➀ Researchers have identified a protein within the genetic code of fruit flies that can extend their lifespan by up to 30% when altered. ➁ The protein, F-actin, accumulates in the brain and slows down cellular cleaning, leading to waste build-up. ➂ The study suggests that manipulating F-actin could potentially extend human life.

➀ A study on Dutch twins found a slight genetic link between higher intelligence and reduced risk of psychopathology. ➁ The heritability of anxiety and negative affect was greatest in individuals with below-average intelligence. ➂ Common genetic factors that contribute to higher intelligence also appear to protect against certain mental health issues.
