I was happy to see that the authors published this article in PlosOne. I was following their work a while ago, but had lost track (plus, when asked, the last author implied that they had moved on to new projects). So here's the citation and then I'll summarize and comment. Divoli, A., Wooldridge, M., & Hearst, M. (2010). Full Text and Figure Display Improves Bioscience Literature Search PLoS ONE, 5 (4) DOI: 10.1371/journal.pone.0009619 The authors created a prototype information system that used Lucene to index the metadata for open access biomed articles, the full text, and the captions for images and tables. The interface is set up to allow you to use one search box and then radio buttons to select full text and abstracts, figure captions, or tables. In the first, the results are sort of like the standard metadata and abstract with key word in context excerpts and extracted images. For figure captions, you can either have a grid of figures, or a list. For tables, you get a citation, the table caption, and the table. The article spends a good deal of time discussing design decisions, providing a tutorial for creating your own. To build the prototype, they got the XML from PubMed Central, pulled out authors, images, captions, abstracts... They made different sizes of the images for quick retrieval later.They then included different fields with different weights depending on what you select to search. They then got a group of biologists (n=20 although number isn't really important for qualitative studies), and ran them through a study. The participants provided the query and looked at it in each view, thinking aloud about their reactions and steps. They were then asked a few questions about each interface The majority of the participants would choose to use this type of interface for at least some of their searching. Seems like they got the full text search, but were not quite as sure about the table search. Some thought it would be useful for getting right to the results but several didn't think they would use it. Now for some commentary... I was somewhat critical in my post I linked to above, but I really think this is promising stuff. The authors point out that this is very dependent on access to the full text and also won't be universally useful. There are plenty of search situations in which the images wouldn't be used, but they should be an option. Since my earlier post, CSA has added "deep indexing" to more of their files. It's not the same as their dedicated Illustrata product, which is more like Biotext. Publishers have the full text, so some of them are also making the images and tables available outside of the article. For example, both ACS and RSC have added images to their RSS feeds. ScienceDirect has a tables and images tab on their articles - which is nice for scanning to see if the article is relevant. PlosOne lets you look through a list of the tables and images, download a ppt or high quality image. Springer Images also lets you search the tables and captions to get pictures. It also indexes the context of the reference to the image in the text. You also get a link to the article and excerpts like on Google Books. My colleague at work pointed out that it is useful for finding phase diagrams. But more than all of that, there's been a lot of talk recently about disaggregating the journal article or even doing away with the whole and just using the pieces. If so, maybe this is an intermediate step. Read the comments on this post...... Read more »

Who better to interview the creator of BioTorrents than the creator himself? :)Interviewer: So Morgan, your article entitled “BioTorrents: A File Sharing Service for Scientific Data” was published today in PLoS One. BioTorrents uses the popular peer-to-peer file sharing protocol, BitTorrent, to allow scientists to rapidly share their results, datasets, and software. Where did this idea come from?Morgan: Well about 6 months ago I was downloading some genome files from NCBI's FTP site and was watching the download speed hover between 50-100Kb/s and I said to myself (much like this interview) I wish could download these with BitTorrent. I have used BitTorrent for downloading other non-scientific data (lets not discuss what they may be) and I know it is a much faster and more reliable way for getting large files. A few minutes later I posted to Twitter asking if anyone had thought about setting up a BitTorrent tracker for scientific data and the response was over-whelming (well only 1 response, but I could feel it had a larger impact). About a week later, I brought up the idea again over coffee with some members of my lab and more importantly my post-doc supervisor Dr. Jonathan Eisen. He thought it was a good idea and well worth pursuing, which was all I needed to push aside all my other "real" research and focus on this much more "fun" project.Interviewer: Thanks for that long-winded response. Maybe you could comment more briefly on the benefits of using BioTorrents/BitTorrent for sharing scientific data.Morgan: I think it is explained fairly well in the manuscript and in my previous blog post, but to reiterate the major benefits are:1) Faster, more reliable, and better controlled downloading of data that scales well for very large files.2) Instant "publishing" of data, results, and software.3) Very easy for anyone to share their data. No dedicated web server needed.Interviewer: Who should consider sharing data on BioTorrents?Morgan: Everyone that has something to share. Large institutions can benefit from reduced bandwidth requirements, while individual users can benefit from the simplicity of sharing with BitTorrent technology. Personally, I really like the idea of open data and the idea of sharing results before publication. How many times has someone done an all vs all blast of microbial genomes? In theory this can be done once, and that person can be recognized (referenced, co-authored, etc.) when other researchers use that data.Interviewer: Are there any challenges/limitations to using BitTorrent with scientific data?Morgan: BitTorrent excels at transferring very large popular datasets. Therefore, if only one person is "seeding" a file and only one person is downloading the file most of the advantage to using BitTorrent is lost. However, even in this worst case scenario, the transfer speed would be roughly equivalent to using traditional file transfer methods such as FTP/HTTP and BitTorrent still provides the benefit of error checking and ease of data transfer control (pause, resume, etc.). Another possible problem is that some institutions often try to limit BitTorrent traffic since it is often considered illegal non-work related network traffic. However, I would encourage users at these institutions to explain to their network administrator that many times BitTorrent traffic is legitimate and shouldn't be blocked.Interviewer: Why publish in PLoS One?Morgan: I have been a big fan of the PLoS One journal and ever since I blogged about it last year "Is PLOS One the future of scientific publishing?", I have been wanting to submit a paper there. Also, considering that BioTorrents is aimed at improving open access to data in all fields of science, PLoS One seemed like the most obvious journal choice for our manuscript.Langille, M., & Eisen, J.

It is widely assumed that 5 participants suffice for usability testing. In this study, 60 users were tested and random sets of 5 or more were sampled from the whole, to demonstrate the risks of using only 5 participants and the benefits of using more. Some of the randomly selected sets of 5 participants found 99% of the problems; other sets found only 55%. With 10 users, the lowest percentage of problems re-vealed by any one set was increased to 80%, and with 20 users, to 95%. [Faulkner, 2003]... Read more »

Today’s tip is on Genomicus. Genomicus is a great tool to visualize gene duplication, synteny and genome evolution. The search and display interfaces are quite straightforward, and there are lots of great features (viewing ancestral gene information, links out to resources, different views of phylogenies, etc) in the tool. This video is only a short introduction. You can delve deeper into the tool with the help and documentation, including an 11 minute video.
There is also a recent (advance access) paper in the journal “Bioinformatics” that will give you a lot more detail on how the database and tool works and what is there.

This study has nothing to do with drugs, psychotherapy, or even neuroscience. It's about Jesus' head; more specifically, it's about Jesus' head in relation to the size of the main course in 52 different depictions of the Last Supper.I know what you're all thinking, it's barely past noon, and I've hit the scotch too hard this time. From the International Journal of Obesity:"Portion sizes of foods have been noticably increasing in recent years, but when did this trend begin? If art imitates life and if food portions have been generally increasing with time, we might expect this trend to be reflected in paintings that depict food. Perhaps the most commonly painted meal has been that of Jesus Christ's Last Supper, chronicled in the New Testament of the Bible. A CAD–CAM analysis of the relative food-to-head ratio in 52 representative paintings of the Last Supper showed that the relative sizes of the main dish, bread, and plates have linearly increased over the past millennium."First, it's spelled noticeably, not noticably. No need to thank me, I'm just here to help.Lead author, Brian Wansink, proudly displayed his virginity by saying, "I think people assume that increased serving sizes, or ‘portion distortion,’ is a recent phenomenon, but this research indicates that it’s a general trend for at least the last millennium."His brother Craig Wansink, proving that mental illness does run in their family added, "As the most famously depicted dinner of all time, the Last Supper is ideally suited for review."Here is a graph showing some of the data that will one day lead to a vaccination for jock itch. I am posting another graph below because I hate all of you. What they found was that "the main courses depicted in the paintings grew by 69%, plate size by 66%, and bread size by 23%" over the course of 1000 years. I've lost precious minutes from my life.

This article discussed in this post, isn’t recent but the conclusion is very nuanced which isn’t always the case with publications especially in news media about social networking and kids or adolescents. Seems that politicians are advocating measures to restrict social networking for children in order to prevent assumed online sexual exploitation and Internet harassment.
