By Kitcher, Philip I There are simple and powerful arguments against the biological reality of race.1 Although the phenotypic characteristics, the manifest features that have traditionally been used to divide our species into races, are salient for us, they are superficial, indicating nothing about important differences in psychological traits or genetic conditions that constitute some racial essence. Throughout history, allegations of deep differences in temperament and capacity, claims...

WASHINGTON -- Scientists have found clusters of new gene variants that raise the risk of Type 2 diabetes - and how the researchers did it is as important as what they found. In one of the largest studies yet of human genetic variability, the scientists tested the DNA of more than 32,000 people in five countries to pin down spots that harbor genetic risk factors for this complicated killer. This type of research - called a "genome-wide association" study - promises to usher in a new era of...

Cambridge, MA, Wed., Oct. 26, 2005 "“ In several papers published this week in Nature, Nature Genetics, PLoS Biology and Genome Research, Broad researchers and an international set of collaborators announce substantial advances in relating human genetic variation to disease and understanding human evolutionary history. This flurry of high-profile studies are grounded in data described in a significant paper published in the Oct. 27 issue of the journal Nature by an international...

A comprehensive map of human genetic variation, published today in the journal Nature, is not only a major achievement by the International HapMap Consortium, but it also opens the door to future efforts that could pinpoint the changes that actually alter the way genes work, said the Baylor College of Medicine researcher who led the local HapMap effort. The HapMap itself, now in Phase I, will accelerate the search for genes that contribute to common diseases such as asthma, diabetes, cancer...

By Patricia Reaney LONDON -- A major scientific step in the field of genetics is set to speed up the search for the causes of common illnesses ranging from heart disease and cancer to Alzheimer's and asthma, researchers said on Wednesday. They have completed a map that charts patterns of human genetic variation in the world population, to better understand human biology, evolution and how to diagnose diseases. "It is a scientific milestone because it now links directly to the human genome...
