Three years ago, the stock price of the company GameStop soared over 1,625% in just a week. While it's been speculated the primary cause was unprecedented, organized action among Reddit users using a trading strategy known ...
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 ...
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 ...

An international team of astronomers reports the discovery of a new ultra-faint dwarf galaxy as part of the DECam Local Volume Exploration (DELVE) survey. The newly found galaxy, designated Pegasus IV, has an absolute magnitude ...
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.
