Researchers have successfully stored information in synthetic DNA and then sequenced the DNA to read the data. Nick Goldman and his colleagues from the European Bioinformatics Institute (EBI) encoded all of Shakespeare's sonnets, an audio clip of Martin Luther King's "I have a dream" speech, Watson and Crick's paper on DNA's structure, a photo of the EBI, and an explanation of their data conversion technique. Last year, Harvard molecular geneticist George Church encoded a book he had written in DNA, but EBI's breakthroughs are in the way the data is encoded and its error-correction. From the abstract of their scientific paper published at Nature
We encoded computer files totalling 739 kilobytes of hard-disk storage and with an estimated Shannon information10 of 5.2 × 106 bits into a DNA code, synthesized this DNA, sequenced it and reconstructed the original files with 100% accuracy. Theoretical analysis indicates that our DNA-based storage scheme could be scaled far beyond current global information volumes and offers a realistic technology for large-scale, long-term and infrequently accessed digital archiving. In fact, current trends in technological advances are reducing DNA synthesis costs at a pace that should make our scheme cost-effective for sub-50-year archiving within a decade.

Jan Fröjdman used HiRISE satellite data from Mars to create this beautiful and detailed flyby of the planet. Liz Stinson writes that stitching it together took months. For Fröjdman, creating the flyover effect was like assembling a puzzle. He began by colorizing the photographs (HiRISE captures images in grayscale). He then identified distinctive features in […]
Adult tube site xHamster released its first comprehensive survey of porn viewership in 2016. According to them the most visited category moved from MILFs to Matures (women in their 40s and 50s). They also found that searches for “Melania” beat out “Donald Trump” and “Hillary Clinton” combined.
The Telegraph created an interactive data visualization of cannabis use in countries around the world. Here are the winners: • Iceland – 16.2% (prevalence of use as percentage of population) • US – 16.2% • Nigeria – 14.3% • Canada – 12.7% • Chile – 11.83% • France – 11.1% • New Zealand – 11% […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
