Antidepressant response within hours, or a blind alley? Experts weigh evidence on ketamine as a fast-acting treatment for depression in Harvard Review of Psychiatry.
Recent studies suggest that ketamine, a widely used anesthetic agent, could offer a wholly new approach to treating severe depression—producing an antidepressant response in hours rather than weeks.… [read more]

About 30-40% of depression is genetic in origin. A really interesting study just published outlines a new and rather dramatic look at this aspect of depression.

Wisdom is currently one of the most hotly researched aspects of human cognition. I have flagged much of this research in past issues of TR. It’s increasingly important because it is that which we humans have over machines and whether you have it or not will dictate your chances in the ever more competitive job market of the future (competitive between humans and machines that is).… [read more]
After a wage increase, people tend to be more satisfied with their jobs—and even more so when what they have gained exceeds the wage increases of their colleagues. Yet, this effect on job satisfaction is not persistent. Two economics professors reported these findings in a study recently published in the Journal of Economic Behavior & Organization.… [read more]
