New tools reveal how genes work and cells organize      (via sciencedaily.com)     Original source 

Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.

First view of centromere variation and evolution      (via sciencedaily.com)     Original source 

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown scientists how greatly centromeres differ in size and structure.
