It's a common phrase; money can't buy happiness.   But a worldwide survey of more than 136,000 people in 132 countries that included questions about happiness and income revealed that life satisfaction certainly does rise with income, though it seems to depend on how you define happiness because positive feelings don't necessarily follow, the researchers report.  

It may be a fundamental part of the human condition that few are content, no matter what they have.  The findings, from an analysis of data gathered in the first Gallup World Poll, appear this month in the Journal of Personality and Social Psychology.

Politicians and education activists believe computer access is creating a generation of "have not" students that will be unable to compete in a digital world.  Their very expensive solution is to guarantee subsidize home computers and even high-speed Internet service.

It may not only be incredibly expensive but also a bad idea for the poorest kids, according to a new study by Duke University's Sanford School of Public Policy, who say such efforts would actually widen the achievement gap in math and reading scores. Students in grades five through eight, particularly those from disadvantaged families, tend to post lower scores once these technologies arrive in their home.

Of the 27% of respondents who decided to go into the private sector, the majority went into the business or financial

Proteins are the workhorses of our existence.   These "helmsmen of the cell" are composed of amino acids, whose sequence is already defined by the heritable information in every living being and transport substances, convey messages and carry out vital processes in their role as molecular machines. 

The translation of this information during the production of proteins (protein synthesis) is determined by the genetic code and 20 amino acids form the standard set of which proteins are built.

Men will sometimes blame hormones for how women act but it isn't just one gender - one thing that sets off hormone changes in men is competition, says a new PNAS study.

The average man experiences hormone changes similar to the henpecked bonobo prior to competition, but a more competitive man undergoes changes more like those found in a chimpanzee, say researchers from Duke and Harvard universities.  Chimpanzees live in male-dominated societies where status is paramount and aggression can be severe but in bonobo culture a female is always the most dominant and tolerance can allow for more flexible cooperation and food-sharing.
