DNA Lego bricks enable fast rewritable data storage

DNA data storage may become easier to read and write than before, according to researchers at the University of Cambridge Cavendish Laboratory in the U.K. They report on a technique that can also store encrypted data, as ...

Researchers storing information securely in DNA

Experiments at CERN's Large Hadron Collider generate 15 million gigabytes of data per year. That is a lot of digital data to inscribe on hard drives or beam up to the "cloud."

Encryption is less secure than we thought

Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appeared, ...
