We've all heard that an aspirin a day can keep heart disease at bay. But lots of Americans seem to be taking it as a preventive measure, when many probably shouldn't.
In a recent national survey, more than half the adults who were middle age or older reported taking an aspirin regularly to prevent a heart attack or stroke. The Food and Drug Administration only recommends the drug for people who've already experienced such an event, or who are at extremely high risk.

The Hubble Space Telescope this week celebrates 25 years in Earth's orbit. In that time the telescope has studied distant galaxies, star nurseries, planets in our solar system and planets orbiting other stars.

It's springtime in Pittsburgh, and throughout the city, Callery pear trees are sprouting beautiful, white blossoms.
But that's just the problem. Simply put, these trees stink.
"This whole place smells like dead fish," says Sheila Titus. "I mean everywhere. Everywhere you see one of these trees with the white on them."
Titus has lived in her home in the now-hip neighborhood of Lawrenceville for 49 years. Two decades ago, her grandson and his 7th grade class planted a row of Callery pears across the street from her house.
