You can't blame this one on McDonald's: Researchers have found signs of heart disease in 3,500-year-old mummies.
A new study raises fresh concerns about Zetia and its cousin, Vytorin — drugs still taken by millions of Americans to lower cholesterol, despite questions raised last year about how well they work.
EDITOR'S NOTE: Ten years and $2.5 billion in research have found no cures from alternative medicine. Yet these mostly unproven treatments are now mainstream and used by more than a third of all Americans. This is one in an occasional Associated Press series on their use and potential risks.
Men may protect more than their hearts if they keep cholesterol in line: Their chances of getting aggressive prostate cancer may be lower, new research suggests.

One quarter of Americans sick enough to be hospitalized with swine flu last spring wound up needing intensive care and 7 percent of them died, the first such study of the early months of the global epidemic suggests. That's a little higher than with ordinary seasonal flu, several experts said.
Fast-food places have them. Banks and pharmacies do, too. Now hospitals are opening drive-thrus and drive-up tent clinics to screen and treat a swelling tide of swine flu patients.
When the coughing stops is probably a better sign of when a swine flu patient is no longer contagious, experts said after seeing new research that suggests the virus can still spread many days after a fever goes away.
Researchers delivered a double dose of good news Sunday in the fight against flu: successful tests of what could become the first new flu medicine in a decade, and the strongest evidence yet that such drugs save lives, not just shorten illness.

Breast cancer patients with even the tiniest spread of the disease to a lymph node have a much higher risk of it recurring years later and may need more treatment than just surgery, new research suggests.
Americans spend more than a 10th of their out-of-pocket health care dollars on alternative medicine, according to the first national estimate of such spending in more than a decade.
