An international consortium of researchers published a macro-study in the journal Nature on Wednesday identifying 1,260 distinct genetic variants that influence human personality. [^1]

The researchers determined the genetic component of personality by comparing identical twins with fraternal twins. [^2]

The study found that 824 of the identified 1,260 genetic variants have never before been linked to personality traits. [^3]

A new study published in the journal Nature found that watching live sports reduces the stress hormone cortisol and increases the social-bonding hormone oxytocin. [^4]

A recent Australian paper reviewed many studies and concluded that children engaging in risky outdoor play showed better overall mental health and social abilities. [^5]

A study involving 19 countries found that water-centric blue spaces like rivers and oceans bring feelings of restoration, calm, and greater mental and emotional energy. [^6]

Researchers state that collective effervescence, the feeling of closeness experienced in positive group activities like concerts, can provide uplift that continues for up to a week. [^7]

The study suggests that personality traits such as curiosity, ambition, responsibility, and kindness have a genetic component that is shaped by these variants. [^8]
