LCMS Finds Cocaine on Euros

This Analyst article on LCMS for the determination of drug contamination on Irish euro banknotes by Jonathan Bones, Mirek Macka and Brett Paull at the Dublin City University National Center for Sensor Research has been getting quite a bit of press. Trace cocaine was found on all 45 bank notes tested. This is perhaps not surprising, given the ease with which the powder is spread by ATMs and counting machines. Nonetheless, the authors report a significant sensitivity improvement in the LCMS method compared to previous GCMS studies.

Rays of Positive Electricity, Second Edition

I blogged a while back about Thomson's 1913 Rays of Positive Electricity, which is available on-line in various formats. I recently found that the 1921 Rays of Positive Electricity Second Edition is also available. Thomson notes in the preface that

The hope expressed in the first edition that the method of Positive Rays would be of service in connection with important chemical problems has been fulfilled to a remarkable extent by the researches of Mr. Aston and others on the determination of atomic weights and the detection of isotopes. I am convinced that as yet we are only at the beginning of a harvest of results which will elucidate the process of chemical combination, and thus bridge over the most serious gap which at present exists between Physics and Chemistry.

I am trying out a Wiki version of the 1913 book. It looks good, but the markup is time consuming.

Peer Reviewing Wikipedia

One of the most often heard responses to complaints about incorrect information in Wikipedia is "Stop complaining and fix it." But many of those who would be willing to fix it are turned off because Wikipedia can be anti-expert with Byzantine rules of conduct that favor the rude and determined. Fixing Wikipedia doesn't work if your contributions are removed in an edit war. Some people thrive on that kind of contest, but most academics prefer a review by their peers and, when faced with the reality of Wikipedia, choose to opt out.

But the Wikipedia vs. peer review dichotomy is a false one. Since the material on Wikipedia is available through the GNU Free Document License, anyone is free to take any fraction of Wikipedia behind a peer review firewall as long as the peer-reviewed material is itself made available through the GNU FDL. Trying to peer review the several million Wikipedia articles is a Herculean task but peer reviewing the fewer than 100 Wikipedia articles on mass spectrometry is quite reasonable, especially if you are familiar with the Mediawiki software.

I have been using Mediawiki for a few years now and serve my group webpage and MS Terms site with the software. It was fairly easy to create a Mass Spectrometry Wiki and pull the pages from the Wikipedia mass spectrometry category into it. Mediawiki is set up for interwiki links, so it is trivial to direct non-mass spectrometry links from the articles out to Wikipedia. Since I have the administrator password, I am now the Benevolent Dictator of the pages in the Mass Spectrometry Wiki. Since I am pro-expert and anti-anonymous editing, I have the wiki set up so that only logged-in users can edit pages and only existing users can create user accounts. If you are a mass spectrometry expert, contact me and I will set up an account for you with your name and contact information. If you like the Wikipedia way, edit Wikipedia. If you want to be your own Benevolent Dictator, set up your own Mediawiki installation or find a site that does Wiki hosting.

Taken to the extreme, there could be dozens of competing wikis with mass spectrometry or other information and various editing philosophies. In this situation, the goodness of the information is a function of the trust that the reader has in the provider of the information, not the ease with which the information is obtained.

Open Access: ACS and ASMS

BioCurious Blog comments on American Chemical Society President E. Ann Nalley's recent letter arguing against open access to journal articles that report on research funded by the NIH. Nalley objects to the "available after six months" policy, arguing that it will lead to lost revenues. It's still too early to guage the effect on journal profits, but all issues of the Journal of the American Society of Mass Spectrometry are openly availble after one year. The flip side of open access is that it may lead to increased readership and higher impact factor, both of which can increase publisher profits.

Wikipedia: Mass-to-Charge Ratio

There is an interesting mass-to-charge ratio discussion on Wikipedia that illustrates a point I brought up in my ACS presentation last month (see also the Nature/Wikipedia/Britanica imbroglio). Wikipedia is open to editing by anyone and is peer reviewed only if ones peers choose to review and edit it. It will be interesting to see whether the scientific community embraces or rejects (or some combination) the open source approach to scientific information on the internet.
