I've had a cookie sheet for a long time. Last month, my dishwasher broke and I forgot about the few dishes that were still inside, including my cookie sheet. I also didn't know that the repair guy left water in the bottom of machine. Water that could get really gross.

Long story short, the dishwasher got very gross and smelly over the course of a month, and when I went to clean the cookie sheet, it was covered with some sort of mold. Not entirely covered, but in quite a few places. And when I tried cleaning the pan, the low pressure coming from the faucet was enough to start stripping off the nonstick lining on the pan. It just started peeling off. And it did that in a few places, so I decided to throw it away.

The question is: What ate my cookie sheet, and should I be worried about the rest of my dishware? What about my health?

I'm a senior in high school about to graduate in a few months, I plan to do a major research for my senior final involving the study of p53 and its affects on cancer growth. Ideally, I would need the help of a local university professor (SFSU) although I want to be sure what I'm doing so I could have a little more confidence with how to deal with state-of-the-art lab materials. What are the equipments used to study molecular proteins? How do you use it and finally analyze the results? Anyone with a Life Science background are more than welcomed to contribute! :-)
