That dreamers often lie
A massive effort to uncover genes involved in depression has largely failed. By combing through the DNA of 34,549 volunteers, an international team of 86 scientists hoped to uncover genetic influences that affect a person’s vulnerability to depression. But the analysis turned up nothing.
The results are the latest in a string of large studies that have failed to pinpoint genetic culprits of depression. […] Depression seems to run in families, leading scientists to think that certain genes are partially behind the disorder. But so far, studies on people diagnosed with depression have failed to reveal these genes.
