A Molecular Claw....
a: Chelation ~
b: claw
What: "A lot of bacteria produce organic chelating compounds
called siderophores. Chelation is like a claw; it is how the
compound binds to metals such as iron, providing necessary
nutrients that help bacteria survive," Bullen said.
This is fundamental scientific research that hasn't been
examined much before, she added, explaining, "What we
had proposed was that these compounds might contribute
to why bacteria want to stick to a surface. If they're
on the outside of the bacteria, they could kind of act like
a claw and grab on to a surface..."

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.
