High information density for DNA data storage

DNA is a promising medium for data storage. Yet, designing a transcoding algorithm that can achieve high information density (meaning, high number of bytes per gram of DNA) while providing robust error tolerance is still a challenge. In this issue, Ping et al. introduce a codec that achieves an in vivo physical information density that is close to the theoretical maximum, while being robust to various types of errors.

Comment & Opinion

  • The rapidly growing demand to share data more openly creates a need for secure and privacy-preserving sharing technologies. However, there are multiple challenges associated with the development of a universal privacy-preserving data sharing mechanism, and existing solutions still fall short of their promises.
