Open Access Publishing Rip Off

I'm a big fan of information wanting to be free, and so naturally open-access publishing (i.e., the practice of not charging for access to publications) strikes a resonant cord with me. That's all fine, but what I would really like to know is, why do most open-access publishers need to charge such absurdly high prices for publication? The costs should cover posting a pdf (and optionally html version) of the submitted (and accepted) manuscript on a web server, so why should that cost upwards of $2500 per publication to do? Just look at the publication costs at PLoS (Public Library of Science) and BioMed Central for examples of these shenanigans, which in my opinion amounts either to 1) extorsion (in the 'rip off' sense), or to 2) a bribe for publishing articles of questionable quality (I've seen a lot of crap published, even in respectable journals, but it seems to be particularly prominent in open-access journals; someone should do a study on this phenomenon).

It should be emphasized that these outrageously high prices take away from funds that could otherwise be spent on research. That is, the publishers who charge these high prices in the name of "open-access" are doing the research community a grave disservice because they make considerably less money available for research. Don't these over-priced publishers have any ethics? That's what I would like to know! It seems all they care about is making a buck even if it means that potentially life-saving research will be negatively impacted by their foolish greed.

PLoS is the worst offender here. If you want to complain, try emailing plos@plos.org (or for BioMed Central, try info@biomedcentral.com). These organizations should be made aware that publishing quality peer-reviewed content doesn't meant that you need to rip off the authors and steal from research funds.

So what's the solution? Open-access publishers are of questionable significance. Most likely, you won't even notice them and don't care. Really, I don't much care myself for them, though it bothers me somewhat that they promote open-access and free information, while at the same time trying to rob you blind. My suggestion: just don't even bother with them until they wisen up. Submit to regular journals that do not charge you money for publishing your work (just make sure that most universities subscribe to them). If you still want to make your information free, just do what countless other scientists do and post pdf's of your manuscripts on your personal website (and make sure that Google indexes the content so that other people can find it through Google Scholar).

Bottom Line:  Good journals should not overcharge authors for publishing their work (and most do not charge at all). It is the privilege of the journal to publish quality scientific work (and not the other way around). To abuse this privilege is to foment discontent and invite disaster (in the form of said journals fading into insignificance or a lifeless existence). If PLoS and BioMed Central do not wisen up to this fast (and in addition, improve quality control), then this will be their fate.

Universe as Neural Net?


Does the large-scale structure of the universe resemble a big neural net? Yes, I know it sounds somewhat ridiculous, but I couldn't help making the association when I saw these pictures of the large-scale structure of the universe. What would be the implications of a universe-wide intelligence made explicit in the large-scale structure of the universe and its interactions?!

Ok, I'm being somewhat tongue-in-cheek here, but the reticular large-scale structure of the universe does bear striking similarities to the reticular organization of the nervous system.


Project Description:
The Virgo consortium, an international group of astrophysicists from the UK, Germany, Japan, Canada and the USA released in June 02, 2005 the first results from the largest and most realistic simulation ever of the growth of cosmic structure and the formation of galaxies and quasars. In a paper published in Nature, the Virgo Consortium showed how comparing such simulated data to large observational surveys can reveal the physical processes underlying the build-up of real galaxies and black holes.

The "Millennium Simulation" employed more than 10 billion particles of matter to trace the evolution of the matter distribution in a cubic region of the Universe over 2 billion light-years on a side, in the largest ever model of the Universe. It kept the principal supercomputer at the Max Planck Society's Supercomputing Centre in Garching, Germany occupied for more than a month. By applying sophisticated modelling techniques to the 25 Terabytes (25 million Megabytes) of stored output, Virgo scientists are able to recreate evolutionary histories for the approximately 20 million galaxies, which populate this enormous volume, and for the supermassive black holes occasionally seen as quasars at their hearts.

"It is the biggest thing we have ever done," said Carlos Frenk of the University of Durham. "It is probably the biggest thing ever in computational physics. For the first time we have a replica universe which looks just like the real one. So we can now for the first time begin to experiment with the universe.

Virtual Microscopy a Disruptive Technology?

Virtual microscopy is a method of posting microscope images on, and transmitting them over, computer networks. This allows independent viewing of images by large numbers of people in diverse locations.

Prior to recent advances in virtual microscopy, slides were commonly digitized by various forms of film scanner and image resolutions rarely exceeded 5000 dpi. Nowadays, it is possible to achieve more than 100,000 dpi and thus resolutions approaching that visible under the optical microscope. This increase in scanning resolution comes at a price; whereas a typical flatbed or film scanner ranges in cost from $200 to $600, a 100,000 dpi slide scanner will range from $80,000 to $200,000.

Virtual microscopy has been characterized as potentially a disruptive technology. A disruptive technology is a new technological innovation, product, or service that eventually overturns the existing dominant technology in the market, which in this case would be real (i.e., conventional) microscopy. Our experience with virtual microscopy suggests that it is unlikely to replace real microscopy any time soon, but for the time being, it nicely complements and extends the capabilities of real microscopes. Specifically, we find a three-fold extension of virtual microscopy over real microscopy in the following areas: 1) data-sharing and remote access, 2) data-management and annotation, and 3) data-mining. Data management and data-mining of virtual (digitized) slides are capabilities that cannot be directly applied to real slides. In addition, the online distribution and sharing of virtual slides with anyone with an internet connection ensures the rapid dissemination of neuroanatomical data that otherwise would not be possible. While largely emphasizing the pros of virtual slides in this article, it is worthwhile to point out the cons. Namely, it is not possible to change focus in a virtual slide as it is in a real slide. Normally, this is not a problem since virtual slides tend to be completely in focus. However, the inability to change the plane of focus in a virtual slide rules out their use in unbiased stereological estimation methods that require optical dissectors. Nonetheless, biased sterelogical estimation methods, or unbiased methods not using optical dissectors, are still possible. Another drawback is that the resolution of the virtual slide is limited to the optical lens used in the scanner. For example, if we generate a virtual slide at 20x and subsequently want to examine part of the slide at 40x, then it is necessary to rescan the entire slide using the higher objective, which in some cases, is not possible due to file size restrictions or hardware issues. Finally, at the time of writing, virtual microscopy does not deal well with fluorescence, and is only recommended for light microscopy.

Virtual microscopy-based digital brain atlases are superior to conventional print atlases in five respects: 1) resolution, 2) annotation, 3) interaction, 4) data integration, and 5) data-mining. The resolution of conventional print brain atlases typically does not exceed 7200 dpi, whereas virtual microscopy-based digital brain atlases attain 100,000 dpi and offer the ability to zoom in and out. Annotation can be more complete in virtual microscopy-based digital brain atlases, with options to display some types of annotations and make the rest invisible. Greater interactivity means that the user can zoom in/out and pan through brain image data, which is not possible in print-based atlases. Data-integration capabilities, including the integration of connectivity and gene expression data, are superior for the virtual microscopy-based digital brain atlases. And finally, the ability to data-mine virtual microscopy-based digital brain atlases is a feature not available for print-based atlases. While we do not foresee virtual microscopy-based digital brain atlases completely replacing conventional print-based brain atlases, we expect that they will be progressively more commonly used in place of print-based atlases.

What I'd like to know is, how likely is virtual microscopy to overtake regular microscopy and print atlases in the near future? In my opinion, conventional print brain atlases are a ripoff, often costing over $200 each. The idea of having this information freely available online is very tantalizing and welcome.
