New
Study: Chocolate Can Keep Heart in Shape
 For
those who think the world is a bitter place, medical science offers
this sweet health tidbit: Chocolate might be good for you.
Not
just any chocolate, and always in moderation, said Mary Engler, a
professor of physiological nursing at the University of California,
San Francisco, School of Nursing. But her new study does find that
biting into the right stuff can make arteries expand, increasing blood
flow and thus reducing cardiovascular risk.

Few
Seeking Medicare-Approved Drug Cards
 As
Tuesday's starting date has arrived for the Medicare drug discount
program, the number of older Americans enrolling for the new benefit
has been disappointing, according to some card sponsors.
While
most of the more than 70 sponsors are silent about how many people
they've signed up, AARP admits its number is minuscule. The group,
which has 35 million 50-and-older members, mailed out 26,000
enrollment kits and has signed up only 400 people.
Learn
about why initial enrollment goals may not have been met, qualifying
requirements and how you can help educate qualified seniors that
aren't enrolled on CNN's

Mad
Cow Hunt Begins, But Will the Testing Work? 
The
cow brains should arrive any day now. If all goes as planned, dozens
of plastic-bagged specimens each day will be delivered from
surrounding states. Technicians will stick on a bar code, and
delicately slice a sliver of neural tissue, which will be puréed into
a pink slurry and fed into a $150,000 robot. After a few hours, tiny
samples -– now mere dabs of liquid -- will tell a crucial tale. If
the samples are clear, all is well. If yellow tints appear, the
country may have another case of mad cow disease.
MSNBC
has provided extensive information on the FDA's new plan of action to
prevent the spread of Mad Cow in the U.S., as well as criticism
regarding questions about a potentially flawed and ineffective system.
American
Heart Association: Air Pollution is Serious Cardiovascular Risk
 Exposure
to air pollution contributes to the development of cardiovascular
diseases, according to a new American Heart Association scientific
statement published in today’s print issue of Circulation:
Journal of the American Heart Association.
“The
increase in relative risk for heart disease due to air pollution for
an individual is small compared with the impact of the established
cardiovascular risk factors such as high blood pressure or high
cholesterol. However, this is a serious public health problem
due to the enormous number of people affected and because exposure to
air pollution occurs over an entire lifetime,” said Robert D. Brook,
M.D., lead author of the statement and an assistant professor of
medicine in the Division of Cardiovascular Medicine at the University
of Michigan in Ann Arbor.
