In case it wasn't already obvious that kids under the age of eight should be using cellphones strictly for emergencies, here's another reason: Toronto's public health department says so. In what might be a first in all of Canada, the agency is officially laying down recommendations that tykes be restricted to emergency calls and teens talk on their phones for no more than ten minutes at a time (good luck with that one) due to growing evidence that prolonged use could lead to brain tumors and other health-related unpleasantness later in life. Moving up the governmental food chain, Health Canada still officially recommends no restrictions, so the endless confusion over cellphone safety continues as usual.

You've heard just how dangerous holding that cellphone upside your noggin is, but this time, the research is really for real. Reportedly, an award-winning cancer expert (Dr. Vini Khurana) has concluded that mobile phones -- in the long run -- could end up killing far more Earthlings than smoking or asbestos ever could. As we've heard countless times before, this fellow is warning that heavy mobile users could end up with brain tumors that threaten their livelihood, and feels that a direct link between handset use and certain tumors will be "definitively proven" in the next decade. Additionally, he suggests that individuals avoid using the cancer generators whenever possible, and that governments and the mobile industry at large take "immediate steps" to reduce radiation exposure. You won't be laughing if he's right.

Lest the danger (or non-danger) of cellphone use stray too far from your mind, here's a trio of recent studies to get the juices flowing again. First, the best news: an Australian researcher has come up with a five-point ranking system to lay out the likelihood of getting cancer from partaking in various substances and activities, and if that system has any basis in reality, cellphones are "unlikely" to cause cancer -- so take it for what you will. The second study, thrown down by the Cleveland Clinic, showed a significant decrease in sperm "quality" (as determined by a number of stats) as average daily cellphone usage increased; not necessarily a short-term problem for the users themselves, but a finding their future children (or lack thereof) might take issue with. The third study brings more bad news, showing that human skin exposed to cellphone radiation altered the cells' protein expression, a potential (though by no means definitive) precursor to cancer. As always, your mileage -- and your body's mileage -- may vary.

Researchers across the pond at the UK Mobile Telecommunications and Health Research Programme (MTHRP) are without a conclusive answer on the short term effects on the brain from mobile phones. After a six year study on the effects of mobile phones on brain and cell functions, researchers found what's to be described as a hint of a cancer risk when exposed. Does anyone else feel a little nervous with non-scientific words being used to describe negative consequences of something most of us do on a daily basis? Leave a comment if you can break the medical jargon!

So apparently, virtually all existing official limits for radiation emitted by mobiles (FCC, we're looking at you) are based on the assumption that the dangerous effects of that radiation are caused by heating of the brain. Pretty big assumption, eh? A new study by Israel's Weizmann Institute of Science suggest that some "non-thermal" forces are at play, though, noting that chemicals involved in brain cell division were affected in tests on rats after just 10 minutes of exposure to cellphone radiation. Improper cell division goes hand in hand with cancer, so the finding is a rather alarming one. Of course, you know the drill: for every study that suggests phones are dangerous, we can certainly dredge up one that says they aren't -- just be forewarned that a cool brain isn't necessarily a healthy one.

Just when we thought we had this whole cellphones do / don't cause cancer bit was behind us, here comes another study to say that they in fact do. The study, which was put together by Finland's Radiation and Nuclear Safety Authority, suggests that people who used cellphones longer than 10 years were 40 percent more likely to develop gliomas (a nervous system tumor) on the side of the head where the cellphone's radiation would enter the head. While we are aware of several studies that go either way on the matter, Microwave News' editor Louis Slesin thinks it is "compelling evidence" because, "We now have two tumor types found among people who use mobiles for more than 10 years shown by two different research groups." Of course, a rebuttal from the Mobile Operators Association said otherwise: "The findings related to tumor location are difficult to interpret." It's hard to really form an opinion considering the amount of data that consistently contradicts itself, but you can decide for yourself when the findings are published in International Journal of Cancer later this year. For now, we will have faith in our mobiles and pray that later on down the line we're not on the wrong end of the impending "I told you so."

While we aren't claiming any prophetic abilities, it wasn't exactly hard to assume that just over a month after a thorough Danish study cleared cellphones of any wrongdoings associated with cancers and tumors, we've got a so-called expert lobbying for £3 million ($5.92 million) in funding to prove otherwise. Professor Lawrie Challis, who is in the final stages of negotiation with the Department of Health and the mobile phone industry for the aforementioned dough, seems to think that there's still a "hint of something" that could develop in long-term, heavy mobile users "after 10 years of use." Granted, he has literally books of research disproving this "hint," but as he references cases like asbestos and Hiroshima, he suggests that a study must be done now in order to prevent anything even more dramatic from cropping up in a decade or so. Reportedly, "over 200,000 volunteers, including long-term users, are to be monitored for at least five years to plot mobile phone use against any serious diseases they develop, including cancer, Parkinson's, and Alzheimer's diseases." So it seems the circus begins again, and in the meantime, let's just all cross our re-paranoid fingers in hopes that nothing goes awry (and that a counter-test shoots it down) while this study unfolds.

We've seen so many chapters of the "dangerous / not dangerous" chronicles with regard to cellphone radiation that we've lost count, but thanks to a Danish study recently carried out on 420,000 avid mobile users, we can finally put those worries to rest (we hope). While it's no secret that mobile phone antennas emit "electromagnetic fields that can penetrate the human brain," we've been yearning for a study such as this to quiet the tin-foil advocates (and ensure our own safety). Researchers from the Danish Institute of Cancer Epidemiology in Copenhagen looked at data on people who had been using mobile phones "from as far back as 1982" in order to draw their conclusions, and after all was said and done, they found "no evidence to suggest users had a higher risk of tumors in the brain, eye, or salivary gland, or developing leukemia." Thankfully, a similar study published earlier this year by the Institute of Cancer Research also concluded that mobile phone use "was not associated with a greater risk of brain cancer." So, there you have it folks, you can safely yap away without fear of mutating into some form of diseased being -- until the next study "proves" otherwise, of course.
