Further Evidence

In case you missed the facts that our cats are named Adenosine Triphosphate (Addy) and Inosine (Nosey), that we spent four hours hashing out how to calculate the location of a moon on a planet's horizon, that we laughed at the interchangeable way "cancer vaccine" and "cancer drug" were used in Mary Higgins Clark's The Second Time Around, and that our Saturday morning channel of choice is The Discovery Channel, let me provide yet another clue confirming that Mark and Kellie are nerds. This was the gift Mark brought home for me from Cold Spring Harbor. And, as I put on the bracelet, Mark mentioned that he didn't get a chance to see if the helix had both a major groove and a minor groove. I promptly took off the bracelet to examine it, and we both concluded that it doesn't. It's still pretty cool, though.
