Summary

Increasingly reliable mathematical models can now predict parts of the three-dimensional structure of proteins much faster than they can be determined by x-ray crystallography or nuclear magnetic resonance. In the latest computer-assisted coup, mathematicians and biologists have developed a program that predicts in milliseconds whether a protein folds into a structure called a b helix. To their surprise, they found that a protein with a b helix is like a child with a can of spray paint: It's almost surely up to no good.
