new light on why males are at higher risk of ASD than females. Read More
