Scientists have stored audio and text on fragments of DNA and then retrieved them with near-perfect fidelity — a technique that one day may provide a new way to handle the overwhelming data of the digital age.
In a major step toward an era of personalized medicine, researchers reported Wednesday that they have sequenced the complete DNA material of more than 1,000 people from 14 population groups in Europe, Africa, East Asia and the Americas.
The deepest look into the human genome so far shows it to be a richer, messier and more intriguing place than was envisioned just a decade ago. While such intricacies underscore the challenges of tackling complex diseases, they also offer scientists new terrain to unearth better treatments.
In the latest attempt to corral society’s growing quantities of digital data, Harvard University researchers encoded an entire book into the genetic molecules of DNA, the basic building block of life, and then accurately read back the text.
