Depression traced to overactive brain circuit
A brain imaging study finds that an emotion-regulating brain circuit is overactive in people prone to depression – even when they are not depressed. Even when in remission, most subjects with a history of mood disorder experienced a temporary recurrence of symptoms when their brains were experimentally sapped of tryptophan, the chemical precursor of serotonin, the neurotransmitter that is boosted by antidepressants. The finding suggests that tryptophan depletion unmasks an inborn trait associated with depression.

Study shows how consensus is attained in a noisy world
Seventy thousand people gathered in Leipzig, East Germany, on Oct. 9, 1989, to demonstrate against the communist regime. Clearly, no central authority planned this event; so how did all of these people decide to come together on that particular day? A new study by Northwestern University researchers sheds light on how individuals might obtain information about the decisions and preferences of other individuals with whom they do not have a relationship or even contact.
