Consider the human body or that of a mouse, where everything is in sync with the master biological clock. As part of a pre-clinical study that could eventually help drug addicts, researchers at the University at Buffalo removed that clock from mice. Then they gave the mice an injection of methamphetamine, a stimulant, and provided a running wheel. Methamphetamine and running both target the same reward centers in the brain and are addictive for mice. After six weeks, researchers found that the circadian…
