The Aging Brain
by Katharine Dunn
Neuroscientists have long used damaged brains as a way to understand normal brain functions. But doing the opposite also works. A group of researchers at Harvard recently looked at the effects of aging on healthy people’s brains and found that as we get older, communication between different brain regions breaks down. This discovery could eventually help scientists better characterize and detect neurodegenerative diseases, including Alzheimer’s, which affects more than 5 million Americans.
The younger brain, below, shows more synchronized activity than the older brain, above.
Until recently, most scientists looking at the aging brain focused on individual regions, especially those in the frontal lobe, which may shrink or lose activity even in the absence of disease, says Jessica Andrews-Hanna, a doctoral student in psychology at Harvard’s Center for Brain Science and the lead author on the group’s paper (published last December in the journal Neuron). Though other investigators had hypothesized that disconnections might occur in the ebb and flow of signals between regions, it wasn’t easy to measure this until the introduction in the early 1990s of functional magnetic resonance imaging (fMRI), a scanning technique that measures blood flow.

Have you ever thought of keeping live fish at home? No, not the usual little goldfish turning tight circles in a bowl little larger than a jam jar - I mean starting an aquarium.

You will have to spend a bit of time on it to begin with, and even some money, but you will find it worthwhile. See some of the popular and colorful pet fish below.
Tornadoes Cut Destructive Path Across Central U.S., Killing 22

SENECA, Missouri — Stunned survivors picked through the little that was left of their communities Sunday after tornadoes tore across the Plains and South, killing at least 22 people in three states and leaving behind a trail of destruction and stories of loss.
At least 15 people died in southwestern Missouri. In the fading mining town of Picher, Okla., at least six people were killed, and at least one person died in storms in Georgia.
Susan Roberts, 61, stared at the smashed remains of her classic 1985 Cadillac sitting on her living room floor — the only thing left of her Seneca home. A woman who had apparently sought shelter in the car died there, she said.
