Can I just express my love/respect for C. Titus Brown? Not only is he into openness in science and metagenomics and such. But he practices what he preaches. For example see – Daily Life in an Ivory Basement : /mar-12/diginorm-paper-posted in which he describes his new submission to arXiv and some background. I know I am big on Open Access and all, but even we have been lame about submitting things to preprint servers like arXiv. Gonne do my best to fix that and try and copy Titus.

Lenses in Biology collection from Nature Outlook: free (for now at least) & worth a look
Some nice long features in Nature Outlook on various topics plus interviews with the authors. Summed up in Lenses on Biology. All freely available though I think that is only for this collection and not in general for Nature Outlook.
Notes (from me and mostly others) from the JGI User Meeting #JGIUM7
OK, so the DOE Joint Genome Institute User Meeting is underway. Day 2 just finished. And I have been there for much of it but alas, not in some of the talks since I can’t seem to get past the hallway/gathering area outside the talks. There are way way too many people there who I have not talked to or seen in a while … So … apologies to those who thought I might be live tweeting the whole meeting … it just hasn’t happened. But I did use the Storify web tool to make a “storification” of posts to twitter from the meeting – most of which were from other people. Here is the story in slideshow format.

OMICS Driven Microbial Ecology …
Quick post here. Just discovered a nice review paper by Suenaga on targeted metagenomics: Targeted metagenomics: a high-resolution metagenomics approach for specific gene clusters in complex microbial communities – Suenaga – 2011 – Environmental Microbiology
This “Special Issue” on “OMICS Driven Microbial Ecology” has a series of papers, all of which seem to be freely available, of potential interest to readers of this blog including:
- Beyond the Venn diagram: the hunt for a core microbiome (pages 4–12)
- Omics for understanding microbial functional dynamics (pages 1–3)
- Microbial rhodopsins on leaf surfaces of terrestrial plants (pages 140–146)
- Photoautotrophic symbiont and geography are major factors affecting highly structured and diverse bacterial communities in the lichen microbiome (pages 147–161)
- Complete genome of Candidatus Chloracidobacterium thermophilum, a chlorophyll-based photoheterotroph belonging to the phylum Acidobacteria (pages 177–190)
- Metagenomic comparison of microbial communities inhabiting confined and unconfined aquifer ecosystems (pages 240–253)

Evolution rap: 3.5* til infinity #music
Well, after a rough day I am in need of some lightness. And thanks to Eric Lowe, an undergrad. working in my lab, I got a giggle out of this:
Elaine Mardis rocks: nice talk on "Next generation sequencing"
I wish I had seen this before I gave my first lecture on Next Gen Sequencing Methods on Monday. I will post mine later but here is a really really nice talk by Elaine Mardis from Washington University on the same topic:
Diabetes & H.pylori – a correlation but no known causation despite authors claims
Am having a hard time right now with the comments from the authors of this new paper showing a correlation between H. pylori presence and both type II diabetes and blood glucose levels. As far as I can tell, the paper does not show any causal connection. That is, they do not determine if H. pylori infection is a cause of blood sugar issues or a consequence of blood sugar issues.
Yet the authors of the paper, one of whom (Martin Blaser) is a very respected H. pylori expert are saying things like
“This study provides further evidence of late-in-life cost to having H. pylori,”
And they suggest that antibiotic treatment for the elderly may help prevent diabetes.
This to be seems to be a bit over the top. Yes, it makes sense that H. pylori could cause these issues. And they have a model for how it might. But they really should be more careful with their words until a causal connection is established. After all, we have many well known negative effects of antibiotic overuse, including some shown by Blaser. The last thing we need is people going out and dosing up on antibiotics in the hope that it will prevent type II diabetes. But I can guarantee that is what will happen if this story gets overplayed.
At least a few sources report on the lack of anything showing a causal connection (e.g. see US News and World Report):
An expert not involved with the study said that while it did not show a cause-and-effect relationship between the bacterium and diabetes, the findings suggest certain possibilities
But I am worried that that is not enough skepticism to counteract the claims of the authors here. The study is certainly interesting. And their model for a causal connection is fine. But they probably need to do a little bit of toning down of their claims here.
UPDATE: 3/17/13
After some people asked me questions about this study at a few recent meetings I dug a little deeper. And I am a bit startled to find out what the basis is for Chen and Blaser to claim a causative association between H. pylori and type II diabetes/ glucose levels. Here is a summary of their logic:
Helicobacter pylori is acquired almost exclusively in childhood [8], and there is no clear mechanism for how glucose intolerance present only after the age of 18 would increase risk of H. pylori colonization. It also is unlikely that H. pylori positivity and high levels of HbA1c levels share a mutual antecedent cause because there is no diathesis to both acquire H. pylori and to cause glucose intolerance.
They go on to discuss other lines of indirect evidence for why they think their conclusion is correct. And some of this is very suggestive. But “likely” and “suggestive” is not proof. There are many possible issues with their conclusion. In particular I think it is easy to come up with a scenario whereby something about the host (either their genetics or their history of exposure or even their micro biome) could influence both whether or not they get colonized by H. pylori or even whether or not they get colonized by particular strains of HP. And the same factor could influence microbiome interactions later in life. I see no evidence to indicate that H. pylori is the causative agent here. And for them to then basically recommend prophylactic antibiotics for elderly with HP seems dangerous at best.
California Breast Cancer Research Fund Tax Checkoff; wondering about Open Access policies
Just got this email below about what seems to be a worth cause:
March 8, 2012
Dear UC Colleagues, Throughout California and UC, researchers are developing new approaches to prevent, treat and cure cancer. I am writing you to share important information with those of you who will soon file your California state tax return. At the end of California Tax form 540, there is a section in which you can donate to two highly regarded cancer research programs that are administered by the UC Office of the President.
If you go to line 405, you can contribute to the California Breast Cancer Research Fund and if you go to line 413, you can contribute to the California Cancer Research Fund.
No contribution is too small, and 95 percent of contributions to these two programs via this tax check-off go directly to cancer research or community-based education.
Donations from line 405 go to our California Breast Cancer Research Program, which is renowned not only for its cutting-edge research, but also for working with community advocates and health care providers in targeting the issues and needs of patients and families, especially the underserved.
In recent years, donations from line 405 have supported critical research including: identifying environmental factors that potentially cause breast cancer; developing targeted therapies to block breast cancer from spreading to other organs; and improving support networks to empower patients as they maneuver the health care system. See this website for more information: http://cabreastcancer.org/taxcheckoff/
Donations to line 413 go to the California Cancer Research Fund, which is helping to provide prevention and awareness programs in communities disproportionately affected by cancer. One major ongoing project is increasing the understanding of the impact of tobacco use and cancer on vulnerable populations. This research could lead to reduced smoking, increased cancer awareness and strengthened prevention programs.
I wanted to be sure you were aware of this means of investing in research that can serve all Californians and our communities.
Sincerely,
Lawrence Pitts, M.D. Provost and Executive Vice President University of California, Office of the President
However, I wonder about the open access requirements of the fund. I sniffer around at their web site http://cbcrp.org/about/ and could not find anything about guaranteeing access to the results of the work supported by this fund. That is too bad – this seems to be a great case where openness could be both a good thing and a useful marketing tool (to get people to chip in money from their taxes).
Not sure what to make of this new "Datasets.Com" effort from Hindawi
Just got this email and I thought I would share. Not sure what to make of this effort. I do support the sharing of data sets but I am think we probably do not need a whole new cadre of data journals to handle this data.
But there is a spread of what some have called “Predatory” open access publishers (see http://metadata.posterous.com/83235355 for example). Hindawi, who is behind this, seems to have a mix of good and predatory tendencies and this seems like it may fit into the more predatory categorization. And I just thought it would be good to bring this a bit more into the open to discuss it.
Dear Dr. Eisen,My name is Safa Tahoon and I am a Journal Developer for the Hindawi Publishing Corporation. We are in the process of launching a new peer-reviewed, open access journal titled Dataset Papers in Genetics, which will publish Dataset Papers in all areas of genetics research, and I am writing to invite you to join the Editorial Board of this new journal.
Dataset Papers in Genetics is part of a new journal platform that Hindawi is developing called Datasets International (http://www.datasets.com). The main objective of Datasets International is to help researchers in all academic disciplines archive, document, and distribute the datasets produced in their research to the entire academic community. In addition to publishing a series of journals devoted to the dissemination of Dataset Papers, Datasets International hosts the underlying data behind these Dataset Papers and makes it accessible to all researchers worldwide.
The journal will be run using a collaborative editorial model which is designed to provide a fast peer review process for all submitted manuscripts. The journal will be edited by a distributed Editorial Board, and it aims for an average review time of 4 weeks from submission until a final decision has been reached.
Manuscripts that are submitted to the journal will be sent to a number of Editorial Board Members (typically each manuscript will be sent to at least 5 Editors), who will have two weeks to provide either a recommendation for the publication of the manuscript, along with a written commentary detailing any improvements that the authors should make to their manuscript, or a written critique of why the manuscript should not be published.
After the two-week period has elapsed, if the majority of the editorial evaluations recommend the manuscript be rejected, the manuscript will be rejected. If all the editorial evaluations that are received recommend that the manuscript be accepted for publication, the manuscript will be accepted. Otherwise, the editorial evaluations will be anonymously communicated to all of the Editors who participated in the peer review process. Each Editor will be given an additional week to review the feedback of the other Editors and to either confirm or revise their earlier editorial recommendations. If the majority of the editorial evaluations that are received by the end of this second round of review recommend the manuscript be accepted for publication, the manuscript will be accepted. Otherwise, the manuscript will be rejected. If the manuscript is accepted for publication, the names of the Editors who recommended the publication of the manuscript will be published alongside the ma!
nuscript. More information on the journal is available on the following web pages:http://www.datasets.com/ (Datasets International Home Page)
http://www.datasets.com/journals/genetics/ (Journal Home Page)
http://www.datasets.com/journals/genetics/workflow/ (Editorial Workflow)
http://www.datasets.com/journals/genetics/editors/ (Editorial Board)The journal will be published using an open access model, which allows disseminating scholarly articles by removing the access barriers imposed by the subscription model, in order to make the full-text of all published articles freely available for any interested reader. In this model the publication costs of an article are covered in the form of Article Processing Charges, which are publication fees paid from the research budget of accepted authors. In this model authors retain the copyright of their work, and we make every possible effort to ensure that the full-text of every published article is both visible and accessible to all potential readers.
Manuscripts that are submitted by the members of the Editorial Board of Dataset Papers in Genetics to the journal will automatically receive a 50% reduction in their Article Processing Charges.
Please do visit the web pages above and let me know if you have any questions or comments. We hope you will accept to join the Editorial Board of the journal and I will be looking forward to hearing from you soon.
Best regards,
Safa Tahoon
