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 ...

New rare 'green bean' galaxy discovered

Astronomers from New Mexico State University (NMSU) and elsewhere report the discovery of a new galaxy of a rare class, dubbed "green bean." The finding, made with the Karl G. Jansky Very Large Array (VLA), was presented ...

Art with DNA—digitally creating 16 million colors by chemistry

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary ...

Magnon-based computation could signal computing paradigm shift

Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount ...

New polar ring galaxy discovered

Japanese astronomers report the detection of a new polar ring galaxy using the data obtained with the Subaru Telescope as part of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). The discovery was detailed in a paper ...

Digital

A digital system is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete, such as numbers, letters or icons, or continuous, such as sounds, images, and other measurements of continuous systems.

The word digital comes from the same source as the word digit and digitus (the Latin word for finger), as fingers are used for discrete counting. It is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography.
