Four new DNA letters double life’s alphabet

The DNA of life on Earth naturally stores its information in just four key chemicals — guanine, cytosine, adenine and thymine, commonly referred to as G, C, A and T, respectively. Now scientists have doubled this number of life’s building blocks, creating for the first time a synthetic, eight-letter genetic

CRISPR to Build Computers Inside Human Cells

A CPU of biological components A team of researchers led by Martin Fussenegger, Professor of Biotechnology and Bioengineering at the Department of Biosystems Science and Engineering at ETH Zurich in Basel, have now found a way to use biological components to construct a flexible core processor, or central processing unit

DNA Computing

DNA computing is a branch of computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional silicon-based computer technologies. Research and development in this area concerns theory, experiments, and applications of DNA computing. The concept of DNA computing was first introduced in 1994. It deals with the

Programmable DNA - Three-dimensional cages

The central goal of nanotechnology is the manipulation of materials on an atomic or molecular scale, especially to build microscopic devices or structures. Three-dimensional cages are one of the most important targets, both for their simplicity and their application as drug carriers for medicine. DNA nanotechnology uses DNA molecules as

Malware running on CT/MRI machines can inject realistic images of cancerous growths.

One of the problems with convincing people to take computer security seriously is that it’s, in a word, boring. Every now and then, however, someone demonstrates a flaw with the potential to break through the walls of ennui surrounding the topic and register with the public consciousness. Israeli researchers

Synthetic DNA Storage

DNA can store digital information in a space that is orders of magnitude smaller than data centers use today. It's one promising solution for storing the exploding amount of data the world generates each day, from business records and cute animal videos to medical scans and images from outer space.
