Science for Marathon Monday

Update: On Monday afternoon at 2:56pm, two explosions occurred near the finish line of the Boston Marathon. In light of these events, PLOS ONE would like to express our deepest sympathies for the victims and families affected by this tragedy.

 

Still procrastinating on those tax returns? If you have finally filed and are looking to blow off some steam, maybe a 26.2 mile run will do the trick! Today on April 15th, over 27 thousand people will lace up their sneakers, warm up their muscles and prepare for one of the world’s oldest races, the Boston Marathon.

Vasque Mindbenders after a muddy trail run in the hills of Griffith Park.  (c) 2011 Geoff CordnerThe very first Boston Marathon was held in 1897 and was then known as the B.A.A. Road Race. Originally 24.5 miles in length, the race was extended to 26.2 miles in 1924 to conform to the Olympic standard. Since that first race day which featured 15 runners, the marathon has grown immensely, with 26 thousand people participating last year.

In honor of the 117th marathon or whatever race you may be running today, here are some recently published articles featuring the sport:

In a paper published this February, researchers have determined the cause of runners fatigue during a marathon in warm weather. These authors recruited 40 amateur runners to test their fatigue and measure their pace during the race. Through their analysis, the authors found that participants who felt the greatest fatigue had elevated levels of blood markers of muscle breakdown. There is still further research to be done to find if this muscle damage is due to mechanistic or metabolic factors.

But what effect does warm weather have on a marathon? In another recent article, authors investigated whether climate change has affected the winning times of the Boston Marathon.  The authors found the temperatures between 1933 and 2004 did not consistently slow winning times on race day. However, the analysis also indicated that if temperatures warmed by 0.058°C a year, we would have a 95% chance of detecting a slowing of winning marathon times by 2100. And if average race day temperatures had warmed by 0.028°C a year (a mid-range estimate) we would have a 64% chance of detecting a decline in winning timings by 2100.

This analysis gives us some insight on how running may change in the future, but have you ever wondered what the sport was like 30,000 years ago? Unlike current shoe wearing athletes, our ancestors were barefoot runners and so are other modern human populations, including the Daasanach. In an article published this year, researchers have investigated the foot strike patterns among barefoot runners in northern Kenya. Data was collected from 38 adults, who ran at their own speed and distance. The authors found that not all the barefoot runners landed on their fore- or mid foot, but the majority landed on their heels first. This observation dismisses the original hypothesis that the barefoot runners would land on the fore-or mid foot, and suggests that there may be a number of other factors which influence foot strike patterns.

Access Copyright lawsuit: are some of us inadvertently suing our employers?

The latest Access Copyright lawsuit against York University and renewed attempt to force every post-secondary and K-12 to pay Access Copyright’s tariff is an opportunity to look at their “intellectual property” and approaches in new ways. For example, it just dawned on me that academic authors may be in a position of indirectly suing their employers, through their publishers, represented by Access Copyright and other members of the International Federation of Reproduction Rights Organizations (IFFRO) as well as pushing for draconian tracking regimes that threaten our own academic freedom.

For example, one of the members of the IFFRO is the UK’s Copyright Licensing Agency (CLA). One of the members of CLA is the Association of Learned and Professional Society Publishers (ALPSP). Members of ALPSP obviously are learned and professional society publishers, including the American Chemical Society (ACS) Publications Division, Cambridge University Press, Elsevier Ltd., Oxford University Press, Sage Publications, and Taylor & Francis, to name a few.

Scholars working at York University publish their work in journals owned by ALPSP members, who then work indirectly through the IFFRO and Access Copyright to sue the employer of their authors, York University. I have a strong hunch that there are some very interesting legal and strategic implications here.

#animalgarden Bottom-up Ontologies in Physical Science

On Thursday (2013-04-11) I was invited by Fiona McNeill to give a 5-minute talk on ontologies at Edinburgh (http://dream.inf.ed.ac.uk/events/ukont-13/2013_workshop_program.html ). The workshop aims included:

Amongst other areas of interest, there will be a particular focus on creating and using open data. The program and audience is intentionally very diverse; the aim is to cover areas from many disciplines. We are particularly interested in bringing together those creating and developing the technology with those using the technology in industry, government and public organisations.

A short talk requires special preparation. No point in trying to prove theorems in first-order logic. In fact I argue that this is far too complicated and unnecessary for physical science. So #animalgarden offered to make a presentation. (They didn’t have time to have a proper shoot so they have re-used old slides and there’s no music yet). The slides are at http://www.slideshare.net/petermurrayrust/ontologies-in-physical-science – there are a few snapshots here. (Conventional chemists can read the words – which are deadly serious – and ignore the animals L )

The problem is that much of physical science doesn’t even use common identifiers or vocabularies. So the problems are people-problems, not technical ones.

There are a very few chemical ontologies but few people use them and this is even more problematic in materials science. This domain is probably the easiest of all sciences to create ontologies for but paradoxically it hasn’t happened. Crystallography (www.iucr.org/cif) is a shining exception but computational chemistry has nothing.

So a number of us are joining together to create “bottom-up ontologies”. Firstly small coherent group systematize the description of what they do in semantic form. Computational chemistry is particularly well suited to this – the programs (codes) have implicit semantics (because the code works and gives the right answers)! Then the community looks at the resultant collection of ontologies and systematizes them where they have the same concepts. In these cases there is a common entry in a communal ontology.

When this isn’t possible the ontologies create machine-readable conventions.

But few computational codes have explicit ontologies. Some define a few of the terms in their manuals, but they aren’t linked to the programs. We’ve developed Chemical Markup Language a which does exactly this. Each code (NWChem, Hyperchem, DLPOLY…) creates their own ontology using a common syntax (CML) but their own identifiers.

There are immediate benefits – the program output becomes semantic and can be re-used for analysis, aggregation, etc. If two groups have ontologies they compare notes and create a toplevel dictionary. As more groups join, the top-level dictionary gains more knowledge and acceptance from the community. And everyone has a feeling of ownership.

We are delighted that Hyperchem http://www.hyper.com/ have recently offered to join in the communal effort. See http://blogs.ch.cam.ac.uk/pmr/2011/11/02/searchable-semantic-compchem-data-quixote-chempound-fox-and-jumbo/ for an overview of the collaboration with PNNL. And http://blogs.ch.cam.ac.uk/pmr/2013/02/03/topics-and-links-for-my-talk-on-semantic-web-for-materials/ for work with CSIRO. And some idea of the great contribution from Kitware http://blogs.ch.cam.ac.uk/pmr/2013/03/01/liberation-software/
