Microsoft Sets DNA Data-Storage Record: 200 Megabytes

Researchers store Ok Go! music video, great works of literature, and more in a dab of DNA

Three weeks ago, we reported on a meeting of the minds in Virginia, where experts discussed the plausibility and requirements of using DNA as a hard drive. As the demand for data storage steadily grows, especially in biomedicine, the dense nucleic acid provides a promising new data depot.

At the time of the meeting, a source told us the attendees concluded that the “ambitious goal” of a prototype DNA storage machine was “possible” within five to seven years. Now, it seems they were a bit conservative with that timeline: Yesterday, researchers at Microsoft and the University of Washington announced a new record for the amount of data stored in (and read back out of) synthetic DNA strands.

In a dab of DNA smaller than the tip of a pencil, the team stored 200 megabytes of data—a thousand times more DNA storage capacity than was possible a year ago, they say. “Think of the amount of data in a big data center compressed into a few sugar cubes,” Microsoft proclaimed in a press release. “Or all the publicly accessible data on the Internet slipped into a shoebox.”

In those helical threads of biological material, the team encoded an eclectic range of information: A high-definition version of the popular Rube Goldberg Machine video by the band OK Go!, other forms of digital art, the Universal Declaration of Human Rights in more than 100 languages, the top 100 books of Project Gutenberg, and a seed database from the nonprofit Crop Trust.

At this rate, someday soon we’ll all be reaching over our thumb drives to grab a test tube.

Are You Ready for Workplace Brain Scanning?

Extracting and using brain data will make workers happier and more productive, backers say

Get ready: Neurotechnology is coming to the workplace. Neural sensors are now reliable and affordable enough to support commercial pilot projects that extract productivity-enhancing data from workers’ brains. These projects aren’t confined to specialized workplaces; they’re also happening in offices, factories, farms, and airports. The companies and people behind these neurotech devices are certain that they will improve our lives. But there are serious questions about whether work should be organized around certain functions of the brain, rather than the person as a whole.

To be clear, the kind of neurotech that’s currently available is nowhere close to reading minds. Sensors detect electrical activity across different areas of the brain, and the patterns in that activity can be broadly correlated with different feelings or physiological responses, such as stress, focus, or a reaction to external stimuli. These data can be exploited to make workers more efficient—and, proponents of the technology say, to make them happier. Two of the most interesting innovators in this field are the Israel-based startup InnerEye, which aims to give workers superhuman abilities, and Emotiv, a Silicon Valley neurotech company that’s bringing a brain-tracking wearable to office workers, including those working remotely.
