...journal Neurology, a team led by Stephen Rao, a brain-imaging specialist, describes a study of 69 healthy men and women aged 65 to 85. The researchers divided the group into three: those who had no risk factors for Alzheimer's, those who had a family history of the disease but no genetic indicators of it themselves and those who had both family members with Alzheimer's as well as a version of a gene for a protein called apolipoprotein E4 (ApoE4) that has been linked to the condition. They slid all of the subjects into an fMRI machine...
...Albert Einstein and Marilyn Monroe, those who were at the highest risk of developing Alzheimer's - those with both the genetic makeup and a family history - showed high levels of activity in the hippocampus, posterior cingulate and regions of the frontal cortex, all areas involved in memory. The control group showed the opposite pattern. Their brains became more excited when they saw unfamiliar names, which included Irma Jacoby, Joyce O'Neil and Virginia Warfield...
That could mean that the at-risk people were working harder to recognize the well-known celebrities, compensating for already damaged or destroyed neurons that were no longer functioning, while the control group had to struggle only when trying to place the names of noncelebrities, recruiting more nerve cells and connections, racking their memory banks and recall centers.

...mother organization and champion of Hindu nationalist orthodoxy, to "take over" the party, implying that the only way the party could get its act together is to go back to the lock-step discipline of the RSS. This, however, would also entail a return to that group's ultra-nationalist values which would alienate Muslims,low-castes and religious minorities. The party now finds itself faced with a lingering existential question: whether to return to its core base and whole-heartedly embrace the RSS, or continue to project a more centrist image by distancing itself from Hindu fundamentalist dogma...
