Highest average IQ is found within this ethnic group

It doesn't take a genius to recognize the vast number of contributions the people of Jewish ancestry have made in modern history. According to a 2005 scientific paper, "Natural History of Jewish Intelligence", Jews as a group inherit higher verbal and mathematical intelligence than other ethnic groups, on the basis of inherited diseases and the peculiar economic situation of Jews in the Middle Ages. Specifically, the Ashkenazi Jews - those who originated in Eastern Europe, such as Albert Einstein (left) and Carl Sagan (right) - tend to have higher intelligence than other ethnic groups; in fact, about 80% of modern Jews have Ashkenazi ancestry. One observational basis for inferring that Jews have high intelligence is their prevalence in occup ...

How to tell the best joke
|
view preview
According to a new study, it's your voice that is to blame if your joke ever falls flat. Researchers recorded men and women telling corny one-liners and then manipulated the pitches of their voices. Artificially lowered voices made the speakers sound more dominant; higher pitched voices made them sound less so. Volunteer listeners then rated each joke’s funniness. Female listeners laughed or groaned regardless of the comic’s voice pitch, but for men it depended on how burly and dominant they were. Guys with bigger biceps and higher self-rated attractiveness were more likely to prefer lower-pitched jokes than less dominant listeners, and vice versa, according to a study in press in Evolution and Human Behavior. The researchers suggest humor ...

How one perceives beauty is merely superficial

view preview
Beauty may be in the eye of the beholder, but what’s influencing our eye? Scientists reveal that it’s not genetics but life experiences that lead us to find one face more attractive than another. This finding furthers the on-going debate of nature versus nurture. Here's how the study went down: Researchers asked 547 pairs of identical twins and 214 pairs of same-gender fraternal twins to view 200 faces and rate them on a scale of one to seven, with one being the least attractive and seven the most attractive. A group of 660 non-twins then completed the same survey. If genes were more involved in facial preference, identical twins would have had similar ratings; if the influence of a familial environment carried more weight, fraternal twins w ...

Turns out that fish oil only benefits those who have the right genes
|
view preview
Most foods today are fortified with essential oils like omega-3 fatty acids. Naturally, these oils are found in fish, and are known to benefit many parts of the body, including the eyes, brain, heart, and joints. So, are these so-called beneficial oils important for people who lack the DNA profile needed to metabolise them? It turns out that the extra omega-3 might not do much good at all. According to a study published in Science, Inuit people living in Greenland whose traditional diet of fish and marine mammals have the right enzymes in their bodies needed to metabolise these foods that are very high fat content. The researchers reported that their DNA that was most different was on chromosome 11, specifically among genes that control the ...

Attention paleo dieters

A new study suggests that humans who live in industrialized societies don’t have the guts to stomach a real hunter-gatherer diet. Compared with hunter-gatherers, industrialized peoples’ intestines have fewer kinds of microbes - and are missing at least one major group of ancient bacteria.
