How can we use foxes and rabbits help transmit secret messages? No animal cruelty is necessary - a new technique encodes messages using a predator-prey model normally used to predict the changes in animal populations. This advance in steganography could revolutionize the art of secrecy. More »

Ready for a piece of technology you can rampantly steal for NaNoWriMo? How about secretly encoded E. coli that glow and can be used to send messages? Researchers have developed a way of getting seven strains of the bacteria to fluoresce in seven different colors. You can use them to create a secret message that starts as an apparently empty petri dish - but grows into an encoded message after delivery. They've dubbed the system SPAM: Steganography by Printed Arrays of Microbes, and it only gets cooler from here. More »

The Voynich Manuscript first came to (modern) light in 1912. It is named after Wilfrid Voynich, a rare book dealer who plucked the forgotten tome from a dusty shelf in a Jesuit college near Rome, and made it famous. Illustrations of planets, plants, and 'bathing' women decorate its pages. It is also covered with dense text and what seem to be notes and recipes. Why is it named after a book dealer instead of the person who put so many hours into enriching its 230 pages? Because no one knows who the author is. In fact, no one knows anything about the book.

A new method of data storage that converts information into DNA sequences allows you to store the contents of an entire computer hard-drive on a gram's worth of E. coli bacteria...and perhaps considerably more than that. More »

Imagine a form of encrypted communication so secure that it's physically impossible to access it unless you're actually at the location where you're supposed to hear it. Quantum mechanics makes location-based cryptography possible - without any pesky codes or keys. More »

Generating truly random numbers is notoriously difficult. But now, using a quantum system, researchers have managed to create 42 genuinely random numbers. Their discovery is a major breakthrough for cryptography, and could one day enable truly private communication online. More »

Thanks to quantum computing, we now have a fairly precise idea how much energy a hydrogen molecule gives off. Gone are the days when we had to guess this sort of thing by tossing atoms from hand to hand. More »

In a breakthrough in quantum cryptography, a team of 41 institutions has created the world's largest quantum key distribution network. The network enables them to create the most foolproof system in history for sending secret messages. More »
