Aftershocks following Saturday's magnitude-7.8 quake in Nepal are jangling nerves and complicating rescue operations. So far, there have been more than a dozen quakes of magnitude 5 or higher, and another two dozen between magnitude 4.5 and 5.

Maybe You Should Rethink That Daily Aspirin

Originally published on Mon April 27, 2015 1:48 pm

For all the good aspirin can do in preventing second heart attacks and strokes, taking it daily can boost some risks, too — of ulcers, for example, and of bleeding in the brain or gut.

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 wh have already experienced such an event or are at extremely high risk.

The Danger Of GMOs: Is It All In Your Mind?

Why do so many people oppose genetically modified organisms, or GMOs?

According to a new paper forthcoming in the journal Trends in Plant Science, it's because opposition to GMOs taps into deep cognitive biases. These biases conspire to make arguments against GMOs intuitive and compelling, whether or not they're backed by strong evidence.

Some murder cases are harder to solve than others. The investigation into the killing of Mellory Manning — a 27-year-old woman who was assaulted and murdered in 2008 while working as a prostitute in Christchurch, New Zealand — confounded police.

They conducted an investigation and interviewed hundreds of people, but months later, they still had no solid leads.

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.

But, even with all that, you could argue that the astronomer for whom the telescope is named made even more important discoveries — with far less sophisticated equipment.

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.
