In a paper published online in advance this week in Science, investigators in Switzerland report on how transcriptional bursts "generate gene-specific temporal patterns of mRNA synthesis in mammalian cells." In generating a variety of gene-trap and transgenic cell lines in which an unstable mRNA expressed a luciferase protein, the team recorded on/off transcriptional switching rates by recording bioluminescence; the researchers then used mathematical modeling to show that "burs
