Single high dose of the hallucinogen psilocybin, active ingredient of “magic mushrooms,” was enough to cause a measureable personality change lasting at least a year in nearly 60% of the 51 participants, according to a new study.
Personality was measured on a scientifically validated personality scale, which psychologists consider constituents of personality: openness, extroversion, agreeableness, neuroticism, conscientiousness.
Lasting change was found only in “openness,” which includes traits related to imagination, aesthetics, feelings, abstract ideas and general broad-mindedness.
Researchers will now explore possibilities of using psilocybin for helping cancer patients handle the depression and long-time cigarette smokers to overcome their addiction.
4.5 billion years of evolution taught nature what works and what lasts.
We’ve been increasingly distancing ourselves from nature: agricultural revolution – grow stock and abandon hunting/gathering; scientific revolution – “torture nature for her secrets;” industrial revolution – machines replace muscles.

FoldIt is a fun-for-purpose video game developed in 2008 by Uni Washington. In it gamers divide into competing groups and try to solve scientific puzzles using online tools.
They figured out the 3D structure of a monomeric protease enzyme, an essential protein in construction/replication of retroviruses, a family that includes HIV. Finding 3D structures of proteins allows to understand causes and potential cures of viruses.
Foldit creator Seth Cooper explained the success of gamers by saying:
People have spatial reasoning skills, something computers are not yet good at.
Until then only a 2D structure was known using microscopes.
