Cooper pairs of fermions are thought to be responsible for the bizarre properties of superconductors (such as their total lack of resistance) and of superfluids (such as lack of viscosity and a strange, quantized flow within vortices). Achieving Cooper pairing in fermion condensates would enable scientists to examine the properties of Cooper pairs with unprecedented flexibility and would help unravel the enduring mysteries of the physics behind superconductors.

From CNN

Starting this month, Song, the new low-cost flyer from Delta, will debut its new in-flight workout program.

For $8 passengers will get an elastic band, a squeezable ball and a how-to manual with a workout designed by fitness guru Dave Barton.

Song isn't the only airline aiming to keep you fit in flight. For the past several months Jet Blue has offered in-flight yoga, and more recently, Pilates.

It's too soon to tell whether the new workouts will give you "buns of steel," but when it comes to exercise, something's better than nothing. What's more, experts say that regular physical activity, especially on long flights, can help prevent deep vein thrombosis (DVT).

This is my first posting on my first blog site.

From New York Times
People who do not want to wait for old age to shrink their brains and bring on memory loss now have a quicker alternative - abuse methamphetamine for a decade or so and watch the brain cells vanish into the night.

The first high-resolution M.R.I. study of methamphetamine addicts shows "a forest fire of brain damage," said Dr. Paul Thompson, an expert on brain mapping at the University of California, Los Angeles. "We expected some brain changes but didn't expect so much tissue to be destroyed."

The image, published in the June 30 issue of The Journal of Neuroscience, shows the brain's surface and deeper limbic system. Red areas show the greatest tissue loss.

The limbic region, involved in drug craving, reward, mood and emotion, lost 11 percent of its tissue. "The cells are dead and gone," Dr. Thompson said. Addicts were depressed, anxious and unable to concentrate.

The brain's center for making new memories, the hippocampus, lost 8 percent of its tissue, comparable to the brain deficits in early Alzheimer's. The methamphetamine addicts fared significantly worse on memory tests than healthy people the same age.
