Alcoholism, smoking and genetics among Plains American Indians

..., "at least one third are social smokers who never progress to 'real' smoking, they just smoke in social settings. This may be a throwback to the traditional use of tobacco amongst American Indians." Enoch said that this study shows how there is no such thing as an "alcoholism gene" or "alcoholism allele....

Findings advance use of adult stem cells for replacement bone

...os said. "It's not unusual for adult stem cells to progress through a half-dozen or more stages of differentiation on their way to becoming the right tissue ?and any missed cue will derail the process. In most cases, engineers have little choice but to take a trial-and-error approach to designing a growth-fac...

"We have made great progress in our understanding of how antidepressants work, but despite years of research, our knowledge of the changes that these drugs induce in the brain is rudimentary," Bolanos said. "Though available treatments for depression are generally safe and effec...
