Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed. Armed with this information, physicians may soon be able to develop more precise treatment strategies for neurological and psychiatric disorders.

For a disease afflicting 35.5 million people[1] in the U.S., chronic kidney disease flies under the radar. Only half the people who have it are formally diagnosed[2].

The consequences of advanced chronic kidney disease are severe. When these essential organs can no longer do their job[3] of filtering waste products from the blood, patients need intensive medical interventions that gravely diminish their quality of life.

Nearly every modern[1] medical treatment[2] can be traced to research funded by the National Institutes of Health: from over-the-counter and prescription medications that treat high cholesterol[3] and pain[4] to protection from infectious diseases such as polio and smallpox[5].

The remarkable successes of the decades-old partnership between biomedical research institutions and the federal government are so intertwined with daily life...
