A new kind of calculus

I love science because it is interesting, ever-expanding and based on facts.    This morning there is a piece in the LA Times which describes the analysis of plaque, also known as calculus, on the teeth of Neanderthals.

There is also evidence that they consumed tree bark, which contain the ingredients in aspirin, which may have helped pain management close to 50,000 years ago. Cool beans…
