A team of interdisciplinary researchers at the University of Texas at Austin (UT Austin) used intertwined DNA strands to store an Esperanto translation of "The Wizard of Oz" with unprecedented accuracy.

UT Austin's Ilya Finkelstein said, "The key breakthrough is an encoding algorithm that allows accurate retrieval of the information even when the DNA strands are partially damaged during storage."

Previous DNA storage methods required repeating the stored data 10 to 15 times, with repetitions compared to remove any insertions or deletions when reading the information.

UT Austin's Stephen Jones said the new technique encodes information in a lattice-like arrangement, requiring data to be read just once; the coding language also avoids sections of DNA that are error-prone or difficult to read.
