Hone your fundamental understanding of computer systems by completing this online course called NAND to Tetris. The idea is to develop each fundamental unit that goes into making computer programs a ...

(Nanowerk News) A team of University of California, San Francisco (UCSF) researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to ...

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 ...

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 ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

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 ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...
