Questions about the nature of viruses remain quite vexing. Recent studies of the giant Mimivirus illustrate this point. Its large size and correspondingly large genome test our general ideas of viruses as small, simple entities. The existence of genes associated with translation, metabolism, DNA repair, and protein folding raises questions about the evolutionary history of viruses. Further studies of this virus, and the search for other giant viruses, may shed light on these issues.

The discovery of this genetic disorder, reported in two papers in the journal Cell, demonstrates the growing power of new tools to uncover the causes of diseases that previously stumped doctors.

"Bioethics is the study of ethical, legal, and social issues raised by advances in biology and medicine. Bioethics addresses a range of controversial topics, including privacy and fairness in the use of genetic information, integration of new technologies, such as genetic testing, into medical practice, and the design and conduct of research studies and clinical trials.  "
