I have fixed two small bugs in the blastgrep tool (see below), and the version number has been increased to 1.0.2. This update is recommended to everybody who downloaded the previous version of blastgrep. The new version of blastgrep can be downloaded using this link.

There’s a lot of stuff going on at the moment, and I will not be able to make it to this event myself, but I encourage everyone interested in the future of science that is able to to go there. It is important, interesting, and not expensive. Copy/paste from the website:

Join us at the first Open Science Summit, an attempt to gather all stakeholders who want to liberate our scientific and technological commons to enable an new era of decentralized, distributed innovation to solve humanity’s greatest challenges. (…) The Open Science Summit is the first and only event to consider what happens throughout the entire innovation chain as reform in one area influences the prospects in others.

Tickets are available until Wednesday (the 28th), and the event runs from July 29 to 31 at the International House Berkeley, CA. Please be there for me and represent a movement towards increased openness in science. See this previous post by me for my opinion on things.

I have added some software I have written to this page (see link to Software at the top of the page). Among these is the useful little Unix/Linux utility blastgrep, which functions as a grep adopted for extracting useful information from BLAST-reports. I wrote it recently as I increasingly use complicated combinations of piped Unix-commands to do the same thing. blastgrep makes it all more easy. Use it as you wish, and if you do, please tell me about its bugs (hopefully none…)

I listened to a great talk by Alex Bateman (one of the guys behind Pfam and Rfam, as well as involved in HMMER development) at FEBS yesterday. In addition to talking about the problems of increasing sequence amounts, Alex also provided some reflections on co-operativity and knowledge-sharing – not only among fellow researchers, but also to a wider audience. The starting point of this discussion is Rfam, where the annotation of RNA families is entirely based on a community-driven wiki, tightly integrated with Wikipedia. This means that to make a change in the Rfam annotation, the same change is also made at the corresponding Wikipedia page for this RNA family. And what’s the use of this? Well, as Alex says, for most of the keywords in molecular biology (and I would guess in all of science), the top hit on Google will be a Wikipedia entry. If not, the Wikipedia entry will be in the top ten list of hits, if a good Wiki page exists. This means that Wikipedia is the primary source of scientific information for the general public, as well as many scientists. Wikipedia – not scientific journals.

The consequence of this is that to communicate your research subject, you should contribute to its Wikipedia page. In fact, Bateman argues, we have a responsibility as scientists to provide accurate and correct information to the public through the best sources available, which in most cases would be Wikipedia. To put this in perspective (and here I once again borrow Alex’ words), if somebody told you ten years ago that there would be one single internet site that everybody would visit to find scientific information, and where discussion and continuous improvement would be allowed, encouraged and performed, most people would have said that was too good to be true. But that’s what Wikipedia offers. It is time to get rid of the Wiki-sceptisism, and start improving it.

And so, what about the future of publishing? Bateman has worked hard to form an agreement with the journal RNA Biology to integrate the publishing into the process of adding to the easily accessible public information. To have an article on a new RNA family published under the journal’s RNA families track, the family must not only be submitted to the Rfam database, but the authors must also provide a Wikipedia formatted article, which undergo the same peer-review process as the journal article. This ensures high-quality Wikipedia material, as well as making new scientific discoveries public.

I don’t think there’s a long stretch to guess that in the future, more journals and/or funding agencies will take on similar approaches, as researchers and decision-makers discover the importance of correct, publicly available information. The scientific world is slowly moving towards being more open, also for non-scientists. This openness is of extremely high importance in these times of climate scepticism, GMO controversy, extinction of species, and nuclear power debate. For the public to make proper decisions and send a clear message to the politicians, scientists need to be much better at communicating the current state of knowledge, or what many people prefer to call “truth”.

Here at FEBS, I am for the first time doing the reflection that sex obviously can sell anything – even biology. With a mixture of disgust and interest of how much more attention it actually brings, I have been watching the two “antibody princess” girls that’s been running around at the conference, trying to sell antibodies. Unfortunately, I have not brought my camera, so all I have is these pretty bad pictures taken with my phone. I will not name the company behind this, as I do not want to function as an inappropriate extra advertising space for them, but it’s interesting to note that the “sex sells” thing has reached into molecular biology. And it makes me wonder what’s next…

The time is running out if you want to attend to the workshop session on mapping signal transduction, hosted by Stefan Hohmann and Marcus Krantz, which I will take part in. Deadline is on the 15 of May, so register soon if you have not already done. You can find all important info here.

The workshop will take place on June 29:th, between 13.00 and 15.30. The goal is to show some visualisation strategies for signal transduction pathways, and how to use pathway maps as a base to create mathematical models. There will be a brief introduction to mapping and modelling and to the software used (Cytoscape, CellDesigner). This will be followed by independent work with a set of small case studies that demonstrates the basic methodology. I will take part in answering questions and assisting during the case study part.

If you did not already know, or at least suspected, that pesticides used in agriculture could have a negative impact on species diversity, there is now proof. In this article:

• Geiger et al. “Persistent negative effects of pesticides on biodiversity and biological control potential on European farmland“. Basic and Applied Ecology, Volume 11, Issue 2, March 2010.

the result of a joint study in eight European countries, we present that biodiversity indeed takes a strike by the use of pesticides, at several levels. Also, actions are needed for a change in the structure of the large-scale agriculture. And why do I say we? This isn’t exactly microbiology, is it? Well, this is the first publication related to the field assistant work I did during the Summers of 2007 and 2008. There is more in the pipeline, but this first publication at least shows that there are considerable risks with the way we use weed control.

My name is Johan Bengtsson-Palme. I am an assistant professor at the Division of Systems Biology at Chalmers University of Technology in Gothenburg and the Sahlgrenska Academy at University of Gothenburg, funded by the Wallenberg DDLS initiative. My research group works with data driven microbiology and microbial ecology, primarily focusing on investigating antibiotic resistance, pathogenesis and interactions in bacterial communities through large-scale experimental work, metagenomics and bioinformatics. I also have an interest in molecular taxonomy and improving the quality of reference databases. You can read more about our research interests here.
