Cell phones don't cause brain cancer/Sea Slug is half plant, half animal

In the past 10 years or so, I’ve become more and more of a skeptic. Especially in the last 5 or so years, the American public has become increasingly susceptible to scaremongering and inflated fears about health issues, doomsday nonsense, and other junk science that has no basis in reality. The myth about cell phone radiation causing brain cancer is one example of this. The flat truth is that there had been no proven link between cell phone use and brain cancer. In fact, according to Christopher Wanjek’s column on LiveScience there has been no significant increase in brain cancer that correlates in any way with the increase of cell phone usage. We all know how much cell phone usage has risen in the last 2 decades… if they cause brain cancer, why the hell hasn’t there been a corresponding increase in the disease? Because there’s no connection. That being said, this article on NewScientist is one of many covering research into the effects of cell phone radiation on the brain, and in fact it does affect brain tissue, and there have been some hints that extremely prolonged exposure could cause some degree of tissue damage, but tissue damage is not the same thing as brain cancer. Furthermore, another recent study actually showed that cell phone radiation reversed the effects of Alzheimer’s disease in mice! (And if you look at the bottom of that article, you’ll see that the study wasn’t funded by any cell phone companies…) We might even soon be seeing cell phone radiation used as a treatment for the disease. So, the jury may still be out on whether it causes tissue damage or has therapeutic effects on memory, but with as many studies as have been done on the link between the radiation and brain cancer, it’s pretty obvious that cell phones don’t cause brain cancer. Unfortunately some companies have tried to capitalize on the scaremongering by marketing products that are supposed to “protect” you brain from the radiation. These don’t work, and several have been shut down by the FTC.

Now that I’m off my skeptic soapbox, something actually interesting:

Biologists have discovered a species of sea slug that is the first know organism to be able to produce chlorophyll. This creature actually has aspects of both plants and animals, and thus sounds like something straight out of a sci-fi movie. But it’s real. Scientists have determined that it somehow “borrowed” the plant genes that allow chlorophyll production from the algae that it consumes. Exactly how it did that in it’s evolutionary path is still a mystery. It still can’t produce the actual chloroplasts (the cells that are responsible for the conversion of sunlight into energy) without consuming algae, but it apparently can produce chlorophyll entirely on its own.

And just for kicks: How the main LOST characters would each make a peanut butter & jelly sandwich. (Via Yewknee’d)
