By Ann Baldwin and Marc Bekoff MEDICAL and biological research relies heavily on studies of lab animals such as mice and rats. These are often inbred strains, and are kept in “standard” cages so that different groups can be compared – animals missing a particular gene are compared with those that don’t, for example, or animals given a drug with those that aren’t. But there is one confounding factor for which researchers appear to have a blind spot – stress. Scientists seem to think that as long as animals are kept in roughly comparable conditions,
