...evenly among blacks, Hispanics and a category containing whites and Asians. Hybels' Willow Creek is at 20% minority. Megachurches serve only 7% of American churchgoers, but they are extraordinarily influential: Willow Creek, for instance, networks another 12,000 smaller congregations through its Willow Creek Association. David Campbell, a political scientist at Notre Dame studying the trend, says that "if tens of millions of Americans start sharing faith across racial boundaries, it could be one of the final steps transcending race as our great divider" - and it could help smooth America's transition into a truly rainbow nation.

...These were people in the problem-drinker category," says lead researcher John Cunningham, senior scientist with the Canadian Center on Addiction & Mental Health. He explained that before they used the website, subjects were typically consuming 22 alcoholic drinks per week. "They drink enough to risk health consequences but are not severely dependent...
Biologists offer this analogy as an explanation: if the genome is the hardware, then the epigenome is the software. "I can load Windows, if I want, on my Mac," says Joseph Ecker, a Salk Institute biologist and leading epigenetic scientist. "You're going to have the same chip in there, the same genome, but different software. And the outcome is a different cell type...
...contrast, Darwin argued that evolution works not through the fire of effort but through cold, impartial selection. By Darwinist thinking, giraffes got their long necks over millennia because genes for long necks had, very slowly, gained advantage. Darwin, who was 84 years younger than Lamarck, was the better scientist, and he won the day. Lamarckian evolution came to be seen as a scientific blunder. Yet epigenetics is now forcing scientists to re-evaluate Lamarck's ideas. (See TIME's video on Charles Darwin and Abraham Lincoln...
Another strength of the ADDM network is that it allows researchers to track autism rates over time. For the current study, Catherine Rice, a behavioral scientist at the CDC's National Center of Birth Defects and Developmental Disabilities, compared data from 10 sites in 2002 with the latest figures from 2006 - using a consistent definition of ASD - to determine that the prevalence of ASD had increased...
