Volume 474 Issue 7350, 9 June 2011

This issue covers some of the hottest topics in stem-cell research. A News and Views article discusses the discovery that induced pluripotent stem (iPS) cells can be immunogenic. Other research articles identify an immune-privileged site in bone-marrow stem cells; a new pathway for the generation of haematopoietic stem cells; and a replacement iPS-cell inducing transcription factor for the cancer-causing c-Myc. And an article published online has identified a peptide that can stimulate progenitor cells to act as a source of new cardiomyocytes. Cover inset: D. Waters/Getty.

  • One mathematical model can account for power-law distributions in a variety of systems. Eschewing system-specific assumptions, it utilizes a shared feature of the observed distributions: they all describe the division of items into groups.

  • Infecting around 120 million people worldwide, hepatitis C virus (HCV) is more common than HIV yet it is a neglected epidemic. Diagnosis is hard, treatment is arduous, and there is no vaccine. However, for the first time in decades, new drugs are about to be launched that could substantially improve treatment and herald a new era of HCV awareness.
