Sorry Connotea, it's not you, it's me.

I used to really like Connotea and the idea of being able to easily bookmark and share journal articles was what drove me to encourage many people in my lab to start using it. I truly believed it would evolve into a tool that would be essential for researchers and would be a major improvement to existing methods of tracking new papers.

Well, boy was I wrong. I haven't seen any improvements in Connotea for at least a year including a search engine that would be better replaced by Google. Even worse for the past few months Connotea website has been getting slower so that instead of looking up my papers there I just go back to searching Pubmed. Finally, for the past few days Connotea seems completelly useless so that papers I was hoping to cite for my near future thesis writing days are inaccessible.

Like any bad relationship I was hoping it would get better over time, but I have waited long enough and I'm breaking it off before I get any more committed. If the site does ever become accessible again I plan on exporting my bookmarks and taking them elsewhere. Any recommendations?

IslandViewer

My most recent research has resulted in website for viewing predictions of genomic islands (GIs), large regions of horizontal gene transfer, in bacterial genomes. IslandViewer integrates three different methods of GI detection IslandPick, SIGI-HMM, and IslandPath-DIMOB. SIGI-HMM and IslandPath-DIMOB use sequence composition bias to detect GIs and were found to be the most accurate in a recent publication. IslandPick is a method I recently developed that uses comparative genomics to find GIs by identifying regions that are present in one genome but absent from several related genomes.


Predictions for all three tools are pre-computed for all sequenced bacterial genomes (those available from NCBI Microbial genomes). Also, users can submit their own newly sequenced genome for analysis and receive an email when complete (usually within a couple of hours).

Update:IslandViewer has been published in Bioinformatics!

Any feedback or comments on the design or usefulness on the website is appreciated!

My New Little Scientist

My first baby was born on Nov. 5th weighing in at 7lbs. After much debate during the pregnancy my wife and I decided to name him Gavin Nathaniel Langille. The first week was tiring of course, but I don't think I really noticed due all the excitement and the newness of it all. However, now that I am in the middle of the second week it is starting to catch up with me!

One thing about having the baby is that I am very focused on finishing my PhD and I am in serious job hunt mode. People keep asking me about what type of position I am looking for. The most likely is a post-doc in academia, but I haven't ruled out taking a job in industry. I have at least one post-doc position and one bioinformatics scientist position industry that I plan on applying by next week.

I would have to say that the biggest limitation for job hunting is location. Having a baby really is drawing me to move closer to home, Atlantic Canada, but I am still keeping a fairly wide search distance down to the Boston area.

Microbial Genomics Conference (Last Update)

I promised in a previous post to add more details about the Microbial Genomics conference in Lake Arrowhead. However, my wife went into pre-term labour, and is now on bed rest so I am a little short on time. I did give a conference review at a recent lab meeting so I thought I would post that as a quick substitute.

Review of Arrowhead Conference

I was hoping to write this during the conference, but every talk I went to was really interesting and I ended up not using that time for blogging. However, there is at least one talk that I wanted to mention before I forgot to much.

I thought the most interesting talk was from Kim Lewis, who describes "persistor cells" as those bacteria that lay dormant in a population. These persistors are resistant to antibiotics because they are essentially shut down and passivly allow antibiotics to simply wash over them as opposed to normal bacteria cells that actively block or pump out antibiotics. Lewis also showed that late samples taken from cystic fibrosis patients had high levels of persistor cells. Kim then discussed unculturable bacteria (of which 99% of bacteria are) and suggested that when plated on media that these are actually dormant and not dead. To support this Kim showed that by innoculating an unculturable sample with E.coli caused growth of an unculturable strain around the E.coli spot. He later found a mutant that did not cause the effect and identified the key gene to be a sideophore. Lewis ends with this little tidbit, "Dormancy is the default mode of bacterial life". I find this really interesting because it suggests that most bacteria depend on a few bacteria to signal when their surrondings are optimal for growth.

There are a couple of more talks that I hope to blog about in the next day or two.

Microbial Genomics

I have been at Lake Arrowhead since Sunday for the 16th International Microbial Genomes Conference and I have to admit I am quite impressed. I think this conference has solidified in my mind that large conferences can't compete with smaller conferences. Let me list the reasons why in order of importance:

1. Food - in almost all cases the larger the group of people the worse the food will be. Now you may think I am slightly joking around saying that this is the most important, but I am quite serious. There is nothing worse than having to eat some cafeteria style food and then have to sit through 2-4 hours of talks with a cramping/rumbling/starving belly. Also, I find meals are the best place to meet and have discussions with other scientists.
   
2. Meeting people. You get a chance to meet almost everyone you want to without having to hunt them down like a gazelle. I really detest pouncing on a speaker as soon as they are done a talk. It is much nicer to see them at a break or at a meal (see above) and introduce yourself and ask a question then.
3. Better science. I find at smaller conferences the talks have been hand selected and tend to have a better line up of speakers
   
4. Location, location, location. Smaller conferences tend to have their meetings at nicer locations.
5. Beer & Wine - From my experience alcohol tends to be cheaper (or free) at smaller conferences which always makes everyone happy and tends to get scientists to loosen up some.
   

Mygazines

I recently found out about Mygazines.com, a website that allows users to upload and share scanned copies of magazines. This new form of digital piracy is getting the copyrights enforcers attention. I figured the site would be fairly lame with barely readable faded copies of old obscure magazines, but after checking out the site I was quite impressed. The images are clear and the website design is as good as any new social website. Over my lunch break I checked out the September issue of Discover and read a great article about personal DNA testing (p35). Personally, I don't see that many people cancelling their subscriptions, since most people still prefer to read from real paper. However, I was curious to see if any scientific journals were on the site. I figured some of the big ones such as Nature or Science might be, but ater a quick search it seems there are not that many scientists uploading yet. Of course I have access to all the science journals I need through my university, but I wonder if scientistis that don't have access would use such a source for information?
