Harvard cracks the ultimate archive, DNA

A bioengineer and geneticist at Harvard’s Wyss Institute have successfully stored 5.5 petabits of data — around 700 terabytes — in a single gram of DNA, smashing the previous DNA data density record by a thousand times.

The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0).

To read the data stored in DNA, you simply sequence it — just as if you were sequencing the human genome — and convert each of the TGAC bases back into binary. To aid with sequencing, each strand of DNA has a 19-bit address block at the start (the red bits in the image below) — so a whole vat of DNA can be sequenced out of order, and then sorted into usable data using the addresses.

Cyborgs and body hackers

With the advent of the smartphone, many Americans have grown used to the idea of having a computer on their person at all times. Wearable technologies like Google’s Project Glass are narrowing the boundary between us and our devices even further by attaching a computer to a person’s face and integrating the software directly into a user’s field of vision. The paradigm shift is reflected in the names of our dominant operating systems. Gone are Microsoft’s Windows into the digital world, replaced by a union of man and machine: the iPhone or Android.

For a small, growing community of technologists, none of this goes far enough.

FIXED: The Science/Fiction of Human Enhancement

What does “disabled” mean when a man with no legs can run faster than many Olympic sprinters? With prenatal screening able to predict hundreds of probable conditions, who should determine what kind of people get to be born? If you could augment your body’s abilities in any way imaginable what would you do? From pre-implantation genetic diagnosis to neural implants and bionic limbs, researchers around the world are hard at work developing a myriad of technologies to fix or enhance the human body, but what does it mean to design “better humans” and do we want to?
