METHODS - Reliable cryo-EM resolution estimation A modified Fourier shell correlation (FSC) moehodology is introduced by Pawel Penczek, which is aimed addressing two fundamental problems that mar the use of FSC: the strong influence of mask-induced artifacts on resolution estimation and the lack of assessment of FSC uncertaninties stemming from the inability to determine the asscociated number of degrees of freedom. For details, please click the link. 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.
