The Bay Area and local news media got an inside view of research at the California Regional Primate Research Center June 9, a day before a traveling group of animal activists named the 1999 Primate Freedom Tour stopped on campus. In the photo at right, Jeffrey Roberts, center, assistant director of the primate center, talks to reporters and camera operators about how research focuses on human health problems such as AIDS, reproduction, osteoporosis, Alzheimer's disease, asthma and the health impacts of environmental pollutants. The rhesus monkey is anesthetized before receiving a bone-density scan as part of an osteoporosis study. On Saturday, six animal activists were arrested during a protest at the center.
