Walking away from church

By Robert D. Putnam and David E. Campbell

The most rapidly growing religious category today is composed of those Americans who say they have no religious affiliation. While middle-aged and older Americans continue to embrace organized religion, rapidly increasing numbers of young people are rejecting it.

So, why this sudden jump in youthful disaffection from organized religion? The surprising answer, according to a mounting body of evidence, is politics. Very few of these new "nones" actually call themselves atheists, and many have rather conventional beliefs about God and theology. But they have been alienated from organized religion by its increasingly conservative politics.

Evangelical Protestantism, which saw dramatic growth in the 1970s and 1980s, has been hit hard by this more recent development. From the early 1970s to the late 1980s the fraction of Americans age 18 to 29 who identified with evangelical Protestantism rose to 25% from 20%, but since 1990, that fraction has fallen back to about 17%. Meanwhile, the proportion of young Americans who have no religious affiliation at all rose from just over 10% as late as 1990 to its current proportion of about 27%.

Sebastian Seung: I am my connectome

In the brain, neurons are connected into a complex network. Sebastian Seung and his lab at MIT are inventing technologies for identifying and describing the connectome, the totality of connections between the brain's neurons -- think of it as the wiring diagram of the brain. We possess our entire genome at birth, but things like memories are not "stored" in the genome; they are acquired through life and accumulated in the brain. Seung's hypothesis is that "we are our connectome," that the connections among neurons is where memories and experiences get stored. Seung and his collaborators, including Winfried Denk at the Max Planck Institute and Jeff Lichtman at Harvard University, are working on a plan to thin-slice a brain (probably starting with a mouse brain) and trace, from slice to slice, each neural pathway, exposing the wiring diagram of the brain and creating a powerful new way to visualize the workings of the mind. They're not the first to attempt something like this -- Sydney Brenner won a Nobel for mapping all the 7,000 connections in the nervous system of a tiny worm, C. elegans. But that took his team a dozen years, and the worm only had 302 nerve cells. One of Seung's breakthroughs is in using advanced imagining and AI to handle the crushing amount of data that a mouse brain will yield and turn it into richly visual maps that show the passageways of thought and sensation.

Atheists, agnostics most knowledgeable about religion, survey says

By Mitchell Landsberg, Los Angeles Times So why would an atheist know more about religion than a Christian? American atheists and agnostics tend to be people who grew up in a religious tradition and consciously gave it up, often after a great deal of reflection and study, said Alan Cooperman, associate director for research at the Pew Forum. "These are people who thought a lot about religion," he said. "They're not indifferent. They care about it." Atheists and agnostics also tend to be relatively well educated, and the survey found, not surprisingly, that the most knowledgeable people were also the best educated. However, it said that atheists and agnostics also outperformed believers who had a similar level of education. http://www.latimes.com/news/nationworld/nation/la-na-religion-survey-20100928,0,3225238.story
