peterofoz writes "The students will be asked to voluntarily submit a DNA sample. The cotton swabs will come with two bar code labels. One label will be put on the DNA sample and the other is kept for the students' own records. The confidential process is being overseen by Jasper Rine, a campus professor of Genetics and Development Biology, who says the test results will help students make decisions about their diet and lifestyle." No word in the story on just what "confidential" means — who will have access to the results, how long they'll be kept, or what else they might someday be used for. Will the notoriously liberal Berkeley campus see this as a service or an invasion of privacy?
