Interphone’s data on cell phones and cancer: The spin begins
A May 16 press release by the cell phone industry reports that “The International Journal of Epidemiology today published a combined data analysis from a multi national population-based case-control study of glioma and meningioma, the most common types of brain tumour.” In fact, the journal hasn’t. Yet. But the industry group was anxious to put its spin on the paper’s findings after a handful of UK newspapers reported on this study – well in advance of the scheduled lifting of a news embargo on its data.

Vitamin D: Obese and ‘uniform’ risks
Although Vitamin D insufficiency has reached what might be considered epidemic proportions, it’s failed to move onto the radar screens of most physicians, much less consumers. A host of new studies now link excess weight with a deficiency in this, the sunshine vitamin. But that wouldn’t explain why female soldiers become increasing D-ficient during basic combat training. For them, an Army study suggests, the problem may trace to what they wear.
