Salon has done a service by gathering the responses of 11 scientists and science journalists to the recent news from the World Health Organization that mobile phone usage poses a "possible" cancer risk. We all pretty much say that we're not very worried, and a number of folks point out that using your cell phone while driving is a far bigger risk than any cancer risk, for obvious reasons. My contribution was not very verbose, but I think it captures what we should take away from the science in many ways:
I use the classic white headphones with my iPhone but much more out of convenience than out of fear. This report--calling mobile phone use a "possible" carcinogen--won't change that.
Other responses come from Natalie Angier, PZ Myers, Antonio Damasio, Ed Yong, and others. Check them out here.
