Molecule-size particles are entering the food chain through processed foods and their packaging. Nanotechnology can help make products creamier without additional fat, as well as intensify and improve flavors and brighten colors.

Their small size allows nanoparticles to go places in the body that larger particles can’t reach–they even enter our cells (the Environmental Protection Agency is evaluating nanoparticles used in sunscreens). In April, the Food and Drug Administration issued an warning about them, saying it did not have enough data to assume they are safe in food.

It kills you if you eat it and it kills you if you DON’T eat it. What’s that? Processed food from "fast food" franchises. A new study suggests that burger restaurants release more particulates into the air than most commercial trucks.

And holding your breath while walking past your local hamburger joint won’t solve the problem: According to the EPA, exhaust from nearby buildings, such as restaurants, can enter your home and create a dangerous level of indoor air pollution.

Quantum entanglement, which Albert Einstein called "spooky action at a distance," occurs when two atomic particles are split apart, but still INSTANTLY copy each other–no matter HOW far away from each other they are (NOTE: Subscribers can still listen to this show).

Scientists speculate that tiny atomic particles–the building blocks of the universe–come in six different flavors. But they’re so tiny that if you tasted one, would you even notice?
