POPSClues to Why We Dream at All ... In a recent paper in Psychological Bulletin, Dr. Nielsen and Dr. Levin proposed that dreaming served to create what they call “fear extinction memories,” the brain’s way of scrambling, detoxifying and finally discarding old fearful memories, the better to move on and make synaptic space for any novel threats that may show up at the door. “The brain learns quickly what to be afraid of,” Dr. Nielsen said. “But if there isn’t a check on the process, we’d fear things in adulthood we feared in childhood.” Ordinary bad dreams rarely recapitulate unpleasant events from real life but instead cannibalize them for props and spare parts, and through that reinvention, Dr. Nielsen explained, the fears are defanged. “A bad dream that doesn’t lead to awakening is successful in dealing with intense emotion,” he said. “It’s disturbing, but there is some kind of resolution to the extent we don’t wake up.” ...

I will then discuss the type of evidence that we would need to determine whether we exist in a simulation. Finally, I will describe two objections to the argument before concluding that while interesting, we should reject the Simulated Universe argument. This article is a critique on Nick Bostroms article Are You Living in a Computer Simulation?

POPSNoble or savage? We have been solving them, too. Pessimists will point out that each solution only brings us face to face with the next crisis, optimists that no crisis has proved insoluble yet.

POPSWay-new collaboration Howard Rheingold talks about the coming world of collaboration, participatory media and collective action -- and how Wikipedia is really an outgrowth of our natural human instinct to work as a group.
