METHODS - Evolving data standards for cryo-EM structures

The development of cryo-EM is directly reflected by the growth of cryo-EM strructure depositions contributed worldwide to public data archived. The archiving systems and underlying data standards supporting depostioin, annotation, release, and validation of cyro-EM stuctures and the associated metadata describing cryo-EM experiments have been developed over time to support this growth. Recently,  CL Lawson, HM Berman, and W Chiu outlined the history of these systems and described the process by which data standards had been developed. For details, please click the link.

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.

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.
