DDW4: Day 27

I asked Koch to take pictures of the plants for me while I am out of town. Here are his notes regarding the experience:

Wasn’t sure of your camera settings. I had trouble with depth of focus, so I chose aperture priority (“A”)
and F=22, which seemed to work OK. I didn’t want to change your zoom, so I didn’t. I took pictures of bottoms
until half way through when I realized to take tops too (so two pictures each for arabidopsis). This was a
mistake, but since I don’t know if the photos are useful, I’m stopping now.

Photos are labeled TYPE CUVETTE_NUMBERS UP/DOWN and I left in the actual photo number, as follows

1 VG cuvettes 1-3
2 VG cuvettes 4-6
3 VG cuvettes 7-9
4 VG cuvettes 10-12 (DI, TAP)

5 H cuvettes 1-3
6 H cuvettes 4-6
7 H cuvettes 7-9
8 H cuvettes 10-12 DOWN (DI, TAP)
9 H cuvettes 10-12 UP (DI, TAP)

10,11 CA cuvettes 1-3 UP, DOWN
12,13 CA cuvettes 4-6 DOWN, UP
14,15 CA cuvettes 7-9 UP, DOWN
16,17 CA cuvettes 10-12 DOWN, UP (DI, TAP)

 

Thanks Koch for the help!

Scientific Publishing for the Modern Scientist

I posted last week that Steve and I were thinking about our avenues for publication. We basically weighed whether we should go the traditional route to publish in a peer review journal or just skip all that and write up an article and just post it here in my notebook or some other easily accessible location that is search engine optimized. After receiving feedback from Bill Hooker, I’m leaning towards a more traditional post, but I started thinking about all the options available to me and it made me excited for the future of science publishing.

As much as it pains me to say, closed peer-review publication is not going away anytime soon. This option will be available to scientists for at least the next 5 years (I wanted to say a longer time, but I am holding out hope that the 99% will topple the 1% when it comes to access to information). Right now there is a working business model for publishers and as long as that doesn’t change, neither will the method. But that doesn’t mean all is wrong in the world, after all we are shifting towards…

Open peer-review publications, with PLoS leading the charge and many other publishers following suit. As I understand it, to go this method, a scientist must front the money to have an open access article and publishers supplement that income with ad supported revenue (like every other online business). Hopefully publishing costs come down so more scientists would be inclined to travel this road. The more that scientists will request this kind of access to their information, the more change we’ll see on this front.

I personally feel that something like 90% of scientific information (discoveries?) will be published via one of the two options above for at least the next 20 years, with open access publishing quickly leading the charge in about 5 years. That is all subject to change of course because of how social media has changed traditional methods of communication and journalism. As younger scientists become PI’s and research scientists, the shift will happen and hopefully sooner than my time frame.

But what about the 10% that I left out? Surely there will be those of us who will want to pursue other avenues of publishing scientific discoveries to push the boundaries of scientific knowledge. I myself am one of those scientists and am constantly looking for ways to push the envelope. As Bill mentioned in a comment on anther post, I may be doing this for the sake of rebelling, but even if that is the case at least someone is rebelling!

But what other avenues could there be?

Well the best thing since sliced bread is going to become open notebook science! As people want to understand more about the world around them, they have turned to search engines to find answers. And those search engines point everyone to mostly the right places for their answers, Wikipedia being one of the largest sources of knowledge. But now there will be results from new unknown websites that come up in the top 10 for search results. Those links will direct visitors to notebooks of real scientists performing real research in real time.

Get real!

Oh I am! And the visitors will have access to (hopefully) accurate and scrutinized data that would be more reliable than waiting for a journalist’s understanding of the latest and greatest experiment.

To me, open notebooks lead to self publication. Google Scholar searches millions of sites for publication type documents. They will want to stay in the forefront of searching (so they can make money off advertising) and will begin to search notebooks for publication type articles as well. And once scientists learn that their information will be even more accessible because of search engines, I feel they will shift towards this method of publication, but ever so slowly.

With self publication I could see a scientist writing a formal review of the latest batch of experiments he has posted in his notebook, complete with links to the appropriate posts about methods, preliminary and revised data, and personal thoughts. After the review is complete he/she could post the “paper” to his notebook/personal site and open it up to public scrutiny.

There is an important aspect to this that I have yet to mention. A scientist should have a decent network for communication. If this is the case these would be the people that you would most rely on to criticize your newly published paper. All comments and revisions would be publicly accessible via the notebook. I’d like to point out that sites like this exist now and aren’t terribly successful, but hopefully this will change in the future.

An easier way to self publish would be to write your publication and then post it to an online repository like Scribd or SlideShare. These sites are pretty active communities of people who share documents and presentations much like youtube users share videos. In all honesty, I have no idea how users find information on these sites, but I have documents on both sites (scribd and slideshare) and somehow they do. I could very easily see someone using this in conjunction with other self publishing methods to maximize their reach.

But what if you really wanted to think outside the box? Everyone seems to be shifting from actual books to electronic versions of these books. Online stores like Amazon and iTunes have made it easy to publish an authored work with next to no expense from the author. Could scientists take advantage of this somehow?

Before you jump on me and demand the answer to be no, think about this. By publishing with Amazon (for example) you could charge $0.10 per download. This would ensure you cover costs with the online publisher and allow for maximum accessibility (without it being free). Sure you are inducing a cost to the reader and science isn’t about making money (to some people), but you could fund your lab with the revenue generated from these nearly costless purchases. 1000 downloads is $100 which is a small piece of equipment, 1000000 downloads is $100000, which is a very nice piece of equipment!

Obviously the idea isn’t perfect but it could have some potential great benefits if worked out well enough.

Keep in mind that most of the ideas here haven’t even been explored yet. Right now everyone publishes in some sort of peer reviewed journal whether it is open access or closed access. And also note that these are just some ideas from a potentially insane young scientist, but they aren’t pipe dreams either. There is a very real chance that self publications are going to appear and soon!

I, personally, look forward to being one of the pioneers of this reality, very soon!

FTIR data on FigShare

I’ve uploaded the data to FigShare so that makes me cool!

The next phase of this experiment would be to setup some sort of equipment training for Alex and myself and to get room access. This way we could schedule ourselves to use the machine and not have to burden Stephen for his time.

Then I think I want to organize the experiment so that we take data perhaps once a week with a sample of DDW and a sample of D2O that are left out for several weeks. Then we can compare the samples over time to watch as the deuterium content adjusts to become similar to normal water.

I suppose I should also analyze a sample of tap water and compare that to the DI and DDW samples. Tap water would have more contaminants in it than either of those two samples and hopefully those would show up in the FTIR results. I do have to say that I’m surprised that the 3-month old DDW sample had the exact same profile as the DI water sample. That made me feel more certain that DDW is probably made from DI water first.

Anyways here is the open data:

FTIR study of differences between D2O, DDW, and DI water

Stephen Myers from the NSMS department graciously helped Alex and I out with the next phase of the FTIR experiment. He was able to get a hold of a couple of quartz cuvettes from Spectrocell. On top of that I had ordered one from Amazon.

The first part of the experiment required us to “blank” the samples so we put a Spectrocell cuvette into the FTIR machine and took a reading. For fun we then did the same thing with the Amazon cuvette and then compared the two curves.

Amazon cuvette overlayed on Spectrocell cuvette

While the two graphs look identical we noticed that the sample from Amazon had a weird periodic feature in the graph. Stephen said in other experiments he attributes this pattern to some kind of film, whether or not that is what is going on here is debatable. Regardless I decided to use the Spectrocells for the remaining experiments.

Before we began I thoroughly rinsed each cuvette with DI water and dried with nitrogen. This did not remove all the liquid water, but most of it. I attempted to air dry the remainder. This is important information for later. I used 3mL of each water type (DI, DDW, D2O, and a D2O/DDW mix) for analysis in the FTIR spectrometer. For the D2O sample and for the D2O/DDW mixture I used the second Spectrocell cuvette (which was not blanked) so that the high D2O content wouldn’t contaminate the DDW samples. I used the same cuvette for the DI, and two DDW samples (I’ll explain this in a second).

We took spec readings in this order: (first) DI water, D2O, DDW, D2O/DDW mix, (last) old DDW. I chose this really random order because we weren’t sure we would be able to get any interesting data so I wanted to see DI water vs D2O first. When that gave us obvious results we tried the first DDW sample (taken from a bottle that was opened 11/30/11). Then I wanted to compare all these results with a close to 50/50 mix of D2O and DDW (I didn’t pipette exactly 1.5mL of each nor can I report on how close to that number it is, I was merely trying to determine if there would be a difference between DI, D2O, and a mix of those two with a larger percentage of D2O). Finally we measured a sample of DDW that was taken from a bottle that was opened 9/6/11.

Here are those results.

Comparison of DI, D2O, 2 samples of DDW, and a D2O/DDW mix sample

Wowie zowie! The data display isn’t ideal (done in excel quickly) but you can see a difference between each of the samples. There is one exception that is actually remarkable. The sample of DDW from 9/6/11 matches really well with the sample of DI water. The newer sample of DDW (11/30/11) is more distinguishable from these two than it appears above. And the mixed sample and that of pure D2O are very distinguishable both from each other and from the other samples!

If you notice that just above 1.5um (wavelength) there are two tiny humps in the data. I have blown that up below.

Zoomed in portion of the graph above from 1.5um to 2um. Note the sample of D2O is not in this graph.

Here there isn’t much different between the DDW samples and DI sample, but there is a difference between those and the DDW/D2O mixed sample. I didn’t include the D2O sample because the transmission in this range was much larger than these samples.

Now for the best part: Stephen was totally shocked that we were able to notice these differences. He wasn’t expecting much and frankly neither was I (I had been expecting to not notice anything because most papers I had read focused on the MIR range for FTIR). I was super stoked about these results, and happily, Alex was as excited about these results as I was/am!

I uploaded the graphs to Google Docs and all the data can be accessed here. I’ll upload the data to FigShare and link to that later.

Update: I forgot to mention that we are using a Nicolet 6700 FTIR spectrometer from Thermo.

Update (12/25/11): Fixed link to data. Thanks Koch

DDW4: Day 15

I can’t tell in the havanna seeds sample, but the virginia gold tobacco seeds in di and tap have tiny hairs. This is not alarming because I noticed this in prior trials. It is obvious that the hair growth in the ddw samples far exceeds that of the growth in these two samples.

Should I write a formal peer reviewed article on the plant-ddw experiments?

I guess the real question is: Should I submit a paper for peer review? I’m 100% going to write up the findings of these experiments and I’ll write it in the open, but should I submit the paper to an open access publication like PLoS for peer review?

Personally I could go either way. I know that it is useful for my career because current measures heavily favor peer review publications. And I know that it would benefit Koch in his career, but he has given me the freedom to choose what we do with these studies.

And honestly I don’t care about how the current system rewards peer reviewed publications. If this was the year 2030 I could probably just leave a copy of the paper here in my notebook and submit it to Google Scholar search results (which I should make a short post about). At that time (hopefully) the scientific community won’t be afraid to openly critique a publication, but now there is some kind of invisible barrier that prevents this kind of interaction.

If I did this now it wouldn’t be peer reviewed by anonymous reviewers, but I could say send it out to various colleagues and have them review and comment and self publish the comments.

I actually would like to do it this way. I think it would be a worthwhile experiment in open science publication. I’m not afraid of the criticism that I may receive from peers. I’m also not afraid of the impact it could have on my career, if indeed this is not well received. Eventually someone is going to have to make a bold leap, why can’t it be now, and why shouldn’t I make that leap?

On the other side of the coin, I’m not afraid of the current model either. I’m not opposed to publishing in an open access journal like PLoSOne, but I don’t see the value in a closed access journal. With an open access journal I would receive the benefits of open access and the benefits of peer review, the best of both worlds, so why shouldn’t I publish this way? I would get the career benefit that everyone expects to see on your resume and the joy of having shared my knowledge openly with all the world.

So then why do I feel inclined to go against the grain? Why do I feel like it would be a worthwhile risk to publish in an unorthodox way?

Am I crazy?

 

Backing up WordPress

For those of us who are self hosted we have to worry about archiving and protecting our notebook data. WordPress (along with other CMS software) in particular is constantly evolving and you may install a bad update or you may tinker with the code and disrupt a process. You may even get hacked which may destroy your system. While these are some doomsday scenarios there are in fact many reasons why you should backup your notebook and infinitely more reasons that are unknown.

Lucky for us WordPress has a great tutorial system and is widely documented on the web, so backing up is a breeze. You can do this manually or automatically depending on your preference. I chose to do it manually since I didn’t have time to setup an autoschedule. WordPress needed an upgrade and I wanted to get a backup of my posts just in case.

Here is a great place to get started.

My site is hosted by Bluehost and as such I’m able to follow the general protocol for using the cPanel and phpMyAdmin. The cPanel is a nice GUI for accessing server software, scripts, calls, etc. Instead of needing to understand command line prompts to interface with the server, you just point and click! phpMyAdmin is similar but for databases. cPanel gets you to the phpMyAdmin software and from there you can look at the back end of your databases. I don’t know much about this yet (but my dad knows a ton and so I’ll be picking his brain a lot).

But I do know that from phpMyAdmin it is very easy to get to the wordpress database. Once I got there I just clicked export database and away it goes, right to my computer.

I also needed to download the entire IheartAnthony site, because downloading the database doesn’t download images and other media which in my case are essential to my notebook. Doing this was easy. In cPanel there is an icon that takes you to the Bluehost backups (they host their own backups of everyone’s site just in case) and you can download the last nightly, weekly, or monthly backup. I opted for the most current so that I would have all of the most up to date information.

If you want to know, my site is 3GB which took a considerable amount of time.

So now I have my notebook backed up and I want to know what to do with it. It would be beneficial to have backups in more than one location and currently I can have 2: one on the KochLab server and one on my home machine (and I guess one more on my work laptop which is where I have the one right now). I would also like to have this notebook archived in the WayBack Machine for access to it in the future if I’m dead or the notebook is no longer active (or deleted). In fact this should be a priority for all open notebooks, since data curation is a major question mark right now.

Also, should I make a copy of my backup open? I’m inclined to think yes because when you are open everything should be open, but I don’t know about what possible ramifications I should be aware of. Any ideas? If this is a viable option, should I throw the copy up on GitHub?

DDW Effects: Paper Recap Roundup

Sinyak, Y.; Grigoriev, A.; Gaydadimov, V.; Gurieva, T.; Levinskih, M.; Pokrovskii, B. Deuterium-free water (1H 2 O) in complex life-support systems of long-term space missions Acta Astronaut. 2003, 52, 575– 580

This is actually kind of a strange paper as it seems to be a broad study of DDW effects on life but is awkwardly constructed. The goal is to show that their method is viable for producing deuterium reduced water on a space vessel and then they test its effects on arabidopsis and japanese quail. I don’t get it but whatever.

They created their own system of deuterium depletion via an electrolysis setup using distilled water. They then (presumably) used this ddw for their biological experiments. The results are summed in a table that basically says that arabidopsis grew way more in ddw than in di water and water with increased deuterium. For the quail, their results show that the bird and internal organs had increased mass over their distilled water.

I’m not sure what to make of these results nor do I know how reliable they are, but if they are true I have to say that they may coincide with my results. If the curviness of the roots/stems is a true morphological phenomenon, then that would mean that my plants are also displaying increased growth (longer stems, more mass, longer length). But this is just an observation. But I think I should weigh the samples for the next round of experiments.

This paper is a nice throw-back to the Lewis papers 40 years before it, in that it is really short and easy to comprehend. They find that seeds grown in DDW begin germination much faster than seeds grown in distilled ocean water (SMOW, that I’ve mentioned before). They of course had to be a bunch of fancy pants (pantses?) by getting their water from frozen Antarctic ice (a bit redundant on my part). They finish up by citing a paper that determined ddw increased the yield of cucumbers, radishes, and spring wheat. Interesting.

My results have not determined this to be true, but I also haven’t yet done an in-depth time analysis, which I will soon.

Link

I haven’t read this paper in full depth yet but I skimmed it and the gist that I got was that ddw enhanced survival of trout roes, which the authors think is due to enhanced motility of the sperm in ddw.

The interesting thing about all these papers is that none of them use full DDW (the stuff I’m using is Seki, K.; Usui, T. Process for promoting growth of agricultural products and aquatic animals, and for treating pancreatic disease, involves using deuterium-depleted water having specific deuterium concentration. Patent JP2005328812-A, 2005

Link

This is a patent and I could literally only find what I linked in the Google Search there. The hilarious thing is that there is another patent (from the same authors) that claims they can use DDW for weight loss. Now I’ve just cued new Google results for ddw and weight loss and am just adding to the histeria.

Dear confused Google Searcher,

I am in no way endorsing using deuterium depleted water as a weight loss supplement. In fact my research (and that of a few others) shows that ddw may in fact have an adverse affect in this regard. Do not just start drinking ddw or d2o if you: (1) are trying to lose weight, (2) are trying to fight cancer, or (3) are trying to be healthy in some other way.

Real Scientist

This just goes to show you one of the flaws with the current standards of research. While patents are useful to some, many researchers today will just patent every idea they have in an attempt to make money off it somehow. The weight loss patent proves that point! Rant over…

Back on point, I’m not sure how to access any more information than I’ve already found (which isn’t much). This may be the nature of the process since it’s an international patent and as such may not make for a useful citation. Oh well.
