METHODS - New approach for  structure determination from tiny crystals

Many crystals can't be grown into crystals large enough for their atomic arrangements to be deciphered. To tackle this challenge, scientists at the U.S. DOE's Brookhaven National Laboratory and colleagues at Columbia University have developed a new approach for solving protein structure from tiny crystal. For details, please click the link.
