DNA double-stranded breaks threaten genome stability. Here, the authors show that transcript RNA serves as a repair template in human cells and identify Polζ as a key factor in RNA-templated DSB ...

Each time a cell divides, a small section of each chromosome's protective cap—the telomere—is worn away. Most cells use an ...

Insects possess a remarkable ability to develop innate immune memory, and the mechanisms underlying this process are becoming a central topic in innate immunity research.
