Big data opens doors previously closed to researchers, yet the volume of data sends scientists looking for analytical tools to bring order from the informational cacophony. Prior to tools like Bioconductor, there were few options for working with quantitative data types; a discordant score for deciphering the human genetic code was the result.

Today, genomic analysis machines create a common language for users, and build a worldwide community to foster developers from among subject matter experts. These instruments make beautiful music from a mass of genomic information.

Researchers in Switzerland have taken inspiration from fossils to discover how DNA could be used to reliably store data for over two million years. They stored 83 kilobytes of data — containing the text from the Swiss Federal Charter of 1291 and the English translation of the Method of Archimedes — on DNA, which was subsequently encapsulated in silica to mimic the protective shell provided by fossilized bone.

Sometimes solar eruptions have a benign effect, perhaps only creating a spectacular aurora display. But at other times, they can be very dangerous to life on Earth. Stanford solar physicists Monica Bobra and Sebastien Couvidat have developed live forecasting techniques to provide more time to react.

Last week, iSGTW attended the International Supercomputing Conference (ISC’14) in Leipzig, Germany. The event featured a range of speakers representing a wide variety of research domains. Awards given by PRACE and Germany’s Gauss Centre for Supercomputing highlighted some of the outstanding research on show at the event. And, of course, the new TOP500 list of the world’s fastest supercomputers was announced.

iSGTW recently interviewed Ewan Birney, associate director of the European Bioinformatics Institute (EBI), regarding his keynote talk at the EUDAT 2nd Conference. In this interview, Birney raised the exciting prospect of using DNA as an organic data storage device. But could DNA storage really replace tapes and hard disks for long-term preservation of data? Charles Harvey investigates…

Due to the complexity of modern computational science, increasing software errors in code are causing the retraction of research papers in major journals. Now, the RunMyCode project offers a platform to reproduce a published paper's code and data that may be the key to not only reduce errors, but could open the door to better quality science across all research fields.
