Despite years of research, there is still no clear answer to the question: Do cellphones cause cancer? But two government studies, one in rats and one in mice, suggest that if there is any risk, it is small, health officials said. These two studies on the effects of the type of radiation the phones emit, conducted over 10 years and costing $25 million, are considered the most extensive to date.

The boards of CBS and Viacom have formed special committees to evaluate a potential merger, a deal that would reunite the two big pieces of the Redstone family’s media empire. Shari Redstone, vice chairman of both companies, is pushing for a merger. She, along with her 94 year-old father, Sumner Redstone, controls CBS and Viacom, with a roughly 80% controlling stake in each company through their holding company National Amusements. Shari Redstone believes both companies need greater scale to better compete against bigger rivals.
