How do they know that a snapshot they took back in 1996 was still true for the population in 2000, 2005 and 2008?

    You will be wasting your time, unless you also know how to make it resistant to current vaccines and neuraminidase inhibitors:

    To assess whether current control measures may be effective against the H5 transmissible reassortant mutant virus, we examined the reactivity of sera from individuals vaccinated with an H5N1 prototype vaccine38 against a virus possessing the N158D/N224K/Q226L/T318I mutations in HA. We found that pooled human sera from individuals immunized with this vaccine reacted with the virus possessing the mutant H5 HA (N158D/N224K/Q226L/T318I) at a higher titre than with a wild-type H5 HA virus (VN1203/PR8; Supplementary Table 6), indicating that current H5N1 vaccines would be efficacious against the H5 transmissible reassortant mutant virus. In addition, the H5 transmissible reassortant mutant virus (HA(N158D/N224K/Q226L/T318I)/CA04) was highly susceptible to a licensed NA inhibitor, oseltamivir (Supplementary Table 7). These experiments show that appropriate control measures would be available to combat the transmissible virus described in this study.

  9. Re:Grants-whores and publicists in academia?!?!? on Majority of Landmark Cancer Studies Cannot Be Replicated · · Score: 1

    It is not that this cannot happen in science - more that the bad science will always eventually be revealed eventually. TFA only serves to reinforce this idea. Though it is a tragedy that these particular problem studies were so lacking in scientific rigor, it is reassuring that the peer review system ultimately brought them to light, even if it took some time to do so.

    Unfortunately the peer review system did not bring them to light. If anything the peer review system of grants and publications reinforced the crappy science (look at table 1 in the article, the reproducible articles were actually referenced less). What brought it to light was that somebody (Amgen) spent tons of money and effort to reproduce the studies and went ahead to announce the aggregate negative data. I don't see the specific studies being quoted. From my contacts in the industry I hear this story all the time. I personally moved to the cancer research field 2 years ago and I spent most of my time since then trying to navigate between artifacts due to poorly controlled experiments and pure lies.

    Having said that, I don't know of a good alternative to the peer review system. I would rather see peer review being enhanced with more open pre-publication access (like Arxiv) where more people can comment on data before it gets published.

    Another approach is to get NIH to rethink the amount of 'grant overhead' - money that go to the institution instead of the researchers to cover things like utility bills and facilities maintenance. Right now it stands at 50% of the grant award ($250K R01 grant would pay the institution $125K), which is more than twice than the overhead non-for profit organizations allow on their grants (10-20%). That's a lot of money and it creates a 'business' where institutions will pressure researchers to compete for NIH funding at any cost so they can get more overhead. In some cases universities even borrow money to expand research space and recruit reserachers, again with the sole goal of getting more 'overhead'. This was sustainable while the NIH budget was expanding, but in the recent years the budget hasn't grown much, which has made the competition even more fierce. The incentive to publish anything so you can get grants has become enormous, because now the NIH grant money not only affect your ability to do research but also your job security entirely depends on it, as the university will kick you out very quickly if you don't bring in the NIH grants. In addition the large overhead eats money that can be spent directly on research thus allowing more thorough studies.

    There is also the issue with the NIH mandate which is to cure disease. This is not bad in itself, unless you realize that NIH is the biggest game in town as far as biology research goes ($30B vs $7B for NSF, and NSF funds all kinds of research). So we throw this pile of money with the major goal of curing diseases (aka translation research), creating a disproportional incentive to bring 'practical' discoveries like drugs, therapies and diagnostic tests instead of understanding biological phenomena. The sad part is that the translational research derives from basic research and if you don't have a solid base all you can come up with is junk (do I need to explain the 'garbage in, garbage out' concept?).

  13. Re:There's Your Problem Right There on Tennessee Passes Bill That Allows "Teaching the Controversy" of Evolution · · Score: 1

    Ummm, the latter is exactly what evolution is. Mutations occur, the resulting changes are either propogated because they provide some objective benefit, removed from the system because they are detrimental, or become part of the background noise of genetic variation if they are neither harmful nor beneficial.

    Ummm, I think the parent has it better than you. Evolution is about creating 'different' rather than 'objectively improved' organisms. A mutation can be fixed in the population not only trough natural selection, but also through genetic drift. So genetic variations that are neither harmful nor beneficial (aka neutral) can become the predominant genotype and not just 'noise'. In fact genetic drift will fix even 'objectively' disadvantageous mutations as long as they are not under strong negative selection (high cholesterol at later stages of life anyone?). Beside the separation of 'good' and 'bad' mutations is not clear cut, because it depends on the environment in which the organism lives. And as we know environments have the pesky tendency to change. Are mutations that give you sickle cell anemia good or bad? The answer is: depends on where you live. If you live in a place with endemic malaria, having a mutated copy of the beta-globin gene may come handy.

    This is yet another case of how stupid PR does damage to otherwise good science. The original paper (not the PR release) describes a statistical model. The model tells you how likely it is for a mutation to affect splicing. According to ROC curve on figure 4 it isn't nearly as selective or sensitive as you need it to be for any clinical application. It is however a great research tool. The PR article makes another false assumption, by stating that mutations affecting the splicing of an exon invariably cause 'trouble'.

    Sure, if you already know what you're sick with then a specific test for that condition will, in certain cases, be cheaper. But the point is you don't know.

    You walk into the doctor's office with symptoms that could be cold, flu, the onset of bacterial pneumonia, etc. - and, in a few years, high throughput sequencing will tell you exactly which antibiotics/anitvirals (if any) to take.

    Your car analogy is not very appropriate. To begin with I have been riding the automobile in question for couple of years, and its predecessors (microarrays) for about 10 years. You are completely missing the point that the problem here is not the amount of information that a doctor can potentially get from the full genome sequencing. The problem is that at the current state of the art we are unable to digest this information to a point where a doctor can act on it. The reason is that once you go beyond the simple Mendelian genetics, the interactions between different factors become exceedingly complex. You need to take into account multistate interactions of the genome sequence with epigenetic and environmental factors. In addition, having the genomic sequence will not solve your problem of not knowing what to look for. It will tell you even less about what kind of infection you have. In this case we don't really need to use the latest gadget to replace cheap, fast and reliable immunology tests? Kind of reminds me about the machine that says 'BING'.

    As it stands now, doctors have more information that they can process. So if your are looking for a revolution that is just starting look at technologies for integrating large amounts of 'fuzzy' information from patient records, medical textbooks and literature, and various medical test to produce accurate diagnosis. Technologies like IBMs Watson and the NIH sponsored i2b2 is the next big thing in medical care.
