Students Ryan and Lucas in Chemistry II are analyzing common household products to predict and test them for pH litmus paper readings, labelling them as an acid or base.

Not only do soda pops have acid in them, many have caffeine which can prevent your bones from absorbing calcium just as the phosphoric acid in caramel-colored pops do.  They also contain sugars which can harm your teeth.

 (CNN) -- Two American scientists won the Nobel Prize in chemistry Wednesday for their work revealing protein receptors that tell cells what is going on in and around the human body. Their achievements have allowed drug makers to develop medication with fewer side effects.

Research spanning four decades by Robert J. Lefkowitz and Brian K. Kobilka on "G-protein-coupled receptors" has increased understanding of how cells sense chemicals in the bloodstream and external stimuli like light, according to the Royal Swedish Academy of Sciences, which awarded the prize.

Lefkowitz began the research by tracking adrenalin receptors. The Nobel Prize announcement apparently set off some of the excitement hormone in his own body.
