Scientists unlock a faster, cheaper way to store data on DNA
Using DNA methylation, scientists store data faster and cheaper.
Scientists at Peking University have developed a method to store data using DNA methylation. This approach allows for rewriting data onto existing DNA strands, bypassing the need for elaborate de novo synthesis, which is typically slow and expensive.
By creating 700 DNA "movable type" components, they demonstrated this technique by encoding images and text on existing DNA. Though it is currently slow compared to digital storage, it surpasses previous DNA storage methods in terms of cost-effectiveness.
Additionally, an app called iDNAdrive supports this new technique, allowing individuals without biotechnology expertise to manually encode data. This advancement suggests a pathway for broader accessibility and potential commercial viability in DNA data storage.
