Graether, a post-doctoral fellow in biochemistry, also works on the 
microscopic scale, looking at how nature arranges the atoms of the 
antifreeze proteins, which inhibit ice growth.

First discovered more than 30 years ago, the proteins were shown to prevent 
ice growth in a test tube. But while most proteins with similar functions 
have similar structures, Graether and the group he works with have found 
five different structures in antifreeze proteins.
