The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

The Protein Structure Initiative (PSI), a national program aimed at determining the three-dimensional shapes of a wide range of proteins, has now determined more than 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the...

Bird Brains Show How Trial and Error May Contribute to Learning
