The process of HIV infection is just one of the subjects protein researcher Dr. Ron Diskin is investigating in his new lab

“Deregulation scores” of hundreds of brain tumor patients: Each row corresponds to a pathway (that is, a biochemical process), and each column to a sample taken from a patient. Every colored spot stands for a number – the value of the “deregulation score” of the corresponding pathway, as determined for a particular patient. Dark blue stands for the activity of the pathway in normal brain tissue, whereas dark red indicates a high level of deviation from normal behavior. The clearly distinct group of normal b
