In the cover story, "The Mystery of Methane on Mars and Titan", could the methane in the atmosphere of Mars and Titan be caused by unusual geologic activity or life? Next, "Chromosomal Chaos and Cancer". Current wisdom on the role of genes in malignancy may not explain some of the features of cancer, but stepping back to look at the bigger picture inside cells reveals a view that just might. We'll also hear about "Preventing Blackouts". A smarter power grid that automatically responds to problems could reduce the rising number of debilitating blackouts. Finally, we'll explore "Eyes Open, Brain Shut": brain imaging techniques yield a better understanding of patients in the vegetative state.
