Better than an extra-strength placebo?

Scientists at the Johns Hopkins University School of Medicine have published a new study (behind paywall - summary) on the effects of "magic mushrooms". Volunteers were given 4 doses of psilocybin spaced one month apart. The study built on previous work and attempted to optimize the experience for long-lasting positive effects:
61% of volunteers considered the psilocybin experience during either or both the [highest dosage] sessions to have been the single most spiritually significant of their lives, with 83% rating it in their top five. Consistent with this, 94% and 89% of volunteers, respectively, indicated that the experiences on those same sessions increased their well-being or life satisfaction and positively changed their behavior at least moderately.

Genes that cause depression?

A gene variant associated with serotonin transport (STG) , and normally associated with depression is strangely more prevalent, but also less likely to induce depression in collectivistic East Asian cultures. The study took data from 29 countries, and found a consistent trend towards this same genetic variant being strongly associated with episodes of major depression in Western cultures.
