Diffley, deputy director of the London Research Institute of Cancer Research UK, and members of his Chromosome Replication Lab, on experiments that were designed to test mathematical modeling to predict a previously unknown biological mechanism of regulation. The results, published online in the journal <i>Nature Molecular Systems Biology</i> on Oct. 13, 2009, verify the computationally predicted mechanism.
