  • The article Your brain might be hard-wired for altruism” details two separate experiments which suggest altruism may be hard wired. Both were published.

    Experiment 1

    “It’s almost like these areas of the brain behave according to a neural Golden Rule,” Christov-Moore said. “The more we tend to vicariously experience the states of others, the more we appear to be inclined to treat them as we would ourselves.”

    Experiment 2
    “Normally, participants would have been expected to give according to need, but with that area of the brain dampened, they temporarily lost the ability for social judgments to affect their behavior,” Christov-Moore said. “By dampening this area, we believe we laid bare how altruistic each study participant naturally was.”

    Appears to suggest there was natural selection pressure for homo sapiens, probably as a result of tribal living, to be more generous, and that those that were, passed on more genes than the more selfish.

    Another small nail in the coffin of the religious myth that only true believers can be morally good, and idea that particularly appalls me. How dare you say I am a bad person.

  • Perhaps we should add this new information from NASA’s Dawn probe to the list!

    The US space agency’s Dawn satellite continues to return remarkable images from the dwarf planet Ceres.

    *Now just 385km above the surface (lower than the space station is above Earth), the probe has revealed new features inside the mini-world’s Occator Crater.

    This is the 92km-wide depression that has multiple bright spots of what are thought to be exposed salts.

    The new imagery reveals a dome in a smooth-walled pit in the centre-most bright area of the crater.

    With a resolution now of 35m per pixel, Dawn can make out numerous fractures that cut across the top and down the flanks of this dome.
