    Without a serious review system, I can see it becoming a nest of crap that no one will be able to use.

    There is a review system--though not a formal moderated one like Slashdot. Each Wikipedia user has a Watchlist. You can add as many Wikipedia pages to it as you want, and whenever any of those pages are changed a notation will appear on your Watchlist page.

    I have a few pages on my list that are related to the work I do, or areas where I can comfortably claim I am well-versed. I keep tabs on the couple of daily changes to those articles, and check them for spelling, grammar, and correctness. Many other Wikipedians do the same. Vandalism is consequently noticed quite quickly for all but the least important articles. I imagine that the "Douche" article you mentioned is one such article that is watched fairly closely; one of the siblings to this post notes that vandalism to that article is usually undone in minutes (or--once--hours) and never a week or two.

    Wikipedia hasn't ever had the 'serious' review system you think it needs, but it hasn't become a 'nest of crap' yet, either.

    ...the moon itself is only ~0.5" across...

    Minor nitpick, and to answer another question in this thread.

    The moon is about half a degree across. Usually that's denoted by a little superscript circle, just as with temperature. Half a degree is about the size of an aspirin tablet held at arm's length.

    Alternately, that half degree can be written as 30' of arc--each degree can be subdivided into sixty minutes of arc (or arcminutes). Each minute of arc is in turn broken into sixty seconds of arc: 60" (arcseconds). The parent seems to have inadvertently shrunk the moon by a factor of 3600...oops.

    For reference, Hubble can resolve features down to 0.05"--50 milliarcseconds. Your eye can resolve point objects a little under 10' (ten arcminutes) apart.

    Also, to be fair, for locating asteroids, the galactic plane and Andromeda aren't really blind spots...they're a real pain in the neck if you're trying to do cosmology, though.

    Upregulation of heat shock proteins may in fact be good for you.

    Yes and no.

    It's definitely good for individual cells, inasmuch as it allows them to repair damaged protein and avoid programmed cell death (apoptosis).

    Whether it's good for the entire organism is an open question, and the answer is probably very much "it depends". There is evidence to suggest that higher levels of heat shock protein expression in cardiac tissue are associated with reduced injury during a heart attack. On the other hand, there is also evidence that a number of the heat shock proteins are upregulated in some cancers (roughly half of human tumours overexpress Hsp70, for instance.) High expression of high shock proteins probably allows malignant cells to survive when they shouldn't.

    As a side note, I'd take Dr. Mercola's reports with a grain of salt. He's mostly pushing his diet and cookbooks. He's also not entirely up to date on the current debate on Alzheimer's and Parkinson's. Although he correctly reports that higher levels of heat shock proteins delay protein aggregation in an animal model (c. elegans) the toxicity of the protein aggregates is still open to question.

    Some recent work suggests that the soluble protein monomer or small protein clusters are what actually do the damage, and that the aggregates that form are relatively inert. If that is the case, delaying protein aggregation through chaperone (heat shock protein) overexpression may actually increase disease severity.

    Then why dont we see people dying of cancer and other diseases in tropical or subtropical places vs temperate places?

    We do see more skin cancer in tropical and subtropical areas, and that's the only part of the body that tends to experience substantial increases in temperature. (Yes, I know it's also the only part of the body that sees sunlight--back to this point later). Your body is very good at maintaining its core temperature. It likes to be at around 37 degrees (Celsius), and exerts a good bit of effort to keep it that way. It will completely dehydrate you through sweating to fight small changes in core temperature. Remember, a temperature of 40 degrees (104 Fahrenheit) is considered a high fever, and prolonged body temperatures of 41 degrees can have a whole host of nasty effects.

    Heating individual cells to 41 or 42 degrees causes a demonstrable change in DNA supercoiling, and there is strong evidence that it disrupts DNA repair.

    What looks like 'just a few degrees' of heating can have dramatic effects on sensitive tissue. I'm not asserting that there is a relationship between localized RF heating and cancer--I am willing to suggest that even modest heating may have a potentiating effect on other stressors. (To go back to my first remark, it's obvious that UV is the direct cause of double-strand DNA breaks in skin exposed to the sun. It is possible--though by no means proven--that simultaneous exposure to heating may enhance the damage done, by inhibiting DNA repair.)

    All I want to do here is remind Slashdotters that you can accumulate DNA damage in (at least) two ways: by directly damaging it with ionizing radiation, or by inhibiting its repair.

    It's interesting that they don't offer up an explanation for the cellular damage. Last time I checked, microwaves were non-ionizing. The worst you should experience from a cell phone might be a little heat. I'm skeptical, as usual.

    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. )
