60MB生物医学图像存入DNA！我国DNA信息存储技术取得新突破

Core Viewpoint - Recent advancements in DNA storage technology have led to the development of a new system called HELIX, specifically designed for storing biomedical data, achieving successful storage and recovery of 60MB of spatiotemporal images [1][4]. Group 1: Technological Breakthrough - The HELIX system was developed by a research team led by Professor Wu Huaming from Tianjin University and published in the journal Nature-Computational Science [1][5]. - DNA storage technology is emerging as a potential medium for large-scale data storage, with each gram of DNA capable of storing hundreds of exabytes of data and lasting for thousands of years without power [4]. Group 2: System Architecture - HELIX consists of three core modules: image compression, error correction coding, and image restoration, enhancing the system's fault tolerance and recovery capabilities [5]. - The team optimized existing compression algorithms to address potential base errors during DNA storage, significantly improving the system's reliability [5]. Group 3: Experimental Results - The research team successfully encoded two images totaling 60MB into 130,000 DNA sequences, each containing 183 bases, and successfully recovered the image data using DNA synthesis and sequencing technology [5]. - The study indicates that a DNA storage system tailored for specific data types not only excels in storage efficiency but also demonstrates greater reliability, laying a solid foundation for the widespread application of DNA information storage technology [5].
