Health Research: Cannabis may be used to treat fractures ♦ The emerging science of human screams ♦ Potential treatment for Parkinson's disease discovered

Massive study: Birth order has no meaningful effect on personality or IQ For those who believe that birth order influences traits like personality and intelligence, a study of 377,000 high school students offers some good news: Yes, the study found, first-borns do have higher IQs and consistently different personality traits than those born later in the family chronology. However, researchers say, the differences between firstborns and 'later-borns' are so small that they have no practical relevance to people's lives
No bones about it: Cannabis may be used to treat fractures A new study explores another promising new medical application for marijuana. According to the research, the administration of the non-psychotropic component significantly helps heal bone fractures
The emerging science of human screams Our noisy world is no match for a screaming infant. An airplane could be flying by as a house party rages on downstairs while a literal cat fight takes place outside, and still a wailing baby will win your attention. One possible explanation is that human screams possess a unique acoustic property found to activate not just the auditory brain but also the brain's fear circuitry
Surprise: Subtle distractors may divert action more than overt ones What's more distracting, something overt or something subtle? We all know the right answer when it comes to perception, but in a new study, the less salient of two distractors had the greater power to affect an action.
Potential treatment for Parkinson's disease discovered Scientists have found that existing antimalarial drugs could be a potential treatment for Parkinson's disease. Parkinson's disease is a degenerative disorder of the central nervous system that causes a person to lose control of motor movements, such as the ability to move his or her hands, arms, and legs.
