'Personality genes' may help account for longevity Posted: 24 May 2012 06:53 PM PDT Researchers have found that personality traits like being extroverted, enjoying laughter and staying engaged may also be part of the longevity genes mix that allows some people to reach age 100 and beyond.

Categories for kinship vary between languages Posted: 24 May 2012 11:34 AM PDT Different languages refer to family relationships in different ways. For example, English speakers use two terms -- grandmother and grandfather -- to refer to grandparents, while Mandarin Chinese uses four terms. Many possible kinship categories, however, are never observed, which raises the question of why some kinship categories appear in the languages of the world but others do not. A new study shows that kinship categories across languages reflect general principles of communication.

Positive words: The glue to social interaction Posted: 24 May 2012 08:23 AM PDT Words charged with a positive emotional content are used more frequently, thus enhancing human communication.

More physical education in schools leads to better grades, study suggests Posted: 23 May 2012 08:47 AM PDT More physical education in schools leads to better motor skills and it can also sharpen students' learning ability, new research shows. The differences are especially clear among boys.
