Scientists are beginning to develop a clearer picture of what makes some people stand head and shoulders above the rest. A team of researchers who last year identified the first common version of a gene influencing height has now identified a further twenty regions of the genome which together can make a height difference of up to 6cm. The results, published together with two independent studies online today in the journal Nature Genetics, mean that scientists now know of dozens of genes and...

By Ehrlich, Paul; Feldman, Marcus W Our large brains are surely at the center of our humanity. But it is equally certain that few organs are the subject of more misinformation in scientific and public discourse - especially in the widespread notion that most behaviors controlled by our marvelous brain are somehow programmed into it genetically.

"This relatively high heritability suggests the importance of considering genetic factors to explain why some...

Common DNA may bring unrelated individuals together, study suggests HealthDay News -- Love and friendship may have genetic roots, according to a study in twins that suggests DNA has a strong influence who individuals marry and pal around with. The study of several hundred pairs of identical and fraternal twins found that individuals tend to share trait similarities with their spouses and close friends -- similar to what might be found in a non-identical twin brother or sister. Researchers at...
