Healthy prion proteins spur the formation of brain cells, according to a new study published in the Proccedings of the National Academy of Sciences by Harvard-affiliated researchers. Prior to the study, which was conducted in the laboratory of MIT Professor Susan L. Lindquist at the Whitehead Institute in Cambridge, investigations had focused on the importance of the abnormal folding of certain prions, often associated with “mad cow” disease. This abnormal structure results in the inability of the proteins to be broken down by enzymes, and subsequently in the accumulation of the protein...
Since the 1990s, the ascendant mode of conservative American faith has been the megachurch. It gathers thousands, or even tens of thousands, for entertaining if sometimes undemanding services amid family-friendly amenities. It is made possible by hundreds of smaller "cell groups" that meet off-nights and provide a humanly scaled framework for scriptural exploration, spiritual mentoring and emotional support. Now, however, some experts look at groups like Jeanine Pynes' - spreading in parts of Colorado, Southern California, Texas and probably elsewhere - and muse, What if the cell groups decided to lose the mother church...
More recent arrangements can seem more ad hoc. Tim and Susie Grade moved to Denver a year ago. They had attended cell groups subsidiary to Sunday services but were delighted to learn that their new neighbors Tim and Michelle Fox longed for a house church like the ones they had seen overseas. Now they and seven other twenty- and thirtysomethings mix a fairly formal weekly communion with a laid-back laying on of hands, semiconfessional "sharing" and a guitar sing-along. Says Tim: "We have some people who come from regular churches, and were a little disenfranchised. And people...
...reasons that students supported Summers: he was passionately interested in their ideas and their experiences. He didn’t listen politely and then move on to the next student in line. Instead, he argued with students about every conceivable topic, from curricular reform to the ethics of stem cell research to the war in Iraq. Summers showed up at undergraduate events, and he meaningfully talked with students. He asked tough questions and then listened to thoughtful answers. He forced students into real conversations, short on platitudes and long on substance. Occasionally the students forced him onto the dance floor...
...they dominated the last technological revolution while Harvard stood by. Summers saw that for Harvard to keep its preeminence the University must play a more central role in the current biology-centered technological revolution. To that end, he championed initiatives like the Broad Institute and the Harvard Stem Cell Institute, endeavors which placed Harvard in the center of the life sciences. Inevitably, allocating resources to the life sciences meant conflict as other areas got less—or at least smaller increases in their budgets—but the only way to avoid conflict of this type is to have...
