Animal Intelligence and the Evolution of the Human Mind

The human brain lacks conspicuous characteristics—such as relative or absolute size—that might account for humans’ superior intellect. This article in Scientific American is a smoothly written and interesting discussion of how scientists have found ways to measure intelligence in non-human species--especially primates--and of the speculation on the reasons behind human intelligence.

Girls = Boys at Math

There's no real difference between the scores of U.S. boys and girls on common math tests, according to a massive new study. Educators hope the finding will finally dispel lingering perceptions that girls don't measure up to boys when it comes to crunching numbers.

"This shows there's no issue of intellectual ability--and that's a message we still need to get out to some of our parents and teachers," says Henry "Hank" Kepner, president of the National Council of Teachers of Mathematics in Reston, Virginia.

It won't be a new message

Smart Girls Eat Fish

Girls who eat more omega-3 fatty acids outsmart those who eat higher amounts of omega-6 fatty acids, according to new research. As a result of this and other studies, government dietary recommendations--especially those aimed at pregnant women--should emphasize fish over soy and corn oils, which are respectively high in these fatty acids.

Women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children

Higher Suicide Risk for Smart Doctors

There's a grim, rarely talked-about twist to all that medical know-how doctors learn to save lives: It makes them especially good at ending their own. An estimated 300 to 400 U.S. doctors kill themselves each year — a suicide rate thought to be higher than in the general population, although exact figures are hard to come by.

Study proves that intelligence can be a detriment to survival in some species

Okay, it's been fairly obvious for some time that humans' large and shapely brains involve some kind of evolutionary tradeoff. What is it, a third or a fourth of our blood flow that goes directly to the brain? I don't know. Well, this study shows that intelligence does not always increase an organism's odds for survival. Fruit flies bred to learn faster and surer were consistently larva-slapped by their troglodytic brethren.

Smarty Gene: Breast-fed kids show DNA-aided IQ boost

Scientists have achieved a breakthrough in deciphering the genetics of intelligence. Ironically, they did it by accounting for a key environmental factor.

Smart people earn income; steady people generate wealth

Darkfrog submitted, created time 1 year 6 months (www.sciam.com)

This article seems to explore the assumption that smart people make more money, but what it's actually doing is explaining the difference between income and wealth. People with high IQ's, it says, make more money per year (income) but don't necessarily accumulate more wealth (assets minus debts).

In general, the people who become wealthy are those who spend less than they make and invest regularly. That sounds pretty smart to me, but then, one doesn't have to have an IQ over 130 to figure it out

Mozart doesn't make you clever

Luneetty submitted, created time 1 year 7 months (www.nature.com)

German government decides to tackle the myth of the 'Mozart effect'. Passively listening to Mozart — or indeed any other music you enjoy — does not make you smarter. But more studies should be done to find out whether music lessons could raise your child's IQ in the long term, concludes a report analysing all the scientific literature on music and intelligence, which was published last week by the German research ministry. Even if the effect of musical training is confirmed in future studies, he concedes, it is highly unlikely to make your child a genius.
