Roughly 270 million Americans do it several times a day: talk on a cell phone. Seems harmless. But when you make and receive calls, your cell phone emits low levels of radio-frequency radiation - a fact that has fueled heated and ongoing scientific debate on the health risks of mobile-phone...
...Sept. 9, the Environmental Working Group (EWG), a public-health advocacy, released a lengthy review of past research linking long-term or frequent cell-phone use with increased rates of brain tumors, migraines and kids' behavioral problems. For their part, the phone industry and the Federal Government say cell phones are safe. The "majority of studies published have failed to show an association between exposure to radio-frequency from a cell phone and health problems," states the U.S. Food and Drug Administration on its website. But concerns are high enough that the Senate on Sept. 14 held hearings...
Despite the government's view that cell phones pose no danger, some researchers note that most of us have been using them for less than a decade. If there is indeed a cumulative risk to using a mobile phone, it's possible that users won't be aware of it until it's too late - just as it took doctors decades to connect cigarette-smoking with lung cancer. "We all wish we'd heeded the early warnings about cigarettes," says Olga Naidenko, a senior scientist at EWG and the author of the recent report on cell phones. "We think cell...
That theory is far from certain. While it's clear that humans absorb weak radiation through handsets (the EWG report noted the particular vulnerability of children, whose skulls, according to a French study, absorb twice as much cell-phone radiation as those of adults), what's not clear is whether that radiation causes harm. Scientists are waiting for the publication of a $30 million, 14,000-person international study called Interphone, which is meant to nail down the answer once and for all. But the study ended in 2006 and its authors are still squabbling over the interpretation of their...
...recognize that ISPs must find ways to ration their limited bandwidth effectively; however, this is still possible without picking the Internet’s winners and losers. Cell-phone providers charge talkative people more money, but they don’t charge based on who they’re talking to. Similarly, ISPs could charge users for the amount of bandwidth they consume, as long as they treat all Internet use equally. When ISPs start deciding which sites reach the masses and which don’t—no matter the criteria—they distort the marketplace...
