Testosterone-Aggression Link: How Shame Proneness Affects Responses to Social Exclusion

Social exclusion, an experience that can pose threats to an individual's status and dominance, can lead to various behavioral responses potentially mediated by changes in testosterone levels. This study found that those with low levels of shame proneness showed heightened aggression when experiencing a rise in testosterone post-exclusion, whereas those with decreased testosterone demonstrated lower aggression.

Testosterone’s Dual Role in Brain Development: Affects Emotion Control Differently Across Ages

Higher testosterone levels influence emotion control differently during adolescence and adulthood. Using brain imaging, they discovered a positive impact of testosterone on the engagement of the brain's anterior prefrontal cortex (aPFC) decreases from age 14 to 17, then flips by age 20.

‘Love Hormone’ Oxytocin Could Mend a Broken Heart

Oxytocin, a hormone connected with bonding and love, could help to heal damage following a heart attack. Researchers found oxytocin stimulates stem cells from the heart's outer layer and migrates into the middle layer where it develops into muscle cells that generate heart contractions. This could be used to promote the regeneration of heart cells following a heart attack.
