  1. oh really? on Carbon Nanotubes Can Exist Safely Inside the Body, Help Treat Cancer · · Score: 5, Informative

    Another paper out this week seems to directly contradict that headline.

    What Dai (the Stanford professor) is actually claiming is that specially functionalized nanotubes gather at the back end of the digestive tract, and seem to dissapear. Pure nanotubes cause all sorts of problems. There's an important distinction there, but this is still good news for nanotube (and cancer) research.

  2. Re:free market needs competition on State of US Science Report Shows Disturbing Trends · · Score: 1

    I agree with your sentiment that the relative intelligence of scientists could be increased, but I think it's a problem of too many not-quite-smart-enough people rather than a lack of intelligent people.

    If the wages for an intelligent scientist are best for that person NOT doing what they're trained in, doesn't that show that there are not enough jobs in that area? That says to me that there are either too many people being trained for the available science jobs, or the people on Wall Street are the morons (Isn't there anyone intelligent studying economics who can do some data mining? Why do they have to hire people who spent 10 years studying something else? Why can't they just teach some business students the same math we physicists learn?).

    The job application process for many scientific positions reflects the abundance of available labor. Most research jobs for a new PhD in my field are filled without advertisement. The way you apply for a job is to send your CV out to as many people as possible. Hopefully one of them will need to hire someone and will find your name in the stack of CVs which have been sent to them. I've heard this from scientists at Intel, in academia and at national labs. That does not sound like a field which is suffering from a lack of talent.

    You're right that most people following my career path are not in it for the money, but just to be really clear: the wages are shit. I have made a higher salary working as an unskilled construction worker than I have producing high level, practical research in a business friendly field. Now, I can greatly increase what I make after I finish my PhD research. That still means I may make less than I would have had I gone into teaching high school science. Postdoc salaries at Berkeley, for example, start at ~$31000, which is less than the ~$35000 starting salary for teachers in Oakland (which is also a more stable job, and carries better benefits). Does that mean that postdocs at Berkeley are dumber than Oakland teachers, or that there is more competition to be a postdoc at Berkeley than to teach in Oakland?

    I'm not talking about late career scientists, who may have lots of job opportunities, but the number of newly minted PhDs versus the number of available jobs for that group. To own your own patents or do side consulting at that point in your career is very unrealistic. The job market is such that you must give up your rights to such things at this level, or risk competing for private funding with less risky, more well established scientists.

    Despite all that, I would continue to make my current crap salary if it meant I could keep working on cutting edge research I like, and salary will probably not be a big factor for me in deciding where I work next. It's partially that kind of mindset which causes these problems.

    Take all the scientists Congress just put out of work and get them working on solar fuels (biofuels are nice, but don't actually remove fossil fuel dependence). No extra grants until we get that.

  5. solar fuel is the way to go on Scientists Recycle CO2 with Sunlight to Make Fuel · · Score: 1

    Photovoltaics are great, and biofuel is nice, but why not just directly generate fuel from sunlight? I haven't heard of the particular technique the Sandia guys are using.

    The technique most people are using is based on titanium dioxide catalysis in UV light. Japan is crazy for this stuff. It oxidizes pollution, makes it easier to clean buildings and windows and breaks water into oxygen and hydrogen (it's also in paint and sunscreen). It also can convert (reduce) CO2 into alcohols or methane in the right kind of atmospheric conditions, unfortunately not our atmospheric conditions. For the last 10 years or so, a few people have been looking at new crystal structures and dopants to enhance its efficiency, sunlight adsorption and reductive properties.

    A big guy in this field is Masakazu Anpo, I think his papers describe all of the above.

    While this kind of technology gets going, you're going to see a lot of press releases talking about reducing emissions and increasing efficiency of fossil fuels, but the end goal is to replace fossil fuels.

    I agree completely.

    Unfortunately, it's hard to find scientists willing to get into politics. That's why we're not getting the direction and oversight we need, and why we don't have people in Congress who can speak intelligently to a scientist. ... but a congress of 100% scientists? I'd rather have the lawyers.

  8. Re:No science open source or otherwise without fun on Government Makes NIH Research Open Access · · Score: 2, Interesting

    To me, the underlying problem is a lack of scientifically knowledgeable political leadership. Politicians don't want to hear about this and don't understand it. It would be nice if some of them were knowledgeable enough to take a critical look at the ways priorities in the grant giving agencies are determined. And really, it would be GREAT if Congress could figure out whether we have too few or too many scientists being trained in this country. My feeling is that we have far too many for the level of government and private funding we have available. I would like to see some conservative goals for the number of government funded grad students in a given field per year to try and rein in excessive growth and encourage growth in overlooked areas.

    Of course, I don't have and probably never will have an NIH grant. Just because physics funding didn't double, doesn't mean we don't have the same problems.

  9. Re:No science open source or otherwise without fun on Government Makes NIH Research Open Access · · Score: 1

    Now that the US government has out-competed all the private basic science laboratories, we're kind of stuck.

    I would be thrilled to have a company telling me what to do and paying me for it, but why should they do that when some government (US, EU, China...) will pay for basic research and grant them patent rights on the resulting engineering?

    From one point of view, what we've done gives our companies an unfair advantage. From another, it's good business. That's why our science system is being duplicated in Asia and Europe.

    Has the government lost money on scientific research, or has the increased economy led to more tax dollars? Should the government be required to spend "political capital" to increase the economy, or does that just make sense?

    While I would love to get rid of PR saps and hedge fund assistants, I think you're underestimating how much solar power is available. A square about 500 km on a side with 10% efficient solar cells would provide the United States with the same amount of energy (not just electricity) we use today. That's not a very big area at all compared to the amount of farmland we use, which is itself not very big compared to the amount of land available. Wise land use in the US alone could provide the world with a gluttonous energy budget... assuming we make it past the next few decades.

    While things may be rough on them in the short term, in the long term we'll have to find something other than energy scarcity to get rid of useless people for good.

    So... scientists already give up substantial rights to their work to publish papers. This has led to less financial incentive to become a scientist, but has created intense competition for respect and citations. Opening up the publications will further encourage the current system of citations-as-scientific-currency that exists.

    Those are some nice straw man arguments. There isn't a rule against selling tickets to Asians, there is a law against large markups on ticket re-sales and a contract with ticket holders to re-sell tickets with approved brokers. StubHub had a choice to claim that either they were violating the law by re-selling tickets well above the printed price or that their users were violating the law by selling the tickets above the marked price. (Unlike copyright, this law refers to a limited commodity... this is more like insider stock trading than online music trading.)

    The real problem is that StubHub really was encouraging people to break the law (and ticket agreement), they should be capping the re-sell ticket price to the printed price plus the legally allowed markup. They're a business devoted to ticket resale, they should know and follow the rules. It would be harder for the Patriots to get StubHub to turn over the names of people who have simply violated a private contract.

    The Wall Street Journal headline is a tautology. (Note that he's not talking about scientific misconduct, only honest mistakes, incorrect analysis or experimental design which could be improved.)

    There are almost no areas of science we're "done" with. The most recent paper on a subject almost always points out where previous papers have gone wrong. Thus, the previous papers have some mistake such as a miscalculation, poor design or incomplete analysis. If you pick any paper published in a peer reviewed journal this month, there's a very high probability that at some point in the future it will be amended or improved by some other paper.

    What Ioannidis *has* shown in his recent reports is that in genetics, not enough people are publishing on the same subjects. There are not enough "other papers" out there to check on the previous ones.
