Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

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 ...

Computers built from DNA will benefit from a design breakthrough that helps them perform complex calculations, and could also lead to biological sensors for detecting diseases. Until now, DNA ...

Researchers have broken speed records for the building blocks of quantum computing, getting them ready to actually build the computers that could revolutionise the world. Quantum computers could come ...

Biocomputing—it’s not just for Star Trek Borgs anymore! Scientists at Johns Hopkins have engineered cells that behave like AND and OR Boolean logic gates, taking an important step toward using living ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
