  1. Nope, bacteria degrade cholesterol, they do not use it as eukaryotic cells do. Gram-negatives have good enough membrane integrity, the outer cell membrane contributes much to it. You should check bacteria out that live in close association with said eukaryotes. Wild guess: Nocardia.
  2. Well, the correlations are weak to begin with and would warrant more statistical analyzes. Chances are that they are not significant to begin with.
  3. Polar or non-polar are not dichotomous variables. Take a look at the structure, especially the aromatic ring.

    bascule, for phones it is a different matter. But my point was that for productivity purposes (and the iPad is simply too big to be directly compared to a phone) I cannot see it being more efficient. Imagine correcting papers. I can sit in a plane, draw circles around stuff that I like to have changed make a few sketches about how the graphs should look like and hope that someone can read me handwriting (or let the software try to figure it out). That does not work with touchscreens. If I was only texting, well yeah then I wouldn't need it. The only disadvantage a convertible has (again, it comes with a touchscreen) is that it is heavier than an iPad. But then the question is what the iPad may be for. In the current iteration it is not a good working platform, too big for a mobile replacement. It may be ok for a reader, but bloody expensive and harder on the eyes than e-ink.

    Bascule, the convertible I use can use stylus as well as your finger. I am not too big of a fan of smearing my fingers over the screen though and for making small notes or sketches the stlyus is much more useful to me. It is simply faster to ink in a document than call up a touch keyboard and type stuff in it.

    I use a tablet notebook for that. It is a bit more expensive but it also serves as a full fledged computer. The only advantage I could see is that it is a bit lighter, but for the price it is not really an incentive for me to get one.
  7. As usual the obvious disclaimer that medical tips on fora have always be taken with a grain of salt. Generally speaking, however you should make a blood test to see whether you have a serious infection to begin with, before trying to target specific bacteria.
  8. As all viruses it hijacks the hosts cellular mechanisms. As for the rest, you should read up on retroviruses and how they infect cells.
  9. Ugh let's not mix terms here, please. Genetic and evolutionary algorithms are special programming strategies to solve problems. They are inspired by evolutionary theories, of course, but do not have the explicit goal of mimicking biological behavior.
  10. Yes. More precisely, infected cells do that.
  11. This enzyme is not secreted by an organ per se, but is encoded in the HIV genome.
  12. Ah, photometric assay in liquid. I think the one from Sigma is an assay often done in courses. Regarding free papers, if your access is limited you may want to search open access journals first (e.g. BMC, PloS, Biomed central). Just a thought.
  13. There are dozens of different catalase assays. You need to put it into a little context. Otherwise take a look at some reviews. One of the oldest is probably The assay of catalases and peroxidases. MAEHLY AC, CHANCE B. Methods Biochem Anal. 1954;1:357-424.
  14. Except of course that for one case there is overwhelming evidence, whereas for the others baseless opinions.
  15. Hm I really thought that he was using real values not that mockery of a poor excuse of one. In that case the yeas will indeed not die (as I assumed initially). Chances are that there is still too much oxygen. Given what I see regularly on the streets here, I am not sure that it makes any difference on which side they drive...
  16. Uhm you got a couple of things wrong. Yeast does not ferment methanol from sugar, regardless of distillation. Based on your description I will assume that he is in for some bad tasting sugar water.
  17. I generally do not recommend web sites in order to get a general understanding of biology. The reason is that due their very nature web sites often deal with individual topics and really more suited to inform on facts rather than concepts. Usually text books do a better job in that regard.

  18. Well I think the OP was aiming the most obvious answer. Eating the orange, setting fire to things and giggle maniacally. That is what every sane person would do, of course.
  19. There are certain metrics that one could use, including facial symmetry. Nonetheless the OP is too vague and anecdotal in nature. Thus I elaborate on Sh3erlock's answer and propose that Zeus decided to have a go as mailman this time.
  20. One could stick the orange into ones mouth and try to blow out a lighted lighter. It is kind of hard, or so I heard.
  21. Why would you think that no anesthesia is used on burn patients? I believe that wound patients are challenging for the anesthesiologist due to the unstable nature of the patient. In some rare cases it may not be advisable, but I believe that it is pretty much common practice.
  22. Mild tapeworm infections do not result in weight loss either. If it is bad enough for you to lose weight, worse things are going to happen soon. Also, while co-evolution often favours the survival of the host in the long run, it is not necessarily so. For quite some parasites the death of the host is necessary for them to spread.
