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.

Researchers have been experimenting for some time with the idea that biology can be harnessed to perform computations. Biological systems can amplify and sample a large collection of molecules ...

Researchers have created logic gates – the building blocks of digital circuits – by using a combination of a novel fluorescent probe, DNA molecules and specific enzymes 1. Such logic gates may be ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...

You can use the circuit described in this DesignIdea to estimate voltages across 10- to 100-MΩresistances. It also works for reverse-biased diodes. The common CMOS gates in Figure 1 have aninput ...
