Coffee L inked to Lower Dementia Risk
Drinking coffee may do more than just keep you awake. A new study suggests an intriguing potential link to mental health later in life, as well.
A team of Swedish and Danish researchers tracked coffee consumption in a group of 1,409 
middle-age men and women for an average of 21 years. During that time, 61 participants developed dementia, 48 with Alzheimer’s disease.
After controlling for numerous socioeconomic and health factors, including high cholesterol and high blood pressure, the scientists found that the subjects who had reported drinking three to five cups of coffee daily were 65 percent less likely to have developed dementia, compared with those who drank two cups or less. People who drank more than five cups a day also were at reduced risk of dementia, the researchers said, but there were not enough people in this group to draw statistically significant conclusions.
Dr. Miia Kivipelto, an associate
professor of neurology at the Karolinska Institute in Stockholm and lead author of the study, does not as yet advocate drinking coffee as a preventive health measure. “This is an observational study,” she said. “We have no evidence that for people who are not drinking coffee, taking up drinking will have a protective effect.”
Dr. Kivipelto and her c
olleagues suggest several possibilities for why coffee might reduce the risk of dementia later in life. First, earlier studies have linked coffee consumption with a decreased risk of type 2 diabetes, which in turn has been associated with a greater risk of dementia. In animal studies, caffeine has been shown to reduce the formation of amyloid plaques in the brain, one of the hallmarks of Alzheimer’s disease. Finally, coffee may have an antioxidant effect in the bloodstream, reducing vascular risk factors for dementia.
Dr. Kivipelto noted that previous studies have shown that coffee drinking may also be linked to a reduced risk of Parkinson’s disease.
The new study, published this month in The Journal of Alzheimer’s Disease, is unusual in that more than 70 percent of the original group
of 2,000 people randomly selected for tracking were available for re-examination 21 years later. The dietary information had been collected at the beginning of the study, which reduced the possibility of errors introduced by people inaccurately recalling their consumption. Still, the authors acknowledge that any self-reported data is subject to inaccuracies.

Breaking Distant Light Credit: VIMOS, VLT, ESO
Explanation: In the distant universe, time appears to run slowly. Since time-dilated light appears shifted toward the red end of the spectrum (redshifted), astronomers are able to use cosmological time-slowing to help measure vast distances in the universe. Above, the light from distant galaxies has been broken up into its constituent colors (spectra), allowing astronomers to measure the redshift of known spectral lines. The novelty of the above image is that the distance to hundreds of galaxies can now be measured on a single frame using the Visible MultiObject Spectrograph operating at the Very Large Telescope array in Chile. Analyzing the space distribution of distant objects will allow insight into when and how stars, galaxies, and quasars formed, clustered, and evolved in the early universe.

SOFT CELL- Where was your Heart when you Need it Most
You're time-wasting again
Biting your nails like you were sixteen
Putting up your little walls
When emotion's around
Leave your little heart
In the lost and found
Your friends would die laughing
If they saw you this way
Even though they cry the same tears every day
Where was your heart
When you needed it most?
Hand in hand with your innocence
Gave up the ghost
But it doesn't do to tell
You're at your best
When you're living hell
Just put on your hard face
You know you do that so well
Thank god you wore
Your waterproof make-up today
And who gives a damn about him anyway?
To him you're a body
And to hell with the mind
But you get the same stick from his type all the time
Just a couple of drinks
And they've got you tonight
And you know the sad thing
Is that they're often right
Where was your heart
When you needed it most?
Hand in hand with your innocence
Gave up the ghost
They take hold of your heart
And they spit it right out
Make a show of their conquest
When their friends are about
Your ego deflated
You gave up the fight
And became the good-time-had-by-all-every-night
And where was your heart
When you needed it most?
Hand in hand with your innocence
Gave up the ghost
No comfort of beds
Or the softness of sheets
Just the back of a car
Sprawled across the back seats
And he'll just not give up
And he's messed up your head
A dish in the disco
But a pig in the bed
So you build up a false love affair anyway
Photocopy soap opera stories all day
Where it all ends up fine
And it all ends in church
And the girl looks like you
And she never really gets hurt
And where was your heart
When you needed it most?
Hand in hand with your innocence
Gave up the ghost
Biting your nails like you were sixteen
Putting up your little walls
When emotion's around
Leave your little heart
In the lost and found
Your friends would die laughing
If they saw you this way
Even though they cry the same tears every day
Where was your heart
When you needed it most?
Hand in hand with your innocence
Gave up the ghost
But it doesn't do to tell
You're at your best
When you're living hell
Just put on your hard face
You know you do that so well
Thank god you wore
Your waterproof make-up today
And who gives a damn about him anyway?
To him you're a body
And to hell with the mind
But you get the same stick from his type all the time
Just a couple of drinks
And they've got you tonight
And you know the sad thing
Is that they're often right
Where was your heart
When you needed it most?
Hand in hand with your innocence

Andrew Wyeth, Realist and Lightning Rod, Dies at 91
Andrew Wyeth, one of the most popular and also most lambasted artists in the history of American art, a reclusive linchpin in a colorful family dynasty of artists, and a painter whose precise, realist views of a harsh rural life became emblems of national culture and incited endless debates about the nature of modern art, died on Friday at his home in Chadds Ford, Pa. He was 91.
"Winter" - 1946
"Christian's World" - 1948
"Wind from the Sea" - 1947
