Ars Technica writes: "The use of cell phones is growing rapidly, and they join an increasing number of electronic devices that emit radio frequency (RF) radiation. Although various scares have linked RF emitters to cancer and other health concerns, the scientific data don't support any definitive conclusions. The data from short-term studies is at worst inconclusive, while longer-term studies aren't available and are likely to catch a snapshot of both usage patterns and RF transmission technology that will be irrelevant by the time they're complete. Meanwhile, biologists have yet to describe a mechanism by which RF radiation can do anything more than warm tissues.

Now, a new study wades into this controversial area, focusing on behavioral changes linked to cell phone use, and its conclusions carefully consider all the reasons why factors other than RF radiation are likely to be behind the link."
