Shipud writes "Bioinformatics science which deals with the study of methods for storing, retrieving, and analyzing molecular biology data. Byte Size Biology writes about ROSALIND, a cool concept in learning bioinformatics, similar to Project Euler. You are given problems of increasing difficulty to solve. Start with nucleotide counting (trivial) and end with genome assembly (putting it mildly, not so trivial). To solve a problem, you download a sample data set, write your code and debug it. Once you think you are ready, you have a time limit to solve and provide an answer for the actual problem dataset. If you mess up, there is a timed new dataset to download. This thing is coder-addictive. Currently in Beta, but a lot of fun and seems stable."
