"The end of the pilus has a sticky protein on it, so to continue our metaphor, the pilus is like a telescoping antenna with a blob of crazy glue on the end. A twitching cell extends its pilus, sticks it to something, then draws it back in"
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
