A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

A DNA-based computer uses simple base-pairing to create AND and OR logic gates. 130 different double-stranded molecules later, the answer to a square root calculation popped out.

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...

Logic gates are the fundamental components of computer processors. Conventional logic gates are electronic – they work by shuffling around electrons – but scientists have been developing light-based ...

How well do you know your logic gates? For their final submission for STEM Projects class, [BKriet] gamified the situation using a Raspberry Pi Pico, some blinkenlights, and a not-insignificant amount ...

DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...
