A Moment of Science
Everyone knows that plants have some pretty good passive defense mechanisms. Learn about plants and their offensive strategies on A Moment of Science.
After digestion, glucose travels throughout the body in the blood stream. It enters all of our cells with the help of a hormone called insulin: insulin picks up the glucose and carries it into each cell, like a groom carrying a bride over the threshold.
The thing is that hair is a lot tougher than skin. So the same chemicals that destroy the hair can also cause serious skin irritation–and possibly even chemical burns–if left on too long.

Thanks to clothes moths and their fabric devouring larvae, your expensive Scottish wool sweater may one day resemble Swiss cheese.
The sweet taste of a substance has to do with how well the molecules that make up the substance chemically bind with the sweet taste receptors in our mouth. The amount of energy released when we metabolize this substance, is measured in calories.

One of the more puzzling consequences of old age is a decreasing ability to appreciate the taste of a fine meal. Actually, the problem is not only a matter of taste. It also has to do with smell. When we eat something, we rely on a combined sense of taste and smell to experience flavor. [...]
It’s commonly known than chopping onions will cause a person to cry. Well, you’re in luck if you frequently find yourself weeping over this smelly vegetable.
