Bioinformatics Open Source Conference 2010 (and a poll)

The 11th Annual Bioinformatics Open Source Conference (BOSC) 2010 is coming up in Boston, July 9-10 2010. The BOSC meetings are a great get-together of a community of programmers who are like-minded in their advocacy of open source code for science, and specifically for bioinformatics. The whole thing is run by volunteers who take a […]

Computational Bridge to Experiments

A bit of background information: this is a meeting I am really happy to be part of, and even more so honored to be a co-organizer. One of my main scientific interests is the prediction of the function of genes and proteins of unknown function. Some background information: we have sequenced more than 1000 genomes […]

Closing gaps

Geek alert: this post for coders. So you sequenced your genome, reached an optimally small number of contigs, they look sane, and now you would like to see what you need for the finishing stage. Namely, how many gaps you have and what are their sizes. UPDATE: “might just be worth clarifying this is for […]

Comparative Functional Genomics: Penguin vs. Bacterium

No, not the flesh-blood-and-feathers penguin, but rather Tux, the beloved mascot of the Linux operating system. Compared with Escherichia coli, the model organism of choice for microbiologists. We refer to DNA as “the book of life”; some geeks refer to it as the “operating system of life”. Just like in a computer’s operating system, DNA […]

Combrex: Computational Bridge to Experiments

Combrex is an exciting new project at Boston University to bridge computational and experimental techniques to functionally annotate proteins. They are hiring, see below: JOB POST We are seeking to hire a creative computational scientist for a transformative project: COMBREX: A Computational Bridge to Experiments. The work will involve building a novel resource that combines […]

AMOS on Ubuntu

AMOS is a suite of genome assembly and editing software. It includes assemblers, validation, visualization, and scaffolding tools.  I have been having some issues installing AMOS on Ubuntu  9.10.  Specifically, Ubuntu 9.10 has gcc 4.4, which breaks the compilation of the AMOS release version. However, the development version has been fixed to accommodate that. If […]

I never metagenomics I didn’t like

“Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.” — Proverbs 27:2 “What-ever” —  Me In PLoS Computational Biology this week, a trio of researchers provides a review of the challenges that metagenomics might ― and already do ― pose for bioinformaticians. The authors refer to metagenomic […]

Paweł Szczęsny in TEDx Warsaw

Pawel on Open Science. Full disclosure: I consider sharing an office with this guy for over a year to be one of the best experiences of my postdoc.

Bioinformatics Blog Carnival #1

Yes! Why should the evolution people have all the fun with their blog carnival? (After all, it is only a theory.) It’s time for bioinformaticians to show what we are made of, and to have a carnival of our own. Bio::blogs had a good run some time ago. I decided to reconnect what is hopefully […]

A sh*tload of data

There are more microbial cells in our body than our own. Those microbes are not just passive hitchhikers or conversely, malicious agents of disease. They affect our well-being and health in a much broader spectrum than simply “bad” or “passive”. Among other things our gut microbes play an important role in digestion, have been linked […]

Bioinformatics blog carnival

Byte Size Biology will be hosting the first edition of the bioinformatics blog carnival. All you bioinformatics bloggers, submit your entries by Mar 9, 2010 23:59:03  EST. Note the 3 second extension I have already given. There will be no more deadline extensions, I’ve been generous enough as it is. The carnival will be posted […]

Ancient Greenlander’s DNA reveals ugly mullet

Seriously, this is what I first thought when I saw the cover of this week’s Nature, and the associated drawings  in the press.  The dude’s haircut seems like it was even bad in the ’80s… 2080 BCE that is, which is when his body is dated. Approximately. A large group of researchers were involved in […]

Short bioinformatic hacks: reading between the genes

In celebration of the biohackathon happening now in Tokyo, I am putting up a script that is oddly missing from many bioinformatic packages: extracting intergenic regions. This one was written together with my student, Ian. As for the biohackathon itself, I’m not there, but I am following the tweets and  Brad Chapman’s excellent posts: Day […]

The polypharmacome

Pharmaceutical companies are always on the lookout for secondary drug targets. After all, if you invest billions developing a single drug, you would be more than happy to sell it as a treatment for two, three, or more different ailments. Sildenafil citrate was developed to treat angina and hypertension, but during phase I clinical trials, […]

Fold.it: wasting time in a good cause

I just spent the better part of a Saturday playing with Foldit. Foldit is an ongoing experiment in finding protein structures by harnessing the power of the mob – or gamers, as is the case here. The player is presented with a backbone & sidechain configuration, with the secondary structures mostly pre-determined. The problem is […]
