Why Labeling GMO Food Is a No-Brainer

Bring up genetically engineered foods, and most people focus on the obvious but most vexing questions: are they safe to eat? Or how might they make me sick? Such questions and the inability of current science to provide clear answers, have triggered a polarizing debate about labeling of a scale unprecedented in the history of food labeling.

When It's Time to Fill Your Cavities, All Options Are Toxic

When your dentist finds a cavity, besides the immediate fear of the drill or the painful pinch of the novocaine injection, the choice of filling material can also raise anxieties.

The full health significance of these events is still being debated, as government and academic monitoring programs generate a patchwork of data about their impact. And while many studies show that the risks from nuclear power are negligible in the U.S., these two catastrophes continue to raise questions about long-term safety and the cumulative affect of small and large releases of radioactive material. Meanwhile, researchers are attempting to track these contaminants in the food chain, in our bones and even in baby teeth.
