  1. There is more than that: DNA-RNA-Proteins (composition and synthesis), the genetic code, remarkable conservation in central metabolism, especially within eukaryotes.
  2. Congrats and all the best wishes for the lil one!
  3. Depends on the company and what they sell. But especially for generic labware I suppose it is not out of the question. You should have decent people's skills, though. Typically the companies will have their requirements posted. But be aware that they are not trying to buy someone with a degree, but rather who can represent the company and sell their products.
  4. Not within a second. An average transcript requires about 10s or more, a protein significantly longer. However tens of seconds to minutes would be correct.
  5. That is true for almost all branches of biology. There is no clear line, however, physicist tend to work on physical phenomena and just happen to use biological substrates as experimental subject, whereas biologists are more interested in functions and physiology in a biological context and just happen to apply (sometimes badly) tools from other disciplines. One distinguishing criterion (for students) tend to be whether you are able to generalize the underlying math (typical for more physics inclined people) or whether you are able to maintain a proper culture and are able to explain physiological effects (which often amounts to "why the $%%$#%# does the @#$@$@%@@ did that again?"). The hallmark for a truly interdisciplinary researcher is if neither side thinks you belong to them.
  6. Which data set do you have? Looking at the wiki page it appears to me that at 2000 it was still rising but starting to plateau and the first drop (which does not seem overly dramatic in slope) sometime between 2010-12. The data set was Incarceration per 100k 1925-2012, btw. That drop is at least partially explained here. Edit: crossposted with Zapatos.
  7. Using OP's criteria, any natural scientist is a physicist. We just use different levels of abstraction and simplifications. Which makes it a rather pointless claim, no?
  8. There are a lot of possibilities for a lot of things. In the absence of data it remains speculation.
  9. Well, there is a lot of information on it, is there anything particular you are interested in? Essentially it is a protein that belongs to the family of cytokines that are typically involved in cell signaling. Omentin-1 is, to my knowledge, secreted by adipose (fat) tissue. edit: crossposted.
  10. One the more comprehensive reports is this one: Valberg et al. ENVIRONMENTAL HEALTH PERSPECTIVES Volume: 115 Issue: 3 Pages: 416-424 Abstract:
  11. Oh yeah, to them it obviously will appear rational. Typically they act they way as they believe it is the best for their child, which makes it even sadder.
  12. Problem is that parents who keep their children unvaccinated have likely done so for irrational reasons. I am not sure whether they would open to discuss their ordeal in a helpful manner.
  13. One thing to consider, especially if our child is not vaccinated and you are surrounded by non-vaccinated children (if you happen to be surrounded by like-minded parent) then you are putting all of the infants at an unreasonable risk. To put it bluntly, you risk health and well-being of your child for some unfounded beliefs. The risks of long-term effects (including death) are much higher. Take DTaP : 1 in a million have sever effects (which may be unrelated to the immunization). If your child contracts diphtheria (which is unlikely now as most are immunized and as a result incidents have dropped close to regional extinction , but if people stop, it will come back) it has a chance of ~20% of dying. 1:5 vs 1:1000,000 (if that). Take your bets.
  14. Not necessarily. There are models which help in explaining altruistic behavior in population (kin selection for example). One has to keep in mind the difference between proximate and ultimate explanation. In this case kin selection would be an ultimate explanation (i.e. indirectly propagation of one's genes), whereas proximately there are mechanisms in place that causes organisms to act altruistically. Depending on how they function they be more or less specifically directed. Often times, one would imagine that learned behavior and imprinting are important (e.g. interaction with ones offspring or relatives) and they may be misdirected to the "wrong" species, depending on how selective theses behaviors are. I.e. the thing is complex, but there are specific hypotheses that could be tested.
  15. Sales depends on what the company does (does it fabricate and sale or is it a vendor?). But in the broadest sense the job in sales (or account manager) is to keep your customers happy so that they come back for more. Typically you would identify how your products would fit the needs of a given lab or company, and present or demo it to them in a tailored fashion. A vendor would e.g. identify products needed by the lab offer discounts etc. Depending on level specialization the sales person often also acts as liaison between the buyer and the technical support team/application specialists. You do not actually actively sell things, but rather your job is to integrate into the buyer's need at some level (can be singular expensive item, like a mass spec, or consumables) and try to meet them. Marketable things? Understanding the products and who/how/when they are used. Know the target audience and be able to communicate with them effectively (especially scientists are not very amenable to business-speak). I have yet to meet a sales person with a business degree of sorts. Most that I interact with or know privately have MSc or PhD degrees in relevant areas.
  16. People who think that they are competent at something (but aren't).
  17. If you have a 5' overhang, how can you ligate without a 3'? But for multiple products there is always self-ligation, concatermerization, multiple PCR products (very common) etc.
  18. Actually it is not. The problem is that these observations are individual events and can be interpreted any way. In other words, the data is "wooly" but not the concept. In population studies an altruic behyavior is essentially someething that decreases the fitness of the actor, while increasing that of the recipient. The problem is that it is not trivial to determine when such fitness increases or decreases actually occur.
  19. According to popular opinion/school history, yes. Good think that historians tend to look at things a bit deeper (though it may take a while until things get pieced together). In this particular situation even a rather insane government would have a bit of hard time explaining how killing Norwegian kids ultimately preserves Norway. Unless it will be come a Battle-Royal-style dystopian future. Then yes.
  20. Do you mean actual biofilm (for which various visualization techniques including stains exist), or just adherence? While adherence is the first step, it is not necessarily the same. Assuming the goal is the measurement of simply adherent cells, it depends on how precise you want to be. As a basic approach one applies a defined amount and identical amount of shear forces to each sample in order to remove bacteria who have surface interactions forces below that given amount. Depending on what you have at hand, centrifugation, use of defined water jets/flows, micromanipulators and AFM are options. The point being that there is no absolute distinction between adherent and planctonic cells. There will always be some level of force, depending on substrate and cellular surface properties (such as charge, morphology etc.). Typically, for each question the design has to be altered. E.g. looking at adherence under a no-flow system would be treated differently (as cells have a long time to settle) than during some kind of active shear forces acting on the cells.
  21. What defines a non-failed state? What level of stability and for how long? The whole of Europe was in a dismal state ~70 years ago. Is there a fundamental time limit to these things?
  22. I know that they are in Mecklenburg-Vorpommern and Sachsen and was but I was not aware of things on the federal level. Luckily a quick google showed that they are still far away from the Bundestag. It is of note that the party is actually actively agitating against the state and was close to getting banned (before the huge mess made it impossible). Plus this party is associated with a terror group. The argument for prostitution is not a matter of moving things underground (otherwise, murder should be be made legal, as people would just do it in the hidden, right?). It is more a matter of whether legislation is more useful or harmful to the people involved.
  23. I sure hope that NPD has not gotten any seats in the federal parliament!
  24. That is a crucial point (which I conveniently and to my shame overlooked). But on the other aspects, yes development of complex traits are also regulated by quantitative balances of the various players (including transcriptome, proteome and metabolome). The balance of many of these constituents is what results in certain cellular and tissue phenotypes and not only the types of proteins present (though that is an important point, too, of course).
