Blogs:

• programming4scientists.com - tricks for scientists entering the world of programming
• mailund on the Internet - nice blog on programming, population genetics, simulations
• Open-Bio news - news from the project that hosts bioperl, biopython, etc..
• FinchTalk - this one is from a company, but it is interesting and technical worthy of reading it.
• Fisheye Perspective - very interesting with news on synthetic biology and else - the author is very active in many bioinformatics communities. note: I suggest you to register to the feeds directly
• 88 Proof Synthetic Biology
• Learning R - tips to learn R
• BioCS
• MentalIndigestion
• PDB - MOlecule of the Month
• The molecule of the Month - similar style to pdb's, but different authors

Moreover, I also find useful to follow the blogs from many bioinformatics services or databases:

• NCBI's news
• Uniprot's news
• Plos Computational Biology
• Gene Ontology news
• Ensembl news

mine of course ! :-) http://plindenbaum.blogspot.com

Shameless plug for the bioinformatics subreddit (of which I am a moderator).

There are so many great blogs out there, I love Openhelix blog, and many others already listed. But reading all blogs takes ages, though I have everything fed into my Google Reader.

That's the reason why last week we started our new community-based project biotricks.net, which is a meta-blog linking out to interesting tips, tricks, and tools for bioinformaticians but also hosts own articles, scripts, code lines, etc.

At the moment it is quite basic, but like BioStar it will become more interesting the more people are using it.

So please support and contribute to this project. Thanks.

A friend of mine is a very active blogger in bioinformatics. This is his blog site

Fisheye Perspective

He has also complied a list of bioinformatics and chemo informatics blogs which are very popular. some of you might be interested in it.

30+ Blogs about Bioinformatics and Chemoinformatics Programming

Here is one that I follow, but I'm interested in adding more blogs to my feed:

• Blue Collar Bioinformatics

Getting genetics done, covers more than just bioinformatics and is a bit heavy on the GWAS but overall is a well-done blog.

Maybe not The Greatest but these few are covering next gen sequencing:

http://www.massgenomics.org/

http://www.fejes.ca/labels/DNA.html

http://omicsomics.blogspot.com/

Shameless plug for the OpenHelix blog. We talk about databases and resources in genomics/bioinformatics for the end user/experimental biologist, have tips of the week, etc.

In addition to some mentioned above, I like business|bytes|genes|molecules

Very large list of bioinformatics blogs from the now defunct Nodalpoint wiki

I like the OpenHelix Blog. :D

A lot has been written above, so I'll add something different. One reason to follow a blog is to be a part of the conversation or simply to "listen in." This is why we go to conferences. And so, I think that one should also be on Twitter in order to do the same - listen and add to the conversation. Clearly, Twitter and a blog are different formats and come to you in different ways, but they are both useful tools in getting you connected to other people and their ideas, as well as putting yourself into the conversation.

Well, more than "favourite" blog I can list the ones I like (this is, the ones that passed the filter and I'm still following). Apart from Giovanni's and Pierre's, and other more technical blogs already mentioned, I'm interested in the sequencing technologies, personal genomes and publication ethics. This is then my small list:

http://nsaunders.wordpress.com/ - Bioinformatics and other stuff

http://cameronneylon.net/ - On communicating science

http://www.genomesunzipped.org/ - On personalized Genomics

Can't help to add a shameless plug to our group's blog on Computational OncoGenomics: http://bg.upf.edu/blog/

A few not mentioned yet here that are in my google reader are:

Hi, I found some interesting posts on http://www.biotricks.net/ The blog is quite new, and there are many interesting guides, for beginners and the curious. Definitively will keep following it!

RNA-Seq Blog

Weblog on Bioinformatics, Genome Science, Next Generation Sequencing

I just remembered this--there's a good thread on blogs in this arena from the SEQanswers forum:

http://seqanswers.com/forums/showthread.php?t=5024

I am quite keen of some of the in-depth blogs about metabolomics, such as this blog by Gilleain around metabolite identification.

My little contribution to the Bioinformatics Field: http://www.bioinformatics.fr

Macromolecular Modeling Blog

Python for Bioinformatics

As WoA Nicely put: the Macromolecular Modeling Blog other related blogs I read (but don't write at): sort of ranked by relevance to structural bioinformatics:

• Trapped in the USA
• Discount Thoughts
• Byte Size Biology
• In the Pipeline
• Mike's Spacetime
• The Curious Wavefunction
• Public Rambling
• Circle of complexity (new home of freelancing science)
• Bleeding Edge Biotech
• The Chemical blogspace Blog
• Mining Drug Space

Some update more routinely than others.. What other computational structural biology blogs you know ?

http://www.biotricks.net/ is definitely worthwhile to try.

http://www.bioinformatics.fr/

We started a blog at http://www.homolog.us to write on transcriptomics and next-gen sequencing. Here is a brief description of our objectives.

This one has just started but contains interesting media files and source code:

http://bio-tools.org/

I like Getting Genetics Done available here: http://gettinggeneticsdone.blogspot.com/

Every thing and anything related to Bioinformatics ...Jobs in Bioinformatics, Bio Java, Bio Ruby, Sequencing, Free Downloads, Video tutorials

http://amitvikram-bioinformatics.blogspot.com/

Biocoders.net is actually mine, additionnaly to a being a blog i am using it as a strong online collaboration tool, synchronizing my social networks with it, it is :

Facebook Linkedin Twitter Github Sourcefoge

Like all in one web app.

Here is what I read on a regular basis:

http://core-genomics.blogspot.com - "personal blog written by James Hadfield who runs a Genomics core facility Cambridge" - lots of interesting technical details about next-generation sequencing

http://massgenomics.org - medical genomics blog by Dan Koboldt, a staff scientist at the Genome Institute at Washington University

http://www.genomesunzipped.org - popular blog run by several genomics researchers

http://blog.openhelix.eu - as mentioned in other responses, this covers tutorials and FAQs for common bioinformatics tools

http://gettinggeneticsdone.blogspot.com - as mentioned in other responses, a well-maintained blog written mostly by Stephen Turner (Bioinformatics Core director at University of Virginia)

Also, I am baised, but I also have my own blog:

http://cdwscience.blogspot.com - My Biomedical Informatics Blog

The Genome Factory

I've never added mine, which is bioinfoblog.it Topics: bioinformatics best practices, planning, genetics, R, dplyr, ontology enrichment, bioinformatics in the pharma industry.

More for viruses: Bioinformatics I/O - Tips && tricks from a cluster of bioinformaticians: http://bioinformatics.cvr.ac.uk/blog/

https://www.r-bloggers.com

My bioinformatics blog: https://www.dna-ghost.com/. Welcome to comment. It covers bioinformatics and cancer genomics.

It can't be regarded as blog, but it's hub of bioinformatics software and databases https://omictools.com/.

My preferences are:

RNA-seq Blog

Genomeweb

BiosmartBrief

NGS

All these blogs are free and I find them very useful.
