The Groovy Side of Phobos.


From 10 years of mission to Mars and high resolution pictures, ESA (European Space Agency) just released this amazing video of Phobos, the largest moon of Mars. As you can see, it’s pretty groovy and the video is really impressive too. The parallel grooves are actually a stunning feature of Phobos. How it got scratched that way is a good question, and of course nobody knows, yet.

Fun Math, Science Blunders and Space: Some Reading for the Winter

With the end of the year upon us, it is good time to change gear and indulge in some relaxing reading. Here is a book selection just for that (it also makes for great gifts if you are falling short). So, sit back and enjoy (and leave a comment if you have more suggestions).

The Joy of x: A Guided Tour of Math, from One to Infinity by Steven Strogatz.

The secret code behind the genetic code. Well...

The secret code behind the genetic code.

A second code hiding in the DNA?

"Scientists have discovered a second code hiding within DNA". That's the headline about the results of a study published today in the journal Science. It shows that 15% of the codons in humans have a dual function: the traditional coding of amino acids and, that’s the novelty, the control of gene expression. Those dual codons were dubbed duons.

The super-planet that should not be there.

HD 106906 b is the newest exoplanet in the ever growing catalogue of extrasolar worlds. What's special about this one is that it throws a wrench into the planet formation theory, and leave astronomers slightly puzzled.

How to Manipulate Big Data with One-liner Commands


Here is a list of simple one line awk, grep and sed commands that are very useful when dealing with big large datasets. This is particularly true for any work involving genomics, sequencing, etc. I have used them numerous time with datafile generated by Plink, for genome assembly, protein and gene databases.
