UVB, and part of UVC will cause Ultraviolet Keratitis ("welder's eye" or "snow blindness"), and UVC is the worst for causing skin cancer (UVB causes cancer too, but UVC is worse).

      Skepticism is certainly warranted, but I haven't had time to look at the published paper. (Lay articles are always skimpy on details and often get them wrong anyway....)

      Even though heat won't directly cause DNA breaks, it might muck up DNA repair machinery so that breaks formed by other processes aren't repaired. Thermal radiosensitization, for instance, is a phenomenon we've known about for at least thirty years. Mild, otherwise non-fatal heating can dramatically increase the sensitivity of cells to other, ionizing radiation. This is sometimes a useful effect (see below) but might increase cancer risk in otherwise healthy individuals.

      Moderate heating (to four or five degrees above normal body temperature) will dramatically but reversibly alter the supercoiling of DNA as well as alter the phosphorylation of some of the core histones. It will also trigger a temporary upregulation of the heat shock proteins, which directly interfere with apoptosis. Hyperthermia actually has a whole pile of effects that are not well understood. This is not to say that I'm going to start carrying my mobile phone in a lead pouch, but I think it will be interesting to see where this research leads.

      Interestingly, there are a number of clinical trials in Europe right now that take advantage of thermal radiosensitization by combining local heating with radiotherapy for cancer treatment. (See for example the Phase III Dutch Deep Hyperthermia Trial, link. )

  41. Why is talking on a cellphone considered rude? by pauljlucas · · Score: 2, Insightful
    No, seriously: why? Why is a person sitting on a train next to you who is talking on a cellphone rude and/or annoying? Why is it different than a person talking to another person face-to-face?

    If the person talking on a cellphone is talking too loudly, then it's the fact that the person is talking too loudly that is annoying. The fact that the person just so happens to be talking on a cellphone while doing it is irrelevant.

    I've occasionally been around people who simply talk too loudly to other people.

      While in the movie theatre? Yes.
      Again, the phone is irrelevant. It's equally rude/annoying if a person is talking to another person sitting in the theater (in which there should be no talking by any means).
      While in a shared office? Yes.
      How is talking on a cellphone more rude/annoying than talking using a landline in a shared office? I've been in plenty of shared office spaces and had people talking way too loudly on their landline.
      While driving a car? Yes.
      Assuming you're not in that car, I fail to see how this is rude or annoying since you can't hear the conversation. It's more dangerous, perhaps, but not more rude/annoying.

      I've always found that killing someone, through any means, to be quire rude.

  42. Rude by mariox19 · · Score: 2, Interesting

    People seem to talk louder on cell phones than when talking to one another. Also, I remember reading an article that said it is easier for us to tune out a conversation when we hear both sides of it than when we are hearing only one side. Apparently, a natural reaction is to try to piece together the other side of the conversation.

    What bothers me most though is the damn Nextels. These people having their walkie-talkie conversations on speaker phone, punctuating ever sentence with a chirp piss me off. There are times when I've wished they would literally drop dead.

  43. Wavelengths are completely different from optical by elgatozorbas · · Score: 2, Informative

    The wavelength of cell phones frequencies are of the order of magnitude of 10-30 cm in vacuum. In any other material, they are lower (by reasonable factors, depending on the material, e.g. 3). Now I am not saying there cannot possibly be any bad effect, but I would be highly surprised if these waves brought DNA (very small, microns or so?) into resonance.

    Optical frequencies are orders of magnitude away from cell phone frequencies, UV even more.

  44. Re: beneficial Mutations by AlphaWolf_HK · · Score: 2, Interesting
    Hmm...I thought high energy waves are dangerous because they collide with the chromatin (since it is the thickest material in the cell and therefore the most likely for them to collide with) either severing it completely by fragmenting a huge portion of it (in which case the cell will either die or be destroyed by the immune system, it has almost no chance of survival here thus no mutation occurs) or damaging a small portion which if the proper enzymes are available, will re-attach on the 5 prime end, but the re-attachment doesn't leave the DNA in its exact previous state, thus an effective mutation can occur (be it good or bad.)

    But then the previous case could also be good as well though. The most widely held theory about the difference between males and females is that a huge segment of chromatim simply broke off and the resulting organism was able to thrive. I could see why 99.9999% of them would have negative results (since you have several million energy waves hitting the chromatim at a time,) as opposed to the 90% of natural mutations. But I would guess that there should still exist the possibility that a mutation triggered by high energy waves could provide some benefit (although I would strongly advise against exposing yourself to high energy radiation if you wanted to become superman.)

    If the person talking on a cellphone is talking too loudly, then it's the fact that the person is talking too loudly that is annoying. The fact that the person just so happens to be talking on a cellphone while doing it is irrelevant.

    Not entirely. Wired phones feedback part of the signal from the microphone to the earpiece. This audio feedback is a side-effect of simple analog phone design, but it also serves to help you know the line is live, and help you regulate your volume because you can hear yourself well, and so you assume the other person can hear you.

    Cellphones don't provide this feedback. Thus one of the clues you get on a wireline phone is missing. Some people seem to need this clue to help them regulate their volume and some people don't.

    Another way that cellphones differ is in audio quality. In general, if you can't hear someone well, you increase the volume at which you speak - this is something we learn when we're very young. Poor cellphone codecs and poor signal strength contribute to the feeling that the other person can't hear you very well, so subconciously you speak louder. Again, different people are affected by this differently, but the effect is pretty common.

    So cellphones really are different from wired phones, although not everyone is affected by those differences in the same way.
