Snow in Amsterdam by Bas van GaalenLast Friday, the Centrum Wiskunde & Informatica (CWI) in Amsterdam hosted a workshop called Semantic Web Applications and Tools for the Life Sciences (SWAT4LS) 2009.

Following on from last year [1], the workshop proceedings will be published at ceur-ws.org and in a special issue of the Journal of Biomedical Semantics, but if you want to find out what happened in the meantime, take a look at the #swat4ls2009 hashtag on twitter. Twitter makes bloggers lazy (they blog less but tweet more), but thankfully Nico Adams has studiously blogged the workshop very extensively.

Disruptive Technologies Director (cool job title!) Anita de Waard from Elsevier was asking what were the conclusions of the workshop. So here is an incomplete summary: Roughly speaking, people agreed to disagree (again). Keynote speaker Barend Mons argued that redundant data should be eliminated through the use of “nano-publications” and micro-attribution in his entertaining but controversial keynote. Some people in the audience disagreed with this. Greg Tyrelle thinks that redundancy is a feature, not a bug, in the Web and we have to deal with it. Alan Ruttenberg argued that semantic web reasoners  are required to clean up and sanity check all the messy and noisy biological data but emphasised the importance of Computer Scientists learning to speak Biologists language.

The good thing about this workshop is its size: small, friendly but internationally attended. Thanks to M. Scott Marshall, Albert Burger, Adrian Paschke, Paolo Romano and Andrea Splendiani for organising another good workshop, hope to see you again next year (if not before).

Artemether: Entity of the Month

Filed under: biocuration — Duncan @ 1:27 pm
Tags: , , , , , , , , , , , , , , , , ,

ArtemetherNovember’s entity of the month at ChEBI is the antimalarial drug Artemether. This accompanies release 62 of ChEBI, not just yet another incremental release but an increase of more than twentyfold in the number of entities in ChEBI, thanks to merging of data between an updated ChEBI [1] and ChEMBL [2]. ChEBI now (as of release 62) has over 455,000 total entities, compared to just under 19,000 in the previous version (release 61), see ChEBI news for details. The text below on Artemether is reproduced from the ChEBI website, where content is available under a Creative Commons license:

Artemether (CHEBI:195280) is a lipid-soluble antimalarial for the treatment of multi-drug resistant strains of Plasmodium falciparum malaria. First prepared in 1979 [3], it is a methyl ether of the naturally occurring sesquiterpene lactone (+)-artemisinin, which is isolated from the leaves of Artemisia annua L. (sweet wormwood), the traditional Chinese medicinal herb known as Qinghao. However, because of artemether’s extremely rapid mode of action (it has an elimination half-life of only 2 hours, being metabolized to dihydroartemisinin which then undergoes rapid clearance), it is used in combination with other, longer-acting, drugs. One such combination, licensed in April of this year by the WHO, is Coartem in which the artemether is mixed with lumefantrine – a racemic mixture of a synthetic fluorene derivative known formerly as benflumetol – which has a much longer and pharmacologically complementary terminal half-life of 3–6 days, allowing the two drugs to act synergistically against Plasmodium.

The molecule of artemether is interesting because of its extreme rigidity, with very few rotational bonds. Unlike quinine class antimalarial drugs, it has no nitrogen atom in its skeleton. However, an important chemical feature (and unique in drugs) is the presence of an O–O endoperoxide bridge which is essential for its antimalarial activity, as it is this bridge which is split in an interaction with heme, blocking the conversion into hemozoin and thus releasing into the parasite heme and a host of free radicals which attack the cell membrane.

Artemether is fully Rule-of-Five compliant and has recently also been under investigation as a possible candidate for cancer treatment [4,5].

GO ChEBI!

Wellcome to the Genome Campus

Filed under: funding, informatics — Duncan @ 7:31 am
Tags: , , , , , , , , , , , , , , , , , , , , , ,

Henry Wellcome, Mr. PharmacistSo, I’ve just started a new job and moved home. There is loads to blog about but little time to do it. Before it’s too late, here are some first week impressions from a newbie starter at the European Bioinformatics Institute (EBI) on the Wellcome Trust Genome Campus.

The Genome Campus owes its existence to the pharmacist Henry Wellcome, pictured over on the left. When he died in 1936, his legacy founded the Wellcome Trust, set up with money from his success as a pharmaceutical manufacturer and salesman. Today, the trust is the largest charity in the UK, funding innovative biomedical research and spending over £600 million each year. A large part of this legacy is being (and has been) spent on the Wellcome Trust Genome Campus, home to the Wellcome Trust Sanger Institute (WTSI) (aka “The Sanger”) and the European Bioinformatics Institute (EBI) an outstation of the European Molecular Biology Laboratory (EMBL) based in Hinxton, twelve miles south of Cambridge in Cambridgeshire.

Cambridgeshire life: Good and Bad

It’s a bit of shock moving “Down South” from Manchester. Although still in the UK, sometimes it feels like a different country and culture to “Up North”. So I’ll have to resort to bullet points to cover the good and bad of life down here so far.

  • Bad: Middle of nowhere Hinxton, Cambridgeshire is the middle of nowhere - there is nothing else here apart from the Red Lion. There is not much choice of shops, pubs, eateries, curry houses and restaurants to visit at lunchtime. The nearest train stations are miles away although there is an excellent bus service. However, there is no escaping the fact that Hinxton is a pretty inaccessible compared to being in the centre of a city. Still, at least London is a short train ride away from Cambridge.
  • Bad: It’s Grim Down South Southern English prejudice often states that It’s Grim Up North, but this a topic of much contention. Northerners often think the converse is true, and have frequently pointed out that actually It’s Grim Down South, because life costs more but you get a lot less for your money. It all depends on what you mean by those weasel words less, more and grim of course, but that’s another story.
  • Bad: Norman-no-mates Being the newboy-with-shiny-shoes, I can’t help wondering where all my friends, colleagues and frolleagues went. I knew I’d forgotten to pack something in the move. I feel all lost without my pals from the Information Management Group (IMG), dbkgroup and the MCISB back “home” in Manchester. But I wouldn’t have got this job without them, especially the opportunities provided by Carole Goble, Robert Stevens and Douglas Kell. The only consolation is while we are no longer colleagues at the University of Manchester, we’re still colleagues at the Invisible College.
  • Good: Big, world class and international There’s something like ~300 people employed at the EBI and another ~800 or so at The Sanger. They come from all around the world, the ChEBI group for example currently has German, South African, Norwegian, Portugese, Chilean, Dutch and English nationalities amongst its number. So there is a lot to learn from the people around you, a high quality series of seminars to choose from and excellent support networks for various things, both technical and social.
  • Good: High profile and expert When it comes to bioinformatics this place obviously has a high profile and there is no shortage of expertise to draw on locally, both on campus and in the surrounding Silicon Fen.
  • Good: Canteen, gym, library etc There are some impressive facilities here, a well stocked library, extensive gym, sports facilities and huge canteen. They look after their employees too, little things like paying for removals when you relocate can make a big difference. There’s also tax benefits of working for a European organisation.
  • Good: Beautiful countryside and campus The south cambridgeshire countryside is quite beautiful with its rolling Gog Magog Downs. It’s looking good at this time of year, with hundreds of colourful autumn trees populating the 55 acres of landscaped parkland on campus.
  • Good: Best of both worlds The EBI is an academic institution (ebi.ac.uk) but it feels more industrial than academia in many ways. So you can (I hope) get the best of both worlds, academic and industrial.

Anyway, the Chemical Entities of Biological Interest (ChEBI) team of which I am now part are making me feel very wellcome here and I’m enjoying working on research and development of the ChEBI ontology [1]. It is interesting to wonder what a pharmacist like Henry would make of a freely available open source chemical ontology (describing many drugs) and the Genome Campus which bears his name.

Contemplating this question may require growing a long silken moustache which Henry Wellcome clearly excelled at, see picture top left.

Popular, personal and public data: Article-level metrics at PLoS

Filed under: publishing — Duncan @ 11:50 am

PLoS: The Public Library of ScienceThe Public Library of Science (PLoS) is a non-profit organisation committed to making the world’s scientific and medical literature freely accessible to everyone via open access publishing. As recently announced they have just published the first article-level metrics (e.g. web server logs and related information) for all articles in their library. This is novel, interesting and potentially useful data, not currently made publicly available by other publishers. Here is a  selection of some of the data, taken from the full dataset here (large file), which includes the “top ten” papers by viewing statistics.

*The rank is based on the 12,549 papers for which viewing data (combined usage of HTML + PDF + XML) are available.

**Citation counts are via PubMedCentral (data from CrossRef and Scopus is also provided, see Bora’s comments and commentary at Blue Lab Coats.)

Science is not a popularity contest but…

Analysing this data is not straightforward. Some highly-viewed articles are never cited (reviews, editorial, essays, opinion, etc). Likewise, popularity and importance are not the same thing. Some articles get lots of citations but few views, which suggests that people are not actually reading the papers them before citing them. As described on the PLoS website article-level-metrics.plos.org:

“When looking at Article-Level Metrics for the first time bear the following points in mind:

  • Online usage is dependent on the article type, the age of the article, and the subject area(s) it is in. Therefore you should be aware of these effects when considering the performance of any given article.
  • Older articles normally have higher usage than younger ones simply because the usage has had longer to accumulate. Articles typically have a peak in their usage in the first 3 months and usage then levels off after that.
  • Spikes of usage can be caused by media coverage, usage by large numbers of people, out of control download scripts or any number of other reasons. Without a detailed look at the raw usage logs it is often impossible to tell what the reason is and so we encourage you to regard usage data as indicative of trends, rather than as an absolute measure for any given article.
  • We currently have missing usage data for some of our articles, but we are working to fill the gaps. Primarily this affects those articles published before June 17th, 2005.
  • Newly published articles do not accumulate usage data instantaneously but require a day or two before data are shown.
  • Article citations as recorded by the Scopus database are sometimes undercounted because there are two records in the database for the same article. We’re working with Scopus to correct this issue.
  • All metrics will accrue over time (and some, such as citations, will take several years to accrue). Therefore, recent articles may not show many metrics (other than online usage, which accrues from day one). ”

So all the usual caveats apply when using this bibliometric data. Despite the limitations, it is more revealing than the useful (but simplistic) “highly accesssed” papers at BioMedCentral, which doesn’t always give full information on what “highly” actually means next to each published article. It will be interesting to see if other publishers now follow the lead of PLoS and BioMed Central and also publish their usage data combined with other bibliometric indicators such as blog coverage. For authors publishing with PLoS, this data has an added personal dimension too, it is handy to see how many views your paper has.

As paying customers of the services that commercial publishers provide, should scientists and their funders be demanding more of this kind of information in the future? I reckon they should. You have to wonder, why these kind of innovations have taken so long to happen, but they are a welcome addition.

Why don’t scientists share data?

Filed under: Science, communication, publishing, web of science — Duncan @ 2:28 pm

Sharing Ice Cream by ClappstarAs Vince Smith once put it [1] data are the fuel of Science:

“The fabric of science is changing, driven by a revolution in digital technologies that facilitate the acquisition and communication of massive amounts of data. This is changing the nature of collaboration and expanding opportunities to participate in science. If digital technologies are the engine of this revolution, digital data are its fuel. But for many scientific disciplines, this fuel is in short supply.”

Despite the importance of data, some scientists are often really bad at sharing it properly. So why don’t scientists share data?

Nature has a special issue dedicated to this topic published today at nature.com/news/specials/datasharing [2,3,4,5] which isn’t behind a pay wall (at the moment). It describes some of the technical and cultural barriers to data sharing. You should go and read it yourself if you’re interested, but here is a very brief and incomplete summary, with some extra points thrown in for good measure:

  • Some funding bodies do not adequately support the research projects they sponsor in sharing data properly, both before and after publication.
  • Many scientists lack awareness, incentives and knowledge of data sharing which can be compounded by a fear of being “scooped”.
  • Public databases, often a more natural home for data than traditional publications, are frequently undervalued by a publish or perish culture [6].
  • Traditional scientific publishing is frequently (and ironically) a really inadequate method for sharing data. Important data and metadata routinely gets damaged or destroyed in the process of publishing [7].
  • The technical infrastructure for long term data sharing either does not exist or is not understood by those who should be providing and using it. This can lead to empty archive syndrome.

These are some of the reasons that scientists don’t share data. Which raises the question, how do we get out of this mess? The special issue offers some solutions [3,4] to these cultural and technical problems, including the use of Creative Commons licenses. It’s good to see these important issues given a higher profile but we will probably be striving for better data sharing for many years to come.

XML Summer School 2009The XML Summer School returns this year at St. Edmund Hall, Oxford from 20th-25th September 2009. As always, it’s packed with high quality technical training for every level of expertise, from the Hands-on Introduction for beginners through to special classes devoted to XQuery and XSLT, Semantic Technologies, Open Source Applications, Web 2.0, Web Services and Identity. The Summer School is also a rare opportunity to experience what life is like as a student in one of the world’s oldest university cities while enjoying a range of social events that are a part of the unique summer school experience.

This year, classes and sessions are taught and chaired by:

W3C XML 10th anniversaryThe Extensible Markup Language (XML) has been around for just over ten years, quickly and quietly finding its niche in many different areas of science and technology. It has been used in everything from modelling biochemical networks in systems biology [1], to electronic health records [2], scientific publishing, the provision of the PubMed service (which talks XML) [3] and many other areas. As a crude measure of its importance in biomedical science, PubMed currently has no fewer than 800 peer-reviewed publications on XML. It’s hard to imagine life without it. So whether you’re a complete novice looking to learn more about XML or a seasoned veteran wanting to improve your knowledge, register your place and find out more by visiting xmlsummerschool.com. I hope to see you there…

Science Online London 2009Last Saturday, The Royal Institution of Great Britain (R.I.) hosted a conference called Science Online London (#solo09) co-organised by mendeley.com and network.nature.com. The event centred around the fantastic Faraday Theatre which according to the R.I. is a “beautiful, historic theatre [which] has deeply raked seating that creates an intimate atmosphere, even when full to capacity”. Absolutely. Just like last year, this event attracted delegates and speakers from a wide range of backgrounds in science, publishing and communication from around the world. This post is an approximately alphabetically ordered link-fest of some of the people involved. People are, after all, the most interesting thing about any conference. If you’re not listed here it’s not because I don’t like you (honest!) it’s because we didn’t speak or I didn’t listen or (unlike many people) you’re not vain enough [1] to have a have a blog (yet) :-)

Now I’m told the presentations mentioned above will be on Nature Precedings in due course, which will be good. Thanks to all the organisers, speakers and participants this year that made Science Online London 2009 well worth attending. Hopefully see some more of you again next year!

Escape from the impact factor: The Great Escape?

The Great Escape with Steve McQueenQuite by chance, I stumbled on this interesting paper [1] yesterday by Philip Campbell who is the Editor-in-Chief of the scientific über-journal Nature [2]. Here is the abstract:

As Editor-in-Chief of the journal Nature, I am concerned by the tendency within academic administrations to focus on a journal’s impact factor when judging the worth of scientific contributions by researchers, affecting promotions, recruitment and, in some countries, financial bonuses for each paper. Our own internal research demonstrates how a high journal impact factor can be the skewed result of many citations of a few papers rather than the average level of the majority, reducing its value as an objective measure of an individual paper. Proposed alternative indices have their own drawbacks. Many researchers say that their important work has been published in low-impact journals. Focusing on the citations of individual papers is a more reliable indicator of an individual’s impact. A positive development is the increasing ability to track the contributions of individuals by means of author-contribution statements and perhaps, in the future, citability of components of papers rather than the whole. There are attempts to escape the hierarchy of high-impact-factor journals by means of undifferentiated databases of peer-reviewed papers such as PLoS One. It remains to be seen whether that model will help outstanding work to rise to due recognition regardless of editorial selectivity. Although the current system may be effective at measuring merit on national and institutional scales, the most effective and fair analysis of a person’s contribution derives from a direct assessment of individual papers, regardless of where they were published.

It’s well worth reading the views of the editor of an important closed-access journal like Nature, a world champion heavyweight of Impact Factor Boxing. So their view on article-level bibliometrics and novel models of scientific publishing on the Web like PLoS ONE is enlightening. There are some interesting papers in the same issue, which has a special theme on the use and misuse of bibliometric indices in evaluating scholarly performance. Oh, and the article is published in an Open Access Journal too. Is it just me, or is there a strong smell of irony in here?

Josh the Java Junkie

Joshua Bloch at scifooOne of the people I enjoyed seeing at Science Foo Camp this year was Joshua Bloch. Josh is a Java Junkie [1,2,3] and software engineer at Google. When he wasn’t playing harmonica around the foo camp fire (see picture right), he was giving interesting talks about optical illusions, some of which can be found in his book Java Puzzlers. So I bought the book, and have been doing a puzzle a day to keep the doctor away. Most of the puzzles in this book are short Java programs that behave in ways you would not expect. The one below is a nice example:

public class Indecisive {
    public static void main(String[] args) {
        System.out.println(decision());
    }

    static boolean decision() {
        try {
            return true;
        } finally {
            return false;
        }
    }
}

What does this program do? Return true or false? Perhaps it does both or something else completely? Does it even compile? Can’t decide? Welcome to public class Indecisive…

How to be a Rocket Scientist

Filed under: Big Questions — Duncan @ 10:40 pm

Today, the 20th July 2009, is the 40th anniversary of the first lunar landing. There has been plenty of global coverage, stargazing, astronautical analysis and heavenly commentary recently. But for me personally, the Apollo 11 anniversary brings back fond memories of rocket science lessons [1] – specifically, the things I learned in Chemistry at school. Our teacher used to launch water rockets during classes and these hands-on demonstrations were followed with more down-to-earth calculations back in the laboratory. This was an entertaining way to learn about fundamental concepts like pressure, acceleration, gravity, turbulence and energy. But there were also three very important rules that apply generally to all kinds of science and engineering:

  1. Reach for the stars. A cliché, but it’s true. John F. Kennedy said America continued to pursue the ambitious space race goals, not because they are easy, but because they are hard. Because it is hard, 90% of science and engineering doesn’t even make it off the launchpad (let alone into orbit) and it often goes horribly, horribly wrong. That’s the deal – but it shouldn’t stop you reaching high. Sometimes you make giant leaps.
  2. It’s not rocket science. Another tired cliché. This one has become so well worn that there is a saying amongst NASA rocket scientists at the famous Jet Propulsion Laboratory (JPL) in California :

    “It doesn’t take a rocket scientist to be a rocket scientist.” [2]

    So despite appearances to the contrary, many kinds of science (and engineering) aren’t rocket science. You don’t always need big, complicated, expensive and state-of-the-art technology accompanied by armies of highly qualified experts. Sometimes you do, but not always. All that water rocketry requires is an empty drinks carton, a bicycle pump and some water – it really isn’t rocket science [3].

  3. It should be fun. As you probably already know (or can imagine) water rocketry is great fun. Science and engineering are fun too – it’s all too easy to get bogged down in the inevitable politics, bureaucracy and other sideshows – but at the end of the day the net effect should be fun with a fantastic big capital F. If you’re not having fun then Houston, we’ve had a problem. Something, somewhere needs fixing.

The thing about these rules is that they apply to all kinds of science, technology and business [4]. So if you’re a scientist or an engineer of some kind, or even a budding rocket scientist or entrepreneur, it’s worth stopping to ask yourself three simple questions: 1) Are you aiming high and charting unknown territory? 2) How much do you really need all that complicated technology? 3) Are you having fun?
