  1. Not all of the genes have meaningful name. The first to assign a function generally can give them any name they want (though nowadays people cross-reference it to the ORF name, if a genome sequence is available). Other than that you should just check the regular databases as swissprot (for proteins) or Genbank, in which the full name is sometimes deposited. Blimp1 stands for B lymphocyte-induced maturation protein, btw. and is also called PRDM1 (Positive regulatory domain) as it binds to the PRDI (positive regulatory domain I element) of its target gene.

    Netbooks

    AFAIK Atom is soldered onto the motherboard. However RAM is the same. Just check the specs.
  3. Eh, wait somehow did read the question wrong.The suggested order would not work. For instance, do you think that the nucleophilic attack would work as the first reaction? I.e. does the hydroxyl group has a reasonable chance to form a covalent bond with the C of the substrate?
  4. iNow, I suppose the information of why is within the statement: What is lacking, however is the analysis accompanying this. I.e. what is the impact of the deleterious effects and at least an estimate of the how much the activities of the upper-bracket business would be diminished. The important question is IMO not whether tax expiration has an impact in economy or not, but rather how much the impact would be and how it compares to the impact if this tax revenue would be invested by the government in certain programmes (or to reduce deficit or whatever).
  5. It is a bit of both. The poultry can be infected to begin with, and after intestinal colonization it can spread systemically. Usually those that are that sick do not enter the human food chain (hopefully). The rest can be the result of handling during the slaughtering and subsequent processing. The most significant amount is often the result of subsequent growth after contamination/infection, though.
  6. One problem could be that the licensing scheme of Apple may inhibit the development of open source software that are often used for a variety of stuff. Also, currently most apps are at a low price (AFAIK) and people could be reluctant to buy an app for a few hundred or thousand bucks, which the commercial software often demands.There are other smartphones out there that may be more useful for developers as e.g. the Nokia N900. Though from a price standpoint it could be more worthwhile to get a netbook, which at least does not require new software and still is somewhat portable.

    Muscles Question

    Muscles are attached to bone (via tendons) and by contracting they pull at them.
  8. I think his tangent was a media-biased view on American society, pretty much unrelated to political alignment. It is based on the assumption that around 20% or so of the Americans have silly views (death panels, secret muslim extremist terrorist president, CIA did 9-11, etc.) and that those dominate the media (one way or another). The "normal" majority does not make the media however and thus the view on American society is oddly distorted which in turn further heats up the discussion and leads to more distortion, polarization, etc. Fair point, and I do not have the time to check whether there is data out there. However, generally the government takes the blame for everything going wrong under their watch, which gives the opposition more fuel. Also the opposition has an interest to paint the current picture as black as possible in order to win the next election. What current political climate are you referring to?

    Muscles Question

    Also, if you are interested in understanding how muscles contract, ignore pioneer's post.
  10. Often one does not need a lot of structure or mechanisms to integrate information, if it is already encoded withing the signal itself, if that makes any sense. For instance,if the brain also gets eye movement information (which it does) it can easily pinpoint the visual field relative to the body position, without the need of extensive reconstruction. In fact even in humans the continuous perception is largely an illusion. Split brain experiments are an example, for instance. The individuals with their pons damaged still perceive things as continuous, though in truth they have two non-interacting visual fields.
  11. As a rule of thumb the party (or parties) not in power tend to cry the loudest. Somewhat off-topic but the though crossed my mind that it could be amusing to collect the most ludicrous claims of either side (I am thinking "death panel" level of silliness) and to cross-compare the amount of them to their temporal proximity to elections. Edit: I meant claims from actual politicians, not pundits.

    Muscles Question

    No, they cannot. The molecular mechanisms of muscle movement exert force exclusively by contraction (if you are interested in details you should look up actin-myosin filaments).
  13. Interesting thought experiment. Would you rather be ruled by able, benevolent dictators, or greedy, self-serving, imbecilic elected officials. Of course the preference for the latter is based on the fear that the premise of the former (able and beneficial) might change. Of course one could try to appoint a dictator for a time for kicks.
  14. Well, it is able to react to anything in either part of its vision. I am only speculating here (thought there should be info around somewhere) but chances are that eye positioning will be part of the information sent to the brain to interpret the visual cues. The overall impression it has is likely similar to us humans, lacking sensory info is glossed over in the brain. Regarding is a bit more complicated compared to just seeing things. The interpretation of the written words usually requires quite a bit of focus. Unless the hypothetical chameleon would a have specialized area each able to read independently the ability to see incoherent views will not allow it to read (but theoretically it could switch from reading with one eye to reading with the other in fast succession).
  15. This is very much an oversimplification of the issue and I have to add that biologists would do very well by taking lessons from other methodologies.
  16. For world history I enjoyed " After Tamerlane: The Global History of Empire Since 1405" from John Darwin. Here is a review.
  17. Data is inconclusive (as noted above). Moreover the methodology may not lead to a result that could support (or falsify) the assumption. Moderacy does not necessarily mean that he would criticize both parties equally. It rather suggests that he would pound on those making outrageous claims. Considering that democrats are in the government it is more likely that attacks from the right are more likely to amount to silliness. Though during the elections idiocy on the democrat side is to surely to surge.
  18. My thesis is hosted by the university. And I think there was an effort in the UK to digitize phd theses. At least that is what I heard a while ago. Chances are that people are more interested in the published parts of it, though.
  19. Indeed. From a purely practical standpoint it has the advantage that the tuition fees are much lower.
  20. At least according to This. Though I do not understand why they split neurobiology from biology proper.
  21. Regarding infant mortality rate, the US adheres to the WHO definition of live birth and I think Australia also does the same. Many countries adhere to the WHO definition (and usually in comparative analyzes the WHO definition is used). Known exception include countries of the former Soviet block. This confusion may be the result from looking at different years. Germany stated using the WHO definition only after 1991. Switzerland and Italy used to have a different definition, but I am not sure how it is currently. The point about the special definition of the US has been overstated a fair bit. Link To clear this up a bit one could compile a list of countries adhering to the WHO definition and just compare those (though I think the WHO statistics is based on that, anyway). There is an interesting paper where they only compare a few cities (Tokyo, New York, Paris and London) to monitor differences on the microscale: Link
  22. A detailed view on science reporting Guardian
  23. In addition you would need enormous amounts to cool something the size of a house significantly. Cooling it down to liquid N2 temps is of course impossible but even getting close to it would require literally flooding the house in it. Most likely you could suffocate the insects, however many can survive lack of oxygen for quite a while.
  24. Well, somatic evolution is more of ecological interest seeing the body as a population of cells. However they are really only applicable in terms of tumorigenesis and immune development. This is a very specialized application of evolutionary theories and is not clearly in line what is stated in the OP.
  25. Eh, the context is totally wrong. Evolution is about changes in allele frequency. This cannot happen on an individual level (esp. considering that all cells share the same genome).
