What happened

Engineered proteins store digital files with 30 times density at one-tenth cost Sadie Harley Scientific Editor Robert Egan Associate Editor Massive volumes of digital data are generated every day from AI training, big data analytics and smart devices.

Why it matters

As conventional hard drives and cloud storage are increasingly constrained by high costs, limited capacity, high power consumption and short lifespans, molecular data storage has emerged as a breakthrough storage alternative.

Common ground

Researchers at The Hong Kong Polytechnic University (PolyU) have pioneered a method that uses engineered proteins to store digital data and, for the first time, completed the full process from data storage to data retrieval in de novo designed unnatural…
