Studying synapses in live human brains is crucial for understanding many psychiatric disorders. Now, using positron emission tomography of the brain of patients with psychiatric disorders, researchers from Japan have developed and used a novel technology to visualize the distribution of AMPA receptors, one of the most important molecules in synaptic transmission. Their efforts could lead to more accurate diagnosis and targeted treatments for diseases like schizophrenia, bipolar disorder, and autism spectrum disorder.

New research reveals a strong link between higher female education and lower fertility rates in sub-Saharan Africa. Educated women are driving a shift toward smaller families and even influencing less educated peers. This new forecasting model offers policymakers valuable insights into how women's education shapes population trends, aiding sustainable development efforts.

Researchers from Osaka University found that Highly Sensitive Persons (HSPs) in the workplace experience significantly higher levels of stress compared to their non-HSP colleagues. Approximately 26% of working adults could be classified as HSPs, indicating that a substantial portion of the workforce might be experiencing higher levels of stress. Interestingly, HSPs also exhibit greater empathy, suggesting that their heightened sensitivity enables them to connect deeply with others, potentially fostering a more supportive work environment.
