Peer-to-peer reciprocity is important, and having the ability to practice targeted reciprocity in our experiment increases contributions to the public good by 14%. Subjects reward group members...

Here, we report that tight protein-DNA complexes induce ectopic recruitment of the SIR complex, promoting gene silencing and changes in subnuclear localization when cis-acting elements are nearby. Importantly, lack of the replica...
