Global genome effort seeks genetic roots of disease
By decoding the genomes of more than 1,000 people whose homelands stretch from Africa and Asia to Europe and the Americas, scientists have compiled a detailed catalog of human genetic variation to find the genetic roots of rare and common diseases in populations worldwide.
The gene-environment enigma
A new study shows that the environment interacts with DNA in ways that are difficult to predict, even in simple organisms like single-celled yeast, which complicates the prospects for personalized medicine.
