Research shows that the COVID-19 pandemic has accelerated brain aging by about five and a half months on average, even in individuals who did not contract the virus, likely due to stress, isolation, and uncertainty. The study suggests these changes might be reversible, and highlights the broader impact of environmental and social factors on brain health.
A study on male fruit flies reveals that repeated sexual rejection leads to increased activity, aggression, and anti-social behavior, indicating a frustration-like stress state mediated by the neuropeptide F signaling system in the brain. This social stress affects the flies' resilience to other stressors like starvation and toxic exposure, providing valuable insights into the neurobiological basis of social stress in a model organism.

The research offers insight into children’s social, psychological, and academic adjustment. The findings provide empirical evidence for long-standing ideas first articulated by the late Jerome Kagan several decades ago.
